Raw Blame History

2/14/2011
---------
[bash-4.2 released]
2/15
----
lib/glob/gmisc.c
- fix wmatchlen and umatchlen to avoid going past the end of the
string on an incomplete bracket expression that ends with a
NUL. Partial fix for bug reported by Clark Wang <dearvoid@gmail.com>
2/16
----
subst.h
- new string extract flag value: SX_WORD. Used when calling
extract_dollar_brace_string to skip over the word in
${param op word} from parameter_brace_expand
subst.c
- change parameter_brace_expand to add SX_WORD to flags passed to
extract_dollar_brace_string
- change parameter_brace_expand to use SX_POSIXEXP for all non-posix
word expansion operators that treat single quotes as special, not
just % and #
- change extract_dollar_brace_string to initialize dolbrace_state to
DOLBRACE_WORD if SX_WORD flag supplied and we shouldn't use
DOLBRACE_QUOTE. Fixes bug reported by Juergen Daubert <jue@jue.li>
doc/{bash.1,bashref.texi}
- document the exact expansions here strings undergo
2/17
----
lib/readline/vi_mode.c
- make sure that `dd', `cc', and `yy' call vidomove_dispatch from
rl_domove_read_callback. Fixes bug reported by Clark Wang
<dearvoid@gmail.com>
lib/readline/callback.c
- make sure _rl_internal_char_cleanup is called after the
vi-motion callbacks (rl_vi_domove_callback) in rl_callback_read_char.
Companion to above fix
doc/{bash.1,bashref.texi}
- make sure that the text describing the rhs of the == and =~
operators to [[ states that only the quoted portion of the pattern
is matched as a string
2/18
----
lib/glob/gmisc.c
- better fix for umatchlen/wmatchlen: keep track of the number of
characters in a bracket expression as the value to increase
matchlen by if the bracket expression is not well-formed. Fixes
bug reported by Clark Wang <dearvoid@gmail.com>
subst.c
- change expand_string_for_rhs so that it sets the W_NOSPLIT2 flag
in the word flags. We will not perform word splitting or quote
removal on the result, so we do not want to add quoted nulls if
we see "" or ''. Fixes bug reported by Mike Frysinger
<vapier@gentoo.org>
2/19
----
variables.c
- new function, int chkexport(name), checks whether variable NAME is
exported and remakes the export environment if necessary. Returns
1 if NAME is exported and 0 if not
- call chkexport(name) to get tzset to look at the right variable in
the environment when modifying TZ in sv_tz. Don't call tzset if
chkexport doesn't indicate that the variable is exported
variables.h
- new extern declaration for chkexport
{parse.y,builtins/printf.def}
- call sv_tz before calling localtime() when formatting time strings
in prompt strings or using printf. Fixes bug reported by
Dennis Williamson <dennistwilliamson@gmail.com>
execute_cmd.c
- modify fix of 2/9 to add casts when those variables are passed to
functions; some compilers throw errors instead of warnings. Report
and fix from Joachim Schmitz <jojo@schmitz-digital.de>
support/shobj-conf
- add a stanza for nsk on the Tandem from Joachim Schmitz
<jojo@schmitz-digital.de>
{shell,lib/readline/shell}.c
- Tandem systems should use getpwnam (getlogin()); for some reason
they don't do well with using getuid(). Fix from Joachim Schmitz
<jojo@schmitz-digital.de>
3/1
---
variables.c
- make sure that the return value from find_variable is non-null
before trying to use it in chkexport. Fixes bug reported by
Evangelos Foutras <foutrelis@gmail.com>
3/3
---
parse.y
- when adding $$ to the current token buffer in read_token_word(),
don't xmalloc a buffer for two characters and then strcpy it, just
copy the characters directly into the token buffer. Fix from
Michael Whitten <mfwitten@gmail.com>
execute_cmd.c
- fix expand_word_unsplit to add the W_NOSPLIT2 flag to the word to
be expanded, so "" doesn't add CTLNUL. Similar to fix of 2/18 to
expand_string_for_rhs. Fixes bug reported by Nathanael D. Noblet
<nathanael@gnat.ca> and Matthias Klose <doko@debian.org>
parse.y
- fix extended_glob case of read_token_word to allocate an extra
space in the buffer for the next character read after the extended
glob specification if it's a CTLESC or CTLNUL. Report and fix from
Michael Witten <mfwitten@gmail.com>
- fix shell expansions case of read_token_word to allocate an extra
space in the buffer for the next character read after the shell
expansion if it's a CTLESC or CTLNUL. Report and fix from
Michael Witten <mfwitten@gmail.com>
- TENTATIVE: fix read_token_word to reduce the amount of buffer space
required to hold the translated and double-quoted value of $"..."
strings. Report and fix from Michael Witten <mfwitten@gmail.com>
- change code around got_character and got_escaped_character labels to
make sure that we call RESIZE_MALLOCED_BUFFER before adding the
CTLESC before a CTLESC or CTLNUL, and before adding the character if
we're not adding a CTLESC. Report and fix from
Michael Witten <mfwitten@gmail.com>
subst.c
- new param flags value, PF_ASSIGNRHS, mirrors W_ASSIGNRHS, noting that
parameter expansion is on rhs of assignment statement. That inhibits
word splitting
- change param_expand to call string_list_dollar_at with quoted == 1
