This document details the changes between this version, bash-5.1-beta, and
the previous version, bash-5.1-alpha.
1. Changes to Bash
a. Fixed a bug that caused name references to variables to not update the
referenced variable's assignment side effects.
b. Tightened up the parameter transformation error checking for invalid
transformation operators.
c. System-specific changes for: FreeBSD
d. A few minor changes to move potential uses of stdio functions out of signal
handling paths.
e. Make sure SIGCHLD is blocked in all cases where waitchld() is not called
from a signal handler.
f. Changed `command' builtin processing so it no longer starts an extra process
when run asynchronously (command x &).
g. Avoid performing tilde expansion after `:' in words that look like assignment
statements when in posix mode.
h. Slight changes to how the `complete' builtin prints out options and actions
for completion specifications.
i. Several changes to how `local -' restores the values of options and
$SHELLOPTS.
j. Don't treat a word in a compound assignment as an assignment statement
unless it has a valid subscript before the `='.
k. Fixed a bug with the DEBUG trap and process substitution that caused the
terminal's process group to be set incorrectly.
l. Fixed a bug that left readline's signal handlers installed while running a
shell command from a bindable readline command.
m. Fixed the `fc' builtin to clamp out of range history specifications at the
boundaries of the history list for POSIX conformance.
n. Fixed a bug that caused ${foo@a} to treat foo as an unset variable if it
was an array without a value for subscript 0/"0" but had other set
elements.
o. Fixed a bug that caused the history code to attempt to parse command
substitutions looking for shell comments before adding them to the history,
even while parsing here-documents.
p. Fixed a bug that could cause a syntax error in a command read by `eval' to
exit an interactive shell.
2. New Features in Bash
a. If the hash builtin is listing hashed filenames portably, don't print
anything if the table is empty.
b. GLOBIGNORE now ignores `.' and `..' as a terminal pathname component.
c. Bash attempts to optimize away forks in the last command in a function body
under appropriate circumstances.
d. The globbing code now uses fnmatch(3) to check collation elements (if
available) even in cases without multibyte characters.
e. The `fg' and `bg' builtins now return an error in a command substitution
when asked to restart a job inherited from the parent shell.
f. The shell now attempts to unlink all FIFOs on exit, whether a consuming
process has finished with them or not.
3. Changes to Readline
a. Make sure that all undo groups are closed when leaving vi insertion mode.
b. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
the motion command doesn't have any effect.
c. Fixed several potential memory leaks in the callback mode context handling.
d. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
executing the terminal cleanup code, since it's no longer run in a signal
handling context.
4. New Features in Readline
a. The signal cleanup code now blocks SIGINT while processing after a SIGINT.

correctly in the C or POSIX locale.
s. Fixed a bug with vi-mode digit arguments that caused the last command to be
set incorrectly. This prevents yank-last-arg from working as intended, for
example.

lib/readline/vi_mode.c

leaving insert mode, so we don't have anything dangling.

---
lib/readline/vi_mode.c

since other code checks that and we want to allow users to rebind
this function

lib/readline/signals.c
- _rl_handle_signal: block SIGTTOU while handling a SIGTTOU, since we
no longer run this in a signal handling context where SIGTTOIU would
be blocked

execute_cmd.c
- execute_simple_command: use new variable `cmdflags' instead of using
simple_command->flags directly; initialize from simple_command->flags
- check_command_builtin: take a simple command list of words starting
with `command' and including a command_word argument, and peel off
the `command' and any instances of `-p' and `--' and return the
updated list
- execute_simple_command: if the first word of the simple command is
`command', call check_command_builtin to peel off any `command' and
`-p' and `--' and go on to execute the rest of the words as a simple
command. If we're in posix mode, we've got the special builtins
handled before this runs. Fixes complaint about `command' in the
background running an extra bash process from Dmitry Alexandrov

posix mode or W_TILDEEXP is set before turning on W_ITILDE. The old
code would turn it on unconditionally if the W_ASSIGNMENT flag was
set. Fixes bug reported by OÄuz <oguzismailuysal@gmail.com>

builtins/complete.def
- replace macros used to print compspec actions, options, and other
info with a small set of functions that traverse the structs used
to hold that information and print everything instead of eumerating
each option and action separately. From a patch submitted by
Martin Kealey <martin@kurahaupo.gen.nz>

