[Debian-science-sagemath] Tests timing out

[Tobias Hansen]

Hi,

when I tried sage with libgap 4.8.4 on 12 October I reported that some
tests started timing out. Since then this has always been the case, also
after switching back to gap and libgap 4.8.3. I just tested building at
commit 8dbec07452ecfbee87f0 with a fresh chroot (and I deleted ~/.sage
before) and it still happened that 8 tests timed out. While they are
running, the cpu seems to be idling.

It's still mostly the same tests as with libgap 4.8.4. (Back then
src/sage/modular/abvar/finite_subgroup.py also timed out,
src/sage/rings/integer.pyx did not.):

sage -t --long
src/doc/en/prep/Quickstarts/Statistics-and-Distributions.rst  # Timed out
sage -t --long src/sage/interfaces/expect.py  # Timed out
sage -t --long src/sage/interfaces/interface.py  # Timed out
sage -t --long src/sage/interfaces/r.py  # Timed out
sage -t --long src/sage/misc/sageinspect.py  # Timed out
sage -t --long src/sage/rings/integer.pyx  # Timed out (and interrupt
failed)
sage -t --long src/sage/stats/r.py  # Timed out
sage -t --long /usr/lib/python2.7/dist-packages/sagenb/misc/support.py
# Timed out

I'm not sure how to debug this since there is no output. Any tips?
Ximin, are you running apt-get dist-upgrade occasionally? I'm wondering
why I'm getting this and you not.

Best,
Tobias
