				 ---------

[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

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
	- new flag #defines to use for evaluating assignment statements

{subst,variables}.c, builtins/{declare,read}.def
	- change callers of assign_array_element and bind_array_variable
	- change do_compound_assignment to understand assignment flags
	- change do_assignment_internal to set assignment flags and pass them
	  to underlying functions

pcomplete.c,builtins/{declare,read}.def
	- fix callers of assign_array_var_from_string, assign_array_var_from_word_list

variables.[ch]
	- make_variable_value now takes a new `flags' argument
	- make_variable_value now understands how to append to a particular
	  variable, using the old value
	- bind_variable_value now takes a new `flags' argument
	- change make_variable_value to understand ASS_APPEND flag
	- bind_variable now takes a new `flags' argument
	- bind_variable_internal now takes a new `flags' argument

arrayfunc.c
	- change callers of make_variable_value to add flags arg

builtins/declare.def
	- change callers of bind_variable_value to add flags arg

{execute_cmd,mailcheck,pcomplete,shell,subst,variables}.c,parse.y
builtins/{cd,command,declare,getopts,read,set,setattr}.def
	- change callers of bind_variable to add flags arg

variables.c
	- change callers of bind_variable_internal
	- change bind_variable_internal to pass assignment flags on to
	  make_variable_value
	- change assign_in_env to treat `var+=value' like `var=value'

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

				   11/12
				   -----
lib/readline/display.c
	- make sure prompt_physical_chars and prompt_invis_chars_first_line
	  are reset to 0 if the prompt string passed to rl_expand_prompt is
	  NULL or empty

				   11/14
				   -----
{configure,config.h}.in
	- check for `raise', define HAVE_RAISE if available

lib/intl/dcigettext.c
	- make sure `raise' is defined if HAVE_RAISE is not before
	  eval-plurah.h is included

lib/malloc/trace.c
	- put extern declaration for imalloc_fopen inside the MALLOC_TRACE
	  #ifdef

				   11/16
				   -----
lib/intl/Makefile.in
	- make sure SHELL is defined to cpp

lib/intl/dcigettext.c
	- make sure we use getcwd() even if HAVE_GETCWD is not defined after
	  including config.h; if SHELL is defined, #define HAVE_GETCWD

				   11/18
				   -----
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

				   11/20
				   -----
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
	- make sure timestamp is initialized to NULL in rl_maybe_save_line

				   12/1
				   ----
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

				   12/2
				   ----
lib/glob/xmbsrtowcs.c
	- change xmbsrtowcs to handle the one case where malloc can fail
	  (though it should not matter) -- don't try to free a null pointer

				   12/9
				   ----
subst.c
	- fix get_var_and_type to handle var[@], where `var' is a scalar
	  variable, identically to var -- all calling expansions can now
	  handle var[@] like var.  Bug reported by agriffis@gentoo.org

				   12/10
				   -----
lib/readline/bind.c
	- make new-style "\M-x" keybindings obey `convert-meta' settings
	  (bug reported by twaugh@redhat.com)

				   12/14
				   -----
builtins/set.def
	- added description of `-' option to help text

builtins/shopt.def
	- fix bug that caused `gnu_errfmt' to not be compiled in unless
	  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
	  (sithglan@stud.uni-erlangen.de)

				   ----
command.h
	- new word flag: W_HASQUOTEDNULL

make_cmd.c
	- new function to allocate a WORD_DESC * without doing anything with a
	  containing string:  alloc_word_desc

make_cmd.h
	- extern declaration for alloc_word_desc

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

dispose_cmd.h
	- extern declaration for dispose_word_desc

subst.c
	- change some places to use alloc_word_desc
	- make same changes to word_list_quote_removal as were made to
	  word_list_split
	- set W_HASQUOTEDNULL when a word is created with w->word[0] ==
	  CTLNUL and w->word[1] == '\0'

subst.c
	- parameter_brace_expand_word now returns a WORD_DESC * -- changed
	  callers to understand
	- parameter_brace_expand_indir now returns a WORD_DESC * -- changed
	  callers to understand
	- parameter_brace_expand_rhs now returns a WORD_DESC * -- changed
	  callers to understand
	- remove W_HASQUOTEDNULL from a word's flags when remove_quoted_nulls
	  is called on the word's enclosed string

				   1/15
				   ----
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

				   1/16
				   ----
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

				   1/20
				   ----
lib/readline/history.c
	- fix replace_history_entry, remove_history to return NULL if
	  passed index is < 0

				   1/22
				   ----
lib/sh/netconn.c
	- fix isnetconn() to understand that getpeername can return ENOTCONN
	  to indicate that an fd is not a socket

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

				   1/31
				   ----
arrayfunc.c
	- in array_value_internal, return NULL right away if the variable's
	  value is NULL, instead of passing a null string to add_string_to_list

jobs.h
	- new struct to hold stats and counters for child processes and jobs
	- change some uses of global and static variables to use members of
	  new struct (struct jobstats)

				    2/2
				    ---

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) \
		 (echo 6))

	  work right

				    2/8
				    ---
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
	- change delete_job to call bgp_add on the last proc of the job being
	  deleted
	- change delete_all_jobs and wait_for_background_pids to call bgp_clear

support/shobj-conf
	- change the solaris-gcc stanza so that it auto-selects the appropriate
	  options for ld depending on which `ld' gcc says it's going to run

				   2/11
				   ----
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
	- set $_ from the environment if we get it there, set to $0 by
	  default if not in env

doc/{bashref.texi,bash.1}
	- a couple of clarifying changes to the description of $_ based on
	  comments from Glenn Morris <gmorris+mail@ast.cam.ac.uk>

shell.c

builtins/cd.def
	- implement posix requirement that `pwd -P' set $PWD to a directory
	  name containing no symlinks
	- add new function, setpwd(), just sets (and changes exported value)
	  of PWD

doc/bashref.texi
	- add note to posix mode section about pwd -P setting $PWD

doc{bash.1,bashref.texi}
	- added note that BASH_ARGC and BASH_ARGV are only set in extended
	  debug mode
	- expand description of extdebug option to include everything changed
	  by extended debug mode

pathexp.h
	- new flag macro, FNMATCH_IGNCASE, evaluates to FNM_CASEFOLD if the
	  match_ignore_case variable is non-zero

execute_cmd.c
	- new variable, match_ignore_case
	- change call to strmatch() in execute_case_command so it includes
	  FNMATCH_IGNCASE

test.c
	- change call to strmatch() in patcomp() so that pattern matching
	  calls for [[ ... ]] obey the match_ignore_case variable

lib/sh/shmatch.c
	- if match_ignore_case is set, enable REG_ICASE in the regexp match
	  flags

builtins/shopt.def
	- new settable option, `nocasematch', controls the match_ignore_case
	  variable.  Currently alters pattern matching for case and [[ ... ]]
	  commands (==, !=, and =~ operators)

doc/{bashref.texi,bash.1}
	- updated descriptions of [[ and case to include reference to
	  nocasematch option

				   2/22

builtins/mkbuiltins.c
	- add `times' to the list of posix special builtins

				   2/23

builtins/cd.def
	- posix mode no longer turns on effect of -P option on $PWD if a
	  directory is chosen from CDPATH

doc/bashref.texi
	- clarified that in posix mode, reserved words are not alias expanded
	  only in a reserved word context
	- removed item about cd, $CDPATH, and -P from posix mode section

				   2/24

builtins/reserved.def
	- minor cleanups to the description of `if'

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

configure.in

bashline.c
	- make bash_directory_expansion a void function, since it doesn't have
	  any return value

				    3/9
				    ---
builtins/read.def
	- when testing for a pipe, use `fd' instead of hard-coding 0, since we
	  can read from other file descriptors now

lib/sh/zread.c
	- in zsyncfd, only set lind and lused to 0 if the lseek succeeds.
	  If the lseek fails, we might steal input from other programs, but
	  a failed lseek won't cause us to erroneously discard input

				   3/11

builtins/evalstring.c
	- don't allow parse_and_execute to short-circuit and call exec() if
	  the command's return value is being inverted

