Some child of the current node had a free reference to name. When the child was processed, it was labelled a free variable. Now that all its enclosing scope have been processed, the name is known to be a global or builtin. So walk back down the child chain and set the name to be global rather than free.

Propagate assignment flag down to child nodes. The Assign node doesn't itself contains the variables being assigned to. Instead, the children in node.nodes are visited with the assign flag set to true. When the names occur in those nodes, they are marked as defs. Some names that occur in an assignment target are not bound by the assignment, e.g. a name occurring inside a slice. The visitor handles these nodes specially; they do not propagate the assign flag to their children. i N( t nodesRJ RY ( R RK RL RU ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitAssign[ s i c C s | j | j � d S( N( R R ( R RK RL R\ ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitAssNamel s c C s | j | j | d � d S( Ni ( RJ RY ( R RK RL R\ ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitAssAttro s c C sA | j | j | d � x$ | j D] } | j | | d � q Wd S( Ni ( RJ RY t subs( R RK RL R\ RU ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitSubscriptr s c C s^ | j | j | d � | j r8 | j | j | d � n | j rZ | j | j | d � n d S( Ni ( RJ RY t lowert upper( R RK RL R\ ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitSlicew s c C sX | j | j | � t | j t j � rA | j | j | d � n | j | j | � d S( Ni ( RJ RK R6 R t NameRY ( R RK RL ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitAugAssign~ s c C s� xv | j D]k \ } } t | t j � rU t | j � | j k rU | j sR q qR qU n | j | | � | j | | � q W| j r� | j | j | � n d S( N( t testsR6 R t ConstRe t valuet _const_typesRJ Rq ( R RK RL Ra Rp ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitIf� s c C s d | _ | j | j | � d S( Ni ( R RJ R� ( R RK RL ( ( s& /usr/lib/python2.7/compiler/symbols.pyt visitYield� s ( R R= R RM t visitExpressionRV RW R[ R` Rb Rd RP RS Rm Rn Rr Ru Rx Ry R{ R| R} R R� R� Rf t StringTypet IntTypet FloatTypeR� R� R� ( ( ( s& /usr/lib/python2.7/compiler/symbols.pyRH � s4 c C s t | � t | � k S( N( t sorted( t l1t l2( ( s& /usr/lib/python2.7/compiler/symbols.pyt list_eq� s t __main__( t parseFilet walkc C sT g g | j � D] } | j � ^ q D]* } | j d � pG | j d � s& | ^ q& S( Ns _[Rv ( t get_symbolst get_namet startswith( t symst s( ( s& /usr/lib/python2.7/compiler/symbols.pyR' � s ,i t exect oopst skippingi ( ( (6 Ri t compilerR t compiler.constsR R R R R R t compiler.miscR Rf R- t MANGLE_LENR R> R8 RA RD R7 RH R� R R� R� t symtableR' t argvt filet opent ft readt buft closeR� t mod_namest treeR� RI t names2R� t exitR& R$ t valuesR� t is_namespaceR; R R� t lR t get_namespace( ( ( s& /usr/lib/python2.7/compiler/symbols.pyt <module> sj . � � !
