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

Some systems, like SVR4, have a B_ERROR define in a file included by jobs.c and nojobs.c, and it causes a warning 7/31 ---- fnmatch.c - rewrote most of fnmatch(), so that it now implements ksh-88 style pattern matching (`[@+*?!](patlist)') if the FNM_EXTMATCH flag is set fnmatch.h - added a define for FNM_EXTMATCH 8/4 --- lib/readline/display.c - fixed _rl_redisplay_after_sigwinch () so that it really redisplays only the portion after the final newline of a multi-line prompt [in bash-2.01.1] bashline.c - attempt_shell_completion no longer returns matches if a glob pattern matches more than one filename -- it caused too many problems [in bash-2.01.1] 8/5 --- lib/glob/glob.c - updated glob_pattern_p so that the extended matching operators are recognized pathexp.c - udpated unquoted_glob_pattern_p so that the extended matching operators are recognized - udpated quote_globbing_chars so that the extended matching operators are recognized and quoted appropriately subst.c - updated match_pattern_char so that the extended matching operators are recognized parse.y - updated read_token_word so that it parses an extended matching pattern as a single word jobs.c - if a job is suspended with SIGTSTP, and the user has set checkwinsize with `shopt', update the window size [in bash-2.01.1] pathexp.c, pathexp.h - new global variable, extended_glob, controls whether the extended pattern matching features are enabled pathexp.h - new define, FNMATCH_EXTFLAG, to be OR'd with other values for flags argument to fnmatch to enable the extended pattern matching features if extended_glob is set {pathexp,execute_cmd,bashhist,subst,test}.c, builtins/help.def - changed calls to fnmatch to add FNMATCH_EXTFLAG to the flags arg if extended_glob is non-zero lib/glob/glob.c - changed flags arg passed to fnmatch to include FNM_EXTMATCH if extended_glob is non-zero (#ifdef SHELL) 8/6 --- builtins/shopt.def - added a new `extglob' shell option, controls the value of extended_glob 8/7 --- doc/{bash.{1,html},bashref.texi} - documented new extended pattern matching operators and the `extglob' shell option tests/{extglob.{tests,right},run-extglob} - test suite for the new extended globbing features 8/8 --- parse.y, pathexp.h, lib/glob/fnmatch.c - made the extended globbing code #ifdef EXTENDED_GLOB config.h.in - added a line for EXTENDED_GLOB, controlled by configure configure.in - new option, --enable-extended-glob, controls defining of EXTENDED_GLOB (on by default) doc/bashref.texi - documented new `configure' `--enable-extended-glob' option 8/11 ---- builtins/printf.def - new `printf' builtin, implemented according to POSIX.2 spec for printf(1) Makefile.in,builtins/Makefile.in - added necessary stuff for new printf builtin 8/12 ---- lib/readline/isearch.c - change to make ^G interrupt the incremental search correctly [in bash-2.01.1] configure.in, config.h.in - configure now checks for the availability of strtoul(3) builtins/printf.def - use strtoul for the `%o', `%u', `%x', and `%X' formats if it is available 8/13 ---- tests/{printf.{right,tests},run-printf} - extensive test suite for the new `printf' builtin builtins/Makefile.in - change so that `builtext.h' is not recreated every time the source file for a builtin is changed if the contents are the same. This keeps many files from being recompiled 8/14 ---- subst.c - changed verify_substring_values so that it returns -1 for substring range errors, 0 for expression errors, and 1 for success [in bash-2.01.1] - changed parameter_brace_substring to return an error if verify_substring_values returns 0, and a null string if it returns -1. This matches the ksh93 behavior [in bash-2.01.1] trap.c - changed decode_signal so that it makes sure the first three characters of a signal name are `SIG' before allowing the `SIG' prefix to be omitted. This is so a signal spec of `T' does not match `EXIT', for instance [in bash-2.01.1] builtins/trap.def - make sure that showtrap() displays traps for signals with unknown names using the signal number [in bash-2.01.1] shell.c - make sure that `bash -r' doesn't turn on the restricted mode until after the startup files are executed [in bash-2.01.1] doc/{bash.{1,html},bashref.texi} - documented printf builtin 8/15 ---- general.c - added \xNNN escape to ansicstr -- NNN are up to three hex digits. This affects $'...', `echo -e', and printf builtins/printf.def - added \xNNN escape to bexpand -- NNN are up to three hex digits. This affects printf's `%b' conversion specifier doc/{bash.