				   3/15
				   ----
builtins/printf.def
	- new macro PC to call putchar and increment number of chars printed -
	  fixes bug in computation of value for %n format char
	- `tw' is now a global var so printstr can modify it using PC()
	- convert PF macro to use asprintf into a local buffer
	  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

				   3/16
				   ----
parse.y
	- fix bug in prompt string decoding that caused a core dump when PS1
	  contained \W and PWD was unset (null pointer deref)

builtins/printf.def
	- changed -v var behavior so it stores partial output into the named
	  variable upon an error

				   3/24

lib/readline/bind.c
	- bool_to_int now takes a `const char *' argument

support/{printenv,recho,zecho}.c
	- include config.h
	- include "bashansi.h" for appropriate extern function declarations

configure.in
	- on MacOS X 10.4, compensate for loader not allowing static library
	  to override existing system dynamic library when compiling -dynamic
	  (affects readline and history libraries); so use absolute pathname
	  instead of -lreadline as library name

lib/glob/{glob,sm_loop,smatch}.c
	- make sure to cast arguments to (char *)  or (unsigned char *) as
	  appropriate to avoid gcc4 warnings

lib/glob/smatch.c
	- collsym (single-byte version) now takes a (CHAR *) first argument to
	  match callers; cast argument to strncmp appropriately

lib/sh/snprintf.c
	- fix ldfallback and dfallback to handle width and precision specs in
	  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
	- fix * code to deal with a negative precision by treating it as if
	  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
	- new function, rl_vi_rubout, to rl_rubout as rl_vi_delete is to
	  rl_delete; saves deleted text for possible reinsertion as with any
	  vi-mode `text modification' command (fixes problem with `X' reported
	  by beat.wieland@gmx.ch)

lib/readline/vi_keymap.c
	- bind `X' in vi command mode to rl_vi_rubout

lib/readline/funmap.c
	- add a bindable `vi-rubout' command, runs rl_vi_rubout

lib/readline/text.c
	- rewrote internals of _rl_rubout_char to make structure cleaner

lib/readline/{complete,text}.c
	- changed code to remove #ifdef HANDLE_MULTIBYTE where possible

				   4/11
				   ----
subst.c
	- change match_upattern and match_wpattern to check whether or not the
	  supplied pattern matches anywhere in the supplied string, prefixing
	  and appending the pattern with `*' if necessary.  If it doesn't we
	  can short-circuit immediately rather than waste time doing up to
	  N-1 unsuccessful calls to strmatch/wcsmatch (which kills for long
	  strings, even if the pattern is short)

				   4/12

configure.in
	- make sure the special case for MacOS X 10.4 only kicks in if the
	  `--with-installed-readline' option isn't supplied

lib/readline/{callback,readline,signals}.c
	- make sure rl_prep_term_function and rl_deprep_term_function aren't
	  dereferenced if NULL (as the documentation says)

builtins/mkbuiltins.c
	- don't bother with the special HAVE_BCOPY code; just use straight
	  assignments

builtins/ulimit.def
	- use _POSIX_PIPE_BUF in pipesize() if it's defined and PIPE_BUF is
	  not

				   4/13

	  rl_callback_handler_remove

				   4/29

config-top.h
	- DONT_REPORT_SIGPIPE is now on by default, since it apparently

	  kernels (ones that apparently schedule children to run before their
	  parent)

				   4/30

builtins/caller.def
	- add call to no_options, so it can handle `--' option

support/shobj-conf
	- darwin 8 needs the same LDFLAGS setting as darwin 7

parse.y
	- in save_parser_state, make sure we cast the return value from
	  xmalloc() to the right type
	- remove casts to (char *) in calls to yyerror()

lib/readline/signals.c
	- make SIGQUIT and SIGALRM code conditional on their definition
	- use raise() to send a signal if we don't have kill()

lib/readline/display.c
	- some MS-DOS and MINGW changes from the cygwin and mingw folks

config.h.in
	- add HAVE_PWD_H for <pwd.h>
	- add HAVE_FCNTL, HAVE_KILL for respective system calls
	- add HAVE_GETPW{ENT,NAM,UID} for passwd functions

configure.in
	- add check for <pwd.h>
	- add checks for fcntl, kill system calls
	- add checks for getpw{ent,nam,uid} C library functions
	- pass a flag indicating we're cross compiling through to
	  CFLAGS_FOR_BUILD in Makefile.in

lib/readline/complete.c
	- guard inclusion of <pwd.h> with HAVE_PWD_H
	- don't provide a missing declaration for getpwent if we don't have it
	- guard calls to {get,end}pwent with HAVE_GETPWENT

lib/readline/shell.c
	- guard inclusion of <pwd.h> with HAVE_PWD_H
	- guard inclusion of <fcntl.h> with HAVE_FCNTL_H
	- don't provide a missing declaration for getpwuid if we don't have it

				   5/11
				   ----
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

				   5/17
				   ----

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

lib/readline/readline.c
	- new variable, _rl_dispatching_keymap, keeps track of which keymap
	  we are currently searching
	- functions to allocate and deallocate contexts for reading multi-char
	  key sequences

				   5/18
				   ----
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
	- if an exec fails and the execfail option is set, don't call
	  restart_job_control unless the shell is interactive or job_control
	  is set

jobs.c
	- add a run-time check for WCONTINUED being defined in header files
	  but rejected with EINVAL by waitpid().  Fix from Maciej Rozycki
	  <macro@linux-mips.org>

				   6/20

	- ditto for calls to history_expand_line_internal

				   6/23
				   ----
doc/bashref.texi
	- remove extra blank lines in @menu constructs

variables.c
	- assign export_env to environ (extern char **) every time it changes
	  (mostly in add_to_export_env define), so maybe getenv will work on
	  systems that don't allow it to be replaced

				   6/29
				   ----
bashline.c
	- in bash_directory_completion_hook, be careful about not turning `/'
	  into `//' and `//' into `///' for benefit of those systems that treat
	  `//' as some sort of `network root'.  Fix from Eric Blake
	  <ebb9@byu.net>

lib/readline/complete.c
	- in to_print, do the right thing after stripping the trailing slash
	  from full_pathname: // doesn't turn into /, and /// doesn't become
	  //.  Fix from Eric Blake <ebb9@byu.net>

				   6/30
				   ----
lib/malloc/trace.c
	- include <unistd.h> if it's available for a definition of size_t

jobs.c
	- in wait_for, if a child process is marked as running but waitpid()
	  returns -1/ECHILD (e.g., when the bash process is being traced by
	  strace), make sure to increment c_reaped when marking the child as
	  dead
	- in without_job_control, make sure to close the pgrp pipe after
	  calling start_pipeline

				    7/1

Makefile.in
	- only remove pathnames.h when the other files created by running
	  configure are removed (e.g., Makefile).  Fix from William Park

lib/sh/shquote.c
	- since backslash-newline disappears when within double quotes, don't
	  add a backslash in front of a newline in sh_double_quote.  Problem
	  reported by William Park

jobs.c
	- in notify_of_job_status, don't print status messages about
	  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>
	- pay attention to hist_last_line_pushed in expand_and_print_history()
	  so we don't delete an entry pushed by history -s

				    7/4

print_cmd.c
	- fix print_arith_for_command to not print so many blanks between
	  expressions in ((...))

command.h
	- new word flag: W_DQUOTE.  Means word should be treated as if double
	  quoted

make_cmd.c
	- add W_DQUOTE to word flags in make_arith_for_expr

parse.y
	- add W_DQUOTE to word flags for (( ... )) arithmetic commands

subst.c
	- don't perform tilde expansion on a word with W_DQUOTE flag set
	- don't perform process substitution on a word with W_DQUOTE flag set

arrayfunc.c
	- expand an array index within [...] the same way as an arithmetic
	  expansion between (( ... ))

lib/readline/input.c
	- use getch() instead of read() on mingw

lib/readline/readline.c
	- add a few key bindings for the arrow keys on mingw

lib/readline/rldefs.h
	- if on mingw, define NO_TTY_DRIVER

lib/readline/rltty.c
	- compile in the stub functions for _rl_{disable,restore}_tty_signals
	  if on mingw
	- compile in stub function for rl_restart_output on mingw
	- make sure enough functions and macros are defined to compile if
	  NO_TTY_DRIVER is defined (lightly tested - builds on MacOS X, at
	  least)

