				 ---------
[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

lib/readline/histexpand.c
	- history_expand: when processing a string within double quotes
	  (DQUOTE == 1), make the closing double quote inhibit history
	  expansion, as if the word were outside double quotes.  In effect,
	  we assume that the double quote is followed by a character in

doc/{bash.1,bashref.texi}
	- document that regexp matches can be inconsistent when quoting

	  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

lib/readline/bind.c
	- _rl_escchar: return the character that would be backslash-escaped
	  to denote the control character passed as an argument ('\n' -> 'n')
	- _rl_isescape: return 1 if character passed is one that has a
	  backslash escape
	- _rl_untranslate_macro_value: new second argument: use_escapes, if
	  non-zero translate to backslash escapes where possible instead of
	  using straight \C-x for control character `x'.  Change callers

lib/readline/rlprivate.h
	- _rl_untranslate_macro_value: extern declaration

lib/readline/{macro.c,readline.h}
	- rl_print_last_kbd_macro: new bindable function, inspired by patch

	  rl_print_last_kbd_macro

lib/readline/doc/{rluser.texi,readline.3},doc/bash.1
	- print-last-kbd-macro: document.

lib/readline/text.c

shell.c
	- init_noninteractive: instead of calling set_job_control(0) to
	  unconditionally turn off job control, turn on job control if
	  forced_interactive or jobs_m_flag is set
	- shell_initialize: call initialize_job_control with jobs_m_flag as
	  argument so `bash -m script' enables job control while running the
	  script

jobs.c
	- initialize_job_control: if the `force' argument is non-zero, turn on

	  includes a reference to the bash_completion project

				 1/1/2012
				 --------
jobs.c

quit.h
	- LASTSIG(): new macro, expands to signal number of last terminating
	  signal received (terminating_signal or SIGINT)

trap.c
	- first_pending_trap: returns lowest signal number with a trap pending
	- trapped_signal_received: set to the last trapped signal the shell
	  received in trap_handler(); reset to 0 in run_pending_traps

builtins/read.def
	- read_builtin: changes to posix-mode (posixly_correct != 0) to make
	  `read' interruptible by a trapped signal.  After the trap runs,
	  read returns 128+sig and does not assign the partially-read line
	  to the named variable(s).  From an austin-group discussion started

lib/readline/complete.c
	- _rl_colored_stats: new variable, controlled by colored-stats bindable
	  variable
	- colored_stat_start, colored_stat_end: new functions to set and reset

	  filename to be printed
	- print_filename: changes to print colors if `colored-stats' variable
	  set.  Changes contributed by Raphael Droz
	  <raphael.droz+floss@gmail.com>

lib/readline/readline.c
	- rl_initialize_everything: add call to _rl_parse_colors to parse
	  color values out of $LS_COLORS.  May have to add to rl_initialize
	  to make more dynamic if LS_COLORS changes (which doesn't happen
	  very often, if at all)

lib/readline/doc/{readline.3,rluser.texi},doc/bash.1
	- colored-stats: document new bindable readline variable

lib/readline/colors.c
	- _rl_print_color_indicator: call rl_filename_stat_hook before calling
	  lstat/stat so we can get color indicators for stuff like
	  $HOME/Applications

lib/readline/complete.c
	- stat_char: call rl_filename_stat_hook before calling lstat/stat

findcmd.[ch],execute_cmd.c
	- search_for_command: now takes a second `flags' argument; changed
	  header function prototype and callers
	- search_for_command: if (flags & 1), put the command found in $PATH
	  into the command hash table (previous default behavior)

execute_cmd.c
	- is_dirname: call search_for_command with flags argument of 0 so it
	  doesn't try to put something in the command hash table

bashline.c
	- bash_command_name_stat_hook: a hook function for readline's
	  filename_stat_hook that does $PATH searching the same way that
	  execute_cmd.c:execute_disk_command() does it, and rewrites the
	  passed filename if found.  Does not put names into command hash
	  table.  This allows command name completion to take advantage
	  of `visible-stats' and `colored-stats' settings.
	- executable_completion: new function, calls the directory completion
	  hook to expand the filename before calling executable_file or
	  executable_or_directory; change command_word_completion_function to
	  call executable_completion.  This allows $HOME/bin/[TAB] to do
	  command completion and display alternatives

