Hi,
I might start working on implementing reftable in Git soon.
During the last Git Merge conference last March Stefan talked about
reftable. In Alex Vandiver's notes [1] it is asked that people
announce it on the list when they start working on it, and it appears
that there is a reference implementation in JGit.
Thanks for starting on this! In addition to the performance gains, this
will help a lot of users with case-insensitive file systems from getting
case-errors on refnames.
Looking it up, there is indeed some documentation [2], code [3], tests
[4] and other related stuff [5] in the JGit repo. It looks like the
JGit repo and the reftable code there are licensed under the Eclipse
Distribution License - v 1.0 [7] which is very similar to the 3-Clause
BSD License also called Modified BSD License which is GPL compatible
according to gnu.org [9]. So from a quick look it appears that I
should be able to port the JGit to Git if I just keep the copyright
and license header comments in all the related files.
So I think the most straightforward and compatible way to do it would
be to port the JGit implementation.
Thanks in advance for any suggestion or comment about this.
Reftable was first described by Shawn and then discussed last July on
the list [6].
The hope is that such a direct port should be possible, but someone else
should comment on the porting process.
This is also something that could be created independently based on the
documentation you mention. I was planning to attempt that during a
hackathon in July, but I'm happy you are able to start earlier (and that
you are announcing your intentions). I would be happy to review your
patch series, so please keep me posted.
Thanks,