				    7/7

command.h
	- add a `flags' member to the PATTERN_LIST structure

make_cmd.c
	- intialize the `flags' member of a PATTERN_LIST when it's created

builtins/psize.c

	  mess up the shell's parser state

bashline.c
	- change command_subst_completion_function to suppress appending

variables.c
	- use get_variable_value instead of direct reference to value_cell
	  in make_variable_value when appending to the current value, so
	  references to array variables without subscripts will be equivalent
	  to element 0

lib/readline/text.c

	  characters where appropriate

general.h
	- new #define, FS_READABLE, indicates file is readable by current

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
	  scripts whose names are supplied as arguments on the command line)
	- change find_path_file to look for readable files -- source requires
	  it
	- change find_in_path_element to do the right thing when FS_READABLE

jobs.c
	- in kill_pid, if asked to killpg a process or pgrp whose pgrp is
	  recorded as the same as the shell's, just call killpg and let the
	  chips fall where they may -- there may be other processes in that
	  pgrp that are not children of the shell, so killing each process
	  in the pipeline will not do a complete job, and killpg'ing each
	  such process will send too many signals in the majority of cases

builtins/cd.def
	- in posix mode, pwd needs to check that the value it prints and `.'
	  are the same file

builtins/read.def
	- if reading input from stdin in a non-interactive shell and calling

	  not in posix mode

jobs.c
	- in posix mode, don't have start_job print out and indication of
	  whether the job started by `bg' is the current or previous job
	- change start_job to return success if a job to be resumed in the
	  background is already running.  This means that bg won't fail when
	  asked to bg a background job, as SUSv3/XPG6 requires
	- new function, init_job_stats, to zero out the global jobstats struct

{jobs,nojobs}.c
	- change kill_pid to handle pids < -1 by killing process groups

jobs.h
	- extern declaration for init_job_stats

lib/readline/history.c
	- check whether or not the history list is null in remove_history

builtins/history.def
	- delete_last_history is no longer static so fc builtin can use it

builtins/fc.def
	- use free_history_entry in fc_replhist instead of freeing struct
	  members individually
	- call delete_last_history from fc_replhist instead of using inline
	  code
	- if editing (-l not specified), make sure the fc command that caused
	  the editing is removed from the history list, as POSIX specifies

builtins/kill.def
	- just call kill_pid with any pid argument and let it handle pids < -1
	  This is the only way to let kill_pid know whether a negative pid or
	  a job spec was supplied as an argument to kill

builtins/fg_bg.def
	- force fg_bg to return EXECUTION_SUCCESS explicitly if called by bg
	  and start_job returns successfully

lib/readline/search.c
	- if in vi_mode, call rl_free_undo_list in make_history_line_current
	  to dispose of undo list accumulated while reading the search string
	  (if this isn't done, since vi mode leaves the current history
	  position at the entry which matched the search, the call to
	  rl_revert_line in rl_internal_teardown will mangle the matched
	  history entry using a bogus rl_undo_list)
	- call rl_free_undo_list after reading a non-incremental search string
	  into rl_line_buffer -- that undo list should be discarded

lib/readline/rlprivate.h

eval.c
	- call QUIT before calling dispose_command on current_command after
	  the  `exec_done' label.  If we dispose current_command first, the

lib/readline/vi_mode.c
	- when entering vi_command mode for the first time, free any existing

	  command.  This is how POSIX.2 says `U' should work (and the test
	  suite tests for it)

	- 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

lib/readline/readline.h
	- new extern declaration for rl_reset_screen_size

lib/readline/doc/rltech.texi

variables.c
	- if readline is being used, compile in a special var function for

	- make sure error cases free memory and run any unwind-protects to
	  avoid memory leaks

				   12/10

execute_cmd.c
	- change execute_command_internal to set $PIPESTATUS for ((...)) and
	  [[ ... ]] commands

doc/{bash.1,bashref.texi,version.texi}
	- add documentation for ulimit -[iqx] and bump revision date

parse.y
	- make sure parse_compound_assignment saves and restores the
	  PST_ASSIGNOK parser state flag around its calls to read_token.
	  Fixes bug reported by Mike Frysinger

				   12/13
				   -----
parse.y
	- change parse_compound_assignment to save and restore the value of
	  last_read_token.  Not sure why it was set unconditionally in the
	  first place after parsing the complete compound assignment

				   12/14
				   -----
lib/readline/text.c
	- don't use return value of rl_kill_text (which always succeeds and
	  returns the number of characters killed) in rl_delete as an indication
	  of success or failure
	- ditto for return value of rl_delete_text

lib/readline/readline.c
	- don't return the value of the called readline function as the return
	  value from _rl_dispatch_subseq; -1 means something different to the
	  callers (return 0 all the time to indicate that a readline function
	  was found and dispatched).  Fix from Andreas Schwab for <DEL><DEL>
	  bug in callback interface first reported by Mike Frysinger

execute_cmd.c
	- fixed a typo in execute_case_command

				   12/15
				   -----
aclocal.m4
	- add check for wctype() to BASH_CHECK_MULTIBYTE, define HAVE_WCTYPE

config.h.in
	- add HAVE_WCTYPE #define

config-bot.h
	- add HAVE_WCTYPE to the set of checks for HANDLE_MULTIBYTE.  This
	  should catch the deficient NetBSD multibyte support

				   12/16
				   -----
parse.y
	- use CTLESC instead of literal '\001' when decode_prompt_string
	  prefixes RL_PROMPT_START_IGNORE and RL_PROMPT_END_IGNORE

				   12/20
				   -----
lib/readline/display.c
	- don't treat RL_PROMPT_START_IGNORE specially inside a sequence of
	  ignored characters
	- 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'
	  (RL_PROMPT_START_IGNORE)

				   12/21
				   -----
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
	- documented expansions for word and patterns in case statement

builtins/ulimit.def,doc/{bashref.texi,bash.1}
	- added new -e and -r (nice and rtprio) options to ulimit; documented
	  them

				   12/26
				   -----
variables.c
	- use `hmax' instead of `num' in sv_histsize to avoid integer overflow
	  problems with intmax_t

builtins/read.def
	- add unwind-protect to restore rl_attempted_completion_function in
	  case of a timeout

{bashline,variables}.c
	- move initialization of HISTSIZE from initialization path to
	  load_history, so it can be overridden by a value assigned in a
	  startup file

lib/readline/misc.c
	- add a missing `return r' so that rl_digit_loop returns a meaningful
	  value

lib/readline/{bind,callback,display,isearch,rltty,search,text,vi_mode}.c
	- minor cleanups to satisfy compiler warnings, mostly removing unused
	  variables

				   12/27
				   -----
support/Makefile.in
	- add LIBS_FOR_BUILD support; defaults to ${LIBS}

Makefile.in
	- add LIBS_FOR_BUILD with no default value; use when linking programs
	  using CC_FOR_BUILD (e.g., bashversion)

				   12/28
				   -----
lib/readline/bind.c
	- fix rl_translate_keyseq bad translation of \M-\C-x sequences

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
	  semantics

tests/new-exp.tests
	- change tests to remove all ${pat//#rep} and ${pat//%rep}
	  expansions, since they don't mean the same thing anymore

				   12/29
				   -----
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
	- 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

				 1/7/2006
				 --------
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

				    1/9
				    ---
support/mksignames.c
	- make sure to include <signal.h> to get right value of NSIG from
	  (usually) <sys/signal.h>

				   1/10
				   ----
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

				   1/11
				   ----
bashjmp.h
	- new value for second argument to longjmp: SIGEXIT.  Reserved for
	  future use

				   1/12
				   ----
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>

				   1/14
				   ----
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

				   1/15
				   ----
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>

				   1/17
				   ----
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)

				   1/18
				   ----
parse.y
	- in parse_matched_pair, add P_ALLOWESC to flags passed to recursive
	  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.

