Description (last modified by )
This patch fixes the parent and element classes for Hom categories to be purely abstract, and simplifies the Hom logic:
 Unified the logic for selecting the class when building a Homset (e.g. Homset, RingHomset?, HeckeModuleHomspace?, ...). This is now systematically done through the _Hom_ hook. The logic still has a fundamental flaw, but that's for the later #10668.
 The cache for Hom is handled at a single point in Hom In particular, homsets created via the _Hom_ hook are now unique.
 If category is None, Hom simply calls itself with the meet of the categories of the parent, which removes a cache handling duplication.
 Parent.Hom calls Hom directly (removes duplicate _Hom_ logic).
 ParentWithBase?.Hom was redundant and is gone.
 Reduce the footprint of the current trick to delegate Hom(F,F)(on_basis=...) to module_morphism, allow for the diagonal option too, an make sure the homset category is set properly.
 Update a doctest in sage.modules.vector_space_homspace to take into account that homsets created via _Hom_ are now unique.
 Scheme is (apparently) an abstract base class; so it should not be instantiated. I changed some doctests in sage.schemes.generic.SchemeMorphism? to use instead the concrete Spec(ZZ). Those doctests were breaking because Scheme does not implement equality, which is required for Hom caching.
As a byproduct, the HeckeModules? category does not import any more HeckeModulesHomspace?, which was a recurrent source of import loops.

Note: there are two doctests failures that I don't know how to handle, related to the refcounting of Singular rings::

 Work issues set to Fix ring_refcount_dict problem
With #12808, #12875 and #12877 applied on top of sage5.1.notebook, all doctests pass. But when adding the patch from here, there are two problems:
sage t force_lib "devel/sage/sage/libs/singular/ring.pyx" sage t force_lib "devel/sage/sage/rings/polynomial/multi_polynomial_libsingular.pyx"
Namely:

So, apparently it is only a single problem.

Yeah, I know (see comment 3 above). I feel quite stuck with those failures, and would really appreciate if you could investigate them since you know much better than me the caching for Singular rings.

Why do you import Sets (new line 221)?
Do I understand correctly: If Hom receives None as category, then you determine the category as the meet of the categories of domain and codomain, and call Hom again. Did you test that the calling overhead does not matter?
comment:18 followup: ↓ 28 Changed 10 years ago by
Another point: I had inserted a comment in #11521, namely "Apparently _Hom_ is supposed to be cached." This is why I did not insert stuff in the (weak) cache.
Do you lift that assumption? Then, we should see what _Hom_ methods actually do caching. They should at most do weak caching.

 Status changed from needs_work to needs_review
I have rebased your patch relative to #11521 (as I said: This already has positive review).
Please have a look whether you are happy with my changes: I only changed sage/categories/homset.py, by using the :trac: directive in two places, fixing one hunk that has only applied with fuzz and removing the import of Sets. Apart from that, I adopted your logic of constructing the homset.
So far, I have tested sage/categories/homset.py and have verified that the previously failing tests are indeed fixed by #11521 (in fact, I also had some other pathes applied, but I am convinced that ##11521 suffices). I am now running the full tests suite, with only #11521 (and its dependency #715) and the new patch (and its dependencies #12875 and #12877).

Hm. With sage5.0.beta13 plus #715, #11521, #12875, #12877 and trac_12876_categoryfix_abstract_classntrel11521.patch, I get one error, namely a segfault in
sage t force_lib "devel/sage/sage/rings/number_field/number_field_rel.py"
But strange enough: When I ran it with verbose, all tests passed, and the segfault came from leaving sage. That reminds me another problem: The deallocation of the (unique) pari instance is not done as it is supposed to be. This is fixed by the second patch of #12215. Hence, I am trying again, with #12215 added.
comment:21 followup: ↓ 26 Changed 10 years ago by
Yes! Adding #12215 fixes the segfault. I am now running doctests. Do you mind adding it as another dependency, provided that the test suite passes?

I made some additional cosmetic changes in a reviewer patch.
Further questions:
In sage/category/hecke_modules.py, you refer to ticket number ??? for fixing _test_zero and _test_elements. In sage/schemes/elliptic_curves/ell_curve_isogeny.py, you leave a reference to trac open as well. Have the tickets now been created? I didn't fix that yet.
I see that you rename Rings.HomCategory.ParentMethods.__new__
into __new__bx
. Does that mean the ugly __new__
method ought to be removed (finally!)?
But then, shouldn't __getnewargs__
be removed as well?
Please tell whether you want to address these questions in an additional patch. And I hope you agree with adding #715, #11521 and #12215 to the dependencies? Only #12215 needs review (hint...).
If you do agree, then put this to positive review, please.

Sorry, I made a lastminute change in the reviewer patch (namely, by mistake, I changed "ticket ???" into "ticket 12876", but I think ??? really refers to a ticket that has not been created, yet. Anyway, feel free to change ??? into something real! And disregard trac_12876reviewer.2.patch, which was created by mistake.

comment:24 Changed 10 years ago by
I tried whether one can remove the __new__
and __getnewargs__
methods. However, when doing so, one gets a reproducible timeout in the tests for sage/rings/polynomial/multi_polynomial_sequence.py  that's the only error.
So, better keep it as it is.
Recall: I would give it a positive review, if you agree with the additional dependencies.

I did not test it. But it simplifies quite much the logic and the calling overhead occurs only for the first call, so I assumed it was negligible.

Oops. Those are #12879 and #12880 respectively.
I see that you rename
Rings.HomCategory.ParentMethods.__new__
into__new__bx
. Does that mean the ugly__new__
method ought to be removed (finally!)? But then, shouldn't__getnewargs__

Yes, that was my intention indeed: in principle they should not be needed, and I forgot to remove them. I'll investigate the failure you report on Monday, unless you beat me to it.
Please tell whether you want to address these questions in an additional patch.
Unless removing getnewargs turns out to be hard, I'd rather fix all of the above right now. Feel free to experiment: I won't download the patches before Monday.
Thanks a lot for all your quick work on this :)

Yes: I consider that all the caching logic should be in Hom; in particular the _Hom_ methods should not do caching (and if I recall correctly, they currently don't). We should probably add a note about this in the documentation of Hom.

I have uploaded a reviewer's patch which fixes the trac ticket numbers, and removes completely Rings.HomCategory?. I could not reproduce the timeout:

Ok, this is totally benign. Now, to minimize change, the easiest is probably to keep the HomCategory? even if we delete its containt. The updated reviewer's patch does just that.

I'm afraid it still needs a tiny bit of work. make ptestlong
resulted in (only) one error, namely

Apparently this is caused by emptying the HomCategory of Rings().

PS: The obvious fix is to change the expected result in the test...

Me stupid! The failing test is only introduced in #11768. So, I had better not apply more than the necessary patches...
Running the failing tests without the additional patch works.
Hence, repeating the test suite now... Sorry!

Now it works. It is thus a positive review.

 Description modified (diff)
 Status changed from needs_work to needs_review
I have replaced Nicolas' first patch, under a new name. The changes became necessary by changes in the patches at #715 and #12313. Now I am running doctests.
Apply trac_12876_categoryfix_abstract_classskrel11521.patch trac_12876reviewer.patch trac_12876_categoryfix_abstract_classntrel11521reviewnt.patch
Note: this might depend on #12875
