tg f463d9da76 • revert the cat hack for realpath and rename
‣ I was convinced by several that more magic is never the solution
• fix a comment: function cat already had precedence
• change cat loader to look for existence, FPATH included, before
  ditching the builtin; note that in manpage

tg a9e1101145 sync with actual z/OS <signal.h> contents 2015-05-01 16:08:26 +00:00
tg 93ccb42114 overhaul the signal handling:
• support NSIG_MAX from http://austingroupbugs.net/view.php?id=741
  and make a TODO for later to use sysconf(_SC_NSIG) at runtime
• bounds-check signals (e.g. no smaller than 1, but smaller than NSIG)
• align trap errorlevel with other shells
• make trap match what’s in POSIX and fixup the manpage
• refactor some code related to signals
• hide from kill builtin both EXIT and ERR pseudo-signals

tg 65f9b93926 ordinarily, lineno must be mksh_uari_t, but edit.c most of all isn’t ready,
so we mitigate a bit (in var.c mostly) and tweak another type already, and
add some checks (mksh_{,u}ari_t must fit into {,unsigned }long) and print
line numbers with %lu already

tg cad9bc86d3 Implement the “FKSH functions have local scope for shell options” feature
for mksh but not lksh; bump to R51-alpha.

While here, tweak build scripts a bit, fixup MirBSD-specific Makefile
things, remove part of a comment that’s uninteresting.

tg 2f52b993a1 • Build.sh: fix NSIG detection for gcc-snapshot
• all: bump version to R50-current; add more comments; whitespace
• all: remove all mkssert(); we’ll do full re-runs of scan-build and,
  hopefully, Coverity Scan/Prevent
• check.t: fix a testcase (sed could exit false, but we don’t care)
• eval.c: fix tilde_ok data type (only unsigned may shl constantly)
• exec.c: fix shebang buf array accesses to always go via uint8_t *

tg 7330970bfa fix some of the signal stuff (still didn’t get rid of awk(1) and printf(1)
calls in Build.sh, we need HOSTCC for that… which we should do, using BER
or something encoded for integers, and pregenerated hashtables as planned)

also, bump to R50 beta, due to today’s language changes

tg 495b798893 improved OE reporting for newer Darwin/OSX, by Ryan Schmidt <ryandesign@macports.org> 2014-05-27 13:41:53 +00:00
tg 033e1f4b9e fix LP#1277691 (“nameref RHS not syntax checked”) and the inability to
use errorf() while nameref states were being changed (by almost completely
eliminating the global variable) and the readonly first array variable
bypass (typo/refactoro); also, whitespace, one int → bool, and add a
comment wrt. the parser rewrite talked about with igli during a fever ;)

‣ not like oksh did, but using mksh’s built-in features

• mksh R49~rc1

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 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