{1,html},bashref.texi} - documented new \xNNN escape sequence for echo, $'...', and printf builtins/setattr.def - make sure that a variable found in the temp environment does not cause a null string to be assigned by bind_variable (e.g., foo="" export foo ) [in bash-2.01.1] 8/18 ---- subst.c - fixed a bug that sometimes caused bad memory (pointer into an allocated block) to be passed to free when doing arithmetic substitution. Bug report from stevet@myofb.org [in bash-2.01.1] 8/19 ---- subst.c - considerable changes: moved the code that expands a single $... parameter expansion into a separate function: param_expand() This function returns a string, which may contain characters quoted with CTLESC or CTLNUL without doing word splitting - changed expand_word_internal to not remove the expansion of "$*" if the number of positional parameters is > 0 - changed the '"' case of expand_word_internal to remove quoted nulls from the resultant word if the expansion was not "$@", and the word is not a quoted null string ([] == CTLNUL, [1] == '\0') subst.c, variables.c - moved the code that handles special variables from subst.c to variables.c 8/20 ---- subst.c - rearranged the source a bit to group functions with similar operation together - fixed parameter_brace_expand so that it no longer allows indirect expansion of `special' variables - fixed parameter_brace_expand so taking the length of some of the shell's special parameters works again - moved all of the code that computes the length of a shell parameter (the ${#xxx} expansion) into parameter_brace_expand_length. Previously, the code that handled the lengths of the shell's special parameters was in parameter_brace_expand_word - valid indirect expansions are now only variable names or positional parameters 8/21 ---- subst.c - fixed param_expand to raise an expansion error if $! is being expanded and no asynchronous processes have been created - an expression error in a $((...)) arithmetic expansion now causes a non-interactive shell running in POSIX mode to exit - relaxed change of 8/20 to allow indirect references to $#, $@, $* builtins/bashref.texi - documented new posix-mode exit on invalid expressions in $((...)) lib/readline/complete.c - don't call rl_strpbrk unless rl_filename_quote_characters is not NULL -- strpbrk requires non-NULL arguments [in bash-2.01.1] 8/22 ---- bashline.c - don't make `history-expand-line' a bindable command unless BANG_HISTORY is defined, and don't compile the code for that command in unless BANG_HISTORY is defined - make history_expand_line(), tcsh_magic_space(), alias_expand_line(), and history_and_alias_expand_line() int-returning functions that return 0 for success and non-zero on error. This allows tcsh_magic_space() to just call history_expand_line() and insert a space if that returns successfully - `magic-space' is now a bindable readline command doc/bash.{1,html}, lib/readline/doc/rluser.texinfo - documented new `magic-space' bindable readline command 8/25 ---- parse.y - fixed decode_prompt_string so that values of $PWD longer than PATH_MAX don't cause buffer overruns (char t_string[PATH_MAX]) [in bash-2.01.1] general.c - fixed polite_directory_format so that values of $HOME longer than PATH_MAX don't cause buffer overruns (char tdir[PATH_MAX]) [in bash-2.01.1] subst.c - fix to expansion of $* so that the positional parameters are separated by the first character of $IFS, even when the expansion is not within double quotes, so the correct split is still performed even when IFS does not contain a space. Works for ${*}, too - fix to expansion of $@ so that the positional parameters are separated by the first character of $IFS, even when the expansion is not within double quotes, so the correct split is still performed even when IFS does not contain a space. Works for ${@}, too - new function, string_list_dollar_at(), which is to $@ as string_list_dollar_star is to $* - fixed expansion of $@ so that splitting is still done even if IFS is unset or NULL, as POSIX.2 specifies (section 3.5.2) - fixed expansion of $* so that it expands to multiple words if there is more than one positional parameter, just like $@, even if IFS is unset or NULL - new function list_quote_escapes, quotes (with CTLESC) all CTLESC and CTLNUL characters in each member of the list tests/dollar-{at,star}.sh - combined into dollar-at-star, changed run-dollars accordingly 8/26 ---- Makefile.in - make the `tests' target use $(SHELL) instead of hardcoding `sh' 8/29 ---- subst.c - expand_word_list_internal now takes a flags word as the second argument, telling which expansions to perform on the WORD_LIST - broke expand_word_list_internal into several functions: one each to do brace expansion, glob expansion, and the `normal' shell expansions - new extern function: expand_words_shellexp() to perform the `normal' shell expansions on a WORD_LIST subst.h - extern declaration for expand_words_shellexp bashline.c - fixed a problem with attempt_shell_completion where it attempted to refer to rl_line_buffer[-1] (completion at the start of the line, which means that ti == -1, which means that the test for rl_line_buffer[ti] at line 715 was an array bounds error [in bash-2.01.1] eval.c - new function, parse_string_to_word_list(), which takes a string and runs it through the parser, returning the resultant word list externs.h - new extern declaration for parse_string_to_word_list() variables.c - change assign_array_var_from_string to first split the string between the parens on whitespace, then expand the resultant list of words with all the shell expansions before doing the assignment 9/4 --- redir.c, redir.h - redirection_error is no longer a static function builtins/evalstring.c - changes to handle $( < filename ) (equivalent to $(cat filename)) as in ksh lib/readline/bind.c - added two new functions: rl_unbind_function_in_map(func, map), which unbinds all keys that execute FUNC in MAP; and rl_unbind_command_in_map(command, map), which unbinds all keys bound to COMMAND in MAP lib/readline/readline.h - extern declarations for rl_unbind_{function,command}_in_map lib/readline/doc/rltech.texi - documented rl_unbind_{function,command}_in_map builtins/bind.def - added a new option, -u FUNCNAME, which unbinds all key sequences bound to FUNCNAME in the specified (or current) keymap doc/{bash.