tg 27387673a4 new MKSH_DISABLE_TTY_WARNING for ports that just can’t help it
TODO: add_cppflags this automatically in the TARGET_OS switch for some
2012-05-04 22:34:51 +00:00
tg e6ace01f12 last parts of Coherent patchkit: O_ACCMODE and termio 2012-05-04 22:18:27 +00:00
tg 7beac6668d provide for Coherent not having gettimeofday(2), imake style (bad, but this is not for others to use without a second thought anyway) 2012-05-04 21:47:04 +00:00
tg 2d31aca859 more int→bool while trying to let ^D output CR+LF (which shan’t be, oh my…) 2012-05-04 21:15:34 +00:00
tg 5780bc5eb7 new MKSH_NO_CMDLINE_EDITING to disable command line editing in its entirety
mainly for the Plan 9 port though it may also help the WinAPI variant,
other porting efforts, as well as a new project I cannot say yet
2012-05-04 20:49:08 +00:00
tg 5eea59ad57 rewrite maketemp() obsoleting tempnam(3) and mkstemp(3) external deps 2012-04-14 16:07:48 +00:00
tg 4a89ae1cd0 drop the need for strcasestr: just uppercase a copy and compare with uppercased 2012-04-06 12:59:28 +00:00
tg e67b98e21b use _setjmp/_longjmp on NeXTstep: its Intel port always restores the signal mask on siglongjmp, which we never have 2012-03-31 17:30:00 +00:00
tg b82db8764c only pull entropy from glibc pointer guard if glibc is actually there 2012-03-31 17:08:52 +00:00
tg 95a2c63096 • implement fcntl(2)-based advisory locking as an alternative iff flock(2)
is not found, from a suggestion by RT (LP: #912691)
• try harder (in a loop) to acquire a file lock if the locking mechanism
  documents EINTR is a possibility (fcntl always, flock on Linux not .Ox)
• use -std=c99 not -std=gnu99 if it must be at all
2012-03-27 22:36:53 +00:00
tg 87654270ab fix regression w.r.t. TTY and external programmes:
• release the TTY after the initial change_winsz()
• since we release it, we can skip initialising tty_state, too
2012-03-25 14:28:14 +00:00
tg 5dd5edea1a lewellyn found QNX also doesn’t have a struct timezone ⇒ just DROP it! 2012-03-24 22:11:41 +00:00
tg c6b498d4fe meh, hit a regression again 2012-03-23 22:36:23 +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 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…

tg ebb8bed911 fix segfault due to limit of hashtable entries (global variables) discovered by Jb_boin: unlimit to 2^30 minus epsilon 2011-06-04 16:42:31 +00:00
tg d1b8800ee8 • AIX: display OS version better (tested on 5.3 by cnuke@)
• IBM XL C: display version better (tested on V7.0 by cnuke@)
• do not 'IFS=: read nr name', Cygwin 1.7 dash fails it
• disable cd-pe, glob-range-3 on Cygwin (the former cannot
  succeed because the mv fails, the latter fails from 1.7 on)
• mark heredoc-tmpfile-8 as need-pass: no
• apply __attribute__ only to a function prototype, not to
  the body (even if static), since xlC fails that
• bump version to R40 (beta)

tg e8ea9954aa • Implement http://austingroupbugs.net/view.php?id=367 and align things
a bit more with POSIX and the other shells

I considered http://austingroupbugs.net/view.php?id=253 but the use
of bi_errorf() is interesting, especially as it’s often enough a
noreturn function, and funnily enough, 'cd -P /foo' returns 0 while
'chdir -P /foo' fails (so idk where to put -e)…

tg 5239e8ea4c actually, we need the android lsmod to be a builtin not an alias… 2011-03-16 20:56:33 +00:00
tg 1c22b3cc48 oops 2011-03-16 20:43:34 +00:00
tg 79c6d6043e • introduce a virtual TARGET_OS=Android that just sets a check category
and switches to the TARGET_OS=Linux
• introduce android as regression test suite category
• add an android specific standard alias
• clean up redundant ‘-o sh’ arg in a few checks
2011-03-16 20:26:36 +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 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 6a941a3c39 fix UWIN: don’t close fd #3 (also, int→bool) 2011-02-27 19:29:32 +00:00
tg 0b57abd4d3 • add -u option (POSIX: unbuffered ⇒ nop) to the built-in cat
• PIPESTATUS now supported (like bash 2) whose last member
  may actually differ from $? since the latter may not be the
  result of a pipeline partial command
• add regression tests, documentation, etc.
2011-02-18 22:26:13 +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 865b267dbf drop suspend alias in Android too 2011-01-21 21:07:11 +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 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 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
