Hey everyone,
I just upgraded my version of Ubunutu from 16.04 LTS to 17.10, and I can
no longer run doctests with 8.2.beta8:
travis@apricot:~/sage-build$ ./sage -t src/sage/combinat/partition.py
too many failed tests, not using stored timings
Traceback (most recent call last):
File "/home/travis/sage-build/src/bin/sage-runtests", line 127, in
<module>
err = DC.run()
File
"/home/travis/sage-build/local/lib/python2.7/site-packages/sage/doctest/control.py"
, line 1138, in run
self.test_safe_directory()
File
"/home/travis/sage-build/local/lib/python2.7/site-packages/sage/doctest/control.py"

.format(os.getcwd()))
RuntimeError: refusing to run doctests from the current directory
'/home/travis/sage-build' since untrusted users could put files in this
directory, making it unsafe to run Sage code from
I also tested this with version 8.1.beta3 I happen to also have on my
system. I get an error message of the form
sys:1: RuntimeWarning: not adding directory '' to sys.path since it's
writable by an untrusted group.
Untrusted users could put files in this directory which might then be
imported by your Python code. As a general precaution from similar
exploits, you should not execute Python code from this directory
and then it seems to be very poorly handled after that. I also get:
travis@apricot:~/sage$ ./sage
sys:1: RuntimeWarning: not adding directory '' to sys.path since it's
writable by an untrusted group.
Untrusted users could put files in this directory which might then be
imported by your Python code. As a general precaution from similar
exploits, you should not execute Python code from this directory
which I do not get with 8.2.beta8.
Any ideas on how to fix this? Of course, I could change the permissions of
the folder(s), but that feels like bringing a bazooka to a fist fight.
Thanks,
Travis
