New submission from holger krekel <[email protected]>:
Somewhere between python 3.0.1 and 3.1.2 the behaviour of inspect.findsource
changed: it does not find the source code anymore for a code object whose
filename/source is in the linecache.cache because instead of the previous::
file = getsourcefile(object) or getfile(object)
it only does now::
file = getsourcefile(object)
IMO it is enough if findsource() raises if it can't eventually discover the
source code - i don't see the need to do this ahead.
In any case, the r312 findsource version requires an ugly work around within
py.test in order for it to continue to be able to use the inspect module with
dynamically compiled code. The underlying issue is that at code-compile time
no sensible (PEP302 compliantly loaded) module can be constructed because this
is only known at exec-time but this is not part of the test tool API and is
done somewhere in user code.
Proposed fix: revert to r301 behaviour and add back "or getfile(object)" to the
first line of inspect.findsource()
