This component starts a new thread with NS_NewThread(getter_AddRefs(workerThread),NULL); Afterwards I dispatch a runnable (also implemented in c++) to the new workerThread. what happens then is, if I try to create and use an object of an component (written in JS) within the run-function TB and FF freeze or crash with access violation. It doesn't always happen. I wrote a tiny extension that should demonstrate what I mean. You can download the source and the .xpi files for TB and FF under http://rapidshare.com/files/94272019/complete.zip.html If that can make any difference, the .xpi packages are build against TB CVS(23.02.08 08:00 GTM+1) and FF CVS(23.02.08 9:00 GTM+1) Reproducible: Always Steps to Reproduce: 1. Download packages from http://rapidshare.com/files/94272019/complete.zip.html 2. install extension 3. start TB or FF with the console and wait about 10 seconds 4. if it doesn't work the first time restart FF or TB Actual Results: TB and FF crashes with access violation Expected Results: There should be 99 new threads, but no access violation.

technically your js should include nsIClassInfo.flags & nsIClassInfo.THREADSAFE your stack traces are unfortunately useless as they lead into your code. please see http://developer.mozilla.org/en/docs/How_to_get_a_stacktrace_with_WinDbg which will enable you to get symbols for your firefox build and provide a stack trace. nsCOMPtr<nsIJackFWorker> jackFWorker = do_CreateInstance("@mozilla.org/nsJackFWorker;1", &rv); you need to error check CreateInstance jackFWorker->SetNumber(i); nsCOMPtr<nsIThread> workerThread; NS_NewThread(getter_AddRefs(workerThread),NULL); you need to error check NS_NewThread offhand, i'm not exactly sure what's keeping workerThread alive. the reference you have will go away when this function returns. nsCOMPtr<nsIJackFGraphicExtension> plugy = do_CreateInstance("@mozilla.org/jackfjackftemplate;1", &rv); you need to error check CI rv = plugy->AnalyseGraphic(score);

I tried to get the useful stack traces. I build TB and the example with debug enabled and started it with WinDbg Afterward I got: Assertion failure: cx->thread->id == js_CurrentThreadId(), at d:/mozilla/ mozilla_source/mozilla/js/src/jsapi.c:840 ###!!! ASSERTION: nsCacheSession not thread-safe: '_mOwningThread.GetThread() == PR_GetCurrentThread()', file d:/mozilla/mozilla_source/mozilla/netwerk/cache/sr c/nsCacheSession.cpp, line 48 <@Mossop> told me some days ago that maybe I get this assertion because the factory of the JS component gets registerd from the main thread. And if I call the factory from a worker thread their cx (whatever it is) is not the same. If he is right then does it mean you can't use a JS component from a non-mainthread? the stack trace is: 0:010> kp ChildEBP RetAddr 03bdf31c 002bed7a ntdll!DbgBreakPoint 03bdf48c 002bf03f xpcom_core!Break(char * aMsg = 0x03bdf4b0 "###!!!

Ok, I tried all you said. I used WinDbg. If I start TB with argument output w/ it crashes before it starts my example. I think the right commands are ~* kp Then search for the right thread and the right function where cx is used.

i said attach not paste :(. but yes, i can really read it (as it happens, I can read much less friendly stack traces too, but that flavor is quite friendly). WARNING: Frame IP not in any known module. Following frames may be wrong. 0012f4d8 00f0d052 0xb89990 is odd, you're missing a something. (you can try "lm" in windbg to see if you can figure out what that is, but don't paste it!) be on irc and ask someone to help you find timeless. anyway, ignoring that bookkeeping. it looks like threads 10..13 (~10, ~11, ~12, ~13) all tripped the same assertion. I think it basically means that the componentloader is no longer threadsafe. this is unfortunate and should be fairly easily fixed. I believe it's a regression, although I'm not certain, because while I have worked w/ threads, most of my threads didn't actively attack the componentmanager. Offhand, the simplest thing that the componentloader can do is recognize when the cached context it has is from some other thread, if it is, the component loader should just create a new context and use that for the call. JSContexts can safely be used. If you're looking for the quick and dirty approach, make the JSCLContextHelper create its own context each time it does this auto thing instead of using the one someone provides.

there's probably an xpconnect owned jscontext available per thread, i should try to find/use it. this patch creates one JSContext per module, which is fairly expensive given how rarely the context would be use. whereas we only need one context per thread.

I build everything again. The good thing is, it doesn’t terminate unfortunately it now seems to freeze. I had to break WinDbg manually. I can’t read the trace but my printf commands say, that it never returns from nsCOMPtr<nsIJackFGraphicExtension> plugy = do_CreateInstance("@mozilla.org/jackfjackftemplate;1", &rv); I put in some more error checking so pleas use the new example. The new trace is: http://pastebin.mozilla.org/346425 It is really long, I’ve got 99 worker threads. I think Thread number 10 is the first interesting one.

