chitralverma opened a new issue, #7816:
URL: https://github.com/apache/opendal/issues/7816
## Feature Description
Raise the minimum supported Python version for the `opendal` Python binding
from 3.10 to at least 3.12. Concretely:
- `bindings/python/pyproject.toml`: `requires-python = ">=3.10"` → `">=3.12"`
- Drop the dedicated cp310 wheel build leg and make the `abi3` (currently
`abi3-py311`) wheel the single non-free-threaded artifact, bumped to
`abi3-py312`. (Free-threaded builds, which landed in Python 3.13, stay
as-is:
`3.13t`, `3.14t`.)
- Update CI to stop testing on 3.10/3.11, thereby dropping support for them.
## Problem and Solution
**Problem**
Python release/EOL timeline (from https://endoflife.date/python):
| Version | Released | EOL |
| ------- | -------- | --- |
| 3.9 | 2020-10 | 2025-10-31 (past) |
| 3.10 | 2021-10 | 2026-10-31 |
| 3.11 | 2022-10 | 2027-10-31 |
| 3.12 | 2023-10 | 2028-10-31 |
| 3.13 | 2024-10 | 2029-10-31 |
The binding's declared floor (`>=3.10`) targets versions that are at or near
end of life, and keeping 3.10 carries concrete maintenance overhead:
- The abi3 floor is already `pyo3/abi3-py311` (`bindings/python/Cargo.toml`),
with the standing comment *"we build cp311-abi3 and cp310 wheels now, move
this to pyo3 after we drop cp310."* 3.10 therefore needs a **separate,
non-abi3 wheel** in `release_python.yml` (`-i python3.10`) in addition to
the
abi3-py311 wheel — an extra build/release leg solely for the oldest
interpreter.
**Solution**
Bump to `>=3.12` and consolidate the wheel matrix:
- One abi3 wheel (`abi3-py312`) covering 3.12+, plus the existing
free-threaded
builds (3.13t, 3.14t).
- Remove the cp310 build leg and the "drop cp310" FIXME.
- Update `requires-python`, CI test interpreters (currently `python3.10` in
`test_behavior_binding_python.yml` and `python3.11` in
`ci_bindings_python.yml`), and any `Programming Language :: Python`
metadata.
Benefits:
- Fewer wheels to build/test/publish per release; simpler matrix.
- Drops interpreters that are at or near EOL.
- Lets the binding use 3.12-era language/stdlib features without guards.
## Additional Context
This surfaced while investigating the Python binding's stub generation, but
it
is independent of that work and warrants its own change.
## Are you willing to contribute?
Yes, I can raise a PR for this.
