- Description:
- Blockbuster is a Python package designed to detect and prevent blocking calls
within an asynchronous event loop. It is particularly useful when executing
tests to ensure that your asynchronous code does not inadvertently call blocking
operations, which can lead to performance bottlenecks and unpredictable
behavior.
In Python, the asynchronous event loop allows for concurrent execution of tasks
without the need for multiple threads or processes. This is achieved by running
tasks cooperatively, where tasks yield control back to the event loop when they
are waiting for I/O operations or other long-running tasks to complete.
However, blocking calls, such as file I/O operations or certain networking
operations, can halt the entire event loop, preventing other tasks from running.
This can lead to increased latency and reduced performance, defeating the
purpose of using asynchronous programming.
The difficulty with blocking calls is that they are not always obvious,
especially when working with third-party libraries or legacy code. This is where
Blockbuster comes in: it helps you identify and eliminate blocking calls in your
codebase during testing, ensuring that your asynchronous code runs smoothly and
efficiently. It does this by wrapping common blocking functions and raising an
exception when they are called within an asynchronous context.
Notes:
- Blockbuster currently only detects asyncio event loops.
- Blockbuster is tested only with CPython. It may work with other Python
implementations if it's possible to monkey-patch the functions with setattr.
