Comments from petrcermak@: This could be because of a redirection (from google.com->goole.ca) in the above log.  It could be also because of "www.google.ca wants to: Know your location" notification.

I've just come across this on an Android perf bot: https://build.chromium.org/p/chromium.perf/builders/Android%20Galaxy%20S5%20Perf%20%283%29/builds/2282/steps/top_10_mobile_memory_ignition/logs/stdio

The error message suggests that it's indeed due to redirection:

  EvaluateException: TypeError: window.__ScrollAction_SupportedByBrowser is not a function
      at <anonymous>:1:8

We've already across similar issues in the past ( issue 540022  and issue 586156), which were fixed by changing google.com to google.co.uk in some page sets (https://codereview.chromium.org/1702463002 by skyostil). I suppose we could do the same here, but I think we'll need to change google.com to google.ca this time.

The core fix here is we should switch from the chrome.gpuBenchmarking.smoothScrollBy to devtool APi for scrolling :-(

Applying the redirect in the page should fix the problem for now, but I agree that longer term these injected scroll shenanigans need to be replaced with devtools commands.

I suspect that the same issue occurs on Windows perf bots:

Win 7 Intel GPU Perf (2): https://build.chromium.org/p/chromium.perf/builders/Win%207%20Intel%20GPU%20Perf%20%282%29/builds/4424/steps/top_10_mobile_memory/logs/stdio

Mythri: Could you please look into this?

Friendly sheriff ping

[perf] Change google.com to google.ca in top_10_mobile page set.

In the top10_mobile page set google.com gets redirected to google.ca.
This sometimes causes problems in telemetry with scrolling. As a short term
fix, replace google.com with google.ca in the page set.

Revert of [perf] Change google.com to google.ca in top_10_mobile page set. (patchset #2 id:20001 of https://codereview.chromium.org/2092443002/ )

Reason for revert:
Caused artificial memory drop in memory.top_10_mobile benchmark.

Sorry if this breaks or flakes other benchmarks. We can re-land (with re-recorded pages) when the dust settles after health plan for this milestone is completed.

[perf] Change google.com to google.co.uk in top_10_mobile_memory and dual_browser page sets.

In the top10_mobile page set google.com gets redirected to google.ca. This
sometimes causes problems in telemetry with scrolling. As a short term fix,
replace google.com with google.co.uk in the page set. We cannot change it
to google.ca because memory_top_10_mobile uses the same page set but with
a different wpr that has a recording of google.co.uk. Updated dual_browser
page set to be consistent with top_10_mobile page set.

Also recorded new wprs for memory_top_10_mobile, dual_browser and
top_10_mobile_memory.
