tg b868c517b7 remove *all* nonnull assertions and other workarounds for clang scan-build 
this beast evolved in the last 2½ years, and we’ve had trouble with
some of them earlier
 2012-12-01 01:36:30 +00:00
tg f6728353bd fix “null argument where non-null required” warning 2012-11-30 22:17:32 +00:00

tg 0f3071a8b2 MKSH_DISABLE_EXPERIMENTAL is a NOP again; use ${ precmd;} in dot.mkshrc 2012-11-30 20:19:16 +00:00
tg f63bcae02c … oh well, but MidnightBSD gcc picks on "" too, so just stick to NULL, it’s cheapest 2012-11-30 19:58:48 +00:00
tg 0f46c5e321 so’s clang… 2012-11-30 19:57:35 +00:00
tg 9a6ebef8ca The MidnightBSD/amd64 system compiler (Target: amd64-undermydesk-freebsd) 
gcc version 4.2.1 20070719  [MidnightBSD] has stricter -Wformat checking
 2012-11-30 19:51:25 +00:00
tg 77c4cb88e4 implement tty tracking and bump to R41 for feature completeness 
• tty_fd is now never closed
• new tty_hasstate tracks tty_state (cf. thread around
  http://article.gmane.org/gmane.os.miros.mksh/79 and PLD bug)
• as users requested, importing COLUMNS or LINES from the environment
  now removes its special-ness as does unsetting it
• otherwise, setting COLUMNS or LINES is honoured until the next SIGWINCH
  arrives or change_winsz is otherwise run (e.g. before displaying the
  prompt in the interactive command line editing modes)
• SIGWINCH is now honoured before each reading of $COLUMNS and $LINES too
• change the Uhr to match – it no longer calls stty(1) ☺

tg 730bc915bd tty_close() before exec() is not necessary, it’s FD_CLOEXEC anyway 
only tty_close() left are now after the early init in main, which
is new, and when not FTALKING…

tg b58d7b8053 fix regression wrt. pdksh (introduced between R40e and R40f) 
about how and when the display is redrawn by reverting one
bool back to an int, as it’s used as a counter (hm, should
be an unsigned I guess but…)

on the other hand, xlp_valid should’ve been a bool, make it so

tg c7419d9e6a defer setting exstat for eval to 0 (the one used in case shell() is empty) 
until after the stuff run in shell() has had a chance to toy with $?

bug forwarded by one of our packagers, found by one of their users
 2012-10-21 21:55:05 +00:00
tg 31f24a4040 add some bounds, for a subsequent commit: 
• all writers of exstat ensure the value is in [0; 0xFF]
• all readers of exstat AND it with 0xFF (not strictly needed thus)
• trap_exstat is “safe”, i.e. always either -1 or [0; 0xFF]

tg bebb2d2254 EXPERIMENTAL optimisation for “sh -c 'foo'” to equal “sh -c 'exit foo'” iff 
several conditions are met as outlined below; for more background, refer to
http://www.FreeBSD.org/cgi/query-pr.cgi?pr=113860

We don’t yet optimise 「% sh -c '{ echo a; sleep 10;}&'; sleep 1; ps T」 so
the FreeBSD® sh approach cannot work for us, but scanning the “sh -c” argu‐
ment for disallowed characters and, if not, setting a flag that enables the
shell to exec the tree when parsed as TCOM *and not c_trap()* was possible.

Disallowed characters are currently C_QUOTE except space, that is:
Tab Newline " # $ & ' ( ) * ; < = > ? [ \ ] ` |

This should catch all cases of magic, variables, subshells, pipelines, etc.

tg 1f43cc907d fix backslash-asterisk glob noise for nōn-existant targets and tilde
