tg 5488e79d3b introduce a nosymlink check category (idea by RT); pass it to test.sh; use cp if ln -s fails (me) 2012-05-04 21:42:51 +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 5204e7cc4f after discussion with ciruZ, switch mksh from NZAT to NZAAT fully
to get rid of the bias introduced by making the hash never zero

… he also pointed out a memory (heap) usage optimisation… which
may impact code size a bit though as I’d need to pass an additional
argument on hashtable function calls… or, forgo the benefit of not
having to pointer-align the key in the structure, which can be as
much as 3/7 octets per item, heap storage… OTOH the saved space is
4/8 octets per not-allocated item, possibly some code (use of an
multiply-add opcode), but the function call overhead/cost would
possibly be quite a bit… I guess I’ll have to measure…

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

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 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)

tg 2578c66b61 move linkage check (which uses sh.h INCLUDES_ONLY) to when all of its
prerequisites are actually fulfilled, i.e. evrn further down than with
the last commit doing this, and move some prerequisites of stuff that

assert changes to the outside, too

tg 971b153933 catch intmin/-1 instead of dumping core on SIGFPE; from Jilles Tjoelker 2011-12-11 01:35:10 +00:00
tg 3b87d173d4 • finally, the code and manual page text to deprecate, and code to not
handle any more, octal 010 style constants, as promised
• overhaul the manpage re. arithmetic expressions, make the guarantees
  mksh code has explicitly, precisely, clear
• to reduce burden of the compiler, getint() now operates on mksh_uari_t
  internally; it already applied the sign after operation, anyway (C99
  guarantees wraparound on unsigned types, but for signed types we need
  specific compiler support; apparently, this comes from hardware limits)
• use const and shuffle order of locals around while here

tg 15cfc6c88d add tests for
• integer base flat (10, 010, 0x10)
  ‣ posix, right variants (heh, just like timezones)
  ⇒ both enabled, which means one test always fails right now,
    until the code changes are in…
  ☹ mksh R21 and up, AT&T ksh93, posh, GNU bash, busybox sh, dash
    all use the posux variant
  ☺ mksh R20b and below, pdksh, zsh, python, perl, php all do it right
  ‣ posix is stupid to use C (strongly typed, compiled) semantics
    for an untyped _scripting_ language
• integer bases 1 (mksh specific), 2 to 36, and that 37 errors out
  ‣ both directions
• integer arithmetic, signed and unsigned, wraparound and value span

tg 2fb9df56e4 rewrite funcs.c:c_test(), i.e. test(1) and [(1), to follow POSIX and XSI
in the cases where they are defined unambiguously; bug reported by
Jilles Tjoelker in <20111129232526.GC14357@stack.nl> due to a report
by Stefano Lattarini on bug-autoconf

in the ambiguous case, I stick to traditional pdksh behaviour, which means
	test ! a = b	vs.	test a = b
and
	test ! a -o b	vs.	test a -o b
behave different from each other (in the second case, the NOT operator
binds strong; POSIX demands a reduction to 3 arguments and negating
that result in the first case), so we're at two known not-ok in the
FreeBSD® testsuite. (81 and 82 in regress.sh,v 1.3)
