From 3b5fb32da836f5aead1cef319bc3e0a9b975ea35 Mon Sep 17 00:00:00 2001 From: Nasser Grainawi Date: Tue, 3 Mar 2026 15:40:44 -0800 Subject: submodule: fetch missing objects from default remote When be76c21282 (fetch: ensure submodule objects fetched, 2018-12-06) added support for fetching a missing submodule object by id, it hardcoded the remote name as "origin" and deferred anything more complicated for a later patch. Implement the NEEDSWORK item to remove the hardcoded assumption by adding and using a submodule helper subcmd 'get-default-remote'. Fixing this lets 'git fetch --recurse-submodules' succeed when the fetched commit(s) in the superproject trigger a submodule fetch, and that submodule's default remote name is not "origin". Add non-"origin" remote tests to t5526-fetch-submodules.sh and t5572-pull-submodule.sh demonstrating this works as expected and add dedicated tests for get-default-remote.
