• correct order of built-in commands; use POSIX special versus “all others”
plus “keeps assignments” as distinction, no longer play POSIX regular vs.
others game; sync manpage
• fix LP#1156707: map (( internally to “let]” which is no valid function
name and so can’t be overridden but is unlikely to be used otherwhere
and not strictly permitted (by POSIX) anyway
• we do not need -Wno-overflow any more, either
• bump to R45
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
00:45 -!- variable [root@freebsd/developer/variable] has joined #!/bin/mksh
• +b *!*root@*, +b $a:root, +b $r:root on one more channel
• certain checks to prevent:
00:47 < variable> wjcw: sh.h:308: error: conflicting types for 'getrusage'
01:19 < variable> oh
01:19 < variable> I needed to run Build.sh
• 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
– 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
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
was hard to type and hard to fix, galloc is also hard to fix, and some
things I learned will probably improve things more but make me use the
original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here
