| = 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/9756|9756]]: Document SAGE_TUNE_pari in the Sage Installation Guide * [[http://trac.sagemath.org/sage_trac/ticket/9860|9860]]: Port changes in PARI 2.3.5.p4 ([[http://trac.sagemath.org/sage_trac/ticket/9722|#9722]]) to current 2.4.3 == Tickets which can be closed after #9343 is merged == The following lists tickets which seem to be fixed by the new version of PARI/GP: * [[http://trac.sagemath.org/sage_trac/ticket/4794|4794]]: [with spkg, needs work] Update pari to 2.4.3-svn * [[http://trac.sagemath.org/sage_trac/ticket/4835|4835]]: pari starts up without initializing enough primes? * [[http://trac.sagemath.org/sage_trac/ticket/7736|7736]]: factor returns a reducible factor * [[http://trac.sagemath.org/sage_trac/ticket/9175|9175]]: cygwin: pari's sea.gp program segfaults on Cygwin * [[http://trac.sagemath.org/sage_trac/ticket/9518|9518]]: Add an spkg-check file for Pari == 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.p5.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_combined4.patch|extcode_9343_combined4.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.prealpha4.tar|sage-4.6.prealpha4.tar]], which is a complete Sage distribution based on [[http://sage.math.washington.edu/home/release/sage-4.5.3.rc0/|sage-4.5.3.rc0]]. Just extract it, and type {{{make}}}. In this file, the following tickets have been merged: * [[http://trac.sagemath.org/sage_trac/ticket/9343|9343]] (positive_review): PARI upgrade * [[http://trac.sagemath.org/sage_trac/ticket/9860|9860]] (positive_review): Port changes in PARI 2.3.5.p4 (#9722) to current 2.4.3 * [[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/9845|9845]] (needs_review): lcalc doesn't build on cygwin due to missing time.h include * [[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]] (positive_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}}}. * If it compiles, you can run the '''PARI/GP test suite''' and '''test PARI's self-tuning capability''' by doing {{{ env SAGE_CHECK=yes SAGE_TUNE_pari=yes ./sage -f pari-2.4.3.svn-12577.p5.spkg }}} (To keep the spkg's build directory {{{$SAGE_ROOT/spkg/build/pari-2.4.3.svn-12577.p5/}}}, use {{{... ./sage -f -s ...}}} instead. This way you'll be able to inspect PARI's logs of eventual self-test failures.) * For reference, these are the patches for the spkgs: * PARI: [[http://trac.sagemath.org/sage_trac/attachment/ticket/9343/pari_spkg.patch|part 1]], [[http://trac.sagemath.org/sage_trac/attachment/ticket/9860/trac_9860-pari-2.4.3.svn-12577.p4-p5.spkg.patch|part 2]], [[http://trac.sagemath.org/sage_trac/attachment/ticket/9860/pari.p5.patch|part 3]] * [[http://trac.sagemath.org/sage_trac/attachment/ticket/9591/genus2reduction-spkg.2.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.p5.spkg|pari-2.4.3.svn-12577.p5.spkg]] and then type the following in a shell: {{{ tar xjf pari-2.4.3.svn-12577.p5.spkg cd pari-2.4.3.svn-12577.p5/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 has problems on some systems. Since tuning is disabled by default, this is not essential for this ticket. * [[http://trac.sagemath.org/sage_trac/ticket/9876|9876]]: Building PARI/GP with SAGE_CHECK=yes fails on rnfkummer on a PPC Mac OS X 10.4 and on a Solaris SPARC. This looks like an '''upstream problem''' with PARI/GP. |
