tg 16c47bbe91 fix bug exhibited by t0000-basic.sh introduced in R38 shortly before the
release: sometimes, a “cd -P” would cause memory corruption because lalloc
internal data was overwritten due to accidentally losing a “continue;”
2009-05-31 15:10:07 +00:00
tg b90007d784 • Build.sh, strlcpy.c: gcc-current conversion &c. warnings cleanup
• histrap.c, lex.c, misc.c: get average stack frame size to <= 768 bytes
• check.t, sh.h: bump version
2009-05-27 09:58:24 +00:00
tg b6ce748064 • remove “#if 0” and “#ifdef notdef” style old debugging code
• expose “#ifdef MKSH_MIDNIGHTBSD01ASH_COMPAT” just in case they decide to
  require it and show it in the ksh version automatically
• sync the use of non-ASCII characters over files (unification)
2009-05-16 18:40:09 +00:00
tg b145ca5c9f • sync distrib/special/mksh/Makefile with bin/mksh/Build.sh and
fix the regression test’s results while here, which have been
  broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
  bian; track down commits in all files of oksh-mirbsd and mksh
  to get correct copyright years per-file, as is BSD custom
2009-05-16 16:59:42 +00:00
tg 1e6f3605b5 sync rcsid with openbsd; we did it in misc.c,v 1.95 already
what they kludged in now

tg 32bc1dc40e sprinkle mksh_ari_t to limit arithmetics to 32 bit even
on Debian Lenny/amd64 (XXX need more verification; this
can be used for 64 bit arithmetics later too)

PPID, PGRP, RANDOM, USER_ID are now unsigned by default

tg a97a514aba gmatchx debug (if 0'd) 2009-02-22 18:53:03 +00:00
tg 1b3e4a3a2e when outputting in a row x column formatted way, but the available space
on the screen is not enough for two columns, just output the text line by
line, instead of trying to format it; gets rid of superfluous empty lines
if we did not even have space for one column on the screen (x_cols)

noticed by Gábor Gergely in irc, thanks!

tg 06626b0de2 ensure sizes of long and unsigned long are the same #ifdef DEBUG 2008-12-17 19:37:08 +00:00
tg 31d1499219 * back out almost all of the memory allocator related changes, as aalloc
was hard to type and hard to fix, galloc is also hard to fix, and some
  things I learned will probably improve things more but make me use the
  original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here
2008-12-13 17:02:18 +00:00
tg 042086e49e rename utf8-hack to utf8-mode (use set -U or set +U instead, anyway)
and announce less hackish things
2008-12-04 18:11:08 +00:00
tg 4d3fc2413e switch to a (nmemb,size) API from a (nmemb*size) API
cost: text += (308, 256, 4, -100)
2008-11-12 00:54:52 +00:00
tg c80c28633b change use of “Area *” to “PArea” and “struct Area” to “TArea”
no change in size (mgcc and pcc, small and full)

tg bf3194e937 save 1640 .text bytes in MKSH_SMALL case by not inlining strdupx, strndupx 2008-10-28 14:51:06 +00:00
tg 88d7b7d08b • rewrite code to no longer use statements-as-expressions
• optimise a little
• Build.sh: remove HAVE_EXPSTMT test
• Build.sh, */Makefile: sort tests, regenerate
• mksh.hts: sync clog

