tg 5d6b21fda2 it's FALLTHROUGH, 10x moritz@obsd 2007-06-04 19:25:45 +00:00
tg a84655e3e0 fix Coverity CID #8, #9
it's wrong to use strchr(s, 0) to look for the NUL byte, because in some
environments it apparently might return NULL

use new macro strnul = s+strlen(s) instead (not side-effect safe tho)
2007-05-13 19:14:05 +00:00
tg 96283ed453 Workaround for Coverity CID#1: the Prevent parser didn't recognise there
were multiple possible values for c inside the code.

Rewrite code in question to use if instead of switch; optimise while here.

tg d2d035355f a certain size optimisation broke the utf8bom-3 regression test if
mksh was configured to have utf-8 mode “always on” (because it's
really only always on for interactive shells); setting it to really
always on would break the other half of this regression test, so
do the optimisation only if MKSH_SMALL
2007-05-10 19:22:11 +00:00
tg c0e5c09351 optimisation: #ifdef MKSH_ASSUME_UTF8, don't bother to “Flag(FUTFHACK) = 1;” on UTF-8 BOM encounter, it's always on (unless manually set to off) – saves a few bytes, I guess 2007-04-26 11:58:53 +00:00
tg 680e8ebd3f if we read an utf-8 BOM, enable the utf8-hack flag (we can test for that on
mirbsd even because the main.c enabling is only run for interactive shells)
2007-04-15 12:28:38 +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

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)
  YES, THIS BREAKS -rHEAD, I KNOW.
* while here, fix spelling

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 a373d2e7ab first part of utf-8 ability in mksh, already works pretty well 2006-11-05 15:31:37 +00:00
tg 790c312e9f fix the prompt redrawal routines for multi-line prompts, prompts
with embedded newline (\n), and multi-line prompts with embedded
newlines. single-line prompts should be not affected; prompts with
embedded carriage return (\r) should be fixed by this as well.
also fix prompt_redraw comment (can't remove the variable though,
since it's required if the shell inserts a newline after the prompt
herself).
tested on cygwin and interix

tg df54522223 * Build.sh: fix accidental CR-LF catastrophe
(yeah, that's what you get from developing with a
  16-bit MS-DOS(R) executable of your favourite text editor)
* lex.c, mksh.1: do not print the delimiting character for
  not-to-be-counted character sequences (i.e. ANSI escapes)
  in prompts any more, mostly because ASCII 01h is printable
  on both Interix and Cygwin and I'm lazy
  (this also fixes prompt width counting if a printable character
  such as 'x' is used as delimiting character)
* lex.c: through printing the prompt character by character,
  also print the delimited sequences if skipping, fixes some
  prompt redrawal not honouring colours stuff while not totally
  redrawing the entire prompt
2006-08-02 10:41:03 +00:00
tg 857fb659bc fix multiline prompts with "delimiter chars"
(only the last line of the prompt is redrawn, keep this in mind
when doing the ANSI colour game)

TODO:
* maybe go back up one line and redraw whole prompt?
* optionally edit command on multiple lines, bash-like,
  instead of scrolling horizontally
2006-08-01 14:59:51 +00:00
tg a15c5c319a * use modulo operation, Mr Glockner

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

tg f38d8299f9 Change interpretation of '\"' in here documents with substitution
according to SUSv3 and other modern shells (POSIX allows both).
Idea for the patch (add another lex state) from OpenBSD, but the
implementation differs slightly (and is better in quality).

Also add two testcases (/bin/sh passes both, old mksh only one),
and document the change in the manual page. Sync RCS IDs with OBSD.

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 8a1afa6087 experimental diff:
From: Todd C. Miller <Todd.Miller@courtesan.com>
The following ksh diff needs wide testing.  It does the following:
 1) proper error message for bad substitution.
    Before:
        $ echo ${a[@]:foo}
        ksh: : bad substitution
    After:
        $ echo ${a[@]:foo}
        ksh: ${a[@]:foo}: bad substitution
 2) fix a core dump for "echo ${a[@]:?foo}".
 3) fix a use-after-free bug (from otto@)
