bundlerepo: fix mismatches with repository and revlog classes Both pytype and PyCharm complained that `write()` and `_write()` in the bundlephasecache class aren't proper overrides- indeed they seem to be missing an argument that the base class has. PyCharm and pytype also complained that the `revlog.revlog` class doesn't have a `_chunk()` method. That looks like it was moved from revlog to `_InnerRevlog` back in e8ad6d8de8b8, and wasn't caught because this module wasn't type checked. However, I couldn't figure out a syntax with `revlog.revlog._inner._chunk(self, rev)`, as it complained about passing too many args. `bundlerevlog._rawtext()` uses this `super(...)` style to call the super class, so hopefully that works, even with the wonky dynamic subclassing. The revlog class needed the `_InnerRevlog` field typed because it isn't set in the constructor. Finally, the vfs type hints look broken. This initially failed with: File "/mnt/c/Users/Matt/hg/mercurial/bundlerepo.py", line 65, in __init__: Function readonlyvfs.__init__ was called with the wrong arguments [wrong-arg-types] Expected: (self, vfs: mercurial.vfs.vfs) Actually passed: (self, vfs: Callable) Called from (traceback): line 232, in dirlog line 214, in __init__ I don't see a raw Callable, but I tried changing some of the vfs args to be typed as `vfsmod.abstractvfs`, but that class doesn't have `options`, so it failed elsewhere. `readonlyvfs` isn't a subclass of `vfs` (it's a subclass of `abstractvfs`), so I'm not sure how to handle that. It would be a shame to have to make a union of vfs subclasses (but not all of them have `options` either).
