描述

What's the problem this feature will solve?

pip install git+...@foo-branch clones the whole repository and then checks out foo-branch. This process takes some time if the repository has a long history or many branches.

Describe the solution you'd like

I'd like to leverage git clone parameters to make the whole thing faster when a specific branch is requested. In particular, I'd use `the following:

  • --branch foo-branch
  • --depth 1

Alternative Solutions

The current solution works fine, but is slow in some specific situations.

研究方向
Investigate pip's source code for VCS clone operations, likely in src/pip/ internal/vcs/git.py. Look at how the clone command is constructed and where branch and depth options can be added. Review any previous discussions in the comments of this issue for potential pitfalls.
