-
- * parse.y, shell.h, new files parser.h and input.h: parser.h
- contains all of the structures necessary to parse commands; this
- file is included within shell.h. input.h contains definitions and
- structures which are used by the parser to read input; this file
- is included only by parse.y and builtins/common.c.
-
- * execute_cmd.c (find_user_command_in_path), (extract_colon_unit),
- and (user_command_matches): Fix core dumping when Bash encounters
- a trailing `:' in $PATH.
-
- * bashline.c (initialize_readline) Fix typo: name of user visible
- function is `operate-and-get-next', not `operate_and_get_next'.
-
- * machines.h: (DGUX) Fix typo '_DFOO' -> '-DFOO'.

- * execute_cmd.c (execute_command_internal) Free memory allocated
- with alloca () on machines where the alloca emulation is being
- used.
-
- * jobs.c (drain_output) Remove extra argument to select (). Now
- we expect drain_output () to work correctly.
-
- * parse.y: Many functions. New union INPUT_STREAM can contain a
- (FILE *) or a (char *). New structure BASH_INPUT contains all of
- the information that used to be in globals, namely: the address
- of the function to get a character (getter), the address of the
- function to unget a character (ungetter), the location from which
- to get or unget (INPUT_STREAM)location, the type (type), and the
- name of the stream (name). New global structure variable
- `bash_input' is the place in which the globals are stored.
-
- * shellc. (initialize_shell) Call initialize_bash_input () to zero
- the data structure used by the BASH_INPUT functions.
-
- Mon Jan 20 23:04:15 1992 Brian Fox (bfox at gnuwest.fsf.org)
-
- * parse.y (decode_prompt_string): '\s' now always returns the
- base_pathname () of the shell_name.

- versions of wait (). Add code to reap zombied children, and call
- it when forking fails the first time so we can retry the fork.

- generate .c files from the .def files. It also makes a header
- file containing external declarations, and a C source file
- containing the shell_builtins[] array.
-
- The builtins are compiled into builtins/libbuiltins.a, and then
- that file is one of the OBJECTS in bash-Makefile.

- glob pattern (and noglob_dot_filenames) don't allow it.
-
- * test.c: Avoid calling strlen () when we only care if the length

- * builtins.c: New builtin documentation: bind_builtin ().
- bashline.c: New builtin code: bind_builtin ().
- mailcheck.c: Cosmetic changes.
-
- Mon Jun 10 10:47:13 1991 Brian Fox (bfox at gnuwest.fsf.org)
-
- * machines.h: Group all of the i386 machines together. Merge SCO
- port.
-
- * jobs.c: Use SCO instead of M_UNIX.
-
- * shell.c, jobs.c, execute_cmd.c, general.c, builtins.c,
- make_cmd.c, subst.c, general.h: New file filecntl.h should be
- included wherever you needed to include fcntl.h.

- file so that those systems which do not have them get the return
- type correct.
-
- * Fixed typo in README; removed MAINTAINENCE (mispelled) from
- cpp-Makefile, since it is no longer used. Fixed mispeslling in
- machines.h of Sun Miscrosystems.
-
- * bashline.c: (command_word_completion_function) Interpret tildes

- * Makefile: Use an awk script instead of cat -s, since that
- doesn't work on USG systems. Pass MFLAGS to recursive invocations
-
- * bashline.c: All local names are now declared static.
- (display_shell_version) outputs carriage return after printing the
- shell version so that readline will not be confused. New
- functions operate_and_get_next (), and set_saved_history () are
- compatible wth the C-o command from K*rn shell.
-
- * bashline.c: Only allow enabled commands to be completed on.
-
- * braces.c: When compiled with -DSHELL, the brace_arg_separator
- character must be seen for any change to take place in
- brace_expand ().
-
- * bultins.c: (parse_and_execute) Save and restore top_level
- jmp_buf, and supply an alternate place for throws to top_level

- absolute_pathname ().
-
- * cpp-Makefile: Numerous changes include using cpp defines for
- readline and termcap targets for those `make' programs which don't

