Hi, Benedikt! Thanks for your reply clarifying these things.

the hub.darcs.net repository is a mirror of http://code.haskell.org/language-c (the official upstream) that was created to simplify contributing. Conversion to darcs-2 was not straightforward IIRC, and the update of the repository did not work out.That's why code.haskell.org is still darcs-1.

To be able to push to hub.darcs.net, I've done the conversion with "darcs convert darcs-2" with the help of the advices from darcs developers -- after a "darcs optimize reorder", and the resulting darcs-2 repo had no problems with pushing to (a clone of) your darcs-2 repo at hub.darcs.net. (Although one thing that still appears strange to me is that some tags were lost in my result of the conversion, but not in your darcs-2 repo. I've described all this in the previous messages in this thread.) Anyway, now, this darcs-2 mirror of the upstream code.haskell.org darcs-1 repo is at http://hub.darcs.net/imz/language-c_hackage It is "compatible" with your darcs-2 repo at hub.darcs.net, and compared to it has 2 extra patches. These are the last two changes in the "official upstream" darcs-1 repo (they are from December 2014).

I've been interested in hacking language-c library a bit for my needs. (If it turns out useful and successful, I'll tell about it.)

And I've cloned the repo listed at https://hackage.haskell.org/package/language-c-0.4.7 , namely: http://code.haskell.org/language-c

Apart from my special hacks, I've also fixed some typos and so on.

But then I discovered that if I want to publish them on hub.darcs.net , I need a darcs-2 repo, and the initial one which I used for cloning is a darcs-1 repo.

I could do the conversion to darcs-2, but I read that it is not reproducible: run several times on the same set of patches it will give different results.

As I've discovered also a language-c repo at hub.darcs.net which looks like an upstream repo: http://hub.darcs.net/visq/language-c , I'm in doubt whether I should continue making my patches against the darcs-1 repo which is said to be upstream at hackage or against http://hub.darcs.net/visq/language-c whichis not officially declared as the upstream but looks more fresh.

..if I want to be able to send some of my patches upstream.

Best regards, Ivan
