8 - don't automatically use GNU malloc on FreeBSD, the builtin one
9 is supposed to be better (but doesn't have the debugging hooks)
12 - check that full_pathname(command) doesn't return NULL because of
13 inaccessible parent directories
19 - broke the code that opens a file for output redirection when in
20 noclobber mode out into a separate function: noclobber_open().
21 This tries to avoid race conditions and file replacement between
25 - make sure pat_subst does not run off the end of its return
26 string when copying the unmatched portion of the input string
31 - don't install readline.3 by default
34 - removed an unnecessary check for string[i] being non-null in
39 support/config.{sub,guess}
40 - merged in changes from config.sub in autoconf-2.12 distribution
42 lib/readline/readline.c
43 - in rl_newline, only call _rl_vi_done_inserting and _rl_vi_reset_last
44 if readline is currently in vi mode
46 lib/readline/display.c
47 - corrected a misuse of inv_lbreaks where vis_lbreaks was wanted in
48 the code that decides whether the cursor is at the beginning of
49 an otherwise-empty line
54 - fixed a typo, thanks to eggert@twinsun.com
57 - new test, BASH_STRUCT_DIRENT_D_FILENO, testing for d_fileno member
61 - call BASH_STRUCT_DIRENT_D_FILENO
64 - new #define for STRUCT_DIRENT_HAS_D_FILENO
66 lib/posixheaders/posixdir.h
67 - only define d_fileno as d_ino if STRUCT_DIRENT_HAS_D_INO is defined
68 and STRUCT_DIRENT_HAS_D_FILENO is not defined. This fixed the
69 problem of compiling getcwd.c on SunOS4.1.4 with cc
73 lib/readline/complete.c
74 - fix a memory-used-after-freed bug reported by Andreas Schwab
77 - call BASH_CHECK_SOCKLIB only if getpeername is not found in libc
78 (ac_cv_func_getpeername = no)
84 - change #define guard to _SH_GETOPT_H to avoid similar guards in
85 /usr/include/getopt.h (Dec OSF/1 4.x, for example)
88 - fix assign_array_from_string so that it rejects attempts to assign
92 - fix verify_substring_values to handle offsets that are past the
93 end or before the beginning (in the case of a negative offset)
94 of the expanded variable value
99 - fix a problem where any completion after a `cmd` command
100 substitution would inappropriately attempt command completion,
101 even if the previous command substitution was correctly closed
103 builtins/evalstring.c
104 - unwind_protect remember_on_history even if the shell is not
105 interactive, since history can now be used in scripts, and
106 `source' will turn off interactive_shell before calling
110 - new function get_job_by_pid(pid, block) to translate a pid to
111 a job number. The block argument says whether or not to block
115 - new extern declaration for get_job_by_pid
118 - call get_job_by_pid if an argument appears to be a pid rather
122 - configure --without-gnu-malloc automatically on MachTen 4.x
125 - change to mindist() so that a best guess of `.' returns 3,
126 which means not reasonable
128 lib/posixheaders/memalloc.h
129 - changed hpux_9 to __hpux, since the new config stuff doesn't
133 - fix parameter_brace_patsub to handle null patterns (doesn't
137 - slight change to bzero replacement
140 - changed TEMP to be /tmp/bbug.$$ as a sop to systems with 14-char
144 - add note to POSIX Mode section that the output of `set' when
145 invoked without arguments is sorted when in POSIX mode
150 - a couple of changes prompted by a `gcc -Wall'
153 - changed ASSIGN_RETURN macro to use the do...while(0) idiom to
154 avoid problems with its multiple statements
157 - a bad identifier given to readonly or export without an assignment
158 statement (e.g. `readonly a[5]') is an error, but not an assignment
159 error (i.e., return EXECUTION_FAILURE rather than EX_BADASSIGN)
161 tests/{{array,new-exp}.,tilde-}tests
162 - added `set +o posix' at the beginning to disable POSIX mode, which
163 causes some of the tests to fail. Some systems (e.g. LINUX-FT),
164 set POSIXLY_CORRECT by default
167 - added a warning if $UID is 0 to the effect that the test suite
168 should not be run as root
169 - worked around the `noread' and `nowrite' tests failing when run
173 - began removing the remains of the STANDALONE code, since test is
174 included in GNU shellutils
178 lib/readline/{readline,display}.c
179 - a couple of slight changes to build on Win95 using djgpp (reported
180 by x-aes@telelogic.se)
183 - changed TERMCAP_LIBDIR to TERM_LIBDIR, so building the termcap
184 library (if necessary) should work now
187 - new function: quote_word_break_characters(), to backslash-quote
188 characters in a filename that the readline completion code would
190 - change bash_quote_filename to call quote_word_break_characters if
191 the completion quoting style says to use backslashes
192 - add `:' to rl_filename_quote_characters, since it's part of
193 filename_word_break_characters
195 lib/posixheaders/posixjmp.h
196 - new file, with half of bashjmp.h
197 - posixjmp.h and lib/readline/posixjmp.h are symlinks to this file
200 - include "posixjmp.h" for possible redefinitions of setjmp/longjmp
206 - bad options now cause the standard shell usage message (a subset
207 of what `bash --help' prints) to be displayed on stderr
210 - don't free the trap command for a DEBUG trap in
211 restore_default_signal if SIG_INPROGRESS is set -- there's already
212 a pointer saved to the old value in _run_trap_internal. This
213 makes bashdb run better, too
215 examples/bashdb/bashdb.{pre,fns}
216 - a couple of minor fixes; it actually has a chance of working now
221 - add a define for <dlfcn.h>, HAVE_DLFCN_H
224 - look for <dlfcn.h>, define HAVE_DLFCN_H if found
227 - include <dlfcn.h> only if HAVE_DLFCN_H is defined
229 lib/readline/display.c
230 - renamed clear_to_eol to _rl_clear_to_eol and made it global, so
231 other library files (readline.c) can use it
232 - new function _rl_clear_screen, to clear the screen with the right
233 termcap escape sequence
235 lib/readline/readline.c
236 - call _rl_clear_to_eol and _rl_clear_screen instead of using tputs
237 - extern declarations for _rl_clear_to_eol and _rl_clear_screen
242 - fixed a problem in make_default_mailpath() where a slash was not
243 added between the default mail directory and the username
248 - added a fourth parameter to ansicstr: the length of the returned
252 - changed declaration of ansicstr
255 - changed call to ansicstr -- saves a call to strlen
258 - changed call to ansicstr
259 - if do_v9 is non-zero, use putchar to output the string instead
260 of printf, since there may be embedded NULL characters
262 doc/{bash.1,bashref.texi}, builtins/trap.def
263 - modified the `trap' documentation to make it clearer that trap
264 takes multiple signal specs as arguments
266 jobs.c, nojobs.c, jobs.h
267 - renamed initialize_jobs to initialize_job_control, added an
271 - set shell_tty to fileno(stderr) in initialize_job_control if
272 the shell is not interactive. This fixes the problem of bad
273 tty pgrps when monitor mode is turned on in a non-interactive
277 - made initialize_terminating_signals do only that; moved the rest
278 of the code that used to be there into a new function:
279 initialize_shell_signals, which calls initialize_terminating_signals
280 if the shell is interactive
281 - initialize_terminating_signals is now extern
282 - made reset_terminating_signals return immediately if
283 termsigs_intitialized is zero, meaning that
284 initialize_terminating_signals has not been called
287 - new extern declaration for initialize_terminating_signals
290 - call initialize_terminating_signals from set_signal if sig is
291 EXIT_TRAP and the shell is not interactive. Since the terminating
292 signals do not need to be initialized until a trap on exit is
293 set, not doing that at startup should result in a speed increase
297 - save and restore command->flags in time_command, so you can use
298 `time command' in a loop
302 lib/readline/display.c
303 - fix redisplay code to wrap correctly if the prompt is longer than
304 the screen width (reported by bos@Eng.Sun.COM)
307 - don't include <setjmp.h>, it's not needed
309 lib/readline/{util,readline}.c
310 - include "posixjmp.h" instead of <setjmp.h>
311 - readline_top_level is now a `procenv_t' instead of a `jmp_buf'
312 (now readline uses the correct posix semantics for preserving
313 the signal mask and other things across longjmp)
316 - fixes to push_string/pop_string to make them more general -- they
317 now can be used generally, instead of having to be associated
318 with an alias being expanded
319 - fixes to the parser so that it parses (( ls abc; ls def); ls ghi)
320 as a nested subshell command for backwards compatibility. Broke
321 the double-paren expression parsing off into a new function:
322 parse_arith_cmd, called from read_token when a `((' is seen. If
323 it looks like an arithmetic command, return `let' and set things
324 up so that the expression is returned as a double-quoted string
325 by the next call to read_token. If it's a nested subshell, push
326 the text we parsed onto the list of strings for later consumption
330 - fix glob_vector so it doesn't short-circuit checking a filename if
331 it starts with a `.' and the pattern starts with `\.' (if
332 noglob_dot_filenames is set). This makes `".junk2"*' match
333 `.junk2.txt' correctly
338 - ask for confirmation before sending the bug report
341 - when editing and re-executing a multiline command, make sure
342 current_command_line_count is initialized and then incremented
343 for each line read from the file so that the lines added to
344 the history list by fc_replhist and fc_addhist obey the `lithist'
345 and `cmdhist' shopt options. Reported by tibbitts@pb.seflin.org
349 lib/readline/readline.h
350 - added a couple of extern declarations for variables described in
351 the documentation but heretofore undeclared
354 - try to catch some classes of integer overflows before calling
360 - push and pop a `(' delimiter while parsing a $(...) construct, so
361 the history code doesn't try to inappropriately add a `;' when
362 a newline appears in the `...'
365 - new macro, BASH_STRUCT_WINSIZE, which looks for `struct winsize'
366 in <sys/ioctl.h> (or one of the files it includes)
369 - call BASH_STRUCT_WINSIZE
370 - slightly reorganized the calls to bash-specific macros
373 - add an `#undef STRUCT_WINSIZE_IN_SYS_IOCTL'
376 - only look in sys/ptem.h for struct winsize if
377 STRUCT_WINSIZE_IN_SYS_IOCTL is not defined to cpp
381 .{distribution,patchlevel}
382 - renamed to _{distribution,patchlevel}
385 - create a variable BASHVERS, from the contents of _distribution,
386 and a variable BASHPATCH, from the contents of _patchlevel,
387 (using m4 magic so we don't have to distribute .distribution
388 and .patchlevel) and substitute them into Makefile.in
391 - use Version and PatchLevel variables instead of the contents of
392 .distribution and .patchlevel, respectively. These are set by
394 - removed `.machine' from targets and dependencies
397 - new shell script to handle updating version.h, replaces mkversion.c
398 (which is now overkill)
401 - don't bother with writing .distribution and .patchlevel files,
402 since they're no longer distributed
405 - simple bash script to make new version files. It can increment
406 the major or minor version numbers or patchlevel, or take a
407 completely new version number (e.g., 2.01) as an argument
410 - added support for the `install-info' command to update the info
411 directory file after installing bash.info
416 - fix core dump with `help --'
419 - make call_expand_word_internal obey the convention that if
420 expand_word_internal returns &expand_word_{fatal,error}, then
421 w->word has already been freed
422 - return &expand_word_fatal from expand_word_internal if the shell
423 is not interactive and `set -u' has been executed
426 - moved group_member from test.c to general.c
429 - moved extern declaration of group_member from externs.h to general.h
432 - broke the code that initializes the group array out into a new
433 function, initialize_group_array()
434 - initialize_group_array() now initializes an array even if the OS
435 does not have getgroups(). If it does not, an array with one
436 element (the real gid) is created
437 - call sysconf(_SC_NGROUPS_MAX) if sysconf is available and
438 _SC_NGROUPS_MAX is defined
439 - new function, char **get_group_list(int *), to return an array
440 of strings made from the groups list
443 - new dynamic array variable: GROUPS, expands to the group set as
444 obtained with getgroups() (or whatever initialize_group_array()
447 doc/{bash.{1,html},bashref.texi}
448 - added description of GROUPS variable
451 - before modifying the setgid bit on /tmp/setgid, try to change its
452 group to ${GROUPS[0]}
457 - new autconf macro, BASH_MISC_SPEED_T, to see if speed_t is defined
461 - call BASH_MISC_SPEED_T
464 - add `#undef SPEED_T_IN_SYS_TYPES'
467 - include `rltty.h' if HAVE_TERMCAP_H and __linux__ are defined, but
468 SPEED_T_IN_SYS_STYPES is not, before including <termcap.h>
470 support/mksignames.c, siglist.c
471 - add support for 4.4 BSD SIGLOST
474 - add support for recognizing QNX based on `uname' output
477 - make sure recho and zecho are compiled with the same set of CC
478 options as the rest of the sources
481 - change calls to rl_generic_bind to cast the third argument to
482 (char *) where necessary
485 - two new flags: CMD_AMPERSAND (currently unused), and CMD_STDIN_REDIR,
486 which means that this command should have its standard input
487 redirected from /dev/null if there are not any explicit redirections
491 - a redirection of type r_inputa_direction is no longer added at the
492 beginning of the redirection chain for an async command;
493 CMD_STDIN_REDIR is set in the flags instead
494 - new function: stdin_redirects: returns the number of redirections to
495 stdin in a chain of redirections
496 - new functions: async_redirect_stdin() to open /dev/null and make it
498 - changes to make CMD_STDIN_REDIR propagate to all of the necessary
499 functions (like execute_simple_command)
500 - execute_disk command now takes the flags from simple_command rather
501 than just the CMD_NO_FORK flag as its last argument
502 - various places after make_child is executed (in the child) check for
503 CMD_STDIN_REDIRECT (and no stdin redirections or piping) and call
505 - stdin_redir is now global
508 - set stdin_redir to 0 just before calling execute_command so it
509 gets reset to a known value and doesn't persist across commands
514 - add a stub function for ulimit(2) on systems without HAVE_RESOURCE
515 or HAVE_ULIMIT that just sets errno to EINVAL and returns -1 --
516 QNX is one such system
519 - pre_process_line needs to protect all occurrences of hist_verify
523 - hist_verify needs to be protected with #ifdef READLINE, not
528 support/config.{guess,sub}, configure.in
529 - chages to better support the Harris Night Hawk
532 - changes for things pointed out by gcc -Wall
535 - make sure -DSHELL is included in CCFLAGS so that globbing is
539 - extern declaration for botch: if botch is #defined, it should be
540 the name of a void function
542 configure.in,Makefile.in,builtins/Makefile.in,
543 lib/{glob,malloc,readline,tilde}/Makefile.in
544 - add a LOCAL_DEFS variable, substituted from configure into the
545 various Makefiles. It's set to -DSHELL, so that define gets
546 passed to all sub-makes without doing anything special
548 lib/readline/readline.c
549 - change to rl_digit_loop to make it compatible with GNU emacs:
550 if a key bound to `universal-argument' is read after reading
551 some digits, it terminates the argument but is otherwise
552 ignored. This is how people can insert repeated digits
554 doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo
555 - changed description of `universal-argument' to describe how
556 to terminate a numeric argument
561 - changed kill_pid to diddle the job and process data structures
562 if we're sending SIGCONT to a stopped job with `kill' so that
563 the shell knows the job is running again. ksh93 does this
568 - changed bcopy to FASTCOPY
571 - changed pointer arithmetic in delete_builtin to just subtract
572 the head of the builtins list (shell_builtins) from a pointer
573 to the builtin to be deleted (b) to find its index in the list
579 - when using old-style keynames to bind to a new-style macro,
580 pass an array of type (unsigned char *) to rl_macro_bind
583 - change sh_getopt to return EOF if nextchar is empty or NULL
584 and sh_optind is greater than argc. This can happen if a
585 script mixes calls to `getopts' with calls to `shift'
590 - fixed make_command_string_internal so that commands with the
591 CMD_TIME_POSIX flag set print `time -p' instead of `time'
592 - changed print_redirection_list so the here documents are
593 printed after all the other redirections, and followed by a
594 newline (rather than a possible semicolon)
595 - added a new variable, was_heredoc, to avoid adding a semicolon
596 at the beginning of an empty line after printing the heredoc
600 - don't put the gnu_argv_flags into the environment any more; it's
601 proven to be a bad idea
604 - set LOCAL_CFLAGS to `-DSunOS5' on Solaris 5.5[.x]
607 - only call fflush() after printing each word on SunOS 5.5, since
608 that's the system with the bug that prompted its inclusion in
612 - added support for more system-specific signals from AIX 4.2,
613 changed initialization order so that system-specific signals
614 are done first, before the common signals
619 - broke the code that creates a file containing the text of a
620 here document out into a separate function: here_doc_to_fd
621 - create the temp file used for a here document with mode 600
622 - open the temp file used for a here document with O_EXCL
625 - changed the uid members of struct user_info to be of type uid_t
626 and the gid members to be of type gid_t
629 - changed the type of the `type' argument to init_yy_io() to be
630 `enum stream_type', since that's what's always passed
633 - changed the function prototype for init_yy_io so the third arg is
634 type `enum stream_type'
637 - added a prototype for getcwd, if HAVE_GETCWD is not defined
640 - changed all variables that are used as arguments to or save the
641 return value from umask(2) to be of type mode_t
642 - changed print_symbolic_umask to take an argument of type mode_t
647 - if old_sigint_handler is set to SIG_DFL, as it will be in a script
648 without a trap on SIGINT installed, call termination_unwind_protect()
649 directly from waitchld()
654 - added a section before the call to BASH_CHECK_LIB_TERMCAP to
655 set a variable prefer_curses on some systems (AIX, for one)
658 - in BASH_CHECK_LIB_TERMCAP, don't return -ltermcap if $prefer_curses
661 lib/readline/Makefile.in
662 - redid the dependencies
667 - include `bashansi.h' instead of stdlib.h and string.h
669 error.c, siglist.c, xmalloc.c, builtins/{common,evalfile,mkbuiltins,psize}.c,
670 builtins/{exec,exit,fg_bg,hash,history}.def
671 - include `bashtypes.h' instead of directly including <sys/types.h>
674 - include ../bashtypes.h and ../posixstat.h instead of bashtypes.h
677 builtins/mkbuiltins.c
678 - include ../posixstat.h instead of <sys/stat.h>
681 - include `bashtypes.h' if RLIMTYPE is defined, so we can fetch
682 a definition of quad_t (or whatever) from <sys/types.h> before
683 using it in a function prototype
685 Makefile.in, builtins/Makefile.in
686 - updated dependencies
691 - new function, set_posix_mode, called when `set [-+]o posix'
692 or `shopt -[su] -o posix' is executed. It sets or unsets
693 $POSIXLY_CORRECT and calls sv_strict_posix
696 - in sv_strict_posix, call posix_readline_initialize only if
697 the shell is interactive (interactive_shell != 0)
700 - if we are acting like `sh', call posix_readline_initialize
701 if the shell is interactive
702 - moved the code that does posix.2 mode initialization after
703 interactive_shell is set, and call posix_readline_initialize
704 if interactive_shell is non-zero
707 - renamed to unionwait.h, since that is what it defines
710 - moved the POSIX 1003.1 job control defines here from jobs.h
713 - include `posixwait.h'
718 - if SHELL is defined, pass the contents of new-style command
719 substitution through without expanding brace constructs between
720 the parens -- let the subshell do it
723 - when brace-expanding words, preserve the flags (word->flags) if
724 brace expansion does not change the word. This fixes the problem
727 local -a avar=( ${PATH//: } );
730 - have shell_expand_line pass a copy of rl_line_buffer to expand_string
731 in case there are substitution errors and the string gets freed
736 - make sure that expland and explor set `lasttok' to LAND and LOR,
737 respectively, if they parse `&&' or `||'. This makes the
738 precedence code work right
741 - changes so that non-interactive shells exit immediately when a
742 parameter that is unset is referenced after `set -u' has been
743 executed causes the shell to exit immediately
748 - if `set -r' is executed, call maybe_make_restricted so that $PATH
749 and $SHELL are made read-only
752 - if `set -e' has been executed, and we're inverting a pipeline's
753 return status with `!', set CMD_IGNORE_RETURN so a failing
754 command does not inadvertently cause the shell to exit before
755 the exit status can be inverted. This is probably only a problem
756 with the `eval' builtin.
761 - add a missing argument of 0 to add_hashed_command
764 - job identifiers can be used in non-interactive shells as long as
765 job control has been turned on with `set -m'
768 - we want to be notified of stopped jobs if job_control is non-zero,
769 even if the shell is not interactive
772 - make sure shell_execve returns EX_NOTFOUND if execve fails and
773 errno is set to ENOENT
774 - makes sure execute_builtin saves the temporary environment to
775 builtin_env for the `eval' builtin, since it can destroy the
776 temporary environment when it calls parse_and_execute
779 - new variable: hist_last_line_added, set to 1 if the last command
780 line was added to the history successfully as a separate entry.
781 Used by `history' and `fc'
786 - save line number before executing trap command, because
787 parse_and_execute resets it to 1 and the trap command might
791 - change to executing_line_number to return trap_line_number if
792 the shell is currently running a trap
797 - change to time_command so that a `real' value of 0 does not
798 cause a divide-by-zero error when computing cpu percentage
800 lib/readline/signals.c
801 - if MUST_REINSTALL_SIGHANDLERS is defined, reinstall the SIGWINCH
802 handler in rl_handle_sigwinch
805 - `unset' now rejects attempts to unset names that are not valid
806 shell identifiers as errors
807 - add a description of `-o history' option to help text
810 - in parameter_brace_patsub, we want backslash removal done on
811 the replacement if (mflags & MATCH_QUOTED), since the code
812 in expand_word_internal will not do it. We need to call
813 expand_string_unsplit directly, since maybe_expand_string does
814 not do the right thing
819 - if execute_for_command finds that the iteration variable is readonly,
820 decrement loop_level before returning
823 - if the break count is <= 0, display an error message and break out
827 - if PATH is unset, and we're using command -p, we don't want PATH
828 to be set to the empty string when `command' completes
831 - POSIX.2 says `kill -l signum' prints the signal name without the
832 leading `SIG' prefix, so check for this_shell_builtin == kill_builtin
833 in display_signal_list
836 - when invoked without any arguments, `getopts' now prints a usage
842 - add a second argument to get_numeric_arg: if non-zero, the shell
843 exits on a bad argument; if not, the shell jumps to top_level
844 with a DISCARD argument, which aborts the current command
846 builtins/{break,exit,history,return,shift}.def
847 - change calls to get_numeric_argument
849 lib/readline/funmap.c
850 - add `dump-macros' to list of bindable names
852 lib/readline/readline.h
853 - added extern declaration for rl_prompt (it was apparently missing)
855 lib/readline/readline.c
856 - new internal function, _rl_init_line_state, which sets rl_point
857 and rl_end to 0, sets the_line to point to _rl_line_buffer, and
860 lib/readline/callback.c
861 - if a user's callback function does not clear the line, clear it
862 for him by calling _rl_init_line_state
867 - made the readline support functions #ifdef READLINE, so they're
868 not compiled into the shell unless readline is
871 - new function _rl_untranslate_macro_value, to expand meta-prefixes
872 and other special characters in a macro value for printing by
873 _rl_macro_dumper_internal
874 - call _rl_untranslate_macro_value in _rl_macro_dumper_internal to
875 get a printable version of the macro value
877 lib/readline/readline.c
878 - new variable, rl_dispatching, set to 1 when we call a function
881 lib/readline/readline.h
882 - extern declaration for rl_dispatching
884 lib/readline/complete.c
885 - make sure S_ISCHR and S_ISBLK are defined before using them
887 lib/readline/terminal.c
888 - add a new #define NEED_EXTERN_PC. Define this if the termcap
889 or curses libraries need `extern' before declarations of PC,
892 lib/readline/{readline,terminal,histfile}.c
893 - changes to compile on OS/2 with OS/2 `EMX' port of gcc, originally
894 sent by ilya@math.ohio-state.edu
897 - fixed a bug in set_shellopts that caused the shell to crash if
898 there were no shell options set
902 configure.in,Makefile.in
903 - choose run-all or run-minimal as the test script based on whether
904 the --enable-minimal-config option was given to configure
907 - fixed `export -p' and `readonly -p' so that they output `export'
908 or `readonly' when in POSIX mode, as POSIX.2 specifies
913 - make `readonly -a var=(...)' work just like `declare -ar var=(...)',
914 since the two logically mean the same
915 - `readonly -f' and `export -f' don't print the function definition
916 for each readonly or exported function, respectively, when in
920 - don't report status for processes killed by SIGPIPE if
921 DONT_REPORT_SIGPIPE is defined
924 - added a commented-out define for DONT_REPORT_SIGPIPE
927 - `time' can now be used to time background pipelines, and reports
928 the timing statistics when the pipeline completes
930 [bash-2.01-alpha1 frozen]
935 - move the parent end of the pipe file descriptor used for process
936 substitution to a high, unused file descriptor to avoid clashes
937 with redirections performed explicitly by a script
940 - added a `--with-curses' argument so curses can be forcibly chosen
941 over libtermcap (some Unix versions ship lousy termcap databases)
944 - new script to create _distribution and _patchlevel from values
945 contained in `configure'
948 - updated installation instructions
953 - if `getgroups' returns 0, make sure we add the primary group id
955 - if we have getgroups, and the primary gid is not in the array
956 getgroups returns, add it as group_array[0] and shuffle everything
957 up one element. This ensures that current_user.gid == group_array[0]
961 - changes to avoid stray variables in environment when the shell
962 version of printenv is used with bash as /bin/sh, running the
968 - spelling correction is no longer enabled by default
971 - if the shell's release status is alpha or beta, offer the option
972 of sending the bug report to the bash-testers mailing list as
978 - configure --without-gnu-malloc by default on *-sgi-irix6* because
979 their code needs 8-byte alignment
982 - ``' needs to be quoted with a backslash in double-quoted strings
985 - slight changes to the strcoll test, since AIX 4.2 returns -1, 0, or
986 1 from strcmp(3) but a numeric collation order difference from
992 - new redirection error code: HEREDOC_REDIRECT
995 - return HEREDOC_REDIRECT from do_redirection_internal when
996 here_document_to_fd cannot create the temp file for a here document
997 - changed redirection_error to print a meaningful message when
998 here document temp file creation fails (HEREDOC_REDIRECT)
1003 - changes to match_pattern_char: return 1 if the first char of the
1004 pattern is `?' only if the string is non-null; just return 1 if
1005 the first char of the pattern is `[' and the string is non-empty
1006 rather than try to re-implement the brace matching code from fnmatch
1009 - some changes from glibc-2.0.1 posix/fnmatch.c
1014 - only do the initialization of `ignoreeof' if the shell is
1016 - reset values of $SHLVL > 1000 to 1 in adjust_shell_level, and
1017 don't call itos, since we don't need its generality
1018 - new function, initialize_shell_level, just calls adjust_shell_level
1019 with argument of 1. If $SHLVL is unset, adjust_shell_level will
1020 deal with it correctly
1021 - change initialize_shell_variables to not malloc a copy of each
1022 environment variable, just keep two pointers into the env string:
1023 one for the name, one for the value
1024 - broke the code that computes the value of $BASH out into a separate
1025 function: get_bash_name
1026 - get_bash_name special-cases shell_name with a `./' prefix when
1028 - new function: set_home_var, sets $HOME to current_user.home_dir if
1029 it's not already set, calling get_current_user_info if
1030 current_user.home_dir is NULL
1031 - new function: set_shell_var, sets $SHELL to current_user.shell if
1032 it's not already set, calling get_current_user_info if
1033 current_user.shell is NULL
1034 - changed places that reference information in current_user to check
1035 for NULL values of the member they're interested in and call
1036 get_current_user_info if necessary
1039 - moved the code that sets up the information in current_user that
1040 comes from the password file into a new function,
1041 get_current_user_info
1042 - shell_initialize calls get_current_user_info only if the shell is
1046 - new extern declaration for get_current_user_info(), so variables.c
1052 - if SHELL is defined, user the current_user struct info to find
1053 the user's home directory rather than calling getpwuid
1058 - don't try to open /dev/tty when getting or setting the tty state
1059 and window size; use shell_tty instead
1060 - initialize shell_tty to standard error in initialize_job_control
1061 - only fetch the tty state initially if the shell is interactive
1064 - open /dev/tty with the O_NONBLOCK flag
1067 - changed all_vars so that it sorts its output all the time, not
1068 just when in POSIX mode. This means that the output of `set'
1069 and `export' will be sorted
1072 - in initialize_shell_options, only call parse_shellopts if we
1073 inherited $SHELLOPTS from the environment
1074 - make sure we call parse_shellopts from initialize_shell_options
1075 with a copy of the value of SHELLOPTS, in case one of the functions
1076 called while setting one of the variables modifies $SHELLOPTS
1078 lib/readline/readline.c
1079 - make sure that digit arguments don't change the state of
1083 - new file, printenv(1) clone, used to avoid environment variables
1084 that might be set automatically when using printenv.sh
1087 - if SHELL is defined, don't call getenv to get the value of $HOME,
1088 call get_string_value () directly
1092 lib/readline/histexpand.c
1093 - abstracted the `#ifdef SHELL' stuff that checked for special cases
1094 that should not be history expanded ([!...], ${!...}) into a call
1095 to a function that is the value of the
1096 new history_inhibit_expansion_function variable
1098 lib/readline/history.h
1099 - extern declaration for history_inhibit_expansion_function
1102 - new function, bash_history_inhibit_expansion, which checks for
1103 the special cases in which history expansion should be inhibited
1104 - changes to the various history initialization functions to
1105 set history_inhibit_expansion_function
1107 lib/readline/doc/hstech.texinfo
1108 - documented history_inhibit_expansion_function
1110 lib/readline/shell.c
1111 - new file, containing versions of the functions that are provided
1112 by bash when readline is linked as part of bash
1113 - new function: get_env_value(). If SHELL is defined, this calls
1114 get_string_value(). If SHELL is not defined, this calls getenv()
1116 lib/readline/histexpand.c
1117 - moved single_quote() to shell.c
1120 - moved savestring() to shell.c
1122 lib/readline/terminal.c
1123 - moved set_lines_and_columns() to shell.c
1125 lib/readline/Makefile.in, Makefile.in
1126 - added shell.c and shell.o to the appropriate variables that contain
1127 the files comprising the readline and history libraries
1129 lib/readline/signals.c
1130 - introduced two new cpp defines: HANDLE_JOB_SIGNALS and
1131 HANDLE_SIGTERM. When HANDLE_JOB_SIGNALS is defined, SIGTSTP,
1132 SIGTTIN, and SIGTTOU are caught and handled. When HANDLE_SIGTERM
1133 is defined, SIGTERM is caught and handled. These are both
1134 defined automatically if SHELL is not defined
1136 lib/readline/{bind,histfile,nls,readline,terminal}.c
1137 - call get_env_value instead of getenv(). This should remove the
1138 dependency on being able to redefine getenv() in oslib.c
1141 - added a missing argument of -1 to the call to list_minus_o_opts.