if PF_ASSIGNRHS is set, so it will quote IFS characters in the
positional parameter before separating them with the first char of
$IFS. This keeps the rhs from being split inappropriately. Fixes
bug reported by Andres Perera <andres.p@zoho.com>
3/4
---
lib/readline/bind.c
- add a missing free of `names' in rl_function_dumper. Bug report
and fix from Michael Snyder <msnyder@vmware.com>
3/5
---
lib/readline/rltty.c
- change rl_deprep_terminal so it uses fileno (stdin) for the tty fd
if rl_instream is not set, like rl_prep_terminal
3/6
---
lib/readline/display.c
- fix rl_message to use a dynamically-allocated buffer instead of a
fixed-size buffer of 128 chars for the `local message prompt'. Bug
report and fix from Micah Cowan <micah@cowan.name>
3/7
---
jobs.c
- add sentinel to wait_sigint_handler so it only sets wait_sigint_received
if waiting_for_child is non-zero; otherwise, it restores the old
SIGINT handler and sends itself the SIGINT
- set waiting_for_child around the calls to waitchld that use it to
synchronously wait for a process
- change logic that decides whether or not the child process blocked
or handled SIGINT based on whether or not waitpid returns -1/EINTR
and the shell receives a SIGINT and the child does not exit. If
the child later exits due to SIGINT, cancel the assumoption that it
was handled
- instead of testing whether or not the child exited due to SIGINT
when deciding whether the shell should act on a SIGINT it received
while waiting, test whether or not we think the child caught
SIGINT. If it did, we let it go (unless the shell has it trapped);
if it did not catch it, the shell acts on the SIGINT. Fix from
Linus Torvalds <torvalds@linux-foundation.org>, bug report originally
from Oleg Nesterov <oleg@redhat.com>
3/8
---
shell.c
- initialize no_line_editing to 1 if READLINE is not defined -- we
can't have line editing without readline
3/12
----
lib/readline/signals.c
- add SIGHUP to the set of signals readline handles
lib/readline/doc/rltech.texi
- document that SIGHUP is now part of the set of signals readline
handles
lib/readline/input.c
- if _rl_caught_signal indicates that read() was interrupted by a
SIGHUP or SIGTERM, return READERR or EOF as appropriate
- call rl_event_hook, if it's set, if call to read in rl_getc
returns -1/EINTR. If rl_event_hook doesn't do anything, this
continues the loop as before. This handles the other fatal
signals
execute_cmd.c
- add a couple of QUIT; calls to execute_disk_command and
execute_simple_command to improve responsiveness to interrupts
and fatal signals
input.c
- rearrange getc_with_restart so that the return values from read()
are handled right
parse.y
- don't need to set terminate_immediately in yy_stream_get, since
getc_with_restart checks for terminating signals itself
- since readline returns READERR on SIGHUP or SIGTERM, don't need
to set terminate_immediately. Still doesn't handle other
signals well -- will have to check that some more
bashline.c
- new function, bash_event_hook, for rl_event_hook. Just checks for
terminating signals and acts on them using CHECK_TERMSIG.
- set rl_event_hook to bash_event_hook
builtins/read.def
- take out setting terminate_immediately; add calls to CHECK_TERMSIG
after read calls
doc/{bash.1,bashref.texi}
- move the text describing the effect of negative subscripts used to
reference indexed array elements to the paragraphs describing
${parameter[subscript]}, since that's where they are implemented.
Pointed out by Christopher F. A. Johnson <cfajohnson@gmail.com>
arrayfunc.[ch],subst.c
- array_expand_index now takes a new first argument: a SHELL_VAR *
of the array variable being subscripted. Can be used later to fully
implement negative subscripts
3/14
----
lib/glob/glob.c
- fix mbskipname to not turn the directory entry name into a wide char
string if the conversion of the pattern to a wide char string fails
- fix mbskipname to call skipname if either the pattern or the filename
can't be converted into a wide-char string
lib/glob/xmbsrtowcs.c
- fix xdupmbstowcs2 to handle return value of 0 from mbsnrtowcs and
short-circuit with failure in that case. Fixes bug reported by
Roman Rakus <rrakus@redhat.com>
3/15
----
bashline.c
- new variable, bash_filename_quote_characters to store the value
assigned to rl_filename_quote_characters so it can be restored
if changed.
- change bashline_reset and attempt_shell_completion to restore
rl_filename_quote_characters if not set to default
3/22
----
lib/glob/glob.c
- wdequote_pathname falls back to udequote_pathname if xdupmbstowcs
fails to convert the pathname to a wide-character string
lib/glob/xmbsrtowcs.c
- xdupmbstowcs2: change to fix problem with leading '\\' (results in
nms == 0, which causes it to short-circuit with failure right
away). Fixes bug pointed out by Werner Fink <werner@suse.de>
- xdupmbstowcs2: compensate for mbsnrtowcs returning 0 by taking the
next single-byte character and going on
- xdupmbstowcs2: change memory allocation to increase by WSBUF_INC
bytes; try to avoid calls to realloc (even if they don't actually
result in more memory being allocated)
