context.status: call _dirstatestatus() from within _buildstatus() By making the call to _dirstatestatus() within _buildstatus(), it becomes clearer that it's called only for the workingctx.

context.status: move manifest caching trick to _buildstatus() In basectx._buildstatus(), we read the manifests for the two revisions being compared. For "caching reasons" unknown to me, it is better to read the earlier manifest first, which basectx._prestatus() takes care of. However, if the 'self' context is a committablectx and the 'other' context is the parent of the working directory (as in the very common case of plain "hg status"), there is no need to read any manifests at all -- all that's needed is the dirstate status. To avoid reading the manifests, _prestatus() is overridden in committablectx and avoids calling its super method, and _buildstatus() calls its super method only if the 'other' context is not the parent of the working directory. It seems easier to follow what's happening if we move the pre-fetching to _buildstatus() just before the place where the manifests are fetched. We just need to add an extra check that the revision is not None to handle the case that was previously handled by subclass overriding. That also makes it safe for committablectx._prestatus() to call its parent, although the latter now becomes empty, so we won't bother.

context.status: remove unused arguments from _matchstatus()

context.status: remove overriding in workingctx The workingctx method simply calls the super method. The only effect it has is that it uses a different default argument for the 'other' argument. The only in-tree caller is patch.diff, which always passes an argument to the method, so it should be safe to remove the overriding. Having the default argument depend on the type seems rather dangerous anyway.

synthrepo: when adding files, ensure new path is not a directory

synthrepo: synthesized dates must be positive, fit in 32-bit signed ints

discovery: test coverage for issue4438 / 86c35b7ae300 / 73cfaa348650 The randomness in the discovery protocol made this problem hard to reproduce. The test mocks random.sample to make sure we hit the problem every time. The set iteration order also made the output unstable ... but with the issue fixed, it is stable.

hgweb: fix a crash when using web.archivesubrepos A matcher is required when enabling the subrepo option on archival.archive(), because that calls match.narrowmatcher(), which accesses fields on the object. It's therefore probably a bad idea to default the matcher to None on archive(), but that's a fix for default.

tests: introduce a subrepository to test-archive.t This will be used in an upcoming patch to add coverage for web.archivesubrepos.

test-status-rev: add tests for plain dirstate and inter-revision status We have tests for the status across from '.^' to the working copy. It makes sense to have the similar tests for the inter-revision status between '.^' and '.' and for the dirstate status in the same place.
