With an interface that is intentionally similar to the [`multiprocessing.Pool`](https://docs.python.org/3/library/multiprocessing.html#module-multiprocessing.pool) class from the standard library, the `TaskPool` provides you such methods as `apply`, `map`, and `starmap` to execute coroutines concurrently as [`asyncio.Task`](https://docs.python.org/3/library/asyncio-task.html#task-object) objects. There is no limitation imposed on what kind of tasks can be run or in what combination, when new ones can be added, or when they can be cancelled. For a more streamlined use-case, the `SimpleTaskPool` provides an even more intuitive and simple interface at the cost of flexibility. If you need control over a task pool at runtime, you can launch an asynchronous `ControlServer` to be able to interface with the pool from an outside process or via a network, and stop/start tasks within the pool as you wish. ## Usage Generally speaking, a task is added to a pool by providing it with a coroutine function reference as well as the arguments for that function. Here is what that could look like in the most simplified form: ```python from asyncio_taskpool import SimpleTaskPool ... async def work(_foo, _bar): ... async def main(): pool = SimpleTaskPool(work, args=('xyz', 420)) pool.start(5) ... pool.stop(3) ... await pool.gather_and_close() ``` Since one of the main goals of `asyncio-taskpool` is to be able to start/stop tasks dynamically or "on-the-fly", _most_ of the associated methods are non-blocking _most_ of the time. A notable exception is the `gather_and_close` method for awaiting the return of all tasks in the pool. (It is essentially a glorified wrapper around the [`asyncio.gather`](https://docs.python.org/3/library/asyncio-task.html#asyncio.gather) function.) For working and fully documented demo scripts see [USAGE.md](usage/USAGE.md). ## Installation ```shell pip install asyncio-taskpool ``` ## Dependencies Python Version 3.8+, tested on Linux ## Testing Install [`coverage`](https://coverage.readthedocs.io/en/latest/) with `pip`, then execute the [`./coverage.sh`](coverage.sh) shell script to run all unit tests and save the coverage report. ## License `asyncio-taskpool` is licensed under the **GNU LGPL version 3.0** specifically.
