New description:
John Cremona tells me that: "All data for elliptic curves of conductors
from 130k to 190k is at
http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/data/ and also as a tar
file at
http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/ecdata-2011-08-09.tgz
-- not to mention at http://code.google.com/p/ecdata/ !"
The goal of this ticket is to:
(1) Create a new drop-in-replacement sqlite database that has the data up
to level 10000, which will be included standard with Sage.
(2) Create a new sqlite database that has the data up to level 190000,
which will be an optional spkg.
This is complicated because the current packages in Sage use ZODB. Also,
Cremona's database format has changed somewhat.
There is now a patch that depends upon #11642 (which depends upon #11640).
You can find updated elliptic_curve and database_cremona_ellcurve spkgs at
[http://wstein.org/home/ohanar/cremona-database/].

New spkg:
http://sage.math.washington.edu/home/leif/Sage/spkgs/elliptic_curves-0.3.spkg
Apply [attachment:trac_11587.patch] to the Sage library.
Apply [attachment:trac_11587-docfixes.patch] to the Sage library.
Apply [attachment:trac_11587-rmhardcode.proper.patch] to the Sage library.
Apply [attachment:trac_11587-depfix.patch] to Sage root.

> I fully agree, but unfortunately it's relatively easy to "unmerge" this
ticket, and it's in general not up to the ''release manager'' to fix such
things (that go beyond simple rebasing, fixing noise, permissions or
commit messages etc., which IMHO at least partially already is a
''voluntary'' service).
Of course -- I just meant that you should do the absolute minimum and not
spend effort making the old system more clever. And I just have not had
time to fix the patch.
