1662229 - Linux asan anti-tracking browser-chrome tests' task (bc16) often retried (crashing?)

Status: NEW

(Core :: Privacy: Anti-Tracking, defect, P5)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

The task which runs the browser-chrome tests in toolkit/components/antitracking/test/browser/browser.ini on Linux asan (AddressSanitizer) often gets automatically retried which means there was an internal issue. Sometimes even 6 runs fail:
https://treeherder.mozilla.org/#/jobs?repo=autoland&group_state=expanded&selectedTaskRun=XtP5za5MQzK8PP1ilc0CRA.5&searchStr=linux%2Casan%2Cbrowser-chrome%2Cbc16&fromchange=502ffd8d642152c923e482776332fe54dac7f896

bc15 which runs webextension tests also gets retried but succeeds and doesn't end with an exception after a sixth run (a successful run prevents further automatic ones).

Andrew, could this be a low memory situation in the workers and how could this be debugged?

we could skip these tests on linux/asan - a lot of individual tests are already skipped:

The leave-open keyword is there and there is no activity for 6 months.
:timhuang, maybe it's time to close this bug?

[Tim Huang[:timhuang]]

Ideally, I think we still want tests to be able to run in asan build. So, I tend to leave this open.

it has been almost 2 years since these tests were disabled and no action has taken place in this bug or related bugs to fix this- Fixing these tests seem like a P5, maybe we should close this bug.

Comment 13

[Tim Huang[:timhuang]]

A P5 is reasonable here. It would be good that anti-tracking tests can be run on asan build, but it's a low priority for us.
