fastannotate: pconvert paths from the server for Windows I'm guessing that the right thing to do here is to convert the paths on the server, but I know this is a WIP, and I don't know where that needs to happen. I'm just trying to eliminate the malicious path warnings in the tests.

test-fastannotate: close fd before unlinking to keep Windows happy

test-fastannotate: fix trivial output differences on Windows

fastannotate: make the default value for `fastannotate.useflock` dynamic fcntl.flock isn't available on Windows.

narrow: add a --narrowspec flag to clone command This patch adds a --narrowspec flag to `hg clone` command in narrow extension which can be used to read a file and parse narrowspecs from it and use it while cloning a repository. The --narrowspec flag assumes that the user wanted to narrow the clone. Tests are added both for ellipsis and non-ellipsis mode. Differential Revision: https://phab.mercurial-scm.org/D4156

manifest: use rev() instead of nodemap.__contains__ nodemap is an implementation detail of revlogs and isn't appropriate to expose on the manifest storage API. While revlogs don't have a __contains__, they do have lookup() for resolving a value to a node. And this calls rev(), whose API is documented to raise LookupError if a node doesn't exist. And the parameters to LookupError are identical to what was being raised here. So this change should be backwards compatible. Differential Revision: https://phab.mercurial-scm.org/D4279

manifest: rename manifestlog._treeinmem to ._treemanifests Not sure what "inmem" was supposed to indicate. This object is an interface to manifest data on disk as well as "in memory" (assuming that's what "inmem" means). Differential Revision: https://phab.mercurial-scm.org/D4278

manifest: add getstorage() to manifestlog and use it globally It is a common pattern to obtain a directory manifest storage instance (a manifestrevlog) by going through manifestlog._revlog.dirlog(). Why access to storage and caching of other manifests is done through manifestrevlog instead of manifestlog, I don't know. This commit establishes a getstorage(tree) API on manifestlog and imanifestlog that provides a public API for accessing manifest storage. All consumers previously using private attributes have been updated to use this new method. .. api:: manifestlog now has a getstorage(tree) method It should be used for obtaining an object representing the manifest's storage implementation. Accessing manifestlog._revlog should be avoided. Differential Revision: https://phab.mercurial-scm.org/D4277

manifest: rename dir argument and attribute to tree dir shadows a built-in. We use it throughout the manifest code, which is unfortunate. This commit updates just manifestrevlog to be more well behaved. .. api:: renamed manifest.manifestrevlog.__init__ dir argument to tree Differential Revision: https://phab.mercurial-scm.org/D4276

manifest: set appropriate cache entry when clearing _dirlogcache() manifestrevlog applies to any manifest, not just the root manifest. Resetting the cache and populating its root entry with self is not correct when the instance does not refer to the root manifest. This has no test fallout. So I'm guessing we only ever call clearcaches() on the root manifest. Or we have no test coverage that are impacted by a bad cache on a non-root manifestrevlog.
