This document details the changes between this version, bash-3.2-release,
and the previous version, bash-3.2-beta.
1. Changes to Bash
a. Fixed a bug that caused the temporary environment passed to a command to
affect the shell's environment under certain circumstances.
b. Fixed a bug in the printf builtin that caused the %q format specifier to
ignore empty string arguments.
c. Improved multibyte character environment detection at configuration time.
d. Fixed a bug in the read builtin that left spurious escape characters in the
input after processing backslashes when assigning to an array variable.
2. Changes to Readline
a. Fixed a redisplay bug that occurred in multibyte-capable locales when the
prompt was one character longer than the screen width.
------------------------------------------------------------------------------
This document details the changes between this version, bash-3.2-beta,
and the previous version, bash-3.2-alpha.
1. Changes to Bash
a. Changed the lexical analyzer to treat locale-specific blank characters as
white space.
b. Fixed a bug in command printing to avoid confusion between redirections and
process substitution.
c. Fixed problems with cross-compiling originating from inherited environment
variables.
d. Added write error reporting to printf builtin.
e. Fixed a bug in the variable expansion code that could cause a core dump in
a multi-byte locale.
f. Fixed a bug that caused substring expansion of a null string to return
incorrect results.
g. BASH_COMMAND now retains its previous value while executing commands as the
result of a trap, as the documentation states.
2. Changes to Readline
a. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
the prompt and input line multiple times.
b. Fixed history expansion to not be confused by here-string redirection.
c. Readline no longer treats read errors by converting them to newlines, as
it does with EOF. This caused partial lines to be returned from readline().
------------------------------------------------------------------------------
This document details the changes between this version, bash-3.2-alpha,
and the previous version, bash-3.1-release.
1. Changes to Bash
a. Fixed a source bug that caused the minimal configuration to not compile.
b. Fixed memory leaks in error handling for the `read' builtin.
c. Changed the [[ and (( compound commands to set PIPESTATUS with their exit
status.
d. Fixed some parsing problems with compound array assignments.
e. Added additional configuration changes for: NetBSD (incomplete multibyte
character support)
f. Fixed two bugs with local array variable creation when shadowing a variable
of the same name from a previous context.
g. Fixed the `read' builtin to restore the correct set of completion functions
if a timeout occurs.
h. Added code to defer the initialization of HISTSIZE (and its stifling of the
history list) until the history file is loaded, allowing a startup file to
override the default value.
i. Tightened up the arithmetic expression parsing to produce better error
messages when presented with invalid operators.
j. Fixed the cross-compilation support to build the signal list at shell
invocation rather than compile time if cross-compiling.
k. Fixed multibyte support for non-gcc compilers (or compilers that do not
allow automatic array variable sizing based on a non-constant value).
l. Several fixes to the code that manages the list of terminated jobs and
their exit statuses, and the list of active and recently-terminated jobs
to avoid pid aliasing/wraparound and allocation errors.
m. Fixed a problem that allowed scripts to die due to SIGINT while waiting
for children, even when started in the background or otherwise ignoring
SIGINT.
n. Fixed a bug that caused shells invoked as -/bin/bash from not being
recognized as login shells.
o. Fixed a problem that caused shells in the background to give the terminal
to a process group other than the foreground shell process group.
p. Fixed a problem with extracting the `varname' in ${#varname}.
q. Fixed the code that handles SIGQUIT to not exit immediately -- thereby
calling functions that may not be called in a signal handler context --
but set a flag and exit afterward (like SIGINT).
r. Changed the brace expansion code to skip over braces that don't begin a
valid matched brace expansion construct.
s. Fixed `typeset' and `declare' to not require that their shell function
operands to be valid shell identifiers.
t. Changed `test' to use access(2) with a temporary uid/euid swap when testing
file attributes and running setuid, and access(2) in most other cases.
u. Changed completion code to not attempt command name completion on a line
consisting solely of whitespace when no_empty_command_completion is set.
v. The `hash' builtin now prints nothing in posix mode when the hash table is
empty, and prints a message to that effect to stdout instead of stderr
when not in posix mode.
w. Fixed a bug in the extended pattern matching code that caused it to fail to
match periods with certain patterns.
x. Fixed a bug that caused the shell to dump core when performing filename
generation in directories with thousands of files.
y. Returned to the original Bourne shell rules for parsing ``: no recursive
parsing of embedded quoted strings or ${...} constructs.
z. The inheritence of the DEBUG, RETURN, and ERR traps is now dependent only
on the settings of the `functrace' and `errtrace' shell options, rather
than whether or not the shell is in debugging mode.
aa. Fixed a problem with $HOME being converted to ~ in the expansion of
members of the DIRSTACK array.
bb. Fixed a problem with quoted arguments to arithmetic expansions in certain
constructs.
cc. The command word completion code now no longer returns matching directories
while searching $PATH.
dd. Fixed a bug with zero-padding and precision handling in snprintf()
replacement.
ee. Fixed a bug that caused the command substitution code not to take embedded
shell comments into account.
ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an
arithmetic substitution.
gg. Fixed a bug in the prompt expansion code that inappropriately added a
\001 before a \002 under certain circumstances.
hh. Fixed a bug that caused `unset LANG' to not properly reset the locale
(previous versions would set the locale back to what it was when bash
was started rather than the system's "native" locale).
ii. Fixed a bug that could cause file descriptors > 10 to not be closed even
when closed explicitly by a script.
jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting
inside double-quoted command substitutions.
kk. Fixed a bug that could cause core dumps when `return' was executed as the
last element of a pipeline inside a shell function.
ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in
the jobs list.
2. Changes to Readline
a. Fixed a problem that caused segmentation faults when using readline in
callback mode and typing consecutive DEL characters on an empty line.
b. Fixed several redisplay problems with multibyte characters, all having to
do with the different code paths and variable meanings between single-byte
and multibyte character redisplay.
c. Fixed a problem with key sequence translation when presented with the
sequence \M-\C-x.
d. Fixed a problem that prevented the `a' command in vi mode from being
undone and redone properly.
e. Fixed a problem that prevented empty inserts in vi mode from being undone
properly.
f. Fixed a problem that caused readline to initialize with an incorrect idea
of whether or not the terminal can autowrap.
g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
convert-meta and use \e where appropriate.
h. Changed the default filename completion function to call the filename
dequoting function if the directory completion hook isn't set. This means
that any directory completion hooks need to dequote the directory name,
since application-specific hooks need to know how the word was quoted,
even if no other changes are made.
i. Fixed a bug with creating the prompt for a non-interactive search string
when there are non-printing characters in the primary prompt.
j. Fixed a bug that caused prompts with invisible characters to be redrawn
multiple times in a multibyte locale.
k. Fixed a bug that could cause the key sequence scanning code to return the
wrong function.
l. Fixed a problem with the callback interface that caused it to fail when
using multi-character keyboard macros.
m. Fixed a bug that could cause a core dump when an edited history entry was
re-executed under certain conditions.
n. Fixed a bug that caused readline to reference freed memory when attmpting
to display a portion of the prompt.
3. New Features in Bash
a. Changed the parameter pattern replacement functions to not anchor the
pattern at the beginning of the string if doing global replacement - that
combination doesn't make any sense.
b. When running in `word expansion only' mode (--wordexp option), inhibit
process substitution.
c. Loadable builtins now work on MacOS X 10.[34].
d. Shells running in posix mode no longer set $HOME, as POSIX requires.
e. The code that checks for binary files being executed as shell scripts now
checks only for NUL rather than any non-printing character.
f. Quoting the string argument to the [[ command's =~ operator now forces
string matching, as with the other pattern-matching operators.
4. New Features in Readline
a. Calling applications can now set the keyboard timeout to 0, allowing
poll-like behavior.
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
the default last-ditch startup file.
c. The history file reading functions now allow windows-like \r\n line
terminators.

30. Beginning with bash-3.1, the combination of posix mode and enabling the

31. Beginning with bash-3.2, bash follows the Bourne-shell-style (and POSIX-
style) rules for parsing the contents of old-style backquoted command
substitutions. Previous versions of bash attempted to recursively parse
embedded quoted strings and shell constructs; bash-3.2 uses strict POSIX
rules to find the closing backquote and simply passes the contents of the
command substitution to a subshell for parsing and execution.
32. Beginning with bash-3.2, bash uses access(2) when executing primaries for
the test builtin and the [[ compound command, rather than looking at the
file permission bits obtained with stat(2). This obeys restrictions of
the file system (e.g., read-only or noexec mounts) not available via stat.

the current setting of the `convert-meta' variable.

