				 7/27/2004
				 ---------

[bash-3.0 released]

				   7/28
				   ----
array.c
	- in array_insert(), make sure the value to be added is non-NULL before
	  calling savestring() on it

builtins/reserved.def
	- fix description of `CDPATH'

lib/readline/display.c
	- when expanding a prompt that spans multiple lines with embedded
	  newlines, set prompt_physical_chars from the portion after the
	  final newline, not the preceding portion.  Bug reported by
	  "Ralf S. Engelschall" <[e-mail]>

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 [e-mail]

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 <[e-mail]>

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 [e-mail] 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
