i-bash/CWRU/changelog

				    6/2
				    ---
lib/readline/readline.c
	- fixed an off-by-one error in the kill ring reallocation code
	  in rl_kill_text

Makefile
	- replaced instances of /bin/sh with $(SHELL)

Makefile, cpp-Makefile, documentation/Makefile
	- added a working `uninstall' target

[1.14.0 FCS release made available for FTP]

				    6/3
				    ---
README
	- added note about building with gcc, same as in Makefile

documentation/Makefile
	- some versions of make don't understand `$*' in a regular recipe;
	  replace with features.dvi in the recipe for features.ps

				    6/4
				    ---
subst.c
	- fix up the calls to string_extract_double_quoted and 
	  string_extract_single_quoted in char_is_quoted so the initial
	  value of the index is *after* the opening quote character
	- make sure we only return 1 from char_is_quoted if the index
	  into the string after a call to string_extract_double_quoted or
	  string_extract_single_quoted is *greater than* `eindex'

lib/readline/complete.c
	- change the order and sense of the quoting tests in
	  rl_complete_internal so that the expensive char_is_quoted
	  is only called if `scan' actually is a word break character

shell.c
	- fixed a typo in the test for a restricted shell

builtins/exec.def
	- need to include flags.h

				    6/6
				    ---
make_cmd.c
	- make sure that we don't try to walk down a null command tree
	  in connect_async_list (tickled by `(command &) &')
	- if a command has the CMD_WANT_SUBSHELL bit set in its flags,
	  don't even try to walk the command tree and move the `&';
	  just connect the command with a null command using `&'

execute_cmd.c
	- make sure we don't try to reference a command struct without
	  first checking it (case '&')

				    6/7
				    ---
machines.h
	- fix a typo in the NeXT/i386 description; change the NeXT description
	  to #define HAVE_RESOURCE if not already defined rather than putting
	  -DHAVE_RESOURCE into the SYSDEP_CFLAGS

				    6/9
				    ---
Makefile
	- make sure all of the rules that reinvoke `make' have the
	  `-f bash-Makefile' before the assignment statements; some
	  versions of make like it that way

variables.c
	- make sure that `interactive' is set to 0 before evaluating the
	  string containing an exported function obtained from the
	  environment, so that it does not try to execute PROMPT_COMMAND
	  (this may not be the best fix)

				   6/13
				   ----
documentation/Makefile
	- make sure all of the directories exist before trying to install
	  doc files into them

lib/readline/history.c
	- add a missing O_TRUNC to the open call for writing in
	  history_truncate_file

trap.c
	- run_interrupt_trap should only try to run the trap command if
	  the value is not IMPOSSIBLE_TRAP_HANDLER

Makefile
	- add `realclean'

lib/readline/complete.c
	- do the same kind of double-quoting a replacement string if the
	  user supplies the opening double quote as we would if we were
	  adding both quotes ourselves

variables.c
	- fixed the variable initialization so that history_control/HISTCONTROL
	  can be inherited from a parent shell

INSTALL, README, cpp-Makefile, documentation/bash.1, documentation/readline.3
	- ai.mit.edu -> prep.ai.mit.edu

shell.c
	- fixed a problem with setting no_line_editing to the result of the
	  check for running inside emacs, thereby losing any value
	  initialized by the `-nolineediting' flag

cpp-Makefile
	- `make distclean' will now remove the `installed-bash' link

print_cmd.c
	- fixed a problem with undefined variables when HAVE_VARARGS_H is
	  not defined

				   6/14
				   ----
lib/readline/history.c
	- fixed an error in the csh history expansion code so that the
	  `-y' word designator now expands to `0-y' rather than `1-y'

lib/readline/isearch.c
	- changed an absolute check for a character falling within the
	  ASCII 32-126 range (printable chars) with checks for CTRL_P
	  and META_CHAR and a check against the value RUBOUT
	- changed a `break' to a `continue' so that the first non-matching
	  character in the search string does not cause the search to
	  end abruptly
	- initialize prev_line_found to 0 at the top of rl_search_history
	  to avoid duplicate history lines being saved across searches

lib/readline/rltty.c
	- consolidated repeated code for setting special characters into
	  `SET_SPECIAL' defines

lib/readline/readline.c
	- include <sys/ioctl.h> if VSTATUS is defined
	- add bindable command rl_tty_status (unbound by default)

lib/readline/funmap.c
	- assign bindable command name `tty-status' to rl_tty_status