Notes on the Free Translation Project
*************************************
Free software is going international! The Free Translation Project
is a way to get maintainers of free software, translators, and users all
together, so that will gradually become able to speak many languages.
A few packages already provide translations for their messages.
If you found this `ABOUT-NLS' file inside a distribution, you may
assume that the distributed package does use GNU `gettext' internally,
itself available at your nearest GNU archive site. But you do _not_
need to install GNU `gettext' prior to configuring, installing or using
this package with messages translated.
Installers will find here some useful hints. These notes also
explain how users should proceed for getting the programs to use the
available translations. They tell how people wanting to contribute and
work at translations should contact the appropriate team.
When reporting bugs in the `intl/' directory or bugs which may be
related to internationalization, you should tell about the version of
`gettext' which is used. The information can be found in the
`intl/VERSION' file, in internationalized packages.
Quick configuration advice
==========================
If you want to exploit the full power of internationalization, you
should configure it using
./configure --with-included-gettext
to force usage of internationalizing routines provided within this
package, despite the existence of internationalizing capabilities in the
operating system where this package is being installed. So far, only
the `gettext' implementation in the GNU C library version 2 provides as
many features (such as locale alias, message inheritance, automatic
charset conversion or plural form handling) as the implementation here.
It is also not possible to offer this additional functionality on top
of a `catgets' implementation. Future versions of GNU `gettext' will
very likely convey even more functionality. So it might be a good idea
to change to GNU `gettext' as soon as possible.
So you need _not_ provide this option if you are using GNU libc 2 or
you have installed a recent copy of the GNU gettext package with the
included `libintl'.
INSTALL Matters
===============
Some packages are "localizable" when properly installed; the
programs they contain can be made to speak your own native language.
Most such packages use GNU `gettext'. Other packages have their own
ways to internationalization, predating GNU `gettext'.
By default, this package will be installed to allow translation of
messages. It will automatically detect whether the system already
provides the GNU `gettext' functions. If not, the GNU `gettext' own
library will be used. This library is wholly contained within this
package, usually in the `intl/' subdirectory, so prior installation of
the GNU `gettext' package is _not_ required. Installers may use
special options at configuration time for changing the default
behaviour. The commands:
./configure --with-included-gettext
./configure --disable-nls
will respectively bypass any pre-existing `gettext' to use the
internationalizing routines provided within this package, or else,
_totally_ disable translation of messages.
When you already have GNU `gettext' installed on your system and run
configure without an option for your new package, `configure' will
probably detect the previously built and installed `libintl.a' file and
will decide to use this. This might be not what is desirable. You
should use the more recent version of the GNU `gettext' library. I.e.
if the file `intl/VERSION' shows that the library which comes with this
package is more recent, you should use
./configure --with-included-gettext
to prevent auto-detection.
The configuration process will not test for the `catgets' function
and therefore it will not be used. The reason is that even an
emulation of `gettext' on top of `catgets' could not provide all the
extensions of the GNU `gettext' library.
Internationalized packages have usually many `po/LL.po' files, where
LL gives an ISO 639 two-letter code identifying the language. Unless
translations have been forbidden at `configure' time by using the
`--disable-nls' switch, all available translations are installed
together with the package. However, the environment variable `LINGUAS'
may be set, prior to configuration, to limit the installed set.
`LINGUAS' should then contain a space separated list of two-letter
codes, stating which languages are allowed.
Using This Package
==================
As a user, if your language has been installed for this package, you
only have to set the `LANG' environment variable to the appropriate
`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
and `CC' is an ISO 3166 two-letter country code. For example, let's
suppose that you speak German and live in Germany. At the shell
prompt, merely execute `setenv LANG de_DE' (in `csh'),
`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
This can be done from your `.login' or `.profile' file, once and for
all.
You might think that the country code specification is redundant.
But in fact, some languages have dialects in different countries. For
example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
country code serves to distinguish the dialects.
The locale naming convention of `LL_CC', with `LL' denoting the
language and `CC' denoting the country, is the one use on systems based
on GNU libc. On other systems, some variations of this scheme are
used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
locales supported by your system for your country by running the command
`locale -a | grep '^LL''.
Not all programs have translations for all languages. By default, an
English message is shown in place of a nonexistent translation. If you
understand other languages, you can set up a priority list of languages.
This is done through a different environment variable, called
`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
for the purpose of message handling, but you still need to have `LANG'
set to the primary language; this is required by other parts of the
system libraries. For example, some Swedish users who would rather
read translations in German than English for when Swedish is not
available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
In the `LANGUAGE' environment variable, but not in the `LANG'
environment variable, `LL_CC' combinations can be abbreviated as `LL'
to denote the language's main dialect. For example, `de' is equivalent
to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
(Portuguese as spoken in Portugal) in this context.
Translating Teams
=================
For the Free Translation Project to be a success, we need interested
people who like their own language and write it well, and who are also
able to synergize with other translators speaking the same language.
Each translation team has its own mailing list. The up-to-date list of
teams can be found at the Free Translation Project's homepage,
`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
area.
If you'd like to volunteer to _work_ at translating messages, you
should become a member of the translating team for your own language.
The subscribing address is _not_ the same as the list itself, it has
`-request' appended. For example, speakers of Swedish can send a
message to `sv-request@li.org', having this message body:
subscribe
Keep in mind that team members are expected to participate
_actively_ in translations, or at solving translational difficulties,
rather than merely lurking around. If your team does not exist yet and
you want to start one, or if you are unsure about what to do or how to
get started, please write to `translation@iro.umontreal.ca' to reach the
coordinator for all translator teams.
The English team is special. It works at improving and uniformizing
the terminology in use. Proven linguistic skill are praised more than
programming skill, here.
Available Packages
==================
Languages are not equally supported in all packages. The following
matrix shows the current state of internationalization, as of May 2003.
The matrix shows, in regard of each package, for which languages PO
files have been submitted to translation coordination, with a
translation percentage of at least 50%.

Some counters in the preceding matrix are higher than the number of
visible blocks let us expect. This is because a few extra PO files are
used for implementing regional variants of languages, or language
dialects.
For a PO file in the matrix above to be effective, the package to
which it applies should also have been internationalized and
distributed as such by its maintainer. There might be an observable
lag between the mere existence a PO file and its wide availability in a
distribution.
If May 2003 seems to be old, you may fetch a more recent copy of
this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date
matrix with full percentage details can be found at
`http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'.
Using `gettext' in new packages
===============================
If you are writing a freely available program and want to
internationalize it you are welcome to use GNU `gettext' in your
package. Of course you have to respect the GNU Library General Public
License which covers the use of the GNU `gettext' library. This means
in particular that even non-free programs can use `libintl' as a shared
library, whereas only free software can use `libintl' as a static
library or use modified versions of `libintl'.
Once the sources are changed appropriately and the setup can handle
the use of `gettext' the only thing missing are the translations. The
Free Translation Project is also available for packages which are not
developed inside the GNU project. Therefore the information given above
applies also for every other Free Software Project. Contact
`translation@iro.umontreal.ca' to make the `.pot' files available to
the translation teams.

This document details the incompatibilities between this version of bash,
bash-3.1, and the previous widely-available versions, bash-1.14 (which is
still the `standard' version for a few Linux distributions) and bash-2.x.
These were discovered by users of bash-2.x and 3.x, so this list is not
comprehensive. Some of these incompatibilities occur between the current
version and versions 2.0 and above. (The differences between bash-1.14 and
bash-2.0 were significant.)
1. Bash uses a new quoting syntax, $"...", to do locale-specific
string translation. Users who have relied on the (undocumented)
behavior of bash-1.14 will have to change their scripts. For
instance, if you are doing something like this to get the value of
a variable whose name is the value of a second variable:
eval var2=$"$var1"
you will have to change to a different syntax.
This capability is directly supported by bash-2.0:
var2=${!var1}
This alternate syntax will work portably between bash-1.14 and bash-2.0:
eval var2=\$${var1}
2. One of the bugs fixed in the YACC grammar tightens up the rules
concerning group commands ( {...} ). The `list' that composes the
body of the group command must be terminated by a newline or
semicolon. That's because the braces are reserved words, and are
recognized as such only when a reserved word is legal. This means
that while bash-1.14 accepted shell function definitions like this:
foo() { : }
bash-2.0 requires this:
foo() { :; }
This is also an issue for commands like this:
mkdir dir || { echo 'could not mkdir' ; exit 1; }
The syntax required by bash-2.0 is also accepted by bash-1.14.
3. The options to `bind' have changed to make them more consistent with
the rest of the bash builtins. If you are using `bind -d' to list
the readline key bindings in a form that can be re-read, use `bind -p'
instead. If you were using `bind -v' to list the key bindings, use
`bind -P' instead.
4. The `long' invocation options must now be prefixed by `--' instead
of `-'. (The old form is still accepted, for the time being.)
5. There was a bug in the version of readline distributed with bash-1.14
that caused it to write badly-formatted key bindings when using
`bind -d'. The only key sequences that were affected are C-\ (which
should appear as \C-\\ in a key binding) and C-" (which should appear
as \C-\"). If these key sequences appear in your inputrc, as, for
example,
"\C-\": self-insert
they will need to be changed to something like the following:
"\C-\\": self-insert
6. A number of people complained about having to use ESC to terminate an
incremental search, and asked for an alternate mechanism. Bash-2.03
uses the value of the settable readline variable `isearch-terminators'
to decide which characters should terminate an incremental search. If
that variable has not been set, ESC and Control-J will terminate a
search.
7. Some variables have been removed: MAIL_WARNING, notify, history_control,
command_oriented_history, glob_dot_filenames, allow_null_glob_expansion,
nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and
cdable_vars. Most of them are now implemented with the new `shopt'
builtin; others were already implemented by `set'. Here is a list of
correspondences:
MAIL_WARNING shopt mailwarn
notify set -o notify
history_control HISTCONTROL
command_oriented_history shopt cmdhist
glob_dot_filenames shopt dotglob
allow_null_glob_expansion shopt nullglob
nolinks set -o physical
hostname_completion_file HOSTFILE
noclobber set -o noclobber
no_exit_on_failed_exec shopt execfail
cdable_vars shopt cdable_vars
8. `ulimit' now sets both hard and soft limits and reports the soft limit
by default (when neither -H nor -S is specified). This is compatible
with versions of sh and ksh that implement `ulimit'. The bash-1.14
behavior of, for example,
ulimit -c 0
can be obtained with
ulimit -S -c 0
It may be useful to define an alias:
alias ulimit="ulimit -S"
9. Bash-2.01 uses a new quoting syntax, $'...' to do ANSI-C string
translation. Backslash-escaped characters in ... are expanded and
replaced as specified by the ANSI C standard.
10. The sourcing of startup files has changed somewhat. This is explained
more completely in the INVOCATION section of the manual page.
A non-interactive shell not named `sh' and not in posix mode reads
and executes commands from the file named by $BASH_ENV. A
non-interactive shell started by `su' and not in posix mode will read
startup files. No other non-interactive shells read any startup files.
An interactive shell started in posix mode reads and executes commands
from the file named by $ENV.
11. The <> redirection operator was changed to conform to the POSIX.2 spec.
In the absence of any file descriptor specification preceding the `<>',
file descriptor 0 is used. In bash-1.14, this was the behavior only
when in POSIX mode. The bash-1.14 behavior may be obtained with
<>filename 1>&0
12. The `alias' builtin now checks for invalid options and takes a `-p'
option to display output in POSIX mode. If you have old aliases beginning
with `-' or `+', you will have to add the `--' to the alias command
that declares them:
alias -x='chmod a-x' --> alias -- -x='chmod a-x'
13. The behavior of range specificiers within bracket matching expressions
in the pattern matcher (e.g., [A-Z]) depends on the current locale,
specifically the value of the LC_COLLATE environment variable. Setting
this variable to C or POSIX will result in the traditional ASCII behavior
for range comparisons. If the locale is set to something else, e.g.,
en_US (specified by the LANG or LC_ALL variables), collation order is
locale-dependent. For example, the en_US locale sorts the upper and
lower case letters like this:
AaBb...Zz
so a range specification like [A-Z] will match every letter except `z'.
Other locales collate like
aAbBcC...zZ
which means that [A-Z] matches every letter except `a'.
The portable way to specify upper case letters is [:upper:] instead of
A-Z; lower case may be specified as [:lower:] instead of a-z.
Look at the manual pages for setlocale(3), strcoll(3), and, if it is
present, locale(1).
You can find your current locale information by running locale(1):
caleb.ins.cwru.edu(2)$ locale
LANG=en_US
LC_CTYPE="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_COLLATE="en_US"
LC_MONETARY="en_US"
LC_MESSAGES="en_US"
LC_ALL=en_US
My advice is to put
export LC_COLLATE=C
into /etc/profile and inspect any shell scripts run from cron for
constructs like [A-Z]. This will prevent things like
rm [A-Z]*
from removing every file in the current directory except those beginning
with `z' and still allow individual users to change the collation order.
Users may put the above command into their own profiles as well, of course.
14. Bash versions up to 1.14.7 included an undocumented `-l' operator to
the `test/[' builtin. It was a unary operator that expanded to the
length of its string argument. This let you do things like
test -l $variable -lt 20
for example.
This was included for backwards compatibility with old versions of the
Bourne shell, which did not provide an easy way to obtain the length of
the value of a shell variable.
This operator is not part of the POSIX standard, because one can (and
should) use ${#variable} to get the length of a variable's value.
Bash-2.x does not support it.
15. Bash no longer auto-exports the HOME, PATH, SHELL, TERM, HOSTNAME,
HOSTTYPE, MACHTYPE, or OSTYPE variables.
16. Bash no longer initializes the FUNCNAME, GROUPS, or DIRSTACK variables
to have special behavior if they appear in the initial environment.
17. Bash no longer removes the export attribute from the SSH_CLIENT or
SSH2_CLIENT variables, and no longer attempts to discover whether or
not it has been invoked by sshd in order to run the startup files.
18. Bash no longer requires that the body of a function be a group command;
any compound command is accepted.
19. As of bash-3.0, the pattern substitution operators no longer perform
quote removal on the pattern before attempting the match. This is the
way the pattern removal functions behave, and is more consistent.
20. After bash-3.0 was released, I reimplemented tilde expansion, incorporating
it into the mainline word expansion code. This fixes the bug that caused
the results of tilde expansion to be re-expanded. There is one
incompatibility: a ${paramOPword} expansion within double quotes will not
perform tilde expansion on WORD. This is consistent with the other
expansions, and what POSIX specifies.
21. A number of variables have the integer attribute by default, so the +=
assignment operator returns expected results: RANDOM, LINENO, MAILCHECK,
HISTCMD, OPTIND.
22. Bash-3.x is much stricter about $LINENO correctly reflecting the line
number in a script; assignments to LINENO have little effect.
23. By default, readline binds the terminal special characters to their
readline equivalents. As of bash-3.1/readline-5.1, this is optional and
controlled by the bind-tty-special-chars readline variable.
24. The \W prompt string expansion abbreviates $HOME as `~'. The previous
behavior is available with ${PWD##/*/}.
25. The arithmetic exponentiation operator is right-associative as of bash-3.1.
26. The rules concerning valid alias names are stricter, as per POSIX.2.
27. The Readline key binding functions now obey the convert-meta setting active
when the binding takes place, as the dispatch code does when characters
are read and processed.
28. The historical behavior of `trap' reverting signal disposition to the
original handling in the absence of a valid first argument is implemented
only if the first argument is a valid signal number.
29. In versions of bash after 3.1, the ${parameter//pattern/replacement}
expansion does not interpret `%' or `#' specially. Those anchors don't
have any real meaning when replacing every match.
30. Beginning with bash-3.1, the combination of posix mode and enabling the
`xpg_echo' option causes echo to ignore all options, not looking for `-n'

