Yeah, but didn't you guys produce Neil Lomax (lo these many years ago)? What
have the other schools given the NFL lately?

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.
Yours sincerely,

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

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).
Thanks,

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

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.

subst.c
- when doing command substitution, strip only the trailing newlines.
This is in accordance with Posix.2.
general.c
- strip_trailing () has aquired a new flag telling whether to strip
all white space or just trailing newlines.
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

- 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
1/6
---
machines.h, make_cmd.c, print_cmd.c, shell.c, cpp-Makefile
- HAVE_VPRINTF --> HAVE_VFPRINTF
cpp-Makefile, machines.h, test.c
- HAVE_MULTIPLE_GROUPS --> HAVE_GETGROUPS
cpp-Makefile, machines.h
- HAVE_SIGLIST --> HAVE_SYS_SIGLIST
parse.y
- add if_command production
builtins/echo.def
- validate all arguments before using them so that -nanything != -n
- document the -E option and its use
builtins/umask.def
- allow other arguments to be used with -S
subst.c
- make sure to close all files in the child created to run a
process substutition to avoid holding write file descriptors
to pipes that will cause the shell to hang
1/7
---
cpp-Makefile
- fixed a typo: SEARCHLIB -> SEARCH_LIB
machines.h
- new description for Amiga 3000 running System V.4
shell.c
- default secondary prompt is now "> "
builtins/bashgetopt.c
- more internal cleanups and bug fixes
support/mksysdefs
- detect the amiga by the presence of /usr/amiga
1/9
---
general.c
- canonicalize_pathname should remove ./ only if it's at the
beginning of the pathname, or immediately preceded by a `/'
1/10
----
documentation/bash.1
- clean up the documentation for test -t, since according to
Posix, it always requires an argument
general.c
- don't build index and rindex for DG machines
machines.h
- description for System V.4 on IBM 370 architecture
- fixed up DG/UX machine description

[ Work begins after network release of version 1.11 ]

----
nojobs.c
- Posix systems now reap zombie children and retry a fork() once if
it fails
- 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
1/13
----
execute_cmd.c
- get_next_path_element can return NULL, so the code that calls it
must take that possibility into account
jobs.c
- there was an extra parameter in the select() call
builtins/type.def
- successful_finds needed to be initialized to 0
machines.h
- fixed a typo (_D -> -D) in the DG/UX machine description
1/14
----
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>
1/15
----
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
bashline.c
- added `search-forward', `search-backward' functions that perform
non-incremental history searches using the vi-mode code
1/16
----
builtins/ulimit.def
- fixed a typo in a comment
- added parens around the object in an #if defined preprocessor
statement
machines.h
- the Xenix 386 machine descriptions need to #undef HAVE_GETWD
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
- \s in a prompt string needs to decode to the shell basename, as
per the documentation, rather than the full shell name
1/17

nojobs.c
- fixed a typo in one of the WAITPID calls, thanks to Bruce Evans
[At this point, all of these fixes were sent along to bfox]
support/getcppsyms.c
- now recognizes cpp symbol __hppa for use on HP precision
architecture machines
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
1/27

parser.h
- new file, contains structures necessary to parse commands
input.h
- new file, contains definitions and structures used to read input
bashline.c

error.c, error.h
- new files to isolate the error-handling functions
command.h
- new file including structures used internally to represent
commands

- include input.h, parser.h
- changed all the code that deals with input streams to fit the
new framework defined in input.h
make_cmd.c
- moved the error reporting code to error.c

shell.h
- removed the code that was moved to input.h, parser.h, command.h
builtins/common.c
- moved a call to setjmp out of an if statement
- changed the input code to work with the new input framework
builtins/getopt.c
-include config.h if compiling for the shell
lib/readline/readline.c
- change representation of characters > 127 to octal
rather than M-c
- changed representation of characters < ' ' to ^X rather
than C-x
- fixed a memory leak in parser_if () by freeing `tname'
machines.h
- removed MIPS_CFLAGS from the ultrix Decstation entry, since the
limit no longer needs increasing
variables.c
- 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
- removed support for rl_arrow_keys -- it should now be done by the
inputrc file
documentation/bash.1
- only non-job-control shells start background jobs ignoring SIGINT
and SIGQUIT
builtins/umask.def
- don't print the octal representation of the umask if the symbolic
representation has already been displayed
- a bad option to umask should return EXECUTION_FAILURE, not -1
shell.c
- new function, init_signal_handler (sig), to initialize the SIG
signal hander, call it in main loop
nojobs.c
- call init_signal_handler (SIGINT, sigint_sighandler) so the correct
thing happens on Posix systems
general.c
- updated the comment above the fallback implemenation of killpg()
machines.h
- machine entry for the Unix PC
- new variable HAVE_DIRENT
1/28

machines.h
- SCO needs to #undef HAVE_GETCWD so that the getcwd() function
supplied with bash is used
subst.c
- USG machines should include <string.h>, others <strings.h>

sprintf
builtins/ulimit.def
- changed the resource limit struct to one that has no explicit
size to account for systems with differing numbers of resource

