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
and feature request provided by wbx@ (Waldemar Brodkorb)

tg b90007d784 • Build.sh, strlcpy.c: gcc-current conversion &c. warnings cleanup
• histrap.c, lex.c, misc.c: get average stack frame size to <= 768 bytes

tg 9179c10119 pgas mentioned ksh93 does [[ $foo ]] (ipv forced [[ -n $foo ]])
and it actually REDUCES code size to allow it as well; mention
in the manpage that it’s merely unportable (and of course exe-
cution time differs); sync clog

tg ae8d54284a commit Syllable-related improvement: simplify p_time 2009-05-20 10:10:02 +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)

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

tg 7641ea6d07 optimise the “regression test” ☺ 2009-05-16 16:03:41 +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

  checked is right there

tg 1b3e4a3a2e when outputting in a row x column formatted way, but the available space
on the screen is not enough for two columns, just output the text line by
line, instead of trying to format it; gets rid of superfluous empty lines
if we did not even have space for one column on the screen (x_cols)

tg 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)

* optimise, polish
* regen Makefiles

tg 330948eafd add a test case for the recursion limit fix 2008-12-02 12:48:16 +00:00
tg 4897682502 Alias expansion has a recursion check which tries to break the cycle if
encountered. However, when reading end of input, the source type is set
to SEOF while popping, whereas the recursion check code only checks for
an SALIAS type.

Fix: add a new SF_HASALIAS flag; change u.tblp from being valid if type
is SALIAS to being valid if SF_HASALIAS is set; set SF_HASALIAS for the
created SALIAS sources; set SF_HASALIAS and u.tblp when creating SALIAS
whose next is SEOF on the SEOF source as well.

tg 3c1e46ee4d prepare for aalloc.c, which I have just written myself, as an area-based
allocator using malloc and free, with mmap malloc and omalloc in mind,
not counterfeiting its security measures such as guard pages, and having
some of our own, e.g. XOR random cookies, optional mprotect, etc.

zero cost (for we have arc4random())

Total passed: 278

Just the result is huge, and we could of course build to intermediate
byte code to optimise globally…

tg 446e019c07 the QNX /bin/ed problem is worse than thought; use a new mechanism,
because categories in check.t are OR’d:
• no-stderr-ed disables the newish-ed tests (tried using testcase)
• stdout-ed enables the oldish-ed tests (variable, if the above
  testcase succeeds, it’s added, but QNX overrides the variable)
2008-11-08 17:36:35 +00:00
tg 6e490218ca On QNX, do not run the tests involving /bin/ed at all, because it appears
oldish but is in fact broken. However, if /bin/ed is MirBSD ed(1), these
actually pass.
