| = 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/9845|#9845]] for a later lcalc spkg based on this one) * [[http://trac.sagemath.org/sage_trac/ticket/9722|9722]]: PARI/GP build error on Fedora 13 (Merged into Sage 4.5.3.alpha2. I'm currently porting the changes to the PARI 2.4.3.svn-12577.p4 spkg. -Leif) == Files == If you want to upgrade an existing Sage, you have to install 3 spkgs 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/mpatel/trac/9591/genus2reduction-0.3.p8.spkg * lcalc spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/lcalc-20100428-1.23.p2.spkg (or alternatively the lastest, http://sage.math.washington.edu/home/mhansen/lcalc-20100428-1.23.p4.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]] (positive_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]] (closed): 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]] (closed): Numerical noise on {{{sage/stats/hmm/chmm.pyx}}} on both Solaris x86 and OpenSolaris x86. * The above two tickets have nothing to do 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 spkgs: * [[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 the 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.p4.spkg|pari-2.4.3.svn-12577.p4.spkg]] and then type the following in a shell: {{{ tar xjf pari-2.4.3.svn-12577.p4.spkg cd pari-2.4.3.svn-12577.p4/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_TUNE_pari=yes}}}) is broken. * Fix upstream in latest svn, see the bug report reported as http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1089 * Build issues on Fedora 13: see [[http://trac.sagemath.org/sage_trac/ticket/9722|9722]]. (Not all are limited to Fedora 13, i.e. could in principle occur on other systems as well.) |