- non-null and non-empty.
-
- * execute_cmd.c (execute_command_internal) A command run in a
- subshell with `()' now runs trap 0 upon completion. Only let
- auto_resume resume stopped jobs.
-
- * execute_cmd.c: Set file descriptors to close on exec when
- executing builtin commands.
-
- Conditionalize traditional behaviour; BSD systems exec scripts
- with csh when the first line of the script is `#' by itself. This
- now only happens if the cpp define HAVE_CSH exists.
-
- * makeargs.sh: If the file /bin/csh exists, then define HAVE_CSH
- in sysdefs.h.
-
- * New define, DUP2_BROKEN determines whether the system's dup2
- doesn't handle close-on-exec correctly. Add it to SYSDEP_CFLAGS
- in the machine description. This was done for all Sequents.
-
- * execute_cmd.c (find_user_command_in_path) Use absolute_program
- () instead of absolute_pathname ().
-
- * expr.c: Allowed any valid variable name.
-
- * fc.c: Error messages do not have "fc:" in them anymore. Fixed
- memory leak in fc_readline ().
-
- * general.c (itos) Use unsigned arithmetic after determining the
- sign to about overflow errors.
-
- * execute_cmd.c, general.h: Moved macro declarations for setting
- the close on exec flag so that shell.c and jobs.c can use them.
-
- * glob.c: #include "posixstat.h" instead of "sys/stat.h" on
- systems where opendir () does not check whether the file being
- opened is a directory.
-
- * jobs.c: Improved error messages. Make the first command in a
- pipeline block reading from a pipe until the last command is
- created. This solves all sync problems.
-
- New define "getpgid (pid)" gets around differences in getpgrp ()
- calls on different systems.
-
- set_new_line_discipline () works on TERMIO systems without
- NTTYDISC.
-

- target system.
-
- * shell.h: Provide a default shell_name when argv[0] is empty or
- null. Remove leading `-' from argv[0] on recursive calls to main
- (). Exit status made Posix compliant (127) for attempts to
- execute a binary file, or a non-existant file.
-
- Test for existance of all signal definitions for
- terminating_signals array; assume nothing about target system.
-
- (throw_to_top_level) If using readline, reset readline function
- pointers to avoid interrupted completion leaving them in a funny
- state.

- POSIXfied jobs.h.
-
- Sun Feb 17 15:31:33 1991 Brian Fox (bfox at gnuwest.fsf.org)
-
- * glob.c (glob_vector (), glob_filename ()). In case of interrupt
- and compiled for Bash, then free arrays and throw to top level.
-
- * braces.c; (brace_expand) In case of an error, if compiled for
- Bash, then throw to top level. Errors are defined as:
-

-
- Wed Jan 30 17:09:06 1991 Brian Fox (bfox at gnuwest.fsf.org)
-
- * Changed xrealloc to call xmalloc if the pointer argument was
- NULL. Changed all calls to xmalloc to xrealloc if they were
- placed as a safegaurd against calling xrealloc on a NULL pointer.
-
- * replaced all occurences of <sys/stat.h> with "posixstat.h".
-
- Mon Jun 11 16:34:38 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * Change SYSV to USG everywhere (system V to "Unix Systems
- Group"). In config.h, #define USG if SYSV is defined.
- In machines.h, change `#define M_OS SYSV' to define USG instead.
-
- Tue Jun 5 15:56:12 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * execute_cmd.c: (extract_colon_unit) No longer skip leading `:'
- by itself. Instead return a string of length 0.
-
- Thu May 24 17:36:40 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * parse.y (shell_getc) Remember the value of the prompt when
- getting a new line so that history errors and other "stay here"
- faults reuse the same prompt.
-
- Wed May 23 05:12:20 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * bashline.c; Fixed extra call to rl_add_defun in
- initialize_readline ().
-
- * ulimit.c (shell_umlimit) SYSV can handle setting the break max.
- It does some things in 512 byte blocks, not 1k blocks.
-
- * builtins.c (kill_builtin) Exit value is FAILURE if any of the
- arguments couldn't be killed, else SUCCESS.
-
- * subst.c New function dequote_string (). Changed all places
- where strings were being dequoted to call this function.
- No longer give up on globbing the rest of the line if the first
- glob fails, due to file system error.
-
- * parse.y, (yylex) Only check for mail when the PS1 prompt is to
- be printed. Save value of last_command_exit_value around calls to
- execute the value of PROMPT_COMMAND.
-
- * machines.h: ports for sgi, i386 running MACH, and i386 Symmetry.
- Port for Gould 9000 - UTX/32 R2.1A

