12/6/2020
---------
[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

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.

builtins/exec.def
- exec_builtin: set last_command_exit_value before calling exit_shell
so any exit trap gets the right value for $?. From Matthew Bauer

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
- shtimer_unset: don't call falarm(0,0) unless the SHTIMER_ALRMSET flag

in a string for those code paths that don't expand it themselves
subst.h
- expand_string_dollar_quote: extern declaration
parse.y

arrayfunc.c
- expand_compound_array_assignment: since we run the string through

any CTLESC characters passed to expansion are part of the original
word and should themselves be quoted, doubling the number of CTLESCs

subst.c
- expand_subscript_string: allocate new memory for td.word, copying
STRING, in case it gets freed on error by expand_word_internal.
Report and fix from Koichi Murase <myoga.murase@gmail.com>
lib/malloc/malloc.c
- malloc_usable_size: return the allocated size instead of the chunk
size, since writing over the bounds checking will cause fatal errors.
Reported by Julien Moutinho <julm+bash@sourcephile.fr>, fix from
Dominique Martinet <asmadeus@codewreck.org>
arrayfunc.c
- unbind_array_elememnt: pass (flags&VA_NOEXPAND) to skipsubscript(),
instead of unconditionally passing 1 if we're operating on an
associative array. This is consistent with how valid_array_reference
determines the length of the subscript.
Report and fix from Koichi Murase <myoga.murase@gmail.com>
10/6
----
subst.c
- skip_to_delim: add a new value for FLAGS. If FLAGS&2, we assume that
START is one character after the opening OPEN. If not, we assume that
START is at OPEN, and needs to be incremented past it. Part of fix
from Koichi Murase <myoga.murase@gmail.com>
arrayfunc.c
- unbind_array_element: make sure to pass FLAGS to skipsubscript with
bit 2 set, since we are passed a SUB index that's one past the
opening bracket. Rest of fix from
Koichi Murase <myoga.murase@gmail.com>
- array_variable_name: make sure we pass (FLAGS&1) to skipsubscript, so
we don't inadvertently pass a value with bit 2 set, which would
cause an off-by-one error in subscript parsing
10/8
----
trap.c
- restore_traps: inverse of reset_signal_handlers. This understands
how reset_signal_handlers changes the signal disposition while
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
with options that start with a `+' so the attribute is off when
the assignment is performed and changes how the value is expanded.
From a report by Léa Gris <lea.gris@noiraude.net>
lib/readline/complete.c
- rl_display_match_list: even if _rl_completion_prefix_display_length
is set to a non-zero value, pass the common prefix length to
fnprint if we've turned on colored completion prefixes; passes
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
completion-prefix-display-length. From a report by
Christoph Anton Mitterer <calestyo@scientia.net>

parse.y
- parse_dparen: if the last token is FOR, increment word_top and assign
word_lineno like for other for loops. Fixes bug with LINENO after
arithmetic for commands reported by
Tom Coleman <thomas.james.coleman@gmail.com>

-----
execute_cmd.c
- shell_execve: if execve fails with ENOENT, but executable_file()
succeeds, display a slightly more descriptive error message. Prompted
by a report from Andrea Monaco <andrea.monaco@autistici.org>
stringlib.c
- strcreplace: allow backslash to escape a backslash, since we allow it
to escape a `&'
10/14
-----
pcomplib.c
- COMPLETE_HASH_BUCKETS: double to 512
stringlib.c
- strcreplace: the last argument is now a flags argument. 1 has its
previous meaning (glob); 2 means to allow backslash to escape a
backslash (as added on 10/11)
subst.c
- pat_subst: call strcreplace with 2 as the flags value

