[ http://issues.apache.org/jira/browse/TUSCANY-959?page=comments#action_12458823 ] Geoff Winn commented on TUSCANY-959: ------------------------------------
Item 4 is harder than I first thought. On Linux we can ensure that the initialisation routine is called exactly once by using pthread_once. However, Windows has no direct equivalent to that and we have to use the dllmain functionality instead to ensure that the xmlInitParser is called exactly once and before any thread uses SDO. I'm looking into this at the moment. We cannot use static initialisation because in general there is no way to know when such a variable will be initialised. For example, it is possible the initialisation will be attempted on a thread that then gets pre-empted by a second, and that thread executes a libxml2 operation before the initialisation has completed. I'll update this JIRA when I have more information. > Please use thread-safe libraries > -------------------------------- > > Key: TUSCANY-959 > URL: http://issues.apache.org/jira/browse/TUSCANY-959 > Project: Tuscany > Issue Type: Improvement > Components: C++ SDO > Affects Versions: Cpp-current > Reporter: Caroline Maynard > Priority: Minor > Attachments: SAX2Parser.959 > > > One of our SDO for PHP users is planning to run in a multi-threaded web > server. > They have run an evaluation tool and only found one thread-safety issue - the > use of localtime() rather than localtime_r() in commonj/sdo/SDODate.cpp. > Please would you modify this call accordingly?
