# [with patch; positive review] followup to #2169 -- (magma/sage interface) some further optimizations and fixes

Reported by: Owned by: William Stein William Stein major sage-3.2 interfaces editor_craigcitro N/A

### Description

Apply the patches from #2169, then apply both these patches. To test do

sage -t --optional SAGE_ROOT/devel/sage/sage/interfaces/magma.py


Conversion of Magma matrices over ZZ back to Sage should also be much faster now.

Apply all the attached files -- the sage- ones to hg_sage and the extcode ones to hg_extcode.

I get a reject with http://sagetrac.org/sage_trac/attachment/ticket/2171/sage-trac2171.patch on rc1. It looks like it is depending on a patch that isn't there. This is the failure:

Milestone: sage-2.11 → sage-2.10.4

The patch that this code depends on is attached to trac #2120. I guess this will have to wait until that patch is ready to go? Or should we pull over that part of the patch to this ticket so we can get it merged? William, what's the status of the Maple ticket?

Craig,

can you review this? It has been potentially bitrotting for a long, long time :)

Cheers,

Michael

I rebased these patches against 3.2.alpha0 and got rid of the dependence on #2120. This should be easy to apply and go into sage-3.2.

Milestone: sage-3.2.1 → sage-3.2

In sage-trac2171-part1.patch there is still a change to sage/interfaces/maple.py. I will delete that hunk and test the patch. Other than that I expect a positive review assuming the doctests pass.

Cheers,

Michael

For the patch extcode-trac2171-part2.patch, here's a possible documentation fix:

-{Conver the ring of integers to Sage.}
+{Convert the ring of integers to Sage.}


Positive review.

Cheers,

Michael

Resolution: → fixed new → closed

Merged sage-trac2171-part1.patch and sage-trac2171-part2.patch in Sage 3.2.alpha1

Oops, I didn't merge extcode-trac2171.patch and extcode-trac2171-part2.patch. Those two patches have been merged in Sage 3.2.alpha2.

Cheers,

Michael
