Bug#845179: FTBFS with super-fresh cython -- seems to carry pre-cythoned sources which get rebuilt during clean

[Tanguy Ortolo]

While preparing for upload of fresh cython (0.25.2~b0-1) and running build of
rdepends python-aiohttp failed to build with

so you can see that clean does recythonizing, which modifies shipped with
upstream tarball slixmpp-1.2.1/slixmpp/stringprep.c

Thanks for catching this!

Well, I am not surprised that generating it again with a newer version of Cython results in something a bit different. :-)

as a quick&dirty solution (besides cleansing the sources pkg) I think you
could make use of  dh_autoreconf so it memorizes changed files

I already had the case with a package written in Vala and shipped with pre-generated C file: what I did then was simply to delete these files during clean. This is simple, and good enough since missing files are not an issue if they are not actually needed. I think I will do the same here. Cyrthonizing at clean is silly, but this seems to be a known limitation of the current integration of Cython and distutils… I guess we will have to deal with it, as the only consequence will be using the CPU for nothing.
