[with patch, merged upstream] Cython circular cdef imports

[gfurnish]

This patch allows circular cdef imports in Cython. It also modifies cython exceptions to also print the line number in the C code. Furthermore the patch begins modifications to seperate module creation from module global execution, which will potentially be useful as Cython starts to employ more optimizations. This patch is required for the symbolics overhaul.

[gfurnish]

Do not apply 9612.patch, apply 9612.2 patch instead. It removed several debug printf statements.

[gfurnish]

New patch, apply this one *only*. Removes more commented code.

[mabshoff]

Mhh, shouldn't this go to the Cython mailing list?

Cheers,

Michael

I am looking into this, but so far it looks good.

Could you post some samples here that don't work with Cython now, but do with your patch applied?

[robertwb]

This wasn't near as scary of a patch as I had first supposed, good work. I merged it into Cython.

Fixes doctests for cython 0.9.6.13

[gfurnish]

This has the new repository hierarchy, so you won't be able to pull
from the online -devel ones. If no one reports any bugs in then I
will release tomorrow.

The spkg at

 http://sage.math.washington.edu/home/robertwb/cython/cython-0.9.6.13.spkg

contains a BUILD directory. I removed it and got the size down to about 100kb over 0.9.6.12.

Cheers,

Michael

[robertwb]

Thanks. This will be removed before the final release.

Merged in Sage 3.0.alpha1

Just to confirm, does this mean in the cython-0.9.6.13.spkg from above (minus the build directory) so I needn't make a separate ticket for the new Cython?

Correct. The ticket's credit and description reflects this.

Cheers,

The spkg up at

 http://sage.math.washington.edu/home/robertwb/cython/

turns c line numbers back on, and has a minor fix for external class declarations (which didn't show up in the Sage codebase, but did for other poeple).

Hi Robert,

I have merged the latest (April 8th) cython.spkg. I saw the message on the Cython mailing list, so I am not surprised that it did come. But I would recommend opening [or reopening] a ticket and also bumping the version number to p0 to reflect this change.

Cheers,

Michael
