It doesn't require that you distribute the tools for editing the source, though. For example I believe it is fine to distribute a program for Microsoft Visual Studio, in the form of the files you would actually use with Visual Studio, even though the format of some of those files is not documented. > Providing the source in BK form without BK is as useless as > providing it encrypted.

I disagree, because the BK file format is actually quite well documented - it is SCCS with some annotations that do not seem essential if you are using a different tool. The data is easily extracted using an SCCS-compatible tool. It is certainly not encrypted, and I had no difficulty writing a Perl script to extract any version of the source, although I have yet to look if changesets are so easy as individual files. Credit to Larry, for choosing an easily read file format. (Although not perfectly - see the CSSC documentation for some things that they are not sure how to decode in an SCCS file - and yes, those do appear in BK-generated SCCS files from time to time). > If BitKeeper is the version management tool, then BitKeeper is part > of the source by this definition. Linus and other people have said repeatedly that BitKeeper is _not_ essential to working with them on the kernel. That said, it does seem that if you can't read bkbits.net, then you are at a disadvantage sometimes. -- Jamie - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