				   1/24
				   ----
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

				   1/26
				   ----
doc/{bash.1,bashref.texi}
	- reworded the POSIX standard references to remove mention of POSIX.2
	  or 1003.2 -- it's all the 1003.1 standard now.  Recommended by
	  Arnold Robbins

				   1/27
				   ----
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

				   1/28
				   ----
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
	- change calls to test_eaccess to call sh_eaccess

externs.h
	- new extern declaration for sh_eaccess

test.[ch]
	- remove test_stat and test_eaccess

				   1/29
				   ----
braces.c
	- make change from 1/28 dependant on CSH_BRACE_COMPAT not being
	  defined (since old bash behavior is what csh does, defining
	  CSH_BRACE_COMPAT will produce old bash behavior)

				   1/30
				   ----
bashline.c
	- last argument of bash_default_completion is now a flags word:
	  DEFCOMP_CMDPOS (in command position) is only current value
	- attempt_shell_completion now computes flags before calling
	  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
	  as the word to be completed is empty and start == end (catches
	  beginning of line and all whitespace preceding point)

				    2/4
				    ---
lib/readline/display.c
	- change _rl_make_prompt_for_search to use rl_prompt and append the
	  search character to it, so the call to expand_prompt in rl_message
	  will process the non-printing characters correctly.  Bug reported
	  by Mike Stroyan <mike.stroyan@hp.com>

				    2/5
				    ---
lib/readline/display.c
	- fix off-by-one error when comparing against PROMPT_ENDING_INDEX,
	  which caused a prompt with invisible characters to be redrawn one
	  extra time in a multibyte locale.  Change from <= to < fixes
	  multibyte locale, but I added 1 to single-byte definition of
	  PROMPT_ENDING_INDEX (worth checking) to compensate.  Bug reported
	  by Egmont Koblinger <egmont@uhulinux.hu>

				    2/8
				    ---
lib/readline/terminal.c
	- call _emx_get_screensize with wr, wc like ioctl code for consistency
	- new function, _win_get_screensize, gets screen dimensions using
	  standard Windows API for mingw32 (code from Denis Pilat)
	- call _win_get_screensize from _rl_get_screen_size on mingw32

lib/readline/rlconf.h
	- define SYS_INPUTRC (/etc/inputrc) as system-wide default inputrc
	  filename

support/shobj-conf
	- changes to make loadable builtins work on MacOS X 10.[34]

builtins/pushd.def
	- changes to make it work as a loadable builtin compiled with gcc4

lib/readline/bind.c
	- add SYS_INPUTRC as last-ditch default (if DEFAULT_INPUTRC does not

lib/readline/doc/rluser.texi
	- add description of /etc/inputrc as ultimate default startup file

				   2/10
				   ----
lib/readline/bind.c
	- fix problem with rl_function_of_keyseq that returns a non-keymap
	  bound to a portion of the passed key sequence without processing
	  the entire thing.  We can bind maps with existing non-map
	  functions using the ANYOTHERKEY binding code.

variables.c
	- shells running in posix mode do not set $HOME, as POSIX apparently

lib/glob/sm_loop.c
	- change extmatch() to turn off FNM_PERIOD in flags passed to recursive

	  get multiple-free errors

				    3/5
				    ---
trap.c
	- inheritance of the DEBUG, RETURN, and ERR traps is now dependent
	  only on the `functrace' and `errtrace' shell options, as the
	  documentation says, rather than on whether or not the shell is in
	  debugging mode.  Reported by Philip Susi <psusi@cfl.rr.com>

parse.y
	- in parse_matched_pair, don't recursively parse ${...} or other

builtins/common.h
	- change extern declaration for get_directory_stack

variables.c
	- call get_directory_stack with an arg of 0 to inhibit converting

	  Problem reported by Pascal Terjan <pterjan@mandriva.com>
	- command_word_completion_function returns what it's passed as a

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

lib/readline/readline.h

lib/readline/input.c
	- in rl_getc, if read() returns an error other than EINTR (after the

	  converting return value to EOF if readline is reading a top-level
	  command (RL_STATE_READCMD)

lib/readline/readline.c
	- if rl_read_key returns READERR to readline_internal_char[loop],
	  abort as if it had read EOF on an empty line, without any conversion
	  to newline, which would cause a partial line to be executed.  This
	  fixes the bug reported by Mathieu Bonnet <mathieu.bonnet@nalkym.org>

	  it will always behave as a directory.  Fix from Eric Blake

lib/readline/histfile.c
	- Cygwin's mmap() works in recent versions, so don't #undef HAVE_MMAP.
	  Recommendation from Eric Blake

lib/readline/rlwinsize.h
	- make sure tcflow() is defined on SCO Unix.  Fix from William Bader

aclocal.m4
	- add check for localeconv to AM_INTL_SUBDIR macro

config.h.in
	- add HAVE_LOCALECONV

lib/sh/snprintf.c
	- add check for HAVE_LOCALECONV for GETLOCALEDATA macro

general.[ch]
	- first argument to legal_number is now `const char *'

lib/readline/{readline,rlprivate}.h
	- move rl_display_prompt declaration from rlprivate.h to readline.h

lib/readline/util.h
	- new function: rl_free(void *mem), for use by users of readline dlls
	  on Windows

lib/readline/readline.h
	- new extern declaration for rl_free

lib/readline/doc/rltech.texi
	- document rl_free and rl_display_prompt for use by application writers

				   11/15
				   -----
aclocal.m4
	- change tests for /dev/fd and /dev/stdin to use constructs of the form
	  (exec test ... ) instead of test ... to avoid bash's /dev/fd and
	  /dev/stdin emulation

				   11/16
				   -----
jobs.c
	- in delete_job, reset_current was being called before the job slot
	  was cleared -- moved after job_slots[job] was set to NULL.  Fixes
	  bug reported by Dan Jacobson <jidanni@jidanni.org>

				   11/19
				   -----
findcmd.c
	- when the checkhash option is set, fix the check for the hashed
	  pathname being an existing executable file.  Old code required a
	  hash table deletion and re-addition.  Bug reported by Linda
	  Walsh <bash@tlinx.org>

				   11/21
				   -----
subst.c
	- in pos_params, handle case of `start' == 0 by making the list of
	  positional parameters begin with $0
	- in parameter_brace_substring, increment `len' if start == 0, sicne
	  we will be adding $0 to the beginning of the list when we process it

doc/{bash.1,bashref.texi}
	- document new behavior of `0' offset when using substring expansion
	  with the positional parameters

support/shobj-conf
	- changes to shared object creation for loadable builtins on Mac OS X
	  10.4 to use libtool instead of ld by specifying -dynamiclib
	  argument and changing options to be appropriate for libtool.  This
	  winds up creating a dynamic shared library instead of an executable

				   11/24
				   -----
{jobs,nojobs}.c
	 - don't set last_asynchronous_pid to the child's pid in the child
	   for asynchronous jobs (for compatibility -- all other posix shells
	   seem to do it this way).  This means that (echo $! )& echo $! should
	   display two different pids.  Fix from discussion on the
	   austin-group-l list

builtins/mkbuiltins.c
	- change builtins.c file generation so short doc strings are marked for
	  gettext and available for subsequent translation.  Suggestion by
	  Benno Schulenberg <bensberg@justemail.net>

builtins/{bind,cd,hash,inlib,printf,pushd,test,times,ulimit}.def

{shell,subst}.c
	- fix a few strings that were not marked as translatable.  Fix from
	  Benno Schulenberg <bensberg@justemail.net>

lib/readline/misc.c
	- new function, _rl_revert_all_lines(void).  Goes through history,
	  reverting all entries to their initial state by undoing any undo
	  lists.

lib/readline/rlprivate.h
	- extern declaration for _rl_revert_all_lines

rldefs.h
	- add #undef HAVE_STRCOLL if STRCOLL_BROKEN is defined, prep to move
	  from config.h.in.  Problem reported by Valerly Ushakov
	  <uwe@ptc.spbu.ru>

