1670290 - ub18-test docker image sometimes gets build with no pre-created font-cache

Status: RESOLVED WONTFIX

(Firefox Build System :: Task Configuration, defect, P3)

Description

As noticed on bug 1651542 Firefox sometimes takes around 15s for the firs startup:

https://share.firefox.dev/3h5OAXB

Again this is related to the font cache which usually should be pre-generated when creating the docker image. But since bug 1626058 landed it sometimes fail, and as such starting Firefox for the first time will trigger the cache generation.

That means that most of our Linux jobs in CI based on ub180-test currently take 15s longer.

We already had this issue permanently before (see bug 1633101) but this time it's kinda unclear what triggers it.

Is there anyone from the build team who could have a look at this?

Is this still relevant?

Comment 2

Yes, it is. We still need the workaround in Puppeteer tests because there is no font cache and the first start of Firefox takes up to 15s.

Probably not a P1 bug

Given that we switch to Wayland (Ubuntu 22.04) workers and it should be fixed there I'm fine with marking this bug as wontfix. We were waiting that long so that I don't see that we need to still fix it.