{1,html},bashref.texi} - documented new $( < filename ) command substitution - documented new bind -u FUNCNAME option 9/5 --- shell.c - send SIGHUP to all jobs when an interactive login shell exits if the variable `hup_on_exit' is non-zero - modified run_startup_files so that if `NON_INTERACTIVE_LOGIN_SHELLS' is #define'd (perhaps in config.h.top, though there is nothing there for it), all login shells (interactive and non-interactive) run /etc/profile and one of the per-user login shell startup files builtins/shopt.def - new shopt option `huponexit' to control the value of hup_on_exit doc/{bash.{1,html},bashref.texi} - documented new `huponexit' shell option 9/8 --- builtins/common.c - changed contains_shell_metas to return 1 if a tilde appears at the start of a string or after a `=' or `:' - changed backslash_quote to quote a tilde if it appears at the start of a string or after a `=' or `:' lib/readline/complete.c - moved rl_tilde_expand to util.c; it doesn't really have anything to do with completion - moved insert_text to readline.c, renamed it _rl_replace_text (since that's really what it does), changed callers - moved code that postprocesses the list of completion matches into a new function: postprocess_matches - new implementation of tcsh-like menu completion in a single new function: rl_menu_complete lib/readline/{funmap.c,readline.h} - necessary declarations for binding rl_menu_complete to the new `menu-complete' command doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo - documented new `menu-complete' bindable readline command 9/9 --- jobs.c - delete_job should print a warning only if subshell_environment is 0, so we don't print bogus warnings when shell scripts without a leading #! are executed 9/10 ---- builtins/read.def - fixed the code so that the `read' is automatically restarted when it returns -1 with errno == EINTR. SIGINT is handled by the interrupt handler, since interrupt_immediately is set to 1, so this handles things like SIGCHLD [in bash-2.01.1] 9/11 ---- test.c - reorganized the code slightly to make it easier to add the ksh-like [[...]] compound command test.h - new file, with extern declarations for functions available in test.c externs.h - moved declaration of test_command to test.h builtins/test.def - include `test.h' 9/16 ---- {command,make_cmd,dispose_cmd,externs,subst}.h parse.y, subst.c {make,dispose,copy,print,execute}_cmd.c - changes to add the new ksh-93 compatible [[...]] conditional command configure.in - new enable option, --enable-cond-command, to compile in the [[...]] command code config.h.in - new #define, COND_COMMAND, to compile in the [[...]] command code tests/{run-cond,cond.{tests,right}} - test suite for the new [[...]] command {builtins,lib/{readline,glob,tilde}}/Makefile.in - explicit dependencies for .o files on .c files for losing makes like Solaris doc/{bash.{1,html},bashref.texi} - documented the new `[[' compound command - documented the test/[ builtin behavior based on the number of arguments in the description of the builtin - made a new section for conditional expressions that just lists the available primaries -- the connectives and other operators are listed in the description of the [[ command and the test/[ builtin 9/18 ---- builtins/set.def - minus_o_option_commands is now a global function so the shopt code can use it - minus_o_option_commands now takes an argument telling it which options to print, just like list_minus_o_options - new function, print_minus_o_option, which prints the value of a `set -o' option either in the traditional format or in the format used by `set +o' - changed list_minus_o_opts and minus_o_option_commands to call print_minus_o_option builtins/shopt.def - `shopt -p' now causes output to be printed in a format reusable as input (the format is a series of shopt commands, like the output of `set +o') - fixed a bug that made `shopt -so' and `shopt -uo' not work - fixed list_shopt_o_options so that `shopt -op' acts like `set +o' - fixed list_shopt_o_options to that `shopt -op optname' prints the value of optname in a reusable format - fixed list_some_o_options so that `shopt -ops' and `shopt -opu' work and display output in a reusable format 9/19 ---- doc/{bash.{1,html},bashref.texi} - documented new `shopt -p' behavior shell.c - made `bash +o' display the same output as `set +o' and then start an interactive shell (previously `bash -o' and `bash +o' displayed the same thing) builtins/common.h - added prototypes to the extern function declarations 9/22 ---- builtins/evalstring.c - fixed the DISCARD case of the jump_to_top_level so that it doesn't try to call dispose_command(command) after the `pe_dispose' unwind frame gets run, since that disposes the command 9/23 ---- test.