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 68e028ea4b fixes for constant conditionals, from gcc-4.2 fat binary building 2008-07-18 11:33:13 +00:00
tg 04bc7ba51a we're up to 133214 for MKSH_SMALL, as I missed a NULL pointer check
in the MKSH_SMALL case… so the speed, code size, and number of insns
is the same as before for that, except that the NULL pointer check is
moved to possibly save a function call, and that the function call may
be inlined or jumped
2008-07-12 18:24:58 +00:00
tg 03c4a1934a for MKSH_SMALL, reduce code size, even at cost of performance 2008-07-12 17:56:37 +00:00
tg 06b83a8df8 600 bytes more for the small version aren't worth it; it looks
as if there are not many NULL pointers to be optimised away
2008-07-12 17:47:21 +00:00
tg b6236be77a further optimisation attempts in the str_save() and str_nsave() area 2008-07-12 17:23:00 +00:00
tg 9eae0851ef • sync RCSID with oksh, Miod fixed a bug which fell out during my size
optimisation whack earlier in mksh
• optimise a little more for the (s == NULL) case while here
  (more to follow…)
2008-07-12 16:26:58 +00:00
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
2008-05-17 18:47:03 +00:00
tg 7a06275658 shrink code size for a corner case 2008-05-04 02:02:32 +00:00
tg 7b645a40c3 remove the now-unused addition to the ksh_getopt() code
which oksh used for their ulimit change, as I’m not going
to hack on it for now… maybe editing the optstring as it
is parsed (in the first loop), but… naah, not now
2008-04-22 19:00:01 +00:00
tg a3dab099d9 sh.h can provide its rcsid itself, no need for that ugly hack 2008-04-22 18:57:26 +00:00
tg 9b62cf15bf • more unsigned → unsigned int
• more int → bool
• more regression tests: check if the utf8-hack flag is really disabled
  at non-interactive startup, enabled at interactive startup, if the
  current locale is a UTF-8 one
• make the mksh-local multibyte handling functions globally accessible,
  change their names, syntax and semantics a little (XXX more work needed)
• optimise
• utf_wctomb: src → dst, as we’re writing to that char array (pasto?)
• edit.c:x_e_getmbc(): if the second byte of a 2- or 3-byte multibyte
  sequence is invalid utf-8, ungetc it (not possible for the 3rd byte yet)
• edit.c:x_zotc3(): easier (and faster) handling of UTF-8
• implement, document and test for base-1 numbers: they just get the
  ASCII (8-bit) or Unicode (UTF-8) value of the octet(s) after the ‘1#’,
  or do the same as print \x## or \u#### (depending on the utf8-hack flag),
  plus support the PUA assignment of EF80‥EFFF for the MirBSD encoding “hack”
  (print doesn’t, as it has \x## and \u#### to distinguish, but we cannot use
  base-0 numbers which I had planned to use for raw octets first, as they are
  used internally): http://thread.gmane.org/gmane.os.miros.general/7938
• as an application example, add a hexdumper to the regression tests ☺
2008-04-19 22:15:06 +00:00
tg 7ddf56dbbc • new ksh_mbswidth
• fix: when printing menus (tab expansion, for instance), honour width of
  the multibyte characters printed
• some int→bool while here
2008-04-19 17:21:55 +00:00
tg 6c6be2a87e _careful_ (feature) sync with oksh:
(3 weeks, 5 days ago) by millert
Make ulimit able to get and set multiple limits in a single invocation
like bash and zsh do.  Requested by espie@, OK deraadt@
2008-04-16 21:56:03 +00:00
tg fc607a6c1b SECURITY fix: when spawning mksh on a new terminal (tty, not /dev/null),
flush all of its I/O first – someone could have written on it beforehand
2008-04-11 19:55:24 +00:00
tg 37af1f3087 more
• int → bool
• shprintf("foo") → shf_puts("foo", shl_stdout)
• shprintf("%s", foo) → shf_puts(foo, shl_stdout)
• shf_puts("x", foo) → shf_putc('x', foo)
2008-04-01 21:50:58 +00:00
tg e8d61a1d99 • unify ksh_dup2() usage, use bool where appropriate
• 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
2008-04-01 20:40:22 +00:00
tg 83b8798da3 support dæmonisation in mksh, for example
|	csh -cf '/command/svscanboot &'
and
|	/usr/mpkg/bin/pgrphack /usr/mpkg/bin/svscanboot &
can now be replaced with
|	/bin/mksh -T- /usr/mpkg/bin/svscanboot
2008-03-23 22:09:59 +00:00
tg 01b54f1fd5 I _think_ this implements ${foo/bar/baz} logic (bar is a glob pattern)
todo tomorrow:
• test case (compare with e.g. GNU bash)
• manpage
• version bump

sqchar is a bit ugly, but \/ must be preserved, as we don’t get wdencoded
strings later on in the process (eval.c CSUBST) and I didn’t want to have
an implementation like ${foo: 2: 3} this time

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 18804b3555 silence a gcc-4.2 warning and, in doing so, save quite a few operations:
• a NUL termination
• a strlen()
• a pointer comparision
• eventually a function call
replaced by
• a pointer subtraction
