tg b1aa05e36e do not use $(uname -s || uname) as TARGET_OS if it’s the same as $(uname -n), to weave around many ancient unicēs; idea discussed with RT 2012-05-04 21:37:08 +00:00

tg 2d0ca10629 patch test.sh to support check.t split into multiple chunks
which is apparently needed on Coherent due to OS limits

inspired by a patched test.sh from RT, except I require a
dot before the sequence number for easier globbing, made
the splitting use -S, and the errorlevel is more correct
2012-05-04 21:28:06 +00:00
tg 5780bc5eb7 new MKSH_NO_CMDLINE_EDITING to disable command line editing in its entirety
mainly for the Plan 9 port though it may also help the WinAPI variant,
other porting efforts, as well as a new project I cannot say yet
2012-05-04 20:49:08 +00:00
tg b67de6ba17 add experimental code to use sigprocmask+pause+sigprocmask ipv sigsuspend (and harden j_sigchld handler for that) to improve working on BeOS 5.0 and Coherent UNIX, found by RT 2012-04-27 16:16:23 +00:00

tg 29e4269f33 if the OS does not provide sig_atomic_t and/or ssize_t, you can now define
MKSH_TYPEDEF_SIG_ATOMIC_T and MKSH_TYPEDEF_SSIZE_T via CPPFLAGS to the
*correct* definitions (it’s absolutely critical they be correct!)
2012-04-14 14:02:40 +00:00

tg 0af5e1f288 can’t forget LynxOS, although it’s still preliminary… 2012-04-06 23:10:50 +00:00
tg 3d3081115b if LDSTATIC is not empty (i.e. "-static" or " "), always add “our” sources:
• strlcpy
• utf_wcwidth
note strchr/strstr from misc.c are still #ifdef DEBUG only, as they are
not eligible: they’re for const-cleanliness debugging purposes

XXX get rid of multiple occurrences of binary search code, too…
2012-04-06 15:20:42 +00:00

XXX recheck this with all the others, e.g. NeXTstep

tg 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
tg 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
2012-04-01 04:57:24 +00:00
tg 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

tg 307224f143 Use “proper C code” for determining the compiler type even though we use
only cpp for this: NeXTstep things otherwise:

tg 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
tg 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
2012-03-29 19:23:01 +00:00
tg 25745883a9 move USL C detection to after GCC detection, apparently the latter
masquerades as the former on SCO systems

tg 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,

tg 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
2012-03-27 22:36:53 +00:00
tg e3b9f14d88 You have this ↓ guy a lot to thank for.

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)

  from calloc() to a checked malloc() for simplification while there
