Crash while showing context menu in Flash plugin on loading new page [@ ns4x
Plugin Instance::Handle Event]
Build: 2002-12-04-04 Platform: OS X 10.2.2 Expected Results: Selecting a menu item in the contextual should do nothing. What I got: The application crashes Steps to reproduce: 1) Go to http://www.kartoo.com 2) Click on a previous saved bookmark 3) Before that page loads, control click on the flash object and continue to mouse down 4) The bookmarked page should load and the flash contextual menu should still be present. 5) Now, select a menu item from the contextual menu. 6) The application should crash.
does this only happen in chimera? how about other mac builds? how about 10.1.5?
Whiteboard: [need testing]
Yes, this is a chimera only issue. Tested under both OS X 10.2.2 and OS X 10.1.5.
Chris / beppe: Does this still happen? If yes, have you contacted Macromedia?
Priority: -- → P2

Still occurs in the 2003-08-10-02 Camino NB.
Camino 2003-08-12-02 / Flash player 7b... crashes with same stack
Severity: normal → critical
Summary: A crash can occur when selecting a menu item from a Flash plugin contextual menu → A crash can occur when selecting a menu item from a Flash plugin contextual menu [ns4xPluginInstance::HandleEvent]
The stack shows us crashing after calling HandleEvent through a mouseDown. Could someone with a Mac build could set a breakpoint during this call to mouseDown and see if we are passing any bogus data to the plugin?
See also bug 183313, which has a similar but not identical stack for the same URL. My most recent crash on that site failed to generate a Mac OS X crash log, but Talkback ID is TB5392537W. (I can't get it to crash again because now I'm always getting the Camino contextual menu, bug 192276, for any Flash I attempt to ctrl-click)

any recent updates here?
I wonder if we could prevent this particular crash on the Camino end by fixing bug 168065? Not sure the stack is really much different, but here's a more modern one from 10.3.9 and yesterday's 0.9a2+ (1.8 branch) nightly....
I think the key here is that we're showing the plugin's context menu but tearing down the plugin while loading the new page at the same time.

I'm not sure whether the browser or the plugin should be the one to stop this happening -- Michelle?

If you try to reproduce this in Mac Firefox 1.0, you can see that the browser will not move off of the kartoo page until the mouse is released. If Camino could do this as well that would fix this bug, I think.
Firefox 1.5 will behave the same way that camino does now (CFRunLoop fallout).
I think that the browser should not unload the plug-in until the mouse is released. This is the behavior I see in other browsers. Also, this is what Samuel Sidler proposed in bug 168065.

(In reply to comment #15) > I think that the browser should not unload the plug-in until the mouse is > released. This is the behavior I see in other browsers. Is this something we can have done by 1.0? If it can/will fix a crash, I think it's worth it even if we want to go another route after 1.0.
We should investigate not firing PLEvents for certain runloop modes.
does this crash in ff as comment 14 suggests? If so, i can't see this happening on the branch soon with the lockdown. also, should this be re-directed to core?
Flags: camino1.0? → camino1.0-
Yeah, this crashes Firefox too.

Josh, can you look into this and help us understand how severe this is and how risky a fix would be?
Josh, if by code inspection, you can find a way that this might be more common than the steps provided in comment 0

I just filed a bug which seems to have a similar stack to this one - (contains ns4xPluginInstance::HandleEvent(nsPluginEvent) - Bug 314558. I didn't get talkback but I did get two apple reports which I attached to that bug.
FWIW, I've got an easier way to repro this (without the timing issues of loading the bookmark vs the context menu in comment 0): 1. Go to http://online.tvguide.com/listings/grid.asp 2. Click on the next or previous arrows to cause the grid to reload 3. Ctrl-click on the "arrow" animation to bring up the Flash CM 4. After the new grid has loaded, click elsewhere in the page to make the CM close. 5. Camino crashes.
So wait. Is the problem that we're spinning the Gecko event loop here when Gecko doesn't expect it to spin, basically? This has come up before, no?
Can you reproduce this bug with Flash Player 9r16 on Mac PPC? If yes, could you clarify if you are following the steps to repro in comment #1 or other steps? The tvguide site in comment #25 no longer appears to use the Flash Player.
bug 319857, which may be a dup, suggests this was fixed by threadmanager checkin, in which case it should work with a trunk build after 2006-5-10. Do you still see this bug with a current trunk build? Or http://archive.mozilla.org/pub/firefox/nightly/2006-05-12-06-trunk/
This appears "fixed" on the trunk because the "fix" is actually a symptom of bug 356720, since clicks to any native stuff (menus, scrollbars, context menus) stops Gecko entirely. We need to make sure this "fix" doesn't regress when bug 356720 is fixed.
Josh, can you please verify this bug? Let's get this moving if need be.
I don't see any crash using Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.9a9pre) Gecko/2007100904 Minefield/3.0a9pre and r47 flash and using r60 flash.
Marking fixed, but we need to get it verified.
