cgd edc0ef345c Fix growstackblock() 'newlen' calculations:
(1) it needs to be ALIGNed for both halves of the 'if,' and
	(2) if you're going to claim that you now have ALIGN(newlen)
	    bytes left, you should have actually allocated
	    ALIGN(newlen), rather than just 'newlen' bytes.

* Make sure it's rebuilt if a .h file is updated.
From Mike Long, PR 1454.

christos d3aec2060d Fix PR/2070: Ksh style variable modifiers were broken in /bin/sh, from
enami tsugutomo
1996-02-12 15:11:41 +00:00
christos ff008dabf6 Fix PR/1760, where 'cd -' before any other command could cause a reference
to an uninitialized pointer. Use getcwd() to get the current working directory,
instead of forking /bin/pwd [per Scott's suggestion]

christos c22dddc4e0 Parallel make fixes. 1995-10-22 00:15:02 +00:00
christos 893ade3fac - fix PR1620, -DNO_HISTORY did not work.
- restore parsing state after parsing old style command substitution.
  The ';' in '`echo z;`' broke the following:
	for i in 1; do
		cat > /dev/tty << __EOF__
		`echo z;`
		__EOF__
	done

cVS: Enter Log.  Lines beginning with `CVS: ' are removed automatically

christos c1b02d9bff - Fix -v flag, so that it works properly when the shell reads from scripts.
- Bad style to fix my own PR, but I'd like to commit the parallel make
  changes soon, and this is a necessary prerequisite.

jtc d4fe82df8d Handle %q format directive; from Mike Long (PR #1454). 1995-09-14 16:19:06 +00:00
christos f9382bca1a Fix return builtin to work like it does in ksh:
When not in a function, it skips the rest of the current input file.
Instances of `return' outside function definitions were previously ignored.
What does joe posix have to say about this?
[fixes PR/1444]

christos 782cb68126 Fix bin/1240, from Dennis Ferguson. the exit builtin with no arguments

Eliminated unneccessary conditional.

christos a45947b2a4 Changed so that 'PATH=newpath command' works, instead of looking at the
old path. Synced input.c with vangogh.

cgd dcb82cbdbc needs string.h 1995-06-07 16:28:03 +00:00
christos 9d255ec409 Ignore result of sigaction when setting traps. Traps will succeed even
on SIGKILL or SIGSTOP. This is what other bourne shells do. (suggested
by mycroft)
1995-06-07 04:16:57 +00:00
christos b842cc2784 Avoid trapping SIGKILL. Pretend that we did, so that we will not keep
failing trying to trap it later. This is what the other bourne shells do.
1995-06-05 14:24:33 +00:00
christos 58e18fc330 Fixed bug where
$ cat foo
echo $FOO

$ FOO=1 . ./foo
$ echo $FOO

Did not echo 1 at all. Now variable assignments before sourced scripts
are honored during and after the execution of the script.
1995-05-28 18:09:48 +00:00
christos 4fb6f609aa Changed so that syntax errors (EXERROR) set the exit status to 2,
and commands that are not found set the exit status to 1 like all
other bourne shells.
[It used to be 0 and 2 respectively]
1995-05-19 15:08:55 +00:00
christos 56a08eccca Fixed bug where ${#} was interpreted incorrectly as ${#var} and thus
misparsed. Keith Bostic reported it.
1995-05-17 00:05:25 +00:00
cgd b5f33fc18e re-add an #endif that was (apprently) clobbered. 1995-05-15 03:29:54 +00:00
christos fbac2e9de2 Fixed new bug the previous fix introduced:
false
    foo=bar
    echo $?

would print 1
Also fixed the long standing bug:

    false
    echo `echo $?`

would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient
1995-05-15 02:47:38 +00:00
christos 2e1970487e Fixed bug caused by previous x=`false` not preserving the exit status fix.
The if statement exit status broke...

christos 07bae7eddd Merge in my changes from vangogh, and fix the x=`false`; echo $? == 0
bug.

christos df504509f1 1. Don't core dump on 'fc -l' (From Gerard J van der Grinten)
2. PATH=xxx ls, does the PATH assignment first and then tries to find ls in xxx
3. VAR=xxx exec ls, does the variable assignment.
1995-03-31 21:58:09 +00:00
christos 6ee2193d9a Reverted to set - turning off -x and -v. Charles corrected me... It is part
of POSIX.
1995-03-26 17:25:10 +00:00
christos ad1f891148 set -
does not anymore clear the -x and -v flags. This was incompatible with
all other bourne shell implementations.

christos 5c42185b5c Oops... typo in the IFS previous fix. 1995-02-28 23:27:24 +00:00
christos 6ab1954578 Changed so that backquote expansion eats all trailing newlines, not just
the last one.
Reported by guido@gvr.win.tue.nl (Guido van Rooij).
Repeat By:

	echo "`cat file-with-many-newlines`"
1995-02-28 23:09:43 +00:00
christos 3936aab031 Changed IFS string-splitting so that it breaks spaces even when IFS does not
begin with a space, but contains one. Fixes PR bin/809.

        #!/bin/sh
        list="a  b c "
        echo "With ordinary IFS"
        for i in $list;do
            echo $i
        done
        IFS=":${IFS}"
        echo "With changed IFS"
        for i in $list;do
            echo $i
        done

Note that before the fix ":${IFS}" behaved differently than "${IFS}:".
