Raw Blame History

7/27/2004
---------
[bash-3.0 released]
7/28
----
array.c
- in array_insert(), make sure the value to be added is non-NULL before
calling savestring() on it
builtins/reserved.def
- fix description of `CDPATH'
lib/readline/display.c
- when expanding a prompt that spans multiple lines with embedded
newlines, set prompt_physical_chars from the portion after the
final newline, not the preceding portion. Bug reported by
"Ralf S. Engelschall" <rse@engelschall.com>
make_cmd.c
- explicitly declare `lineno' in function prologue for make_case_command
builtins/evalfile.c
- include `trap.h' for declaration for run_return_trap
bashline.c
- fix a `return' without a value in enable_hostname_completion
general.c
- include test.h for extern declaration for test_eaccess
externs.h
- add declaration for zcatfd
tests/{history,histexp}.tests
- unset HISTFILESIZE to avoid problems if a value of 0 is inherited
from the environment
7/30
----
bashline.c
- small changes to glob_expand_word to perform tilde expansion before
attempting globbing
builtins/Makefile.in
- fix the install-help target to not cd into the `helpfiles'
subdirectory, so a value of $INSTALL_DATA containing a relative
pathname (e.g., .././support/install.sh) remains valid
7/31
----
subst.c
- new function, mbstrlen(s), returns length of a multibyte character
string
include/shmbutil.h
- new macro, MB_STRLEN(s), calls mbstrlen or STRLEN as appropriate
builtins/trap.def
- small change so that a first argument that's a valid signal number
(digits only -- no symbolic names) will be treated as a signal and
reverted back to the original handling disposition. Fixes debian
complaints
subst.c
- call MB_STRLEN instead of STRLEN where appropriate in
parameter_brace_expand_length to handle multibyte characters properly
- call MB_STRLEN instead of strlen in verify_substring_values so that
negative substrings of strings with multibyte chars work properly
8/1
---
jobs.c
- describe_pid needs to write to stderr, not stdout (POSIX)
- start_job, since it's only used by builtins (fg/bg), needs to write
its output to stdout, not stderr (POSIX)
sig.c
- add an `orig_flags' member to struct terminating_signal so the
original signal handling flags (SA_RESTART, etc.) can be preserved
on POSIX systems
- make sure to preserve the signal flags state in
initialize_terminating_signals and reset them for child processes
in reset_terminating_signals
builtins/fc.def
- fixed an off-by-one error that caused `fc -l' to list one too many
history entries
- in posix mode, `fc' should not list any indication as to whether or
not history lines have been modified (POSIX)
- when in posix mode, the default editor for `fc' should be `ed' (POSIX)
doc/bashref.texi
- updated the description of `trap' behavior when given a first
argument that is a valid signal number
- noted that `fc -l' won't indicate whether a history entry has been
modified if the shell is in posix mode
builtins/command.def
- fixed bug: `command -v' is supposed to be silent if a command is not
found
builtins/hash.def
- `hash' should print its `hash table empty' message to stderr
lib/readline/misc.c
- back out 7/7 change to _rl_maybe_save_line; it breaks emacs-mode ^P
general.c
- changed base_pathname so that it will return reasonable results for
non-absolute pathnames -- this is what is intended by all of its
callers
arrayfunc.c
- fix array_variable_part to return NULL if it finds an invisible
variable in the hash table. Fixes seg fault caused by referring to
unset local variable using array notation
{locale,variables}.c
- support LC_TIME as a special locale variable so HISTTIMEFORMAT tracks
the current locale
8/2
---
variables.c
- fixed small memory leak in makunbound() when a local array variable
is unset. Fix from William Park
lib/readline/display.c
- fixed a problem when computing the number of invisible characters on
the first line of a prompt whose length exceeds the screen width
(should only happen when invisible characters occur after the
line wrap). Bug reported by agriffis@gentoo.org
builtins/command.def
- `command -V' passes a new flag, CDESC_ABSPATH, which means to convert
to an absolute path
builtins/type.def
- in posix mode, `type' and `command -v/-V' should not report
non-executable files, even if the execution code will attempt to
run them. Other posix shells do this
doc/bashref.texi
- add note to POSIX Mode section describing behavior of type and command
when finding a non-executable file
execute_cmd.c
- force extended_glob to 1 before calling binary_test in
execute_cond_node so that the right extended pattern matching gets
performed
8/3
---
braces.c
- make sure lhs[0] and rhs[0] are cast to `unsigned char' so chars
with values > 128 are handled correctly
builtins/printf.def
- change bexpand() and printstr() to handle strings with a leading
'\0' whose length is non-zero, since that's valid input for the
`%b' format specifier
subst.c
- fix a couple of instances of find_variable that didn't check the
result for an invisible variable
variables.c
- BASH_ARGC, BASH_ARGV, BASH_SOURCE, BASH_LINENO no longer created as
invisible vars
pcomplete.c
- make sure COMP_WORDS is not invisible when bind_comp_words returns
- ditto for COMPREPLY in gen_shell_function_matches
8/4
---
braces.c
- fix problem where ${ was ignored but did not increment the open
brace count. Bug reported by Tim Waugh <twaugh@redhat.com>
variables.c
- if make_local_variable finds a variable in the correct context in
the right variable scope, make sure it's not invisible before
returning it
8/5
---
builtins/trap.def
- fixed usage message to show `action' as not optional, though it
actually is when not in posix mode (for a single argument)
8/7
---
configure.in
- kfreebsd-gnu has had its sbrk() problems fixed, and no longer needs
to be configured --without-gnu-malloc
lib/readline/vi_mode.c
- in rl_vi_search, free any saved history line before starting the
search, so failure leaves you at that line, not the last line in
the history (assuming the current line is not the last history line).
Fix from llattanzi@apple.com to replace fix of 7/7
8/9
---
support/Makefile.in
- renamed `mostly-clean' target to `mostlyclean'
8/11
----
lib/readline/vi_mode.c
- make same change for EOL in multibyte character case of
rl_vi_change_char
8/12
----
subst.c
- in verify_substring_values, fix off-by-one error checking bounds of
`offset', esp. in array values (e.g., getting the highest element
of an array)
8/16
----
aclocal.m4
- change BASH_CHECK_DEV_FD to make sure that file descriptors > 2 are
accessible via /dev/fd, unlike FreeBSD 5.x
lib/sh/strftime.c
- make sure `zone' is initialized with gettimeofday before it is used
- work around HPUX lack of `altzone' and differing definitions of
`timezone'
lib/malloc/malloc.c
- internal_memalign and memalign now take a `size_t' as their first
argument, which seems to be the prevailing standard
lib/malloc/{malloc.c,shmalloc.h}
- change sh_memalign to take a `size_t' as its first argument
builtins/echo.def
- if posixly_correct and xpg_echo are both set, don't try to interpret
any arguments at all, as POSIX/XOPEN requires (fix inspired by Paul
Eggert)
doc/bashref.texi
- amend description of bash posix mode to include new echo behavior
builtins/fg_bg.def
- allow bg to take multiple job arguments, as posix seems to specify,
placing them all in the background, returning the status of the last
one as the status of `bg'
lib/readline/vi_mode
- fix _rl_vi_change_mbchar_case (multibyte-char version of `~'
command) to have the right behavior at EOL -- handle case where vi
mode backs up at the end of the line
8/18
----
array.c
- check for an empty array in array_rshift before shifting elements
and adjusting max_index
- check for null array in array_subrange
jobs.c
- fix raw_job_exit_status to not ignore exit status of the last
process in the pipeline when `set -o pipefail' is enabled
8/19
----
lib/readline/mbutil.c
- make sure _rl_find_next_mbchar_internal has a valid multibyte
character before it checks whether or not it's a zero-width
wide character and adjusts point accordingly
8/24
----
bashline.c
- new function, bash_directory_expansion, duplicates the expansions
performed on the directory name by rl_filename_completion_function
- call bash_directory_expansion in command_word_completion_function
if we decide we're doing tilde expansion (and any other
canonicalization) on the directory name being completed
8/25
----
configure.in
- use new-style AC_CHECK_HEADER to check for sys/ptem.h (which requires
sys/stream.h). The correct checks are in the code, but autoconf
complains if sys/stream.h is not included, rather than simply
checking for the header's presence
8/26
----
builtins/hash.def
- fix a bug that prevented `hash -d' from working right (as soon as
hash removed a command from the table, the bug caused it to be added
right back)
8/27
----
doc/{bash.1,bashref.texi}
- explicitly note that conditional primaries that operate on files
operate on the targets of symbolic links rather than the links
themselves
8/30
----
lib/readline/display.c
- fix multibyte calculation of `physchars' in prompt expansion, to
handle double-width multibyte characters correctly
- changes to rl_redisplay to handle prompts longer than the screenwidth
that might contain double-width multibyte characters. Fixes from
Tomohiro Kubota
9/6
---
subst.c
- change word_list_split to avoid really bad behavior caused by calling
list_append for each split word -- as the list gets long, you have
to traverse it every time. Keep a pointer to the end of the list and
and just tack onto it
9/8
---
lib/readline/complete.c
- change fnprint to calculate the displayed width of a filename in
the same way as fnwidth
subst.c
- in verify_substring_values, when expanding ${array[@]:offset}, make
sure negative offsets count from one greater than the array's
maximum index so things like ${x[@}: -1} work to give the last element
(requires fixing array tests)
builtins/common.c
- new error function, sh_wrerror(), for builtins to call when a write
error occurs
builtins/common.h
- extern declaration for sh_wrerror()
builtins/cd.def
- change builtin_error call to use sh_wrerror()
builtins/echo.def
- report write errors with sh_wrerror() instead of just returning
failure
builtins/printf.def
- change printstr to return failure (-1) or success (0) indication
rather than void
- report write errors when printstr() fails, return failure
- if any of the PF/printf calls fail, report write error and return
failure
execute_cmd.c
- change execute_in_subshell so the subshell command inherits the
command timing flags from the enclosing COMMAND *
9/11
----
[prayers for the victims of 9/11/2001]
lib/sh/strnlen.c
- new file, implementation of GNU libc extension function strnlen
lib/sh/Makefile.in, {config.h,configure,Makefile}.in, MANIFEST
- changes for strnlen
configure.in
- version changed to 3.1-devel
doc/bash.1, lib/readline/doc/rluser.texi
- added description of `-o plusdirs' to complete/compgen (thanks,
Arnold)
parse.y
- new parser_state flag, PST_ASSIGNOK, if set indicates we're parsing
arguments to a builtin that accepts assignment statement arguments
- turn on PST_ASSIGNOK in read_token_word when appropriate
- turn off PST_ASSIGNOK in read_token when appropriate
- don't attempt to parse a compound assignment specially unless we're
in a position where an assignment statement is acceptable, or
PST_ASSIGNOK is set
9/13
----
variables.c
- make BASH_ARGC, BASH_ARGV, BASH_LINENO, and BASH_SOURCE
non-unsettable, since the shell uses those values internally
expr.c
- make exponentiation right-associative, as is apparently correct
9/16
----
arrayfunc.c
- make sure convert_var_to_array marks the environment as needing
recreation if the converted variable was exported
9/17
----
braces.c
- mark ${ as introducing an additional level of braces only if it's
not in a quoted string -- quoted strings are handled before brace
matching is done
parse.y
- fixed an obscure problem in history_delimiting_chars where the `in'
in a case statement could have a semicolon added after it, if the
`case word' was on a previous line
support/config.guess
- support for newest versions of tandem non-stop kernel
lib/readline/display.c
- in compute_lcd_of_matches, explicitly cast `text' to `char *' before
passing it to rl_filename_dequoting_function
lib/readline/terminal.c
- bind the key sequence sent by the keypad `delete' key to delete-char
(same as ^D in emacs mode)
builtins/ulimit.def
- in print_all_limits, don't print anything if get_limit returns
-1/EINVAL, indicating that the kernel doesn't support that particular
limit
- add -i (max number of pending signals), -q (max size of posix msg
queues), -x (max number of file locks) for systems (Linux) that
support them
doc/{bash.1,bashref.texi}
- fix description of correspondence between FUNCNAME, BASH_LINENO,
and BASH_SOURCE indices in description of BASH_LINENO
9/18
----
lib/sh/shquote.c
- don't quote CTLESC and CTLNUL with CTLESC in sh_backslash_quote, as
long as the resultant string never gets sent to the word expansion
functions without going through the shell parser
externs.h
- add extern declarations for strnlen and strpbkrk from lib/sh
subst.[ch]
- changes to handle case where IFS consists of multibyte characters.
