Running a debug build of Firefox with Mozmill we run into an assertion during shutdown which also crashes the browser: Assertion failure: !"I/O method is invalid", at /mozilla/code/firefox/nightly/nsprpub/pr/src/io/priometh.c:54 Program /mozilla/code/firefox/obj/debug/dist/bin/firefox (pid = 16468) received signal 6.

Mike, could this be related to your changes in bug 648407? I have started a bisect already but if you could give me your impression, I would appreciate it.

Which is indeed. A build before the landing of those patches don't work. Using mozmill 1.5 we do not crash. So something new for Mozmill 2.0 causes it.

As bisecting has shown it should actually be a regression from bug 777554. Changesets before that mentioned one are not able to shutdown the browser. So it's hard to determine.

Essentially right now we are calling recv after the socket has already been closed, resulting in this assertion due to the fact that the fd pointer we are using is effectively toast. The right answer here is to kill off the timer as soon as we are closed so that doesn't happen. Henrik, I still see mozmill thinking that Firefox is still running when it ends, I'm getting a message from python indicating that the application is still running -- but Firefox is actually shutting down normally. I think this might simply be due to how slow things are running on my windows laptop, it's rather old. I looked through the mozrunner and mozprocess code and it seems to all be functioning normally, so I think it's just a factor of slowness. Anyhow, I'd be interested to know if you see that issue or not and if so, we should treat it as a separate issue.

This is also reproducible by running '-m mutt/mutt/tests/js/frame/user_shutdown/tests.ini' with a debug build.
Comment 16•11 years ago

So what is happening here is that we are trying to do our PR_Send after the socket is already closed. But that is happening because there is essentially a race condition between us closing down the application and sending out the last bit of results. In particular, see the code here where the application is already closing and note all the stuff we do: https://github.com/mozilla/mozmill/blob/master/mozmill/mozmill/extension/resource/modules/frame.js#L572 We should either find a way to do less of this at that time or institute our own observer notice for "mozmill wants us to shutdown" which will be activated by "cleanquit" from this file: https://github.com/mozilla/mozmill/blob/master/mozmill/mozmill/extension/resource/driver/mozmill.js#L158 and capture that instead of the "application-quit" notice. Then once our observer that catches our "mozmill wants to quit" notice finishes all the shutdown items and then actually quits the application.

So I did some investigation and tests here and we will have to fix the problem in multiple steps. The current situation is that we have dozen of ways how Mozmill itself is doing a shutdown of the application. We should really centralize that logic in a method which handles shutdown and restart. That way we might be able to cleanly shutdown the application. Once fixed we have to ensure that we always send all of our own data before the bridge gets closed. One thing I'm not that sure at the moment is the 'application-quit-requested' observer notification. I would really like to make use of it to implement the logic pointed out above. But that might cause a hang if at least one listener is not granting the shutdown. It might only happen when further add-ons are installed, and coming up with some modal dialogs - not sure if that is allowed anymore. On the other side such a shutdown would be way cleaner because we can ensure that all components have completed their own shutdown logic, e.g. session store or places. Clint, what do you think?

I think the application-quit-requested observer is the right tool for the job here. While it's possible that some addons may break us here by depending on that, I don't see any cleaner way to do it. Since if an addon were to break us by throwing up a modal dialog/whatever we'd still timeout and capture the error from the python side, I don't think it's a huge deal if that occurs. And I think given that the benefit is a sane shutdown/restart mechanism, the benefit clearly outweighs the danger.

It's quiet interesting to see how JSBridge handled the application shutdown so far. It's really kinda broken. I will give some notes to all of my changes: * As of now we have not deleted the client but only called close() on it when Session.quit() is getting called. That means in some cases we still received broken (might have been cut-off) data from the Python side, which got internally handled via the sandbox, and caused a failure message to be send back. All within JSBridge code. By setting the client to null within the session we can stop that behavior, so no more messages will be accepted. Now we only have to check for a valid client in Session.send(). With that change we can also get rid of the is_closing states. * sessions.remove() indeed removes the session from the array, but it doesn't return the object. So the calling code cannot correctly handle the close action for that session. The cycle collector and garbage collector will kick in at some time but there might be traces left, which keep the underlying client code active. So lets return the session object and let the calling code handle the removed session. As of now none of our code uses the remove() method. So nothing to change for the calling site. * Improve logging for the send() after close() action, so we can see when the server gets closed. Therefore we always route everything through Log.dump().

Oh, and I missed one thing. We really should call session.quit() before closing the socket! Only that way the session has time to finish with everything.

