Hi,
when starting pypy-c, I get some extension module code executed before that
module is imported.
The code in question is in pypy/module/cppyy/pythonify.py:
gbl = make_cppnamespace(None, "::", None, False) # global C++ namespace
gbl.__doc__ = "Global C++ namespace."
sys.modules['cppyy.gbl'] = gbl
This code is not rpython code. The module is first mentioned in the
__init__.py of cppyy:
appleveldefs = {
'gbl' : 'pythonify.gbl',
'load_reflection_info' : 'pythonify.load_reflection_info',
'add_pythonization' : 'pythonify.add_pythonization',
}
How can I prevent that code from being executed at startup, i.e. have it
deferred all the way until "import cppyy"?
The use case is as follows: I have a prototype where I load the Reflex
library (and associated C-API) at run-time, using _cffi_backend. That way,
it is no longer necessary to link pypy-c with libReflex.so. I can handle a
missing .so silently, but would prefer to raise an ImportError. However,
for that to work, I need to make sure nothing of the module gets touched
until it's imported, so that the error is reported at the right time.
Thanks,
Wim
