Jilles Tjoelker <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #7 from Jilles Tjoelker <[email protected]> --- There is a proposal for an async-signal safe version of fork() called _Fork(), which does not call atfork handlers, at http://austingroupbugs.net/view.php?id=62 . This would help if the only problem with calling fork() is that it executes atfork handlers. It still executes a fair bit of code, but no user code. To make _Fork() async-signal safe, the malloc handling would have to be disabled as well, making malloc/free in the child more unsafe (but also interfering less with other threads in the parent). The handling of the lock for sem_open() and sem_close() uses pthread_atfork() and would be disabled as well. This may be useful for this and other situations that want to fork from signal handlers or other strange thread states. I have not found common implementations of _Fork(), though. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
