Going 1.5?
by Jens Vollinga 01 Dec '08

01 Dec '08

Hi, I'd like to start a discussion about making a major release (1.5). From my side, I'd like to finish the factorization first before doing such a release. But I think this only amounts to putting lots of comments in the sources and adding a section to the tutorial. That will be done relatively soon. So, in principle I could aim for a release next week. What do the other developers think about a major release? What time would be welcome? Maybe there are some pending new features or just items on a private todo list that should be finished first? Regards, Jens

Bug in sqrfree
by Jens Vollinga 01 Dec '08

01 Dec '08

Hi, there seems to be a bug in the sqrfree function in GiNaC. The attached program when run will sooner or later stall (stuck in an infinite loop inside sqrfree()). I am not too familiar with the new code there, so I'd first like to ask the other devs whether they have any idea about it? Regards, Jens

The libtool naming scheme cannot guarantee that on all systems, the numbering is consecutive. It only guarantees that it is increasing. This doesn't matter, though: there is not incurred cost for numbers that are omitted, except for shrinking the available space of leftover numbers. Not something we need to worry about yet. ;-) On the other hand, tricks which we were using to make version numbers consecutive on GNU/Linux break versioning on other OSes. commit c277943ace48d2f22f7016ba9439ff7cb949a231 Author: Jens Vollinga <jensv(a)balin.nikhef.nl> Date: Mon Dec 1 09:54:53 2008 +0100 Fixed a problem in polynomial divide by deactivating a recursion that lead to a significant slowdown in sqrfree() and sometimes to a infinite loop. ----------------------------------------------------------------------- Summary of changes: configure.ac | 51 +++++++++++++++++++++++++-------------------------- ginac/normal.cpp | 13 +++++++------ ginac/version.h.in | 12 ++++++++---- 3 files changed, 40 insertions(+), 36 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

It also returns the chosen prime. This supports the factor_multivariate() code. Polynomials are expanded before calling factor_sqrfree(). This avoids problems with some input polynomials. Added static qualifiers to all hidden functions. commit a17a77e5c3d4ec2a92804debac65c75921f0156d Author: Jens Vollinga <jensv(a)balin.nikhef.nl> Date: Tue Nov 11 10:33:29 2008 +0100 Fixed a bug in squarefree(). Some polynomials were erroneously classified as square free (e.g. x^prime+1). Fixed a bug in multivar_diophant() causing sporadically an infinite loop. Improved lifting bound code. Univariate lifting can now use a cache for the modular factors. At the moment, this gives no measurable speed gain. commit edc92b7a463993da62357fb4afad053e8c6d0771 Author: Jens Vollinga <jensv(a)balin.nikhef.nl> Date: Mon Nov 10 13:38:11 2008 +0100 Added modular square free factorization.

GiNaC release 1.4.4
by Jens Vollinga 07 Nov '08

07 Nov '08

Hello everybody, GiNaC 1.4.4 is out and available. The changes are: * Fixed a bug in the multiple polylogarithms Li/G that caused imaginary parts of the arguments to be ignored. * Fixed archiving of complex numbers. * Made the behaviour of class function more consistent with respect to ncmul::eval(). * Fixed a bug in power::is_polynomial. * Improved heur_gcd() so it can handle rational polynomials. * Improved build scripts. As always, this release can be downloaded from http://www.ginac.de/Download.html Best wishes, Jens

Maybe this happens only on OpenBSD? Sounds strange. I use cln 1.2.2 and gcc 4.3.1. Maybe the bug is related to these tools? > The configure patch is for detecting and enabling ::compile stuff, it > might be OpenBSD specific, but it would be cool if you could make a separate > case for that upstream. I also don't know how to treat this one. Your patch applies to "configure". But in the source "configure.ac" LIBS is not explicitly extended by "-ldl", only DL_LIBS. So, this seems like we cannot repair it. Maybe autoconf mixes it up? > The ginac-examples texi was missing a directory entry for info, you > should add that upstream. > And the Makefile.in patch removes the release target in order to > generate proper .so with proper versioning. I applied these both. Thanks! Regards, Jens