Changed: string_extract_verbatim, split_at_delims,
string_list_dollar_star, string_list_dollar_at, list_string,
get_word_from_string, setifs
9/19
----
mailcheck.c
- change file_mod_date_changed to reset the cached mail file data if
the file size drops to zero
lib/readline/complete.c
- change append_to_match so that a non-zero value for
rl_completion_suppress_append will cause no `/' to be appended to a
directory name
bashline.c
- experimental change to suppress appending a slash for a completed
filename that is found in PATH as well as a directory in the current
directory under certain circumstances: a single instance found in
$PATH when `.' is not in $PATH, and multiple instances found in the
$PATH, even when `.' is in the $PATH
9/24
----
command.h
- new word flag: W_ASSIGNRHS, means word is rhs of assignment statement
- new word flag: W_NOTILDE, means word is not to be tilde expanded
- new word flag (internal): W_ITILDE, means the next character is a
tilde that should be expanded
general.c
- new set of tilde suffixes for use when parsing the RHS of an
assignment statement and =~ should not be subject to tilde expansion
- if ASSIGN_P argument to bash_tilde_expand is 2, use tilde prefixes
for parsing RHS of assignment statement
general.[ch]
- new function bash_tilde_find_word, drop-in replacement for
tilde_find_word
subst.c
- call bash_tilde_expand with secord argument of 2 when expanding rhs
of an assignment statement, so tildes after second and subsequent
`=' in an assignment are not expanded
- new function, expand_string_assignment, to expand the rhs of an
assignment statement
- add `~' to EXP_CHAR, the characters that will cause the word
expansion functions to be called
- move tilde expansion into expand_word_internal instead of many
different calls to bash_tilde_expand scattered across different
functions. NOTE: This means that double quotes surrounding a
{paramOPword} expansion will cause tilde expansion to NOT be
performed on `word'. I think this is right, what POSIX specifies,
and consistent with the behavior of other characters in the rhs
execute_cmd.c
- take out calls to bash_tilde_expand before calling word expansion
functions
9/26
----
execute_cmd.c
- make sure to call UNBLOCK_CHILD before returning on a pipe creation
failure in execute_pipeline
9/27
----
variables.c
- change get_bash_command to deal with the_printed_command_except_trap
being NULL
execute_cmd.c
- fix execute_simple_command to deal with the_printed_command being
NULL when assigning to the_printed_command_except_trap -- fixes
seg fault in savestring()
parse.y
- change the parser so that the closing `)' in a compound variable
assignment delimits a token -- ksh93 does it this way
doc/{bash.1,bashref.texi}
- change description of tilde expansion to note that expansion is
attempted only after the first =~ in an assignment statement
builtins/declare.def
- when assigning to an array variable with declare -a x=(...), make
sure the last character in the rhs of the variable assignment is
`)', not just that it appears somewhere
9/28
----
command.h
- add a `W_NOEXPAND' flag to inhibit all expansion except quote removal
- add a `W_COMPASSIGN' flag to denote a word is a compound assignment
statement
parse.y
- set W_COMPASSIGN on words that appear to be compound assignments
subst.c
- pass W_NOXPAND and W_COMPASSIGN through end of expand_word_internal
subst.[ch]
- new function, expand_assignment_string_to_string, calls
expand_string_assignment and then string_list on the result
variables.c
- assign_in_env now calls expand_assignment_string_to_string
9/30
----
builtins/common.c
- change get_job_spec so the null job `%' once again means the current
job
10/1
----
subst.c
- do_assignment_internal now takes a WORD_DESC * as its first
argument, and uses its `word' member as the assignment string
- change expand_word_list_internal to call do_word_assignment instead
of do_assignment, passing it `word' instead of, e.g., `word->word'
- change extract_array_assignment_list to just return the passed
string minus a trailing `)' if the last character is a right
paren
- change do_assignment_internal to call extract_array_assignment_list
subst.[ch]
- change do_assignment and do_assignment_no_expand to take a `char *'
instead of `const char *' first argument; change extern prototypes
- new function, do_word_assignment, takes a WORD_DESC * and calls
do_assignment_internal on it; add extern declaration with prototype
general.h
- new typedef, sh_wassign_func_t, like sh_assign_func_t but takes a
WORD_DESC * as its first argument
variables.[ch]
- assign_in_env now takes a WORD_DESC * as its first argument
10/2
----
command.h
- new word flag, W_ASSNBLTIN, denotes that the word is a builtin
command (in a command position) that takes assignment statements
as arguments, like `declare'
- new word flags, W_ASSIGNARG, denotes that word is an assignment
statement given as argument to assignment builtin
execute_cmd.c
- set W_ASSNBLTIN flag in fix_assignment_words if necessary (if there
are any arguments that are assignment statements)
- set W_ASSIGNARG flag in fix_assignment_words if necessary
subst.c
- new function, do_compound_assignment, encapsulates the necessary
code to perform a compound array assignment (including creation of
local variables); called from do_assignment_internal
- to fix the double-expansion problem with compound array assignments
that are arguments to builtins like `declare', changed
shell_expand_word_list to treat those arguments like assignment
statements (with proper creation of local variables inside shell
functions) and pass the attribute-setting portion of the statement
onto the builtin. This is what ksh93 appears to do, from inspection
of the `ksh93 -x' output
execute_cmd.c
- fix execute_simple_command: in case of pipeline or async command,
when forking early, set `subshell_environment' so that it can contain
both SUBSHELL_PIPE and SUBSHELL_ASYNC -- the two should not be
mutually exclusive. Fixes bug reported by pierre.humblet@ieee.org
- remove references to last_pid, old_command_subst_pid; use NO_PID as
a sentinel value to decide whether or not a child process has been
created and needs to be waited for. Submitted by
pierre.humblet@ieee.org to fix recycling-pid problem on cygwin
doc/{bash.1,bashref.texi}
- fixed documentation of `@(pattern)' extended globbing operator --
it succeeds if the string matches one of the patterns, not exactly
one. This is what ksh93 does, too
lib/readline/complete.c
- fixed rl_menu_complete so that a negative argument cycles backwards
through the list
10/3
----
subst.c
- use W_COMPASSIGN flag in do_assignment_internal instead of deciding
lexically which assignments are compound array assignments
10/6
----
support/shobj-conf
- additions for System V.5 from Boyd Gerber <gerberb@zenez.com>
subst.c
- in command_substitute, if subshell_environment includes
SUBSHELL_ASYNC, call make_child with the `async_p' argument set to
non-zero. This keeps command substitutions for async commands or
pipelines from trying to give the terminal back to the shell's
pgrp. make sure to save and restore last_asynchronous_pid. Fix
suggested by <pierre.humblet@ieee.org>
10/7
----
config.h.in
- add a placeholder definition for WCONTINUED_BROKEN
10/9
----
aclocal.m4
- add BASH_CHECK_WCONTINUED, checks for glibc bug where WCONTINUED is
defined but rejected as invalid by waitpid(2)
configure.in
- add call to BASH_CHECK_WCONTINUED, defines WCONTINUED_BROKEN
redir.c
- experimental change to add_undo_redirect to save manipulations to
file descriptors >= SHELL_FD_BASE (10) on the list of redirections
to be undone even if `exec' causes the list to be discarded
doc/{bash.1,bashref.texi}
- note that redirections using file descriptors > 9 should be used
carefully, because they might conflict with file descriptors the
shell uses internally
10/11
-----
parse.y
- fix pipeline_command production to handle case where `pipeline'
as `argument' of `!' or `time' is null (e.g., a syntax error not
handled by the grammar)
10/13
-----
lib/readline/readline.c
- new internal variable, _rl_bind_stty_chars; if non-zero, bind the
terminal special characters to readline equivalents at startup
- change readline_default_bindings() and reset_default_bindings() to
understand _rl_bind_stty_chars
lib/readline/rlprivate.h
- new extern declaration for _rl_bind_stty_chars
lib/readline/rltty.c
- change rl_prep_terminal to add support for _rl_bind_stty_chars
10/15
-----
lib/readline/bind.c
- new bindable variable, `bind-tty-special-chars', bound to value of
_rl_bind_stty_chars
doc/bash.1,lib/readline/doc/{readline.3,rluser.texi}
- documented new readline variable `bind-tty-special-chars'
builtins/pushd.def
- make the first check for option `--' skip the rest of option
checking
10/16
-----
lib/readline/shell.c
- change sh_set_lines_and_columns to prefer setenv, which has
predictable memory allocation behavior, to putenv, which does not
10/19
-----
variables.c
- change push_exported_var so that a tempenv variable has to have the
export attribute set (which they all do -- something to look at) and
the `propagate' attribute set to be propagated down to the next
scope
execute_cmd.c
- change execute_builtin so that if CMD_COMMAND_BUILTIN is set in the
passed flags argument, call pop_scope with a value that says the
builtin is not special, since `command' means that preceding variable
assignments don't persist in the environment. Fixes problem with
variable assignments preceding command preceding special builtin
keeping those variable assignments around (when in posix mode)
10/20
-----
lib/sh/shquote.c
- new function, sh_mkdoublequoted, brackets a given string with
double quotes and returns a new string. Flags argument, if non-
zero, means to quote embedded double quotes with backslashes
externs.h
- new extern declaration for sh_mkdoublequoted
parse.y
- use sh_mkdoublequoted after calling localeexpand()
lib/sh/strtrans.c
- change ansicstr to understand that (flags & 4) != 0 means to remove
backslash from unrecognized escape sequences
general.c
- fix logic problem in assignment() that caused non-variable-starter
characters to be allowed, resulting in things like `1=xxx' creating
a variable `1' in the hash table
10/21
-----
bashline.c
- don't call programmable_completions with an assignment statement
argument
10/22
-----
lib/readline/rltty.c
- in prepare_terminal_settings, turn echoing on (readline_echoing_p)
if get_tty_settings fails because the input is not a terminal
10/24
-----
lib/readline/util.c
- include rlmbutil.h for multibyte definitions
- new function, _rl_walphabetic, wide char version of rl_alphabetic
lib/readline/mbutil.c
- new function, _rl_char_value(buf, ind), returns value of (possibly
multibyte) character at buf[ind]
lib/readline/rlmbutil.h
- extern defines for _rl_walphabetic and _rl_char_value for when
multibyte chars are not being used
- new wrapper definitions for _rl_find_next_mbchar (MB_NEXTCHAR) and
_rl_find_prev_mbchar (MB_PREVCHAR) that try to avoid unneeded
function calls
lib/readline/text.c
- fix rl_foward_word to work with multibyte characters (or in a
multibyte locale) using above utility functions
- fix rl_backward_word to work with multibyte characters (or in a
multibyte locale) using above utility functions
10/26
-----
parse.y
- fix parse_matched_pair so that it doesn't swallow \<newline> when
parsing a $'...' construct (call shell_getc with different arg)
10/28
-----
lib/glob/glob.c
- after some (compiled-in) threshold, glob_vector will stop using
alloca to allocate `struct globval's and will switch to using
malloc, with appropriate cleanup before returning
subst.c
- don't expand tildes after `=' in expand_word_internal, even if the
W_TILDEEXP flag is set, unless it's the first tilde in a word
marked W_ASSIGNMENT
10/31
-----
lib/readline/text.c
- make sure rl_point doesn't go below 0 in rl_delete_horizontal_space
(from SUSE, but not sent in)
shell.c
- make sure shell_is_restricted skips over a single leading `-' in
the shell name (from SUSE, but not sent in)
lib/readline/display.c
- disable `fast redisplay' at the end of the line if in a locale that
supports multibyte characters (from SUSE, but not sent in)
lib/readline/histexpand.c
- fix a problem with finding the delimiter of a `?' substring when
compiled for multibyte characters (from SUSE, but not sent in)
11/1
----
lib/readline/display.c
- correct some assignments to _rl_last_c_pos: when in a multibyte
locale, it's used as an absolute cursor position; when not using
multibyte characters, it's a buffer offset. I should have caught
this when the multibyte character support was donated
11/5
----
general.c
- change `assignment()' to accept `+=' assignment operator
arrayfunc.[ch]
- bind_array_variable and assign_array_element both take a new `flags'
argument
- assign_array_var_from_string, assign_array_from_string, and
assign_array_var_from_word_list now all take a new `flags' argument
- change assign_array_var_from_word_list to understand how to append
to an array variable
- change assign_array_var_from_string to understand how to append
to an array variable. It does not unset the previous value if
appending, allowing both old values to be changed and new ones to
be added
subst.h