[ch] - test_eaccess is now a global function so that globbing code can use it lib/glob/glob.c - rewrote glob_vector to be slightly more efficient and to not read the directory if the filename pattern does not contain any globbing chars. This satisfies the POSIX requirement that read permission is not required for a directory when the pathname component does not contain a pattern character (bug reported by jsm28@cam.ac.uk) subst.c - fixed parameter_brace_expand so that ${array[@]} and ${array[*]} behave correctly when IFS is unset or set to something that does not contain a space (they should result in separate words, just like $@ and $*) tests/{run-array2,array-at-star,array2.right} - tests for the expansions of ${array[@]} and ${array[*]}, derived from the tests in dollar-at-star 9/24 ---- jobs.c - fixed cleanup_dead_jobs so that it doesn't remove the job containing last_asynchronous_pid from the job table. This fixes the POSIX.2 `wait' requirement problem 9/25 ---- parse.y - added `\r' escape sequence to the prompt expansion code lib/readline/chardefs.h - added defines for ISOCTAL, OCTVALUE, isxdigit (if not defined), and HEXVALUE lib/readline/bind.c - added `normal' echo/printf-like backslash escapes to the key sequence translation code, with the addition that \d expands to RUBOUT. This means that key sequence definitions (before the `:') and macro values may contain these special backslash-escape sequences - now that we can translate octal escape sequences in key bindings, change _rl_get_keyname so that it turns characters with values 128-159 inclusive into octal escape sequences (\200-\237), since those characters are not ASCII or ISO Latin 1 doc/{bash.{1,html},readline.3}, lib/readline/doc/rluser.texinfo - documented new backslash escapes for readline key sequence and macro translation builtins/pushd.def - new function, get_dirstack_from_string(char *string), returns an element from the directory stack or null, treating the argument exactly as `dirs string' would, with the exception that if the first character of `string' is not `+' or `-', a `+' is assumed builtins/common.h - new extern declaration for get_dirstack_from_string general.c - added code to bash_special_tilde_expansions to get the expansion using get_dirstack_from_string() if the first character of the tilde-prefix is a digit or the first character is a `+' or `-' and the second is a digit tests/dstack.{tests,right} - renamed from dirstack.{tests,right} tests/dtack2.{tests,right} - new tests for the directory stack tilde expansion code tests/run-dirstack - now runs both dstack and dstack2 10/3 ---- trap.c - reordered header file inclusion for irix 4 execute_cmd.c - fixed select_query so that a reply that is not a number is treated the same as a numeric reply that is out of range lib/readline/util.c - added a backwards-compatibility definition of _rl_savestring() builtins/set.def - initialize_shell_options now takes an argument saying whether or not we should parse $SHELLOPTS from the environment. The shell does not parse the value if it's restricted, running setuid, or running in `privileged mode' shell.c - change call to initialize_shell_options to add the correct argument builtins/common.h - changed extern declaration for initialize_shell_options doc/{bash.{1,html},bashref.texi} - added note that the shell ignores $SHELLOPTS in the environment at startup if running in privileged mode - added note that the restricted shell does not parse $SHELLOPTS from the environment at startup 10/6 ---- aclocal.m4 - change BASH_RLIMIT_TYPE so that it looks for rlim_t in as well as , for Solaris 2.6 - new macro, BASH_LARGE_FILE_SUPPORT, to enable special compilation options for large files on Solaris 2.6 (from eggert@twinsun.com) mailcheck.c - the `file_size' member of the FILEINFO struct should be of type `off_t' - the `size' variable in file_has_grown should be of type `off_t' - the RESET_MAIL_FILE macro should initialize file_size to 0, not 0L builtins/Makefile.in - LDFLAGS and LOCAL_LDFLAGS are now set by configure - `mkbuiltins' is now created from `mkbuiltins.o' instead of directly from the source to the executable builtins/evalfile.c - fixed _evalfile so that it handles large files correctly on systems where the st_size member of `struct stat' will not fit into an `int' builtins/mkbuiltins.c - don't assume that st_size fits into an int input.[ch] - the `b_size' member of a struct BSTREAM is now of type `size_t' - changed third argument to make_buffered_stream to size_t; changed caller - changed `size' variable in fd_to_buffered_stream to type `size_t' general.h - include if HAVE_SYS_RESOURCE_H and RLIMTYPE are both defined, for possible necessary definition of RLIMTYPE (e.g., on Solaris 2.6) {execute_cmd,jobs}.c, builtins/times.def - don't include explicitly if RLIMTYPE is defined, since general.h will include it in that case lib/readline/bind.c - new function, char *_rl_read_file(filename, sizep), which reads FILENAME into a malloced buffer, returning the buffer and the size of the buffer in *SIZEP lib/readline/histfile.c - changed read_history_range and history_truncate_file to handle large files hashcmd.c - find_hashed_filename should not add `./' to the front of a pathname that already begins with `./' 10/8 ---- support/config.sub - recognize `hppa2.0' as a valid machine architecture aclocal.m4 - changed BASH_CHECK_LIB_TERMCAP so that `gnutermcap' is not chosen if `$prefer_curses' is set to something bashhist.c - don't use HISTCONTROL or HISTIGNORE to remove lines from the second and subsequent lines of a multi-line command (current_command_line_count > 1). Old code did this only when command-oriented-history was enabled doc/{bash.