pcomplete.c

	  name as deciphered by the programmable completion code and used
	  to look up the compspec; changed callers (gen_compspec_completions)
	- gen_shell_function_matches: now takes a new second argument: the
	  command that originally caused the completion function to be
	  invoked; changed callers (gen_compspec_completions))
	- build_arg_list: now takes a new second argument: the command name
	  corresponding to the current compspec; changed callers
	  (gen_command_matches, gen_shell_function_matches)
	- build_arg_list: now uses `cmd' argument to create $1 passed to
	  invoked command or shell function
	- gen_compspec_completions: if we skipped a null command at the
	  beginning of the line (e.g., for completing `>'), add a new word for
	  it at the beginning of the word list and increment nw and cw
	  appropriately.  This is all a partial fix for the shortcoming

builtins/gen-helpfiles.c

builtins/Makefile.in
	- tmpbuiltins.c: new generated file, created to enable creation of

	- CREATED_OBJECTS: new variable, holds created object files for
	  make clean; changed make clean to remove created objects

Makefile.in
	- when building libbuiltins.a, recursively call make with `targets'

	  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
	- wait_sigint_handler: don't longjmp out of the wait builtin unless
	  interrupt_immediately is set; otherwise just SIGRETURN from the
	  handler

trap.c
	- trap_handler: make sure wait_signal_received is set if the wait
	  builtin is executing, and only longjmp if interrupt_immediately is
	  set.  This whole set of fixes was prompted by report from
	  lanshun zhou <zls.sogou@gmail.com>

builtins/evalstring.c
	- parse_and_execute: treat ERREXIT case like reader_loop does: set
	  variable_context to 0 before longjmping back to top_level. Don't
	  run the unwind-protect context to avoid side effects from popping
	  function contexts.  Part of fix for problem reported by Nikolai
	  Kondrashov <nikolai.kondrashov@redhat.com>

execute_cmd.c
	- execute_simple_command: call unlink_fifo_list only if this is the
	  last element of a pipeline (or not in a pipeline), rather than for
	  every child.  Fixes difference in behavior between /dev/fd and
	  FIFOs reported by Zev Weiss <zev@bewilderbeest.net>

	  into a quoted null.  Fixes debian bug 692447 reported by
	  Matrosov Dmitriy <sgf.dma@gmail.com>

jobs.c
	- run_sigchld_trap: make sure `running_trap' sentinel is set
	  appropriately
	- waitchld: only run the sigchld trap if we're not in a signal
	  handler, not running a trap, and executing the wait builtin.
	  Otherwise, queue for later handling.  We still run one instance
	  of the trap handler per exited child.  Bulk of fix for bug
	  reported by Elliott Forney <idfah@cs.colostate.edu>

trap.c
	- queue_sigchld_trap: set catch_flag so run_pending_traps notices,

trap.c
	- run_pending_traps: set SIG_INPROGRESS flag around calls to
	  run_sigchld_handler so other parts of the shell know that the
	  SIGCHLD trap handler is executing
	- run_pending_traps: if we get a situation where we are looking at
	  running a SIGCHLD trap but the trap string is IMPOSSIBLE_TRAP_HANDLER
	  and the SIG_INPROGRESS flag is set, just skip it.  This is possible
	  if run_pending_traps is called from a SIGCHLD trap handler run by

	  jobs or no children or other errors.  Calls wait_for with new
	  sentinel value ANY_PID
	- wait_for: changes to handle argument of ANY_PID: don't look up or

	  Return -1 if waitpid returns no children

jobs.h
	- ANY_PID: new define

builtins/wait.def

	  are in horizontal mode; set to false in horizontal mode if the left
	  margin of the displayed line is greater than the end of the prompt
	  string
	- rl_redisplay: when in horizontal scroll mode, don't adjust

	  try to delete characters

builtins/read.def
	- unbuffered_read: set to 2 if invoked as `read -N'

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

	  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

	- push_string: now doesn't attempt to call strlen on a NULL string to

	- 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.

	  back to a potential alias. Partial solution for the problem of aliases
	  with embedded newlines containing `.' commands being executed out of

