|
|
blarney, but now it does.
|
|
|
|
* builtins/echo.def: (echo_builtin) Document -E flag. Check
|
|
option strings for full validity before handling any of the

|
|
|
|
* machines.h, shell.c: Instead of Xenix being the #define which

a new define (added to SYSDEP_CFLAGS for Xenix machines) called
|
|
REVERSED_SETVBUF_ARGS.
|
|
|
|
* cpp-Makefile: Quote values of AR and RANLIB passed to sub makes.

|
|
|
|
Thu Nov 14 04:23:08 1991 Brian Fox (bfox at gnuwest.fsf.org)
|
|
|
|
* builtins/shift.def; The shift count can be zero.

|
|
|
* 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

|
|
two args, NAME and DISABLED_OKAY.

|
|
|
|
* 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)

|
|
|
|
* support/getcppsyms.c; All of convex, __convex__ and __convexc
|
|
are translated to " -pcc -Dconvex".

|
|
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.
|
|
|
|

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)
|
|

|
|
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.
|

|
glob pattern (and noglob_dot_filenames) don't allow it.
|
|
|

|
|
is non-zero. Instead, test the first byte.
|

|
|
one we looked at.
|
|
|
|

|
|
even if we are not sourcing .bash_profile.
|

|
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
|

|
|
|
|
* execute_cmd.c: (do_redirections) Hack errors on variable names
|
|
as redirectee's to display themselves correctly. New function

|
|
as an integer.
|
|

|
|
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.
|
|

|
|
|

* 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

|
|
(display_shell_version) outputs carriage return after printing the

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.
|
|

|
|
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 <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
|
|
|
|
* 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
|
|
