tg 4778a2a62f lesson learned from http://k1024.org/~iusty/blog/entry/perf-null/ – add -DMKSH_SMALL_BUT_FAST which gives more speed (8/20K less cycles, 5/9K less insns, 1.8/2.4k less branches, 65/275 less branch misses) on Debian/amd64 (klibc-static/eglibc) at cost of 0/2 more page faults and 6K/6K more text size 2012-07-01 15:55:00 +00:00
tg c1f821d4e5 (mksh) tighten 32-bit requirements; (lksh) switch to long; allow any bitness 2012-06-28 20:17:39 +00:00
tg ae26f45417 fix emacs/vi lksh 2012-06-28 20:14:17 +00:00
tg ea01d80833 hackish work-around the lexer to make alias definitions in mksh -c
work (Closes: #517009) and mention in the manpage why they sometimes
do not work (doing so for COMSUBs is not worth the effort)

tg d824683000 ensure that case end tokens are not mixed up (Closes: #220272)
XXX token/tpeek/musthave should rescan the last input lexems
XXX if the new cf passed doesn't match the last cf passed

tg 5386859b3f also get back octal crap for LEGACY KSH 2012-06-25 16:31:18 +00:00

tg 967e929e98 add basic LEGACY KSH mode (Build.sh -L), no changes yet 2012-06-25 16:05:10 +00:00
tg 6f1078606e bump after dealing with all things Benny had Coverity find
remainging CIDs not listed are either

• false positive (bug in coverity)
• intentional (possibly with lint override coverity doesn't parse)
• VLA (XXX find out how to mix C99 and ANSI VLAs)
• things flagged as possible resource leaks I have no idea about
  (no biggie though, and only in error cases I think)

tg 3125146b43 Fix typeset issues (LP: #993847)
This was actually more evil:
• use a recursive function to display blocks in reverse order,
  so that local variable values overwrite global ones
• add array support to typeset -p (from typeset -p -)
• display 'set -A varname' line before setting values, for -p
• if -p got arguments, only display those (from the innermost scope)

Also, the usual amount of code cleanup…

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 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.

tg 2539450588 fix regression in jaredy’s security patch introduced in R35b
(cid 100487B467E068A55D6 and 10048949D196A7C1390) discovered
by Jb_boin: time with a not-TCOM subtree would now trash its

tg 34036ec32e MSYS implies -DMKSH_ASSUME_UTF8=0 and thus can skip the test that’d fail 2012-01-03 01:40:15 +00:00
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
has wandered outside the !INCLUDES_ONLY block with the compile-time
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
