Summary: During shutdown, the overlay background thread is terminated, and the overlay closed, but EdenServer timers are still running. One of which being the manageOverlay one which performs a maintenance on the Overlay. In some cases, shutdown and this timer are racing each other, causing the timer to run after the overlay has been closed, causing a use after free and crashing EdenFS. To solve this, we can either add locks around closing the overlay and the maintenance to guarantee that they do not race, or we can move the maintenance operation to a thread that is known to be running only when the overlay is opened. This diff takes the second approach. The bug manifest itself like so: I0712 01:16:48.253296 21620 EdenServiceHandler.cpp:3394] [000002517432E1E0] initiateShutdown() took 368 µs I0712 01:16:48.253838 24700 PrjfsChannel.cpp:1185] Stopping PrjfsChannel for: C:\\cygwin\\tmp\\eden_test.stop_at_ea.m3931hyz\\mounts\\main I0712 01:16:48.258533 19188 EdenServer.cpp:1624] mount point "C:\\cygwin\\tmp\\eden_test.stop_at_ea.m3931hyz\\mounts\\main" stopped V0712 01:16:48.258814 19188 EdenMount.cpp:851] beginning shutdown for EdenMount C:\\cygwin\\tmp\\eden_test.stop_at_ea.m3931hyz\\mounts\\main V0712 01:16:48.259895 19188 EdenMount.cpp:855] shutdown complete for EdenMount C:\\cygwin\\tmp\\eden_test.stop_at_ea.m3931hyz\\mounts\\main V0712 01:16:48.287378 19188 EdenMount.cpp:861] successfully closed overlay at C:\\cygwin\\tmp\\eden_test.stop_at_ea.m3931hyz\\mounts\\main Unhandled win32 exception code=0xC0000005.

Summary: It turns out that initializing objc types before (disabling appnap) and after (via libcurl [2]) fork() would abort the program like: objc[<pid>]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. It seems objc really dislikes fork. Disabling the objc logic before fork seems to be the only way to unblock the issue. Other approaches considered: - Avoid `fork()`: not really fesiable for performance (startup, Python GIL) reasons. - Ensure chgserver does not create threads (see https://bugs.python.org/issue33725). Not possible since appnope implicitly creates a (short-lived?) thread. - Disable AppNap without using objc: does not seem trivial. - Set `OBJC_DISABLE_INITIALIZE_FORK_SAFETY` to `YES`. Abort with a different message [1]. [1]: ``` The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec(). Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug. ``` [2]: ``` (lldb) bt * thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1 * frame #0: 0x00007ff81395f067 libobjc.A.dylib`objc_initializeAfterForkError frame #1: 0x00007ff81395f187 libobjc.A.dylib`performForkChildInitialize(objc_class*, objc_class*) + 274 frame #2: 0x00007ff81394a479 libobjc.A.dylib`initializeNonMetaClass + 617 frame #3: 0x00007ff813949f12 libobjc.A.dylib`initializeAndMaybeRelock(objc_class*, objc_object*, mutex_tt<false>&, bool) + 232 frame #4: 0x00007ff813949c93 libobjc.A.dylib`lookUpImpOrForward + 1087 frame #5: 0x00007ff81394e02f libobjc.A.dylib`object_getMethodImplementation + 153 frame #6: 0x00007ff813b12934 CoreFoundation`_NSIsNSString + 55 frame #7: 0x00007ff813b128dc CoreFoundation`-[NSTaggedPointerString isEqual:] + 36 frame #8: 0x00007ff813b05609 CoreFoundation`CFEqual + 533 frame #9: 0x00007ff813b0b2a3 CoreFoundation`_CFBundleCopyBundleURLForExecutableURL + 220 frame #10: 0x00007ff813b069cb CoreFoundation`CFBundleGetMainBundle + 116 frame #11: 0x00007ff813b28ade CoreFoundation`_CFPrefsGetCacheStringForBundleID + 71 frame #12: 0x00007ff813b2f52f CoreFoundation`-[CFPrefsPlistSource setDomainIdentifier:] + 92 frame #13: 0x00007ff813b2f46c CoreFoundation`-[CFPrefsPlistSource initWithDomain:user:byHost:containerPath:containingPreferences:] + 99 frame #14: 0x00007ff813b2f351 CoreFoundation`__85-[_CFXPreferences(PlistSourceAdditions) withManagedSourceForIdentifier:user:perform:]_block_invoke + 156 frame #15: 0x00007ff813c622a7 CoreFoundation`-[_CFXPreferences withSources:] + 60 frame #16: 0x00007ff813cac80f CoreFoundation`-[_CFXPreferences withManagedSourceForIdentifier:user:perform:] + 240 frame #17: 0x00007ff813b2a1ab CoreFoundation`-[CFPrefsSearchListSource addManagedSourceForIdentifier:user:] + 98 frame #18: 0x00007ff813c83a18 CoreFoundation`__108-[_CFXPreferences(SearchListAdditions) withSearchListForIdentifier:container:cloudConfigurationURL:perform:]_block_invoke.160 + 287 frame #19: 0x00007ff813c836e8 CoreFoundation`-[_CFXPreferences withSearchLists:] + 60 frame #20: 0x00007ff813b29f50 CoreFoundation`__108-[_CFXPreferences(SearchListAdditions) withSearchListForIdentifier:container:cloudConfigurationURL:perform:]_block_invoke + 279 frame #21: 0x00007ff813c83879 CoreFoundation`-[_CFXPreferences withSearchListForIdentifier:container:cloudConfigurationURL:perform:] + 374 frame #22: 0x00007ff813b29a42 CoreFoundation`-[_CFXPreferences copyAppValueForKey:identifier:container:configurationURL:] + 137 frame #23: 0x00007ff813b29978 CoreFoundation`_CFPreferencesCopyAppValueWithContainerAndConfiguration + 101 frame #24: 0x00007ff8145c672b SystemConfiguration`SCDynamicStoreCopyProxiesWithOptions + 155 frame #25: 0x000000010272a315 hg`Curl_resolv(data=0x00007f8dea888a00, hostname="api.github.com", port=443, allowDOH=true, entry=0x000000030a12be10) at hostip.c:675:30 [opt] frame #26: 0x000000010272a68c hg`Curl_resolv_timeout(data=<unavailable>, hostname=<unavailable>, port=<unavailable>, entry=<unavailable>, timeoutms=<unavailable>) at hostip.c:908:8 [opt] [artificial] frame #27: 0x0000000102753e1e hg`create_conn at url.c:3440:12 [opt] frame #28: 0x0000000102753cfe hg`create_conn(data=0x00007f8dea888a00, in_connect=0x000000030a12bed8, async=0x000000030a12bf8f) at url.c:4077:12 [opt] frame #29: 0x000000010275026b hg`Curl_connect(data=0x00007f8dea888a00, asyncp=0x000000030a12bf8f, protocol_done=0x000000030a12bfb2) at url.c:4156:12 [opt] frame #30: 0x000000010273dbd1 hg`multi_runsingle(multi=<unavailable>, nowp=0x000000030a12c020, data=0x00007f8dea888a00) at multi.c:1858:16 [opt] frame #31: 0x000000010273d6ae hg`curl_multi_perform(multi=0x00007f8deb0699c0, running_handles=0x000000030a12c074) at multi.c:2636:14 [opt] frame #32: 0x0000000102726ada hg`curl_easy_perform at easy.c:599:15 [opt] frame #33: 0x0000000102726aa8 hg`curl_easy_perform [inlined] easy_perform(data=0x00007f8dea888a00, events=false) at easy.c:689:42 [opt] frame #34: 0x00000001027269a4 hg`curl_easy_perform(data=0x00007f8dea888a00) at easy.c:708:10 [opt] frame #35: 0x00000001025e1cf6 hg`http_client::request::Request::send::h13a4e600f6bc5508 [inlined] curl::easy::handler::Easy2$LT$H$GT$::perform::h2ba0ae1da25a8852(self=<unavailable>) at handler.rs:3163:37 [opt] ``` Reviewed By: bolinfest Differential Revision: D40538471 fbshipit-source-id: cd8611c8082fbe2d610efb78cb84defdb16d7980
