v5: git: submodule, error on remote without URLs#2078
Merged
Conversation
`defaultRemote`, introduced on this branch in a675ed4, returns a `*RemoteConfig` that `submodule.Repository()` then dereferences as `base.URLs[0]` to join a relative submodule URL. `RemoteConfig.Validate()` rejects an empty `URLs` slice on `SetConfig`, but a config that bypasses validation — for example a hand-edited `[remote "origin"]` section with no `url =` entry loaded from disk — could still produce a remote with no URLs and panic the caller with `index out of range [0] with length 0`. Promote the invariant into `lookupRemote` and route the single-remote branch through it as well, so any code path that asks `defaultRemote` for the resolution base gets a usable remote or a clear `remote %q has no configured URL` error. Backport of go-git#2076. Assisted-by: Claude Opus 4.7 Signed-off-by: Hidde Beydals <hidde@hhh.computer>
