Bruce Evans 3ef22d496d Backed out previous backout. Put y.tab.h back in SRCS. 1998-05-06 15:33:59 +00:00
Bruce Evans e43e36af7d Backed out previous commit. It was tested, but not for the case where
a separate object tree doesn't exist.  Crufty makefiles will have to
put y.tab.h in SRCS so that we know not to create foo.h from foo.y.

Martin Cracauer 8624242ab8 Back out my previous attempt to fix SIGINT/SIGTERM behaviour 1998-02-06 23:50:39 +00:00
Martin Cracauer 9dee16dba6 Fix handling of SIGINT/SIGQUIT for foreground subprocesses. Most
urgent need is when you run sh around a program that intentionally
uses SIGQUIT/SIGINT for asynchronous events, i.e. $EDITOR started from
system(2), like many mailers do. This fixes PR bin/1206 and possibly
bin/4241.

The solution committed has been tested for a large number of possible
cases (see recent discussion on cvs-committers). I completed a make
world, made sure 'make world' is interruptable and used the changed
/bin/sh as a login shell all day, including job control and using
SIGQUIT-catching programs (to write this message :-).

1997-11-12 04:32:50 +00:00
Bruce Evans 28701136f7 Fixed some type and value mismatches. setsignal() returned a bogusly
cast value that was always ignored.  Rev.1.9 of trap.c made this
more bogus by returning a semantically different value after calling
siginterrupt().  Avoid these problems by not returning a value.

Andrey A. Chernov 8dd81503df 1) Fix longstanding bug:
trap 'echo xxx' 1 2 3 15
	read x
is not interrupted by ^C (due to restartable read syscall) and must be
interrupted per POSIX
Worse case:
	read -t 5 x
hangs forever after ^C pressed (supposed to timeout after 5 secs)
Fixed by adding siginterrupt(signo, 1) after catch handler installed

2) Do not reinstall sighandler immediately after it is called,
BSD do it for us

Mike Smith afa53c8df7 Add the '-t timeout' option to the 'read' builtin. This allows the
'read' command to return an error if the user fails to supply any
input withink a given time period.  The behaviour of this option is
similar to that of the like-named option in ksh93.