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
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 is a description of the changes made to bash to provide a `restricted'
shell, `rbash', organized by changes to various source files.
1. shell.c
Moved the declaration of restricted to flags.c; it is now declared
extern here. Changed the detection of a restricted shell; now, any
instance of the shell for which *(basename(argv[0])) == 'r' (where
basename returns either everything after the last '/' in its
argument or its argument is restricted. Also, if SHELL is set on
entry to the shell, and it's basename is "rbash", the shell is
restricted.
This paragraph applies only to CWRU, or to those who have compiled
the shell with "CWRU" defined. When a shell is determined to be
restricted, and it is a login shell, the file "/etc/rprofile" (and
only that file) is executed. There is no execution of ~/.profile
or ~/.bash_profile. The .bashrc file is executed, but after the
restrictions have been turned on (users may customize their instances
of the shell in this file while not compromising any kind of security
arrangements set up by the administrator).
2. builtins.c
cd_builtin was modified to return failure if bash is operating in
`restricted mode', so changing directories is not allowed.
3. variables.c
initialize_shell_variables () was modified to make PATH and SHELL
read-only when restricted == 1. These variables may not be unset
in a restricted shell.
4. flags.c
The variable `restricted' is now declared here. A new flag `-r',
to turn on restricted mode, has been added. `change_flag' has
been modified to disallow `set +r' if restricted == 1.
5. execute_cmd.c
execute_simple_command () was modified to disallow commands and
file names that contain a slash.
Code was added to do_redirections () and do_redirection() to
disallow output file redirection specifications if restricted is
1.

@@ -1,53 +0,0 @@
This describes how bash users create, destroy, assign, and reference array
variables. Array variables are variables whose values are arrays of strings,
and whose elements may be referenced individually.
CREATING
- any variable may be declared as an array using `typeset -a'
- an ordinary variable may be converted to an array using
`typeset -a'; the value becomes array[0]
- there is a question of notation used to simultaneously declare
an array variable and populate it with values sequentially,
like ksh does with `set -A'. `set -A' is a horrible choice;
it should be discarded immediately.
- we can use `typeset -a array [values...]'
DESTROYING
- `unset name' will destroy the array `name'
- how to treat `typeset +a array'?
- I think we should keep the variable, convert it from an
array to an `ordinary' variable, and make the value at
the smallest index of the array the value of the new
variable
ASSIGNING
- array[index]=value will serve to assign values to individual
elements of the array
- the subscript can be an arbitrary arithmetic expression; it
will be run through the expression evaluator
- this can create arrays, too
- this is analogous to defining a variable by simply
assigning to it
REFERENCING
- $array will expand to all elements of the array, just like $*
expands to all the positional parameters
- "$array" is like "$@"
- ${array[index]} is used to reference array element `index', where
`index' can be an arbitrary arithmetic expression
- two special values for `index': * and @ expand to all
elements of the array, just like $* and $@. Quoting
behavior is the same, too
- using a subscript is an error if a variable has not been declared
as an array (is this wise?)
- ${#variable}, if `variable' is an array, expands to the number of
elements in the array
- ${#variable[n]} expands to the length of variable[n]. n
may be an arbitrary arithmetic expression
- ${#variable[*]} and ${#variable[@]} expand to the number of
elements in the array
OPEN QUESTIONS
- should we allow them to be exported? Ksh does not, but rc does

$SHORT_DOC histctl [-cC] [-iI space|dups|both|none]
Control how lines are saved into the command history. An option
of -c enables command-oriented history, in which all lines of a
compound command are saved as a single history entry. The -i
option permits certain lines to be discarded without being stored
in the history: SPACE means to ignore lines beginning with a space;
DUPS means to ignore lines the same as the last command entered
into the history; BOTH enables SPACE and DUPS; and NONE means to
store all lines.

$SHORT_DOC read [-r] [-p prompt] [-a array] [name ...]
One line is read from the standard input, and the first word is
assigned to the first NAME, the second word to the second NAME, etc.
with leftover words assigned to the last NAME. Only the characters
found in $IFS are recognized as word delimiters. The return code is
zero, unless end-of-file is encountered. If the -r option is given,
this signifies `raw' input, and backslash processing is disabled. If
the `-p' option is supplied, the string supplied as an argument is
output without a trailing newline before attempting to read. If -a
is supplied, the words read are assigned to sequential indices of ARRAY,
starting at zero.
