Bug 2027803 - Enable stencil navigation cache on nightly. r?nbp!
48 bytes, text/x-phabricator-request
Details | Review

The next step is to enable the stencil navigation cache pref on nightly, and track the telemetry results to see if things are working well.
And also at the same time enable the code on non-nightly in bug 2024970 to prepare for the experiments.

Pushed by abutkovits@mozilla.com: https://github.com/mozilla-firefox/firefox/commit/ff6ad8cf184e https://hg.mozilla.org/integration/autoland/rev/756632401c08 Revert "Bug 2027803 - Enable stencil navigation cache on nightly. r=nbp" for causing high frequency failures at browser_dbg-event-breakpoints.js.

The test seems to be timing dependent, and has some race between the assertion and the react/redux update.
After the assertion fails, the selected line becomes 87 in the UI, so the expected update is surely happening, but the testcase is not properly waiting for it.
So possibly the cache is affecting some event that the test is waiting for.

the test has been failing intermittently, and has been skipped on various configuration already for similar intermittent or permanent failures.
I'll disable it.

Could you consider nominating this for a release note? (Process info)
We could include it in the nightly only release notes.

Flags: needinfo?(arai.unmht)

Release Note Request (optional, but appreciated)
[Why is this notable]: Improves the page load performance, at the cost of memory consumption. Also affects how the cache of the JavaScript works, especially in terms of DevTools Network Monitor, WebDriver APIs, and the WebExtensions API.
[Affects Firefox for Android]: Yes
[Suggested wording]: Introduced an in-memory cache for the JavaScript compilation result, which is shared across navigation within the same domain, in order to improve the page load performance. The cache works in the same way as the existing in-memory cache for the stylesheets and the images. This can affect how the cached requests/responses are handled in DevTools, WebDriver, and WebExtensions APIs such as webRequest and declarativeNetRequest.
[Links (documentation, blog post, etc)]: None

Should I write some document, maybe?
For example the affected case of the WebExtensions APIs and suggested fix for the extensions?
