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?

cost for aalloc.c: data -= (4, 0, 4, 0); text += (1665, ?, 2115, 2217)

tg d15671f6f6 fix first batch of compile warnings, enable aalloc for mirbsd 2008-11-12 04:59:42 +00:00
tg 17ecb986c8 regenerate CPPFLAGS 2008-11-02 22:42:37 +00:00
tg 88d7b7d08b • rewrite code to no longer use statements-as-expressions
• optimise a little
• Build.sh: remove HAVE_EXPSTMT test
• Build.sh, */Makefile: sort tests, regenerate
• mksh.hts: sync clog
2008-10-28 14:32:43 +00:00
tg 5167e7398b sync MirBSD-specific mksh Makefiles after recent Build.sh changes 2008-10-26 22:03:05 +00:00
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
2008-10-05 16:26:13 +00:00
tg a30066cd6f run millert’s afree checker by default (idea from openbsd) if MirOS-current
and not MirOS-stable (via DEBUGLIBS from <bsd.own.mk>)
2008-08-02 17:40:37 +00:00
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 b41a72ac2e add new builtin “realpath” calling realpath(3) on its argument, skipping
over “--” for compatibility to Debian realpath(1) and possibly busybox’

“sounds handy” replaced@TNF

tg aacc0b2179 • Build.sh: be a little more explicit about the unknown compilers
• Build.sh: add another one
• */Makefile: sync CPPFLAGS
2008-03-27 22:44:17 +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”

10x DEChengst:#UnixNL for giving access
2008-03-25 21:34:45 +00:00
tg 845f6f0d64 • check for flock decl too (weird on OSF/1: if !POSIX and BSD)
• un-experimental Tru64
2008-03-05 18:49:15 +00:00
tg 3d9bd0e1f0 OSF/1 doesn’t seem to declare revoke(2) anywhere 2008-03-05 17:06:50 +00:00
tg 8d170a3d01 fix on Interix, where tr(1) is more weird than even Solaris’ XPG4 one…
just do not use ranges, no matter what.
2008-02-29 16:38:41 +00:00
tg d17e25c7f4 fix passing of env var to regression tests 2008-02-29 11:57:30 +00:00

tg 87eeeb6da0 revert the -std=gnu99–by–default change until programmes are ready, as this
is too much annoying (for now) – extra commit so that we have a changeset
2007-08-24 14:25:33 +00:00
tg c8ac9422f9 • add -std=gnu99 to default CFLAGS
• first round of assorted fixes
2007-08-24 14:19:56 +00:00
tg 499327f7b8 add “set -o arc4random”, RTFM for details 2007-08-12 13:42:23 +00:00
tg 496b8f4dc3 • new way of checking for mknod & friends, due to tcc vs glibc weirdness
• bump vsn for the code restructuring
2007-07-31 11:11:25 +00:00
tg f948c13a78 • fix display problem
• add <libutil.h> if it exists – revoke(2) on UWIN
• add <stdlib.h> for NULL in test of mmap(2)
• regen CPPFLAGS for MirBSD native builds
2007-07-01 21:47:08 +00:00
tg 91431e4cf6 with this, we don't need the special list of pre-known signal names
any more either, and can make use of code sharing between detection
of sys_siglist and sys_signame (and the underscored variants); nuke
the now-useless signames.c file too (merge struct into histrap.c)
2007-06-05 21:47:49 +00:00
tg 63c31c43e3 fix for the SUNpro 8 on yofuh's E420:
cc: Sun C 5.8 Patch 121015-04 2007/01/10
2007-06-05 19:48:47 +00:00
tg dee38c5be7 sync 2007-06-04 21:55:38 +00:00
tg 6e1bfd6e4b When compiling native MirOS BSD binaries with SUNpro 12 (don't look like a
car only slower, yes this is possible, and the resulting binary passes the
testsuite just fine), the definition of __RCSID() in <sys/cdefs.h> expands
to something with __attribute__((used)), which triggers a warning, because
__attribute__ in general is supported but the used attribute isn't. Thusly
always use our own strings and get rid of the MULTI_RCSID test (introduced
because __RCSID() on Darwin is inferiour).

Maybe we should fix <sys/cdefs.h> too? #ifdef __SUNPRO_C helps here.
2007-06-04 21:27:53 +00:00
tg 63623bb479 we don't have -d in mksh R30β any more 2007-05-24 09:06:31 +00:00
tg 1a0b51b697 • arc4random, arc4random_push: use our own protos to check
XXX u_int32_t is not ISO C99, but seems to work well enough
  XXX if it fails anywhere, we'll see in the build logs
  XXX apple doesn't have the standard uint32_t and API doesn't specify it
• sys_siglist_defn: rename to sys_siglist_decl as we're really checking
  for the declaration in the headers; change wording to “check if … does
  not need to be declared” since we don't need to declare if we don't use
• scan for arc4random, arc4random_push, confstr declarations too
• sh.h: confstr declaration is no longer #ifdef __sun__; sort
2007-04-24 10:42:02 +00:00
tg 615a7794a6 AIX has sys_siglist[] but doesn't define it anywhere, so add a means to
scan for defns and use it here; bug reported by Kurt Telep
2007-04-23 20:37:16 +00:00
tg c79cacdfa5 • from a MirOS point of view:
place most stuff from /etc/profile in /etc/skel/.mkshrc; admins must make
  sure to copy this file to users' homes on upgrade (benefit: non-login but
  interactive shells also get all the goodies); fix some quoting; simplify,
  reformat, change comments
• from an mksh point of view:
  slight internal changes in dot.mkshrc; external commands are now prefixed
  with “ulimit -c 0”; $TERM is defined; improvement in determining the host
  name (e.g. on Debian if a FQDN is not given); declare locals as such both
  in $PS1 and outside; remove superfluous quoting, quote properly; simplify
  hd alias, add rot13 alias; place RCS ID at the bottom

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

• sync BSD makefiles with Build.sh output
2007-02-18 16:24:13 +00:00
