From e9502c0a7fdb5649e3a3aece4e0d54ddb22983df Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 11 Jun 2018 01:53:57 -0400 Subject: [PATCH] fetch-pack: don't try to fetch peel values with --all When "fetch-pack --all" sees a tag-to-blob on the remote, it tries to fetch both the tag itself ("refs/tags/foo") and the peeled value that the remote advertises ("refs/tags/foo^{}"). Asking for the object pointed to by the latter can cause upload-pack to complain with "not our ref", since it does not mark the peeled objects with the OUR_REF (unless they were at the tip of some other ref). Arguably upload-pack _should_ be marking those peeled objects. But it never has in the past, since clients would generally just ask for the tag and expect to get the peeled value along with it. And that's how "git fetch" works, as well as older versions of "fetch-pack --all". The problem was introduced by 5f0fc64513 (fetch-pack: eliminate spurious error messages, 2012-09-09). Before then, the matching logic was something like: if (refname is ill-formed) do nothing else if (doing --all) always consider it matched else look through list of sought refs for a match That commit wanted to flip the order of the second two arms of that conditional. But we ended up with: if (refname is ill-formed) do nothing else look through list of sought refs for a match if (--all and no match so far) always consider it matched That means tha an ill-formed ref will trigger the --all conditional block, even though we should just be ignoring it. We can fix that by having a single "else" with all of the well-formed logic, that checks the sought refs and "--all" in the correct order.