local_prompt_newlines, since that's how update_line() expects to
get it. Fix from sparrowhawk996@gmail.com.
lib/readline/macro.c
- rl_end_kbd_macro: make sure current_macro_index is > 0 after
subtracting the key sequence length, clamp it to 0 before writing
the ending NULL. From a fuzzing report by
Tillmann Osswald <tosswald@ernw.de>
lib/readline/isearch.c
- _rl_isearch_dispatch: in the bracketed paste case, don't assume the
pasted text is null-terminated, so use memcpy instead of strcpy for
the length of the pasted text, then make sure the search string is
null-terminated. From a fuzzing report by
Tillmann Osswald <tosswald@ernw.de>
lib/readline/text.c
- rl_transpose_words: make sure to preserve the value of rl_end from
the beginning to the end of the function. From a fuzzing report by
Tillmann Osswald <tosswald@ernw.de>
lib/readline/vi_mode.c
- rl_vi_delete_to,rl_vi_change_to,rl_vi_yank_to: if we are redoing a
command (_rl_vi_redoing == 1), save the old _rl_vimvcxt, allocate a
new one, and restore the old one before returning. Prevents some
pointer aliasing problems. From a fuzzing report by
Tillmann Osswald <tosswald@ernw.de>

arrayfunc.c
- tokenize_array_reference: take valid_array_reference and add a third
argument (char **SUBP), which, if non-NULL, gets the null-terminated
subscript parsed from the NAME argument. If it's NULL, the caller
gets the old valid_array_reference behavior. Fix from
Koichi Murase <myoga.murase@gmail.com>
- valid_array_reference: just call tokenize_array_reference with a
NULL third argument
- unbind_array_element: assume the caller (unset_builtin) passes a
null-terminated SUB that's already been validated by a call to
tokenize_array_reference so we don't need to call skipsubscript() or
check VA_ONEWORD. Fix from Koichi Murase <myoga.murase@gmail.com>
arrayfunc.h
- tokenize_array_reference: extern declaration
builtins/set.def
- unset_builtin: use tokenize_array_reference to figure out T and pass
that to unbind_array_element. Fix from
Koichi Murase <myoga.murase@gmail.com>
- unset_builtin: pass non-null argument to array_variable_part to get
the length of the subscript (T), then cut off any final `]' before
passing it to unbind_array_element, since that's what it now
expects
subst.c
- expand_string_for_rhs,expand_string_for_pat: assign td.word from
newly-allocated memory in case it gets freed on error during the
call to call_expand_word_internal(); free it manually when that
call returns

execute_cmd.c
- SET_LINE_NUMBER: set line_number, but don't set line_number_for_err_trap
if we're already running the ERR trap
- GET_LINE_NUMBER: evaluates to line_number_for_err_trap if we're
running the ERR trap and executing_line_number() otherwise
- execute_function: use GET_LINE_NUMBER to push the value for the line
number into the BASH_LINENO array
- execute_command_internal,execute_arith_command,execute_cond_command:
use SET_LINE_NUMBER to avoid overwriting line_number_for_err trap
while executing the ERR trap. Tentative fix for `caller' problem
reported by Quinn Grier <quinn@quinngrier.com>
configure.ac,patchlevel.h
- set bash version to 5.2-devel, meaning shell_compatibility_level = 52,
which required updating tests (array.tests, array21.sub,
quotearray3.sub, new-exp10.sub, history2.sub). The first three are
because bash-5.2 flushes an indexed array but does not unset the
variable when given `unset a[@]' or `unset[*]' (that is, it acts
like `a=()' instead of `unset a'); the other two are because the
version number changed

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

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

-----
arrayfunc.c
- array_value_internal: now takes an array_eltstate_t * as the final

`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

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

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

- 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)

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

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

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

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
capability). They set _rl_active_region_start_color and
_rl_active_region_end_color variables via functions
lib/readline/display.c
- putc_face: if setting standout mode, check for both the start color
and end color variables and output the start color string. If turning
off standout mode (normal face), output the end color string. Both
variables must be set
lib/readline/{readline.c,rlprivate.h}

_rl_active_region_end_color from _rl_term_so and _rl_term_se,
respectively; reset every time the terminal is changed
- _rl_init_terminal_io: turn off the active region for a dumb terminal

lib/readline/rlprivate.h
- _rl_history_search_pos: extern declaration
lib/readline/readline.c
- readline_internal_teardown: don't run the undo list against the
current history entry if the non-incremental search functions have
set _rl_history_search_pos to it, since it doesn't reflect the
current contents of the line buffer. Fixes issue reported by
Andreas Schwab <schwab@linux-m68k.org>

