                                 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

                                   ----
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

parse.y
        - change yy_stream_get to set interrupt_immediately before calling
          getc_with_restart when the shell is interactive.  This avoids the

        - 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

        - 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

          execute_shell_function in gen_shell_function_matches.  Fixes bug

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

          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())

          specifies, I believe (and the consensus of the austin-group list).
          This requires a few tests in read.tests to be changed: backslashes

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

lib/readline/isearch.c

        - 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

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

          to use it - rudimentary support for supporting the existing
          recursion using a stack of contexts, each with a reference to the
          previous

lib/readline/callback.c

          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

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),

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
        - return immediately from delete_job if jobs[index] is already NULL or
          if it has a null pipeline associated with it
        - in delete_job, if find_last_proc returns NULL, don't try to call
          bgp_delete

doc/bash.1
        - patch from Tim Waugh to replace some literal single quotes with
          \(aq, the groff special character for it

jobs.c
        - in realloc_jobs_list, make sure to zero out slots after j_lastj
          in the new list

parse.y
        - when calling parse_matched_pair on a $(...) command substitution,
          don't pass the P_DQUOTE flag so that single quotes don't get
          stripped from $'...' inside the command substitution.  Bug report
          and fix from Mike Stroyan <mike.stroyan@hp.com>

jobs.c
        - start maintaining true count of living children in js.c_living
        - call reset_current in realloc_jobs_list, since old values for current
          and previous job are most likely incorrect
        - 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
        - add some more itrace messages about non-null jobs after j_lastj in
          jobs array

                                   ----
jobs.c
        - add logic to make_child to figure out when pids wrap around
        - turn second argument to delete_job into flags word, added flag to
          prevent adding proc to bgpids list

                                   1/13
                                   ----
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

subst.c
        - in parameter_brace_expand, if extracting ${#varname}, only allow
          `}' to end the expansion, since none of the other expansions are
          valid.  Fixes Debian bug reported by Jan Nordhorlz <jckn@gmx.net>

                                   ----
parse.y
        - in parse_matched_pair, protect all character tests with the MBTEST
          macro
        - in parse_dparen, take out extra make_word after call to alloc_word_desc
          (mem leak)

          parse_matched_pair call when encountering a single or double quote
          inside a ``-style command substitution

execute_cmd.c
        - add call to QUIT at beginning of execute_command_internal; better
          responsiveness to SIGINT

                                   1/21
                                   ----
lib/readline/bind.c
        - change rl_invoking_keyseqs_in_map to honor the setting of
          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.

                                   ----
quit.h
        - wrap QUIT macro in do...while(0) like other compound statement
          macros
        - CHECK_TERMSIG define (placeholder for now); future use will be to
          handle any received signals that should  cause the shell to
          terminate (e.g., SIGHUP)

{input,jobs,nojobs}.c
        - add calls to CHECK_TERMSIG where appropriate (reading input and
          waiting for children)
        - include quit.h if necessary

                                   1/25
                                   ----
parse.y
        - undo change that makes `)' in a compound assignment delimit a token.
          It messes up arithmetic expressions in assignments to `let', among
          other things

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,
          as was intended

parse.y,builtins/read.def
        - set terminate_immediately to non-zero value when reading interactive
          input, as is done with interrupt_immediately

lib/readline/complete.c
        - move call to filename dequoting function into
          rl_filename_completion_function; call only if directory completion
          hook isn't set.  This means that directory-completion-hook now needs
          to dequote the directory name.  We don't want to dequote the directory
          name before calling the directory-completion-hook.  Bug reported by
          Andrew Parker <andrewparker@bigfoot.com>

bashline.c
        - add necessary directory name dequoting to bash_directory_expansion
          and bash_directory_completion_hook

lib/readline/doc/rltech.texi
        - add note to description of rl_directory_completion_hook that it
          needs to dequote the directory name even if no other expansions are
          performed

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
          and declare do not require their variable operands to be valid
          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
          things like ACLs, read-only file systems, file flags, and so on.

