git-lfs-filter

Clean and smudge filters, plus the long-running filter-process protocol, for Git LFS.

This crate implements the three things git invokes when a user runs git add or git checkout on an LFS-tracked file:

• clean — read raw file content on stdin, hash it, store the bytes locally, emit a pointer file on stdout. Used on git add.
• smudge — read a pointer on stdin, look up the bytes locally (or fetch them on demand), emit raw content on stdout. Used on git checkout.
• filter-process — the modern long-running variant of the same protocol. One subprocess handles many files in one session, speaking pkt-line framing.

Designed to be run as the body of git-lfs clean, git-lfs smudge, and git-lfs filter-process — the entry points wired up by git lfs install via filter.lfs.{clean,smudge,process} config.