arrayfunc.c
- break code that actually constructs the new value and assigns it
to a particular array index out into a new functions:
bind_array_var_internal. This fakes out make_variable_value by
passing a dummy SHELL_VAR * so it can do proper appending and other
+= processing
- changes to assign_array_var_from_string to accept and process as if
they were `standalone' assignment statements array assignment words
of the form [ind]+=val
11/7
----
builtins/declare.def
- added support for `declare [flags] var+=value'. `Flags' are applied
before the assignment is performed, which has implications for things
like `-i' -- if -i is supplied, arithmetic evaluation and increment
will be performed
builtins/setattr.def
- add support for `+=' assignment for rest of `assignment builtins':
export, readonly

trap.[ch]
- new function, int signal_in_progress(int sig), returns TRUE if the
trap handler for signal SIG is currently executing
11/19
-----
redir.c
- slightly change do_redirection_internal to set the close-on-exec
flag for file descriptors > 2 used to save file descriptors < 2
using explicit redirections (e.g., `exec 3>&1'). This keeps file
descriptors pointing to pipes from being left open but doesn't
change the shell's file descriptor semantics

doc/{bash.1,bashref.texi}
- correct some minor typos, forwarded from doko@debian.org
11/22
-----
doc/bash.1,lib/readline/doc/{readline.3,rluser.texi}
- documented detail that yank-last-arg and yank-nth-arg use the history
arg expansion code (and, as a result, are subject to restrictions
of the history-comment character)
11/23

execute_cmd.c
- changes so that BASH_COMMAND preserves its value into a DEBUG trap:
for commands, arithmetic for command expressions, select commands,
case commands, (( commands, [[ commands, simple commands
11/24
-----
doc/{bash.1,bashref.texi}
- changed description of `set' builtin slightly so that it is clear
that only variables are displayed in posix mode and that read-only
variables can't be reset by simply sourcing the output of `set'
lib/sh/strftime.c
- don't try to redefine `inline' if it's already defined
11/26

execute_cmd.c
- fix execute_function to check funcname_a after function execution,
since FUNCNAME can be changed or unset within a function
11/27
-----
builtins/evalfile.c
- make same changes as 11/26, this time to _evalfile
execute_cmd.c
- change execute_function to run the return trap after a function
completes execution even if the shell is compiled without DEBUGGER
defined
trap.c
- change reset_or_restore_signal_handlers so that the RETURN trap is
not inherited by command substitution when DEBUGGER is not defined
11/30
-----
lib/readline/misc.c
- fix memory leaks in _rl_free_history_entry and rl_maybe_replace_line
caused by not freeing `timestamp' member of history entry

execute_cmd.c
- fix execute_function so a function calling `return' will run the
RETURN trap, if one's defined
doc/{bash.1,bashref.texi}
- fix description of RETURN trap in various places to indicate that it's
only inherited by shell functions if function tracing is on globally
or has been enabled for that function
- fix documentation to indicate that the DEBUG and RETURN traps are
inherited under the same conditions
execute_cmd.c
- a function does not inherit the RETURN trap if a DEBUG trap is
currently running

builtins/set.def
- added description of `-' option to help text
builtins/shopt.def