-
- Fri Apr 27 20:30:40 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * machines.h, jobs.c (initialize_jobs). Fix things to work with
- the SGI machines and OS.
-
- Thu Apr 26 13:41:34 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * builtins.c (read_builtin) New flag -r says not to ignore
- backslash-newline pair in input text.
-
- * builtins.c: add "-f" to readonly and export builtins as per
- POSIX specification.
-
- * execute_cmd.c (intern_function) report error if function cell is
- already taken and the variable is already readonly.
-
- * parse.y: Surround YYACCEPT's in "if foo YYACCEPT; else..." with
- curly braces to avoid bug in Sun's Yacc.
-
- Mon Apr 9 19:35:51 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * bashline.c: specific completion functions. e.g. M-@ completes a
- hostname, no matter what the first character of the word is, while
- C-x @ lists possible hosts.
-
- * execute_cmd.c; (execute_simple_command) Pipelined functions call
- execute_simple_command () directly so as to avoid extra forks
- (which hid SIGPIPE signals).
-
- Sun Apr 8 11:19:13 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * bashline.c:snarf_hosts_from_file () Now accepts "$include
- filename" and includes that file. No limit to nesting.
-
- Sat Apr 7 11:48:09 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * execute_cmd.c: find_user_command_in_path (); swapped cases in if
- statement for the sake of efficiency. It is quicker to check two
- variables than to call a function. Only matters in 10 percent of
- cases.
-
- * parse.y: read_secondary_line (); Cleaned up. Duplicated code,
- special case for when using readline library replaced with
- prompt_again (). New function reset_readline_prompt () keeps the
- readline prompt in sync with the Bash prompt.
-
- Thu Apr 5 13:32:35 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * machines.h: added description for Apollo running Bsd. Patched
- readline.c at rl_restart_output (), also for Apollo.
-
- * execute_cmd.c; do_redirection (): no_clobber test is only valid
- for regular files. Devices and sockets are okay to "clobber".
-
- Sun Apr 1 12:24:56 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * parse.y: reserved_word_acceptable (); added WHILE and UNTIL to
- the list of tokens which would allow bash command words to follow.
- For example: while case hi in...
-
- Wed Mar 21 11:08:11 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * nojobs.c: initialize_job_signals (); Use sigint_sighandler ()
- instead of throw_to_top_level ().
-
- * shell.c: sigint_sighandler (); Reset signal handler to this
- function so that Sys V machines can win.
-
- * parse.y: yy_readline_get (); use sigint_sighandler () rather
- than throw_to_top_level ().
-
- * parse.y: pre_process_line (); Figure out how long PATH is before
- alloca'ing the space for it.
-
- * builtins.c: history_builtin (); moved check for -s flag within
- test for any arguments.
-
- * machines.h: convex has setlinebuf, but doesn't have vprintf. It
- also apparently runs something like Bsd.
-
- * jobs.c: wait_for (). Only allow QUIT macro if bash owns the
- terminal.
-
- * mailcheck.c: free_mail_files (); Don't free a NULL pointer.
-
- Tue Mar 20 05:41:05 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * parse.y: removed "inserted ;;" error message in CASE rule.
-
- Mon Mar 12 01:25:29 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * Makefile:
-
- * Fixed typos in subst.c (quoted = 2) --> (quoted == 2)
-
- Sun Mar 11 04:28:30 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * shell.h, subst.c, expand_word_internal (). Here-documents don't
- let backslash quote double-quote while being expanded. Controlled
- by the value of QUOTED passed into expand_word_internal (). 1 ==
- expanding inside of double quotes, 2 = expanding a here document.
-
- * parse.y: handle_eof_unit () now alls reset_parser () before
- calling logout_or_exit () to prevent incorrect parsing of the
- .logout file.
-
- Sat Mar 10 16:40:10 1990 Brian Fox (bfox at gnuwest.fsf.org)
-
- * execute_cmd.c: execute_command_internal (). Fixed bug of
- backgrounded shell control structures not being in the background.
-
- * subst.c: expand_word_internal (); If a command substitution
- string was not closed properly, the shell could walk off of the
- end of a string. Fixed with simple test.
-
- * parse.y: shell_getc (); now takes argument saying how to handle
- backslash-newline. All calls to shell_getc () adjusted.
- read_token () adjusted to handle new scheme; it has to know when
- to allow backslash newline, and when to ignore.
-
