tg 0b6afea352 introduce macros for malloc, realloc, free to hide them from mksh
no code may henceforth use memory (de-)allocation functions directly
use these macros, porters can change them for abstraction
2011-03-05 21:43:18 +00:00
tg a796512040 • more comment and int→bool cleanup, add and improve some comments
• in interactive mode, always look up {LC_{ALL,CTYPE},LANG} environment
  variables if setlocale/nl_langinfo(CODESET) doesn’t suffice
• add the ability to call any builtin (some don't make sense or wouldn't
  work) directly by analysing argv[0]
• for direct builtin calls, the {LC_{ALL,CTYPE},LANG} environment
  variables determine utf8-mode, even if MKSH_ASSUME_UTF8 was set
• when called as builtin, echo behaves POSIXish
• add domainname as alias for true on MirBSD only, to be able to link it
• sync mksh Makefiles with Build.sh output
• adjust manpage wrt release plans
• link some things to mksh now that we have callable builtins:
  bin/echo bin/kill bin/pwd bin/sleep (exact matches)
  bin/test bin/[ (were scripts before)
  bin/domainname=usr/bin/true usr/bin/false (move to /bin/ now)
• drop linked utilities and, except for echo and kill, their manpages
• adjust instbin and link a few more there as well

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 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 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 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)
2010-09-14 21:15:11 +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 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
2010-07-17 22:09:40 +00:00
tg ad98b9fc4a compatibility: stick “set ±o arc4random” around for a bit longer,
until R40 is definitively out (so there MAY still be an R39d)

this commit can easily be reverted in its entirety later, when
Build.sh’s compatibility for “-combine” &c. is removed too
2010-07-13 13:07:58 +00:00
tg 4cbb5a9d46 to speed up mksh, get rid of arc4random(3) uses and use the LCG always;
depend on ASLR for seeding

tg 4eb17f8752 remove some more of this ugliness 2010-01-29 09:34:31 +00:00
tg 0c94277ccb To solve the incompatibility issues between mksh-current, old mksh versions
and vendor pdksh versions, re-introduce FPOSIX alongside FSH. The semantics
are now:
‣ set -o posix ⇒
  • disable brace expansion and FSH when triggered
  • use Debian Policy 10.4 compliant non-XSI “echo” builtin
  • do not keep file descriptors > 2 to ksh
‣ set -o sh ⇒
  • set automatically #ifdef MKSH_BINSHREDUCED
  • disable brace expansion and FPOSIX when triggered
  • use Debian Policy 10.4 compliant non-XSI “echo” builtin
  • do not keep file descriptors > 2 to ksh
  • trigger MKSH_MIDNIGHTBSD01ASH_COMPAT mode if compiled in
  • make “set -- $(getopt ab:c "$@")” construct work

Note that the set/getopt one used to behave POSIXly only with FSH or
FPOSIX (depending on the mksh version) set and Bourne-ish with it not
set, so this changes default mksh behaviour to POSIX!

tg a09f05e77a /me is annoyed
I read, IIRC in the Cederqvist, that 'cvs tag' sets a sticky tag onto
the cwd… it doesn’t, apparently. (I actually like it better this way,
but one needs to know!)
2009-11-28 14:28:03 +00:00
tg 883d9d99b3 switch ${%foo} to wcswidth-like behaviour – slightly problematic, and
the “set +U” case isn’t even handled

committed to branch because I’d like to get more input on this, for now

moved to early)
• allow ‘-T’ for MKSH_SMALL too, the installer needs it

tg 6fcacf577d make tab completing filenames with ':' '=' '$' '`' work as well as
others (colon and equals sign need to be simply escaped, while dollar
sign and accent gravis need double escaping like opening square brak-
ket did back then); add = to C_QUOTE to simplify (doesn't break any-
thing) and sort these strings asciibetically while here

tg dc98ec23a6 do not use PATH_MAX on GNU/Hurd (even if it *was* defined), but use
some glibc-only functions that don’t require its use instead

tested on gnubber, where (admittedly) sysconf(_PC_PATH_MAX) == 1024…

tg 33b9f8b666 * rename "set -o posix" (FPOSIX) to "set -o sh" (FSH) because it's not
just a "somewhat more POSIX" but also a "/bin/sh legacy kludge" mode
* consistently capitalise POSIX and SUSv3/SUSv4 (same as AT&T ksh) and
  Bourne shell
2009-10-02 18:08:37 +00:00
tg 1dfb13b603 change undef/def MKSH_NOVI into 0/1 MKSH_S_NOVI flag (with more to come:
MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis-
abled language features), which can be set to 0 despite MKSH_SMALL being
defined to re-enable the Vi command line editing mode (which I wouldn't,
but fits into the general mastermind scheme)
2009-09-24 17:15:33 +00:00
tg 588921333e more of this:
• shell flags are now handled in one single place (sh_flags.h)
• sync comments (between enum and array) and manpage with reality
• FMONITOR is now no longer needed for Hartz IV shells

tg 758dc5c6fe * improve CPPFLAGS vs #define handling again: do not touch CPPFLAGS from
Build.sh but use 'if defined(PRECOND) && !defined(TOBEDEFINED)'if possible
* for all of the source code, drop annotations "imake style" (if we check
  for specific OSes, bad, instead of using mirtoconf checks proper) and
  "conditions correct?" (if I'm not entirely sure if that #if catches all
  cases and no false positives) where I can see it by grepping immediately
* bump mksh patchlevel
* refresh Makefiles

tg 16c47bbe91 fix bug exhibited by t0000-basic.sh introduced in R38 shortly before the