INSTALL
	- add note about compiling with gcc, same text as README

lib/readline/display.c
	- many changes and tweaks to make redisplay work better when the
	  prompt has invisible characters.  These changes are non-optimal
	  in that the prompt is redrawn more than it needs to be, but
	  things are a hell of a lot better than they were

				   6/15
				   ----
documentation/Makefile
	- make a variable NROFF that people can set to `groff -Tascii' if
	  they don't have real nroff
	- changed the suffix rules to use $<

support/bashbug.sh
	- if rmail doesn't exist or fails, save the bug report in
	  ~/dead.bashbug

execute_cmd.c
	- in setup_async_signals, only ignore SIGINT and SIGQUIT if job
	  control is not active.  If it is active and the job is restarted,
	  SIGINT remains ignored, and the now-foregrounded job is not
	  interruptible

subst.c
	- fixed up a problem with char_is_quoted that caused backslash-
	  escaped characters to cause incorrect results

tests/run-dollars, tests/dollar-at.sh, tests/dollar-star.sh
	- since the error messages produced by `cat' vary, changed `cat'
	  to `recho' and updated the correct answers file

machines.h
	- fixes to CRAY_STACKSEG_END definitions for different versions of
	  Unicos on the YMP (from Bill Jones)
	- Motorola SVR4 machines have getcwd() and should not undef
	  HAVE_GETCWD
	- on hpux 9.x, don't try to link with -lPW if compiling with gcc
	  (for alloca)

parse.y
	- an ugly fix for a compiler problem with structure assignment on
	  the cray

				   6/16
				   ----
builtins/wait.def
	- replaced a call to sscanf with a validity check using all_digits()
	  and a call to atoi, since a pid_t is not necessarily an int, and
	  the sscanf clobbered the stack frame on systems where it is shorter
	  than an int (e.g., SCO)

lib/readline/display.c
	- since META_CHAR and the other macros only work with unsigned
	  chars, make rl_character_len convert its argument to an unsigned
	  char before testing it

documentation/Makefile
	- use $(INSTALL_DATA) instead of $(CP) to install the man pages and
	  info files

cpp-Makefile
	- use INSTALL_PROGRAM and INSTALL_DATA to install binaries and
	  documentation; pass both values to installs in subdirectories

				   6/18
				   ----
builtins/ulimit.def
	- compensate for systems which define RLIMIT_OFILE instead of
	  RLIMIT_NOFILE, or don't provide such a compatibility define
	  themselves

shell.c
	- make maybe_execute_file check for directories and print an
	  appropriate error message, since it's doing an fstat anyway

support/mksysdefs
	- added support for a `-s srcdir' option so it can find
	  cpp-Makefile if ansi-Makefile is to be created

Makefile
	- call mksysdefs with -s $(srcdir)

jobs.c
	- add the magic #undef lines to avoid redefinition warnings on
	  SunOS 4 only

				   6/20
				   ----
cpp-Makefile
	- install `bashbug' with `make install'

trap.c
	- make sure that `interactive' is set to 0 when running trap
	  commands

builtins/umask.c
	- fixed typo in usage error message

subst.c
	- fix process_substitute to set subshell_environment

jobs.c, nojobs.c
	- only mess with the terminal settings for an interactive shell
	  that is not in a subshell environment

				   6/21
				   ----
lib/readline/history.h
	- add extern declaration of history_get

builtins/fc.def
	- make history replacement when using `r' or `fc -s' obey the
	  setting of HISTCONTROL

general.c
	- in canonicalize_pathname, preserve a double // at the start
	  of an absolute pathname, since that means something special
	  for the network directory system

