tg 14dc6071e7 portable hogwash 2010-08-14 19:55:37 +00:00
tg c187f3089f a tad annoying, when external programmes such as GNU screen are running,
we don’t get SIGWINCH when the window size changes during the runtime of
that, so, the signal is only usable reliably during editing in the shell
and we re-check the window size before each interactive edit line again

tg c11d35312a Michal Hlavinka from Red Hat found another SIGSEGV
fix: when iterating over all Sources, know when to stop…

tg c6eedad976 *sigh* this code is interesting: assume you want to output via shf to
a string buffer whose window size is currently 32 (initial), your data
is 96 bytes, this routine used to resize the buffer to 64, append your
first 64 bytes to it (no matter if there's already something in it)
and then writes the remaining bytes to stdio fd instead of the string…
if it doesn’t SIGABRT before

discovered by wbx@ – thanks – bug inherited from pdksh 5.2.14 (AD 1999)

tg f10186fedd new MKSH_A4PB cppflag: force use of arc4random_pushb(3) during seeding
just the way sysctl KERN_ARND currently is used on OpenBSD/MirBSD (for
manual packager overrides only, no mirtoconf check; e.g. for Cygwin)

tg 7c91e018f4 • merge printf from OpenBSD
• deactivate %a and %A since our libc doesn’t have it
• rewrite the mksh integration code to use shf instead of stdio, removing
  floating point support always in the process, as shf doesn’t support it
  ⇒ saves 11114 (6706 text, 168 data, 4240 bss) with dietlibc on Debian
• fix -Wall -Wextra -Wformat -Wstrict-aliasing=2 for gcc (Debian 4.4.4-7)
• fix these and -Wc++-compat for gcc version 4.6.0 20100711 (experimental)
  [trunk revision 162057] (Debian 20100711-1) except:
  – a few enum warnings that relate to eglibc’s {g,s}etrlimit() functions
    taking an enum instead of an int because they’re too stupid to adhere
    to POSIX interfaces they design by themselves
  – all “request for implicit conversion” involving a "void *" on one side
• tweak the manual page somewhat more

Revision 1.136: [7]download - view: [8]text, [9]markup, [10]annotated - [11]select for diffs
   Thu Jul 15 20:04:35 2010 UTC (47 hours, 56 minutes ago) by schwarze
   Branches: [12]MAIN

   Changes since revision 1.135: +7 -7 lines
When the first argument or arguments of a macro are opening delimiters
(parentheses and/or square brackets), both modern groff and mandoc first
output those leading delimiters as plain text, then start the macro scope
after these opening delimiters.  This is similar to printing trailing
punctuation and trailing closing delimiters on a macro line outside and
after the macro scope.  For example, ".Sq ( text )" is "(`text')",
not "`(text)'".  Thus, we now need to quote leading opening delimiters
when we want them inside the macro scope.
These are the cases in src/bin.

tg 6b006202a1 partial oksh sync (RCSID and do add some parenthesēs to the list of
reserved words, but really only these which are only recognised at
the beginning of a line as the context says, not blindly all of them)

tg ad98b9fc4a compatibility: stick “set ±o arc4random” around for a bit longer,
until R40 is definitively out (so there MAY still be an R39d)

this commit can easily be reverted in its entirety later, when
Build.sh’s compatibility for “-combine” &c. is removed too

tg 0a5d6bc71b use string width, not length, if we have it 2010-07-11 13:54:37 +00:00
tg a6c81ea978 on obsd/mbsd, entropy is cheap enough for us to do this (codepath in
kernel checked for both) for additional seeding ($RANDOM is still from
the LCG only)

tg 2d6b4acba1 simplify a bunch of things (no SIGWINCH handler, errno is saved for
an shtrap automatically) and gratitutous reformatting of comments

tg 747b27a846 apply diff from manuel giraud via oksh to keep track of LINENO in a trap 2010-05-22 12:49:16 +00:00
tg 2a72f0e2f0 RCSID sync with oksh, and apply a simplification of theirs, but WITH a
comment what/why added (to aid understanding this code)

I wonder, though, why their x_escape now almost¹ looks like ours… is
that a coïncidence, or do they steal again (without understanding why)?

① they’re missing the semicolon but falsely added the closing bracket

tg faaa517636 • deprecate¹ -longoptions in favour of short options
‣ -combine → -c combine
  ‣ -llvm → -c llvm -O
  ‣ -llvm=x → -c llvm -o x
  ‣ -valgrind → -g²
• new option -v (version)
• new options -c (compile mode³), -o (opt flags), -O (reset opt flags)
• opt flags default to -std-compile-opts (llvm) now
• support⁴ the LLVM dragonegg plugin for GCC
• sync list of removed files (*.bc, *.ll, add missing Rebuild.sh)

① old options still valid but emit a warning
② except this one
③ compile modes are:
  • normal
  • makefile (-M)
  • combine (old -combine, new -c combine)
  • dragonegg (new -c dragonegg)
  • llvm (old -llvm, old -llvm=*, new -c llvm)
  the first two are not settable via -c though…
④ sample use:
  tg@seduxbox:~/x$ export PATH=$PATH:/opt/llvm/bin
  tg@seduxbox:~/x$ CC='/opt/gcc-4.5.1/bin/gcc-4.5.1 -fplugin=/opt/llvm/lib/dragonegg.so' sh ../mksh/Build.sh -c dragonegg -r

tg 01a0d1104a address two performance issues in do_realpath():
