And another success today. Thanks to Michael DeHaan who suggested this could be threads problem I've wrote and testes this patch: http://github.com/kadamski/func/commit/241a9abb49ecc920c82703e61f77ecdda4b19911 diff --git a/func/minion/AuthedXMLRPCServer.py b/func/minion/AuthedXMLRPCServer.py index 0ec9ce0..7bba160 100644 --- a/func/minion/AuthedXMLRPCServer.py +++ b/func/minion/AuthedXMLRPCServer.py @@ -50,7 +50,7 @@ class AuthedSimpleXMLRPCRequestHandler(SimpleXMLRPCServer.SimpleXMLRPCRequestHan print "Error (%s): socket error - '%s'" % (self.client_address, e) -class BaseAuthedXMLRPCServer(SocketServer.ThreadingMixIn): +class BaseAuthedXMLRPCServer(SocketServer.ForkingMixIn): def __init__(self, address, authinfo_callback=None): self.allow_reuse_address = 1 self.logRequests = 1 This oneliner changes AuthedXMLRPCServer to use fork instead of threads. It seams that logging python module is just not thread safe. It also seams that PyOpenSSL is leaking memory when used with threads since now i can't see memory leaks in funcd. Adrian Likins found information that there is a patch fixing this in new version but we want Func working correctly on older systems and forking shouldn't be big performance problem so i believe it should be good idea to make this change. _______________________________________________ Func-list mailing list Func-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/func-list