README, INSTALL
	- updated information about submitting bug reports

lib/readline/vi_mode.c, lib/readline/isearch.c
	- make sure unistd.h is included before rldefs.h, if
	  HAVE_UNISTD_H is defined

				   6/24
				   ----
lib/readline/complete.c
	- add `#' to the list of characters which cause a completed filename
	  to be quoted

execute_cmd.c
	- be more careful about closing pipe file descriptors in do_piping;
	  don't want to have `dup2(i, i); close(i);' problem

lib/readline/{keymaps,readline}.h
	- include local copies of include files if READLINE_LIBRARY is
	  defined, otherwise include the `official, installed' versions
	  using #include <readline/xxx.h>

lib/readline/*.c
	- define READLINE_LIBRARY before including any files
	- include only `local' copies of include files using #include "xxx.h"
	  rather than #include <readline/xxx.h>

				   6/26
				   ----
execute_cmd.c
	- check for clobbering the bash input stream before closing a file
	  descriptor due to an r_close_this redirection

lib/readline/history.c
	- made history_expand inhibit history expansion if the history
	  expansion char is set to 0

lib/readline/chardefs.h
	- moved savestring() definition to rldefs.h
	- changed lowercase_p, uppercase_p, to_lower, to_upper defines to
	  use <ctype.h> macros rather than assume ASCII

lib/readline/bind.c, general.c, general.h
	- use strcasecmp, strncasecmp instead of str[n]icmp if
	  HAVE_STRCASECMP is defined

cpp-Makefile
	- pass -DHAVE_STRCASECMP to builds in the libraries, primarily
	  readline

machines.h
	- add HAVE_STRCASECMP to the entries for BSD/386, NetBSD, FreeBSD,
	  and 4.4 BSD

builtins/hash.def
	- add a fourth parameter to remember_filename, the initial value
	  of times_found (0 if we're just looking it up for `hash', 1
	  for the command execution code)

execute_cmd.c
	- call remember_filename with an initial value of 1 for times_found

builtins/wait.def
	- handle a null argument with an error message

builtins/common.c
	- parse_and_execute now takes a third parameter: the value for
	  `interactive' while it is executing commands

bashline.c, jobs.c, parse.y, shell.c, subst.c, trap.c, variables.c
	- set the new third argument to parse_and_execute appropriately

builtins/eval.def, builtins/fc.def, builtins/source.def
	- set the new third argument to parse_and_execute appropriately

builtins/help.def
	- changed a call to strnicmp to strncmp when trying to find what
	  to give help on; it seems more correct

				   6/27
				   ----
machines.h
	- cleaned up the SunOS section so it no longer relies on
	  HAVE_SHARED_LIBS being defined; it uses SunOS4 and SunOS5
	  instead

support/mksysdefs
	- define SYSDEF to be SunOS4 or SunOS5 depending on the output
	  of uname rather than looking for ld.so

				   6/29
				   ----
machines.h
	- minor change to the ardent titan machine description
	- move the ardent and stardent descriptions before the
	  mips riscos description

print_cmd.c
	- ardent machines also need the extern declaration for printf

make_cmd.c
	- connect_async_list should do its work only if the lists to be
	  backgrounded are connected with `;'.  This makes `;' bind tighter
	  than `&', so only the last job in the list is backgrounded.  All
	  other lists should have the entire thing put in the background

parse.y
	- added a function `print_prompt' to take care of displaying the
	  prompt string if readline is not being used.  This fixes problems
	  with the prompt being displayed before the status of completed
	  jobs is printed

				   6/30
				   ----
builtins/fg_bg.def
	- `fg' and `bg' now print error messages if invoked when job control
	  is disabled

lib/readline/rltty.c
	- if not compiled into the shell, make get_tty_settings get and set
	  the window size.  This noop stops the process if it is started in
	  the background

lib/readline/readline.c
	- provide a function version of savestring, if not being compiled
	  into the shell, since the macro has been removed from the
	  `public' header files

lib/readline/readline.h
	- provide all extern function declarations without checking whether
	  VI_MODE or PAREN_MATCHING are defined.  It does not hurt to define
	  them if they are not used and not in the library, and other
	  applications using readline can't tell whether or not VI_MODE was
	  defined when the library was compiled anyway

