12/23/1996 ---------- [bash-2.0 released] 12/27 ----- configure.in - don't automatically use GNU malloc on FreeBSD, the builtin one is supposed to be better (but doesn't have the debugging hooks) builtins/exec.def - check that full_pathname(command) doesn't return NULL because of inaccessible parent directories support/config.sub - recognize OpenBSD execute_cmd.c - broke the code that opens a file for output redirection when in noclobber mode out into a separate function: noclobber_open(). This tries to avoid race conditions and file replacement between stat(2) and open(2) subst.c - make sure pat_subst does not run off the end of its return string when copying the unmatched portion of the input string 12/30 ----- doc/Makefile.in - don't install readline.3 by default lib/tilde/tilde.c - removed an unnecessary check for string[i] being non-null in tilde_find_suffix 12/31 ----- support/config.{sub,guess} - merged in changes from config.sub in autoconf-2.12 distribution lib/readline/readline.c - in rl_newline, only call _rl_vi_done_inserting and _rl_vi_reset_last if readline is currently in vi mode lib/readline/display.c - corrected a misuse of inv_lbreaks where vis_lbreaks was wanted in the code that decides whether the cursor is at the beginning of an otherwise-empty line 1/2/1997 -------- support/bashbug.sh - fixed a typo, thanks to eggert@twinsun.com aclocal.m4 - new test, BASH_STRUCT_DIRENT_D_FILENO, testing for d_fileno member of struct dirent configure.in - call BASH_STRUCT_DIRENT_D_FILENO config.h.in - new #define for STRUCT_DIRENT_HAS_D_FILENO lib/posixheaders/posixdir.h - only define d_fileno as d_ino if STRUCT_DIRENT_HAS_D_INO is defined and STRUCT_DIRENT_HAS_D_FILENO is not defined. This fixed the problem of compiling getcwd.c on SunOS4.1.4 with cc 1/3 --- lib/readline/complete.c - fix a memory-used-after-freed bug reported by Andreas Schwab configure.in - call BASH_CHECK_SOCKLIB only if getpeername is not found in libc (ac_cv_func_getpeername = no) 1/13 ---- builtins/getopt.h - change #define guard to _SH_GETOPT_H to avoid similar guards in /usr/include/getopt.h (Dec OSF/1 4.x, for example) variables.h - fix assign_array_from_string so that it rejects attempts to assign to readonly variables subst.c - fix verify_substring_values to handle offsets that are past the end or before the beginning (in the case of a negative offset) of the expanded variable value 1/14 ---- bashline.c - fix a problem where any completion after a `cmd` command substitution would inappropriately attempt command completion, even if the previous command substitution was correctly closed builtins/evalstring.c - unwind_protect remember_on_history even if the shell is not interactive, since history can now be used in scripts, and `source' will turn off interactive_shell before calling parse_and_execute jobs.c - new function get_job_by_pid(pid, block) to translate a pid to a job number. The block argument says whether or not to block SIGCHLD jobs.h - new extern declaration for get_job_by_pid builtins/jobs.def - call get_job_by_pid if an argument appears to be a pid rather than a jobspec configure.in - configure --without-gnu-malloc automatically on MachTen 4.x builtins/cd.def - change to mindist() so that a best guess of `.' returns 3, which means not reasonable lib/posixheaders/memalloc.h - changed hpux_9 to __hpux, since the new config stuff doesn't define hpux_9 subst.c - fix parameter_brace_patsub to handle null patterns (doesn't do anything) oslib.c - slight change to bzero replacement support/bashbug.sh - changed TEMP to be /tmp/bbug.$$ as a sop to systems with 14-char file names doc/bashref.texi - add note to POSIX Mode section that the output of `set' when invoked without arguments is sorted when in POSIX mode 1/15 ---- support/recho.c - a couple of changes prompted by a `gcc -Wall' subst.c - changed ASSIGN_RETURN macro to use the do...while(0) idiom to avoid problems with its multiple statements builtins/setattr.def - a bad identifier given to readonly or export without an assignment statement (e.g. `readonly a[5]') is an error, but not an assignment error (i.e., return EXECUTION_FAILURE rather than EX_BADASSIGN) tests/{{array,new-exp}.,tilde-}tests - added `set +o posix' at the beginning to disable POSIX mode, which causes some of the tests to fail. Some systems (e.g. LINUX-FT), set POSIXLY_CORRECT by default tests/test-tests - added a warning if $UID is 0 to the effect that the test suite should not be run as root - worked around the `noread' and `nowrite' tests failing when run as root test.c - began removing the remains of the STANDALONE code, since test is included in GNU shellutils 1/16 ---- lib/readline/{readline,display}.c - a couple of slight changes to build on Win95 using djgpp (reported by x-aes@telelogic.se) Makefile.in - changed TERMCAP_LIBDIR to TERM_LIBDIR, so building the termcap library (if necessary) should work now bashline.c - new function: quote_word_break_characters(), to backslash-quote characters in a filename that the readline completion code would treat as word breaks - change bash_quote_filename to call quote_word_break_characters if the completion quoting style says to use backslashes - add `:' to rl_filename_quote_characters, since it's part of filename_word_break_characters lib/posixheaders/posixjmp.h - new file, with half of bashjmp.h - posixjmp.h and lib/readline/posixjmp.h are symlinks to this file bashjmp.h - include "posixjmp.h" for possible redefinitions of setjmp/longjmp and procenv_t 1/17 ---- shell.c - bad options now cause the standard shell usage message (a subset of what `bash --help' prints) to be displayed on stderr trap.c - don't free the trap command for a DEBUG trap in restore_default_signal if SIG_INPROGRESS is set -- there's already a pointer saved to the old value in _run_trap_internal. This makes bashdb run better, too examples/bashdb/bashdb.{pre,fns} - a couple of minor fixes; it actually has a chance of working now 1/21 ---- config.h.in - add a define for , HAVE_DLFCN_H configure.in - look for , define HAVE_DLFCN_H if found builtins/enable.def - include only if HAVE_DLFCN_H is defined lib/readline/display.c - renamed clear_to_eol to _rl_clear_to_eol and made it global, so other library files (readline.c) can use it - new function _rl_clear_screen, to clear the screen with the right termcap escape sequence lib/readline/readline.c - call _rl_clear_to_eol and _rl_clear_screen instead of using tputs - extern declarations for _rl_clear_to_eol and _rl_clear_screen 1/22 ---- mailcheck.c - fixed a problem in make_default_mailpath() where a slash was not added between the default mail directory and the username 1/23 ---- stringlib.c - added a fourth parameter to ansicstr: the length of the returned string externs.h - changed declaration of ansicstr parse.y - changed call to ansicstr -- saves a call to strlen builtins/echo.def - changed call to ansicstr - if do_v9 is non-zero, use putchar to output the string instead of printf, since there may be embedded NULL characters doc/{bash.1,bashref.texi}, builtins/trap.def - modified the `trap' documentation to make it clearer that trap takes multiple signal specs as arguments jobs.c, nojobs.c, jobs.h - renamed initialize_jobs to initialize_job_control, added an argument (force) jobs.c - set shell_tty to fileno(stderr) in initialize_job_control if the shell is not interactive. This fixes the problem of bad tty pgrps when monitor mode is turned on in a non-interactive shell sig.c - made initialize_terminating_signals do only that; moved the rest of the code that used to be there into a new function: initialize_shell_signals, which calls initialize_terminating_signals if the shell is interactive - initialize_terminating_signals is now extern - made reset_terminating_signals return immediately if termsigs_intitialized is zero, meaning that initialize_terminating_signals has not been called sig.h - new extern declaration for initialize_terminating_signals trap.c - call initialize_terminating_signals from set_signal if sig is EXIT_TRAP and the shell is not interactive. Since the terminating signals do not need to be initialized until a trap on exit is set, not doing that at startup should result in a speed increase for scripts execute_cmd.c - save and restore command->flags in time_command, so you can use `time command' in a loop 1/24 ---- lib/readline/display.c - fix redisplay code to wrap correctly if the prompt is longer than the screen width (reported by bos@Eng.Sun.COM) lib/readline/undo.c - don't include , it's not needed lib/readline/{util,readline}.c - include "posixjmp.h" instead of - readline_top_level is now a `procenv_t' instead of a `jmp_buf' (now readline uses the correct posix semantics for preserving the signal mask and other things across longjmp) parse.y - fixes to push_string/pop_string to make them more general -- they now can be used generally, instead of having to be associated with an alias being expanded - fixes to the parser so that it parses (( ls abc; ls def); ls ghi) as a nested subshell command for backwards compatibility. Broke the double-paren expression parsing off into a new function: parse_arith_cmd, called from read_token when a `((' is seen. If it looks like an arithmetic command, return `let' and set things up so that the expression is returned as a double-quoted string by the next call to read_token. If it's a nested subshell, push the text we parsed onto the list of strings for later consumption and return `(' lib/glob/glob.c - fix glob_vector so it doesn't short-circuit checking a filename if it starts with a `.' and the pattern starts with `\.' (if noglob_dot_filenames is set). This makes `".junk2"*' match `.junk2.txt' correctly 1/27 ---- support/bashbug.sh - ask for confirmation before sending the bug report builtins/fc.def - when editing and re-executing a multiline command, make sure current_command_line_count is initialized and then incremented for each line read from the file so that the lines added to the history list by fc_replhist and fc_addhist obey the `lithist' and `cmdhist' shopt options. Reported by tibbitts@pb.seflin.org 1/28 ---- lib/readline/readline.h - added a couple of extern declarations for variables described in the documentation but heretofore undeclared builtins/ulimit.def - try to catch some classes of integer overflows before calling set_limit 1/29 ---- parse.y - push and pop a `(' delimiter while parsing a $(...) construct, so the history code doesn't try to inappropriately add a `;' when a newline appears in the `...' aclocal.m4 - new macro, BASH_STRUCT_WINSIZE, which looks for `struct winsize' in (or one of the files it includes) configure.in - call BASH_STRUCT_WINSIZE - slightly reorganized the calls to bash-specific macros config.h.in - add an `#undef STRUCT_WINSIZE_IN_SYS_IOCTL' jobs.c, nojobs.c - only look in sys/ptem.h for struct winsize if STRUCT_WINSIZE_IN_SYS_IOCTL is not defined to cpp 1/30 ---- .{distribution,patchlevel} - renamed to _{distribution,patchlevel} configure.in - create a variable BASHVERS, from the contents of _distribution, and a variable BASHPATCH, from the contents of _patchlevel, (using m4 magic so we don't have to distribute .distribution and .patchlevel) and substitute them into Makefile.in Makefile.in - use Version and PatchLevel variables instead of the contents of .distribution and .patchlevel, respectively. These are set by configure - removed `.machine' from targets and dependencies support/mkversion.sh - new shell script to handle updating version.h, replaces mkversion.c (which is now overkill) support/mkdist - don't bother with writing .distribution and .patchlevel files, since they're no longer distributed support/mknewvers.sh - simple bash script to make new version files. It can increment the major or minor version numbers or patchlevel, or take a completely new version number (e.g., 2.01) as an argument doc/Makefile.in - added support for the `install-info' command to update the info directory file after installing bash.info 1/31 ---- builtins/help.def - fix core dump with `help --' susbt.c - make call_expand_word_internal obey the convention that if expand_word_internal returns &expand_word_{fatal,error}, then w->word has already been freed - return &expand_word_fatal from expand_word_internal if the shell is not interactive and `set -u' has been executed test.c, general.c - moved group_member from test.c to general.c externs.h, general.h - moved extern declaration of group_member from externs.h to general.h general.c - broke the code that initializes the group array out into a new function, initialize_group_array() - initialize_group_array() now initializes an array even if the OS does not have getgroups(). If it does not, an array with one element (the real gid) is created - call sysconf(_SC_NGROUPS_MAX) if sysconf is available and _SC_NGROUPS_MAX is defined - new function, char **get_group_list(int *), to return an array of strings made from the groups list variables.c - new dynamic array variable: GROUPS, expands to the group set as obtained with getgroups() (or whatever initialize_group_array() makes) doc/{bash.{1,html},bashref.texi} - added description of GROUPS variable test/test-tests - before modifying the setgid bit on /tmp/setgid, try to change its group to ${GROUPS[0]} 2/3 --- aclocal.m4 - new autconf macro, BASH_MISC_SPEED_T, to see if speed_t is defined in configure.in - call BASH_MISC_SPEED_T config.h.in - add `#undef SPEED_T_IN_SYS_TYPES' lib/readline/tcap.h - include `rltty.h' if HAVE_TERMCAP_H and __linux__ are defined, but SPEED_T_IN_SYS_STYPES is not, before including support/mksignames.c, siglist.c - add support for 4.4 BSD SIGLOST support/config.guess - add support for recognizing QNX based on `uname' output Makefile.in - make sure recho and zecho are compiled with the same set of CC options as the rest of the sources lib/readline/bind.c - change calls to rl_generic_bind to cast the third argument to (char *) where necessary command.h - two new flags: CMD_AMPERSAND (currently unused), and CMD_STDIN_REDIR, which means that this command should have its standard input redirected from /dev/null if there are not any explicit redirections to stdin execute_cmd.c - a redirection of type r_inputa_direction is no longer added at the beginning of the redirection chain for an async command; CMD_STDIN_REDIR is set in the flags instead - new function: stdin_redirects: returns the number of redirections to stdin in a chain of redirections - new functions: async_redirect_stdin() to open /dev/null and make it file descriptor 0 - changes to make CMD_STDIN_REDIR propagate to all of the necessary functions (like execute_simple_command) - execute_disk command now takes the flags from simple_command rather than just the CMD_NO_FORK flag as its last argument - various places after make_child is executed (in the child) check for CMD_STDIN_REDIRECT (and no stdin redirections or piping) and call async_redirect_stdin - stdin_redir is now global eval.c - set stdin_redir to 0 just before calling execute_command so it gets reset to a known value and doesn't persist across commands 2/4 --- builtins/ulimit.def - add a stub function for ulimit(2) on systems without HAVE_RESOURCE or HAVE_ULIMIT that just sets errno to EINVAL and returns -1 -- QNX is one such system bashhist.c - pre_process_line needs to protect all occurrences of hist_verify with #ifdef READLINE builtins/shopt.def - hist_verify needs to be protected with #ifdef READLINE, not #ifdef HISTORY 2/5 --- support/config.{guess,sub}, configure.in - chages to better support the Harris Night Hawk [many files] - changes for things pointed out by gcc -Wall lib/glob/Makefile.in - make sure -DSHELL is included in CCFLAGS so that globbing is interruptible lib/malloc/malloc.c - extern declaration for botch: if botch is #defined, it should be the name of a void function configure.in,Makefile.in,builtins/Makefile.in, lib/{glob,malloc,readline,tilde}/Makefile.in - add a LOCAL_DEFS variable, substituted from configure into the various Makefiles. It's set to -DSHELL, so that define gets passed to all sub-makes without doing anything special lib/readline/readline.c - change to rl_digit_loop to make it compatible with GNU emacs: if a key bound to `universal-argument' is read after reading some digits, it terminates the argument but is otherwise ignored. This is how people can insert repeated digits doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo - changed description of `universal-argument' to describe how to terminate a numeric argument 2/6 --- jobs.c - changed kill_pid to diddle the job and process data structures if we're sending SIGCONT to a stopped job with `kill' so that the shell knows the job is running again. ksh93 does this 2/7 --- unwind_prot.c - changed bcopy to FASTCOPY builtins/enable.def - changed pointer arithmetic in delete_builtin to just subtract the head of the builtins list (shell_builtins) from a pointer to the builtin to be deleted (b) to find its index in the list on ANSI C systems 2/10 ---- lib/readline/bind.c - when using old-style keynames to bind to a new-style macro, pass an array of type (unsigned char *) to rl_macro_bind builtins/getopt.c - change sh_getopt to return EOF if nextchar is empty or NULL and sh_optind is greater than argc. This can happen if a script mixes calls to `getopts' with calls to `shift' 2/11 ---- print_cmd.c - fixed make_command_string_internal so that commands with the CMD_TIME_POSIX flag set print `time -p' instead of `time' - changed print_redirection_list so the here documents are printed after all the other redirections, and followed by a newline (rather than a possible semicolon) - added a new variable, was_heredoc, to avoid adding a semicolon at the beginning of an empty line after printing the heredoc ending delimiter execute_cmd.c - don't put the gnu_argv_flags into the environment any more; it's proven to be a bad idea configure.in - set LOCAL_CFLAGS to `-DSunOS5' on Solaris 5.5[.x] builtins/echo.def - only call fflush() after printing each word on SunOS 5.5, since that's the system with the bug that prompted its inclusion in the first place support/mksignames.c - added support for more system-specific signals from AIX 4.2, changed initialization order so that system-specific signals are done first, before the common signals 2/12 ---- execute_cmd.c - broke the code that creates a file containing the text of a here document out into a separate function: here_doc_to_fd - create the temp file used for a here document with mode 600 - open the temp file used for a here document with O_EXCL shell.h - changed the uid members of struct user_info to be of type uid_t and the gid members to be of type gid_t parse.y - changed the type of the `type' argument to init_yy_io() to be `enum stream_type', since that's what's always passed input.h - changed the function prototype for init_yy_io so the third arg is type `enum stream_type' externs.h - added a prototype for getcwd, if HAVE_GETCWD is not defined builtins/umask.def - changed all variables that are used as arguments to or save the return value from umask(2) to be of type mode_t - changed print_symbolic_umask to take an argument of type mode_t 2/13 ---- jobs.c - if old_sigint_handler is set to SIG_DFL, as it will be in a script without a trap on SIGINT installed, call termination_unwind_protect() directly from waitchld() 2/14 ---- configure.in - added a section before the call to BASH_CHECK_LIB_TERMCAP to set a variable prefer_curses on some systems (AIX, for one) aclocal.m4 - in BASH_CHECK_LIB_TERMCAP, don't return -ltermcap if $prefer_curses is non-empty lib/readline/Makefile.in - redid the dependencies 2/17 ---- hashlib.c, getcwd.c - include `bashansi.h' instead of stdlib.h and string.h error.c, siglist.c, xmalloc.c, builtins/{common,evalfile,mkbuiltins,psize}.c, builtins/{exec,exit,fg_bg,hash,history}.def - include `bashtypes.h' instead of directly including builtins/fc.def - include ../bashtypes.h and ../posixstat.h instead of bashtypes.h and posixstat.h builtins/mkbuiltins.c - include ../posixstat.h instead of general.h - include `bashtypes.h' if RLIMTYPE is defined, so we can fetch a definition of quad_t (or whatever) from before using it in a function prototype Makefile.in, builtins/Makefile.in - updated dependencies 2/18 ---- builtins/set.def - new function, set_posix_mode, called when `set [-+]o posix' or `shopt -[su] -o posix' is executed. It sets or unsets $POSIXLY_CORRECT and calls sv_strict_posix subst.c - in sv_strict_posix, call posix_readline_initialize only if the shell is interactive (interactive_shell != 0) shell.c - if we are acting like `sh', call posix_readline_initialize if the shell is interactive - moved the code that does posix.2 mode initialization after interactive_shell is set, and call posix_readline_initialize if interactive_shell is non-zero bashwait.h - renamed to unionwait.h, since that is what it defines posixwait.h - moved the POSIX 1003.1 job control defines here from jobs.h jobs.h - include `posixwait.h' 2/19 ---- braces.c - if SHELL is defined, pass the contents of new-style command substitution through without expanding brace constructs between the parens -- let the subshell do it subst.c - when brace-expanding words, preserve the flags (word->flags) if brace expansion does not change the word. This fixes the problem of things like local -a avar=( ${PATH//: } ); bashline.c - have shell_expand_line pass a copy of rl_line_buffer to expand_string in case there are substitution errors and the string gets freed 2/20 ---- expr.c - make sure that expland and explor set `lasttok' to LAND and LOR, respectively, if they parse `&&' or `||'. This makes the precedence code work right subst.c - changes so that non-interactive shells exit immediately when a parameter that is unset is referenced after `set -u' has been executed causes the shell to exit immediately 2/21 ---- flags.c - if `set -r' is executed, call maybe_make_restricted so that $PATH and $SHELL are made read-only execute_cmd.c - if `set -e' has been executed, and we're inverting a pipeline's return status with `!', set CMD_IGNORE_RETURN so a failing command does not inadvertently cause the shell to exit before the exit status can be inverted. This is probably only a problem with the `eval' builtin. 2/24 ---- builtins/hash.def - add a missing argument of 0 to add_hashed_command builtins/kill.def - job identifiers can be used in non-interactive shells as long as job control has been turned on with `set -m' jobs.c - we want to be notified of stopped jobs if job_control is non-zero, even if the shell is not interactive execute_cmd.c - make sure shell_execve returns EX_NOTFOUND if execve fails and errno is set to ENOENT - makes sure execute_builtin saves the temporary environment to builtin_env for the `eval' builtin, since it can destroy the temporary environment when it calls parse_and_execute bashhist.c - new variable: hist_last_line_added, set to 1 if the last command line was added to the history successfully as a separate entry. Used by `history' and `fc' 2/25 ---- trap.c - save line number before executing trap command, because parse_and_execute resets it to 1 and the trap command might want it execute_cmd.c - change to executing_line_number to return trap_line_number if the shell is currently running a trap 2/26 ---- execute_cmd.c - change to time_command so that a `real' value of 0 does not cause a divide-by-zero error when computing cpu percentage lib/readline/signals.c - if MUST_REINSTALL_SIGHANDLERS is defined, reinstall the SIGWINCH handler in rl_handle_sigwinch builtins/set.def - `unset' now rejects attempts to unset names that are not valid shell identifiers as errors - add a description of `-o history' option to help text subst.c - in parameter_brace_patsub, we want backslash removal done on the replacement if (mflags & MATCH_QUOTED), since the code in expand_word_internal will not do it. We need to call expand_string_unsplit directly, since maybe_expand_string does not do the right thing 2/28 ---- execute_cmd.c - if execute_for_command finds that the iteration variable is readonly, decrement loop_level before returning builtins/break.def - if the break count is <= 0, display an error message and break out of all loops builtins/command.def - if PATH is unset, and we're using command -p, we don't want PATH to be set to the empty string when `command' completes builtins/common.c - POSIX.2 says `kill -l signum' prints the signal name without the leading `SIG' prefix, so check for this_shell_builtin == kill_builtin in display_signal_list builtins/getopts.def - when invoked without any arguments, `getopts' now prints a usage message 3/3 --- builtins/common.c - add a second argument to get_numeric_arg: if non-zero, the shell exits on a bad argument; if not, the shell jumps to top_level with a DISCARD argument, which aborts the current command builtins/{break,exit,history,return,shift}.def - change calls to get_numeric_argument lib/readline/funmap.c - add `dump-macros' to list of bindable names lib/readline/readline.h - added extern declaration for rl_prompt (it was apparently missing) lib/readline/readline.c - new internal function, _rl_init_line_state, which sets rl_point and rl_end to 0, sets the_line to point to _rl_line_buffer, and clears the line lib/readline/callback.c - if a user's callback function does not clear the line, clear it for him by calling _rl_init_line_state 3/4 --- alias.c - made the readline support functions #ifdef READLINE, so they're not compiled into the shell unless readline is lib/readline/bind.c - new function _rl_untranslate_macro_value, to expand meta-prefixes and other special characters in a macro value for printing by _rl_macro_dumper_internal - call _rl_untranslate_macro_value in _rl_macro_dumper_internal to get a printable version of the macro value lib/readline/readline.c - new variable, rl_dispatching, set to 1 when we call a function from _rl_dispatch lib/readline/readline.h - extern declaration for rl_dispatching lib/readline/complete.c - make sure S_ISCHR and S_ISBLK are defined before using them lib/readline/terminal.c - add a new #define NEED_EXTERN_PC. Define this if the termcap or curses libraries need `extern' before declarations of PC, BC, and UP lib/readline/{readline,terminal,histfile}.c - changes to compile on OS/2 with OS/2 `EMX' port of gcc, originally sent by ilya@math.ohio-state.edu builtins/set.def - fixed a bug in set_shellopts that caused the shell to crash if there were no shell options set 3/5 --- configure.in,Makefile.in - choose run-all or run-minimal as the test script based on whether the --enable-minimal-config option was given to configure builtins/setattr.def - fixed `export -p' and `readonly -p' so that they output `export' or `readonly' when in POSIX mode, as POSIX.2 specifies 3/6 --- builtins/setattr.def - make `readonly -a var=(...)' work just like `declare -ar var=(...)', since the two logically mean the same - `readonly -f' and `export -f' don't print the function definition for each readonly or exported function, respectively, when in POSIX mode jobs.c, nojobs.c - don't report status for processes killed by SIGPIPE if DONT_REPORT_SIGPIPE is defined config.h.top - added a commented-out define for DONT_REPORT_SIGPIPE execute_cmd.c - `time' can now be used to time background pipelines, and reports the timing statistics when the pipeline completes [bash-2.01-alpha1 frozen] 3/12 ---- subst.c - move the parent end of the pipe file descriptor used for process substitution to a high, unused file descriptor to avoid clashes with redirections performed explicitly by a script configure.in - added a `--with-curses' argument so curses can be forcibly chosen over libtermcap (some Unix versions ship lousy termcap databases) support/mkconffiles - new script to create _distribution and _patchlevel from values contained in `configure' doc/bashref.texi - updated installation instructions 3/13 ---- general.c - if `getgroups' returns 0, make sure we add the primary group id as GROUPS[0]. - if we have getgroups, and the primary gid is not in the array getgroups returns, add it as group_array[0] and shuffle everything up one element. This ensures that current_user.gid == group_array[0] all the time tests/builtins.tests - changes to avoid stray variables in environment when the shell version of printenv is used with bash as /bin/sh, running the `exec -c' tests. 3/14 ---- builtins/cd.def - spelling correction is no longer enabled by default support/bashbug.sh - if the shell's release status is alpha or beta, offer the option of sending the bug report to the bash-testers mailing list as well as to chet 3/17 ---- configure.in - configure --without-gnu-malloc by default on *-sgi-irix6* because their code needs 8-byte alignment support/bashbug.sh - ``' needs to be quoted with a backslash in double-quoted strings aclocal.m4 - slight changes to the strcoll test, since AIX 4.2 returns -1, 0, or 1 from strcmp(3) but a numeric collation order difference from strcoll(3) 3/18 ---- command.h - new redirection error code: HEREDOC_REDIRECT execute_cmd.c - return HEREDOC_REDIRECT from do_redirection_internal when here_document_to_fd cannot create the temp file for a here document - changed redirection_error to print a meaningful message when here document temp file creation fails (HEREDOC_REDIRECT) 3/19 ---- subst.c - changes to match_pattern_char: return 1 if the first char of the pattern is `?' only if the string is non-null; just return 1 if the first char of the pattern is `[' and the string is non-empty rather than try to re-implement the brace matching code from fnmatch lib/glob/fnmatch.c - some changes from glibc-2.0.1 posix/fnmatch.c 3/21 ---- variables.c - only do the initialization of `ignoreeof' if the shell is interactive - reset values of $SHLVL > 1000 to 1 in adjust_shell_level, and don't call itos, since we don't need its generality - new function, initialize_shell_level, just calls adjust_shell_level with argument of 1. If $SHLVL is unset, adjust_shell_level will deal with it correctly - change initialize_shell_variables to not malloc a copy of each environment variable, just keep two pointers into the env string: one for the name, one for the value - broke the code that computes the value of $BASH out into a separate function: get_bash_name - get_bash_name special-cases shell_name with a `./' prefix when initializing $BASH - new function: set_home_var, sets $HOME to current_user.home_dir if it's not already set, calling get_current_user_info if current_user.home_dir is NULL - new function: set_shell_var, sets $SHELL to current_user.shell if it's not already set, calling get_current_user_info if current_user.shell is NULL - changed places that reference information in current_user to check for NULL values of the member they're interested in and call get_current_user_info if necessary shell.c - moved the code that sets up the information in current_user that comes from the password file into a new function, get_current_user_info - shell_initialize calls get_current_user_info only if the shell is interactive externs.h - new extern declaration for get_current_user_info(), so variables.c can use it 3/24 ---- lib/tilde/tilde.c - if SHELL is defined, user the current_user struct info to find the user's home directory rather than calling getpwuid 3/25 ---- nojobs.c - don't try to open /dev/tty when getting or setting the tty state and window size; use shell_tty instead - initialize shell_tty to standard error in initialize_job_control - only fetch the tty state initially if the shell is interactive general.c - open /dev/tty with the O_NONBLOCK flag variables.c - changed all_vars so that it sorts its output all the time, not just when in POSIX mode. This means that the output of `set' and `export' will be sorted builtins/set.def - in initialize_shell_options, only call parse_shellopts if we inherited $SHELLOPTS from the environment - make sure we call parse_shellopts from initialize_shell_options with a copy of the value of SHELLOPTS, in case one of the functions called while setting one of the variables modifies $SHELLOPTS lib/readline/readline.c - make sure that digit arguments don't change the state of rl_last_func support/printenv.c - new file, printenv(1) clone, used to avoid environment variables that might be set automatically when using printenv.sh lib/tilde/tilde.c - if SHELL is defined, don't call getenv to get the value of $HOME, call get_string_value () directly 3/26 ---- lib/readline/histexpand.c - abstracted the `#ifdef SHELL' stuff that checked for special cases that should not be history expanded ([!...], ${!...