| # PIP-155: Drop support for Python2 |
| |
| Python 2.x has been deprecated for many years now and it was officially end-of-lifed 2.5 years ago (https://www.python.org/doc/sunset-python-2/). |
| |
| We have well reached the point by which we need to drop Python 2.7 compatibility for Pulsar client and for Pulsar functions. |
| |
| Based on Python end-of-life policies, there are 4 versions of Python that are currently supported: 3.7, 3.8, 3.9 and 3.10. https://endoflife.date/python |
| |
| That gives a 5 years support schedule from release to EoL. |
| |
| ## Goal |
| |
| Support only the last 4 Python releases Pulsar client and for Pulsar functions, currently 3.7, 3.8, 3.9 and 3.10. Once 3.7 reaches end-of-life, it will be dropped by Pulsar too. |
| |
| This policy will be also applied to the Pulsar patch releases which will stop providing Python wheel files for the deprecated versions. |
| |
| ## API Changes |
| |
| No changes at this time, though Pulsar Python client library will be now free to use Python3 specific syntaxes and libraries. |
| |
| ## Changes |
| |
| 1. Switch the CI build to run Python client lib tests with Python3 |
| 2. Switch integration tests to use Python3 |
| 3. Stop building and distributing wheel files for Python 2.7 |