				   11/25
				   -----
lib/readline/readline.c
	- call _rl_revert_all_lines from readline_internal_teardown if the

lib/sh/zmapfd.c
	- new file, implements zmapfd(), which takes a file and returns its
	  contents in a string

externs.h
	- extern declaration for zmapfd

				   11/29
				   -----
builtins/evalfile.c
	- in _evalfile, use zmapfd to read the contents of the file into a
	  string, rather than using the size reported by stat and reading that
	  many characters, if the file is not a regular file (for things like
	  named pipes, stat reports the size as 0)

				   12/3
				   ----
lib/sh/snprintf.c
	- make sure number() sets the FL_UNSIGNED flag for %x and %X, so
	  fmtulong treats them as unsigned numbers.  Fixes bug reported by
	  James Botte <James.M.Botte@lowes.com>

				   12/13
				   -----
lib/readline/util.c
	- new function, _rl_ttymsg, for internal warning messages -- does

	- new function, _rl_errmsg, for internal warning/error messages --
	  does not do redisplay after printing message

lib/readline/rlprivate.h
	- new extern declaration for _rl_ttymsg, _rl_errmsg

lib/readline/{bind,callback,complete,display,rltty}.c
	- use _rl_ttymsg/_rl_errmsg instead of direct writes to stderr

lib/sh/tmpfile.c
	- in get_tmpdir(), make sure that $TMPDIR names a writable directory;
	  otherwise skip it.  This catches names longer than PATH_MAX, but in
	  case it doesn't test that the length does not exceed PATH_MAX.  Fixes
	  heap overrun bug reported by Eric Blake <ebb9@byu.net>

builtin/{set,declare,shopt,trap,wait,bind,complete,enable,fc,history,read,setattr}.def
doc/{bash.1,bashref.texi}
	- improvements and clarifications to the help text associated with
	  several builtins, in some cases bringing them into line with the
	  man page text.  From Benno Schulenberg <bensberg@justemail.net>

doc/{bash.1,bashref.texi}
	- add `E' and `T' to the synopsis of the set builtin.

	  From Benno Schulenberg <bensberg@justemail.net>

				   12/19
				   -----
builtins/common.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
	  descriptions instead of 1
	- change to print in columns with entries sorted down rather than across
	  (that is, like `ls' rather than `ls -x').  Change inspired by Benno 
	  Schulenberg <bensberg@justemail.net>

jobs.h
	- give values to the JOB_STATE enumerations so they can be used as
	  bitmasks, too

				   12/22
				   -----
doc/{bash.1,bashref.texi}
	- change description of `set' to make it clearer that you can use
	  `+' to turn off options
	- clarify in the description of word splitting that sequences of
	  IFS whitespace at the beginning or end of the string are ignored

				   12/26
				   -----
doc/bashref.texi
	- move `shopt' builtin to its own section; change internal references
	  from `Bash Builtins' to the new shopt builtin
	- new section for builtins that modify shell behavior in `Shell
	  Builtin Commands'; move set and shopt to new section.  Changes
	  inspired by Benno Schulenberg <bensberg@justemail.net>

{redir,subst}.c
	- add MT_USETMPDIR flag to calls to sh_mktmpfd and sh_mktmpname.  Bug
	  reported by Eric Blake <ebb9@byu.net>

{configure,Makefile}.in
	- changes so that the pathname for DEBUGGER_START_FILE is substituted
	  into pathnames.h at make time (allowing more flexibility in setting
	  `prefix' or `datadir') instead of at configure time.  Suggested by
	  Nick Brown <nickbroon@blueyonder.co.uk>

shell.c
	- declaration for  have_devfd; initialized from HAVE_DEV_FD
	- declaration for check_jobs_at_exit; initialized to 0
	- declaration for autocd; initialized to 0

variables.c
	- new dynamic variable, BASHPID, always set from return value from
	  getpid() (changes even when $$ doesn't change).  Idea from Bruce
	  Korb <bruce.corb@3pardata.com>

builtins/exit.def
	- if check_jobs_at_exit is non-zero, list jobs if there are any stopped
	  or running background jobs; don't exit shell if any running jobs

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

builtins/shopt.def
	- new `checkjobs' option, changes value of check_jobs_at_exit
	- new `autocd' option, changes value of autocd

pcomplete.c
	- add COMP_TYPE, set to rl_completion_type, to list of variables set
	  by bind_compfunc_variables and unset by unbind_compfunc_variables

doc/{bash.1,bashref.texi}
	- document BASHPID

aclocal.m4
	- in BASH_SYS_SIGLIST, check HAVE_DECL_SYS_SIGLIST instead of the
	  obsolete and no-longer-supported SYS_SIGLIST_DECLARED

				   12/30
				   -----
lib/readline/vi_mode.c
	- 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
	- add variable rl_completion_invoking_key; allows applications to
	  discover the key that invoked rl_complete or rl_menu_complete

lib/readline/readline.h
	- extern declarations for rl_completion_invoking_key and
	  rl_sort_completion_matches

lib/readline/doc/rltech.texi
	- documented rl_completion_invoking_key and rl_sort_completion_matches

pcomplete.c
	- export variable COMP_KEY to completion functions; initialized from
	  rl_completion_invoking_key; unset along with rest of completion
	  variables

doc/{bash.1,bashref.texi},lib/readline/doc/rluser.texi
	- document COMP_KEY

[many files]
	- changes to make variables and function parameters `const' for better
	  text sharing.  Changes originally from Andreas Mohr
	  <andi@rhlx01.fht-esslingen.de>

				 1/4/2007
				 --------
lib/intl/Makefile.in
	- use cmp before copying libgnuintl.h to libintl.h -- maybe save a few
	  rebuilds

lib/builtins/Makefile
	- fixes to build LIBINTL_H if necessary, dependency on this for
	  mkbuiltins.o prevented `make -j 6' from working correctly

				    1/8

subst.c
	- new function, fifos_pending(), returns the count of FIFOs in
	  fifo_list (process substitution)

subst.h
	- extern declaration for fifos_pending()

execute_cmd.c
	- in execute_simple_command, if CMD_NO_FORK is set before we call
	  execute_disk_command, make sure there are no FIFOs in the expanded
	  words (from process substitution) and turn off CMD_NO_FORK if there
	  are, so they can get unlinked when the command finishes

				   1/10
				   ----
subst.c
	- read_comsub now takes a flags parameter and returns appropriate W_*
	  flags in it
	- command_substitute now returns a WORD_DESC *, with the string it used
	  to return as the `word' and `flags' filled in appropriately

subst.h
	- changed extern declaration for command_substitute

{pcomplete,subst}.c
	- changed callers of command_substitute appropriately

subst.c
	- string_extract_verbatim now takes an additional int flags argument;
	  changed callers

support/texi2html
	- fix problem that caused index links to not be generated if the first
	  index node had a name different than the node name

doc/bashref.texi
	- encapsulated all indexes into a single `Indexes' appendix; works
	  around bug fixed in texi2html

				   1/12
				   ----
subst.c
	- add call to sv_histtimefmt in initialize_variables so HISTTIMEFORMAT
	  from the environment is honored.  Fix from Ark Submedes (heh)
	  <archimerged@gmail.com>

lib/readline/histfile.c
	- 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
	  saved to and read from the history file

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
	  case of unquoted $@).  Corresponding changes to dequote_escapes.
	  Fixes a couple of problems reported by Brett Stahlman
	  <brettstahlman@comcast.net>

				   1/14
				   ----
subst.c
	- make same change to read_comsub to add CTLESC before ' ' if $IFS is
	  null, since we will split on literal spaces later

				   1/15
				   ----
array.c
	- new function, array_quote_escapes (ARRAY *a), calls quote_escapes
	  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

				   1/31

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
	- by default, if all else fails, set shell's idea of locale to ""
	  instead of its idea of `default_locale' -- the library functions
	  behave better with that value

				    2/2
				    ---
builtins/printf.def
	- if PRI_MACROS_BROKEN is defined, #undef PRIdMAX (AIX 4.3.3 broken)

				    2/3

Makefile.in,{builtins,doc}/Makefile.in,lib/*/Makefile.in
	- add assignment for datarootdir as per GNU coding standards

