---------
[bash-4.4 released]
9/17
----
builtins/common.c
- display_signal_list: if 0 is supplied as an argument to kill -l,
display a signal-out-of-range error. Fixes bug reported by
Martijn Dekker <[email protected]>
9/18
----
print_cmd.c
- print_heredoc_bodies: take a list of redirections, all here documents,
and print the here-document bodies including the ending delimiter,
followed by a newline
- print_redirection_list: print the heredoc headers the first time
through the list of redirections so we print them in the same left-
to-right order they're supplied; print the bodies and delimiters with
print_heredoc_bodies after we print all the redirections if we're
not printing a list of commands (printing_connection == 0). Fix for
problem reported by Isabella Parakiss <[email protected]>
- print_deferred_heredocs: don't print heredoc headers, since they're
now printed in print_redirection_list
- print_deferred_heredocs: use print_heredoc_bodies
9/20
----
builtins/mapfile.def
- readarray: update usage synopsis to include -d delim. Report and
fix from [email protected]
test.c
- test_binop: if op[0] == '-', make sure op[1] != 0 before checking
op[2] or op[3]. Fixes out-of-bounds read reported by Franco
Costantini <[email protected]>
parse.y
- cond_term: if yylval.word->word[0] == '-' make sure word[1] != 0
before checking word[2] and calling test_unop. Fixes out-of-bounds
read reported by Franco Costantini <[email protected]>
- make sure to check all instances of the return value of the
simple_command production before trying to hook redirections onto it,
since it can potentially return NULL.
Reported by Franco Costantini <[email protected]>
9/21
----
parse.y
- token_is_assignment: make sure to check that the return value from
assignment() finds the `=' we just added at index I to avoid false
positives from g=g=g=g=g=g=(). Reported by Franco Costantini
9/22
----
parse.y
- token_is_assignment: if we're not using the bash malloc (which has
guard bytes after the requested allocation size), use a new
buffer so we can make sure it's big enough to hold the current
token and at least two additional characters. Reported by
Franco Costantini <[email protected]>
9/23
----
execute_command.c
- execute_in_subshell: call without_job_control for both job control
and non-job-control builds to avoid waiting for last_made_pid
inherited from parent shell. Related to fix from 8/4 to
initialize_subshell. Fixes bug reported by Martijn Dekker
builtins/declare.def
- local_builtin: allow `local --help' to work even when not executing
a function. Suggestion from Norm Abramovitz <[email protected]>
9/25
----
builtins/printf.def
- bexpand: if passed a null or empty string, return a newly-allocated
empty string (so the return value can always be freed) instead of
NULL.
- printstr: if passed a null string, treat it as if it were an empty
string so any precision or fieldwidth arguments are handled
correctly. Report from isabella parakiss <[email protected]>
subst.c
- skip_matched_pair: make the flags argument of 1 affect whether or
not backslash can quote characters in the string, so it affects
all quoting mechanisms
arrayfunc.c
- unbind_array_element: now takes a third (flags) argument; flags&1
means to not expand an associative array index. This is only called
from a shell builtin context, which means the argument should have
already undergone word expansion, so it should be ok. Will still
be a problem for uses like "unset -v 'var[$ind]'", quoted to avoid
globbing
- valid_array_reference: pass second flags argument to skipsubscript;
still set to 0 by all callers
arrayfunc.h
- unbind_array_element: updated prototype
builtins/set.def
- unset_builtin: add third argument of 1 to unbind_array_element calls
[TEMPORARILY DISABLED]
- unset_builtin: call valid_array_reference with second arg of 1 to
handle unmatched pairs of quotes and [/]
array.c
- array_reference: optimize access locality as well as sequential
access by adding ability to start from last-accessed element and move
backwards or forwards depending on the desired index. Inspired by
report from Tom McCurdy <[email protected]> and followup from
Christian Franke <[email protected]>
variables.c
- all_array_variables: include associative arrays, not just indexed
arrays. Reported by Grisha Levit <[email protected]>
execute_cmd.c
- execute_disk_command: if we're optimizing out the fork (CMD_NO_FORK),
decrement the shell level so we don't end up incrementing it twice.
We should decrement the shell level for an implicit exec like an
explicit one. Reported by Stephane Chazelas
builtins/exec.def
- exec_builtin: don't bother to decrement the shell level if we are
already in a `(command)' subshell. Reported by Stephane Chazelas
lib/readline/macro.c
- macro_level: count of macro nesting level, maintained by
_rl_push_executing_macro and _rl_pop_executing macro
- _rl_with_macro_input: if current nesting level exceeds
MAX_MACRO_LEVEL, abort the current command line with _rl_abort_internal
and return to the top level. Reported by Christian Klomp
lib/readine/history.c
- add_history: if allocating the history list for the first time,
make sure the max history list size isn't so large that it will
cause allocation errors. Cap it at MAX_HISTORY_INITIAL_SIZE
(8192). Reported by Sean Zha <[email protected]>
jobs.c
- wait_for: if a foreground job with job control enabled is killed by a
SIGINT and sourcelevel != 0, act as if we received the SIGINT so the
file sourcing can be terminated. Reported by PePa
9/26
----
subst.c
- read_comsub: only warn once for null bytes in command substitution
output, instead of once for every null byte
arrayfunc.c
- array_variable_part: now takes a `flags' argument; changed all callers
to initially pass 0
- array_variable_name: now takes a `flags' argument; changed all callers
to initially pass 0
- array_variable_name: pass `flags' argument to skipsubscript instead
of just passing 0
arrayfunc.h
- array_variable_{name,part}: added new argument to prototypes
9/29
----
bashline.c
- bash_directory_completion_hook: don't bother to try and expand a
${ or $( that isn't complete; expand_prompt_string will complain.
Fixes reports from John Passaro <[email protected]> and
Valentin Bajrami <[email protected]>
lib/readline/history.c
- _hs_append_history_line: use a strategy that attempts to avoid
realloc copying memory to a newly-allocated block if the history
line we're appending to gets `too long' (currently 256 bytes).
We reallocate in powers of 2 starting at 512, and rely on realloc
not allocating a new block and copying into it if the size is the
same as the last call to realloc. Addresses issue raised by
Hubert Schmid <[email protected]>
trap.h
- check_signals: new extern declaration
- trapped_signal_received: new extern declaration
builtins/read.def
- read_builtin: if one of the zread* functions returns < 0 (which
usually only happens in Posix mode), make sure we call check_signals()
before eventually calling run_pending_traps() because zread() isn't
going to call it
- include trap.h for correct extern functions and variable declarations
lib/sh/zread.c
- zread: if executing a builtin, call check_signals_and_traps() for
backwards compatibility. If not, call check_signals() only, because
we don't want to run traps during, for instance, reading command
substitution output. Fixes race condition bug reported by Luiz Angelo
Daros de Luca <[email protected]>

