From 973890e2c913c466b3dfb48c8bd01c28a7baf6c5 Mon Sep 17 00:00:00 2001 From: Lance Stout Date: Thu, 28 Oct 2010 10:42:23 -0400 Subject: Added try/except for setting signal handlers. Setting signal handlers from inside a thread is not supported in Python, but some applications need to run Sleek from a child thread. SleekXMPP applications that run inside a child thread will NOT be able to detect SIGHUP or SIGTERM events. Those must be caught and managed by the main program. --- sleekxmpp/xmlstream/xmlstream.py | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) diff --git a/sleekxmpp/xmlstream/xmlstream.py b/sleekxmpp/xmlstream/xmlstream.py index 630e68bf..cc192715 100644 --- a/sleekxmpp/xmlstream/xmlstream.py +++ b/sleekxmpp/xmlstream/xmlstream.py @@ -199,11 +199,15 @@ class XMLStream(object): self.auto_reconnect = True self.is_client = False - if hasattr(signal, 'SIGHUP'): - signal.signal(signal.SIGHUP, self._handle_kill) - if hasattr(signal, 'SIGTERM'): - # Used in Windows - signal.signal(signal.SIGTERM, self._handle_kill) + try: + if hasattr(signal, 'SIGHUP'): + signal.signal(signal.SIGHUP, self._handle_kill) + if hasattr(signal, 'SIGTERM'): + # Used in Windows + signal.signal(signal.SIGTERM, self._handle_kill) + except: + logging.debug("Can not set interrupt signal handlers.
