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)

bb7a720a00 for now, until we really use kt*() otherwise, ifdef out tablep/hval 2009-08-28 20:38:43 +00:00

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)

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

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.

6b2ad96bac some rather mechanical KNF, now that style(9) clarified on the status
of sizeof() as a function-like unary operator; use parenthesēs around
sizeof and return args consistently too

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

31d1499219 * back out almost all of the memory allocator related changes, as aalloc
was hard to type and hard to fix, galloc is also hard to fix, and some
  things I learned will probably improve things more but make me use the
  original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here

c0703f5f26 if MKSH_SMALL and HAVE_ARC4RANDOM, there is no need to use rand()/srand(3)

4230cf91de thinko: multibyte characters are not always 1 column wide 2008-05-02 18:55:37 +00:00
tg
9b62cf15bf • more unsigned → unsigned int
• more int → bool
• more regression tests: check if the utf8-hack flag is really disabled
  at non-interactive startup, enabled at interactive startup, if the
  current locale is a UTF-8 one
• make the mksh-local multibyte handling functions globally accessible,
  change their names, syntax and semantics a little (XXX more work needed)
• optimise
• utf_wctomb: src → dst, as we’re writing to that char array (pasto?)
• edit.c:x_e_getmbc(): if the second byte of a 2- or 3-byte multibyte
  sequence is invalid utf-8, ungetc it (not possible for the 3rd byte yet)
• edit.c:x_zotc3(): easier (and faster) handling of UTF-8
• implement, document and test for base-1 numbers: they just get the
  ASCII (8-bit) or Unicode (UTF-8) value of the octet(s) after the ‘1#’,
  or do the same as print \x## or \u#### (depending on the utf8-hack flag),
  plus support the PUA assignment of EF80‥EFFF for the MirBSD encoding “hack”
  (print doesn’t, as it has \x## and \u#### to distinguish, but we cannot use
  base-0 numbers which I had planned to use for raw octets first, as they are
  used internally): http://thread.gmane.org/gmane.os.miros.general/7938

c1c939e340 • fix memory leaks found by coverity
from netbsd via oksh
  we had the NULL pointer deref already fixed
• avoid a bogus not-setting the return value of edit.c:x_file_glob()
  introduced by the above change in oksh
• escape ? as well (but not ] because that’s wrong)
  reminded by cbiere@netbsd via oksh
• Unsetting a non-existent variable is not an error. See
  http://www.opengroup.org/onlinepubs/009695399/utilities/unset.html
  report from Arkadiusz Miskiewicz; fixed based on
  http://cvs.pld-linux.org diff via oksh but modified slightly
• Be more smart waiting for input for non-interactive scripts.  Fix
  based on a diff from debian:  see their bug#296446 (via oksh)
  modified slightly
  this also fixes cnuke@’s “mksh busy loop” problem, for which I never
  received a bug report, but the Debian bug page contains a set of two
  scripts to reproduce this before (and no longer after) this commit
• some KNF

0989f7da67 Fix for Coverity CID#2: false bug, but still a problem.
Analysis:
internal_errorf(int, fmt, ...) was only a __dead function if the int argument
was non-0, which the Prevent probably was unable to follow. Change all uses of
internal_errorf(0, fmt, ...) to internal_warningf(fmt, ...); change the pro-
totype of internal_errorf() to internal_errorf(fmt, ...) and all remaining
uses remove the non-0 int argument; add __dead to internal_errorf() proto;
flesh out guts of internal_errorf() and internal_warningf() into a new local
function for optimisation purposes.

Some whitespace cleanup and dead code removal (return after internal_errorf(1))

83c2ee87f4 • remove strcasestr.c, use home-grown implementation¹, call it stricmp,
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
  that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
  only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
  to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version

¹) side effect from creating API-correct cstrchr, cstrstr, etc.
   uses goto so it must be better ☻

tested on mirbsd-current via both Makefile and Build.sh
