Re: [PATCH v4 0/1] receive-pack: optionally deny case clone refs

David,

One possible solution can be to use the external database daemon I am
working of for ref transactions.
Since this makes all refs be stored in a dedicated database instead of
the filesystem you no longer are dependent on file system semantics.

While not in the official git trees yet I would appreciate any testing
and comments you may have it you want to test it.
https://github.com/rsahlberg/git/tree/backend-struct-db-2

Not for production use but seeing if it does build and works on your
platforms would be great.


    refsd-tdb: example refs database daemon

    refsd-tdb.c is a simple reference implementation of a refs daemon.
    This will eventually be hosted in a separate project but can live in this
    branch for now.

    Compile with :
    gcc refsd-tdb.c -o refsd-tdb -l tdb

    Run with:
    ./refsd-tdb /tmp/refsd.socket /tmp /tmp/refsd.log

    Once the refs daemon is running you can start using it with newly
    created git repositories by specifying the --db-socket and --db-repo-name
    arguments to git clone/init-db :

    git clone --db-repo-name=ROCKy --db-socket=/tmp/refsd.socket <some repo> .

    This refs daemon is an example. It should be relatively straightforward
    to modify it to attach to any other kind of data store.

regards
