--- Comment #3 from John Baldwin <[email protected]> --- This is a known longstanding issue with ptrace() and not trivially fixable. (It's also documented in truss's manpage I think, or perhaps only in gcore's manpage.) I have been trying to work on a possible solution for several months, but it won't be ready any time soon. (In particular, the issue is that ptrace() doesn't pass the signal to the debugger which then discards it until after it has awakened the sleeping thread and forced it out to the user/kernel boundary. The fix I'm working on aims to keep the thread asleep while letting the debugger intercept the signal and only interrupting the thread if the debugger passes the signal. The current WIP can be found here, but it's not really tested at all yet and I think it still panics when trying to use ptrace(): https://github.com/freebsd/freebsd/compare/master...bsdjhb:spurious_EINTR ) -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