READLINE is defined
12/16
-----
subst.c
- fixed a typo in string_extract_verbatim in first call to MBLEN
(used `slen - 1' instead of `slen - i')
12/17
-----
subst.c
- avoid some calls to strlen if the value is only being used for
ADVANCE_CHAR and MB_CUR_MAX == 1 (since ADVANCE_CHAR doesn't need
it unless multibyte characters are possible)
- change string_extract_verbatim so it takes the length of the string
as a parameter, so we don't have to recompute the length of the same
string over and over again when doing word splitting (that kills if
it's a long string)
12/18
-----
subst.c
- in string_list_dollar_star, make sure to null-terminate the
separator if the character is longer than one byte
12/22
-----
doc/{bash.1,bashref.texi}
- changed text in quoting section explaining that double quotes do
not prevent history expansion from taking place, and that backslashes
escaping ! are not removed
12/28
-----
shell.c
- set gnu_error_format to 1 if running under emacs. This should allow
the emacs `next-error' stuff to work, at least for interactive shells
parse.y
- change yy_stream_get to set interrupt_immediately before calling
getc_with_restart when the shell is interactive. This avoids the
synchronization problem caused by the call to QUIT in read_a_line,
which results in the first character after a SIGINT/^C to be
dropped
12/30
-----
builtins/mkbuiltins.c
- changes to write long documentation to arrays as a single string by
default, rather than an array of strings -- enabled by default
- new option, -S, to restore old behavior of writing multiple strings
for long documentation
- changes to avoid filenames written when the separate-filenames option
(-H) has been supplied being run through gettext
configure.in
- new cofiguration option, --enable-single-help-strings (on by default),
causes help text to be stored as a single string (or smaller set than
one string per line)
builtins/Makefile.in
- pass `-S' to mkbuiltins if single-help-strings is turned off
doc/bashref.texi
- documented new `single-help-strings' configure option
1/3/2005
--------
jobs.c
- make wait_for return a non-zero status if the job or processed
waited for is suspended. Returns 128 + stop signal. This fixes
the problem with `echo one && sleep 5 && echo two' displaying
`two' after the sleep is suspended
1/5
---
print_cmd.c
- change indirection_level_string so the code duplicates the first
character of $PS4 to indicate the indirection level, rather than
the first byte
1/8
---
variables.c
- new special variable hook function for COMP_WORDBREAKS; sets
rl_completer_word_break_characters back to NULL when the variable
is unset
- change bind_variable_value to understand dynamic variables with
assign_function set, and handle them correctly. If the variable is
being appended to, use make_variable_value to create the new
value
- change bind_variable_internal to understand dynamic variables with
assign_function set, and handle them the same way
- RANDOM and LINENO now get the integer attribute, so appending works
as expected
- ditto for HISTCMD, MAILCHECK, OPTIND
lib/readline/display.c
- change _rl_make_prompt_for_search to set prompt_physical_chars
appropriately
- rl_save_prompt and rl_restore_prompt save and restore
prompt_prefix_length
- change redraw_prompt to use rl_save_prompt and rl_restore_prompt
- change rl_restore_prompt to set the `save' variables back to
NULL/0 so code can check whether or not the prompt has been saved
- change rl_message and rl_clear_message to save and restore the
prompt if the caller has not already done it (using a simple
semaphore-like variable)
- change rl_message to call expand_prompt, so that local_prompt and
local_prompt prefix are set before calling the redisplay functions,
in case the prompt is longer than a screenwidth (fixes bug
reported to debian by epl@unimelb.edu.au)
lib/readline/doc/rltech.texi
- make sure to note that rl_save_prompt should be called before
rl_message, and rl_restore_prompt before rl_clear_message
pcomplete.c
- make sure to save and restore the parser state around the call to
execute_shell_function in gen_shell_function_matches. Fixes bug
reported by a050106.1.keeLae3x@captaincrumb.com (cute)
lib/readline/readline.c
- fix _rl_dispatch_subseq in the case where we're recursing back up
the chain (r == -2) and we encounter a key shadowed by a keymap,
but originally bound to self-insert. Calling rl_dispatch with
ANYOTHERKEY as the first argument will call rl_insert, but with
ANYOTHERKEY (256) as the char to insert. Use the shadow keymap
and set things up to dispatch to rl_insert with the shadowed key
as the argument. Fixes the bug reported by Thomas Glanzmann

dispose_cmd.c
- new function to just free a WORD_DESC * without freeing the contained

subst.c
- param_expand now returns a WORD_DESC * -- changed callers to
understand
- parameter_brace_expand now returns a WORD_DESC * -- changed
callers to understand
- in expand_word_internal, only call remove_quoted_nulls after a word
is returned with W_HASQUOTEDNULL
- changes to pass W_HASQUOTEDNULL flag out of expand_word_internal;
changed callers to call remove_quoted_nulls only if return value has
W_HASQUOTEDNULL set. This is a mostly-complete fix for the
long-standing CTLNUL confusion between a quoted null expansion and
the expansion of a variable with a literal '\177' in its value
- change string_list_dollar_at to compute the separator character the
same way as string_list_dollar_star: using the already-computed
values generated in setifs()
- when expanding unquoted $*, if $IFS is empty, check whether or not
we're eventually going to split the results (e.g., on the rhs of an
assignment statement) and concatenate the positional parameters as
if the expansion were within double quotes if we're not going to
split
tests/iquote.tests
- test cases based on old bug reports about the quoted-null vs. 0177
problem the recent code fixes

dispose_cmd.c
- set w->word to 0 before putting a WORD_DESC * back in the cache in
dispose_word_desc; changed callers to delete those assignments
variables.c
- change assign_random and get_random_value so that the random number
generator only gets re-seeded once in a subshell environment, and
assigning a value to RANDOM counts as seeding the generator. This
makes the sequences a little more predictable

configure.in
- set BUILD_DIR to contain backslashes to escape any spaces in the
directory name -- this is what make will accept in targets and
prerequisites, so it's better than trying to use double quotes
- set SIZE to the appropriate value if some cross-compiling tool
chain is being used; `size' by default (can be overridden by
SIZE environment variable)
Makefile.in
- use $(SIZE) instead of size; set SIZE from configure

- change some uses of global and static variables to use members of
new struct (struct jobstats)

jobs.[ch]
- change PRUNNING to PALIVE
- new define INVALID_JOB
- new macro get_job_by_jid(ind), currently expands to jobs[ind]
- new define J_JOBSTATE, operates on a JOB * like JOBSTATE operates on
a job index
- new function, reset_job_indices, called from delete_job if
js.j_lastj or js.j_firstj are removed
- change various functions to keep counters and stats in struct jobstats
pcomplete.c, builtins/common.c, builtins/{exit,fg_bg,jobs,kill,wait}.def
- change global variables (e.g., job_slots) to struct members
(e.g., js.j_jobslots)
- use INVALID_JOB define where appropriate
- use get_job_by_jid and J_JOBSTATE where appropriate
trap.c
- change reset_or_restore_signal_handler to not free the exit trap
string if the function pointer is reset_signal, which is used when
the trap strings shouldn't be freed, like in command substitution
2/4

jobs.c
- new function, realloc_jobs_list, copies jobs array to newly-allocated
memory shrinking (or growing) size to have next multiple of JOB_SLOTS
greater than js.j_njobs
- change compact_jobs_list to just call reap_dead_jobs and then
realloc_jobs_list, simplifying it considerably
- discard_pipeline now returns `int': the number of processes freed
- slightly changed the logic deciding whether or not to call
compact_jobs_list: now non-interactive shells will compact the
list if it reaches MAX_JOBS_IN_ARRAY in size
parse.y
- move test for backslash-newline after pop_string in shell_getc so
that things like
((echo 5) \

