This is very surprising, as I only moved code around. I'm going to bisect again..

Comment 7 by danakj@chromium.org, May 31 2018

Status: Started (was: Assigned)
I will bisect within the patch locally.

Comment 8 by danakj@chromium.org, May 31 2018 

memory:webview:all_processes:reported_by_chrome:gpu:effective_size locally with android-webview:

with --pageset-repeat=1 i get 2.1MB before and after the patch
with --pageset-repeat=3 i get 2.1MB before and 1.5MB after the patch

..

Comment 9 by danakj@chromium.org, May 31 2018 

I've been trying this all day, the 5minutes per test-run, 15minutes to run 3 times and get something more reliable thing has been a BLAST.

Without the patch, what happens is it is consistently always 2.1MB.
With the patch, it's usually 2.1MB too, but sometimes it's < 1MB so we end up with this average of 1.5 on 3 runs.

I don't know why the memory /increased/ on the bots tho instead.. but they show a lot of variance compared to before, so at least that part is consistent...

The only thing that I can see as possible is the move of glFinish() from LTRP to LayerTreeHostImpl.. but that means other users of LTRP (ie the VideoFrameResourceProvider) don't have that glFinish() anymore, and maybe it was doing.. something.. over there by accident, if that code even runs.

I'm still in the dark though. As it's flaky and takes 15min to even try something... yeah.

Comment 10 by danakj@chromium.org, May 31 2018 

Switching gears.. Looking at the traces instead. The after trace has 2.7 more memory in cc.

1.8MB in tile_memory and 0.9MB in image_memory. So seems like some tiles are not deleted. I see in fact 2 tiles (884KB each) listed in the trace after that aren't there before.

But if cc is claiming responsibility you'd think it still considers them part of its ResourcePool.. and thus it didn't delete them and it's not a flush/finish problem..?

Comment 11 by danakj@chromium.org, May 31 2018 

Adding prints at the calls to ShallowFlushCHROMUIM() they all have a context_provider as we'd expect so they do call flush, not avoiding it somehow when the LTRP would have succeeded. ~VideoFrameResourceProvider does not occur.

Comment 12 by danakj@chromium.org, May 31 2018 

I think I am out of ideas. Here's the call site changes:

~LayerTreeResourceProvider: Finish() moved. This never even runs in my local test. Nor LayerTreeHostImpl::ReleaseLayerTreeFrameSink() 

HUDLayerImpl::UpdateHudTexture resource pool creation updated: Does not run.

LayerTreeResourceProvider::PrepareSendToParent: uses a passed in context, but is not conditional, and if context changed then the one in LTRP before would have been invalid and crashed

ResourcePool::ResourcePool(): using_gpu_resources_(resource_mode == Mode::kGpu) used to happen. All uses of this changed to !!context_provider_. Creation of ResourcePool before was if(context) { kGpu } else { kSoftware }, so ResourcePool was always created, and context!=null === kGpu.

ResourcePool::EvictExpiredResources() calls flush on the context directly if not null. I printed and all cases this is reached the context is non-null (android so expected..) so it is calling the flush. LayerTreeResourceProvider would have had a context too of course so it would have as well, since it is created at the same time as the ResourcePool.

LayerTreeHostImpl::ReclaimResources() is never called when !visible_ in my test locally.

and that's it so..

About to WontFix this and claim "timing" but +boliu FYI. And double checking 1 more thing..

Comment 14 by danakj@chromium.org, May 31 2018 

There's also 1 MB in the gpu category in the after trace, which is 2 textures. I guess that's the one the alert is pointing at, even though there's the 2 extra in cc too.

These 2 must be disowned by cc, but haven't yet been deleted in the gpu. That is more likely I guess that a ShallowFlushCHROMIUM didn't happen yet maybe? But printfs say they are happening the same.

Also verified that the PrepareSendToParent is using the same context always that the LayerTreeResourceProvider was handed before, and it is.

For fun:

Ok 1 more observation, the 2 GPU textures that aren't shared with anything else are on a different share group than all the compositor textures. In the before trace that 2nd share group doesn't exist.

So it's not the renderer compositor's textures showing up there..

Status: WontFix (was: Started)
The same build saw this test become less noisy/use less gpu memory: https://chromeperf.appspot.com/group_report?keys=agxzfmNocm9tZXBlcmZyFAsSB0Fub21hbHkYgICQkcj6twoM

It started getting noisy/larger on a range with another meaningless change to LayerTreeResourceProvider.

I really don't think there's more to be done here. The test should maybe do a glFinish() before collecting a memory dump or something to get a more consistent result.
