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.

tg 8adc4a2c56 support systems without setresugid 2006-11-16 13:35:07 +00:00
tg 151d913115 remove all but these __CRAZY=Yes build warnings:
main.c: In function 'main':
 main.c:208: warning: cast discards qualifiers from pointer target type
 main.c:329: warning: cast discards qualifiers from pointer target type

no warnings at autoconf time left either; will take care of these two later
(might revisit changes from this commit), maybe change declararion for the
builtins to have their argv[] be const strings, and go through strict type
and qualifier checking again. this'll further improve stability.

XXX these changes might have introduced (more?) memory leaks,
XXX someone who knows about these tools should verify with
XXX automatic memory usage analysers (valgrind?)

still passes testsuite

tg f7ef916ed9 * fix CR-LF accident
* fix gcc4 warnings in autoconf tests
* Debian needs <grp.h> for setgroups, which seems fairly POSIX

Testsuite succeeds on Debian testing/unstable (i386)

tg a799f50fea scan for setresuid/setresgid and setgroups
no alternative implementation yet
2006-11-12 12:56:10 +00:00
tg 742b9c6725 not being able to get current working directory shan't yield SIGSEGV, oops 2006-11-10 19:11:57 +00:00
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
2006-11-10 07:52:04 +00:00
tg feb7dddd44 * use only macros for ctype stuff any more
XXX one of these uses a gcc extension, ok for now tho
* don't include <ctype.h> any more at all
* don't try nl_langinfo in small mode, just check locale

saves 171 .text, 4 .data, 256 .bss, 1 import
2006-11-10 07:18:58 +00:00
tg 35b30679c7 since so many internal things hardcode 'C' locale anyway,
use own is{digit,lower,upper} macros that go via byte ranges

doesn't affect utf-8 hack because these only operate on single bytes anyway
saves 224t
2006-11-10 06:53:27 +00:00
tg a199d23dfa use setresuid(2) and friends instead, saves 88t 4d 1i
XXX revisit this if we encounter systems without at least
XXX one of setresuid, setresgid, setgroups - only tested on BSD

848 text 12 data 3 imports
2006-11-10 04:07:59 +00:00
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

saves 4 .text bytes and my nerves
2006-11-10 03:45:57 +00:00
tg f8e7fdbb71 use qsort(3) instead of rolling our own
saves 284 in .text, no added import since we already use qsort(3) once
2006-11-10 03:23:50 +00:00
tg f103c6b2a0 use errorf not bi_errorf if we want to abort
saves 16 .text ;)
2006-11-10 02:10:45 +00:00
tg 658dc2b407 rewrite getn() which is some kind of atoi with return code
costs 1 .text, saves 4 .data, 1 libc import
2006-11-10 02:05:06 +00:00
tg 242d2c086d overhaul parse_args - don't use strlcpy and strlen when overkill
also fixes off-by-one

saves 48 .text
2006-11-10 01:52:23 +00:00
tg c60dbdc6cb * change EXECSHELL to /bin/sh (we can override it via environment anyway,
and this is a sensible choice instead of ourselves)
* move this stuff from sh.h into exec.c where it belongs
* simplify set -o stuff

saves 8 bytes
2006-11-10 01:44:40 +00:00

tg 273ca89019 * check.t: add new regression test "typeset-padding-1" according to TFM
* edit.c: remove debug stuff again; next time better use shl.c functions ;)
* sh.h: add format attributes to a few shf functions
* histrap.c, var.c: fix format string mistakes
* main.c, sh.h: error_prefix and warningf take bool not int
* misc.c: make chvt() stuff use shf_* functions
* misc.c: rewrite the TIOCSTTY stuff to be better integrated in mksh,
  since it originally was an external patch
* misc.c: chvt() no longer fails if e.g. chown fails due to e.g. R/O / fs
* var.c: fix typeset padding for right-justified zero-filled

tg 1547b04e66 add new "set -o utf8-hack", currently no effect
set automatically on startup if we have locale functions (on MirOS)

tg c81966621a merge non-Plan9-specific stuff from the branch, add KNF, etc. 2006-08-24 20:32:53 +00:00
tg 4fac7ec24b * remove redundancy
* integrate compat.h, version.h into sh.h (dependency trick didn't work anyway)
* mention #ksh in mksh(1) since the founder (twkm) said it's on topic too
  (don't remove mention of #mksh despite it's usually empty because of control)
2006-08-22 22:49:38 +00:00
tg a87ff74cbd * version.h doesn't need an RCS ID
* compat.h does, add it to misc.c, always include it, move if NEED_COMPAT
* major whitespace cleanup in sh.h
2006-08-22 22:16:04 +00:00
tg 1100be9300 re-implement "set -o posix" which doesn't do much ;)
but turns off 'braceexpand' when turned on as side effect,
just like oksh/pdksh.
document "set -o sh" too.

tg 5e619e1ef3 style(9) 2006-08-01 13:43:28 +00:00
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
2006-05-10 18:54:13 +00:00
tg 8226efa566 use \t not \n for separating RCS IDs
ident(1) finds both similarily, and as doesn't bitch
2005-11-24 19:39:10 +00:00
tg 95cfad6339 * only have one $MirOS RCS ID per file to shrink source size
(this is an exception from normal use)
* bump to R26
2005-11-22 18:40:44 +00:00
tg 9b97d72d5e * move _all_ #include stuff into sh.h
* sort out #include stuff which isn't necessary on MirOS into compat.h
2005-10-25 19:53:29 +00:00
tg ee7992988b * move <sys/param.h> include to sh.h
* fix compilation and invocation of test suite with whitespace in
  the pathnames for real, this time
* clean up (especially whitespace)

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).

tg d8d708aa45 * un-hook bin/ksh, usr.bin/xmlwf and lib/libexpat from the build
- expat as discussed with bsiegert@ today on the phone
  - ksh as announced earlier on the lists
* un-hook lib/libexpat from make includes
* remove /usr/include/{,open}ssl upgrade workaround from includes/Makefile
* nuke old bin/ksh
* nuke libexpat and xmlwf
