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.
• 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 *
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
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
• 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.
• 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
• 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
