command; setting one still unsets the other at first)
• Change subst_exstat to be conformant unless -o sh is set and -o posix isn’t
• In lksh, make subst_exstat (newly) conformant if -o posix
• New MKSH_BINSHPOSIX to accompany MKSH_BINSHREDUCED
• Sync lksh manpage precisely
• 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
until R40 is definitively out (so there MAY still be an R39d)
this commit can easily be reverted in its entirety later, when
Build.sh’s compatibility for “-combine” &c. is removed too
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!
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
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
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)
• shell flags are now handled in one single place (sh_flags.h)
• sync comments (between enum and array) and manpage with reality
• FMONITOR is now no longer needed for Hartz IV shells