}) into a call to a function that is the value of the new history_inhibit_expansion_function variable lib/readline/history.h - extern declaration for history_inhibit_expansion_function bashhist.c - new function, bash_history_inhibit_expansion, which checks for the special cases in which history expansion should be inhibited - changes to the various history initialization functions to set history_inhibit_expansion_function lib/readline/doc/hstech.texinfo - documented history_inhibit_expansion_function lib/readline/shell.c - new file, containing versions of the functions that are provided by bash when readline is linked as part of bash - new function: get_env_value(). If SHELL is defined, this calls get_string_value(). If SHELL is not defined, this calls getenv() lib/readline/histexpand.c - moved single_quote() to shell.c lib/readline/util.c - moved savestring() to shell.c lib/readline/terminal.c - moved set_lines_and_columns() to shell.c lib/readline/Makefile.in, Makefile.in - added shell.c and shell.o to the appropriate variables that contain the files comprising the readline and history libraries lib/readline/signals.c - introduced two new cpp defines: HANDLE_JOB_SIGNALS and HANDLE_SIGTERM. When HANDLE_JOB_SIGNALS is defined, SIGTSTP, SIGTTIN, and SIGTTOU are caught and handled. When HANDLE_SIGTERM is defined, SIGTERM is caught and handled. These are both defined automatically if SHELL is not defined lib/readline/{bind,histfile,nls,readline,terminal}.c - call get_env_value instead of getenv(). This should remove the dependency on being able to redefine getenv() in oslib.c shell.c - added a missing argument of -1 to the call to list_minus_o_opts. Now `bash -o' lists all options, not just random ones depending on what's on the stack 3/28 ---- builtins/ulimit.def - change RLIM_INFINITY to the hard limit only if the hard limit is greater than the current (soft) limit hashlib.c - return immediately from flush_hash_table if the hash table passed is NULL 4/1 --- shell.c - remove call to initialize_filename_hashing -- initialize the hash table the first time a hashed command has to be remembered hashcmd.c - new file, with functions to perform filename hashing and lookup taken from builtins/hash.def and builtins/common.c - change to remember_filename -- call initialize_filename_hashing if hashing_initialized is 0 hashcmd.h - new file, mostly from builtins/hashcom.h, with extern function declarations added execute_cmd.c, builtins/{hash,type}.def - include hashcmd.h for hash function and type definitions builtins/{common.{c,h},hash.def} - moved hashing functions and declarations to hashcmd.c/hashcmd.h Makefile.in, builtins/Makefile.in - changed source and object file definitions and dependencies because of addition of hashcmd.h and hashcmd.c builtins/hash.def - return immediately from print_hashed_commands if hashed_commands is empty, indicating that the hash table has not been initialized 4/2 --- lib/readline/bind.c - fixed translation of ESC in rl_untranslate_keyseq and rl_untranslate_macro_value lib/readline/{readline,kill}.c - added an argument to _rl_fix_point telling it whether or not to fix up the mark also; changed calls to _rl_fix_point to add the appropriate argument Makefile.in - changed the substitution delimiter in the `sed' commands that create bashbug from `:' to `%' to avoid conflicts with options containing `:' 4/3 --- print_cmd.c - made the initial value and the default growth value for the printed command somewhat smaller -- we don't really need to allocate 4096 bytes for the printed command - added stdarg support to xprintf if PREFER_STDARG is defined stringlib.c - changed strip_trailing to take the index of the last character as the second argument, saving a (useless) call to strlen, since the caller already knows where the end of the string is subst.c - change call to strip_trailing in command_substitute to add the new second argument externs.h - changed extern declaration for strip_trailing 4/4 --- Makefile.in, configure.in, lib/malloc/Makefile.in - changed the strategy for picking which `malloc' to include by having configure define a `malloc target' and the Makefile in lib/malloc implementing rules for that target 4/5 --- Makefile.in - slightly changed the rules for remaking `parser-built': it is now a copy of y.tab.h, updated only when the contents of y.tab.h change - everything that used to depend on y.tab.h now depends on parser-built 4/6 --- execute_cmd.c, print_cmd.c - use #include so we pick up y.tab.h from the build directory instead of the source directory if it happens to be recreated in the build directory 4/7 --- bashline.c - fixed another problem with `pwd`/[TAB] thinking that the `/ started an unclosed command substitution, generating errors 4/8 --- general.c - renamed bash_tilde_expansion_failure_hook to be bash_special_tilde_expansions, since that more accurately reflects its function - changed tilde_initialize so that there is no failure hook -- the special expansions are handled first with the preexpansion hook lib/tilde/tilde.c - new variable: tilde_expansion_preexpansion_hook -- if non-null, it points to a function that is called before standard tilde expansion is attempted lib/tilde/tilde.h - extern declaration for tilde_expansion_preexpansion_hook doc/{bash.{1,html},bashref.texi} - added optional open paren to description of `case' command syntax 4/9 --- variables.c - on qnx, set and export a variable `NODE' which contains the QNX `node id' general.c - QNX system can now handle pathnames with a leading `//' configure.in - added `-Dqnx' to LOCAL_CFLAGS on QNX machines lib/malloc/getpagesize.h - some systems need sysconf(_SC_PAGE_SIZE) to obtain the page size; added code to check for it 4/10 ---- print_cmd.c - include the prototype for cprintf only if PREFER_STDARG is defined, otherwise just have a K&R-style forward function declaration hashlib.h - reduced the default number of buckets in a hash table to 53 lib/tilde/tilde.c - prime the result string in tilde_expand by allocating a new string that's as long as the input string (+16 if a tilde appears in the string to be expanded). This should reduce the number of reallocs subst.c - broke the code that reads the output of a command substitution through the pipe to the subshell out into a separate function: read_comsub(). This does not use stdio, but rather reads directly from the pipe into a local 128-character buffer 4/11 ---- execute_cmd.c - some systems need both and , so include both if it's possible, otherwise include (if present) lib/readline/rl{tty,defs}.h - moved includes of , , etc. to rltty.h lib/readline/terminal.c - include rltty.h after rldefs.h variables.c - changes to make environment creation faster and use less memory (fewer malloc/free calls, too): o two new variables: export_env_index (how many environment strings are in export_env) and export_env_size (the number of slots for strings allocated in export_env) o added new function add_to_export_env, since adding the exported shell variables and shell functions does not need to search the export_env for a definition to supersede (we just cleared it out!) o renamed add_or_supersede to add_or_supersede_exported_var, since it always works on export_env, and changed the second argument to a flag saying whether or not to allocate a new copy of the string placed into the environment o changed calls to add_or_supersede to the new add_or_supersede_exported_var with the appropriate flags o don't free and reallocate export_env in maybe_make_export_env, just free the strings and start anew o prime the size of export_env from the total number of shell variables and shell functions -- this will always be enough for the exported shell functions and variables, and big enough most of the time for the entire environment builtins/cd.def - efficiency hack in bindpwd(): if PWD is exported, we will have to rebuild the entire exported environment after every time we change directories. What we do is see if array_needs_making changes value from 0 to 1 after bind_variable ("PWD", dirname) is called, and that PWD is exported. If that happens, we just replace the value of PWD in the exported environment with a call to add_or_supersede_exported_var bashline.c, parse.y - check calls to pre_process_line to make a fresh copy of the line if pre_process_line returns what it was passed, in preparation for future changes bashhist.c - pre_process_line now returns its argument if it did not make any changes to it alias.c - free the bucket entry holding the alias to be removed in remove_alias, as well as the data 4/14 ---- unwind_prot.c - if an unwind-protect frame is being discarded, and its cleanup function is `restore_variable', the `arg' member points to a SAVED_VAR that must be freed. This change is made in remove_unwind_protect_internal and unwind_frame_discard_internal parse.y - need to free memory allocated by parse_arith_cmd if it is an arithmetic command, after using it to make a new word subst.c - fixed some memory leaks caused by not freeing the argument to make_bare_word, which duplicates its string argument - need to dispose list generated by list_rest_of_args in paramter_list_remove_pattern - make sure the return value from getpattern() is freed - make sure array_value_internal always returns newly-allocated memory - get_var_and_type returns a new type: VT_ARRAYMEMBER if the string passed is of the form var[index] - make sure parameter_brace_substring frees the memory allocated by get_var_and_type if verify_substring_values returns 0 hashlib.c, hashlib.h - new function, dispose_hash_table (table), which frees the table's bucket array and the table itself alias.c - call dispose_hash_table from delete_all_aliases instead of just freeing the table pathexp.c - make sure to free `newnames' (but *not* its contents) before returning from ignore_globbed_names builtins/exec.def - make sure the argv created to pass to shell_execve is freed if the execve fails and we're not exiting on failed execs expr.c - broke evalexp into two functions: evalexp, which sets up the jmp_buf that errors jump to, and subexpr, which does the evaluation and pushing and popping of contexts - readtok now calls subexpr to evaluate subexpressions in parentheses - evalexp now takes an additional paramter, a pointer to an int. If the expression contains errors, the location to which this points gets 0, otherwise it gets 1 to show that the value returned may be used. This plugs up memory leaks that were the result of evalexp() longjmping back to top_level - fixed a memory leak: expr_stack[0] was not being freed externs.h - changed extern declaration for evalexp variables.c, subst.c, builtins/let.def - changed calls to evalexp appropriately. They either cause a longjmp (top_level, DISCARD) (which is what the old stuff in expr.c did) or are handled by returning an appropriate error value (e.g., &expand_word_error in subst.c) 4/16 ---- shell.c - make sure to free dollar_vars[0] before assigning it the first argument following `-c command' variables.c - if unsetting a local variable with a previous context, make sure to free the hash table element used to store the local variable lib/readline/terminal.c - rearrange the includes so is included before rltty.h, as it is in rltty.c 4/17 ---- flags.c - new function: reset_shell_flags, which resets all of the flags back to their initial values flags.h - extern declaration for reset_shell_flags builtins/set.def - new function: reset_shell_options, which resets all of the -o options that are not also shell flags back to their initial values builtins/shopt.def - new function: reset_shopt_options, which resets all of the shopt options that are not also shell flags or -o options back to their initial values builtins/common.h - extern declarations for reset_shell_options and reset_shopt_options execute_cmd.c - broke the code that reinitializes things when an executable script without a leading `#!' is found out into a new function: initialize_subshell - initialize_subshell now calls the reset_* functions that reset the shell flags and options general.c, general.h - move_to_high_fd now takes a third argument: the highest fd at which to start looking. If that's less than 20, the maximum number of open files as returned by getdtablesize() is used (which is what it did before this) jobs.c, shell.c, subst.c - changed calls to move_to_high_fd appropriately [bash-2.01-beta1 frozen] 4/18 ---- general.c - itos now uses a local char buffer to do its conversion, but still returns newly-allocated memory 4/21 ---- variables.c - be a little more careful when checking for backwards-compatibility with exported function definitions 4/22 ---- builtins/ulimit.def - translate RLIM_INFINITY to limit.rlim_max if the current limit is less than or equal to the hard limit, not just strictly less than (the change of 3/28 was too drastic) 4/23 ---- oslib.c - fixed definition of to_lower on machines without strcasecmp trap.c - don't free the trap command in change_signal if the SIG_INPROGRESS is set in the signal's flags -- it will cause memory to be freed twice if a trap command resets the signal handler more than once, and _run_trap_internal keeps a pointer to the trap command so it can free it, so there will be no leaks 4/24 ---- aclocal.m4,configure.in - removed BASH_CC_WORKS, since AC_PROG_CC now has the functionality shell.c, externs.h - get_current_user_info is now a void function bashline.c - alias_expand_line_internal was removed - new function, alias_expand_line, performs alias expansion on rl_line_buffer and either replaces rl_line_buffer or signals an error - new bindable commands: alias-expand-line and history-and-alias-expand-line, available if ALIAS is defined 4/25 ---- Makefile.in, lib/malloc/malloc.c - changed the define that turns on malloc range checking from `rcheck' to `RCHECK' lib/readline/isearch.c - fixed a couple of places where rl_search_history would try to free a NULL pointer 4/29 ---- unwind_prot.c - fixed a problem with saving a variable that is a null pointer in unwind_protect_var. It happens only on machines where the size of a pointer is not the size of an int. The old FASTCOPY code would copy the eight bytes at memory location zero, which did not necessarily make a null pointer 4/30 ---- shell.c - run_startup_files should turn off job control, since the startup files should be run without job control enabled -- this makes SIGINT interrupt startup file execution again - if we get a SIGINT or other longjmp to top_level while executing the startup files, re-enable job control for interactive shells before setting locally_skip_execution 5/2 --- lib/readline/nls.c - if we have setlocale(3), don't bother with checking the environment variables for valid values; just use setlocale() to set the locale categories from the environment variables directly and go into eight-bit mode if the current locale is not C or POSIX 5/5 --- sig.c - make sure that the handler for SIGPROF is not changed if it has been set to something other than SIG_IGN or SIG_DFL -- this makes profiling work after the terminating signals have been initialized bashline.c - if a filename containing `!' is completed, and the user has started the string with a `"', change the completion style to backslash- quoting, since there's no way to use `!' with double quotes (this requires more changes to readline to really work right) 5/6 --- lib/readline/complete.c - changes to make_quoted_replacement, insert_all_matches, and insert_match and their callers to allow the application-specific filename quoting function to change the quote character (e.g., for bash to change a filename containing a `!' and started with a double quote by the user into a filename with the `!' quoted by a backslas and no double quote) 5/8 --- jobs.c - new function: nohup_all_jobs(), calls nohup_job for each entry in the jobs list - delete_all_jobs is now global jobs.h - new extern declarations for delete_all_jobs() and nohup_all_jobs() builtins/jobs.def - `disown' without any jobspec arguments means the current job. Fix a core dump printing the error message when there is no current job 5/12 ---- subst.c - process an expansion like $((foo); bar) as a command substitution, not as an arithmetic expansion. An arithmetic expansion must have a closing `))' 5/14 ---- builtins/evalstring.c - the third argument to parse_and_execute() is now a flags word. The caller can control the value of `interactive' and whether or not history is disabled while parse_and_execute() runs builtins/common.h - new #defines for the flag values for parse_and_execute() {bashline,jobs,shell,subst,trap,variables}.c, parse.y, builtins/evalfile.c, builtins/{eval,fc}.def - changed calls to parse_and_execute appropriately builtins/evalfile.c - if _evalfile() is passed FEVAL_HISTORY as part of the flags arg, don't pass SEVAL_NOHIST to parse_and_execute - new function: fc_execute_file, which sets FEVAL_HISTORY in the flags argument to _evalfile() bashline.c - call bash_add_history instead of add_history from vi_edit_and_execute_command so the bash state variables get updated properly. This keeps the `v' command from operating on an empty command when the history list is stifled bashhist.c - bash_add_history is now global bashhist.h - extern declaration for bash_add_history builtins/fc.def - call fc_execute_file instead of maybe_execute_file in the edit-and-re-execute case (fc -e ...) - don't manually insert the commands from the file created by `fc -e' into the history list, just set remember_on_history and let fc_execute_file take care of telling parse_and_execute to do the right thing. This makes compound commands and the `cmdhist' and `lithist' settings work better. This supersedes the fix of 1/27. This was reported again by rchen@fractal.eng.yale.edu. parse.y - the body of a `for' command (the commands between do...done or {...}) should be a `compound_list' instead of a `list'. Problem reported by cpg@research.bell-labs.com 5/19 ---- lib/readline/complete.c - in filename_completion_function, if we find that the directory pointer (return value from opendir(3)), is not null when state is 0 (indicating that this is the first time the completion function has been called for the current completion), call closedir on it, assuming that it was left open by a previous (interrupted) completion [bash-2.01-beta2 frozen] 5/27 ---- Makefile.in - make sure that `make distclean' (and other clean targets) remove the `printenv' executable tests/execscript, tests/redir.tests - make sure to set LANG=C and LC_ALL=C so the messages show up in English tests/run-func - add a warning about exported functions in the environment 5/29 ---- builtins/hash.def - if one of the arguments passed to `hash' is an absolute pathname, just continue the loop, don't do list=list->next first. This fixes the `hash a/b' -> core dump bug 5/30 ---- general.c - change canonicalize_pathname to leave a leading `/' alone, as POSIX requires 6/2 --- support/xenix-link.sh - shell script for linking bash under Xenix 6/3 --- bashline.c - fixed a memory leak in command_word_completion_function, courtesy of a.pfaller@pop.gun.de hashcmd.c - fixed find_hashed_filename to always return a newly-allocated string execute_cmd.c - since find_hashed_filename returns newly-allocated memory, don't call savestring() on it, and free it if the data is stale (in search_for_command()). Another memory leak fixed courtesy of a.pfaller@pop.gun.de builtins/type.def - free the value returned by find_hashed_filename [bash-2.01-release frozen] 6/6 --- configure.in - force shlicc2 and libc malloc for BSD/OS 3.0 6/9 --- doc/Makefile.in - don't create ${man3dir}, since we're not installing the readline manual page lib/readline/readline.h - rl_dispatching should be declared `extern' [in bash-2.01.1] 6/10 ---- lib/malloc/Makefile.in - make sure ${ALLOCA_SOURCE} is preceded by ${srcdir} so that things work when building in a directory other than the source directory [in bash-2.01.1] 6/30 ---- lib/readline/examples/rltest.c - don't free the value returned by history_list() lib/readline/histfile.c - open the history file for writing with mode 0600 for better security [in bash-2.01.1] execute_cmd.c - select_query now uses legal_number to decide whether the user's selection is a valid number, and just executes the loop again if invalid input is entered [in bash-2.01.1] 7/1 --- builtins/evalstring.c - fix to parse_and_execute so `bash -c 'time [-p] zzz'' works right [in bash-2.01.1] execute_cmd.c - fix to execute_command_internal so that `bash -c time [-p] (zzz)'' works right [in bash-2.01.1] - print_formatted_time should pass a long as the fourth parameter to mkfmt [in bash-2.01.1] externs.h, shell.c - `exit_shell' is now a void function hashlib.c - print_table_stats is now a void function mailcheck.c - made add_mail_file check for the filename in the mail file list using the expanded filename, since that is what it puts into the list [in bash-2.01.1] variables.c - for the time being, PWD will be auto-exported, since some systems seem to expect it doc/bashref.texi, lib/readline/doc/{hist,rlman}.texinfo - added necessary `dircategory' and `direntry' commands to make `install-info' work correctly Makefile.in - move $(LDFLAGS) after $(BUILTINS_LDFLAGS) and $(LIBRARY_LDFLAGS) on the line that links bash doc/texinfo.tex - upgraded to version 2.185 from the texinfo-3.9 distribution lib/tilde/tilde.c - fixed a bug in tilde_expand so that enough space is allocated for the string and terminating null byte if a `~' does not appear. This was masked before by the bash malloc() [in bash-2.01.1] 7/3 --- aclocal.m4 - new test, BASH_TYPE_INT32_T, to check which builtin C type is 32 bits wide - new test, BASH_TYPE_PTRDIFF_T, to check which builtin C type is appropriate for pointer arithmetic configure.in - check sizes of int and long, and for the existence of an int32_t basic system type. Call BASH_TYPE_INT32_T if int32_t is not defined anywhere in the system header files - check size of (char *), and for the existence of a ptrdiff_t basic system type. Call BASH_TYPE_PTRDIFF_T if ptrdiff_t is not defined anywhere in the system header files - added a check for config.h.in - add lines for SIZEOF_INT, SIZEOF_LONG, SIZEOF_CHAR_P, int32_t, u_int32_t, and ptrdiff_t - added line for HAVE_STDDEF_H lib/malloc/malloc.c - new version, with many changes and much better memory usage; old (bash-2.01) version is lib/malloc/omalloc.c lib/malloc/gmalloc.c - new version, with a number of changes and range checking included by default; old (bash-2.01) version is lib/malloc/ogmalloc.c execute_cmd.c - applied patch from 5/27 to make execute_simple_command fork early if it's part of a pipeline. This keeps assignment statements or other commands that don't require a builtin, function, or disk command to be executed from modifying the shell's environment tests/exec?.sub - renamed from tests/execscript.sub? because those filenames are too long for System V 14-char filename systems tests/source?.sub - renamed from tests/source.sub? because those filenames are bad for DOS/Windows tests/getopts?.sub - renamed from tests/getopts.sub? because those filenames are bad for DOS/Windows tests/histexp.{tests,right} - renamed from histexpand.{tests,right} because those filenames are too long for System V 14-char filename systems tests/trap1.sub - renamed from trap.sub1 because that filename was bad for DOS/Windows tests/ifs-[123].right - renamed from ifs.[123].right because those filenames were bad for DOS/Windows tests/ifs-[123].test - renamed from ifs-test-[123].sh because those filenames were bad for DOS/Windows examples/startup-files/Bashrc.bfox - renamed from examples/startup-files/Bashrc because that filename conflicts with examples/startup-files/bashrc on case-insensitive file systems tests/exec.right - renamed from execscript.right because that filename is too long for System V 14-char filename systems tests/run-set-e - renamed from run-set-e-test tests/misc/perftest - renamed from tests/misc/haertel.perftest because that filename is too long for System V 14-char filename systems lib/glob/fnmatch.c - new version with full POSIX.2 BRE matching (character classes, collating symbols, equivalence classes), full support for strcoll(3), and case-insensitive pattern matching lib/glob/fnmatch.h - new version, with necessary symbols for the new fnmatch.c tests/posixpat.{tests,right}, tests/run-posixpat - test suite for the POSIX.2 BRE pattern matching code variables.c - make sure that array assignment using the compound syntax empties the array before doing the assignment [in bash-2.01.1] trap.c - new function, trap_to_sighandler(sig), which returns the correct trap handler for SIG depending on the information in sigmodes[sig] [in bash-2.01.1] sig.h - extern declarations for trap_handler and trap_to_sighandler [in bash-2.01.1] jobs.c - if we get an interrupt while waiting for a command to complete, and there was a trap set on SIGINT that resets the handler to SIG_DFL, the value that waitchld uses for old_trap_handler will be wrong (it will be trap_handler, but trap_handler no longer knows anything about SIGINT). If old_signal_handler is trap_handler, but signal_is_trapped(SIGINT) returns 0, we need to call trap_to_sighandler to decide what to do [in bash-2.01.1] 7/7 --- locale.c - fix to set_locale_var to handle an assignment to LC_ALL (e.g., as the result of `unset LANG') when default_locale is null [in bash-2.01.1] 7/8 --- builtins/umask.def, doc/{bash.{1,html},bashref.texi} - added `-p' option for umask to print output in a reusable form 7/9 --- doc/{bash.{1,html},bashref.texi} - removed descriptions of `-type', `-path', and `-all' options to the `type' builtin in preparation for removing them in the next release builtins/type.def - removed mention of `-type', `-path', and `-all' options from the long help description error.c, error.h - new function: internal_warning, for warning messages variables.c - changed a call to internal_error to use internal_warning - modified change of 7/3 so that arrays are not emptied until just before the shell is about to assign the new values, so the old value can be used to generate the rhs of the assignment, if necessary. This is how `normal' shell variables work [in bash-2.01.1] jobs.c, jobs.h - delete_job now takes a second int argument and prints a warning message when deleting a stopped job if the second argument is non-zero jobs.c, builtins/jobs.def - changed all calls to delete_job to provide a proper second arg lib/readline/bind.c - broke rl_read_init_file into an `upper' and `lower' half in preparation for adding file inclusion capability to inputrc parsing - handle_parser_directive now displays an error message if an unknown directive is encountered - parser_endif now prints an error message if an $endif without a matching $if is found - added `$include' parser directive to read bindings and commands from another file at that point lib/readline/doc/rluser.texinfo, doc/{bash.{1,html},readline.3} - documented new readline `$include' parser directive shell.c, parse.y - added a new invocation option, --dump-po-strings, and code to make it dump translatable strings ($"...") in GNU gettext `po' format doc/{bash.{1,html},bashref.texi} - documented new `--dump-po-strings' invocation option lib/readline/{{kill,funmap}.c,readline.h} - added `rl_paste_from_clipboard()', bound to `paste-from-clipboard' for CYGWIN32 users lib/readline/kill.c - incorporated bfox's patches for `iterative' yank-last-arg handling. This means that one can keep pressing M-. and move backwards in the history, yanking the last argument of successive history lines lib/readline/rlwinsize.h - new file, encapsulates various locations of the definition for `struct winsize' aclocal.m4 - augmented BASH_STRUCT_WINSIZE to look in termios.h as well as sys/ioctl.h for definition of `struct winsize' lib/readline/rltty.h - include "rlwinsize.h" after including tty-driver-specific header file 7/10 ---- support/config.guess - add better support for SunOS on M68K (old Sun3 machines) parse.y - check for compound array assignment in read_token_word only if there are characters before the `=' (which would make it a legal assignment statement). This fixes the problem with defining a function named `=' with `=() { echo foo; }' [in bash-2.01.1] jobs.c, jobs.h - nohup_all_jobs and delete_all_jobs now take a parameter which says whether or not to restrict their operation to only running jobs jobs.c - changed all calls to delete_all_jobs builtins/jobs.def - added `-a' (all jobs) and `-r' (running jobs only) options to `disown' doc/{bash.{1,html},bashref.texi} - documented new `-a' and `-r' options to `disown' findcmd.c, findcmd.h - new files with command searching code from execute_cmd.c and function declarations from execute_cmd.h Makefile.in, builtins/Makefile.in - updated dependencies to account for new findcmd.[ch] - updated dependencies to account for new redir.[ch] redir.c, redir.h - new files with code that sets up lists and performs redirections from execute_cmd.c and execute_cmd.h execute_cmd.c - include new findcmd.h, redir.h 7/11 ---- Makefile.in, configure.in - PROFILE_FLAGS is now substituted into the Makefile by configure 7/14 ---- print_cmd.c - make sure single_quote is called from xtrace_print_word_list to correctly quote each word of trace output, especially those with embedded quotes [in bash-2.01.1] aclocal.m4 - extended BASH_CHECK_GETPW_FUNCS so that it checks that getpwuid and getpwnam can also be declared, as well as getpwent [in bash-2.01.1] - in BASH_FUNC_PRINTF, cast printf to type `_bashfunc' before trying to assign it to `pf' to avoid any prototype problems in the declaration [in bash-2.01.1] trap.c - include before any of the bash-specific header files, but after config.h [in bash-2.01.1] test.c - include and declare `extern int errno' before including any of the bash-specific include files, but after [in bash-2.01.1] builtins/Makefile.in - PROFILE_FLAGS is now substituted into the Makefile by configure configure.in - new options, --enable-profiling and --enable-static-link, to turn on profiling with gprof and link bash statically (if using gcc) for use as a root shell. The former implies the latter. If we're linking statically, dynamic loading of new builtins is not available doc/bashref.texi - documented new --enable-profiling and --enable-static-link options in installation section; regenerated INSTALL lib/glob/glob.[ch] - new global variable, glob_ignore_case, turns on case-insensitive filename matching in fnmatch() using the FNM_CASEFOLD flag doc/{bash.{1,html},bashref.texi} - documented new shopt `nocaseglob' option 7/15 ---- bashline.c - when glob_complete_word is called with state == 0, make sure we set rl_filename_completion_desired so that proper quoting of the resultant filenames is performed [in bash-2.01.1] 7/16 ---- externs.h, oslib.c - strcasecmp and strncasecmp replacements should have `const char *' as the first two arguments, to match OS definitions [in bash-2.01.1] 7/17 ---- (many files) - changes for minix-2.0, mostly just adding #ifndef _MINIX around include files that minix doesn't provide, like and lib/readline/terminal.c - removed `outchar' function; use _rl_output_character_function in its place support/config.guess - changes to recognize HP_ARCH of `hppa2.0' test.c - new `-N' option: `test -N file' returns true if FILE exists and has been modified since it was last accessed doc/{bash.{1,html},bashref.texi} - documented new `test -N' option 7/22 ---- aclocal.m4 - prefer /var/spool/mail to /usr/spool/mail in BASH_DEFAULT_MAIL_DIR [in bash-2.01.1] lib/readline/{complete,bind}.c - new readline variable, print-completions-horizontally, which causes matches to be printed across the screen (like `ls -x') rather than up-and-down (like `ls') - new readline variable, completion-ignore-case, which causes filename completion and matching to be performed case-insensitively doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo - documented new print-completions-horizontally variable - documented new completion-ignore-case variable _distribution, Makefile.in - bumped the version number up to 2.02-alpha1 bracecomp.c - fixes so that the braces are not quoted by the filename quoting function when complete-into-braces is executed with M-{. The brace completion functions do filename quoting themselves [in bash-2.01.1] pathexp.c - changed quote_string_for_globbing so that it takes a flags word as its second argument pathexp.h - defines for flags passed to quote_string_for_globbing subst.c,execute_cmd.c - changed calls to quote_string_for_globbing to pass the correct flag arguments expr.c - added a `**' binary operator to do exponentiation (2**16 == 65536). precedence is lower than arithmetic operators, higher than unary operators (2**16-1 == 65535) doc/{bash.{1,html},bashref.texi} - documented new `**' arithmetic binary operator 7/24 ---- shell.c - added new (currently undocumented) `--wordexp' option to do the job required by POSIX.2 wordexp(). If -n is supplied along with --wordexp, command substitution is disallowed and the shell exits with a status of 125 if one is attempted. If there is an expansion error, the shell exits with a status of 127. If there is a shell parsing error, the shell exits with a status of 126. Otherwise, the exit status is 0. The current output is number of words\n number of bytes\n expanded words, one per line, separated by newlines This will have to be changed when an interface to glibc is coded 7/28 ---- hashcmd.h - reduced the default size of the filename hash table from 631 to 107 sig.c - don't call initialize_siglist if HAVE_UNDER_SYS_SIGLIST is defined [in bash-2.01.1] siglist.c - don't compile this file if HAVE_UNDER_SYS_SIGLIST is defined [in bash-2.01.1] variables.c - fix to make $RANDOM work better in subshells [in bash-2.01.1] aclocal.m4 - new macro, BASH_DECL_UNDER_SYS_SIGLIST, looks for _sys_siglist in and , defines UNDER_SYS_SIGLIST_DECLARED if found [in bash-2.01.1] - change BASH_UNDER_SYS_SIGLIST to require BASH_DECL_UNDER_SYS_SIGLIST, like BASH_SYS_SIGLIST requires AC_DECL_SYS_SIGLIST [in bash-2.01.1] config.h.in - add a line for UNDER_SYS_SIGLIST_DECLARED [in bash-2.01.1] configure.in - make sure that SVR4_2 is defined for machines that have $host_os sysv4.2* (e.g., sysv4.2MP) as well as $host == sysv4.2 [in bash-2.01.1] 7/29 ---- command.h - new command type, ARITH_COM, used to create and execute a ((...)) command without translating it into let "..." parse.y - changes to the grammar and lexer so that ((...)) is parsed as a command of type ARITH_CMD. An ARITH_CMD is a WORD_LIST, for future expansion, even though only the first word is used make_cmd.c, make_cmd.h - definition and declaration of a function to build an arithmetic command dispose_cmd.c - added code to dispose of arithmetic commands print_cmd.c - added code to print arithmetic commands, both `regularly' and when they're being traced with `set -x' externs.h - extern declaration for xtrace_print_arith_cmd copy_cmd.c - added code to copy arithmetic commands execute_cmd.c - added code to directly execute arithmetic commands -- they are a shell_control_structure, so just about everything like redirections and piping is taken care of by the boilerplate code. All that's needed is to expand the expression (which is within double quotes -- added by parse.y:parse_arith_cmd()), print it if tracing is enabled, call the expression evaluator, and return an appropriate result 7/30 ---- input.c - new function, set_buffered_stream(fd, bp), sets the buffered stream associated with FD to BP and returns the old buffered stream input.h - extern declaration for set_buffered_stream parse.y - call set_buffered_stream rather than manipulating the BUFFERS array directly shell.c - unset_bash_input now takes an argument, CHECK_ZERO.

