Clone and pull, over git protocol, only ask the server for objects referenced by any refs -- plus all objects those depend on. Which does not necessarily mean all commits, because references may be removed. If a branch (ie. ref in refs/heads) is removed or rewound (moved to point to commit that is not descendant of what it pointed to before), some commits may become dangling. Clone and pull won't know such commits exist and therefore won't be able to ask server to provide them. > However, I have been unsuccessful in my attempts to use this identifier > to clone or checkout the associated source tree.

I bet that if you do 'git lost-found' here, it will find something and this commit will be among the finds, or predecessor of one of them. > /replication_dir $ git clone git://www.denx.de/git/u-boot.git > u-boot-mpc83xx > Blah blah blah.. > 100% (4378/4378) done > /replication_dir/u-boot-mpc83xx/ $ git checkout > 5b1313fb2758ffce8b624457f777d8cc6709608d > error: pathspec '5b1313fb2758ffce8b624457f777d8cc6709608d' did not match > any. It seems that git pull only accepts refs as arguments. So you'll have to create a branch at that commit in the origin to get it over to destination. -- Jan 'Bulb' Hudec <bulb@xxxxxx>
