From: Jiang Xin <zhiyou.jx@xxxxxxxxxxxxxxx> This topic introduces a new hook named "proc-receive" for "receive-pack". We can use this hook to implement a Gerrit-like centralized workflow. ## Changes since v16 1. Fixes test helper for proc-receive which is not compatible with sha256. Run `setup_git_directory_gently()` in `t/helper/test-proc-receive.c`, so that `the_repository` variable is initialized with proper hash_algo.
