It may be None, indicating no particular context for the search. modname specifies a single module (not dotted) within the parent. fqname specifies the fully-qualified module name. This is a (potentially) dotted name from the "root" of the module namespace down to the modname. If there is no parent, then modname==fqname. This method should return None, or a 3-tuple. * If the module was not found, then None should be returned. * The first item of the 2- or 3-tuple should be the integer 0 or 1, specifying whether the module that was found is a package or not. * The second item is the code object for the module (it will be executed within the new module's namespace). This item can also be a fully-loaded module object (e.g. loaded from a shared lib). * The third item is a dictionary of name/value pairs that will be inserted into new module before the code object is executed. This is provided in case the module's code expects certain values (such as where the module was found). When the second item is a module object, then these names/values will be inserted *after* the module has been loaded/initialized. s get_code not implementedN( t RuntimeError( R R8 RS R3 ( ( s /usr/lib64/python2.7/imputil.pyRP r s ( R< RH RI RC R0 RK RQ RL RM R' RP ( ( ( s /usr/lib64/python2.7/imputil.pyR � s # % t ct os .pyc C s� t | d � j � } | r8 | d d k r8 | d } n t j | | d � } y t | t d � } Wn t k rw nn X| j d � | j t j d | � � t j | | � | j � | j d d � | j t j � � | j � | S( sN Compile (and cache) a Python source file.
