‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
‣ always use our wcwidth code
‣ only use our strlcpy code if none found
• fix a couple of gcc-snapshot and clang/scan-build warnings
• mksh R49~rc1
Add a proper suspend builtin that saves/restores the tty and pgrp
as needed instead of an alias that just sends SIGSTOP. Login shells
may be suspended if they are not running in an orphan process group.
TODO: I am seriously considering following Chet and changing
the way this works, by explicitly dropping privs unless the
shell is run with -p. Every other shell does it like mksh,
except Heirloom sh, which on the other hand doesn’t know any
explicit set -p or set +p (though it doesn’t know set +foo
for any foo either).
┌──┤ QUESTION: Do we need the ability to do this:
│ tg@blau:~ $ ./suidmksh -p -c 'whoami; set +p; whoami'
│ root
│ tg
If not, I’m seriously considering to drop set ±p as well,
only parse -p on the command line, with +p being the default,
and dropping FPRIVILEGED.
Thanks to RT for noticing and jilles for initial follow-up
discussion, as well as Chet Ramey for doing the sane/secure
thing instead of following Debian.
• sig_t detection was a bit insane, it is a function-pointer type after all
• fix uninitialised variable in c_select which led to mistakenly accepting
invalid (nōn-numeric) input and acting, randomly, upon it
• keep SIGCHLD blocked in child after forking longer, for job list manip
• block SIGCHLD ifdef DEBUG_LEAKS to not run job foo during/after afreeall
• fix annoying ISO C90 vs. C99 (un)signed constant warning
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
• 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
AT&T SVR4 broke 'cc -c -o foo.o foo.c' totally
switch to an alternative method of finding out the prototypes
provided in IRC by dalias (thanks); RT says this fixes his
issues on SVR4 – let’s just ignore the ominous message from
cid 1004713D70A5362BACF about needing to be a compile-time
check unless something else pops up, I can’t think of something
that isn’t already covered
03:00⎜«RT|AO:#!/bin/mksh» cc -c -o a.out does not output a.out but conftest.o (!!)
evil… just use tcfn=conftest.o for now, cf. cid 1004713D70A5362BACF (but why must it be one?)
