I still think it's on the smaller side, but also as you mention below we have usually been rather optimistic about project sizes. So maybe this is the right size for a GSoC after all. > Yeah, the naming and workflow discussions should actually happen when > discussing the student's proposal, in which case an important part of > the work will (hopefully) be done before the GSoC actually starts. > > Historically though we have always been very optimistic in what we > thought a student could accomplish in a GSoC.

I think there's still a number of things that could do with some refactoring in 'builtin/stash.c', e.g. use more of the libgit.a API, instead of using the run_command API, or potentially other improvements that could be made. Another thing that may be useful to do is to write down some actual technical documentation on the format of what a stash commit looks like. > I have added a "Note about refactoring projects versus projects that > implement new features" at the end of the idea list: > > https://github.com/git/git.github.io/blob/master/SoC-2019-Ideas.md#note-about-refactoring-projects-versus-projects-that-implement-new-features > > and I think that with that note students working on such projects will > be warned enough, and therefore hopefully have a better chance of > success. > > So after all if you are willing to co-mentor such a project, I would > be ok to co-mentor it with you, and we should add it to the list.