1142 Now `bash -o' lists all options, not just random ones depending
1143 on what's on the stack
1148 - change RLIM_INFINITY to the hard limit only if the hard limit is
1149 greater than the current (soft) limit
1152 - return immediately from flush_hash_table if the hash table passed
1158 - remove call to initialize_filename_hashing -- initialize the hash
1159 table the first time a hashed command has to be remembered
1162 - new file, with functions to perform filename hashing and lookup
1163 taken from builtins/hash.def and builtins/common.c
1164 - change to remember_filename -- call initialize_filename_hashing
1165 if hashing_initialized is 0
1168 - new file, mostly from builtins/hashcom.h, with extern function
1171 execute_cmd.c, builtins/{hash,type}.def
1172 - include hashcmd.h for hash function and type definitions
1174 builtins/{common.{c,h},hash.def}
1175 - moved hashing functions and declarations to hashcmd.c/hashcmd.h
1177 Makefile.in, builtins/Makefile.in
1178 - changed source and object file definitions and dependencies because
1179 of addition of hashcmd.h and hashcmd.c
1182 - return immediately from print_hashed_commands if hashed_commands
1183 is empty, indicating that the hash table has not been initialized
1188 - fixed translation of ESC in rl_untranslate_keyseq and
1189 rl_untranslate_macro_value
1191 lib/readline/{readline,kill}.c
1192 - added an argument to _rl_fix_point telling it whether or not to
1193 fix up the mark also; changed calls to _rl_fix_point to add the
1194 appropriate argument
1197 - changed the substitution delimiter in the `sed' commands that
1198 create bashbug from `:' to `%' to avoid conflicts with options
1204 - made the initial value and the default growth value for the
1205 printed command somewhat smaller -- we don't really need to
1206 allocate 4096 bytes for the printed command
1207 - added stdarg support to xprintf if PREFER_STDARG is defined
1210 - changed strip_trailing to take the index of the last character
1211 as the second argument, saving a (useless) call to strlen, since
1212 the caller already knows where the end of the string is
1215 - change call to strip_trailing in command_substitute to add the
1219 - changed extern declaration for strip_trailing
1223 Makefile.in, configure.in, lib/malloc/Makefile.in
1224 - changed the strategy for picking which `malloc' to include by
1225 having configure define a `malloc target' and the Makefile in
1226 lib/malloc implementing rules for that target
1231 - slightly changed the rules for remaking `parser-built': it is
1232 now a copy of y.tab.h, updated only when the contents of y.tab.h
1234 - everything that used to depend on y.tab.h now depends on
1239 execute_cmd.c, print_cmd.c
1240 - use #include <y.tab.h> so we pick up y.tab.h from the build
1241 directory instead of the source directory if it happens to be
1242 recreated in the build directory
1247 - fixed another problem with `pwd`/[TAB] thinking that the `/
1248 started an unclosed command substitution, generating errors
1253 - renamed bash_tilde_expansion_failure_hook to be
1254 bash_special_tilde_expansions, since that more accurately reflects
1256 - changed tilde_initialize so that there is no failure hook -- the
1257 special expansions are handled first with the preexpansion hook
1260 - new variable: tilde_expansion_preexpansion_hook -- if non-null, it
1261 points to a function that is called before standard tilde expansion
1265 - extern declaration for tilde_expansion_preexpansion_hook
1267 doc/{bash.{1,html},bashref.texi}
1268 - added optional open paren to description of `case' command syntax
1273 - on qnx, set and export a variable `NODE' which contains the QNX
1277 - QNX system can now handle pathnames with a leading `//'
1280 - added `-Dqnx' to LOCAL_CFLAGS on QNX machines
1282 lib/malloc/getpagesize.h
1283 - some systems need sysconf(_SC_PAGE_SIZE) to obtain the page size;
1284 added code to check for it
1289 - include the prototype for cprintf only if PREFER_STDARG is defined,
1290 otherwise just have a K&R-style forward function declaration
1293 - reduced the default number of buckets in a hash table to 53
1296 - prime the result string in tilde_expand by allocating a new string
1297 that's as long as the input string (+16 if a tilde appears in
1298 the string to be expanded). This should reduce the number of
1302 - broke the code that reads the output of a command substitution
1303 through the pipe to the subshell out into a separate function:
1304 read_comsub(). This does not use stdio, but rather reads
1305 directly from the pipe into a local 128-character buffer
1310 - some systems need both <sys/time.h> and <time.h>, so include both
1311 if it's possible, otherwise include <sys/time.h> (if present)
1313 lib/readline/rl{tty,defs}.h
1314 - moved includes of <sys/stream.h>, <sys/ptem.h>, etc. to rltty.h
1316 lib/readline/terminal.c
1317 - include rltty.h after rldefs.h
1320 - changes to make environment creation faster and use less memory
1321 (fewer malloc/free calls, too):
1323 o two new variables: export_env_index (how many environment
1324 strings are in export_env) and export_env_size (the
1325 number of slots for strings allocated in export_env)
1326 o added new function add_to_export_env, since adding the
1327 exported shell variables and shell functions does not
1328 need to search the export_env for a definition to supersede
1329 (we just cleared it out!)
1330 o renamed add_or_supersede to add_or_supersede_exported_var,
1331 since it always works on export_env, and changed the second
1332 argument to a flag saying whether or not to allocate a new
1333 copy of the string placed into the environment
1334 o changed calls to add_or_supersede to the new
1335 add_or_supersede_exported_var with the appropriate flags
1336 o don't free and reallocate export_env in maybe_make_export_env,
1337 just free the strings and start anew
1338 o prime the size of export_env from the total number of shell
1339 variables and shell functions -- this will always be enough
1340 for the exported shell functions and variables, and big
1341 enough most of the time for the entire environment
1344 - efficiency hack in bindpwd(): if PWD is exported, we will have to
1345 rebuild the entire exported environment after every time we change
1346 directories. What we do is see if array_needs_making changes value
1347 from 0 to 1 after bind_variable ("PWD", dirname) is called, and
1348 that PWD is exported. If that happens, we just replace the value
1349 of PWD in the exported environment with a call to
1350 add_or_supersede_exported_var
1353 - check calls to pre_process_line to make a fresh copy of the line
1354 if pre_process_line returns what it was passed, in preparation
1358 - pre_process_line now returns its argument if it did not make
1362 - free the bucket entry holding the alias to be removed in
1363 remove_alias, as well as the data
1368 - if an unwind-protect frame is being discarded, and its cleanup
1369 function is `restore_variable', the `arg' member points to a
1370 SAVED_VAR that must be freed. This change is made in
1371 remove_unwind_protect_internal and unwind_frame_discard_internal
1374 - need to free memory allocated by parse_arith_cmd if it is an
1375 arithmetic command, after using it to make a new word
1378 - fixed some memory leaks caused by not freeing the argument to
1379 make_bare_word, which duplicates its string argument
1380 - need to dispose list generated by list_rest_of_args in
1381 paramter_list_remove_pattern
1382 - make sure the return value from getpattern() is freed
1383 - make sure array_value_internal always returns newly-allocated
1385 - get_var_and_type returns a new type: VT_ARRAYMEMBER if the
1386 string passed is of the form var[index]
1387 - make sure parameter_brace_substring frees the memory allocated
1388 by get_var_and_type if verify_substring_values returns 0
1390 hashlib.c, hashlib.h
1391 - new function, dispose_hash_table (table), which frees the
1392 table's bucket array and the table itself
1395 - call dispose_hash_table from delete_all_aliases instead of just
1399 - make sure to free `newnames' (but *not* its contents) before
1400 returning from ignore_globbed_names
1403 - make sure the argv created to pass to shell_execve is freed if
1404 the execve fails and we're not exiting on failed execs
1407 - broke evalexp into two functions: evalexp, which sets up the
1408 jmp_buf that errors jump to, and subexpr, which does the
1409 evaluation and pushing and popping of contexts
1410 - readtok now calls subexpr to evaluate subexpressions in
1412 - evalexp now takes an additional paramter, a pointer to an int.
1413 If the expression contains errors, the location to which this
1414 points gets 0, otherwise it gets 1 to show that the value
1415 returned may be used. This plugs up memory leaks that were
1416 the result of evalexp() longjmping back to top_level
1417 - fixed a memory leak: expr_stack[0] was not being freed
1420 - changed extern declaration for evalexp
1422 variables.c, subst.c, builtins/let.def
1423 - changed calls to evalexp appropriately. They either cause a
1424 longjmp (top_level, DISCARD) (which is what the old stuff in
1425 expr.c did) or are handled by returning an appropriate error
1426 value (e.g., &expand_word_error in subst.c)
1431 - make sure to free dollar_vars[0] before assigning it the first
1432 argument following `-c command'
1435 - if unsetting a local variable with a previous context, make sure
1436 to free the hash table element used to store the local variable
1438 lib/readline/terminal.c
1439 - rearrange the includes so <sys/ioctl.h> is included before rltty.h,
1445 - new function: reset_shell_flags, which resets all of the flags
1446 back to their initial values
1449 - extern declaration for reset_shell_flags
1452 - new function: reset_shell_options, which resets all of the -o
1453 options that are not also shell flags back to their initial values
1456 - new function: reset_shopt_options, which resets all of the shopt
1457 options that are not also shell flags or -o options back to their
1461 - extern declarations for reset_shell_options and reset_shopt_options
1464 - broke the code that reinitializes things when an executable script
1465 without a leading `#!' is found out into a new function:
1467 - initialize_subshell now calls the reset_* functions that reset the
1468 shell flags and options
1470 general.c, general.h
1471 - move_to_high_fd now takes a third argument: the highest fd at which
1472 to start looking. If that's less than 20, the maximum number of
1473 open files as returned by getdtablesize() is used (which is what
1476 jobs.c, shell.c, subst.c
1477 - changed calls to move_to_high_fd appropriately
1479 [bash-2.01-beta1 frozen]
1484 - itos now uses a local char buffer to do its conversion, but still
1485 returns newly-allocated memory
1490 - be a little more careful when checking for backwards-compatibility
1491 with exported function definitions
1496 - translate RLIM_INFINITY to limit.rlim_max if the current limit is
1497 less than or equal to the hard limit, not just strictly less than
1498 (the change of 3/28 was too drastic)
1503 - fixed definition of to_lower on machines without strcasecmp
1506 - don't free the trap command in change_signal if the SIG_INPROGRESS
1507 is set in the signal's flags -- it will cause memory to be freed
1508 twice if a trap command resets the signal handler more than once,
1509 and _run_trap_internal keeps a pointer to the trap command so it
1510 can free it, so there will be no leaks
1514 aclocal.m4,configure.in
1515 - removed BASH_CC_WORKS, since AC_PROG_CC now has the functionality
1518 - get_current_user_info is now a void function
1521 - alias_expand_line_internal was removed
1522 - new function, alias_expand_line, performs alias expansion on
1523 rl_line_buffer and either replaces rl_line_buffer or signals
1525 - new bindable commands: alias-expand-line and
1526 history-and-alias-expand-line, available if ALIAS is defined
1530 Makefile.in, lib/malloc/malloc.c
1531 - changed the define that turns on malloc range checking from
1532 `rcheck' to `RCHECK'
1534 lib/readline/isearch.c
1535 - fixed a couple of places where rl_search_history would try to
1541 - fixed a problem with saving a variable that is a null pointer
1542 in unwind_protect_var. It happens only on machines where the
1543 size of a pointer is not the size of an int. The old FASTCOPY
1544 code would copy the eight bytes at memory location zero, which
1545 did not necessarily make a null pointer
1550 - run_startup_files should turn off job control, since the startup
1551 files should be run without job control enabled -- this makes
1552 SIGINT interrupt startup file execution again
1553 - if we get a SIGINT or other longjmp to top_level while executing
1554 the startup files, re-enable job control for interactive shells
1555 before setting locally_skip_execution
1560 - if we have setlocale(3), don't bother with checking the
1561 environment variables for valid values; just use setlocale()
1562 to set the locale categories from the environment variables
1563 directly and go into eight-bit mode if the current locale is
1569 - make sure that the handler for SIGPROF is not changed if it has
1570 been set to something other than SIG_IGN or SIG_DFL -- this makes
1571 profiling work after the terminating signals have been initialized
1574 - if a filename containing `!' is completed, and the user has started
1575 the string with a `"', change the completion style to backslash-
1576 quoting, since there's no way to use `!' with double quotes (this
1577 requires more changes to readline to really work right)
1581 lib/readline/complete.c
1582 - changes to make_quoted_replacement, insert_all_matches, and
1583 insert_match and their callers to allow the application-specific
1584 filename quoting function to change the quote character (e.g., for
1585 bash to change a filename containing a `!' and started with a
1586 double quote by the user into a filename with the `!' quoted by
1587 a backslas and no double quote)
1592 - new function: nohup_all_jobs(), calls nohup_job for each entry in
1594 - delete_all_jobs is now global
1597 - new extern declarations for delete_all_jobs() and nohup_all_jobs()
1600 - `disown' without any jobspec arguments means the current job. Fix
1601 a core dump printing the error message when there is no current job
1606 - process an expansion like $((foo); bar) as a command substitution,
1607 not as an arithmetic expansion. An arithmetic expansion must have
1612 builtins/evalstring.c
1613 - the third argument to parse_and_execute() is now a flags word.
1614 The caller can control the value of `interactive' and whether
1615 or not history is disabled while parse_and_execute() runs
1618 - new #defines for the flag values for parse_and_execute()
1620 {bashline,jobs,shell,subst,trap,variables}.c, parse.y, builtins/evalfile.c,
1621 builtins/{eval,fc}.def
1622 - changed calls to parse_and_execute appropriately
1625 - if _evalfile() is passed FEVAL_HISTORY as part of the flags arg,
1626 don't pass SEVAL_NOHIST to parse_and_execute
1627 - new function: fc_execute_file, which sets FEVAL_HISTORY in the
1628 flags argument to _evalfile()
1631 - call bash_add_history instead of add_history from
1632 vi_edit_and_execute_command so the bash state variables get
1633 updated properly. This keeps the `v' command from operating
1634 on an empty command when the history list is stifled
1637 - bash_add_history is now global
1640 - extern declaration for bash_add_history
1643 - call fc_execute_file instead of maybe_execute_file in the
1644 edit-and-re-execute case (fc -e ...)
1645 - don't manually insert the commands from the file created by `fc -e'
1646 into the history list, just set remember_on_history and let
1647 fc_execute_file take care of telling parse_and_execute to do the
1648 right thing. This makes compound commands and the `cmdhist'
1649 and `lithist' settings work better. This supersedes the fix of
1650 1/27. This was reported again by rchen@fractal.eng.yale.edu.
1653 - the body of a `for' command (the commands between do...done or
1654 {...}) should be a `compound_list' instead of a `list'. Problem
1655 reported by cpg@research.bell-labs.com
1659 lib/readline/complete.c
1660 - in filename_completion_function, if we find that the directory
1661 pointer (return value from opendir(3)), is not null when state
1662 is 0 (indicating that this is the first time the completion
1663 function has been called for the current completion), call
1664 closedir on it, assuming that it was left open by a previous
1665 (interrupted) completion
1667 [bash-2.01-beta2 frozen]
1672 - make sure that `make distclean' (and other clean targets) remove
1673 the `printenv' executable
1675 tests/execscript, tests/redir.tests
1676 - make sure to set LANG=C and LC_ALL=C so the messages show up in
1680 - add a warning about exported functions in the environment
1685 - if one of the arguments passed to `hash' is an absolute pathname,
1686 just continue the loop, don't do list=list->next first. This
1687 fixes the `hash a/b' -> core dump bug
1692 - change canonicalize_pathname to leave a leading `/' alone, as
1697 support/xenix-link.sh
1698 - shell script for linking bash under Xenix
1703 - fixed a memory leak in command_word_completion_function, courtesy
1704 of a.pfaller@pop.gun.de
1707 - fixed find_hashed_filename to always return a newly-allocated
1711 - since find_hashed_filename returns newly-allocated memory, don't
1712 call savestring() on it, and free it if the data is stale (in
1713 search_for_command()). Another memory leak fixed courtesy of
1714 a.pfaller@pop.gun.de
1717 - free the value returned by find_hashed_filename
1719 [bash-2.01-release frozen]
1724 - force shlicc2 and libc malloc for BSD/OS 3.0
1729 - don't create ${man3dir}, since we're not installing the readline
1732 lib/readline/readline.h
1733 - rl_dispatching should be declared `extern'
1738 lib/malloc/Makefile.in
1739 - make sure ${ALLOCA_SOURCE} is preceded by ${srcdir} so that things
1740 work when building in a directory other than the source directory
1745 lib/readline/examples/rltest.c
1746 - don't free the value returned by history_list()
1748 lib/readline/histfile.c
1749 - open the history file for writing with mode 0600 for better
1754 - select_query now uses legal_number to decide whether the user's
1755 selection is a valid number, and just executes the loop again if
1756 invalid input is entered
1761 builtins/evalstring.c
1762 - fix to parse_and_execute so `bash -c 'time [-p] zzz'' works right
1766 - fix to execute_command_internal so that `bash -c time [-p] (zzz)''
1769 - print_formatted_time should pass a long as the fourth parameter
1774 - `exit_shell' is now a void function
1777 - print_table_stats is now a void function
1780 - made add_mail_file check for the filename in the mail file list
1781 using the expanded filename, since that is what it puts into
1786 - for the time being, PWD will be auto-exported, since some systems
1789 doc/bashref.texi, lib/readline/doc/{hist,rlman}.texinfo
1790 - added necessary `dircategory' and `direntry' commands to make
1791 `install-info' work correctly
1794 - move $(LDFLAGS) after $(BUILTINS_LDFLAGS) and $(LIBRARY_LDFLAGS) on
1795 the line that links bash
1798 - upgraded to version 2.185 from the texinfo-3.9 distribution
1801 - fixed a bug in tilde_expand so that enough space is allocated for
1802 the string and terminating null byte if a `~' does not appear.
1803 This was masked before by the bash malloc()
1809 - new test, BASH_TYPE_INT32_T, to check which builtin C type is
1811 - new test, BASH_TYPE_PTRDIFF_T, to check which builtin C type is
1812 appropriate for pointer arithmetic
1815 - check sizes of int and long, and for the existence of an int32_t
1816 basic system type. Call BASH_TYPE_INT32_T if int32_t is not
1817 defined anywhere in the system header files
1818 - check size of (char *), and for the existence of a ptrdiff_t
1819 basic system type. Call BASH_TYPE_PTRDIFF_T if ptrdiff_t is not
1820 defined anywhere in the system header files
1821 - added a check for <stddef.h>
1824 - add lines for SIZEOF_INT, SIZEOF_LONG, SIZEOF_CHAR_P, int32_t,
1825 u_int32_t, and ptrdiff_t
1826 - added line for HAVE_STDDEF_H
1829 - new version, with many changes and much better memory usage; old
1830 (bash-2.01) version is lib/malloc/omalloc.c
1832 lib/malloc/gmalloc.c
1833 - new version, with a number of changes and range checking included
1834 by default; old (bash-2.01) version is lib/malloc/ogmalloc.c
1837 - applied patch from 5/27 to make execute_simple_command fork early
1838 if it's part of a pipeline. This keeps assignment statements or
1839 other commands that don't require a builtin, function, or disk
1840 command to be executed from modifying the shell's environment
1843 - renamed from tests/execscript.sub? because those filenames are
1844 too long for System V 14-char filename systems
1847 - renamed from tests/source.sub? because those filenames are bad
1851 - renamed from tests/getopts.sub? because those filenames are bad
1854 tests/histexp.{tests,right}
1855 - renamed from histexpand.{tests,right} because those filenames are
1856 too long for System V 14-char filename systems
1859 - renamed from trap.sub1 because that filename was bad for DOS/Windows
1861 tests/ifs-[123].right
1862 - renamed from ifs.[123].right because those filenames were bad for
1865 tests/ifs-[123].test
1866 - renamed from ifs-test-[123].sh because those filenames were bad
1869 examples/startup-files/Bashrc.bfox
1870 - renamed from examples/startup-files/Bashrc because that filename
1871 conflicts with examples/startup-files/bashrc on case-insensitive
1875 - renamed from execscript.right because that filename is too long
1876 for System V 14-char filename systems
1879 - renamed from run-set-e-test
1882 - renamed from tests/misc/haertel.perftest because that filename is
1883 too long for System V 14-char filename systems
1886 - new version with full POSIX.2 BRE matching (character classes,
1887 collating symbols, equivalence classes), full support for
1888 strcoll(3), and case-insensitive pattern matching
1891 - new version, with necessary symbols for the new fnmatch.c
1893 tests/posixpat.{tests,right}, tests/run-posixpat
1894 - test suite for the POSIX.2 BRE pattern matching code
1897 - make sure that array assignment using the compound syntax empties
1898 the array before doing the assignment
1902 - new function, trap_to_sighandler(sig), which returns the correct
1903 trap handler for SIG depending on the information in sigmodes[sig]
1907 - extern declarations for trap_handler and trap_to_sighandler
1911 - if we get an interrupt while waiting for a command to complete,
1912 and there was a trap set on SIGINT that resets the handler to
1913 SIG_DFL, the value that waitchld uses for old_trap_handler will
1914 be wrong (it will be trap_handler, but trap_handler no longer
1915 knows anything about SIGINT). If old_signal_handler is trap_handler,
1916 but signal_is_trapped(SIGINT) returns 0, we need to call
1917 trap_to_sighandler to decide what to do
1923 - fix to set_locale_var to handle an assignment to LC_ALL (e.g., as
1924 the result of `unset LANG') when default_locale is null
1929 builtins/umask.def, doc/{bash.{1,html},bashref.texi}
1930 - added `-p' option for umask to print output in a reusable form
1934 doc/{bash.{1,html},bashref.texi}
1935 - removed descriptions of `-type', `-path', and `-all' options to
1936 the `type' builtin in preparation for removing them in the next
1940 - removed mention of `-type', `-path', and `-all' options from the
1941 long help description
1944 - new function: internal_warning, for warning messages
1947 - changed a call to internal_error to use internal_warning
1948 - modified change of 7/3 so that arrays are not emptied until
1949 just before the shell is about to assign the new values, so
1950 the old value can be used to generate the rhs of the assignment,
1951 if necessary. This is how `normal' shell variables work
1955 - delete_job now takes a second int argument and prints a warning
1956 message when deleting a stopped job if the second argument is
1959 jobs.c, builtins/jobs.def
1960 - changed all calls to delete_job to provide a proper second arg
1963 - broke rl_read_init_file into an `upper' and `lower' half in
1964 preparation for adding file inclusion capability to inputrc
1966 - handle_parser_directive now displays an error message if an
1967 unknown directive is encountered
1968 - parser_endif now prints an error message if an $endif without
1969 a matching $if is found
1970 - added `$include' parser directive to read bindings and commands
1971 from another file at that point
1973 lib/readline/doc/rluser.texinfo, doc/{bash.{1,html},readline.3}
1974 - documented new readline `$include' parser directive
1977 - added a new invocation option, --dump-po-strings, and code to
1978 make it dump translatable strings ($"...") in GNU gettext
1981 doc/{bash.{1,html},bashref.texi}
1982 - documented new `--dump-po-strings' invocation option
1984 lib/readline/{{kill,funmap}.c,readline.h}
1985 - added `rl_paste_from_clipboard()', bound to `paste-from-clipboard'
1989 - incorporated bfox's patches for `iterative' yank-last-arg handling.