So far my latest changes to mozmill work pretty good and gives us a total pass for our Firefox restart tests. None of the tests fail!! The only issue I have to solve now is the following: * Exec function: '9b43148c-d8fa-11e2-9b3b-3c970e4b31f5 (shutdownApplication)' ******** cleanQuit called with: 2 ************** able to shutdown: false ********* in handler topic: quit-application * Observer topic: 'quit-application' * Stop JSBridge server on port: '45086' * Attempting to send message after session closed: '{"result":true,"data":null,"uuid":"9b43148c-d8fa-11e2-9b3b-3c970e4b31f5"}' Here we are trying to respond to the shutdownApplication() call requested by the jsbridge side. Not sure if we can do anything here, given that we have to respond after the function has been called. But lets see.

That way we trigger the shutdown/restart about 100ms later, and have enough time to send a response through the bridge. I have to clean-up everything now, and probably will do some other minor adjustments.

Ok, so I have nearly finished the patch for this bug. The one and only situation when we will send data after the socket has been closed, if when we are executing the runTestFile() method. Given that it has been started from the Python code, Bridge.execFunction() is trying to answer with the return value. In cases of user restart/shutdown the method will be stopped during application-quit, and is not able to send the result. I don't think that this is important and we can ignore that.

This is mostly ready but before calling it final I would like to run a lot of tests across platforms and versions of Firefox. Andreea and Andrei, please me help me as talked on IRC. Thanks.

Updated version of the WIP patch which enables the dump() calls for suspicious messages after the socked being closed by default. There is no need to run with --debug by default. Please let me all know if you see anything which gets send after the socket has been closed and which gets printed out to the console. Thanks

I think I'm seeing the desired jsbridge attempt message in both mutt testpy,testjs runs. Windows XP32 SP3, one-day old Nightly, latest WIP 1.2 patch. eg. Attempting to send message after session closed: {"result":true,"data":"bridge.registry[\"{cad709fe-a414-42ee-ac93-b367042f9102}\"]","uuid":"b496604f-da7c-11e2-aeb2-647002213455"} If you'd like a log for either testjs or testpy let me know, and I will attach.

Ok, so if you think I cannot go worse, it will happen. As of now I figured out that the most important underlying problem we are facing here with the discard events is happening because a call to restartApplication or stopApplication does not block the test. Those methods are sending a message through the broken and return immediately. That means the test continues until the application gets shutdown in the frame. The only way I can see here is to throw an exception once the restart request has been set. We can catch that special exception in Runner.prototype.wrapper() and set a flag on the Runner object, which indicates that the application is going down. Once a test module has this state set, we do no longer execute other tests or teardown methods, but wait for shutdown/restart. That way no further events will be triggered, which will most likely become discarded. Clint, what do you think?

I ran with mozmill -m mutt/mutt/tests/js/tests.ini -b nightly_path --debug, on Linux 64bit. First try failed due to that dialog of multiple ff copies, the second passed: Didn't get that line with "Event discarded". I can add the log if needed. Do you need to be ran in another way?

Ran the restart tests as well and all works fine on this Linux 64bit for me. All tests passed.

I think that's the sanest shutdown/restart idea Mozmill's ever had. +1. I'll try to give it a whirl on windows at some point today.

Alright. Here an updated version and the first real patch! I found even some more problems in the shutdown logic and cleaned those up. Restart tests seem to work pretty fine. We have tested that on all platforms now. User shutdown tests might work, but it's still not guaranteed. It will be fixed in a follow-up bug for Mozmill 2.1. Clint, I believe that I have removed any tracing code from that patch. But please keep an eye on any left-over debug statements. I decided to upload the patch already now, to let you all play with it while I'm away the next couple hours.

On Windows XP32 SP3, mozmill-env 2.0rc4, latest Nightly, and Patch v1 in comment 45 applied to my mozmill repo, I'm seeing this failure output, one for each mutt test in the manifest. Javascript Failures: Exception: "[JavaScript Error: "missing ; before statement" {file: "resource://mozmill/modules/assertions.js" line: 169 column: 48 source: " aResult.name); "}]" (None) I see this both when running `mutt -m`, or `mutt testjs`. Anyone else on Windows seeing the same?

And to clarify, when I switch my repo branch from Patch v1 to master, and run the mutt tests same way, the tests run fine.

There seems to be some lingering issues after this land. Thanks Jonathan for pointing this out in bug 764640 comment 37 (and for the logs via email). I'm seeing the same thing: Before this patch landed: > mutt testjs -b /Applications/FirefoxNightly.app/ > ... > RESULTS | Passed: 56 > RESULTS | Failed: 2 > RESULTS | Skipped: 0 > ... > Total passed: 56 > Total failed: 2 > Total skipped: 0 With this patch I'm seeing some discrepancy between JS and final results logged: > mutt testjs -b /Applications/FirefoxNightly.app/ > ... > RESULTS | Passed: 58 > RESULTS | Failed: 2 > RESULTS | Skipped: 2 > ... > Total passed: 60 > Total failed: 2 > Total skipped: 2 I have not noticed this before.

The discrepancy seems to come from the frame/restart tests:

Seems to be a problem with mutt reporting the total results erroneously. It logs a PASS on a skipped test in setuptest_skip.js
