Do not print trailing space at end of output. * builtins/fc.def (fc_builtin) Modify output of listed history lines to match Posix.2a specification. Sat Dec 28 16:29:28 1991 Brian Fox (bfox at gnuwest.fsf.org) * bashline.c: New functions and define for controlling their presence. The define is DYNAMIC_HISTORY_EXPANSION, and it controls whether code for completing over history tokens with M-TAB is compiled. * cpp-Makefile: Use new #define SEARCH_LIB_NEEDS_SPACE to create local Makefile variable SEARCH_LIB, which is either `-L' or `-L '. machines.h: hpux compiler requires SEARCH_LIB_NEEDS_SPACE. Sat Dec 14 12:21:17 1991 Brian Fox (bfox at gnuwest.fsf.org) * mailcheck.c; Carefully save and restore the value of $_ while hacking mail. * new file getcwd.c is included for ISC systems (or others) with broken implementations of getcwd (). * builtins/kill.def; sscanf () an integer variable and then cast the results into a pid_t. * parse.y; check shell_input_line for non-nullness before checking the contents of it.

Wed Nov 20 05:06:10 1991 Brian Fox (bfox at gnuwest.fsf.org) * parse.y: New variable CURRENT_COMMAND_LINE_COUNT controls how commands are added to the history. New function bash_add_history () handles the details of adding a line to the history. * shell.c: (parse_command) Clear current_command_line_count before calling yyparse (); * subst.c: New function and variable pair "command_oriented_history" controls behaviour of bash_add_history ().

I.e.: If a redirection fails then return a non-zero status. Else, if the command contained a command substitution then return the exit status of the command substitution. Else return a status of 0. Mon Nov 11 04:52:26 1991 Brian Fox (bfox at gnuwest.fsf.org) * machines.h: Entry for drs6000, contributed by R.S.JONES@qmw.ac.uk, Rob Jones. * test.c: (two_arguments) Disallow "test -foo" being treated as "test -f". Tue Nov 5 12:10:52 1991 Brian Fox (bfox at gnuwest.fsf.org) * Makefile, cpp-Makefile; Remove target for "clone" because it is now too hairy to support, and is largely unused. * subst.c (command_substitute); Save and restore the original pipeline process group for the making of the $() child. Mon Nov 4 00:00:39 1991 Brian Fox (bfox at gnuwest.fsf.org) * config.h: Two new defines: DISABLED_BUILTINS allows "builtin foo" to execute the shell builtin "foo" even if it has been disabled with "enable -n foo". ALLOW_RIGID_POSIX_COMPLIANCE allows the environment variable POSIX_PEDANTIC to control shell behaviour, making it a totally rigid posix compliant shell. * builtins/common.c: Rearrangement of functions and new functions. find_shell_builtin () now calls builtin_address_internal (). New function builtin_address () returns the address of a builtin whether it is enabled or not. builtin_address_internal () takes two args, NAME and DISABLED_OKAY. * support/getcppsyms.c: Add _AIX, M_UNIX, and M_XENIX to list of known defines. Sun Nov 3 23:57:05 1991 Brian Fox (bfox at gnuwest.fsf.org) * shell.c, jobs.c: Define and use top_level_mask, a signal mask for the creation of children. This fixes pipeline children being created with SIGCHLD masked. Fri Nov 1 07:07:32 1991 Brian Fox (bfox at gnuwest.fsf.org) * expr.c (evalexp) Zero token and token length before calling readtok (); * make_cmd.c (make_here_document) Inhibit <<- from deleting anything other than tab characters. * subst.c (parameter_brace_expand_length) Implement ${#xx} by actually expanding $xx instead of assuming that it is a variable. * execute_cmd.c (execute_subshell_builtin_or_function) Unwind protect and restore the return_catch jump buffer during function execution. * machines.h (ardent/titan) #undef HAVE_ALLOCA to avoid compiler bug. Wed Oct 30 12:43:54 1991 Brian Fox (bfox at gnuwest.fsf.org) * execute_cmd.c (shell_execve) Only call _setostype () if the machine is isc386, and _POSIX_SOURCE is defined. * general.c (index, rindex); Check for existence of index #define before declaring functions. * subst.c (expand_word_internal) Make ${#-} and ${#?} return the lengths of $- and $?. Mon Oct 28 11:24:31 1991 Brian Fox (bfox at gnuwest.fsf.org) * execute_cmd.c (execute_command_internal); dispose of already executed redirections when a subshell is recursively executing. * support/getcppsyms.c; All of convex, __convex__ and __convexc are translated to " -pcc -Dconvex". Thu Oct 24 14:29:24 1991 Brian Fox (bfox at gnuwest.fsf.org) * builtins/Makefile: Massage declaration of $(MKBUILTINS) to satisfy HPUX 7.0 native compiler. * builtins/type.def; Make found_file local to disk file search block.

