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 7071cada42 • use wdcopy() not str_save() to duplicate an “encoded string”, whatever
• prevent out-of-bounds memory access, cought by glibc malloc on IA-64

tg e0e432347b Minix 3 has no S_ISSOCK (probably not even UNIX® domain sockets)
and lacks other things (rlimit stuff), so it won't make it today
2007-03-04 05:14:10 +00:00
tg 17d0fd1e23 more NSIG 2007-03-04 05:04:54 +00:00
tg 0a20bb8dd4 • Minix 3 doesn't have <sys/mman.h>
• Some OSes might need <stdint.h> for int32_t (Minix 3 with GCC)
2007-03-04 04:36:45 +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 5891915f1b * Scan for __attribute__((...)) in general (the earliest was 2.5,
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
  if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
  scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more
2007-01-12 01:49:29 +00:00
tg 2f15a11c55 Clean up the signal mess, saves 172 Bytes:
* 'sigseen' in Build.sh goes away
* Signal name existence is checked in this order:
  have our own¹ -> sys_signame[] -> _sys_signame[] -> build our own²
* Signal description existence is checked in this order:
  sys_siglist[] -> _sys_siglist[] -> strsignal() -> NULL³
¹ Predefined list of items, for operating systems where we
  cannot build² them, i.e. Plan 9 and Minix 3 (e.g. no $CPP -dD)
² The usual cpp(1) stuff
³ Changed later, see below
* Make $CPP test dependent on $NEED_MKSH_SIGNAME (others can
  be added here, this is not absolute)
* Make signal name list generation² dependent on $NEED_MKSH_SIGNAME
* Fix check if the generation worked
* Guarantee that sigtraps[*].name and sigtraps[*].mess are valid
  C strings; this makes the code shorter *and* removes a few pos-
  sible nil pointer dereferences
* Embed autoconf'd usages of sys_sig* / strsignal / mksh_sigpairs
  into inittraps()
* Check for each signal 0<=i<=NSIG that
  name is not NULL or "" -> replace with ("%d", i)
  mess is not NULL or "" -> replace with ("Signal %d", i)
  name does not start (case-insensitive) with "SIG" -> name += 3
* In gettrap(), fix check if signal name starts, case-sensitive
  or case-insensitive, depending on need, with "SIG" (bug from millert@)

Other changes:
* Build.sh: ac_test[n]() are documented
* Build.sh: ac_test[n]() can have negative prereqs as well now
* Build.sh: use <<-'EOF' consistently
* bump patchlevel to today

tg e960fabf63 expand ~foo to getpwnam("foo")->dir only #if !defined(MKSH_SMALL)
this makes it possible to build a (small) mksh on glibc systems statically

tg b725114422 use RLIMIT_AS, after much RTFM 2007-01-06 18:48:27 +00:00
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 1f6ba50590 this is mksh, benzday edition (2006/12/07)

2006-12-11 16:09:49 +00:00
tg 15a0b1a021 catch up openbsd manpage changes: typos; from alf schlichting,
and revisit the RLIMIT_AS issue
2006-12-06 13:46:28 +00:00
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.
2006-11-19 20:43:14 +00:00
tg c2e79abc08 make mksh compatible to the AT&T ksh spec which says, according to
twkm (from #ksh on freenode), that $RANDOM is always an unsigned
15-bit decimal integer.

(RANDOM << 15 | RANDOM) thusly yields 30 bit, which is still more
than 36^5, so we can use it on the baselife CD to speed things up
2006-11-19 16:43:43 +00:00
tg d3dea44bb5 whitespace fixes 2006-11-16 13:35:00 +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

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

2006-11-10 07:18:58 +00:00
tg 35b30679c7 since so many internal things hardcode 'C' locale anyway,

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
2006-11-10 06:27:09 +00:00
tg 2342fa1242 don't use setreuid(2) etc. stuff, like OpenBSD
only affects suid shell scripts, which are *ugh* anyway,
and I really have no idea what the old code did, when, why, etc.

2006-11-10 03:23:50 +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)

* 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 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).
