• 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@
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
a mirtoconf check, would’ve been a real problem on an LP64 platform
• sh.h: work around a bad interaction between -Wformat on gcc and manual
string pooling for T_synerr, which is used in place of a format string
in some places
– 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
‣ -combine → -c combine
‣ -llvm → -c llvm -O
‣ -llvm=x → -c llvm -o x
‣ -valgrind → -g²
• new option -v (version)
• new options -c (compile mode³), -o (opt flags), -O (reset opt flags)
• opt flags default to -std-compile-opts (llvm) now
• support⁴ the LLVM dragonegg plugin for GCC
• sync list of removed files (*.bc, *.ll, add missing Rebuild.sh)
① old options still valid but emit a warning
② except this one
③ compile modes are:
• normal
• makefile (-M)
• combine (old -combine, new -c combine)
• dragonegg (new -c dragonegg)
• llvm (old -llvm, old -llvm=*, new -c llvm)
the first two are not settable via -c though…
④ sample use:
tg@seduxbox:~/x$ export PATH=$PATH:/opt/llvm/bin
tg@seduxbox:~/x$ CC='/opt/gcc-4.5.1/bin/gcc-4.5.1 -fplugin=/opt/llvm/lib/dragonegg.so' sh ../mksh/Build.sh -c dragonegg -r
Thanks to «dileX:#grml» for giving ssh access.
now that we use the same name as quiet-by-design autoconf
to please ccache anyway (and no we will not become quiet,
I can't usually get my hand on a buildd's conftest.log)
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)
libc function realpath(3) which may not be available on the target
system; compile the realpath builtin unconditionally
looks fine to me, but review is appreciated; this is (very) lightly
based upon MirBSD libc’s realpath(3) and pdksh’s get_phys_path()
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
the state of the C Præprocessor at configuration time (simple checks, i.e.
set/unset, set+1/set+!1/unset, and more complex checks), including verbose
output; related cosmetics and variable naming cleanup
QNX 6.4 is out, which has a different waitfor() in <libutil.h>, which
we by definition of __NO_EXT_QNX do not want to use. They are in the
process of porting the NetBSD® pkgsrc® repository to it.
The /bin/ed situation hasn’t improved yet though.
• expose “#ifdef MKSH_MIDNIGHTBSD01ASH_COMPAT” just in case they decide to
require it and show it in the ksh version automatically
• sync the use of non-ASCII characters over files (unification)
fix the regression test’s results while here, which have been
broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
bian; track down commits in all files of oksh-mirbsd and mksh
to get correct copyright years per-file, as is BSD custom
similarily simple one from scratch, which however performs
better than espie's with AFREE_DEBUG enabled which took away
the benefit of the double-linked-list approach
all of (core) mksh is now MirOS licenced
compile all source files at once using -fwhole-program --combine,
similarily to how it used to be done in older mksh versions, except
that the flags are now hardcoded; tested with llvm-gcc4.2 from MirPorts
because categories in check.t are OR’d:
• no-stderr-ed disables the newish-ed tests (tried using testcase)
• stdout-ed enables the oldish-ed tests (variable, if the above
testcase succeeds, it’s added, but QNX overrides the variable)

12:52⎜«replaced:#!/bin/mksh» the problem was
12:52⎜«replaced:#!/bin/mksh» it creates src when you give hime src.c
12:53⎜«replaced:#!/bin/mksh» and it confused your Build.sh
12:54⎜<mirabilos:#!/bin/mksh> which compiler does it use?

• split up regression test to force this behaviour
• remove the gunk from our MirBSD™ startup scripts again
• mention arc4random.c changes on website, sync clog, warn packagers
didn’t tell me which one (T H A N K S !)… since I have no FleaBSD shell
account, I tried on DragonFly and MidnightBSD, which both are content
when adding <sys/types.h> first… let’s hope this fixes all 386BSD derivates
removes the \n part of a “\\\n” sequence, but not the backslash ⇒ we can’t

someone might want to add this to *(autoconf) Portable Shell::

• distrib/special/mksh/Makefile: sync check categories, this was missed
• mksh.hts: sync clog
In this case: reset the locale to “C” at start.
Otherwise, perl/OpenBSD fails in an UTF-8 environment, just
because OpenBSD 4.3/zaurus still has no locales in 2008.
change – this might affect other OSes too in time for R34
• one of the regression tests had an unexpected failure if running as root
• www: sync clog; log newer mksh built on newer OpenBSD works fine

00:51⎜<replaced_> it needs -A

00:52⎜<replaced_> -A Translates on a byte-by-byte basis. When this flag
00:52⎜<replaced_> is specified tr does not support extended

⎜ ______________________________________________________________
00:53⎜<replaced_> this works of course
• more int → bool
• more regression tests: check if the utf8-hack flag is really disabled
at non-interactive startup, enabled at interactive startup, if the
current locale is a UTF-8 one
• make the mksh-local multibyte handling functions globally accessible,
change their names, syntax and semantics a little (XXX more work needed)
• optimise
• utf_wctomb: src → dst, as we’re writing to that char array (pasto?)
• edit.c:x_e_getmbc(): if the second byte of a 2- or 3-byte multibyte
sequence is invalid utf-8, ungetc it (not possible for the 3rd byte yet)
• edit.c:x_zotc3(): easier (and faster) handling of UTF-8
• implement, document and test for base-1 numbers: they just get the
ASCII (8-bit) or Unicode (UTF-8) value of the octet(s) after the ‘1#’,
or do the same as print \x## or \u#### (depending on the utf8-hack flag),
plus support the PUA assignment of EF80‥EFFF for the MirBSD encoding “hack”
(print doesn’t, as it has \x## and \u#### to distinguish, but we cannot use
base-0 numbers which I had planned to use for raw octets first, as they are
used internally): http://thread.gmane.org/gmane.os.miros.general/7938
• as an application example, add a hexdumper to the regression tests ☺
• apply diff from mirbsdksh-1.11:
#ifdef DUP2_BROKEN
/* Ultrix systems like to preserve the close-on-exec flag */
‣ XXX we do #ifdef __ultrix here (imake-style) instead of mirtoconfing it
(but does anyone know of any other OS with the same problem? plus we’d
see it as we now know the symptoms)
• remove ultrix Build.hs warn=' but might work…' in the hope it DOES
• detecting a lot more compilers (stolen from CMake, admittedly, as they
were the first coming up at G**gle with usable #ifdefs)
• handling MIPSpro
• more system info on IRIX
‣ I/O redirection seems broken:
$ (date; date >/dev/null; date) | wc -l
1 (expected: 2)
‣ other than that: working fine
‣ -YBSD (default) and -YSYSTEM_FIVE don’t work, just -YPOSIX, somehow
• Fix $(…) to `…` for OSF/1 V2.0 /bin/sh
‣ this compiler is FUBAR though:
$ cat >t.c

$ cc t.c
ld:

$ echo $?
0
$ ls -l a.out
-rwxr-xr-x 1 mirbsd users 10835 Jul 21 17:12 a.out
‣ it seems to have ucode, but man is not installed
• new mirtoconf check: mkstemp(3)
• if !HAVE_MKSTEMP (Ultrix), use tempnam(3)
• only use printf(1) if it exists (it doesn’t on Ultrix)
• a few more signals
• add S_ISLNK if the OS doesn’t define it
• add strcasecmp(3) proto for Ultrix (it _is_ in <portability.h>, but
only for -YBSD I think)
• fgrep(1) on Ultrix doesn’t do “-e ① -e ②”
10x DEChengst:#UnixNL for giving access
it can’t do -Werror, that’s why it mis-detects attribute support.
