From: Harald Nordgren via GitGitGadget Date: Fri, 02 Oct 2026 07:13:14 GMT Subject: [PATCH v5 0/4] fetch: avoid fetching every branch of a new remote in a shallow repo Message-ID: In-Reply-To: Avoid fetching every branch of a new remote in a shallow repo. Changes in v5: * Renumber test file from t5585 to t5586. Changes in v4: * Removed the automatic default-branch fetch. A fresh remote fetches nothing until you track a branch explicitly. * Fixed fetch report showing "new ref HEAD" instead of "new branch " * Reworded remote..refmap docs and commit message. Changes in v3: * Replace the special ":"/"+:" fetch refspec with remote..refmap, reusing git's existing --refmap mechanism instead of inventing new refspec syntax. * Split the change into 4 commits. Changes in v2: * Replaced the opt-in fetch.shallow config entirely with a new special fetch refspec (+:) that git remote add now defaults new remotes to in a shallow repository. The new refspec fetches whichever branches any local branch tracks at that remote, plus the remote's default branch.
