Cython 0.17 beta 3 released - release candidate

[Stefan Behnel]

Hello everyone,

on behalf of the Cython project team, I'm proud to announce the release of
our third beta of Cython 0.17. This is our first and hopefully last release
candidate for 0.17, another major step forward in the development of the
language that will make life easier for a lot of users, rounds up some
rough edges of the compiler and adds (preliminary) support for CPython 3.3
and PyPy.

* "yield from" delegation between generators (PEP 380)

http://www.python.org/dev/peps/pep-0380/

* alpha quality support for PyPy (via cpyext)

All built/tested OK on fedora (devel).

Build log is here:
http://kojipkgs.fedoraproject.org//work/tasks/8252/4428252/build.log

Should I be concerened about these excluded tests?

Ran 6865 tests in 1601.636s
OK
Following tests excluded because of missing dependencies on your system:
memoryview.memoryviewattrs
memoryview.numpy_memoryview
run.numpy_ValueError_T172
run.numpy_bufacc_T155
run.numpy_cimport
run.numpy_parallel
run.numpy_test

It means that you don't have NumPy installed. I assume there's a Fedora
package of NumPy, so if it's not too much hassle for you, it would help if
you could include them.

OK, this time including numpy in the build, it appears all tests passed OK.

I am just testing cefpython using 0.17 beta3 rc, it works fine under Python 2.7, but when I try to compile under Python 3.2 I get errors, it happens to functions that are exported using 'public' declaration, see errors below (attaching full logs: cython017beta3rc_python32.txt).

I got rid of that error in Python 3.2, the solution was to compile clienthandler.cpp separately by creating a VS project and include only the resulting .lib.

But now I got another error:

C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\link.exe /DLL /nologo /INCREMENTAL:NO /LIBPATH:./ "/LIBPATH:c:/Progr
am Files/Microsoft SDKs/Windows/v7.1/Lib/" /LIBPATH:./../httpauth/Release/ /LIBPATH:./../v8functionhandler/Release/ /LIB

LINK : fatal error LNK1104: cannot open file 'python27.lib'

This is happening when compiling using Python 3.2.

I've found a fix for that too, I had to rename D:\python32\libs\python32.lib to D:\python32\libs\python27.lib - then it works :-) That was easy one.

Cheers,

Czarek.