- * builtins.c: echo_builtin (); Words ending in `\' handled
- incorrectly, allowing a reference past the end of the string.
- Fixed.
-
- * execute_cmd.c: find_user_command_in_path ();
- if PATH ended with a `:', then that didn't mean to search
- `.' for a file. Now it does.
-
- * builtins.c: added hack to history_builtin (). Let
- history -s args produce output the way that ARGS would if typed
- interactively. Thus "history -s "!?ema" might produce
- "ls -l emacs-18.55.tar.Z".
-
- * Added sun-cmd.termcap to the examples directory.
-
- * POSIX`fied jobs.c: new define tcsetpgrp () takes place of
- ioctl TIOCSPGRP; order of setting pgrp and terminal pgrp now
- pgrp first, then terminal next.
-
- Fri Mar 9 00:04:53 1990 Brian Fox (bfox at gnuwest)
-
- * subst.c: new function unquote_bang () removes backslashed `!'
- from single-quoted strings after extracting them.
-
- Sat Feb 24 13:40:12 1990 Brian Fox (bfox at gnuwest.gnu.org)
-
- * parse.y:read_token (); backslash doesn't quote inside
- of single quotes. Esp. newline.
-
- Tue Jan 30 09:23:13 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * cpp-Makefile, machines.h, config.h: HAVE_SETLINEBUF define is
- defined or not in machines.h.
-
- * shell.c: main (); Line buffer stdout as well as stderr.
-
- builtins.c: type_builtin (), jobs_builtin (), alias_builtin (),
- cd_builtin (), dirs_builtin (). fflush (stdout) after printing.
-
- jobs.c: pretty_print_job (); fflush (stream) after printing.
-
- Sat Jan 20 12:02:41 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * unwind_prot.c: run_unwind_protects_internal () -- don't
- run a non-existant function, like when the element is a
- catch frame marker.
-
- Fri Jan 19 16:57:31 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * variables.c: getenv () now calls find_tempenv_variable () first
- to find the most recent exported variable.
-
- * variables.c: find_tempenv_variable () -- new function. Makes a
- shell variable if one exists in the temporary environment for a
- command and returns that, or NULL otherwise. Used in
- set_or_show_attributes (), found in builtins.c. This specifically
- allows shell builtins to get the value of variables in the local
- environment for this command.
-
- * parse.y: pre_process_line (). Don't do any preprocessing if
- history_exapnsion_inhibited is on. builtins.c: parse_and_execute
- (). Save and restore the value of history_expansion_inhibited,
- not of history_expansion. In this way, .bashrc files can set or
- clear this flag with "set +o".
-
- Thu Jan 18 19:52:02 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * builtins.c: All builtins use builtin_error () instead of
- report_error (). All builtins have a return value.
- get_numeric_value () no longer takes FOR_WHOM argument. The value
- is now taken from THIS_COMMAND_NAME. Ditto for no_args ().
-
- * builtins.c: new function builtin_error () is similar to
- report_error (), but can never exit the shell, and uses the value
- of this_command_name in reports.
-
- Fri Jan 5 11:12:31 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * variables.c: initialize_shell_variables (). Added new variable
- HOSTTYPE which contains the machine type that this shell is
- compiled on. Also affected Makefile for additional define and
- rule for variables.c.
-
- * parse.y: pre_process_line (). In the case of ALIAS not being
- defined, a non-malloced string could be returned. Fixed by
- calling savestring (line) in that case.
-
- * execute_cmd.c: do_redirections (), do_redirect ():
- Added noclobber variable. If set redirections are
- not allowed to overwrite existing files. Also affected subst.c:
- stupidly_hack_variables.
-
- Thu Jan 4 11:51:25 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * builtins.c: pushd_builtin (), popd_builtin (). If variable
- "pushd_silent" exists don't print out new directory after cd'ing.
- Allow pushd and popd to take "-NUM" args -- they count back from
- the end of the list.
-
- Wed Jan 3 11:42:30 1990 Brian Fox (bfox at sbphy.ucsb.edu)
-
- * Gave variables two cells; one for value, one for functions.
- This modifies a large number of files. The function cell of
- a variable is addressed with "function_cell (var)"; this can be
- a LHS. The value cell is addressed with "value_cell (var)".
- There is no more att_function; you can still check to see if the
- variable has a function value with function_p (var).
-
- Mon Sep 4 18:30:33 1989 Brian Fox (bfox at aurel)
-
- * copy_command.c: copy_command (). Don't forget to copy
- the command redirections.
-
- Sun Sep 3 08:23:04 1989 Brian Fox (bfox at aurel)
-
- * readline.c: update_display (). Fixed printing of initial
