Drop Python 3.8 support in 5 Pulsar-compatible packages
(job_metrics, tool_util, tool_util_models, util, objectstore)
and run pyupgrade --py310-plus on their source code.
- Bump requires-python from >=3.8 to >=3.10 in all 5 packages
- Remove Python 3.8 and 3.9 classifiers
- Remove ruff per-file-ignores for UP rules on these paths
- Remove backports.zoneinfo conditional dependency
- Remove pydyf<0.11 pin from conditional-requirements.txt
- Update Makefile pyupgrade target (remove PY38_PYUPGRADE_PATHS)
- Update CI workflow to test with Python 3.10 instead of 3.8
Clean up unused deprecated typing imports after pyupgrade
Remove now-unused typing imports (Dict, List, Optional, Set, Tuple,
Type, Union) that became dead after pyupgrade --py310-plus converted
annotations to use built-in types and | syntax.
Also run ruff check --fix --select=UP007,UP045 across the entire
codebase to convert remaining Optional[X] -> X | None and
Union[X, Y] -> X | Y patterns.
Enable ruff UP007/UP045 for Python 3.10 union syntax
Remove UP007 (Union[X,Y] -> X | Y) and UP045 (Optional[X] -> X | None)
from the ruff ignore list and convert all type aliases across the
codebase. These rules were deferred while Python 3.9 was supported;
requires-python is now >=3.10.
A custom script was used because neither ruff --fix nor
pyupgrade --py310-plus converts Optional[X]/Union[X,Y] in type alias
positions (e.g. X = Union[A, B]) — they only handle annotation
positions (e.g. def f(x: Optional[int])). All 167 violations were
module-level type aliases. A few edge cases were fixed manually:
single-element Union[X,], typing.Union qualified refs, runtime
Optional[type] calls, and Annotated[Optional[...]] pydantic fields.
Fix UP007 autofix regression with string forward reference type aliases
Commit fa6bd955a0 enabled ruff UP007/UP045 and auto-fixed
module-level type aliases using Union with string forward
references, producing invalid 'str | str' expressions.
This was a known ruff bug (charliermarsh/ruff#826) that has since
been fixed in later ruff versions, but this codebase was
converted before the fix was in place.
Revert to Union syntax and restore TYPE_CHECKING imports that
ruff's TCH rule cleaned up as a side effect when it thought the
forward references were unused.
Upgrade syntax using `pyupgrade --py36-plus` .
Manually drop several `six` imports.
Also:
- Remove broken pr_cache in scripts/bootstrap_history.py
- Fix broken prefix removal in lib/galaxy/tool_util/deps/mulled/mulled_build.py
- Allow specifying Python to use to create virtualenv using GALAXY_PYTHON
environment variable.
- Integrate Python support docs from https://galaxyproject.org/admin/python/
- Update virtualenv installation to use v16.7.9
