Migrating a (variant of a) naming subthread from python-ideas over to
here, does the following sound plausible to anyone else?:
ContextLocal - read/write access API (via get()/set() methods)
ContextLocalNamespace - active mapping that CL.get()/set() manipulates
ExecutionContext - current stack of context local namespaces
Building a threading.local() style helper API would then look something like:
class ContextLocals:
def __init__(self, key_prefix):
self._key_prefix = key_prefix
def __getattr__(self, attr):
debugging_name = "{}.{}".format(self._key_prefix, attr)
self.__dict__[attr] = new_local =
sys.new_context_local(debugging_name)
return new_local
def __setattr__(self, attr, value):
getattr(self, attr).set(value)
def __delattr__(self, attr):
getattr(self, attr).set(None)
my_state = ContextLocals(__name__)
Cheers,
Nick.
