As I recall, a bit part of what prevented more going into submodule--helper was isolating the_repository and allowing multiple repositories in-memory at once. That effort has stalled since Stephan has moved to other things. (I will also admit that perhaps I am wrong: is it complete, rather than stalled?) I would be happy to see more progress in this area, and it could be a good way to get familiar with the codebase and submitting patches. > Realistically, I think that it would be possible for a GSoC student who is > already very familiar with the code base and with submodules to finish the > conversion of `git submodule` in one season. Even assuming the most generous definition of "very familiar" I'm not sure this is the case. But I also don't meet the bar of "very familiar" when it comes to the submodule code. So, I'm sending this message just to say "DRAGONS BE HERE" and recommend taking on a smaller project. Thanks, -Stolee