----
lib/readline/callback.c
- rl_callback_read_char: make sure _rl_eof_found is set to the value
of eof before calling the deprep terminal function, so it can do
different things based on whether the input code read EOF (or the
user entered the EOF character). From a gdb discussion started by
Andrew Burgess <aburgess@redhat.com> (still more to do, since this

PST_CONDEXPR for now). Fixes bug reported by konsolebox

2/23
----
findcmd.c,builtins/hash.def
- replace calls to is_directory with file_isdir, which only performs a
stat and doesn't do the eaccess call to check for an executable file
findcmd.c
- find_in_path_element: takes a new RFLAGSP argument, an int * where
the status flags for the returned pathname are returned; saves
additional calls to stat/eaccess
- search_for_command: get the returned flags from
find_user_command_in_path so we don't need any additional calls to
file_status after we find the command in $PATH
2/24

----
lib/readline/misc.c
- _rl_free_saved_history_line: call rl_free_undo_list, saving and
setting rl_undo_list to the saved history line's data, so the right
call to _hs_replace_history_data happens and we don't end up with
a pointer aliasing problem. Fixes core dump reported by
Andreas Schwab <schwab@linux-m68k.org>, but does not make his
scenario equivalent to incremental search
3/1
---
lib/readline/search.c
- make_history_line_current: save the current line before replacing it
with the found history entry using rl_maybe_save_line
- noninc_dosearch: we don't want the saved history line, so free it
after calling make_history_line_current
- _rl_history_search_internal: call rl_maybe_replace_line after making
changes to the line buffer with make_history_line_current so we can
save the undo list we constructed before we set the history position
3/2
---
lib/readline/display.c
- expand_prompt: add missing piece to patch from 10/26/2021: if we are
recalculating the number of invisible characters on the first line
of the prompt, we need to update INVFL, even if we already set it
when we hit the number of physical characters. This ends up being
assigned to prompt_invis_chars_first_line, and is used in several
subsequent calculations. Reported by
Andreas Schwab <schwab@linux-m68k.org>
lib/readline/doc/{readline.3,rluser.texi},doc/bash.1
- enable-bracketed-paste: add some language making it clearer that
bracketed paste prevents the pasted text from being interpreted as
editing commands. Suggested by Karl O. Pinc <kop@karlpinc.com>
3/4
---
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
- sh_charvis: now take an additional SLEN argument to avoid having to
compute the string length every time; change callers
- sh_charvis: add a utf-8 locale-specific check before calling
COPY_CHAR_I (in practice, doesn't make any real difference)
3/10

arrayfunc.c
- convert_var_to_array: if we're being asked to create an associative
array (flags & 2), and we have an existing variable that is not an
assoc array (and not an existing indexed array), call
convert_var_to_assoc to make it one
3/11

jobs.c
- wait_for: don't call get_tty_state() if readline is dispatching
(RL_STATE_DISPATCHING) with the terminal settings changed
(RL_STATE_TERMPREPPED), the same way we don't if we are running a
command for programmable completion. Fixes bug with SIGINT reverting
to the saved readline terminal settings reported by
Markus Napierkowski <markus.napierkowski@cyberus-technology.de>
parse.y
- decode_prompt_string: make sure the expansion of \w, \W, and \s
are all run through sh_strvis before calling
sh_backslash_quote_for_double_quotes or just through sh_strvis if
we're not running the prompt string through word expansions.
Fixes issue reported by Josh Harcome <joshharc@gmail.com> back
in mid-January
3/16
----
bashline.c
- bash_quote_filename: if we have a word to complete that contains
characters that introduce a word expansion, make sure the passed
string does *not* exist as a filename before removing those
characters from the set that must be backslash-quoted. See change
from 1/1/2022
3/18

lib/readline/search.c
- make_history_line_current: don't free rl_undo_list or
_rl_saved_line_for_history; don't unconditionally save the history
line. This reverts some of the changes to support setting the
history position in history-search-backward
- rl_history_search_internal: only free the saved history line if we
were the ones who created it
3/21