values of shell options saved by `local -' by calling set_shellopts().
Report from Grisha Levit <grishalevit@gmail.com>
flags.c
- reset_shell_flags: set histexp_flag to 0 and let bash_history_reinit
take care of setting history_expansion appropriately. Report and fix
from Grisha Levit <grishalevit@gmail.com>
7/28
----
general.c
- assignment: if (FLAGS & 1), we are parsing the contents of a compound
assignment, and a word must begin with a `[' and have a valid
subscript terminated by `]' before the `=' to be considered an
assignment statemen and subsequently expanded like one. Report from
Alexey Izbyshev <izbyshev@ispras.ru>
7/30
----
lib/glob/sm_loop.c
- BRACKMATCH: if the bracket expression is matching simple characters
and not a range, compare the character from the string and the
pattern directly, as required by Posix interp 948
lib/glob/smatch.c
- charcmp_wc: split off code that calls wcscoll from rangecmp_wc,
just return the results of wcscoll
- rangecmp_wc: call charcmp_wc and impose a total ordering
by performing a byte comparison (or wint_t comparison) of C1 and C2
as required by Posix interp 948 (charcmp_wc takes care of the
behavior of FORCECOLL)
- collequiv_wc: call charcmp_wc instead of rangecmp_wc
- charcmp: character comparison code from rangecmp
- rangecmp: call charcmp and impose total ordering as required by
Posix interp 948
- collequiv: call charcmp instead of rangecmp
- _fnmatch_fallback: ASCII version of fallback for equivalence classes
when there are no multibyte characters in the pattern; just calls
fnmatch with a reconstructed equivalence class pattern
- collequiv: call _fnmatch_fallback if charcmp returns non-zero and
the configure check indicates fnmatch has character class support.
Fixes issue reported by Harald van Dijk <harald@gigawatt.nl>

