|
|
A resolver that directly uses the system's resolver functions.
|

|
|
.. caution::
|
|
|
|
This resolver is *not* cooperative.
|
|
|
|
This resolver has the lowest overhead of any resolver and
|
|
typically approaches the speed of the unmodified :mod:`socket`
|
|
functions. However, it is not cooperative, so if name resolution
|
|
blocks, the entire thread and all its greenlets will be blocked.
|
|
|
|
This can be useful during debugging, or it may be a good choice if
|
|
your operating system provides a good caching resolver (such as
|
|
macOS's Directory Services) that is usually very fast and
|
|
functionally non-blocking.
|
|
|
|
.. versionchanged:: 1.3a2

This was previously undocumented and existed in :mod:`gevent.socket`.