Thu Oct 3 16:28:55 1991 Brian Fox (bfox at gnuwest.fsf.org) * parse.y (command_token_position) Now a define which calls reserved_word_acceptable (), excluding SEMI_SEMI in case clauses. * machines.h (description for ultrix && mipsel); MIPS Ultrix 4.2 machines still have alloca in the library, and it works perfectly well; the only thing to be avoided is the inclusion of alloca.h. * builtins/kill.def (kill_builtin). Allow negative signal specifiers to signify process groups. Fri Sep 6 17:34:38 1991 Brian Fox (bfox at gnuwest.fsf.org) * execute_cmd.c: (do_redirect_internal) Fix to >&- of stdout redirection bug. Minor cosmetic changes to many files. shell.h, make_cmd.c, copy_cmd.c, parse.y, Sun Jul 28 19:28:17 1991 Brian Fox (bfox at gnuwest.fsf.org) * Moved several scripts and support files into ./support. Files moved and renamed: makeargs.sh -> mksysdefs, cppmagic.sh -> cppmagic, cat-s, getcppsyms.c info, mail-shell, make-tarfile. * Moved glob/, readline/, and malloc/ (renamed from alloc-files) into a subdirectory called lib. This affected cpp-Makefile. * cpp-Makefile: Use #defines to create a macro which builds libraries, regardless of the directory that the source code resides in. Thu Jul 11 21:00:20 1991 Brian Fox (bfox at gnuwest.fsf.org) * builtins/kill.def: Make the exit status of `kill' be SUCCESS if any of the killed processes accepted the signal. * psize.c, jobs.c, shell.c, parse.y: Make signal handler functions return a value if VOID_SIGHANDLER is not defined. * parse.y, general.h, bashline.c builtins/type.def: Change token_word_alist to word_token_alist, and typedef STRING_INT_ALIST in general.h. Use the new definitions in bashline.c, builtins/type.def, and parse.y. * bashline.c: (command_word_completion_function) Complete on shell reserved words after trying aliases. Tue Jul 9 07:01:33 1991 Brian Fox (bfox at gnuwest.fsf.org) * New file maxpath.h contains the right things to define MAXPATHLEN on various systems. * (shell.h) Always include unwind_prot.h. * HUGE CHANGE. All builtins appear in builtins/*.def. There is a new program called builtins/mkbuiltins.c which is called to 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. Sun Jul 7 02:23:21 1991 Brian Fox (bfox at gnuwest.fsf.org) * builtins.c: Add `--' flag to trap, type, umask and hash builtins. * jobs.c: (set_job_control) returns the original value of job_control. Remove extra ignore of SIGQUIT. * config.h: Add define of STANDARD_UTILS_PATH for `command -p'. Add "defined" for UNIXPC where it was missing. * subst.c: make and use QUOTED_CHAR define. Test for possibilty of tilde expansion before doing it. * make_cmd.c: Only do quote_removal on here document delimiters. * builtins.c: (command_builtin) Add Posix -p flag to `command' builtin. Random textual changes to clarify the meaning of the output for various commands. exec_builtin now restores the default signal handlers. * glob.c: Avoid globbing in directories that begin with `.' if the glob pattern (and noglob_dot_filenames) don't allow it. * test.c: Avoid calling strlen () when we only care if the length is non-zero. Instead, test the first byte. * jobs.c(kill_pid) Kill the process pointed to by P, not the last one we looked at. * shell.c: Only source the .bashrc if this is not a login shell, even if we are not sourcing .bash_profile. Xenix's setvbuf () has 2 middle arguments reversed. Run the exit trap when the shell is dying from a terminating signal (like SIGINT). * general.c:(get_hostname) Change `uts' to `ut' to avoid conflict with Amdahl compiler. * execute_cmd.c:(execute_simple_command) changes to make this_shell_bultin always reflect the current command; i.e. NULL if not a builtin, otherwise, the address of the currently executing builtin. variables.c:(find_variable) Check temporary environment if current execution environment is a builtin or function. flags.h: Prevent multiple inclusion, add declarations for functions found in flags.c. Mon Jun 24 20:44:47 1991 Brian Fox (bfox at gnuwest.fsf.org) * execute_cmd.c: (do_redirections) Hack errors on variable names as redirectee's to display themselves correctly. New function expandable_redirection_filename () takes a (REDIRECT *) and returns non-zero if the redirectee should be expanded or treated as an integer. * 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. * cpp-Makefile: #undef i386 around Makefile assignments where the preprocessor might munge it. * test,c, execute_cmd.c: moved definition of group_member () into test.c from execute_cmd.c so test.c can be compiled standalone. Tue May 28 19:02:41 1991 Brian Fox (bfox at gnuwest.fsf.org) * expr.c: (evalexp) Save and restore the longjmp destination of evalbuf for each call to evalexp () to allow recursive calls to error correctly. * makeargs.sh: Fix typo for determining RISC6000. * machines.h: Fix bugs in machine descriptions according to bug reports. * execute_cmd.c: (execute_simple_command) Remove all of the execve code and shell interpretation code placing it into a new function called shell_execve (). * builtins.c (exec_builtin) call shell_execve () instead of execve (). * Makefile: Add $(STRERROR) to flags. Fri May 24 12:05:45 1991 Brian Fox (bfox at gnuwest.fsf.org) * cpp-Makefile: Pass AR to library builds, same as RANLIB. * general.c: Move definitions of index () and rindex () to top of 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 while completing along PATH. This may be obsoleted in the near future, since we might do rms's `=~' and `:~' expansion hacks. * all files: Remove extraneous tab characters in comments. * Makefile: Change rules for SQUASH_BLANKS; default to using awk script. * cat-s: New awk script file added to distribution. Thu May 23 17:56:35 1991 Brian Fox (bfox at gnuwest.fsf.org) * machines.h: Default to USE_GNU_MALLOC and HAVE_DUP2. Turn off USE_GNU_MALLOC for Sun workstations because of YP bug in Sun. cpp-Makefile: Add -DHAVE_DUP2 to CFLAGS if you have it. Add -DHAVE_ALLOCA to cflags if you have it, so config.h gets it. * test.c: (two_arguments) Fix typo in call to unop (). (posixtest) Add missing `break' for 4 argument case. Wed May 22 15:02:31 1991 Brian Fox (bfox at gnuwest.fsf.org) * shell.c: (maybe_save_history): add a call to using_history () before checking history_lines_this_session. Sun May 19 17:47:15 1991 Brian Fox (bfox at gnuwest.fsf.org) * 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 to go to. This is for arithmetic and bad substitution errors. * builtins.c: (hash_builtin) use absolute_program () instead of absolute_pathname (). * cpp-Makefile: Numerous changes include using cpp defines for readline and termcap targets for those `make' programs which don't correctly handle variable expansion in the target postion, .distribution now depends on version.h, `make clean' now removes created support files. substantial reorganization. Pass $(RANLIB) to library building makes. * builtins.c (builtin_error) Only print this_command_name if it is 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. * jobs.h: HP/UX systems barf on WIF* macros in sys/wait.h. Use our definitions in jobs.h instead. * machines.h: Numerous changes. Compiler flags for MIPS. Improved Encore machines. * makeargs.sh: Better tests for whoami and hostname. * nojobs.c: Changes to allow compilation on MINIX and BSD without job control. * parse.y: Discard null input characters. Properly count parens and quotes inside of $() and $[]. subst.c:(extract_delimited_string) also counts correctly. * posixstat.h: More definitions and fewer assumptions about the 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. subst.c: Separate out command substitution from the the main loop. (string_extract_double_quoted) now allows new quoting rules from Posix.2. * test.c: test -f behaviour now rigidly Posix.2 compliant. Thu Feb 21 19:54:29 1991 Brian Fox (bfox at gnuwest.fsf.org) * jobs.c: Merged in changes to call POSIX signal functions. Added declarations to make those functions work on non-POSIX systems. 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: foo{ -> no error foo{a, -> error foo{} -> no error foo} -> no error 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 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 * jobs.c (execute_command_internal) allow the output of `jobs' to be piped. Tue May 15 02:24:30 1990 Brian Fox (bfox at gnuwest.fsf.org) * builtins.c (set_builtin) fixed type in call to strcmp (). 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. * All files 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, and is Make-able on its own. Also contains its own 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.
