cmdserver: write the hello message as one chunk on the 'o' channel This is a guaranteed by the protocol: clients know they need to read one chunk off of the 'o' channel and treat that as the hello message. They should ignore fields they don't recognize so they stay compatible with new versions of the server in case we decide to add something.

revset and fileset: fix typos in parser error messages

fileset: use ParseError pos field correctly The pos field is intended to describe the position of the error - it should not be used for other potentially interesting information.

revert: be more explicit that changes are lost BEFORE: $ hg revert abort: no files or directories specified (use --all to revert all files) AFTER: $ hg revert abort: no files or directories specified (use --all to discard all changes)

dispatch: do not close the request repo Closing here means we've closed the repo passed to us in the request, which is not our responsibility. This is essential for bundlerepo, and possibly other localrepository subclasses who do something in their close().

hook: write hook output to ui fout descriptor output on stderr will also be written to ui.fout, unless sys.__stdout__ is passed in (see util.system), thus not changing previous behavior. This fixes a bug where hooks run through the command server would mess up with the command protocol, sending non-channeled data to the client.
