"""Infrastructure for server-side request handlers.
19
Interesting module attributes:
20
* The request_handlers registry maps verb names to SmartServerRequest
22
* The jail_info threading.local() object is used to prevent accidental
23
opening of BzrDirs outside of the backing transport, or any other
24
transports placed in jail_info.transports. The jail_info is reset on
25
every call into a request handler (which can happen an arbitrary number
26
of times during a request).
29
# XXX: The class names are a little confusing: the protocol will instantiate a
30
# SmartServerRequestHandler, whose dispatch_command method creates an instance
31
