				 ---------

[bash-5.1 released]

				   12/7
				   ----
Makefile.in
	- bashline.o: add dependency on ${DEFDIR}/builtext.h. Report from
	  Fazal Majid <fazal@majid.org>

				   12/11
				   -----
builtins/wait.def
	- wait_builtin: don't assign the variable given with -p if there are no
	  jobs to wait for. Report and fix from Ouz <oguzismailuysal@gmail.com>

arrayfunc.c
	- kvpair_assignment_p: return non-zero if argument L appears to be a
	  key-value pair associative array compound assignment
	- expand_and_quote_kvpair_word: run a single word in a key-value pair
	  associative array compound assignment through the appropriate
	  expansions and single-quote the result

arrayfunc.h
	- kvpair_assignment_p, expand_and_quote_kvpair_word: extern declarations

subst.c
	- expand_oneword: detect whether VALUE appears to be a key-value
	  pair compound assignment and call the appropriate function to expand
	  each word in the resulting list. Fixes inconsistency reported by
	  oguzismailuysal@gmail.com

				   12/12
				   -----
subst.c
	- command_substitute: don't reset pipeline_pgrp to shell_pgrp if we
	  are already forked to run a command (SUBSHELL_FORK). Fixes SIGINT
	  in command substitution in here-document in forked child issue
	  reported by oguzismailuysal@gmail.com

				   12/18
				   -----
execute_cmd.c
	- execute_pipeline: execute the lastpipe code even if prev == 0. It
	  can only be 0 here if stdin was closed when this function was
	  executed
	- execute_pipeline: if prev == 0, set lstdin to a sentinel (-1) that
	  means to close fd 0 after executing the command, and call close(prev)
	  before restoring stdin. restore_stdin now understands -1, and closes
	  fd 0. Fixes issue reported by Tomas Janousek <tomi@nomi.cz>

				   12/21
				   -----
doc/bashref.texi
	- PROMPT_COMMANDS: clean up a couple of remaining instances of this
	  name. Report from Eli Schwartz <eschwartz@archlinux.org>

				   12/26
				   -----
subst.c
	- command_substitute: make sure that the child process always has
	  pipeline_pgrp == shell_pgrp: if pipeline_pgrp is non-zero when we
	  get to the child, meaning that we're part of an already-forked
	  child that is, for instance, running redirections, we need to reset
	  shell_pgrp to it to preserve the invariant. Fixes bug with terminal
	  being set to the incorrect pgrp reported by oguzismailuysal@gmail.com

				   12/29
				   -----
configure.ac,builtins/shobj-conf,m4/threadlib.m4
	- midnightbsd: update auto-configuration to treat MidnightBSD like
	  FreeBSD. From https://savannah.gnu.org/patch/?10006

				   12/30
				   -----
examples/loadables/stat.c
	- stattime: use strftime with a default format or the format supplied
	  with the -F option to format the file time information
	- stat_builtin: now takes a -F fmt option for a strftime format string;
	  change to function calling sequences to pass the format down to
	  stattime

examples/loadables/Makefile.in
	- stat: now built and installed by default

				   12/31
				   -----
command.h
	- SUBSHELL_IGNTRAP: new flag value

jobs.c
	- make_child: set SUBSHELL_IGNTRAP in subshell_environment in the
	  child process, meaning that we should not execute trap handlers for
	  trapped signals

execute_cmd.c
	- execute_in_subshell, execute_simple_command, execute_disk_command:
	  make sure to unset SUBSHELL_IGNTRAP after a child process restores
	  the original signal dispositions
	- execute_simple_command: make sure to set SUBSHELL_IGNTRAP after
	  make_child returns and we're setting subshell_environment directly

subst.c
	- command_substitute,process_substitute: unset SUBSHELL_IGNTRAP after
	  the child process has reset the trapped signal dispositions

trap.c
	- trap_handler: if we get a signal for which we have set a trap, but
	  SUBSHELL_IGNTRAP is set in subshell_environmnent, make sure we
	  restore the original signal disposition and resend the signal to
	  ourselves. Fixes issue reported by Nikolay Borisov <nborisov@suse.com>
	  (or at least makes the race window much smaller)

sig.c
	- initialize_terminating_signal: set the original signal handler from
	  the return value from sigaction; a minor optimization that saves a
	  system call or two

				 1/5/2021
				 --------
builtins/declare.def
	- declare_internal: make some option combinations that don't make
	  sense errors (e.g., -f and -a/-A/-i/-n)
	- declare_internal: if we build a new variable name by expanding the
	  value of a nameref variable, make sure to chop the `+' in a `+='
	  off before going on

				    1/7
				    ---
doc/{bash.1,bashref.texi}
	- bind: add an example to the synopsis making it clear that you can
	  use any readline command line as a non-option argument, as it says
	  in the text. From a report from Dan Jacobson <jidanni@jidanni.org>

				   1/12
				   ----
locale.c
	- local_shiftstates -> locale_shiftsates in the non-multibyte code
	  branch. Reported by Henry Bent <henry.r.bent@gmail.com>

subst.c
	- expand_compound_assignment_word: make sure to call dispose_words on
	  the WORD_LIST * returned from expand_oneword after turning it back
	  into a string. Fixes memory leak reported by Alexander Mescheryakov
	  <alexander.s.m@gmail.com>

				   1/13
				   ----
variables.c
	- bind_variable_internal: when performing an assignment to a subscripted
	  array variable that was the value of a nameref (used in the original
	  assignment), don't call make_variable_value on the value, since that
	  messes up +=. Just call assign_array_element and let that take care
	  of calling make_variable_value appropriately. Fixes bug reported by
	  Oguz <oguzismailuysal@gmail.com>

				   1/14
				   ----
findcmd.c
	- search_for_command: if `checkhash' is set, don't add non-executable
	  files to the command hash table, since we will just remove them
	  later

lib/sh/winsize.c
	- get_new_window_size: set *rp and *cp even if READLINE is not defined

				   1/15
				   ----
lib/sh/winsize.c
	- get_new_window_size: call rl_set_window_size only if we can determine
	  we're using readline: an interactive shell without no-line-editing,
	  or if we've already initialized readline, presumably in a non-
	  interactive shell 

support/Makefile.in
	- man2html: add LDFLAGS_FOR_BUILD to the recipe. Report from
	  Jeffrey Walton <noloader@gmail.com>

				   1/17
				   ----
lib/readline/misc.c
	- rl_operate_and_get_next: fix old K&R function declaration. Report
	  from Tom Tromey <tom@tromey.com>

lib/readline/readline.c
	- _rl_internal_char_cleanup: move code that cleans up the active region
	  and deactivates the mark inside this function so callback mode
	  applications get the intended functionality. Report and fix from
	  sparrowhawk996@gmail.com

lib/readline/bind.c
	- rl_parse_and_bind: when using the arithmetic comparison operators on
	  the version, make sure to invert the tests so that we stop parsing
	  if the test fails. Report and fix from Tom Tromey <tom@tromey.com>

				   1/19
				   ----
Makefile.in
	- pipesize.h: add dependency on ${BUILTINS_LIBRARY} to avoid parallel
	  makes trying to create it twice. Report and fix from
	  Richard Purdie <richard.purdie@linuxfoundation.org>

				   1/21
				   ----
subst.c
	- param_expand: if a nameref expands to array[@] or array[*], make sure
	  to call chk_atstar so the right variables are set to split the
	  result. Report from Oguz <oguzismailuysal@gmail.com>

				   1/22
				   ----
builtins/declare.def
	- Rewrote to reduce complexity. Still needs some work.