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
The Free Software Foundation has exempted Bash from the requirement of
Paragraph 2c of the General Public License. This is to say, there is
no requirement for Bash to print a notice when it is started
interactively in the usual way. We made this exception because users
and standards expect shells not to print such messages. This
exception applies to any program that serves as a shell and that is
based primarily on Bash as opposed to other GNU software.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the

This is correct according to Posix 1003.2a draft 5. An alias must obey this
pseudo-regexp:
[a-zA-Z_][a-zA-Z0-9_]*
(That is, only letters, digits, and underscores, and it may not begin with an
underscore). This is in the latest version of the manual page, the one in
the documentation directory.

I am sorting through this problem right now, and I've discovered a few things
(none complimentary to Sun).
First of all, this crash happens because Sun's programmers are lazy. The Sun
malloc allows you to free things multiple times, instead of doing the old
if (x)
free(x);
x = NULL;
trick. The Gnu malloc disallows that.
The root of this set of problems is that the Sun yyparse() is not reentrant
(`impure'). First of all, /usr/lib/yaccpar has changed a number of things
to be dynamically allocated that were once static arrays (the state stack
and the value stack are the two major ones). Second, some things that used
to be automatic variables to yyparse (like the state stack) are now
globally static variables in /usr/lib/yaccpar. This means no more
indirectly recursive calls to yyparse(). This is pure bogusness, and
breaks backwards compatibility in a major way.
The first indirect call to yyparse() occurs when PROMPT_COMMAND is run
through parse_and_execute() (parse.y, around line 1200). The next call to
yyparse() in your example (hitting return) returns quickly, putting nothing
onto the state stack. Of course, YYACCEPT doesn't check whether anything
was put into the stack; it just goes ahead and frees it anyway.
The next problem arises when PROMPT_COMMAND contains a backquoted command,
which is run through parse_and_execute() again. It doesn't matter that
this parse_and_execute is in a subshell; the data structures being built by
Sun's yacc come along for free when bash forks. The state stack gets all
screwed up and a segmentation fault is the inevitable result. If Sun (and,
I assume, AT&T, since the SCCS line at the top of /usr/lib/yaccpar
indicates that it is derived from S5R3.1) wants to do this kind of shit,
they should at least provide a convenience function to clear out the state
stack.
Both of these problems are avoided by using bison. I have put bison on
triton (you'll have to redo it if you want it; it looks for the parser
skeletons in /home/chet/lib), and a bash compiled with a bison-generated
parser does not crash given the above setting of PROMPT_COMMAND. That bash
is in /home/chet/bin. I don't know how to solve these problems in a
simple way by using the Sun yacc.
`Byacc' (Berkeley Yacc), the 4.4 BSD rewrite of Yacc by Bob Corbett (who
wrote the original version of bison), should also be OK, though I haven't
looked at it.

(It's CWRU, by the way.)
Don't worry, I get them all. Look at the end of shell.c (make_bug_report)
where it opens a pipe to `/bin/rmail chet@ins.cwru.edu'.
Let me know of any more problems you encounter.

This is a bug alright, but it's a bug with rshd that's not fixed until
4.3-reno.
rshd sets up a pipe (int pv[2]; if you have the source to the tahoe rshd)
to the process it executes and uses it to manage error and control output
from over the net. In the child process, it does a dup2(pv[1], 2), but
never calls close(pv[1]). Adding that code to the 4.3-tahoe rshd makes it
(and the Xemacs script) work right.
I don't know how to solve this cleanly in bash. Doing a blanket close of
all open file descriptors < 2, < 20 is a no-no, especially when we're not
interactive. csh `works' because it does the blanket close on startup, but
csh can get away with doing that because it doesn't let you manipulate
arbitrary file descriptors.

This is a result of bash using the BSD-style tty driver on Ultrix. The BSD
driver ties input and output carriage return translation together with the
CRMOD bit. (The CRMOD bit causes CR->LF translation on input and LF->CRLF
translation on output.) Unless the CRMOD bit is cleared, it is impossible
to get a literal ^M in an input line. Unfortunately, one of the effects of
clearing it is the loss of output processing you've observed.
The Ultrix Posix-style tty driver can't be used because it has serious
problems with losing typeahead when ICANON is switched on and off. These
characters seem to reappear later without warning, usually when a
program that uses the BSD-style ioctls turns on CBREAK (e.g., `more').

I found this bug a few days ago and was about to send a bug report
to ISC. The problem is "simply" a NULL pointer reference in the
namei() function. The machine I found this on runs ISC 2.21 with
the security fix installed. I fixed this bug with a binary patch. It
is for the module /etc/conf/pack.d/kernel/os.o. I disassembled the
original and then the fixed version of os.o and ran a context diff
over the output. Depending on what version of the kernel config kit
you have the addresses might be off some bytes. You can apply this
patch with every binary file editor.

I'm not absolutely sure whether the action that is now taken in case of
a NULL pointer is the right one, but I haven't noticed any problems,
and most important, there are no more kernel panics! At least not from
that spot. :-) The action that is taken if the pointer in _not_ NULL
hasn't changed (this is not very obvious from the patch, but look
in the disassembler listing of your own kernel for more details).
I use this modified kernel for over a week now and it works for
me. Of course, as always, I can't give you any guaranty that this
patch does something useful on your machine. :-)
Hope this helps you.
Uwe
PS: ISC, if you see this posting, could you drop me a note on whether
you have put this on your to-do list? This would save me the time
needed to file an official bug report.

Here is a copy of my recent note to Uwe:
I've applied the binary patch that you recently poosted to comp.unix.sysv386
for os.o.
It works beautifully. Previously, I had compiled bash1.07CWRU, and it worked
well (using POSIX job control), job control and all -- but running VP/ix under
this bash caused a system panic. This evidently is the (now infamous) "POSIX
namei bug". After rebuilding the kernel with a patched os.o, the problem
simply disappeared. VP/ix, like everything else, now works fine under
bash1.07CWRU.

It's getting stuck in initialize_jobs (). There is a bug in the NeXT
/usr/etc/rlogind that causes bash to be started with the terminal still
belonging to the rlogind process, and its process group set to 0 (so
that getpgrp() returns 0 (!)). It looks like there's a stray setpgrp(0, 0)
in the rlogind code that NeXT is not handling like 4.3 BSD.
(Another bug that I've found with NeXT 2.0 is that Terminal starts up the
shell underneath it with argc == 0 and argv[0] = "-". Not polite.
`mount -vat nfs' seems to be broken too. Any more good ones I should look
for?)
Here's a diff to jobs.c to work around it. Your line numbers will certainly
vary (for all I know, the code might, too).

You can't run bash-1.12 on a 3.2.4 system if it's been compiled on a
3.2.2 system. Bash contains a fix for the broken sigsuspend in 3.2.2
that breaks bash on 3.2.4, because 3.2.4 has the bug fixed.
Bash 1.12 should build and run OK out of the box on 3.2.2. For 3.2.4
you need to locate the code at around line 1250 of jobs.c and change
#if !defined (SCO) to #if 1 so that sigsuspend is used. Then take out
the SCO defines in flush_child().

I fixed it. Sequent's fcntl and dup2 are both messed up. They do not set
the new descriptor to be open-on-exec. For dup2 it's OK; that's the way
4.2 BSD did it. fcntl doing it is a bug, and a bad one.

This is a bug in the Sun YP code that everyone seems to have picked up.
Sun keeps static state in the YP library code -- a pointer into the
data returned from the server. When YP initializes itself (setpwent),
it looks at this pointer and calls free on it if it's non-null. So far,
so good.
If one of the YP functions is interrupted during getpwent (the exact function
is interpretwithsave()), and returns NULL, the pointer is freed without being
reset to NULL, and the function returns. The next time getpwent is called,
it sees that this pointer is non-null, calls free, and the Gnu free()
blows up because it's being asked to free freed memory.
The traditional Unix mallocs allow memory to be freed multiple times; that's
probably why this has never been fixed. You can probably stop it by adding
an #undef USE_GNU_MALLOC to the appropriate machine description in machines.h.

