Subject: [PATCH v2] fast-import: tag may point to any object type
Date: Wed, 13 Jan 2010 15:35:32 +0300 [thread overview]
Message-ID: <20100113123532.GC10586@dpotapov.dyndns.org> (raw)
In-Reply-To: <20100111171454.GO32155@spearce.org>
If you tried to export the official git repository, and then to import it
back then git-fast-import would die complaining that "Mark :1 not a commit".
Accordingly to a generated crash file, Mark 1 is not a commit but a blob,
which is pointed by junio-gpg-pub tag. Because git-tag allows to create such
tags, git-fast-import should import them.

Thank you for guideliness. I do not understand this code well.
I hope I got it right this time.
