@ianlancetaylor requested issue #71261 to be considered for backport to the next 1.23 minor release.

@gopherbot Please open backport issues

This test is failing with older versions of Go, presumably because of a newer versions of git. We should backport the fix to supported versions, so that people using older Go versions don't complain when the update to a newer version of git.

[release-branch.go1.23] cmd/go/internal/modfetch: do not trust server…
ab44565 
… to send all tags in shallow fetch

Newer git versions (at least git 2.47.1) do not send all the matching tags
for a shallow fetch of a specific hash anymore. The go command assumes
that git servers do this. Since that assumption is broken, use the local
copy of the remote refs list to augment the tags sent by the server.
This makes the cmd/go/internal/modfetch tests pass again with newer git.

Fixes #71263
