Crash Data

Seem to have found a reproducible Flash Hang. Someone should take a look. Steps to Reproduce, should be semi-easy for a Mozilla person. 1) Visit large flash site. 2) For instance Workday: https://www.myworkday.com/vhr_mozilla/logout.flex#%3Bvhr_mozilla%3Blogout.flex 3) Enter Username and Password Result: 1) Browser Hangs on Login - Hang lasts for a long time. 1+ min 2) You are allowed to login to the site, but upon logout, browser hangs. Hang lasts for a long time. 1+ min Going to Activity monitor and force quitting the Shockwave/Flash process brings the browser back to a functioning state. I can help get any Mozilla employee access to Workday. Let me know when you start working on the bug and I'll make sure you have access.

Bret: Can you please let us know which version of flash you are running?

should add this info to the about:support page for easier copy/pasting :).

Not much interesting there: mozilla::plugins::PPluginInstanceParent::CallNPP_HandleEvent_IOSurface is waiting for the plugin process to respond, so we'd need information from the plugin process.
Ok, so we have a reproducible hang on Aurora but it doesn't seem to exist when he runs Nightly/Beta or Release. Is there nothing more we can do here? Bret has indicated that we can run instrument whatever we need to on his machine. I sort of feel like we have an opportunity to do some analysis to understand what is going on. Are we saying that because the plugin process is not responding, there is very little we can do next. Do I tell him to upgrade to Flash 11?
We can get a regression range from nightlies. Even sitting at his machine there probably isn't a lot we could discover, because without Flash symbols it would be very hard to figure out what's going on. We could try a debug build to see if any assertions or interesting things show up, otherwise we'd have to ask Adobe to look at it.
Ok, thanks. I am going to have him upgrade to Flash 11 in case that changes something. The debug build is a good idea. It's going to be hard to get Adobe to look at it without more info.
Maybe Jet, can pull a few strings with Adobe :)? jet@mozilla.com - Engineering Manager Layout/Gfx
Ben - The main problem here isn't that Flash hangs. It does that. The main problem is that we aren't killing the plugin process. I sat with Bret the other day and he showed this to me. We let it sit for about 2 minutes and the browser never killed the plugin process. When I used the system monitor to kill the plugin, the browser came right back. So why aren't we killing Flash in this instance? Is there something special about the call stack? (Also both of the processes were totally idle which makes me think that there might be some kind of deadlock involved.)
Just upgraded my Flash Plugin to: File: Flash Player.plugin Version: 11.0.1.152 Shockwave Flash 11.0 r1 With the above steps, the plugin is now killed when it goes unresponsive. The workflow looks a little strange, but at least the browser is not hanging. New Steps: 1) Visit large flash site. 2) For instance Workday: https://www.myworkday.com/vhr_mozilla/logout.flex#%3Bvhr_mozilla%3Blogout.flex 3) Enter Username and Password Result: 1) Site begins login, throbber rotates 2) Killed plugin graphic appears for a fraction of a second 3) Site completes login Same basic flow happens on site logout. The plugin is killed and the graphic appears for a split second, then site logs out. So, overall, this is working, but seems a little shaky.

Bret: It would be useful if we could get a guest login into the workday system so we can try to reproduce on some machines here. Who do I talk to about that?
Brendan asked me to add Chris to this bug (at least I think this is the bug he meant). Bret: Can we get a guest login?
Why are we using the synchronous plugin-painting path here? I thought that was only for 10.4. I don't have any idea what might be hanging flash. I think this needs some quality time in gdb. It's not obvious to me which thread is the main thread in the crash report in comment 12. Can anyone else repro this? Bret, are you in SF or MV? If it's only on your machine, we should send someone by to poke at this.
A few notes - Matt tells me we fall back on the synchronous painting path when we're not using GL layers. - based on comment 0, it looks like Bret is getting GL layers - but comment 4 shows a basic manager - but sometimes we create temporary layer managers to paint content, which are always basic Another thing to check.
Bret, are you using a persona?
The sync path is expected. We decided to pref async off, See bug 663259 Comment 44. This decision was made because of unresolved bugs.
Re: Chris Jones. I'm in Europe until Nov 17th. Could mail my machine to someone if it's urgent. Re: Matt Woodrow. I am using a persona. Aurora Australis, looks awesome.
I believe that on OSX we always draw personas using a temporary BasicLayerManager, that would explain the use of BasicLayers and the callstack coming from TitlebarDrawCallback. However if we're always on sync painting because of a pref then this probably won't have any effect.
It appears that we're painting the plugin instance with the BasicLayerManager. That doesn't seem right, unless the persona uses flash (*shiver*). This (http://www.getpersonas.com/en-US/persona/67532) appears to be the person; does anyone know how to view its source without installing?
Bret, can you send Marcia some login information for Workday and we can try and reproduce in the lab?
Sheila, working on getting her access now.