Typeahead under Ultrix is wierd. This doesn't happen anywhere else. Here's
what it does for me:
cwjcc$ sleep 4
echo hi ; echo hi <----- typeahead while sleeping
cwjcc$ <----- nothing comes out
cwjcc$ more readline.c
readline.c: No such file or directory
cwjcc$ echo hi ; echo hi <----- now it does...
hi
hi
I'll look at it today.
> - The sequence

This only happens under Ultrix, too. It's another consequence of Dec's
dup2 fuckup (I am *really*pissed*off* about it; it's caused me to waste a
lot of time already). File descriptor 1 is getting set to close-on-exec.
I haven't decided whether to hack around it in the code or to just make
Ultrix use the dup2 emulation in general.c.
Cheers,
Chet

Starting bash with the `--posix' command-line option or executing
`set -o posix' while bash is running will cause bash to conform more
closely to the Posix.2 standard by changing the behavior to match that
specified by Posix.2 in areas where the bash default differs.
The following list is what's changed when `posix mode' is in effect:
1. When a command in the hash table no longer exists, bash will re-search
$PATH to find the new location. This is also available with
`shopt -s checkhash'.
2. The >& redirection does not redirect stdout and stderr.
3. The message printed by the job control code and builtins when a job
exits with a non-zero status is `Done(status)'.
4. Reserved words may not be aliased.
5. The Posix.2 PS1 and PS2 expansions of `!' -> history number and
`!!' -> `!' are enabled, and parameter expansion is performed on
the value regardless of the setting of the `promptvars' option.
6. Interactive comments are enabled by default. (Note that bash has
them on by default anyway.)
7. The Posix.2 startup files are executed ($ENV) rather than the normal
bash files.
8. Tilde expansion is only performed on assignments preceding a command
name, rather than on all assignment statements on the line.
9. The default history file is ~/.sh_history (default value of $HISTFILE).
10. The output of `kill -l' prints all the signal names on a single line,
separated by spaces.
11. Non-interactive shells exit if `file' in `. file' is not found.
12. Redirection operators do not perform pathname expansion on the word
in the redirection unless the shell is interactive
13. Function names must be valid shell identifiers. That is, they may not
contain characters other than letters, digits, and underscores, and
may not start with a digit. Declaring a function with an illegal name
causes a fatal syntax error in non-interactive shells.
14. Posix.2 `special' builtins are found before shell functions during command
lookup.
15. If a Posix.2 special builtin returns an error status, a non-interactive
shell exits. The fatal errors are those listed in the POSIX.2 standard,
and include things like passing incorrect options, redirection errors,
variable assignment errors for assignments preceding the command name,
and so on.
16. The environment passed to executed commands is not sorted. Neither is
the output of `set'. This is not strictly Posix.2 behavior, but sh
does it this way. Ksh does not. It's not necessary to sort the
environment; no program should rely on it being sorted.
17. If the `cd' builtin finds a directory to change to using $CDPATH, the
value it assigns to $PWD does not contain any symbolic links, as if
`cd -P' had been executed.
18. A non-interactive shell exits with an error status if a variable
assignment error occurs when no command name follows the assignment
statements. A variable assignment error occurs, for example, when
trying to assign a value to a read-only variable.
19. A non-interactive shell exits with an error status if the iteration
variable in a for statement or the selection variable in a select
statement is a read-only variable.
20. Process substitution is not available.
21. Assignment statements preceding POSIX.2 `special' builtins persist in
the shell environment after the builtin completes.
There is other Posix.2 behavior that bash does not implement. Specifically:
1. Assignment statements affect the execution environment of all builtins,
not just special ones.

It would be nice to have a general completion feature like this.
Until that happens, maybe you will find the following patch useful.
It makes MH folder name completion work with bash. The diffs are
relative to version 1.14.2.
I realize that changes to readline.c and and complete.c are not good
since they add some MH-specific stuff to the readline code and not to
bash, but when I first wrote this, I had no idea what else to do.
Chet, would you consider adding this if it were cleaned up a bit?
Made optional with cpp conditionals?
This feature has been very useful to me for the last several years
(since about 1.05 or 1.06, I think).

This file details the changes between the previous release of CWRU bash
(3/10/93) and this release.
1. Bugs Fixed
New version of endian.c that handles 64-bit machines better
added code to make readline reset itself when $TERMINFO changes
fixed memory leaks in:
builtins/exec.def
lib/readline/history.c
lib/readline/readline.c
parse.y
subst.c
variables.c
dispose_cmd.c
mailcheck.c
bashline.c
execute_cmd.c
shell.c
make sure that bash_symbolic_link_hook calls get_working_directory with a
non-empty string argument
check the return value of getdtablesize() for bad values
make the job control tty handlers print error message only if the shell is
currently interactive
process substitution no longer tries to close every file descriptor
fixed up the source to contain more extern function declarations rather than
casting the return values
fixed up handling of embedded quoted strings by the parser so that $ is not
a special character while parsing one
added escape handling to the read builtin so backslashes can escape $IFS
characters
fixed the brace expansion code so that backslash can act as a delimiter and
can escape `"' in a double-quoted string
the `<>' redirection needs to open the file O_RDWR|O_CREAT for Posix.2
compatibility
fixed up the here document reading code so that it will remove backslash-
quoted newlines if the document delimiter is not quoted
fixed up the unwind_protect_var code so that the same strategy is used
for both saving and restoring variables
completion functions may now tell readline not to attempt filename completion
by returning (char **) -1
improved the error message printed by get_working_directory
Compile for solaris if either USGr4 or __svr4__ is defined
bash does not perform a getwd() on startup unless the inherited value of
$PWD is wrong or $PWD was not in the environment
fixed up the trap saving and restoring code so that savetrap=$(trap) works
like Posix.2 says it should
non-interactive shells are now much better about cleaning up dead processes
and jobs on both job control and non job control systems
fixed the code that saves and restores the dollar variables around a `.'
script so that if the script changes the positional parameters, the old
values are not restored
fixed the tokenizer so that it will not return ASSIGNMENT_WORD while
parsing a case statement pattern list
redid the implementation of cprintf for systems without varargs
fixed up the variable expansion code so that illegal variable names in ${ }
expansion now generate errors rather than produce incorrect results
fixed up some problems with default_buffered_input and the implicit redirection
of fd 0 to /dev/null for asynchronous commands without job control
new function internal_error for shell internal error messages
changed the sigint signal handler in nojobs.c to do nothing when it's called,
not even run a signal handler
made the command substitution code more careful about file descriptors when
errors occur
2. New Features
SIGWINCH causes bash to reset the values of $LINES and $COLUMNS for both
readline and non-readline systems
changed the code in readline that handled conditional parsing of `$if term='
to test the terminal name given to $if against both the `long' and `short'
(portion up to the first `-') forms of the terminal name
the completion code now single-quotes a match that contains a shell word
break character
the readline code does not define USE_XON_XOFF. This causes output to be
swallowed when using bash over a relatively slow line (like a modem line).
there is now a bindable readline function to do only history expansion;
bound to M-^ (M-! was already taken)
ulimit now has a -u option to set and get the limit for the maximum number
of user processes
config.h.mini is a `minimal' configuration file that compiles out just about
everything

This file details the changes between the previous release of CWRU bash
(5/10/93) and this release.
1. Bugs Fixed
commas within backquotes inside matching braces are now treated as
quoted (e.g., echo {`echo foo:bar | sed s/:/,/`})
don't create the export env unless we are running a command with
shell_execve (in execute_disk_command), and don't create it anew
each time a child is forked
make execute_disk_command look in the temp environment for an
assignment to PATH, and disable hash lookup for the command if
such an assignment is present
fixed here documents so that backslash-quoted newlines are treated as
Posix.2 specifies
removed a number of extraneous unwind-protects or moved them inside
if statements
only call rl_reset_terminal in sv_term if we're actually using readline
only run traps on SIGCHLD if job_control != 0
fixed readline so it won't try to pass memory allocated with alloca() to
a separate function
cleaned up the readline global function and variable namespace, and split
some more code out from readline.c into separate files
added header files that declare extern functions rather than having those
extern declarations littered throughout the code
readline now allows ^T to be undone
fixed readline so that characters whose screen representation is > 1
character (e.g., \354) are erased correctly
the read builtin no longer attempts to split its input into words if
$IFS is unset
changed the terminating signals that bash catches so they're reset to
their original handlers when a child is forked
the Gnu malloc library code was upgraded to Gnu libc version 1.06
the Gnu termcap library code was upgraded to Gnu termcap version 1.02
the man page was updated to cover the bind -m option
2. New Features
Bash now notices if it's running setuid or setgid and disables $ENV
processing and importing shell functions from the environment
New flag: -p/-o privileged, set if the shell is running setuid or setgid.
Turning this off causes the effective uid and gid to be set to the
real uid and gid
New machine descriptions for the Intel Paragon, Symmetric 375, NeXT 486,
and HP running 4.4 BSD

This file details the changes between the previous release of CWRU bash
(07/11/93) and this release.
1. Bugs Fixed
Readline's vi-mode once again has TAB bound to completion; entering `posix
mode' changes it to self-insert
Bash now binds its special emacs-mode functions directly into
emacs_meta_keymap so that eight-bit character handling does not interfere
Some source restructuring: more extern functions are defined in header files
and not in C source files
The handling of `line number' inside functions is now more correct and
closer to reality
Some functions of `general use' were moved to general.c (vfree,
full_pathname)
A bug that caused some redirections to be applied twice was fixed in
execute_command_internal (dispose of redirection_undo_list after copying it;
ditto for exec_redirection_undo_list)
The exit status of a command that is not found is 126, as Posix.2 specifies
More speed improvements -- bash now runs as fast as the SunOS sh on
Haertel's `shell benchmark'
Instead of returning pointers to -1, bash and the readline, history, and
glob libraries now return pointers to special `error pointers', which the
calling code checks for in place of -1
Fixed a problem with canonicalize_pathname which made it get
confused with xxx/./yyy if yyy was `.' or `..'
Fixes to make bash recognize SVR4.2 and set USGr4_2 for SVR4.2 systems
Fixes to the HP/UX machine descriptions to make alloca work on HPUX_9
and to avoid `M_MACHINE redefined' warnings
Fixes to the CRAY machine description
Fixes to the mailpath code to make it Posix.2-compliant -- backslash
may now quote `%' and `?'
The namespace was further cleaned up, and more functions and variables
were made static
On systems with S_IFSOCK or S_ISSOCK defined in sys/stat.h, bash checks
whether fd 0 is a socket to decide whether or not it's being started by
rshd and to run the startup files
Bash now gives the signal mask it inherits to its children -- previously,
login shells cleared the signal mask
cpp-Makefile and subst.c both used the `USE_GLOB_LIBRARY' define, but
with different meanings; subst.c now uses `USE_POSIX_GLOB_LIBRARY'
Fixed pattern substitution so that ${a%%$b}, where b was unset, no longer
causes a core dump
Changed the `test_exit' define in test.c to no longer use `longjmp' as
the rhs or a comma-ized expression; this causes core dumps on some
optimizer/machine combinations
A speed hack in variables.c: if no local variables are defined for a level
of shell context, kill_all_local_variables does not need to search the
whole variable hash table when popping a context
Fixed the `bind' builtin so that -m now changes the keymap for all of the
subsequent operations
Changed some more builtins to use internal_getopt: bind, command, export,
readonly, declare, typeset
Fixed fc to use the Posix.2 format for listing commands in the
history list
Changed bg to set `!', as Posix.2 specifies
Fixed ulimit.def to compile if RLIMIT_RSS is not defined,
as some systems seem to have it
Replaced lib/malloc/alloca.c with the version from emacs 19. The old one
lives in alloca.c.old
malloc.c now uses the ANSI C features to `stringize' macro arguments if
__STDC__ is defined
Fixes to the GNU malloc library from glibc 1.06 and Mike Haertel
Fixes to readline key binding and lookup for Cray systems, which don't
like the casting that readline does
Fixes to all readline library source files to clean up the code: make sure
`int'-returning functions use `return x;' rather than `return;', declare all
arguments, even the `int' ones, and make some functions void. Cleaned up
the code formatting a little, too.
The readline completer now double-quotes filenames with special word-break
characters, so that tilde expansion still works
^C now breaks out of keyboard macros
If being compiled as part of the shell, readline no longer attempts to
handle SIGTTIN, SIGTTOU, or SIGTSTP
tilde_expansion_failure_hook is now a CPFunction rather than a Function,
since that's how it's used
Readline vi-mode `change case' function now skips over characters which
are neither upper nor lower case
Readline vi-mode now allows replacement to be redoable with `.'
2. New Features
A `strict Posix.2' mode, enabled with the -posix startup option or
setting the POSIXLY_CORRECT variable (see CWRU/POSIX.NOTES for a
description of the changed behavior)
`ONESHOT' is now an option in config.h
cpp-Makefile assumes that fixed header files are present if gcc is being
used
The redirections attached to a function declaration are now part of that
function, applied when the function is executed, as specified by Posix.2.
This caused a change to parse.y that resulted in 66 shift/reduce
conflicts(!)
All of the OP= functions that Posix.2 specifies are now implemented for
both `let' and arithmetic substitution
The `command' builtin has acquired the Posix.2 `-v' and `-V' options
(this shares code with the `type' builtin)
A new `bash_builtins' man page, like the `csh_builtins' page on some
systems