lib/readline/*.h, lib/tilde/tilde.h
	- PARAMS: remove, rely on compilers understanding function prototypes

lib/readline/{undo.c,histlib.h}
	 - _hs_replace_history_data: move extern declaration to histlib.h

lib/readline/readline.c
	- _rl_parse_colors: instead of an extern declaration for this, include
	  "parse-colors.h" for it

lib/readline/{histfile.c,histlib.h}
	- _hs_append_history_line: move extern declaration to histlib.h

lib/readline/history.h
	- HS_HISTORY_VERSION: define to 0x0801 (current library version) if
	  it's not already defined. We conditionally define it in case an
	  application has (unwisely) chosen to use it, since the history
	  library doesn't do anything with it yet

lib/readine/{rlprivate.h,{search,misc,readline}.c}
	- _rl_free_history_entry: add extern declaration to rlprivate.h, remove
	  extern declaration from c source files. Use HS_HISTORY_VERSION as a
	  sentinel that it's ok to use HIST_ENTRY in rlprivate.h

lib/readline/{rlprivate.h,{isearch,search,undo}.c}
	- _rl_saved_line_for_history: add extern declaration to rlprivate.h,
	  remove extern declaration from c source files, using HS_HISTORY_VERSION
	  in the same way

				   1/24
				   ----
lib/readline/signals.c
	- _rl_handle_signal: make sure that all sigprocmask calls are protected
	  by HAVE_POSIX_SIGNALS. Report and fix from Tom Tromey <tom@tromey.com>

				   1/26
				   ----
lib/readline/callback.c
	- rl_callback_read_char: make sure rl_linefunc is non-NULL before
	  calling through the pointer. The line function could have been
	  removed by the application before readline processes any typeahead
	  input. Bug reported by Matthias Klose <doko@debian.org>, pointer
	  to root cause from Koichi Murase <myoga.murase@gmail.com>

lib/glob/glob.c
	- skipname,wskipname: put in some additional checks for `.' to ensure
	  that we don't get false positives (or incomplete tests) that can 
	  affect the results of extglob patterns. Reported by
	  gregrwm <rhn-users@greatlakedata.com>

				   1/27
				   ----
lib/glob/glob.c
	- extglob_skipname,wextglob_skipname: fixed an off-by-one error (SE
	  was being set to one character before the end of the pattern string,
	  not the null character at the end of the pattern string like other
	  callers of glob_patscan) that caused the last character of the last
	  subpattern to be cut off when calling skipname
	- extglob_skipname,wextglob_skipname: some cleanups so the code is
	  closer to identical for the single-byte and wide character versions

				    2/1
				    ---
execute_cmd.c
	- execute_simple_command: in posix mode, if we have a variable
	  assignment error while assigning into the temporary environment (e.g.,
	  assigning to a readonly variable), a non-interactive shell running a
	  special builtin exits; a non-interactive shell running anything else
	  jumps back to the top level. A shell compiled with -DSTRICT_POSIX
	  exits unconditionally.
	- execute_simple_command: make sure posix mode sets $? to non-zero
	  if a variable assignment error occurs preceding a non-special builtin

subst.c
	- do_assignment_statements: take the code from expand_word_list_internal
	  that performs assignment statements, either standalone or preceding 
	  simple command names, and factor it out into this function
	- expand_word_list_internal: call do_assignment_statements where
	  appropriate

				    2/2
				    ---
lib/glob/glob.c
	- dequote_pathname: fix function definition for non-multibyte systems.
	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>

Makefile.in,doc/Makefile.in
	- for certain targets, remove files before creating them to deal with
	  symlinked build trees.
	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>

examples/loadables/accept.c
	- include limits.h before typemax.h
	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>

builtins/gen-helpfiles.c
	- if USING_BASH_MALLOC is defined, make sure to undefine malloc as well
	  as free. Fixes bug reported by George R Goffe <grgoffe@yahoo.com>

builtins/Makefile.in
	- install-help: now depends on $(HELPFILES_TARGET) so we make sure the
	  separate helpfiles are created before we try to install them if we
	  don't go through the `all' makefile target

configure.ac
	- HELPDIR: now ${datadir}/bash/helpfiles

				    2/3
				    ---
parse.y
	- parse_string_to_word_list: before expanding a compound assignment
	  statement body, make sure to save any alias that's currently being
	  expanded. Restore the alias after the compound assignment is parsed.
	  Reported back in 11/2020 by Alex fxmbsw7 Ratchev <fxmbsw7@gmail.com>

				    2/4
				    ---
lib/readline/histexpand.c
	- history_expand_internal: when calling the history_inhibit_expansion
	  function, make sure to call it using the string as we've expanded it
	  to that point (RESULT), adding the expansion and next characters
	  temporarily, since we make expansion decisions based on what we've
	  accumulated, not what we started with. This makes things like
	  echo abc!$!$ work, where before the second `!' inhibited expansion
	  because bash_history_inhibit_expansion mistakenly took it as the
	  second character in a `$!' word expansion. Fixes bug reported back
	  in 10/2020 by Paul Fox <paul.d.fox@gmail.com>

array.h
	- array_pop: instead of calling array_dispose_element from this macro,
	  just call array_shift with the AS_DISPOSE flag

				    2/5
				    ---
bashhist.c
	- shell_comment: move condition to return 0 if the delimiter stack is
	  not empty or the shell is parsing a here document into the function
	  itself, don't have the callers check so the check is in one place.
	  Fixes bug reported by Oguz <oguzismailuysal@gmail.com>

array.h,variables.c
	- ARRAY_ELEMENT_REPLACE: convenience define for modifying an array
	  element's value

variables.c
	- pop_args: a couple of code simplifications

				    2/7
				    ---
lib/malloc/malloc.c
	- pagesz: at least MALLOC_PAGESIZE_MIN (4096) bytes
	- union mhead: now 16-byte aligned on all systems, 32-bit and 64-bit
	  pointers
	- binsizes: since the smallest allocation overhead is now 16 bytes,
	  redo the buckets so binsizes[0] == 32; adjust the thresholds for
	  split/coalesce/prepopulate/mmap (NBUCKETS = 28; STARTBUCK = 0).
	  Sizes stay pretty much the same; indices change
	- consistently use MALLOC_SIZE_T instead of long/unsigned int/int
	- use MAGIC8_NUMBYTES as the length of the mh_magic8 buffer, in case
	  it changes later for alignment
	- internal_remap: new function, calls mremap to reallocate a chunk of
	  memory allocated using mmap(); called from internal_realloc if the
	  old size and new size are both bigger than the mmap threshold
	- internal_realloc: call internal_remap if the old size and new size
	  are both above the threshold where we use mmap for allocation

				   2/10
				   ----
include/timer.h
	- new file, declaration for a timer struct to be used by a set of
	  functions to implement timers using SIGALRM or select/pselect

lib/sh/timers.c
	- new file, set of functions to manipulate timer objects and timeouts
	  using SIGALRM or select/pselect. Inspired by a patch from
	  Koichi Murase <myoga.murase@gmail.com>. Not used yet

				   2/11
				   ----
builtins/read.def
	- read_builtin: if there is a timeout set, block SIGCHLD around calls
	  to zread and its siblings, or calls to readline for `read -e', so
	  SIGCHLD (and the consequent waitpid) doesn't interrupt the read.
	  Fixes bug reported by Koichi Murase <myoga.murase@gmail.com>, but
	  there may be a different fix coming

Makefile.in,builtins/Makefile.in
	- fix up dependencies, especially on builtins.h and builtext.h


				   2/12
				   ----
lib/readline/input.c
	- rl_read_key: if we set rl_done == 1, set RL_STATE_DONE as well
	  Reported by Koichi Murase <myoga.murase@gmail.com>

lib/readline/isearch.c
	- _rl_search_getchar: only call _rl_read_mbstring if rl_read_key returns
	  >= 0, avoid some work

lib/readline/vi_mode.c
	- _rl_vi_callback_change_char,_rl_vi_change_char: don't overwrite the
	  last replacement string if _rl_vi_callback_getchar returns -1.
	  It will likely make no difference, since the next read will return
	  an error or EOF, but being careful
	- rl_vi_overstrike: if _rl_overwrite_char doesn't return 0, break out
	  of the loop

lib/readline/text.c
	- _rl_overwrite_char: return 1 if _rl_read_mbstring returns < 0 so
	  we don't try to insert garbage

bashline.c
	- posix_edit_macros: handle rl_read_key() returning <= 0

				   2/15
				   ----
parse.y
	- read_comsub: make sure to turn on the LEX_RESWDOK flag if we are in
	  a case statement and read a `)', since we can get a valid `esac'.
	  Fixes bug reported by Oguz <oguzismailuysal@gmail.com>
	- read_comsub: if we're in a case statement, recognize `}' as a
	  reserved word and set the LEX_RESWDOK flag for the next word, since
	  we can get an esac (or another reserved word) after it

