#12868: Attaching a pyx file in the presence of __init__.py results in wrong
module
names
-------------------------+--------------------------------------------------
Reporter: SimonKing | Owner: jason
Type: defect | Status: new
Priority: major | Milestone: sage-5.1
Component: misc | Keywords:

-------------------------+--------------------------------------------------
Create a new folder (say, /home/simon/SAGE/work/tests/) and create a file
test.pyx with the content
{{{
class bla(type):
pass
}}}
Start sage, attach the file, and you will find something like
{{{
sage: attach test.pyx
Compiling ./test.pyx...
sage: bla.__module__
'sage: attach test.pyx
Compiling ./test.pyx...
sage: bla.__module__
'_home_simon_SAGE_work_tests_test_pyx_0'
}}}
Then, create an `__init__.py` file in the same folder. You will find
{{{
sage: attach test.pyx
Compiling ./test.pyx...
sage: bla.__module__
'_home_simon_SAGE_work_tests_test_pyx._home_simon_SAGE_work_tests_test_pyx_0'
sage: sys.modules.has_key(bla.__module__)
False
}}}
In fact, even if `__init__.py` is present, the module is still known under
the "short" name, but the class doesn't know about it:
{{{
sage: import _home_simon_SAGE_work_tests_test_pyx_0
sage: _home_simon_SAGE_work_tests_test_pyx_0.bla
<class
'_home_simon_SAGE_work_tests_test_pyx._home_simon_SAGE_work_tests_test_pyx_0.bla'>
}}}
Please change the component if you think that there is one that fits less
bad than "misc"...
