Long time no pushout. My old plan was to maintain a "vcs-svn" branch and ask Junio to pull from it periodically. I still plan to do that since I think it's the only feasible way to roll out the larger changes but I might be submitting smaller pieces as patches to the git list directly.
The purpose of this email is to request help --- if you are particularly interested in some subtopic then I would love to see a patch series or pull request on the subject. If I can forget about vcs-svn-pu's existence and just review and accept ready-to-apply patches on the topic as they come, then building a suitable vcs-svn branch will become very, very simple.
The good news is that it's been a calm time, so most of these topics are probably in good shape.

Needs a feature name. Last seen at [1].

Applying this code removal early would make your local branch juggler very, very happy. Might make sense to pair it with some patches to support cat-blob-fd in transport-helper's "import" support, so the UI could be
git fetch svn-dump::/tmp/file.dump
That could (perhaps) partially compensate for the loss of convenience from requiring the cat-blob-fd to be plumbed correctly. It's a shame we weren't louder about svn-fe's command line usage being subject to change. Live and learn. :/

That's silly --- this long overdue cleanup does not require anything except db/fast-import-blob-access. Building it on top of db/prop-delta seems okay, since the latter is simple and known to work well.

Killer feature. After db/optimize-vcs-svn it is easy. It does not need to wait for Text-delta and svndiff0 support.

With those three topics out of the way, the rest of the wishlist should be easy. Most of the patches are already written.
- line-buffer enhancements to support Text-delta (multiple buffers, sliding window, temporary files) - svndiff0 parser/interpreter - Text-delta support - Prop-delta support - support for large files - improved error handling - fast-import scalability fixes