3/24
----
doc/{bash.1,bashref.texi}
- slightly modify BASH_SUBSHELL description based on complaint from
Sam Liddicott <sam@liddicott.com>
3/25
----
trap.c
- change free_trap_strings to not call free_trap_string for signals
that are being ignored, like reset_or_restore_signal_handlers.
Fixes bug reported by Satoshi Takahashi <blue3waters@gmail.com>
3/26
----
lib/readline/rltypedefs.h
- remove old Function/VFunction/CPFunction/CPPFunction typedefs as
suggested by Tom Tromey <tromey@redhat.com>
lib/readline/rlstdc.h
- move defines for USE_VARARGS/PREFER_STDARG/PREFER_VARARGS from
config.h.in to here because declaration of rl_message in
readline.h uses the defines. This makes it hard for another packages
to use after the header files are installed, since config.h is not
one of the installed files. Suggested by Tom Tromey
<tromey@redhat.com>
3/27
----
print_cmd.c
- change indirection_string from a static buffer to a dynamic one
managed by indirection_level_string(), so we don't end up truncating
PS4. Suggested by Dennis Williamson <dennistwilliamson@gmail.com>
lib/readline/shell.c
- change sh_set_lines_and_columns to use static buffers instead of
allocating the buffers to pass to setenv/putenv
lib/readline/terminal.c
- change _rl_get_screen_size to not call sh_set_lines_and_columns if
ignore_env == 0
- _rl_sigwinch_resize_terminal: new function to just retrieve terminal
size, ignoring environment
lib/readline/rlprivate.h
- new external declaration for _rl_sigwinch_resize_terminal() (currently
unused)
lib/readline/signals.c
- rl_sigwinch_handler: set _rl_caught_signal to SIGWINCH
- rl_sigwinch_handler: don't immediately call rl_resize_terminal; just
leave _rl_caught_signal set for RL_CHECK_SIGNALS to handle
- _rl_signal_handler: call rl_resize_terminal if sig == SIGWINCH.
Should fix hang when sending multiple repeated SIGWINCH reported by
Henning Bekel <h.bekel@googlemail.com>
3/29
----
lib/sh/snprintf.c
- include math.h for any defines for isinf/isnan
- use code from gnulib documentation to implement isinf/isnan if they
are not defined
configure.in
- don't check for isinf or isnan; c99 says they're macros anyway
config.h.in
- remove defines for ISINF_IN_LIBC and ISNAN_IN_LIBC, no longer used
by snprintf.c
4/2
---
braces.c
- brace_gobbler: fix to understand double-quoted command substitution,
since the shell understands unquoted comsubs. Fixes bug reported
by Michael Whitten <mfwitten@gmail.com>
lib/readline/display.c
- include <pc.h> on MDOS
- get and set screen size using DJGPP-specific calls on MSDOS
- move cursor up clear screen using DJGPP-specific calls
- don't call tputs on DJGPP; there is no good terminfo support
lib/readline/terminal.c
- include <pc.h> on MDOS
- get and set screen size using DJGPP-specific calls on MSDOS
- use DJGPP-specific initialization on MSDOS, zeroing all the
_rl_term_* variables
- don't call tputs on DJGPP; there is no good terminfo support
DJGPP support from Eli Zaretskii <eliz@gnu.org>
4/6
---
config-top.h
- change DEFAULT_PATH_VALUE to something more useful and modern
4/8
---
tests/printf2.sub
- make sure LC_ALL and LC_CTYPE are set so LANG assignment takes effect.
Reported by Cedric Arbogast <arbogast.cedric@gmail.com>
4/11
----
include/chartypes.h
- fix a couple of dicey defines (though ones that don't cause any
compiler warnings) in IN_CTYPE_DOMAIN
doc/{bashref.texi,bash.1}
- add note referring to duplicating file descriptors in sections
describing redirecting stdout and stderr and appending to stdout
and stderr. Suggested by Matthew Dinger <mdinger.bugzilla@gmail.com>
pcomplete.c
- it_init_helptopics: new function to support completing on help topics,
not just builtins
- it_helptopics: new programmable completion list of help topics
- build list of helptopic completions in gen_action_completions on
demand
pcomplete.h
- new extern declaration for it_helptopics
builtins/complete.def
- the `helptopic' action now maps to CA_HELPTOPIC intead of CA_BUILTIN,
since there are more help topics than just builtins. Suggested by
Clark Wang <dearvoid@gmail.com>
4/12
----
print_cmd.c
- fix print_arith_for_command to add a call to PRINT_DEFERRED_HEREDOCS
before ending the body of the command, so heredocs get attached to
the right command instead of to the loop. From gentoo bug 363371
http://bugs.gentoo.org/show_bug.cgi?id=363371
execute_cmd.c
- change coproc_pidchk to unset the appropriate shell variables when
the (currently single) known coproc pid terminates
- cleanup and new functions to fully support multiple coprocesses when
and if I decide to go there
4/13
----
print_cmd.c
- fix print_group_command to add a call to PRINT_DEFERRED_HEREDOCS
after call to make_command_string_internal before printing closing
`}'
- fix make_command_string_internal to add a call to
PRINT_DEFERRED_HEREDOCS after recursive call to
make_command_string_internal in case cm_subshell before printing
closing `)'
4/14
----
print_cmd.c
- change overlapping strcpy in named_function_string to memmove
sig.h
- UNBLOCK_SIGNAL: convenience define, same as UNBLOCK_CHILD, just