jobs.h
- new structs for holding status of exited background processes, as
POSIX specifies
- new job flag: J_ASYNC
jobs.c
- new functions to manipulate struct holding status of exited
background processes
- new members in struct jobstats to hold pointer to last created job
and last created asynchronous job
- initialize js.c_childmax in initialize_job_control
- if the `async' arg to stop_pipeline is non-null, set the J_ASYNC
flag in the job struct
- set js.j_last_made_job and js.j_last_asynchronous_job in
stop_pipeline
- new function: find_last_proc, returns the PROCESS * to the last proc
in a job's pipeline
- changed find_last_pid to call find_last_proc

deleted
- change delete_all_jobs and wait_for_background_pids to call bgp_clear

jobs.h
- add support for PS_RECYCLED as a process state, add PRECYCLED macro
to test it. Change PALIVE and PRUNNING macros to not count processes
in PS_RECYCLED state
execute_cmd.c
- restore use of last_pid as sentinel value; use NO_PID as sentinel
only if RECYCLES_PIDS is defined
jobs.c
- change find_job to return a pointer to the PROCESS the desired pid
belongs to, analogous to find_pipeline returning pointer to JOB
- change find_job callers to add extra argument
- change running_only arguments to find_pipeline and find_job to
alive_only, since we don't want recycled pids returned here and it
better describes the result
- new function find_process, calls find_pipeline and searches the
returned pipeline for the PROCESS * describing the desired pid
- in make_child, if fork() returns the same pid as the value of
last_asynchronous_pid when RECYCLES_PIDS is defined, avoid pid
aliasing by resetting last_asynchronous_pid to 1
- use PRUNNING instead of child->running, since we, for the most
part, don't want to consider recycled pids (e.g., in make_child())
- call find_process instead of find_pipeline in waitchld()
- use PEXITED(p) instead of testing p->running == PS_DONE
- in make_child, call bgp_delete to remove a just-created pid from the
last of saved pid statuses
- in add_process, check whether or not pid being added is already in
the_pipeline or the jobs list (using find_process) and mark it as
recycled if so
- This set of fixes mostly came from Pierre Humblet
<pierre.humblet@ieee.org> to fix pid aliasing and reuse problems on
cygwin
variables.c

subst.c
- change list_string and get_word_from_string to explicitly treat an
IFS character that is not space, tab, or newline *and any adjacent
IFS white space* as a single delimiter, as SUSv3/XPG6 says
builtins/read.def
- check whether or not the number of fields is exactly the same as
the number of variables instead of just assigning the rest of the
line (minus any trailing IFS white space) to the last variable.
This parses a field and checks whether or not it consumes all of
the input (including any trailing field delimiters), falling back
to the previous behavior if it does not. This is what POSIX.2
specifies, I believe (and the consensus of the austin-group list).
This requires a few tests in read.tests to be changed: backslashes
escaping IFS whitespace characters at the end of input cause the
whitespace characters to be preserved in the value assigned to the
variable, and the trailing non-whitespace field delimiter issue

Preparation for printf -v var
- add code to add the text printed to a `variable buffer' if -v option
supplied. The buffer grows as needed
- printf now takes a `-v var' option to put the output into the variable
VAR rather than sending it to stdout. It does not:
print partial output on error (e.g., format string error)
handle NULs in the variable value, as usual

the format passed to sprintf()
- fix STAR_ARGS macro to deal with negative field widths and precisions
3/25
----
builtins/printf.def
- since a negative precision in a "x.x[fFgGeE]" format specifier should
be allowed but treated as if the precision were missing, let it
through
lib/sh/snprintf.c

the `.' and any digit string in the precision had not been specified
- fix format parsing code to deal with a negative inline precision,
e.g., "%4.-4f" by treating it as if the `'. and any digit string in
the precision had not been specified
- a `+' in a format specifier should only act as a flag if it comes
before a `.' (otherwise it is ignored)
lib/readline/vi_mode.c

lib/readline/rlprivate.h
- definition of a readline `search context', to be use for incremental
search initially and other types of search later. Original from
Bob Rossi as part of work on incremental searching problems when
using callback interface
lib/readline/isearch.c
- functions to allocate and free search contexts
- function to take a search context and a character just read and
`dispatch' on it: change search parameters, add to search string,
search further, etc.
- isearch is now completely context-driven: a search context is
allocated and passed to the rest of the functions
5/12
----
lib/readline/isearch.c
- an additional `isearch cleanup' function that can be called from
the callback interface functions when the search is to be terminated
- an additional `isearch callback' function that can be called from
rl_callback_read_char when input is available
- short-circuit from rl_search_history after initialization if
the callback interface is being used
lib/readline/callback.c
- in rl_callback_read_char(), if RL_STATE_ISEARCH is set, call
_rl_isearch_callback to read the character and dispatch on it.
If RL_STATE_ISEARCH is unset when that call returns, and there is
input pending, call rl_callback_read_char() again so we don't
have to wait for new input to pick it up
support/shobj-conf,configure.in
- add support for dragonfly bsd, the same as freebsd
5/13-5/15
---------
lib/readline/callback.c
- support for readline functions to `register' a function that will
be called when more input is available, with a generic data
structure to encapsulate the arguments and parameters. Primarily
intended for functions that read a single additional character,
like quoted-insert
- support for callback code reading numeric arguments in a loop,
using readline state and an auxiliary variable
- support for callback code performing non-incremental searches using
the same search context struct as the isearch code
lib/readline/{callback,display}.c
- if a callback function sets `_rl_redisplay_wanted', the redisplay
function will be called as soon as it returns
lib/readline/input.c
- changes to _rl_read_mbchar to handle reading the null multibyte
character and translating it into '\0'
lib/readline/misc.c
- break rl_digit_loop() into component functions that can be called
individually from the callback code more easily
- share some of the functions with rl_digit_loop1() in vi_mode.c
lib/readline/readline.h
- change the version #defines to reflect readline 5.1
lib/readline/search.c
- break code into smaller functions that can be composed to work with
the callback code more easily
lib/readline/text.c
- in rl_quoted_insert(), don't mess around with the tty signals if
running in `callback mode'
lib/readline/vi_mode.c
- changed set-mark, goto-mark, change-char, and char-search to work
when called by callback functions

lib/readline/rlprivate.h
- new struct declaration for a `reading key sequence' context
lib/readline/readline.c

lib/readline/rlprivate.h
- new struct defining a context for multiple-key key sequences (the
base case is escape-prefixed commands)
lib/readline/readline.c
- change structure of _rl_dispatch_subseq to allow for callback code
to use it - rudimentary support for supporting the existing
recursion using a stack of contexts, each with a reference to the
previous
- fix so that ^G works when in callback mode
lib/readline/callback.c
- call the appropriate multiple-key sequence callback if the state is
set
5/19
----
lib/readline/readline.c
- broke code from _readline_internal_char after call to rl_dispatch
out into separate function: _rl_internal_char_cleanup, callable by
other parts of the code
- change _rl_internal_char_cleanup to unset _rl_want_redisplay after
it calls (*rl_redisplay_func)
lib/readline/callback.c
- call _rl_internal_char_cleanup from rl_callback_read_char when
appropriate
5/24
----
lib/readline/callback.c
- use _rl_dispatch_callback and a chain of _rl_keyseq_contexts to
simulate the recursion used to decode multicharacter key sequences
(even things like ESC- as meta-prefix)
- call setjmp in rl_callback_read_char to give things like rl_abort
a place to jump, since the saved location in readline() will not
be valid
- keep calling _rl_dispatch_callback from rl_callback_read_char while
we are still decoding a multi-key key sequence
- keep calling readline_internal_char from rl_callback_read_char while
we are reading characters from a macro
lib/readline/macro.c
- use a slightly different strategy upon encountering the end of a macro
when using the callback interface: when the last character of a
macro is read, and we are reading a command, pop the macro off the
stack immediately so the loop in rl_callback_read_char terminates
when it should
lib/readline/readline.c
- if longjmp() is called and we end up at the saved location while
using the callback interface, just return -- don't go back into a
blocking read
- new function to dispose a chain of rl_keyseq_cxts
- only read new input in _rl_dispatch_callback if the KSEQ_DISPATCHED
flag is not set in the current keyseq context -- if it is, we are
traversing the chain back up and should use what we already saved
- use -3 as a magic value from _rl_dispatch_subseq to indicate that
we're allocating a new context and moving downward in the chain
(a special return value for the benefit of _rl_dispatch_callback)
lib/readline/rlprivate.h
- new extern declaration for _rl_keyseq_chain_dispose
6/1

builtins/read.def
- fixed a bug that occurred when reading a set number of chars and
the nth char is a backslash (read one too many). Bug reported by
Chris Morgan <chmorgan@gmail.com>
execute_cmd.c
- fix execute_builtin so the `unset' builtin also operates on the
temporary environment in POSIX mode (as well as source and eval),
so that unsetting variables in the temporary environment doesn't
leave them set when unset completes. Report by Eric Blake
<ebb9@byu.net>
array.c
- fix from William Park for array_rshift when shifting right on an
empty array -- corrects calculation of array->max_index
builtins/exec.def

