I'm creating this PR for a fourth time (see #163, #171, and #178 for earlier versions). This version is tracking my progress to create something that can be sent as an RFC upstream, but also can be used to start the sparse feature branch. This is based on v2.23.0. Note: I currently have conflicts with the virtual filesystem feature, and I'll resolve those with a merge commit when I'm ready. I'm just creating this for tracking progress at the moment, but can also be a place for early feedback. * git sparse-checkout disable to disable the sparse-checkout feature and return to a full checkout. * git sparse-checkout init --cone, to initialize in cone mode. * git sparse-checkout add when core.sparseCheckout=cone. This includes performance improvements with the hashset-based matching algorithm, but I'll leave further enhancements as smaller steps on top. Here are a few things I want to try: Track the maximum depth of a prefix pattern, so we know to not run hashes for deeper paths. Use the "known exclude" bit in cone mode to stop hashing paths we know will not be included. Use the "known include" bit in cone mode to stop hashing paths we know will be included. This is more difficult than "known exclude" because we need to distinguish directories from files when doing path matches so we don't give a directory a "known include" when it isn't a recursive pattern match.

This is the "version zero" of the sparse-checkout builtin. This version is preliminary, and will eventually be replaced by something that can be sent upstream. This is being merged to the feature branch to facilitate moving forward with sparse-mode work in the [redacted] repo.
git sparse-checkout initinitializes thecore.sparseCheckoutconfig variable tocone, which restricts the pattern set to our new model.git sparse-checkout addreads a list of folders fromstdinand creates the proper patterns in the sparse-checkout file, then runsgit read-tree -mu HEADto update the index and populate the working directory.git sparse-checkout listshows the patterns in the sparse-checkout file.
