update: do not use the term 'update' when mentioning reverting one file and give a more precise hint for how to revert such a file I'm using the term 'revision' instead of 'changeset' in this change to be consistent with the REV we use in the synopsis.

cmdserver: fix read-loop string concatenation

dispatch: check for None before closing repo We were trying to call close() if repo == None and req.repo != None. This can happen when running commands that don't take a repo.

revert: mention update in hint of abort when reverting to non-parent and explicitly warn about uncommitted changes Examples: BEFORE: $ hg par -q 7:e81a2efd53d4 $ hg revert -r 2 abort: no files or directories specified (use --all to discard all changes) AFTER: Clean working directory (revert can be easily undone, no edits to be lost): $ hg revert -r 2 abort: no files or directories specified (use --all to revert all files, or 'hg update 2' to update) Uncommitted changes (revert --all *does* discard edits and is pretty hard to undo or even impossible if --no-backup is specified): $ hg revert -r 2 abort: no files or directories specified (uncommitted changes, use --all to discard all changes, or 'hg update 2' to update)

update: clarify that update changes the parent revison

merge with stable

revset: fix aliases with 0 or more than 2 parameters The existing code seemed to have incorrect assumptions about how parameter lists are represented by the parser. Now the match and replace functions have been merged and simplified by using getlist().

match: fix bug caused by refactoring in cfc89398f710

revert: be more helpful on uncommitted merges BEFORE: $ hg revert abort: no files or directories specified (use --all to discard all changes) AFTER: $ hg revert abort: no files or directories specified (uncommitted merge, use --all to discard all changes, or 'hg update -C .' to abort the merge)

opener: add self._audit (issue2862)