add a backslash in front of a newline in sh_double_quote. Problem
reported by William Park
jobs.c

terminated background processes unless job control is active
bashhist.c
- new variable, hist_last_line_pushed, set to 0 in really_add_history
(used by `history -s' code)
bashhist.h
- new extern declaration for history -s
builtins/history.def
- don't remove last history entry in push_history if it was added by
a call to push_history -- use hist_last_line_pushed as a sentinel
and set it after adding history entry. This allows multiple
calls to history -s to work right: adding all lines to the history
rather than deleting all but the last. Bug reported by Matthias
Schniedermeyer <ms@citd.de>

findcmd.c
- rewrote file_status to use S_xxx POSIX file mode bits and to add
support for FS_READABLE (affects ./source and searching $PATH for

lib/readline/isearch.c
- when switching directions, make sure we turn off the SF_REVERSE
flag in the search context's flags word if we're going from reverse
to forward i-search
lib/readline/bind.c
- new function, rl_variable_value, returns a string representing a
bindable readline variable's value
- new auxiliary function, _rl_get_string_variable_value, encapsulates
everything needed to get a bindable string variable's value
- rewrote rl_variable_dumper to use _rl_get_string_variable_value
lib/readline/readline.h
- new extern declaration for rl_variable_value
lib/readline/doc/rltech.texi
- documented rl_variable_value
bashline.c
- in command_word_completion_function, if readline sets
rl_completion_found_quote, but doesn't set rl_completion_quote_character,
we have an embedded quoted string or backslash-escaped character in
the passed text. We need to dequote that before calling
filename_completion_function. So far, this is in place only for
absolute program names (those containing a `/')
- in command_word_completion_function, use rl_variable_value to decide
whether or not we should ignore case, and use strncasecmp instead of
strncmp where appropriate

flag when making new redirects
- in do_redirection_internal, only set file descriptors > 2 to CLEXEC
if they're marked as RX_INTERNAL

lib/readline/undo.c
- in rl_revert_line, make sure that revert-line in vi mode leaves
rl_point set to 0 no matter the state of the line buffer
lib/readline/vi_mode.c
- when entering vi_command mode for the first time, free any existing
undo list so the previous insertions won't be undone by the `U'
command. This is how POSIX.2 says `U' should work (and the test
suite tests for it)
lib/readline/bind.c

{jobs,nojobs,sig}.c,{jobs,sig}.h
- moved SIGWINCH handling code to sig.c rather than duplicate it in
jobs.c and nojobs.c
- call set_sigwinch_handler from sig.c code rather than job control
signal initialization
sig.[ch]
- new variable, sigwinch_received, acts like interrupt_state for
SIGWINCH, set by sigwinch_sighandler. sigwinch_sighandler no longer
calls get_new_window_size

reset readline's idea of the terminal size
- don't call _rl_get_screen_size in _rl_init_terminal_io if both
_rl_screenheight and _rl_screenwidth are > 0
- don't initialize _rl_screenheight and _rl_screenwidth to 0 in
_rl_init_terminal_io; let caller take care of it
- set _rl_screenheight and _rl_screenwidth to 0 before calling
_rl_init_terminal_io
lib/readline/readline.h
- new extern declaration for rl_reset_screen_size
lib/readline/doc/rltech.texi
- documented rl_reset_screen_size
variables.c
- if readline is being used, compile in a special var function for
assignments to LINES and COLUMNS that calls rl_set_screen_size or
rl_reset_screen_size as appropriate. Only do this in posix mode
and only when STRICT_POSIX is defined at compile time
- new semaphore variable, winsize_assignment, set while doing an
assignment to LINES or COLUMNS
- new variable, winsize_assigned, says LINES or COLUMNS was assigned
to or found in the environment
- if in the middle of an assignment to LINES or COLUMNS, make
sh_set_lines_and_columns a no-op
lib/sh/winsize.c

_rl_last_c_pos without taking invisible characters in the line into
account. Important in multibyte locales where _rl_last_c_pos is an
absolute cursor position
- changes to _rl_move_cursor_relative to account for _rl_last_c_pos
being an absolute cursor position in a multibyte character locale
- rewrote _rl_move_cursor_relative to make it a little simpler
11/29
-----
lib/readline/display.c
- changes to rl_redisplay and update_line for update_line to communicate
upward that it took the number of invisible characters on the current
line into account when modifying _rl_last_c_pos
- in update_line, adjust _rl_last_c_pos by wrap_offset before calling
_rl_move_cursor_relative, so we pass correct information about the

lib/readline/readline.c
- don't return the value of the called readline function as the return

-----
lib/readline/display.c
- don't treat RL_PROMPT_START_IGNORE specially inside a sequence of

- keep track of the start of the current sequence of ignored
characters; make sure that an empty sequence of such characters
really is an empty sequence, not one that happens to end with '\001'

subst.c
- change expand_word_internal to process rest of `tilde-word' as a
regular part of the word if tilde expansion leaves the tilde-word
unchanged. This means that ~$USER expands to ~chet, which seems
more intuitive, and is effectively what bash-3.0 did
12/23
-----
subst.c
- when making a local array variable in do_compound_assignment, make
sure that we don't use a variable of the same name from a previous
context
doc/bash.1

execute_cmd.c
- in execute_arith_command, if the expression expands to more than one
word, make sure we join the words into a single string and pass the
entire thing to evalexp()
expr.c
- new functions: _is_arithop(c), returns true if C is a valid single-
character arithmetic operator; _is_multiop(c), returns true if C is
a token corresponding to a valid multi-character arithmetic operator
- if we encounter a character that isn't a valid arithmetic
operator, throw an error. Try to be intelligent about what type of
error message to print
subst.c
- new function, expand_arith_string, calls expand_string_if_necessary;
used where an arithmetic expression needs to be expanded
subst.h
- new extern declaration for expand_arith_string
arrayfunc.c
- in array_expand_index, call expand_arith_string to expand the
subscript in a fashion consistent with other arithmetic expressions
subst.c
- fix parameter_brace_patsub so that we don't try to anchor the pattern
at the beginning or end of the string if we're doing global
replacement -- that combination doesn't doesn't make sense, and
the changed behavior is compatible with ksh93
doc/{bash.1,bashref.texi}
- changed description of pattern substitution to match the new

support/signames.c
- new file, initialize_signames() function from old mksignames.c. This
file builds the signal_names array
support/mksignames.c
- strip out initialize_signames(), move to signames.c. This file only
writes signames.h
- set up to only write a stub signames.h if CROSS_COMPILING is defined,
with extern declaration for initialize_signames
- if not cross compiling, #define initialize_signames to nothing
Makefile.in
- mksignames is now linked from mksignames.o and buildsignames.o
- add rules to build signames.o, assuming we're building it as part
of the shell (cross-compiling)
trap.c
- call initialize_signames from initialize_traps
configure.in
- set SIGNAMES_O to nothing (normal) or signames.o (cross-compiling),
substitute into Makefile
- don't set SIGNAMES_H if cross-compiling any more
12/30

command.h
- new word flag: W_NOPROCSUB, inhibits process substitution on a word
subst.c
- change expand_word_internal to suppress process substitution if the
word has the W_NOPROCSUB flag
shell.c
- --wordexp turns on W_NOPROCSUB in addition to W_NOCOMSUB
subst.c
- change string_list_dollar_at and string_list_dollar_star so that
MB_CUR_MAX is used to size an array only when using gcc, since gcc
can handle non-constant array sizes using a mechanism like alloca.
Other compilers, e.g. Sun's compiler, do not implement that
extension
12/31

builtins/mkbuiltins.c
- when cross-compiling, don't include <config.h>, since it's for the
target rather than the host system. Instead, choose a reasonable
set of default #defines based on a minimal POSIX system
jobs.c
- change find_process to handle a NULL return value from find_pipeline

