Subject: [PATCH] import: convert init.defaultBranch to fully qualified ref
Date: Wed, 07 Apr 2021 19:05:24 -0400	[thread overview]
Message-ID: <87ft01puff.fsf@kyleam.com> (raw)

Recently I've tried lei on another machine and scratched my head for a
bit about why the local storage seemed to be in a corrupt state.  With
`lei q', no mail was getting imported, and I saw a good number of
"fatal: not a git repository: ..." messages.

It turns out that HEAD's content is invalid, and that's happening
because PublicInbox::Import mishandles init.defaultBranch, which I've
configured on that machine to suppress the associated `git init' hint.

Subject: [PATCH] import: convert init.defaultBranch to fully qualified ref

init.defaultBranch expects a branch name, not a fully qualified ref.
git-init prepends "refs/heads/" automatically and unconditionally.

PublicInbox::Import::default_branch, however, incorrectly passes on
the init.defaultBranch value as is, leading to it being used in spots
where a fully qualified ref is required.  For example, with an
init.defaultBranch value of "master", public-inbox-index for a v2
repository would lead to an all.git repository where HEAD's content is
"ref: master" instead of "ref: refs/heads/master".

Prepend "refs/heads/" to the incoming init.defaultBranch value.

Fixes: 7c2f36de2fb49dd7 (import: respect init.defaultBranch)
