Summary: Add a client-driven tree prefetching implementation to the Rust manifest code. Unlike the existing prefetch implementation in Python, this one does all computation of which nodes to fetch on the client side using the BFS logic from BfsDiff. The trees are then bulk fetched layer-by-layer using EdenAPI. This initial version is fairly naive, and omits some obvious optimizations (such as performing fetches of multiple trees concurrently), but is sufficient to demonstrate HTTP tree prefetching in action.

lib
Any native code (C/C++/Rust) that Mercurial (either core or extensions)
depends on should go here. Python code, or native code that depends on
Python code (e.g. #include <Python.h>
or use cpython
) is disallowed.
As we start to convert more of Mercurial into Rust, and write new paths entrirely in native code, we'll want to limit our dependency on Python, which is why this barrier exists.
See also hgext/extlib/README.md
, mercurial/cext/README.mb
.
How do I choose between lib
and extlib
(and cext
)?
If your code is native and doesn't depend on Python (awesome!), it goes here.
Otherwise, put it in hgext/extlib
(if it's only used by extensions) or
mercurial/cext
(if it's used by extensions or core).