restores an old signal mask
trap.c
- set_signal: instead of setting the signal handler to SIG_IGN while
installing the new trap handler, block the signal and unblock it
after the new handler is installed. Fixes bug reported by Roman
Rakus <rrakus@redhat.com>
4/15
----
doc/{bash.1,bashref.texi}
- make it clear that enabling monitor mode means that all jobs run in
separate process groups
4/18
----
builtins/fc.def
- update fix of 4/15/2010 to not take saved_command_line_count into
account when stepping down the history list to make sure that
last_hist indexes something that is valid. Fixes bug reported by
<piuma@piumalab.org>
4/19
----
builtins/fc.def
- fc_gethnum: make sure the calculation to decide the last history
entry is exactly the same as fc_builtin. Fixes bug uncovered by
fix of 4/18 to stop seg fault
4/22
----
lib/readline/terminal.c
- change _rl_enable_meta_key to set a flag indicating that it sent the
enable-meta sequence
- _rl_disable_meta_key: new function to turn off meta mode after we
turned it on with _rl_enable_meta_key
lib/readline/rlprivate.h
- extern declaration for _rl_disable_meta_key
configure.in
- if not cross-compiling, set CFLAGS_FOR_BUILD from any CFLAGS inherited
from the environment. Fixes HP/UX build problem reported by
"Daniel Richard G." <skunk@iSKUNK.ORG>
4/26
----
config-top.h
- define MULTIPLE_COPROCS to 0 so the code is still disabled but easy
to enable via configure option or editing this file
4/29
----
lib/sh/eaccess.c
- freebsd provides faccessat, with the same misfeature as their eaccess
and access implementations (X_OK returns true for uid==0 regardless
of the actual file permissions), so reorganize code to check the
file permissions as with eaccess. Report and fix from Johan Hattne
<johan.hattne@utsouthwestern.edu>
5/2
---
doc/{bash.1,bashref.texi}
- add forward reference to `Pattern Matching' from `Pathname
Expansion', suggested by Greg Wooledge <wooledg@eeg.ccf.org>
5/5
---
pcomplib.c
- the bash_completion project now distributes over 200 completions
for various programs, with no end in sight, so increase the value
of COMPLETE_HASH_BUCKETS from 32 to 128
pathexp.c
- quote_string_for_globbing: make sure CTLESC quoting CTLESC is
translated into \<CTLESC> even if the flags include QGLOB_REGEXP.
We don't want to process the second CTLESC as a quote character.
Fixes bug reported by Shawn Bohrer <sbohrer@rgmadvisors.com>
5/6
---
builtins/printf.def
- change PRETURN to not call fflush if ferror(stdout) is true
- if a call to one of the stdio functions or printstr leaves
ferror(stdout) true, and PRETURN is going to be called, let PRETURN
print the error message rather than doubling up the messages. Fixes
problem reported by Roman Rakus <rrakus@redhat.com>
5/9
---
doc/{bash.1,bashref.texi}
- add note to the effect that lists inside compound command can be
terminated by newlines as well as semicolons. Suggested by
Roman Byshko <rbyshko@gmail.com>
5/10
----
subst.c
- remove_quoted_nulls: fix problem that caused it to skip over the
character after a CTLNUL, which had the effect of skipping every
other of a series of CTLNULs. Fixes bug reported by
Marten Wikstrom <marten.wikstrom@keystream.se>
5/11
----
subst.c
- extract_process_subst: add SX_COMMAND flag to call to
extract_delimited_string, since we're expanding the same sort of
command as command substitution. Fixes bug reported in Ubuntu
bug 779848
5/12
----
configure.in
- set the prefer_shared and prefer_static variables appropriately
depending on the value of $opt_static_link
aclocal.m4
- AC_LIB_LINKFLAGS_BODY: change to not prefer shared versions of the
libraries it's searching for if the prefer_shared variable is "no".
Fixes problem reported by Cedric Arbogast <arbogast.cedric@gmail.com>
5/13
----
lib/readline/readline.c
- _rl_internal_teardown: add call to _rl_disable_meta_key to make the
meta key active only for the duration of the call to readline()
- _rl_internal_setup: move call to _rl_enable_meta_key here from
readline_initialize_everything so the meta key is active only for
the duration of the call to readline(). Suggestion from Miroslav
Lichvar <mlichvar@redhat.com>
builtins/help.def
- help_builtin: change strncmp to strcmp so that `help read' no longer
matches `readonly'. Suggested by Clark Wang <dearvoid@gmail.com>
config.h.in
- add define for GLIBC21, checked using jm_GLIBC21 as part of the tests
for libintl
lib/malloc/malloc.c
- internal_free: don't use the cached value of memtop when deciding
whether or not to adjust the break and give memory back to the kernel
when using the GNU C library, since glibc uses sbrk for its own
internal purposes. From Debian bug 614815, reported by Samuel
Thibault <samuel.thibault@gnu.org>
aclocal.m4
- BASH_STRUCT_WEXITSTATUS_OFFSET: change AC_RUN_IFELSE to AC_TRY_RUN
to avoid warning about not using AC_LANG_SOURCE
5/14
----
bashline.[ch]
- two new functions, bashline_set_event_hook and bashline_reset_event_hook,
to set rl_event_hook to bash_event_hook and back to NULL, respectively
- don't set rl_event_hook unconditionally
sig.c
- termsig_sighandler: if the shell is currently interactive and
