| | 4 | == Introduction == |
| | 5 | |
| | 6 | As of June 2019, Sahana Eden is written for Python-2.7, but some tools (e.g. python-pip) will end their support for this Python version soon. Therefore, Sahana Eden must implement Python-3.6 as soon as possible. However, as most active deployments still run on Python-2.7, Sahana Eden must remain backwards-compatible for some time. |

| | 8 | == Stakeholders == |
| | 9 | |
| | 10 | - Deployers |
| | 11 | - Developers (both Sahana, and dependencies/libraries) |
| | 12 | |
| | 13 | == Requirements == |
| | 14 | |
| | 15 | - all Python code in Sahana Eden shall be Python-3.6+ |
| | 16 | - maintain Python-2.7 backwards-compatibility |
| | 17 | - provide framework support for common compatibility patterns |
| | 18 | - provide guideline (coding conventions) with common compatibility patterns |
| | 19 | - provide routine QA measures to verify compatibility of critical code with both 3.6 and 2.7 (review, CI testing) |
| | 20 | - update deployment tools to support Python-3.6+ |
| | 21 | - Python-3.6+ to be standard deployment option by the end of 2019 |
| | 22 | |
| | 23 | == Planned Implementation == |
| | 24 | |
| | 25 | - s3compat module to implement alternatives |
| | 26 | - refactoring of all Sahana Eden Python code according to: |
| | 27 | - [wiki:DeveloperGuidelines/Py_2_3 Developer Guideline for Python 2/3 compatibility] |