Some systems, like SVR4, have a B_ERROR define in a file included by jobs.c and nojobs.c, and it causes a warning 7/31 ---- fnmatch.c - rewrote most of fnmatch(), so that it now implements ksh-88 style pattern matching (`[@+*?!](patlist)') if the FNM_EXTMATCH flag is set fnmatch.h - added a define for FNM_EXTMATCH 8/4 --- lib/readline/display.c - fixed _rl_redisplay_after_sigwinch () so that it really redisplays only the portion after the final newline of a multi-line prompt [in bash-2.01.1] bashline.c - attempt_shell_completion no longer returns matches if a glob pattern matches more than one filename -- it caused too many problems [in bash-2.01.1] 8/5 --- lib/glob/glob.c - updated glob_pattern_p so that the extended matching operators are recognized pathexp.c - udpated unquoted_glob_pattern_p so that the extended matching operators are recognized - udpated quote_globbing_chars so that the extended matching operators are recognized and quoted appropriately subst.c - updated match_pattern_char so that the extended matching operators are recognized parse.y - updated read_token_word so that it parses an extended matching pattern as a single word jobs.c - if a job is suspended with SIGTSTP, and the user has set checkwinsize with `shopt', update the window size [in bash-2.01.1] pathexp.c, pathexp.h - new global variable, extended_glob, controls whether the extended pattern matching features are enabled pathexp.h - new define, FNMATCH_EXTFLAG, to be OR'd with other values for flags argument to fnmatch to enable the extended pattern matching features if extended_glob is set {pathexp,execute_cmd,bashhist,subst,test}.c, builtins/help.def - changed calls to fnmatch to add FNMATCH_EXTFLAG to the flags arg if extended_glob is non-zero lib/glob/glob.c - changed flags arg passed to fnmatch to include FNM_EXTMATCH if extended_glob is non-zero (#ifdef SHELL) 8/6 --- builtins/shopt.def - added a new `extglob' shell option, controls the value of extended_glob 8/7 --- doc/{bash.{1,html},bashref.texi} - documented new extended pattern matching operators and the `extglob' shell option tests/{extglob.{tests,right},run-extglob} - test suite for the new extended globbing features 8/8 --- parse.y, pathexp.h, lib/glob/fnmatch.c - made the extended globbing code #ifdef EXTENDED_GLOB config.h.in - added a line for EXTENDED_GLOB, controlled by configure configure.in - new option, --enable-extended-glob, controls defining of EXTENDED_GLOB (on by default) doc/bashref.texi - documented new `configure' `--enable-extended-glob' option 8/11 ---- builtins/printf.def - new `printf' builtin, implemented according to POSIX.2 spec for printf(1) Makefile.in,builtins/Makefile.in - added necessary stuff for new printf builtin 8/12 ---- lib/readline/isearch.c - change to make ^G interrupt the incremental search correctly [in bash-2.01.1] configure.in, config.h.in - configure now checks for the availability of strtoul(3) builtins/printf.def - use strtoul for the `%o', `%u', `%x', and `%X' formats if it is available 8/13 ---- tests/{printf.{right,tests},run-printf} - extensive test suite for the new `printf' builtin builtins/Makefile.in - change so that `builtext.h' is not recreated every time the source file for a builtin is changed if the contents are the same. This keeps many files from being recompiled 8/14 ---- subst.c - changed verify_substring_values so that it returns -1 for substring range errors, 0 for expression errors, and 1 for success [in bash-2.01.1] - changed parameter_brace_substring to return an error if verify_substring_values returns 0, and a null string if it returns -1. This matches the ksh93 behavior [in bash-2.01.1] trap.c - changed decode_signal so that it makes sure the first three characters of a signal name are `SIG' before allowing the `SIG' prefix to be omitted. This is so a signal spec of `T' does not match `EXIT', for instance [in bash-2.01.1] builtins/trap.def - make sure that showtrap() displays traps for signals with unknown names using the signal number [in bash-2.01.1] shell.c - make sure that `bash -r' doesn't turn on the restricted mode until after the startup files are executed [in bash-2.01.1] doc/{bash.{1,html},bashref.texi} - documented printf builtin 8/15 ---- general.c - added \xNNN escape to ansicstr -- NNN are up to three hex digits. This affects $'...', `echo -e', and printf builtins/printf.def - added \xNNN escape to bexpand -- NNN are up to three hex digits. This affects printf's `%b' conversion specifier doc/{bash.{1,html},bashref.texi} - documented new \xNNN escape sequence for echo, $'...', and printf builtins/setattr.def - make sure that a variable found in the temp environment does not cause a null string to be assigned by bind_variable (e.g., foo="" export foo ) [in bash-2.01.1] 8/18 ---- subst.c - fixed a bug that sometimes caused bad memory (pointer into an allocated block) to be passed to free when doing arithmetic substitution. Bug report from stevet@myofb.org [in bash-2.01.1] 8/19 ---- subst.c - considerable changes: moved the code that expands a single $... parameter expansion into a separate function: param_expand() This function returns a string, which may contain characters quoted with CTLESC or CTLNUL without doing word splitting - changed expand_word_internal to not remove the expansion of "$*" if the number of positional parameters is > 0 - changed the '"' case of expand_word_internal to remove quoted nulls from the resultant word if the expansion was not "$@", and the word is not a quoted null string ([] == CTLNUL, [1] == '\0') subst.c, variables.c - moved the code that handles special variables from subst.c to variables.c 8/20 ---- subst.c - rearranged the source a bit to group functions with similar operation together - fixed parameter_brace_expand so that it no longer allows indirect expansion of `special' variables - fixed parameter_brace_expand so taking the length of some of the shell's special parameters works again - moved all of the code that computes the length of a shell parameter (the ${#xxx} expansion) into parameter_brace_expand_length. Previously, the code that handled the lengths of the shell's special parameters was in parameter_brace_expand_word - valid indirect expansions are now only variable names or positional parameters 8/21 ---- subst.c - fixed param_expand to raise an expansion error if $! is being expanded and no asynchronous processes have been created - an expression error in a $((...)) arithmetic expansion now causes a non-interactive shell running in POSIX mode to exit - relaxed change of 8/20 to allow indirect references to $#, $@, $* builtins/bashref.texi - documented new posix-mode exit on invalid expressions in $((...)) lib/readline/complete.c - don't call rl_strpbrk unless rl_filename_quote_characters is not NULL -- strpbrk requires non-NULL arguments [in bash-2.01.1] 8/22 ---- bashline.c - don't make `history-expand-line' a bindable command unless BANG_HISTORY is defined, and don't compile the code for that command in unless BANG_HISTORY is defined - make history_expand_line(), tcsh_magic_space(), alias_expand_line(), and history_and_alias_expand_line() int-returning functions that return 0 for success and non-zero on error. This allows tcsh_magic_space() to just call history_expand_line() and insert a space if that returns successfully - `magic-space' is now a bindable readline command doc/bash.{1,html}, lib/readline/doc/rluser.texinfo - documented new `magic-space' bindable readline command 8/25 ---- parse.y - fixed decode_prompt_string so that values of $PWD longer than PATH_MAX don't cause buffer overruns (char t_string[PATH_MAX]) [in bash-2.01.1] general.c - fixed polite_directory_format so that values of $HOME longer than PATH_MAX don't cause buffer overruns (char tdir[PATH_MAX]) [in bash-2.01.1] subst.c - fix to expansion of $* so that the positional parameters are separated by the first character of $IFS, even when the expansion is not within double quotes, so the correct split is still performed even when IFS does not contain a space. Works for ${*}, too - fix to expansion of $@ so that the positional parameters are separated by the first character of $IFS, even when the expansion is not within double quotes, so the correct split is still performed even when IFS does not contain a space. Works for ${@}, too - new function, string_list_dollar_at(), which is to $@ as string_list_dollar_star is to $* - fixed expansion of $@ so that splitting is still done even if IFS is unset or NULL, as POSIX.2 specifies (section 3.5.2) - fixed expansion of $* so that it expands to multiple words if there is more than one positional parameter, just like $@, even if IFS is unset or NULL - new function list_quote_escapes, quotes (with CTLESC) all CTLESC and CTLNUL characters in each member of the list tests/dollar-{at,star}.sh - combined into dollar-at-star, changed run-dollars accordingly 8/26 ---- Makefile.in - make the `tests' target use $(SHELL) instead of hardcoding `sh' 8/29 ---- subst.c - expand_word_list_internal now takes a flags word as the second argument, telling which expansions to perform on the WORD_LIST - broke expand_word_list_internal into several functions: one each to do brace expansion, glob expansion, and the `normal' shell expansions - new extern function: expand_words_shellexp() to perform the `normal' shell expansions on a WORD_LIST subst.h - extern declaration for expand_words_shellexp bashline.c - fixed a problem with attempt_shell_completion where it attempted to refer to rl_line_buffer[-1] (completion at the start of the line, which means that ti == -1, which means that the test for rl_line_buffer[ti] at line 715 was an array bounds error [in bash-2.01.1] eval.c - new function, parse_string_to_word_list(), which takes a string and runs it through the parser, returning the resultant word list externs.h - new extern declaration for parse_string_to_word_list() variables.c - change assign_array_var_from_string to first split the string between the parens on whitespace, then expand the resultant list of words with all the shell expansions before doing the assignment 9/4 --- redir.c, redir.h - redirection_error is no longer a static function builtins/evalstring.c - changes to handle $( < filename ) (equivalent to $(cat filename)) as in ksh lib/readline/bind.c - added two new functions: rl_unbind_function_in_map(func, map), which unbinds all keys that execute FUNC in MAP; and rl_unbind_command_in_map(command, map), which unbinds all keys bound to COMMAND in MAP lib/readline/readline.h - extern declarations for rl_unbind_{function,command}_in_map lib/readline/doc/rltech.texi - documented rl_unbind_{function,command}_in_map builtins/bind.def - added a new option, -u FUNCNAME, which unbinds all key sequences bound to FUNCNAME in the specified (or current) keymap doc/{bash.{1,html},bashref.texi} - documented new $( < filename ) command substitution - documented new bind -u FUNCNAME option 9/5 --- shell.c - send SIGHUP to all jobs when an interactive login shell exits if the variable `hup_on_exit' is non-zero - modified run_startup_files so that if `NON_INTERACTIVE_LOGIN_SHELLS' is #define'd (perhaps in config.h.top, though there is nothing there for it), all login shells (interactive and non-interactive) run /etc/profile and one of the per-user login shell startup files builtins/shopt.def - new shopt option `huponexit' to control the value of hup_on_exit doc/{bash.{1,html},bashref.texi} - documented new `huponexit' shell option 9/8 --- builtins/common.c - changed contains_shell_metas to return 1 if a tilde appears at the start of a string or after a `=' or `:' - changed backslash_quote to quote a tilde if it appears at the start of a string or after a `=' or `:' lib/readline/complete.c - moved rl_tilde_expand to util.c; it doesn't really have anything to do with completion - moved insert_text to readline.c, renamed it _rl_replace_text (since that's really what it does), changed callers - moved code that postprocesses the list of completion matches into a new function: postprocess_matches - new implementation of tcsh-like menu completion in a single new function: rl_menu_complete lib/readline/{funmap.c,readline.h} - necessary declarations for binding rl_menu_complete to the new `menu-complete' command doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo - documented new `menu-complete' bindable readline command 9/9 --- jobs.c - delete_job should print a warning only if subshell_environment is 0, so we don't print bogus warnings when shell scripts without a leading #! are executed 9/10 ---- builtins/read.def - fixed the code so that the `read' is automatically restarted when it returns -1 with errno == EINTR. SIGINT is handled by the interrupt handler, since interrupt_immediately is set to 1, so this handles things like SIGCHLD [in bash-2.01.1] 9/11 ---- test.c - reorganized the code slightly to make it easier to add the ksh-like [[...]] compound command test.h - new file, with extern declarations for functions available in test.c externs.h - moved declaration of test_command to test.h builtins/test.def - include `test.h' 9/16 ---- {command,make_cmd,dispose_cmd,externs,subst}.h parse.y, subst.c {make,dispose,copy,print,execute}_cmd.c - changes to add the new ksh-93 compatible [[...]] conditional command configure.in - new enable option, --enable-cond-command, to compile in the [[...]] command code config.h.in - new #define, COND_COMMAND, to compile in the [[...]] command code tests/{run-cond,cond.{tests,right}} - test suite for the new [[...]] command {builtins,lib/{readline,glob,tilde}}/Makefile.in - explicit dependencies for .o files on .c files for losing makes like Solaris doc/{bash.{1,html},bashref.texi} - documented the new `[[' compound command - documented the test/[ builtin behavior based on the number of arguments in the description of the builtin - made a new section for conditional expressions that just lists the available primaries -- the connectives and other operators are listed in the description of the [[ command and the test/[ builtin 9/18 ---- builtins/set.def - minus_o_option_commands is now a global function so the shopt code can use it - minus_o_option_commands now takes an argument telling it which options to print, just like list_minus_o_options - new function, print_minus_o_option, which prints the value of a `set -o' option either in the traditional format or in the format used by `set +o' - changed list_minus_o_opts and minus_o_option_commands to call print_minus_o_option builtins/shopt.def - `shopt -p' now causes output to be printed in a format reusable as input (the format is a series of shopt commands, like the output of `set +o') - fixed a bug that made `shopt -so' and `shopt -uo' not work - fixed list_shopt_o_options so that `shopt -op' acts like `set +o' - fixed list_shopt_o_options to that `shopt -op optname' prints the value of optname in a reusable format - fixed list_some_o_options so that `shopt -ops' and `shopt -opu' work and display output in a reusable format 9/19 ---- doc/{bash.{1,html},bashref.texi} - documented new `shopt -p' behavior shell.c - made `bash +o' display the same output as `set +o' and then start an interactive shell (previously `bash -o' and `bash +o' displayed the same thing) builtins/common.h - added prototypes to the extern function declarations 9/22 ---- builtins/evalstring.c - fixed the DISCARD case of the jump_to_top_level so that it doesn't try to call dispose_command(command) after the `pe_dispose' unwind frame gets run, since that disposes the command 9/23 ---- test.[ch] - test_eaccess is now a global function so that globbing code can use it lib/glob/glob.c - rewrote glob_vector to be slightly more efficient and to not read the directory if the filename pattern does not contain any globbing chars. This satisfies the POSIX requirement that read permission is not required for a directory when the pathname component does not contain a pattern character (bug reported by jsm28@cam.ac.uk) subst.c - fixed parameter_brace_expand so that ${array[@]} and ${array[*]} behave correctly when IFS is unset or set to something that does not contain a space (they should result in separate words, just like $@ and $*) tests/{run-array2,array-at-star,array2.right} - tests for the expansions of ${array[@]} and ${array[*]}, derived from the tests in dollar-at-star 9/24 ---- jobs.c - fixed cleanup_dead_jobs so that it doesn't remove the job containing last_asynchronous_pid from the job table. This fixes the POSIX.2 `wait' requirement problem 9/25 ---- parse.y - added `\r' escape sequence to the prompt expansion code lib/readline/chardefs.h - added defines for ISOCTAL, OCTVALUE, isxdigit (if not defined), and HEXVALUE lib/readline/bind.c - added `normal' echo/printf-like backslash escapes to the key sequence translation code, with the addition that \d expands to RUBOUT. This means that key sequence definitions (before the `:') and macro values may contain these special backslash-escape sequences - now that we can translate octal escape sequences in key bindings, change _rl_get_keyname so that it turns characters with values 128-159 inclusive into octal escape sequences (\200-\237), since those characters are not ASCII or ISO Latin 1 doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo - documented new backslash escapes for readline key sequence and macro translation builtins/pushd.def - new function, get_dirstack_from_string(char *string), returns an element from the directory stack or null, treating the argument exactly as `dirs string' would, with the exception that if the first character of `string' is not `+' or `-', a `+' is assumed builtins/common.h - new extern declaration for get_dirstack_from_string general.c - added code to bash_special_tilde_expansions to get the expansion using get_dirstack_from_string() if the first character of the tilde-prefix is a digit or the first character is a `+' or `-' and the second is a digit tests/dstack.{tests,right} - renamed from dirstack.{tests,right} tests/dtack2.{tests,right} - new tests for the directory stack tilde expansion code tests/run-dirstack - now runs both dstack and dstack2 10/3 ---- trap.c - reordered header file inclusion for irix 4 execute_cmd.c - fixed select_query so that a reply that is not a number is treated the same as a numeric reply that is out of range lib/readline/util.c - added a backwards-compatibility definition of _rl_savestring() builtins/set.def - initialize_shell_options now takes an argument saying whether or not we should parse $SHELLOPTS from the environment. The shell does not parse the value if it's restricted, running setuid, or running in `privileged mode' shell.c - change call to initialize_shell_options to add the correct argument builtins/common.h - changed extern declaration for initialize_shell_options doc/{bash.{1,html},bashref.texi} - added note that the shell ignores $SHELLOPTS in the environment at startup if running in privileged mode - added note that the restricted shell does not parse $SHELLOPTS from the environment at startup 10/6 ---- aclocal.m4 - change BASH_RLIMIT_TYPE so that it looks for rlim_t in as well as , for Solaris 2.6 - new macro, BASH_LARGE_FILE_SUPPORT, to enable special compilation options for large files on Solaris 2.6 (from eggert@twinsun.com) mailcheck.c - the `file_size' member of the FILEINFO struct should be of type `off_t' - the `size' variable in file_has_grown should be of type `off_t' - the RESET_MAIL_FILE macro should initialize file_size to 0, not 0L builtins/Makefile.in - LDFLAGS and LOCAL_LDFLAGS are now set by configure - `mkbuiltins' is now created from `mkbuiltins.o' instead of directly from the source to the executable builtins/evalfile.c - fixed _evalfile so that it handles large files correctly on systems where the st_size member of `struct stat' will not fit into an `int' builtins/mkbuiltins.c - don't assume that st_size fits into an int input.[ch] - the `b_size' member of a struct BSTREAM is now of type `size_t' - changed third argument to make_buffered_stream to size_t; changed caller - changed `size' variable in fd_to_buffered_stream to type `size_t' general.h - include if HAVE_SYS_RESOURCE_H and RLIMTYPE are both defined, for possible necessary definition of RLIMTYPE (e.g., on Solaris 2.6) {execute_cmd,jobs}.c, builtins/times.def - don't include explicitly if RLIMTYPE is defined, since general.h will include it in that case lib/readline/bind.c - new function, char *_rl_read_file(filename, sizep), which reads FILENAME into a malloced buffer, returning the buffer and the size of the buffer in *SIZEP lib/readline/histfile.c - changed read_history_range and history_truncate_file to handle large files hashcmd.c - find_hashed_filename should not add `./' to the front of a pathname that already begins with `./' 10/8 ---- support/config.sub - recognize `hppa2.0' as a valid machine architecture aclocal.m4 - changed BASH_CHECK_LIB_TERMCAP so that `gnutermcap' is not chosen if `$prefer_curses' is set to something bashhist.c - don't use HISTCONTROL or HISTIGNORE to remove lines from the second and subsequent lines of a multi-line command (current_command_line_count > 1). Old code did this only when command-oriented-history was enabled doc/{bash.{1,html},bashref.texi} - changed descriptions of HISTCONTROL and HISTIGNORE to state that these variables are not applied to the second and subsequent lines of a multi-line command builtins/hash.def, {copy,dispose}_cmd.c - include "bashtypes.h" -- cray machines need it because of their oddball definition of `word' configure.in - changed check of ${host_cpu} to check for `*cray*' and `*Cray*' when deciding whether to include the GNU malloc, since it seems that ${host_cpu} gets set to `CrayYMP' 10/9 ---- configure.in - look for strtod and strtol in libc - make lib/sh directory in build directory if not there - create lib/sh/Makefile config.h.in - added HAVE_STRTOD and HAVE_STRTOL Makefile.in - changes for lib/sh/libsh.a (shell library) builtins/printf.def - took out the `#ifdef STRTOUL' code, since strtoul is in libsh.a, and will be resolved from there if it's not in libc variables.c - call strtol() instead of string_to_long() general.c, general.h - removed string_to_long - changed legal_number to use strtol so it correctly sets errno to ERANGE on overflow - moved bash_getcwd_errstr here from lib/sh/oslib.c externs.h - moved extern declarations for functions defined in libsh to a separate section of the file, added extern declarations for other functions in libsh builtins/ulimit.def - changed macro definition for string_to_rlimtype to call strtol directly instead of string_to_long lib/sh/clktck.c - moved get_clock_tck to its own file, since it's compiled in unconditionally 10/10 ----- lib/sh/getenv.c - moved getenv() and __getenv() here from lib/sh/oslib.c lib/sh/{setlinebuf,strerror,strcasecmp}.c - moved {setlinebuf,strerror,strcasecmp}() from oslib.c to individual files lib/sh/Makefile.in, Makefile.in - changes for new files in lib/sh aclocal.m4 - new macro BASH_SYS_RESTARTABLE_SYSCALLS, which does what AC_SYS_RESTARTABLE_SYSCALLS does, but using posix sigaction() configure.in - call BASH_SYS_RESTARTABLE_SYSCALLS if ac_cv_sys_restartable_syscalls is `no' 10/13 ----- builtins/jobs.def - catch out-of-range jobs better in disown_builtin configure.in - don't build with GNU malloc on cygwin32 trap.c - change signal_name to handle the case where signal_names[sig] is NULL, which can happen on cygwin32 execute_cmd.c - changes to do_piping to make pipes text mode (O_TEXT) on cygwin32 cross-build - new directory with cache files and other stuff for cross-compiling bash (currently only for building for cygwin32 on a Unix machine) cross-build/cygwin32.cache - new file containing configuration variable assignments for cygwin32 that would otherwise require a default case for AC_TRY_RUN configure.in - source ${srcdir}/cross-build/cygwin32.cache on CYGWIN32 systems if we're cross-compiling on a unix machine - set $CC_FOR_BUILD for cygwin32 cross-compiling environment Makefile.in - CC_FOR_BUILD is now a variable set by configure builtins/mkbuiltins.c - only check for read(2) returning <= 0 in extract_info() (error and exit on < 0, warning and return on == 0) builtins/evalfile.c - only check for read(2) returning <= 0 in _evalfile() (error and and failure return on < 0, success on == 0 while short-circuting rest of operation) 10/14 ----- vprint.c - moved to lib/sh/vprint.c lib/sh/Makefile.in - added entries for vprint.[co] in the appropriate places cross-build/win32sig.h - a version of signames.h for cross-compiling for the CYGWIN32 environment on a Unix machine (from noer@cygnus.com) aclocal.m4 - made all cases of AC_TRY_RUN and AC_TRY_COMPILE have reasonable default cases for cross-compiling, and tell the user what they are Makefile.in - removed vprint.c from shell sources and vprint.o from shell objects - added a level of indirection for signames.h -- the variable SIGNAMES_H is set by configure to either `lsignames.h' or a file for a cross-compilation environment (currently only the cygwin32 stuff is supported). Then that file is copied to `signames.h'. `lsignames.h' is created by `mksignames' as was previously used to create signames.h directly configure.in - set SIGNAMES_H to either `$(srcdir)/cross-build/win32sig.h' or `lsignames.h' as appropriate, substitute into Makefile 10/15 ----- builtins/Makefile.in - CC_FOR_BUILD is now set by configure and used to build mkbuiltins and psize.aux variables.h - new variable attribute `att_tempvar', set if the SHELL_VAR * was constructed on the fly from the temporary environment variables.c - find_name_in_env_array now sets the `att_tempvar' attribute on the SHELL_VAR it creates findcmd.c - search_for_command now disposes the SHELL_VAR created by searching the temporary environment for $PATH, if it is found there - _find_user_command_internal also disposes of the SHELL_VAR if it has the `att_tempvar' attribute set builtins/setattr.c - show_name_attributes looks in the temporary environemnt, so it needs to dispose the SHELL_VAR if it has the att_tempvar attribute set subst.c - parameter_brace_expand_word now disposes of the SHELL_VAR returned by find_variable if it has the att_tempvar attribute set - ditto for param_expand and word_split builtins/kill.def - disallow null pid arguments instead of treating them as 0 - display a usage message and return failure if no pid or job arguments are supplied 10/16 ----- builtins/declare.def - make `var=value declare -x var' behave the same as `var=value export var' and `var=value declare -r var' behave the same as `var=value readonly var', now that we have the `tempvar' attribute 10/22 ----- jobs.c - non-interactive shells shouldn't report jobs killed by a SIGINT, even if the standard output is to a terminal - pretty_print_job should add a CR at the end of its output if the shell is interactive and asynchronous notification is being performed. This fixes the problem with extra CRs in the output of $(jobs) general.c - changed canonicalize_pathname to change `//' into `/', but leave other pathnames starting with two consecutive slashes alone 10/27 ----- lib/readline/histexpand.c - fixed history_expand so that the appearance of the history comment character at the beginning of a word inhibits history expansion for the rest of the line 10/29 ----- jobs.c,variables.c - moved set_pipestatus_array to variables.c variables.c - new function, set_pipestatus_from_exit(int), which sets the PIPESTATUS variable from a command's exit status variables.h - extern declarations for set_pipestatus_from_exit and set_pipestatus_array execute_cmd.c - fixed execute_simple_command to call set_pipestatus_from_exit if a foreground builtin or function, or a foreground null command is executed 10/31 ----- shell.c - fixed run_startup_files to detect being run by sshd, and treat that case as equivalent to being run by rshd 11/3 ---- builtins/set.def - make sure `set -a' doesn't cause SHELLOPTS to be exported when a change is made to one of the shell options 11/4 ---- pathexp.c - fix to shell_glob_filename in the code that uses a POSIX glob library 11/5 ---- jobs.c - fix cleanup_dead_jobs to hang onto the job corresponding to last_asynchronous_pid only if the shell is not interactive (this still has the problem that until a new async process is started, the job will stay in the jobs table) configure.in,aclocal.m4 - added a new macro, BASH_TYPE_U_INT32_T, to check for u_int32_t separately from int32_t, since there are systems (HP-UX 10.20) that have a define for the latter but not the former 11/6 ---- jobs.c - cleanup_dead_jobs no longer checks whether the job it is deleting corresponds to last_asynchronous_pid - notify_of_job_status and mark_dead_jobs_as_notified now will not mark the job corresponding to last_asynchronous_pid as notified if the shell is not interactive - wait_for_single_pid, if told to wait for last_asynchronous_pid, or the job of which it is a member, will take care of marking the job as notified after calling wait_for and collecting the status. This means that two successive `wait' calls for $! will succeed the first time and fail the second, as POSIX.2 specifies (take this code out if it causes problems) 11/7 ---- jobs.c - wait_for_job, if told to wait for the job corresponding to the last async pid, will mark the job as notified after waiting for it and collecting the status general.h - fixed MEMBER macro to avoid reading past end of S (it used to test s[1] before s[0], which is an error if s == "") subst.c - expand_word_internal should free ISTRING before returning if param_expand returns an error - parameter_brace_expand_word should free the memory it allocates and passes to param_expand execute_cmd.c - execute_arith_command should call dispose_words on the list returned by expand_words parse.y - after calling parse_arith_command, read_token needs to free the string value that parse_arith_command fills in, since make_word makes a copy of the string it's passed 11/10 ----- subst.c - cond_expand_word needs to free the value returned by string_list after it is run through quote_string_for_globbing parse.y - make sure cond_term frees yylval.word if it is just a `!' and it's parsed as a term negation operator variables.c - assign_array_var_from_string needs to free the word list returned by parse_string_to_word_list after calling expand_words_shellexp on it execute_cmd.c - changed execute_simple_command to avoid saving the_printed_command into command_line until just before it's needed. This should save time and prevent memory leaks on errors, but it must be watched closely to make sure that the_printed_command doesn't change out from under execute_simple_command before we copy it 11/12 ----- builtins/alias.def - alias and unalias should print error messages when passed an argument that is not an alias for printing or deletion, respectively, even if the shell is not interactive builtins/exit.def - `logout' will no longer exit a non-login non-interactive shell 11/17 ----- lib/readline/nls.c - add `koi8-r' as a legal LANG value builtins/alias.def - if `alias' or `alias -p' is executed when no aliases are defined, the return status should be 0, according to POSIX.2 11/18 ----- subst.c - changed a couple of calls to make_word_list (make_word(z), ...) to add_string_to_list (z, ...) execute_cmd.c - execute_cond_command now sets this_command_name to `[[' 11/21 ----- variables.c - all_visible_{function,variable}s and the functions they call should be compiled in only if READLINE is defined 11/24 ----- aclocal.m4 - remove some leading whitespace before preprocessor statements in BASH_KERNEL_RLIMIT_CHECK general.