fc27886680 when ^C’ing out of an interactive shell, also throw away the here documents (probably leaks, maybe not due to quitenv, but not much) 2012-10-30 20:07:00 +00:00

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]

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.

9fbdef8e60 pure RCSID sync with OpenBSD, as we introduced SIGWINCH tracking earlier 
XXX we could track whether tty_fd has already been successfully opened,
XXX the ttystate initialised, and then just never close it unless it is
XXX necessary, then we can keep COLUMNS/LINES accurate in scripts, even

eac85ffdf1 OpenBSD found out that "building argv for $* and $@" manipulates l->argv

the original parts from argv[] there without touching argv passed to main

ea01d80833 hackish work-around the lexer to make alias definitions in mksh -c 
work (Closes: #517009) and mention in the manpage why they sometimes

95a2c63096 • implement fcntl(2)-based advisory locking as an alternative iff flock(2) 
is not found, from a suggestion by RT (LP: #912691)
• try harder (in a loop) to acquire a file lock if the locking mechanism
  documents EINTR is a possibility (fcntl always, flock on Linux not .Ox)
• use -std=c99 not -std=gnu99 if it must be at all

24e8a6996b always keep x_cols and x_lins valid; check once at start including tty init 
if we find any, but not later; do not check on every read

⇒ allows changing COLUMNS and LINES (independent of each other, or both)
  for script shells by passing them in an environment setting, even if
  we get a tty; interactive shells still check before each line is read…

reported by the PLD guys, thanks