lib/sh/Makefile.in,Makefile.in
        - add necessary entries for eaccess.[co]

test.c
        - change calls to test_stat to call sh_stat

{test,general}.c

          bash_default_completion
        - if no_empty_command_completion is set, bash does not attempt command
          word completion even if not at the beginning of the line, as long

lib/readline/rlprivate.h
        - new extern declaration for _rl_term_forward_char

lib/readline/display.c
        - in _rl_move_cursor_relative, use `dpos' instead of `new' when
          deciding whether or not a CR is faster than moving the cursor from
          its current position
        - in _rl_move_cursor_relative, we can use _rl_term_forward_char to
          move the cursor forward in a multibyte locale, if it's available.
          Since that function doesn't have a handle on where the cursor is in
          the display buffer, it has to output a cr and print all the data.
          Fixes rest of problem reported by Egmont Koblinger
        - change variable denoting the position of the cursor in the line buffer
          from c_pos (variable local to rl_redisplay) to cpos_buffer_position
          (variable local to file) for future use by other functions

lib/sh/getcwd.c
        - new function, _path_checkino, checks whether the inode corresponding
          to the path constructed from the first two arguments is the same as
          the inode number passed as the third argument
        - if BROKEN_DIRENT_D_INO is defined, meaning the d_ino/d_fileno
          member of struct dirent doesn't contain valid values, use
          _path_checkino instead of directly comparing against d_fileno.

                                 --------
array.c
        - fix array_subrange to separate elements in returned string with
          first char of $IFS if QUOTED is non-zero, since this indicates
          the caller used ${array[@]:foo}.  Fixes bug reported by Lea

lib/readline/display.c
        - use sentinel variable set at end of init_line_structures to decide
          whether to call it from rl_redisplay, since early SIGWINCH on
          Mac OS X that hits during this function can cause _rl_wrapped_line
          to be referenced before initialization.  Fix for bug reported by
          Len Lattanzi <llattanzi@apple.com>

subst.[ch]
        - skip_to_delim is now compiled into the shell all the time, not just
          when readline is linked in

subst.c
        - use skip_to_delim to find the `/' denoting the end of a pattern
          in pattern substitution, since it knows more shell syntax than
          quoted_strchr and understands multibyte characters.  Fixes bug
          reported by Dmitry V Golovashkin <Dmitry.Golovashkin@sas.com>

          the WORD

subst.h
        - change extern declaration for expand_prompt_string to add third arg

bashline.c
        - pass W_NOCOMSUB as third argment to expand_prompt_string when
          calling from bash_directory_completion_hook, since we don't want
          to do command substitution from the completion code

doc/Makefile.in
        - added an `install_builtins' rule to install the builtins.1 man page,
          preprocessing it with sed to force `.so man1/bash.1', which some
          versions of man require.  Suggestion from Peter Breitenlohner
          <peb@mppmu.mpg.de>
        - new target `install_everything' that will install normal documentation
          and builtins man page
        - changed uninstall target to remove bash_builtins page from man
          directory

lib/readline/vi_mode.c
        - new function, rl_vi_insert_mode, which calls rl_vi_start_inserting
          to make sure the value of `last command to repeat' is set correctly.
          Fix from Thomas Janousek <tjanouse@redhat.com>
        - add support for redoing inserts made with the `I' command.  Fix

builtins/read.def
        - change timeout behavior when not reading from a tty device to save
          any partial input in the variable list, but still return failure.
          This also causes variables specified as arguments to read to be
          set to null when there is no input available.  Fix inspired by

builtins/fc.def
        - change computation of last_hist to use remember_on_history instead
          of a hard-coded `1'.  This keeps fc -l -1 in PROMPT_COMMAND from
          looking too far back

bashline.c
        - change command_word_completion_function to use the word completion
          found by readline, which matters only when ignoring case is on
          and the completion found in the file system differs in case from
          the text the user typed (this is what readline does for normal
          filename completion).  Fixes issue reported by Jian Wang

          readline variables based on a passed flags value (COPT_FILENAMES,

          word indicates word completion is in progress

pcomplete.h

builtins/evalstring.c
        - fixed typo in parse_string (ostring used uninitialized).  Bug
          reported by Andreas Schwab <schwab@suse.de>

subst.c
        - fix return value of parameter_brace_expand to set the
          W_HASQUOTEDNULL flag in the returned WORD_DESC * if the return value
          from parameter_brace_remove_pattern is a quoted null string.  Fixes
          bug reported by Andreas Schwab <schwab@suse.de>

builtins/read.def
        - change read -t 0 to return success if there is input available to be
          read -- allows scripts to poll for input.  Uses input_avail libsh
          function