This documents the changes between the first `public' release of CWRU bash
and this, its second release. It summarizes, without going into detail,
the changes that have been made.
NEW FEATURES
o `getopts' builtin, as specified by Posix.2
o new configuration variable HAVE_UNISTD_H, used to include
<unistd.h> and test for Posix features
o `ulimit' has new -p and -n options to report the pipe buffer size
and number of available file descriptors, respectively
o allow SIGCHLD to be trapped and useful behavior to result if it is
o Posix termios and signal code for readline and the shell itself
o can optionally use the GNU termcap library
o new output for `times' builtin that looks like ksh:
shell-user shell-sys
child-user child-sys
o `ulimit' limits now apply to both shell and its children
o new machines.h entries
o no longer does the costly `close file descriptors 3-NOFILE'
each time it exec's a program -- now uses the close-on-exec
flag for the files it fiddles with
NOTABLE BUG FIXES
o jobs.c only sets and gets the tty state in an interactive shell
o bash does better process group checking on Posix systems, eliminating
some error messages
o fix for `infinite login' bug on System V machines when executing a
script from a .bash_profile
o the `trap' command now behaves as 1003.2 specifies, as of draft 9
o restore original terminal process group upon exit, so as to not
confuse a parent Bourne shell
o `bash file', where `file' is a binary file, now reports an error
o shells started with `-s' now execute the .bashrc file
CHANGES (by date and files affected)
9/20 - 9/30
-----------
builtins.c, builtins.c.posix
- added getopts help text
- removed extra "let" from `let' error message
- added correct extern definition for list_rest_of_args() to shift
builtin
jobs.c, jobs.c.posix
- removed bogus call to set_process_resource_limits() from
make_child() as a consequence of redoing `ulimit'
- initialize shell_tty to -1
- only get or set the tty state after a command completes if the shell
is interactive
- use shell_tty in get_tty_state() and set_tty_state() instead of
reopening /dev/tty every time
jobs.c.posix
- do better pgrp checking in initialize_jobs() to avoid error message
about not being able to setpgid(2) on startup
- changed tcsetattr() error messages slightly
expr.c
- avoid advancing beyond the end of the expression when reporting an
error
- NULL expressions now return 0 ($[], for example)
mailcheck.c
- #ifdef redundant definition of NOW, which is also defined in
general.h
variables.c
- initialize $OPTIND and $OPTERR to 1 for getopts
- add correct extern definition for itos()
subst.c
- if $IFS is unset, it defaults to " \t\n"
- add special variable hack functions for $OPTIND, $OPTERR
builtins.h
- add definition for getopts_builtin()
getopts.c
- new file, source for `getopts' builtin command
ulimit.c
- remove the `struct ResourceLimit' stuff; limits now apply to both
the shell and its children
- took out set_process_resource_limits(), let ulimit(2) or
setrlimit(2) do the work
- changed error messages to use builtin_error() instead of
report_error()
- changed the block factor for RLIMIT_CPU from 1000 (milliseconds)
to 1 (seconds)
10/1
----
builtins.c, builtins.c.posix
- changed `test' help text for -ef option
- made `trap -' reset all signals to their original values
machines.h
- added a new configuration variable, HAVE_UNISTD_H, which should
be defined if /usr/include/unistd.h exists
cpp-Makefile
- make HAVE_UNISTD_H show though from machines.h to the bash code
- add an explicit build line for ulimit.o so `psize.sh' is run
each time ulimit.o is remade. This is kind of flaky.
config.h
- include <unistd.h> if HAVE_UNISTD_H is defined, use it to test
for various Posix features (job control, signals, termios)
jobs.c, jobs.c.posix
- restore original signals to child process in make_child()
- keep count of number of children that exit or stop in flush_child(),
and call a trap handler for SIGCHLD that many times. This allows
SIGCHLD to be trapped without disaster occurring.
shell.c
- If we're on a Posix system, initialize signals the Posix way
- clear signal mask in initialize_signals() if on Posix system
- set login_shell and make_login_shell to 0 upon entry to main(),
solving the System V infinite login bug
trap.c
- preserve value of $? when running traps
- don't allow a signal ignored upon entry to the shell to be trapped
or reset to the default
- do not allow trapping SIGCHLD to change the signal handler, but
save the commands to be executed. Run these commands from the
SIGCHLD signal handler for each child that exits or stops
- don't allow SIGCHLD signal handler to be overridden or have SIGCHLD
ignored
- new function added to restore all trapped signals to their original
values
ulimit.c
- add new -p option to report pipe buffer size. This is flaky on
all non-Posix systems (those that do not define PIPE_BUF).
readline/readline.c
- add Posix termios and signal code
10/2
----
jobs.c, jobs.c.posix
- only fetch terminal state in initialize_jobs() if the shell is
interactive
10/3
----
machines.h
- new entry for Stardent
- new variable USE_TERMCAP_EMULATION, for those systems that have the
termcap(3) functions in the curses library, but have not linked
/usr/lib/libtermcap.a to libcurses.a
cpp-Makefile
- use USE_TERMCAP_EMULATION to set TERMCAP and TERMLIB
siglist.c, alias.h, general.c
- declare the return values of xmalloc() and malloc() for the benefit
of machines which cannot cope with simply casting the return value
shell.c, execute_cmd.c
- change the re-execution of main() when executing a shell script to
use setjmp/longjmp
builtins.c
- add code to change the shell level in exec_builtin(), decrementing
it before trying the execve(2) and incrementing it again if that
fails
variables.c
- new function adjust_shell_level() to change shell level by a
specified increment
- initialize `noclobber' in shell_initialize(), if we have inherited
the `noclobber' variable from a parent shell
ulimit.c
- add new option -n, which reports the max number of available file
descriptors as reported by getdtablesize(). On SunOS 4.1, this
can be set, too, with setrlimit(RLIM_NOFILE, ...).
10/4
----
readline/readline.c
- Ultrix turns off system call restart when executing in `Posix mode'
(when sigaction(3) is used to set signal handling), so make it use
the System V version of shell_getc()
jobs.c.posix
- fix a bug in start_job() where `oset' was not initialized in the first
call to sigprocmask(), yet was used in subsequent calls
- remove the `shadow' instance of shell_tty_info in the code that sets
the line discipline in initialize_jobs()
shell.c
- if job control is being used, restore the tty pgrp to its original
value so as to not screw the parent
builtins.c, builtins.c.posix
- make the output of `times' look more like ksh
10/5
----
jobs.c.posix
- HP/UX no longer needs the signal handler for SIGCHLD reset via a
call to signal() in flush_child() -- this breaks job control
machines.h
- add HAVE_VPRINTF to HP/UX entry
siglist.c
- include <stdio.h>, sprintf(3) requires it on some systems
10/8
----
execute_cmd.c
- make $LINENO in a function count the number of simple commands
executed
10/9
----
termcap, cpp-Makefile
- new GNU termcap library, cribbed from Emacs. #define
USE_GNU_TERMCAP in machines.h entry to use it. Small changes
required to cpp-Makefile to make it work. This works on
4.3 BSD, at least.
machines.h
- add new entry for AIX/370
general.c
- sysv_getc() is also needed for Ultrix machines running in Posix
mode, so change the #ifdef accordingly (Ultrix passes the
SV_INTERRUPT flag to sigvec(2) in sigaction(3)).
subst.c
- use sysv_getc() for Ultrix machines running in Posix mode for
command subsitution pipe reading
10/10
-----
shell.c, execute_cmd.c
- if the `file' portion of `bash file' is a binary file, report an
error and do not attempt to execute it
jobs.c, jobs.c.posix
- the code that does the guts of `kill' now sends the SIGCONT to a
stopped job after it sends the specified signal, not before
10/11
-----
parse.y
- set +H also turned off putting commands into the history list
shell.c
- make shells started with -s read .bashrc
10/14
-----
expr.c
- changed calls to `report_error' to call `builtin_error'. I don't
know if this is exactly right, but it seems to me that an error
in an expression shouldn't kill the shell if -e is set.
fc.c
- changed `report_error' to `builtin_error'
10/16
-----
readline/vi_mode.c
- repeat count to rl_vi_subst() was incorrectly being ignored
- don't call rl_vi_change_case() on an empty line; two calls in
a row can cause a seg fault
10/17
-----
execute_cmd.c
- give builtins run in pipes a useful setting of top_level to
longjmp(2) to on errors
builtins.c, builtins.c.posix
- replace some occurrences of longjmp (top_level, ...) with simple
calls to return (EXECUTION_FAILURE)
10/18
-----
readline/readline.c
- Make O_NDELAY be the same as O_NONBLOCK on Posix systems
- Don't use IXANY if it's not defined (some strict Posix systems do
not define it)
- Posix systems need NOFLSH for c_lflag to avoid flushing the input
buffer after a SIGINT, SIGQUIT, or SIGSUSP. This is still wrong,
though.
execute_cmd.c, test.c, general.h
- use the Posix S_IS* macros to test file formats instead of explicitly
masking with S_IFMT and testing the result. Macros are provided
for those systems that do not have them (like 4.3 BSD).
parse.y
- fix expansion of \W in the prompt string so that it works when
you're in the root directory
machines.h
- add machine description for concurrent in UCB universe
Makefile
- make sure $(MFLAGS) is passed to the recursive make of bash-Makefile
10/22
-----
jobs.c.posix
- make sure the NOFLSH bit is turned on in the termios c_lflag word
so that typeahead doesn't get flushed on receipt of signals. THIS
HAS BEEN TAKEN OUT.
10/23
-----
execute_cmd.c
- change extract_colon_unit() to increment the path index past a
colon when it is called, before it tries to get the next component
from the path. Without doing this, `.' was always found as the
second component in the path, whether it was actually there or not.
trap.c, shell.c
- made SIGINT trap handling act the same as that of ksh and the BSD
sh. As a side effect (really the reason for doing this in the
first place), `read' is now interruptible.
Makefile
- made the CPPFLAGS definition useful by passing it to cpp when
making bash-Makefile from cpp-Makefile
- made the `echo' line when creating bash-Makefile really echo by
quoting the redirection to bash-Makefile
general.c
- make fcntl.h be included only if NO_DUP2 is defined
10/24
-----
cpp-Makefile
- make libreadline.a depend on the objects, not the sources. Without
this, you could delete on of the .o files to try to force a library
rebuild and have it not happen.
10/25
-----
shell.c
- make a flag of `-' signal the end of option arguments, like the
4.3 BSD sh, and in accordance with the Posix command line syntax
standard
shell.c, builtins.c, builtins.c.posix
- shuffle some code around so -o option can be given on the command
line -- there's no reason why it shouldn't be allowed.
variables.c, variables.h, execute_cmd.c, builtins.c, builtins.c.posix, shell.c,
subst.c, bashline.c, hash.h, variables.h
- change the implementation of shell function and variable storage to
a hash table instead of a singly-linked list
make_cmd.c, shell.c
- bug reports only get mailed out if MAIL_BUG_REPORTS is defined
10/29
-----
bashline.c
- some random cleanups from bfox
- make sure alias expansion is attempted in shell_expand_line () only
if ALIAS is defined
hash.c
- add default case to make_hash_table to force the number of buckets
in the table to be the default if 0 is passed as the number of
buckets
variables.c
- make initialize_shell_variables () call make_hash_table () with an
argument of 0 again (see previous entry).
variables.c, builtins.c, builtins.c.posix
- cleanups because map_over(), all_vars(), all_shell_variables(), and
all_shell_functions () can possibly return NULL lists, and such
lists should not be sorted or freed
trap.c
- make sure we declare `extern int last_command_exit_value' in
run_interrupt_trap ().
variables.c
- Don't override a HOSTTYPE variables that comes in from the
environment
10/30
-----
variables.c
- Fix a bug in variables.c: make_var_array () where it called
array_len on a NULL list
builtins.c, builtins.c.posix
- Add a description of `-m' to the help for the `set' builtin
command
11/1
----
general.c
- added a definition of bzero() for USG machines, because
there is a reference to it in the new variable hashing code
11/2
----
shell.c
- set forced_interactive to 0 in shell_reinitialize(), otherwise
shell scripts get marked as interactive
11/6
----
execute_cmd.c
- eliminated the costly loop from 3 to NOFILE closing all file
descriptors each time we exec a command by setting all file
descriptors > 2 opened as the result of a redirection and internal
to the shell to be close-on-exec, as well as all file descriptors
opened to save others in add_undo_redirect(). `internal to the
shell' means that the redirections were attached to shell builtin.
Other `internal' redirections include while, for, and until
loops, and shell functions. I got scared after reading that
s5r4 provides 2048 fd's per process -- 2045 (mostly useless)
close() calls on *each executed program*? No way, no how.
This caused the other fixes for this file to be discovered.
Unfortunately (there always seems to be a catch), 4.3 BSD up to
4.3-tahoe leaves a file descriptor open in setpwent() if you're
using dbm password files. 4.3+NFS does this if you're not using
YP. Arghhhhhhh... I haven't decided yet what to do about this;
probably just set fd 3 to close-on-exec when the shell is
initialized.
execute_cmd.c
- removed the call to `add_undo_redirect()' when a file is being
closed with the redirection operators [n]<&- and [n]>&-. The
effect was to make those operators useless. Sad to say, I was
probably the dummy who put it in there...
execute_cmd.c
- when calling fcntl(redirector, F_GETFD, 0) in do_redirection() to
find out if a file descriptor is active, do it only if redirector
is not the same as `fd', which you've just opened. This has
spectacularly bad consequences if you do something like
exec 3</dev/tty 4>/tmp/foo 5</dev/null
I'm probably to blame for this, too...
execute_cmd.c
- when saving a file descriptor in add_undo_redirect, make sure we
save the state of the close-on-exec flag, and restore it when
dup2'ing the saved fd back to the orignal.
execute_cmd.c
- when performing a redirection that causes us to open a file, make
sure we at least add an undo record to close the file, even if
the file descriptor is not already active
execute_cmd.c
- when duplicating a file descriptor as the result of a redirection
instruction, make sure to manually duplicate the state of the
close-on-exec flag
11/13
-----
execute_cmd.c
- finally tracked down and stamped out the persistant bug that caused
the shell to hang when doing a command like "history | more" when
there was more than a pipeful of text to send to `more' and you quit
out of `more'after the first screenful. An extra read end of the
pipe was being left open in the shell started to run `history', the
consequence being that that shell at the beginning of the pipeline
would never get the SIGPIPE that would cause it to exit. The fix
is kind of strange: pass around a file descriptor to close whenever
a child process is created in either execute_command_internal or
execute_simple_command. We just pass the file descriptor that we
want closed to the instance of execute_command_internal that runs
the first half of the pipeline, and it gets closed just like we
want.
In the future, this can (and probably should) be made into a bitmap
of file descriptors to close. It wouldn't have to be big, 16 should
be enough given the ability to do close-on-exec.
builtins.c, builtins.c.posix
- changed the one call to execute_command_internal to add the extra
parameter needed by the above fix.
unwind_prot.c
- make without_interrupts() block SIGINT on capable systems (Posix
and systems with BSD sigs) instead of ignoring it, which causes
interrupts to be dropped. Blocking is what you want, anyway.
execute_cmd.c
- add an unwind_protect for the redirections for a function or
builtin. To see why this is needed, define a function shcat:
shcat()
{
while read line
do
echo "$line"
done
}
Now execute "shcat < INSTALL" and try to interrupt it. Bash will
keep reading the lines from INSTALL and trying to execute them
until EOF, at which point the shell exits.
11/14
-----
execute_cmd.c
- a subshell spawned to execute a function or a builtin with a pipe
or an asynchronous function or builtin should have login_shell and
interactive set to 0. That way, if someone is stupid enough to
pipe to `exit' from a login shell, the subshell won't try to exec
.bash_logout.
11/16
-----
builtins.c, builtins.c.posix
- exit status of `type' was wrong for executable files, hashed and
unhashed
bashline.c
- Made bash_complete_filename_internal take just about everything
as a possible filename character. It still can't do completion
of a filename containing blanks if you type one of the blanks,
though -- it needs the blanks-as-word-separators logic to work
at all.