[ch] - fix declarations for group_member so the extern declaration in general.h agrees with the definition in general.c (fix from Andreas Schwab ) builtins/cd.def - print the new working directory if the shell is interactive and `cd -' succeeds - don't print the new working directory if it's found in $CDPATH if the shell is not interactive 11/25 ----- builtins/cd.def - fixes to bindpwd so that it copes with get_working_directory returning NULL (bug from schwab@issan.informatik.uni-dortmund.de) 12/2 ---- support/config.guess - add support for new OS name for SINIX SVR4 systems 12/3 ---- builtins/set.def - `unset' should check that a function it's trying to unset is a legal identifier only when in POSIX mode redir.c - changed here_document_to_fd to try and make sure the filename used for the here document is `more unique', since the old version would fail if two here documents were created in less than a second 12/4 ---- builtins/cd.def - POSIX.2 says that if CDPATH is used to find the new directory, and it's not relative to the current directory, the new directory name should be displayed on stdout even if the shell is not interactive 12/5 ---- parse.y - changes so that `time' is recognized as a reserved word only at the beginning of a pipeline (the last read token is one of 0, `;', `\n', `&&', `||', or `&'): o add clause to special_case_tokens that does the check and returns TIME if the conditions are met o take check for `TIME' out of CHECK_FOR_RESERVED_WORD, but leave it in the word_token_alist so that `type' still reports it as a `keyword' o new function, time_command_acceptable(), encapsulates the necessary conditions for `time' to be returned as a reserved word [bash-2.02-alpha1 frozen] 1/6/1998 -------- lib/glob/fnmatch.c - fix define for isgraph so that it does not return success for space - fix strcompare() so that the call to strcoll is surrounded by #ifdef HAVE_STRCOLL 1/7 --- lib/glob/fnmatch.c - the `test' argument to brackmatch() should be of type `unsigned char' 1/11 ---- execute_cmd.c - make sure execute_arith_command sets this_command_name to `((' 1/29 ---- parse.y - make sure the code for pushing and popping strings is compiled in if either ALIAS or DPAREN_ARITHMETIC is defined, because the (( code uses push_string in the case of a nested subshell - fix cond_skip_newlines so it resets the prompt to $PS2 while parsing an unfinished conditional command dispose_cmd.c, copy_cmd.c, builtins/hash.def - fixes to not use `word' as a variable name or the name of a function parameter to get around stuff in the Cray Unix include files builtins/printf.def - return failure immediately if an illegal format character is encountered redir.c - make the code that creates here-documents behave better if the file it's trying to create already exists for some reason lib/readline/complete.c - changed print_filename to return the number of characters it outputs; changed callers to use that value. This makes columns line up when printing completion listings with filenames containing control characters doc/bash.{1,html} - fixed a typo in the quote removal section 1/30 ---- parse.y - free_string_list() needs to check that t->expander is not NULL before trying to dereference it - reset_parser() doesn't need to set pushed_string_list to NULL after calling free_string_list(), since free_string_list does it configure.in,cross-build/cygwin32.cache - fixes from Geoff Noer for better cygwin32 cross-compilation tests/printf.{tests,right} - removed test for integer overflow, since error messages differ across systems pathexp.c - fixed a problem with unquoted_glob_pattern_p that made things like `x+*' not expand correctly lib/glob/glob.c - fixed a problem with glob_pattern_p that made things like `x+*' not expand correctly builtins/cd.def - if `cd -P' is executed, or `set -o physical' has been executed, the value of $PWD after a successful cd will not contain any symlinks, regardless of whether or not the shell is in posix mode 2/3 --- lib/readline/shell.c - include or as appropriate 2/4 --- builtins/common.c - take out the code in backslash_quote() that looks for tildes to quote, for the time being - if getcwd() fails, get_working_directory now prints the error message corresponding to errno in addition to the rest of the information -- TENTATIVE CHANGE lib/sh/getcwd.c - fix from Paul Smith to make getcwd() behave better in the presence of lstat(2) failures stringlib.c - when copying the replacement string into the output string being constructed, strsub() needs to make sure enough space for the replacement string is allocated, not the length of the pattern (use REPLEN, not PATLEN) mailcheck.c - make sure make_default_mailpath() has a valid current_user struct before trying to construct the default mailpath 2/5 --- execute_cmd.c - execute_builtin needs to call run_unwind_frame if the builtin is `source' or `eval' and we're not in a subshell rather than just calling dispose_builtin_env, because not all invocations copy the temporary_env to builtin_env, and nested calls to `.' require that the temporary env given to the first persist until that first call to `.' finishes parse.y - fix to history_delimiting_chars so that function definitions like function xyz { echo a } are saved to the history correctly when command_oriented_history is enabled, but literal_history is not bashhist.c - when calling internal_error from pre_process_line, use "%s" as the format with history_value as the argument to avoid the problem with the failed history event containing printf escape sequences 2/13 ---- shell.c - if shell_initialized is non-zero, don't line-buffer stderr and stdout in shell_initialize on SunOS5 -- see if this fixes the crashing problems for scripts without a leading `#! /bin/sh' 2/17 ---- bashline.c - added diffs to _ignore_completion_names from Andreas Schwab to complete names that would otherwise be ignored with FIGNORE if they are the only possible completions. Define NO_FORCE_FIGNORE if you want this; it is not defined by default 2/19 ---- support/bashbug.sh - changed the bug-bash address to bug-bash@gnu.org examples/loadables/Makefile.in - converted from `Makefile' with some boilerplate configure variables to find the source and build directories -- still requires some hand-editing to get the right CFLAGS and LDFLAGS for shared object creation Makefile.in - create examples/loadables/Makefile with `make makefiles' configure.in - create examples/loadables directory so `make makefiles' can write a makefile there general.c - make sure initialize_groups_array always sets things up so that ${GROUPS[0]} is the user's primary group (current_user.gid) 2/20 ---- lib/readline/parens.c - change the time delay when showing matching parens from 1.5 sec to 0.5 sec 2/23 ---- shell.c - isnetconn() should call getpeername(fd,...) instead of using 0 (though fileno(stdin) should always be 0) support/config.guess - updates from master FSF copy 2/24 ---- support/man2html.c - modified version of man2html to convert bash.1 into bash.html support/Makefile.in - simple Makefile to create man2html configure.in - make sure support/Makefile is created Makefile.in - make sure support/Makefile is created and cleaned doc/Makefile.in - changes to suffix rules to say how to make .html from .1 - `bash.html' is now a makefile target, created by man2html from bash.1 rather than being hand-modified lib/sh/itos.c, general.c - new file, itos() from general.c. This is here because the implementation of strerror in lib/sh/strerror.c uses itos() Makefile.in, lib/sh/Makefile.in - changes to add itos.c in libsh.a externs.h, general.h - moved extern declaration of itos() from general.h to externs.h aclocal.m4 - changes to BASH_LARGE_FILE_SUPPORT for the LFS64_* variables in Solaris 2.6 Makefile.in - make sure configure sets CPPFLAGS in this file 2/27 ---- builtins/command.def - make sure get_standard_path returns the value of STANDARD_UTILS_PATH if _CS_PATH is defined, but confstr(3) returns 0, indicating that _CS_PATH does not have a defined value bashhist.c - fixed bash_history_inhibit_expansion() so that extended globbing expressions like *.!(c) are not history expanded if extended_glob is non-zero (shopt -s extglob has been executed) 3/2 --- Makefile.in - changed release status to `beta1' [bash-2.02-beta1 frozen] 3/17 ---- lib/readline/vi_mode.c - make sure _rl_vi_save_insert() gets a non-null UNDO_LIST pointer before trying to do anything with it jobs.c - add a call to internal_warning from wait_for_job if the job is stopped - changed notify_of_job_status to not report pipelines exiting due to SIGPIPE in non-interactive shells if the shell is compiled with -DDONT_REPORT_SIGPIPE builtins/psize.sh - some fixes to try to avoid /tmp file races and surreptitious substitutions version.c - changed the extended version info to show 1998 as the copyright year parse.y - fixes from Andreas Schwab for compilation errors when the shell is configured --disable-alias but with dparen arithmetic enabled eval.c - fixes from Andreas Schwab to make sure the input stream is popped correctly when performing an array assignment in the command argument to `bash -c', e.g., `bash -c 'A=()'' builtins/kill.def - make `kill' with no arguments print a usage message and return a failure status alias.c - fix so that rd_token doesn't dump core when trying to do alias expansion on a line containing an unclosed single quote (fix from Vasco Pedro ) builtins/cd.def - fix so that using a non-empty directory from CDPATH to construct the name of the directory to change to results in an absolute pathname of the new current working directory being displayed, as POSIX.2 specifies support/bashbug.sh - a couple of small fixes to minimize /tmp file races -- the script is still raceable, the window is just smaller 3/24 ---- variables.c - make sure assign_in_env passes a malloc'd string to expand_string_unsplit, because some of the error code assumes that it is malloc'd and frees it (bug reported by Marko.Makela@HUT.FI) 3/25 ---- doc/bashref.texi - changed the email addresses to use the @email texinfo tag trap.c - call reset_parser from the exit trap code before calling parse_and_execute, so reserved words are parsed correctly subst.c - make sure parameter_brace_patsub expands the pattern string as if the expression were not in double quotes, even if the entire expansion is enclosed in double quotes, so that quote removal on embedded double quotes is performed correctly (bug report from schwab@issan.informatik.uni-dortmund.de) 3/27 ---- support/config.guess - changes to allow Power PCs running Apple's Rhapsody to configure 3/31 ---- Makefile.in - changed release status to `beta2' [bash-2.02-beta2 frozen] 4/6 --- subst.c - make sure command_substitute does not try to set the terminal's process group to a background job [bash-2.02 frozen] 4/18 ---- [bash-2.02 released] 4/20 ---- bashline.c - make sure that rl_defun is not called for history-and-alias-expand-line unless both ALIAS and BANG_HISTORY are defined [in bash-2.02.1] 4/22 ---- make_cmd.c - make sure that make_here_document allocates enough space for the first line of the here document, by using the line length +2 (instead of 1000, which is what the old code did, and breaks if the first line of the here document is enough longer than 1000 characters to cause other memory to be scribbled on) [in bash-2.02.1] builtins/cd.def - when in posix mode, a value of "" for CDPATH should be treated the same as the current directory, not result in an error [in bash-2.02.1] lib/malloc/malloc.c - change the mh_align member of `union mhead' to be of type double rather than a pointer, so that malloc will return (hopefully) 8-byte aligned memory [in bash-2.02.1] 4/23 ---- aclocal.m4 - add a new macro to check whether or not off_t is 64 bits 4/24 ---- configure.in - fixed a typo so the bash malloc is not compiled in on mips-sgi-irix6 lib/readline/display.c - fix for readline redisplay if the prompt string is longer than the screen width and includes invisible characters [in bash-2.02.1] jobs.c - make_child should not set the terminal's process group to pipeline_pgrp if pipeline_pgrp == shell_pgrp (indicating that we are forking a child for a command substitution) [in bash-2.02.1] subst.c - in execute_simple_command, in the child forked if there is a pipe or the command is asynchronous, set subshell_environment to SUBSHELL_ASYNC only if the command is asynchronous, SUBSHELL_FORK if there is a pipe in or out [in bash-2.02.1] 4/27 ---- support/texi2dvi - upgraded to version 0.8 (from 0.5) support/texi2html - upgraded to version 1.52 (from 1.51) support/config.sub - config.sub now recognizes all the permutations of the system name that config.guess produces for alphas [in bash-2.02.1] aclocal.m4 - changed BASH_TYPE_INT32_T, BASH_TYPE_U_INT32_T, and BASH_TYPE_PTRDIFF_T to avoid compiling a program; instead use the values determined by the AC_CHECK_SIZEOF tests to determine the default values to supply to AC_CHECK_TYPE configure.in - don't call AC_CHECK_TYPE({int32_t,u_int32_t,ptrdiff_t}) from configure.in; use the updated BASH_TYPE macros instead builtins/exec.def - if shell_execve fails, set ARGS to null because the realloc() call by shell_execve may have caused it to be reallocated and freed -- we don't want to free the memory twice lib/glob/fnmatch.c - fixes from ache@nagual.pp.ru to make fnmatch work for eight-bit characters when `isupper' and `islower' are used -- they were restricted to ASCII characters before, probably to work around some ancient, broken C libraries in which is{low,upp}er are valid only for ASCII characters and return bogus values otherwise [in bash-2.02.1] 4/29 ---- builtins/cd.def - fixed a problem with the shell displaying the old working directory instead of the new one after changing to a directory found via $CDPATH when in physical mode (set -o physical) [in bash-2.02.1] make_cmd.c - make make_cond_command initialize the line number from the cond_node that's passed as an argument (not that it's used right now) copy_cmd.c - make sure that copy_cond_command copies the type of the cond command, since execute_cond_command uses that to decide what kind of test to perform [in bash-2.02.1] builtins/printf.def - make sure the for loop that processes the format string actually consumes arguments; otherwise process it only once to avoid infinite loops (e.g., `printf " " abc def ghi') [in bash-2.02.1] - if the format string is empty after preprocessing by ansicstr, return immediately [in bash-2.02.1] tests/run-printf - use `diff -a' so the presence of a non-printing character in the output doesn't confuse diff into thinking the files are binary (test whether or not `diff' supports `-a' first) Makefile.in - keep $(LOCAL_LIBS) from being specified twice 4/30 ---- support/shobj-conf - a script to generate variables to do shared object configuration for the loadable builtin stuff configure.in - added a section for shared object configuration using an `eval' of the output of shobj-conf and substituting the generated values with AC_SUBST examples/loadables/Makefile.in - the system-specific shared object configuration variables are now substituted by configure 5/4 --- builtins/ulimit.def - some changes for HPUX 9.x's peculiar handling of RLIMIT_FILESIZE - changed the limit retrieval functions to return an error code and the value in a reference argument to avoid use of RLIM_INVALID general.c - new function, get_group_array(), which returns an array of gids examples/loadables/{id,printenv,sync,uname,whoami,push}.c - new loadable builtins variables.c - moved code that initializes $PPID into a new function, set_ppid() variables.h - extern declaration for set_ppid() 5/6 --- subst.c - make sure that the `"' (double-quoted string) case of expand_word_internal calls string_list_dollar_at if we've expanded a double-quoted $@ so correct splitting on $IFS is done when the expansion is complete. We can't simply call string_list because that forces a space separator, and $IFS may not contain a space [in bash-2.02.1] 5/7 --- builtins/umask.def - broke the code that parses a symbolic mode out of symbolic_umask into a separate function that takes a symbolic mode and an initial set of bits to modify examples/loadables/mkdir.c - new loadable builtin 5/11 ---- builtins/printf.def - use the format string length provided by ansicstr() to process the format string, rather than testing for nullness, to handle NUL bytes in the expanded format string builtins/pushd.def - changes so it can be built as both a regular builtin and a loadable builtin from the same source examples/loadables/Makefile.in - changes to build pushd.c from ${topdir}/builtins/pushd.def and then compile it with the correct flags to make it a loadable builtin, even if PUSHD_AND_POPD is not defined in config.h 5/12 ---- lib/readline/complete.c - use rl_completer_quote_characters instead of #ifdef SHELL/#endif code in make_quoted_replacement. This means complete.c no longer has any #ifdef SHELL code 5/13 ---- builtins/Makefile.in - `make clean' should remove mkbuiltins.o Makefile.in - all of the various `clean' targets need to descend into lib/sh and run the appropriate target there builtins/type.def - changed to use the builtin getopt. The old long options are handled by prescanning the argument list looking for the long options, processing them, and taking them out of the list before passing it to internal_getopt() lib/readline/signals.c - removed #ifdef SHELL code -- job control signals and SIGTERM are always set in rl_set_signals, but are set to SIG_IGN if the old handler was SIG_IGN (as bash sets it) - new function rl_maybe_set_sighandler, which sets the signal disposition back to SIG_IGN if the old handler was SIG_IGN - removed #ifdef HANDLE_JOB_SIGNALS and #ifdef HANDLE_SIGTERM code lib/readline/rltty.c - removed #ifdef SHELL code -- set_winsize is always called to force the application to stop if it's not in the foreground before getting the tty attributes 5/14 ---- lib/readline/signals.c - readline now catches SIGQUIT and cleans up the tty before resending it to its container application (unless the calling application has set the disposition of SIGQUIT to be SIG_IGN) - rl_handle_sigwinch is now called rl_sigwinch_handler - rl_sigwinch_handler now calls rl_resize_terminal to fetch the screen size after a SIGWINCH - the sighandler_cxt struct for non-posix systems now includes sa_flags and sa_mask variables, for future use - new variable, rl_catch_signals, indicating that readline should install its own signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP, SIGTTIN, and SIGTTOU - new variable, rl_catch_sigwinch, indicating that readline should install its own SIGWINCH handler, which will chain to a calling application's SIGWINCH handler - new function, rl_free_line_state(), to free up variable state associated with the current line after receiving a signal - new function, rl_cleanup_after_signal(), to clean up the display and terminal state after receiving a signal - new function, rl_reset_after_signal(), to reinitialize the terminal state after a signal handler returns and readline continues - rl_set_signals and rl_clear_signals now look at the values of rl_catch_signals and rl_catch_sigwinch lib/readline/terminal.c - new function rl_resize_terminal (), to reset readline's idea of the screen size after a SIGWINCH lib/readline/readline.h - extern declarations for rl_resize_terminal(), rl_free_line_state(), rl_cleanup_after_signal(), rl_reset_after_signal() - extern declarations for rl_catch_signals and rl_catch_sigwinch variables.c - new functions, get_env_value(char *) and get_home_dir(void) to satisfy references from the tilde and readline libraries when they are compiled as part of bash lib/tilde/tilde.c - rely on extern declarations of get_env_value and get_home_dir; there is no more #ifdef SHELL code lib/readline/shell.c - implementation of get_home_dir that uses getpwuid() to satisfy references from tilde.c when not compiled as part of bash - removed savestring() - removed #ifdef SHELL/#endif pair -- all of these functions will be resolved from bash when readline is linked into bash lib/readline/savestring.c - new file, with function definition for savestring() for backwards compatibility Makefile.in, _distribution - bumped things up to bash-2.03-alpha 5/15 ---- lib/readline/rlconf.h - removed #ifdef SHELL/#endif pair, so the callback stuff will be compiled into libreadline, but never linked into bash (since it's not referenced) configure.in - added new `--with-installed-readline' option to allow readline to be linked with an already-installed version -- this will probably not work with versions of readline prior to 2.3 (libreadline.so.4) [THIS IS STILL UNDOCUMENTED] Makefile.in - changed necessary variables to allow the `--with-installed-readline' option to work; shared and static libraries are supported 5/18 ---- lib/readline/display.c - _rl_save_prompt is now rl_save_prompt; _rl_restore_prompt is now rl_restore_prompt lib/readline/readline.h - extern declarations for rl_save_prompt and rl_restore_prompt lib/readline/{search,isearch,readline,display}.c - converted calls to _rl_{save,restore}_prompt () to use new public versions lib/readline/doc/rltech.texinfo - documented new public functions rl_{save,restore}_prompt 5/19 ---- lib/readline/readline.c - new hook function variable, rl_pre_input_hook. If non-zero, it's called from readline_internal_setup just before it returns and readline starts reading input lib/readline/readline.h - extern declaration for rl_pre_input_hook lib/readline/doc/rltech.texinfo - documented new variable rl_pre_input_hook 5/20 ---- lib/readline/complete.c - new hook function variable, rl_completion_display_matches_hook. If non-null, this function is called when readline would normally display the list of completion matches lib/readline/readline.h - extern declaration for rl_completion_display_matches_hook lib/readline/doc/rltech.texinfo - documented rl_completion_display_matches_hook lib/readline/readline.c - if RL_LIBRARY_VERSION is not defined, define it to 4.0 to match the version number of the shared libraries lib/readline/doc/{hist,rlman}.texinfo - changed the version and edition to 4.0 to match the library version support/config.guess - added case clause for matching UnixWare 7 from SCO (SVR5) -- further work may be needed [These fixes were in a usenet posting from hops@sco.com] support/config.sub - added case clauses to recognize various aliases for SCO Open Server and Open Desktop [in bash-2.02.1] - broke the code that canonicalizes unixware into unixware2 and unixware7 clauses (multiple places) [in bash-2.02.1] - added clause to recognize `sysv5' for SVR5 [These fixes were in a usenet posting from hops@sco.com] [in bash-2.02.1] configure.in - add `-b elf' to LOCAL_CFLAGS for sco3.2v5* to allow dynamic linking (and loadable builtins) - add AC_DEFINE(SVR5) on SVR5 (unixware 7) config.h.in - add #undef SVR5, set by configure 5/21 ---- shell.c - line-buffer stdout and stderr in shell_initialize only if shell_initialized is 0 on all systems, not just SunOS 5 [in bash-2.02.1] support/rlvers.sh - script to print out the version number of any installed readline library configure.in - only allow --with-installed-readline if the version of the installed readline library is 4.0 or greater 5/22 ---- lib/readline/complete.c - broke the code that actually displays a list of completion matches on the output stream into a separate public function, rl_display_match_list, so it can be called from the hook function rl_completion_display_matches_hook. lib/readline/readline.h - new extern declaration for rl_display_match_list lib/readline/rltech.texinfo - documented rl_display_match_list configure.in,Makefile.in - --enable-static-link now creates a STATIC_LD variable in Makefile rather than adding to LDFLAGS directly. LDFLAGS now includes $(STATIC_LD) 6/2 --- builtins/cd.def - OLDPWD is now auto-exported - broke the code out of bindpwd() that updated the value of PWD in the export environment in-place and made it general, so it can be used for OLDPWD, too (this should be made *more* general, and moved to variables.c) 6/3 --- variables.c - moved builtins/cd.def:export_pwd_var to here, renamed it to update_export_env_inplace - converted put_command_name_into_env to just call update_export_env_inplace - made dummy variable for OLDPWD, marked as invisible and exported, in initialize_shell_variables variables.h - extern declaration for update_export_env_inplace builtins/cd.def - changed calls to export_pwd_var to update_export_env_inplace lib/readline/bind.c - added missing return in rl_unbind_function_in_map - changed _rl_read_file to check whether or not `read' returns < 0 rather than < file_size - _rl_read_init_file needs to free `openname' after calling _rl_read_file, since it's not used again lib/readline/callback.c - bogus extern declaration for `readline_internal_startup', should be readline_internal_setup lib/readline/histfile.c - read_history_range now checks whether read(2) returns < 0 rather than checking the return value against the file size lib/readline/parens.c - whoops -- timer.tv_usec is *micro* seconds, not milliseconds lib/readline/readline.c - initialize `eof' to 1 in readline_internal_charloop 6/5 --- configure.in - if we're configuring with an installed version of readline, set and have configure substitute RL_INCLUDE to `-I$(includedir)', so the build process uses the installed readline include files as well as the libraries Makefile.in, builtins/Makefile.in - add @RL_INCLUDE@ in the appropriate places, substituted by configure lib/readline/{history,readline}.h - add `extern "C"' wrapper if `__cplusplus' is defined lib/glob/fnmatch.h - include stdc.h - add prototypes to extern declaration for fnmatch() lib/readline/rlstdc.h - link to ../posixheaders/stdc.h (in readline lib with different name for benefit of standalone readline library installation) lib/readline/{history,keymaps}.h - include rlstdc.h - add prototypes to all of the extern function declarations lib/readline/history.h - the `data' member of a HIST_ENTRY is now a histdata_t, which is either a void * (ansi c) or a char * (k&r c) lib/readline/readline.c - changed calls to replace_history_entry to pass a histdata_t as the third parameter 6/8 --- copy_cmd.c - make sure that copy_cond_command doesn't blindly try to copy com->op, since that will be null for AND and OR nodes, at least [in bash-2.02.1] lib/readline/vi_mode.c - added missing second argument to rl_vi_[fbe][Ww]ord(), since they're used as pseudo-bindable commands (they appear in the default funmap) as well as utility functions lib/readline/readline.h - include rlstdc.h - added prototypes for functions from vi_mode.c, util.c, terminal.c, search.c, util.c, undo.c, readline.c, parens.c, macro.c, kill.c, keymaps.c, isearch.c, input.c, funmap.c, display.c, complete.c, callback.c, - added extern declarations for functions from rltty.c lib/readline/{readline,util}.c - rl_refresh_line now takes the standard two arguments for bindable commands; changed callers lib/readline/*.c - small cleanups for incorrect arguments, etc. uncovered by use of function prototypes bashline.c - small cleanups for incorrect arguments, etc. uncovered by use of function prototypes 6/11 ---- jobs.c - cast result of strsignal() to (char *) for the benefit of broken Cray UNICOS machines [in bash-2.02.1] configure.in,aclocal.m4 - new test, BASH_TYPE_BITS64_T, used to find out what basic type is 64 bits long; defaults to `double' - call AC_CHECK_SIZEOF(double) config.h.in - #define for bits64_t, undef by default 6/24 ---- aclocal.m4 - changed BASH_TYPE_BITS64_T so that it checks the size of a char * first, before trying sizeof(double) lib/readline/doc/rluser.texinfo,doc/{bash.1,readline.3} - changed default binding for tilde-expand to M-&, since bash overrides M-~ to force username completion bashline.c - fixed an off-by-one error in hostnames_matching that exhibited itself when an exact multiple of 16 hostnames matched (fix from ) [in bash-2.02.1] 6/30 ---- lib/readline/readline.c - the maximum numeric argument is now 1000000 bashline.c - fixed a bug in bash_directory_completion_hook that caused memory to be freed twice if a directory name containing an unset variable was completed and `set -u' had been set configure.in - on LynxOS, add a -DRECYCLES_PIDS to LOCAL_CFLAGS execute_cmd.c - make sure that the changes to make the shell fork early when run in the background do not cause commands such as `%1 &' to fork [in bash-2.02.1] - if RECYCLES_PIDS is defined, execute_command_internal sets last_made_pid to NO_PID after waiting for a foreground process, if the return status is 0 (fix from plai@Lynx.COM (Paul Lai)) lib/readline/kill.c - fixes from Andreas Schwab to rl_yank_last_arg that make it behave better lib/readline/input.c - fixes from Donald Beaudry to make the input buffering and rl_stuff_char work right when the input buffer is nearly full (probably not a problem with keyboard input, but maybe a problem with programmers attempting to use rl_stuff_char to preload the input buffer) 7/14 ---- parse.y - fix to decode_prompt_string so that the \$ expansion quotes the `$' so it won't be processed by subsequent parameter expansion - change read_token_word so a $$ appearing in a token is recognized and parsed immediately, so a single or double quote after the second `$' doesn't cause ANSI-C expansion or locale translation (bug report from haertel@ichips.intel.com) 7/16 ---- lib/readline/display.c - fixed a bug that caused core dumps in xrealloc if the prompt was longer than 1024 characters 7/21 ---- builtins/mkbuiltins.c - if the number of characters read from the .def file is less than the file size reported by `stat', and the read completed without errors, reset the file size to avoid writing garbage at the end of the generated .c file (needed on WIN32 systems, doesn't hurt on Unix) 7/22 ---- CWRU/empty-for-wordlist - patch from Brian Fox for parse.y to allow bash to accept an empty `wordlist' after the `in' keyword in a for statement 7/23 ---- doc/bash.1 - corrected the synopsis of the `for' and `select' statements to indicate that the semicolon (or newline) after the optional `in words' is required [bash-2.02.1 released] 7/28 ---- lib/readline/display.c - make sure visible_length is initialized to 0 in rl_expand_prompt. Fix from Gerhard Niklasch . lib/glob/glob.c - make sure that quotes are removed from the filename being globbed in glob_vector() before calling the GLOB_TESTNAME macro if there are no globbing characters in the pattern doc/Makefile.in - make sure that builtins.1 is looked for in $(srcdir) when running `make install' (it's still commented out, though) 7/30 ---- config.h.bot - if PROMPT_STRING_DECODE is not defined, define PPROMPT (the primary prompt