Summary:
This unused feature allowed a sub-process to inherit an hg repo wlock from the parent process. It was apparently intended for merge drivers, but nothing was using it.
I want to move some locking logic into rust, and this stuff was complicating things.
Note that this functionality was also removed upstream in https://phab.mercurial-scm.org/D9053.

Summary: This project has custom stubs that contain type errors. We'll need to fix them so the switch to new Pyre backend won't create any regressions.

Summary:
The EdenFS import helper's `_fetch_tree_impl` method works by either calling `repo._prefetchtrees` or `repo.prefetchtrees`, both of which are methods from `treemanifest` extension's `treerepository` class. Unfortunately, these methods are lower-level than their names would suggest, and will always perform gettreepack style fetching (see [1]).
If HTTP fetching is enabled, this means that EdenFS will always query EdenAPI's `/complete_trees` endpoint instead of `/trees`, which is needlessly expensive given that EdenFS just wants the exact set of trees specified. As a somewhat hacky workaround, this diff just checks whether HTTP fetching is enabled, and if so, directly calls the appropriate HTTP fetch method.
This solution isn't ideal; it would be better for the import helper to request the trees from Mercurial's `remotetreestore` instead of via methods from `treerepository`. Unfortunately, with the current structure of Mercurial's storage layer, the `remotetreestore` isn't readily accessible because it gets passed into the Rust API's storage hierarchy upon construction.
---
[1]: The various `*prefetchtrees` methods are usually called from Mercurial's `remotetreestore`, which is where the choice of tree fetching strategy is made (i.e., designated nodes vs gettreepack). The `remotetreestore` then calls `*prefetchtrees` for gettreepack-style fetching, or `*getdesignatednodes` for on-demand fetching. As such, a call to `*prefetchtrees` generally implies gettreepack-style fetching.

Summary:
In the past we hide the revlog headrevs API with the idea that calculating
heads in the DAG is not going to scale, and heads should be based on references
(remotenames, visible heads). Practically calculating heads in the DAG based
on segmented changelog is not going to be painfully slow so we probably can
afford it.
Therefore let's just re-expose the DAG-based heads API as rawheads. The only
user of it is in dagutil.py.
This will be used in the next diff where streamclone first gets the revlog
changelog copied without remote bookmarks. Then it needs to do a pull
which requires the heads information.

Summary:
The "repo" type is a bit hard to type since it might be wrapped by extensions,
and the decorators like "unfilteredmethod" are too hard for type checkers.
Provide a stub for it so typecheck can work. The stub was generated by `pytype`,
I made a small change to `close` to make pyre happy.

Summary:
The issues were found by pyre with some type stubs generated via pytype:
python36 -m pytype edenscm --no-report-errors -j 30
I didn't include the pytype generated stubs because most of them are `Any`.
I'm trying to see if we can get something cleaner.

Summary:
Add a partial stub so pyre stops complaining about "bindings" being unknown.
Pyre's "search_path" was adjusted to read the new "pystubs" directory.