lib/readline/nls.c
- xmalloc.h: include for systems without setlocale(), so xfree has a
prototype. Report and fix from András Kucsma <r0maikx02b@gmail.com>
lib/readline/search.c
- _rl_history_search_internal: use previous-history/next-history to
move to the found history line instead of directly calling
history_set_pos. This makes the behavior more similar to incremental
search
- rl_history_search_internal: make sure to set rl_undo_list to the
current history undo list around the calls to rl_get_previous_history
or rl_get_next_history, in order to fool the call to
maybe_replace_line they make
lib/readline/readline.c
- _rl_executing_func: the currently-executing readline command function
lib/readline/rlprivate.h
- _rl_executing_func: extern declaration
lib/readline/search.c
- _rl_history_search_internal: removed (commented out) code that sets
the current history entry to the found history entry, too much
assumes that the current undo list should be applied to the current
history entry (where_history())
3/23

subst.c
- parameter_brace_expand_word: if we have double-quoted ${*} or ${@},
make sure we are setting W_HASQUOTEDNULL in the flags we return to
the caller if we are returning QUOTED_NULL(word)
- parameter_brace_expand_word: if we have a double-quoted associative
array reference using `*' or `@', make sure we are setting
W_HASQUOTEDNULL in the flags we return to the caller if we are
returning QUOTED_NULL(word)
- parameter_brace_expand: if we're using the `[:]+' word expansion
operator, we need to note a quoted null string and pass the
W_QUOTEDNULL flag back to the caller
- expand_word_internal: make sure to return a QUOTED_NULL
(word[0] == CTLNUL) back to the caller if HAD_QUOTED_NULL is set,
regardless of whether or not we see a quoted dollar at. Fix for bug

variables.c
- unbind_global_variable, unbind_global_variable_noref: new functions
that remove variables from the global_variables table
lib/sh/shmatch.c
- sh_regmatch: use unbind_global_variable_noref to make sure we act on
the copy of BASH_REMATCH in the global scope all the time, ignoring
any local variables that might exist. Tentative fix for memory leak

print_cmd.c
- print_redirection: if the redirectee for r_duplicating_output_word
(r_duplicating_input_word) is 1 (0), don't print it; only print a
non-default file descriptor number
- print_redirection_list: remove the code that tries to temporarily
translate a >&word redirection to >&word now that we won't print a
non-default file descriptor number. Fixes issue with `declare -f' and
function export reported by Namikaze Minato <lloydsensei@gmail.com>

execute_cmd.c
- {execute_cond_node,execute_arith_command,eval_arith_for_expr}: make
sure to reset this_command_name after running any DEBUG trap so the
DEBUG trap doesn't overwrite it.

- execute_select_command: set this_command_name to NULL after running
any DEBUG trap like execute_for_command does

subst.c
- expand_word_internal: when expanding backquoted command substitution,
call string_extract with the SX_REQMATCH flag (closing backquote
required) only if the word flags don't contain W_COMPLETE,
indicating that we're doing this for completion, probably to
determine whether or not to append something to the word. Fixes bug
reported by Emanuele Torre <torreemanuele6@gmail.com>.

execute_cmd.c
- execute_connection: treat a connector of '\n' the same as ';'
print_cmd.c
- print_comsub: new function, sets flag noting we are printing a
command substitution and calls make_command_string
- make_command_string_internal: add '\n' to the ';' case; print command
list with newline connector appropriately
parse.y
- parse_comsub: call print_comsub instead of make_command_string
- list1 production (part of compound_list): if a list is separated by
newlines, and the parser is parsing a command substitution, make
the connection command with a '\n' connector. Makes the text
output of parse_comsub closer to the original source text. From a
report from Martijn Dekker <martijn@inlv.org>

builtins/setattr.def
- show_local_var_attributes: special-case `local -', since there is
no `declare -' equivalent.
Reported by Emanuele Torre <torreemanuele6@gmail.com>.
- show_all_var_attributes: use `local -' when printing a variable named
`-' at the current non-zero variable context
parse.y
- shell_getc: if we are at the end of an alias, returning a space,
make sure we mark the previous character as single-byte by modifying
shell_input_line_property so the space we return is properly
recognized. This would fail before if the last character of the
alias was a multi-byte character. Reported by