string) as "$ " variables.c - if PROMPT_STRING_DECODE is not defined, and current_user.euid == 0, PS1 defaults to "# ", otherwise it defaults to `primary_prompt' doc/bashbug.1 - fixed email address prep.ai.mit.edu -> gnu.org 8/3 --- support/shobj-conf - add `solaris2' as a possible OS name, treated the same as sunos5 8/4 --- shell.c - changed maybe_make_restricted() so that $ENV and $BASH_ENV are read-only variables in a restricted shell doc/{bash.1,bashref.texi} - added ENV and BASH_ENV to the list of readonly variables in restricted mode parse.y - added `do', `then', `else', `{', and `(' to the list of keywords that may precede the `time' reserved word general.c - added sanity checks to timeval_to_secs and clock_t_to_secs so that if the fractional part is >= 1000, 1 is added to the seconds and 1000 is subtracted from the fractional seconds 8/6 --- Makefile.in - use $(CC_FOR_BUILD) to build mksignames configure.in - changes to allow cross-building for BeOS as well as cygwin32 cross-build/{beos-sig.h,x86-beos.cache} - new files for cross-compiling for BeOS 8/7 --- Makefile.in - changed rule for version.h to use && instead of if-then-else-fi to make sure the recipe fails if mkversion.sh fails configure.in - beos does not use the GNU malloc lib/sh/itos.c - broke itos into inttostr(i, buf, len) and itos(i), which calls inttostr and returns a newly-allocated string with the result support/mksignames.c - define `SIGKILLTHR' if system include files define it externs.h - extern declaration for inttostr(int, char *, int) 8/13 ---- lib/sh/strtol.c - include stdc.h before bashansi.h execute_cmd.c - make sure that execute_cond_node treats `=' the same as `==' 8/25 ---- variables.c, print_cmd.c - changed some calls to itos to use inttostr instead cross-build/x86-beos.cache, {execute_cmd,general,shell,trap}.c - some changes for BeOS (from fnf@ninemoons.com) lib/posixheaders/memalloc.h - changes to handle case where we're using both gcc and the C version of alloca(), or if we have alloca.h and we're using the C version of alloca() (from fnf@ninemoons.com) lib/sh/oslib.c - if bcopy or bzero are #defines, #undef them before defining replacement functions support/config.guess - recognize AmigaOS (from fnf@ninemoons.com) - recognize BeOS running on various machines (from fnf@ninemoons.com) support/config.sub - change basic_machine definition for amiga; added amigaos (from fnf@ninemoons.com) - changed definitions for MIPS machines running Linux (from fnf@ninemoons.com) - recognize `beos' as a valid operating system (from fnf@ninemoons.com) - changed OS for *-cbm to `amigaos' rather than `amigados' (from fnf@ninemoons.com) examples/functions/autoload.v3 - a new version, from Mark Kennedy lib/readline/readline.c - new function, rl_delete_or_show_completions, like tcsh editing function delete-char-or-list lib/readline/readline.h - new extern declaration for rl_delete_or_show_completions lib/readline/funmap.c - new bindable name `delete-char-or-list', like tcsh lib/readline/doc/rluser.texinfo, doc/{bash.1,readline.3} - documented new delete-char-or-list command general.c - fix full_pathname to keep it from generating things like //foo when the current directory is / 8/27 ---- builtins/fc.def - fixed the help text for the -e option 8/28 ---- support/shobj-conf - added a clause for AIX 4.2 systems running gcc -- just the standard gcc stuff for shared objects, but it has to come before the other AIX 4.2 clause 8/31 ---- shell.c - some changes so that `set -e' is turned off while executing the startup files 9/3 --- flags.c - new variable, `restricted_shell', non-zero if the shell was started in restricted mode flags.h - extern declaration for restricted_shell shell.c - new function, shell_is_restricted, returns 1 if the shell is supposed to be restricted based on the basename of $0 or the -r option - set restricted_shell to the value returned by shell_is_restricted before executing the startup files externs.h - extern declaration for shell_is_restricted builtins/shopt.def - new shopt variable, restricted_shell, indicates whether the shell was restricted at startup -- useful in startup files doc/{bash.1,bashref.texi} - documented new restricted_shell shopt option 9/15 ---- lib/sh/rename.c - new file, replacement for rename(2) if the OS doesn't provide it configure.in,config.h.in,Makefile.in,lib/sh/Makefile.in - machinery for including rename.o in libsh.a nojobs.c - make sure that set_tty_state returns a value builtins/mkbuiltins.c - use a call to rename(2) instead of a link/unlink pair lib/glob/glob.c - don't #define bcopy if bcopy is already defined lib/readline/histfile.c - add a call to ftruncate for BeOS, which ignores the O_TRUNC flag to open lib/readline/input.c - make rl_getc loop if read returns -1/EINTR on BeOS configure.in - set ARFLAGS and substitute it into the Makefiles {,builtins,lib/{glob,malloc,readline,sh,termcap,tilde}}/Makefile.in - ARFLAGS is now substituted by configure - use ARFLAGS in rules that create libraries using $(AR) builtins/printf.def - fixed bug that caused a core dump when a modifier was supplied in the format string without a conversion character (e.g. `%h') 9/17 ---- lib/glob/glob.c - if filenames starting with a dot don't have to be matched explicitly (e.g., after a `shopt -s dotglob'), don't match `.' or `..' in any case eval.c - make sure that array assignments don't show up in the history list (fix from Andreas Schwab ) lib/readline/complete.c - fix to rl_menu_complete so it inserts a single completion properly when a word matches only one filename 9/24 ---- execute_cmd.c - difftimeval should zero out the tv_usec field if the tv_sec field is < 0 - addtimeval should check for tv_usec being == 1000000 and add one to tv_sec if it is 9/25 ---- subst.c - fix to expand_word_internal to prevent non-whitespace IFS characters from causing word splitting if they are not the results of an expansion (not exactly right yet, but I think it's the result of a problem with the ${...} end-brace-matching code in the parser) 9/28 ---- parse.y - new flag for parse_matched_pair -- P_FIRSTCLOSE -- which makes it not count and match additional construct open characters - change calls to parse_matched_pair when matching braces in ${...} constructs (both unquoted and within double quotes) to specify the P_FIRSTCLOSE flag to match POSIX.2 requirements subst.c - changed fix from 9/25, now that the parser problem is fixed 9/30 ---- variables.c - change expansion of list of words between (...) in array assignments to include pathname generation in assign_array_var_from_string doc/{bash.1,bashref.texi} - clarified behavior of the shell at startup if running setuid, with and without the -p option supplied 10/7 ---- bashhist.c - change default open(2) mode to 0600 instead of 0666 for `privacy concerns' 10/13 ----- lib/readline/display.c - fixed a problem with displaying tabs after newlines, from - in update_line, if we are printing over existing material, only call space_to_eol or _rl_clear_to_eol if lendiff is non-zero - when moving the cursor in _rl_move_cursor_relative, only call _rl_backspace if the current cursor position is strictly greater than the desired cursor position 10/14 ----- locale.c - LC_ALL is no longer set automatically when LANG is assigned a value config.h.{top,bot} - renamed to config-{top,bot}.h, respectively config.h.in - include config-top.h and config-bot.h Makefile.in - things now depend on config-top.h and config-bot.h subst.c - minor changes to extract_dollar_brace_string and char_is_quoted to allow things like "${PIP[TAB] to perform correct variable completion 10/15 ----- builtins/Makefile.in - add $(PROFILE_FLAGS) to the make recipe that creates `mkbuiltins', so configuring with --enable-profiling works right 10/20 ----- doc/bashref.texi - documented the new --with-installed-readline option [bash-2.03-alpha1 frozen] 10/21 ----- builtins/reserved.def - fixed help text for { ... } to make it clear that a semicolon is required before the closing brace 10/22 ----- trap.c - in decode_signal, don't bother calling strcasecmp if signal_names[sig] is null or empty 11/2 ---- configure.in - make sure RL_LIBDIR and HIST_LIBDIR are assigned values even if readline or history is configured out of the shell, so the -L options have arguments in the link command test.c - make test_syntax_error cause test to return a status > 1, to conform to POSIX.2 4.62.8 doc/readline.3 - make sure the SYNOPSIS section indicates that programmers should include before 11/9 ---- Makefile.in - install with explicit mode of 0755 11/10 ----- builtins/test.def - make sure that a missing `]' makes `[' exit with status 2, to conform to POSIX.2 4.62.8 command.h - new word flag: W_NOGLOB, meaning to not perform globbing execute_cmd.c - fix_assignment_statements now turns on the W_NOGLOB flag for arguments to `assignment builtins' that have W_ASSIGNMENT set subst.c - expand_word_internal needs to preserve the W_NOGLOB flag from the word being expanded to the word being returned - glob_expand_word_list does not call shell_glob_filename for a word with W_NOGLOB set builtins/shopt.def - print_shopt is now void configure.in - machines running Rhapsody don't use the bash malloc - pass host_vendor to the Makefiles with AC_SUBST support/config.guess - Rhapsody is really rhapsody, not nextstep support/config.sub - add rhapsody to the list of supported configurations Makefile.in - pass CONF_HOSTTYPE, CONF_OSTYPE, and CONF_MACHTYPE as -D options in SYSTEM_FLAGS, to indicate that they came from the configuration process - set VENDOR variable from host_vendor configuration variable - pass CONF_VENDOR as part of SYSTEM_FLAGS variables.c - define HOSTTYPE, OSTYPE, and MACHTYPE as CONF_HOSTTYPE, CONF_OSTYPE, and CONF_MACHTYPE, respectively 11/11 ----- doc/{bashref.texi,bash.1} - updated description of `read' to clarify the -r option and its effect on backslash escaping 11/13 ----- examples/loadables/{ln,unlink}.c - new loadable builtins 11/23 ----- lib/glob/fnmatch.c - some fixes to handle extended glob patterns immediately following a `*' tests/extglob.tests - updated with cases from bug report fixed today support/shobj-conf - udpated stanza for aix 4.2 with gcc, based on information from jik@cisco.com configure.in - changes to add the correct linker options to allow dynamic linking when using gcc on AIX 4.2, instead of insisting on the AIX C compiler examples/misc/aliasconv.{bash,sh} - changes to handle aliases with embedded single quotes 11/25 ----- lib/readline/complete.c - postprocess_matches should call compute_lcd_of_matches with an argument of `t' instead of `text' - postprocess_matches should never call ding(); leave that for the callers - postprocess_matches no longer needs `text' as the first argument - rl_complete_internal needs to call ding() if postprocess_matches returns 0, since postprocess_matches no longer does it - rl_complete_internal can now free `text' immediately after calling gen_completion_matches, since it's no longer used 11/30 ----- print_cmd.c - make sure redirections following compound commands have a space separating them from the command 12/1 ---- general.c - changed canonicalize_pathname so that if the result path begins with `//', it will be changed to `/' if and only if the original path did not begin with `//' (there has to be a non-slash after the leading `///' in the original path) 12/2 ---- builtins/evalstring.c - augment the test for turning on CMD_NO_FORK to make sure that parse_and_execute_level == 1. That takes care of things like bash -c 'for f in 1 2 3; do eval "/bin/echo \"$f\"" ; done' only printing one line of output 12/8 ---- config-top.h - add commented-out #define for NON_INTERACTIVE_LOGIN_SHELLS so that users may, if they choose, make things like #! /bin/bash --login work in shell scripts 12/10 ----- jobs.c - changes to the way jobs are reaped when the shell is not interactive: o notify_of_job_status no longer marks dead jobs as notified if they did not exit due to a signal; o changed mark_background_jobs_as_notified to take an argument `force': if zero, we only mark enough dead jobs as notified to keep CHILD_MAX jobs in the jobs list, as POSIX.2 specifies. If non-zero, mark all dead jobs as notified; o wait_for_background_pids marks all dead jobs as notified when it has finished waiting for everything, since the only thing that calls it is the `wait' builtin; o wait_for_single_pid marks a job as notified after it has completed, since the only things that call it are wait_for_background_pids and the `wait' builtin o wait_for_job marks the job as notified after the last pid completes execute_cmd.c - change execute_subshell_builtin_or_function to check subshell_environment and pipe_out to decide whether or not to fork if builtin == jobs_builtin, since the early-forking code added in bash-2.02 means that the piping has probably already been done 12/15 ----- parse.y - changes to make avar=((...)) a syntax error instead of ignoring the nested parens and treating it as an array assignment shell.c - changed run_startup_files so that any shell, whether or not it is interactive, will run the login shell startup files when given the --login option. This happens only when not in posix mode. builtins/enable.def - changes to handle Tenon's MachTen, whose dlclose() does not return a value lib/glob/fnmatch.c - changed gmatch so that when it calls extmatch, it removes FNM_PERIOD from the flags if it's not matching at the start of the string. This fixes the problem of `@' and `+' extended-glob subpatterns containing bracket expressions treating `.' specially when matching a portion of the string starting with `.' config-top.h - removed define for NON_INTERACTIVE_LOGIN_SHELLS, since it's no longer necessary 12/17 ----- lib/readline/complete.c - change rl_complete_internal and rl_menu_complete to check rl_filename_completion_desired to decide whether or not we're completing filenames instead of checking whether the attempted completion function is filename_completion_function. filename_completion_function sets rl_filename_completion_desired, so this shouldn't break anything -- just allow postprocessing of matches for user-supplied filename completion functions that don't call filename_completion_function lib/readline/display.c - new function, _rl_erase_entire_line, which erases the entire line, no matter where the cursor is, and puts the cursor at the beginning of the (newly-empty) line lib/readline/readline.c - new application-level variable, rl_erase_empty_line, which, if non-zero, tells readline to erase the contents of the current line, prompt and all, if the only character typed to an otherwise-blank line is bound to rl_newline. Requested by the Cygnus GDB folks. - change to rl_newline to suppress the call to _rl_update_final if rl_erase_empty_line is non-zero, and rl_point == rl_end == 0, since _rl_update_final calls crlf() - change to readline_internal_charloop to call _rl_erase_entire_line if newline was the only thing typed on an otherwise-empty line lib/readline/readline.h - extern declaration for rl_erase_empty_line lib/readline/doc/rltech.texinfo - documented new rl_erase_empty_line variable 12/18 ----- Makefile.in - changed RELSTATUS to `beta1' [bash-2.03-beta1 frozen] 12/21 ----- doc/{bash.1,bashref.texi} - added description of `test -h'; equivalent to `test -L' 12/22 ----- support/shobj-conf - SHOBJ_LDFLAGS should be those options to ld which are common between building dynamically loadable shared objects and shared libraries - added two new variables: SHOBJ_XLDFLAGS, which are ld options specific to building dynamically loaded shared objects, and SHLIB_LIBS, which are other libraries against which shared libraries should be linked. These are for the benefit of AIX 4.2; other stanzas do not need to be changed. configure.in - add call to AC_SUBST for SHOBJ_XLDFLAGS examples/loadables/Makefile.in - SHOBJ_XLDFLAGS is now substituted by configure - $(SHOBJ_LDFLAGS) -> $(SHOBJ_LDFLAGS) $(SHOBJ_XLDFLAGS) in all recipes that build loadable builtins 12/29 ----- support/config.{guess,sub} - changes for NEC SX4 machines running SUPER-UX (?). Info from Nicholas Clark lib/readline/bind.c - new bindable variable, `isearch-terminators', which is the list of characters that will terminate an incremental search without subsequently executing the character as a command lib/readline/isearch.c - changes to incorporate the new isearch-terminators bindable variable; uses new private readline variable _rl_isearch_terminators (suggested by Brian Fox) doc/{bash.1,readline.3}, lib/readline/doc/rluser.texinfo - documented new `isearch-terminators' settable variable lib/readline/complete.c - new convenience function, free_match_list, called from rl_complete_internal 12/30 ----- aclocal.m4 - changed the calls to AC_MSG_ERROR in the cross-compiling sections to AC_MSG_WARN, since AC_MSG_ERROR can cause configure to abort examples/functions/which - new function, emulation of `which' as it appears in FreeBSD 12/31 ----- lib/readline/readline.c - new bindable function: rl_rubout_or_delete. Does rl_rubout if rl_point is at the end of the line, or rl_delete if not. This is intended to mimic the Motif/Netscape/GNOME behavior of the DEL character, and can be bound to delete to get that behavior lib/readline/readline.h - new extern declaration for rl_rubout_or_delete lib/readline/funmap.c - bound the name `forward-backward-delete-char' to rl_rubout_or_delete (currently not bound to any keys) lib/readline/doc/manvers.texinfo - new file with readline manual version information, to mantain consistent numbering between readline and history manuals lib/readline/doc/{rlman,hist}.texinfo - @include manvers.texinfo for version information - moved the @dircategory and and @direntry directives inside the @ifinfo block - changed copyrights to 1988-1999 doc/Makefile.in, lib/readline/doc/Makefile.in - texi2html is now called with -menu (to handle the texinfo menus) and -monolithic (to include the table of contents in the generated HTML file instead of putting it in a separate file - changed recipes to remove references to TOC html files lib/glob/fnmatch.c - include or as appropriate for strchr() declaration 1/4/1999 -------- print_cmd.c - don't print bare words when printing conditional expressions in print_cond_node, use cprintf("%s", cond->op->word) subst.c - in separate_out_assignments, if VARLIST is non-null on function entry, free it up to clean up after a previous error longjmp 1/5 --- configure.in - make sure the case clause that disables the bash malloc on alpha machines catches things like `alphaev56' as well as `alpha' 1/12 ---- lib/readline/histlib.h - new error message code: NO_PREV_SUBST lib/readline/histexpand.c - handle NO_PREV_SUBST with appropriate error message in hist_error - in history_expand_internal, if the `s' or `&' case results in a null or empty LHS, return NO_PREV_SUBST error.c - new interface: command_error(func, code, e, flags); intended to collect command-related errors in one place - new interface: command_errstr(code); returns a string describing command error CODE error.h - extern declarations for command_error and command_errstr command.h - possible values for CODE in calls to command_error and command_errstr {shell,print_cmd,make_cmd,execute_cmd,dispose_cmd,eval}.c ,builtins/evalstring.c - changed some calls to programming_error to use command_error 1/13 ---- configure.in - if --enable-profiling is specified on a solaris2 machine, don't turn on enable-static-link, since it's very hard to build a static binary on solaris2 and gprof does not (apparently) require it builtins/getopts.def - add calls to sh_getopt_restore_state so the state is restored each time getopts is called. This protects us against the behavior of some mallocs, which causes `nextchar' to be set to garbage in getopt.c when a function is called between calls to getopts 1/14 ---- lib/readline/complete.c - if postprocess_matches returns 0 in rl_complete_internal, reset completion_changed_buffer to 0 before returning, since nothing has been changed 1/20 ---- subst.c - fixed pat_subst so that null patterns with a `#' specifier prefix the string to be substituted on with the replacement, and null patterns with a `%' specifier append the replacement to the string to be substituted on doc/{bash.1,bashref.texi} - corrected a small error in the description of parameter pattern substitution support/mksignames.c - SIGINFO means something else on sequent systems 1/26 ---- execute_cmd.c - fix to execute_simple_command to keep a child process from getting a bad value of last_asynchronous_pid when the shell forks early 2/1 --- Makefile.in - changed RELSTATUS to `beta2' 2/2 --- [bash-2.03-beta2 released] 2/3 --- tests/{cprint.{tests,right},run-cprint} - new test to exercise the command printing and copying code -- hopefully this will avoid things like the `conditional commands in functions make the shell abort' problem 2/4 --- version.c - if MACHTYPE is not defined, use CONF_MACHTYPE if it's defined 2/5 --- builtins/read.def - if READLINE is defined, we need an extra pair of braces around the `while' loop that reads from fd 0 if the -e option is supplied, otherwise the code erroneously tests the value of `retval', which is not set when using readline 2/15 ---- builtins/fc.def - make sure that fc closes `stream' before calling fc_execute_file 2/17 ---- builtins/fc.def - don't bother opening and closing the file of commands before calling fc_execute_file, since parse_and_execute will write the commands to the history file for us Makefile.in - changed release status to `release' 2/18 ---- parse.y - change to special_case_tokens so that `time' is not recognized as a reserved word while the parser is parsing a case statement pattern list (if `time' is the first pattern, the last read token will be newline, which time_command_acceptable says is OK to start a pipeline) pathexp.c - some changes to the POSIX_GLOB_LIBRARY code (often unused) shell.c - a couple of changes for Interix (nee OPENNT) - added code that handles systems without a third argument to main(); initializing `env' from `environ', conditionalized on a cpp define NO_MAIN_ENV_ARG configure.in, config.h.in - check for the presence of sbrk(2); define HAVE_SBRK if found xmalloc.c - don't do the space allocated computation when malloc or realloc fails if HAVE_SBRK is not defined configure.in - new configure variable, MAKE_SHELL, defaults to /bin/sh Makefile.in,{builtins,doc,support,lib/{glob,malloc,readline,sh,termcap,tilde},examples/loadables}/Makefile.in - set SHELL from @MAKE_SHELL@ lib/posixheaders/posixjmp.h - Don't override defines for setjmp and longjmp in on Internix (nee OPENNT) lib/readline/complete.c - Interix (OPENNT) doesn't do username completion configure.in - on Interix/OPENNT ($host_os == interix* or opennt*), add -DNO_MAIN_ENV_ARG to LOCAL_CFLAGS - on Interix/OPENNT, set MAKE_SHELL to $OPENNT_ROOT/bin/sh rather than a straight /bin/sh cross-build/opennt.cache - a `configure' cache file for Interix/OPENNT; not necessarily for cross-compiling, but this is where the other system cache files are [bash-2.03 released] 2/19 ---- configure.in - changed OPENNT_ROOT to INTERIX_ROOT for building on Interix support/config.guess - added two stanzas for Interix running on alpha and intel hardware 2/22 ---- config-bot.h - if PROMPT_STRING_DECODE is not defined, #undef PPROMPT before redefining it, to avoid warning messages execute_cmd.c - set jobs_hack in execute_subshell_builtin_or_function only if JOB_CONTROL is defined 2/24 ---- trap.c - fixed an obscure bug caused by a race condition in run_pending_traps. Read the comments in the source code for a full description of the problem and solution 3/1 --- aclocal.m4 - new test, BASH_STRUCT_TIMEVAL, which tries to compile a code fragment that includes and as appropriate and defines HAVE_TIMEVAL if the compile succeeds configure.in - call BASH_STRUCT_TIMEVAL rather than running a pair of AC_HEADER_EGREPs on sys/time.h and time.h lib/readline/histfile.c - include "posixstat.h" rather than - in history_truncate_file, only try to truncate if the history file is a regular file 3/2 --- aclocal.m4 - changed BASH_STRUCT_TIMEVAL back to using a pair of AC_EGREP_HEADERs instead of compiling a program fragment lib/readline/readline.c - readline_internal_charloop should cast the first argument to _rl_dispatch to `unsigned char' to avoid problems with negative array indices on systems where signed chars are the default lib/readline/kill.c - instead of doing a sequence of next_history() calls in rl_yank_nth_arg_internal, save and restore the history position explicitly after finding the correct entry. This attempts to ensure that rl_yank_nth_arg leaves the history pointer set to the same position as when it was called. Fix from Vasco Pedro 3/5 --- redir.c - broke code that opens file for redirection in do_redirection_internal into a separate function: redir_open(path, flags, mode, ri) general.h - changed STREQN so that it evaluates to 1 (strings are equivalent) if N == 0, to match the behavior of strncmp lib/sh/zwrite.c - new file, zwrite() from builtins/evalstring.c builtins/evalstring.c - removed private definition of zwrite builtins/common.c - double_quote needs to protect newlines with backslashes as well - new function, un_double_quote, to remove backslashes proctecting characters that are special in double quotes builtins/common.h - new extern declaration for un_double_quote parse.y - changed read_token_word to requote the expanded value of $'...' using single_quote - added a new flag to parse_matched_pair: P_ALLOWESC. It allows backslashes to quote embedded single quotes, and is used by the $'...' translation code for better ksh93-compatibility - changed localeexpand to call mk_msgstr on the string passed before displaying it if all we're doing is displaying translatable strings in `po' format. mk_msgstr quotes backslashes and double quotes in the string passed with backslashes, and encloses the result in double quotes. If only -D is supplied, the string is not changed at all -- this is what ksh93 does lib/readline/rlconf.h - removed PAREN_MATCHING #define, paren matching is always compiled into readline lib/readline/parens.c - removed code that was active if PAREN_MATCHING was not defined - added _rl_enable_paren_matching, which is called when the readline variable `blink-matching-paren' is assigned a value and changes the appropriate key bindings in emacs_standard_keymap lib/readline/bind.c - no more PAREN_MATCHING defines, `blink-matching-paren' is always available - if `blink-matching-paren' is assigned a value, call _rl_enable_paren_matching (rl_blink_matching_paren) lib/readline/emacs_keymap.c - removed PAREN_MATCHING defines; the default key bindings for ), ], and } are self-insert 3/7 --- stringlib.c - added an extra argument to ansicstr so that `echo -e' will not convert \' to ' externs.h - changed extern declaration for ansicstr parse.y, builtins/{echo,printf}.def - changed calls to ansicstr() appropriately eval.c - in parse_string_to_word_list, if an unexpected token is encountered that causes the string to not parse to a simple command, or to completely consume the string, display an error message and jump back to the top level after restoring the parsing environment, returning an error status from the attempted assignment 3/8 --- lib/glob/fnmatch.c - fixed patscan and extmatch to handle embedded [...](...) patterns better tests/{extglob2.{tests,right},run-extglob2} - an additional set of ksh extended globbing tests, cribbed from zsh 3/10 ---- general.c - changed unset_nodelay_mode slightly to make sure it handles both O_NDELAY and O_NONBLOCK if they have different values; it now returns a value of 0 on success (or no action); -1 on failure general.h - changed extern declaration for unset_nodelay_mode lib/readline/shell.c - new function: unset_nodelay_mode; identical to definition in general.c lib/readline/input.c - changed rl_getc to call unset_nodelay_mode if the read fails with errno == EWOULDBLOCK || errno == EAGAIN 3/11 ---- lib/termcap/termcap.c - minor changes from termutils-2.0 - minor change to MS-DOS version of valid_filename_p so MS-DOS-specific code from tgetent() can be removed (from Michel@smr.nl) lib/readline/bind.c - in _rl_read_file, null-terminate the buffer at the number of characters actually read, not what stat() says the file size is - use ~/_inputrc as a last-ditch inputrc filename on MS-DOS lib/readline/complete.c - change printable_part to handle MS-DOS `drive-letter:' pathname prefixes - removed __GO32__ code, since it's for DJGPP 1.x, which is not supported any more, and they don't work for DJGPP 2.x - added code to support MS-DOS drive letter prefixes and //X/... to filename_completion_function - _rl_completion_case_fold defaults to 1 on MS-DOS lib/readline/{display,input,readline,rltty,signals,terminal}.c - removed __GO32__ code lib/readline/histfile.c - make read_history_range and history_truncate_file work with the actual number of characters read from the file, not the file size as reported by stat() lib/readline/readline.c - change bind_arrow_keys_internal to bind MS-DOS arrow keys to the appropriate functions if __MSDOS__ is defined lib/readline/rltty.c - make sure set_winsize is always defined, with a null body if TIOCGWINSZ is not defined lib/readline/shell.c - include , since this file uses sprintf support/shobj-conf - MS-DOS does not support shared objects lib/tilde/tilde.c - change tilde_find_suffix and isolate_tilde_prefix to understand backslash as a pathname separator on MS-DOS 3/12 ---- lib/readline/{bind,readline,terminal}.c - no longer need to include lib/readline/terminal.c - don't need to include builtins/history.def - broke the code than handles deleting a particular history entry from the history list out into a separate function: delete_histent - added `-d offset' option to delete the history entry at position OFFSET, as displayed when the history is listed jobs.c, nojobs.c - new function, count_all_jobs(), returns the number of active jobs in the jobs list jobs.h - extern declaration for count_all_jobs() configure.in - check for C library function ttyname() config.h.in - define HAVE_TTYNAME if configure finds ttyname(3) parse.y - two new escape sequences for decode_prompt_string: \j number of active jobs in jobs list \l basename of shell's tty device name doc/{bash.1,bashref.texi}, lib/readline/doc/hsuser.texi - documented new `history -d' option - documented new \j and \l prompt string expansion sequences lib/readline/bind.c - new static state variable, currently_reading_init_file, set to 1 while _rl_read_init_file is operating on a file - changed _rl_init_file_error to include the name and line number from the init file only if currently_reading_init_file is non-zero (this is needed since applications like bash can call rl_parse_and_bind, and error messages from those calls would be misleading if they referred to the last inputrc file read bashline.c - support for a `extended command keymap', which will allow readline key sequences to be bound to unix commands using an auxiliary keymap and a special function that knows how to execute commands from it - bind_keyseq_to_unix_command supports `bind -x' - bash_execute_unix_command is the readline callback that looks in an auxiliary keymap to find the shell command to execute for a particular key sequence - new variable, no_empty_command_completion, which suppresses $PATH searching for command completion when TAB is typed on an empty line bashline.h - extern declaration for new function bind_keyseq_to_unix_command builtins/bind.def - added `-x' option to bind a key sequence to a shell command builtins/help.def - added `-s' option to just print a builtin's short_doc builtins/shopt.def - added new shell option, no_empty_cmd_completion', mirroring value of no_empty_command_completion doc/{bash.1,bashref.texi} - documented new `bind -x' option - documented new shopt `no_empty_cmd_completion' option - documented new `help -s' option Makefile.in - changed RELSTATUS to `devel' _distribution - changed to `2.04' 3/15 ---- support/shobj-conf - add `-h $@' to linking options on Solaris 2 with gcc expr.c - changes to add {pre,post}-{inc,dec}rement operators (++id, --id, id++, id--). These are somewhat more liberal than ksh93, and may require more strict syntax checking down the line tests/arith.