Now we get to the tests, there are a lot here and we may not have time to help
you with all of them in detail. I can see the following are quite significant:
- sympy errors, you probably have to backport python-sympy.
- FutureWarning from matplotlib, you probably have to backport python-matplotlib
- SignalError: Segmentation fault when calculating groebner_basis(), Tobias
dealt with this back in January and he might have some more comments to add. I
see you already backported python-brial but perhaps you also need to revert
some stuff we added for GCC-6 support.
If you run the build with sbuild using one of the release-* targets in
debian/rules, it will give you a shell after a failed build, and then you can
run something like `make -f debian/tests.mk LOGFILE=sage/logs/ptestlong.log
failed-tests-by-error` to analyse the output to figure out which issues are
"more significant" to fix first.
You can also run this on the file that you just uploaded, although the output
contains some junk because the input contains extra stuff it's not expecting.
It's still useful though; if I run:
$ make -f debian/tests.mk LOGFILE=../sagemath_7.4-9~bpo8+1_amd64.build
failed-tests-by-error
I can also see:
33 IOError: [Errno 2] No such file or directory:
'/usr/share/sagemath/graphs/smallgraphs.txt'
41 IOError: [Errno 2] No such file or directory:
'/usr/share/sagemath/graphs/brouwer_srg_database.json'
So you probably need to backport these as well:
$ dpkg -S /usr/share/sagemath/graphs/smallgraphs.txt
sagemath-database-graphs: /usr/share/sagemath/graphs/smallgraphs.txt
$ dpkg -S /usr/share/sagemath/graphs/brouwer_srg_database.json
sagemath-database-graphs: /usr/share/sagemath/graphs/brouwer_srg_database.json