Makefile.in,builtins/Makefile.in,lib/intl/Makefile.in,po/Makefile.in.in
	- use @localedir@ instead of $(datadir)/locale in assignment

				   2/13

jobs.c
	- fix compact_jobs_list to not return js.j_lastj, since that is in use
	  and should not be overwritten.  Fix from Len Lattanzi
	  <llattanzi@apple.com>

				   2/16
				   ----
lib/readline/text.c
	- change rl_forward_char to allow moving to the end of the line when
	  using the arrow keys in vi insertion mode, rather than having the
	  behavior identical between vi command and insertion modes.  Change
	  suggested by Hugh Sasse <hgs@dmu.ac.uk>

CWRU/audit-patch

lib/readline/{complete,input,isearch,misc,readline,text,vi_mode}.c
	- make sure cases where rl_read_key returns -1 (usually due to EIO
	  because the controlling tty has gone away) are handled correctly.
	  Prompted by report from Thomas Loeber <ifp@loeber1.de>

				   3/10

sig.c
	- new function, top_level_cleanup, callable from contexts where some
	  cleanup needs to be performed before a non-fatal call to
	  jump_to_top_level

sig.h
	- new extern declaration for top_level_cleanup

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

				   3/13
				   ----
lib/readline/complete.c

				   ----
builtins/evalfile.c
	- make sure read() returns a value >= 0 before using it as an index
	  into string[]
	- use a variable of type `ssize_t' for return value from read()
	- only try to read the entire contents of a regular file in one shot
	  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>

parse.y
	- when adding at CTLESC character to the current token, do not
	  escape it with CTLESC if pass_next_character indicates that the
	  CTLESC was escaped by a backslash.  Fixes bug reported by
	  Paul Bagshaw <paul.bagshaw@orange-ftgroup.com>.

doc/Makefile.in

mailcheck.c
	- new function, init_mail_dates, calls remember_mail_dates only if
	  there are no mailboxes in `mailfiles'
	- new function, init_mail_file, initializes a FILEINFO, using the
	  last time mail was checked as the mtime and atime (or the time the
	  shell was started if last_time_mail_checked is uninitialized)
	- call init_mail_file instead of update_mail_file in add_mail_file,
	  called from remember_mail_dates (which is supposed to initialize
	  the list of mail files)
	- new convenience functions, alloc_mail_file and dispose_mail_file to

mailcheck.h
	- extern declaration for init_mail_dates

shell.c
	- call init_mail_dates instead of remember_mail_dates

				    4/5
				    ---
subst.c
	- make sure quote_escapes is only ever called when the word to be

				    4/6
				    ---
subst.c
	- change all EX_* defines to begin with SX_
	- 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
	  CTLNUL even if SX_NOCTLESC is set in the flags passed, to protect
	  the CTLNULs from future calls to remove_quoted_nulls.  Only
	  matters when $IFS contains CTLESC
	- changes to cope with $IFS containing CTLNUL in the same way as the

builtins/complete.def
	- make sure the `command' argument to the -C option is printed with

	  reported by martin@snowplow.org

execute_cmd.c
	- change execute_builtin_or_function and execute_subshell_builtin_or_function
	  to call fflush(stdout) after the builtin or function returns, to
	  make sure that all output  is flushed before the call returns.  It
	  matters on cygwin.  Fix suggested by Eric Blake <ebb9@byu.net>

redir.c
	- in do_redirection_internal, if the file descriptor being acted upon
	  is the same one used by the stdout stream, call fflush(stdout) to

	  an error on stdout.  Takes exit status as argument; returns new exit
	  status (EXECUTION_FAILURE if write error)

builtins/common.h
	- new extern declaration for sh_chkwrite

builtins/{alias,cd,complete,echo,fc,history,pushd,shopt,times,trap,type,ulimit,umask}.def
	- change to use sh_chkwrite to report write errors

builtins/fc.def
	- if an error occurs while writing commands from the history to a file
	  to be executed, report a write error and return failure without
	  attempting to execute any commands

lib/readline/input.c
	- fix off-by-one errors in _rl_get_char (pop_index) and rl_stuff_char
	  (push_index) that caused the 511th character in the buffer to be
	  discarded.  Fixes bug reported by Tom Bjorkholm <tom.bjorkholm@ericsson.com>

				    5/8
				    ---
subst.c
	- fix parameter_brace_remove_pattern to pass getpattern() newly-allocated
	  memory.  If word expansions (particularly brace expansions) are
	  required, the expansion code will free the string passed to
	  expand_word_internal, and we don't want to free unallocated memory
	  (patstr++) or have duplicate frees (patstr).  Fixes bug reported on
	  Red Hat bugzilla

lib/readline/signals.c

	  SIGTERM.  Bug reported by Ed Kwan <ed.kwan@onstor.com>

				   5/18
				   ----
jobs.c
	- change compact_jobs_list to return 1 if js.j_lastj == 0 and there is
	  a job in jobs[0]; compact_jobs_list should never return an index
	  already occupied
	- change reset_job_indices to avoid infinite looping when js.j_firstj
	  == 0 or js.j_firstj == js.j_jobslots upon function entry.  Fixes
	  bug reported by osicka@post.cz

execute_cmd.c
	- new variable, executing_builtin, keeps track of number of "levels"
	  of builtins being executed; incremented by execute_builtin; saved
	  and restored by execute_simple_command

subst.c
	- new variable, assigning_in_environment, set and unset around calls
	  to assign_in_env by the expansion code

variables.c
	- use executing_builtin and assigning_in_environment to decide whether
	  or not to look into temporary_env when calling find_variable_internal.

redir.c
	- 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'.
	  Fixes problem reported by Joseph Michaud <jmichaud@sgi.com>

				   5/24

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.

subst.c
	- remove_quoted_escapes is now global

print_cmd.c
	- in named_function_string, if FUNC_EXTERNAL is in the flags argument,
	  call remove_quoted_escapes to convert from internal to external form.
	  Fixes bug reported by Bo Andresen <bo.andresen@zlin.dk>

variables.c,builtins/{declare,setattr,type}.def

builtins/help.def
	- fix bug in `help' two-column printing to avoid referencing
	  shell_builtins[num_shell_builtins]

arrayfunc.c
	- change array_value_internal to set *RTYPE to 1 if the reference is
	  array[*] and 2 if the reference is array[@]

subst.c
	- in parameter_brace_expand_word, set the flags returned by the word
	  desc to include W_HASQUOTEDNULL if array_value returns QUOTED_NULL
	  for an array reference like x[*] and the word is quoted.  Fixes bug

	  fail, for subsequent error messages
	- change initialize_job_control to turn off job control if the terminal
	  pgrp == -1 or is not equal to shell_pgrp (with an error message)
	- in initialize_job_control, if the shell has been forced interactive
	  with -i, make sure stderr is hooked to a tty before using it as
	  the controlling terminal.  If it's not, try to open /dev/tty and

	- add POSIX_BUILTIN to the builtin flags if the builtin name is one
	  that's special to the posix command search order

builtins.h

	  the second line into account when calculating the number of
	  invisible characters on the current screen line
	- use WRAP_OFFSET where appropriate (update_line, _rl_move_cursor_relative)
	- change update_line to deal with adjusting _rl_last_c_pos in a
	  multibyte environment when the prompt has invisible chars on the
	  second line and redisplay has output the invisible characters
	- change _rl_move_cursor_relative to adjust _rl_last_c_pos in a

	  in the history list has not yet been deleted, since fc_gethnum
	  assumes that it has not.  Fix from John Haxby <john.haxby@oracle.com>

lib/readline/complete.c
	- new private library function, _rl_reset_completion_state(), used to
	  reset any completion state internal to the library when a signal

pcomplete.c
	- programmable_completions now saves pointer to the compspec it's
	  working with in new global variable CURCS
	- new function, pcomp_set_readline_variables, that sets or unsets
	  readline variables based on a passed flags value (COPT_FILENAMES,

