match: resolve filesets in subrepos for commands given the '-S' argument This will work for any command that creates its matcher via scmutil.match(), but only the files command is tested here (both workingctx and basectx based tests). The previous behavior was to completely ignore the files in the subrepo, even though -S was given. My first attempt was to teach context.walk() to optionally recurse, but once that was in place and the complete file list was built up, the predicate test would fail with 'path in nested repo' when a file in a subrepo was accessed through the parent context. There are two slightly surprising behaviors with this functionality. First, any path provided inside the fileset isn't narrowed when it is passed to the subrepo. I dont see any clean way to do that in the matcher. Fortunately, the 'subrepo()' fileset is the only one to take a path. The second surprise is that status predicates are resolved against the subrepo, not the parent like 'hg status -S' is. I don't see any way to fix that either, given the path auditor error mentioned above.

subrepo: introduce getfileset() This will be used in the next patch to help matchers resolve filesets in subrepos. The default implementation returns an empty set (for git and svn).

phase: default to current revision if no rev is provided (issue4666)

treemanifest: add --dir option to debug{revlog,data,index} It should be possible to debug the submanifest revlogs without having to know where they are stored (in .hg/store/meta/), so let's add a --dir option for this purpose.

obsolete: sort obsmarkers during exchange Because bundle2 allows a more precise exchange of obsmarkers during pull, it sends them in a different order (previously unstable because of sets.) As a result, they are added to the repository in a different order. To stabilize the order and ensure tests are unchanged when moving from bundle1 to bundle2 we sort markers when exchanging them. In the long run, the obsstore will probably not use a linear storage.

test-discovery-legacy: disable bundle2 for legacy test We need to disable the "bundle2" capability to ensure we stay on legacy capability.

test-discovery: disable bundle2 for legacy test (issue4610) We need to disable the "bundle2" capability to ensure we stay on legacy capability.

revset: fix iteration over ordered addset composed of non-ordered operands Before this change, doing ordered iteration over an 'addset' object composed of operands without fastasc or fastdesc method could result in duplicated entries. This was the result of applying '_iterordered' on an unordered set. We fix it by ensuring we iterate over the set in a sorted order. Using the fast iterator when it exists on any operand. We kill the '_iterator' method in the process because it did not make a lot of sense independently. Thanks goes to Yuya Nishihara for reporting the issue and analysing the cause.

match: add match.ispartial() match.ispartial() will return the opposite of match.always() in core, but this function will be extensible by extensions to produce another result even if match.always() will be untouched. This will be useful for narrowhg, where ispartial() will return False even if the match won't always match. This would happen in the case where the only time the match function is False is when the path is outside of the narrow spec.

util: drop alias for collections.deque Now that util.deque is just an alias for collections.deque, let's just remove it.