1990 This means that one can keep pressing M-. and move backwards in
1991 the history, yanking the last argument of successive history lines
1993 lib/readline/rlwinsize.h
1994 - new file, encapsulates various locations of the definition for
1998 - augmented BASH_STRUCT_WINSIZE to look in termios.h as well as
1999 sys/ioctl.h for definition of `struct winsize'
2001 lib/readline/rltty.h
2002 - include "rlwinsize.h" after including tty-driver-specific header
2007 support/config.guess
2008 - add better support for SunOS on M68K (old Sun3 machines)
2011 - check for compound array assignment in read_token_word only if
2012 there are characters before the `=' (which would make it a legal
2013 assignment statement). This fixes the problem with defining a
2014 function named `=' with `=() { echo foo; }'
2018 - nohup_all_jobs and delete_all_jobs now take a parameter which
2019 says whether or not to restrict their operation to only running
2023 - changed all calls to delete_all_jobs
2026 - added `-a' (all jobs) and `-r' (running jobs only) options to
2029 doc/{bash.{1,html},bashref.texi}
2030 - documented new `-a' and `-r' options to `disown'
2032 findcmd.c, findcmd.h
2033 - new files with command searching code from execute_cmd.c and
2034 function declarations from execute_cmd.h
2036 Makefile.in, builtins/Makefile.in
2037 - updated dependencies to account for new findcmd.[ch]
2038 - updated dependencies to account for new redir.[ch]
2041 - new files with code that sets up lists and performs redirections
2042 from execute_cmd.c and execute_cmd.h
2045 - include new findcmd.h, redir.h
2049 Makefile.in, configure.in
2050 - PROFILE_FLAGS is now substituted into the Makefile by configure
2055 - make sure single_quote is called from xtrace_print_word_list
2056 to correctly quote each word of trace output, especially those
2057 with embedded quotes
2061 - extended BASH_CHECK_GETPW_FUNCS so that it checks that getpwuid
2062 and getpwnam can also be declared, as well as getpwent
2064 - in BASH_FUNC_PRINTF, cast printf to type `_bashfunc' before trying
2065 to assign it to `pf' to avoid any prototype problems in the
2070 - include <unistd.h> before any of the bash-specific header files,
2075 - include <errno.h> and declare `extern int errno' before including
2076 any of the bash-specific include files, but after <unistd.h>
2079 builtins/Makefile.in
2080 - PROFILE_FLAGS is now substituted into the Makefile by configure
2083 - new options, --enable-profiling and --enable-static-link, to turn
2084 on profiling with gprof and link bash statically (if using gcc)
2085 for use as a root shell. The former implies the latter. If
2086 we're linking statically, dynamic loading of new builtins is not
2090 - documented new --enable-profiling and --enable-static-link
2091 options in installation section; regenerated INSTALL
2094 - new global variable, glob_ignore_case, turns on case-insensitive
2095 filename matching in fnmatch() using the FNM_CASEFOLD flag
2097 doc/{bash.{1,html},bashref.texi}
2098 - documented new shopt `nocaseglob' option
2103 - when glob_complete_word is called with state == 0, make sure we
2104 set rl_filename_completion_desired so that proper quoting of
2105 the resultant filenames is performed
2111 - strcasecmp and strncasecmp replacements should have `const char *'
2112 as the first two arguments, to match OS definitions
2118 - changes for minix-2.0, mostly just adding #ifndef _MINIX around
2119 include files that minix doesn't provide, like <sys/param.h> and
2122 lib/readline/terminal.c
2123 - removed `outchar' function; use _rl_output_character_function in
2126 support/config.guess
2127 - changes to recognize HP_ARCH of `hppa2.0'
2130 - new `-N' option: `test -N file' returns true if FILE exists and
2131 has been modified since it was last accessed
2133 doc/{bash.{1,html},bashref.texi}
2134 - documented new `test -N' option
2139 - prefer /var/spool/mail to /usr/spool/mail in BASH_DEFAULT_MAIL_DIR
2142 lib/readline/{complete,bind}.c
2143 - new readline variable, print-completions-horizontally, which causes
2144 matches to be printed across the screen (like `ls -x') rather than
2145 up-and-down (like `ls')
2146 - new readline variable, completion-ignore-case, which causes filename
2147 completion and matching to be performed case-insensitively
2149 doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo
2150 - documented new print-completions-horizontally variable
2151 - documented new completion-ignore-case variable
2153 _distribution, Makefile.in
2154 - bumped the version number up to 2.02-alpha1
2157 - fixes so that the braces are not quoted by the filename quoting
2158 function when complete-into-braces is executed with M-{. The
2159 brace completion functions do filename quoting themselves
2163 - changed quote_string_for_globbing so that it takes a flags word
2164 as its second argument
2167 - defines for flags passed to quote_string_for_globbing
2169 subst.c,execute_cmd.c
2170 - changed calls to quote_string_for_globbing to pass the correct
2174 - added a `**' binary operator to do exponentiation (2**16 == 65536).
2175 precedence is lower than arithmetic operators, higher than unary
2176 operators (2**16-1 == 65535)
2178 doc/{bash.{1,html},bashref.texi}
2179 - documented new `**' arithmetic binary operator
2184 - added new (currently undocumented) `--wordexp' option to do the
2185 job required by POSIX.2 wordexp(). If -n is supplied along with
2186 --wordexp, command substitution is disallowed and the shell
2187 exits with a status of 125 if one is attempted. If there is an
2188 expansion error, the shell exits with a status of 127. If there
2189 is a shell parsing error, the shell exits with a status of 126.
2190 Otherwise, the exit status is 0. The current output is
2194 expanded words, one per line, separated by newlines
2196 This will have to be changed when an interface to glibc is coded
2201 - reduced the default size of the filename hash table from 631
2205 - don't call initialize_siglist if HAVE_UNDER_SYS_SIGLIST is defined
2209 - don't compile this file if HAVE_UNDER_SYS_SIGLIST is defined
2213 - fix to make $RANDOM work better in subshells
2217 - new macro, BASH_DECL_UNDER_SYS_SIGLIST, looks for _sys_siglist in
2218 <signal.h> and <unistd.h>, defines UNDER_SYS_SIGLIST_DECLARED if
2221 - change BASH_UNDER_SYS_SIGLIST to require BASH_DECL_UNDER_SYS_SIGLIST,
2222 like BASH_SYS_SIGLIST requires AC_DECL_SYS_SIGLIST
2226 - add a line for UNDER_SYS_SIGLIST_DECLARED
2230 - make sure that SVR4_2 is defined for machines that have $host_os
2231 sysv4.2* (e.g., sysv4.2MP) as well as $host == sysv4.2
2237 - new command type, ARITH_COM, used to create and execute a ((...))
2238 command without translating it into let "..."
2241 - changes to the grammar and lexer so that ((...)) is parsed as a
2242 command of type ARITH_CMD. An ARITH_CMD is a WORD_LIST, for
2243 future expansion, even though only the first word is used
2245 make_cmd.c, make_cmd.h
2246 - definition and declaration of a function to build an arithmetic
2250 - added code to dispose of arithmetic commands
2253 - added code to print arithmetic commands, both `regularly' and
2254 when they're being traced with `set -x'
2257 - extern declaration for xtrace_print_arith_cmd
2260 - added code to copy arithmetic commands
2263 - added code to directly execute arithmetic commands -- they are
2264 a shell_control_structure, so just about everything like
2265 redirections and piping is taken care of by the boilerplate code.
2266 All that's needed is to expand the expression (which is within
2267 double quotes -- added by parse.y:parse_arith_cmd()), print it
2268 if tracing is enabled, call the expression evaluator, and return
2269 an appropriate result
2274 - new function, set_buffered_stream(fd, bp), sets the buffered stream
2275 associated with FD to BP and returns the old buffered stream
2278 - extern declaration for set_buffered_stream
2281 - call set_buffered_stream rather than manipulating the BUFFERS array
2285 - unset_bash_input now takes an argument, CHECK_ZERO. This tells it
2286 whether to check whether default_buffered_input is >= 0 or just > 0
2289 - changed extern declaration for unset_bash_input
2291 execute_cmd.c, jobs.c, nojobs.c
2292 - changed calls to unset_bash_input to add appropriate argument
2295 - #undef B_* before defining them as flag values for b_flags. Some
2296 systems, like SVR4, have a B_ERROR define in a file included by
2297 jobs.c and nojobs.c, and it causes a warning
2302 - rewrote most of fnmatch(), so that it now implements ksh-88 style
2303 pattern matching (`[@+*?!](patlist)') if the FNM_EXTMATCH flag
2307 - added a define for FNM_EXTMATCH
2311 lib/readline/display.c
2312 - fixed _rl_redisplay_after_sigwinch () so that it really redisplays
2313 only the portion after the final newline of a multi-line prompt
2317 - attempt_shell_completion no longer returns matches if a glob pattern
2318 matches more than one filename -- it caused too many problems
2324 - updated glob_pattern_p so that the extended matching operators
2328 - udpated unquoted_glob_pattern_p so that the extended matching
2329 operators are recognized
2330 - udpated quote_globbing_chars so that the extended matching
2331 operators are recognized and quoted appropriately
2334 - updated match_pattern_char so that the extended matching operators
2338 - updated read_token_word so that it parses an extended matching
2339 pattern as a single word
2342 - if a job is suspended with SIGTSTP, and the user has set
2343 checkwinsize with `shopt', update the window size
2346 pathexp.c, pathexp.h
2347 - new global variable, extended_glob, controls whether the extended
2348 pattern matching features are enabled
2351 - new define, FNMATCH_EXTFLAG, to be OR'd with other values for
2352 flags argument to fnmatch to enable the extended pattern matching
2353 features if extended_glob is set
2355 {pathexp,execute_cmd,bashhist,subst,test}.c, builtins/help.def
2356 - changed calls to fnmatch to add FNMATCH_EXTFLAG to the flags arg if
2357 extended_glob is non-zero
2360 - changed flags arg passed to fnmatch to include FNM_EXTMATCH if
2361 extended_glob is non-zero (#ifdef SHELL)
2366 - added a new `extglob' shell option, controls the value of
2371 doc/{bash.{1,html},bashref.texi}
2372 - documented new extended pattern matching operators and the `extglob'
2375 tests/{extglob.{tests,right},run-extglob}
2376 - test suite for the new extended globbing features
2380 parse.y, pathexp.h, lib/glob/fnmatch.c
2381 - made the extended globbing code #ifdef EXTENDED_GLOB
2384 - added a line for EXTENDED_GLOB, controlled by configure
2387 - new option, --enable-extended-glob, controls defining of
2388 EXTENDED_GLOB (on by default)
2391 - documented new `configure' `--enable-extended-glob' option
2396 - new `printf' builtin, implemented according to POSIX.2 spec
2399 Makefile.in,builtins/Makefile.in
2400 - added necessary stuff for new printf builtin
2404 lib/readline/isearch.c
2405 - change to make ^G interrupt the incremental search correctly
2408 configure.in, config.h.in
2409 - configure now checks for the availability of strtoul(3)
2412 - use strtoul for the `%o', `%u', `%x', and `%X' formats if it
2417 tests/{printf.{right,tests},run-printf}
2418 - extensive test suite for the new `printf' builtin
2420 builtins/Makefile.in
2421 - change so that `builtext.h' is not recreated every time the source
2422 file for a builtin is changed if the contents are the same. This
2423 keeps many files from being recompiled
2428 - changed verify_substring_values so that it returns -1 for substring
2429 range errors, 0 for expression errors, and 1 for success
2431 - changed parameter_brace_substring to return an error if
2432 verify_substring_values returns 0, and a null string if it returns
2433 -1. This matches the ksh93 behavior
2437 - changed decode_signal so that it makes sure the first three
2438 characters of a signal name are `SIG' before allowing the `SIG'
2439 prefix to be omitted. This is so a signal spec of `T' does not
2440 match `EXIT', for instance
2444 - make sure that showtrap() displays traps for signals with unknown
2445 names using the signal number
2448 - make sure that `bash -r' doesn't turn on the restricted mode until
2449 after the startup files are executed
2452 doc/{bash.{1,html},bashref.texi}
2453 - documented printf builtin
2458 - added \xNNN escape to ansicstr -- NNN are up to three hex digits.
2459 This affects $'...', `echo -e', and printf
2462 - added \xNNN escape to bexpand -- NNN are up to three hex digits.
2463 This affects printf's `%b' conversion specifier
2465 doc/{bash.{1,html},bashref.texi}
2466 - documented new \xNNN escape sequence for echo, $'...', and printf
2468 builtins/setattr.def
2469 - make sure that a variable found in the temp environment does not
2470 cause a null string to be assigned by bind_variable (e.g.,
2478 - fixed a bug that sometimes caused bad memory (pointer into an
2479 allocated block) to be passed to free when doing arithmetic
2480 substitution. Bug report from stevet@myofb.org
2486 - considerable changes: moved the code that expands a single
2487 $... parameter expansion into a separate function: param_expand()
2488 This function returns a string, which may contain characters
2489 quoted with CTLESC or CTLNUL without doing word splitting
2490 - changed expand_word_internal to not remove the expansion of "$*"
2491 if the number of positional parameters is > 0
2492 - changed the '"' case of expand_word_internal to remove quoted
2493 nulls from the resultant word if the expansion was not "$@", and
2494 the word is not a quoted null string ([] == CTLNUL, [1] == '\0')
2496 subst.c, variables.c
2497 - moved the code that handles special variables from subst.c to
2503 - rearranged the source a bit to group functions with similar
2505 - fixed parameter_brace_expand so that it no longer allows
2506 indirect expansion of `special' variables
2507 - fixed parameter_brace_expand so taking the length of some of
2508 the shell's special parameters works again
2509 - moved all of the code that computes the length of a shell
2510 parameter (the ${#xxx} expansion) into parameter_brace_expand_length.
2511 Previously, the code that handled the lengths of the shell's
2512 special parameters was in parameter_brace_expand_word
2513 - valid indirect expansions are now only variable names or positional
2519 - fixed param_expand to raise an expansion error if $! is being
2520 expanded and no asynchronous processes have been created
2521 - an expression error in a $((...)) arithmetic expansion now causes
2522 a non-interactive shell running in POSIX mode to exit
2523 - relaxed change of 8/20 to allow indirect references to $#, $@, $*
2525 builtins/bashref.texi
2526 - documented new posix-mode exit on invalid expressions in $((...))
2528 lib/readline/complete.c
2529 - don't call rl_strpbrk unless rl_filename_quote_characters is not
2530 NULL -- strpbrk requires non-NULL arguments
2536 - don't make `history-expand-line' a bindable command unless
2537 BANG_HISTORY is defined, and don't compile the code for that
2538 command in unless BANG_HISTORY is defined
2539 - make history_expand_line(), tcsh_magic_space(), alias_expand_line(),
2540 and history_and_alias_expand_line() int-returning functions that
2541 return 0 for success and non-zero on error. This allows
2542 tcsh_magic_space() to just call history_expand_line() and insert
2543 a space if that returns successfully
2544 - `magic-space' is now a bindable readline command
2546 doc/bash.{1,html}, lib/readline/doc/rluser.texinfo
2547 - documented new `magic-space' bindable readline command
2552 - fixed decode_prompt_string so that values of $PWD longer than
2553 PATH_MAX don't cause buffer overruns (char t_string[PATH_MAX])
2557 - fixed polite_directory_format so that values of $HOME longer
2558 than PATH_MAX don't cause buffer overruns (char tdir[PATH_MAX])
2562 - fix to expansion of $* so that the positional parameters are
2563 separated by the first character of $IFS, even when the expansion
2564 is not within double quotes, so the correct split is still
2565 performed even when IFS does not contain a space. Works for
2567 - fix to expansion of $@ so that the positional parameters are
2568 separated by the first character of $IFS, even when the expansion
2569 is not within double quotes, so the correct split is still
2570 performed even when IFS does not contain a space. Works for
2572 - new function, string_list_dollar_at(), which is to $@ as
2573 string_list_dollar_star is to $*
2574 - fixed expansion of $@ so that splitting is still done even if
2575 IFS is unset or NULL, as POSIX.2 specifies (section 3.5.2)
2576 - fixed expansion of $* so that it expands to multiple words if there
2577 is more than one positional parameter, just like $@, even if
2578 IFS is unset or NULL
2579 - new function list_quote_escapes, quotes (with CTLESC) all
2580 CTLESC and CTLNUL characters in each member of the list
2582 tests/dollar-{at,star}.sh
2583 - combined into dollar-at-star, changed run-dollars accordingly
2588 - make the `tests' target use $(SHELL) instead of hardcoding `sh'
2593 - expand_word_list_internal now takes a flags word as the second
2594 argument, telling which expansions to perform on the WORD_LIST
2595 - broke expand_word_list_internal into several functions: one
2596 each to do brace expansion, glob expansion, and the `normal'
2598 - new extern function: expand_words_shellexp() to perform the
2599 `normal' shell expansions on a WORD_LIST
2602 - extern declaration for expand_words_shellexp
2605 - fixed a problem with attempt_shell_completion where it attempted
2606 to refer to rl_line_buffer[-1] (completion at the start of the
2607 line, which means that ti == -1, which means that the test for
2608 rl_line_buffer[ti] at line 715 was an array bounds error
2612 - new function, parse_string_to_word_list(), which takes a string
2613 and runs it through the parser, returning the resultant word
2617 - new extern declaration for parse_string_to_word_list()
2620 - change assign_array_var_from_string to first split the string
2621 between the parens on whitespace, then expand the resultant
2622 list of words with all the shell expansions before doing the
2628 - redirection_error is no longer a static function
2630 builtins/evalstring.c
2631 - changes to handle $( < filename ) (equivalent to $(cat filename))
2635 - added two new functions: rl_unbind_function_in_map(func, map),
2636 which unbinds all keys that execute FUNC in MAP; and
2637 rl_unbind_command_in_map(command, map), which unbinds all keys
2638 bound to COMMAND in MAP
2640 lib/readline/readline.h
2641 - extern declarations for rl_unbind_{function,command}_in_map
2643 lib/readline/doc/rltech.texi
2644 - documented rl_unbind_{function,command}_in_map
2647 - added a new option, -u FUNCNAME, which unbinds all key sequences
2648 bound to FUNCNAME in the specified (or current) keymap
2650 doc/{bash.{1,html},bashref.texi}
2651 - documented new $( < filename ) command substitution
2652 - documented new bind -u FUNCNAME option
2657 - send SIGHUP to all jobs when an interactive login shell exits if
2658 the variable `hup_on_exit' is non-zero
2659 - modified run_startup_files so that if `NON_INTERACTIVE_LOGIN_SHELLS'
2660 is #define'd (perhaps in config.h.top, though there is nothing there
2661 for it), all login shells (interactive and non-interactive) run
2662 /etc/profile and one of the per-user login shell startup files
2665 - new shopt option `huponexit' to control the value of hup_on_exit
2667 doc/{bash.{1,html},bashref.texi}
2668 - documented new `huponexit' shell option
2673 - changed contains_shell_metas to return 1 if a tilde appears at the
2674 start of a string or after a `=' or `:'
2675 - changed backslash_quote to quote a tilde if it appears at the start
2676 of a string or after a `=' or `:'
2678 lib/readline/complete.c
2679 - moved rl_tilde_expand to util.c; it doesn't really have anything
2680 to do with completion
2681 - moved insert_text to readline.c, renamed it _rl_replace_text (since
2682 that's really what it does), changed callers
2683 - moved code that postprocesses the list of completion matches into
2684 a new function: postprocess_matches
2685 - new implementation of tcsh-like menu completion in a single new
2686 function: rl_menu_complete
2688 lib/readline/{funmap.c,readline.h}
2689 - necessary declarations for binding rl_menu_complete to the
2690 new `menu-complete' command
2692 doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo
2693 - documented new `menu-complete' bindable readline command
2698 - delete_job should print a warning only if subshell_environment
2699 is 0, so we don't print bogus warnings when shell scripts without
2700 a leading #! are executed
2705 - fixed the code so that the `read' is automatically restarted when
2706 it returns -1 with errno == EINTR. SIGINT is handled by the
2707 interrupt handler, since interrupt_immediately is set to 1, so
2708 this handles things like SIGCHLD
2714 - reorganized the code slightly to make it easier to add the ksh-like
2715 [[...]] compound command
2718 - new file, with extern declarations for functions available in test.c
2721 - moved declaration of test_command to test.h
2728 {command,make_cmd,dispose_cmd,externs,subst}.h
2730 {make,dispose,copy,print,execute}_cmd.c
2731 - changes to add the new ksh-93 compatible [[...]] conditional command
2734 - new enable option, --enable-cond-command, to compile in the [[...]]
