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)

noticed by Gábor Gergely in irc, thanks!

tg de9fe12a4c use a more common/generic routine for TIOCGWINSZ;

after them (even if not tty_fd)

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)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here

tg 042086e49e rename utf8-hack to utf8-mode (use set -U or set +U instead, anyway)
and announce less hackish things

tg a19bf7253a * sh.h: note that file descriptors SHALL be <100
* syn.c: fix bashiop-4 regression test; failed due to me using a
  simple string when a wdstring was expected, sorry; the new code
  assumes file descriptors take up a maximum of two characters

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 c0703f5f26 if MKSH_SMALL and HAVE_ARC4RANDOM, there is no need to use rand()/srand(3)
ever, since MKSH_SMALL is not required to be as close to compatibility as
normal/generic shells; we can also get rid of time(3) calls

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())

tg 65b1923b61 build warning-free with LLVM+Clang on MirBSD itself
$ (CCC_LD=mgcc CC=ccc sh Build.sh -r && ./test.sh -v) 2>&1 | tee log
Total failed: 2 (as expected)
Total passed: 278

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

tg 88d7b7d08b • rewrite code to no longer use statements-as-expressions
• optimise a little
• Build.sh: remove HAVE_EXPSTMT test

ahoka 776cc76ccb Add check for the nice(3) system call.
It may be not implemented on some plaforms, though it's usually present.

Required to compile on Haiku as of 2008 October.

tg 8230c9d8ae • do not use __typeof__ even if we have statements-as-expressions, to
please pcc, prompted for by Anders “ragge” Magnusson, problem spotted
  originally by Adam “replaced” Hoka
  ⇒ rewrote x_bs2() and utf_backch() into a combined x_bs3() function,
    since these are never used in any other way
• whitespace cleanup, while here

tg 331b45af7d • OSF/1 may not have MAP_FAILED defined either
XXX mmap() works only on devices on some DEC OSes, not on files, so,
  XXX instead, it were best to disable it altogether
• bump date
2008-10-24 19:54:23 +00:00
tg 0c2de1902c • change mksh to only then behave more POSuXish when called as /bin/sh or
“-sh” if -DMKSH_BINSHREDUCED was passed during compilation, for example
  for Debian, but d̲e̲f̲i̲n̲i̲t̲i̲v̲e̲l̲y̲ n̲̲o̲̲t̲̲ for MirBSD™
• split up regression test to force this behaviour
• remove the gunk from our MirBSD™ startup scripts again
• mention arc4random.c changes on website, sync clog, warn packagers

tg 2fc9fb99d7 when doing a history search (^R), restore old input line on
abortion (^G – ^C is SIGINT and doesn’t work like this, but
that’s actually good IMO)

prompted by enquiry about the Emacs editing mode by <smultron:#MidnightBSD>

tg 9be489ea90 use less stack storage, prefer .bss storage (saves us a memset() call)
and .data instead of another initialisation; this was prompted by a bug
in scan-build (the value can never be NULL, but it doesn’t realise it),
although this doesn’t fix it, but less stack usage is always good
2008-10-15 10:25:01 +00:00
tg c11187f993 fix some of the things scan-build[1] found (but not some false positives)

tg 37934a07cf fix prodded by cnuke@ for AIX with IBM xlC 7.0:
fool the compiler into not doing static bounds checking when we do
one-past-the-array-boundary pointer assignments for cases where the
only accesses are like (*--pointer); bump version

tg 5d9e4c9e16 unbreak MKSH_SMALL after x_histp related changes 2008-10-05 16:06:43 +00:00
tg 27ee1866fe implement Message-ID: <20081004171903.GA14184@boetes.org>
in a somewhat hackish way, and it’s still quite different from zsh,
but probably closer to a desired functionality

XXX this makes state by abusing 「modified」 and 「xmp」 (“the mark”).

tg b65a7f7f9e bump mksh patchlevel for today’s sorta-tested half-done changes, with more
to follow (see <Pine.BSM.4.64L.0809201417560.22066@herc.mirbsd.org>), as I
probably am not going to hack any more tonight

tg 8a853f24be • bring back automatic turn-on of FPOSIX if called as sh/-sh
‣ only if !MKSH_SMALL
  ‣ add appropriate regression test
• if FPOSIX is set, do not close fds > 2 on exec, Debian #499139
• add appropriate regression tests for keeping fds private or not

tg 977237ad14 • merge vi_reset() and edit_reset() into x_vi() to allow for following:
• fix vi mode (which, however, is officially orphaned) multi-line $PS1 by
  using a similar algorithm for prompt skipping as emacs mode (changing
  the meaning of prompt_trunc variable and using prompt_redraw, just even
  more efficiently than vi mode); reported by asarch via IRC
• fix multi-line prompts if last line is “too large” by using emacs mode
  algorithm of just internally appending a newline, while here ☺ this even
  saves us having to re-add the prompt_skip variable…

WARNING: this is only barely tested, as almost nobody ever uses vi mode
⇒ test yourself, there may be bugs (e.g. off-by-ones); already known is
  that the vi input line editing mode is NOT multibyte safe…

tg 06b83a8df8 600 bytes more for the small version aren't worth it; it looks
