Fixes WORKER-Y7P. The issue was that: ReportSession QuerySet lacks select_related, causing N+1 queries for related objects and Testruns during iteration.

  • Added select_related("report__commit__repository") to the get_relevant_uploads query to eagerly load the related repository object, reducing N+1 queries.
  • Converted the result of get_relevant_uploads to a list to ensure immediate evaluation of the queryset.

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. In 2022 this entity acquired Codecov and as result Sentry is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.


Note

Low Risk
Low risk performance change limited to query evaluation and eager-loading; behavior should be unchanged aside from reduced DB queries.

Overview
Reduces N+1 database queries during flake processing by eager-loading report__commit__repository in get_relevant_uploads.

Forces immediate evaluation of the uploads queryset in process_flakes_for_commit by converting it to a list, avoiding repeated lazy DB hits during logging/iteration.
