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.

reference indexed array elements to the paragraphs describing
${parameter[subscript]}, since that's where they are implemented.

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
the next time the application calls into the readline callback
interface. Fixes problem of calling unsafe functions from signal
handlers when in callback mode reported by Jan Kratochvil

execute_cmd.c
- fix_assignment_words: when in Posix mode, the `command' builtin
doesn't change whether or not the command name it protects is an
assignment builtin. One or more instances of `command'
preceding `export', for instance, doesn't make `export' treat its
assignment statement arguments differently. Posix interpretation

doc/{bash.1,bashref.texi}
- document new Posix-mode behavior of `command' when preceding builtins
that take assignment statements as arguments
builtins/printf.def
- printstr: if fieldwidth or precision are < 0 or > INT_MAX when
supplied explicitly (since we take care of the `-' separately),
clamp at INT_MAX like when using getint(). Fixes issue reported
by Ralph Coredroy <ralph@inputplus.co.uk>