				   2/16
				   ----
parse.y
	- reserved_word_acceptable: add ARITH_CMD and COND_END to the list of
	  tokens that can precede a reserved word, so you can use reserved
	  words after ((...)) and [[...]].
	  Reported by Koichi Murase <myoga.murase@gmail.com>

				   2/17
				   ----
parse.y
	- parse_comsub: use new LEX_CASEWD flag to track when we are reading
	  the WORD in `case WORD in' and turn on the LEX_RESWDOK flag when
	  that word ends. This allows $(case x in esac), which no one uses.
	- parse_comsub: use LEX_PATLIST flag to track when we are reading a
	  case pattern list so `|' doesn't turn on the LES_RESWDOK flag
	- parse_comsub: case_level: simple counter to count the number of esacs
	  we need to see before we're no longer in a case statement; analog of
	  esacs_needed_count from the lexer

				   2/19
				   ----
parse.y
	- CHECK_FOR_RESERVED_WORD: don't return ESAC if we read `esac' after a
	  left paren in a case pattern list. From an austingroup-bugs discussion
	  about https://www.austingroupbugs.net/view.php?id=1454
	- parse_comsub: if we read a `(' while looking for a case pattern list
	  and LEX_CKESAC is set, we have a leading left paren in the pattern
	  list and should turn off LEX_CKESAC so (esac) doesn't prematurely
	  terminate the case command. From an austingroup-bugs discussion
	  about https://www.austingroupbugs.net/view.php?id=1454

				   2/26
				   ----
builtins/history.def
	- history_builtin: when checking negative offsets to -d, which are
	  supposed to count back from the end of the history list, check the
	  range against 0 instead of history_base, because the calculation is
	  done against history_length, which is independent of history_base.
	  Report and fix from Christopher Gurnee <chris@gurneeconsulting.net>

				   2/28
				   ----
doc/bashref.texi
	- replaced a number of uses of @var with a mixture of @env and @dfn
	  to better match up with the texinfo standards

doc/{bash.1,bashref.texi}
	- clarify some aspects of the coproc description, especially the
	  use of NAME and when it's optional

				    3/1

subst.c
	- read_comsub: fix off-by-one error in mbrtowc that causes a read one
	  character past the end of buf. Report and fix from
	  Platon Pronko <platon7pronko@gmail.com> in
	  https://savannah.gnu.org/patch/?10035

				    3/3
				    ---
builtins/ulimit.def
	- ulimit_builtin: Posix compatibility: if the last command specified
	  by an option does not have an option argument, but there is an
	  operand remaining after all the options are parsed, treat the
	  operand as an argument to that last command. From an austin-group
	  discussion and a Geoff Clare suggestion back in November, 2020.
	  Austin Group interpretation 1418

include/timer.h
	- SHTIMER_ALRMSET: new flag, indicates that there is an active alarm
	  associated with this timer (falarm() was called)

lib/sh/timers.c
	- shtimer_set: set the SHTIMER_ALRMSET flag after calling falarm

builtins/read.def
	- sigalrm,reset_timeout,check_read_timeout,read_builtin_timeout: new
	  and modified functions to use sh_timers for timeouts instead of
	  SIGALRM. Based on work contributed by Koichi Murase
	  <myoga.murase@gmail.com>
	- read_builtin: use sh_timers for read timeouts (-t N) instead of
	  using SIGALRM
	- edit_line: simulate receiving SIGALRM if readline times out (not
	  used yet)

				   3/11
				   ----
lib/readline/readline.c
	- rl_initialize: call _rl_timeout_init to set things up for any timeout	
	  that was set with rl_set_timeout
	- readline_internal_charloop: if we longjmped because of a timeout,
	  make sure to set rl_done/RL_STATE_DONE and return; we are
	  abandoning this call to readline(). The readline timeout changes
	  were based on work contributed by Koichi Murase
	  <myoga.murase@gmail.com>

lib/readline/readline.h
	- extern declarations for new timeout functions and hook
	- rl_clear_timeout: new define

lib/readline/callback.c
	- rl_callback_read_char: if we longjmped because of a timeout,

lib/readline/input.c
	- extern declarations for public and readline-library-private functions
	  and hooks to implement timeouts
	- rl_set_timeout,rl_timeout_remaining: new public functions

parse.y
	- parse_comsub: rewrite to recursively call the parser (yyparse()) and
	  return a string constructed from the resulting parse tree. Probably
	  will only work with bison. Error reporting is more accurate about
	  line numbers and invalid tokens, and command substitution errors 
	  are caught earlier, before expansion
	- DOLPAREN: new token, never created by yylex; only ever set by
	  parse_comsub and xparse_dolparen to indicate we're recursively
	  calling the parser for a command substitution
	- comsub: new grammar production that's triggered by DOLPAREN and
	  parses a command substitution, returning a <command>. It's one of
	  the possible end states for the top-level parser
	- grammar: only call rewind_input_string if the shell's input is
	  coming from a string
	- shell_ungets: push a string back onto the shell input; only used by
	  make_here_document for backwards compatibility -- allowing a here-
	  document to be terminated by a token at the end of a command
	  substitution
	- yylex: don't need any more special handling when returning
	  shell_eof_token, but we keep the clause for future work
	- read_token_word: don't handle backslashes (leave them in the input
	  stream) if we are reading a command substitution (PST_NOEXPAND)
	- reserved_word_acceptable: allow reserved words after DOLPAREN
	- report_syntax_error: better error handling if we hit EOF while
	  looking for the ending right paren in a command substitution
	- parse_string_to_word_list,parse_compound_assignment: make sure to
	  turn off parse_comsub sentinel temporarily

make_cmd.c
	- make_here_document: backwards compatibility: if we end a here
	  document on the same line as the end of a command substitution,
	  allow the token to terminate the here document (without requiring
	  a newline) and push the remainder of the line back for the parser
	  to consume and terminate the command substitution

builtins/evalstring.c
	- parse_string: if we read shell_eof_token and use it to terminate a

	  the parser uses to quote CTLESC and CTLNUL in *unquoted* words.

trap.c
	- restore_traps: inverse of reset_signal_handlers. This understands

	  leaving the trap string in place, and knows how to restore flags
	  and state based on that preserved trap string and whether or not
	  the signal is "special" to the shell.

builtins/exec.def
	- exec_builtin: instead of using restore_original_signals to completely
	  cancel the traps, call reset_signal_handlers so the trap strings are
	  preserved. Then if the exec fails (and we're not exiting) we can
	  look at the trap strings and see how to restore the trap state.
	  This calls restore_traps after reinitializing the shell signal
	  handlers, using the trap strings saved by reset_signal_handlers.
	  Fixes issue with not exiting after a failed exec clearing the EXIT
	  trap reported by Mark March <march@systempad.org>, using the
	  approach suggested by Robert Elz <kre@munnari.OZ.AU>

subst.c
	- expand_declaration_argument: when parsing options that modify
	  attributes that affect how the value is handled (i, c, u, etc.),
	  make sure to create an option string and call make_internal_declare

lib/readline/complete.c
	- rl_display_match_list: even if _rl_completion_prefix_display_length

	  through to fnprint via print_filename
	- fnprint: add the ellipsis if prefix_bytes exceeds the
	  _rl_completion_prefix_display_length, add explicit check for
	  prefix_bytes being longer since print_filename passes it through
	  if colored-completion-prefix is set. This means that while
	  completion-prefix-display-length still has precedence over
	  colored-completion-prefix, it doesn't override it if both are set
	  and the common prefix length is shorter than

	- unset_builtin: add shell compatibility level check <= bash-5.1 to
	  force `unset a[@]' to unset array variable `a', like in previous
	  versions, instead of unsetting associative array element `@' or
	  removing all elements of an indexed array without unsetting the
	  variable itself

builtins/common.c
	- set_expand_once: now a no-op if the shell compatibility level is
	  <= bash-5.1, preserving the previous versions' behavior for [[ -v
	  (dependent on assoc_expand_once instead of forcing it)

subst.c
	- parameter_brace_expand_rhs: make sure that the final value assigned
	  is always returned from ${a:=b}, even when `a' has a variable
	  attribute that modifies the value on assignment. Reported back on
	  1/20/2021 by oguzismailuysal@gmail.com; bash-5.2 tag removed