readline is active, call bashline_set_event_hook to cause
termsig_handler to be called via bash_event_hook when the shell
returns from the signal handler
5/15
----
lib/readline/display.c
- _rl_col_width: Mac OS X has a bug in wcwidth: it does not return 0
for UTF-8 combining characters. Added workaround dependent on
MACOSX. Fixes problem pointed out by Thomas De Contes
<d.l.tDecontes@free.fr>
5/16
----
lib/readline/rlmbutil.h
- WCWIDTH: wrapper for wcwidth that returns 0 for Unicode combining
characters on systems where wcwidth is broken (e.g., Mac OS X).
lib/readline/{complete,display,mbutil}.c
- use WCWIDTH instead of wcwidth
5/17
----
lib/readline/display.c
- update_line: after computing ofd and nfd, see whether the next
character in ofd is a zero-width combining character. If it is,
back ofd and nfd up one, so the base characters no longer compare
as equivalent. Fixes problem reported by Keith Winstein
<keithw@mit.edu>
lib/readline/nls.c
- _rl_utf8locale: new flag variable, set to non-zero if the current
locale is UTF-8
- utf8locale(): new function, returns 1 if the passed lspec (or the
current locale) indicates that the locale is UTF-8. Called from
_rl_init_eightbit
lib/readline/rlprivate.h
- extern declaration for _rl_utf8locale
locale.c
- locale_utf8locale: new flag variable, set to non-zero if the current
locale is UTF-8 (currently unused)
- locale_isutf8(): new function, returns 1 if the passed lspec (or the
current locale) indicates that the locale is UTF-8. Should be called
whenever the locale or LC_CTYPE value is modified
aclocal.m4
- BASH_WCWIDTH_BROKEN: new test for whether or not wcwidth returns
zero-width characters like unicode combining characters as having
display length 1; define WCWIDTH_BROKEN in this case
config.h.in
- WCWIDTH_BROKEN: new define
lib/readline/rlmbutil.h
- change WCWIDTH macro to use _rl_utf8locale and the full range of
Unicode combining characters (U+0300-U+036F)
5/19
----
lib/readline/rlprivate.h
- _rl_search_context: new member, prevc, will hold character read
prior to lastc
lib/readline/isearch.c
- _rl_isearch_dispatch: if the character causes us to index into
another keymap, save that character in cxt->prevc
- _rl_isearch_dispatch: if we index into another keymap, but don't
find a function that's special to i-search, and the character that
caused us to index into that keymap would have terminated the
search, push back cxt->prevc and cxt->lastc to make it appear as
if `prevc' terminated the search, and execute lastc as a command.
We have to push prevc back so we index into the same keymap before
we read lastc. Fixes bug report from Davor Cubranic
<cubranic@stat.ubc.ca>
5/20
----
expr.c
- expr_bind_variable: pay attention to the return value from
bind_variable and check whether or not we should error out due to
a readonly or noassign variable. Fixes bug reported by Eric
Blake <eblake@redhat.com>
5/26
----
lib/readline/search.c
- include histlib.h for ANCHORED_SEARCH defines
- rl_history_search_flags: new variable, holds ANCHORED_SEARCH flag for
the duration of a history search
- rl_history_search_reinit: takes a new flags variable, defines whether
or not the search is anchored; assigned to rl_history_search_flags
- rl_history_serarch_reinit: if ANCHORED_SEARCH flag passed, add ^ to
beginning of search string; otherwise search string is unmodified
- rl_history_search_internal: set rl_point appropriately based on
whether or not rl_history_search_flags includes ANCHORED_SEARCH
- rl_history_substr_search_forward: new function, for non-anchored
substring search forward through history for string of characters
preceding rl_point
- rl_history_substr_search_backward: new function, for non-anchored
substring search backward through history for string of characters
preceding rl_point. Original code from Niraj Kulkarni
<kulkarniniraj14@gmail.com>
lib/readline/readline.h
- extern declarations for rl_history_substr_search_{for,back}ward
lib/readline/funmap.c
- history-substring-search-forward: new bindable command, invokes
rl_history_substr_search_forward
- history-substring-search-backward: new bindable command, invokes
rl_history_substr_search_backward
lib/readline/doc/{rluser.texi,readline.3}
- document history-substring-search-forward and
history-substring-search-backward
5/27
----
{nojobs,jobs}.c
- add support for DONT_REPORT_SIGTERM so that the shell doesn't print
a message when a job exits due to SIGTERM since that's the default
signal sent by the kill builtin. Suggested by Marc Herbert
<mark.herbert@gmail.com>
config-top.h
- DONT_REPORT_SIGTERM: new user-modifiable setting. Commented out
by default
5/28
----
lib/readline/bind.c
- _rl_skip_to_delim: skip to a closing double quote or other delimiter,
allowing backslash to quote any character, including the delimiter
- rl_parse_and_bind: call _rl_skip_to_delim instead of using inline
code
- rl_parse_and_bind: allow quoted strings as the values of string
variables. Variable values without double quotes have trailing
whitespace removed (which still allows embedded whitespace, for

- expand_compound_array_assignment: defer expansion of words between
parens when performing compound assignmnt to an associative array
variable
- assign_compound_array_list: perform the same expansions when doing
a compound array assignment to an associative array variable as
when doing a straight array index assignment. The idea is that
foo=( [ind1]=bar [ind2]=quux)

called when the application is active (e.g., between the calls to
rl_callback_handler_install and rl_callback_read_char). If the
readline signal handlers only set a flag, which the application
doesn't know about, the signals will effectively be ignored until

filename completion is desired, and rl_filename_stat_hook points
to a function, call that function to expand the filename in an
application-specific way before calling stat.
bashline.c
- bash_default_completion: if variable completion returns a single
match, use bash_filename_stat_hook and file_isdir to determine
whether or not the variable name expands to a directory. If it
does, set the filename_append_character to `/'. This is not
perfect, so we will see how it works out. Adds functionality
requested by Peter Toft <pto@linuxbog.dk> and Patrick Pfeifer
<patrick@pfeifer.de>
- rl_filename_stat_hook: assigned bash_filename_stat_hook, so things
like $HOME/Downloads (after completion) have a slash appended.

builtins/set.def
- if neither -f nor -v supplied, don't allow a readonly function to
be implicitly unset. Fixes bug reported by Jens Schmidt

lib/readline/callback.c
- change CALLBACK_READ_RETURN to clear signal handlers before returning

installed when readline doesn't have control. Idea from Jan
Kratochvil <jan.ktratochvil@redhat.com> and the GDB development
team

pathexp.c
- quote_string_for_globbing: if QGLOB_REGEXP, make sure characters
between brackets in an ERE bracket expression are not inappropriately
quoted with backslashes. This is a pretty substantial change,
should be stressed when opening bash up for alpha and beta tests.
Fixes bug pointed out by Stephane Chazleas
<stephane_chazelas@yahoo.fr>
doc/{bash.1,bashref.texi}
- document that regexp matches can be inconsistent when quoting
characters in bracket expressions, since usual quoting characters
lose their meaning within brackets
- note that regular expression matching when the pattern is stored
in a shell variable which is quoted for expansion causes string
matching
redir.h
- RX_SAVEFD: new flag value; notes that a redirection denotes an
fd used to save another even if it's not >= SHELL_FD_BASE
redir.c
- do_redirection_internal: when deciding whether or not to reset the
close-on-exec flag on a restored file descriptor, trust the value
of redirect->flags & RX_SAVCLEXEC even if the fd is < SHELL_FD_BASE
if the RX_SAVEFD flag is set
- add_undo_redirect: set the RX_SAVEFD flag if the file descriptor
limit is such that the shell can't duplicate to a file descriptor
>= 10. Fixes a limitation that tripped a coreutils test reported
by Paul Eggert <eggert@cs.ucla.edu>

doc/bash.1,lib/readline/doc/{rluser.texi,readline.3}
- keyseq-timeout: documented
lib/readline/isearch.c
- _rl_isearch_dispatch: modification to fix from 7/18 to not use
cxt->keymap and cxt->okeymap, since by the time this code is
executed, they are equal. Use `f' to check for rl_insert or
unbound func
- _rl_isearch_dispatch: if we're switching keymaps, not in
callback mode, and don't have pending or pushed input, use
_rl_input_queued to resolve a potentially ambiguous key sequence.
Suggested by Roger Zauner <rogerx.oss@gmail.com>
- _rl_isearch_dispatch: if we have changed keymaps and resolved to
an editing function (not self-insert), make sure we stuff the
right characters back onto the input after changing the keymap
back so the right editing function is executed after the search
is terminated. Rest of fix for bug reported by Roger Zauner

builtins/gen-helpfiles.c
- new file: reads struct builtin and writes the long docs to files
in the `helpdirs' subdirectory. The filename is given in the
previously-unused `handle' member of the struct builtin. Links
with `tmpbuiltins.o', which is created by Makefile to have the
right long documentation. When not cross-compiling, gets the
right #defines based on configuration options from config.h instead
of trying to parse conditional parts of def files. Fixes
shortcoming pointed out by Andreas Schwab <schwab@linux-m68k.org>
builtins/Makefile.in
- tmpbuiltins.c: new generated file, created to enable creation of
separate helpfiles based on correct #defines instead of trying to
parse conditional parts of def files

tmpbuiltins.o
- HELPFILES_TARGET: new target, substituted by configure to `helpdoc'
if separate helpfiles requested

- CREATED_OBJECTS: new variable, holds created object files for
make clean; changed make clean to remove created objects
- helpdoc: changed to call gen-helpfiles instead of mkbuiltins
Makefile.in
- when building libbuiltins.a, recursively call make with `targets'
argument to make sure separate helpfiles get built
configure.in
- substitute `helpdoc' as value of HELPFILES_TARGET if
--enable-separate-helpfiles supplied as configure argument
builtins/mkbuiltins.c
- `-nofunctions': new argument, causes mkbuiltins to not write value
for function implementing a particular builtin to struct builtin

(which uses zread internally)
builtins/read.def
- read_builtin: don't set interrupt_immediately before calling zread

