1665523 - Runnable jobs not showing when using test path filtering

Status: NEW

(Tree Management :: Treeherder: Frontend, defect)

Description

[Cosmin Sabou [:CosminS]]

Runnable jobs are not shown on a push that a test didn't initially ran on.
Steps to repro:

1. open a TH push with all jobs showing, eg: https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=59fd9216fd8121d332d4b99da79c9b59bd1e42d5
2. add a test path filter, eg: browser/components/newtab/test/browser/
3. click the add new jobs, no runnable jobs are showing
4. remove the test path filter and all the runnable jobs are showing

This does not happen on a push that scheduled that test initially, for eg the push right below https://tinyurl.com/yy9686y9
It would come in handy for the sheriffs to be able to trigger jobs that contain a specific test in order to better track failures on tree when necessary.

This is likely because we fetch the manifests_by_task.gz file. I am fairly sure this only has the initial-run tasks/manifests. So we'd need to expand the coverage of this filtering to include a complete list. I don't know off the top of my head where such a list resides. But there probably IS one in Taskcluster somewhere.