{1,html},bashref.texi} - changed descriptions of HISTCONTROL and HISTIGNORE to state that these variables are not applied to the second and subsequent lines of a multi-line command builtins/hash.def, {copy,dispose}_cmd.c - include "bashtypes.h" -- cray machines need it because of their oddball definition of `word' configure.in - changed check of ${host_cpu} to check for `*cray*' and `*Cray*' when deciding whether to include the GNU malloc, since it seems that ${host_cpu} gets set to `CrayYMP' 10/9 ---- configure.in - look for strtod and strtol in libc - make lib/sh directory in build directory if not there - create lib/sh/Makefile config.h.in - added HAVE_STRTOD and HAVE_STRTOL Makefile.in - changes for lib/sh/libsh.a (shell library) builtins/printf.def - took out the `#ifdef STRTOUL' code, since strtoul is in libsh.a, and will be resolved from there if it's not in libc variables.c - call strtol() instead of string_to_long() general.c, general.h - removed string_to_long - changed legal_number to use strtol so it correctly sets errno to ERANGE on overflow - moved bash_getcwd_errstr here from lib/sh/oslib.c externs.h - moved extern declarations for functions defined in libsh to a separate section of the file, added extern declarations for other functions in libsh builtins/ulimit.def - changed macro definition for string_to_rlimtype to call strtol directly instead of string_to_long lib/sh/clktck.c - moved get_clock_tck to its own file, since it's compiled in unconditionally 10/10 ----- lib/sh/getenv.c - moved getenv() and __getenv() here from lib/sh/oslib.c lib/sh/{setlinebuf,strerror,strcasecmp}.c - moved {setlinebuf,strerror,strcasecmp}() from oslib.c to individual files lib/sh/Makefile.in, Makefile.in - changes for new files in lib/sh aclocal.m4 - new macro BASH_SYS_RESTARTABLE_SYSCALLS, which does what AC_SYS_RESTARTABLE_SYSCALLS does, but using posix sigaction() configure.in - call BASH_SYS_RESTARTABLE_SYSCALLS if ac_cv_sys_restartable_syscalls is `no' 10/13 ----- builtins/jobs.def - catch out-of-range jobs better in disown_builtin configure.in - don't build with GNU malloc on cygwin32 trap.c - change signal_name to handle the case where signal_names[sig] is NULL, which can happen on cygwin32 execute_cmd.c - changes to do_piping to make pipes text mode (O_TEXT) on cygwin32 cross-build - new directory with cache files and other stuff for cross-compiling bash (currently only for building for cygwin32 on a Unix machine) cross-build/cygwin32.cache - new file containing configuration variable assignments for cygwin32 that would otherwise require a default case for AC_TRY_RUN configure.in - source ${srcdir}/cross-build/cygwin32.cache on CYGWIN32 systems if we're cross-compiling on a unix machine - set $CC_FOR_BUILD for cygwin32 cross-compiling environment Makefile.in - CC_FOR_BUILD is now a variable set by configure builtins/mkbuiltins.c - only check for read(2) returning <= 0 in extract_info() (error and exit on < 0, warning and return on == 0) builtins/evalfile.c - only check for read(2) returning <= 0 in _evalfile() (error and and failure return on < 0, success on == 0 while short-circuting rest of operation) 10/14 ----- vprint.c - moved to lib/sh/vprint.c lib/sh/Makefile.in - added entries for vprint.[co] in the appropriate places cross-build/win32sig.h - a version of signames.h for cross-compiling for the CYGWIN32 environment on a Unix machine (from noer@cygnus.com) aclocal.m4 - made all cases of AC_TRY_RUN and AC_TRY_COMPILE have reasonable default cases for cross-compiling, and tell the user what they are Makefile.in - removed vprint.c from shell sources and vprint.o from shell objects - added a level of indirection for signames.h -- the variable SIGNAMES_H is set by configure to either `lsignames.h' or a file for a cross-compilation environment (currently only the cygwin32 stuff is supported). Then that file is copied to `signames.h'. `lsignames.h' is created by `mksignames' as was previously used to create signames.h directly configure.in - set SIGNAMES_H to either `$(srcdir)/cross-build/win32sig.h' or `lsignames.h' as appropriate, substitute into Makefile 10/15 ----- builtins/Makefile.in - CC_FOR_BUILD is now set by configure and used to build mkbuiltins and psize.aux variables.h - new variable attribute `att_tempvar', set if the SHELL_VAR * was constructed on the fly from the temporary environment variables.c - find_name_in_env_array now sets the `att_tempvar' attribute on the SHELL_VAR it creates findcmd.c - search_for_command now disposes the SHELL_VAR created by searching the temporary environment for $PATH, if it is found there - _find_user_command_internal also disposes of the SHELL_VAR if it has the `att_tempvar' attribute set builtins/setattr.c - show_name_attributes looks in the temporary environemnt, so it needs to dispose the SHELL_VAR if it has the att_tempvar attribute set subst.c - parameter_brace_expand_word now disposes of the SHELL_VAR returned by find_variable if it has the att_tempvar attribute set - ditto for param_expand and word_split builtins/kill.def - disallow null pid arguments instead of treating them as 0 - display a usage message and return failure if no pid or job arguments are supplied 10/16 ----- builtins/declare.def - make `var=value declare -x var' behave the