{tests,right} - additional tests for {pre,post}-{inc,dec}rement operators 3/16 ---- command.h - structures and types for ksh-93-style arithmetic `for' command configure.in - new `--enable-arith-for-command' option to compile arithmetic for command code into the shell config.h.in - new define, ARITH_FOR_COMMAND, turned on by configure parse.y - changed read_token_word to parse a set of arithmetic for expressions between (( and )) as long as the last token read before the `((' was FOR - added grammar rules to build arithmetic for commands make_cmd.c - functions to parse (( ... )) into the three sub-expressions needed for the arithmetic for command and create the command structures (done this way instead of in the grammar rules to avoid forcing users to quote special characters between the (( and )) ) make_cmd.h - extern declaration for make_arith_for_command copy_cmd.c - code to copy arithmetic for commands dispose_cmd.c - code to dispose of arithmetic for commands print_cmd.c - code to print arithmetic for commands execute_cmd.c - code to execute arithmetic for commands and note that they are shell control structures for the piping code doc/{bash.1,bashref.texi} - documented new arithmetic for command doc/bashref.texi - documented new configure --enable-arith-for-command option 3/17 ---- builtins/read.def - added `-t timeout' option and code to support it 3/18 ---- examples/loadables/Makefile.in - various clean targets need to descend into perl examples/loadables/perl/Makefile.in - added mostlyclean and maintainer-clean targets include - new directory, with files from lib/posixheaders lib/posixheaders - removed {posixwait,unionwait,maxpath}.h - moved from top src directory to include subdir Makefile.in,builtins/Makefile.in,lib/{glob,malloc,sh,tilde}/Makefile.in - updated dependencies and file lists for new include directory - added BASHINCDIR variable, added -I${BASHINCDIR} to cc's include path MANIFEST,support/SYMLINKS - updated for new include directory lib/readline/{ansi_stdlib,posixdir,posixjmp,posixstat,rlstdc}.h - changed symlinks to point to ../../include rather than ../posixheaders builtins/common.h - changed `#include "../stdc.h"' to `#include "stdc.h"' builtins/{cd,exec,fc,history,pushd,source,type,umask,printf}.def builtins/{mkbuiltins,common,evalfile,evalstring,getopt}.c - changed include specifications: ../posixstat.h -> posixstat.h ../filecntl.h -> filecntl.h ../maxpath.h -> maxpath.h ../memalloc.h -> memalloc.h include/shtty.h - new file, contents of bashtty.h and code from jobs.c that includes the appropriate terminal file lib/sh/shtty.c - new file with some tty manipulation utility functions bashtty.h - removed jobs.c, nojobs.c - include shtty.h instead of bashty.h and other code that includes the correct system-dependent tty include file lib/sh/Makefile.in - added shtty.o as part of libsh.a MANIFEST - added include/shtty.h and lib/sh/shtty.c, removed bashtty.h 3/19 ---- lib/readline/display.c - some more __MSDOS__ code to make readline work better with DJGPP: output \r instead of tputs(term_cr, ...) lib/readline/terminal.c - some changes for __DJGPP__ (one is of dubious value -- doesn't DJGPP have a termcap library?) 3/23 ---- configure.in - make sure that the $CC argument to shobj-conf is quoted support/shobj-conf - changes to SGI SHOBJ_LDFLAGS from David Kaelbling 3/24 ---- lib/sh/zread.c - interface to read(2) that restarts automatically if errno == EINTR externs.h - new declarations for functions in lib/sh/{zread,zwrite}.c lib/sh/Makefile.in, Makefile.in - add zread.c, zread.o to appropriate file lists {subst,input}.c, builtins/{evalstring.c,read.def} - converted some loops around read() to call zread() instead lib/readline/rltty.h - new struct _rl_tty_chars to save tty special characters lib/readline/rltty.c - new function save_tty_chars to save tty special characters (currently they're only saved -- nothing looks at them yet) - two new internal library functions, _rl_disable_tty_signals () and _rl_restore_tty_signals (), intended to disable tty driver signal processing for readline's literal-next code, so users can do stuff like ^V^C and have ^C end up in the readline buffer even if ^C is the terminal's interrupt character lib/readline/readline.c - changed rl_quoted_insert to disable and restore tty signal handling around the call to rl_read_key (), so users can put tty special chars into the readline buffer 3/25 ---- expr.c - added `,' operator (expr1 , expr2) -- both expr1 and expr2 are evaluated and the return value is the value of expr2. Precedence is higher than assignment (which makes it highest) - make `lasttp' (pointer to last token) part of the expression context that is saved and restored by {push,pop}_context. This is used only in error reporting doc/{bash.1,bashref.texi} - documented new `,' arithmetic operator - cleaned up some of the language concerning variables referenced by name within an arithmetic expression lib/readline/readline.c - new application-settable variable, rl_num_chars_to_read, which, if set to a non-zero value, causes readline to return after reading that many characters (or at least that many characters, if rl_startup_hook is used to prime the input buffer) rather than when reading a character bound to accept-line lib/readline/readline.h - extern declaration for rl_num_chars_to_read builtins/read.def - added new `-n nchars' option to read NCHARS from stdin rather than a complete line. Works both with and without using readline doc/{bash.1,builtins.texi} - documented new `read -n nchars' option 3/26 ---- execute_cmd.c - make sure all uses of PIDs are of type pid_t redir.c - broke stdin_redirects into two functions: stdin_redirection, which checks a single redirection specification, and a new stdin_redirects, which does what it did before but calls stdin_redirection for each redirection in the chain 3/29 ---- aclocal.m4 - new test, BASH_CHECK_DEV_STDIN, checks for /dev/stdin. If it's present HAVE_DEV_STDIN is defined and it's assumed that /dev/stdout and /dev/stderr are present as well configure.in - call BASH_CHECK_DEV_STDIN config.h.in - add HAVE_DEV_STDIN, initially undefined test.c - add /dev/std{in,out,err} to the special filenames that are handled by test_stat() if HAVE_DEV_STDIN is not defined doc/{bash.1,bashref.texi} - documented conditional expressions' handling of /dev/std{in,out,err} stringlib.c - new function, find_string_in_alist, to find (or match as an extended glob pattern) a string in a STRING_INT_ALIST and return the associated token value externs.h - extern declaration for find_string_in_alist redir.c - new STRING_INT_ALIST list of filenames the redirection code handles specially (_redir_special_filenames) - new function, redir_special_open () to handle filenames found in _redir_special_filenames (framework for /dev/tcp and /dev/udp, but those are not implemented get) doc/{bash.1,bashref.texi} - documented special filename handling in redirections 3/30 ---- builtins/read.def - added `-d delim' option, like ksh93, to read until delim rather than newline doc/{bash.1,bashref.texi} - documented new read `-d delim' option configure.in - look for gethostbyname(3), inet_aton(3) - look for and - call BASH_FUNC_GETHOSTBYNAME if gethostbyname(3) is not in libc - check for u_int and u_long types, default to `unsigned int' and `unsigned long' respectively - new enable option `--enable-net-redirections' to compile in the /dev/tcp and /dev/udp redirection code aclocal.m4 - new macro, BASH_FUNC_GETHOSTBYNAME, looks for gethostbyname(3) in the socket libraries if it's not found in libc config.h.in - new defines: HAVE_GETHOSTBYNAME, HAVE_INET_ATON, HAVE_NETDB_H, HAVE_NETINET_IN_H, NETWORK_REDIRECTIONS - new defines: u_int, u_long lib/sh/inet_aton.c - new file, from GNU libc, slightly modified to remove inet_addr() lib/sh/netopen.c - new file, functions to create tcp/udp network connections. Exports a single function: netopen(pathname) externs.h - extern declaration for netopen() lib/sh/Makefile.in, Makefile.in, MANIFEST - added appropriate references to inet_aton.c and netopen.c config-bot.h - if HAVE_SYS_SOCKET_H, HAVE_GETPEERNAME, and HAVE_NETINET_IN_H are all defined, define HAVE_NETWORK redir.c - call netopen for pathnames of the form /dev/(tcp|udp)/host/port if HAVE_NETWORK is defined; print a warning message otherwise - /dev/tcp and /dev/udp code is only compiled in if NETWORK_REDIRECTIONS is defined 3/31 ---- lib/sh/zread.c - new function, zsyncfd(fd) which syncs the kernel's seek pointer on FD with the last character returned by zreadc() externs.h - extern declaration for zsyncfd builtins/read.def - use zreadc if the input is not unbuffered (this cuts the number of read(2) calls *way* down) - if input is not unbuffered, call zsyncfd before returning to make sure zreadc's buffering doesn't consume too much input 4/1 --- Makefile.in - install bashbug with mode 555 4/2 --- shell.c - make want_pending_command and read_from_stdin global rather than local variables flags.c - change which_set_flags to insert `c' and `s' if the `-c' and `-s' invocation options, respectively, were supplied at shell startup bashline.c - change bash_directory_completion_hook to change the logic for deciding whether or not to parameter expand the directory name -- now we expand only if there's a `$' (still has problems if the user quoted the `$') or a `` pair. Fixes bug reported by chuckjr@sinclair.net. To fix the `$' problem, could possibly check what the user typed with rl_line_buffer and start, end parameters to gen_completion_matches - changed attempt_shell_completion to slightly adjust the logic for deciding whether or not a word is in a command position: if the word being completed has a single opening single or double quote before the command separator, treat it as a candidate for (quoted) command word completion - now that we understand partially-quoted strings as completion candidates, we can do command completion on certain unclosed uses of $(... subst.c - change extract_delimited_string to not return an error for an unclosed construct if DOING_COMPLETION is non-zero 4/5 --- expr.c - fixed `ss=09 ; let ss=10' bug by introducing one-token lookahead after a string token is parsed. If the next token is `=', we don't evaluate the variable's value as an expression, since it's not going to be used variables.h - added new member to struct variable: exportstr -- for the future caching of strings to be placed into the environment - extern declaration for bind_variable_value variables.c - make sure that the `exportstr' member of a struct variable is initialized correctly, and put code in to free it where appropriate (if non-null) - new function, bind_variable_value(VAR, VALUE); make shell variable VAR have value VALUE - make sure var->exportstr is invalidated when a variable or function is assigned a value builtins/declare.def - call bind_variable_value instead of duplicating some of bind_variable inline 4/6 --- variables.h - new macros, VSETATTR and VUNSETATTR to set and clear variable attributes builtins{read,set,setattr,declare}.def,{execute_cmd,expr,shell,subst,variables}.c - change to use VSETATTR and VUNSETATTR 4/7 --- doc/Makefile.in - if htmldir is set by configure, install the html files into that directory with `make install' and remove them with `make uninstall' Makefile.in,doc/Makefile.in - htmldir is set by configure and passed from the Makefile to the install in the doc subdirectory configure.in - substitute `htmldir' into Makefiles support/config.guess - some small changes for Apple's Rhapsody lib/termcap/Makefile.in - make the `distclean' and `maintainer-clean' targets remove Makefile lib/termcap/ltcap.h - new private library include file, for Rhapsody __private_extern__ define lib/termcap/{termcap,tparam}.c - include "ltcap.h" - if HAVE_CONFIG_H is defined, include if HAVE_STDLIB_H is defined, otherwise declare getenv, malloc, realloc as extern - add __private_extern__ qualifier for extern data that Rhapsody requires shell.c - don't run the startup files in the rshd case if shell_level is >= 2 This should catch the case of rsh machine bash -c 'echo a' running the .bashrc twice, once for the shell started by rshd and one for the shell running -c command 4/8 --- variables.c - in initialize_shell_variables, unset the export attribute from SSH_CLIENT if it exists and we got it from the initial environment shell.c - don't bother unsetting export attribute from SSH_CLIENT, since we now do it in initialize_shell_variables lib/readline/display.c - don't check prompt_this_line[-2] in rl_redisplay if prompt_this_line isn't at least 2 characters after the start of rl_display_prompt lib/readline/histfile.c - change the name of the default history file to _history on MS-DOS lib/readline/histlib.h - add an extern declaration for history_offset lib/readline/hist{expand,search}.c - remove extern declaration for history_offset; now in histlib.h lib/readline/xmalloc.h - new file, extern declarations for xmalloc, xrealloc, xfree lib/readline/rlprivate.h - new file, with extern declarations for `readline private' global variables and functions lib/readline/rlshell.h - new file, with extern function declarations for stuff in shell.c lib/readline/Makefile.in - add dependencies on xmalloc.h, rlshell.h - add xmalloc.h, rlprivate.h to list of header files MANIFEST - add lib/readline/xmalloc.h, lib/readline/rlprivate.h, lib/readline/rlshell.h Makefile.in - add $(RL_LIBSRC)/xmalloc, $(RL_LIBSRC)/rlprivate.h, $(RL_LIBSRC)/rlshell.h to READLINE_SOURCE variable lib/readline/{bind,complete,display,funmap,histexpand,histfile,history,input, isearch,keymaps,kill,macro,readline,search,shell,util,vi_mode}.c - include "xmalloc.h" rather than extern declarations for xmalloc, xrealloc, xfree lib/readline/terminal.c - new function, used in two places, _emx_get_screensize for EMX lib/readline/readline.c - EMX apparently no longer needs _emx_build_environ lib/readline/signals.c - support for __EMX__ in rl_signal_handler - don't set the old handler passed to rl_set_sighandler to rl_signal_handler, because that would cause infinite recursion if that signal were generated lib/readline/xmalloc.c - no longer the same as lib/malloc/xmalloc.c, which is no longer used by anyone - changes to include xmalloc.h, define READLINE_LIBRARY, change some of the argument types lib/tilde/tilde.c - add prototypes for extern function declarations if __STDC__ defined lib/readline/{terminal,bind,readline,nls,histexpand}.c - include "rlshell.h" for function prototypes 4/9 --- lib/readline/{bind,callback,complete,display,input,isearch,kill,macro,nls, parens,readline,rltty,search,signals,terminal,util,vi_mode}.c - include "rlprivate.h" - remove extern declarations already in rlprivate.h xmalloc.c - xfree should take a PTR_T as its argument general.h - change prototype for xfree to use void * instead of char * lib/malloc/malloc.c - define PTR_T like it is defined in general.h - malloc() returns a PTR_T - free() takes a PTR_T as its argument - realloc() returns a PTR_T and takes a PTR_T as its first argument - memalign returns a PTR_T - valloc returns a PTR_T - calloc returns a PTR_T - cfree() takes a PTR_T variables.c - new function: char **all_variables_matching_prefix (char *prefix) variables.h - extern declaration for all_variables_matching_prefix bashline.c - converted variable_completion_function to use all_variables_matching_prefix stringlib.c - new function, char **alloc_array(n), allocates an argv-style array of strings with room for N members externs.h - extern declaration for alloc_array 4/13 ---- lib/readline/keymaps.c - include "readline.h" - remove extern function declarations include/stdc.h - break the definition of __P out from a strict __STDC__ block, since __GNUC__ and __cplusplus also indicate that prototypes are available lib/readline/readline.h - adjust conditional declaration of rl_message, since __cplusplus indicates that prototypes are available lib/readline/rlstdc.h - private copy, modified, no longer symlinked to ../../include/stdc.h - __P is defined if __GNUC__ or __cplusplus is defined - removed defines for __STRING, const, inline, signed, volatile, since readline does not use them lib/readline/{search,readline}.c - extern declaration for _rl_free_history_entry with prototypes, since it's not in rlprivate.h lib/readline/history.h - added some missing `extern's in function declarations lib/readline/undo.c - include "rlprivate.h" lib/readline/shell.c - include "rlshell.h" lib/readline/Makefile.in - update dependencies for undo.c, shell.c lib/tilde/tilde.h - add #define for __P if not already defined - use prototypes in extern function declarations with __P() lib/readline/doc/rluserman.texinfo - new file, derived from rlman.texinfo {bashline,findcmd,general,pathexp}.c, builtins/getopts.def - call alloc_array(N) instead of (char **)xmalloc (N * sizeof (char *)) subst.c - added code to implement ksh-93 ${!prefix*} expansion doc/{bash.1,bashref.texi} - documented new ${!prefix*} expansion 4/15 ---- execute_cmd.c - new variable, this_shell_function, points to SHELL_VAR of currently executing shell function variables.c - new dynamic variable, FUNCNAME -- invisible when not executing shell function doc/{bash.1,bashref.texi} - documented new FUNCNAME variable 4/16 ---- support/rlvers.sh - add -T option to specify correct termcap library configure.in - Irix 4.x still needs to link with -lsun if it contains a replacement getpwent function that works with NIS - if we're configuring with an already-installed readline library, call BASH_CHECK_LIB_TERMCAP and pass the resulting $TERMCAP_LIB to support/rlvers.sh lib/readline/readline.c - in rl_forward, if rl_point ends up being < 0, set it to 0 lib/readline/exammples/excallback.c - new callback example code, from `Jeff Solomon ' lib/sh/getcwd.c - define NULL as 0 if not defined by one of the standard include files - cast result of malloc and realloc to (char *) where appropriate variables.c - new functions for use by dynamic variables: null_assign and null_array_assign. Used as assign_func for a particular variable, they cause assignments to that variable to be silently ignored - FUNCNAME and GROUPS are no longer readonly - FUNCNAME changed to use null_assign - GROUPS changed to use null_array_assign. This means that the variable can be unset if desired (like for Oracle startup scripts), but cannot be assigned to doc/{bash.1,bashref.texi} - added text about assignments being silently discarded to descriptions of FUNCNAME and GROUPS - removed text saying that GROUPS is readonly - added standard text about GROUPS being unset and losing its special properties, even if reset command.h - new command type, cm_subshell, actually causes the shell to fork and then executes the command in the SUBSHELL_COM struct parse.y - ( ... ) now creates a command of type cm_subshell, with the same flag CMD_WANT_SUBSHELL as previous make_cmd.c - new function make_subshell_command make_cmd.h - extern declaration for make_subshell_command dispose_cmd.c - code to destroy a SUBSHELL_COM copy_cmd.c - code to duplicate a SUBSHELL_COM print_cmd.c - code to print a SUBSHELL_COM execute_cmd.c - broke the code that handles executing commands in subshells out of execute_command_internal into a new function, execute_in_subshell, with the same arguments - executing a command of type cm_subshell is just a slightly special case, handled in execute_in_subshell 4/18 ---- execute_cmd.c - changed code in execute_command_internal that executes subshell commands to check for command->type == cm_subshell in addition to checking that commmand->flags & CMD_WANT_SUBSHELL is non-zero - changed execute_in_subshell to set the CMD_NO_FORK flag on the command to be executed by a command of type cm_subshell (command->value.Subshell->command), if that command is a simple command (type == cm_simple) or a nested subshell (type == cm_subshell) and is not being timed - changed execute_command_internal to just call and return the value returned by execute_in_subshell if it gets a command of type cm_subshell with flags including CMD_NO_FORK lib/malloc/malloc.c - morecore() should always return through morecore_done, not with a simple `return' 4/20 ---- variables.c - new function, quote_array_assignment_chars, backslash quotes all `[' and `]' before an `=' in a word that's part of the body of a compound array assignment. Needed because we run the list through the globbing code now. Don't bother if `=' does not appear in the string or if the first char is not `[' - call quote_array_assignment_chars from assign_array_var_from_string now eval.c - moved parse_string_to_word_list to parse.y parse.y - moved parse_string_to_word_list here. Much simpler -- no longer tries to parse a command, but just reads tokens using read_token(). Any token but a WORD or ASSIGNMENT_WORD causes a syntax error. Don't have to mess around with saving global_command or calling parse_command, but do need to save and restore the history stuff, so the array assignment doesn't get saved on the history list 4/21 ---- nojobs.c - changed to use functions in lib/sh/shtty.c (tt{get,set}attr) for the terminal attributes - added a `flags' field to struct proc_status, flags are PROC_RUNNING and PROC_NOTIFIED (status has been returned to `wait') - functions check flags & PROC_RUNNING to check whether or not a particular process is still alive; PROC_RUNNING is reset by set_pid_status - new function, mark_dead_jobs_as_notified, same function as the one in jobs.c - cleanup_dead_jobs reaps jobs only if they're dead and not marked as notified - wait_for_background pids marks all pids as notified and reaps them before it returns, since it's called by the `wait' builtin - wait_for_single_pid marks the pid being waited for as notified so its slot can be reclaimed -- it's only called by the `wait' builtin - new function, process_exit_status, to turn what wait(2) takes into an exit status 4/22 ---- nojobs.c - add_pid takes a new second argument, async_p, which is non-zero if the process is in the background - new flag, PROC_ASYNC, set by add_pid - set_pid_status now sets the PROC_NOTIFIED flag if PROC_ASYNC is unset, so foreground jobs get cleaned up right away - changed mark_dead_jobs_as_notified to take a `force' argument; if non-zero, it marks only enough dead jobs to make the number of un-notified dead jobs < CHILD_MAX - new function, reap_dead_jobs, same as in jobs.c execute_cmd.c - don't need separate cases for REAP any more 4/23 ---- builtins/printf.def - new function, tescape, which processes a single backslash escape sequence and returns the number of characters consumed by the argument string (code taken from bexpand) - changed bexpand to call tescape rather than do backslash-escape sequence conversion itself - changed occurrences of `illegal' in error messages to `invalid' - printf no longer calls ansicstr to translate backslash-escape sequences; the mainline printf code now calls tescape whenever it hits a backslash 4/26 ---- subst.c - new variable, garglist, set to list of words to be expanded after leading assignment statements are removed - command_substitute now calls maybe_make_exported_env before making the child process if there are no variable assignments preceding the command currently being expanded, or if the command currently being expanded consists only of variable assignments execute_cmd.c - the `early fork' code in execute_simple_command now calls maybe_make_export_env before forking because execute_disk_command would do that in the vast majority of cases, and this will obviate the need to do it for subsequent commands if the environment does not change 4/27 ---- variables.h - more macros to manipulate the exportstr member of a SHELL_VAR - changed initialize_shell_variables to cache the value from the environment as the initial exportstr for all imported variables - changed make_var_array to use exportstr if it exists, instead of computing the value - changed make_var_array to cache exportstr for exported functions, so they don't have to be deparsed every time the export env is remade 4/28 ---- lib/readline/{histlib,rldefs}.h - changed STREQN macro to evaluate to 1 if the third argument is 0 lib/readline/search.c - changed rl_history_search_{for,back}ward so they leave point at the end of the line when the string to search for is empty, like previous-history and next-history - broke common code out of rl_history_search_{for,back}ward into a new function, rl_history_search_reinit - rewrote rl_history_search_internal to be more like the non-incremental search functions, use noninc_search_from_pos, and leave the last history line found in the current line buffer if the search fails - new function, make_history_line_current, takes care of making the current line buffer a copy of the history entry passed as an argument; used by rl_history_search_internal and noninc_dosearch subst.c - make ${!prefix@} be the same as ${!prefix*} for (undocumented) ksh93 compatibility 4/30 ---- lib/readline/doc/rltech.texinfo - added note about including , and that should be included before readline.h lib/readline/doc/hstech.texinfo - added note about including lib/readline/doc/manvers.texinfo - updated version to 4.1 lib/readline/{bind,complete,display,isearch,nls,parens,readline,signals,tilde, histexpand}.c - added prototypes with __P((...)) for forward static function declarations lib/readline/display.c - broke the code that initializes VISIBLE_LINE and INVISIBLE_LINE out of rl_redisplay into a new function, init_line_structures, which takes an argument giving the minimum number of characters that the line must hold - new function for use by applications that want to display the initial prompt themselves rather than having the first call to readline do it: rl_on_new_line_with_prompt (modified from code in the CLISP distribution) lib/readline/readline.c - new external variable, rl_already_prompted, to let readline know that the prompt string has already been displayed on the screen before the first call to readline - test rl_already_prompted before displaying the prompt in readline_internal_setup - if rl_already_prompted is non-zero, readline_internal_setup calls rl_on_new_line_with_prompt instead of rl_on_new_line lib/readline/readline.h - extern declaration for rl_on_new_line_with_prompt - extern declaration for rl_already_prompted lib/readline/doc/rltech.texinfo - documented rl_on_new_line_with_prompt and rl_already_prompted builtins/read.def - new -s option (silent mode).

All we can do is check shell_input_line and see if the next chars are `in' -- if so, we return " " 9/16 ---- builtins/hash.def - don't allow `hash -p /pathname/with/slashes name' if the shell is restricted doc/{bash.1,bashref.texi} - updated description of restricted shell mode lib/readline/display.c - fixed a bug in _rl_update_final which used the inv_lbreaks array to index into visible_line jobs.c - waitchld() need not go through the pain of setting up an environment to execute traps on SIGCHLD if children_exited == 0 - waitchld returns -1 if waitpid() returns -1 with errno == ECHILD, indicating that there are no unwaited-for child processes, and it has not yet reaped any dead children - wait_for, wait_for_single_pid return -1 if waitchld() returns -1 - new function, mark_all_jobs_as_dead - wait_for_background_pids calls mark_all_jobs_as_dead if wait_for_single_pid returns -1 with errno == ECHILD, since there are no unwaited-for child processes subst.c - tentative change: subshells started for command substitution no longer unconditionally disable job control 9/17 ---- parse.y - new function: save_token_state(). Saves the value of last_read_token and the two previous tokens in an allocated array and returns the array - new function: restore_token_state(ts). TS is an array returned by save_token_state. last_read_token and the two previous tokens are set from the values in TS trap.c - run_pending_traps calls save_token_state and restore_token_state around the call to parse_and_execute, which will call the parser and possibly leave it in a state where reserved words will not be recognized (_run_trap_internal, too) 9/20 ---- support/bashbug.sh - if sendmail is used as $RMAIL, pass `-i -t' as arguments so changes made by the user to the recipient headers in the message are honored 9/21 ---- bashhist.c - if histverify has been set, make sure a `:p' modifier to a history expansion prints the result builtins/echo.def - new extern variable, xpg_echo, set to 1 if DEFAULT_ECHO_TO_USG is defined and 0 otherwise - echo_builtin now sets the initial value of do_v9 from xpg_echo builtins/shopt.def - new shopt option, `xpg_echo', turns backslash escape expansion by `echo' on and off at runtime builtins/{bash.1,bashref.texi} - documented new `xpg_echo' shell option tests/{builtins.tests,builtins2.sub,shopt.tests} - changes for new `xpg_echo' shell option configure.in - changes for FreeBSD-3.x ELF to add `-rdynamic' to LOCAL_LDFLAGS. This allows dynamic loading of builtins support/shobj-conf - changes to handle FreeBSD-3.x elf or a.out object file formats 9/23 ---- [bash-2.04-beta1 released] 9/24 ---- jobs.c - wait_for returns -1 only if the shell is currently executing the `wait' builtin, since that's the only thing that cares execute_cmd.c - moved cases of close_fd_bitmap to before calls to do_piping to handle some pathological cases 9/29 ---- execute_cmd.c - save the command line in execute_simple_command before making the export environment, since maybe_make_export_env clobbers the_printed_command if there are exported functions 9/30 ---- configure.in,config.h.in - check explicitly for setvbuf; define HAVE_SETVBUF if found configure.in - change opt_gnu_malloc to opt_bash_malloc, since the bash malloc is not really the gnu malloc anymore - new argument, --with-bash-malloc, identical to --with-gnu-malloc - AC_DEFINE(USING_BASH_MALLOC) if opt_bash_malloc is enabled config.h.in - new #define for USING_BASH_MALLOC doc/bashref.texi - updated installation section to add --with-bash-malloc and change description of --with-gnu-malloc lib/sh/setlinebuf.c - change name of function to sh_setlinebuf, just returns 0 if HAVE_SETVBUF and HAVE_SETLINEBUF are undefined - prefer setvbuf to setlinebuf if we have both - if we're using setvbuf, use a local buffer for stdin and stdout local buffer is BUFSIZ unless we're using the bash malloc (USING_BASH_MALLOC is defined), in which case it's 1008 (which the bash malloc rounds up to 1024) 10/4 ---- input.c - if USING_BASH_MALLOC is defined, set the max buffer size to 8176, which the bash malloc rounds up to 8192 10/5 ---- pcomplete.c - new function, pcomp_filename_completion_function, a wrapper for filename_completion_function that dequotes the filename first bashline.c - changed bash_directory_completion_matches to dequote the filename before passing it (indirectly) to filename_completion_function execute_cmd.c - change execute_command to defer calling unlink_fifo_list until any shell function has finished executing (variable_context == 0) configure.in - added AC_CYGWIN, AC_MINGW32, AC_EXEEXT 10/8 ---- subst.c - expand_word_internal(): changes some things to avoid small (2 or 3 byte) calls to xmalloc -- added a label and some gotos (BEWARE) - changed make_dev_fd_filename so it doesn't call sprintf anymore 10/27 ----- execute_cmd.c - make execute_select_command handle the effects of the `continue' builtin correctly 11/5 ---- Makefile.in - RELSTATUS changed to `beta2' 11/8 ---- [bash-2.04-beta2 released] 11/9 ---- shell.c - make run_startup_files check for ssh2 as well as ssh1 11/19 ----- parse.y - make sure parsing conditional commands isn't confused by unexpected tokens (like `[[)]]') builtins/common.c - fix get_job_spec to return NO_JOB for numeric job specs that are beyond the size of the jobs table builtins/type.def - change describe_command to report `not found' if a path search returns the same string as the command name and the command name does not match an executable file. This has implications for `type' and `command -[vV]'. - if a command is not found in $PATH, but an executable file with the name supplied exists in the current directory, make the command into a full pathname for the `command' builtin. This has implications for `type' and `command -[vV]' subst.c - new function, expand_prompt_string, expands prompt string and returns the string passed if an error occurs subst.h - extern declaration for expand_prompt_string parse.y - decode_prompt_string calls expand_prompt_string instead of expand_string_unsplit 11/22 ----- builtins/echo.def - return EXECUTION_FAILURE if ferror(stdout) is true 11/23 ----- locale.c - if LC_ALL is unset, call setlocale(LC_ALL, lc_all), because lc_all holds the default locale 11/29 ----- lib/readline/shell.c - define NULL as 0 if it's not defined - change single_quote to allocate 4 characters in new string for each character in the old one (like builtins/common.c:single_quote) locale.c - when a locale variable (LC_*) is unset, pass "" to setlocale() to get the default locale set, since value is NULL lib/sh/makepath.c - new function, sh_makepath(char *path, char *dir, int flags) Makefile.in - changed version to beta3 builtins/type.def - changed describe_command to use sh_makepath() builtins/cd.def - removed private declaration of mkpath(), changed to use sh_makepath general.c - changed make_absolute to use sh_makepath - changed full_pathname to use sh_makepath findcmd.c - removed private definition of make_full_pathname, changed to use sh_makepath doc/{bashref.texi,bash.1} - added text to description of `getopts' to make it clear that getopts may be used to parse option characters other than letters, and that `:' and `?' may not be used as option characters eval.c - when processing a jump_to_top_level(EXITPROG), make sure the shell doesn't think it's still in a function by setting variable_context to 0 doc/rbash.1 - a skeletal man page for rbash, adapted from debian support/bashbug.sh - try to find a default editor if EDITOR is unset, rather than blindly using `emacs' 11/30 ----- support/config.