``tornado.locks`` -- Synchronization primitives
|
|
===============================================
|
|
|
|
.. versionadded:: 4.2
|
|
|
|
Coordinate coroutines with synchronization primitives analogous to
|
|
those the standard library provides to threads. These classes are very
|
|
similar to those provided in the standard library's `asyncio package
|
|
<https://docs.python.org/3/library/asyncio-sync.html>`_.
|
|
|
|
.. warning::
|
|
|
|
Note that these primitives are not actually thread-safe and cannot be used in
|
|
place of those from the standard library--they are meant to coordinate Tornado
|
|
coroutines in a single-threaded app, not to protect shared objects in a
|
|
multithreaded app.
