prepush: print short hash of first new head in abort message and don't mention the branch if it's the default branch. OLD: $ hg push ../a pushing to ../a searching for changes abort: push creates new remote heads on branch 'default'! (you should pull and merge or use push -f to force) NEW: $ hg push ../a pushing to ../a searching for changes abort: push creates new remote head 1e108cc5548c! (you should pull and merge or use push -f to force) This helps to identify which local head is causing troubles. See also change 91cb08a9e7fb.

prepush: eliminate 'if branch' branch is always set anyway No change in program behavior.

revlog: bail out earlier in group when we have no chunks

localrepo: simplify file bundling code and fix progress bug Progress for files was off by one, and the code was rather hackish.

localrepo: use list comprehension instead of generators The lists in question are iterated and kept in memory further down the code path anyway, and this simplifies things.

localrepo: add total to changeset progress in bundle/push

statichttprepo: use in-place difference for shorter line

workingctx: eliminate remove function Inlining it into it's last remaining call place in cmdutil.copy. Note that cmdutil.copy is called with the wlock already held, so no additional locking is needed to call util.unlinkpath. We do not need to wrap the util.unlinkpath call into a try block, because at that point we already know whether abssrc exists or not -- thanks to the preceding util.copyfile call. Adding a new local 'srcexists' in cmdutil.copy for that purpose.

test-copy2: add case for moving a missing file

color: check if ui is already a subclass of colorui before wrapping it since it's possible to reuse the ui object (see 80c599eee3f3) between dispatch calls, the ui might have been wrapped already. we could probably move this test up a bit but leaving it here allows updates to take effect by extstyles() and configstyles().
