Fix CGSPrivate (again)

[tiennou]

I've did it again. In my eagerness to silence warnings, I broke CGSPrivate.

I was trying to fix the Cube issues (since @skurfer was kinda expecting that from #2144) and noticed a hard crash (the same as #1811). So this one stops the crash, but the animation is still horrible (here I can see it jump down (topscreen/topwindow distance seem to become bottomscreen/bottomwindow) and turn to some invisible window side before getting a hold of itself...

I'll try to pinpoint what's going wrong with it, but I have no clue whatsoever about what. is. going. on.

I'll merge that ASAP because it's a quick fix. Just wanted a heads up to you guys.

[skurfer]

OK, didn’t have a chance to look at this until now and didn’t catch the insta-merge. No problem with it, but you should probably update the release notes when doing this in case we miss it.

[tiennou]

You're right. I didn't actually think it was worth mentioning an unreleased bug fix ;-).

[pjrobertson]

Sorry I've been off the radar.
I've tried again and again to fiddle with CGSPrivate but it's always come
back to haunt me, hence why it's never been changed!
Hopefully you've got something working now... other places to check to make
sure they work are:

• setup assistant
• QS built in notifier

Setup Assistant and built-in notifier appear to be working, though I am periodically seeing this in the Console.

Still trying to track down exactly what triggers it.

[tiennou]

Non-main thread access to AppKit ? I chalked it up to "not this" because I had already seen it ;-).

[pjrobertson]

Is that just with Nostromo, or other interfaces as well? Maybe try running QS with a debug-built version of Nostromo so you can see exactly where the call in the Nostromo plugin is

2015/11/10 9:00:05.312 AM Quicksilver[3870]: void CGSUpdateManager::log() const:  18  Nostromo                            0x000000011440c603 Nostromo + 9731

[tiennou]

The hidden Nostromo call may (or may not) be expandWindow:. I was running Bezel and saw that too so I don't think it's interface-specific (I would say it's resizing-interface-specific, but there might be other symptoms). The issue lies here (from @skurfer stack) :

19 -[QSResizingInterfaceController adjustWindow:] + 320
20 -[QSWindow makeFirstResponder:] + 241
21 -[QSInterfaceController showArray:withDirectObject:] + 267

One of there should be wrapped in a QSGCDMainAsync (QSWindow looks half-way decent to me). By the time this thread finishes completes execution, it leaves its transaction behind, triggering the log. This is a consequence of the "always-threaded-execute" change we might have done, combined with dispatch queues and AppKit API all over the place.

[pjrobertson]

Cool, thanks for the explanation. I'm glad you understand what it means :D
