changelog

android-w.song.android.widget

	- 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 [e-mail]

				   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 [e-mail]

				   12/10
				   -----
lib/readline/bind.c
	- make new-style "\M-x" keybindings obey `convert-meta' settings
	  (bug reported by [e-mail])

				   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
