tg 64afff52c1 winstonw made me discover there is no ELOOP in Plan 9:
http://plan9.bell-labs.com/sources/plan9/sys/include/ape/errno.h
2012-03-26 20:04:05 +00:00
tg 24e8a6996b always keep x_cols and x_lins valid; check once at start including tty init
if we find any, but not later; do not check on every read

⇒ allows changing COLUMNS and LINES (independent of each other, or both)
  for script shells by passing them in an environment setting, even if
  we get a tty; interactive shells still check before each line is read…

reported by the PLD guys, thanks

tg 2cfc3e5c3d mksh R40 Release Candidate 1
Testsuite:
• add new need-pass: {yes|no} attribute, default yes
• exit with 1 if a need-pass test failed unexpectedly
  idea by Kacper Kornet <draenog@pld-linux.org>
• mark utf8bom-2 as need-pass: no
Infrstructure:
• add housekeeping function for making a tty raw
• switch functions with unused results to void
• struct op: u.charflag contains last char of ;; in TPAT
• var.c:arraysearch is now a global function
Language:
• add ;& (fall through) and ;| (examine next) delimiters
  in addition to ;; (end case) as zsh extensions, because
  POSIX standardised on ;& already
• add -A (read into array), -N (read exactly n bytes),
  -n (read up to n bytes), -t (timeout) flags for read
  from ksh93
• allow read -N -1 or -n -1 to slurp the entire input
• add -a (read into array the input characters) extension
  specific to mksh to read, idea by David Korn
• add -e (exit with error if PWD was not set correctly
  after a physical cd) to cd builtin, mandated by next
  POSIX, and change error codes accordingly
Rewrites:
• full rewrite of read builtin and its manpage section
• add regression tetss for most of the new functionality
• duplicate hexdump demo tests for use of read -a
• use read -raN-1 in dot.mkshrc to get NUL safe base64,
  DJB cdb hash and Jenkins one-at-a-time hash functions

tg b91b037e6a we got a decision on pathnames with exactly two leading slashes
thanks, Eric and David!

tg 5f31b8c97a • bring back test -H ifdef S_ISCDF (for HP-UX)
• whitespace, etc.
• bump version for tonight, I’m not gonna hack on c_cd,
  all this pathname stuff is mind-boggling…
2011-03-26 21:46:06 +00:00
tg a55de5f840 • rewrite simplify_path() to keep more in line with do_realpath()
• add regression test to ensure that //foo pathnames are never simplified

tg c2333a7dbd simplify_path: we CANNOT simplify pathnames beginning with //

tg b1d97ea44e temporary patch for Cygwin against cd breaking UNC pathnames
from Chris “ironhead” Sutcliffe
2011-03-26 15:37:19 +00:00
tg 803c51914b • move funcs.c:do_realpath() to misc.c and make it global
⇒ consider merging simplify_path()
• move funcs.c:c_cd() to misc.c
• make misc.c:make_path() static, c_cd() is its only user
  ⇒ mark as obsolete
• tweak misc.c:set_current_wd() to drop ksh_get_wd() argument

should be no code change, but the entire path stuff is a mess…
so expect actual implementation changes or even rewrites shortly
2011-03-24 19:05:49 +00:00
tg 3c41d2b063 fix cast; bump version 2011-03-17 22:09:23 +00:00
tg 2f2fe89157 • write a pattern optimiser and call it before invoking do_gmatch(),
to catch several very slow cases (especially “*@(*foo)” busy-loops
  – spotted by Jb_boin as usual these days ☺) by converting all @(…)
  with one case to drop the enclosing MAGIC(…), and in a second pass
  collapsing adjacent asterisk (‘*’) wildcards
2011-03-17 22:00:45 +00:00
tg a1a5922fc6 • make misc.c(gmatch.c):pat_scan() static and fix int → bool 2011-03-17 21:59:30 +00:00
tg 2a3d4db123 lint is your friend 2011-03-13 01:20:25 +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 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
2011-02-11 01:18:23 +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
2011-01-21 21:04:48 +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 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
2010-07-04 17:33:58 +00:00
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!