variables.c
- since some places in the code rely on bind_variable returning a
valid value, the dynamic variable assignment functions have been
changed to take a pointer to themselves as the first parameter:
return ((*(entry->assign_func)) (entry, value));
and then return that value after doing whatever they need to

shell.c, execute_cmd.c, shell.h
- shell now exits with status 127 when asked to execute a binary
file as a shell script
builtins.c
- `local' is once again an error outside a function
- `trap' now formats output differently when given no arguments;
the new format is suitable for feeding back to the shell as
input to `trap'
- cleaned up a contradiction in the help text for the `export'
builtin
- `export' and `readonly' now accept a -p flag for Posix.2 compliance
that acts the same as if no flags had been specified, and take a
`--' option to disable further option processing
- `unset' takes a `--' argument to disable further option
processing
- when given the -f flag, unset will now try to unset a variable
if no function is found for the name supplied
- `kill' now takes a -s signal argument as equivalent to -signal
- `kill' takes a `--' argument to disable further option processing,
since a negative number may be used to denote a process group
- `kill -l' now takes arguments and lists the names for individual
signals by number. If the number given as argument is > 128, it
is assumed to be an exit status, and 128 is subtracted before
further processing
builtins.c, variables.c
- `set +' is no more; print_vars_no_values() is no longer needed
flags.c, builtins.c
- `set -C' is now an alias for noclobber
trap.c
- SIGNULL is no longer a valid name for signal 0