				   11/22
				   -----
doc/{bashref.texi,bash.1}
	- unset: change the description of `unset name[@]' (unset name[*])
	  to reflect the new behavior (unset associative array subscripts or
	  remove all elements from an indexed array) and the difference from
	  previous versions
	- set: document -r for restricted shell mode
	- restricted shell: change occurrences of `set +o restricted' to
	  `shopt -u restricted_shell'. From a report from
	  Jin Xiang <jxiang.sd@gmail.com>
	- read: note that read -t0 may return 0 if a subsequent read will
	  return EOF. From a suggestion by Dale R. Worley
	  <worley@alum.mit.edu>

execute_cmd.c
	- execute_arith_command,eval_arith_for_expr: don't pass EXP_EXPANDED
	  to evalexp if shell_compatibility_level > 5.1, assuming that the
	  expression has been quoted by Q_ARITH handling

test.c
	- test_arithcomp: if we're being called by the conditional command
	  code and treating the arguments to the arithmetic operators as
	  expressions, don't pass EXP_EXPANDED to evalexp if the shell
	  compatibility level is > 5.1, assuming that the expression has been
	  quoted by Q_ARITH handling

				   11/29
				   -----
examples/loadables/getconf.[ch]
	- getconf: new implementation of loadable builtin, based on glibc
	  getconf

examples/loadables/sleep.c
	- parse_gnutimefmt: parse GNU interval format (2m30s), returning
	  seconds and microseconds like uconvert
	- sleep: use parse_gnutimefmt if uconvert can't parse the format right
	  away and "dhms" appears in the format string. Don't return
	  EX_DISKFALLBACK under any circumstances

				   11/30
				   -----

builtins/wait.def
	- wait_builtin: refer to unset_waitlist only if JOB_CONTROL is enabled.
	  Report from Joel Ebel <jbebel@google.com>

parse.y,builtins/set.def
	- changes for minimal config restrictions

configure.ac,config.h.in
	- --enable-translatable-strings: new configuration option to allow
	  $"..." support to be compiled in or out; not included in the minimal
	  shell configuration

shell.c
	- main: don't include any of the dump-strings options if
	  TRANSLATABLE_STRINGS is not defined

lib/sh/shquote.c
	- sh_backslash_quote_for_double_quotes: needed for translatable strings

parse.y
	- support for translating $"..." strings now conditional on
	  TRANSLATABLE_STRINGS

locale.c
	- locale_expand: now conditional on TRANSLATABLE_STRINGS

subst.c
	- expand_string_dollar_quote: support for $"..." now conditional on
	  TRANSLATABLE_STRINGS

doc/bashref.texi
	- --enable-translatable-strings: document new configuration option

				   12/2
				   ----
subst.c
	- verify_substring_values: now that the default compatibility level is
	  52, and the Q_ARITH code is enabled, make the EXP_EXPANDED flag for
	  evalexp() dependent on the compatibility level
	- param_expand: arithmetic substitution: make EXP_EXPANDED flag
	  for evalexp() dependent on the compatibility level
	- expand_word_internal: don't call expand_array_subscript if the
	  shell compatibility level is 51 or below (Q_ARITH)

test.c
	- test_unop: if the shell compatibility level is > 51, using [@] with
	  an existing associative array will report on a key of `@'

arrayfunc.c
	- array_expand_index: if the compatibility level is > 51, Q_ARITH is
	  used and we don't pass EXP_EXPANDED to evalexp()

COMPAT,doc/bashref.texi
	- shell compatibility mode: document effects of setting the
	  compatibility mode to 51

				   12/3
				   ----
lib/malloc/malloc.c
	- mremap: only use if MREMAP_MAYMOVE is defined, since we use the Linux
	  version of the function signature

				   12/6
				   ----
bashhist.c
	- bash_add_history: if we're parsing a here-document (PST_HEREDOC), only
	  suppress adding the newline between lines if we're not at the first
	  line of the here-document (here_doc_first_line != 0). From a report
	  by S0AndS0 <strangerthanbland@gmail.com>

				   12/8
				   ----
lib/readline/colors.c
	- _rl_custom_readline_prefix: use STREQN to check for the extension
	  string in $LS_COLORS, since it's not necessarily null-terminated.
	  From https://savannah.gnu.org/patch/?10158

				   12/10
				   -----
variables.c
	- set_int_value,set_string_value: broke common code for setting int
	  and string dynamic variable values out into separate functions;
	  changed all callers to use them where appropriate. set_int_value
	  takes a flags argument saying whether or not to force the integer
	  attribute on
	- assign_random: store the value assigned as the variable value so
	  things like RANDOM=42; RANDOM+=7 generate consistent sequences
	  like in ksh93
	- assign_seconds: store the value assigned as the variable value so
	  things like SECONDS=42 ; SECONDS+=7 generate what's expected

doc/Makefile.in
	- changes to allow man pages that include others (.so FN) to be built
	  outside the source tree

				   12/13
				   -----
arrayfunc.c
	- assign_array_element_internal: take an additional argument: char **NVALP.
	  If non-null, it gets the value eventually assigned to the array
	  element
	- assign_array_element: take an additional NVALP argument; pass it to
	  assign_array_element_internal

arrayfunc.h
	- assign_array_element: new extern function declaration

{subst,variables}.c,builtins/{common.c,declare.def}
	- assign_array_element: change callers

subst.c
	- parameter_brace_expand_rhs: for the ${param:=value}, use the value
	  returned by assign_array_element in NVALP as the return value, since
	  it's the value ultimately assigned to the variable after possible
	  modification (e.g., arithmetic evaluation). Reported by
	  oguzismailuysal@gmail.com after flawed fix applied 11/16

				   12/14
				   -----
arrayfunc.h
	- array_eltstate_t: an object that encapsulates an array element's
	  state (type, index, key, value) whether it's an indexed or
	  associative array

arrayfunc.c
	- {init,flush}_eltstate: new functions to initialize and flush any
	  allocated memory from array_eltstate_t objects. No allocation/
	  deallocation functions yet; the only use is with a static instance
	- assign_array_element_internal: take an array_eltstate_t * instead of
	  a char ** as the final argument, so we can return keys/indices and
	  values depending on the type of array; populates it with the
	  appropriate values
	- assign_array_element: take array_eltstate_t * as final argument
	  instead of a char **; pass it to assign_array_element_internal

{subst,variables}.c,builtins/{common.c,declare.def}
	- assign_array_element: change callers to modify final argument

				   12/15
				   -----
arrayfunc.c
	- array_value_internal: now takes an array_eltstate_t * as the final
	  argument; there is no more `rtype' argument in favor of the
	  `subtype' member; returns the appropriate values in its members
	- array_value: changed to pass array_eltstate_t to array_value_internal,
	  saves and fetches its `ind' member into *indp; saves `subtype'
	  member into *rtype
	- get_arrary_value: changed to take array_eltstate_t as third argument,
	  passes it to array_value_internal

{redir,expr}.c
	- get_array_value: changed callers; initializing the array_eltstate_t
	  argument as necessary

test.c
	- test_builtin: changed to use get_array_value, adding AV_ALLOWALL to
	  the flags, since it didn't use any QUOTED argument. Pass
	  array_eltstate_t * as final argument and get subtype from it (the
	  only thing we're interested in, to deallocate memory)

				   12/16
				   -----
arrayfunc.c
	- array_value: now takes a final argument of array_eltstate_t *, which
	  it passes to array_value_internal; no more rtype and indp args.
	  Callers are responsible for marshalling values into estatep

arrayfunc.h
	- array_value: changed function signature

subst.c
	- get_var_and_type,parameter_brace_expand_word: changed calls to
	  array_value to use array_eltstate_t argument and initialize it
	  appropriately. Copy values back from it to the parameters we need
	  to modify

variables.c
	- assign_lineno: call set_int_value to store the value, like with
	  RANDOM and SECONDS (from 12/10)

