Hello sage-combinat,
I just upgraded to Sage 5.11 and everything worked fine (including
tests). Then I installed the combinat patches using 'sage -combinat
install' and Sage crashed at startup. The log file that was generated
ended with:
NameError: name 'cached_method' is not defined
So after a little digging, the problem is missing imports in two files:
devel/sage-combinat/sage/categories/graded_algebras_with_basis.py
devel/sage-combinat/sage/categories/graded_modules_with_basis.py
In both files we should add:
from sage.misc.cachefunc import cached_method
After adding this import, Sage works again.
The fix is easy, but I wondered if it was a problem introduced by some
patch. I think the "culprit" is in one of the patches of #10963.
Specifically I am looking at:
http://combinat.sagemath.org/patches/file/tip/trac_10963-more_functorial_constructions-nt.patch#l8307
This is my first visit to sage-combinat. What is the process of patching
the patch?
Regards,
TB
