It took me a lot of time to realize that I won't be able to finish it alone, unless my free time significantly increases for some reason. This is quite a hard thing to say, considering all the time I've put into this. However, I will now do something I should have done ages ago. There's a tarball attached to this mail with the current state of my work modulo some patches, and I'm asking for help! :-) I've taken some time to write down a TODO list, trying to document all the bugs, ugly parts of the code, missing bits and features, etc... If you feel like implementing something listed there, or something that I forgot to list, you are most welcome. For now, the really big missing feature is the status file support. The lack of this (and maybe some stupidities in my code) explains why csup is so slow as of now. I haven't done any serious benchmarking yet, it'll probably be time to do so once the code for the status file is there. I have a big patch to implement this, but it's nowhere near finished and I haven't touched it in some time. If you want it, just ask and I'll send it over. The other big thing missing is support for CVS mode. This is mostly useful for developers, but it would be a good thing to have. It probably requires a great deal of work. (For those who don't know, CVS mode is used to download the full CVS repository, and not just do a checkout for some tag and/or date). I wouldn't say csup is usable as of now, given that's is quite slow as I just explained. However, I've been running it hundreads of time on my ports tree and as far as I can see it works quite well. Also, to the best of my knowledge it should work on 4.x, 5.x and 6.x FreeBSD systems, regardless of the threading library it is linked to (libthr, libkse and libc_r, need to test with libxu!). It should also work fine whether it is running on x86, amd64, alpha, sparc64, ia64 or even arm. Only powerpc hasn't been tested yet. The current codebase should also already constitute a great documentation of the CVSup protocal, and I hope people will enjoy reading this code rather than the Modula-3 code as I had to do :-). Finally, my sincere apologies to everyone for having taken so much time to actually release my code. It was much harder than I thought. Cheers, Maxime --4Ckj6UjgE2iN1+kY--
