tg bfe7d78d40 bring back ${ foo;} sans dot.mkshrc patch, using a temporary file, and as experimental feature 2012-10-22 20:19:18 +00:00
tg e2d1f3bf99 related to LP#1025843 fix tab completion for tilde
this code is insane, who wrote globbing and expansion for mksh’s
predecessor must have been on very interesting drugs
2012-08-24 21:15:42 +00:00
tg 42ac0dc08e second attempt at getting '$FOO/b*r/baz' tab-completed right,
plus the beginning of the tilde fix… do not use, this is fucking
impossible to get right, but I’d like an archival commit
2012-08-24 20:57:46 +00:00

tg 058e7f8ed4 do implement quoting, as ${foo@Q} though, as hommage at mirmake
dedicate this “release” to Andi
and use tomorrow’s (UTC) day for version, to cover up my debian fuckup
2012-07-20 23:22:13 +00:00
tg 0c3aed77e0 fix trimming with positional parameters (Closes: #48453) 2012-06-28 20:03:20 +00:00
tg 252a7ce68f Coverity 703479: add missing /* FALLTHROUGH */ 2012-06-24 19:36:27 +00:00
tg fef3808126 more symlink(7) nonexistence support code 2012-05-04 22:05:02 +00:00
tg 5204e7cc4f after discussion with ciruZ, switch mksh from NZAT to NZAAT fully
to get rid of the bias introduced by making the hash never zero

… he also pointed out a memory (heap) usage optimisation… which
may impact code size a bit though as I’d need to pass an additional
argument on hashtable function calls… or, forgo the benefit of not
having to pointer-align the key in the structure, which can be as
much as 3/7 octets per item, heap storage… OTOH the saved space is
4/8 octets per not-allocated item, possibly some code (use of an
multiply-add opcode), but the function call overhead/cost would
possibly be quite a bit… I guess I’ll have to measure…

tg a4eb9795de fix indentation mishap 2012-04-06 14:07:52 +00:00
tg cf75e7b6ce couple of minor/cosmetic fixes from RT’s compile farm:
• promote SCO OpenServer and UnixWare to !oswarn
• omit trying -O2/-O on OpenServer 5 and USL C
• cast mksh_ari_t to int, mksh_uari_t to unsigned int for printf
• skip ulimit-1 on syllable (which is still too broken)
• write ((mksh_ari_t)-2147483648) ipv UB ((mksh_ari_t)1 << 31)
  and add a comment that that is actually meant
• rewrite functions returning !void ending in NOTREACHED
  so they’ve got a jump target returning an error at the
  end, to aid older compilers and just to be safe
• cast struct stat.st_size to off_t or size_t explicitly when needed
• shorten struct env by two bytes and an alignment, at least