same as `var=value export var' and `var=value declare -r var' behave the same as `var=value readonly var', now that we have the `tempvar' attribute 10/22 ----- jobs.c - non-interactive shells shouldn't report jobs killed by a SIGINT, even if the standard output is to a terminal - pretty_print_job should add a CR at the end of its output if the shell is interactive and asynchronous notification is being performed. This fixes the problem with extra CRs in the output of $(jobs) general.c - changed canonicalize_pathname to change `//' into `/', but leave other pathnames starting with two consecutive slashes alone 10/27 ----- lib/readline/histexpand.c - fixed history_expand so that the appearance of the history comment character at the beginning of a word inhibits history expansion for the rest of the line 10/29 ----- jobs.c,variables.c - moved set_pipestatus_array to variables.c variables.c - new function, set_pipestatus_from_exit(int), which sets the PIPESTATUS variable from a command's exit status variables.h - extern declarations for set_pipestatus_from_exit and set_pipestatus_array execute_cmd.c - fixed execute_simple_command to call set_pipestatus_from_exit if a foreground builtin or function, or a foreground null command is executed 10/31 ----- shell.c - fixed run_startup_files to detect being run by sshd, and treat that case as equivalent to being run by rshd 11/3 ---- builtins/set.def - make sure `set -a' doesn't cause SHELLOPTS to be exported when a change is made to one of the shell options 11/4 ---- pathexp.c - fix to shell_glob_filename in the code that uses a POSIX glob library 11/5 ---- jobs.c - fix cleanup_dead_jobs to hang onto the job corresponding to last_asynchronous_pid only if the shell is not interactive (this still has the problem that until a new async process is started, the job will stay in the jobs table) configure.in,aclocal.m4 - added a new macro, BASH_TYPE_U_INT32_T, to check for u_int32_t separately from int32_t, since there are systems (HP-UX 10.20) that have a define for the latter but not the former 11/6 ---- jobs.c - cleanup_dead_jobs no longer checks whether the job it is deleting corresponds to last_asynchronous_pid - notify_of_job_status and mark_dead_jobs_as_notified now will not mark the job corresponding to last_asynchronous_pid as notified if the shell is not interactive - wait_for_single_pid, if told to wait for last_asynchronous_pid, or the job of which it is a member, will take care of marking the job as notified after calling wait_for and collecting the status. This means that two successive `wait' calls for $! will succeed the first time and fail the second, as POSIX.2 specifies (take this code out if it causes problems) 11/7 ---- jobs.c - wait_for_job, if told to wait for the job corresponding to the last async pid, will mark the job as notified after waiting for it and collecting the status general.h - fixed MEMBER macro to avoid reading past end of S (it used to test s[1] before s[0], which is an error if s == "") subst.c - expand_word_internal should free ISTRING before returning if param_expand returns an error - parameter_brace_expand_word should free the memory it allocates and passes to param_expand execute_cmd.c - execute_arith_command should call dispose_words on the list returned by expand_words parse.y - after calling parse_arith_command, read_token needs to free the string value that parse_arith_command fills in, since make_word makes a copy of the string it's passed 11/10 ----- subst.c - cond_expand_word needs to free the value returned by string_list after it is run through quote_string_for_globbing parse.y - make sure cond_term frees yylval.word if it is just a `!' and it's parsed as a term negation operator variables.c - assign_array_var_from_string needs to free the word list returned by parse_string_to_word_list after calling expand_words_shellexp on it execute_cmd.c - changed execute_simple_command to avoid saving the_printed_command into command_line until just before it's needed. This should save time and prevent memory leaks on errors, but it must be watched closely to make sure that the_printed_command doesn't change out from under execute_simple_command before we copy it 11/12 ----- builtins/alias.def - alias and unalias should print error messages when passed an argument that is not an alias for printing or deletion, respectively, even if the shell is not interactive builtins/exit.def - `logout' will no longer exit a non-login non-interactive shell 11/17 ----- lib/readline/nls.c - add `koi8-r' as a legal LANG value builtins/alias.def - if `alias' or `alias -p' is executed when no aliases are defined, the return status should be 0, according to POSIX.2 11/18 ----- subst.c - changed a couple of calls to make_word_list (make_word(z), ...) to add_string_to_list (z, ...) execute_cmd.c - execute_cond_command now sets this_command_name to `[[' 11/21 ----- variables.c - all_visible_{function,variable}s and the functions they call should be compiled in only if READLINE is defined 11/24 ----- aclocal.m4 - remove some leading whitespace before preprocessor statements in BASH_KERNEL_RLIMIT_CHECK general.