Doctest failure in sage_object.pyx when test run as root

    sage: sage.structure.sage_object.picklejar(1, dir + '/noaccess')
Expected:
    Traceback (most recent call last):

    OSError: ...
Got nothing
*******************************************************************

the doctest creates a directory and sets permissions to 0000. if running as root no error is thrown when accessing this directory, hence the failure of the doctest.

Proposed fix: check if running the test as root or flag example as no test

patch (see Volker Braun) to avoid error in sage_object.pyx

[emil]

I attached a patch which fixes the error when run as root. However there is no warning about running tests as root which was suggested on sage-devel.

Example: WARNING: You are running doctests as root! It is strongly advised to stop and run the tests as restricted user Are you sure you want to continue as root (y/n)?

There was another ticket mentioned (#5155), maybe it should be implemented there?

Please fill in your real name as Author.

Still get the same error in 5.3, so this is still a minor issue. I filled my real name in the comment of the patch. Where else should I fill it in?

[vbraun]

looks good to me
