nodemap: fix some comment formatting Black seems unhappy about it. Differential Revision: https://phab.mercurial-scm.org/D10865

revlogv2: fix `hg verify` with revlog v2 We added a bunch of new files but we never teached some internal about it. This is now fixed. Differential Revision: https://phab.mercurial-scm.org/D10858

revlogv2: also test that local clone works This is now the case so lets add a test. Differential Revision: https://phab.mercurial-scm.org/D10857

clone: also report the bookmark file as copied This is a small UI adjustement, but this is easy enough to do. Differential Revision: https://phab.mercurial-scm.org/D10856

clone: reuse the stream clone logic for local clone Streaming clone and local (non `--pull`) clone do mostly the same thing, however they were using different logic to do so. This means the logic frequently went out of sync and that new case had to be dealt with twice. This is fragile and anoying. So we replace this with a re-use of the logic we use for streaming clone. I can see various test changes: - a more precise progress output, - armless fncache loading during clone, - fncache is no longer hardlinked (since we write it by hand). I am not reinstalling the `reposimplestore` specific output, as far as I understand this variant have been broken for years. Differential Revision: https://phab.mercurial-scm.org/D10855

copyfiles: add a way to relax the file system checking for hardlink This is critical for transaction file, less for hardlink/copy clone as we are about to do. Since `pure` build does not have a `getfstype` implementation this would disable hardlink clone for all pure build. So we add a parameter to control that extra check.

copyfile: add a option callback for failed hardlinking Local clone, adjust its UI depending on the success of using hardlinking, so we add a small callback making it possible for `copyfile` to signal if the requested hardlinking failed. Differential Revision: https://phab.mercurial-scm.org/D10853

streamingclone: extract the scanning part from the generation part We will reuse the scanning part for local clone, so we need it in a dedicated function. Differential Revision: https://phab.mercurial-scm.org/D10852

vfs: add a `register_file` method on the vfs class This is used by the fncache vfs to register new file. Until now, `fncache` have been doing this "automatically" by monitoring write pattern. However this is fragile and when we copy files in place by other means, we need something more robuts. So we add an explicit method to do so. Differential Revision: https://phab.mercurial-scm.org/D10851

clone: use "official" API to create local clone destination This make sure we have a properly created, fully functional repository early. This will be useful to simply the hardlink/copy phases of the local clone to make it share more of its logic with the similar "stream" cloning. This has a minor impact of the test and the resulting repository has is better initialized (eg: the `wcache` directory is pre-created.) Differential Revision: https://phab.mercurial-scm.org/D10850