	- _run_trap_internal: call {save,restore}_pipeline like in

	- 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

	- darwin: combine the stanzas into one that will not require them to
	  be updated on each Mac OS X release.  Report and fix from Max Horn
	  <max@quendi.de>

support/shobj-conf
	- darwin: changed the install_name embedded into the shared library
	  to contain only the major version number, not the minor one. The
	  idea is that the minor versions should all be API/ABI compatible,
	  and it is better to link automatically with the latest one.  Idea
	  from Max Horn <max@quendi.de>

lib/readline/readline.h
	- rl_clear_history, rl_free_keymap: add extern declarations.  Report
	  from Hiroo Hayashi <hiroo.hayashi@computer.org>

general.c
	- include trap.h for any_signals_trapped() prototype

lib/sh/unicode.c
	- include <stdio.h> for sprintf prototype

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
	  (QGLOB_REGEXP), turn CTLESC CTLESC into CTLESC without adding a
	  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

lib/glob/glob.c
	- glob_testdir: now takes a second flags argument (currently unused);
	  changed prototype and callers

				    2/1
				    ---
lib/glob/glob.c
	- glob_testdir: if flags argument includes GX_ALLDIRS (globstar), use
	  lstat so we skip symlinks when traversing the directory tree.
	  Originally reported by Chris Down <chris@chrisdown.name>

				    ---
lib/readline/undo.c
	- rl_do_undo: make sure CUR is non-zero before dereferencing it to
	  check cur->data against rl_undo_list.  Report and fix from
	  Andreas Schwab <schwab@linux-m68k.org>

doc/{bash.1,bashref.texi}
	- added slight clarifying language to the description of $*,
	  describing what happens when the expansion is not within double
	  quotes

				    2/4
				    ---
test.c
	- unary_test: add code to -v case so that it interprets `bare' array
	  references (foo[1]) and returns true if that index has a value

				    2/5
				    ---
trap.c
	- restore_default_signal: fix SIGCHLD special case for SIG_TRAPPED flag
	  off but SIG_INPROGRESS mode set and handler IMPOSSIBLE_TRAP_HANDLER;
	  continue with resetting handler in this case. maybe_set_sigchld_trap
	  will check these things before resetting sigchld trap from
	  run_sigchld_trap.  Fixes (apparently long-standing?) problem reported
	  by Alexandru Damian <alexandru.damian@intel.com>

lib/sh/strtrans.c
	- ansic_quote: fixed a bug when copying a printable character that
	  consumes more than one byte; byte counter was not being incremented.
	  Bug report from jidanni@jidanni.org

				    2/7
				    ---
input.c
	- getc_with_restart: if read(2) returns -1/EINTR and interrupt_state or
	  terminating_signal is set (which means QUIT; will longjmp out of this
	  function), make sure the local buffer variables are zeroed out to
	  avoid reading past the end of the buffer on the next call.  Bug report
	  from Dan Jacobson <jidanni@jidanni.org>

				    2/9
				    ---
bashline.c
	- command_word_completion_function: if a directory in $PATH contains
	  quote characters, we need to quote them before passing the candidate
	  path to rl_filename_completion_function, which performs dequoting on
	  the pathname it's passed.  Fixes bug reported by Ilyushkin Nikita
	  <ilyushkeane@gmail.com>

				   2/11
				   ----
parse.y
	- xparse_dolparen: save and restore shell_eof_token around call to
	  parse_string, intead of just leaving it set to ')'
	- shell_getc: when -v is set, only print the command line when
	  shell_eof_token is 0, so we don't print it multiple times when
	  recursively entering the parser to parse $(...) commands.  Fixes
	  bug reported by Greg Wooledge <wooledg@eeg.ccf.org>

[changed release status to 4.3-release]

lib/sh/strtrans.c
	- ansic_quote: handle case where mbrtowc reports that the multibyte
	  sequence is incomplete or invalid.  Fixes bug reported by
	  Eduardo A. Bustamante López <dualbus@gmail.com>

				   2/14
				   ----
variables.c
	- find_variable_nameref_context: fix a problem that caused the loop
	  to go one context too close to the global context.  In some cases,
	  simple variable assignment would set a variable in the global
	  context instead of a local context.  Bug report from
	  Geir Hauge <geir.hauge@gmail.com>