CHECK_TERMSIG to check for terminating signals
- wait_sigint_handler: don't longjmp out of the wait builtin unless
interrupt_immediately is set; otherwise just SIGRETURN from the
handler
- wait_sigint_handler: if interrupt_immediately not set, but we are
executing in the wait builtin and SIGINT is not trapped, treat it
as a `normally received' SIGINT: restore the signal handler and
send SIGINT to ourselves
- waitchld: when in posix mode and running SIGCHLD traps, don't longjmp
to wait_intr_buf (and let wait be interrupted) if we're running from
a signal handler. Wait for CHECK_WAIT_INTR to do the longjmp.
run_pending_traps will run the SIGCHLD trap later
nojobs.c
- reap_zombie_children, wait_for_single_pid, wait_for: call
CHECK_WAIT_INTR where we call CHECK_TERMSIG

redir.c
- redirection_expand, write_here_string, write_here_document: before
calling any of the word expansion functions, after setting
expanding_redir to 1 (which bypasses the temp environment in the
variable lookup functions), call sv_ifs to reset the cached IFS-
related variables set by subst.c:setifs(). This ensures that
redirections will not get any IFS values that are set in the
temporary environment, as Posix specifies. Then, after the word
expansions, after resetting expanding_redir to 0, call sv_ifs
again to make sure the cached IFS values are set from any
assignments in the temporary environment. We force executing_builtin
to 1 to `fool' the variable lookup functions into using any temp
environment, then reset it to its old value after sv_ifs returns.
This is what allows read() to use the (cached) IFS variables set
in the temp environment. Fixes inconsistency reported by Dan Douglas

subst.c
- parameter_brace_expand: make sure to propagate the PF_ASSIGNRHS flag
to parameter_brace_expand_word
- parameter_brace_expand_word: make sure that if the PF_ASSIGNRHS flag
is set and we are expanding ${a[@]} or ${a[*]} we set quoted to
include Q_DOUBLE_QUOTES before calling array_value_internal, mirroring
what we do for $@ and $*. Fixes inconsistency reported by Dan
Douglas <ormaaj@gmail.com>
configure.ac
- use AC_CHECK_TOOL instead of AC_CHECK_PROG to check for ar, since it
will find $host-prefixed versions of utilities. Report and fix from
Mike Frysinger <vapier@gentoo.org>
builtins/setattr.def
- set_var_attribute: check whether bind_variable (called when the
variable whose attributes are being modified is found in the temp
environment) just modified a read-only global variable, and don't
bother marking the temporary variable for propagation if so. The
propagation is superfluous and will result in a strange error
message

variables.c
- initialize_shell_variables: don't try to import function definitions
with invalid names from the environment if already in posix mode,

through the environment. Print an error message so user knows
what's wrong. Fixes bug reported by Tomas Trnka <ttrnka@mail.muni.cz>

builtins/read.def
- sigalrm_seen, alrmbuf: now global so the rest of the shell (trap.c)

longjmp without manipulating signal mask, leaving SIGALRM blocked
quit.h
- move CHECK_ALRM macro here from builtins/read.def so trap.c:
check_signals() can call it
trap.c
- check_signals: add call to CHECK_ALRM before QUIT

CHECK_ALRM and QUIT inline. Integrating check for read builtin's

sig.c
- initialize_shell_signals: install a signal handler for SIGTERM
that does nothing except set a sigterm_received flag instead of
ignoring it with SIG_IGN, as long as SIGTERM is not ignored when
the shell is started. Use get_original_signal early to get the
original handler, since we will do that later anyway

handler, make sure to add SA_RESTART flag to make it as close to
SIG_IGN as possible
sig.h
- sigterm_sighandler: new extern declaration
quit.h
- RESET_SIGTERM: set sigterm_receved to 0
- CHECK_SIGTERM: check sigterm_received; if it's non-zero, treat it
as a fatal signal and call termsig_handler to exit the shell
jobs.c
- make_child: call RESET_SIGTERM just before fork() so we can detect
if the child process received a SIGTERM before it's able to change
the signal handler back to what it was when the shell started
(presumably SIG_DFL). Only has effect if the shell installed
sigterm_sighandler for SIGTERM, interactive shells that were not
started with SIG_IGN as the SIGTERM handler
- make_child: call RESET_SIGTERM in the parent after fork() so the
rest of the shell won't react to it
execute_cmd.c
- execute_simple_command: call CHECK_SIGTERM after make_child in child
to catch SIGTERM received after fork() and before restoring old
signal handlers
- execute_disk_command: call CHECK_SIGTERM after make_child in child
process after restoring old signal handlers and again just before
calling shell_execve. Fixes race condition observed by
Padraig Brady <p@draigbrady.com> when testing with his `timeout'

opens up a specified number of spaces to be overwritten
- insert_some_spaces: now just calls to open_some_spaces followed by
_rl_output_some_chars
- update_line: use col_temp instead of recalculating it using
_rl_col_width in the case where we use more columns with fewer bytes
- update_line: use open_some_spaces and then output the right number
of chars instead of trying to print new characters then overwrite
existing characters in two separate calls. This includes removing
some dodgy code and making things simpler. Fix from Egmont

- make_local_variable: if we find a variable with the tempenv flag
set at the same `level' as variable_context', but not found in the
temporary_env (temp environment preceding the builtin), return it.
The temp environment preceding the function call has already been
merged (in execute_function) into the list of variable contexts the

expand_string_internal, expand_string_if_necessary to create a
WORD_DESC and call call_expand_word_internal() on it directly.
We don't want process substitution to be performed ( 1<(2) ) should
mean something different in an arithmetic expression context.
It doesn't work to just turn on the DQUOTE flag, since that means
that things like ${x["expression"]} are not expanded correctly.

