tg 7f16464902 slightly optimised and, more importantly, much more consistent (use only
one set of CTRL, UNCTRL, and new ISCTRL macros) C0 and DEL handling; the
optimisation only works for 7-bit ASCII, so those places 8-bit must pass
intact have an added check

also, while here, remove an editor oops (‘;’), oksh rcsid sync (they did
accept I was right wrt. set -e), int → bool, and code merge/cleanup

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 5eb6995d75 Ypnose discovered a problem with multi-line prompts and SIGWINCH
related to caching some values (downside, pprompt gets back doprint option)

tg bf94b7e2ec fun: when writing this code I feared an off-by-one;
Steffen Daode Nurpmeso stumbled upon it and gave very detailed
instructions on how to reproduce it (thanks!); fix that

also only call x_bs0 if xcp < xep because *xep is undefined

tg 247e20c524 • Completely overhaul prompt length calculation and
prompt display routines; make Emacs and Vi share
  code, permitting reducing of duplication and code
  removal as well as more consistent behaviour; put
  some common code into shared helper functions, too
• New x_adjust() logic (Emacs mode): when determining
  what portion of a line to render use a much more
  sophisticated algorithm and try to fill up ⅔ of the
  total screen width (with line and prompt both) also
  as wished from Steffen Daode Nurpmeso
2013-07-26 20:33:39 +00:00
tg 3876b38220 Steffen Daode Nurpmeso found an actual bug:
Whenever the SIGEXIT trap was set (to anything, really)
syntax errors and interruptions were not ignored any more
in an interactive shell (where they should be, unless
set -e is used); fix that.

tbd: traps should probably only be marked as pending
and run for LLEAVE/E_NONE

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 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 7cce9de0bc one can’t cast an unsigned int to a signed int portably either, if the value
is larger than the positive range of the latter (implementation-defined), so
avoid them in all explicit cases and rearrange stuff and check for it

(I’m gonna have to revise lots more code…)