				   12/17
				   -----
{eval,execute_cmd}.c
	- when bypassing a parsed command because read_but_dont_execute is
	  set, don't modify last_command_exit_value. From a report by
	  Robert Elz <kre@munnari.OZ.AU>

parse.y
	- parse_comsub: make sure the first call to shell_getc to check whether
	  or not it's an arithmetic expansion skips a quoted newline. From a
	  report by Robert Elz <kre@munnari.OZ.AU>

				   12/21
				   -----
subst.c
	- parameter_brace_remove_pattern,parameter_brace_patsub,parameter_brace_casemod,
	  parameter_brace_transform,parameter_brace_substring: now take an
	  array_eltstate_t * argument in place of the arrayind_t argument, pass
	  it to get_var_and_type; this generalizes the indexed array behavior
	  of expanding array subscripts once to associative arrays via an
	  eventual call to array_value_internal with a non-null KEY member
	- get_var_and_type: now takes an array_eltstate_t * argument in place
	  of the arrayind_t argument; use it in calls to array_value so we
	  can only expand array subscripts once whether they are indexed or
	  associative arrays
	- parameter_brace_expand_word: take an array_eltstate_t * argument in
	  place of the arrayind_t * argument; pass it to array_value; use a
	  static version (which we init and flush) if the argument passed is
	  NULL so we can get the right state passed back and forth
	- parameter_brace_expand: pass a pointer to a static array_eltstate_t
	  to parameter_brace_expand_word, and use that in the various calls to
	  parameter_brace_XXX functions that perform specific expansions in
	  place of the old arrayind_t argument; make sure to flush it before
	  returning, even on errors

				   12/22
				   -----
{trap,variables}.c
	- internal_warning: calls changed to use translatable strings
	  consistently

error.[ch]
	- internal_debug: new function, prints a message like internal_warning,
	  no-op if DEBUG is not defined
	- INTERNAL_DEBUG: macro that expands to internal_debug when DEBUG is
	  defined, and nothing otherwise

{jobs,trap}.c
	- changed some internal_warning and internal_inform calls to use
	  internal_debug, since they were active only when DEBUG is defined

parse.y
	- parse_comsub: add internal_debug call when a command substitution
	  ends with unterminated here-documents

builtins/common.c
	- number_of_args: unconditionally return posparam_count

{jobs,execute_cmd,subst}.c,parse.y,builtins/{command.def,evalstring.c}
	- INTERNAL_DEBUG: use instead of calls to itrace protected by #ifdef
	  DEBUG

				   12/26
				   -----
lib/glob/glob.c
	- glob_always_skip_dot_and_dotdot: initialize to 1 (enabled)

builtins/shopt.def
	- globskipdots: new shell option, exposes glob_always_skip_dot_and_dotdot

doc/{bash.1,bashref.texi}
	- globskipdots: document new shell option

execute_cmd.c
	- fix_arrayref_words: call valid_array_reference with 0 for third arg
	  because the words have not undergone any word expansions yet and
	  the quotes are still present. This makes things like
		A=[\[]=set
		unset A[\[]
	  work

subst.c
	- word_list_split: if a word undergoes word splitting but is not
	  changed, preserve any W_ARRAYREF flag into the new word. This makes
	  things like
		rkey=']'
		unset A[$rkey]
	  work because the unset builtin sees the W_ARRAYREF flag on its
	  argument

				   12/29
				   -----
builtins/common.h
	- SET_VFLAGS: take a set of word flags, and set flags for use with
	  valid_array_reference (vflags) and assign_array_element/bind_int_variable
	  (bindflags) based on those flags and the setting of assoc_expand_once
	  (moved from read.def and generalized)

arrayfunc.c
	- array_variable_name: now exclusively takes AV_xxx flags; understands
	  how to translate AV_NOEXPAND to the right flag for skipsubscript;
	  understands AV_ONEWORD and AV_NOEXPAND
	- array_variable_part: just passes the FLAGS arg to array_variable_name
	- assign_array_element: translates ASS_ flags to AV_ flags for
	  array_variable_name
	- array_value_internal: now just passes flags straight through to
	  array_variable_part (which sends them to array_variable_name)

builtins/common.[ch]
	- builtin_bind_var_to_int: now takes a new FLAGS third argument; passes
	  it to bind_var_to_int

builtins/printf.def
	- printf_builtin: use SET_VFLAGS to set flags for builtin_bind_variable
	  (bindflags); makes things like
		declare -A A; key=']' ; printf -v A[$key] "foo"
	  work without a subscript error as long as assoc_expand_once is defined

builtins/read.def
	- read_builtin: use new common version of SET_VFLAGS instead of
	  private version; changed to use new calling sequence; makes things like
		declare -A A; key=']' ; read A[$key] <<<"foo"
	  work without a subscript error as long as assoc_expand_once is defined

builtins/wait.def
	- wait_builtin: use SET_VFLAGS for variable name with -p option
	- wait_builtin: call builtin_bind_var_to_int with new bindflags third
	  argument

expr.c
	- expr_streval: just pass TFLAG (AV_xxx flags) straight through to
	  array_variable_part

variables.c
	- bind_int_variable: translate the assignment flags (ASS_xxx) to
	  VA_xxx flags for valid_array_reference calls (ASS_ONEWORD); translate
	  assignment flags to AV_xxx flags for array_variable_part

				   12/30
				   -----
subst.c
	- parameter_brace_expand: when expanding an indirect variable, extend
	  the special case for array[@] and array[*] (set -u/no positional
	  parameters, obeying the baroque quoting rules) to the value of the
	  indirection. Report and fix from konsolebox <konsolebox@gmail.com>

				   12/31
				   -----
parse.y
	- compound_list: when parsing a compound_list production, collect any
	  pending here-documents after reading a newline, not after reading
	  any command terminator. Fixes interactive-only prompting bug
	  reported back in 8/2021 by Hyunho Cho <mug896@gmail.com>

				 1/1/2022
				 --------
bashline.c
	- set_filename_quote_chars: break code that modifies
	  rl_filename_quote_characters based on whether DIRNAME needs to be
	  expanded from bash_directory_completion_hook into its own function
	- bash_check_expchar: break code that checks whether DIRNAME will be
	  word expanded from bash_directory_completion_hook into its own
	  function 
	- bashline_reset,attempt_shell_completion: make sure complete_fullquote
	  is set to 1 (as it is by default) in case a completion modifies it
	- bash_quote_filename: if we are completing (but not expanding --
	  direxpand is unset) and backslash-quoting a filename with expansion
	  characters as determined by bash_check_expchar, make sure
	  filename_bstab is set not to include the expansion char (and any
	  following char and closer) and set complete_fullquote to 0 so
	  sh_backslash_quote uses filename_bstab. Fixes the longstanding issue
	  of quoting a `$', for instance, if the rest of the filename contains
	  any characters that need quoting in filenames. This assumes that the
	  filename is unquoted (*QCP == 0) so the word will be expanded and is
	  not part of the filename (if needed, we can use file_exists to check
	  whether the expansion characters are actually part of the filename)

				    1/7
				    ---
examples/loadables/accept.c
	- new -b bindaddr option to bind to a specific IP address
	- move setsockopt calls before bind() to avoid TIME_WAIT issues. Fixes
	  from Dzogovic Vehbo <dzove855@gmail.com>

				   1/10
				   ----
configure.ac
	- bumped version to 5.2-alpha.

