This makes it possible to use locals without a manager.

However it is not possible to release data held by proxies that way, one always has to retain a reference to the underlying local object in order to be able to release it. .. versionadded:: 0.6.1 N( t __release_local__( t local( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt release_local s t Localc B sM e Z d Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z RS( t __storage__t __ident_func__c C s* t j | d i � t j | d t � d S( NR R ( t objectt __setattr__R ( t self( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt __init__5 s c C s t | j j � � S( N( t iterR t items( R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt __iter__9 s c C s t | | � S( s Create a proxy for a name.( t LocalProxy( R t proxy( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt __call__< s c C s | j j | j � d � d S( N( R t popR t None( R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR @ s c C s= y | j | j � | SWn t k r8 t | � � n Xd S( N( R R t KeyErrort AttributeError( R t name( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt __getattr__C s c C sP | j � } | j } y | | | | <Wn" t k rK i | | 6| | <n Xd S( N( R R R ( R R t valuet identt storage( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR I s c C s< y | j | j � | =Wn t k r7 t | � � n Xd S( N( R R R R ( R R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt __delattr__Q s ( s __storage__s __ident_func__( t __name__t __module__t __slots__R R R R R R R ( ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR 2 s t LocalStackc B sq e Z d Z d � Z d � Z d � Z d � Z e e e � Z [ [ d � Z d � Z d � Z e d � � Z RS( s� This class works similar to a :class:`Local` but keeps a stack of objects instead.

When the stack is empty it will no longer be bound to the current context (and as such released). By calling the stack without arguments it returns a proxy that resolves to the topmost item on the stack. .. versionadded:: 0.6.1 c C s t � | _ d S( N( R t _local( R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR s s c C s | j j � d S( N( R$ R ( R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR v s c C s | j j S( N( R$ R ( R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt _get__ident_func__y s c C s t j | j d | � d S( NR ( R R R$ ( R R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt _set__ident_func__{ s c s � f d � } t | � S( Nc s( � j } | d k r$ t d � � n | S( Ns object unbound( t topR t RuntimeError( t rv( R ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt _lookup� s ( R ( R R* ( ( R s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR � s c C sE t | j d d � } | d k r4 g | j _ } n | j | � | S( s Pushes a new item to the stackt stackN( t getattrR$ R R+ t append( R t objR) ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyt push� s c C sZ t | j d d � } | d k r% d St | � d k rL t | j � | d S| j � Sd S( s} Removes the topmost item from the stack, will return the old value or `None` if the stack was already empty.

For that you need a local manager. You can pass a local manager multiple locals or add them later by appending them to `manager.locals`. Everytime the manager cleans up it, will clean up all the data left in the locals for this context. The `ident_func` parameter can be added to override the default ident function for the wrapped locals. .. versionchanged:: 0.6.1 Instead of a manager the :func:`release_local` function can be used as well. .. versionchanged:: 0.7 `ident_func` was added. c C s� | d k r g | _ n- t | t � r6 | g | _ n t | � | _ | d k r� | | _ x0 | j D] } t j | d | � qd Wn t | _ d S( NR ( R t localst isinstanceR t listt ident_funcR R R ( R R5 R8 R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR � s c C s | j � S( s� Return the context identifier the local objects use internally for this context.

Forwards all operations to a proxied object. The only operations not supported for forwarding are right handed operands and any kind of assignment. Example usage:: from werkzeug.local import Local l = Local() # these are proxies request = l('request') user = l('user') from werkzeug.local import LocalStack _response_local = LocalStack() # this is a proxy response = _response_local() Whenever something is bound to l.user / l.request the proxy objects will forward all operations. If no object is bound a :exc:`RuntimeError` will be raised. To create proxies to :class:`Local` or :class:`LocalStack` objects, call the object as shown above. If you want to have a proxy to an object looked up by a function, you can (as of Werkzeug 0.6.1) pass a function to the :class:`LocalProxy` constructor:: session = LocalProxy(lambda: get_current_request().session) .. versionchanged:: 0.6.1 The class can be instanciated with a callable as well now. t __localt __dict__R c C s* t j | d | � t j | d | � d S( Nt _LocalProxy__localR ( R R ( R R R ( ( s= /opt/imh-python/lib/python2.7/site-packages/werkzeug/local.pyR s c C s^ t | j d � s | j � Sy t | j | j � SWn$ t k rY t d | j � � n Xd S( s� Return the current object.
