While the impact of this bug is minimal, and git itself is not
affected, it can affect external tools that want to read the
.git/config file, expecting unique section names.
To reproduce:
Given the following example .git/config file (I am leaving out the
[core] section for brevity):
[remote "origin"]
url = g...@github.com:Fryguy/example.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
Running `git remote rm origin` will result in the following contents:
[branch "master"]
Running `git remote add origin g...@github.com:Fryguy/example.git` will
result in the following contents:
[branch "master"]
[remote "origin"]
url = g...@github.com:Fryguy/example.git
fetch = +refs/heads/*:refs/remotes/origin/*
And finally, running `git fetch origin; git branch -u origin/master`
will result in the following contents:
[branch "master"]
[remote "origin"]
url = g...@github.com:Fryguy/example.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
at which point you can see the duplicate sections (even though one is
empty). Also note that if you do the steps again, you will be left
with 3 sections, 2 of which are empty. This process can be repeated
over and over.
Thanks,
Jason
