Charles-François Natali <neolo...@free.fr> added the comment: It's a little bit more complicated than that: - signals and threads don't mix well together - this will make syscalls fail with EINTR - the old SIGALRM handler is lost - etc
In short, don't use signals. I'm not sure there's a reliable way to write such a general-purpose wrapper (usually one can use select() with a timeout or spawn a subprocess and use communicate's timeout to achieve this kind of things). In your use case (issue #12157), I think that letting the test block is fine, since: - there's no easy way to add a timeout (but you could spawn a new interpreter and use communicate with a timeout if you really wanted to) - it will be caught by the faulthandler module - a test killed by faulthandler's timeout is more interesting to fix that a "common" failed test ;-) ---------- nosy: +neologix _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12410> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
