Summary: Depends on D19502. Ref T13151. See PHI719. An install ended up with an object with 111,000+ comments on it because someone wrote a script to treat it like a logfile. Although we seem to do mostly okay with this (locally, it only takes about 30s to index a similar object) we'll hit a wall somewhere (since we need to hold everything in memory), and it's hard to imagine a legitimate object with more than 1,000 comments. Just ignore comments past the first thousand. (Conpherence threads may legitimately have more than 1,000 comments, but go through a different indexer.) Test Plan: - Piped some comments into `maniphest.edit` in a loop to create a task with 100K comments. - Ran `bin/search index Txxx --force` to reindex it, with `--trace`. - Before: task indexed in about 30s. - After: script loaded comments with LIMIT 1000 and indexed in a couple seconds.