- character on line twice bug.
-
- Fri Sep 1 18:52:08 1989 Brian Fox (bfox at aurel)
-
- * readline.c: rl_insert (). Optimized for large amounts
- of typeahead. Insert all insertable characters at once.
-
- * I update this too irregularly.
- Released 1.03.
-
- jobs.c: stop_pipeline (). If THE_PIPELINE is null, don't
- try to install it as a job.
-
- execute_command.c: execute_simple_command (). Fixed call
- to stop_pipeline () by adding required arguments.
-
- parse.y: yy_error (), new function report_syntax_error ().
- CASE case uses report_syntax_error ().
- shell.c: main (). If the input to the shell is a command file,
- then remember the name of the file in with_input_from_stream ().
-
- Tue Aug 8 18:11:54 1989 Brian Fox (bfox at aurel)
-
- * general.c: strindex () now placed there. Static version
- is in readline.c.
-
- * execute_cmd.c: If the shell is to read a file as commands,
- and the file appears to contain non-ascii characters, then
- complain about it being a binary file.
-
- Sun Aug 6 13:07:41 1989 Brian Fox (bfox at aurel)
-
- * unwind_prot.c: Added tag based unwind frames.
- begin_unwind_frame ("foo");
- add_unwind_protect (free, data);
- add_unwind_protect (free, data);
- ...
- run_unwind_frame ("foo");
-
- * readline.c: Added input buffer management, and event
- input.
- rl_event_hook, if non-zero, is the address of a function to
- call repeatadly while polling for input.
-
- rl_stuff_char (char) pushes CHAR onto input ring.
-
- rl_get_char (&char) (when returning non-zero) pops the front of
- the input ring, placing it into CHAR (an int).
-
- rl_gather_tyi () puts characters into input ring if available.
-
- * execute_cmd.c: execute_simple_command (): even when a function
- is being piped we need to set return_catch_flag.
-
- Sat Aug 5 08:32:05 1989 Brian Fox (bfox at aurel)
-
- * variables.c: make_var_array (), initialize_shell_variables ()
- Added exporting of functions.
-
- * read_builtin (): reads characters singly from stdin, allowing
- backslash-newline to pass.
-
- * test.c: use access () instead of opening files.
-
- * numerous files, parse_and_execute (), with_input_from...
- Added stream_name to contents of pushed and popped streams,
- and to functions that push and pop streams. yyerror () uses
- this to aid in reporting errors.
-
- Fri Aug 4 12:35:08 1989 Brian Fox (bfox at aurel)
-
- * copy_cmd.c copy_redirect (): case of r_read_until falls through
- to copy the actual here-document.
-
- Wed Aug 2 11:47:50 1989 Brian Fox (bfox at aurel)
-
- * builtins.c:cd_builtin (): if the shell variable "cdable_vars"
- exists, and the directory specified cannot be changed to, either
- first with CDPATH or directly, the the directory name is looked
- up in the list of shell variables. If it exists, and is a
- string, then that value is tried.
-
- * test.c: moved `!' operator to term () from expr ()
-
- Tue Aug 1 16:03:32 1989 Brian Fox (bfox at aurel)
-
- * execute_cmd.c, builtins.c: global variable return_catch_value
- now contains the value of `return' calls.
-
- * parse.y: current_readline_prompt gets NULL after it is freed.
-
- Sun Jul 16 07:51:46 1989 Brian Fox (bfox at aurel)
-
- * test.c: Added -S to test for file being a socket.
- builtins.c: Added documentation for -S test.
-
- * execute_cmd.c: execute_case_command ()
- The clause patterns are now expanded before being
- matched against.
-
- Tue Jul 11 05:30:58 1989 Brian Fox (bfox at aurel)
-
- * parse.y:yy_readline_get ()
- Fixed bug with readline returning EOF.
-

- Changed #ifndef NOJOBS to #ifdef JOB_CONTROL.
-
- Sat Jul 8 05:02:39 1989 Brian Fox (bfox at aurel)
-
- * parse.y
- New command type `Group' is for running commands in `{}'. This
- allows all of the commands to be piped at the same time.
-
- Wed Jun 28 16:51:42 1989 Brian Fox (bfox at aurel)
-
- * New directory: LIB contains readline and history stuff,

- ChangeLog.
-
- * history.c: removed shell dependent stuff, made into module
- in readline library.
-
- Tue Jun 27 13:05:54 1989 Brian Fox (bfox at aurel)
-
- * readline.c: removed shell dependent stuff.
-
- * New file: bashline.c contains all of the shell specific
- readline material in an attempt to begin using the
- readline stuff as a library.
-
-
- Mon Jun 26 13:35:16 1989 Brian Fox (bfox at aurel)
-
- * parse.y
- Fixed problem in read_token () which prevented '{' from
- being recognized after "c () {". Changed
- reserved_word_acceptable () to know about `{' as precursor
- to commands.
-
- * readline.c, jobs.c
- Make commands that do not complete sucessfully restore the
- tty state to whatever it was before the command was executed.
-