				   1/16
				   ----

tests/{unicode1,glob2,intl2}.sub, tests/run-intl
	- minor changes to add warnings for missing locales that cause test
	  failures

				   1/17
				   ----
parse.y
	- history_delimiting_chars: if we have a blank line by the time we
	  hit the end of the tests, return a semicolon for the first blank
	  line to avoid running lines of a multi-line command together.
	  Fixes bug reported by Joakim Lindblad <joakim@cb.uu.se>

subst.c
	- expand_string_for_patsub: expand the replacement string for pattern
	  substitution assuming that it will eventually be passed to
	  strcreplace to replace `&' with the matched portion of the string.
	  This calls expand_string_for_pat(), which leaves the string quoted
	  and does not perform word splitting, then calls
	  quote_string_for_repl to post-process the expanded string.
	- quote_string_for_repl: perform quote removal on passed string while
	  replacing CTLESC escaping a `&' or a backslash with a backslash. The
	  result must be passed to strcreplace
	- parameter_brace_patsub: call expand_string_for_patsub if
	  patsub_replacement is set to quote 

				   1/18
				   ----
subst.c
	- read_comsub: make istring_index a size_t to avoid overflow with very
	  large values of istring_size.
	  From https://savannah.gnu.org/support/index.php?110596
	- expand_word_internal: make istring_index a size_t

				   1/20
				   ----
buitins/cd.def
	- add a description of `cd -' to the help text. Suggested by
	  Rob Landley <rob@landley.net>

				   1/21
				   ----
lib/glob/glob.c
	- glob_vector: if we allocate NEXTLINK using malloc, and free it due to
	  some allocation failure, reset FIRSTMALLOC to avoid duplicate frees
	  later on

subst.[ch]
	- sub_append_string: the INDX parameter is now a size_t to avoid
	  overflow

parse.y
	- decode_prompt_string: RESULT_INDEX is now a size_t to pass to
	  sub_append_string

jobs.[ch],nojobs.c
	- wait_for_background_pids: now returns the number of jobs/processes
	  reaped

builtins/wait.def
	- wait_builtin: if -p pid supplied without -n, make sure we do something
	  useful if no job/pid arguments are supplied and there are no jobs.
	  Reported by Oguz <oguzismailuysal@gmail.com>

builtins/read.def
	- read_builtin: if we have a timeout, use SIGALRM instead of select
	  when in posix mode, since we use read instead of zread. Fixes bug
	  reported by Andreas Schwab <schwab@linux-m68k.org>

subst.c
	- expand_string_dollar_quote: handle single-quoted and double-quoted
	  strings that might include $' and $" without attempting translation;
	  do more error checking for unterminated $' and $" that leaves those
	  characters unmodified. This is for use by readline's various line
	  expansion functions (shell_expand_line)

				   1/23
				   ----
parse.y,make_cmd.c
	- revert change that unconditionally processes $'...' and $"..." in
	  here-document bodies; there are only a couple of cases where they
	  should be processed in a double-quote environment

				   1/24
				   ----

subst.c
	- extract_dollar_brace_string: if we see another `${' on the rhs of
	  the operator, reset the dolbrace_state to DOLBRACE_PARAM while we
	  read this new ${...} string
	- extract_heredoc_dolbrace_string: new function, variant of
	  extract_dollar_brace_string, to process the WORD in ${PARAM OP WORD}
	  while expanding lines of here-document data. It's complicated by the
	  requirement to add to the result string as we go along, since we
	  need to change the contents of the input string with ansi expansion
	  or locale translation.
	- string_extract_single_quoted: take a new third argument: ALLOWESC.
	  This allows backslash to escape an embedded single quote, needed by
	  extract_heredoc_dolbrace_string to process $'...'; changed callers

				   1/25
				   ----
parse.y
	- parse_matched_pair: ansi-expand $'...' in WORD for ${PARAM OP WORD}
	  and single-quote the result if dolbrace_state == DOLBRACE_QUOTE
	  (posix pattern removal operators) even if extended_quote == 0

subst.c
	- extract_heredoc_dolbrace_string: add logic to align with parse.y:
	  parse_matched_pair and its $'...' expansion, including handling
	  extended_quote

				   1/27
				   ----
builtins/evalstring.c
	- should_optimize_fork: broke conditions for optimizing away the fork
	  for a simple command out of optimize_fork into new function, call
	  from should_suppress_fork and optimize_subshell_command. Call from
	  optimize_fork if (subshell_environment & SUBSHELL_PAREN), relying
	  on fact that CMD_TRY_OPTIMIZING is only set in a couple of specific
	  conditions
	- optimize_fork: call should_suppress_fork only if startup_state == 2;
	  it does the extra checks for that specific case
	- optimize_fork: call should_optimize_fork if we're in a (list)
	  subshell (subshell_environment & SUBSHELL_PAREN)
	- optimize_subshell_command: set CMD_TRY_OPTIMIZING on the right side
	  of a `&&', `||', or `;' list as long as it's a simple command so
	  we can check with optimize_fork() when it's time to execute it

execute_cmd.c
	- execute_in_subshell: call optimize_subshell_command for (list)
	  subshells to either set CMD_NO_FORK for simple commands or set
	  CMD_TRY_OPTIMIZING for likely candidates for later optimization

builtins/common.h,builtins/evalstring.c
	- optimize_fork: renamed to optimize_connection_fork; changed callers

				   1/31
				   ----
include/shmbutil.h
	- COPY_CHAR_I,SCOPY_CHAR_I: add check for locale_utf8locale and
	  (c & 0x80) as in other macros

lib/sh/shquote.c
	- sh_backslash_quote_for_double_quotes: rewrote to use array indexing
	  and COPY_CHAR_I to make it easier to drop in future calls to
	  charvis() to make `unsafe' characters visible if FLAGS == 1

				    2/1
				    ---
parse.y
	- parse_comsub: if we are currently expanding aliases, temporarily
	  turn off alias expansion if we are not in posix mode so we defer
	  alias expansion until command_substitute(). Fixes double-expansion
	  bug reported by Martijn Dekker <martijn@inlv.org> and aligns with
	  https://www.austingroupbugs.net/view.php?id=1342
	- xparse_dolparen: turn off alias expansion entirely while running the
	  parser: either we do it in parse_comsub (posix mode) or in
	  command_substitute (default mode)
	- parse_string_to_command: ditto

subst.c
	- command_substitute: if we are expanding aliases, temporarily turn
	  off alias expansion if we are in posix mode, since we already
	  performed it in parse_comsub() and are using the command string
	  reconstituted from the parse result

doc/bashref.texi
	- bash posix mode: add description of alias expansion and command
	  substitution parsing and execution

lib/readline/rltty.c
	- rl_deprep_terminal: set _rl_last_c_pos to 0 after outputting
	  BRACK_PASTE_FINI, since the last character in that is \r. Partially
	  address issue raised by Markus Schwarzenberg <markus.schwarzenberg@freenet.de>

{arrayfunc,variables}.c
	- ARRAY_EXPORT: changes to encode array and assoc variables using a
	  scheme similar to shell functions so we can export arrays and
	  differentiate them from scalar variables and differentiate array
	  and assoc variables. Still not enabled by default.

variables.c
	- mk_env_string: third argument is now the variable's attributes or 0,
	  with all the attributes we can export arrays

lib/readline/bind.c
	- active-region-start-color,active-region-end-color: new bindable
	  string variables, one to set the active region color (instead of
	  standout mode) and one to turn it off (instead of the "se" terminal

builtins/reserved.def
	- !: add short help text

lib/readline/complete.c
	- make_quoted_replacement: if readline found quote characters anywhere
	  in the filename, but is not completing on an unclosed quoted string,
	  and there is an application filename quoting function, let that
	  function quote the filename if necessary

bashline.c
	- COMPLETE_DQUOTE2: new completion quoting style define
	- bash_expand_filename: new function, runs a filename passed to it
	  through word expansion, suppressing command and process substitution
	  and returns the result (in new memory if it's different than the
	  filename argument)
	- bash_quote_filename: if the return value from bash_check_expchar is
	  `$' or ``', expand the filename and if it contains characters that
	  should be quoted, set the quoting style to COMPLETE_DQUOTE2
	- bash_quote_filename: if the completion quoting style is COMPLETE_DQUOTE2,
	  use sh_mkdoublequoted to put double quotes around the entire
	  unexpanded filename instead of using sh_double_quote, which will
	  backslash-quote any `$'. This is a start at preserving user-supplied
	  quotes if the (expanded) completed filename requires them. From