also, optimise control flow and fix more paren matching cases
2012-03-29 19:23:01 +00:00
tg 16ac73b074 g/c magic definitions for simple chars (as opposed to e.g. tokens/lexems)
some (such as NOT) were already gone; this should unconfuse; most were
unused anyway…
2012-03-27 22:58:39 +00:00
tg 21c15c0b8f huh, I thought I had extended ${parameter@#hash} already; make it so now,
but not yet things like ${parameter@Fi} (1 if integer, 0 otherwise), etc.
also bump patchlevel and © years in recently changed files
2012-03-23 23:25:30 +00:00
tg 3795e667c5 drop use of the NOT macro, [^foo] ≠ [!foo] anyway, and we’re not gonna change that 2012-03-23 20:07:13 +00:00
tg 0b3d21702a fix ifs.sh; anonymous submission (mkt?), 10x 2011-12-16 20:03:12 +00:00
tg 0695039dc0 fix stateptr-underflow; really do call fastbox regression checks; bump vsn 2011-11-26 00:45:21 +00:00
tg 904dc3dae4 oh lookie, oksh fixed something we did in 2007… ⇒ pointless rcsid-in-comment sync 2011-10-11 19:06:07 +00:00
tg 9782f6b4d1 • access(2) is broken in at least kFreeBSD 9.0 as “modern” OS, so bring
back the wrapper code as well as refactor most other code calling it
• apparently, names can’t end in ‘_’ or contain ‘__’ anywhere…
2011-09-07 15:24:22 +00:00
tg 577c918beb patch most of Jerker Bäck’s concerns out, unless not applicable 2011-08-27 18:06:52 +00:00
tg b89c144344 fix vstrchr like use of cstrchr 2011-07-02 17:57:02 +00:00
tg c133d423df ACK found a missing "static", gcc on Minix found a missing cast; add more type size checks 2011-06-12 14:45:34 +00:00
tg 69f98bca9a • fix wtf(1) by keeping the paren in ${foo#\(} properly escaped in COMSUB
• merge tputS and wdstrip_internal
⇒ net save: 604 .text 0 .data 0 .bss (MirBSD/i386)
2011-05-02 22:52:54 +00:00
tg e19d8612ad another Debian workaround for /bin/sh: don’t pattern in trims 2011-03-28 08:27:09 +00:00
tg d07bacd44a • fix check for empty pattern in ${foo/bar/baz} expansion: the
character anchoring the pattern (‘#’ or ‘%’) must be skipped
  if one was used; fixes “BLA="#test"; echo "${BLA//#/}"” busy
  looping (due to null pattern) found by Jb_boin
2011-03-17 21:57:50 +00:00
tg b7824978ad RCSID sync with openbsd, one we had already, one Okan Demirmen stole
from mksh (but attributed, so it’s okay, considering the amount of
patch is not large enough to warrant copyright stuff)
2011-03-16 20:31:33 +00:00
tg af53a7d16a • speed optimisation: drop SF_FIRST flag, factor out skipping the
UTF-8 BOM instead (UTFMODE has a separate value now for activated
  during BOM skipping)
• parsing a COMSUB now skips UTF-8 BOM, too, but only temporarily
2011-03-13 16:03:54 +00:00
tg 2a3d4db123 lint is your friend 2011-03-13 01:20:25 +00:00
tg a3c79ad771 now fix that segfault and other bug from yesternight
do it like ksh93 though, not like bash and zsh
2011-03-12 23:06:43 +00:00
tg 75db4cdb56 • back out the EXPRSUB change
• optimise some code
• split testcase into two, one with expected-fail
2011-03-12 23:04:48 +00:00
tg 17dbd3bd83 • make EXPRSUB not initiate an ASCIIZ string any more but a wdstring
(token stream, lexer output / parser input), EOS terminated, let
  SASPAREN use the same lexing as SBASE (e.g. COMSUB recursively)
• make wdstrip recursive
• fix processing of COMSUB in wdstrip
⇒ pass comsub-1 test
• expose another debugging function
2011-03-12 21:41:15 +00:00
tg 5f8075fc82 introduce a tobool(cond) abstraction¹ and switch bool to char if !stdbool.h
① currently: ((cond) ? true : false) but (!!(cond)) and casting to bool,
  the latter only if stdbool.h, would also work – which performs best on
  (and across) all supported systems?
2011-03-07 20:30:41 +00:00
tg da9d0f3d97 ${foo@x} is now special-expansion for values of x, defined for now:
‘#’ = hash of $foo
2011-01-21 22:25:34 +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 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 7c91e018f4 • merge printf from OpenBSD
• deactivate %a and %A since our libc doesn’t have it
• rewrite the mksh integration code to use shf instead of stdio, removing
  floating point support always in the process, as shf doesn’t support it
  ⇒ saves 11114 (6706 text, 168 data, 4240 bss) with dietlibc on Debian
• fix -Wall -Wextra -Wformat -Wstrict-aliasing=2 for gcc (Debian 4.4.4-7)
• fix these and -Wc++-compat for gcc version 4.6.0 20100711 (experimental)
  [trunk revision 162057] (Debian 20100711-1) except:
  – a few enum warnings that relate to eglibc’s {g,s}etrlimit() functions
    taking an enum instead of an int because they’re too stupid to adhere
    to POSIX interfaces they design by themselves
  – all “request for implicit conversion” involving a "void *" on one side
• tweak the manual page somewhat more

tg 549c510269 related to 1004BF041CB522EEEE3 ${foo[*]} is a vector too; add testcases 2010-05-16 19:17:42 +00:00
tg f24e2c80a9 disallow some more kinds to trim a vector; Debian #581867 2010-05-16 19:04:42 +00:00
tg 6e98fbe27b Fourth time’s a charm… another bugfix related to the commitids

to unbreak kwalletcli
2010-04-20 09:10:07 +00:00
tg 14ea7e9038 draft a testcase to understand the problem fixed by cid 1004BBF77B81D30DA7C
and make it actually work: the OpenBSD fix failed since 1004BBDD84556472D84
2010-04-09 19:16:31 +00:00
tg 3461fcdf20 apply oksh bugfix for my bugfix they applied in oksh… ugh…
from halex@o: modified to handle the case when the expr is quoted

no difference in check.t or ifs.sh though…