{guess,sub} - many changes from the latest `automake' distribution, from the Debian folks 12/2 ---- lib/readline/keymaps.h, lib/tilde/tilde.h - added support for C++ compilation (`extern "C" {...}') 12/3 ---- subst.c - in process_substitute, make sure the child resets the O_NONBLOCK flag on the file descriptor opened for read to a named pipe jobs.c - new function, raw_job_exit_status, returns exit status of last job in pipeline - change job_exit_status to call raw_job_exit_status and pass the result to process_exit_status - in notify_of_job_status, get termination status from call to raw_job_exit_status, rather than the first job in the pipeline (fixes debian bug #15165) bashhist.c - changed bash_history to not add shell comment lines to the history file (fixes debian bug #21901). Uses new function shell_comment(L) which returns 1 if L is a shell comment line. Doesn't handle comments embedded in lines yet redir.c - when running in POSIX.2 mode, bash no longer performs word splitting on the expanded value of the word supplied as the filename argument to a redirection operator (fixes debian bug #30460) doc/bashref.texi - added new redirection stuff to POSIX Mode section (from previous fix) 12/6 ---- hashlib.h - removed extra semicolon at end of HASH_ENTRIES define redir.c - replaced toggling of disallow_filename_globbing flag with setting flags in redirection word to include W_NOGLOB if the shell is in POSIX mode and not interactive when expanding the filename argument to a redirection 12/7 ---- builtins/common.c - new function, backslash_quote_for_double_quotes(char *), quotes characters special when in double quotes in the string passed as an argument. #ifdef PROMPT_STRING_DECODE; called by decode_prompt_string builtins/common.h - extern declaration for backslash_quote_for_double_quotes parse.y - call backslash_quote_for_double_quotes instead of backslash_quote in decode_prompt_string 12/9 ---- parse.y - before expanding the \u prompt string escape sequence, make sure current_user.user_name is non-null and call get_current_user_info if it is 12/10 ----- support/mkversion.sh - changes to avoid relying on floating point output format, which can be locale-specific 12/14 ----- print_cmd.c - changes to named_function_string (for normal function printing) and print_function_def (for printing function definitions embedded in other commands) to print redirections that should be attached to the function as a whole after the closing brace tests/func1.sub - tests for printing functions with attached redirections, called by func.tests 12/16 ----- lib/readline/complete.c - if we're completing files in the root directory and executing the visible-stats code, don't pass an empty pathname to rl_directory_completion_hook, because, for bash, that will be expanded to the current directory. Just pass `/' instead. lib/tilde/tilde.c - fix to tilde_expand_word for Cygwin to avoid creating pathnames beginning with `//' if $HOME == `/' variables.c - don't bother with the exportstr validation on cygwin systems, or even using exportstr at all, since that system has weird environment variables 12/17 ----- configure.in - new option, --enable-xpg-echo-default, new name for --enable-usg-echo-default (which is still present for backwards compatibility) configure.in, config.h.in, builtins/echo.def - DEFAULT_ECHO_TO_USG -> DEFAULT_ECHO_TO_XPG 12/29 ----- aclocal.m4 - changed a couple of tests to avoid creating files with known names in /tmp support/rlvers.sh - changed to create files in /tmp/rlvers support/mksignames.c - now understands the POSIX.1b real-time signal names on systems that support them 12/30 ----- [bash-2.04-beta3 released] 12/31 ----- redir.c - try some more things to avoid race file replacements in here_document_to_fd parse.y - two new functions: get_current_prompt_level: returns 2 if current prompt is $PS2, 1 otherwise set_current_prompt_level: sets current prompt to $PS2 if arg is 2, $PS1 otherwise copy_cmd.c - make sure to copy the `line' member in copy_arith_for_command pcomplete.c - free up `lwords' and `line' after evaluating any command or shell function in gen_compspec_completions - after filtering any matches specified by cs->filterpat in gen_compspec_completions, free ret->list (the members have already been copied or freed by filter_stringlist) bashline.c - free what find_cmd_name returns after calling the programmable completion code 1/4/2000 -------- subst.c - make call_expand_word_internal set w->word to NULL if either expand_word_error or expand_word_fatal is returned 1/7 --- parse.y - two new functions: set_current_prompt_level(int) and get_current_prompt_level() to set and get the `level' of current_prompt_string (1 if $PS1, 2 if $PS2) externs.h - extern declarations for {get,set}_current_prompt_level builtins/evalstring.c - add an unwind_protect to save and restore the current prompt string pointers using {get,set}_current_prompt_level 1/9 --- Makefile.in - changed release status to `beta4' 1/18 ---- [bash-2.04-beta4 released] 1/19 ---- configure.in - moved checks for non-unix variants to beginning of tests Makefile.in, {builtins,support}/Makefile.in - added some $(EXEEXT) suffixes to generated programs for non-Unix systems 1/20 ---- parse.y - make get_current_prompt_level return 1 if current_prompt_string is NULL (as it would be while sourcing startup files) support/rlvers.sh - rmdir $TDIR in the exit trap - move the exit trap after we successfully create $TDIR 1/21 ---- subst.c - several changes to split_at_delims to make non-whitespace delimiters create separate fields containing those delimiters, like the shell parser does with meta characters. This allows redirection operators, for example, to be treated as separate words by the programmable completion code examples/complete/complete-examples - added new function: _redir_op, which return true if the word passed as an argument contains a redirection operator (just bare-bones for now) - changed set completion function to use _redir_op as an example parse.y - make parse_string_to_word_list save and restore the value of shell_input_line_terminator, since an assignment like COMPREPLY=() inside a shell function called by the programmable completion code can change shell_input_line_terminator out from underneath shell_getc(). shell_getc will set the input line terminator to EOF when it gets EOF from the getter function, and the string getter function returns EOF at EOS. parse_and_execute tests for EOS directly and never gets EOF from shell_getc, so it does not have this problem. 1/24 ---- lib/readline/funmap.c - #define QSFUNC like in complete.c - cast _rl_qsort_string_compare to a QSFUNC * in the call to qsort lib/readline/terminal.c - correct a typo in usage of the __EMX__ preprocessor define - fix a reversed usage of `#if defined (__DJGPP__)' in _rl_control_keypad - remove extern declarations for _rl_in_stream and _rl_out_stream lib/readline/rlprivate.h - add extern declaration for _rl_in_stream, since there's already one for _rl_out_stream builtins/ulimit.def - if bash is using ulimit(2), make sure that getfilesize() returns the value multiplied by 512 to convert it from a number of blocks to a number of bytes 1/25 ---- execute_cmd.c - make sure execute_command_internal sets last_command_exit_value correctly when inverting the return value of a (...) subshell command tests/{run-invert,invert.{tests,right}} - new tests for return value inversion configure.in - compile without bash malloc on m68k-motorola-sysv due to a file descriptor leak in closedir(3) -- the motorola implementation requires that freed memory be readable so it can free the dirent and then look back at it to find the file descriptor expr.c - fix negative exponents in v**e to return an eval error 2/1 --- Makefile.in - changed status to beta5 jobs.c - fixed a problem with checking the wrong process when checking to see whether or not we need to reset the tty state. The old code checked the first process in a pipeline; the new code checks all processes in the pipeline to see whether any of them exited due to a signal or was stopped. If none were signalled or stopped, the code uses the exit status of the last process in the job's pipeline 2/4 --- [bash-2.04-beta5 released] eval.c - call set_current_prompt_level instead of setting prompt_string_pointer directly 2/10 ---- [bash-2.04-beta5 re-released to net] 2/11 ---- sig.c - make sure SIGCHLD is defined in initialize_shell_signals before trying to use it in sigdelset() (DJGPP fix) 2/14 ---- lib/sh/shtty.c - include before - separate tests for ONLCR, ONOCR, ONLRET to cope with systems like DJGPP that don't implement the full POSIX termios option set builtins/psize.sh - set TMPDIR only if it's not already set lib/glob/glob.c - if a system doesn't define _POSIX_SOURCE but has a `struct dirent' without a d_ino member, define REAL_DIR_ENTRY to 1 so all entries are read configure.in - check for header file config.h.in - add HAVE_ARPA_INET_H define lib/sh/inet_aton.c - don't compile unless HAVE_NETWORK, HAVE_NETINET_IN_H, and HAVE_ARPA_INET_H are all defined in config.h or config-bot.h 2/16 ---- subst.c - if we have a construct like "${@:-}", we need to note that we're not using whatever is in $@ (we're using the rhs), so the special double-quoting $@ rules do not apply 2/21 ---- lib/readline/signals.c - declare SigHandler before using it on non-POSIX systems lib/sh/{zread,zwrite}.c - include unconditionally configure.in - m68k-motorola-sysv should be m68k-sysv in the section that sets opt_bash_malloc to no for certain systems builtins/complete.def - fixed a typo (stoppped) when printing out completion actions 2/22 ---- lib/sh/netopen.c - include if it's present aclocal.m4 - new macro, BASH_FUNC_INET_ATON, checks for inet_aton(3) including and , which some systems require to resolve the function configure.in - if autoconf can't fund inet_aton on its own, try BASH_FUNC_INET_ATON pcomplete.c - fixed a memory leak in gen_wordlist_completions - changed gen_wordlist_completions to do prefix-matching against the word being completed doc/bash.1, lib/readline/doc/rluser.texinfo - documented the change in behavior of the -W option to complete and compgen builtins/umask.def - if parse_symbolic_mode() returns -1, symbolic_umask needs to return -1 as well, otherwise the umask will be changed inappropriately input.c - always compile in getc_with_restart and ungetc_with_restart parse.y - yy_stream_get and yy_stream_unget now call getc_with_restart and ungetc_with_restart, respectively, to avoid problems with some systems not restarting the read(2) when signals that bash handles are received during the read (since bash installs its signal handlers without the SA_RESTART flag) lib/readline/complete.c - don't default rl_completion_case_fold to 1 if __DJGPP__ is defined 2/25 ---- subst.c - renamed `varlist' to `subst_assign_varlist' and made it global jobs.c - when running a SIGCHLD trap, need to unwind-protect subst_assign_varlist and set it to NULL before running the trap command (fix from ericw@bestnet.org and doogie@debian.org) 2/28 ---- lib/readline/doc/rltech.texinfo - document rl_funmap_names() 2/29 ---- subst.c - change split_at_delims to set the current word more appropriately when the cursor is between two words. Should probably change this again to set the current word like this only when the cursor is at whitespace or another delim just before the word start 3/1 --- lib/sh/shtty.c - more checks for flag bits being defined before using them 3/7 --- variables.h - fix typo in COPY_EXPORTSTR definition 3/14 ---- subst.c - changed split_at_delims so that if the cursor is at whitespace between words, and we're interested in the current word (cwp != NULL), make a new empty word and set the cwp to that word locale.c - support for setting LC_NUMERIC locale category based on value of LC_NUMERIC shell variable variables.c - LC_NUMERIC is now treated specially doc/{bash.1,bashref.texi} - LC_NUMERIC updates 3/15 ---- pcomplete.c - fix to avoid freeing memory twice 3/17 ---- [bash-2.04 released] 3/20 ---- doc/bash.1 - minor typo fix to description of `xpg_echo' option in `echo' description 3/23 ---- parse.y - minor fix to parse_string_to_word_list to allow newlines in compound array assignments 3/27 ---- lib/readline/rltty.c - fixed a missing-semicolon syntax error in the old 4.3 BSD tty code support/mksignames.c - if SIGRTMAX is >= 2*NSIG, just #undef SIGRTMIN and SIGRTMAX. This is an issue on AIX 4.3 (only, so far) -- checked by configure, which #defines UNUSABLE_RT_SIGNALS if this is the case aclocal.m4 - new macro, BASH_CHECK_RTSIGS, checks whether or not real-time signals are defined with large values and defines UNUSABLE_RT_SIGNALS if they are config.h.in - place marker for UNDEF_RT_SIGNALS (initially undefined) configure.in - call BASH_CHECK_RTSIGS in the `bash miscellaneous' section 3/29 ---- subst.c - fixed a problem in match_pattern_char, where `string' was checked for a paren following a [?+!@], rather than `pat' - the code that checks whether or not to exit after a failed ${word?msg} substitution needs to check interactive_shell rather than interactive to avoid exiting if such a construct appears in a sourced file 3/31 ---- bashline.c - add `{' to the list of characters that need to be quoted by the completion code when appearing in a filename 4/1 --- lib/glob/fnmatch.c - fixed an error in brackmatch() while skipping the rest of a bracket expression after a character matched. When `c' was a backslash and *p was a backslash, as in a pattern like [/\\], the old code didn't take both backslashes into account and ended up skipping the `]' after erroneously concluding that it was quoted. Report and fix from akim@epita.fr 4/3 --- lib/readline/rltty.c - slight change to the BSD tty interface code, so that if the first ioctl fails, get_tty_settings returns -1 immediately - better checking of ioctl return values in BSD tty version of get_tty_settings 4/5 --- doc/{bash.1,bashref.texi} - documented use of LINES and COLUMNS variables 4/12 ---- lib/readline/rltty.c - change the SETATTR define for the termio tty driver to use TCSETAW (the analog of the termios TCSADRAIN) lib/glob/fnmatch.c - fix for posix-style bracket expressions ([:xxx:], [=x=]) broken by fix of 4/1 for quotes in bracket expressions 4/26 ---- subst.c - fix to list_string and get_word_from_string to make a non-whitespace IFS character preceded by IFS whitespace part of the current field delimiter, not a separate delimiter that would result in a separate null field when splitting. cf POSIX.2, 3.6.5, (3)(b). Bug reported by amc@cs.berkeley.edu - changed the behavior of the (currently undocumented) ${!prefix@} expansion to be analogous to the expansion of $@ in other contexts when double-quoted. ksh93 seems to do this. Bug reported by Ken Pizzini - changed read_comsub to ignore NUL bytes in the command substitution output, printing a warning message for now parse.y - changed shell_getc to ignore NUL bytes in the input, printing a warning message for now - changed read_a_line to print a warning when a NUL byte is encountered, like shell_getc does 5/18 ---- subst.c - make sure split_at_delims uses d2 only if it's non-null - make split_at_delims skip leading newlines in the string to split, if newline is a delimiter jobs.c - prevent hanging processes by marking a child process as not running (even if the shell thinks it is) when waitpid() returns -1/ECHILD -- this indicates that waitpid never returned a reasonable status for that child though, which may be a symptom of another problem builtins/cd.def - make `pwd' print an error message if the write fails when displaying the current directory lib/readline/histexpand.c - return NULL from history_find_word if history_tokenize_internal returns (char **)NULL rather than attempting to dereference a possibly-NULL pointer - change history_tokenize_internal to set *indp to -1 before any processing if indp is non-null 5/19 ---- builtins/trap.def - when in POSIX.2 mode and printing trap dispositions, print the signal name without the leading `SIG', as POSIX.2 requires 5/23 ---- lib/readline/readline.c - readline_initialize_everything now assigns $TERM to rl_terminal_name if the application has left it unset, and calls _rl_init_terminal_io with the resultant value lib/readline/doc/rltech.texinfo - updated the description of rl_terminal_name to note initialization parse.y - change parse_string_to_word_list to save and restore the value of current_command_line_count before calling back into the parser -- it will screw up history if the string extends over one line. Bug reported by Jan.Djarv@mbox200.swipnet.se 6/7 --- unwind_prot.h - change unwind_protect_string to pass the address of the variable to unwind_protect_var on machines where ints and char *s are not the same size unwind_prot.c - make sure we save the value of a variable in unwind_protect_var on machines where sizeof(char *) != sizeof(int), not the contents the value points to. Fix from Andreas Schwab 6/8 --- configure.in - auto-configure MacOS X without bash malloc (like Rhapsody) 6/12 ---- configure.in - replace `cygwin32' with `cygwin' builtins/evalfile.c - in _evalfile, change all instances of \r to \n in the file to be sourced and evaluated if __CYGWIN__ is defined input.c - change \r to \n in the buffer argument to make_buffered_stream and after calling zread() from b_fill_buffer if __CYGWIN__ is defined 6/29 ---- lib/sh/Makefile.in - add rest of dependency rules for makepath.o 7/3 --- jobs.c - changed `int' to `WAIT' in a couple of places for non-POSIX environments 7/5 --- locale.c - try to avoid an unnecessary memory allocation in localetrans() in the case that a translation for the string exists lib/readline/doc/rluserman.texinfo - change the `direntry' information to make it use rluserman instead of readline 7/6 --- execute_cmd.c - changes to execute_in_subshell so it honors a `!' prefixing a command inside a user subshell (...) support/config.{guess,sub} - add cases for Apple Darwin (Mac OS X) configure.in - Apple Darwin (MacOS X) uses its own malloc lib/readline/readline.h - removed bogus extern declaration of savestring 7/7 --- builtins/common.c - in get_working_directory, don't count on getcwd returning anything useful in the buffer passed as the first argument on failure; just use bash_getcwd_errstr in the error message examples/loadables/cut.c - loadable version of cut(1), from the FreeBSD source tree 7/18 ---- lib/readline/vi_mode.c - changed two instances of (*rl_getc_function) (rl_instream) to calls to rl_read_key(), which works better when using the readline callback interface builtins/evalfile.c - added FEVAL_CHECKBINARY flag for _evalfile; controls whether a check for a binary file is performed - FEVAL_CHECKBINARY is not set by source_file or maybe_execute_file, which means that the startup file execution and the `.' builtin will not check for binary files - FEVAL_CHECKBINARY is not set by fc_execute_file, so that files composed of history commands run by the `fc' builtin will not check for binary files 7/21 ---- shell.c - added `--init-file' as a synonym for `--rcfile' 7/26 ---- support/shobj-conf - added commented-out stanzas for hpux 10 and hpux 11 when the HP unbundled ANSI C compiler is being used 7/27 ---- shell.c - don't call end_job_control() from exit_shell if subshell_environment is non-zero, even if the shell is interactive 8/1 --- bashhist.c - change maybe_add_history to remember if we saved the first line of a command and don't save the second and subsequent lines of a multi-line command if we didn't save the first line configure.in, config.h.in - add autoconf check for getservbyname() lib/sh/netopen.c - add support for named services in /dev/(tcp|udp)/host/service translation - make sure _netopen sets errno to something other than 0 if something goes wrong, so the redirection functions behave 8/3 --- parse.y - changes to shell_getc so that history saving of blank lines in multi-line commands does a better job of syntactic correctness bashline.c - bind ^O to operate-and-get-next in emacs_standard_keymap explicitly, rather than letting rl_add_defun do it in whatever keymap is current 8/4 --- builtins/ulimit.def - removed some of the special handling of RLIM_INFINITY -- the old code would let people use RLIM_INFINITY as a shorthand for setting the soft limit to the hard limit. Now, the code just passes RLIM_INFINITY through if the hard limit is being set, so any kernel errors will get through 8/10 ---- parse.y - change the grammar rule for group_command so that it's composed of a compound_list instead of a list, which requires a terminator This means that you can now do (legal) things like { { echo a b c ; } } since the second close brace will be recognized as such because a reserved word is legal in that context 8/23 ---- subst.c - fix parameter_brace_substring to free all memory allocated by get_var_and_type in the VT_ARRAYMEMBER case (returned parameter `val') 8/30 ---- variables.c - now that we have dynamic array variables, remove the check for array_p in bind_variable and let array variables with assignment functions call the assignment function subst.c - change cond_expand_word to perform tilde expansion (like it should have done all along) lib/readline/complete.c - don't allow backslash to quote anything inside a single-quoted string in find_completion_word doc/{bash.1,bashref.texi} - note that `set -a' will cause functions to be exported lib/readline/parens.c - changed the blink timeout so it's settable by the application. A new function, int rl_set_paren_blink_timeout (int u), (still undocumented) will set the timeout to U usec variables.c - at startup of an interactive login shell, if the current directory is $HOME, and $HOME and $PWD are not the same, set the current directory (and $PWD) to $HOME - break code that initializes $PWD and $OLDPWD into set_pwd function variables.h - new extern declaration for set_pwd() 9/6 --- lib/readline/{readline,callback}.c - allocate memory for rl_prompt instead of simply using what's passed as the `prompt' argument to readline() or rl_callback_handler_install(). This will allow constant strings to be passed to readline(), since the prompt processing code wants to write to rl_prompt lib/sh/pathcanon.c - new file, does pathname canonicalization externs.h - extern declarations for stuff in lib/sh/pathcanon.c general.c - canonicalize_pathname now simply calls sh_canonpath() 9/7 --- pcomplete.h - new member in a `struct compspec': options - define some flag values for options field pcomplib.c - make sure options field is allocated and copied by compspec utility functions builtins/complete.def - add struct for completion options. These control the `meta-behavior' of the compspec. Initially, there are three: default - perform bash default completion if programmable completion produces no matches dirnames - perform directory name completion if programmable completion produces no matches filenames - tell readline that the compspec produces filenames, so it can do things like append slashes to directory names and suppress trailing spaces - add `-o option' to complete and compgen, setting new options field in a compspec - add code to display any -o options when a compspect is printed with the `-p' option to complete pcomplete.c - programmable_completions now passes back to the caller in the last argument any options associated with the active compspec (from the options field) - change gen_compspec_completions to re-call gen_action_completions with a CA_DIRECTORY action if the rest of the compspec actions generate no matches and the COPT_DIRNAMES option is present bashline.c - if a programmable completion was specified to return filenames with the `-o filenames' option, set rl_filename_completion_desired to 1 so readline does its special filename-specific things - if a compspec was defined to fall back to the readline default with the `-o default' option, suppress setting the rl_attempted_completion_over variable in attempt_shell_completion so readline will go on and do filename completion include/ansi_stdlib.h - add extern declarations for atof and strtod builtins/printf.def - change getdouble() to use strtod (since we provide a version in libsh if the C library doesn't have one), and change the calling convention to match the other getXXX functions (take value pointer as argument, return success or failure). This makes printf handle invalid floating point numbers better doc/bash.1, lib/readline/doc/rluser.texinfo - documented new `-o' option to complete and compgen; described the arguments and their effects lib/readline/{macro,util}.c - renamed _rl_executing_macro to rl_executing_macro; made it public lib/readline/readline.h - new extern declaration for rl_executing_macro lib/readline/rltech.texinfo - documented rl_executing_macro 8/8 --- lib/readline/readline.c - new state variable, rl_readline_state lib/readline/readline.h - extern declaration for rl_readline_state - define some flag bits for rl_readline_state and macros to test and set them lib/readline/{readline,complete,isearch,macro,rltty,search,signals,undo,vi_mode}.c - added calls to the macros that set and unset various readline states lib/readline/readline.c - new private function, _rl_free_saved_history_line, to free up the history entry saved in saved_line_for_history lib/readline/search.c - free any saved history entry in rl_history_search_reinit(), because rl_get_previous_history makes a call to maybe_save_line without freeing up the saved line when it returns (so rl_get_next_history can use it) - fix up noninc_search_from_pos to deal with invalid history indices better 9/12 ---- support/shobj-conf - HPUX 11.0 needs the `-fpic' flag passed to the linker as well as the compiler execute_cmd.c - on MS-DOS systems, let the #! checking stuff in execute_shell_script treat \r as EOL (identical to \n) input.c - on DJGPP systems, allow buffered_getchar to ignore \r. Change suggested by snowball3@bigfoot.com 9/13 ---- lib/sh/tmpfile.c - new file, with functions for creating and (hopefully safely) opening temporary files for the shell externs.h - extern declarations for functions in tmpfile.c variables.c - new function, get_random_number, returns random values from the shell's (lame) RNG to the rest of the shell variables.h - new extern declaration for get_random_number() subst.c - changed make_named_pipe to call sh_mktmpname instead of mktemp redir.c - changed here_document_to_fd to call sh_mktmpfd instead of using inline code builtins/fc.def - changed fc_builtin to call sh_mktmpfp instead of using inline code builtins/common.h - new extern declaration for fc_execute_file() bashline.c - if RL_ISSTATE(RL_STATE_INITIALIZED) is 0 in initialize_readline, call rl_initialize to bind the defaults before setting up our custom shell functions and key bindings lib/readline/doc/{rluser,hsuser}.texinfo - some markup changes proposed by dima@chg.ru lib/readline/rlstdc.h, lib/tilde/tilde.h - to get ready for some `const' changes to the source, define const as either `__const' (gcc -traditional) or nothing if __STDC__ and __cplusplus are not defined lib/readline/readline.c - upped the default readline version to `4.2-alpha' lib/readline/readline.[ch] - readline now takes a `const char *' as an argument lib/readline/history.h - read_history(), read_history_range(), write_history(), append_history(), history_truncate_file() now take `const char *' filename arguments lib/readline/histfile.c - history_filename(), read_history(), read_history_range(), write_history(), append_history(), history_truncate_file(), history_do_write() now take `const char *' filename arguments lib/readline/readline.h - rl_read_init_file() now takes a `const char *' filename argument lib/readline/bind.c - current_readline_init_file is now a `const char *' - _rl_read_init_file(), rl_read_init_file() now take `const char *' filename arguments lib/tilde/tilde.c - tilde_expand(), tilde_expand_word() now take a `const char *' as their first argument lib/readline/chardefs.h - fixed CTRL_CHAR macro to be right on systems where chars are unsigned by default 9/14 ---- lib/readline/doc/{rl,hs}tech.texinfo - documented new `const char *' function arguments where appropriate lib/readline/vi_mode.c - clamp the numeric argument in vi mode at 999999, just like in emacs mode lib/readline/doc/rltech.texinfo - documented rl_readline_state and its possible bit values builtins/source.def - in maybe_pop_dollar_vars, don't overwrite a shell function's argument list even if the sourced script changes the positional parameters lib/readline/{util.c,rlprivate.h} - made _rl_strindex() and _rl_savestring() take `const char *' arguments 9/15 ---- subst.c - renamed `doing_completion' to `no_longjmp_on_fatal_error', a more accurate description of its current behavior pcomplete.[ch], externs.h, lib/sh/stringlist.c - moved the stringlist code from pcomplete.c to lib/sh/stringlist.c - moved the type declaration and extern function declarations from pcomplete.h to externs.h stringlib.c, externs.h, lib/sh/stringvec.c - moved the char array code from stringlib.c to lib/sh/stringvec.c 9/18 ---- subst.c - new static variable, expand_no_split_dollar_star, to ensure that $* isn't `split and rejoined' when expanded via a call to expand_string_unsplit or expand_word_no_split 9/19 ---- subst.[ch], execute_cmd.c - renamed expand_word_no_split to expand_word_unsplit copy_cmd.c - in copy_word, just assign w->flags to new_word->flags rather than bcopying the entire structure configure.in, config.h.in - add autoconf check for pathconf(3) lib/sh/tmpfile.c - test for systems with short filenames using pathconf and _PC_NAME_MAX, so generated temp file names don't exceed that length (only do this if the file name length is less than 32, since the current code doesn't generate filenames longer than about 17 chars) 9/20 ---- command.h - added `W_NOSPLIT2' word flag to prepare for supporting weird $@ expansion on the rhs of assignment statements (inspecting the ksh93 behavior, it seems like nothing except $@ is split, and $@ is split on $IFS and rejoined as a single string) 9/21 ---- subst.c - since verify_substring_values looks for arithmetic expressions bounded by `:', do some ad-hoc parsing of the substring passed as the argument to avoid cutting the expression off at the wrong `:' (since the inclusion of conditional expressions, expressions may contain a `:'). Do some paren balancing, too. 9/22 ---- command.h - new #define, CLOBBERING_REDIRECT, evaluates to true for any redirect that will clobber a file and should be subject to `noclobber' redir.c - changed redir_open to use CLOBBERING_REDIRECT instead of OUTPUT_REDIRECT. This means that <> no longer tests the value of noclobber, as POSIX.2 specifies parse.y - made a change to cond_term so that expressions like [[ (x) ]] are parsed correctly 9/25 ---- parse.y - small change to grammar for arith_for_command and special_case_tokens to allow `do...done' or {...} after ((...)) without an intervening list_terminator (for ksh93 compatibility) builtins/printf.def - `printf' now treats \E and \e the same when performing backslash escape expansion for the %b format character for compatibility with $'...' quoting (for ksh93 compatibility) 9/26 ---- builtins/source.def - new variable, source_searches_cwd, initially 1. If non-zero, `.' searches $PWD for the filename argument if it's not found in $PATH general.c - changed posix_initialize to turn off source_searches_cwd if posix mode is being enabled; turn it on if posix mode is being disabled - changed things so interactive_comments is not turned off if posix mode is disabled, since that's rarely what is desired variables.c - changed uidset() to set UID and EUID only if they are not already set when the shell starts up - changed things to HOSTNAME is set only if it's not set when the shell starts up execute_cmd.c - changed execute_builtin_or_function so that if a command like `command exec 4 as appropriate lib/readline/{display.c,readline.h} - rl_redisplay_func is now of type rl_voidfunc_t * lib/readline/{callbacks.c,readline.h} - the `linefunc' argument to rl_callback_handler_install and the rl_linefunc variable are now of type rl_vcpfunc_t * lib/readline/{complete.c,readline.h} - rl_completion_display_matches_hook is now of type rl_compdisplay_func_t * - rl_directory_completion_hook is now of type rl_icppfunc_t * lib/readline/{history.h,histexpand.c} - history_inhibit_expansion_function is now of type rl_linebuf_func_t * lib/readline/histexpand.c - new private type, _hist_search_func_t, used to indirect through the various history search functions lib/tilde/tilde.h - new typedef, tilde_hook_func_t, which takes a char * and returns a char * lib/tilde/tilde.[ch] - tilde_expansion_preexpansion_hook and tilde_expansion_failure_hook are now of type tilde_hook_func_t * [THERE ARE NO LONGER ANY REFERENCES TO Function *, CPFunction *, or CPPFunction * IN THE READLINE SOURCE, WHICH INCLUDES THE TILDE LIBRARY] {bashline,bracecomp}.c, bashline.h - changes for changed type of rl_completion_entry_func and other changed types (rl_compentry_func_t, rl_completion_func_t, const changes for prototypes, etc.) pathexp.[ch] - shell_glob_filename now takes a `const char *' argument - quote_string_for_globbing now takes a `const char *' argument 10/31 ----- lib/sh/zwrite.c - fix zwrite() to update the buffer pointer in the case of a partial write, in addition to decreasing the count of bytes to be written support/config.{guess,sub} - added entries for MIPS-based Compaq machines running NonStopUX 11/1 ---- lib/readline/undo.c - renamed free_undo_list to be rl_free_undo_list, made a dummy replacement function free_undo_list that just calls rl_free_undo_list lib/readline/readline.h - extern declaration for rl_free_undo_list lib/readline/{readline,signals}.c - changed calls to free_undo_list to rl_free_undo_list lib/readline/doc/rltech.texinfo - changed all function types and arguments for new typedefs 11/2 ---- lib/readline/{rlprivate.h,terminal.c,display.c} - term_clreol, term_clrpag, term_cr, term_backspace, term_goto, term_pc, term_im, term_ei, term_ic, term_ip, term_IC, term_dc, term_DC, term_forward_char, term_up, term_mm, term_mo, term_ku, term_kd, term_kr, term_kl, term_ks, term_ke, term_kh, term_kH, terminal_can_insert variables all now have a _rl_ prefix lib/readline/{rlprivate.h,terminal.c,display.c, readline.c} - screenheight, screenwidth, screenchars now have an _rl_ prefix lib/readline/{terminal,complete,isearch,kill,macro,readline,search,undo,util,vi_mode}.c - changed calls to ding to calls to rl_ding lib/readine/{isearch,readline,search}.c - saved_line_for_history now has an _rl_ prefix lib/readline/readline.[ch] - renamed maybe_{replace,save,unsave} line to have an rl_ prefix lib/readline/{readline,search,isearch}.c - changed calls to maybe_{replace,save,unsave} line to call the rl_-prefixed equivalents lib/readline/{rlprivate.h,readline.c,util.c} - renamed alphabetic to rl_alphabetic;