	  Kratchovil <jan.kratchovil@redhat.com>

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>

builtins/common.h
	- new extern declaration for show_all_var_attributes

builtins/declare.def
	- change `declare -p' to print out all variable attributes and values,

builtins/set.def
	- use `enable_history_list' instead of `remember_on_history' to keep
	  value of `-o history' option

builtins/evalstring.c
	- instead of unwind-protecting remember_on_history, use a function to
	  restore it to the value of `enable_history_list' after
	  parse_and_execute runs the commands in the string.  This allows
	  history to be turned off in a startup file, for instance.  Problem
	  reported by Dan Jacobson <jidanni@jidanni.org>

				   4/11

bashline.c
	- limited support for completing command words with globbing characters
	  (only a single match completed on TAB, absolute or relative
	  pathnames supported, no $PATH searching, some support for displaying
	  possible matches, can be used with menu completion).
	  Suggested by Harald Koenig <h.koenig@science-computing.de>

builtins/fc.def
	- fixed a problem caused by change of 1/21 to use remember_on_history,
	  since it's turned off by parse_and_execute(), but can cause the
	  last command in history to be deleted and leave last_hist pointing
	  beyond the end of the history list.  edit_and_execute_command can
	  do this.

bashline.c
	- new define, RL_BOOLEAN_VAR_VALUE, to take a readline boolean variable
	  and get its value as 0 or 1 (consider making readline global)
	- put tty back into canonical mode before calling parse_and_execute in

	  prompt with invisible characters on the first and last lines, use
	  the number of inivisible chars on the first line in the calculation

	- new defines for new &>> r_append_err_and_out redirection

builtins/evalstring.c
	- new function, parse_string, parses a command from a passed string
	  and returns the number of characters consumed.  For satisfying
	  Posix rules when parsing command substitutions, from bash-4.0-devel
	  branch
	- split out common prolog code from parse_string and
	  parse_and_execute into a separate function called from both

parse.y
	- small changes to add symbols needed for parse_string
	- parser change to add `|&' as synonym for `2>&1 |'; translation is
	  performed at parse time so |& never shows up in output of
	  print_command, for instance.  Picked up from zsh, merged in from
	  bash-4.0-devel branch

parse.y,{redir,copy_cmd,dispose_cmd,make_cmd,print_cmd}.c
	- implement new &>> r_append_err_and_out (like >>foo 2>&1); merged
	  in from bash-4.0-devel branch

doc/{bash.1,bashref.texi},lib/readline/doc/rluser.texi
	- document new optional increment in brace expansion

	  appropriate

execute_cmd.c
	- implement new case clause action list terminators:
		;& - fall through to actions associated with next pattern list
		;;& - fall through to tests in next pattern list

doc/{bash.1,bashref.texi}

jobs.c
	- change waitchld so it treats SIGCHLD like SIGINT if `wait' is being
	  executed, and allows wait to jump out before running any trap set
	  on SIGCHLD.  Fixes debian bug #483016 reported by Miroslav Rudisin
	  <miero@atrey.karlin.mff.cuni.cz>
	- run_sigchld_trap is no longer static, so the trap code in trap.c
	  can call it
	- change run_sigchld_trap to call set_impossible_sigchld_trap instead
	  of just using a call to restore_default_signal

jobs.h
	- new extern declaration for run_sigchld_trap

trap.c
	- fix run_pending_traps to run a SIGCHLD trap if the trap handler isn't
	  set to IMPOSSIBLE_TRAP_HANDLER
	- in trap_handler, don't reset the SIGCHLD trap handler to trap_handler
	  if MUST_REINSTALL_SIGHANDLERS is defined
	- new function, set_impossible_sigchld_handler, sets the trap string
	  associated with SIGCHLD to IMPOSSIBLE_TRAP_HANDLER; used as a sentinel
	  by run_sigchld_trap and maybe_set_sigchld_handler
	- change maybe_set_sigchld_handler to set the SIGCHLD trap string only
	  if the current value is IMPOSSIBLE_TRAP_HANDLER.  This ensures that
	  any traps on SIGCHLD set in a SIGCHLD handler will persist.  Fixes
	  debian bug #483016 reported by Miroslav Rudisin

parse.y
	- new function: parse_comsub(), parses $(...) by parsing command
	  between parens and making sure the next token is `)'.  From
	  the bash-4.0-devel branch
	- new function: xparse_dolparen, helper function for parsing
	  command substitutions in $(...).  Called from subst.c to extract
	  a command substitution during word expansion.  From bash-4.0-devel
	  branch
	- new function: rewind_input_stream().  Rewinds bash_input.location.string
	  back to where it was before the shell parsed a $() command
	  substitution.  From bash-4.0-devel branch
	- changes to parse_matched_pair to combine most of the flag variables
	  (was_dollar, in_comment, and so on) into a local flags word

				    6/2

parse.y
	- call trim_pathname, which retains only the last $PROMPT_DIRTRIM

builtins/ulimit.def
	- make the multiplier (block size) for -c and -f 512 bytes only if in
	  Posix mode and 1024 bytes otherwise (as in previous versions).  Uses
	  POSIXBLK and BLOCK_SIZE defines to parameterize size based on value
	  of posixly_correct

doc/bashref.texi
	- document this addition to posix mode

builtins/common.c
	- change get_numeric_arg to have a calling sequence and return value
	  more closely mimicking general.c:legal_number(), with the addition
	  of a flags word
	- add extra value for `fatal' argument to get_numeric_arg to force it
	  to return failure to the caller rather than longjmping

builtins/common.h
	- change prototype declaration for get_numeric_arg

builtins/{break,shift}.def
	- change calls to get_numeric_arg to deal with new semantics and calling
	  sequence

builtins/history.def
	- display_history now returns an int
	- change calling sequence for get_numeric_arg in display_history
	- display_history now returns failure to the caller if get_numeric_arg
	  detects an invalid number, rather than jumping back to the top level
	- use value returned by display_history as return status of history
	  builtin, filtered through sh_chkwrite
	- history no longer aborts compound commands on invalid arguments.
	  fixes problem reported by Chu Li <chul@cn.fujitsu.com>

{braces,subst}.c
      - extract_command_subst now takes a third flags argument; passed flags
	are ORd into flags passed to other functions; changed callers

subst.h
	- move SX_* defines here from subst.c so parse.y:xparse_dolparen can
	  see them and behave appropriately
	- extract_command_subst now takes a third flags argument; change
	  prototype

subst.c
	- change extract_command_subst to call xparse_dolparen when extracting
	  a $() construct
	- change calls to extract_delimited_string to extract_command_subst
	  as appropriate
	- if command_substitute returns a NULL word desc, don't call
	  dispose_word_desc on it

parse.y
	- change xparse_dolparen to use the SX_* flags now in subst.h

	  dequote_string turns CTLNUL into ""
	- new function, string_list_pos_params, encapsulates everything
	  needed to turn the positional parameters or an array indexed with
	  '@' or '*' into a string, including taking care of quoting and
	  using the first char of $IFS, when used in another expansion like
	  pattern removal or pattern substitution

print_cmd.c
	- break code that prints here-documents into two functions:

	- 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

	  invisible variables, instead of assigning the null string to a
	  visible variable.  Fixes bug reported by Bernd Eggink <monoped@sudrala.de>

				   9/25
				   ----
builtins/common.[ch]
	- new function, builtin_warning(), like builtin_error but for warning
	  messages

builtins/bind.def
	- experimental: print a warning, but go on, if line editing not active
	  when bind is invoked.  Suggested by Rocky Bernstein
	  <rocky.bernstein@gmail.com>

				   10/3
				   ----
test.c
	- use same_file instead of directly comparing st_dev and st_ino when
	  comparing files in filecomp().  From mingw32 patches submitted
	  by Hector Chu <hkcc2@cantab.net>

