Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
wireproto: support for pullbundles Pullbundles are similar to clonebundles, but served as normal inline bundle streams. They are almost transparent to the client -- the only visible effect is that the client might get less changes than what it asked for, i.e. not all requested head revisions are provided. The client announces support for the necessary retries with the partial-pull capability. After receiving a partial bundle, it updates the set of revisions shared with the server and drops all now-known heads from the request list. It will then rerun getbundle until no changes are received or all remote heads are present. Extend badserverext to support per-socket limit, i.e. don't assume that the same limits should be applied to all sockets. Differential Revision: https://phab.mercurial-scm.org/D1856
