[Cython] releasing 0.18?

2012-12-15 Thread Stefan Behnel 
Hi,

the current master doesn't really have the one new, great&shiny feature,
but I don't see a reason to keep the changes back that we have implemented
so far. Robert's const support and the integer overflow checks (assuming
that both are ready) are certainly worth it. Unless Mark's minivect changes
are ready to merge soonish, I don't think we should keep waiting for them.

So, what about getting the master ready for a release?

Note that this means that we need a couple of more comments in the
changelog, as well as documentation for the things that need it (const?).

Next package's tree will not work and will return error

I'm sure it's not - the compile time package resolution code in Cython was
written long before namespace packages were even being thought about. (For
comparison, remember that almost none of the existing CPython versions
supports namespaces packages either, 3.3 is the only exception).

Basically, the runtime import code should be ok, but the package resolution
at compile time, that is used mainly for cimports and for figuring out the
fully qualified module name of compiled modules, doesn't have any support
for packages that don't have an __init__.py.

Would you care to change that? You could try to come up with a patch, we'd
certainly appreciate it.

Following changes works for me. But I did not made any tests except on 
package I've sent in initial message.

Great. There was an issue with extension types as dtype in
memoryviews, which I hope to have a look at tomorrow.