                                    ---
externs.h
        - fix extern fpurge declaration -- use HAVE_DECL_FPURGE instead of
          NEED_FPURGE_DECL, since the former is set by `configure'

builtins/return.def
        - call no_options, as Posix requires.  This also has the effect of
          disallowing negative return values unless they're prefixed by `--'

builtins/bind.def
        - add an error message when bind is used without line editing active,
          instead of just returning an error status

variables.c
        - make sure make_local_variable never creates visible variables with
          a value, whether or not a variable with the same name existed in a
          previous context.  This is consistent with ksh93.  Fix from

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)

redir.c

          the errno is EBADF, if the redirection error (e.g., NOCLOBBER)

          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>

          gentoo/freebsd

parse.y
        - in parse_comsub, allow comments if we are ready to read a
          reserved word (tflags & LEX_RESWDOK), haven't read anything from
          one yet (lex_rwlen == 0) and the current character is a '#'

parse.y
        - new lex flag for parse_comsub: LEX_INWORD.  Turn it off when
          we see a shell break character; turn it on or keep it on when
          not a break character.  Keep track of word length (reset to 0
          when we turn on LEX_INWORD when it was off).
        - don't use COMMENT_BEGIN in parse_comsub any more; test
          whether or not LEX_INWORD is set and lex_wlen == 0 in addition
          to tests for LEX_RESWDOK and lex_rwlen.  Comments are valid
          when at the start of a word
        - move LEX_PASSNEXT code to the top of parse_comsub, so the rest
          of the function doesn't have to check for the flag at different
          places

parse.y
        - in parse_comsub, when looking for a reserved word (LEX_RESWDOK
          non-zero), and in a case statement, we can see either an esac
          or a pattern list.  We handle an esac separately.  We should
          turn off LEX_RESWDOK if we see anything but a newline, since
          we'll be reading a pattern list.  Other part of fix for bug
          reported by Mike Frysinger <vapier@gentoo.org> (rest of fix

          Lefevre <vincent@vinc17.org> (2/24/2009)

parser.h
        - add PST_REDIRLIST flag, notes that parser is currently parsing a
          redirection list preceding a simple command

        - parameter_brace_expand_word now takes an extra `pflags' argument to
          pass down to param_expand; changed callers

        - tentative fix to glob_filename to compensate for glob_vector putting
          null pathname at front of result vector when dflags&GX_NULLDIR.
          Current fix manually removes empty string element from front of
          result vector; a better fix would be to use a flag so glob_vector
          doesn't add it at all.  Augments patch from 4/28, which appears to

          are introduced by the Control Sequence Indicator (CSI) and
          contain a defined set of characters.  Insert, End, Page Up and so
          on are CSI sequences.  Report and code from Andy Koppe

          then fp == STDERR, the default mode
        - new function xtrace_init, sets xtrace_fd == -1 and xtrace_fp = stderr
        - new function xtrace_set (fd, fp), sets xtrace_fd and xtrace_fp

lib/sh/fnxform.c
        - new file with two public function: fnx_tofs and fnx_fromfs.
          Primarily intended for use on MacOS X, they use iconv to convert
          between whatever the current locale encoding is and "UTF-8-MAC",
          a special encoding on OS X in which all characters are
          decomposed unicode, as the HFS+ filesystem stores them.  These
          functions return a pointer to a local buffer, allocated once and
          resized as necessary, to avoid too many allocations; callers
          should not free the return value, since it may be the string
          passed

Makefile.in
        - make sure LIBICONV is set by autoconf (@LIBICONV@) and added to
          list of link libraries

externs.h
        - new extern declarations for fnx_fromfs and fnx_tofs

lib/glob/glob.c
        - convert the filename read using readdir() in glob_vector() using
          fnx_fromfs and use that value in the call to strmatch.  This
          ensures that we're using the precomposed Unicode value of the

          after rl_point that match in both the completion to be inserted
          and the word being completed.  It means that completing
          `Makefile' with the cursor after the `e' results in `Makefile'
          instead of `Makefilefile'.  Inspired by an idea from Jared
          Yanovich <phierunner@comcast.net> from back in 2004

lib/readline/rlprivate.h

          Lattarini <stefano.lattarini@gmail.com>

braces.c
        - fix expand_seqterm so that a non-zero-prefixed term that's longer
          than a zero-prefixed term determines the length of each term
          in the brace-expanded sequence.  This means that things like
          {01..100} will have three digits in all the elements of the
