tg eb9050b8f8 stop using issetugid(2) for ±p check as it’s probably not the right tool 2015-10-05 17:59:00 +00:00
tg 4adcfe8b58 oksh sync, simplify *all* if(x)free(x); constructs, simplify x_push() and sync boilerplate while here 2015-09-05 19:19:12 +00:00
tg edf76ec8e6 harden the crlf vs lf tests even more; use binary mode explicitly on OS/2 2015-07-09 20:52:43 +00:00
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 1351c5eb0f permit building lksh with printf builtin, for testing 2015-03-20 23:37:17 +00:00
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 26f15bd938 permit $1, $!, etc. to be nameref’d again ($_ was); spotted by Jb_boin, 10x! 2014-09-03 19:22:51 +00:00
tg d2ef1d5d2c bump 2014-06-24 20:47:47 +00:00
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
2014-06-09 13:25:53 +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 ;)

tg 89e774fd7e • fix ${12345678901234567890} segfault (OOB access / integer overflow)
‣ 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

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)
• “set -x” manually (cmdline too) snapshots fd#2 now
• “set -o inherit-xtrace” introduced; default still enabled
• reverted iodup printing to pre-R45 behaviour
• made Flag(FXTRACE) a proper state machine

tg dc94c3d205 after enough complaints by POSIX sh advocates,
• make parsing numbers with leading digit-zero as octal independent of
  mksh/lksh and dependent on set -o posix; adjust manpages to match
• warn about these changes and why mksh uses 32-bit consistent arithmetics
  and point people to lksh for host-long undefined-behaviour arithmetics
• point out, explicitly, that it is *legal* for the operating environment
  to make 'print $((2147483647 + 1))' (on a 32-bit system; adjust for a
  64-bit system) to run 'rm -rf ~ /' instead

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
