[sage-devel] help with a failing doctest in symbolics (#9582)

For those of you that don't follow sage-release, there's only one ticket that's really holding up 4.5.2: #9582. There are some tests in symbolics that fail on OS X because the terms are printed in a different order. I don't know how to fix this, but I'll bet one of you does! If we close this ticke

[sage-devel] Parents and categories best practices?

Dear sage-devel, I'm a bit confused about what the recommended way to implement a free module is. In particular, I would like a custom parent and elements classes and coercion into the module. For simplicity, lets assume that speed is not an issue. It seems like there are at least three options:

[sage-devel] Rational polynomials via FLINT (#4000)

Dear all, A mere two years after ticket #4000 was opened on trac and a little work during Sage Days 24 in Linz, there is now a set of patches (ready for review!) attached to the ticket that provides an implementation of QQ[] via FLINT 1. This note's main purpose is to let everyone know about this

[sage-devel] Making 32-bit PARI pretend to be 64-bit

Hello all, My working on the big PARI-upgrade (#9343) has sprouted many ideas. One of these (possibly crazy) ideas is the following: we might manage to some extent to make 32-bit PARI behave like 64-bit PARI. Because right now various doctests return different results depending on the word size

Currently if a test fails in the doctest, one can never be sure if the machine may have run out of swap space, disk space disk I/O problems or all manner of other things that could cause test failures. But if the time of the failure was recorded, then the system logs could be used to see if anythi
