| = New version of PARI/GP: 2.4.3 svn-12577 = == Relevant tickets == * [[http://trac.sagemath.org/sage_trac/ticket/9343|9343]]: PARI upgrade * [[http://trac.sagemath.org/sage_trac/ticket/9591|9591]]: genus2reduction * [[http://trac.sagemath.org/sage_trac/ticket/9592|9592]]: lcalc (see also [[http://trac.sagemath.org/sage_trac/ticket/9775|9775]] for a later version of lcalc) * [[http://trac.sagemath.org/sage_trac/ticket/9722|9722]]: PARI/GP build error on Fedora 13 == Files == If you want to upgrade an existing Sage, you need the install 3 spkg's and apply 2 patches. Do this in order as in the list below. In particular, the genus2reduction spkg will not install without the new pari spkg. * PARI spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/pari-2.4.3.svn-12577.p4.spkg * genus2reduction spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/genus2reduction-0.3.p8.spkg * lcalc spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/lcalc-20100428-1.23.p2.spkg * Patch for {{{data/extcode}}}: [[http://trac.sagemath.org/sage_trac/raw-attachment/ticket/9343/extcode_9343_combined3.patch|extcode_9343_combined3.patch]] * Patch for {{{devel/sage}}}: [[http://trac.sagemath.org/sage_trac/raw-attachment/ticket/9343/sagelib_9343_combined7.patch|sagelib_9343_combined7.patch]] == For reviewers == * Download [[http://sage.math.washington.edu/home/jdemeyer/dist/sage-4.6.prealpha3.tar|sage-4.6.prealpha3.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: * [[http://trac.sagemath.org/sage_trac/ticket/9343|9343]] (needs_work): PARI upgrade * [[http://trac.sagemath.org/sage_trac/ticket/9591|9591]] (needs_review): genus2reduction * [[http://trac.sagemath.org/sage_trac/ticket/9592|9592]] (needs_review): lcalc * [[http://trac.sagemath.org/sage_trac/ticket/9750|9750]] (positive_review): Document that PARI no longer assumes more than GRH * [[http://trac.sagemath.org/sage_trac/ticket/9636|9636]] (needs_review): Catch output from PARI in Sage * [[http://trac.sagemath.org/sage_trac/ticket/9400|9400]] (needs_review): modify the NumberField constructor to pass in optional integer B such that all the internal pari routines will replace the discriminant by its gcd with B, making some things massively faster * This ticket is not strictly related to the PARI upgrade, but it changes a lot of code using PARI. It also fixes an issue with {{{nfinit()}}} and wraps some additional functions in {{{sage/libs/pari/gen.pyx}}}. * [[http://trac.sagemath.org/sage_trac/ticket/9703|9703]] (needs_review): Doctest failures caused by non-working sympow on 32-bit Solaris x86 and 32-bit OpenSolaris * [[http://trac.sagemath.org/sage_trac/ticket/9735|9735]] (positive_review): Numerical noise on sage/stats/hmm/chmm.pyx on both Solaris x86 and OpenSolaris x86 * The above two tickets have nothing to with PARI, but they should make Sage work 100% on Solaris and OpenSolaris. * The main issue seems to be making sure it actually '''compiles'''. * Once it compiles, you can run the '''PARI/GP test suite''' by doing {{{ env SAGE_CHECK=yes ./sage -f pari-2.4.3.svn-12577.p4.spkg }}} * For reference, these are the patches for the spkg's: * [[http://trac.sagemath.org/sage_trac/attachment/ticket/9343/pari_spkg.patch|pari]] * [[http://trac.sagemath.org/sage_trac/attachment/ticket/9591/genus2reduction-spkg.patch|genus2reduction]] (note that old genus2reduction.c file was '''not''' under revision control unfortunately) * [[http://trac.sagemath.org/sage_trac/attachment/ticket/9592/lcalc-spkg.patch|lcalc]] == Debugging PARI/GP build errors == If the new pari spkg doesn't build, you should try building PARI/GP stand-alone (i.e. outside of Sage). You should download [[http://sage.math.washington.edu/home/jdemeyer/spkg/pari-2.4.3.svn-12577.p3.spkg|pari-2.4.3.svn-12577.p3.spkg]] and then type the following in a shell: {{{ tar xjf pari-2.4.3.svn-12577.p3.spkg cd pari-2.4.3.svn-12577.p3/src ./Configure --graphic=none make gp }}} If this works, there is a bug in Sage's build process for PARI/GP. If this gives errors, this indicates an upstream issue with PARI/GP. In any case, any errors should be reported on the Sage trac. == Known issues == * 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 [[http://trac.sagemath.org/sage_trac/ticket/9722|9722]]. |
