Name Resolution (DNS)¶
gevent includes support for a pluggable hostname resolution system.
Pluggable resolvers are (generally) intended to be cooperative.
This pluggable resolution system is used automatically when the system
is monkey patched
, and may be used manually
through the resolver attribute
of the
gevent.hub.Hub
or the corresponding methods in the
gevent.socket
module.
A resolver implements the 5 standandard functions from the
socket
module for resolving hostnames and addresses:
Configuration¶
gevent includes four implementations of resolvers, and applications
can provide their own implementation. By default, gevent uses
a threadpool
. This can
be customized
.
Please see the documentation for each resolver class to understand the relative performance and correctness tradeoffs.
