Hi Simon,

I reworked the patch by adding features to dynamic_class in order to avoid logic duplication and encapsulation breaking in make_named_class.

The downside is that this makes this ticket depend on #12876 (ensuring that parent/element classes are purely abstract).

All test should pass on 5.0.beta13, except for the two issues I mentionned in #12876. Oh, and one trivial failure I had forgotten in semigroup_cython.pyx. I'll update the patch later (tonight?) but you can start the review.

I folded the two patches to get a better overview. You can access the differential patch by looking up ​http://combinat.sagemath.org/patches/file/3121811e2ebe/trac11935_weak_pickling_by_construction_rel11943-review-nt.patch.

Cheers,

Nicolas

    v44 v51  
    11At #11900 and [http://groups.google.com/group/sage-combinat-devel/browse_thread/thread/99c74827d704e677 sage-combinat-devel], as well as in some comments in sage/categories/category.py, the idea was discussed to make, for example, `Algebras(GF(3)).parent_class==Algebras(GF(5)).parent_class` - hence, make the parent/element classes as independent from the base of a category as possible.

     3This is implemented in this patch by introducing an abstract class
     4CategoryWithParameters which uses pickling by "weak construction" for
     5its element and parent classes. In the process, this patch also:
     6
     7- Adds a method Category._make_named_class providing a unified way to
     8  create parent and element classes (and later on morphism classes)
     9- Extends the interface of dynamic_class to customize caching and pickling
