I ran mozregression-gui. 2017-12-14 Last Good day 2017-12-15 First Bad day The tail of the Log has: > Bug 1416991 - Fix perspective indexing in partial DL builds - r=mattwoodrow > > Perspective item indices (used to produce unique per-frame keys) were generated > by incrementing a counter in the builder when building a perspective display > item. This caused problems with retained display lists, because an unmodified > perspective could be skipped during a partial build, causing other perspectives > to be incorrectly numbered and then incorrectly merged with the previous > retained display list. > > To fix this, we need to always increment the counter if there is likely to be > a perspective, before that item may be skipped. > > MozReview-Commit-ID: Edn7lUOLuPw > > 2018-08-18T00:28:43: DEBUG : Did not find a branch, checking all integration branches > 2018-08-18T00:28:43: INFO : The bisection is done. > 2018-08-18T00:28:43: INFO : Stopped Bisection informations window contained: > app_name: firefox > build_date: 2017-12-15 00:20:49.556000 > build_file: C:\Users\Mark\.mozilla\mozregression\persist\d5da77c14481--autoland--target.zip > build_type: inbound > build_url: https://queue.taskcluster.net/v1/task/BsUsZ8f1SF-TNQyys9YM_A/runs/0/artifacts/public%2Fbuild%2Ftarget.zip > changeset: d5da77c1448183b938e263421b7ea4f679b8a944 > pushlog_url: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=89f8f948c2d1a582b82384543f24e9a69a051617&tochange=d5da77c1448183b938e263421b7ea4f679b8a944 > repo_name: autoland > repo_url: https://hg.mozilla.org/integration/autoland > task_id: BsUsZ8f1SF-TNQyys9YM_A Uploading full regression log as mozregressions_Bug_1484412.txt
