tg 7cb17b16a0 more int→bool 2009-08-28 21:04:18 +00:00
tg 9b8d4023fa … but since I liked the bonus of having the hval stored so much, merge
it with the array index; var.c says that
│ 1244         /* The table entry is always [0] */
so that we can have a special flag and a union which stores hval for
the table index, the array index otherwise (coïncidentally *hint hint*
they have the same size)
2009-08-28 21:01:27 +00:00
tg bb7a720a00 for now, until we really use kt*() otherwise, ifdef out tablep/hval 2009-08-28 20:38:43 +00:00
tg 4ccdfc8508 much better solution: save tablep and hash value¹ in the struct tbl entry
① also saves time during texpand :D

XXX this doesn’t work well with the current indexed-array implementation
2009-08-28 20:30:59 +00:00
tg 7240c843ce this is a rather stupid diff: give ktsearch/ktenter the capability to
return information needed to do a real ktremove instead of the pseudo
ktdelete operation which merely unsets the DEFINED flag to mark it as
eligible for texpand garbage collection (even worse, !DEFINED entries
are still counted)

tg cd7f3fd836 another int→bool 2009-08-28 19:16:17 +00:00
tg 2cda4dd7bb this wants a size_t (but ssize_t is enough, since order(size_t) elements
is pretty much impossible… I estimate at most a million, but not more
than 16 million, array or keytab entries)

tg ca1f967a45 • use Jenkins’ one-at-a-time hash for mksh keytabs, as it has
much better avalanche and no known funnels
• improve comments
• fix some types (uint32_t for hash, size_t for sizes)
• optimise ktsort()

no functional change, I think

tg 0e1266ef90 While mksh R39 builds fine on MirOS #7s8E on my trusty sparc, pgcc 2.95.3
throws out quite some warnings – fix most of them except most emitted via
-Wconversion; work around some others; discard bogus warnings.

2009-07-30 18:42:31 +00:00
tg 758dc5c6fe * improve CPPFLAGS vs #define handling again: do not touch CPPFLAGS from
Build.sh but use 'if defined(PRECOND) && !defined(TOBEDEFINED)'if possible
* for all of the source code, drop annotations "imake style" (if we check
  for specific OSes, bad, instead of using mirtoconf checks proper) and
  "conditions correct?" (if I'm not entirely sure if that #if catches all
  cases and no false positives) where I can see it by grepping immediately
* bump mksh patchlevel
* refresh Makefiles

more from cid 1004A2D72DD5A4E4B4F tried to be fixed in 1004A300A72701188E3
but I’d appreciate someone who actually uses Vi Mode to test it:

tg 16c47bbe91 fix bug exhibited by t0000-basic.sh introduced in R38 shortly before the
release: sometimes, a “cd -P” would cause memory corruption because lalloc
internal data was overwritten due to accidentally losing a “continue;”

tg da5dc48cd0 implement an extension that an interactive mode input line, when
starting with an ‘!’ exclamation mark at the beginning of a com-
mand (PS1 not PS2), shall have the same effect as the predefined
“r” alias, to be compatible with csh and GNU bash’s “!string” to
«Execute last used command starting with string» – documentation

tg 9179c10119 pgas mentioned ksh93 does [[ $foo ]] (ipv forced [[ -n $foo ]])

cution time differs); sync clog

tg 361dee04f3 laffer1 agreed they will need -DMKSH_MIDNIGHTBSD01ASH_COMPAT in the
short term, but only for /bin/sh – thus recommend to also define
-DMKSH_BINSHREDUCED and make it dependent on FPOSIX

tg 8a2557f846 pcc cought a bad programming idiom I accidentally used
(without realising that it’s a macro expansion, that is)
2009-05-16 19:34:07 +00:00
tg b6ce748064 • remove “#if 0” and “#ifdef notdef” style old debugging code
• expose “#ifdef MKSH_MIDNIGHTBSD01ASH_COMPAT” just in case they decide to
  require it and show it in the ksh version automatically
• sync the use of non-ASCII characters over files (unification)
2009-05-16 18:40:09 +00:00
tg b145ca5c9f • sync distrib/special/mksh/Makefile with bin/mksh/Build.sh and
fix the regression test’s results while here, which have been
  broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
  bian; track down commits in all files of oksh-mirbsd and mksh
  to get correct copyright years per-file, as is BSD custom
2009-05-16 16:59:42 +00:00
tg cc783807d3 this began as a one-word change to the spec (manpage): that
${foo:1:2} operates on characters ipv bytes – which means:
‣ set +U: octets
‣ set -U: MirOS OPTU-8 characters

for consistency I also adapted ${#stringname} to deliver the
length in characters ipv bytes; more may follow; for example
I’d like a way to expose the string width.

you can already get the MirOS OPTU-16 of a character in the
WTF-8 (「set -U」) mode with something like
│ typeset -Uui16 -Z7 x=1#${stringname:position:1}
which will correctly use the PUA EF80‥EFFF mapping for octets.

due to this being an incompatible change, bump to R38

also change the unicode-hexdump sample regression test and
add two news for ${x:1:2} and ${#x} checks in A/W mode ☺

tg e88736b5ef decouple conservative file descriptor use from MKSH_SMALL, with the
new MKSH_CONSERVATIVE_FDS præprocessor flag, because Minix 3, for

tg db6ed8be7c ... and it did in fact require DEC ucode cc to spot this!
gcc, SUNWcc, pcc, llvm-gcc, clang, etc. all didn't say a thing!

now compiles warning-free (testsuite pass) on ULTRIX 4.5 (1986),
and OSF/1 X2.0-8 (testsuite norun: perl missing) has only the usual
bitchings about "volatile sig_atomic_t" because the latter part is
already volatile, but otherwise warning-free compile, works fine

tg 62b28858d4 sync; fold oksh-seterror test into errexit-*; use print not printf 2009-03-22 18:28:35 +00:00
tg b20f49adae patch from oksh (except manpage, I'll merge that later):
pass "xerrok" status across the execution call stack to more closely
match what both POSIX and [18]ksh.1 already describe in regards to set
-e/errexit's behavior in determining when to exit from nonzero return
values.

specifically, the truth values tested as operands to &&' and ||', as
well as the resulting compound expression itself, along with the truth
value resulting from a negated command (i.e. a pipeline prefixed !'),
should not make the shell exit when -e is in effect.

issue reported by matthieu.
