polling2
Updated polling utility with many configurable options
Decision gist · record as of 2026-08-14
Yes, if you need a lightweight polling utility. The package has no dependencies, low install friction, and a permissive license. However, note that it is aging—last released in 2021 and not actively developed—so it is best suited for stable, simple polling tasks rather than projects requiring ongoing maintenance or new features.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with no runtime dependencies.
- Maintenance status is aging—last release was 2021-07-19 and the last commit 2026-01-11, so the package is stable but not actively developed.

What it is and what it does
Polling2 is a utility for repeatedly calling a function until it returns a desired result or a timeout is reached. Instead of writing custom retry loops with exception handling and timing logic, you pass a callable to polling2.poll() along with timeout and step parameters, and it handles the polling loop for you—returning the function's result when the condition is met or raising an exception if the timeout expires.
The package is useful in integration tests, waiting for external resources (files, API responses, locks), and any scenario where you need to retry an operation with configurable delays and timeouts. It's a fork of the original polling library, maintained to address issues the original project no longer handles.
Use it for
- Wait for an API endpoint to return a successful status code before proceeding in tests or deployment scripts.
- Poll for the existence or non-existence of a file on disk with a timeout to avoid indefinite hangs.
- Retry acquiring a resource lock or waiting for a thread to release a lock within a time limit.
- Check for completion of an asynchronous background task by polling a status function periodically.
