From a8c9bef4e0b87e596f37ec238991b447c739dee9 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 5 Oct 2009 15:35:16 -0400 Subject: [PATCH] pull: improve advice for unconfigured error case There are several reasons a git-pull invocation might not have anything marked for merge: 1. We're not on a branch, so there is no branch configuration. 2. We're on a branch, but there is no configuration for this branch. 3. We fetched from the configured remote, but the configured branch to merge didn't get fetched (either it doesn't exist, or wasn't part of the fetch refspec). 4. We fetched from the non-default remote, but didn't specify a branch to merge. We can't use the configured one because it applies to the default remote. 5. We fetched from a specified remote, and a refspec was given, but it ended up not fetching anything (this is actually hard to do; if the refspec points to a remote branch and it doesn't exist, then fetch will fail and we never make it to this code path. But if you provide a wildcard refspec like refs/bogus/*:refs/remotes/origin/* then you can see this failure). We have handled (1) and (2) for some time. Recently, commit a6dbf88 added code to handle case (3). This patch handles cases (4) and (5), which previously just fell under other cases, producing a confusing message. While we're at it, let's rewrap the text for case (3), which looks terribly ugly as it is.
