backout of d04ba50e104d: allow to qpop/push with a dirty working copy The new behavior was breaking existing tools that relied on a sequence such as this: 1) start with a dirty working copy 2) qimport some patch 3) try to qpush it 4) old behavior would fail at this point due to outstanding changes. (new behavior would only fail if the outstanding changes and the patches changes intersect) 5) innocent user qrefreshes, gets his local changes in the imported patch It's worth considering if we can move this behavior to -f in the future.

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)
