+[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 OÄuz <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

+ 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.

+make_cmd.c
+ - make_here_document: perform quote removal on the here-doc delimiter
+ only if it's marked as quoted, which prevents quotes from inside a
+ command substitution from being removed (they're supposed to begin a
+ new quoting context) when the word itself isn't flagged as quoted
+ (which means the body of the here-document gets expanded). You can't
+ perform quote removal *and* expand the here-document lines. From an
+ austin-group discussion back in early February
+
+lib/sh/strvis.c
+ - charvis -> sh_charvis; change caller