2738 - new #define, COND_COMMAND, to compile in the [[...]] command code
2740 tests/{run-cond,cond.{tests,right}}
2741 - test suite for the new [[...]] command
2743 {builtins,lib/{readline,glob,tilde}}/Makefile.in
2744 - explicit dependencies for .o files on .c files for losing makes
2747 doc/{bash.{1,html},bashref.texi}
2748 - documented the new `[[' compound command
2749 - documented the test/[ builtin behavior based on the number of
2750 arguments in the description of the builtin
2751 - made a new section for conditional expressions that just lists
2752 the available primaries -- the connectives and other operators
2753 are listed in the description of the [[ command and the test/[
2759 - minus_o_option_commands is now a global function so the shopt
2761 - minus_o_option_commands now takes an argument telling it which
2762 options to print, just like list_minus_o_options
2763 - new function, print_minus_o_option, which prints the value of
2764 a `set -o' option either in the traditional format or in the
2765 format used by `set +o'
2766 - changed list_minus_o_opts and minus_o_option_commands to call
2767 print_minus_o_option
2770 - `shopt -p' now causes output to be printed in a format reusable
2771 as input (the format is a series of shopt commands, like the
2773 - fixed a bug that made `shopt -so' and `shopt -uo' not work
2774 - fixed list_shopt_o_options so that `shopt -op' acts like `set +o'
2775 - fixed list_shopt_o_options to that `shopt -op optname' prints the
2776 value of optname in a reusable format
2777 - fixed list_some_o_options so that `shopt -ops' and `shopt -opu'
2778 work and display output in a reusable format
2782 doc/{bash.{1,html},bashref.texi}
2783 - documented new `shopt -p' behavior
2786 - made `bash +o' display the same output as `set +o' and then
2787 start an interactive shell (previously `bash -o' and `bash +o'
2788 displayed the same thing)
2791 - added prototypes to the extern function declarations
2795 builtins/evalstring.c
2796 - fixed the DISCARD case of the jump_to_top_level so that it
2797 doesn't try to call dispose_command(command) after the
2798 `pe_dispose' unwind frame gets run, since that disposes the
2804 - test_eaccess is now a global function so that globbing code can
2808 - rewrote glob_vector to be slightly more efficient and to not
2809 read the directory if the filename pattern does not contain
2810 any globbing chars. This satisfies the POSIX requirement that
2811 read permission is not required for a directory when the
2812 pathname component does not contain a pattern character (bug
2813 reported by jsm28@cam.ac.uk)
2816 - fixed parameter_brace_expand so that ${array[@]} and ${array[*]}
2817 behave correctly when IFS is unset or set to something that does
2818 not contain a space (they should result in separate words, just
2821 tests/{run-array2,array-at-star,array2.right}
2822 - tests for the expansions of ${array[@]} and ${array[*]}, derived
2823 from the tests in dollar-at-star
2828 - fixed cleanup_dead_jobs so that it doesn't remove the job
2829 containing last_asynchronous_pid from the job table. This
2830 fixes the POSIX.2 `wait' requirement problem
2835 - added `\r' escape sequence to the prompt expansion code
2837 lib/readline/chardefs.h
2838 - added defines for ISOCTAL, OCTVALUE, isxdigit (if not defined),
2842 - added `normal' echo/printf-like backslash escapes to the
2843 key sequence translation code, with the addition that \d
2844 expands to RUBOUT. This means that key sequence definitions
2845 (before the `:') and macro values may contain these special
2846 backslash-escape sequences
2847 - now that we can translate octal escape sequences in key bindings,
2848 change _rl_get_keyname so that it turns characters with values
2849 128-159 inclusive into octal escape sequences (\200-\237), since
2850 those characters are not ASCII or ISO Latin 1
2852 doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo
2853 - documented new backslash escapes for readline key sequence and
2857 - new function, get_dirstack_from_string(char *string), returns an
2858 element from the directory stack or null, treating the argument
2859 exactly as `dirs string' would, with the exception that if
2860 the first character of `string' is not `+' or `-', a `+' is
2864 - new extern declaration for get_dirstack_from_string
2867 - added code to bash_special_tilde_expansions to get the expansion
2868 using get_dirstack_from_string() if the first character of the
2869 tilde-prefix is a digit or the first character is a `+' or `-'
2870 and the second is a digit
2872 tests/dstack.{tests,right}
2873 - renamed from dirstack.{tests,right}
2875 tests/dtack2.{tests,right}
2876 - new tests for the directory stack tilde expansion code
2879 - now runs both dstack and dstack2
2884 - reordered header file inclusion for irix 4
2887 - fixed select_query so that a reply that is not a number is treated
2888 the same as a numeric reply that is out of range
2891 - added a backwards-compatibility definition of _rl_savestring()
2894 - initialize_shell_options now takes an argument saying whether or
2895 not we should parse $SHELLOPTS from the environment. The shell
2896 does not parse the value if it's restricted, running setuid, or
2897 running in `privileged mode'
2900 - change call to initialize_shell_options to add the correct argument
2903 - changed extern declaration for initialize_shell_options
2905 doc/{bash.{1,html},bashref.texi}
2906 - added note that the shell ignores $SHELLOPTS in the environment at
2907 startup if running in privileged mode
2908 - added note that the restricted shell does not parse $SHELLOPTS from
2909 the environment at startup
2914 - change BASH_RLIMIT_TYPE so that it looks for rlim_t in
2915 <sys/resource.h> as well as <sys/types.h>, for Solaris 2.6
2916 - new macro, BASH_LARGE_FILE_SUPPORT, to enable special compilation
2917 options for large files on Solaris 2.6 (from eggert@twinsun.com)
2920 - the `file_size' member of the FILEINFO struct should be of
2922 - the `size' variable in file_has_grown should be of type `off_t'
2923 - the RESET_MAIL_FILE macro should initialize file_size to 0, not 0L
2925 builtins/Makefile.in
2926 - LDFLAGS and LOCAL_LDFLAGS are now set by configure
2927 - `mkbuiltins' is now created from `mkbuiltins.o' instead of directly
2928 from the source to the executable
2931 - fixed _evalfile so that it handles large files correctly on
2932 systems where the st_size member of `struct stat' will not fit
2935 builtins/mkbuiltins.c
2936 - don't assume that st_size fits into an int
2939 - the `b_size' member of a struct BSTREAM is now of type `size_t'
2940 - changed third argument to make_buffered_stream to size_t; changed
2942 - changed `size' variable in fd_to_buffered_stream to type `size_t'
2945 - include <sys/resource.h> if HAVE_SYS_RESOURCE_H and RLIMTYPE are
2946 both defined, for possible necessary definition of RLIMTYPE
2947 (e.g., on Solaris 2.6)
2949 {execute_cmd,jobs}.c, builtins/times.def
2950 - don't include <sys/resource.h> explicitly if RLIMTYPE is defined,
2951 since general.h will include it in that case
2954 - new function, char *_rl_read_file(filename, sizep), which reads
2955 FILENAME into a malloced buffer, returning the buffer and the
2956 size of the buffer in *SIZEP
2958 lib/readline/histfile.c
2959 - changed read_history_range and history_truncate_file to handle
2963 - find_hashed_filename should not add `./' to the front of a pathname
2964 that already begins with `./'
2969 - recognize `hppa2.0' as a valid machine architecture
2972 - changed BASH_CHECK_LIB_TERMCAP so that `gnutermcap' is not chosen
2973 if `$prefer_curses' is set to something
2976 - don't use HISTCONTROL or HISTIGNORE to remove lines from the
2977 second and subsequent lines of a multi-line command
2978 (current_command_line_count > 1). Old code did this only when
2979 command-oriented-history was enabled
2981 doc/{bash.{1,html},bashref.texi}
2982 - changed descriptions of HISTCONTROL and HISTIGNORE to state that
2983 these variables are not applied to the second and subsequent
2984 lines of a multi-line command
2986 builtins/hash.def, {copy,dispose}_cmd.c
2987 - include "bashtypes.h" -- cray machines need it because of their
2988 oddball definition of `word'
2991 - changed check of ${host_cpu} to check for `*cray*' and `*Cray*'
2992 when deciding whether to include the GNU malloc, since it
2993 seems that ${host_cpu} gets set to `CrayYMP'
2998 - look for strtod and strtol in libc
2999 - make lib/sh directory in build directory if not there
3000 - create lib/sh/Makefile
3003 - added HAVE_STRTOD and HAVE_STRTOL
3006 - changes for lib/sh/libsh.a (shell library)
3009 - took out the `#ifdef STRTOUL' code, since strtoul is in libsh.a,
3010 and will be resolved from there if it's not in libc
3013 - call strtol() instead of string_to_long()
3015 general.c, general.h
3016 - removed string_to_long
3017 - changed legal_number to use strtol so it correctly sets errno
3018 to ERANGE on overflow
3019 - moved bash_getcwd_errstr here from lib/sh/oslib.c
3022 - moved extern declarations for functions defined in libsh to a
3023 separate section of the file, added extern declarations for
3024 other functions in libsh
3027 - changed macro definition for string_to_rlimtype to call strtol
3028 directly instead of string_to_long
3031 - moved get_clock_tck to its own file, since it's compiled in
3037 - moved getenv() and __getenv() here from lib/sh/oslib.c
3039 lib/sh/{setlinebuf,strerror,strcasecmp}.c
3040 - moved {setlinebuf,strerror,strcasecmp}() from oslib.c to
3043 lib/sh/Makefile.in, Makefile.in
3044 - changes for new files in lib/sh
3047 - new macro BASH_SYS_RESTARTABLE_SYSCALLS, which does what
3048 AC_SYS_RESTARTABLE_SYSCALLS does, but using posix sigaction()
3051 - call BASH_SYS_RESTARTABLE_SYSCALLS if ac_cv_sys_restartable_syscalls
3057 - catch out-of-range jobs better in disown_builtin
3060 - don't build with GNU malloc on cygwin32
3063 - change signal_name to handle the case where signal_names[sig] is
3064 NULL, which can happen on cygwin32
3067 - changes to do_piping to make pipes text mode (O_TEXT) on cygwin32
3070 - new directory with cache files and other stuff for cross-compiling
3071 bash (currently only for building for cygwin32 on a Unix machine)
3073 cross-build/cygwin32.cache
3074 - new file containing configuration variable assignments for
3075 cygwin32 that would otherwise require a default case for AC_TRY_RUN
3078 - source ${srcdir}/cross-build/cygwin32.cache on CYGWIN32 systems
3079 if we're cross-compiling on a unix machine
3080 - set $CC_FOR_BUILD for cygwin32 cross-compiling environment
3083 - CC_FOR_BUILD is now a variable set by configure
3085 builtins/mkbuiltins.c
3086 - only check for read(2) returning <= 0 in extract_info() (error
3087 and exit on < 0, warning and return on == 0)
3090 - only check for read(2) returning <= 0 in _evalfile() (error and
3091 and failure return on < 0, success on == 0 while short-circuting
3098 - moved to lib/sh/vprint.c
3101 - added entries for vprint.[co] in the appropriate places
3103 cross-build/win32sig.h
3104 - a version of signames.h for cross-compiling for the CYGWIN32
3105 environment on a Unix machine (from noer@cygnus.com)
3108 - made all cases of AC_TRY_RUN and AC_TRY_COMPILE have reasonable
3109 default cases for cross-compiling, and tell the user what they are
3112 - removed vprint.c from shell sources and vprint.o from shell
3114 - added a level of indirection for signames.h -- the variable
3115 SIGNAMES_H is set by configure to either `lsignames.h' or
3116 a file for a cross-compilation environment (currently only
3117 the cygwin32 stuff is supported). Then that file is copied
3118 to `signames.h'. `lsignames.h' is created by `mksignames' as
3119 was previously used to create signames.h directly
3122 - set SIGNAMES_H to either `$(srcdir)/cross-build/win32sig.h' or
3123 `lsignames.h' as appropriate, substitute into Makefile
3127 builtins/Makefile.in
3128 - CC_FOR_BUILD is now set by configure and used to build mkbuiltins
3132 - new variable attribute `att_tempvar', set if the SHELL_VAR * was
3133 constructed on the fly from the temporary environment
3136 - find_name_in_env_array now sets the `att_tempvar' attribute on
3137 the SHELL_VAR it creates
3140 - search_for_command now disposes the SHELL_VAR created by searching
3141 the temporary environment for $PATH, if it is found there
3142 - _find_user_command_internal also disposes of the SHELL_VAR if it
3143 has the `att_tempvar' attribute set
3146 - show_name_attributes looks in the temporary environemnt, so it needs
3147 to dispose the SHELL_VAR if it has the att_tempvar attribute set
3150 - parameter_brace_expand_word now disposes of the SHELL_VAR returned
3151 by find_variable if it has the att_tempvar attribute set
3152 - ditto for param_expand and word_split
3155 - disallow null pid arguments instead of treating them as 0
3156 - display a usage message and return failure if no pid or job
3157 arguments are supplied
3161 builtins/declare.def
3162 - make `var=value declare -x var' behave the same as
3163 `var=value export var' and `var=value declare -r var' behave the
3164 same as `var=value readonly var', now that we have the `tempvar'
3170 - non-interactive shells shouldn't report jobs killed by a SIGINT,
3171 even if the standard output is to a terminal
3172 - pretty_print_job should add a CR at the end of its output if the
3173 shell is interactive and asynchronous notification is being
3174 performed. This fixes the problem with extra CRs in the output
3178 - changed canonicalize_pathname to change `//' into `/', but leave
3179 other pathnames starting with two consecutive slashes alone
3184 lib/readline/histexpand.c
3185 - fixed history_expand so that the appearance of the history
3186 comment character at the beginning of a word inhibits history
3187 expansion for the rest of the line
3192 - moved set_pipestatus_array to variables.c
3195 - new function, set_pipestatus_from_exit(int), which sets the
3196 PIPESTATUS variable from a command's exit status
3199 - extern declarations for set_pipestatus_from_exit and
3200 set_pipestatus_array
3203 - fixed execute_simple_command to call set_pipestatus_from_exit
3204 if a foreground builtin or function, or a foreground null
3210 - fixed run_startup_files to detect being run by sshd, and treat
3211 that case as equivalent to being run by rshd
3216 - make sure `set -a' doesn't cause SHELLOPTS to be exported when
3217 a change is made to one of the shell options
3222 - fix to shell_glob_filename in the code that uses a POSIX glob
3228 - fix cleanup_dead_jobs to hang onto the job corresponding to
3229 last_asynchronous_pid only if the shell is not interactive
3230 (this still has the problem that until a new async process
3231 is started, the job will stay in the jobs table)
3233 configure.in,aclocal.m4
3234 - added a new macro, BASH_TYPE_U_INT32_T, to check for u_int32_t
3235 separately from int32_t, since there are systems (HP-UX 10.20)
3236 that have a define for the latter but not the former
3241 - cleanup_dead_jobs no longer checks whether the job it is deleting
3242 corresponds to last_asynchronous_pid
3243 - notify_of_job_status and mark_dead_jobs_as_notified now will not
3244 mark the job corresponding to last_asynchronous_pid as notified
3245 if the shell is not interactive
3246 - wait_for_single_pid, if told to wait for last_asynchronous_pid,
3247 or the job of which it is a member, will take care of marking
3248 the job as notified after calling wait_for and collecting the
3249 status. This means that two successive `wait' calls for $! will
3250 succeed the first time and fail the second, as POSIX.2 specifies
3251 (take this code out if it causes problems)
3256 - wait_for_job, if told to wait for the job corresponding to the
3257 last async pid, will mark the job as notified after waiting for
3258 it and collecting the status
3261 - fixed MEMBER macro to avoid reading past end of S (it used to
3262 test s[1] before s[0], which is an error if s == "")
3265 - expand_word_internal should free ISTRING before returning if
3266 param_expand returns an error
3267 - parameter_brace_expand_word should free the memory it allocates
3268 and passes to param_expand
3271 - execute_arith_command should call dispose_words on the list
3272 returned by expand_words
3275 - after calling parse_arith_command, read_token needs to free the
3276 string value that parse_arith_command fills in, since make_word
3277 makes a copy of the string it's passed
3282 - cond_expand_word needs to free the value returned by string_list
3283 after it is run through quote_string_for_globbing
3286 - make sure cond_term frees yylval.word if it is just a `!' and
3287 it's parsed as a term negation operator
3290 - assign_array_var_from_string needs to free the word list returned
3291 by parse_string_to_word_list after calling expand_words_shellexp
3295 - changed execute_simple_command to avoid saving the_printed_command
3296 into command_line until just before it's needed. This should save
3297 time and prevent memory leaks on errors, but it must be watched
3298 closely to make sure that the_printed_command doesn't change out
3299 from under execute_simple_command before we copy it
3304 - alias and unalias should print error messages when passed an
3305 argument that is not an alias for printing or deletion,
3306 respectively, even if the shell is not interactive
3309 - `logout' will no longer exit a non-login non-interactive shell
3314 - add `koi8-r' as a legal LANG value
3317 - if `alias' or `alias -p' is executed when no aliases are defined,
3318 the return status should be 0, according to POSIX.2
3323 - changed a couple of calls to make_word_list (make_word(z), ...)
3324 to add_string_to_list (z, ...)
3327 - execute_cond_command now sets this_command_name to `[['
3332 - all_visible_{function,variable}s and the functions they call
3333 should be compiled in only if READLINE is defined
3338 - remove some leading whitespace before preprocessor statements in
3339 BASH_KERNEL_RLIMIT_CHECK
3342 - fix declarations for group_member so the extern declaration in
3343 general.h agrees with the definition in general.c (fix from
3344 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>)
3347 - print the new working directory if the shell is interactive
3349 - don't print the new working directory if it's found in $CDPATH
3350 if the shell is not interactive
3355 - fixes to bindpwd so that it copes with get_working_directory
3356 returning NULL (bug from schwab@issan.informatik.uni-dortmund.de)
3360 support/config.guess
3361 - add support for new OS name for SINIX SVR4 systems
3367 - `unset' should check that a function it's trying to unset is a
3368 legal identifier only when in POSIX mode
3371 - changed here_document_to_fd to try and make sure the filename
3372 used for the here document is `more unique', since the old
3373 version would fail if two here documents were created in less
3379 - POSIX.2 says that if CDPATH is used to find the new directory,
3380 and it's not relative to the current directory, the new directory
3381 name should be displayed on stdout even if the shell is not
3387 - changes so that `time' is recognized as a reserved word only at
3388 the beginning of a pipeline (the last read token is one of 0,
3389 `;', `\n', `&&', `||', or `&'):
3391 o add clause to special_case_tokens that does the check
3392 and returns TIME if the conditions are met
3393 o take check for `TIME' out of CHECK_FOR_RESERVED_WORD, but
3394 leave it in the word_token_alist so that `type' still
3395 reports it as a `keyword'
3396 o new function, time_command_acceptable(), encapsulates the
3397 necessary conditions for `time' to be returned as a
3400 [bash-2.02-alpha1 frozen]
3405 - fix define for isgraph so that it does not return success for space
3406 - fix strcompare() so that the call to strcoll is surrounded by
3412 - the `test' argument to brackmatch() should be of type `unsigned char'
3417 - make sure execute_arith_command sets this_command_name to `(('
3422 - make sure the code for pushing and popping strings is compiled in
3423 if either ALIAS or DPAREN_ARITHMETIC is defined, because the ((
3424 code uses push_string in the case of a nested subshell
3425 - fix cond_skip_newlines so it resets the prompt to $PS2 while
3426 parsing an unfinished conditional command
3428 dispose_cmd.c, copy_cmd.c, builtins/hash.def
3429 - fixes to not use `word' as a variable name or the name of a
3430 function parameter to get around stuff in the Cray Unix include
3434 - return failure immediately if an illegal format character is
3438 - make the code that creates here-documents behave better if the
3439 file it's trying to create already exists for some reason
3441 lib/readline/complete.c
3442 - changed print_filename to return the number of characters it
3443 outputs; changed callers to use that value. This makes columns
3444 line up when printing completion listings with filenames
3445 containing control characters
3448 - fixed a typo in the quote removal section
3453 - free_string_list() needs to check that t->expander is not NULL
3454 before trying to dereference it
3455 - reset_parser() doesn't need to set pushed_string_list to NULL
3456 after calling free_string_list(), since free_string_list does it
3458 configure.in,cross-build/cygwin32.cache
3459 - fixes from Geoff Noer for better cygwin32 cross-compilation
3461 tests/printf.{tests,right}
3462 - removed test for integer overflow, since error messages differ
3466 - fixed a problem with unquoted_glob_pattern_p that made things
3467 like `x+*' not expand correctly
3470 - fixed a problem with glob_pattern_p that made things like `x+*'
3471 not expand correctly
3474 - if `cd -P' is executed, or `set -o physical' has been executed,
3475 the value of $PWD after a successful cd will not contain any
3476 symlinks, regardless of whether or not the shell is in posix mode
3480 lib/readline/shell.c
3481 - include <string.h> or <strings.h> as appropriate
3486 - take out the code in backslash_quote() that looks for tildes to
3487 quote, for the time being
3488 - if getcwd() fails, get_working_directory now prints the error
3489 message corresponding to errno in addition to the rest of the
3490 information -- TENTATIVE CHANGE
3493 - fix from Paul Smith to make getcwd() behave better in the presence
3494 of lstat(2) failures
3497 - when copying the replacement string into the output string being
3498 constructed, strsub() needs to make sure enough space for the
3499 replacement string is allocated, not the length of the pattern
3500 (use REPLEN, not PATLEN)
3503 - make sure make_default_mailpath() has a valid current_user struct
3504 before trying to construct the default mailpath
3509 - execute_builtin needs to call run_unwind_frame if the builtin is
3510 `source' or `eval' and we're not in a subshell rather than just
3511 calling dispose_builtin_env, because not all invocations copy
3512 the temporary_env to builtin_env, and nested calls to `.' require
3513 that the temporary env given to the first persist until that first
3514 call to `.' finishes
3517 - fix to history_delimiting_chars so that function definitions like
3524 are saved to the history correctly when command_oriented_history
3525 is enabled, but literal_history is not
3528 - when calling internal_error from pre_process_line, use "%s" as
3529 the format with history_value as the argument to avoid the
3530 problem with the failed history event containing printf escape
3536 - if shell_initialized is non-zero, don't line-buffer stderr and
3537 stdout in shell_initialize on SunOS5 -- see if this fixes the
3538 crashing problems for scripts without a leading `#! /bin/sh'
3543 - added diffs to _ignore_completion_names from Andreas Schwab to
3544 complete names that would otherwise be ignored with FIGNORE if
3545 they are the only possible completions. Define NO_FORCE_FIGNORE
3546 if you want this; it is not defined by default
3551 - changed the bug-bash address to bug-bash@gnu.org
3553 examples/loadables/Makefile.in
3554 - converted from `Makefile' with some boilerplate configure variables
3555 to find the source and build directories -- still requires some
3556 hand-editing to get the right CFLAGS and LDFLAGS for shared object
3560 - create examples/loadables/Makefile with `make makefiles'
3563 - create examples/loadables directory so `make makefiles' can write a
3567 - make sure initialize_groups_array always sets things up so that
3568 ${GROUPS[0]} is the user's primary group (current_user.gid)
3572 lib/readline/parens.c
3573 - change the time delay when showing matching parens from 1.5 sec to
3579 - isnetconn() should call getpeername(fd,...) instead of using 0
3580 (though fileno(stdin) should always be 0)
3582 support/config.guess
3583 - updates from master FSF copy
3588 - modified version of man2html to convert bash.1 into bash.html
3591 - simple Makefile to create man2html
3594 - make sure support/Makefile is created
3597 - make sure support/Makefile is created and cleaned
3600 - changes to suffix rules to say how to make .html from .1
3601 - `bash.html' is now a makefile target, created by man2html from
3602 bash.1 rather than being hand-modified
3604 lib/sh/itos.c, general.c
3605 - new file, itos() from general.c. This is here because the
3606 implementation of strerror in lib/sh/strerror.c uses itos()
3608 Makefile.in, lib/sh/Makefile.in
3609 - changes to add itos.c in libsh.a
3611 externs.h, general.h
3612 - moved extern declaration of itos() from general.h to externs.h
3615 - changes to BASH_LARGE_FILE_SUPPORT for the LFS64_* variables in
3619 - make sure configure sets CPPFLAGS in this file
3624 builtins/command.def
3625 - make sure get_standard_path returns the value of
3626 STANDARD_UTILS_PATH if _CS_PATH is defined, but confstr(3)
3627 returns 0, indicating that _CS_PATH does not have a defined
3631 - fixed bash_history_inhibit_expansion() so that extended globbing
3632 expressions like *.!(c) are not history expanded if extended_glob
3633 is non-zero (shopt -s extglob has been executed)
3638 - changed release status to `beta1'
3640 [bash-2.02-beta1 frozen]
3644 lib/readline/vi_mode.c
3645 - make sure _rl_vi_save_insert() gets a non-null UNDO_LIST pointer
3646 before trying to do anything with it
3649 - add a call to internal_warning from wait_for_job if the job is
3651 - changed notify_of_job_status to not report pipelines exiting due to
3652 SIGPIPE in non-interactive shells if the shell is compiled with
3653 -DDONT_REPORT_SIGPIPE
3656 - some fixes to try to avoid /tmp file races and surreptitious
3660 - changed the extended version info to show 1998 as the copyright year
3663 - fixes from Andreas Schwab <schwab@LS5.informatik.uni-dortmund.de>
3664 for compilation errors when the shell is configured --disable-alias
3665 but with dparen arithmetic enabled
3668 - fixes from Andreas Schwab <schwab@LS5.informatik.uni-dortmund.de> to
3669 make sure the input stream is popped correctly when performing an
3670 array assignment in the command argument to `bash -c', e.g.,
3674 - make `kill' with no arguments print a usage message and return a
3678 - fix so that rd_token doesn't dump core when trying to do alias
3679 expansion on a line containing an unclosed single quote (fix from
3680 Vasco Pedro <vp@di.fct.unl.pt>)
3683 - fix so that using a non-empty directory from CDPATH to construct
3684 the name of the directory to change to results in an absolute
3685 pathname of the new current working directory being displayed,
3686 as POSIX.2 specifies
3689 - a couple of small fixes to minimize /tmp file races -- the script
3690 is still raceable, the window is just smaller
3695 - make sure assign_in_env passes a malloc'd string to
3696 expand_string_unsplit, because some of the error code assumes that
3697 it is malloc'd and frees it (bug reported by Marko.Makela@HUT.FI)
3702 - changed the email addresses to use the @email texinfo tag
3705 - call reset_parser from the exit trap code before calling
3706 parse_and_execute, so reserved words are parsed correctly
3709 - make sure parameter_brace_patsub expands the pattern string as if
3710 the expression were not in double quotes, even if the entire
3711 expansion is enclosed in double quotes, so that quote removal
3712 on embedded double quotes is performed correctly (bug report from
3713 schwab@issan.informatik.uni-dortmund.de)
3717 support/config.guess
3718 - changes to allow Power PCs running Apple's Rhapsody to configure
3724 - changed release status to `beta2'
3726 [bash-2.02-beta2 frozen]
3731 - make sure command_substitute does not try to set the terminal's
3732 process group to a background job
3738 [bash-2.02 released]
3743 - make sure that rl_defun is not called for
3744 history-and-alias-expand-line unless both ALIAS and BANG_HISTORY
3751 - make sure that make_here_document allocates enough space for the
3752 first line of the here document, by using the line length +2
3753 (instead of 1000, which is what the old code did, and breaks if
3754 the first line of the here document is enough longer than 1000
3755 characters to cause other memory to be scribbled on)
3759 - when in posix mode, a value of "" for CDPATH should be treated the
3760 same as the current directory, not result in an error
3764 - change the mh_align member of `union mhead' to be of type double
3765 rather than a pointer, so that malloc will return (hopefully)
3766 8-byte aligned memory
3772 - add a new macro to check whether or not off_t is 64 bits
3777 - fixed a typo so the bash malloc is not compiled in on mips-sgi-irix6
3779 lib/readline/display.c
3780 - fix for readline redisplay if the prompt string is longer than the
3781 screen width and includes invisible characters
3785 - make_child should not set the terminal's process group to
3786 pipeline_pgrp if pipeline_pgrp == shell_pgrp (indicating that we
3787 are forking a child for a command substitution)
3791 - in execute_simple_command, in the child forked if there is a pipe
3792 or the command is asynchronous, set subshell_environment to
3793 SUBSHELL_ASYNC only if the command is asynchronous, SUBSHELL_FORK
3794 if there is a pipe in or out
3800 - upgraded to version 0.8 (from 0.5)
3803 - upgraded to version 1.52 (from 1.51)
3806 - config.sub now recognizes all the permutations of the system name
3807 that config.guess produces for alphas
3811 - changed BASH_TYPE_INT32_T, BASH_TYPE_U_INT32_T, and
3812 BASH_TYPE_PTRDIFF_T to avoid compiling a program; instead use
3813 the values determined by the AC_CHECK_SIZEOF tests to determine
3814 the default values to supply to AC_CHECK_TYPE
3817 - don't call AC_CHECK_TYPE({int32_t,u_int32_t,ptrdiff_t}) from
3818 configure.in; use the updated BASH_TYPE macros instead
3821 - if shell_execve fails, set ARGS to null because the realloc() call
3822 by shell_execve may have caused it to be reallocated and freed --
3823 we don't want to free the memory twice
3826 - fixes from ache@nagual.pp.ru to make fnmatch work for eight-bit
3827 characters when `isupper' and `islower' are used -- they were
3828 restricted to ASCII characters before, probably to work around
3829 some ancient, broken C libraries in which is{low,upp}er are valid
3830 only for ASCII characters and return bogus values otherwise
3836 - fixed a problem with the shell displaying the old working directory
3837 instead of the new one after changing to a directory found via
3838 $CDPATH when in physical mode (set -o physical)
3842 - make make_cond_command initialize the line number from the cond_node
3843 that's passed as an argument (not that it's used right now)
3846 - make sure that copy_cond_command copies the type of the cond command,
3847 since execute_cond_command uses that to decide what kind of test
3852 - make sure the for loop that processes the format string actually
3853 consumes arguments; otherwise process it only once to avoid
3854 infinite loops (e.g., `printf " " abc def ghi')
3856 - if the format string is empty after preprocessing by ansicstr,
3861 - use `diff -a' so the presence of a non-printing character in the
3862 output doesn't confuse diff into thinking the files are binary
3863 (test whether or not `diff' supports `-a' first)
3866 - keep $(LOCAL_LIBS) from being specified twice
3871 - a script to generate variables to do shared object configuration
3872 for the loadable builtin stuff
3875 - added a section for shared object configuration using an `eval'
3876 of the output of shobj-conf and substituting the generated values
3879 examples/loadables/Makefile.in
3880 - the system-specific shared object configuration variables are now
3881 substituted by configure
3886 - some changes for HPUX 9.x's peculiar handling of RLIMIT_FILESIZE
3887 - changed the limit retrieval functions to return an error code
3888 and the value in a reference argument to avoid use of RLIM_INVALID
3891 - new function, get_group_array(), which returns an array of
3894 examples/loadables/{id,printenv,sync,uname,whoami,push}.c
3895 - new loadable builtins
3898 - moved code that initializes $PPID into a new function, set_ppid()
3901 - extern declaration for set_ppid()
3906 - make sure that the `"' (double-quoted string) case of
3907 expand_word_internal calls string_list_dollar_at if we've expanded
3908 a double-quoted $@ so correct splitting on $IFS is done when
3909 the expansion is complete. We can't simply call string_list
3910 because that forces a space separator, and $IFS may not contain
3917 - broke the code that parses a symbolic mode out of symbolic_umask
3918 into a separate function that takes a symbolic mode and an initial
3919 set of bits to modify
3921 examples/loadables/mkdir.c
3922 - new loadable builtin
3927 - use the format string length provided by ansicstr() to process the
3928 format string, rather than testing for nullness, to handle NUL
3929 bytes in the expanded format string
3932 - changes so it can be built as both a regular builtin and a loadable
3933 builtin from the same source
3935 examples/loadables/Makefile.in
3936 - changes to build pushd.c from ${topdir}/builtins/pushd.def and then
3937 compile it with the correct flags to make it a loadable builtin,
3938 even if PUSHD_AND_POPD is not defined in config.h
3942 lib/readline/complete.c
3943 - use rl_completer_quote_characters instead of #ifdef SHELL/#endif
3944 code in make_quoted_replacement. This means complete.c no longer
3945 has any #ifdef SHELL code
3949 builtins/Makefile.in
3950 - `make clean' should remove mkbuiltins.o
3953 - all of the various `clean' targets need to descend into lib/sh
3954 and run the appropriate target there
3957 - changed to use the builtin getopt. The old long options are
3958 handled by prescanning the argument list looking for the long
3959 options, processing them, and taking them out of the list before
3960 passing it to internal_getopt()
3962 lib/readline/signals.c
3963 - removed #ifdef SHELL code -- job control signals and SIGTERM are
3964 always set in rl_set_signals, but are set to SIG_IGN if the old
3965 handler was SIG_IGN (as bash sets it)
3966 - new function rl_maybe_set_sighandler, which sets the signal
3967 disposition back to SIG_IGN if the old handler was SIG_IGN
3968 - removed #ifdef HANDLE_JOB_SIGNALS and #ifdef HANDLE_SIGTERM code
3970 lib/readline/rltty.c
3971 - removed #ifdef SHELL code -- set_winsize is always called
3972 to force the application to stop if it's not in the foreground
3973 before getting the tty attributes
3977 lib/readline/signals.c
3978 - readline now catches SIGQUIT and cleans up the tty before resending
3979 it to its container application (unless the calling application has
3980 set the disposition of SIGQUIT to be SIG_IGN)
3981 - rl_handle_sigwinch is now called rl_sigwinch_handler
3982 - rl_sigwinch_handler now calls rl_resize_terminal to fetch the
3983 screen size after a SIGWINCH
3984 - the sighandler_cxt struct for non-posix systems now includes
3985 sa_flags and sa_mask variables, for future use
3986 - new variable, rl_catch_signals, indicating that readline should
3987 install its own signal handlers for SIGINT, SIGTERM, SIGQUIT,
3988 SIGALRM, SIGTSTP, SIGTTIN, and SIGTTOU
3989 - new variable, rl_catch_sigwinch, indicating that readline should
3990 install its own SIGWINCH handler, which will chain to a calling
3991 application's SIGWINCH handler
3992 - new function, rl_free_line_state(), to free up variable state
3993 associated with the current line after receiving a signal
3994 - new function, rl_cleanup_after_signal(), to clean up the display
3995 and terminal state after receiving a signal
3996 - new function, rl_reset_after_signal(), to reinitialize the
3997 terminal state after a signal handler returns and readline
3999 - rl_set_signals and rl_clear_signals now look at the values of
4000 rl_catch_signals and rl_catch_sigwinch
4002 lib/readline/terminal.c
4003 - new function rl_resize_terminal (), to reset readline's idea of
4004 the screen size after a SIGWINCH
4006 lib/readline/readline.h
4007 - extern declarations for rl_resize_terminal(), rl_free_line_state(),
4008 rl_cleanup_after_signal(), rl_reset_after_signal()
4009 - extern declarations for rl_catch_signals and rl_catch_sigwinch
4012 - new functions, get_env_value(char *) and get_home_dir(void) to
4013 satisfy references from the tilde and readline libraries when
4014 they are compiled as part of bash
4017 - rely on extern declarations of get_env_value and get_home_dir;
4018 there is no more #ifdef SHELL code
4020 lib/readline/shell.c
4021 - implementation of get_home_dir that uses getpwuid() to satisfy
4022 references from tilde.c when not compiled as part of bash
4023 - removed savestring()
4024 - removed #ifdef SHELL/#endif pair -- all of these functions will be
4025 resolved from bash when readline is linked into bash
4027 lib/readline/savestring.c
4028 - new file, with function definition for savestring() for backwards
4031 Makefile.in, _distribution
4032 - bumped things up to bash-2.03-alpha
4036 lib/readline/rlconf.h
4037 - removed #ifdef SHELL/#endif pair, so the callback stuff will be
4038 compiled into libreadline, but never linked into bash (since it's
4042 - added new `--with-installed-readline' option to allow readline to
4043 be linked with an already-installed version -- this will probably
4044 not work with versions of readline prior to 2.3 (libreadline.so.4)
4045 [THIS IS STILL UNDOCUMENTED]
4048 - changed necessary variables to allow the `--with-installed-readline'
4049 option to work; shared and static libraries are supported
4053 lib/readline/display.c
4054 - _rl_save_prompt is now rl_save_prompt; _rl_restore_prompt is now
4057 lib/readline/readline.h
4058 - extern declarations for rl_save_prompt and rl_restore_prompt
4060 lib/readline/{search,isearch,readline,display}.c
4061 - converted calls to _rl_{save,restore}_prompt () to use new public
4064 lib/readline/doc/rltech.texinfo
4065 - documented new public functions rl_{save,restore}_prompt
4069 lib/readline/readline.c
4070 - new hook function variable, rl_pre_input_hook. If non-zero, it's
4071 called from readline_internal_setup just before it returns and
4072 readline starts reading input
4074 lib/readline/readline.h
4075 - extern declaration for rl_pre_input_hook
4077 lib/readline/doc/rltech.texinfo
4078 - documented new variable rl_pre_input_hook
4082 lib/readline/complete.c
4083 - new hook function variable, rl_completion_display_matches_hook.
