This is similar to the crash seen in bug #549767, comment #112 in the sense that deactivation happens off the main-thread, but similarities ends here IMO. Looking at this further, note frame 11: It is a call to Doom() after WriteDataCacheBlocks() failed. Hence it *may* be related to bug #592422 although it's not clear to me how. I would rather expect this crash to be triggered by closing/flushing wysiwug-channels off main thread (I believe I saw something related to that not too long ago). Deactivating an entry off the main-thread shouldn't be an issue though, so this is another indication that the book-keeping in the cache is not thread-safe.

There might be a variant of this crash in bug 615020, since they're both cache-related.

Right, this seems to be related to bug #599127. But as you say, deactivating entry on a background thread should be safe. I'll have a look at it...

http://tinderbox.mozilla.org/showlog.cgi?log=TraceMonkey/1291253758.1291256642.8334.gz May or may not be interesting in that it has two crashes, one the normal DeactivateEntry and another going through nsCacheService::Shutdown.

This looks like the same crash, but it's on ts rather than ts_cold: http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1291287379.1291287842.2048.gz
Comment 30•14 years ago

Michal, I have a theory why we sometimes deactivate the same entry twice: Refer to remark about frame 11 in comment #5 - in nsDiskCacheStreamIO::Flush() we call DoomEntry() if WriteDataCacheBlocks() fails. In some cases (when entry is considered to be unused) nsCacheService::DoomEntry_Internal() calls DeactivateEntry() which eventually deletes the entry. However, if the entry was deactivated for some reason before nsDiskCacheStreamIO::Flush() is called we end up deactivating twice. For this to happen WriteDataCacheBlocks() must fail (which *may* be related to bug #592422, ref comment #3). And the entry must have been deactivated while it was written, which could happen via nsCacheService::Shutdown() -> ClearActiveEntries() or nsCacheService::OnProfileShutdown() which calls DoomActiveEntries() and then ClearDoomList(). (There may also be other paths.) (Note also that ClearActiveEntries() removes descriptors and requests from the entry, making it unused which will cause DoomEntry_Internal() to call DeactivateEntry() - ref second paragraph). I see at least two different ways to deal with this: 1) check if entry is already deactivated in DeactivateEntry() and exit early 2) sync up with cache-io thread in Shutdown() and OnProfileShutdown() (like I'm suggesting to do in bug #549767) to let Flush() finish first. Or maybe we should do both.

I think we need to block on getting our thread safety straight in the cache code, especially given that we now do much more off the main thread in the cache.

The problem is in the way we forcibly deactivate entries during shutdown. We call DetachDescriptors() (which removes all descriptors but input/output can stay open) and then DeactivateEntry() (which deletes the entry). Deletion of the binding is posted to the appropriate thread and it happens when the entry is already deleted. The binding releases the reference to streamIO which causes writing to and dooming the released entry: #0 nsCacheService::DoomEntry (entry=0xeb025220) at /opt/moz/hg/netwerk/cache/nsCacheService.cpp:1866 #1 0x0138e07c in nsDiskCacheStreamIO::Flush (this=0xee920680) at /opt/moz/hg/netwerk/cache/nsDiskCacheStreams.cpp:532 #2 0x0138dc43 in nsDiskCacheStreamIO::ClearBinding (this=0xee920680) at /opt/moz/hg/netwerk/cache/nsDiskCacheStreams.cpp:438 #3 0x013838c8 in nsDiskCacheBinding::~nsDiskCacheBinding (this=0xee920640, __in_chrg=<value optimized out>) at /opt/moz/hg/netwerk/cache/nsDiskCacheBinding.cpp:136 #4 0x01383927 in nsDiskCacheBinding::~nsDiskCacheBinding (this=0xee920640, __in_chrg=<value optimized out>) at /opt/moz/hg/netwerk/cache/nsDiskCacheBinding.cpp:139 #5 0x01383686 in nsDiskCacheBinding::Release (this=0xee920640) at /opt/moz/hg/netwerk/cache/nsDiskCacheBinding.cpp:115 #6 0x0282bbd6 in nsProxyReleaseEvent::Run (this=0xeb067100) at nsProxyRelease.cpp:52 #7 0x02896c8d in nsThread::ProcessNextEvent (this=0xee8c6820, mayWait=1, result=0xee6ff21c) at /opt/moz/hg/xpcom/threads/nsThread.cpp:626 #8 0x02827275 in NS_ProcessNextEvent_P (thread=0xee8c6820, mayWait=1) at nsThreadUtils.cpp:250 #9 0x02895d5e in nsThread::ThreadFunc (arg=0xee8c6820) at /opt/moz/hg/xpcom/threads/nsThread.cpp:278 #10 0x00359757 in _pt_root (arg=0xee88a240) at /opt/moz/hg/nsprpub/pr/src/pthreads/ptthread.c:187 #11 0x0026b925 in start_thread (arg=0xee6ffb70) at pthread_create.c:297 #12 0x07b0407e in clone () at ../sysdeps/unix/sysv/linux/i386/clone.S:130 The stack with wyciwyg channel is an alternate crash but the problem is the same. This patch forces closing of the output when we call DetachDescriptors(). The tricky and ugly part of the patch is the nsIDiskCacheStreamInternal interface. nsDiskCacheOutputStream::Close() grabs the lock and we need to call it under the lock, so to prevent reentering the lock I had to create a new method. I pushed the patch to the try server and there are few failures that seem to be unrelated.