	  L A Walsh <bash@tlinx.org> and Manuel Reiter <manuel.reiter@dwd.de>
	  back in 9/2018
	- MAX_CASE_NEST: doubled to 256, renamed to MAX_COMPOUND_NEST
	- read_token_word: add `if', `while', and `until' to the set of
	  compound commands that use WORD_TOP and WORD_LINENO (with
	  corresponding changes to grammar productions)
	- [grammar]: changed check to decrement WORD_TOP to >= 0 since we
	  start at -1 and we want to decrement back to -1 when all loops are
	  closed

builtins/jobs.def
	- jobs_builtin: call notify_and_cleanup after displaying the status of

lib/glob/sm_loop.c
	- PARSE_SUBBRACKET: a reworked PARSE_COLLSYM, generalized to handle

	- BRACKMATCH: change to use PARSE_SUBBRACKET consistently to parse
	  [:, [=, and [. special bracket expressions
	- PATSCAN: takes new FLAGS arg, changed all callers to just pass the
	  flags they get through to PATSCAN
	- PATSCAN: call PARSE_SUBBRACKET for [:, [=, and [. to treat them
	  consistently (uses FLAGS argument here)
	- PATSCAN: handle FNM_NOESCAPE appearing in FLAGS argument
	This set of fixes contributed by Koichi Murase <myoga.murase@gmail.com>

lib/glob/{glob,gmisc}.c
	- PATSCAN: change all callers to add extra flags arg of 0

doc/{bash.1,bashref.texi}
	- trap description: replace ARG with ACTION
	- clarify the language describing what trap without arguments and
	  trap -p without arguments display 
	- clarify that trap in non-interactive shells does not allow signals
	  that were ignored at shell start to be trapped; interactive shells
	  allow this
	- trap: add missing command types to the description of when the
	  DEBUG trap is executed

builtins/trap.def
	- LONG_DOC: replace ARG with ACTION

pcomplete.c

	  every time gen_progcomp_completions runs, set to 1 in
	  gen_compspec_completions if this_shell_builtin == compgen_builtin
	- gen_shell_function_completions: call rl_clear_signals and
	  rl_set_signals so the shell's signal handlers are active when
	  running shell functions to generate completions. We try to do it
	  only when programmable completion, not the compgen builtin, is active.
	  Idea from Koichi Murase <myoga.murase@gmail.com>, fixes bug
	  reported in 9/22

sig.c
	- sigint_sighandler, termsig_sighandler: since these can now be called
	  during programmable completion, we need to set the readline signal
	  event hook if the readline state includes RL_STATE_DISPATCHING or
	  RL_STATE_COMPLETING, since we can't rely on RL_STATE_SIGHANDLER
	  being set and we want to call throw_to_top_level here
	- throw_to_top_level: if the shell is interactive, before calling
	  bashline_reset (which zeroes rl_signal_event_hook), call
	  rl_cleanup_after_signal if we think readline hasn't called it
	  already

trap.c
	- trap_variable_context -> trap_return_context, initialize from

	  shell function execution and `./source', both of which can use
	  `return'. Idea from Koichi Murase <myoga.murase@gmail.com>

builtins/common.c
	- get_exitstat: compare trap_return_context against funcnest+sourcenest,
	  since that's how it's initialized now

lib/readline/readline.c
	- readline_internal_charloop: if we're not using the callback interface,
	  don't restore _rl_top_level from olevel, since we will just be going

	  the ANYOTHERKEY binding as a null string
	  From a report and patch by Grisha Levit <grishalevit@gmail.com>
	- rl_untranslate_keyseq: make changes analogous to
	  _rl_untranslate_macro_value so that we don't print control characters
	  directly
	- rl_invoking_keyseqs_in_map: if the key corresponds to a keymap, use
	  _rl_get_keyname to get its text representation, so this function
	  returns consistent results
	- rl_translate_keyseq: if convert-meta is on, don't convert meta chars
	  that are, e.g., \M-\C-@ (128) into \e followed by a NUL, resulting
	  in truncated key sequences. Just don't honor convert-meta in this

subst.c,subst.h
	- rename quote_rhs -> quote_nosplit

				   2/19
				   ----

subst.c
	- quote_var_value: break the code that quotes a variable value ($x,
	  ${x}, ${x[n]}, etc.) into a separate inline function and call it
	  from param_expand and parameter_brace_expand_word so they do it
	  consistently
	- param_expand: quote $* appropriately using quote_nosplit if we are
	  in a place where word splitting will not occur (PF_NOSPLIT2),
	  expand_no_split_dollar_star == 1 but quoted is 0
	- quote_var_value: use quote_nosplit if we are in a place where word
	  splitting will not occur (PF_NOSPLIT2) but quoted == 0.
	  Fixes bug with IFS=$'\1' reported by alex xmb sw ratchev <fxmbsw7@gmail.com>

arrayfunc.c
	- array_value: make sure to quote ${A[*]} appropriately if not quoted
	  (quoted == 0) and in a place where word splitting does not occur
	  (flags & AV_ASSIGNRHS); the caller expects array_value to quote in
	  this case

subst.c
	- parameter_brace_expand_word: make sure to call array_value with
	  AV_ASSIGNRHS if we are expanding unquoted ${A[*]} in a place where
	  word splitting does not occur with a non-null $IFS; array_value will
	  quote appropriately here
	- parameter_brace_expand_word,param_expand: use quote_var_value when
	  expanding $N and ${N}

doc/bash.1,doc/bashref.texi
	- HISTIGNORE: clarify the description a little to emphasize that lines
	  matching one of the patterns are not saved in the history list

	  errno == EINTR, retry the open after checking for interrupts or
	  terminating signals
	- maybe_execute_file,force_execute_file: pass FEVAL_RETRY in flags

bashhist.c
	- load_history: retry read_history if it returns EINTR after checking
	  for interrupts or terminating signals 

lib/readline/bind.c
	- _rl_read_init_file: retry the open once if it's interrupted due to a
	  signal. If we are at a point where readline has installed its
	  signal handlers, check for signals readline handles

aclocal.m4
	- add additional character to test for broken wcwidth (0x200b)

	- update_line: use IS_COMBINING_CHAR instead of UNICODE_COMBINING_CHAR
	  plus WCWIDTH; it doesn't make sense on systems where wcwidth isn't
	  broken

				   2/27

print_cmd.c
	- print_case_clauses: if one of the case command pattern lists begins
	  with the word `esac' (unquoted), precede the pattern list with `(',
	  since it had to be there originally to get through the parser.
	  Report by Emanuele Torre <torreemanuele6@gmail.com>

				   2/29
				   ----
general.c,general.h
	- string_to_rlimtype: takes a second ENDP argument, like strtol, so
	  the caller doesn't have to check that the string is all digits,
	  but can optionally check for and disallow a 0x prefix

				    3/2
				    ---
subst.c
	- dequote_list: unset the W_QUOTED flag in the word after dequoting it
	- parameter_brace_expand_rhs: if the word in the list returned by
	  expand_string_for_rhs has W_QUOTED set, but the string being
	  expanded was not quoted, turn on the W_QUOTED in the returned word
	  so we can potentially avoid word splitting
	- expand_word_internal: if CTLNUL is a IFS character, don't add quoted
	  null strings to istring if we're going to be word splitting, since
	  they will be treated as word delimiters

				    3/6
				    ---

	- getconf_builtin,getconf_all: changes for POSIX interp 1808 proposal
	  to allow an optional pathname argument with -a that forces its use

jobs.c
	- notify_of_job_status: don't mark terminated background jobs or stopped
	  jobs as notified in shells started to run -c command
	  From a report by Greg Wooledge <greg@wooledge.org>
	- notify_of_job_status: make the final marking the dead job as notified
	  a true catch-all so we can put a debugging message in there to see
	  if there are other missing cases
	- notify_of_job_status: don't mark terminated jobs that died due to
	  a signal the shell trapped (on the assumption that the shell
	  received the signal, too) as notified, since we don't report on it
	  in the JDEAD case if the signal is trapped

builtins/printf.def
	- PF: print an error message if printf returns an error or leaves
	  ferror(stdout) true
	  From a report by Paul Eggert <eggert@cs.ucla.edu>