4084 If non-null, this function is called when readline would normally
4085 display the list of completion matches
4087 lib/readline/readline.h
4088 - extern declaration for rl_completion_display_matches_hook
4090 lib/readline/doc/rltech.texinfo
4091 - documented rl_completion_display_matches_hook
4093 lib/readline/readline.c
4094 - if RL_LIBRARY_VERSION is not defined, define it to 4.0 to match
4095 the version number of the shared libraries
4097 lib/readline/doc/{hist,rlman}.texinfo
4098 - changed the version and edition to 4.0 to match the library version
4100 support/config.guess
4101 - added case clause for matching UnixWare 7 from SCO (SVR5) -- further
4103 [These fixes were in a usenet posting from hops@sco.com]
4106 - added case clauses to recognize various aliases for SCO Open Server
4109 - broke the code that canonicalizes unixware into unixware2 and
4110 unixware7 clauses (multiple places)
4112 - added clause to recognize `sysv5' for SVR5
4113 [These fixes were in a usenet posting from hops@sco.com]
4117 - add `-b elf' to LOCAL_CFLAGS for sco3.2v5* to allow dynamic linking
4118 (and loadable builtins)
4119 - add AC_DEFINE(SVR5) on SVR5 (unixware 7)
4122 - add #undef SVR5, set by configure
4127 - line-buffer stdout and stderr in shell_initialize only if
4128 shell_initialized is 0 on all systems, not just SunOS 5
4132 - script to print out the version number of any installed
4136 - only allow --with-installed-readline if the version of the
4137 installed readline library is 4.0 or greater
4141 lib/readline/complete.c
4142 - broke the code that actually displays a list of completion
4143 matches on the output stream into a separate public function,
4144 rl_display_match_list, so it can be called from the hook
4145 function rl_completion_display_matches_hook.
4147 lib/readline/readline.h
4148 - new extern declaration for rl_display_match_list
4150 lib/readline/rltech.texinfo
4151 - documented rl_display_match_list
4153 configure.in,Makefile.in
4154 - --enable-static-link now creates a STATIC_LD variable in Makefile
4155 rather than adding to LDFLAGS directly. LDFLAGS now includes
4161 - OLDPWD is now auto-exported
4162 - broke the code out of bindpwd() that updated the value of PWD in
4163 the export environment in-place and made it general, so it can
4164 be used for OLDPWD, too (this should be made *more* general, and
4165 moved to variables.c)
4170 - moved builtins/cd.def:export_pwd_var to here, renamed it to
4171 update_export_env_inplace
4172 - converted put_command_name_into_env to just call
4173 update_export_env_inplace
4174 - made dummy variable for OLDPWD, marked as invisible and exported,
4175 in initialize_shell_variables
4178 - extern declaration for update_export_env_inplace
4181 - changed calls to export_pwd_var to update_export_env_inplace
4184 - added missing return in rl_unbind_function_in_map
4185 - changed _rl_read_file to check whether or not `read' returns
4186 < 0 rather than < file_size
4187 - _rl_read_init_file needs to free `openname' after calling
4188 _rl_read_file, since it's not used again
4190 lib/readline/callback.c
4191 - bogus extern declaration for `readline_internal_startup', should
4192 be readline_internal_setup
4194 lib/readline/histfile.c
4195 - read_history_range now checks whether read(2) returns < 0 rather
4196 than checking the return value against the file size
4198 lib/readline/parens.c
4199 - whoops -- timer.tv_usec is *micro* seconds, not milliseconds
4201 lib/readline/readline.c
4202 - initialize `eof' to 1 in readline_internal_charloop
4207 - if we're configuring with an installed version of readline, set and
4208 have configure substitute RL_INCLUDE to `-I$(includedir)', so the
4209 build process uses the installed readline include files as well as
4212 Makefile.in, builtins/Makefile.in
4213 - add @RL_INCLUDE@ in the appropriate places, substituted by configure
4215 lib/readline/{history,readline}.h
4216 - add `extern "C"' wrapper if `__cplusplus' is defined
4220 - add prototypes to extern declaration for fnmatch()
4222 lib/readline/rlstdc.h
4223 - link to ../posixheaders/stdc.h (in readline lib with different name
4224 for benefit of standalone readline library installation)
4226 lib/readline/{history,keymaps}.h
4228 - add prototypes to all of the extern function declarations
4230 lib/readline/history.h
4231 - the `data' member of a HIST_ENTRY is now a histdata_t, which is
4232 either a void * (ansi c) or a char * (k&r c)
4234 lib/readline/readline.c
4235 - changed calls to replace_history_entry to pass a histdata_t as the
4241 - make sure that copy_cond_command doesn't blindly try to copy
4242 com->op, since that will be null for AND and OR nodes, at least
4245 lib/readline/vi_mode.c
4246 - added missing second argument to rl_vi_[fbe][Ww]ord(), since
4247 they're used as pseudo-bindable commands (they appear in the
4248 default funmap) as well as utility functions
4250 lib/readline/readline.h
4252 - added prototypes for functions from vi_mode.c, util.c, terminal.c,
4253 search.c, util.c, undo.c, readline.c, parens.c, macro.c, kill.c,
4254 keymaps.c, isearch.c, input.c, funmap.c, display.c, complete.c,
4256 - added extern declarations for functions from rltty.c
4258 lib/readline/{readline,util}.c
4259 - rl_refresh_line now takes the standard two arguments for bindable
4260 commands; changed callers
4263 - small cleanups for incorrect arguments, etc. uncovered by use of
4267 - small cleanups for incorrect arguments, etc. uncovered by use of
4273 - cast result of strsignal() to (char *) for the benefit of broken
4274 Cray UNICOS machines
4277 configure.in,aclocal.m4
4278 - new test, BASH_TYPE_BITS64_T, used to find out what basic type is
4279 64 bits long; defaults to `double'
4280 - call AC_CHECK_SIZEOF(double)
4283 - #define for bits64_t, undef by default
4288 - changed BASH_TYPE_BITS64_T so that it checks the size of a char *
4289 first, before trying sizeof(double)
4291 lib/readline/doc/rluser.texinfo,doc/{bash.1,readline.3}
4292 - changed default binding for tilde-expand to M-&, since bash
4293 overrides M-~ to force username completion
4296 - fixed an off-by-one error in hostnames_matching that exhibited
4297 itself when an exact multiple of 16 hostnames matched (fix
4298 from <davidg@nikhef.nl>)
4303 lib/readline/readline.c
4304 - the maximum numeric argument is now 1000000
4307 - fixed a bug in bash_directory_completion_hook that caused memory
4308 to be freed twice if a directory name containing an unset
4309 variable was completed and `set -u' had been set
4312 - on LynxOS, add a -DRECYCLES_PIDS to LOCAL_CFLAGS
4315 - make sure that the changes to make the shell fork early when
4316 run in the background do not cause commands such as `%1 &'
4319 - if RECYCLES_PIDS is defined, execute_command_internal sets
4320 last_made_pid to NO_PID after waiting for a foreground process,
4321 if the return status is 0 (fix from plai@Lynx.COM (Paul Lai))
4324 - fixes from Andreas Schwab to rl_yank_last_arg that make it
4327 lib/readline/input.c
4328 - fixes from Donald Beaudry <donb@sgi.com> to make the input buffering
4329 and rl_stuff_char work right when the input buffer is nearly full
4330 (probably not a problem with keyboard input, but maybe a problem
4331 with programmers attempting to use rl_stuff_char to preload the
4337 - fix to decode_prompt_string so that the \$ expansion quotes the `$'
4338 so it won't be processed by subsequent parameter expansion
4339 - change read_token_word so a $$ appearing in a token is recognized
4340 and parsed immediately, so a single or double quote after the
4341 second `$' doesn't cause ANSI-C expansion or locale translation
4342 (bug report from haertel@ichips.intel.com)
4346 lib/readline/display.c
4347 - fixed a bug that caused core dumps in xrealloc if the prompt was
4348 longer than 1024 characters
4352 builtins/mkbuiltins.c
4353 - if the number of characters read from the .def file is less than
4354 the file size reported by `stat', and the read completed without
4355 errors, reset the file size to avoid writing garbage at the end
4356 of the generated .c file (needed on WIN32 systems, doesn't hurt
4361 CWRU/empty-for-wordlist
4362 - patch from Brian Fox for parse.y to allow bash to accept an empty
4363 `wordlist' after the `in' keyword in a for statement
4368 - corrected the synopsis of the `for' and `select' statements to
4369 indicate that the semicolon (or newline) after the optional
4370 `in words' is required
4372 [bash-2.02.1 released]
4376 lib/readline/display.c
4377 - make sure visible_length is initialized to 0 in rl_expand_prompt.
4378 Fix from Gerhard Niklasch <nikl@mathematik.tu-muenchen.de>.
4381 - make sure that quotes are removed from the filename being globbed
4382 in glob_vector() before calling the GLOB_TESTNAME macro if there
4383 are no globbing characters in the pattern
4386 - make sure that builtins.1 is looked for in $(srcdir) when running
4387 `make install' (it's still commented out, though)
4392 - if PROMPT_STRING_DECODE is not defined, define PPROMPT (the primary
4393 prompt string) as "$ "
4396 - if PROMPT_STRING_DECODE is not defined, and current_user.euid == 0,
4397 PS1 defaults to "# ", otherwise it defaults to `primary_prompt'
4400 - fixed email address prep.ai.mit.edu -> gnu.org
4405 - add `solaris2' as a possible OS name, treated the same as sunos5
4410 - changed maybe_make_restricted() so that $ENV and $BASH_ENV are
4411 read-only variables in a restricted shell
4413 doc/{bash.1,bashref.texi}
4414 - added ENV and BASH_ENV to the list of readonly variables in
4418 - added `do', `then', `else', `{', and `(' to the list of keywords
4419 that may precede the `time' reserved word
4422 - added sanity checks to timeval_to_secs and clock_t_to_secs so
4423 that if the fractional part is >= 1000, 1 is added to the
4424 seconds and 1000 is subtracted from the fractional seconds
4429 - use $(CC_FOR_BUILD) to build mksignames
4432 - changes to allow cross-building for BeOS as well as cygwin32
4434 cross-build/{beos-sig.h,x86-beos.cache}
4435 - new files for cross-compiling for BeOS
4440 - changed rule for version.h to use && instead of if-then-else-fi to
4441 make sure the recipe fails if mkversion.sh fails
4444 - beos does not use the GNU malloc
4447 - broke itos into inttostr(i, buf, len) and itos(i), which calls
4448 inttostr and returns a newly-allocated string with the result
4450 support/mksignames.c
4451 - define `SIGKILLTHR' if system include files define it
4454 - extern declaration for inttostr(int, char *, int)
4459 - include stdc.h before bashansi.h
4462 - make sure that execute_cond_node treats `=' the same as `=='
4466 variables.c, print_cmd.c
4467 - changed some calls to itos to use inttostr instead
4469 cross-build/x86-beos.cache, {execute_cmd,general,shell,trap}.c
4470 - some changes for BeOS (from fnf@ninemoons.com)
4472 lib/posixheaders/memalloc.h
4473 - changes to handle case where we're using both gcc and the C
4474 version of alloca(), or if we have alloca.h and we're using
4475 the C version of alloca() (from fnf@ninemoons.com)
4478 - if bcopy or bzero are #defines, #undef them before defining
4479 replacement functions
4481 support/config.guess
4482 - recognize AmigaOS (from fnf@ninemoons.com)
4483 - recognize BeOS running on various machines
4484 (from fnf@ninemoons.com)
4487 - change basic_machine definition for amiga; added amigaos
4488 (from fnf@ninemoons.com)
4489 - changed definitions for MIPS machines running Linux (from
4491 - recognize `beos' as a valid operating system
4492 (from fnf@ninemoons.com)
4493 - changed OS for *-cbm to `amigaos' rather than `amigados'
4494 (from fnf@ninemoons.com)
4496 examples/functions/autoload.v3
4497 - a new version, from Mark Kennedy <mtk@ny.ubs.com>
4499 lib/readline/readline.c
4500 - new function, rl_delete_or_show_completions, like tcsh editing
4501 function delete-char-or-list
4503 lib/readline/readline.h
4504 - new extern declaration for rl_delete_or_show_completions
4506 lib/readline/funmap.c
4507 - new bindable name `delete-char-or-list', like tcsh
4509 lib/readline/doc/rluser.texinfo, doc/{bash.1,readline.3}
4510 - documented new delete-char-or-list command
4513 - fix full_pathname to keep it from generating things like
4514 //foo when the current directory is /
4519 - fixed the help text for the -e option
4524 - added a clause for AIX 4.2 systems running gcc -- just the
4525 standard gcc stuff for shared objects, but it has to come
4526 before the other AIX 4.2 clause
4531 - some changes so that `set -e' is turned off while executing
4537 - new variable, `restricted_shell', non-zero if the shell was
4538 started in restricted mode
4541 - extern declaration for restricted_shell
4544 - new function, shell_is_restricted, returns 1 if the shell is
4545 supposed to be restricted based on the basename of $0 or the
4547 - set restricted_shell to the value returned by shell_is_restricted
4548 before executing the startup files
4551 - extern declaration for shell_is_restricted
4554 - new shopt variable, restricted_shell, indicates whether the shell
4555 was restricted at startup -- useful in startup files
4557 doc/{bash.1,bashref.texi}
4558 - documented new restricted_shell shopt option
4563 - new file, replacement for rename(2) if the OS doesn't provide it
4565 configure.in,config.h.in,Makefile.in,lib/sh/Makefile.in
4566 - machinery for including rename.o in libsh.a
4569 - make sure that set_tty_state returns a value
4571 builtins/mkbuiltins.c
4572 - use a call to rename(2) instead of a link/unlink pair
4575 - don't #define bcopy if bcopy is already defined
4577 lib/readline/histfile.c
4578 - add a call to ftruncate for BeOS, which ignores the O_TRUNC flag
4581 lib/readline/input.c
4582 - make rl_getc loop if read returns -1/EINTR on BeOS
4585 - set ARFLAGS and substitute it into the Makefiles
4587 {,builtins,lib/{glob,malloc,readline,sh,termcap,tilde}}/Makefile.in
4588 - ARFLAGS is now substituted by configure
4589 - use ARFLAGS in rules that create libraries using $(AR)
4592 - fixed bug that caused a core dump when a modifier was supplied
4593 in the format string without a conversion character (e.g. `%h')
4598 - if filenames starting with a dot don't have to be matched
4599 explicitly (e.g., after a `shopt -s dotglob'), don't match
4600 `.' or `..' in any case
4603 - make sure that array assignments don't show up in the history list
4604 (fix from Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>)
4606 lib/readline/complete.c
4607 - fix to rl_menu_complete so it inserts a single completion properly
4608 when a word matches only one filename
4613 - difftimeval should zero out the tv_usec field if the tv_sec field
4615 - addtimeval should check for tv_usec being == 1000000 and add one
4621 - fix to expand_word_internal to prevent non-whitespace IFS characters
4622 from causing word splitting if they are not the results of an
4623 expansion (not exactly right yet, but I think it's the result of a
4624 problem with the ${...} end-brace-matching code in the parser)
4629 - new flag for parse_matched_pair -- P_FIRSTCLOSE -- which makes it not
4630 count and match additional construct open characters
4631 - change calls to parse_matched_pair when matching braces in
4632 ${...} constructs (both unquoted and within double quotes) to
4633 specify the P_FIRSTCLOSE flag to match POSIX.2 requirements
4636 - changed fix from 9/25, now that the parser problem is fixed
4641 - change expansion of list of words between (...) in array assignments
4642 to include pathname generation in assign_array_var_from_string
4644 doc/{bash.1,bashref.texi}
4645 - clarified behavior of the shell at startup if running setuid, with
4646 and without the -p option supplied
4651 - change default open(2) mode to 0600 instead of 0666 for `privacy
4656 lib/readline/display.c
4657 - fixed a problem with displaying tabs after newlines, from
4659 - in update_line, if we are printing over existing material,
4660 only call space_to_eol or _rl_clear_to_eol if lendiff is non-zero
4661 - when moving the cursor in _rl_move_cursor_relative, only call
4662 _rl_backspace if the current cursor position is strictly greater
4663 than the desired cursor position
4668 - LC_ALL is no longer set automatically when LANG is assigned a value
4671 - renamed to config-{top,bot}.h, respectively
4674 - include config-top.h and config-bot.h
4677 - things now depend on config-top.h and config-bot.h
4680 - minor changes to extract_dollar_brace_string and char_is_quoted to
4681 allow things like "${PIP[TAB] to perform correct variable completion
4685 builtins/Makefile.in
4686 - add $(PROFILE_FLAGS) to the make recipe that creates `mkbuiltins',
4687 so configuring with --enable-profiling works right
4692 - documented the new --with-installed-readline option
4694 [bash-2.03-alpha1 frozen]
4698 builtins/reserved.def
4699 - fixed help text for { ... } to make it clear that a semicolon is
4700 required before the closing brace
4705 - in decode_signal, don't bother calling strcasecmp if
4706 signal_names[sig] is null or empty
4711 - make sure RL_LIBDIR and HIST_LIBDIR are assigned values even if
4712 readline or history is configured out of the shell, so the -L
4713 options have arguments in the link command
4716 - make test_syntax_error cause test to return a status > 1, to
4717 conform to POSIX.2 4.62.8
4720 - make sure the SYNOPSIS section indicates that programmers should
4721 include <stdio.h> before <readline.h>
4726 - install with explicit mode of 0755
4731 - make sure that a missing `]' makes `[' exit with status 2, to
4732 conform to POSIX.2 4.62.8
4735 - new word flag: W_NOGLOB, meaning to not perform globbing
4738 - fix_assignment_statements now turns on the W_NOGLOB flag for
4739 arguments to `assignment builtins' that have W_ASSIGNMENT set
4742 - expand_word_internal needs to preserve the W_NOGLOB flag from
4743 the word being expanded to the word being returned
4744 - glob_expand_word_list does not call shell_glob_filename for a
4745 word with W_NOGLOB set
4748 - print_shopt is now void
4751 - machines running Rhapsody don't use the bash malloc
4752 - pass host_vendor to the Makefiles with AC_SUBST
4754 support/config.guess
4755 - Rhapsody is really rhapsody, not nextstep
4758 - add rhapsody to the list of supported configurations
4761 - pass CONF_HOSTTYPE, CONF_OSTYPE, and CONF_MACHTYPE as -D options
4762 in SYSTEM_FLAGS, to indicate that they came from the configuration
4764 - set VENDOR variable from host_vendor configuration variable
4765 - pass CONF_VENDOR as part of SYSTEM_FLAGS
4768 - define HOSTTYPE, OSTYPE, and MACHTYPE as CONF_HOSTTYPE, CONF_OSTYPE,
4769 and CONF_MACHTYPE, respectively
4773 doc/{bashref.texi,bash.1}
4774 - updated description of `read' to clarify the -r option and its
4775 effect on backslash escaping
4779 examples/loadables/{ln,unlink}.c
4780 - new loadable builtins
4785 - some fixes to handle extended glob patterns immediately following
4789 - updated with cases from bug report fixed today
4792 - udpated stanza for aix 4.2 with gcc, based on information from
4796 - changes to add the correct linker options to allow dynamic linking
4797 when using gcc on AIX 4.2, instead of insisting on the AIX C
4800 examples/misc/aliasconv.{bash,sh}
4801 - changes to handle aliases with embedded single quotes
4805 lib/readline/complete.c
4806 - postprocess_matches should call compute_lcd_of_matches with an
4807 argument of `t' instead of `text'
4808 - postprocess_matches should never call ding(); leave that for the
4810 - postprocess_matches no longer needs `text' as the first argument
4811 - rl_complete_internal needs to call ding() if postprocess_matches
4812 returns 0, since postprocess_matches no longer does it
4813 - rl_complete_internal can now free `text' immediately after calling
4814 gen_completion_matches, since it's no longer used
4819 - make sure redirections following compound commands have a space
4820 separating them from the command
4825 - changed canonicalize_pathname so that if the result path begins
4826 with `//', it will be changed to `/' if and only if the original
4827 path did not begin with `//' (there has to be a non-slash after
4828 the leading `///' in the original path)
4832 builtins/evalstring.c
4833 - augment the test for turning on CMD_NO_FORK to make sure that
4834 parse_and_execute_level == 1. That takes care of things like
4836 bash -c 'for f in 1 2 3; do eval "/bin/echo \"$f\"" ; done'
4838 only printing one line of output
4843 - add commented-out #define for NON_INTERACTIVE_LOGIN_SHELLS so
4844 that users may, if they choose, make things like
4846 #! /bin/bash --login
4848 work in shell scripts
4853 - changes to the way jobs are reaped when the shell is not
4856 o notify_of_job_status no longer marks dead jobs as
4857 notified if they did not exit due to a signal;
4858 o changed mark_background_jobs_as_notified to take an
4859 argument `force': if zero, we only mark enough
4860 dead jobs as notified to keep CHILD_MAX jobs in the
4861 jobs list, as POSIX.2 specifies. If non-zero, mark
4862 all dead jobs as notified;
4863 o wait_for_background_pids marks all dead jobs as
4864 notified when it has finished waiting for everything,
4865 since the only thing that calls it is the `wait' builtin;
4866 o wait_for_single_pid marks a job as notified after it
4867 has completed, since the only things that call it are
4868 wait_for_background_pids and the `wait' builtin
4869 o wait_for_job marks the job as notified after the last
4873 - change execute_subshell_builtin_or_function to check
4874 subshell_environment and pipe_out to decide whether or not to fork
4875 if builtin == jobs_builtin, since the early-forking code added in
4876 bash-2.02 means that the piping has probably already been done
4881 - changes to make avar=((...)) a syntax error instead of ignoring
4882 the nested parens and treating it as an array assignment
4885 - changed run_startup_files so that any shell, whether or not it is
4886 interactive, will run the login shell startup files when given the
4887 --login option. This happens only when not in posix mode.
