For what it's worth, I think that Jan makes some very salient points, such as
> I'd be happy to assist with self-hosting (so gitlab) and perhaps sponsor a container (even a separate machine for CI) but I think the sagemath project would probably be better off on git**b. I'm also hesitant to invest my time in learning trac/gitolite. The bus problem Dima mentioned with self-hosting is valid. But nice to have it as an option for a quick exit (from either git**b) when whatever happens to the companies... The real problem with GH is if we end up locked in. As much hassle as Trac is (and once again, for what it's worth, let me gratefully acknowledge those who are keeping it up and running in whatever state is possible), not being able to get stuff OFF GH is the real issue. For me, the comparison is with learning management systems that many people who have higher teaching loads than the typical core Sage developer (!) are required to use. While there are import-export tools from one to another, they are nontrivial and do not always bring by any means the full content with. In addition, the internal export (say, to pdf or some other transferable medium) can be tiresome in the extreme, when it's even possible. So in some sense we don't have very good control of our own content, which is very frustrating when I want to use something from our LMS that is wholly inside of it. The advantage of Trac is having full control of all the data (among others, but for the sake of this point), as well as the VERY extensive ticket history and seemingly endless discussions (I view those as a strength of the community, on the whole). One really doesn't want to underestimate that. The advantage of GH is nearly completely convenience (and there are many conveniences, Aram's point is very well taken). It sounds like there is a pretty reliable GH -> Gitlab mechanism as well, and people willing to host a GL instance on (French?) academic computers. So is a possible solution to migrate Trac, *including the entire history of discussions*, to GH, and then have a GL mirror of this? It was unclear from the comments in this thread whether one can actually real-time mirror GH in GL, or only export via discrete actions (and presumably not realistically to mirror). Secondarily, one could imagine an automated action that on (say) a point-release basis exports to GL, and that we can point people to that. I'm not sure how contributions from folks who on principle do not want to support GH would work, but doubtless we aren't the only project to have that problem. - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