lib/readline/signals.c
- _rl_handle_signal: since we're not called in a signal handler context
any more, we don't need to explicitly unblock the signal we received
so the application's signal handler will get it when we resend the
signal to ourselves. It doesn't hurt anything to do it, but we don't
have to
- _rl_handle_signal: Set up a framework for any signals that need to
be blocked during cleanup: add the signal to SET (initialized to the
existing set of blocked signals) and set BLOCK_SIG to 1. We block
that set around the call to rl_cleanup_after_signal().
- _rl_handle_signal: on AIX, if the signal is SIGHUP, make sure we
block SIGHUP while running rl_cleanup_after_signal()
8/3
---
jobs.c
- start_job: don't allow `fg' or `bg' in a command substitution to
attempt to start a parent's jobs. Suggested by OÄuz
<oguzismailuysal@gmail.com>
builtins/set.def
- set_current_options: only call change_flag or SET_BINARY_O_OPTION_VALUE
if the value has changed from what is stored in the bitmap, to avoid
any side effects from setting the options and save time on any
unnecessary function calls. Inspired by report from Grisha Levit
<grishalevit@gmail.com>
parse.y
- xparse_dolparen: before we jump to top level, check whether we are
still reading from the string (we might have run all the unwind-
protects) and turn off PST_CMDSUBST if we are not. Fixes fuzzing
bug reported by Jakub Wilk <jwilk@jwilk.net>
8/4
---
subst.c
- process_substitute: set subshell_environment to include SUBSHELL_ASYNC
in the child process, since we passed FORK_ASYNC to make_child. Fixes
DEBUG trap problem reported by Jonathan Rascher <jon@bcat.name>
subst.c
- unlink_all_fifos: new function, just unconditionally closes and
unlinks (if using FIFOs) each pipe used for process substitution.
There is an open to unblock any child processes sleeping on the
FIFO first. Inspired by a suggestion from "CHIGOT, CLEMENT"
<clement.chigot@atos.net>
shell.c
- exit_shell: call unlink_all_fifos() instead of unlink_fifo_list()
sig.c
- termsig_handler: call unlink_all_fifos() instead of
unlink_fifo_list()
8/5
---
arrayfunc.c
- quote_compound_array_list: turn empty strings into '' instead of
leaving them unmodified. Fixes bug in changes from 4/29 reported
by andy_bash <andy_bash@objectmail.com>
8/10
----
bashline.c
- edit_and_execute_command,bash_execute_unix_command: restore the bash
signal handlers before running parse_and_execute() so bash will catch
and handle signals, instead of letting readline catch them without
any opportunity to run _rl_handle_signal(). Fixes bug reported by
Stan Marsh <gazelle@xmission.com>
8/11
----
builtins/fc.def
- fc_gethnum: return HIST_INVALID for -0 if not in listing mode
- fc_builtin: throw an out-of-range error if histbeg or histend gets
set to HIST_INVALID
- fc_builtin: don't throw errors for other out-of-range history
specifications, clamp them at the beginning or end of the history
list, as appropriate, per POSIX. Report and fix from Martijn Dekker
<martijn@inlv.org>
8/12
----
builtins/fc.def
- fc_gethnum: return HIST_NOTFOUND (new error) if the string is not a
number and doesn't correspond to any command in the history list
- fc_builtin: print a "no command found" error message if fc_gethnum
returns HIST_NOTFOUND
8/14
----
flags.c
- no_invisible_vars: removed undocumented `-I' flag
{flags,variables}.c,flags.h,builtins/{declare,setattr.def}
- no_invisible_vars: remove all references
command.h
- PF_ALLINDS: new flag, means to expand an array variable name without
a subscript as if it were subscripted by `@' instead of `0'
subst.c
- parameter_brace_expand_word: if PFLAGS contains PF_ALLINDS, expand
an array variable name as if it were subscripted by "@" instead of
0/"0": a string with the element values separated by " ". Little
nuance; we're just interested in whether or not there are any
values at all
- parameter_brace_expand: if we are expanding something like ${foo@a},
pass PF_ALLINDS to parameter_brace_expand_word and
parameter_brace_expand_indir so we don't get tripped up on `nounset'
if foo has an assigned subscript other than 0/"0". Inspired by a
report from Andrew Neff <andrew.neff@visionsystemsinc.com>
8/17
----
bashhist.c
- bash_add_history,maybe_add_history: don't need to call shell_comment
if we are in the middle of adding a here-document, since it may
call the parser recursively on data that is not guaranteed to be
valid input. From a report by Hyunho Cho <mug896@gmail.com>
8/24
----
lib/readline/complete.c
- compare_match: compare TEXT from the line buffer and MATCH, a
possible completion for TEXT, after dequoting TEXT if necessary
- rl_complete_internal,rl_menu_complete : if show-all-if-unmodified is
set, use compare_match instead of a straight strcmp to determine if
the match has changed the text to complete, so we can use it for
filenames that require quoting. Report and pointer to fix from
Abon B <gnuabonbon@gmail.com>
8/25
----
eval.c
- execute_prompt_command: PROMPT_COMMAND can now be an array, subsuming
PROMPT_COMMANDS, which bash no longer looks for. Prompted by a
suggestion from Martijn Dekker <martijn@inlv.org>
8/26
----
builtins/fc.def
- fc_gethnum: now takes a flags word as the third argument, with two
current flag values: HN_LISTING, which means we are listing history
entries, and HN_FIRST, which means we are parsing the first in a
first,last range of history entries
- fc_gethnum: if we have a number >= 0, and it's out of range, return
different values (0 or last history) depending on whether we are
parsing the first or last in a range argument. Based on a report from
Martijn Dekker <martijn@inlv.org>
8/31
----
parse.y
- grammar: call handle_eof_input_unit from the eof-after-error
production only from interactive top-level shells, so a syntax error
in `eval' doesn't exit an interactive shell. Report and fix from
Koichi Murase <myoga.murase@gmail.com>
bashline.c
- bash_execute_unix_command: if we call parse_and_execute with allocated
memory, make sure not to include SEVAL_NOFREE in the flags so it will
free that command string before returning. Report and fix from
Koichi Murase <myoga.murase@gmail.com>
array.[ch]
- array_to_argv: now takes a second argument: COUNTP; returns the number
of elements stored in the strvec
- array_to_argv: don't store array elements with null values; it makes
it hard for callers to walk the whole array reliably
pcomplete.c
- gen_shell_function_matches: change call to array_to_argv
array.h
- execute_array_command: now takes the entire ARRAY * as the first
parameter
eval.c
- execute_array_command: now takes the entire array, puts the elements
into a strvec, and executes each element of the strvevc as a command.
This protects against a command from PROMPT_COMMAND[n] unsetting the
corresponding element of PROMPT_COMMAND.
From a report from Koichi Murase <myoga.murase@gmail.com>
