New description:
John Cremona tells me that: "All data for elliptic curves of conductors
from 130k to 180k 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 180000,
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://wstein.org/home/ohanar/cremona-
database/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.patch] to the Sage library.
Apply [attachment:trac_11587-depfix.patch] to Sage root.

Comment(by rohana):
Ok, I've updated the spkg, it now includes updating instructions in the
spkg.txt as well. I've also added a patch that removes the hardcoded
version numbers from the sage library, the instructions in the spkg are
based off of this.