- don't allocate a new list in realloc_jobs_list if the old size and
new size are the same; just compact the existing list
- make sure realloc_jobs_list updates value of js.j_njobs

lib/readline/vi_mode.c
- move code that moves forward a character out of rl_vi_append_mode
into a separate function, _rl_vi_append_forward
- change _rl_vi_append_mode to save `a' as the last command, so it
can be redone properly
- new function _rl_vi_backup, moves point back a character taking
multibyte locales into account
- change rl_vi_redo to handle redoing an `a' command specially --
it should be redone like `i' but after moving forward a character
- change rl_vi_redo to use _rl_vi_backup to move point backward
after redoing `i' or `a'
jobs.c
- new function, delete_old_job (pid), checks whether or not PID is in
a job in the jobs list. If so, and the job is dead, it just removes
the job from the list. If so, and the job is not dead, it zeros
the pid in the appropriate PROCESS so pid aliasing doesn't occur
- make_child calls delete_old_job to potentially remove an already-used
instance of the pid just forked from the jobs list if pids have
wrapped around. Finally fixes the bug reported by Tim Waugh
<twaugh@redhat.com>
trap.c
- new define, GETORIGSIG(sig), gets the original handling for SIG and
sets SIG_HARD_IGNORE if that handler is SIG_IGN
- call GETORIGSIG from initialize_traps, get_original_signal, and
set_signal
jobs.c
- in wait_for, if the original SIGINT handler is SIG_IGN, don't set
the handler to wait_sigint_handler. This keeps scripts started in
the background (and ignoring SIGINT) from dying due to SIGINT while
they're waiting for a child to exit. Bug reported by Ingemar
Nilsson <init@kth.se>
lib/readline/vi_mode.c
- don't save text to buffer unless undo pointer points to a record of
type UNDO_INSERT; zero it out instead. This fixes bug reported by
Craig Turner <craig@synect.com> with redoing `ctd[ESC]' (empty
insert after change to)
shell.c
- change set_shell_name so invocations like "-/bin/bash" are marked as
login shells
doc/bash.1
- add note about destroying functions with `unset -f' to the section
on shell functions
lib/readline/terminal.c
- if readline hasn't been initialized (_rl_term_autowrap == -1, the
value it's now initialized with), call _rl_init_terminal_io from
_rl_set_screen_size before deciding whether or not to decrement
_rl_screenwidth. Fixes bug from Mike Frysinger <vapier@gentoo.org>

lib/readline/input.c
- allow rl_set_keyboard_input_timeout to set the timeout to 0, for
applications that want to use select() like a poll without any
waiting
lib/readline/doc/rltech.texi
- documented valid values for timeout in rl_set_keyboard_input_timeout
jobs.c
- in stop_pipeline, don't have the parent shell call give_terminal_to
if subshell_environment contains SUBSHELL_ASYNC (no background
process should ever give the terminal to anything other than
shell_pgrp)
- in make_child, don't give the terminal away if subshell_environment
contains SUBSHELL_ASYNC

convert-meta when listing key bindings, since if convert-meta is off,
using '\M-' as the prefix for bindings in, for instance,
emacs-escape-keymap, is wrong. This affects `bind -p' output
- change rl_untranslate_keyseq to add '\e' instead of '\C-[' for
ESC
execute_cmd.c
- add call to QUIT at end of execute_command
1/23
----
lib/readline/display.c
- changed two places in update_line where a check of whether the cursor
is before the last invisible character in the prompt string to
differentiate between the multibyte character case (where
_rl_last_c_pos is a physical cursor position) and the single-byte
case (where it is a buffer index). This prevents many unnecessary
\r-redraw the line sequences. Reported by Dan Jacobson.

parse.y
- undo change that makes `)' in a compound assignment delimit a token.
It messes up arithmetic expressions in assignments to `let', among

sig.h,{jobs,nojobs,sig,trap}.c,builtins/trap.def
- rename termination_unwind_protect to termsig_sighandler
sig.c
- split termsig_sighandler into two functions: termsig_sighandler, which
runs as a signal handler and sets a flag noting that a terminating
signal was received, and termsig_handler, which runs when it is `safe'
to handle the signal and exit
- new terminate_immediately variable, similar to interrupt_immediately
- termsig_sighandler calls termsig_handler immediately if
terminate_immediately is non-zero
quit.h
- change CHECK_TERMSIG macro to check terminating_signal and call
termsig_handler if it's non-zero
- add same check of terminating_signal and call to termsig_handler to
QUIT macro
{jobs,nojobs}.c
- change call to termsig_sighandler to call termsig_handler directly,

name before calling the directory-completion-hook. Bug reported by
Andrew Parker <andrewparker@bigfoot.com>
bashline.c

needs to dequote the directory name even if no other expansions are

----
braces.c
- make sure that we skip over braces that don't start a valid matched
brace expansion construct in brace_expand -- there might be a valid
brace expansion after the unmatched `{' later in the string
- brace_gobbler now checks that when looking for a `}' to end a brace
expansion word, there is an unquoted `,' or `..' that's not inside
another pair of braces. Fixes the a{b{c,d}e}f problem reported by
Tim Waugh
builtins/declare.def
- when not in posix mode, and operating on shell functions, typeset

shell identifiers. The other `attribute' builtins work this way.
Fixes inconsistency reported by Mike Frysinger <vapier@gentoo.org>
{configure,config.h}.in
- add test for setregid, define HAVE_SETREGID and HAVE_DECL_SETREGID
as appropriate
- add test for eaccess, define HAVE_EACCESS if found
lib/sh/eaccess.c
- new file, with sh_stat and sh_eaccess functions, moved from test.c
- renamed old sh_eaccess as sh_stataccess, since it uses the stat(2)
information to determine file accessibility
- new function, sh_euidaccess, to call when uid != euid or gid != egid;
temporarily swaps uid/euid and gid/egid around call to access
- rewrote sh_eaccess to call eaccess, access, sh_euidaccess or
sh_stataccess as appropriate. access(2) will take into account

lib/readline/display.c
- make sure that _rl_col_width is never called with MB_CUR_MAX == 1,

compensated for. Added a warning in _rl_col_width if called when
MB_CUR_MAX == 1. Bug reported and solution suggested by Eric
Blake <ebb9@byu.net>

lib/readline/display.c
- make sure _rl_wrapped_line is initialized to inv_lbsize int chars.
inv_lbsize and vis_lbsize are the same at that point, but it makes
the intent clearer. Fix from jan.kratochvil@redhat.com.
- in rl_redisplay, make sure we call memset on _rl_wrapped_line with
its full initialized size: inv_lbsize*sizeof(int). Fix from
jan.kratochvil@redhat.com.
- wrap the invisible and visible line variables and _rl_wrapped_line
into line_state structures, which can be swapped more efficiently.
Have to watch the wrapped_line field, since there's now one for
each struct. Changes from jan.kratochvil@redhat.com.
lib/readline/complete.c
- in stat_char, check for `//server' on cygwin and return `/', since
it will always behave as a directory. Fix from Eric Blake
lib/readline/histfile.c

- change display_signal_list (used by `trap -l' and `kill -l') to use
five columns instead of 4 to display signal names
builtins/help.def
- use the true terminal width instead of assuming 80 when displaying
help topics, leaving two characters of whitespace between horizontal

execute_cmd.c
- in execute_simple_command, if the first word of a simple command is
a directory name (after looking for builtins, so `.' isn't caught)
that isn't found in $PATH, and `autocd' is non-zero, prefix a "cd"
to the command words

- add ` (backquote) to the list of vi motion characters
- in rl_vi_delete_to, rl_vi_change_to, and rl_vi_yank_to, don't delete
character under the cursor if the motion command moves the cursor
backward, so add F and T to the commands that don't cause the
mark to be adjusted
- add ` to the characters that don't cause the mark to be adjusted
when used as a motion command, since it's defined to behave that way
- when a motion character that may adjust the mark moves point
backward, don't adjust the mark so the character under the cursor
isn't deleted
lib/readline/complete.c
- add variable rl_sort_completion_matches; allows application to
inhibit match list sorting

- make sure that the first character following the history comment
character at the beginning of a line is a digit before interpreting
it as a timestamp for the previous line
doc/{bash.1,bashref.texi},lib/readline/doc/hsuser.texi
- added detail to make it clear exactly how history timestamps are

subst.c
- change quote_escapes to add CTLESC before spaces if IFS is null,
just in case we have to split on literal spaces later on (e.g., in

on each element of the array in the same way array_quote calls
quote_string
- call array_quote_escapes if match is not quoted in array_patsub
- array_slice is now used, so remove the #ifdef INCLUDE_UNUSED define
- change structure of array_subrange to call array_slice to create a
new array with the desired subset of elements, then call array_quote
or array_quote_escapes as necessary, like array_patsub. Convert to
a string by calling array_to_string on the sliced-out array
array.h
- new extern declaration for array_quote_escapes
subst.c
- since array_patsub now calls quote_escapes as necessary, callers
don't need to call it after array_patsub returns. Fixes first bug
reported by Brett Stahlman <brettstahlman@comcast.net>
- since array_subrange now calls quote_escapes as necessary, callers
don't need to call it after array_patsub returns. Same fix as
for array_patsub

configure.in
- add -DSOLARIS to LOCAL_CFLAGS for solaris x
config-bot.h
- don't #undef HAVE_GETCWD if GETCWD_BROKEN and SOLARIS are both
defined. Solaris's loopback mount implementation breaks some of the
file system assumptions the replacement getcwd uses.
builtins/common.c
- if GETCWD_BROKEN is defined, call getcwd with PATH_MAX for the size
argument, so it will allocate a buffer for the current working dir
with that size, instead of one that's `big enough'
config.h.in
- add #undef PRI_MACROS_BROKEN for AIX 4.3.3
pathexp.h
- new flag value for quote_string_for_globbing: QGLOB_REGEXP (quoting
an ERE for matching as a string)
pathexp.c
- change quote_string_for_globbing to understand QGLOB_REGEXP
execute_cmd.c
- change execute_cond_node to pass 2 (regexp match), 1 (shell pattern
match), or 0 (no matching) to cond_expand_word
subst.c
- change cond_expand_word to translate SPECIAL==2 into passing
QGLOB_REGEXP to quote_string_for_globbing
locale.c

cleanup needs to be performed before a non-fatal call to
jump_to_top_level
sig.h

builtins/common.c
- add calls to top_level_cleanup before calls to jump_to_top_level
in a builtin command context (no_args(), get_numeric_arg()). Fixes
bug reported by Ian Watson
lib/readline/display.c
- in _rl_move_cursor_relative, use `new' when comparing against
the last invisible character in the prompt, since they both denote
buffer indices when in a multibyte locale, whereas `dpos' is a
display position

if the file size is less than SSIZE_MAX. These fix problems
reported by hooanon05@yahoo.co.jp.
include/typemax.h
- define SSIZE_MAX as 32767 if it's not defined
lib/readline/display.c
- in rl_redisplay() and update_line(), if redrawing the prompt because
it contains invisible characters, make sure we redraw the character
indicating a modified history line and take it into account when
computing _rl_last_c_pos
- in update_line, if deleting characters and redrawing the new text,
make sure we adjust _rl_last_c_pos by wrap_offset in a multibyte
locale if the text we're drawing starts before or at the last
invisible character in the prompt string. Fixes bug reported on
bug-readline by J Pelkey <pelkeyj@gmail.com>