Anyway, with that patch we still call Flush() and Doom() for already released entry. The fact that it doesn't crash is just a luck by chance...
Comment 160•14 years ago
|

Ahh - of-course: Flush() (and the following Doom()) is not called on the cache-io thread, hence draining it doesn't help in this case. Is it the STS-thread? I guess waiting for the STS-thread to drain is not a proper way to deal with this... I do have a funny feeling about this approach though. IMO, at the very least it should make clear that DetachDescriptors() has the side-effect of closing the output-stream (e.g. by renaming the method, or at least documenting properly). To be constructive: Why not rather take action in nsDiskCacheDevice::DeactivateEntry()? Afaics this problem only applies to the disk-device, and DeactivateEntry() is called from the same places as DetachDescriptors(). From nsDiskCacheDevice::DeactivateEntry() you have access to the nsDiskCacheStreamIO object via the binding. Moreover, calling nsDiskCacheStreamIO::ClearBinding() may be sufficient to prevent this problem because if calls Flush() and then clears |mBinding|, preventing further writes to the outputstream.

Following up on the hint in comment #160, this patch gave me the greenest tryserver-run in a long time (says a lot about my other patches I guess, but nevertheless...) - 08e2016af8f3 on tryserver. Michals procedure for reproducing do not crash with this patch applied. The code-block added to nsDiskCacheDevice::DeactivateEntry() is also found in dtor for nsDiskCacheBinding and could probably be stuffed in a method named nsDiskCacheBinding::DetachIoStreams() or similar. I also removed the redundant call to UpdateRecord() in Flush() (as indicated in the comment) but this change has no relevance to this problem and could be removed.

Yes, FF seems to crash only in case of disk cache, but IMO it makes sense to always close the output.

Per discussion with Michal, and in the interest of getting rid of this random orange and landing this blocker bug fix sooner rather than later, I landed this today. Michal believes his patch gives us a more consistent approach here, but if that for some reason doesn't work out he'd be happy to take Bjarne's alternate fix here. But until then, this is fixed. http://hg.mozilla.org/mozilla-central/rev/82ac194b7537

Comment on attachment 501491 [details] [diff] [review] Alternative approach, v2 Fwiw, I think bug #620660 should be landed before we can state too much about these random oranges related to the cache. Current code randomly executes cache-related operations *after* internal datastructures of the disk cache has been freed, clearly carrying the potential for weird problems. The patch has been waiting for review for quite some time so I guess it will happen any day now. Since this bug has been reopened I also take the liberty to change reviewer on my alternative (and IMO more light-handed) patch. Bz already reviewed the landed patch and may be able to do a quick one for the alternative as well since he knows the problem-area.

We don't have access to the output stream from the device. So IMO this is still a disk-cache solution only.
Comment 176•14 years ago
|

With this approach it is up to the device to ensure it has enough information to "close" its IO. In the disk-cache case, nsDiskCacheBinding holds a ref to the nsDiskCacheStreamIO-object, which is sufficient to "shut down" (or rather: "prevent further") IO for the disk-cache. The offline-device would have to add appropriate info to nsOfflineCacheBinding, then implement its own version of DetachStreamIO() to use this info to close IO. The memory-device might not need this, hence it can avoid implementing DetachStreamIO(). It is pretty much what you also do, except that the necessary info is per device and not kept in nsCacheEntryDescriptor. We avoid the new interface and the explicit QI. Moreover, with this approach a device can do more than just close the outputstream for an entry, if this is necessary or desirable for whatever reason.

Previous patch closes output only when detaching descriptors during shutdown. In case the cache entry is closed explicitly with Close() instead of just releasing reference, the entry is deactivated without closing the output and could crash in certain situations. So we need to close the output whenever we remove the descriptor. On the other hand I don't think that this was the cause of the latest crashes since I haven't find any place where we would call Close() directly.
