This allows Python code to play nicely with non-filesystem based PEP 302 importers when locating support scripts as well as when importing modules. i����N( t read_code( t get_loadert run_modulet run_patht _TempModulec B s) e Z d Z d � Z d � Z d � Z RS( sC Temporarily replace a module in sys.modules with an empty namespacec C s( | | _ t j | � | _ g | _ d S( N( t mod_namet impt new_modulet modulet _saved_module( t selfR ( ( s /usr/lib/python2.7/runpy.pyt __init__ s c C sL | j } y | j j t j | � Wn t k r7 n X| j t j | <| S( N( R R t appendt syst modulest KeyErrorR ( R R ( ( s /usr/lib/python2.7/runpy.pyt __enter__ s c G s= | j r# | j d t j | j <n t j | j =g | _ d S( Ni ( R R R R ( R t args( ( s /usr/lib/python2.7/runpy.pyt __exit__( s ( t __name__t __module__t __doc__R R R ( ( ( s /usr/lib/python2.7/runpy.pyR s t _ModifiedArgv0c B s# e Z d � Z d � Z d � Z RS( c C s | | _ t � | _ | _ d S( N( t valuet objectt _saved_valuet _sentinel( R R ( ( s /usr/lib/python2.7/runpy.pyR 0 s c C sE | j | j k r! t d � � n t j d | _ | j t j d <d S( Ns Already preserving saved valuei ( R R t RuntimeErrorR t argvR ( R ( ( s /usr/lib/python2.7/runpy.pyR 4 s c G s | j | _ | j t j d <d S( Ni ( R R R R R ( R R ( ( s /usr/lib/python2.7/runpy.pyR : s ( R R R R R ( ( ( s /usr/lib/python2.7/runpy.pyR / s c B sJ | d k r | j | � n | j d | d | d | d | � | | U| S( s) Helper to run code in nominated namespaceR t __file__t __loader__t __package__N( t Nonet update( t codet run_globalst init_globalsR t mod_fnamet mod_loadert pkg_name( ( s /usr/lib/python2.7/runpy.pyt _run_code> s c C sZ t | � �B } t | � �- | j j } t | | | | | | | � Wd QXWd QX| j � S( s5 Helper to run code in new namespace with sys modifiedN( R R R t __dict__R( t copy( R" R$ R R% R& R' t temp_modulet mod_globals( ( s /usr/lib/python2.7/runpy.pyt _run_module_codeK s c C s= x6 d D]. } t | | d � } | d k r | | � Sq Wd S( Nt get_filenamet _get_filename( R.