				    7/1
				    ---
machines.h
	- add #undef HAVE_DIRENT_H to the ardent titan description

				    7/2
				    ---
lib/readline/chardefs.h
	- removed META_P define, renamed CTRL_P to CTRL_CHAR

lib/readline/bind.c, lib/readline/isearch.c
	- changed instances of CTRL_P to CTRL_CHAR

lib/readline/search.c
	- include <unistd.h> before rldefs.h, if HAVE_UNISTD_H is defined

lib/readline/readline.c
	- declare PC, UP, and BC as extern rather than `local' to the
	  readline library

				    7/5
				    ---
bashline.c
	- implement command word completion inside of command substitution
	  with a new function: `command_subst_completion_function'

subst.c
	- new function to help with command subst completion: unclosed_pair

lib/readline/complete.c
	- new variable rl_filename_quoting_desired, which can be set to 0
	  to inhibit the quoting of filenames after completion

lib/readline/readline.h
	- declare rl_filename_completion_desired and
	  rl_filename_quoting_desired

builtins/bind.def
	- don't save the old value of rl_outstream before initializing
	  readline -- it saves garbage values and screws up readline

parse.y
	- don't have private state telling whether or not readline has
	  been initialized -- use bash_readline_initialized like other
	  functions in bashline.c

lib/readline/readline.c
	- make the default 8-bit behavior be based on whether LC_CTYPE is
	  defined and its value (accept iso-8859-1 or iso_8859_1)

				    7/6
				    ---
variables.c
	- fix up the declaration of getenv() for convex machines

				    7/7
				    ---
lib/readline/readline.c
	- fixed up typos in the declaration of `savestring'

lib/readline/history.c
	- fixed an off-by-one error in the ADD_CHAR macro which caused one
	  extra character to be overwritten, causing the gnu malloc to abort
	  when that one character was at the end of an allocated block
	- changed the ADD_STRING macro to avoid some unnecessary xreallocs

lib/readline/display.c
	- fixed a problem with move_cursor_relative -- function now returns
	  immediately if it has nothing to do
	- fixed another problem with displaying prompts with invisible chars

lib/readline/chardefs.h
	- fixed the CTRL macro to be right (agree with the BSD kernel, for
	  example)

cpp-Makefile
	- fixed typo in the `install' recipe

				    7/8
				    ---
support/srcdir
	- fixed to handle srcdir when it begins with ./ or ../ to handle
	  $(srcdir) being a relative path better

cpp-Makefile
	- changed some include paths to $(BUILTIN_ABSSRC) when building in
	  `builtins' to handle $(srcdir) being a relative path
	- change the `chmod' on bashbug to turn on read and execute for all
	- added a couple of definitions to make it easier for a later
	  `configure' program

support/mksysdefs
	- added a -i option to specify an alternate set of directories to
	  search for include files

lib/readline/bind.c
	- in rl_read_init_file, when skipping whitespace at the start of
	  the line, decrement `i' so that we don't jump past the start
	  of the next line

machines.h
	- SCOv4 has a `robust' opendir that checks that you're actually
	  opening a directory

				   7/11
				   ----
lib/readline/complete.c
	- make sure a word break character is unquoted before using it to
	  separate out the current word for completing

machines.h
	- new machine description: NetBSD on motorola m68k machines like
	  the hp300
	- undef HAVE_GETWD in the generic svr4 machine description, like
	  other svr4 descriptions

lib/readline/rltty.c
	- make sure to fflush (rl_outstream) after toggling the setting
	  of the keypad and meta key

portbash/libc.sh
	- add a test for OPENDIR_NOT_ROBUST

support/getcppsyms.c
	- output __svr4__ if we find __uxps__ (this makes the Fujitsu port of
	  SVR4 to the sparc build OK)

