I had some recent failure with paver + numpy.distutils + setuptools combination as late as last week. I am not saying it is setuptools's fault (it may well be a problem in numpy), but I can't know for sure because there are many different ways to generate this list of sources. The problem is not doing it with VCS as much as there are many ways in different conditions that only a very few people understand as of today. As a numpy developer who messes quite a bit with distutils and numpy.distutils extensions, I hope we can get rid of all this magic as much as possible. It is ok for *tools* to be magic, as long as they write their *data* to a commonly understood and specified format. But for now, setuptools enforce some behavior that other tools can't mimic, because setuptools' way is implementation defined. And for other parts of packaging, maybe numpy.distutils is implementation defined, without the possibility for other tools to mimic this either. That's why IMHO distutils should be as straightforward as possible, so you can build up things on top of it. Some people like setuptools' behavior w.r.t VCS; but it should be possible for my package and for my potential distutils extensions to stay compatible with distutils, whether I am using setuptools or not. Otherwise, when there are N tools which are all implementation defined for packaging, it becomes intractable very quickly. cheers, David _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
