verify: replace _validpath() by matcher...
verify: replace _validpath() by matcher The verifier calls out to _validpath() to check if it should verify that path and the narrowhg extension overrides _validpath() to tell the verifier to skip that path. In treemanifest repos, the verifier calls the same method to check if it should visit a directory. However, the decision to visit a directory is different from the condition that it's a matching path, and narrowhg was working around it by returning True from its _validpath() override if *either* was true. Similar to how one can do "hg files -I foo/bar/ -X foo/" (making the include pointless), narrowhg can be configured to track the same paths. In that case match("foo/bar/baz") would be false, but match.visitdir("foo/bar/baz") turns out to be true, causing verify to fail. This may seem like a bug in visitdir(), but it's explicitly documented to be undefined for subdirectories of excluded directories. When using treemanifests, the walk would not descend into foo/, so verification would pass. However, when using flat manifests, there is no recursive directory walk and the file path "foo/bar/baz" would be passed to _validpath() without "foo/" (actually without the slash) being passed first. As explained above, _validpath() would return true for the file path and "hg verify" would fail. Replacing the _validpath() method by a matcher seems like the obvious fix. Narrowhg can then pass in its own matcher and not have to conflate the two matching functions (for dirs and files). I think it also makes the code clearer.
