Event TimelineComment Actions Ah Brilliant. Thanks for putting this up. We have been using this internally for some time to excellent effect. (For future reference, as it doesn't matter a lot here because it mostly new files, but uploading with lots of context (git diff -U99999) can help make the patches more readable, otherwise phabricator just show "Context not available") I read through it again now and still could not spot anything particularly wrong. LGTM! This revision is now accepted and ready to land.Nov 12 2020, 8:28 AM Comment Actions I know this has been tuned, and the structure looks good (I'm not checking any numbers here), so looks like a good addition to me! I will let Dave, who has looked more into it, LGTM this.
