Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Rest rate limiting code first commit. It is a bit rough and turned off by default. The current code is lossy. If client connections are fast enough, the rate limiting code doesn't count every connection. So the client can get more connections than configured if they are fast enough. 5-20% of the connections are not recorded.
