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)

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)…

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

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

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…

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!

eafe88aa74 • overhaul handling of special variables
• use a combination of the one-at-a-time hash and an LCG for handling
  the $RANDOM special if !HAVE_ARC4RANDOM instead of rand(3)/srand(3)
  and get rid of time(3) usage to reduce import footprint
• raise entropy state (mostly in the !HAVE_ARC4RANDOM case though…)
• simplify handling of the $RANDOM_SPECIAL generally
• tweak hash() to save a temp var for non-optimising compilers
• some int → mksh_ari_t and other type fixes
• general tweaking of code and comments

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

c8955138ec • avoid calling arc4random_pushb for inheritance and other redundant items;

a59d14b565 further optimise and simplify the handling of $RANDOM, reads and writes
to it are now either arc4random or rand/srand, but srand retains the old
state; set +o arc4random is no longer possible, but if it's there we use
arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special
variable handling too and fix a few consts and other minor things

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,

  smaller, although we have a new implementation of the oaat hash
  function, alongside the old one, now) and pushb only if needed