				   7/12
				   ----
lib/readline/display.c
	- more display-related fixes when the prompt has invisible chars;
	  this time for screen updates when moving between screen lines

lib/readline/readline.c, lib/readline/display.c
	- changes to make readline work with terminals that have auto-wrap
	  from Per Bothner (new function _rl_update_final, term_xn changes,
	  some efficiency speedups, new function space_to_eol)

				   7/13
				   ----
lib/readline/display.c
	- after moving up screen lines using term_up in _rl_move_vert, if
	  the new screen line is 0, _rl_last_c_pos needs to be adjusted
	  to take invisible characters into account.  This was the source
	  of many bugs

				   
				   7/14
				   ----
documentation/Makefile
	- change instances of `groff' to `${GROFF}', GROFF is set to
	  `groff' by default

general.c, variables.c
	- moved `qsort_string_compare' from variables.c to general.c

general.h, variables.h
	- moved declaration of `qsort_string_compare' from variables.h
	  to general.h

alias.c, lib/readline/funmap.c
	- moved qsort auxiliary functions after their use and added
	  forward declarations to avoid warnings from ANSI C compilers

memalloc.h
	- hpux_9 needs alloca declared as `extern void *' if __STDC__
	  is defined

support/mksysdefs
	- removed HAVE_SHARED_LIBS entirely
	- make a call to /bin/uname -X for SCO machines to avoid running
	  a different uname from the $PATH

machines.h
	- new descriptions: Intel i860 running SVR4, Tahoe running 4.3 BSD
	- changed descriptions: Mips/RiscOS, DG AViiON, unknown machine

jobs.c
	- changes to how the shell handles foreground jobs dying of SIGINT:
		an interactive shell using job control will no longer
		act as if it received a SIGINT if the foreground job
		dies from a SIGINT

		a non-interactive shell or shell without job control tries
		to differentiate between SIGINTs it has seen (in
		wait_sigint_handler) and a foreground job dying of a SIGINT
		not sent from the keyboard, and runs the normal SIGINT code
		only in the former case

				   7/15
				   ----
support/mksysdefs
	- check for ${UNAME}${RELEASE} expanding to `SunOS4*' or `SunOS5*'
	  to set SYSDEF to SunOS4 or SunOS5, respectively.  Apparently
	  this does not work for Solbourne

				   7/18
				   ----

lib/readline/rltty.c
	- if output is being flushed on termios systems, loop until the
	  FLUSHO bit is no longer set in the termios struct

support/mksysdefs
	- added a -A flag to force creation of ansi-Makefile

machines.h
	- new entry for Tandem machines running SVR3

				   7/19
				   ----
lib/readline/rldefs.h
	- include <termcap.h> if HAVE_TERMCAP_H is defined
	- use <termio.h> stuff if HAVE_TERMIO_H is defined and _POSIX_VERSION
	  is not defined

lib/readline/rldefs.h, lib/readline/history.c
	- include "config.h" if HAVE_CONFIG_H is defined

lib/readline/{rldefs.h,signals.c,readline.c}
	- WINSIZE_IN_IOCTL_H -> GWINSZ_IN_SYS_IOCTL for compatibility with
	  other GNU programs

lib/readline/doc/Makefile
	- fixed up to create the readline and history manuals in dvi and
	  ps format

lib/readline/Makefile
	- changes inspired by the standalone readline-2.0 distribution

				   7/20
				   ----
lib/readline/history.c
	- new function, history_is_stifled (), returns history_stifled
	- set history_state flags member in the history state functions

lib/readline/history.h
	- reorganized the function declarations, added missing declarations
	- history_stifled is no longer exported by the library
	- added a `flags' member to the HISTORY_STATE structure

bashline.c
	- use history_is_stifled () instead of history_stifled

lib/readline/readline.c, lib/readline/vi_mode.c
	- filled in correct argument declarations for functions called via
	  keymaps (count, key)

lib/readline/complete.c
	- efficiency improvement for compare_strings

				   7/21
				   ----
examples/dirfuncs
	- new directory functions from ksh book, contributed by
	  Ken Konecki (kenk@wfg.com)

machines.h
	- hpux_8 and hpux_9 should both #undef HAVE_ALLOCA unless gcc is
	  being used

