No, for 2 reasons.One, we [NSApp mainApplication] before turning on the sandbox. (Yes, that's bad.) Two, the essence of the problem is that no thread in the renderer ever does a MessageLoopForUI or [NSRunLoop run].
In the longer term we want to remove all Cocoa from the renderer. But in the short term, for this 'spin' problem, I think Avi has it right -- "MessageLoopForIO in renderer_main in a non-main thread and make a MessageLoopForUI on the main thread." jrg On Fri, May 22, 2009 at 11:36 AM, Mike Pinkerton <[email protected]>wrote: > > Does the problem go away if we disable the sandbox? > > On Fri, May 22, 2009 at 2:02 PM, Jeremy Moskovich <[email protected]> > wrote: > > I just pinged Avi about us, my guess is that the Sandbox is blocking > > connections ot the Window Server. > > Adding (debug deny) to the sandbox spec file will print messages to > console > > when things like this happen, I'll add a note about that to the Wiki > > (http://dev.chromium.org/developers/debugging-on-os-x). > > Best regards, > > Jeremy > > > > On Fri, May 22, 2009 at 10:54 AM, Avi Drissman <[email protected]> wrote: > >> > >> A visitor to IRC pointed me today to http://crbug.com/11319 , where > >> renderers are marked as "not responding".
