Require Python 3.9+, SPDX license metadata, psycodict.__version__ - #121
Merged
Conversation
Three packaging changes for 1.0, taken together because they interlock:
- requires-python >= 3.9 (3.8 has been end-of-life since October 2024).
The unit matrix drops 3.8 and the "oldest supported pair" database row
becomes py3.9/PG13; ruff's target-version moves to py39.
- license = "GPL-2.0-or-later" (PEP 639 SPDX expression), replacing the
free-text {text = "GPL v2+"}. The wheel now carries a proper
License-Expression field. This needs setuptools >= 77, which is what
previously kept it out: on py3.8, pip resolves setuptools 75.x, which
rejects the string form. With the 3.9 floor the workaround disappears;
build-system pins setuptools>=77 (wheel is no longer needed there).
- psycodict.__version__, the single source of truth: pyproject declares
version dynamic and reads the literal via [tool.setuptools.dynamic], so
the attribute also works from an uninstalled checkout (which is how
LMFDB runs psycodict today).
Verified: build + twine check --strict pass; wheel METADATA shows
Metadata-Version 2.4, License-Expression GPL-2.0-or-later,
Requires-Python >=3.9; installed psycodict.__version__ matches
importlib.metadata.version; database-free suite 326 passed; ruff clean.

Python 3.14 joins the unit matrix, and {py3.14, PG18} becomes the
matrix's newest-pair corner, per the comment asking for a new row when
a PostgreSQL major is released.

Rebased onto main, which absorbed everything this PR used to anticipate; the reconciliation: - Version: 1.0.0 is now set in psycodict.__init__.__version__, the single source of truth roed314#121 established -- pyproject keeps main's dynamic version, SPDX license string and >=3.9 floor, and this PR's classifiers drop the License:: entry (setuptools >= 77 rejects it next to an SPDX string) and the 3.8 entry. - README: the rewrite now carries the Versioning.md pointer (roed314#123) in its Documentation list, which switches to relative links -- on the Sphinx site (roed314#122) those resolve to the copied guide pages, and they still render on GitHub; CHANGELOG and LICENSE stay absolute since neither is on the site. Supported Python is 3.9+; blob/master URLs become blob/main. - CHANGELOG: entries for the late wave -- sum/random honoring saving (roed314#118) and the 3.9 floor (roed314#121) under breaking changes; the docs site (roed314#122), Versioning.md/CONTRIBUTING/SECURITY and __version__ (roed314#121) under added; reload metafile+resort (roed314#114), update_from_file stats publication (roed314#115), copy_dumps delimiter escaping (roed314#116) under fixed; config.ini untracking (roed314#120), this release workflow and CITATION.cff (roed314#124) under infrastructure. - release.yml: the flow notes now say bump __init__.__version__ and merge to main. - Fixes the docs build on main, broken by the roed314#119 x roed314#122 crossing (roed314#119 merged after roed314#122's last CI run): the Configuration docstring's nested defaults list needed blank lines to be valid RST under autodoc, and the README's relative LICENSE link had no target on the site. Suite 857 passed / 36 skipped; ruff clean; sphinx -W clean; python -m build + twine check --strict pass with Version 1.0.0, License-Expression GPL-2.0-or-later, Requires-Python >=3.9 and no License classifier in the wheel metadata.

Three packaging changes for 1.0, in one PR because they interlock (the 3.9 floor is what unlocks the license fix):
Python >= 3.9
3.8 has been EOL since October 2024, and 1.0 is the natural moment to set the floor — raising it later is a compatibility break. CI: the unit matrix drops 3.8; the database matrix's "oldest supported pair" row becomes
{py3.9, PG13}.[tool.ruff] target-versionmoves topy39.SPDX license expression
license = "GPL-2.0-or-later"(PEP 639), replacing free-text{text = "GPL v2+"}. The wheel now carries a realLicense-Expressionfield (Metadata-Version 2.4). This form needs setuptools >= 77, which is exactly what kept it out before: py3.8's pip resolves setuptools 75.x, which rejects it. With the floor at 3.9 the workaround disappears;build-systemnow pinssetuptools>=77(and dropswheel, unneeded with modern setuptools).Note for #113: with the string form, setuptools >= 77 errors if a
License ::trove classifier is also present — the release branch should not add one, and can drop its{text = "GPL-2.0-or-later"}table-form workaround; this supersedes it.psycodict.__version__Single source of truth in
psycodict/__init__.py; pyproject declaresdynamic = ["version"]and reads the literal via[tool.setuptools.dynamic](AST extraction — no import, so no psycopg needed at build time). Works from an uninstalled checkout too, which is how LMFDB runs psycodict today.Note for #113: the release becomes "bump
__version__in__init__.pyto1.0.0" — the staticversion =line in pyproject is gone.Verification
