Commit message
Allow plugins to throttle delivery of ConfigureWindow requests within reason (LP: #1027211)
Description of the change
Allow plugins to throttle delivery of ConfigureWindow requests within reason (LP: #1027211)
(LP: #1027211) seems to be caused by vsync in the nvidia driver and posting lots of ConfigureWindow requests to the server. The driver really chokes on these for some reason. As a result, two things were happening:
1. The driver slows down quite significantly
2. We get more time to post more ConfigureWindow requests to the driver, which just slows it down even more until it grinds to a halt.
This branch does three things:
1. Introduces infrastructure for plugins to hold a "lock" on delivering ConfigureWindow requests until they choose to release it later (eg, on paint, or on ungrab), while still allowing core to override the plugin's decisions in cases where we actually need to post a ConfigureWindow request to the server in order to continue (eg, some other request is dependent on it). That code was TDD'ed into existence and has test coverage.
2. Optimizes reconfigureXWindow to only configure the frame window if the only thing that happened was that we moved the window. This means that we only buffer up one ConfigureWindow instead of three per call to reconfigureXWindow
3. Implements ConfigureReques
One question that might arise here is whether or not this branch is fundamentally unsafe because we allow the server to get "out of sync" with us. That isn't as much of a problem these days as it used to be. Nowadays we never track the incoming positions from the server to give us a representation of our own internal state, instead that is represented by what we meant to post to the server. So the internal state can never get mucked up. In areas where we do actually need to have our internal state represent what was really last sent to the server, I've structured the code such that in order to do those things, you have to release the queued up ConfigureWindow requests first.
Again, throw this at the wall and see if it introduces any bad regressions. I haven't see any so far.

Confirmed moving windows is much improved. There is no improvement with resizing though. I still encounter exactly the same freezes as mentioned previously:
1. XSync() inside PrivateWindow:
2. XShapeGetRectan
So please either:
(a) Don't touch XShape* in this proposal, and leave resize fixes for a later proposal; or
(b) Fix XShape* properly.
Given the large size of this proposal already, and that a proper fix for XShape should be to simply call it much less often (i.e. only for shaped windows), I recommend (a).
Secondly, I do support the concept of disabling lazy positioning in theory but would have to get my test machine (Atom) for that upgraded and working again before I approve it.

Also, without too much verbosity, why is it we need to implement window movement completely synchronously? My understanding is that waiting and locking should never be required when the user moves a window.
A window move should simply involve two events:
1. Motion event -> move plugin -> send request to X server (XConfigureWindow I think).
and some time later (should not care when):
2. XConfigureNotify (or whatever) -> core plugin -> compiz window position updated.
If this is lazy positioning then maybe I do support it. But historically we seem to have a lot more code than should be necessary to implement movement so I'm not sure.
Daniel van Vugt (vanvugt) wrote : | # |
I mean; my understanding of lazy positioning is that we update the compiz position without waiting for the server to tell us it's done. Therefore the above method counts as non-lazy movement, but also does not require any waiting or locking. I think this is contrary to the proposed and established non-lazy algorithm that does sync for some reason.
If we want to keep lazy mode as an option and it does bypass the server as I suspect then OK. However I think at least non-lazy mode should be implemented as above, so that either way you never need to lock or sync to move a window.

Ah, we actually need to touch it otherwise this proposal won't work
without it, though its not a very big touch, and more or less just a
wrapper around it to make sure that when it is called, we release the
geometry queue for that window.
The reason for that being that XShapeGetRectangles is dependent on us
having the most recent server size of the window actually posted to
the server by that point. If it isn't, then you'll get the wrong
client shape, and that will be incorrectly applied to the frame!

Ah, I think there's a mixup of terminology here.
We're still completely async, both this branch and before this branch.
ConfigureWindow requests are in themselves async, you can post as many
as you want. There's absolutely no waiting for the server.
The problem is that the nvidia driver can't handle it. So instead of
sending it lots and lots of ConfigureWindow requests, we let plugins
"lock out" core from doing that until it makes sense for us to do it.
This means that:
1. In the case of "lazy positioning" being disabled, we just wait
until just before the next frame and post the request
2. In the case of "lazy positioning" enabled, we wait until the window
is ungrabbed.
Both are overridden in cases where we have to ask the server
something. But that's not too often.

It will take me a while to get the code compiled 32-bit and running on the Atom where I tested all the previous lazy-mode regressions. Until then, some style issues:

52 +namespace configure_buffers

2. MOVE_WINDOW (w) - Using macros to declare local variables via side-effect is dangerous and very hard to understand if you're new to compiz. I suggest not doing this in future code. Instead use an explicit:
MoveWindow *mw = MoveWindow::get(w);
3. From a high-level perspective, even if the implementation turns out to be right then I think maybe more analysis was required. This fix is an example of where the medicine could be worse than the disease. It's only useful to nvidia because nvidia is buggy IMHO. And the price to pay is more abstraction and complication that hinders maintainability of the code. We might be better off not trying to "fix" window movement any further.

OK, verified window movement is absolutely perfect on the Atom with this change. So no non-lazy-mode regression to worry about.
Just need (want) to reconsider the style issues and the philosophical point above.

FYI, window resizing on the Atom (i915) freezes just like with Nvidia so that's another good test platform.

It is a little more abstract and complex, yes, however having an unusable system on nvidia is not an acceptable alternative either.
I don't think the code is "unmaintainable", I think it just works in a way that is a tad more complex and different to the way that you would expect. Its fully tested and encapsulated from the other code, so future maintainers don't need to worry about inadvertently breaking it (except for their usage of the client hooks).
In addition, if there are any problems you can just "turn it off" - just don't take a lock on the configure request queue in the opengl plugin.
Speaking of medicine worse than the disease, you just named one of my favourite pieces of music :P (http://

On the same note.
Over my many years of developing compiz, I've often found that the little quirks between drivers, opengl, the way the xserver works, the way specs are implemented etc often means the issues aren't that simple, so its means that the implementation is almost never going to be simple.
If you have a look at any window manager, they are often large and complicated beasts, doing lots of things that you wouldn't even expect a window manager to have to do.
However, window managers often start small and grow to accomadate the quirks in their surrounding environment. The best approach, in my opinion, is to encapsulate complexity into clearly defined areas of the code, so that your handing of corner cases doesn't pollute your main buisness logic or get tangled in-between it. While doing that, ensure that the corner cases are tested codepaths that future maintainers can rely upon the tests when making changes.
This is something that I think compiz really succeeds at. While our test coverage is pretty absymal at best, no other non-niche window manager I can think of is as well tested as compiz is. And its starting to pay off - I've been able to rely on the test suite alone for making some changes now, which is something that I was never able to do.
That being said, I think you're right into looking into any more workarounds for the nvidia problems with ConfigureWindow requests and simultaneous redirected GL. We've found the main cause and root of the problem now, so lets stick with this implementation and work on other things. Window movement is 60FPS here with this applied, so I doubt we can make it any faster :)
