From e0c77024cbe84c634cc9f360c5c083a68cbf248b Mon Sep 17 00:00:00 2001 From: Essien Ita Essien <34972+essiene@users.noreply.github.com> Date: Mon, 4 Nov 2024 20:19:26 +0000 Subject: [PATCH] cli: Refactor out `get_fetch_remotes` into git_util.rs Similarly to `git_fetch`, this will be used in `jj git sync`, so moving this out to maintain the same behaviour across `fetch` command and `sync`. * Refactor out `get_fetch_remotes` to `git_util.rs`. * inline the different `get_*_remote*` functions into `get_fetch_remotes`; The resulting function is still small enough to be easily readable. * Move `get_single_remote` into `git_util.rs` and update call sites. * Use common FetchArgs to pass arguments both to `get_fetch_remotes` and `git_fetch` * Update use references All tests still pass.
