Blaaaargh!
OK. So I was working on the problem of fixing dpkg-dev so that
foo Depends: foo-data {SourceVersion}, foo-libs {BinaryVersion}
or something similar actually works. By parsing the version numbers.
Now it's apparently been changed under our noses, in such a way that my
proposed
scheme won't work -- and furthermore anyone who implemented their own
version
of such code, in their own package, will find it magically broken.
Thanks to Goswin and Henrique for *notifying* people of this, since
apparently whoever changed it didn't think about the impacts on other
developers.
Instead binNMU versions are now made by adding +b1 (+b2, +b3) to the
version and containing a "Source: foo (non-NMU version)" line. The
later makes it possible to reliable associate binNMUs with their
source.
So how do we write a package Depends: line now? Apparently the buildd uses
the original source,
and adds a changelog entry -- *but what happens to the {SourceVersion}
substitution?* Does the buildd
alter the substvars file before compiling? Does the {SourceVersion}
substitution end up being the original 1.2-3 source version, or the 1.2-3+b4
version? Whichever it ends up being, *how do we get the other one* if we
need it?
