3b2d9322ec change signal probing order: prefer e.g. SEGV over BUS when same Nr. (BeOS) 2012-04-01 17:17:45 +00:00
tg
c30bf73a56 BeOS has no tty nor uid/gid other than 0, a̲n̲d̲ a broken /bin/sh 2012-04-01 16:55:16 +00:00

412a96d29a speed up Generating list of signal names (XXX can we wrap this into one compile, anyway?) 2012-04-01 16:40:26 +00:00
tg
607a2af260 found the actual reason… cc -E does syntax check and wrap with whitespace ☹ 
also we can only do NeXTstep 3.3 with -posix, but not 3rdpty egcs or OS 4.2

a3fd4f62e6 • move behavioural changes topmost (locale, zsh emulate sh, solaris xpg) 
• attempt to handle cpp on nextstep by using -save-temps
• work around another nextstep bug that may or may not hit us, found by RT:
  ‣ http://lists.gnu.org/archive/html/autoconf/2003-11/msg00094.html
• hide "dirname: command not found", scary even if it might help debugging

2a833165a0 add xep bounds check in x_goto, maybe this will fix the problem the Motorola guys are havink 2012-03-31 19:52:34 +00:00

3c4d2602ac use Errno, not POSIX, to get EINTR; maybe this is more portable 2012-03-31 18:47:20 +00:00

9646c98356 I give up on writing (1 << 31) in any form. 
Now we just use 0x80000000UL and cast that to mksh_uari_t and,
if required, that to mksh_ari_t afterwards.

ac18ec3752 one more case of cpp(1) wanting C syntax on NeXTstep 2012-03-31 17:42:58 +00:00
tg
307224f143 Use “proper C code” for determining the compiler type even though we use 
only cpp for this: NeXTstep things otherwise:
] conftest.c:42: illegal external declaration, missing ;' after `gcc'
| NeXT Computer, Inc. version cc-437.2.6, gcc version 2.5.8
| NeXT DevKit-based CPP 3.1
| GNU Objective-C version 2.5.8 (80386, BSD syntax) compiled by GNU C version 2.5.8.

e67b98e21b use _setjmp/_longjmp on NeXTstep: its Intel port always restores the signal mask on siglongjmp, which we never have 2012-03-31 17:30:00 +00:00

86c4ea4619 add (#ifdef DEBUG) an assertion that xcp <= xep before doing an Emacs mode

4e8c5c078d RT suggests to drop sys_siglist and _sys_siglist on *all* SCO products, for now, and whitelist those that do need it (no strsignal) 2012-03-30 10:24:45 +00:00
tg
9cac4c92f6 RT wants to make the awk used configurable, apparently OpenStep 4.2 has a broken default one 2012-03-30 09:27:19 +00:00

cf75e7b6ce couple of minor/cosmetic fixes from RT’s compile farm: 
• promote SCO OpenServer and UnixWare to !oswarn
• omit trying -O2/-O on OpenServer 5 and USL C
• cast mksh_ari_t to int, mksh_uari_t to unsigned int for printf
• skip ulimit-1 on syllable (which is still too broken)
• write ((mksh_ari_t)-2147483648) ipv UB ((mksh_ari_t)1 << 31)
  and add a comment that that is actually meant
• rewrite functions returning !void ending in NOTREACHED
  so they’ve got a jump target returning an error at the
  end, to aid older compilers and just to be safe
• cast struct stat.st_size to off_t or size_t explicitly when needed
• shorten struct env by two bytes and an alignment, at least

also, optimise control flow and fix more paren matching cases

25745883a9 move USL C detection to after GCC detection, apparently the latter 
masquerades as the former on SCO systems

df8881b9c8 fix embarrassing typo (and I thought I had tested them all), 10x RT 2012-03-28 11:14:20 +00:00
tg
914c1d816f drop call to "custom", SCO says to use it to identify system, 
but RT says it opens a GUI window, and we obviously cannot have this

16ac73b074 g/c magic definitions for simple chars (as opposed to e.g. tokens/lexems) 
some (such as NOT) were already gone; this should unconfuse; most were
unused anyway…

340cd95cf0 #undef flock (LP: #912691) 2012-03-27 22:41:17 +00:00
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

1f96d87aea • MFC almost everything not breaking backwards compatibility or introducing 
deep changes into R40-stable branch
• Version accordingly: HEAD gets 2012/03/24 (hi Eddy/Chris) so we backdate
  $KSH_VERSION for R40-stable to 2012/03/20 (hi David) as that comes before
  even though it includes today’s latest fixes
• Also, sync clog (including MFC indicators)

e83e43aaa5 block things like SIGWINCH¹ during builtin sleep, they get rescheduled 
on unblock just fine and hurt since they interrupt select(2)

① and² SIGPIPE, SIGINFO, SIGUSR{1,2} in addition to already blocked SIGCHLD
② exact list open for suggestions – I’ve got no idea what I’m doing…

21c15c0b8f huh, I thought I had extended ${parameter@#hash} already; make it so now, 
but not yet things like ${parameter@Fi} (1 if integer, 0 otherwise), etc.
also bump patchlevel and © years in recently changed files
