Files

• New PARI spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/pari-2.4.3.svn-12577.p3.spkg

• New genus2reduction spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/genus2reduction-0.3.p8.spkg

• New lcalc spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/lcalc-20100428-1.23.p2.spkg

• Patch for data/extcode: extcode_9343_combined3.patch

For reviewers

• Download sage-4.6.prealpha1.tar, which is a complete Sage distribution based on sage-4.5.3.alpha1. Just extract it, and type make. In this file, the following tickets have been merged:

  • 9343 (needs_work): PARI upgrade

  • 9591 (needs_review): genus2reduction

  • 9592 (needs_review): lcalc

  • 9750 (positive_review): Document that PARI no longer assumes more than GRH

  • 9636 (needs_review): Catch output from PARI in Sage

• The main issue seems to be making sure it actually compiles.

• For reference, these are the patches for the spkg's:

  • pari

  • genus2reduction (note that old genus2reduction.c file was not under revision control unfortunately)

  • lcalc

Known issues

• It doesn't build on t2.math.washington.edu

  • jdemeyer: I will have a look at this once I get a working account on this machine.

• Tuning (i.e. building with SAGE_PARI_tune=yes) is completely broken.

  • Upstream issue, reported as http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1089

  • Not essential for this ticket (tuning is disabled by default anyway).

• Build issues on Fedora 13: see 9722
