tg 30d8e3934d SUSv4 says trap foo UNKNOWN is not a syntax error, merely exit ≠0. 
Inspired by 673dab8698b0399c967216c02262eaf95361a75c.

tg bdfcdc56c8 introduce MKSH_NOPROSPECTOFWORK which is like pdksh’s JOB_SIGS in reverse, like MKSH_UNEMPLOYED is pdksh’s JOBS in reverse; allows mksh to work (hah! no pun intended…) with klibc (and possibly, Syllable Desktop and Plan 9) for now, until they fix their bugs 2011-01-30 01:35:35 +00:00
tg 07889fb0eb -DIN_MKSH is not used by anything 2011-01-29 19:07:16 +00:00

tg da9d0f3d97 ${foo@x} is now special-expansion for values of x, defined for now: 
‘#’ = hash of $foo

tg 846fbde3b8 add read with delimiter, like AT&T ksh93 (thanks Dave for the suggestion) 2011-01-21 22:00:17 +00:00

tg cc31d86e3b • implement KSHEGID, KSHGID, KSHUID variables by suggestion of Richard K. 
(KSHEUID aka USER_ID already exists)
• simplify, speed up LCG and $RANDOM handling again

tg 7326331f30 RT|Chatzilla said in #!/bin/mksh that MSYS probably does mksh 2011-01-15 21:56:36 +00:00
tg 230f59d064 New functionality: assign here document to string variable directly, 
without cat and temp files. Hacked in Lëtzebuerg ☺

This was the third try. Where to put this was not palpable… same for =(…)
 2011-01-09 21:57:29 +00:00
tg b4948e430f this is a bashism but might be from ksh93 IIRC… still dead ugly as hell! 2010-12-19 20:00:56 +00:00
tg ce160a8155 MKSH_SMALL need not imply !HAVE_REVOKE as default 2010-12-12 14:06:35 +00:00
tg 210608b199 regenerate all wcwidth code from UCD 6.0.0 and related tables, 
and mgk25’s wcwidth.c 5.0 code; add check against 2-byte wchar_t;
optimise libc wcwidth(3) implementation taken from mksh and sync these
 2010-12-11 16:05:03 +00:00
tg beba20ea56 since dot.mkshrc is sourced by interactive shells anyway, and exporting 
PS1 may hurt other shells, do not export it any more

reported by and fix suggestion / affected variables by Frank Terbeck
 2010-11-26 21:08:54 +00:00
tg 27dce9168a change behaviour of argument-less exit in traps to match SUSv4; Debian #599484 (original patch from Jonathan Nieder, thanks!) in a variant that appears to handle nested traps well 2010-11-01 17:29:05 +00:00
tg e57379aab7 regenerate from Unicode 6.0.0 2010-11-01 17:28:49 +00:00
tg 29de79c7bf mknod’s now demoted and only used as special-case builtin, in MirBSD only 
built for the installer, to save time, as the original OpenBSD hack wanted
 2010-10-08 17:56:57 +00:00
tg c37518d509 ouch! \c? is DEL, not \c~ 2010-10-08 17:30:05 +00:00
tg 3365cb8d0f • Build.sh: fix a compiler warning which, had it not been irrelevant in 
a mirtoconf check, would’ve been a real problem on an LP64 platform
• sh.h: work around a bad interaction between -Wformat on gcc and manual
  string pooling for T_synerr, which is used in place of a format string
  in some places
 2010-10-01 19:04:38 +00:00
tg 895e8f584b partial obsd sync: 
- remove some old groff workarounds in SYNOPSIS
- avoid "Op ... Oc" constructions
except where the latter doesn’t work with nroff
 2010-09-24 20:21:43 +00:00
tg e169648b89 while here, change SETUID_CAN_FAIL_WITH_EAGAIN to abort immediately 
by suggestion of Chris Palmer again

tg b0b03a5a75 RNDEBUG showed that using the pushb_fast will have much fewer syscalls 2010-09-19 19:21:20 +00:00
tg 915b30adfe revert part of the “size reduction” diff (zero size change though): 
shellf() implies an shf_flush()…
 2010-09-15 21:08:19 +00:00
tg 667d792d6a • Address concerns of Chris Palmer from the Android security team 
– possible integer overflows in memory allocation, mostly
    ‣ multiplication: all are checked now
    ‣ addition: reviewed them, most were “proven” or guessed to be
      “almost” impossible to run over (e.g. when we have a string
      whose length is taken it is assumed that the length will be
      more than only a few bytes below SIZE_MAX, since code and
      stack have to fit); some are checked now (e.g. when one of
      the summands is an off_t); most of the unchecked ones are
      annotated now
    ⇒ cost (MirBSD/i386 static): +76 .text
    ⇒ cost (Debian sid/i386): +779 .text  -4 .data
  – on Linux targets, setuid() setresuid() setresgid() can fail
    with EAGAIN; check for that and, if so, warn once and retry
    infinitely (other targets to be added later once we know that
    they are “insane”)
    ⇒ cost (Debian sid/i386): +192 .text (includes .rodata)
• setmode.c: Do overflow checking for realloc() too; switch back
  from calloc() to a checked malloc() for simplification while there
• define -DIN_MKSH and let setmode.c look a tad nicer while here

tg 08862021ee add size optimisation hacks by me from Android except ifdef’d 
(note, I’d prefer everyone to keep IDSTRINGs around though)

tg dcbfc48855 ┌──┤ apply Android patch from Jeff Hamilton: 
│Don't alias 'stop' to 'kill -STOP'
│
│Android has already has a stop command used
│to stop the main runtime and the alias
│interferes with testing tools that expect
│stop to kill the runtime.
│
│Change-Id: I02b7efb9203dc39e97f63eb702a54ff79935b316

Although, this is closer to his first patchset and only takes
care of the alias, not the testsuite (which doesn’t run, at
least not out-of-the-box, nicely anyway) using #ifdef ANDROID.

We certainly want a more flexible testsuite…

tg 2c59cc6089 more on the cat 2010-08-28 21:22:24 +00:00
tg 06c6be0a70 shave off another 468 bytes: we’re 300 bytes smaller than BEFORE the 
cat builtin was added now… (also removed utf-8 from source files, in
favour of just ASCII)

tg a0d43a99fd it’s ugly to write a ./stdint.h file if we can instead define the 
types from sh.h; sync clog
 2010-08-24 15:19:54 +00:00
tg 7fdc42cead fix realpath builtin’s handling of (source) pathnames with a trailing slash 
as per POSIX (if a trailing slash is part of the symlink target it fails as
well, like GNU readlink -f does)

tg 14dc6071e7 portable hogwash 2010-08-14 19:55:37 +00:00
tg c187f3089f a tad annoying, when external programmes such as GNU screen are running, 
we don’t get SIGWINCH when the window size changes during the runtime of
that, so, the signal is only usable reliably during editing in the shell
and we re-check the window size before each interactive edit line again