4890 - changes to handle Tenon's MachTen, whose dlclose() does not return
4894 - changed gmatch so that when it calls extmatch, it removes FNM_PERIOD
4895 from the flags if it's not matching at the start of the string.
4896 This fixes the problem of `@' and `+' extended-glob subpatterns
4897 containing bracket expressions treating `.' specially when matching
4898 a portion of the string starting with `.'
4901 - removed define for NON_INTERACTIVE_LOGIN_SHELLS, since it's no longer
4906 lib/readline/complete.c
4907 - change rl_complete_internal and rl_menu_complete to check
4908 rl_filename_completion_desired to decide whether or not we're
4909 completing filenames instead of checking whether the attempted
4910 completion function is filename_completion_function.
4911 filename_completion_function sets rl_filename_completion_desired,
4912 so this shouldn't break anything -- just allow postprocessing of
4913 matches for user-supplied filename completion functions that don't
4914 call filename_completion_function
4916 lib/readline/display.c
4917 - new function, _rl_erase_entire_line, which erases the entire line,
4918 no matter where the cursor is, and puts the cursor at the beginning
4919 of the (newly-empty) line
4921 lib/readline/readline.c
4922 - new application-level variable, rl_erase_empty_line, which, if
4923 non-zero, tells readline to erase the contents of the current line,
4924 prompt and all, if the only character typed to an otherwise-blank
4925 line is bound to rl_newline. Requested by the Cygnus GDB folks.
4926 - change to rl_newline to suppress the call to _rl_update_final if
4927 rl_erase_empty_line is non-zero, and rl_point == rl_end == 0, since
4928 _rl_update_final calls crlf()
4929 - change to readline_internal_charloop to call _rl_erase_entire_line
4930 if newline was the only thing typed on an otherwise-empty line
4932 lib/readline/readline.h
4933 - extern declaration for rl_erase_empty_line
4935 lib/readline/doc/rltech.texinfo
4936 - documented new rl_erase_empty_line variable
4941 - changed RELSTATUS to `beta1'
4943 [bash-2.03-beta1 frozen]
4947 doc/{bash.1,bashref.texi}
4948 - added description of `test -h'; equivalent to `test -L'
4953 - SHOBJ_LDFLAGS should be those options to ld which are common
4954 between building dynamically loadable shared objects and shared
4956 - added two new variables: SHOBJ_XLDFLAGS, which are ld options
4957 specific to building dynamically loaded shared objects, and
4958 SHLIB_LIBS, which are other libraries against which shared libraries
4959 should be linked. These are for the benefit of AIX 4.2; other
4960 stanzas do not need to be changed.
4963 - add call to AC_SUBST for SHOBJ_XLDFLAGS
4965 examples/loadables/Makefile.in
4966 - SHOBJ_XLDFLAGS is now substituted by configure
4967 - $(SHOBJ_LDFLAGS) -> $(SHOBJ_LDFLAGS) $(SHOBJ_XLDFLAGS) in all
4968 recipes that build loadable builtins
4972 support/config.{guess,sub}
4973 - changes for NEC SX4 machines running SUPER-UX (?). Info from
4974 Nicholas Clark <nick@flirble.org>
4977 - new bindable variable, `isearch-terminators', which is the list of
4978 characters that will terminate an incremental search without
4979 subsequently executing the character as a command
4981 lib/readline/isearch.c
4982 - changes to incorporate the new isearch-terminators bindable variable;
4983 uses new private readline variable _rl_isearch_terminators
4984 (suggested by Brian Fox)
4986 doc/{bash.1,readline.3}, lib/readline/doc/rluser.texinfo
4987 - documented new `isearch-terminators' settable variable
4989 lib/readline/complete.c
4990 - new convenience function, free_match_list, called from
4991 rl_complete_internal
4996 - changed the calls to AC_MSG_ERROR in the cross-compiling sections
4997 to AC_MSG_WARN, since AC_MSG_ERROR can cause configure to abort
4999 examples/functions/which
5000 - new function, emulation of `which' as it appears in FreeBSD
5004 lib/readline/readline.c
5005 - new bindable function: rl_rubout_or_delete. Does rl_rubout if
5006 rl_point is at the end of the line, or rl_delete if not. This
5007 is intended to mimic the Motif/Netscape/GNOME behavior of the
5008 DEL character, and can be bound to delete to get that behavior
5010 lib/readline/readline.h
5011 - new extern declaration for rl_rubout_or_delete
5013 lib/readline/funmap.c
5014 - bound the name `forward-backward-delete-char' to
5015 rl_rubout_or_delete (currently not bound to any keys)
5017 lib/readline/doc/manvers.texinfo
5018 - new file with readline manual version information, to mantain
5019 consistent numbering between readline and history manuals
5021 lib/readline/doc/{rlman,hist}.texinfo
5022 - @include manvers.texinfo for version information
5023 - moved the @dircategory and and @direntry directives inside
5025 - changed copyrights to 1988-1999
5027 doc/Makefile.in, lib/readline/doc/Makefile.in
5028 - texi2html is now called with -menu (to handle the texinfo menus)
5029 and -monolithic (to include the table of contents in the generated
5030 HTML file instead of putting it in a separate file
5031 - changed recipes to remove references to TOC html files
5034 - include <string.h> or <strings.h> as appropriate for strchr()
5040 - don't print bare words when printing conditional expressions in
5041 print_cond_node, use cprintf("%s", cond->op->word)
5044 - in separate_out_assignments, if VARLIST is non-null on function
5045 entry, free it up to clean up after a previous error longjmp
5050 - make sure the case clause that disables the bash malloc on alpha
5051 machines catches things like `alphaev56' as well as `alpha'
5055 lib/readline/histlib.h
5056 - new error message code: NO_PREV_SUBST
5058 lib/readline/histexpand.c
5059 - handle NO_PREV_SUBST with appropriate error message in hist_error
5060 - in history_expand_internal, if the `s' or `&' case results in a
5061 null or empty LHS, return NO_PREV_SUBST
5064 - new interface: command_error(func, code, e, flags); intended to
5065 collect command-related errors in one place
5066 - new interface: command_errstr(code); returns a string describing
5070 - extern declarations for command_error and command_errstr
5073 - possible values for CODE in calls to command_error and command_errstr
5075 {shell,print_cmd,make_cmd,execute_cmd,dispose_cmd,eval}.c ,builtins/evalstring.c
5076 - changed some calls to programming_error to use command_error
5081 - if --enable-profiling is specified on a solaris2 machine, don't
5082 turn on enable-static-link, since it's very hard to build a
5083 static binary on solaris2 and gprof does not (apparently) require it
5085 builtins/getopts.def
5086 - add calls to sh_getopt_restore_state so the state is restored each
5087 time getopts is called. This protects us against the behavior of
5088 some mallocs, which causes `nextchar' to be set to garbage in
5089 getopt.c when a function is called between calls to getopts
5093 lib/readline/complete.c
5094 - if postprocess_matches returns 0 in rl_complete_internal, reset
5095 completion_changed_buffer to 0 before returning, since nothing
5101 - fixed pat_subst so that null patterns with a `#' specifier prefix
5102 the string to be substituted on with the replacement, and null
5103 patterns with a `%' specifier append the replacement to the string
5104 to be substituted on
5106 doc/{bash.1,bashref.texi}
5107 - corrected a small error in the description of parameter pattern
5110 support/mksignames.c
5111 - SIGINFO means something else on sequent systems
5116 - fix to execute_simple_command to keep a child process from getting
5117 a bad value of last_asynchronous_pid when the shell forks early
5122 - changed RELSTATUS to `beta2'
5126 [bash-2.03-beta2 released]
5130 tests/{cprint.{tests,right},run-cprint}
5131 - new test to exercise the command printing and copying code --
5132 hopefully this will avoid things like the `conditional commands
5133 in functions make the shell abort' problem
5138 - if MACHTYPE is not defined, use CONF_MACHTYPE if it's defined
5143 - if READLINE is defined, we need an extra pair of braces around
5144 the `while' loop that reads from fd 0 if the -e option is
5145 supplied, otherwise the code erroneously tests the value of
5146 `retval', which is not set when using readline
5151 - make sure that fc closes `stream' before calling fc_execute_file
5156 - don't bother opening and closing the file of commands before
5157 calling fc_execute_file, since parse_and_execute will write the
5158 commands to the history file for us
5161 - changed release status to `release'
5166 - change to special_case_tokens so that `time' is not recognized
5167 as a reserved word while the parser is parsing a case statement
5168 pattern list (if `time' is the first pattern, the last read
5169 token will be newline, which time_command_acceptable says is OK
5170 to start a pipeline)
5173 - some changes to the POSIX_GLOB_LIBRARY code (often unused)
5176 - a couple of changes for Interix (nee OPENNT)
5177 - added code that handles systems without a third argument to main();
5178 initializing `env' from `environ', conditionalized on a cpp define
5181 configure.in, config.h.in
5182 - check for the presence of sbrk(2); define HAVE_SBRK if found
5185 - don't do the space allocated computation when malloc or realloc
5186 fails if HAVE_SBRK is not defined
5189 - new configure variable, MAKE_SHELL, defaults to /bin/sh
5191 Makefile.in,{builtins,doc,support,lib/{glob,malloc,readline,sh,termcap,tilde},examples/loadables}/Makefile.in
5192 - set SHELL from @MAKE_SHELL@
5194 lib/posixheaders/posixjmp.h
5195 - Don't override defines for setjmp and longjmp in <setjmp.h> on
5196 Internix (nee OPENNT)
5198 lib/readline/complete.c
5199 - Interix (OPENNT) doesn't do username completion
5202 - on Interix/OPENNT ($host_os == interix* or opennt*), add
5203 -DNO_MAIN_ENV_ARG to LOCAL_CFLAGS
5204 - on Interix/OPENNT, set MAKE_SHELL to $OPENNT_ROOT/bin/sh rather
5205 than a straight /bin/sh
5207 cross-build/opennt.cache
5208 - a `configure' cache file for Interix/OPENNT; not necessarily
5209 for cross-compiling, but this is where the other system cache
5212 [bash-2.03 released]
5217 - changed OPENNT_ROOT to INTERIX_ROOT for building on Interix
5219 support/config.guess
5220 - added two stanzas for Interix running on alpha and intel hardware
5225 - if PROMPT_STRING_DECODE is not defined, #undef PPROMPT before
5226 redefining it, to avoid warning messages
5229 - set jobs_hack in execute_subshell_builtin_or_function only if
5230 JOB_CONTROL is defined
5235 - fixed an obscure bug caused by a race condition in run_pending_traps.
5236 Read the comments in the source code for a full description of the
5237 problem and solution
5242 - new test, BASH_STRUCT_TIMEVAL, which tries to compile a code
5243 fragment that includes <sys/time.h> and <time.h> as appropriate
5244 and defines HAVE_TIMEVAL if the compile succeeds
5247 - call BASH_STRUCT_TIMEVAL rather than running a pair of
5248 AC_HEADER_EGREPs on sys/time.h and time.h
5250 lib/readline/histfile.c
5251 - include "posixstat.h" rather than <sys/stat.h>
5252 - in history_truncate_file, only try to truncate if the history file
5258 - changed BASH_STRUCT_TIMEVAL back to using a pair of
5259 AC_EGREP_HEADERs instead of compiling a program fragment
5261 lib/readline/readline.c
5262 - readline_internal_charloop should cast the first argument to
5263 _rl_dispatch to `unsigned char' to avoid problems with negative
5264 array indices on systems where signed chars are the default
5267 - instead of doing a sequence of next_history() calls in
5268 rl_yank_nth_arg_internal, save and restore the history
5269 position explicitly after finding the correct entry. This
5270 attempts to ensure that rl_yank_nth_arg leaves the history
5271 pointer set to the same position as when it was called.
5272 Fix from Vasco Pedro <vp@di.fct.unl.pt>
5277 - broke code that opens file for redirection in do_redirection_internal
5278 into a separate function: redir_open(path, flags, mode, ri)
5281 - changed STREQN so that it evaluates to 1 (strings are equivalent)
5282 if N == 0, to match the behavior of strncmp
5285 - new file, zwrite() from builtins/evalstring.c
5287 builtins/evalstring.c
5288 - removed private definition of zwrite
5291 - double_quote needs to protect newlines with backslashes as well
5292 - new function, un_double_quote, to remove backslashes proctecting
5293 characters that are special in double quotes
5296 - new extern declaration for un_double_quote
5299 - changed read_token_word to requote the expanded value of $'...'
5301 - added a new flag to parse_matched_pair: P_ALLOWESC. It allows
5302 backslashes to quote embedded single quotes, and is used by
5303 the $'...' translation code for better ksh93-compatibility
5304 - changed localeexpand to call mk_msgstr on the string passed
5305 before displaying it if all we're doing is displaying translatable
5306 strings in `po' format. mk_msgstr quotes backslashes and double
5307 quotes in the string passed with backslashes, and encloses the
5308 result in double quotes. If only -D is supplied, the string is
5309 not changed at all -- this is what ksh93 does
5311 lib/readline/rlconf.h
5312 - removed PAREN_MATCHING #define, paren matching is always compiled
5315 lib/readline/parens.c
5316 - removed code that was active if PAREN_MATCHING was not defined
5317 - added _rl_enable_paren_matching, which is called when the readline
5318 variable `blink-matching-paren' is assigned a value and changes
5319 the appropriate key bindings in emacs_standard_keymap
5322 - no more PAREN_MATCHING defines, `blink-matching-paren' is always
5324 - if `blink-matching-paren' is assigned a value, call
5325 _rl_enable_paren_matching (rl_blink_matching_paren)
5327 lib/readline/emacs_keymap.c
5328 - removed PAREN_MATCHING defines; the default key bindings for
5329 ), ], and } are self-insert
5334 - added an extra argument to ansicstr so that `echo -e' will not
5338 - changed extern declaration for ansicstr
5340 parse.y, builtins/{echo,printf}.def
5341 - changed calls to ansicstr() appropriately
5344 - in parse_string_to_word_list, if an unexpected token is encountered
5345 that causes the string to not parse to a simple command, or to
5346 completely consume the string, display an error message and jump
5347 back to the top level after restoring the parsing environment,
5348 returning an error status from the attempted assignment
5353 - fixed patscan and extmatch to handle embedded [...](...) patterns
5356 tests/{extglob2.{tests,right},run-extglob2}
5357 - an additional set of ksh extended globbing tests, cribbed from zsh
5362 - changed unset_nodelay_mode slightly to make sure it handles both
5363 O_NDELAY and O_NONBLOCK if they have different values; it now
5364 returns a value of 0 on success (or no action); -1 on failure
5367 - changed extern declaration for unset_nodelay_mode
5370 lib/readline/shell.c
5371 - new function: unset_nodelay_mode; identical to definition in
5374 lib/readline/input.c
5375 - changed rl_getc to call unset_nodelay_mode if the read fails with
5376 errno == EWOULDBLOCK || errno == EAGAIN
5380 lib/termcap/termcap.c
5381 - minor changes from termutils-2.0
5382 - minor change to MS-DOS version of valid_filename_p so MS-DOS-specific
5383 code from tgetent() can be removed (from Michel@smr.nl)
5386 - in _rl_read_file, null-terminate the buffer at the number of
5387 characters actually read, not what stat() says the file size is
5388 - use ~/_inputrc as a last-ditch inputrc filename on MS-DOS
5390 lib/readline/complete.c
5391 - change printable_part to handle MS-DOS `drive-letter:' pathname
5393 - removed __GO32__ code, since it's for DJGPP 1.x, which is not
5394 supported any more, and they don't work for DJGPP 2.x
5395 - added code to support MS-DOS drive letter prefixes and //X/...
5396 to filename_completion_function
5397 - _rl_completion_case_fold defaults to 1 on MS-DOS
5399 lib/readline/{display,input,readline,rltty,signals,terminal}.c
5400 - removed __GO32__ code
5402 lib/readline/histfile.c
5403 - make read_history_range and history_truncate_file work with the
5404 actual number of characters read from the file, not the file size
5405 as reported by stat()
5407 lib/readline/readline.c
5408 - change bind_arrow_keys_internal to bind MS-DOS arrow keys to the
5409 appropriate functions if __MSDOS__ is defined
5411 lib/readline/rltty.c
5412 - make sure set_winsize is always defined, with a null body if
5413 TIOCGWINSZ is not defined
5415 lib/readline/shell.c
5416 - include <stdio.h>, since this file uses sprintf
5419 - MS-DOS does not support shared objects
5422 - change tilde_find_suffix and isolate_tilde_prefix to understand
5423 backslash as a pathname separator on MS-DOS
5427 lib/readline/{bind,readline,terminal}.c
5428 - no longer need to include <signal.h>
5430 lib/readline/terminal.c
5431 - don't need to include <setjmp.h>
5433 builtins/history.def
5434 - broke the code than handles deleting a particular history entry
5435 from the history list out into a separate function: delete_histent
5436 - added `-d offset' option to delete the history entry at position
5437 OFFSET, as displayed when the history is listed
5440 - new function, count_all_jobs(), returns the number of active jobs
5444 - extern declaration for count_all_jobs()
5447 - check for C library function ttyname()
5450 - define HAVE_TTYNAME if configure finds ttyname(3)
5453 - two new escape sequences for decode_prompt_string:
5455 \j number of active jobs in jobs list
5456 \l basename of shell's tty device name
5458 doc/{bash.1,bashref.texi}, lib/readline/doc/hsuser.texi
5459 - documented new `history -d' option
5460 - documented new \j and \l prompt string expansion sequences
5463 - new static state variable, currently_reading_init_file, set to
5464 1 while _rl_read_init_file is operating on a file
5465 - changed _rl_init_file_error to include the name and line number
5466 from the init file only if currently_reading_init_file is non-zero
5467 (this is needed since applications like bash can call
5468 rl_parse_and_bind, and error messages from those calls would be
5469 misleading if they referred to the last inputrc file read
5472 - support for a `extended command keymap', which will allow
5473 readline key sequences to be bound to unix commands using an
5474 auxiliary keymap and a special function that knows how to execute
5476 - bind_keyseq_to_unix_command supports `bind -x'
5477 - bash_execute_unix_command is the readline callback that looks in
5478 an auxiliary keymap to find the shell command to execute for a
5479 particular key sequence
5480 - new variable, no_empty_command_completion, which suppresses $PATH
5481 searching for command completion when TAB is typed on an empty
5485 - extern declaration for new function bind_keyseq_to_unix_command
5488 - added `-x' option to bind a key sequence to a shell command
5491 - added `-s' option to just print a builtin's short_doc
5494 - added new shell option, no_empty_cmd_completion', mirroring value
5495 of no_empty_command_completion
5497 doc/{bash.1,bashref.texi}
5498 - documented new `bind -x' option
5499 - documented new shopt `no_empty_cmd_completion' option
5500 - documented new `help -s' option
5503 - changed RELSTATUS to `devel'
5511 - add `-h $@' to linking options on Solaris 2 with gcc
5514 - changes to add {pre,post}-{inc,dec}rement operators (++id, --id,
5515 id++, id--). These are somewhat more liberal than ksh93, and
5516 may require more strict syntax checking down the line
5518 tests/arith.{tests,right}
5519 - additional tests for {pre,post}-{inc,dec}rement operators
5524 - structures and types for ksh-93-style arithmetic `for' command
5527 - new `--enable-arith-for-command' option to compile arithmetic for
5528 command code into the shell
5531 - new define, ARITH_FOR_COMMAND, turned on by configure
5534 - changed read_token_word to parse a set of arithmetic for expressions
5535 between (( and )) as long as the last token read before the `(('
5537 - added grammar rules to build arithmetic for commands
5540 - functions to parse (( ... )) into the three sub-expressions needed
5541 for the arithmetic for command and create the command structures
5542 (done this way instead of in the grammar rules to avoid forcing
5543 users to quote special characters between the (( and )) )
5546 - extern declaration for make_arith_for_command
5549 - code to copy arithmetic for commands
5552 - code to dispose of arithmetic for commands
5555 - code to print arithmetic for commands
5558 - code to execute arithmetic for commands and note that they are
5559 shell control structures for the piping code
5561 doc/{bash.1,bashref.texi}
5562 - documented new arithmetic for command
5565 - documented new configure --enable-arith-for-command option
5570 - added `-t timeout' option and code to support it
5574 examples/loadables/Makefile.in
5575 - various clean targets need to descend into perl
5577 examples/loadables/perl/Makefile.in
5578 - added mostlyclean and maintainer-clean targets
5581 - new directory, with files from lib/posixheaders
5586 {posixwait,unionwait,maxpath}.h
5587 - moved from top src directory to include subdir
5589 Makefile.in,builtins/Makefile.in,lib/{glob,malloc,sh,tilde}/Makefile.in
5590 - updated dependencies and file lists for new include directory
5591 - added BASHINCDIR variable, added -I${BASHINCDIR} to cc's include path
5593 MANIFEST,support/SYMLINKS
5594 - updated for new include directory
5596 lib/readline/{ansi_stdlib,posixdir,posixjmp,posixstat,rlstdc}.h
5597 - changed symlinks to point to ../../include rather than
5601 - changed `#include "../stdc.h"' to `#include "stdc.h"'
5603 builtins/{cd,exec,fc,history,pushd,source,type,umask,printf}.def
5604 builtins/{mkbuiltins,common,evalfile,evalstring,getopt}.c
5605 - changed include specifications:
5606 ../posixstat.h -> posixstat.h
5607 ../filecntl.h -> filecntl.h
5608 ../maxpath.h -> maxpath.h
5609 ../memalloc.h -> memalloc.h
5612 - new file, contents of bashtty.h and code from jobs.c that includes
5613 the appropriate terminal file
5616 - new file with some tty manipulation utility functions
5622 - include shtty.h instead of bashty.h and other code that includes
5623 the correct system-dependent tty include file
5626 - added shtty.o as part of libsh.a
5629 - added include/shtty.h and lib/sh/shtty.c, removed bashtty.h
5633 lib/readline/display.c
5634 - some more __MSDOS__ code to make readline work better with DJGPP:
5635 output \r instead of tputs(term_cr, ...)
