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

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
• some KNF
• bump version

2007-07-22 13:34:52 +00:00
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
2007-07-01 22:17:29 +00:00
tg 572119b454 some <getopt.h> from vendors define a “struct option”, so use a
different name for ours
2007-07-01 16:49:18 +00:00
tg 17b7a28ac8 • check.t: add some FPOSIX regression tests (1 still fails)
• all: remove vi editing mode #if defined(MKSH_SMALL) || defined(MKSH_NOVI)
  saves 12608 byts on i386
• check.t: add $0 quoting
2007-06-15 21:55:20 +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 5dfde5c670 first part of the Intel C Compiler (Linux) shaddap
| tglaser@hephaistos:~ $ /usr/local/intel/cc/9.1.042/bin/icc -V
| Intel(R) C Compiler for 32-bit applications, Version 9.1    Build 20060706Z Package ID: l_cc_c_9.1.042
this one is muuuuch too verbose IMHO, _and_ it #defines __GNUC__ (eek)

2007-06-05 19:48:47 +00:00
tg e392983af7 Possible fix for Coverity CID#7:
convert options() prototype to unsigned (size_t, in fact), and make an
explicitly casted (size_t)-1 the error return code, modelled after what
is often used in Unix libraries
2007-05-13 18:33:29 +00:00
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))
2007-05-13 17:51:24 +00:00
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 98e9111bbc remove the "set -o sh" option (dummy anyway),
"set +o emacs-usemeta" and "set -o vi-show8" which are always on now,
since we have proper internationalisation (i.e. utf-8) support, and
assume the user either has a 'C' locale and can't enter 8-bit chars,
his terminal is 8bit-transparent, or he has a 'UTF-8' locale.
