However, there was one very long and productive discussion about the design of svn-fe. We can now prove that the design of svn-fe is most efficient, and that any other dumpfile importer will do worse than svn-fe. I'll put this proof down in another email, and use this one for just a status update. We have also determined that some some extensions to git-fast-import will significantly reduce the complexity of svn-fe. Here are the current list of tasks along with their status: 1. The svnclient_ra. I have stopped working on a stopgap implementation of svnclient_ra that dumps full text/ props; to do this, it needs to interrupt a replay and open a new connection- it seems that this is quite non-trivial to get right. I've decided to complete the delta dump generator instead. Unfortunately, this means that I won't have a complete chain to show a remote helper by mid-term evaluations: just individual components. 2. Ternary treap fork. This only changes the underlying data structure- nothing else should change. David is close to completing this. 3. Make svn-fe support deltified dumps. This can only be done after we have a Git object store backing. Deferred for the moment. 4. git-fast-import only supports filecopy for trees from the parent commit; make it support copies from all commits. Jonathan has already sent an RFC patch on the list for this. 5. Zero-tree fork. svn-fe currently maintains trees for all revisions; Jonathan suggested that it can lazily fetch tree objects from the Git store backing. This change will significantly reduce the complexity of svn-fe. 6. git-fast-import needs to be extended to print-marks. Sverre suggested this, and Jonathan has sent an RFC patch on the list. This is required for the Git object store to communicate back commit hashes to the caller (svn-fe in this case). In other news, we managed to get colabti.org to log the channel where we have most of our discussions: #git-devel on Freenode IRC. This information is probably helpful for other GSoC students and developers who are looking to collaborate on projects. -- Ram ``` ## Bo Yang, 2010-07-02 01:40 Subject: Re: [GSoC update] git-remote-svn: Week 9 Message-ID: URL: https://gitlist.dev/e/AANLkTikWHW7bZ61lTnhkJ_kYyV-193sKsztPR-s7gxvM%40mail.gmail.com In-Reply-To: <20100701131310.GA28607@debian> ``` On Thu, Jul 1, 2010 at 9:13 PM, Ramkumar Ramachandra wrote: > > In other news, we managed to get colabti.org to log the channel where > we have most of our discussions: #git-devel on Freenode IRC.