[ch] - fix declarations for group_member so the extern declaration in general.h agrees with the definition in general.c (fix from Andreas Schwab ) builtins/cd.def - print the new working directory if the shell is interactive and `cd -' succeeds - don't print the new working directory if it's found in $CDPATH if the shell is not interactive 11/25 ----- builtins/cd.def - fixes to bindpwd so that it copes with get_working_directory returning NULL (bug from schwab@issan.informatik.uni-dortmund.de) 12/2 ---- support/config.guess - add support for new OS name for SINIX SVR4 systems 12/3 ---- builtins/set.def - `unset' should check that a function it's trying to unset is a legal identifier only when in POSIX mode redir.c - changed here_document_to_fd to try and make sure the filename used for the here document is `more unique', since the old version would fail if two here documents were created in less than a second 12/4 ---- builtins/cd.def - POSIX.2 says that if CDPATH is used to find the new directory, and it's not relative to the current directory, the new directory name should be displayed on stdout even if the shell is not interactive 12/5 ---- parse.y - changes so that `time' is recognized as a reserved word only at the beginning of a pipeline (the last read token is one of 0, `;', `\n', `&&', `||', or `&'): o add clause to special_case_tokens that does the check and returns TIME if the conditions are met o take check for `TIME' out of CHECK_FOR_RESERVED_WORD, but leave it in the word_token_alist so that `type' still reports it as a `keyword' o new function, time_command_acceptable(), encapsulates the necessary conditions for `time' to be returned as a reserved word [bash-2.02-alpha1 frozen] 1/6/98 ------ lib/glob/fnmatch.c - fix define for isgraph so that it does not return success for space - fix strcompare() so that the call to strcoll is surrounded by #ifdef HAVE_STRCOLL 1/7 --- lib/glob/fnmatch.c - the `test' argument to brackmatch() should be of type `unsigned char' 1/11 ---- execute_cmd.c - make sure execute_arith_command sets this_command_name to `((' 1/29 ---- parse.y - make sure the code for pushing and popping strings is compiled in if either ALIAS or DPAREN_ARITHMETIC is defined, because the (( code uses push_string in the case of a nested subshell - fix cond_skip_newlines so it resets the prompt to $PS2 while parsing an unfinished conditional command dispose_cmd.c, copy_cmd.c, builtins/hash.def - fixes to not use `word' as a variable name or the name of a function parameter to get around stuff in the Cray Unix include files builtins/printf.def - return failure immediately if an illegal format character is encountered redir.c - make the code that creates here-documents behave better if the file it's trying to create already exists for some reason lib/readline/complete.c - changed print_filename to return the number of characters it outputs; changed callers to use that value. This makes columns line up when printing completion listings with filenames containing control characters doc/bash.{1,html} - fixed a typo in the quote removal section 1/30 ---- parse.y - free_string_list() needs to check that t->expander is not NULL before trying to dereference it - reset_parser() doesn't need to set pushed_string_list to NULL after calling free_string_list(), since free_string_list does it configure.in,cross-build/cygwin32.cache - fixes from Geoff Noer for better cygwin32 cross-compilation tests/printf.{tests,right} - removed test for integer overflow, since error messages differ across systems pathexp.c - fixed a problem with unquoted_glob_pattern_p that made things like `x+*' not expand correctly lib/glob/glob.c - fixed a problem with glob_pattern_p that made things like `x+*' not expand correctly builtins/cd.def - if `cd -P' is executed, or `set -o physical' has been executed, the value of $PWD after a successful cd will not contain any symlinks, regardless of whether or not the shell is in posix mode 2/3 --- lib/readline/shell.c - include or as appropriate 2/4 --- builtins/common.c - take out the code in backslash_quote() that looks for tildes to quote, for the time being - if getcwd() fails, get_working_directory now prints the error message corresponding to errno in addition to the rest of the information -- TENTATIVE CHANGE lib/sh/getcwd.c - fix from Paul Smith to make getcwd() behave better in the presence of lstat(2) failures stringlib.c - when copying the replacement string into the output string being constructed, strsub() needs to make sure enough space for the replacement string is allocated, not the length of the pattern (use REPLEN, not PATLEN) mailcheck.c - make sure make_default_mailpath() has a valid current_user struct before trying to construct the default mailpath 2/5 --- execute_cmd.c - execute_builtin needs to call run_unwind_frame if the builtin is `source' or `eval' and we're not in a subshell rather than just calling dispose_builtin_env, because not all invocations copy the temporary_env to builtin_env, and nested calls to `.' require that the temporary env given to the first persist until that first call to `.' finishes parse.y - fix to history_delimiting_chars so that function definitions like function xyz { echo a } are saved to the history correctly when command_oriented_history is enabled, but literal_history is not bashhist.c - when calling internal_error from pre_process_line, use "%s" as the format with history_value as the argument to avoid the problem with the failed