About opencensus-context

OpenCensus Runtime Context

|pypi|

.. |pypi| image:: https://badge.fury.io/py/opencensus-context.svg :target: https://pypi.org/project/opencensus-context/

The OpenCensus Runtime Context provides in-process context propagation. By default, thread local storage is used for Python 2.7, 3.4 and 3.5; contextvars is used for Python >= 3.6, which provides asyncio support.

Installation

This library is installed by default with opencensus, there is no need to install it explicitly.

Usage

In most cases context propagation happens automatically within a process, following the control flow of threads and asynchronous coroutines. The runtime context is a dictionary stored in a context variable <https://docs.python.org/3/library/contextvars.html> when available, and in thread local storage <https://docs.python.org/2/library/threading.html#threading.local> otherwise.

There are cases where you may want to propagate the context explicitly:

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Provides in-process context propagation for distributed tracing, using contextvars for Python 3.6+ and thread-local storage for earlier versions to enable automatic context flow across threads and async coroutines.

Low friction—pure Python wheel with only contextvars as a runtime dependency. However, the project is archived and unmaintained since August 2022 (1471 days ago), raising concerns about future compatibility and security updates.

Apache-2.0 is permissive and imposes no significant restrictions on use or redistribution, making it suitable for most commercial and open-source projects.

Usage

from opencensus.common.runtime_context import RuntimeContext
from threading import Thread

def work(name):
    print(RuntimeContext)

thread = Thread(
    target=RuntimeContext.with_current_context(work),
    args=('example',),
)
thread.start()
thread.join()

Package is archived and unmaintained; no active support or updates beyond August 2022.

Verdict: opencensus-context is a lightweight, dependency-minimal context propagation utility with permissive licensing, but its abandoned status (archived repository, no releases since August 2022) makes it risky for new projects. Suitable only if already locked into an existing opencensus deployment or if you can accept no upstream maintenance.

Needs verification

Whether contextvars backport is required for Python 2.7–3.5 support, or if those versions are no longer tested
Whether the archived repository will accept security patches or if a maintained fork exists
