Description (last modified by tscrim)

Currently _test_elements_eq tests for reflexivity, symmetry, and transitivity. However, transitivity does not hold in padic rings. This tickets splits _test_elements_eq into these three subtests, so they that we can override the transitivity test for padic implementations.

comment:11 follow-up: Changed 8 years ago by nthiery

Just a micro comment about the use of this ticket; not its implementation.

However, transitivity does not hold in padic rings

Sounds scary! Well, as long as you know what you are doing :-)

so they that we can override the transitivity test for padic implementations

I am not sure what's your plan for this; just in case, and unless this becomes too cumbersome, I prefer writing explicitly each time: 

    sage: TestSuite(...).run(skip="....transitivity")

rather than systematically disabling the transitivity test. First, that's the occasion to warn the user about an atypical behavior. And to get more people to thing about creative ways of fixing that. Second, the test might actually pass in certain cases, and it's a useful information to record.

Cheers,

Nicolas

I see your point. However, these tests will not pass and there is no way to avoid this (other than disabling == completely). It's an intrinsic problem with padics (or anything that is stored to different precision).

I agree that we could use a skip to warn the user but on the other hand it is probably more confusing...

None of the review patches applies properly for me.

  • Status changed from needs_work to needs_review

I've uploaded a rebased patch to at least 5.9.beta1 and has the review patch folded in. Since this touches a lot of files, I'd like someone with a more recent beta version to make sure it applies before setting this back to positive review.

comment:17 Changed 8 years ago by jdemeyer

Doesn't apply for me. Did you keep in mind the dependency #14284?

comment:18 Changed 8 years ago by tscrim

No, I forgot to check when that was merged. Updated.

comment:27 Changed 8 years ago by roed

  • Status changed from needs_review to needs_work

The last hunk of classical_crystals.py removes a newline before a ::. Otherwise the changes are good.
