[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

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

jumps back to the top level. A shell compiled with -DSTRICT_POSIX
exits unconditionally.

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

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

it changes later for alignment

- enable-active-region: separate control of the active region and
bracketed paste. Still set to the same default value as bracketed
paste, and enabling bracketed paste enables the active region.
Now you can enable bracketed paste and then turn off the active
region.

with subscript, replaces W_DOLLARSTAR, which was unused
subst.c
- expand_subscript_string,expand_array_subscript: new functions to
parse and expand-and-quote array subscripts. For future use

builtins/mapfile.def
- mapfile: if the delimiter is a newline, set unbuffered_read = 1
for any file descriptor that isn't seekable and lseek sets errno
to ESPIPE (pipes, FIFOs, maybe terminal devices). If it's not a
newline, only allow buffered reads if the file descriptor is a
regular file. Report from Koichi Murase <myoga.murase@gmail.com>
builtins/read.def
- read_builtin: only set unbuffered_read = 1 if the input is coming
from a pipe (which we can't seek on) or the input is a terminal and
we want to read a specified number of characters or we're using a
non-standard delimiter

- mapfile: call zsyncfd before calling the callback. Suggested by
Koichi Murase <myoga.murase@gmail.com>; we'll see how it goes

subst.h
- expand_subscript_string: extern declaration
{arrayfunc,subst}.c
- expand_subscript_string: replace expand_assignment_string_to_string
with calls to this when expanding array subscripts