subst.c
- command_substitute: reset parse_and_execute_level to 0 in the child
process, since it's independent of the other parse_and_execute
calls. Adds command substitution inside other parse_and_execute
calls optimizations to suppress forks, as suggested by
Martijn Dekker <[email protected]>

array.h
- array_first_index: new convenience define
array.c
- ADD_AFTER: new define, complement of ADD_BEFORE
- UNSET_LASTREF: now takes an array as an argument, prepping for move
of lastref pointer into the array struct
- array_insert: check whether we are adding at the beginning of the
array and take a fast path if so
- array_insert: use same strategy as array_reference to find the place
to insert, starting from the last-referenced element and moving
forward or back from there; use ADD_AFTER if moving backward
- array_insert: if replacing an existing element, just replace the
value with new->value instead of the entire element
- array_reference: short-circuit quickly if looking for an element
before the first assigned index
- array_reference: if we don't find the element, leave lastref pointing
to the closest element under the assumption we will be assigning or
looking for something close
- array_reference: take advantage of ordered indexes to short-circuit
when looking for element that is not set

lib/malloc/malloc.c
- internal_realloc: if we are requesting reallocation to the same size
as the block's current size, short-circuit and return `mem' right
after doing bounds check
- internal_realloc: if we are reducing the size of an allocation, and
the new size fits in the next lower bin, just keep the same block
and adjust the size, so we can avoid some copies
parse.y
- set_line_mbstate: keep track of the allocated size of
shell_input_line_property, only request reallocation if the size
increases, but don't let it get too big
10/11

jobs.c
- wait_for_background_pids: make sure we wait for pid in
last_procsub_child since it's not found in any job -- still needs
more work to wait for multiple process substitutions
subst.c
- process_substitute: if make_child fails, make sure we call
restore_pipeline to undo the previous save_pipeline()
10/15

subst.c
- process_substitute,command_substitute: leave subshell_level (reflected
as $BASH_SUBSHELL) intact for any exit trap instead of decrementing
it. Suggested by Martijn Dekker <[email protected]>
builtins/evalstring.c
- optimize_subshell_command: new function, framework for optimizing
out forks for command that have already forked and are executing
in a subshell. Not used yet
expr.c
- readtok: if we have a post-increment or post-decrement, and the
previous token is not a string, check whether the previous token is
a number that results from a pre-increment or pre-decrement, and
make that an error. Report from Conrad Hoffmann <[email protected]>

possibly multi-line command that contains a shell comment; set in
maybe_add_history and bash_add_history to either the current
command number or -2
- maybe_add_history: set current_command_line_comment for first line
of command
- bash_add_history: chars_to_add set to "\n" if the current command line
is one greater than the previous line containing a comment
(current_command_line_comment). Fixes complaint from back in
January, 2016 from Dave Rutherford <[email protected]>
array.h
- lastref: move last-referenced pointer into each array struct, so all
arrays can have reference locality
array.c