Hi, I have undone the last patch and applied the new one. If got the following build error. http://pastebin.mozilla.org/347697 If I understood it right, you always have to provide ~* kp for a useful stack? thanks christian
if you're hanging, it's nice to include the analyze output, but for now since output in a pastebin or attachments are free, yes, always add a ~* kp or similar. I think from reading as I wrote the previous patch that I basically left an unbalanced request open in a bad place so there wasn't another interesting thread.

no problem. I'll try whatever you post. It build but I've an other errors when I start tb. http://pastebin.mozilla.org/348089 ~* kp = http://pastebin.mozilla.org/348090 maybe the problem is somewhere here 0012fba8 00f33ebd xpc3250!mozJSComponentLoader::ModuleEntry::~ModuleEntry(void)+0x5d [d:\mozilla\mozilla_source\mozilla\js\src\xpconnect\loader\mozjscomponentloader.cpp @ 1558] cx at this poit is: 0:000> dt cx Local var @ 0x12fb9c Type JSCLContextHelper +0x000 mContext : (null) +0x004 mOptions : 0x1021e1d0 +0x008 mVersion : 0x12fbc8 (No matching name)
ok, that's going to take some debugging breakpoint JSCLContextHelper::JSCLContextHelper and find out why it doesn't set mContext. It'd also be good if you could compare similar code which tries to get a context to see what's different. I'll look on Sunday.
I have tried to find something useful. Maybe I'm worng but what I found is strange. You where right. JSCLContextHelper::JSCLContextHelper() : mContext(0) { nsCOMPtr<nsIThreadJSContextStack> jsContextStack = do_GetService("@mozilla.org/js/xpc/ContextStack;1"); if (!jsContextStack) return; ... } returns and jsContextStack == null first the stacks: ~*kp: http://pastebin.mozilla.org/348957 The calling of do_GetService("@mozilla.org/js/xpc/ContextStack;1"); ends in here with a strange problem NS_IMETHODIMP nsComponentManagerImpl::GetServiceByContractID(const char* aContractID, const nsIID& aIID, void* *result) { // test this first, since there's no point in returning a service during // shutdown -- whether it's available or not would depend on the order it // occurs in the list if (gXPCOMShuttingDown) { // When processing shutdown, don't process new GetService() requests #ifdef SHOW_DENIED_ON_SHUTDOWN nsXPIDLCString iid; iid.Adopt(aIID.ToString()); fprintf(stderr, "Getting service on shutdown.

I tried something else. Straight before gXPCOMShuttingDown == ture I get the following output: http://pastebin.mozilla.org/349019 the stacktrace is: http://pastebin.mozilla.org/349020 It seams that xpcom is really shuting down.

I get the exact same type of problem (crash) when using a Python thread (PyXPCOM) that tries to instantiate a JS XPCOM component. I was querying the list of logins from the nsILoginManager (which uses JavaScript components) from a Python thread, stack trace below: #0 XPCJSContextStack::Pop (this=0x47fb8f0, _retval=<value optimized out>) at /home/toddw/as/komodo-devel_publishing/mozilla/build/moz191-ko6.14/mozilla/js/src/xpconnect/src/xpcthreadcontext.cpp:105 #1 0x00007fffe688915a in JSCLContextHelper::Pop() () from /home/toddw/as/komodo-devel_publishing/mozilla/build/moz191-ko6.14/mozilla/ko-rel-gtk2-ns-tools/dist/bin/components/libxpconnect.so #2 0x00007fffe688ae56 in mozJSComponentLoader::GlobalForLocation(nsILocalFile*, JSObject**, char**, long*) () from /home/toddw/as/komodo-devel_publishing/mozilla/build/moz191-ko6.14/mozilla/ko-rel-gtk2-ns-tools/dist/bin/components/libxpconnect.so #3 0x00007fffe688bceb in mozJSComponentLoader::LoadModule(nsILocalFile*, nsIModule**) () from /home/toddw/as/komodo-devel_publishing/mozilla/build/moz191-ko6.14/mozilla/ko-rel-gtk2-ns-tools/dist/bin/components/libxpconnect.so #4 0x00007ffff726285f in nsFactoryEntry::GetFactory(nsIFactory**) () from ./libxpcom_core.so #5 0x00007ffff7262988 in nsComponentManagerImpl::CreateInstanceByContractID(char const*, nsISupports*, nsID const&, void**) () from ./libxpcom_core.so #6 0x00007ffff72639e5 in nsComponentManagerImpl::GetServiceByContractID(char const*, nsID const&, void**) () from ./libxpcom_core.so #7 0x00007ffff7272f29 in NS_InvokeByIndex_P () from ./libxpcom_core.so #8 0x00007fffe80cfa9b in PyXPCOMMethod_NS_InvokeByIndex(_object*, _object*) () from /home/toddw/as/komodo-devel_publishing/mozilla/build/moz191-ko6.14/mozil From some digging, I rolled back changes made in bug 477924 and bug 444880 (regarding the JS context stack) and this resulted in the code running successfully (Note: these afore mentioned bug changes were made well after the initial reporters comment date, so it may be just coincidence?).

We have since actively disallowed this behavior... you cannot use xpconnect from other threads.