lib/readline/isearch.c
- _rl_isearch_dispatch: if we read an ESC and it's supposed to
terminate the search, make sure we check for typeahead with
_rl_pushed_input_available, since installing a hook function causes
typeahead to be collected in `ibuffer' (input.c). If there is any,
make sure we still use the ESC as a prefix character. Bug and fix

parse.y
- struct STRING_SAVER: now has a new `flags' element, to identify the
caller: alias expansion, double-paren parsing, or parse_and_execute
- push_string: now sets flags to PSH_ALIAS if `ap' argument is non-NULL
- push_string: now doesn't attempt to call strlen on a NULL string to
set shell_input_line_size
- parser_expanding_alias, parser_save_alias, parser_restore_alias: new
functions to provide an external interface to push_string and
pop_string; parser_save_alias sets flags element to PSH_SOURCE (could
be renamed PSH_EXTERN someday)
- shell_getc: when yy_getc returns '\0', instead of just testing
whether the pushed_string_list is not-empty before popping it, don't
pop if if the saved string has flags PSH_SOURCE, indicating that
parse_and_execute set it before setting bash_input to the string.
We should continue reading to the end of that string before popping
back to a potential alias. Partial solution for the problem of aliases
with embedded newlines containing `.' commands being executed out of
order reported by Andrew Martin <andrew.martin@gmail.com>
- shell_getc: when yy_getc returns '\0' and there is a saved string of
type PSH_SOURCE, restart the read without popping the string stack
if we have not read to the end of bash_input.location.string. Rest
of fix for out-of-order execution problem
externs.h
- parser_expanding_alias, parser_save_alias, parser_restore_alias: new
extern function declarations
builtins/evalstring.c
- pe_prologue: if the parser is expanding an alias, make sure to add
an unwind-protect to restore the alias; undoes the work that will be
performed by parse_and_execute/parse_string
- parse_and_execute,parse_string: after calling push_stream to save
bash_input, check whether or not the parser is currently expanding
an alias (parser_expanding_alias() != 0). If it is, we want to save
that string in the pushed_string_list, which we do with
parser_save_alias.

invisible characters. Fixes problem reported by Jinesh Choksi

rl_maybe_replace_line to do the work. Fixes problem reported by

sig.c
- sigint_sighandler: if we get a SIGINT (and this signal handler is
installed) while the wait builtin is running, note that we received
it in the same way as jobs.c:wait_sigint_handler and return. The
various wait_for functions will look for that with CHECK_WAIT_INTR.
This fixes the wait builtin not being interruptible in an interactive
job control shell
12/31
-----
trap.c
- set_signal_hard_ignored: rename set_signal_ignored to this, since it
both sets original_signals[sig] and sets the HARD_IGNORE flag
- set_signal_ignored: new function, now just sets original_signals[sig]
trap.h
- set_signal_hard_ignored: new external declaration
sig.c
- initialize_terminating_signals: call set_signal_hard_ignored instead
of set_signal_ignored for signals with disposition SIG_IGN when the
shell starts
execute_cmd.c
- setup_async_signals: make sure we get the original dispositions for
SIGINT and SIGQUIT before starting the subshell, and don't call
set_signal_ignored because that sets original_signals[sig]. If we
don't, subsequent attempts to reset handling using trap will fail
because it thinks the original dispositions were SIG_IGN. Posix

identifier
variables.h

variable, make sure the value is a valid variable name (checks done
by make_variable_value via bind_variable_value) and display an
error message, deleting the variable we just created, if it is not.

trap.c
- _run_trap_internal: use {save,restore}_parser_state instead of
{save,restore}_token_state, like in run_pending_traps(); don't
need to save and restore last_command_exit_value as a result
- _run_trap_internal: call {save,restore}_pipeline like in
run_pending_traps()
- run_pending_traps: since we no longer run traps in a signal handler
context, do not block and unblock the trapped signal while the
trap is executing
- run_pending_traps: allow recursive invocations (basically, running
traps from a trap handler) with only a warning if the shell is
compiled in debug mode. If a caller doesn't want this to happen,
it should test running_trap > 0. signal_in_progress (sig) only works
for the signals the shell handles specially
bashline.c
- bash_event_hook: make sure we clean up readline if interrupt_state
is set, not only when SIGINT is not trapped. check_signals_and_traps
will call check_signals, which calls QUIT, which will longjmp back
to top_level, running the interrupt trap along the way. Fixes the
problem of signal handlers being reset out from under readline, and
not being set properly the next time readline is called, because
signals_set_flag is still set to 1. XXX - might need to do this
for other signals too?

execute_cmd.c
- execute_simple_command: only posix-mode shells should exit on an
assignment failure in the temporary environment preceding a special
builtin. This is what the documentation and code comments have
always said
- execute_simple_command: make sure redirection errors, word expansion
errors, and assignment errors to Posix special builtins cause a
non-interactive posix mode shell to exit. Previously the shell
would not exit if the failed special builtin was on the LHS of ||
or &&
pathexp.c
- quote_string_for_globbing: when quoting a regular expression
(QGLOB_REGEXP), allow an unquoted backslash to pass through
unaltered. Don't use it as a quote character or quote it. More
investigation from 1/24 and report by Mike Frysinger
<vapier@gentoo.org>
- quote_string_for_globbing: when quoting a regular expression

backslash to quote it. We should not have to quote it because it is
not a character special to EREs. More investigation from 1/24