5637 lib/readline/terminal.c
5638 - some changes for __DJGPP__ (one is of dubious value -- doesn't
5639 DJGPP have a termcap library?)
5644 - make sure that the $CC argument to shobj-conf is quoted
5647 - changes to SGI SHOBJ_LDFLAGS from David Kaelbling <drk@sgi.com>
5652 - interface to read(2) that restarts automatically if errno == EINTR
5655 - new declarations for functions in lib/sh/{zread,zwrite}.c
5657 lib/sh/Makefile.in, Makefile.in
5658 - add zread.c, zread.o to appropriate file lists
5660 {subst,input}.c, builtins/{evalstring.c,read.def}
5661 - converted some loops around read() to call zread() instead
5663 lib/readline/rltty.h
5664 - new struct _rl_tty_chars to save tty special characters
5666 lib/readline/rltty.c
5667 - new function save_tty_chars to save tty special characters
5668 (currently they're only saved -- nothing looks at them yet)
5669 - two new internal library functions, _rl_disable_tty_signals ()
5670 and _rl_restore_tty_signals (), intended to disable tty driver
5671 signal processing for readline's literal-next code, so users
5672 can do stuff like ^V^C and have ^C end up in the readline
5673 buffer even if ^C is the terminal's interrupt character
5675 lib/readline/readline.c
5676 - changed rl_quoted_insert to disable and restore tty signal
5677 handling around the call to rl_read_key (), so users can put
5678 tty special chars into the readline buffer
5683 - added `,' operator (expr1 , expr2) -- both expr1 and expr2 are
5684 evaluated and the return value is the value of expr2. Precedence
5685 is higher than assignment (which makes it highest)
5686 - make `lasttp' (pointer to last token) part of the expression
5687 context that is saved and restored by {push,pop}_context. This
5688 is used only in error reporting
5690 doc/{bash.1,bashref.texi}
5691 - documented new `,' arithmetic operator
5692 - cleaned up some of the language concerning variables referenced
5693 by name within an arithmetic expression
5695 lib/readline/readline.c
5696 - new application-settable variable, rl_num_chars_to_read, which, if
5697 set to a non-zero value, causes readline to return after reading
5698 that many characters (or at least that many characters, if
5699 rl_startup_hook is used to prime the input buffer) rather than
5700 when reading a character bound to accept-line
5702 lib/readline/readline.h
5703 - extern declaration for rl_num_chars_to_read
5706 - added new `-n nchars' option to read NCHARS from stdin rather than
5707 a complete line. Works both with and without using readline
5709 doc/{bash.1,builtins.texi}
5710 - documented new `read -n nchars' option
5715 - make sure all uses of PIDs are of type pid_t
5718 - broke stdin_redirects into two functions: stdin_redirection, which
5719 checks a single redirection specification, and a new stdin_redirects,
5720 which does what it did before but calls stdin_redirection for each
5721 redirection in the chain
5726 - new test, BASH_CHECK_DEV_STDIN, checks for /dev/stdin. If it's
5727 present HAVE_DEV_STDIN is defined and it's assumed that /dev/stdout
5728 and /dev/stderr are present as well
5731 - call BASH_CHECK_DEV_STDIN
5734 - add HAVE_DEV_STDIN, initially undefined
5737 - add /dev/std{in,out,err} to the special filenames that are handled
5738 by test_stat() if HAVE_DEV_STDIN is not defined
5740 doc/{bash.1,bashref.texi}
5741 - documented conditional expressions' handling of /dev/std{in,out,err}
5744 - new function, find_string_in_alist, to find (or match as an extended
5745 glob pattern) a string in a STRING_INT_ALIST and return the
5746 associated token value
5749 - extern declaration for find_string_in_alist
5752 - new STRING_INT_ALIST list of filenames the redirection code handles
5753 specially (_redir_special_filenames)
5754 - new function, redir_special_open () to handle filenames found in
5755 _redir_special_filenames (framework for /dev/tcp and /dev/udp, but
5756 those are not implemented get)
5758 doc/{bash.1,bashref.texi}
5759 - documented special filename handling in redirections
5764 - added `-d delim' option, like ksh93, to read until delim rather
5767 doc/{bash.1,bashref.texi}
5768 - documented new read `-d delim' option
5771 - look for gethostbyname(3), inet_aton(3)
5772 - look for <netdb.h> and <netinet/in.h>
5773 - call BASH_FUNC_GETHOSTBYNAME if gethostbyname(3) is not in libc
5774 - check for u_int and u_long types, default to `unsigned int' and
5775 `unsigned long' respectively
5776 - new enable option `--enable-net-redirections' to compile in the
5777 /dev/tcp and /dev/udp redirection code
5780 - new macro, BASH_FUNC_GETHOSTBYNAME, looks for gethostbyname(3) in
5781 the socket libraries if it's not found in libc
5784 - new defines: HAVE_GETHOSTBYNAME, HAVE_INET_ATON, HAVE_NETDB_H,
5785 HAVE_NETINET_IN_H, NETWORK_REDIRECTIONS
5786 - new defines: u_int, u_long
5789 - new file, from GNU libc, slightly modified to remove inet_addr()
5792 - new file, functions to create tcp/udp network connections. Exports
5793 a single function: netopen(pathname)
5796 - extern declaration for netopen()
5798 lib/sh/Makefile.in, Makefile.in, MANIFEST
5799 - added appropriate references to inet_aton.c and netopen.c
5802 - if HAVE_SYS_SOCKET_H, HAVE_GETPEERNAME, and HAVE_NETINET_IN_H are
5803 all defined, define HAVE_NETWORK
5806 - call netopen for pathnames of the form /dev/(tcp|udp)/host/port
5807 if HAVE_NETWORK is defined; print a warning message otherwise
5808 - /dev/tcp and /dev/udp code is only compiled in if
5809 NETWORK_REDIRECTIONS is defined
5814 - new function, zsyncfd(fd) which syncs the kernel's seek pointer on
5815 FD with the last character returned by zreadc()
5818 - extern declaration for zsyncfd
5821 - use zreadc if the input is not unbuffered (this cuts the number
5822 of read(2) calls *way* down)
5823 - if input is not unbuffered, call zsyncfd before returning to make
5824 sure zreadc's buffering doesn't consume too much input
5829 - install bashbug with mode 555
5834 - make want_pending_command and read_from_stdin global rather than
5838 - change which_set_flags to insert `c' and `s' if the `-c' and `-s'
5839 invocation options, respectively, were supplied at shell startup
5842 - change bash_directory_completion_hook to change the logic for
5843 deciding whether or not to parameter expand the directory name --
5844 now we expand only if there's a `$' (still has problems if the
5845 user quoted the `$') or a `` pair. Fixes bug reported by
5846 chuckjr@sinclair.net. To fix the `$' problem, could possibly
5847 check what the user typed with rl_line_buffer and start, end
5848 parameters to gen_completion_matches
5849 - changed attempt_shell_completion to slightly adjust the logic for
5850 deciding whether or not a word is in a command position: if the
5851 word being completed has a single opening single or double quote
5852 before the command separator, treat it as a candidate for (quoted)
5853 command word completion
5854 - now that we understand partially-quoted strings as completion
5855 candidates, we can do command completion on certain unclosed
5859 - change extract_delimited_string to not return an error for an
5860 unclosed construct if DOING_COMPLETION is non-zero
5865 - fixed `ss=09 ; let ss=10' bug by introducing one-token lookahead
5866 after a string token is parsed. If the next token is `=', we
5867 don't evaluate the variable's value as an expression, since it's
5868 not going to be used
5871 - added new member to struct variable: exportstr -- for the future
5872 caching of strings to be placed into the environment
5873 - extern declaration for bind_variable_value
5876 - make sure that the `exportstr' member of a struct variable is
5877 initialized correctly, and put code in to free it where appropriate
5879 - new function, bind_variable_value(VAR, VALUE); make shell variable
5880 VAR have value VALUE
5881 - make sure var->exportstr is invalidated when a variable or function
5884 builtins/declare.def
5885 - call bind_variable_value instead of duplicating some of bind_variable
5891 - new macros, VSETATTR and VUNSETATTR to set and clear variable
5894 builtins{read,set,setattr,declare}.def,{execute_cmd,expr,shell,subst,variables}.c
5895 - change to use VSETATTR and VUNSETATTR
5900 - if htmldir is set by configure, install the html files into that
5901 directory with `make install' and remove them with `make uninstall'
5903 Makefile.in,doc/Makefile.in
5904 - htmldir is set by configure and passed from the Makefile to the
5905 install in the doc subdirectory
5908 - substitute `htmldir' into Makefiles
5910 support/config.guess
5911 - some small changes for Apple's Rhapsody
5913 lib/termcap/Makefile.in
5914 - make the `distclean' and `maintainer-clean' targets remove Makefile
5917 - new private library include file, for Rhapsody __private_extern__
5920 lib/termcap/{termcap,tparam}.c
5922 - if HAVE_CONFIG_H is defined, include <stdlib.h> if HAVE_STDLIB_H is
5923 defined, otherwise declare getenv, malloc, realloc as extern
5924 - add __private_extern__ qualifier for extern data that Rhapsody
5928 - don't run the startup files in the rshd case if shell_level is >= 2
5929 This should catch the case of
5930 rsh machine bash -c 'echo a'
5931 running the .bashrc twice, once for the shell started by rshd and
5932 one for the shell running -c command
5937 - in initialize_shell_variables, unset the export attribute from
5938 SSH_CLIENT if it exists and we got it from the initial environment
5941 - don't bother unsetting export attribute from SSH_CLIENT, since we
5942 now do it in initialize_shell_variables
5944 lib/readline/display.c
5945 - don't check prompt_this_line[-2] in rl_redisplay if prompt_this_line
5946 isn't at least 2 characters after the start of rl_display_prompt
5948 lib/readline/histfile.c
5949 - change the name of the default history file to _history on MS-DOS
5951 lib/readline/histlib.h
5952 - add an extern declaration for history_offset
5954 lib/readline/hist{expand,search}.c
5955 - remove extern declaration for history_offset; now in histlib.h
5957 lib/readline/xmalloc.h
5958 - new file, extern declarations for xmalloc, xrealloc, xfree
5960 lib/readline/rlprivate.h
5961 - new file, with extern declarations for `readline private' global
5962 variables and functions
5964 lib/readline/rlshell.h
5965 - new file, with extern function declarations for stuff in shell.c
5967 lib/readline/Makefile.in
5968 - add dependencies on xmalloc.h, rlshell.h
5969 - add xmalloc.h, rlprivate.h to list of header files
5972 - add lib/readline/xmalloc.h, lib/readline/rlprivate.h,
5973 lib/readline/rlshell.h
5976 - add $(RL_LIBSRC)/xmalloc, $(RL_LIBSRC)/rlprivate.h,
5977 $(RL_LIBSRC)/rlshell.h to READLINE_SOURCE variable
5979 lib/readline/{bind,complete,display,funmap,histexpand,histfile,history,input,
5980 isearch,keymaps,kill,macro,readline,search,shell,util,vi_mode}.c
5981 - include "xmalloc.h" rather than extern declarations for xmalloc,
5984 lib/readline/terminal.c
5985 - new function, used in two places, _emx_get_screensize for EMX
5987 lib/readline/readline.c
5988 - EMX apparently no longer needs _emx_build_environ
5990 lib/readline/signals.c
5991 - support for __EMX__ in rl_signal_handler
5992 - don't set the old handler passed to rl_set_sighandler to
5993 rl_signal_handler, because that would cause infinite recursion if
5994 that signal were generated
5996 lib/readline/xmalloc.c
5997 - no longer the same as lib/malloc/xmalloc.c, which is no longer
5999 - changes to include xmalloc.h, define READLINE_LIBRARY, change
6000 some of the argument types
6003 - add prototypes for extern function declarations if __STDC__
6006 lib/readline/{terminal,bind,readline,nls,histexpand}.c
6007 - include "rlshell.h" for function prototypes
6011 lib/readline/{bind,callback,complete,display,input,isearch,kill,macro,nls,
6012 parens,readline,rltty,search,signals,terminal,util,vi_mode}.c
6013 - include "rlprivate.h"
6014 - remove extern declarations already in rlprivate.h
6017 - xfree should take a PTR_T as its argument
6020 - change prototype for xfree to use void * instead of char *
6023 - define PTR_T like it is defined in general.h
6024 - malloc() returns a PTR_T
6025 - free() takes a PTR_T as its argument
6026 - realloc() returns a PTR_T and takes a PTR_T as its first argument
6027 - memalign returns a PTR_T
6028 - valloc returns a PTR_T
6029 - calloc returns a PTR_T
6030 - cfree() takes a PTR_T
6033 - new function: char **all_variables_matching_prefix (char *prefix)
6036 - extern declaration for all_variables_matching_prefix
6039 - converted variable_completion_function to use
6040 all_variables_matching_prefix
6043 - new function, char **alloc_array(n), allocates an argv-style
6044 array of strings with room for N members
6047 - extern declaration for alloc_array
6051 lib/readline/keymaps.c
6052 - include "readline.h"
6053 - remove extern function declarations
6056 - break the definition of __P out from a strict __STDC__ block,
6057 since __GNUC__ and __cplusplus also indicate that prototypes
6060 lib/readline/readline.h
6061 - adjust conditional declaration of rl_message, since __cplusplus
6062 indicates that prototypes are available
6064 lib/readline/rlstdc.h
6065 - private copy, modified, no longer symlinked to ../../include/stdc.h
6066 - __P is defined if __GNUC__ or __cplusplus is defined
6067 - removed defines for __STRING, const, inline, signed, volatile, since
6068 readline does not use them
6070 lib/readline/{search,readline}.c
6071 - extern declaration for _rl_free_history_entry with prototypes,
6072 since it's not in rlprivate.h
6074 lib/readline/history.h
6075 - added some missing `extern's in function declarations
6078 - include "rlprivate.h"
6080 lib/readline/shell.c
6081 - include "rlshell.h"
6083 lib/readline/Makefile.in
6084 - update dependencies for undo.c, shell.c
6087 - add #define for __P if not already defined
6088 - use prototypes in extern function declarations with __P()
6090 lib/readline/doc/rluserman.texinfo
6091 - new file, derived from rlman.texinfo
6093 {bashline,findcmd,general,pathexp}.c, builtins/getopts.def
6094 - call alloc_array(N) instead of (char **)xmalloc (N * sizeof (char *))
6097 - added code to implement ksh-93 ${!prefix*} expansion
6099 doc/{bash.1,bashref.texi}
6100 - documented new ${!prefix*} expansion
6105 - new variable, this_shell_function, points to SHELL_VAR of currently
6106 executing shell function
6109 - new dynamic variable, FUNCNAME -- invisible when not executing shell
6112 doc/{bash.1,bashref.texi}
6113 - documented new FUNCNAME variable
6118 - add -T option to specify correct termcap library
6121 - Irix 4.x still needs to link with -lsun if it contains a replacement
6122 getpwent function that works with NIS
6123 - if we're configuring with an already-installed readline library,
6124 call BASH_CHECK_LIB_TERMCAP and pass the resulting $TERMCAP_LIB to
6127 lib/readline/readline.c
6128 - in rl_forward, if rl_point ends up being < 0, set it to 0
6130 lib/readline/exammples/excallback.c
6131 - new callback example code, from `Jeff Solomon <jsolomon@stanford.edu>'
6134 - define NULL as 0 if not defined by one of the standard include files
6135 - cast result of malloc and realloc to (char *) where appropriate
6138 - new functions for use by dynamic variables: null_assign and
6139 null_array_assign. Used as assign_func for a particular variable,
6140 they cause assignments to that variable to be silently ignored
6141 - FUNCNAME and GROUPS are no longer readonly
6142 - FUNCNAME changed to use null_assign
6143 - GROUPS changed to use null_array_assign. This means that the
6144 variable can be unset if desired (like for Oracle startup scripts),
6145 but cannot be assigned to
6147 doc/{bash.1,bashref.texi}
6148 - added text about assignments being silently discarded to descriptions
6149 of FUNCNAME and GROUPS
6150 - removed text saying that GROUPS is readonly
6151 - added standard text about GROUPS being unset and losing its special
6152 properties, even if reset
6155 - new command type, cm_subshell, actually causes the shell to fork
6156 and then executes the command in the SUBSHELL_COM struct
6159 - ( ... ) now creates a command of type cm_subshell, with the same
6160 flag CMD_WANT_SUBSHELL as previous
6163 - new function make_subshell_command
6166 - extern declaration for make_subshell_command
6169 - code to destroy a SUBSHELL_COM
6172 - code to duplicate a SUBSHELL_COM
6175 - code to print a SUBSHELL_COM
6178 - broke the code that handles executing commands in subshells out of
6179 execute_command_internal into a new function, execute_in_subshell,
6180 with the same arguments
6181 - executing a command of type cm_subshell is just a slightly special
6182 case, handled in execute_in_subshell
6187 - changed code in execute_command_internal that executes subshell
6188 commands to check for command->type == cm_subshell in addition to
6189 checking that commmand->flags & CMD_WANT_SUBSHELL is non-zero
6190 - changed execute_in_subshell to set the CMD_NO_FORK flag on the
6191 command to be executed by a command of type cm_subshell
6192 (command->value.Subshell->command), if that command is a simple
6193 command (type == cm_simple) or a nested subshell (type == cm_subshell)
6194 and is not being timed
6195 - changed execute_command_internal to just call and return the value
6196 returned by execute_in_subshell if it gets a command of type
6197 cm_subshell with flags including CMD_NO_FORK
6200 - morecore() should always return through morecore_done, not with a
6206 - new function, quote_array_assignment_chars, backslash quotes all
6207 `[' and `]' before an `=' in a word that's part of the body of a
6208 compound array assignment. Needed because we run the list through
6209 the globbing code now. Don't bother if `=' does not appear in
6210 the string or if the first char is not `['
6211 - call quote_array_assignment_chars from assign_array_var_from_string
6215 - moved parse_string_to_word_list to parse.y
6218 - moved parse_string_to_word_list here. Much simpler -- no longer
6219 tries to parse a command, but just reads tokens using read_token().
6220 Any token but a WORD or ASSIGNMENT_WORD causes a syntax error.
6221 Don't have to mess around with saving global_command or calling
6222 parse_command, but do need to save and restore the history stuff,
6223 so the array assignment doesn't get saved on the history list
6228 - changed to use functions in lib/sh/shtty.c (tt{get,set}attr) for
6229 the terminal attributes
6230 - added a `flags' field to struct proc_status, flags are PROC_RUNNING
6231 and PROC_NOTIFIED (status has been returned to `wait')
6232 - functions check flags & PROC_RUNNING to check whether or not a
6233 particular process is still alive; PROC_RUNNING is reset by
6235 - new function, mark_dead_jobs_as_notified, same function as the one
6237 - cleanup_dead_jobs reaps jobs only if they're dead and not marked
6239 - wait_for_background pids marks all pids as notified and reaps them
6240 before it returns, since it's called by the `wait' builtin
6241 - wait_for_single_pid marks the pid being waited for as notified so
6242 its slot can be reclaimed -- it's only called by the `wait' builtin
6243 - new function, process_exit_status, to turn what wait(2) takes into
6249 - add_pid takes a new second argument, async_p, which is non-zero if
6250 the process is in the background
6251 - new flag, PROC_ASYNC, set by add_pid
6252 - set_pid_status now sets the PROC_NOTIFIED flag if PROC_ASYNC is unset,
6253 so foreground jobs get cleaned up right away
6254 - changed mark_dead_jobs_as_notified to take a `force' argument; if
6255 non-zero, it marks only enough dead jobs to make the number of
6256 un-notified dead jobs < CHILD_MAX
6257 - new function, reap_dead_jobs, same as in jobs.c
6260 - don't need separate cases for REAP any more
6265 - new function, tescape, which processes a single backslash
6266 escape sequence and returns the number of characters consumed by
6267 the argument string (code taken from bexpand)
6268 - changed bexpand to call tescape rather than do backslash-escape
6269 sequence conversion itself
6270 - changed occurrences of `illegal' in error messages to `invalid'
6271 - printf no longer calls ansicstr to translate backslash-escape
6272 sequences; the mainline printf code now calls tescape whenever it
6278 - new variable, garglist, set to list of words to be expanded after
6279 leading assignment statements are removed
6280 - command_substitute now calls maybe_make_exported_env before making
6281 the child process if there are no variable assignments preceding
6282 the command currently being expanded, or if the command currently
6283 being expanded consists only of variable assignments
6286 - the `early fork' code in execute_simple_command now calls
6287 maybe_make_export_env before forking because execute_disk_command
6288 would do that in the vast majority of cases, and this will obviate
6289 the need to do it for subsequent commands if the environment does
6295 - more macros to manipulate the exportstr member of a SHELL_VAR
6296 - changed initialize_shell_variables to cache the value from the
6297 environment as the initial exportstr for all imported variables
6298 - changed make_var_array to use exportstr if it exists, instead
6299 of computing the value
6300 - changed make_var_array to cache exportstr for exported functions,
6301 so they don't have to be deparsed every time the export env is
6306 lib/readline/{histlib,rldefs}.h
6307 - changed STREQN macro to evaluate to 1 if the third argument is 0
6309 lib/readline/search.c
6310 - changed rl_history_search_{for,back}ward so they leave point at
6311 the end of the line when the string to search for is empty, like
6312 previous-history and next-history
6313 - broke common code out of rl_history_search_{for,back}ward into
6314 a new function, rl_history_search_reinit
6315 - rewrote rl_history_search_internal to be more like the
6316 non-incremental search functions, use noninc_search_from_pos,
6317 and leave the last history line found in the current line buffer
6319 - new function, make_history_line_current, takes care of making
6320 the current line buffer a copy of the history entry passed as an
6321 argument; used by rl_history_search_internal and noninc_dosearch
6324 - make ${!prefix@} be the same as ${!prefix*} for (undocumented)
6329 lib/readline/doc/rltech.texinfo
6330 - added note about including <readline/readline.h>, and that <stdio.h>
6331 should be included before readline.h
6333 lib/readline/doc/hstech.texinfo
6334 - added note about including <readline/history.h>
6336 lib/readline/doc/manvers.texinfo
6337 - updated version to 4.1
6339 lib/readline/{bind,complete,display,isearch,nls,parens,readline,signals,tilde,
6341 - added prototypes with __P((...)) for forward static function
6344 lib/readline/display.c
6345 - broke the code that initializes VISIBLE_LINE and INVISIBLE_LINE out
6346 of rl_redisplay into a new function, init_line_structures, which
6347 takes an argument giving the minimum number of characters that the
6349 - new function for use by applications that want to display the
6350 initial prompt themselves rather than having the first call to
6351 readline do it: rl_on_new_line_with_prompt (modified from code in
6352 the CLISP distribution)
6354 lib/readline/readline.c
6355 - new external variable, rl_already_prompted, to let readline know
6356 that the prompt string has already been displayed on the screen
6357 before the first call to readline
6358 - test rl_already_prompted before displaying the prompt in
6359 readline_internal_setup
6360 - if rl_already_prompted is non-zero, readline_internal_setup calls
6361 rl_on_new_line_with_prompt instead of rl_on_new_line
6363 lib/readline/readline.h
6364 - extern declaration for rl_on_new_line_with_prompt
6365 - extern declaration for rl_already_prompted
6367 lib/readline/doc/rltech.texinfo
6368 - documented rl_on_new_line_with_prompt and rl_already_prompted
6371 - new -s option (silent mode). Input from a terminal is not echoed
6373 doc/{bash.1,bashref.texi}
6374 - documented new `-s' option to read builtin
6378 lib/readline/vi_mode.c
6379 - replaced references to rl_getc with (*rl_getc_function)
6381 [bash-2.04-devel frozen]
6386 - make sure that verify_substring_values always passes malloc'd
6387 memory to maybe_expand_string as the string to be expanded,
6388 since it gets freed on errors
6391 - don't need -R option for shared libraries on Solaris
6392 - new stanza for OSF/1 machines with gcc
6394 lib/readline/readline.c
6395 - new variable, rl_gnu_readline_p, always 1. Available to allow
6396 readline users to test whether or not they're linking against
6397 the true readline, rather than some bogus replacement (from CLISP)
6399 lib/readline/readline.h
6400 - extern declaration for rl_gnu_readline_p
6402 hashlib.h, hashcmd.h
6403 - added prototypes to extern function declarations
6406 - new file, declarations for the programmable completion stuff
6409 - new file, library functions for programmable completion
6413 builtins/complete.def
6414 - new file, interface to programmable completion management

6425 #undef PROGRAMMABLE_COMPLETION
6428 - new file, placeholder for programmable completion generators and
6429 associated functions
6431 Makefile.in, builtins/Makefile.in
6432 - changes to add pcomplete.c, builtins/complete.def
6437 - new function, #ifdef READLINE, skip_to_delim (s, i, delims).
6438 Starting at s[i], return the index of the first character in s
6439 that is contained in delims. Understands shell quoting.
6440 - added two arguments to list_string_with_quotes: an index to
6441 watch for, and a pointer to int to return the index into the
6442 created word list of the word containing the sentinel. Now
6443 compiled in all the time. The returned index starts at 1.
6446 - extern declarations for char_is_quoted, unclosed_pair, and
6448 - changed extern declaration for list_string_with_quotes, moved
6449 it out of the #ifdef ARRAY_VARS section
6452 - removed extern declarations for char_is_quoted and unclosed_pair
6455 - new function, SHELL_VAR **all_exported_variables()
6456 = new function, SHELL_VAR **all_array_variables(), #ifdef ARRAY_VARS
6459 - extern declaration for all_exported_variables, all_array_variables
6462 - replacement if we don't have strpbrk(3)
6464 configure.in, config.h.in

6487 converts an array to a list of string values
6490 - extern declaration for array_to_argv
6493 - new convenience function, int execute_shell_function (SHELL_VAR *,
6497 - extern declaration for execute_shell_function
6499 builtins/evalstring.c
6500 - make parse_and_execute unwind_protect current_prompt_string
6501 if the shell is interactive
6506 - moved bind_int_variable from expr.c to here; it now returns a
6507 SHELL_VAR *, like the other variable binding functions
6510 - extern declaration for bind_int_variable
6514 bashline.c, parse.y, general.c, make_cmd.c, subst.c, braces.c, execute_cmd.c
6515 - replaced some common code sequences with calls to substring()
6517 lib/readline/doc/rltech.texinfo
6518 - fixed small typo in description of rl_completion_entry_function
6523 - new function, strcreplace(char *string, int c, char *text, int do_glob)
6524 replaces all occurrences of C in STRING with TEXT. Backslash may
6525 be used to quote C. If DO_GLOB is non-zero, the replacement TEXT
6526 is quoted to protect globbing characters.
6529 - extern declaration for strcreplace
6532 - use strcreplace in expand_histignore_pattern
6535 - finished initial implementation of programmable completion
6538 - code to set the aliases itemlist to dirty when an alias is added
6539 or removed, if PROGRAMMABLE_COMPLETION is defined
6542 - code to set the functions itemlist to dirty when a shell function
6543 is added or removed, if PROGRAMMABLE_COMPLETION is defined
6546 - code to set the builtins itemlist to dirty when a shell builtin
6547 is added or removed, if PROGRAMMABLE_COMPLETION is defined
6548 - code to set the enabled and disabled itemlists to dirty when a
6549 builtin is enabled or disabled, if PROGRAMMABLE_COMPLETION is
6553 - new shell option, `progcomp', on if programmable_completion_enabled
6554 (from pcomplete.c) is non-zero
6556 doc/{bash.1,bashref.texi}
6557 - note that `${' is not eligible for brace expansion to avoid
6558 conflicts with parameter expansion
6562 builtins/complete.def
6563 - added a new `compgen' builtin for use by completion functions
6568 - new function, void clear_hostname_list(void), to delete all the
6569 entries in the hostname completion list
6572 - extern declaration for clear_hostname_list
6575 - changed sv_hostfile to clear the hostname list if $HOSTFILE is
6578 doc/{bash.1,bashref.texi}
6579 - documented new behavior of HOSTFILE when it's unset
6580 - added some awkwardly-worded text to make it clear that an
6581 interactive shell cannot be started with non-option arguments
6582 or with the -c option
6585 - restored NON_INTERACTIVE_LOGIN_SHELLS test, so that if it is
6586 defined, shells with argv[0][0] == '-' and not in posix mode
6587 run the startup files even if non-interactive
6590 - added commented-out #define for NON_INTERACTIVE_LOGIN_SHELLS
6595 - make sure the characters in IFS are cast to unsigned before being
6596 indexed in ifscmap (expand_word_internal)
6601 - change grammar rule for arithmetic for expressions to handle a
6602 list_terminator after the `))' instead of requiring a newline_list
6605 - fix so that variable indirection can reference the shell's special
6606 variables (like $0...$9, $$, $#, etc.)
