  "message": "cmd/go/internal/modfetch: do not short-circuit canonical versions\n\nSince at least CL 121857, the conversion logic in\n(*modfetch).codeRepo.Stat has had a short-circuit to use the version\nrequested by the caller if it successfully resolves and is already\ncanonical.\n\nHowever, we should not use that version if it refers to a branch\ninstead of a tag, because branches (unlike tags) usually do not refer\nto a single, stable release: a branch named \"v1.0.0\" may be for the\ndevelopment of the v1.0.0 release, or for the development of patches\nbased on v1.0.0, but only one commit (perhaps at the end of that\nbranch — but possibly not even written yet!) can be that specific\nversion.\n\nWe already have some logic to prefer tags that are semver-equivalent\nto the version requested by the caller. That more general case\nsuffices for exact equality too — so we can eliminate the\nspecial-case, fixing the bug and (happily!) also somewhat simplifying\nthe code.\n\nFixes #35671\nUpdates #41512\n\nChange-Id: I2fd290190b8a99a580deec7e26d15659b58a50b0\nReviewed-on: https://go-review.googlesource.com/c/go/+/378400\nTrust: Bryan Mills \u003cbcmills@google.com\u003e\nRun-TryBot: Bryan Mills \u003cbcmills@google.com\u003e\nReviewed-by: Russ Cox \u003crsc@golang.org\u003e\nTryBot-Result: Gopher Robot \u003cgobot@golang.org\u003e\n",
