d57a033057 • no longer use <stdbool.h> even if it’s available
• ensure that bool/true/false are cpp macros, overriding any pre-defined
• document the requirement that tobool(x) must map any-type 'x' into bool
• document the requirement that a bool must only be true or false, and
  that it (tobool() rather) must have an identity mapping to 'short'
• possibly fix ksh_func for/and fpFUNCTf – maybe spotted by cnuke@

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)…

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

8d8ee0cc6a ironhead reported in IRC that some Cygwin guys (not he, he’s just the
packager) complain that mksh collapses two leading slashes; IIRC POSIX
has a clause for UNC pathnames, so stop doing that, plus add a test

af53a7d16a • speed optimisation: drop SF_FIRST flag, factor out skipping the
UTF-8 BOM instead (UTFMODE has a separate value now for activated

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)

f8659785ac • add a tree debugging dumper #ifdef DEBUG
• use shf_putc (macro), shf_putchar (function) ipv tputc

• plug another bug in the tree code – '\' → "\\" (backslashes must be
  escaped inside double quotes, too)
• adjust testsuite (and, I _had_ wondered…)

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?

c995f7ca98 I thought of making COMSUB pass a pointer to the struct op *t->left around
instead, but the parser for the so-called “backticks” (U+0060) still emits
plaintext COMSUB wdstrings, and the evaluation code emits plaintext if the
code is not run (‘-n’ option), so it’s not worth the effort and memory ma-
nagement issues, even though it _would_ optimise the most common case…

Bump version numbers, sync regression tests; add one testcase from the old
webpages too. Sync manpage, this now works, but keep the workaround in, as
“portability issue” with slightly changed wording.

Also, /bin/sleep must be used in one manpage example if sleep is built in.

f3dbbe3f0c split malloc_os and friends further into
• functions called by mksh’s grouping memory allocator
• functions called by mksh code itself

the latter may be changed to call the internal grouping allocator,
if a porter so desires (but if this were recommended, the code in
question would already do so, so…)

0b6afea352 introduce macros for malloc, realloc, free to hide them from mksh

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

  string pooling for T_synerr, which is used in place of a format string

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