6609 - changed gen_wordlist_matches to use split_at_delims to split the
6610 string at $IFS first, then expand each individual word
6614 lib/readline/histfile.c
6615 - change things so that O_BINARY mode is used when reading and writing
6616 the history file on cygwin32 as well as OS/2 (__EMX__)
6619 - add calls to push_delimiter and pop_delimiter around the call
6620 to parse_matched_pair when parsing $'...' and $"..." so the
6621 history entry is added correctly
6625 doc/{bash.1,bashref.texi}, lib/readline/doc/rluser.texinfo
6626 - documented new programmable completion facilities
6629 - documented new configure `--enable-progcomp' option
6634 - if make_local_variable is being asked to make a local shadow
6635 variable of a read-only variable, print an error message and
6637 - if make_local_variable returns NULL to make_local_array_variable,
6640 builtins/declare.def
6641 - if we're making local variables, and make_local_array_variable or
6642 make_local_variable returns NULL, just flag an error and go on
6647 - changed release status to `alpha1'
6649 [bash-2.04-alpha1 frozen]
6654 - fixed find_cmd_start so that it doesn't spin-loop on commands with
6655 a command separator like `;' or `&'. Problem was not incrementing
6656 `os' past the delimiter found
6661 - cosmetic change: introduced two macros to encapsulate initialization
6662 of dynamic variables
6667 - new function: num_progcomps(void), returns the number of entries in
6668 the programmable completions hash table
6671 - extern declaration for num_progcomps
6674 - make sure some programmable completions have been defined before
6675 diving into the programmable completion code
6678 - in open_shell_script, move the fd opened to the script to a high
6679 one with move_to_high_fd in all cases -- the buffered input code
6680 still has problems if fd == 0 and later on fd 0 is closed or
6681 redirected (cf. input.c:check_bash_input())
6684 - getlong() now calls strtol directly with a third argument of 0 so
6685 it can handle 0x (hex) and 0 (octal) prefixes, which legal_number
6686 does not -- this has implications for arguments to %d that begin
6690 - make sure that the variable found in the temporary environment has
6691 a non-null value before calling savestring() on it
6694 - make sure split_at_delims returns 0 in *nwp and *cwp if handed a
6695 null or empty string
6698 - make sure build_arg_list handles lwords == 0, as it will be if an
6699 empty command line is handed to the programmable completion code
6700 (like compgen -C xyz)
6703 - make sure execute_shell_function passes a non-null bitmap of fds to
6704 close to execute_function, allocating and deallocating it locally
6707 - don't mess with SIGPROF in initialize_terminating_signals
6710 - if the user has requested it with checkwinsize, check for a new
6711 window size after a job exits due to a signal as well as being
6715 - changed rl_kill_region to set the point to the beginning of the
6716 region after the kill is performed
6721 - make sure ranges ([1-9]*) are protected with [...] for m4 quoting
6724 - make sure that bind_variable_value honors `set -a' and that it
6725 marks the environment for recreation if necessary
6729 lib/readline/complete.c
6730 - if we're completing at the end of the line, find_completion_word
6731 shouldn't test whether the character is a special word break
6732 char and (possibly) advance rl_point past the end of the buffer
6735 - change mk_msgstr to write embedded newlines as `\n"<NL>"', as the
6736 PO file format apparently requires
6740 lib/readline/display.c
6741 - code to manage the growth of the inv_lbreaks and vis_lbreaks arrays
6742 beyond 256, since there are pathalogical command lines that can
6743 have more than 256 line breaks for redisplay
6748 - include pathexp.h for extern declaration of quote_globbing_chars
6751 - change CACHE_EXPORTSTR to savestring() the value and not set the
6757 - bashbug now accepts --help and --version options
6760 - change bash_quote_filename to use single quotes if the user
6761 does not specify an opening quote character and the filename being
6762 completed contains newlines
6766 configure.in, aclocal.m4, config.h.in
6767 - BASH_TYPE_INT32_T --> BASH_TYPE_BITS32_T; int32_t --> bits32_t
6768 - BASH_TYPE_U_INT32_T --> BASH_TYPE_U_BITS32_T; u_int32_t --> u_bits32_t
6770 lib/malloc/{malloc,gmalloc}.c, lib/sh/inet_aton.c
6771 - int32_t --> bits32_t; u_int32_t --> u_bits32_t
6774 - new tests: BASH_TYPE_BITS16_T, BASH_TYPE_U_BITS16_T
6777 - add check for sizeof short, sizeof char
6778 - call BASH_TYPE_BITS16_T, BASH_TYPE_U_BITS16_T
6781 - new #defines for bits16_t, u_bits16_t
6784 - use u_bits16_t for type of mi_magic2
6789 lib/readline/display.c
6790 - new private library function, _rl_strip_prompt, to remove instances
6791 of RL_PROMPT_{START,END}_IGNORE from the passed prompt string
6793 lib/readline/rlprivate.h
6794 - extern declaration for _rl_strip_prompt
6796 lib/readline/readline.c
6797 - call _rl_strip_prompt before outputting the prompt if we're not
6798 doing any echoing of input chars (readline_echoing_p == 0)
6801 - tentative change to rule for parser-built: use $< instead of
6806 support/config.{guess,sub}
6807 - add code to handle all versions of Mac OS (e.g., Mac OS X)
6812 - on cygwin32, treat \r\n as a line terminator when reading the
6818 - fixed problem in _getaddr with copying the address returned from
6819 gethostbyname to the `struct in_addr *' argument -- hostnames
6820 now work in /dev/(tcp|udp)/host/port
6825 - on Apple Rhapsody systems, set LOCAL_CFLAGS to -DRHAPSODY
6828 - changes from Apple for building fat binaries on Rhapsody,
6829 setting HOSTYPE, OSTYPE, VENDOR, and MACHTYPE
6831 lib/readline/terminal.c
6832 - some work on the `dumb terminal' setup code in _rl_init_terminal_io
6833 to make sure it's complete for use by the redisplay code and some
6834 stuff in {readline,complete}.c
6836 lib/readline/display.c
6837 - new function, _rl_current_display_line, returns the number of
6838 lines down from the first `screen line' of the current readline
6841 lib/readline/readline.c
6842 - make rl_refresh_line call _rl_current_display_line
6844 lib/readline/rlprivate.h
6845 - extern declaration for _rl_current_display_line
6850 - reorganized slightly:
6851 o a new shell builtins chapter
6852 o a new shell variables chapter
6853 o a new special builtins section
6854 o bourne shell features chapter removed
6855 o alias builtins moved to the bash builtins section
6856 o bourne shell differences moved to appendix
6857 o order of readline and history chapters swapped
6858 o indices are now unnumbered appendices
6859 o some text cleaned up and some explanatory text added
6861 lib/readline/terminal.c
6862 - if a calling application is using a custom redisplay function,
6863 don't call tgetent to get the terminal attributes, since those
6864 are used only by the redisplay code. Still get the window
6868 - range comparisons in bracket expressions no longer use strcoll(3),
6869 since in some locales (de, for example), [A-Z] matches all
6872 parse.y, print_cmd.c
6873 - some changes to make sure the shell compiles when
6874 DPAREN_ARITHMETIC is not defined but ARITH_FOR_COMMAND is
6879 - in the here document code in do_redirection_internal, check
6880 that the file descriptor returned by here_document_to_fd is not
6881 the same as a file descriptor specified as the redirector
6887 - make sure the pipline rule for `timespec BANG pipeline' sets the
6888 CMD_INVERT_RETURN flag for the pipeline command
6891 - use setjmp with a special jump buffer to take longjmps in the
6892 case that a SIGINT is received while waiting for jobs or processes
6893 it makes wait return with a status > 128, as POSIX.2 specifies
6896 - changed wait_sigint_handler to longjmp to wait_intr_buf if it's
6897 executing the wait builtin and SIGINT is trapped. It calls
6898 trap_handler to make sure a pending trap for SIGINT is set also,
6899 so the trap is taken when the wait builtin returns
6904 - save and restore the value of errno in sigchld_handler
6907 - save and restore the value of errno in trap_handler
6912 - changed release status to beta1
6917 - new file to encapsulate the <time.h> and <sys/time.h> mess
6920 - add posixtime.h to list of include files in BASHINCFILES
6921 - update dependencies for general.o, execute_cmd.o
6923 general.c, execute_cmd.c, builtins/times.def
6924 - include posixtime.h instead of <time.h>, <sys/time.h>
6927 - protect inclusion of <sys/times.h> with HAVE_SYS_TIMES_H check
6929 builtins/Makefile.in
6930 - update dependencies for times.o
6935 - moved functions dealing with struct timevals here from general.c
6939 - moved functions dealing with clock_ts here from general.c
6940 (print_time_in_hz renamed to print_clock_t)
6943 - moved extern declarations for timeval_to_secs and print_timeval
6945 - moved extern declarations for clock_t_to_secs and print_clock_t
6949 - calls to print_time_in_hz changed to print_clock_t
6952 - added references for lib/sh/timeval.c and lib/sh/clock.c
6955 - clock.o and timeval.o are now included in libsh.a
6960 - make sure last_command_exit_value is updated before running a
6961 DEBUG trap in the cm_simple case of execute_command_internal
6963 lib/readline/display.c
6964 - new function, static void redraw_prompt (char *), used to
6965 redraw the last line of a multiline prompt that possibly
6966 contains terminal escape sequences
6967 - call redraw_prompt from _rl_redisplay_after_sigwinch
6972 - new struct with names of string-valued readline variables and
6973 handler functions to call when the variable is set
6974 - changed rl_variable_bind to use functions to find boolean vars
6975 and string vars in their respective lists
6976 - new function, bool_to_int, to translate a boolean value that may
6977 appear as an argument to `set <boolean-var-name>' to 1 or 0
6978 - new function, hack_special_boolean_var, called if the element in
6979 the boolean_vars struct has the V_SPECIAL flag set, to provide
6980 any necessary other action when a boolean variable is set
6981 - new functions to be called when each string variable is set;
6982 called by rl_variable_bind
6985 - do_piping no longer sets pipes to O_TEXT mode if __CYGWIN32__
6991 - parameter_brace_patsub now mallocs a local copy of `patsub', because
6992 if it starts with a `/' we increment it, and functions down the call
6993 chain will free that on an error (and if we pass the incremented
6994 value, will try to free unallocated memory)
6995 - pos_params now short-circuits and returns a null string immediately
6996 if start == end, meaning we want 0 positional parameters
7001 - fixed pat_subst to correctly handle a null replacement string with
7002 a null pattern string prefixed with `%' or `#'
7007 - don't import shell functions from the environment if the shell was
7013 - if a command substitution is being performed inside a shell function,
7014 catch `return' in command_substitute so that a return inside the
7015 command substitution doesn't jump back to execute_function (or one
7016 of its brethren) and go on with the command
7019 - in history_delimiting_chars, if the first line is `for var' and
7020 command_oriented_history is active, we don't want a semicolon if
7021 the next token to be read is `in', but we do want one otherwise.
7022 All we can do is check shell_input_line and see if the next chars
7023 are `in' -- if so, we return " "
7028 - don't allow `hash -p /pathname/with/slashes name' if the shell
7031 doc/{bash.1,bashref.texi}
7032 - updated description of restricted shell mode
7034 lib/readline/display.c
7035 - fixed a bug in _rl_update_final which used the inv_lbreaks array
7036 to index into visible_line
7039 - waitchld() need not go through the pain of setting up an environment
7040 to execute traps on SIGCHLD if children_exited == 0
7041 - waitchld returns -1 if waitpid() returns -1 with errno == ECHILD,
7042 indicating that there are no unwaited-for child processes, and it
7043 has not yet reaped any dead children
7044 - wait_for, wait_for_single_pid return -1 if waitchld() returns -1
7045 - new function, mark_all_jobs_as_dead
7046 - wait_for_background_pids calls mark_all_jobs_as_dead if
7047 wait_for_single_pid returns -1 with errno == ECHILD, since there are
7048 no unwaited-for child processes
7051 - tentative change: subshells started for command substitution no
7052 longer unconditionally disable job control
7057 - new function: save_token_state(). Saves the value of last_read_token
7058 and the two previous tokens in an allocated array and returns the
7060 - new function: restore_token_state(ts). TS is an array returned by
7061 save_token_state. last_read_token and the two previous tokens are
7062 set from the values in TS
7065 - run_pending_traps calls save_token_state and restore_token_state
7066 around the call to parse_and_execute, which will call the parser
7067 and possibly leave it in a state where reserved words will not be
7068 recognized (_run_trap_internal, too)
7073 - if sendmail is used as $RMAIL, pass `-i -t' as arguments so changes
7074 made by the user to the recipient headers in the message are
7080 - if histverify has been set, make sure a `:p' modifier to a history
7081 expansion prints the result
7084 - new extern variable, xpg_echo, set to 1 if DEFAULT_ECHO_TO_USG is
7085 defined and 0 otherwise
7086 - echo_builtin now sets the initial value of do_v9 from xpg_echo
7089 - new shopt option, `xpg_echo', turns backslash escape expansion by
7090 `echo' on and off at runtime
7092 builtins/{bash.1,bashref.texi}
7093 - documented new `xpg_echo' shell option
7095 tests/{builtins.tests,builtins2.sub,shopt.tests}
7096 - changes for new `xpg_echo' shell option
7099 - changes for FreeBSD-3.x ELF to add `-rdynamic' to LOCAL_LDFLAGS.
7100 This allows dynamic loading of builtins
7103 - changes to handle FreeBSD-3.x elf or a.out object file formats
7107 [bash-2.04-beta1 released]
7112 - wait_for returns -1 only if the shell is currently executing the
7113 `wait' builtin, since that's the only thing that cares
7116 - moved cases of close_fd_bitmap to before calls to do_piping to
7117 handle some pathological cases
7122 - save the command line in execute_simple_command before making the
7123 export environment, since maybe_make_export_env clobbers
7124 the_printed_command if there are exported functions
7128 configure.in,config.h.in
7129 - check explicitly for setvbuf; define HAVE_SETVBUF if found
7132 - change opt_gnu_malloc to opt_bash_malloc, since the bash malloc
7133 is not really the gnu malloc anymore
7134 - new argument, --with-bash-malloc, identical to --with-gnu-malloc
7135 - AC_DEFINE(USING_BASH_MALLOC) if opt_bash_malloc is enabled
7138 - new #define for USING_BASH_MALLOC
7141 - updated installation section to add --with-bash-malloc and
7142 change description of --with-gnu-malloc
7145 - change name of function to sh_setlinebuf, just returns 0 if
7146 HAVE_SETVBUF and HAVE_SETLINEBUF are undefined
7147 - prefer setvbuf to setlinebuf if we have both
7148 - if we're using setvbuf, use a local buffer for stdin and stdout
7149 local buffer is BUFSIZ unless we're using the bash malloc
7150 (USING_BASH_MALLOC is defined), in which case it's 1008 (which
7151 the bash malloc rounds up to 1024)
7156 - if USING_BASH_MALLOC is defined, set the max buffer size to 8176,
7157 which the bash malloc rounds up to 8192
7162 - new function, pcomp_filename_completion_function, a wrapper for
7163 filename_completion_function that dequotes the filename first
7166 - changed bash_directory_completion_matches to dequote the filename
7167 before passing it (indirectly) to filename_completion_function
7170 - change execute_command to defer calling unlink_fifo_list until any
7171 shell function has finished executing (variable_context == 0)
7174 - added AC_CYGWIN, AC_MINGW32, AC_EXEEXT
7179 - expand_word_internal(): changes some things to avoid small (2 or 3
7180 byte) calls to xmalloc -- added a label and some gotos (BEWARE)
7181 - changed make_dev_fd_filename so it doesn't call sprintf anymore
7186 - make execute_select_command handle the effects of the `continue'
7192 - RELSTATUS changed to `beta2'
7196 [bash-2.04-beta2 released]
7201 - make run_startup_files check for ssh2 as well as ssh1
7206 - make sure parsing conditional commands isn't confused by unexpected
7207 tokens (like `[[)]]')
7210 - fix get_job_spec to return NO_JOB for numeric job specs that are
7211 beyond the size of the jobs table
7214 - change describe_command to report `not found' if a path search
7215 returns the same string as the command name and the command name
7216 does not match an executable file. This has implications for
7217 `type' and `command -[vV]'.
7218 - if a command is not found in $PATH, but an executable file with the
7219 name supplied exists in the current directory, make the command
7220 into a full pathname for the `command' builtin. This has
7221 implications for `type' and `command -[vV]'
7224 - new function, expand_prompt_string, expands prompt string and
7225 returns the string passed if an error occurs
7228 - extern declaration for expand_prompt_string
7231 - decode_prompt_string calls expand_prompt_string instead of
7232 expand_string_unsplit
7237 - return EXECUTION_FAILURE if ferror(stdout) is true
7242 - if LC_ALL is unset, call setlocale(LC_ALL, lc_all), because lc_all
7243 holds the default locale
7247 lib/readline/shell.c
7248 - define NULL as 0 if it's not defined
7249 - change single_quote to allocate 4 characters in new string for
7250 each character in the old one (like builtins/common.c:single_quote)
7253 - when a locale variable (LC_*) is unset, pass "" to setlocale()
7254 to get the default locale set, since value is NULL
7257 - new function, sh_makepath(char *path, char *dir, int flags)
7260 - changed version to beta3
7263 - changed describe_command to use sh_makepath()
7266 - removed private declaration of mkpath(), changed to use sh_makepath
7269 - changed make_absolute to use sh_makepath
7270 - changed full_pathname to use sh_makepath
7273 - removed private definition of make_full_pathname, changed to use
7276 doc/{bashref.texi,bash.1}
7277 - added text to description of `getopts' to make it clear that getopts
7278 may be used to parse option characters other than letters, and
7279 that `:' and `?' may not be used as option characters
7282 - when processing a jump_to_top_level(EXITPROG), make sure the shell
7283 doesn't think it's still in a function by setting variable_context
7287 - a skeletal man page for rbash, adapted from debian
7290 - try to find a default editor if EDITOR is unset, rather than blindly
7295 support/config.{guess,sub}
7296 - many changes from the latest `automake' distribution, from the
7301 lib/readline/keymaps.h, lib/tilde/tilde.h
7302 - added support for C++ compilation (`extern "C" {...}')
7307 - in process_substitute, make sure the child resets the O_NONBLOCK
7308 flag on the file descriptor opened for read to a named pipe
7311 - new function, raw_job_exit_status, returns exit status of last job
7313 - change job_exit_status to call raw_job_exit_status and pass the
7314 result to process_exit_status
7315 - in notify_of_job_status, get termination status from call to
7316 raw_job_exit_status, rather than the first job in the pipeline
7317 (fixes debian bug #15165)
7320 - changed bash_history to not add shell comment lines to the history
7321 file (fixes debian bug #21901). Uses new function shell_comment(L)
7322 which returns 1 if L is a shell comment line. Doesn't handle
7323 comments embedded in lines yet
7326 - when running in POSIX.2 mode, bash no longer performs word splitting
7327 on the expanded value of the word supplied as the filename argument
7328 to a redirection operator (fixes debian bug #30460)
7331 - added new redirection stuff to POSIX Mode section (from previous fix)
7336 - removed extra semicolon at end of HASH_ENTRIES define
7339 - replaced toggling of disallow_filename_globbing flag with setting
7340 flags in redirection word to include W_NOGLOB if the shell is in
7341 POSIX mode and not interactive when expanding the filename argument
7347 - new function, backslash_quote_for_double_quotes(char *), quotes
7348 characters special when in double quotes in the string passed as
7350 #ifdef PROMPT_STRING_DECODE; called by decode_prompt_string
7353 - extern declaration for backslash_quote_for_double_quotes
7356 - call backslash_quote_for_double_quotes instead of backslash_quote
7357 in decode_prompt_string
7362 - before expanding the \u prompt string escape sequence, make sure
7363 current_user.user_name is non-null and call get_current_user_info
7368 support/mkversion.sh
7369 - changes to avoid relying on floating point output format, which
7370 can be locale-specific
7375 - changes to named_function_string (for normal function printing)
7376 and print_function_def (for printing function definitions embedded
7377 in other commands) to print redirections that should be attached
7378 to the function as a whole after the closing brace
7381 - tests for printing functions with attached redirections, called by
7386 lib/readline/complete.c
7387 - if we're completing files in the root directory and executing the
7388 visible-stats code, don't pass an empty pathname to
7389 rl_directory_completion_hook, because, for bash, that will be
7390 expanded to the current directory. Just pass `/' instead.
7393 - fix to tilde_expand_word for Cygwin to avoid creating pathnames
7394 beginning with `//' if $HOME == `/'
7397 - don't bother with the exportstr validation on cygwin systems,
7398 or even using exportstr at all, since that system has weird
7399 environment variables
7404 - new option, --enable-xpg-echo-default, new name for
7405 --enable-usg-echo-default (which is still present for backwards
7408 configure.in, config.h.in, builtins/echo.def
7409 - DEFAULT_ECHO_TO_USG -> DEFAULT_ECHO_TO_XPG
7414 - changed a couple of tests to avoid creating files with known
7418 - changed to create files in /tmp/rlvers
7420 support/mksignames.c
7421 - now understands the POSIX.1b real-time signal names on systems
7426 [bash-2.04-beta3 released]
7431 - try some more things to avoid race file replacements in
7435 - two new functions:
7436 get_current_prompt_level: returns 2 if current prompt is $PS2,
7438 set_current_prompt_level: sets current prompt to $PS2 if arg
7439 is 2, $PS1 otherwise
7442 - make sure to copy the `line' member in copy_arith_for_command
7445 - free up `lwords' and `line' after evaluating any command or shell
7446 function in gen_compspec_completions
7447 - after filtering any matches specified by cs->filterpat in
7448 gen_compspec_completions, free ret->list (the members have
7449 already been copied or freed by filter_stringlist)
7452 - free what find_cmd_name returns after calling the programmable
7458 - make call_expand_word_internal set w->word to NULL if either
7459 expand_word_error or expand_word_fatal is returned
7464 - two new functions: set_current_prompt_level(int) and
7465 get_current_prompt_level() to set and get the `level' of
7466 current_prompt_string (1 if $PS1, 2 if $PS2)
7469 - extern declarations for {get,set}_current_prompt_level
7471 builtins/evalstring.c
7472 - add an unwind_protect to save and restore the current prompt
7473 string pointers using {get,set}_current_prompt_level
7478 - changed release status to `beta4'
7482 [bash-2.04-beta4 released]
7487 - moved checks for non-unix variants to beginning of tests
7489 Makefile.in, {builtins,support}/Makefile.in
7490 - added some $(EXEEXT) suffixes to generated programs for non-Unix
7496 - make get_current_prompt_level return 1 if current_prompt_string is
7497 NULL (as it would be while sourcing startup files)
7500 - rmdir $TDIR in the exit trap
7501 - move the exit trap after we successfully create $TDIR
7506 - several changes to split_at_delims to make non-whitespace
7507 delimiters create separate fields containing those delimiters,
7508 like the shell parser does with meta characters. This allows
7509 redirection operators, for example, to be treated as separate
7510 words by the programmable completion code
7512 examples/complete/complete-examples
7513 - added new function: _redir_op, which return true if the word
7514 passed as an argument contains a redirection operator (just
7516 - changed set completion function to use _redir_op as an example
7519 - make parse_string_to_word_list save and restore the value of
7520 shell_input_line_terminator, since an assignment like
7521 COMPREPLY=() inside a shell function called by the programmable
7522 completion code can change shell_input_line_terminator out from
7523 underneath shell_getc(). shell_getc will set the input line
7524 terminator to EOF when it gets EOF from the getter function, and
7525 the string getter function returns EOF at EOS. parse_and_execute
7526 tests for EOS directly and never gets EOF from shell_getc, so it
7527 does not have this problem.
7531 lib/readline/funmap.c
7532 - #define QSFUNC like in complete.c
7533 - cast _rl_qsort_string_compare to a QSFUNC * in the call to qsort
7535 lib/readline/terminal.c
7536 - correct a typo in usage of the __EMX__ preprocessor define
7537 - fix a reversed usage of `#if defined (__DJGPP__)' in
7539 - remove extern declarations for _rl_in_stream and _rl_out_stream
7541 lib/readline/rlprivate.h
7542 - add extern declaration for _rl_in_stream, since there's already
7543 one for _rl_out_stream
7546 - if bash is using ulimit(2), make sure that getfilesize() returns
7547 the value multiplied by 512 to convert it from a number of blocks
7548 to a number of bytes
7553 - make sure execute_command_internal sets last_command_exit_value
7554 correctly when inverting the return value of a (...) subshell
7557 tests/{run-invert,invert.{tests,right}}
7558 - new tests for return value inversion
7561 - compile without bash malloc on m68k-motorola-sysv due to a file
7562 descriptor leak in closedir(3) -- the motorola implementation
7563 requires that freed memory be readable so it can free the dirent
7564 and then look back at it to find the file descriptor
7567 - fix negative exponents in v**e to return an eval error
7572 - changed status to beta5
7575 - fixed a problem with checking the wrong process when checking to
7576 see whether or not we need to reset the tty state. The old code
7577 checked the first process in a pipeline; the new code checks all
7578 processes in the pipeline to see whether any of them exited due
7579 to a signal or was stopped. If none were signalled or stopped,
7580 the code uses the exit status of the last process in the job's
7585 [bash-2.04-beta5 released]
7588 - call set_current_prompt_level instead of setting prompt_string_pointer
7593 [bash-2.04-beta5 re-released to net]
7598 - make sure SIGCHLD is defined in initialize_shell_signals before
7599 trying to use it in sigdelset() (DJGPP fix)
7604 - include <unistd.h> before <shtty.h>
7605 - separate tests for ONLCR, ONOCR, ONLRET to cope with systems like
7606 DJGPP that don't implement the full POSIX termios option set
7609 - set TMPDIR only if it's not already set
7612 - if a system doesn't define _POSIX_SOURCE but has a `struct dirent'
7613 without a d_ino member, define REAL_DIR_ENTRY to 1 so all entries
7617 - check for <arpa/inet.h> header file
7620 - add HAVE_ARPA_INET_H define
7623 - don't compile unless HAVE_NETWORK, HAVE_NETINET_IN_H, and
7624 HAVE_ARPA_INET_H are all defined in config.h or config-bot.h
7629 - if we have a construct like "${@:-}", we need to note that we're
7630 not using whatever is in $@ (we're using the rhs), so the special
7631 double-quoting $@ rules do not apply
7635 lib/readline/signals.c
7636 - declare SigHandler before using it on non-POSIX systems
7638 lib/sh/{zread,zwrite}.c
7639 - include <sys/types.h> unconditionally
7642 - m68k-motorola-sysv should be m68k-sysv in the section that sets
7643 opt_bash_malloc to no for certain systems
7645 builtins/complete.def
7646 - fixed a typo (stoppped) when printing out completion actions
7651 - include <arpa/inet.h> if it's present
7654 - new macro, BASH_FUNC_INET_ATON, checks for inet_aton(3) including
7655 <netinet/in.h> and <arpa/inet.h>, which some systems require to
7656 resolve the function
7659 - if autoconf can't fund inet_aton on its own, try BASH_FUNC_INET_ATON
7662 - fixed a memory leak in gen_wordlist_completions
7663 - changed gen_wordlist_completions to do prefix-matching against the
7664 word being completed
7666 doc/bash.1, lib/readline/doc/rluser.texinfo
7667 - documented the change in behavior of the -W option to complete and
7671 - if parse_symbolic_mode() returns -1, symbolic_umask needs to return
7672 -1 as well, otherwise the umask will be changed inappropriately
7675 - always compile in getc_with_restart and ungetc_with_restart
7678 - yy_stream_get and yy_stream_unget now call getc_with_restart and
7679 ungetc_with_restart, respectively, to avoid problems with some
7680 systems not restarting the read(2) when signals that bash handles
7681 are received during the read (since bash installs its signal
7682 handlers without the SA_RESTART flag)
7684 lib/readline/complete.c
7685 - don't default rl_completion_case_fold to 1 if __DJGPP__ is defined
7690 - renamed `varlist' to `subst_assign_varlist' and made it global
7693 - when running a SIGCHLD trap, need to unwind-protect
7694 subst_assign_varlist and set it to NULL before running the trap
7695 command (fix from ericw@bestnet.org and doogie@debian.org)
7699 lib/readline/doc/rltech.texinfo
7700 - document rl_funmap_names()
7705 - change split_at_delims to set the current word more appropriately
7706 when the cursor is between two words. Should probably change this
7707 again to set the current word like this only when the cursor is at
7708 whitespace or another delim just before the word start
7713 - more checks for flag bits being defined before using them
7718 - fix typo in COPY_EXPORTSTR definition
7723 - changed split_at_delims so that if the cursor is at whitespace
7724 between words, and we're interested in the current word (cwp != NULL),
7725 make a new empty word and set the cwp to that word
7728 - support for setting LC_NUMERIC locale category based on value of
7729 LC_NUMERIC shell variable
7732 - LC_NUMERIC is now treated specially
7734 doc/{bash.1,bashref.texi}
7735 - LC_NUMERIC updates
7740 - fix to avoid freeing memory twice