				   3/14
				   ----
builtins/printf.def
	- getint: now takes an int argument and returns it if the conversion
	  overflows an int; changed callers in printf_builtin
	- getint: consolidate checks for overflow. This changes the behavior
	  if the argument overflows an intmax_t: it returns a field width of
	  0 (the overflow result) instead of -1, which changes how printf
	  behaves. This is consistent with the behavior when the argument
	  overflows an int
	- printf_builtin: change check for overflow of [LONG_MIN..LONG_MAX]
	  for %d/%i to be explicit instead of relying on integer overflow of p
	- printstr,printwidestr: print message if field width or precision
	  overflow, since we don't call printf
	- printstr,printwidestr: set field width and precision on integer
	  overflow the way we do in printf_builtin
	  From a report and patch by Paul Eggert <eggert@cs.ucla.edu>

bashtypes.h
	- PRIdMAX: move redefinition here after including inttypes.h

builtins/printf.def,examples/loadables/seq.c,examples/loadables/getconf.h
	- remove PRIdMAX redefinitions, since it's now fixed in bashtypes.h
	  From a report and patch by Paul Eggert <eggert@cs.ucla.edu>

				   3/15
				   ----
include/stdckdint.in.h,include/intprops-internal.h
	- new files, from gnulib

configure.ac
	- stdckdint.h: create in the build directory if the system doesn't
	  provide one by copying ${srcdir}/include/stdckdint.in.h; make
	  sure we don't create a new one every time, changing the timestamp

Makefile.in
	- CREATED_HEADERS: add stdckdint.h

stringlib.c,externs.h
	- substring: now takes size_t arguments for START and END

lib/sh/stringvec.c
	- strvec_create,strvec_mcreate,strvec_resize,strvec_mresize: use
	  ckd_mul to avoid size_t overflow
	- strvec_len,strvec_flush: use size_t variable as array index
	  From a report by Paul Eggert <eggert@cs.ucla.edu>

bashansi.h
	- stdbool.h: include if we have it, typedef bool as unsigned char if
	  we don't and HAVE_C_BOOL isn't defined


m4/c-bool.m4
	- autoconf check for `bool' from gnulib

configure.ac
	- include m4/c-bool.m4, call gl_C_BOOL; don't explicitly check for
	  stdbool.h using AC_CHECK_HEADERS any more

config.h.in
	- HAVE_C_BOOL: define

				   3/16
				   ----

builtins/printf.def
	- decodeprec: now decodeint, takes new arguments: a char ** that is
	  the string to parse and update, an argument saying whether or not
	  to print an error message on overflow, and an argument that should
	  be the return value on overflow; use ckd_* macros to check overflow
	- printstr, printwidestr: use a different mechanism to check overflow;
	  call decodeint to get precision and field width

braces.c
	- include stdckdint.h for the ckd_* overflow checking macros
	- mkseq: the width argument is now size_t
	- mkseq: perform overflow detection using the ckd_* macros
	- mkseq: perform zero-padding directly instead of using asprintf; the
	  sprintf family has trouble when width > INT_MAX
	- expand_seqterm: use size_t instead of int for length and width
	  variables
	  From a report and patch by Paul Eggert <eggert@cs.ucla.edu>

				   3/18
				   ----
builtins/printf.def
	- printstr,bexpand: changed size/length arguments to be size_t; changed
	  callers

subst.c
	- string_var_assignment: if the variable is a local variable at the
	  current scope, output a declare command even if there are no
	  attributes or value. Still tagged as tentative

				   3/23
				   ----
test.c
	- posixtest: takes an argument, the number of test arguments to parse
	- two_arguments,three_arguments: use advance() instead of accessing
	  and manipulating pos directly
	- posixtest,three_arguments,two_arguments: don't set pos = argc
	  directly, rely on functions to advance pos appropriately
	  Picked up from coreutils test
	- term: if we see a left paren, scan forward for a closing right paren
	  and use posixtest() if there are 1-4 arguments between the parens to
	  avoid ambiguous behavior for expressions like true -a \( ! -a \),
	  which, though it's horribly ambiguous,  a user would expect to
	  return false instead of an error message
	  Picked up from coreutils-9.2 test

				   3/25
				   ----
bashansi.c
	- HAVE_C_BOOL: prefer if defined, fall back to stdbool.h if bool isn't
	  a compiler builtin

braces.c
	- mkseq: simplify break condition

builtins/printf.def
	- decodeint: let the caller decide what to do with an overflow return,
	  don't return -1 after calling report_erange(). This will honor a
	  precision even if the field width overflows
	- printf_builtin: check for overflow when adjusting precision for
	  string length with %Q
	- printstr,printwidestr: now that the code uses decodeint, we don't
	  need to check the precision against INT_MAX

bashansi.h
	- include stddef.h if we have it, otherwise define replacements for
	  NULL and offsetof()

builtins/help.def,lib/sh/fmtulong.c,lib/sh/getcwd.c,lib/sh/makepath.c,

xmalloc.c,xmalloc.h
	- xreallocarray: implementation of reallocarray that uses xrealloc
	- sh_xreallocarray: implementation of reallocarray that uses
	  sh_xrealloc and has file and line information for error messages

lib/sh/stringvec.c
	- strvec_create, strvec_resize: rewrite in terms of xreallocarray
	- strvec_mcreate, strvec_mresize: rewrite in terms of reallocarray
	- strvec_remove, strvec_search, strvec_copy, strvec_from_word_list,
	  strvec_to_word_list: use size_t instead of int where appropriate

lib/sh/stringvec.c,externs.h
	- strvec_search: return a value of type ptrdiff_t, since size_t is
	  unsigned and we want to return -1 if not found

	  All from a report and patch by Paul Eggert <eggert@cs.ucla.edu>

test.c
	- term: change paren scan algorithm to count open and close parens so
	  we handle nested subexpressions. Still not compatible in the case
	  of something like test true -a \( ! -a \) \)

	  From a report from Grisha Levit <grishalevit@gmail.com>
	- function_substitute: only save and restore the pipestatus array if
	  we are not parsing a command, since save_parser_state saves it

parse.y,externs.h
	- decode_prompt_string: now takes an additional argument to determine
	  whether this is expanding PS[0124] or the @P transformation
	- decode_prompt_string: keep track of the (last) real prompt string

execute_cmd.c
	- execute_coproc: if MULTIPLE_COPROCS is not defined, close any old

execute_cmd.c
	- coproc_setstatus: now takes a full WAIT status word as the second

	  directly and don't use lbuf. If we try to push back more than one
	  char, we use lbuf, assuming that the caller will accommodate it

builtins/read.def
	- read_mbchar: if we read a partial multibyte character (-2) and then

lib/readline/search.c
	- make_history_line_current: change to use the same strategy to move

	- dispose_saved_search_line: remove
	- noninc_dosearch: no longer need to call _rl_unsave_saved_search_line
	  or dispose_saved_search_line; use new calling convention for
	  make_history_line_current
	- _rl_nsearch_init: don't need to call _rl_maybe_replace_line, wait
	  until we move to the history line
	- _rl_nsearch_dosearch: free the undo list unconditionally, since we
	  are committed to using the contents of rl_line_buffer as the search
	  string
	- _rl_nsearch_dosearch: if we abort because of no search string, call
	  _rl_unsave_saved_search_line and let the caller clean up
	- _rl_nsearch_dosearch: if the search fails, reset rl_point to the
	  saved point, since we will be restoring the old line
	- rl_history_search_internal: don't bother to save and restore the
	  search line, since we don't use rl_line_buffer for anything

	- zungetc: rework to use a local 16-byte buffer so we can push back
	  multiple characters whether we use read or zread
	- zread/zreadretry/zreadintr/zreadc/zreadcintr/zreadn: changed to use
	  zpopbuf to check whether we have pushed back bytes
	- zreset,zsyncfd: reset the pushback buffer indices

builtins/read.def
	- read_mbchar: handle the delimiter being part of an invalid multibyte
	  character, not just the byte that makes the multibyte character
	  invalid: keep track of where the delimiter char is in the buffer and
	  use zungetc to push back that character and everything we read
	  after it so subsequent buffered (zread) or unbuffered (read) reads
	  will return them

braces.c
	- brace_gobbler: don't mark an expression as BRACE_SEQ if we've
	  already seen a comma and marked it as BRACE_COMMA, so we treat
	  it as a comma brace expansion.
