[PATCH 1/6] G_eval: fix incorrect use of STL iterator.
by Alexei Sheplyakov 08 Aug '09

08 Aug '09

According to [lib.bidirectional.iterators] it's not OK to decrement an iterator pointing to the beginning of the sequence. Fortunately random access iterators provided by (current versions of) gcc/libstdc++ don't have this silly limitation, so the code which works with pointers works with iterators without any changes at all. However, - there's no guarantee that the current behavior won't change in the future - some non-GNU compilers are not that smart (i.e. the program segfaults upon when decrementing beginning-of-the-sequence iterator). --- ginac/inifcns_nstdsums.cpp | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/ginac/inifcns_nstdsums.cpp b/ginac/inifcns_nstdsums.cpp index 2c4061a..b410533 100644 --- a/ginac/inifcns_nstdsums.cpp +++ b/ginac/inifcns_nstdsums.cpp @@ -569,11 +569,12 @@ ex G_eval(const Gparameter& a, int scale, const exvector& gsyms) Gparameter newa; Gparameter::const_iterator it2 = short_a.begin(); - for (--it2; it2 != it;) { - ++it2; + for (; it2 != it; ++it2) { newa.push_back(*it2); } + newa.push_back(*it); newa.push_back(a[0]); + it2 = it; ++it2; for (; it2 != short_a.end(); ++it2) { newa.push_back(*it2); -- 1.6.3.3

Debian files in git repository
by Richard B. Kreckel 04 Aug '09

Hi, I suppose nobody really cares about the debian/ directory. The files in there have not been maintained well, lately. Of course, this is because their lifecycle is better maintained over with the Debian packages. Anybody who cares about these files knows where they are: they are contained in the ginac_*.diff.gz files in the Debian package pool. Unless somebody speaks up, I will remove them from the repository, soon. Cheers -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>

[SCM] GiNaC -- a C++ library for symbolic computations branch, master, updated. release_1-4-0-191-gf38cbcd

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "GiNaC -- a C++ library for symbolic computations". The branch, master has been updated via f38cbcd651246fb5c1294705d29399f3cbfddaf5 (commit) via feed241b95f7dbd6294795b4afc2bcae41880c31 (commit) from 71803f13294618ddd3f19fd0d9871cc44023c155 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit f38cbcd651246fb5c1294705d29399f3cbfddaf5 Author: Jens Vollinga <jensv(a)nikhef.nl> Date: Fri Jul 10 15:01:04 2009 +0200 Changed the parser such that it understands all defined functions including the user defined ones.
