can't reproduce on Nexus 6P

From the microdump address space stats: by the time the microdump was taken there actually should have been (just about) enough address space to satisfy this allocation (there's just one single 64MB chunk available, and only 149MB free total). But, there's loads of failures from the GPU driver between the initial OOM and the microdump - it's likely that we actually were out of memory at that point, but while the GPU driver was failing it unmapped some stuff.

Unfortunately we don't dump the full address space map in a microdump so it's hard to see what was taking up all the space (minidumps do have this).

The page doesn't appear to use an unusual amount of memory on my devices, but it also doesn't appear to load properly (it renders a logo, background, and a weird empty frame, and spews a bunch of JS errors) so it's hard to tell whether something's going wrong or not.

It's possible we're tickling a GPU driver bug here that's making it misbehave and map too much stuff, but that's just a guess. We either need to be able to reproduce this (probably on the same device/build if it's a driver bug), or to get more data about what's mapped at the time of the crash (from a minidump, if there's a way to get it to generate that on a production build, or by doing a special build for the reporter that dumps it some other way?)

satyavathir@ would you like to verify if this issue could be reproduced?

I have checked on Samsung S4 Verizon(SCH-I545)/LRX22C with WebView :43.0.2357.121 (system), 58..0.3029.83 (Stable) and 59.0.3071.71(Beta). I didn't see any crashes on app launch.

I have also checked few things:
Kept the app in #0 idle for 3 to 5 minutes - no crashes
Back grounded the app, launched other WebView apps, launched app #0 from recent apps - no crashes
Clicked the links(like Facebook, G+, twitter etc) within app - no crashes
Clicked on the deck of apps- > it takes to Play store - no crashes 

May be we should find out more info, from the user? 

Thanks!

Does the device you tested this on have the same build fingerprint:
samsung/ja3gxx/ja3g:5.0.1/LRX22C/I9500XXUHPK1:user/release-keys

I suppose, you can't reproduce because different GPU:
Samsung Galaxy S4 I9500XXUHPK1 has PowerVR SGX 544MP, but
Samsung S4 Verizon SCH-I545 has Adreno 320GPU.

Thanks for confirming that.

Satya, do we have one of the S4 variants with the Exynos SoC and Adreno GPU? I think those might not be sold in the US. The one you tested is the Snapdragon SoC with PVR GPU, so if it's a driver issue as I somewhat suspect then it won't repro there.

torne@ - we have only S4 Verizon/L for WebView (we have many S4's, mostly < L versions). I will recheck all remaining S4's to see, if any of these matches to the exact GPU & update the bug. 

Thanks!

satyavathir@, the folks in India (ET) may have a GT-I9500 with L.

battun@, can you work with them to repro?

I have checked on Samsung Galaxy S4 Verizon(GT-I9500 PowerVR SGX 544MP)/LRX22C with WebView :43.0.2357.121 (system), 58..0.3029.83 (Stable) and 59.0.3071.71(Beta). I didn't see any crashes on app launch.

I have also tried by keeping the app back ground, idle for 5 to 10 minutes - we don't see any crash. 

Thanks!

Device fingerprint: samsung/ja3gub/ja3g:5.0.1/LRX22C/I9500UBUHOK2:user/release-keys

Thanks!

Thanks for trying.

peabeynarovich@, since we can't reproduce this the only way we'll be able to figure out what's happening is if you can get us some more information. A memory-infra trace might help: https://chromium.googlesource.com/chromium/src/+/master/docs/memory-infra/README.md

Hi

How to start chromium memory trace on Android WebView app?

Thank you for providing more feedback. Adding requester "torne@chromium.org" to the cc list and removing "Needs-Feedback" label.

Assuming that you can't find a userdebug ROM for the device, you would need to add the following to your app initialization code:

WebView.setWebContentsDebuggingEnabled(true);

Then, when the device is connected via usb to a machine running chrome, browse to:

chrome://inspect?tracing

You should see a list of WebViews in your application, along with a "trace" link. Clicking on the trace link and then on "Record" should give you a list of categories to trace. If you select the memory-infra category, record a trace, and then save it to disk, the file produced should be the information we require.

Hi again

Trace file is attached.

all the leaks are mappings from /dev/pvrsrvkm, that's the powervr graphics driver. However there is no growth in chrome's internal tracking, meaning chrome/webview considers that it has freed all its allocated resources (or at least there is no growth). So this is likely a gpu driver bug.

Can you open chrome browser on the device, go to chrome://gpu, and print that page as pdf and attach it here?

Don't really have high hopes of actually having this fixed, since device has probably long past oem support, and it's unlikely to get driver fixes, and finding workaround is hard.

Adding needs-feedback for the pdf of chrome://gpu

I can't create pdf because I didn't find menu Share. 
I have made screenshots (attached)

we have one s4 with the same gpu, but it's stuck on kitkat..

played with the kitkat device a bit

test shell leaks plenty of memory, expanding the avoid_egl_image_target_texture_reuse workaround does not help, disabling texture reuse in makes the rate of leak much much faster. so this is driver leaking some memory each time is created and shared. And on kitkat at least, KHR_fence_sync is blacklisted, so technically, webview doesn't even have enough extensions to operate in GL mode (although the code that checks for that doesn't respect the blacklist)

wonder if we should just blacklist hardware acceleration altogether on this config..

is this still an issue? is WebView memory still leaking on Samsung Galaxy S4? 

Yes, WebView memory is still leaking on Samsung Galaxy S4 (Chrome version: 62.0.3202.84)

It seems boliu@ had investigated this and there is no obvious way from WebView side to get this fixed. Potential workaround is blacklist hardware acceleration on this config per c#28.

cc boliu@ in case he want to make decision.

I'll change the status to available since the issue looks confirmed already.

Changing to available + p3 ensures that this will never be looked at by another team member. Is this configuration popular? Does it merit real action from our team (i.e. blacklisting the hardware)?

Hmm, S4 still shares reasonable amount of the market from the public resource (0.8% [1]), but with this GPU, maybe only Samsung knows. boliu@, assigning this to you, feel free to reassign though.