history event containing printf escape sequences 2/13 ---- shell.c - if shell_initialized is non-zero, don't line-buffer stderr and stdout in shell_initialize on SunOS5 -- see if this fixes the crashing problems for scripts without a leading `#! /bin/sh' 2/17 ---- bashline.c - added diffs to _ignore_completion_names from Andreas Schwab to complete names that would otherwise be ignored with FIGNORE if they are the only possible completions. Define NO_FORCE_FIGNORE if you want this; it is not defined by default 2/19 ---- support/bashbug.sh - changed the bug-bash address to bug-bash@gnu.org examples/loadables/Makefile.in - converted from `Makefile' with some boilerplate configure variables to find the source and build directories -- still requires some hand-editing to get the right CFLAGS and LDFLAGS for shared object creation Makefile.in - create examples/loadables/Makefile with `make makefiles' configure.in - create examples/loadables directory so `make makefiles' can write a makefile there general.c - make sure initialize_groups_array always sets things up so that ${GROUPS[0]} is the user's primary group (current_user.gid) 2/20 ---- lib/readline/parens.c - change the time delay when showing matching parens from 1.5 sec to 0.5 sec 2/23 ---- shell.c - isnetconn() should call getpeername(fd,...) instead of using 0 (though fileno(stdin) should always be 0) support/config.guess - updates from master FSF copy 2/24 ---- support/man2html.c - modified version of man2html to convert bash.1 into bash.html support/Makefile.in - simple Makefile to create man2html configure.in - make sure support/Makefile is created Makefile.in - make sure support/Makefile is created and cleaned doc/Makefile.in - changes to suffix rules to say how to make .html from .1 - `bash.html' is now a makefile target, created by man2html from bash.1 rather than being hand-modified lib/sh/itos.c, general.c - new file, itos() from general.c. This is here because the implementation of strerror in lib/sh/strerror.c uses itos() Makefile.in, lib/sh/Makefile.in - changes to add itos.c in libsh.a externs.h, general.h - moved extern declaration of itos() from general.h to externs.h aclocal.m4 - changes to BASH_LARGE_FILE_SUPPORT for the LFS64_* variables in Solaris 2.6 Makefile.in - make sure configure sets CPPFLAGS in this file 2/27 ---- builtins/command.def - make sure get_standard_path returns the value of STANDARD_UTILS_PATH if _CS_PATH is defined, but confstr(3) returns 0, indicating that _CS_PATH does not have a defined value bashhist.c - fixed bash_history_inhibit_expansion() so that extended globbing expressions like *.!(c) are not history expanded if extended_glob is non-zero (shopt -s extglob has been executed) 3/2 --- Makefile.in - changed release status to `beta1' [bash-2.02-beta1 frozen] 3/17 ---- lib/readline/vi_mode.c - make sure _rl_vi_save_insert() gets a non-null UNDO_LIST pointer before trying to do anything with it jobs.c - add a call to internal_warning from wait_for_job if the job is stopped - changed notify_of_job_status to not report pipelines exiting due to SIGPIPE in non-interactive shells if the shell is compiled with -DDONT_REPORT_SIGPIPE builtins/psize.sh - some fixes to try to avoid /tmp file races and surreptitious substitutions version.c - changed the extended version info to show 1998 as the copyright year parse.y - fixes from Andreas Schwab for compilation errors when the shell is configured --disable-alias but with dparen arithmetic enabled eval.c - fixes from Andreas Schwab to make sure the input stream is popped correctly when performing an array assignment in the command argument to `bash -c', e.g., `bash -c 'A=()'' builtins/kill.def - make `kill' with no arguments print a usage message and return a failure status alias.c - fix so that rd_token doesn't dump core when trying to do alias expansion on a line containing an unclosed single quote (fix from Vasco Pedro ) builtins/cd.def - fix so that using a non-empty directory from CDPATH to construct the name of the directory to change to results in an absolute pathname of the new current working directory being displayed, as POSIX.2 specifies support/bashbug.sh - a couple of small fixes to minimize /tmp file races -- the script is still raceable, the window is just smaller 3/24 ---- variables.c - make sure assign_in_env passes a malloc'd string to expand_string_unsplit, because some of the error code assumes that it is malloc'd and frees it (bug reported by Marko.Makela@HUT.FI) 3/25 ---- doc/bashref.texi - changed the email addresses to use the @email texinfo tag trap.c - call reset_parser from the exit trap code before calling parse_and_execute, so reserved words are parsed correctly subst.c - make sure parameter_brace_patsub expands the pattern string as if the expression were not in double quotes, even if the entire expansion is enclosed in double quotes, so that quote removal on embedded double quotes is performed correctly (bug report from schwab@issan.informatik.uni-dortmund.de) 3/27 ---- support/config.guess - changes to allow Power PCs running Apple's Rhapsody to configure 3/31 ---- Makefile.in - changed release status to `beta2' [bash-2.02-beta2 frozen] 4/6 --- subst.c - make sure command_substitute does not try to set the terminal's process group to a background job [bash-2.02 frozen]
