comment:5 Changed 5 years ago by
still not ok, for some reason related to symbolic rings. Remains 2 failing doctests.
sage -t src/sage/rings/padics/factory.py # 2 doctests failed

Let me summarize the problem:
sage: x = var('x')
sage: X.<a> = Qq(27, modulus = x^3 + 2*x + 1)
sage: P.<x> = ZZ[]
sage: R.<a> = Qq(27, modulus = x^3 + 2*x + 1)
sage: X == R
False
sage: X._cmp_(R)
1
sage: X.__richcmp__(R, 2)
True
So the default behavior for == is apparently to call _cmp_ in Parent which calls __cmp__. Therefore one may have to change the behaviour in Parent to first call __richcmp__ before being able to handle this.

WTF? You implemented __richcmp__ in a pure Python file? That doesn't do anything...

We put it there as a perfect use-case for #23102. :P
