User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; zh-CN; rv:1.9.1.8) Gecko/20100202 Firefox/3.5.8 Build Identifier: 3.6 I met some crashes in my embedded xulrunner application on mac. This is the trace: Thread 75 Crashed: 0 libnspr4.dylib 0x39f0c45f poll + 655 1 libnspr4.dylib 0x39f083b9 PR_Poll + 121 2 XUL 0x3a2fd04b nsSocketTransportService::Poll(int, unsigned int*) + 123 3 XUL 0x3a2fd5fb nsSocketTransportService::DoPollIteration(int) + 459 4 XUL 0x3a2fd913 nsSocketTransportService::OnProcessNextEvent(nsIThreadInternal*, int, unsigned int) + 51 5 XUL 0x3ac55b9c nsThread::ProcessNextEvent(int, int*) + 124 6 XUL 0x3ac178d7 NS_ProcessPendingEvents_P(nsIThread*, unsigned int) + 71 7 XUL 0x3a2fde9e nsSocketTransportService::Run() + 190 8 XUL 0x3ac55bfa nsThread::ProcessNextEvent(int, int*) + 218 9 XUL 0x3ac17803 NS_ProcessNextEvent_P(nsIThread*, int) + 35 10 XUL 0x3ac55d8c nsThread::ThreadFunc(void*) + 140 11 libnspr4.dylib 0x39f09cb8 _pt_root + 152 12 libSystem.B.dylib 0x96e33fbd _pthread_start + 345 13 libSystem.B.dylib 0x96e33e42 thread_start + 34 I also saw some crash reports in mozilla with the same crash stack: (see http://crash-stats.mozilla.com/report/list?platform=mac&query_search=signature&query_type=exact&query=poll&date=&range_value=2&range_unit=weeks&process_type=all&plugin_field=&plugin_query_type=&plugin_query=&do_query=1&signature=poll) most of them crashed in FD_SET or FD_ISSET calls in poll method. I guess the default size FD_SETSIZE (currently 1024) is not enough on Mac OS. I saw some code in ptio.c which defines bigger FD_SETSIZE, can we do the simlar thing for Mac platform? #if defined(_PR_POLL_WITH_SELECT) #if !(defined(HPUX) && defined(_USE_BIG_FDS)) /* set fd limit for select(), before including system header files */ #define FD_SETSIZE (16 * 1024) #endif #endif Reproducible: Always
Mass change of bugs in the Embedding: Mac component in preparation for archiving it. I don't believe any of these are useful any more, as we don't have a mac embedding API. If they are relevant, they should be moved to an alternate component.
