Make ulimit able to get and set multiple limits in a single invocation
like bash and zsh do. Requested by espie@, OK deraadt@
matches mksh pre-R29 (the one introducing the bug), and typeset matches
the behaviour intended with the R29 changes (better AT&T ksh93 compati-
bility) but never reached
• adjust the man page description of “typeset -p”, as it’s different from
the “typeset” and “typeset -” actions
• apply diff from mirbsdksh-1.11:
#ifdef DUP2_BROKEN
/* Ultrix systems like to preserve the close-on-exec flag */
‣ XXX we do #ifdef __ultrix here (imake-style) instead of mirtoconfing it
(but does anyone know of any other OS with the same problem? plus we’d
see it as we now know the symptoms)
• remove ultrix Build.hs warn=' but might work…' in the hope it DOES
• split Xinit into XinitN and Xinit macro, the former
not initialising the “xp” argument of the latter,
and use this to get rid of two variables that are
only assigned but never referenced (gcc doesn’t see
this, but MIPSpro and IIRC SUNWcc do)
• re-indent while here
• bump patchlevel
‣ I/O redirection seems broken:
$ (date; date >/dev/null; date) | wc -l
1 (expected: 2)
‣ other than that: working fine
‣ -YBSD (default) and -YSYSTEM_FIVE don’t work, just -YPOSIX, somehow
• Fix $(…) to `…` for OSF/1 V2.0 /bin/sh
‣ this compiler is FUBAR though:
$ cat >t.c
main() { return (foo()); }
$ cc t.c
ld:
Unresolved :
foo
$ echo $?
0
$ ls -l a.out
-rwxr-xr-x 1 mirbsd users 10835 Jul 21 17:12 a.out
‣ it seems to have ucode, but man is not installed
• new mirtoconf check: mkstemp(3)
• if !HAVE_MKSTEMP (Ultrix), use tempnam(3)
• only use printf(1) if it exists (it doesn’t on Ultrix)
• a few more signals
• add S_ISLNK if the OS doesn’t define it
• add strcasecmp(3) proto for Ultrix (it _is_ in <portability.h>, but
only for -YBSD I think)
• fgrep(1) on Ultrix doesn’t do “-e ① -e ②”

• the platform’s sig_t is incompatible too (simplify check)
• no compile warnings at all
• results in:

• minor testsuite issues:
FAIL ./check.t:regression-13
unexpected stderr - got too much output
wanted nothing
got:
Successful
cat: output error
⇒ probably harmless
• works like a charm!
the token. Fixes unreported problem with pdksh reporting syntax error
on the init scripts that define function named ‘stop’ (clashing
with an built-in alias.)

this change broke abortion on failure to read input, was not
needed for gcc warnings and is the fault of Intel’s compiler
this should fix the other busy-loop problem occuring only on
GNU/Linux so far – 10x spaetzle@freewrt.o for pointing me to
the problem; reproduced on my work craptop
from netbsd via oksh
we had the NULL pointer deref already fixed
• avoid a bogus not-setting the return value of edit.c:x_file_glob()
introduced by the above change in oksh
• escape ? as well (but not ] because that’s wrong)
reminded by cbiere@netbsd via oksh
• Unsetting a non-existent variable is not an error. See
http://www.opengroup.org/onlinepubs/009695399/utilities/unset.html
report from Arkadiusz Miskiewicz; fixed based on
http://cvs.pld-linux.org diff via oksh but modified slightly
• Be more smart waiting for input for non-interactive scripts. Fix
based on a diff from debian: see their bug#296446 (via oksh)
modified slightly
this also fixes cnuke@’s “mksh busy loop” problem, for which I never
received a bug report, but the Debian bug page contains a set of two
scripts to reproduce this before (and no longer after) this commit
• some KNF
• bump version
In contrast to AT&T ksh93, its semantics are like GNU bash in that it ap-
pends the current working directory to the search path; it is implemented
as a shell alias instead of enhancing funcs.c:shbuiltins[] like in ksh93.
delivered to the process
• regression test by Clint Pachl, verified against Debian ksh93 by me
• place to fix it in the code discovered by Otto Moerbeek
