Hi At Mozilla we use a mercurial repository, however many developers are using a git repository; we maintain two git mirrors, mozilla-unified accessed via the cinnabar plugin and a geck-dev native git mirror. Our repositories contain a .git-blame-ignore-revs that is used for both repositories. https://searchfox.org/mozilla-central/source/.git-blame-ignore-revs That git was ignoring invalid entries (for the currently in use repo) is a requirement for our use. Following the merge of 610e2b9240 jc/blame-ignore-fix later we have lost the ability to run git blame on any of our files. Could we get that change reversed? If it ain't broken, don't fix it as they say. Thank you Jean-Yves Avenard
