From 8d5747c8fdc3d952696505562e7804e8e5fa0ab2 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/6] [release-branch.go1.17] cmd/go/internal/modfetch: do not
short-circuit canonical versions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since at least CL 121857, the conversion logic in
(*modfetch).codeRepo.Stat has had a short-circuit to use the version
requested by the caller if it successfully resolves and is already
canonical.
However, we should not use that version if it refers to a branch
instead of a tag, because branches (unlike tags) usually do not refer
to a single, stable release: a branch named "v1.0.0" may be for the
development of the v1.0.0 release, or for the development of patches
based on v1.0.0, but only one commit (perhaps at the end of that
branch — but possibly not even written yet!) can be that specific
version.
We already have some logic to prefer tags that are semver-equivalent
to the version requested by the caller. That more general case
suffices for exact equality too — so we can eliminate the
special-case, fixing the bug and (happily!) also somewhat simplifying
the code.
Updates #35671
Fixes #50687
Fixes CVE-2022-23773
