Summary

Architecturally freezes the legacy algorithm and reorganizes the test suite, then ships the reviewed contributor fixes as 9.1.0. Legacy output is verified byte-for-byte unchanged.

Structure

  • slugify/_legacy.py: the legacy pipeline, moved into a dedicated frozen module. Public slugify() is now a thin dispatcher — algorithm='legacy' (default) calls the frozen implementation; algorithm='modern' runs the modern pipeline.
  • tests/: suite reorganized. The original upstream legacy suite is preserved unchanged as tests/test_legacy.py, mirroring the code split, alongside tests/test_release.py. pyproject/MANIFEST.in/tox.ini updated to the tests/ layout.
  • DOJO.md/README: document the legacy-frozen policy; ask contributors not to open PRs that change legacy output.

Shipping in 9.1.0 (modern-only unless noted)

Verification

  • pytest tests: 116 passed, 1 skipped, 105 subtests
  • Frozen 2,688-case legacy differential passes; original pre-split test.py passes against current code
  • mypy clean; configured pycodestyle and flake8 pass

Move the legacy slug pipeline into a dedicated frozen module and make the
public slugify() a thin dispatcher: algorithm='legacy' (default) calls the
frozen _legacy implementation, algorithm='modern' runs the modern pipeline.
Modern-only up-front TypeError validation for bool/non-int max_length and
non-str separator lives in the modern path; legacy output is unchanged.

Move the test suite into tests/: the original upstream legacy suite becomes
the frozen tests/test_legacy.py (contents unchanged), mirroring the _legacy.py
code split, alongside tests/test_release.py and the add_uppercase test. Update
pyproject testpaths, MANIFEST.in, and tox commands to the tests/ layout.

Record that legacy is architecturally frozen (slugify/_legacy.py and
tests/test_legacy.py) and that all new work targets algorithm='modern'.
Add a contributor note in the README not to open PRs that change legacy
output.

Bump to 9.1.0. Modern-only: decode uppercase &#X..; hex references
(Rupayon Haldar, #195); preserve fitting post-replacement output during
truncation (emme1t, #193); up-front argument type validation (Jon Bailey,
#196). Fix add_uppercase_char atomicity (Cristian Ramirez, #194). Legacy
output unchanged.