builtins.h, builtins/help.def, builtins/mkbuiltins.c
- changed representation of long_doc from a single string to an
array of strings
execute_cmd.c
- only call __setostype() if on isc386 and _POSIX_SOURCE is
defined
general.c
- only define functions for index and rindex if index and rindex
are not already cpp defines
jobs.c
- #undef some things that clash between <sys/ioctl.h> and <termios.h>
on Posix suns
machines.h
- make isc386 machines links with the shared C library explicitly
(-lc_s)
- new entry for a MagicStation (?) from bfox
variables.c
- use a cpp define _CONST_HACK to determine whether the parameter to
getenv() is a char const * (yes for _STDC_, no otherwise)
builtins/type.def
- make found_file local to the block that searches for executable
disk files
11/4
----
execute_cmd.c
- make execute_function_or_builtin use unwind protects to protect
the `return catch' variables
support/getcppsyms.c
- added definitions for M_UNIX, M_XENIX, and _AIX
11/5
----
bashline.c
- fix a call to savestring in command_word_completion_function with
a post-incremented int parameter, since savestring is a macro that
evaluates its argument twice (builtin completion)
lib/glob/fnmatch.c
- add `^' as a character that negates a character class ([])
11/6
----
subst.c
- add a new variable last_command_subst_pid to keep track of the
pid of the last child created for command substitution. Used
to determine whether or not command substitution has taken
place.
execute_cmd.c
- made the exit status of a command that has only assignments and
redirections obey the Posix spec
unwind_prot.c, trap.c
- make sure all sigset_t variables are initialized with sigemptyset
before use
lib/glob/fnmatch.c
- fixed a couple of bugs with [] classes in fnmatch: not checking
whether or not we've hit the ']' and not incrementing the string
argument in the right place
11/7
----
braces.c
- Make backquotes inhibit brace expansion -- defer it until the
subshell runs
- Ditto for $( )
subst.c
- since braces.c now calls unquoted_member and unquoted_substring,
they can no longer be static functions
config.h
- two new configuration options: ALLOW_RIGID_POSIX_COMPLIANCE and
DISABLED_BUILTINS
shell.c, jobs.c
- define and use top_level_signal_mask, restored on longjmps to
top_level by throw_to_top_level
builtins/builtin.def
- use builtin_address to find the function (if so configured) so
that `builtin foo' still works after `enable -n foo'
builtins/common.c
- have both find_shell_builtin, which never finds disabled builtins,
and builtin_address, which does
11/8
----
general.c
- the getdtablesize emulation should ensure that _SC_OPEN_MAX is
defined on Posix systems before trying to use it in a call to
sysconf()
11/10
-----
lib/glob/fnmatch.c
- fixes from Roland McGrath for some of the more egregious bugs
- naturally, Roland missed a few
lib/readline/readline.c
- add missing calls to sigemptyset(), since Posix specifies that
all sigset_t variables be initialized before use using it
- only turn off ISTRIP and INPCK in the termio(s) code if the
character size is 8 bits ((otio.c_cflag & CSIZE) == CS8)
- Sequents running Dynix/ptx should include <sys/pte.h> rather
that <sys/ptem.h>
builtins/type.def
- change a call to printf to builtin_error when printing a
diagnostic that something is not found
builtins/times.def
- changed file inclusion code to include <sys/time.h> and
<sys/resource.h> if HAVE_RESOURCE is defined, then to include
<sys/times.h> if !HAVE_RESOURCE and RUSAGE_SELF is not defined.
This catches systems with deficient <sys/resource.h> files
11/11
-----
lib/readline/readline.c
- Don't try to dereference funmap in rl_named_function() if it's
null (as it is before rl_initialize_funmap is called)
11/12
-----
lib/readline/readline.c
- backed out of change of 11/11 to rl_named_function
bashline.c
- add a state variable bash_readline_initialized to keep track of
whether or not readline has been initialized with a call to
initialize_readline()
builtins/bind.def
- if readline has not been initialized the first time this is
called, call initialize_readline
11/13
-----
execute_cmd.c
- execute_subshell_builtin_or_function would only let the output
of `jobs' be piped if pipe_in and pipe_out were both != NO_PIPE
(?). Obviously a typo.
builtins/command.def
- add an unwind_protect to dispose of the new command created
by the call to make_bare_simple_command
builtins/jobs.def
- add the `jobs -x command args' form from the System V.4 sh
All job specs in `args' are replaced with the appropriate
job's process group id and `command' is executed
builtins/getopt.c
- if getopt() finds that optind > argc when it is called, it
sets optind = argc and returns EOF
builtins/times.def
- backed out of 11/10 change. Some systems, most notably
HP/UX have all the correct includes and defines and simply
do not implement getrusage(). At all.
subst.c
- if sv_optind finds that OPTIND has been unset or set to an
empty string, call getopts_reset (0). The Gnu getopt
resets its internal state when optind == 0.
- call getopts_reset(0) if OPTIND=1, because that's what the
Posix spec says to use to reset
11/14
-----
builtins/alias.def
- fixed a typo in the SHORT_DOC for the unalias builtin
builtins/shift.def
- allowed the shift count to be 0
11/15
-----
lib/readline/readline.c
- turn on 8 bit characters if NO_EIGHT_BIT_CHARACTERS is not
defined and the Posix termios code path is being taken
[The following two entries describe what's needed for an initial
implementation of the vi mode `.' command]
lib/readline/vi_mode.c
- new variables:
vi_last_command: last command that modified text in
the buffer
vi_last_repeat: the repeat count to vi_last_command
vi_last_arg_sign: arg sign for vi_last_repeat
vi_last_motion: the last motion qualifier for the
text modification commands that use one
vi_redoing: state variable, if 1 we're re-doing a
command
vi_textmod: list of commands that modify text
(initially "_*\\AaIiCcDdPpYyRrSsXx~")
- new functions:
rl_vi_redo: an initial implementation of the vi mode
`.' command
rl_vi_set_last: initialize the state of the new variables
described above
rl_vi_textmod_command: return true if command passed is
a text modification command
- changed rl_vi_domove to save the movement command information in
vi_last_motion
- changed rl_vi_movement_mode to call rl_vi_set_last to initialize
the `last command' state
lib/readline/readline.c
- changed rl_dispatch to save vi_last_command, vi_last_repeat,
and vi_last_arg_sign
- changed rl_newline to call vi_set_last
lib/readline/readline.h
- new function rl_vi_redo
lib/readline/vi_keymap.c
- bind rl_vi_redo to `.'
11/20
-----
posixstat.h
- make isc386 defines for S_IFDIR and S_IFMT be used if they
do not already appear, no matter whether or not gcc is being
used for the compile
machines.h
- new entry for Omron Luna 88k running Mach 2.5 (nice machines)
lib/readline/vi_mode.c
- fixed a bug with rl_vi_domove and the last word on the line.
If rl_point ended up > rl_end, it was being set to rl_end - 1
rather than to rl_end.
cpp-Makefile
- quote the values of RANLIB and AR passed to makes in
subdirectories
shell.c
- instead of making all Xenix systems swap the second and third
arguments to setvbuf, make that behavior dependent on the
definition of REVERSED_SETVBUF_ARGS
11/21
-----
lib/readline/readline.c
- fixed an error in rl_forward that caused vi-mode to walk off
the end of the line after executing `l' in command mode on an
empty line
11/22
-----
support/getcppsyms.c
- added the `luna88k' define
11/24
-----
execute_cmd.c
- all calls to dup2 in do_redirection_internal should be checked
for errors and the redirection should fail if the dup2 fails
shell.h, parse.y, execute_cmd.c, print_cmd.c, make_cmd.c
- replaced the single redirection operator `r_duplicating' with
r_duplicating_input and r_duplicating_output to avoid the
read 1<&7 getting printed as read 1>&7 problem:
foo()
{
exec 9</dev/tty
read 1<&9
exec 9<&-
}
is printed wrong when `type foo' is executed
shell.h
- added two new redirection_operators, r_duplicating_input_word and
r_duplicating_output_word to implement true sh semantics for
[n]<&word and [n]>&word
parse.y
- eliminated the old yacc production for >& word, meaning put stdout
and stderr into `word'
- added productions for [n]<&word and [n]>&word that use the new
redirection operators
execute_cmd.c
- the first thing done in do_redirection_internal is now a check for
r_duplicating_input_word and r_duplicating_output_word. If the
redirection is one of those two, `word' is expanded and a new
redirection is made
print_cmd.c
- new code to print the [n]<&word and [n]>&word redirections
(r_duplicating_input_word and r_duplicating_output_word)
make_cmd.c
- new code for make_redirection to handle r_duplicating_input_word
and r_duplicating_output_word
documentation/bash.1
- added documentation for the -x option to `jobs' + minor cleanups
and corrections
11/25
-----
cpp-Makefile
- added GCC_EXTRAS for gcc-specific compiler flags
execute_cmd.c
- removed some unused functions (close_all_files) and variables
(file_exists_p)
parse.y
- added new command-oriented-style history: all lines of a multiple
line command will be added to the same history line
- new variable current_command_line_count to keep track of the
number of lines in the current command. If > 1, a line is appended
to the current history line to implement command-oriented history
- new function bash_add_history
shell.c
- added code to reset current_command_line_count to 0 before calling
parse_command and yyparse
subst.c
- the command-oriented history is controlled by the setting of the
variable command_oriented_history
builtins/reserved.def
- a new help topic: `variables', giving help on some common shell
variables
11/26
-----
lib/glob/glob.c
- if the filename portion of the pathname to be matched is null
(e.g. a*/), do not call glob_vector to attempt to match each
file in the expanded directories against the null string.
11/27
-----
lib/glob/glob.c
- force globbing of directory names even if the metacharacters
contained therein are protected by backslashes. The globbing
strips the quotes correctly
shell.c
- make sure current_command_line_count is declared everywhere
it's used
parse.y
- remove declaration of history_lines_this_session from
pre_process_line
- add extern declaration of history_lines_this_session to
bash_add_history
12/2
----
trap.h
- removed inclusion of <sys/types.h> because most files include it
themselves, and this is dangerous on systems that do not protect
against multiple inclusion of header files
trap.c
- include <sys/types.h> before "trap.h" since it was the only file
in the distribution not to do so
shell.c
- Install the SIGINT sighandler the Posix way on machines with
_POSIX_VERSION defined
12/3
----
dispose_cmd.c
- make sure dispose_redirects properly handles r_duplicating_input_word
and r_duplicating_output_word by freeing the `filename'
execute_cmd.c
- fix do_redirection_internal to copy new_redirect->redirectee.filename
using alloca() so no memory has to be freed at function exit
12/4
----
parse.y
- expand \n in PS1 or PS2 into \r\n only if line editing is enabled
shell.c
- define top_level_mask if _POSIX_VERSION defined
newversion.c
- made it write a definition of SCCSVERSION to version.h -- an SCCS
string so the `what' command will be useful
version.c
- new variable `sccsversion' set to SCCSVERSION
12/5
----
builtins/fc.def
- make fc_gethist check that the history list is non-null before
trying to access its members
12/6
----
lib/readline/readline.c
- changed the ISTRIP code (again) to force bash to disable ISTRIP
only if the tty driver guarantees eight bits (cflag & CSIZE == CS8)
12/9
----
lib/readline/readline.c
- tgetent returns 0 if it can't find the terminal name in /etc/termcap,
so we failed if it returns <= 0, not < 0.
12/11
-----
machines.h
- Sony machines running NEWS-OS 4.0 (V.4) should have strerror(),
so define HAVE_STRERROR
- Pyramids running BSD do not all have the vprintf family of functions,
so remove the definition of HAVE_VPRINTF
12/12
-----
parse.y
- make sure that shell_getc always checks that shell_input_line is
valid before trying to reference shell_input_line[0]
12/13
-----
mailcheck.c
- Since `dollar_underscore' saves the value of $_ in a local variable,
it's possible that bind_variable can free and reallocate the cell
for $_, leaving dollar_underscore pointing at freed storage. The
fix is to copy it into freshly-allocated memory.
- ensure that when saving and restoring dollar_underscore that we do
not try to call strlen on a null string
12/15
-----
general.c, execute_cmd.c
- moved the utility function `all_digits' from execute_cmd.c to
general.c
builtins/kill.def
- remove use of sscanf, used calls to all_digits and atoi instead
machines.h
- if not using gcc, need to make SYSDEP_LDFLAGS = -Xp for Posix
on isc386
12/16
-----
machines.h
- isc386 has multiple groups
execute_cmd.c
- add a QUIT to the while loop in find_user_command_in_path that
searches the path, so users can interrupt a lengthy path search
12/17
-----
builtins/alias.def
- added the Posix-specified -a option to unalias, made unalias obey
the getopt argument syntax guidelines
builtins/jobs.def
- made `jobs' handle the -- option to signal the end of arguments
flags.c
- Posix.2a has specified that the -b flag stand for asynchronous
notification, so move the definition of asynchronous_notification
here and add a new entry to the `flags' struct if JOB_CONTROL is
defined
flags.h
- add an extern declaration of asynchronous_notification
jobs.c
- change the definition of asynchronous_notification to extern, since
it's now declared in flags.c
builtins/set.def
- change documentation strings to add -b option, note that
set -o notify is now the same as set -b
- change the code to make set -o notify the same as set -b
(list_long_opts(), take the special case out of set_minus_o_option)
12/19
-----
lib/readline/readline.c
- added support for $LINES, $COLUMNS. The variables are read after
the ioctl(TIOCGWINSZ) and before calls to tgetent
builtins/fc.def
- made the fc output format correspond to that specified by Posix.2a
("%d\t%s\n")
12/20
-----
execute_cmd.c
- user_command_matches did not properly handle a null $PATH element,
which should be the same as ".". Changed the code to mirror
find_user_command_in_path ()
12/23
-----
execute_cmd.c
- added a new function get_next_path_element, which calls
extract_colon_unit and interprets the result, translating
"" to "."
builtins/cd.def
- added description of -l option to dirs short_doc
- fixed the bug that caused `dirs' to always print an extra
trailing space
documentation/bash.1
- added description of -l option to dirs
parse.y
- added optional leading ( for case clause, as per Posix.2
12/30
-----
lib/readline/vi_mode.c
- removed unused variable `added_blank'
bashline.c
- added dynamic completion from bfox
execute_cmd.c
- redirections must be performed in a child before execution of
the command is attempted or aborted (because it's not found
by a hash table or $PATH search), according to Posix.2
getcwd.c
- new file, from the Gnu C library, for systems that don't do
this right -- they use popen("/bin/pwd", "r") instead
12/31
-----
builtins/type.def
- the type builtin would not report a name as not found if any name
had previously been found because the flag variable used to report
this (found_something) was not reset each time through the loop.
Added a variable `found_any' to be global and reset found_something
to 0 each time through the loop
1/4
---
builtins/jobs.def
- make sure that the call to add_unwind_protect in
execute_list_with_replacements is made after the new command
struct is completely initialized
support/mksysdefs
- look for /dev/fd, define HAVE_DEV_FD if present
cpp-Makefile
- pass HAVE_DEV_FD through to make in SYSTEM_FLAGS
shell.c, execute_cmd.c
- call unlink_fifo_list only if HAVE_DEV_FD is not defined and
PROCESS_SUBSTITUTION is defined
subst.c
- new function make_dev_fd_filename to return /dev/fd/xx, where
xx corresponds to the parent end of the pipe
- all the named pipe utility functions should be #if !defined
(HAVE_DEV_FD)
- change process_subsitute to do the following on systems with /dev/fd:
1. Make a pipe in the parent
2. if (open_for_read_in_child)
parent_pipe_fd = fildes[1]
child_pipe_fd = fildes[0]
else
parent_pipe_fd = fildes[0]
child_pipe_fd = fildes[1]
3. pathname = make_dev_fd_filename (parent_pipe_fd);
4. fork
5. In parent, close child_pipe_fd and return pathname
6. In child, turn off job control, dup child_pipe_fd to
either fd 0 or 1 depending on OPEN_FOR_READ_IN_CHILD,
close parent_pipe_fd, parse and execute the string,
and exit
shell.c
- added call to unlink_fifo_list in reader_loop so that all fifos
get closed, even after builtin commands are executed

