I have discovered weird behaviour while debugging a doctest in
dynamic_class.py. A minimal example looks like this:
{{{
$ ./sage -t src/sage/structure/dynamic_class.py
[..]
passed!
[..]
$ touch local/lib/python2.7/site-packages/sage/structure/dynamic_class.py
$ ./sage -t src/sage/structure/dynamic_class.py
[..]
inspect.getfile(Foo2)
Expected:
'.../sage/structure/dynamic_class.pyc'
Got:
'.../local/lib/python2.7/site-
packages/sage/structure/dynamic_class.py'
[..]
}}}
The reason is, that py_compile.compile() produces bytecode different
from what a python call silently creates (other than that, there _seems_
to be no difference).
Now in general, there is nothing wrong with silently generated pyc
files, so imo there shouldn't be a problem in this case.
The simplest solution would be just expecting
{{{
'.../sage/structure/dynamic_class.py...',
}}}
instead, as this will not only pass the test, but also documents the
randomness.
Is there anything else within the sage library that relies on one or the
other outcome of a getfile call?
