tg cc8caf2cf9 add a sleep builtin that can deal with fractions too 2011-02-11 00:41:38 +00:00

tg 8b73363c20 query for select(2) in preparation of sleep and read-with-timeout builtins; ualarm(3) and friends are too awkward to use so we ifdef these builtins on select support ☹ 2011-02-09 19:32:26 +00:00

tg d158038191 Limit history file size to 1 GiB for sanity (especially considering struct stat.sb_size is sometimes unsigned, sometimes signed, and sometimes larger than long, ugh…) 2011-02-09 15:08:01 +00:00
tg 5161342b9b fix warning about signed vs. unsigned comparision and potential truncation error 2011-02-09 13:08:27 +00:00
tg 4e0f597b5d fix prev-hist-word again, thanks Jörg-Volker Peetz 2011-02-09 13:08:18 +00:00
tg d4658a569e refactor code to be able to track whether we have a parameter substitution 
or a “proper” glob expansion; if there’s a dollar, but not a glob, refrain
from appending a space later (LP: #710539)

tg 1c4aab3a3e when setting a UTF-8 locale, also set -o utf8-mode 
since we might start on e.g. GNU/Linux with a system-wide C locale

tg 45d99b9ec9 Scan for existence of <sys/file.h> which is not ubiquitous; allows 
klibc-mksh (despite no hope to get a signal of a job) persistent history

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
 2010-09-19 19:28:23 +00:00
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
 2010-09-14 21:26:19 +00:00
tg 08862021ee add size optimisation hacks by me from Android except ifdef’d 
(note, I’d prefer everyone to keep IDSTRINGs around though)
 2010-09-14 21:15:11 +00:00
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…

recognise "--", costs us 20 .text 0 .data 0 .bss

tg 07b97d5444 document workaround for the $(…) parsing bug 2010-09-05 19:12:24 +00:00
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)
 2010-08-28 20:22:24 +00:00
tg 3747722db4 improve string pooling: saves 316 bytes in .text 2010-08-28 18:50:58 +00:00
tg d09fd67299 make cat an mksh builtin, for things like here documents 
if any options are given, the external programme is invoked instead
