asyncio-compatible timeout context manager.
|
||
|
|
|
||
|
|
|
||
|
|
Usage example
|
||
|
|
-------------
|
||
|
|
|
||
|
|
|
||
|
|
The context manager is useful in cases when you want to apply timeout
|
||
|
|
logic around block of code or in cases when ``asyncio.wait_for()`` is
|
||
|
|
not suitable. Also it's much faster than ``asyncio.wait_for()``
|
||
|
|
because ``timeout`` doesn't create a new task.
|
||
|
|
|
||
|
|
The ``timeout(timeout, *, loop=None)`` call returns a context manager
|
||
|
|
that cancels a block on *timeout* expiring::
|
||
|
|
|
||
|
|
async with timeout(1.5):
|
||
|
|
await inner()
|
||
|
|
|
||
|
|
1. If ``inner()`` is executed faster than in ``1.5`` seconds nothing
|
||
|
|
happens.
|
||
|
|
2. Otherwise ``inner()`` is cancelled internally by sending
|
||
|
|
``asyncio.CancelledError`` into but ``asyncio.TimeoutError`` is
|
||
|
|
raised outside of context manager scope.
|
||
|
|
|
||
|
|
*timeout* parameter could be ``None`` for skipping timeout functionality.
|
||
|
|
|
||
|
|
|
||
|
|
Context manager has ``.expired`` property for check if timeout happens
|
||
|
|
exactly in context manager::
|
||
|
|
|
||
|
|
async with timeout(1.5) as cm:
|
||
|
|
await inner()
|
||
|
|
print(cm.expired)
|
||
|
|
|
||
|
|
The property is ``True`` if ``inner()`` execution is cancelled by
|
||
|
|
timeout context manager.
|
||
|
|
|
||
|
|
If ``inner()`` call explicitly raises ``TimeoutError`` ``cm.expired``
|
||
|
|
is ``False``.

||

Installation
|
||
|
|
------------
|
||
|
|

||
|
|
::
|
||
|
|
|
||
|
|
$ pip install async-timeout
|
||
|
|
|
||
|
|
The library is Python 3 only!

------------------
|
||
|
|
|
||

||
|
|
|
||
|
|
3.0.0 (2018-05-05)
|
||
|
|
------------------
|
||
|
|
|
||
|
|
- Drop Python 3.4, the minimal supported version is Python 3.5.3
|
||
|
|
|
||
|
|
- Provide type annotations
|
||
|
|
|
||
|
|
2.0.1 (2018-03-13)
|
||
|
|
------------------
|
||
|
|
|
||
|
|
* Fix ``PendingDeprecationWarning`` on Python 3.7 (#33)
|
||
|
|
|
||
|
|
|
||
|
|
2.0.0 (2017-10-09)
|
||
|
|
------------------
|
||
|
|
|
||
|
|
* Changed `timeout <= 0` behaviour
|
||
|
|
|
||
|
|
* Backward incompatibility change, prior this version `0` was
|
||
|
|
shortcut for `None`
|
||
|
|
* when timeout <= 0 `TimeoutError` raised faster
|
||
|
|
|
||
|
|
1.4.0 (2017-09-09)
|
||
|
|
------------------
|
||
|
|
|
||
|
|
* Implement `remaining` property (#20)
|
||
|
|
|
||
|
|
* If timeout is not started yet or started unconstrained:
|
||
|
|
`remaining` is `None`
|
||
|
|
* If timeout is expired: `remaining` is `0.0`
|
||
|
|
* All others: roughly amount of time before `TimeoutError` is triggered
|
||
|
|
|
||
|
|
1.3.0 (2017-08-23)
|
||
|
|
------------------
|
||
|
|
|
||
|
|
* Don't suppress nested exception on timeout. Exception context points
|
||
|
|
on cancelled line with suspended `await` (#13)
|
||
|
|
|
||
|
|
* Introduce `.timeout` property (#16)
|
||
|
|
|
||
|
|
* Add methods for using as async context manager (#9)
|
||
|
|
|
||
|
|
1.2.1 (2017-05-02)
|
||
|
|

||
|
|
