tg 499327f7b8 add “set -o arc4random”, RTFM for details 2007-08-12 13:42:23 +00:00
tg 979406bba7 • support IBM xlC on AIX
• fix all bugs it could find ☺
2007-07-22 13:34:52 +00:00
tg 56a8da33cf • make the "if called as sh, set FPOSIX" not !SMALL-only
• bump to R30-gamma, feature freeze
2007-07-17 13:56:51 +00:00
tg 2e42fa62b6 Borland C++ found these 2007-07-01 21:10:29 +00:00
tg 36188c60be coerce this into running on UWIN - or rather sort of. Ugly. 2007-07-01 19:04:53 +00:00
tg e596de4759 make sure that “integer” and “local” are defined even in FPOSIX mode, which
is a compromise anyway; these lunox people will have to live with that, too
many existing korn shell alike scripts depend on it even if not on the full
korn shell syntax availability (note: this doesn't mean using these in some
script with #!/bin/sh is ok)
2007-06-17 00:50:09 +00:00
tg 199994fed8 we can do all that 2007-06-16 15:02:56 +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 1b16db54f1 implement that if we run in FPOSIX mode we don't set up the standard
Korn aliases
2007-06-15 20:52:19 +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
2007-06-06 23:28:17 +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 1692a6da66 ignore the UTF-8 Byte Order Mark at the beginning of the input (via a file
given to execute, standard input (interactive or not), via -c command line
argument, or after “eval”, but not for $(…) comsubs, at the beginning of a
subsequent line, or within a line, etc.); regression test for it

idea during my “week off” (despite the pain), bsiegert@ thinks it's good –
and utf-8 capable tools ought to be able to do this anyway
2007-04-15 10:45:59 +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 dbf5cdf632 * main.c: prevent segmentation faults on inferiour operating systems
such as Debian GNU/Linux "etch" 4.0 with not installed locale file
  corresponding to the current environmental settings. ばかたち!
2007-01-06 17:08:14 +00:00
tg 17a3fffc26 * main.c: when doing the conversion from strcasecmp (wrongly used)
to strcasestr, it was used in a wrong way (reverse logic error in
  checking its return value), turning to mis-detection of UTF-8 locale.
* sh.h, check.t: bump version

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 62d9cf9fa9 only auto-enable set -o utf8-hack (set -U) for interactive shells 2006-11-12 10:44:42 +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

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

tg c4ef5b801a New feature: read ~/.mkshrc during startup, after the profiles
have been read, for non-priviledgued shells only. If $ENV is
set, ~/.mkshrc is ignored (even if the file pointed to by $ENV
does not exist in the first place).
Feature requested by Jari Aalto for portable mksh because some
operating systems' vendors do not allow touching the profile.

Initial diff and manual page addition by Jari Aalto <jari.aalto@cante.net>
Code changes and manual page correctness by me.

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).
