ahoka 776cc76ccb Add check for the nice(3) system call.
It may be not implemented on some plaforms, though it's usually present.

Required to compile on Haiku as of 2008 October.

tg 72f9cf1c9b optimise based upon the following assumption:
• my_pid = getpid(); setpgid(0, my_pid);
• if it hasn’t failed, the following is true: getpgrp() == my_pid

at least this is what I gather from TFM and the kernel source
waldi _thinks_ so, too

tg f17b8b1c8b • alloc() can’t fail, afree() can take NULL
‣ macro afreechk() is superfluous
• get rid of macro afreechv() by re-doing the “don’t leak that much” code
• some KNF (mostly, whitespace and 80c) while here

tg 6be5205b36 mksh:
* initialise the integers PPID, OPTIND, RANDOM, SECONDS, and TMOUT to base-10
* bring back PGRP as base-10 integer to the process group via getpgrp(2)
* initialise USER_ID as base-10 integer to the effective user id as retrieved
  from geteuid(2) = $(id -u)
* use $USER_ID in dot.mkshrc instead of spawning an id(1) process
  -> dot.mkshrc,v 1.34 now requires mksh R34
* convert more int to bool where appropriate
* remove dead code - getpgrp(2) cannot fail
* sync manual page to reality
* bump to mksh R34(beta) - feature freeze

XXX check if our_pgrp in jobs.c is still really needed, the setpgid call
XXX probably just makes us our own pgrp leader, and we might have to use
XXX and update kshpgrp accordingly - need feedback/help here but I think
XXX this simplification should be possible if I grok the code correctly.

etc/profile:
* adjust to $USER_ID changes in mksh (speed-up here, too)

mksh.hts:
* sync changelog

tg c1c939e340 • fix memory leaks found by coverity
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

tg 81014fa81b more errno cleanup 2007-06-06 23:41:24 +00:00
tg 3dcf22a319 ok, icc _did_ track down a few ones, and I fixed errno abuse a little too
however, bad S/N ratio

side effect bonus: smaller code size now

tg 0989f7da67 Fix for Coverity CID#2: false bug, but still a problem.
Analysis:
internal_errorf(int, fmt, ...) was only a __dead function if the int argument
was non-0, which the Prevent probably was unable to follow. Change all uses of
internal_errorf(0, fmt, ...) to internal_warningf(fmt, ...); change the pro-
totype of internal_errorf() to internal_errorf(fmt, ...) and all remaining
uses remove the non-0 int argument; add __dead to internal_errorf() proto;
flesh out guts of internal_errorf() and internal_warningf() into a new local
function for optimisation purposes.

Some whitespace cleanup and dead code removal (return after internal_errorf(1))

tg 83c2ee87f4 • remove strcasestr.c, use home-grown implementation¹, call it stricmp,
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
  that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
  only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
  to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version

¹) side effect from creating API-correct cstrchr, cstrstr, etc.
   uses goto so it must be better ☻

tested on mirbsd-current via both Makefile and Build.sh

tg 87f681b488 * revert some of the const-warning cleanup which must be done
with different means (reads, tricky magical kludgery)

tg 5891915f1b * Scan for __attribute__((...)) in general (the earliest was 2.5,
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
  if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
  scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more

tg 56ffbf7e70 hand-sorted ctypes/chtypes upgrade; use table-driven where they make
sense and preprocessored otherwise; unify the logic
saves 144t 1i and lots of cpp(1) time, as well as improves readability

tg a1ff719ba4 thanks to the nice property of my reimplementation of getn to also
return a value in case of an error (0 or the partial result, which
is the full result in case of trailing junk even), using it to rid
atoi() is possible, saving 9t 4d 1i

tg 7672b9b346 apply some fixes from OpenBSD and don't apply some others
but sync RCS IDs for easier future adaption:
* Simplify savefd() by removing the "noclose" flag and make noclose
  behavior the default. Almost all uses of savefd() are followed
  by an implicit or explicit close.
* fix typos
* might as well make ksh_getopt() match real getopt(), ie. get rid of that
  stupid EOF concept that was never true. adobriyan@gmail
* use SEEK_* for lseek()
* fix lint comments, no functional changes
* remove excessive optimization; from adobriyan@gmail
* only santa checks things twice; from adobriyan@gmail
* Interpret zero-filled numbers as decimal; PR 4213; from Alexey Dobriyan

bsiegert 62575b6338 Move <sys/time.h> include to the top. Unbreaks mksh compilation on Darwin,
where <sys/resource.h> contains several struct timeval references, but this
struct is only defined in <sys/time.h>.

tg 16fb264efc aaaand: Interix. 2005-05-23 16:23:19 +00:00
tg cd7b8bd79b Add mirbsdksh R21, which was developed in a temporary external CVS repo-
sitory whose ChangeLog follows. mksh R21 is licenced under the MirOS li-
cence, shown in "sh.h", and a two-clause UCB-style licence by Marc Espie
as shown in "alloc.c".

This executable is a fair bit smaller and shorter than our /bin/ksh that
it is designed to eventually replace (as /bin/sh hardlink), with the old
/bin/ksh to completely vanish. It is still in beta testing though, and I
don't think it will compile on other operating systems.

mksh R21 is a completely new port, bringing together the OpenBSD-current
/bin/ksh, the MirOS-current /bin/ksh and the older mksh R20 (which still
was portable, ocvs-based).

* remove /usr/include/{,open}ssl upgrade workaround from includes/Makefile
* nuke old bin/ksh
* nuke libexpat and xmlwf

tg f6e24ec417 Our times(3) just calls getrusage(2) and gettimeofday(2), converting seconds
to ticks.  Since ksh needs things in seconds it then converted them back.
Avoid the silliness and use the getrusage(2) and gettimeofday(2) directly.
