Xavier Deguillard 73aed5c3d2 revisionstore: do not attempt repacking one packfile
Summary:
Repacking one packfile will yield the same packfile, so we can save some IO by
not trying to repack.

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).