jobs.c
- set_job_control: don't bother calling tcgetpgrp if shell_tty < 0,
since it will just fail
variables.c
- reset_local_contexts: new function, delete all context tables
associated with shell functions and set variable_context to 0.
Called when we want to stop executing in a shell function without
going through the pop_context chain with its side effects
variables.h
- reset_local_contexts: extern declaration
builtins/evalstring.c
- parse_and_execute: call reset_local_contexts instead of setting
variable_context to 0
eval.c
- reader_loop: call reset_local_contexts in cases where the shell has
longjmped for a fatal error and errexit is enabled (ERREXIT), but
not for other cases, and especially not for the exit builtin,
instead of just setting variable_context to 0. Fixes issue originally
reported by Robert Stoll <robert.stoll@tegonal.com>
subst.c
- pat_subst: implement sed-like behavior when presented with a null
pattern that's anchored at the start or end of the string, or when
presented with a null string: process the replacement string for `&'
and `\&' and substitute in the result as before. Patch from

parse.y
- reset_parser: set need_here_doc, esacs_needed_count, expecting_in_token
all to 0, since jumping back to a top-level parse needs that
- parse_comsub: make sure to reset expand_aliases and shell_eof_token
if we're not going to exit immediately out of this function
7/28
----
parse.y
- parse_comsub: if the compatibility level is <= 51, set extglob while
parsing the command substitution, so bad pattern errors can still be
caught but valid patterns are let through and can be evaluated at
runtime, when extglob may have been set. If it isn't set, it will
still be a parser error when the command substitution is executed.
Fixes report from Sam James <sam@gentoo.org> about gentoo scripts.
- reset_parser: set extended_glob from global_extglob if the parser
state includes PST_CMDSUBST
- xparse_dolparen: set global_extglob but don't modify extended_glob,
so parse errors can be caught before forking a child for command
substitution, as part of word expansion, but after extglob may have
been set by command execution (e.g., in a shell function)

trap.c
- run_pending_traps: move code from evalstring() so we call
parse_and_execute() directly and handle any `return' invocations so
we can restore the value of running_trap. Otherwise, if we longjmp
past this function, we will think we're running a trap after we
finish. Prompted by post from Koichi Murase <myoga.murase@gmail.com>

lib/readline/nls.c
- _rl_current_locale: private variable, stores the value of the
LC_CTYPE locale category, as determined by _rl_init_locale; set
to allocated memory in _rl_init_locale()
- _rl_set_localevars: new function, code from _rl_init_eightbit that
checks the current locale (passed as an argument) and sets the
various locale-aware variables based on it. It accepts a second
argument: FORCE. If non-zero, it means to restore the default "C"
locale values if the locale is "C" or "POSIX", now that this
function can be called multiple times
- _rl_init_eightbit: now just calls _rl_init_locale and
_rl_set_localevars
- _rl_reset_locale: new function, checks whether our the locale has
changed since we last called _rl_init_locale to set our internal
idea of its value. If it has changed, call _rl_set_localevars with
the new locale and a FORCE argument of 1 to change the
locale-dependent variables.
lib/readline/rlprivate.h
- _rl_reset_locale: extern declaration
lib/readline/readline.c
- rl_initialize: call _rl_reset_locale instead of _rl_init_locale so
the internal readline variables get set when we move from a non-
multibyte locale ("C") to a multibyte one ("en_US.UTF-8"). Report
from Alan Coopersmith <alan.coopersmith@oracle.com>

lib/sh/setlinebuf.c
- sh_setlinebuf: allocate buffers for line-buffering stdout and stderr
only once, the first time it is requested. Only allocate memory if
we're using setvbuf (we usually are). Double the buffer size to 2016
if we're using the bash malloc. Otherwise, let stdio handle it.

parse.y
- parse_comsub: restore extended_glob to a local copy (local_extglob)
only if we changed it; a safer way to do it. Fixes extglob change
issue reported by Kerin Millar <kfm@plushkava.net>
- cond_term: restore extended_glob to a local copy; safer than using
global_extglob, which we will reserve for error recovery

parse.y
- parse_comsub: don't clear the pushed string list; we might need it to
consume additional input to satisfy this command substitution. When
we restore the parser state, don't restore the pushed string list in
case we used it. From
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1018727
- parse_comsub: don't modify extended_glob if parser_state includes
PST_EXTPAT, in which case we've already set extended_glob and
global_extglob appropriately. Only matters in compatibility mode.