nojobs.c
- Posix systems now reap zombie children and retry a fork() once if

- Posix systems should use waitpid() rather than wait() wherever
possible
- Posix systems do not need to validate a pid before calling waitpid()
in wait_for_single_pid(); waitpid takes a pid argument

execute_cmd.c
- fixed extract_colon_unit to return "" in the case of a trailing
colon in the path
INSTALL
- note that on SCO Xenix 386 one must use cc -E rather than /lib/cpp
to process cpp-Makefile
cpp-Makefile
- fixed the problem of a single quote in a makefile comment
machines.h
- Xenix 386 machines need -DUSG in SYSDEP_CFLAGS
lib/readline/readline.c
- changed the includes around so that the Xenix 386 support is
in the same section as the USGr3 code, and the Xenix 286
support is in the same section as the plain USG code
shell.c
- split the `int code = setjmp (top_level)' statement in
reader_loop into two statements -- some compilers don't like
it
parse.y
- changed the overloaded `yy_input_dev' to a `union STREAM',
where a `union STREAM' is
typedef union STREAM {
FILE *s_file;
char *s_string;
} STREAM;
and changed the parameter to init_yy_io and all the functions
that call it to use a STREAM argument instead of casting back
and forth between a (char *) and a (FILE *)
builtins/times.def
- If hpux or USGr4, #undef HAVE_RESOURCE, rather than try to fit
all the special cases onto a single line deciding whether or
not to include <sys/resource.h>

bashline.c
- changed the bindable name for the ksh-style ^O function from
operate_and_get_next to operate-and-get-next
execute_cmd.c
- some systems (e.g SGI) allow the result of alloca to be assigned
only to a `simple' variable, so I introduced a dummy one instead
of assigning to redirectee->word directly
shell.c
- fixed a typo: PENDANTIC -> PEDANTIC
machines.h
- took -DREVERESED_SETVBUF_ARGS out of the entries for Xenix 386
cpp-Makefile
- added double quotes around the RHS of the assignment to
SYSTEM_NAME to avoid further cpp processing if the system name
happens to be a cpp define

builtins/read.def
- Fixed read to treat backslash as an escape character unless
-r is given, as per Posix.2
lib/readline/readline.c
- Fixed up the maze of dire[cn]t includes and defines so that
they're correct for Xenix (finally)
lib/glob/glob.c
- ditto. Now the defines/includes are correct for Xenix 386
execute_cmd.c
- a loop of the form
while : ; do echo -n 1; done
can run a machine using Gwyn's alloca() emulation out of memory
because alloca() keeps getting called at the same stack level
and never frees anything up. Added a call to alloca(0) after
the call to execute_simple_command in execute_command_internal
- added Karl Kleinpaste's workaround for the AFS file creation
bug, dependent on AFS_CREAT_BUG
parse.y

machines.h
- M_MACHINE is now `hppa' for HP Precision Architecture machines, so
to make sure hpux is defined, it's now in SYSDEP_CFLAGS
- Make sure that the RS6000/AIXv3 description defines M_OS as AIX,
not "AIX". The quotes are added in cpp-Makefile

- move the initialization of PWD before the environment is read, so
an exported version of PWD takes precedence
readline.c, funmap.c, emacs_keymap.c

This is a description of the changes made to bash for increased ksh
compatibility.
1. $SECONDS
"Each time this parameter is referenced, the number of seconds
since shell invocation is returned. If this parameter is assigned
a value, then the value returned will be the value that was
assigned plus the number of seconds since the assignment."
Files changed: variables.c
variables.h
subst.c
general.c
shell.c
general.h
2. $TMOUT
"If set to a value greater than 0, the shell will terminate if a
command is not entered within the prescribed number of seconds
after issuing the PS1 prompt."
Files changed: shell.c (the implementation is not perfect)
3. $RANDOM
"Each time this parameter is referenced, a random integer is
generated. The sequence of random numbers can be initialized
by assigning a numeric value to RANDOM."
Files changed: subst.c
variables.c
4. $REPLY
"This parameter is set by the `read' special command when no
arguments are supplied."
Files changed: builtins.c
5. integer variables
`declare -i' (also export) makes a variable an integer (turns on
the integer attribute). When assignment is made to a variable with
the -i attribute, arithmetic expression evaluation is done on the
value before it is assigned to the variable.
Files changed: variables.h
variables.c
builtins.c
6. Arithmetic expression evaluation.
Here is the comment at the beginning of the new file `expr.c':
ksh-style expression evaluation.
All arithmetic is done as long integers with no checking for overflow
(though division by 0 is caught and flagged as an error).
The following operators are handled, grouped into a set of levels in
order of decreasing precedence.
"-" [level 0 (unary negation)]
"!" [level 1]
"*", "/", "%" [level 2]
"+", "-" [level 3]
"<=", ">=", "<", ">" [level 4]
"==", "!=" [level 5]
"=" [level 6 (assignment)]
(Note that most of these operators have special meaning to bash, and an
entire expression should be quoted, e.g. "a=$a+1" or "a=a+1" to ensure
that it is passed intact to the evaluator).
Sub-expressions within parentheses have a precedence level greater than
all of the above levels and are evaluated first. Within a single prece-
dence group, evaluation is left-to-right, except for the arithmetic
assignment operator (`='), which is evaluated right-to-left (as in C).
The expression evaluator returns the value of the expression (assignment
statements have as a value what is returned by the RHS). The `let'
builtin, on the other hand, returns 0 if the last expression evaluates to
a non-zero, and 1 otherwise.
Implementation is a recursive-descent parser.
Files added: expr.c
7. `let' builtin
Parameters may be assigned numeric values via the `let' builtin.
Each of its arguments is an expression to be evaluated. `let'
returns 0 if the value of the last expression is non-zero, and
1 otherwise.
Note that the "((...))" form of this command has not yet been
implemented; it requires changes to the parsing functions.
Files changed: builtins.c
8. $_
$_ is set to the last argument of the previous command line, after
expansion. It is still used as before when checking for mail.
Two new keybindings have been added to insert this into the current
command line (M-_ and M-.).
Files changed: mailcheck.c
execute_cmd.c
bashline.c
9. `cd -'
Equivalent to 'cd $OLDPWD'
Files changed: builtins.c
10. "ulimit -a"
"List all of the current resource limits (BSD only)."
Files changed: builtins.c
11. ${#@} and ${#*}
These expand to the number of positional parameters.
Files changed: subst.c

This file details the changes between the previous release of CWRU bash
(07/11/93) and this release.
1. Bugs Fixed
Readline's vi-mode once again has TAB bound to completion; entering `posix
mode' changes it to self-insert
Bash now binds its special emacs-mode functions directly into
emacs_meta_keymap so that eight-bit character handling does not interfere
Some source restructuring: more extern functions are defined in header files
and not in C source files
The handling of `line number' inside functions is now more correct and
closer to reality
Some functions of `general use' were moved to general.c (vfree,
full_pathname)
A bug that caused some redirections to be applied twice was fixed in
execute_command_internal (dispose of redirection_undo_list after copying it;
ditto for exec_redirection_undo_list)
The exit status of a command that is not found is 126, as Posix.2 specifies
More speed improvements -- bash now runs as fast as the SunOS sh on
Haertel's `shell benchmark'
Instead of returning pointers to -1, bash and the readline, history, and
glob libraries now return pointers to special `error pointers', which the
calling code checks for in place of -1
Fixed a problem with canonicalize_pathname which made it get
confused with xxx/./yyy if yyy was `.' or `..'
Fixes to make bash recognize SVR4.2 and set USGr4_2 for SVR4.2 systems
Fixes to the HP/UX machine descriptions to make alloca work on HPUX_9
and to avoid `M_MACHINE redefined' warnings
Fixes to the CRAY machine description
Fixes to the mailpath code to make it Posix.2-compliant -- backslash
may now quote `%' and `?'
The namespace was further cleaned up, and more functions and variables
were made static
On systems with S_IFSOCK or S_ISSOCK defined in sys/stat.h, bash checks
whether fd 0 is a socket to decide whether or not it's being started by
rshd and to run the startup files
Bash now gives the signal mask it inherits to its children -- previously,
login shells cleared the signal mask
cpp-Makefile and subst.c both used the `USE_GLOB_LIBRARY' define, but
with different meanings; subst.c now uses `USE_POSIX_GLOB_LIBRARY'
Fixed pattern substitution so that ${a%%$b}, where b was unset, no longer
causes a core dump
Changed the `test_exit' define in test.c to no longer use `longjmp' as
the rhs or a comma-ized expression; this causes core dumps on some
optimizer/machine combinations
A speed hack in variables.c: if no local variables are defined for a level
of shell context, kill_all_local_variables does not need to search the
whole variable hash table when popping a context
Fixed the `bind' builtin so that -m now changes the keymap for all of the
subsequent operations
Changed some more builtins to use internal_getopt: bind, command, export,
readonly, declare, typeset
Fixed fc to use the Posix.2 format for listing commands in the
history list
Changed bg to set `!', as Posix.2 specifies
Fixed ulimit.def to compile if RLIMIT_RSS is not defined,
as some systems seem to have it
Replaced lib/malloc/alloca.c with the version from emacs 19. The old one
lives in alloca.c.old
malloc.c now uses the ANSI C features to `stringize' macro arguments if
__STDC__ is defined
Fixes to the GNU malloc library from glibc 1.06 and Mike Haertel
Fixes to readline key binding and lookup for Cray systems, which don't
like the casting that readline does
Fixes to all readline library source files to clean up the code: make sure
`int'-returning functions use `return x;' rather than `return;', declare all
arguments, even the `int' ones, and make some functions void. Cleaned up
the code formatting a little, too.
The readline completer now double-quotes filenames with special word-break
characters, so that tilde expansion still works
^C now breaks out of keyboard macros
If being compiled as part of the shell, readline no longer attempts to
handle SIGTTIN, SIGTTOU, or SIGTSTP
tilde_expansion_failure_hook is now a CPFunction rather than a Function,
since that's how it's used
Readline vi-mode `change case' function now skips over characters which
are neither upper nor lower case
Readline vi-mode now allows replacement to be redoable with `.'
2. New Features
A `strict Posix.2' mode, enabled with the -posix startup option or
setting the POSIXLY_CORRECT variable (see CWRU/POSIX.NOTES for a
description of the changed behavior)
`ONESHOT' is now an option in config.h
cpp-Makefile assumes that fixed header files are present if gcc is being
used