- array_copy: if copying the lastref in array a, set the new lastref
in the copy to the same element
- IS_LASTREF, LASTREF_START, LASTREF, INVALIDATE_LASTREF, SET_LASTREF,
UNSET_LASTREF: change to use new array `lastref' member
pathexp.c
- quote_string_for_globbing: if quoting for a regexp, make sure to
skip and copy a leading `^' in a bracket expression, and skip and
copy a subsequent `]' (after an optional `^'), so that leading
bracket doesn't close the bracket expression. Report from

process substitution
- extract_dollar_brace_string: add calls to CHECK_STRING_OVERRUN for

character range, check whether *p was NULL before the increment
and short-circuit the bracket expression if it is
jobs.c
- discard_last_procsub_child: new function, safely discards
last_procsub_child and sets it to NULL

execute_cmd.c
- execute_simple_command: if executing a builtin returns EX_DISKFALLBACK,
try running execute_disk_command instead
bashline.c
- shell_expand_line: use expand_word to expand the readline line
buffer, which allows us to pass flags with the word. If a numeric
argument is supplied, do not perform quote removal (pass
Q_HERE_DOCUMENT since here-doc quoting does the right thing) and
do not perform command or process subsitution. From a suggestion
by Dabrien 'Dabe' Murphy <[email protected]> based on an old bug-bash
discussion
subst.c
- expand_word_internal: note that we have added a quoted IFS char to
istring by setting sentinel has_quoted_ifs. Usually we only add
one if we are not going to be performing word splitting, but we
will not perform word splitting if there's no expansion, so we need
to take care of that case
- expand_word_internal: when performing final word split, if there are
no expansions but has_quoted_ifs is non-zero, call remove_quoted_ifs()
to remove any quoted ifs characters we added while processing
- remove_quoted_ifs: new function, removes CTLESC chars preceding
(single-byte) chars in IFS. Used when we are not performing word
splitting. Fixes bug reported by Martijn Dekker <[email protected]>

indicate that we are at the end of a keyboard macro sequence
lib/readline/rlprivate.h
- _rl_peek_macro_key: extern declaration
lib/readline/readline.c
- _rl_dispatch_subseq: add test for ESC at the end of a keyboard macro,

previous test didn't run the timeout code if executing from a macro,
even if we had read the last character of the macro. Fixes bug
reported by Clark Wang <[email protected]>

bashhist.h
- HISTEXPAND_DEFAULT: default value of history_expansion, moved here

sets; history_expansion set to value of this variable; defaults to 0
- history_expansion: now set to HISTEXPAND_DEFAULT
bashhist.c
- bash_history_reinit: if interact == 0, set history_expansion to the
value of histexp_flag, to allow -H option to enable history
expansion
- bash_history_reinit: if interact == 0, make sure
history_expansion_inhibited is set opposite of histexp_flag, so
enabling history expansion with -H invocation option turns off
inhibited expansion. If interactive shell, we turn it off so
history_expansion controls whether or not history expansion takes
place. In practice, this function is always called with interact == 0,
and -c command still doesn't perform history expansion
shell.c

identical in an interactive shell; allows both -H/+H option and
default compilation options (HISTEXPAND_DEFAULT) to work

subst.c
- get_word_from_string: take advantage of the fact that SEPARATORS is

expanding any arithmetic expression (Q_ARITH). This fixes a
backwards compatibility issue with expressions like ~0 reported by
Bize Ma <[email protected]>
subst.c
- parameter_brace_expand_indir: if the variable is not special and

group were orphaned) during the loop where we try to stop the shell
if it's not in the foreground. Not a perfect solution; the kernel
might not send SIGHUP

most before deciding we're in the background and probably a member of
an orphaned process group; set original_pgrp to the terminal's pgrp
(so the eventual give_terminal_to doesn't leave the terminal in the
wrong pgrp); and bail on job control initialization

lib/sh/shquote.c
- sh_backslash_quote: if FLAGS&2, backslash-quote other single-byte
characters that are in the current locale's <blank> character class
builtins/printf.def
- printf_builtin: when processing the `%q' format, make sure to
backslash quote all <blank> characters by making sure that FLAGS
passed to sh_backslash_quote includes 2. Fixes issue for certain
iso-8859-1 locales where character 160 (octal 240, hex 0xa0) is a
non-breaking space. Report from Stephane Chazelas

available. This is the case on some old versions of SunOS. Report
and patch from Dmitry Goncharov <[email protected]>
