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