- new flag, SX_NOCTLESC, obeyed by string_extract_verbatim, tells it
to not obey CTLESC quoting
- change quote_escapes to not quote CTLESC with CTLESC if one of the
chars in $IFS is CTLESC, since the return value from quote_string
will be passed to word splitting and filename generation
- change read_comsub to do the same thing for unquoted command
substitutions
- change list_string to pass SX_NOCTLESC if CTLESC is one of the
chars in $IFS, so it will split on CTLESC instead of using it as a
quote character
4/7

subst.c
- slight change to string_extract_verbatim to allow CTLESC to quote

- change add_undo_redirect to differentiate between file descriptors
greater than SHELL_FD_BASE (currently 10) used internally to save
others and then being the targets of user redirection and fds that
are just the target of user redirections. The former need to have
an `exec undo' redirect added to undo it in case exec throws away
redirections; the latter does not. We use the close-on-exec flag
for this: if it's set, we assume that the file descriptor is being
used internally to save another. Fixes problem reported by Ian
Jackson <ian@davenant.greenend.org.uk>
shell.c
- new function, init_interactive_script(), does interactive initialization
for a script run with `bash -i script' -- does everything the same
as init_interactive except set `interactive == 1', which causes the
shell to read from the standard input, after calling
init_noninteractive
- call init_interactive_script if a script is run as `bash -i script'.

builtins/printf.def
- change vbadd to only call FASTCOPY if the passed buffer length is
> 1
- if the `-v' option is supplied and `vbuf' is already non-null from a
previous `printf -v var' call, set vbuf[0]=0 explicitly instead of
relying on vbadd to do it -- vbadd may not be called.
- fix PRETURN macro to set vbuf[0] == 0 if vbuf is not freed. These
should fix problem reported by Elmar Stellnberger <estellnb@yahoo.de>
lib/readline/display.c
- fix update_line to deal with the case where col_lendiff > 0 (meaning
the new string takes up more screen real estate than the old) but
lendiff < 0 (meaning that it takes fewer bytes to do so). This can
happen when a multibyte prompt string is replaced with a longer one
containing only single-byte characters (e.g., when doing a reverse
i-search). Fixes gentoo bug reported by Peter Volkov
<torre_cremata@mail.ru>
builtins/read.def
- make sure we only print $PS2 if the standard input is a terminal
- new function, read_mbchar, to read a multibyte character so we
can make sure we read entire multibyte chars when `read -n' is
used, rather than bytes. Only called when -n is supplied.

builtins/printf.def
- change calls to asprintf and manually adding to vbuf to use calls
to vsnprintf against vbuf directly -- if the number of characters
to be written overflows the buffer, realloc the buffer and use
vsnprintf again. This should reduce the memory used by printf.
Idea from Yuya Katayama <yuya999@gmail.com>

number of elements as the upper bound
- brought in code to do case-modifying word expansions from
bash-4.0-devel branch, conditional on CASEMOD_EXPANSIONS

multibyte characters in array values are computed correctly. Fixes
bug reported by Wang Xin <wxinee@gmail.com>
7/10
----
jobs.c
- new function, maybe_give_terminal_to (old, new, flags), sets the
terminal pgrp to NEW if and only if it's currently set to OLD
- call maybe_give_terminal_to when the parent sets the terminal pgrp
to the pipeline pgrp in stop_pipeline, so we don't give the
terminal to the new job's pgrp unless it's currently owned by the
shell. Fixes race condition described by Joe Peterson
<joe@skyrush.com>, where parent bash may change tty pgrp after a
grandchild (interactive bash child of su) has changed it to
something else. The call to maybe_give_terminal_to makes explicit
a previously-implicit assumption
aclocal.m4
- remove dependency on writable /tmp by creating directories in
build directory
shell.c
- make changes to how bash sets no_line_editing and running_under_emacs
to deal with various emacs terminal emulators; use better check
for `eterm', since bash sends $PWD to eterm with control sequences
that confuse other programs. Problem reported by Micah Cowan

----
print_cmd.c
- break code that prints here-documents into two functions:
print_heredoc_header, which prints the operator and delimiter, and
print_heredoc_body, which prints the body text and closing delimiter
- change print_redirection to call print_heredoc_{header,body}
- sentinel variable, printing_connection, used when printing a command
of type `connection' (|, &&, ||, etc.)
- change print_redirection_list to save any here documents it finds
while printing a connection and save them in `deferred_heredocs'
- new function, print_deferred_heredocs, called from print_redirection
in the cm_connection case, calls print_heredoc_header for all the
here documents, then prints the operator (|, &&, ||, etc.), then
the here-document body. This preserves syntactic correctness; the
old code printed the control operator after the body of the here
document. Fixes bug reported by <buport@figpost.com>

execute_cmd.c
- new semaphore variable, executing_list, incremented every time a
list (command1;command2 or command1 || command2 or command1 &&
command2) is executed; used as sentinel for rest of shell
sig.c,builtins/evalstring.c
- set executing_list to 0 when throwing execution back to top level;
make sure to unwind-protect it in appropriate places
jobs.c
- if a pipeline is killed by SIGINT while executing a list (when
executing_list is non-zero), make sure the shell acts as if an
interrupt occurred. The behavior is dependent on the shell
compatibility level being > 32 (bash-4.0 and above)
9/23

<stephane_chazelas@yahoo.fr>
lib/readline/signals.c
- new variables to keep track of special characters corresponding to
SIGINT, SIGQUIT, and SIGTSTP
- new variable to keep track of whether tty is echoing control
characters corresponding to SIGINT, SIGQUIT, and SIGTSTP
- new function, _rl_echo_signal_char(int sig) to display the tty
special char generating SIGINT, SIGQUIT, or SIGTSTP. Based on
idea and code from Joe Peterson <joe@skyrush.com>
- call rl_echo_signal_char in rl_signal_handler: if the terminal
settings indicate it, readline will echo characters that generate
keyboard signals
lib/readline/rltty.c
- set _rl_intr_char, _rl_quit_char, and _rl_susp_char to special
characters that generate signals from keyboard
- set _rl_echoctl if ECHOCTL tty flag is set
lib/readline/rlprivate.h
- extern declarations for _rl_intr_char, _rl_quit_char, and

unwind_prot.h
- extern declaration for have_unwind_protects
builtins/evalstring.c
- in parse_and_execute_cleanup, make sure that we don't call
run_unwind_frame and expect it to decrement parse_and_execute_level

bashline.c
- add `~' to rl_filename_quote_characters so make_quoted_replacement
will call bash_quote_filename for words containing `~'. Then
bash_quote_filename can make choices based on that
- change quote_word_break_chars to backslash-quote the tilde in a
filename with a leading tilde that exists in the current directory,
since we want to inhibit tilde expansion in this case
execute_cmd.c
- call file_isdir from shell_execve instead of stat(2) directly
bashhist.c
- use file_exists and file_isdir primitives instead of calling stat
11/21

redir.c
- When undoing saving of non-standard file descriptors (>=3) using
file descriptors >= SHELL_FD_BASE, we set the saving fd to be

Partial fix for bug reported by Mike Frysinger <vapier@gentoo.org>
- in update_line, don't call insert_some_chars if that will start
before the last invisible character in the prompt string and not
draw the entire prompt string. More of the partial fix for bug
reported by Mike Frysinger <vapier@gentoo.org>
- fix update_line to adjust _rl_last_c_pos by wrap_offset when adding
characters beginning before the last invisible character in the
prompt. New code is same as previously existed in a different code
path. Rest of fix for bug from Mike Frysinger <vapier@gentoo.org>
- fix assignment of newline breaks (inv_lbreaks) to correctly account
for prompts longer than two screen lines containing invisible
characters. The assumption is that part of the invisible characters
are on the first line (prompt_invis_chars_first_line) and the
remainder are on the last (wrap_offset - prompt_invis_chars_first_line).