Completely internal, not user-settable execute_cmd.c - treat noassign variables like readonly variables, except an attempt to assign to them does not cause a non-interactive shell in POSIX mode to abort {subst,variables}.c,builtins/declare.def - attempts to assign to `noassign' variables return an error status, but no error messages -- almost identical to readonly variables variables.c - GROUPS and FUNCNAME are `noassign' variables, meaning assignment to them is disallowed, but that they may be unset (in which case they lose their special properties) doc/{bash.1,bashref.texi} - documented that assignments to GROUPS and FUNCNAME are disallowed and return an error status 11/8 ---- lib/readline/{funmap.c,bind.c,rlprivate.h} - _rl_possible_{control,meta}_prefixes are now arrays of `const char *' and are defined in bind.c, since that's where they're used lib/readline/rltty.c - changed prepare_terminal_settings to take an `oldtio' argument instead of `otio', which shadows the global declaration lib/readline/bind.c - the `name' member of a parser_directive element is now a `const char *' - the `name' member of a boolean_varlist element is now a `const char *' - the `name' member of a string_varlist element is now a `const char *' - the `name' member of an assoc_list element is now a `const char *' - the `name' member of an keymap_names element is now a `const char *' lib/readline/display.c - changed scope-local char * variable `temp' to `vtemp' because there's already a function local variable named `temp' of a different type (int) in rl_redisplay lib/readline/util.c - pathname_alphabetic_chars is now `const char *' lib/readline/terminal.c - the `tc_var' member of a _tc_string element is now a `const char *' lib/readline/histexpand.c - changed history_expand_internal to remove the duplicate local declaration of `t' in the `s'/`&' case lib/readline/histfile.c - in history_filename, `home' is now a `const char *' lib/tilde/tilde.c - default_prefixes and default_suffixes are now arrays of `const char *' lib/readline/vi_mode.c - vi_motion and vi_texmod are now `const char *' lib/readline/complete.c - simplified the conditional declaration of getpwent() variables.[ch] - get_string_value now takes a `const char *' argument 11/10 ----- display.c - changes to expand_prompt and rl_redisplay to keep track of the number of invisible characters on the first line of the prompt, in case it takes up more than one physical line, and not all invisible chars are on the first line - the code that determines the index into the line at which to wrap the first line if the visible prompt length exceeds the screen width was changed to use the number of invisible chars in the first physical prompt line rather than the total number of invisible characters - changed redraw_prompt to save and restore prompt_invis_chars_first_line subst.c - changed expand_string_internal to savestring() the string argument to avoid possible doubly-freed memory on substitution errors - fixed expand_word_list_internal so that commands with assignment statements preceding words that expand to nothing return a failure status if one of the assignments fails; for example readonly TVAR TVAR=7 $ECHO $ABCDE - made sure that all cases of jump_to_top_level set last_command_exit_value to something non-zero before jumping, since they are by definition errors builtins/evalstring.c - changed parse_and_execute to set last_result to EXECUTION_FAILURE along with last_command_exit_value in the `DISPOSE' case of a jump_to_top_level, since we can return this value in most (interactive) circumstances 11/14 ----- general.c - fix legal_number so that it skips any trailing whitespace in its string argument after strtol returns, since strtol does not lib/readline/{complete.c,readline.h} - new function pointer, rl_directory_rewrite_hook, identical in effect to rl_directory_completion_hook except that it does not modify what is displayed when the possible completions are listed or inserted bashline.c - changed tcsh_magic_space to try and insert a space closer to where the point was originally, rather than always inserting it at the end of the line 11/16 ----- jobs.c - fixed a bug that happened on cygwin systems that caused the jobs table to fill up if a file sourced from an interactive shell ran lots of jobs -- notify_and_cleanup() never called notify_of_job_status subst.c - fixed pat_match to avoid infinite recursion on zero-length matches from match_pattern 11/17/2000 ---------- [bash-2.05-alpha1 released] 11/18 ----- support/shobj-conf - added GNU Hurd support, identical to linux variables.c - cygwin systems don't use the exportstr stuff at all, so call INVALIDATE_EXPORTSTR before testing var->exportstr, since just blindly using the value_cell will break exported functions that already have an exportstr set - when recomputing the exported value because valid_exportstr fails, make sure to call named_function_string if the variable is a shell function 11/20 ----- variables.c - removed call to valid_exportstr; the exportstr code has been adequately debugged lib/glob/fnmatch.c - reverted to the POSIX.2 behavior of using the current locale and strcoll() to evaluate range expressions in bracket expressions doc/{bash.1,bashref.texi} - added note to Pattern Matching section emphasizing that the current locale plays a part in evaluating range expressions within [...] aclocal.m4 - added an #include to the test for posix sigaction restarting interrupted system calls support/config.guess - changes from Tim Mooney to support `letter version' releases of Tru 64 Unix on the Alpha (e.g., 5.1a) 11/21 ----- lib/sh/pathphys.c - make sure MAXSYMLINKS is defined aclocal.m4 - changed BASH_CHECK_PWFUNCS to just use AC_EGREP_CPP on a file that includes pwd.h and other header files, checking for getpwuid. It #defines HAVE_GETPW_DECLS if the egrep succeeds lib/readline/complete.c - provide extern declaration of getpwent if _POSIX_SOURCE is defined, since most systems don't declare it in unless _POSIX_SOURCE is undefined 11/22 ----- input.c - fixed a small typo in the cygwin-specific code doc/{bashref.texi,bash.1} - added some more explanatory text about the effect of the current locale's collating order on range expressions within bracket expressions doc/bashref.texi, lib/readline/doc/{rltech,rluser,hstech}.texinfo - changed to use @env instead of @code for the names of environment and shell variables in text (not in tables yet) 11/27 ----- configure.in - configure without the bash malloc on Interix lib/readline/doc/rltech.texinfo - changed completion_matches() to rl_completion_matches() - changed filename_completion_function() to rl_filename_completion_function() - changed username_completion_function() to rl_username_completion_function() lib/readline/rlprivate.h - changed declaration of _rl_alphabetic to rl_alphabetic, since that's what's used in the C files support/bashbug.sh - Debian has /usr/bin/editor as a link to the system default editor; make that one of the alternatives if $EDITOR is not set - if the OS provides mktemp(1) or tempfile(1), use those to create the temp file for the bug report lib/readline/{readline.[ch], callback.c} - new function, rl_set_prompt, called with prompt string as argument, sets and, if necessary, expands rl_prompt lib/readline/{complete.c,compat.c,readline.h} - rl_completion_matches now takes a `const char *' as its first argument - compute_lcd_of_matches now takes a `const char *' as its third argument lib/readline/rltypedefs.h - a rl_completion_func_t now takes a `const char *' as its first argument lib/readline/Makefile.in - added dependencies on rltypedefs.h bashline.c - attempt_shell_completion now takes a `const char *' as its first argument - removed bogus cast when assigning to rl_attempted_completion_function and rl_completion_entry_function - bash_directory_completion_matches takes a `const char *' argument pcomplete.c - gen_matches_from_itemlist, pcomp_filename_completion_function, gen_action_completions, gen_globpat_matches, gen_wordlist_matches, gen_compspec_completions now take `const char *' arguments as appropriate - programmable_completions now takes `const char *' first and second arguments pcomplib.c - find_compspec now takes a `const char *' argument 11/29 ----- shell.c - in open_shell_script, if we have /dev/fd, don't perform the check for a binary file if isatty(fd) (where fd is opened on the script name) returns non-zero - in open_shell_script, don't call init_noninteractive again, since it can undo changes made by the startup files ($BASH_ENV) input.c - in fd_to_buffered_stream, make sure buffer size (and hence size arg passed to read(2)) is greater than zero. This makes bash /dev/stdin work right. - return -1 from sync_buffered_stream immediately if buffers is NULL (can happen when running `bash -i /dev/stdin' and executing a command that requires a fork) 11/30 ----- jobs.c - renamed cont_signal_handler to sigcont_sighandler for consistency - renamed stop_signal_handler to sigstop_sighandler for consistency - if there is no jobs list or no outstanding jobs, return immediately from notify_of_job_status, before fussing with the signal state - change map_over_jobs to not fuss with the signal state unless there are jobs lib/malloc/malloc.c - encapsulated the code to block and unblock signals during morecore() execution into two functions: block_signals and unblock_signals - only block signals in morecore() if interrupt_immediately is non-zero or SIGINT or SIGCHLD is trapped 12/1 ---- lib/readline/readline.c - fix to rl_forward to make sure that lend doesn't get set < 0, since that will result in rl_point being < 0 12/5 ---- parse.y - fix to parse_matched_pair to allow backslash to escape a ' inside a $'...' construct inside another grouping construct like ${...} - translate $'...' and $"..." in parse_matched_pair, because nothing else will do it if such a construct appears inside a grouping construct 12/6 ---- configure.in - make sure all bracket tests for pattern matching in case statements are appropriately quoted, so autoconf doesn't swallow the brackets - add -rdynamic to LOCAL_LDFLAGS for freebsd-4.x examples/loadables/realpath.c - new loadable builtin, canonicalizes pathnames and expands symlinks builtins/ulimit.def - added undocumented -w option for setting RLIMIT_SWAP, if it's defined 12/7 ---- bashline.c - reordered code in initialize_readline so all of the rl_add_defun calls are made before the call to rl_initialize, and all of the rl_{bind,unbind}_key_in_map calls are made after initializing readline. This allows the bash-specific function names to be used in ~/.inputrc 12/12 ----- lib/readline/callback.c - in rl_callback_read_char, loop after returning from readline_internal_char and test rl_pending_input in case some function (like the incremental search functions and digit argument functions) pushed input back with rl_execute_next lib/readline/readline.h - new rl_state flag: RL_STATE_INPUTPENDING, indicating that rl_execute_next has pushed input back for rl_get_key to read lib/readline/input.c - new function to clear rl_pending_input: rl_clear_pending_input() lib/readline/{input,readline,signals}.c - when rl_pending_input is set, set state RL_STATE_INPUTPENDING; unset that state when rl_read_key returns the pending input - call rl_clear_pending_input at appropriate points 12/15 ----- lib/readline/histfile.c - don't leak file descriptors while attempting to truncate a non-regular file input.c - make sure check_bash_input sets the close-on-exec flag for the file descriptor used to save the bash input fd parse.y - if default_buffered_input gets changed while it's on the saved stream stack, make sure it gets set to close-on-exec when it's restored by pop_stream() 12/18 ----- builtins/ulimit.def - change set_limit to account for Cygwin's setdtablesize() being declared as a void function support/config.{guess,sub} - change cygwin32 to cygwin 12/20 ----- nojobs.c - make wait_sigint_handler handle the case of interrupt_immediately being non-zero when it's called, and jump out appropriately jobs.c - new function to run sigchld traps: run_sigchld_trap(); called from waitchld - broke the code that computes the printable job status messages for pretty_print_job out into a separate function - rearranged some code eliminating a useless `else' branch in wait_for - shell_tty_info is now a TTYSTRUCT, using defines from shtty.h - broke the code that sets a job's status after waitpid says its state has changed and cleans up after a received SIGINT out into a separate function: set_job_status_and_cleanup - last_stopped_job() -> job_last_stopped() to avoid collision with a variable name - last_running_job() -> job_last_running() for consistency 12/21 ----- variables.c - new function, print_func_list (SHELL_VAR **list); prints shell functions from list in a form that may be re-used as input to redefine the functions variables.h - new extern declaration for print_func_list builtins/set.def - set without options now calls print_func_list to have functions printed in a way that can be reused as input (this affects `declare' and `declare -p' also) 12/27 ----- general.h - add an ISOCTAL define builtins/common.h - use ISOCTAL in read_octal function parse.y - in decode_prompt_string, don't just skip STRING forward by 3 if an octal sequence is translated; handle sequences of fewer than three characters by checking each character 12/28 ----- doc/{bash.1,bashref.texi} - make sure `vi-move' is a documented keymap argument to bind's `-m' option 12/29 ----- variables.c - change print_assignment so that functions are printed in a way that may be reused as input (without the `=') 1/2/2001 -------- test.c - fix test_command to print an error message if `[' is supplied a single argument that is not `]' support/shobj-conf - change test of $SHOBJ_CC from `gcc*' to `*gcc*' to handle full pathnames 1/11 ---- execute_cmd.c - in initialize_subshell, zero out builtin_env, since those aren't supposed to be exported variables.c - new function: shell_var_from_env_string, creates a SHELL_VAR from a `name=value' style environment string and returns it - new function: bind_name_in_env_array(name, value, array), makes NAME have VALUE in ARRAY, a temporary environment - new function: bind_tempenv_variable (name, value), makes NAME have VALUE in one of the temporary environments -- temporary_env, builtin_env, or function_env - changed bind_variable to call bind_tempenv_variable if one of the temporary environments is non-null before modifying the shell_variables table. This fixes a problem with sourced scripts modifying variables in a temporary environment, but not seeing the updated values 1/12 ---- variables.c - changed things so OSTYPE, HOSTTYPE, and MACHTYPE are set only if they don't have a value at shell startup 1/17 ---- builtins/fc.def - create temp file with MT_USETMPDIR variables.c - allow function local readonly variables to overwrite (or shadow) other (calling) function readonly variables, but not global readonly ones builtins/wait.def - replace unwind_protect of interrupt_immediately, since that's a variable that you cannot unwind-protect (the unwind-protect code uses it) 1/22 ---- Makefile.in - changed RELSTATUS to `beta1' lib/readline/terminal.c - added rl_set_screen_size function, wrapper around _rl_set_screen_size so bash doesn't call _rl_ functions lib/readline/{rlprivate,readline}.h - moved rl_explicit_arg to readline.h - moved rl_numeric_arg to readline.h - moved rl_editing_mode to readline.h - moved rl_last_func to readline.h - added rl_set_screen_size to readline.h lib/readline/doc/rltech.texinfo - documented rl_explicit_arg, rl_editing_mode, rl_numeric_arg, rl_last_func - documented rl_set_screen_size {jobs,nojobs}.c - _rl_set_screen_size -> rl_set_screen_size {bashline,pcomplete}.c, builtins/set.def - removed extern declarations of variables defined in readline.h 1/23 ---- support/rlvers.sh - use $TMPDIR if it's defined - use $RL_INCDIR (set by -I option, /usr/local/include by default) as the directory containing the installed readline header files - cd to the temp directory before attempting compilation configure.in - pass `-I ${includedir}' to rlvers.sh 1/29 ---- subst.c - fixed parameter_brace_expand to only throw away the state of quoted dollar-at if we're going to be using the rhs of the brace expansion, since whatever parameter_brace_expand_rhs sets should be what goes (corrects bad fix of 2/16/2000) - fixed param_expand to only free temp after calling parameter_brace_expand if it's a quoted null and we *did not* have a quoted $@, since in that case we want to keep it and do the $@ special handling (fixes real problem from 2/16/2000) 1/30 ---- variables.c - remove export attribute from SSH2_CLIENT, like SSH_CLIENT 2/1 --- unwind_prot.c - added new function, clear_unwind_protect_list, to zero out the unwind_protect list, optionally freeing the elements unwind_prot.h - new extern declaration for clear_unwind_protect_list execute_cmd.c - call clear_unwind_protect_list in initialize_subshell. This fixes the problem of core dumps when calling a shell script without a leading `#!' from a shell function or other context with an unwind-protect list - set variable_context and return_catch_flag to 0 in initialize_subshell, since a new subshell is no longer in a shell function 2/2 --- doc/readline.3 - updated the text; clarified several points - changed the usage synopsis to include and lib/readline/doc/hstech.texinfo - made sure all function prototypes are valid ANSI C (mostly changing () to (void)) lib/readline/doc/rluser.texinfo - a few clarifications lib/readline/doc/rltech.texinfo - a few clarifications - added two new subsections for character input and terminal management - changed all function prototypes to be valid ANSI C (mostly replacing () with (void)) - documented some variables in readline.h but previously not in the reference manual (rl_num_chars_to_read, rl_dispatching, rl_gnu_readline_p, rl_completion_type) - documented some functions in readline.h but previously not in the reference manual (rl_clear_pending_input, rl_prep_terminal, rl_deprep_terminal, rl_tty_set_default_bindings, rl_alphabetic, rl_crlf) lib/readline/readline.h - added extern declaration for rl_clear_pending_input() - added extern declaration for rl_alphabetic - changed rltty_set_default_bindings to rl_tty_set_default_bindings - changed crlf() -> rl_crlf() lib/readline/rltty.c - new function, rl_tty_set_default_bindings, just calls rltty_set_default_bindings (needed `rl_' prefix) lib/readline/readline.c - readline_default_bindings now calls rl_tty_set_default_bindings lib/readline/terminal.c - renamed crlf() to rl_crlf(); crlf() is still defined for backwards compatibility bashline.c, lib/readline/{complete,display}.c - changed all calls to crlf() to rl_crlf() test.c - fix filecomp() so that `test file1 -nt file2' doesn't fail if file1 exists but file2 does not 2/5 --- lib/readline/{terminal,compat}.c - move crlf() backwards-compatibility definition to compat.c execute_cmd.c - if we're running a command `( command ) &' from a non-interactive shell, don't unconditionally disable expand_aliases. Only do it when running such a command from an interactive shell, since then we're changing to a non-interactive shell 2/6 --- [bash-2.05-beta1 released] lib/readline/compat.c - add extern declaration for rl_crlf() lib/readline/undo.c - initialize start and end in rl_do_undo to avoid bogus gcc compiler warning with -Wall lib/readline/rlprivate.h - fix typo in extern declaration of _rl_current_display_line() - add extern declaration of _rl_free_saved_history_line() lib/readline/terminal.c - return immediately from _rl_set_screen_size if one of the args is 0 - new function, rl_get_screen_size (int *rows, int *cols) to return readline's idea of the screen dimensions lib/readline/doc/rltech.texinfo - documented rl_get_screen_size 2/7 --- pathexp.c - a couple of fixes for the POSIX_GLOB_LIBRARY version of the globbing code expr.c - fixed omission of ^= from the special assignment operators shell.c - change logic for setting `posixly_correct' at shell startup: if $POSIXLY_CORRECT or $POSIX_PEDANTIC is found in the environment, set it to 1, otherwise retain the previous value (which is initialized to 0) 2/10 ---- builtins/evalstring.c - since subshell_environment is now a flags word, test for the SUBSHELL_COMSUB bit being set when decided whether or not to evaluate $(flag: B_WASBASHINPUT redir.c - in add_undo_redirect, if FD is 0, make the undo redirect be of type r_duplicating_input instead of r_duplicating_output, since that fd requires special handling in the presence of buffered streams (fixes problem with scripts reading input through a pipe restoring bash input buffered stream correctly after a `read' with an input redirection 2/14 ---- lib/readline{complete,util}.c - moved rl_strpbrk to util.c with rest of string utility functions, renamed to _rl_strpbrk lib/readline/rlprivate.h - extern declaration for _rl_strpbrk lib/readline/input.c - make the timeout in rl_gather_tyi() be a variable (_keyboard_input_timeout) rather than a constant - new function, rl_set_keyboard_input_timeout (int u) to set _keyboard_input_timeout. The argument is in microseconds; returns the old value of _keyboard_input_timeout - _rl_input_available uses _keyboard_input_timeout also lib/readline/readline.h - extern declaration for rl_set_keyboard_input_timeout lib/readline/doc/rltech.texinfo - documented rl_variable_bind(), rl_macro_bind(), rl_macro_dumper(), rl_variable_dumper(), rl_push_macro_input(), rl_show_char() 2/20 ---- findcmd.c - new function, executable_or_directory(name), returns 1 if NAME is an executable file or a directory findcmd.h - extern declaration for executable_or_directory() bashline.c - call executable_or_directory() from command_word_completion_function, which requires a single stat(2), instead of executable_file() and is_directory(), each of which requires a stat(2) 2/21 ---- execute_cmd.c - changed execute_builtin to handle `return' with a preceding variable assignment list specially when in POSIX mode. POSIX says that the variable assignments should persist after the builtin returns, since `return' is a special builtin. Since `return' does a longjmp and doesn't go through the normal cleanup path, we need to do special things variables.c - new function, merge_function_env(), merges the function_env into the shell_variables table variables.h - extern declaration for merge_function_env() execute_cmd.c - changed execute_function to merge any variable assignments preceding the function call into shell_variables if the shell is running in POSIX mode subst.c - changed parameter_brace_expand_error to do tilde expansion on the rhs of the expansion, if it's not null - changed command_substitute so that the subshell begun to execute the command substitution inherits the setting of the `-e' option when in POSIX mode builtins/break.def - changed check_loop_level to not print a complaining message when the shell is running in POSIX mode, even if BREAK_COMPLAINS is defined. This affects `break' and `continue' - changed `break' and `continue' to return success even if the shell is not executing a loop, as POSIX specifies builtins/set.def - changed reset_shell_options() to not clear posixly_correct, so subshells spawned to execute shell scripts without a leading `#!' inherit posix mode from their parent shell variables.c - changed make_new_variable to create the shell_variables hash table if it hasn't been done yet. This is needed because bind_variable may be called before initialize_shell_variables (e.g., when `bash -o posix' calls bind_variable("POSIXLY_CORRECT", "y") from parse_shell_options -> set_minus_o_option -> set_posix_mode This makes `bash --posix' and `bash -o posix' equivalent, as they should always have been - changed maybe_make_export_env to merge the contents of `builtin_env' into export_env after function_env and before temporary_env. This fixes the problems with variable assignments preceding `eval' or `source' not making it into the environment passed to executed disk commands (var=20 eval printenv var) doc/bashref.texi - noted that variable assignments preceding shell function calls persist in the shell environment after the function returns when the shell is running in POSIX mode - noted that when the shell is running in POSIX mode, subshells spawned to execute command substitutions inherit the value of the `-e' option from the parent shell 2/26 ---- doc/bashref.texi - augmented description of bash non-posix behavior in posix mode with information from running the vsc-lite test suite 2/28 ---- general.c - since POSIX.2 says that aliases should be expanded even in non-interactive shells, enable alias expansion in posix_initialize() when posix mode is enabled, and set it to the value of interactive_shell if posix mode is disabled shell.c - before running the startup scripts, set expand_aliases to posixly_correct, since we don't want alias expansion in startup files unless we've been given the --posix invocation option doc/bashref.texi - added item in BASH Posix Mode section noting that alias expansion is always enabled when in posix mode Makefile.in - changed release level to `beta2' 3/1 --- jobs.c - expanded retcode_name_buffer to 64 - changed printable_job_status to conform to posix.2 for text of stopped job status: `Stopped(SIGTSTP)' or `Stopped(SIGSTOP)' doc/bashref.texi - Noted above change in posix mode section 3/5 --- lib/readline/bind.c - changed rl_get_keymap_by_name to work case-insensitively 3/6 --- doc/readline.{0,3,ps} - removed from distribution; moved to readline distribution lib/readline/doc/history.3 - man page for history library; neither built nor installed (part of the standalone readline distribution) lib/readline/histfile.c - changed history_truncate_file to return 0 on success, errno on failure - changed history_do_write to return errno on a write error. This affects write_history and append_history lib/readline/history.c - max_input_history is now history_max_entries; the old variable is maintained for backwards compatibility lib/readline/histexpand.c - the list of delimiters that separate words for history_tokenize is now a variable: history_word_delimiters; default value is as before - changed history_expand to return 0 immediately if its second argument is NULL bashline.c - changed to use history_max_entries lib/readline/history.h - extern declaration for history_max_entries - extern declaration for history_word_delimiters 3/8 --- test.c - changed unary_operator() to return FALSE for non-numeric arguments to `-t' 3/9 --- [bash-2.05-beta2 released] 3/12 ---- lib/readline/doc/rltech.texinfo - documented rl_set_paren_blink_timeout() - moved the example function to its own info node lib/readline/{hstech.texinfo,history.3} - `$' is not in the default value of history_word_delimiters 3/13 ---- bashline.c - in maybe_add_history, if the tests for HISTCONTROL succeed, but the HISTIGNORE check fails, set first_line_saved to 0 3/15 ---- lib/glob/fnmatch.c - fixed a bug in patscan that caused `[' to be treated as special even inside a nested bracket expression. It's supposed to lose it's special handling inside [] - fixed a bug in patscan that caused `]' to end an embedded bracket expression even if it was the first character after the `[' (or a leading `!' or `^') 3/22 ---- execute_cmd.c - made a small change to shell_execve to report a more user-friendly error if execve(2) fails because of a `#! interpreter' error with `interpreter' - in shell_execve, if HAVE_HASH_BANG_EXEC is not defined, make sure the file length is > 2 characters before attempting to execute an interpreter 3/26 ---- jobs.c, nojobs.c - give_terminal_to now takes a second argument, FORCE. If that second argument is non-zero, give the terminal away no matter what job_control is set to jobs.h - changed extern declaration of give_terminal_to {jobs,sig,subst}.c,parse.y - changed all calls to give_terminal_to to add a second argument of 0 jobs.c - changed second argument of call to give_terminal_to in end_job_control to 1, to force this even if job_control is 0. This fixes the problem of `exec other-job-control-shell' in a startup file hanging, since run_startup_files sets job_control to 0 subst.c - fixed test of subshell_environment in command_substitute to test the bit SUBSHELL_ASYNC rather than test equality, since it's now a bitmask 3/27 ---- shell.c - changed posix initialization calls to set POSIXLY_CORRECT=y and then call sv_strict_posix, so $SHELLOPTS includes `posix' and POSIXLY_CORRECT is set, for both the posix command line options and when act_like_sh is non-zero redir.c - the `>& filename' redirection now works in posix mode, redirecting stdout and stderr, since POSIX.2 leaves it unspecified doc/bashref.texi - removed item about `>& filename' from Bash POSIX Mode section parse.y - fixed a problem in decode_prompt_string with `\W' not printing anything if PWD == "//" lib/readline/input.c - in rl_read_key, after calling (*rl_event_hook), check for rl_done being set, and return '\n' if it is Makefile.in - changed RELSTATUS to `release' 3/28 ---- support/bashbug.sh - replace use of $(...) with `...` for the benefit of old versions of sh builtins/set.def - changed print_all_shell_variables to not print shell function names and definitions when in posix mode doc/bashref.texi - noted change in `set' behavior in posix mode section 4/2 --- lib/readline/readline.c - changed default value of RL_LIBRARY_VERSION to `4.2' 4/5 --- [bash-2.05-release frozen]
