tg 2e7509548a integrate latest changes from oksh: Wed Sep 4 15:49:19 2013 UTC by millert
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.

tg fda010d8de SECURITY: Unbreak “set +p”, broken by OpenBSD ksh change.
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.

tg ead77623d3 Fix most “set -x” problems (LP#1179287)

• reverted iodup printing to pre-R45 behaviour
• made Flag(FXTRACE) a proper state machine

tg 6aa08008b3 replace warnings for sig_t detection 2013-06-03 22:27:15 +00:00
tg 8256f266ff fix a number of warnings and other issues:
• 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

tg f0f34eb7b6 • Allow setting both -o posix and -o sh (although only in the same
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

tg deb4a3bf20 Oh well… this looks well, is done done, and gcc-snapshot doesn’t complain:
• 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

tg 74e2ef8b0b one more int → bool; mention “set -o sh” may (on raare OSes) be enabled

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?)
