I think you need something a bit more expressive than reposurgeon's format to do SVN<->Git conversion well, and I think you need something a bit more accessible in order to document SVN edge cases. For example, I don't see how reposurgeon could represent all the madness around SVN cherry-picks that become merges when you manually add information from revision logs, then become cherry-picks again when you find a revert coming in from another branch. Having said that, a (lossy) conversion between SBL and reposurgeon format would probably be useful and not that hard. The link above put it very well that most people leave an embarrassed “to be done” comment and disappear when they realise how much of a nightmare the mapping is. What it doesn't mention is that everyone experiences a slightly different part of the nightmare, and that we can only really tackle the problem by getting everyone's freaky edge cases written up in one language in one place. The test suite[1] isn't that impressive right now, but in the long-term I'm really keen to get implementers to pool their knowledge so we can all benefit. SBL is designed to let people open the relevant test without reading the spec and say "oh right I understand what a piecemeal merge is now. I'll go implement that in my project". I'm currently working on code to read an SVN dump and write to SBL. This will definitely overlap with reposurgeon's SVN export functionality, but without seeing the final code I can't say how much. That's fine though - as I say, the only way to get a good solution is for multiple implementers to investigate the problem and share the edge cases they find. - Andrew [1]https://github.com/andrew-sayers/SVN-Branching-Language/tree/master/t -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