				   10/4
				   ----

redir.c
	- in redirection_error(), use `error' instead of errno when comparing
	  against EBADF.  From mingw32 patches submitted by Hector Chu
	  <hkcc2@cantab.net>

shell.c
	- in unset_bash_input(), reset bash_input.type to st_none after
	  closing the default buffered fd.  From mingw32 patches submitted
	  by Hector Chu <hkcc2@cantab.net>

builtins/cd.def
	- ignore CDPATH when in privileged mode.  Suggested by Paul Jarc
	  <prj@po.cwru.edu>

variables.c
	- change sv_globignore to only act if privileged mode is not enabled.
	  Suggested by Paul Jarc <prj@po.cwru.edu>

doc/bash.1,bashref.texi
	- document new treatment of CDPATH and GLOBIGNORE when privileged
	  mode is enabled

builtins/read.def
	- change prompt printing to occur after terminal is set to no-echo
	  mode.  Based on suggestion from Stephane Chazelas
	  <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
	  _rl_susp_char
	- extern declaration for _rl_echoctl

lib/readline/readline.h
	- extern declaration for rl_echo_signal_char()

lib/readline/doc/rltech.texi
	- document rl_echo_signal_handler(): available for applications
	  that install their own signal handlers

execute_cmd.c
	- fix errexit logic to not cause the shell to exit when a command in
	  a pipeline fails.  Fixes bug reported by Marcin Owsiany
	  <marcin@owsiany.pl>

				   10/14
				   -----
builtins/evalstring.c
	- don't short-circuit execution in parse_and_execute if we want to
	  run an exit trap.  Fixes bug reported by Steffen Kiess
	  <s-kiess@web.de>

				   10/18
				   -----
parse.y
	- fix error production to only call YYACCEPT if the shell is currently
	  interactive and not in parse_and_execute (so parser errors in
	  things like eval will correctly set $?).  Fixes bug reported by
	  marco-oweber@gmx.de

execute_cmd.c
	- make sure variable name errors in execute_for_command and non-
	  identifier function names in execute_intern_function set the
	  return status to EX_BADUSAGE (2), not EX_USAGE (258)

parser.h
	- new parser state, PST_REPARSE

parse.y
	- turn PST_REPARSE on in parse_string_to_word_list
	- in parse_matched_pair, if parsing a single-quoted string and
	  PST_REPARSE is set, don't requote CTLESC or CTLNUL.  Fixes bug with
	  compound array assignment using $'\x7f' reported by Antonio Macchi
	  <antonio_macchi@alice.it>

				   10/23
				   -----
configure.in
	- define LOCAL_LDFLAGS as `-z interpose' on Solaris 8, 9, and 10 to
	  allow the bash malloc to interpose the libc malloc when called by
	  library functions pre-bound to the libc malloc.  Suggested by
	  Serge Dussud <Serge.Dussud@Sun.COM>

doc/bash.1
	- add single-sentence descriptions to rest of parameter expansions.
	  Suggested by Ken Irving <fnkci@uaf.edu>

				   10/27
				   -----
subst.c
	- rearrange code in skip_to_delims to allow quote characters and other
	  shell expansion characters to be delimiters
	- add new flags value for inverting search: skip to the next character
	  NOT in the set of delimiters passed as an argument

subst.h
	- define for new SD_INVERT flag value for skip_to_delims

				   10/28
				   -----
bashline.c
	- new bindable functions: shell-forward-word and shell-backward-word.
	  Like forward-word and backward-word, but understand shell quoting
	  and use shell metacharacters and whitespace as delimiters.
	  Suggested by Andre Majorel <amajorel@teaser.fr>
	- new bindable functions: shell-kill-word and shell-backward-kill-word.
	  Like kill-word and backward-kill-word, but understand shell quoting
	  and  use shell metacharacters and whitespace as delimiters.
	  Suggested by Andre Majorel <amajorel@teaser.fr>

doc/bash.1,lib/readline/doc/rluser.texi
	- documented shell-forward-word and shell-backward-word
	- documented shell-kill-word and shell-backward-kill-word

				   11/1
				   ----
redir.c
 	- add extra argument to add_undo_redirect: fdbase.  FD used to save
	  a file descriptor must be > fdbase if fdbase >= SHELL_FD_BASE.  A
	  value of -1 for fdbase means to just use SHELL_FD_BASE.  Fixes bug
	  with 0<&10 reported by Clark Jian Wang <dearvoid@gmail.com>

				   11/5
				   ----
unwind_prot.c
	- new function: have_unwind_protects(); returns 1 if unwind_protect_list
	  is not empty

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
	  if there's no unwind_protect_list, since there's a while loop in
	  throw_to_top_level that calls parse_and_execute_cleanup as long as
	  parse_and_execute_level is non-zero

				   11/9
				   ----
variables.c
	- fix the assign function for COMP_WORDBREAKS to allocate new memory
	  to store as the variable's value, to avoid freeing memory twice
	  if the variable is unset after rl_completer_word_break_characters
	  is freed and reallocated.  Fix from Mike Stroyan <mike@stroyan.net

				   11/11
				   -----
bashline.c
	- new function to reset the value of rl_completer_word_break_characters
	  while honoring setting of `hostcomplete': reset_completer_word_break_chars.

bashline.h
	- new extern declaration for reset_completer_word_break_chars.

variables.c
	- call reset_completer_word_break_chars in sv_comp_wordbreaks when the
	  variable is unset

[bash-4.0-beta frozen]

				   11/16
				   -----
subst.c
	- call set_pipestatus_from_exit in exp_jump_to_top_level so that
	  failed expansions that set $? will set $PIPESTATUS.  Fixes bug
	  reported by Eric Blake <ebb9@byu.net>

				   11/20
				   -----
general.c
	- new 'file_exists(fn)' primitive; just calls stat(2)

general.h
	- new extern declaration for file_exists

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
	  close-on-exec and use a flag (RX_SAVCLEXEC) to decide how to set
	  close-on-exec when the fd is restored.  Set flag in add_undo_redirect,
	  check in do_redirection_internal.  Fixes problem reported by Andreas
	  Schwab <schwab@suse.de>

				   11/26
				   -----
subst.c
	- fix param_expand to have expansions of $@ and $* exit the shell if
	  there are no positional parameters and `set -u' is enabled.  Fixes

				   11/27
				   -----
lib/readline/display.c
	- fix update_line to not call space_to_eol if current cursor position
	  (_rl_last_c_pos) indicates that we're already at end of line.
	  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).
	  Fix is in rl_redisplay.  part of fix for bug reported by
	  "Wesley J. Landaker" <wjl@icecavern.net> in
	  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=265182
	  [TENTATIVE]
	- fix _rl_move_cursor_relative to correctly offset `dpos' by `woff'
	  when there are invisible characters on lines after the second by
	  using (_rl_screenwidth*_rl_last_v_pos) when seeing whether or not
	  we just wrote some invisible characters.  Rest of fix for bug
	  reported in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=265182

				   -----
sig.c
	- reset the execution context before running the exit trap in
	  termsig_handler

general.c
	- set and unset terminate_immediately like interrupt_immediately in
	  bash_tilde_expand

builtins/read.def
	- change terminate_immediately to a counter instead of a flag, as
	  interrupt_immediately is used

lib/readline/display.c
	- slight change to fix from 11/27 to deal with prompts longer than a
	  screen line where the invisible characters all appear after the
	  line wrap.  Fixes bug reported by Andreas Schwab <schwab@suse.de>

builtins/{echo,printf}.def

doc/{bash.1,bashref.texi}
	- document more clearly that when not in Posix mode, command
	  substitution does not inherit the -e option.  From bug report from
	  Freddy Vulto <fvulto@gmail.com>

{execute_cmd,sig,builtins/evalstring}.c
	- sentinel variable to keep track of whether or not we're supposed to
	  ignore the failure status of a command executed in a command
	  substitution even if the `-e' option is set: comsub_ignore_return
	- increment and decrement comsub_ignore_return in execute_simple_command
	  before calling expand_words
	- in parse_and_execute, if comsub_ignore_return is non-zero and the
	  SUBSHELL_COMSUB bit is set in subshell_environment, enable the
	  CMD_IGNORE_RETURN flag in every command executed from the passed
	  string.  Fixes problem reported by Freddy Vulto <fvulto@gmail.com>
	- make sure to reset comsub_ignore_return every time we throw to the
	  top level, like executing_list flag