				   7/22
				   ----
bashline.c
	- fixed up command_word_completion_function so that filenames with
	  leading tildes are completed correctly

				   7/26
				   ----
builtins/read.def
	- if -r not given, make sure CTLESC is removed from input string
	  when reading \<newline>

lib/readline/readline.c
	- new function bind_arrow_keys, which binds vt100/ansi arrow key
	  escape sequences after reading the termcap definition and the
	  inputrc file
	- new function rl_yank_last_arg, which does what insert-last-arg
	  does in bash

lib/readline/emacs_keymap.c
	- remove default bindings to rl_arrow_keys for M-[ and M-O
	- rl_yank_last_arg is now bound to `M-.' and `M-_' in
	  emacs_meta_keymap

subst.c
	- when performing process substitution on systems with /dev/fd,
	  make sure the child clears the slot in dev_fd_list it gets
	  from its parent so the file descriptor does not get closed
	  inappropriately if reallocated by, e.g., pipe(2)

bashline.c
	- removed insert_last_arg and the calls to bind in to `M-.' and `M-_'.
	  `insert-last-argument' is now bound to rl_yank_last_arg for
	  backwards compatibility

lib/readline/funmap.c
	- `yank-last-arg' is now a named command for rl_yank_last_arg


documentation/bash.1, documentation/readline.3
	- add description of yank-last-arg as one of the readline user
	  commands

lib/readline/doc/rluser.texinfo
	- added description of yank-last-arg

builtins/getopts.def
	- fixed a typo in the int-to-string code computing the value to set
	  OPTIND to: had '\0' instead of '0'
	- made getopts handle the case where there are more than 9 dollar
	  variables (where rest_of_args is non-null) correctly

				   7/28
				   ----
lib/readline/display.c
	- fixes to the display code for single-line-display in the presence
	  of prompts containing invisible characters

lib/readline/readline.c
	- if we are using horizontal scrolling and we have term_xn, decrement
	  the screenwidth by 1, since we won't be doing any line wrapping

				   7/31
				   ----
jobs.c
	- new variable `freeze_jobs_list' to set when changes to the jobs
	  list or status of jobs in the list (other than calling something
	  like `jobs -n') are undesirable.  This is set when execuing traps
	  on SIGCHLD

				    8/1
				    ---
subst.c
	- check that `~' is unquoted before performing tilde expansion in
	  an assignment statement

				    8/3
				    ---
bracecomp.c
	- keep brace completion from dumping core if there is only one
	  match

lib/readline/chardefs.h
	- add a define for digit_p, which returns the value of isdigit()

lib/readline/readline.c
	- added function equivalents for uppercase_p, lowercase_p, to_upper,
	  to_lower, pure_alphabetic, digit_p, and digit_value
	- replaced calls to numeric () with calls to digit_p, removed
	  definition of numeric ()

lib/readline/history.c
	- digit -> digit_p

lib/readline/vi_mode.c
	- replaced uses of the `isletter' define to use pure_alphabetic
	  from chartypes.h
	- replaced uses of `numeric' with calls to digit_p
	- added do...while(0) to `exchange' define

				    
				    8/4
				    ---
execute_cmd.c
	- make sure execute_function saves and restores the current loop
	  count with unwind_protect_int

documentation/features.texi
	- change the `Shell Command Line Options' section to `Invoking
	  Bash' to be closer to the GNU coding standards

				    8/5
				    ---
builtins/read.def
	- fixed up a memory leak and made behavior correct when no
	  variables given and backslash escaped at least one input char
	- if we added CTLESC anywhere while reading the input string,
	  make sure we call dequote_string on each word of the input
	  before calling bind_variable with that string
