1851253 - known failure lines labeled as 'NEW'

Status: REOPENED

(Tree Management :: Treeherder: Frontend, defect)

Description

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

Code sheriff Narcis noticed more failure lines than usual are labeled as 'NEW', and at least some of them have been observed before.

E.g. this task from today has the line set as 'NEW' but it had already been observed yesterday.

good find. I strongly suspect this is a side effect of using the cache. about 14 hours ago we deployed treeherder, so the cache was probably reset. I need to find a way to make it a persistent cache.

I landed a fix to treeherder (on staging now) to use database backed cache instead of redis which is memory based cache. This will allow for persistent cache across restarts:

Backed out because the failure lines and their bug suggestions did not load at least for some task, e.g. mda:
