  "message": "ChangeControl: Optimize creation by not re-reading changes\n\nThere are two different controlFor() methods that accept change id\nand change. It seems that all callers have change instance available\nso there is no need to re-read the changes from the database.\n\nThis fixes flaky query tests, see this thread for more details [1].\n\nTEST PLAN:\n\nTo reproduce you need heavy load on your machine. For example start\nLibreOffice\u0027s unit tests parallel to Gerrit\u0027s query tests:\n\n  $ libreoffice\u003e make check\n  $ gerrit\u003e buck test --no-results-cache //gerrit-server:query_tests\n\nRepeat the last command multiple times. Without this change I observed\n2-4 failures from 10 runs.\n\n[1] https://groups.google.com/d/topic/repo-discuss/9wGKjTaVG7k\n\nChange-Id: Ia95458e86b214b12186ca60ccad46d586e13a01c",
