tg 95a2c63096 • implement fcntl(2)-based advisory locking as an alternative iff flock(2)
is not found, from a suggestion by RT (LP: #912691)
• try harder (in a loop) to acquire a file lock if the locking mechanism
  documents EINTR is a possibility (fcntl always, flock on Linux not .Ox)
• use -std=c99 not -std=gnu99 if it must be at all

tg 7ec1ae3771 followup for cid 1004EE408E1382C1752 and 1004EE40DDD498FBB0D:
do a mirtoconf run-time check (ugh) to see whether the CPU designers
smoked/were brain-dead or if we don’t actually need the manual check
2011-12-31 02:04:18 +00:00
tg a0dd6b5366 disable deprecated code on MirBSD-current mksh-current (note: next to deprecate is support for parsing $((010)) as octal, which is agreed gecko2@ tonight at the Jugo already) 2011-12-08 22:19:16 +00:00
tg 0695039dc0 fix stateptr-underflow; really do call fastbox regression checks; bump vsn 2011-11-26 00:45:21 +00:00
tg 2ff9255f39 add a -f option to test.sh that runs tests of class fastbox
plus a test in that category for a bug spotted during development of

tg e39dea490f sync… various things 2011-04-09 18:47:14 +00:00
tg a796512040 • more comment and int→bool cleanup, add and improve some comments
• in interactive mode, always look up {LC_{ALL,CTYPE},LANG} environment
  variables if setlocale/nl_langinfo(CODESET) doesn’t suffice
• add the ability to call any builtin (some don't make sense or wouldn't
  work) directly by analysing argv[0]
• for direct builtin calls, the {LC_{ALL,CTYPE},LANG} environment
  variables determine utf8-mode, even if MKSH_ASSUME_UTF8 was set
• when called as builtin, echo behaves POSIXish
• add domainname as alias for true on MirBSD only, to be able to link it
• sync mksh Makefiles with Build.sh output
• adjust manpage wrt release plans
• link some things to mksh now that we have callable builtins:
  bin/echo bin/kill bin/pwd bin/sleep (exact matches)
  bin/test bin/[ (were scripts before)
  bin/domainname=usr/bin/true usr/bin/false (move to /bin/ now)
• drop linked utilities and, except for echo and kill, their manpages
• adjust instbin and link a few more there as well

tg 29de79c7bf mknod’s now demoted and only used as special-case builtin, in MirBSD only
built for the installer, to save time, as the original OpenBSD hack wanted

tg 667d792d6a • Address concerns of Chris Palmer from the Android security team
– possible integer overflows in memory allocation, mostly
    ‣ multiplication: all are checked now
    ‣ addition: reviewed them, most were “proven” or guessed to be
      “almost” impossible to run over (e.g. when we have a string
      whose length is taken it is assumed that the length will be
      more than only a few bytes below SIZE_MAX, since code and
      stack have to fit); some are checked now (e.g. when one of
      the summands is an off_t); most of the unchecked ones are
      annotated now
    ⇒ cost (MirBSD/i386 static): +76 .text
    ⇒ cost (Debian sid/i386): +779 .text  -4 .data
  – on Linux targets, setuid() setresuid() setresgid() can fail
    with EAGAIN; check for that and, if so, warn once and retry
    infinitely (other targets to be added later once we know that
    they are “insane”)
    ⇒ cost (Debian sid/i386): +192 .text (includes .rodata)
• setmode.c: Do overflow checking for realloc() too; switch back
  from calloc() to a checked malloc() for simplification while there
• define -DIN_MKSH and let setmode.c look a tad nicer while here

tg a0d43a99fd it’s ugly to write a ./stdint.h file if we can instead define the
types from sh.h; sync clog

tg cb2fd22c38 "official" but unsupported printf-as-builtin code, cleaner API than
in the branch; USE_PRINTF_BUILTIN=1 to enable it (Build.sh + Makefile)
2009-07-30 19:11:12 +00:00
tg 571546c562 • Check if killpg(3) is available; if not, use kill(2) with negative
process ID and hope it works (is POSIXly killpg-endowed)
• bump version
• sync clog
2009-06-08 20:34:40 +00:00
tg b145ca5c9f • sync distrib/special/mksh/Makefile with bin/mksh/Build.sh and
fix the regression test’s results while here, which have been
  broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
  bian; track down commits in all files of oksh-mirbsd and mksh
  to get correct copyright years per-file, as is BSD custom

tg 56c6e384e6 (experimental) implement getrusage via times if not found 2009-04-03 09:39:07 +00:00
tg ca539f08f0 remove espie's double-linked-list based allocator and write a
similarily simple one from scratch, which however performs
better than espie's with AFREE_DEBUG enabled which took away
the benefit of the double-linked-list approach

all of (core) mksh is now MirOS licenced
2009-03-22 16:55:38 +00:00
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
2008-12-13 17:02:18 +00:00
tg d97691ca61 by the principle of the working tree, we cannot enable aalloc as of now.
damn, pointers in C are so uselessly complicated… in asm it’s much easier
2008-11-17 01:14:57 +00:00
tg 90e8e7ea72 rewrite the cookie logic… while this is better than previously,
we still have issues:

(gdb) r
Starting program: /usr/obj/bin/mksh/mksh -c print\ \$KSH_VERSION
mksh in free(): error: modified (chunk-) pointer

Program received signal SIGABRT, Aborted.

tg 255c77ff32 use -DAALLOC_TRACK in MirOS-current but not releases, similar to
-DMKSH_AFREE_DEBUG, which is even similar in functionality

cost 412 code, 32 bss
2008-11-12 07:38:42 +00:00
tg d099b00b53 leave at least a working tree, with zero-penalty -DAALLOC_NO_COOKIES
XXX cookies are still broken?

tg 94b7792718 use mksh realpath builtin instead of readlink -f for canonicalisation
note: there’s still a readlink(1) call left in, for instance, mirmake;
this does not hurt because we initially assumed that readlink(1) does
exist anyway and bundled ours just because some do not have the ‘-f’
option for realpath(2)isation

tg 5d73013c02 remove check_category “pdksh”, it starts to make trouble and was never
taken seriously anyway, just historic ballast
2008-06-21 19:20:15 +00:00

tg def9c172df • Add support for Ultrix 4.5 and ucode cc (?)
‣ I/O redirection seems broken:
    $ (date; date >/dev/null; date) | wc -l
    1 (expected: 2)
  ‣ other than that: working fine
  ‣ -YBSD (default) and -YSYSTEM_FIVE don’t work, just -YPOSIX, somehow
• Fix $(…) to `…` for OSF/1 V2.0 /bin/sh
  ‣ this compiler is FUBAR though:
	$ cat >t.c
	main() { return (foo()); }
	$ cc t.c
	ld:
	Unresolved :
	foo
	$ echo $?
	0
	$ ls -l a.out
	-rwxr-xr-x   1 mirbsd   users      10835 Jul 21 17:12 a.out
  ‣ it seems to have ucode, but man is not installed
• new mirtoconf check: mkstemp(3)
• if !HAVE_MKSTEMP (Ultrix), use tempnam(3)
• only use printf(1) if it exists (it doesn’t on Ultrix)
• a few more signals
• add S_ISLNK if the OS doesn’t define it
• add strcasecmp(3) proto for Ultrix (it _is_ in <portability.h>, but
  only for -YBSD I think)
• fgrep(1) on Ultrix doesn’t do “-e ① -e ②”
