feat(sports): share the sports.py surface that is identical in all eight scoreboards - #515
Merged
Conversation
Nine scoreboards ship their own sports.py -- 41,326 lines. Comparing executable ASTs across the eight that share a lineage, 48 method bodies are byte-identical in every one: 1,007 lines carried eight times, so 8,056 lines that must be edited eight times to fix once. They are the parts with no sport in them: the selection and rotation engine (_round_robin_favorites, _favorites_first, _compose_selection, _check_ranking_coverage, _game_divisions, _normalise_quality), the font/colour/ date subsystem (_scale_headline_fonts, _scorebug_font, _resolve_font_size, _format_game_date, _font_color), and the switch-mode upcoming card (_draw_upcoming_center_switch). Nothing here knows what an inning is. Mixins rather than free functions: every one of these reads host state, so rewriting 48 bodies into free functions would be a rewrite rather than a move, and it is the move that keeps the renders identical. Three of the 48 are deliberately left in the plugins, because a byte-identical body is not automatically safe to move: - _get_timezone calls resolve_timezone, imported from a per-plugin module (hockey_timezone, soccer_timezone, ...). All eight of those differ -- each carries its own _WRITEBACK_FIXED_IN -- so hoisting the caller would silently bind every scoreboard to one plugin's copy. - _extract_game_details and _fetch_data are @AbstractMethod stubs. They are the sport contract; satisfying them from a mixin would let a plugin instantiate without implementing its own sport. _resolve_font_path went the other way: a module-level function, identical in all eight, that _scale_headline_fonts needs -- so it is inlined here. _schema_font_size needed a real change rather than a move. It located the plugin's config_schema.json with __file__, which here is src/common/, so the load failed silently, the cache stayed empty and every element fell back to an unsnapped size -- measured at 81% anti-aliased edges on a panel that should be pixel-crisp. It now recovers the plugin directory from the instance. Note that type(self).__module__ alone is not enough: SportsCore is an ABC, so a subclass built with type(name, bases, ns) -- which the plugins' own tests do -- reports its module as "abc". _plugin_dir walks the MRO past those synthetic classes to the first module sitting beside a config_schema.json. Worth recording: the 176 harness renders did NOT catch that regression. The plugin's own test_fonts_are_crisp.py did. Renders alone were not a sufficient gate here. Not merged with src/common/sports_card.py despite fourteen same-named twins. Only five are provably equivalent by source comparison; the other nine differ in ways inspection cannot settle, and a wrong guess silently changes what every scoreboard draws. That merge needs differential testing and is its own change.

…ract CodeRabbit found _QUALITY_CHOICES and _RANKING_COVERAGE_SECONDS read by _normalise_quality and _check_ranking_coverage but never defined on a mixin. Confirmed: both are declared by all eight scoreboards, so nothing fails today -- it would only have bitten the ninth plugin to adopt this, at runtime, mid-render. Both are identical everywhere, so they get defaults here; each plugin's own copy still shadows them. Auditing for others showed those two were the only ones, but also that the host-contract docstring was substantially incomplete: it listed 21 attributes where the mixins actually read about 40, and omitted five hooks (_is_favorite_game, _is_game_really_over, _is_ranked_game, _passes_other_filters, _get_timezone). The section is now derived from that audit rather than remembered. test_sports_shared.py covers what is genuinely new, not the moved bodies: - The contract itself. It parses the module for every ALL-CAPS `self.X` the mixins read and asserts each is defined, so the next omission fails here rather than in the field. - _plugin_dir, the only new logic in the move. Including the case that made it necessary: SportsCore is an ABC, so a subclass built with type(name, bases, ns) -- which the plugins' own tests build -- reports __module__ as "abc". The test asserts that precondition before asserting the walk steps past it. - The three SportsLive bodies. Hockey and lacrosse disable live mode in their harness fixtures, so the 176 renders never reach this path; testing the mixin directly means coverage no longer depends on which plugin happens to have a unit test. Two of those tests pin things that would otherwise be silently undone. SportsRecentSharedMixin does carry an __init__ -- SportsRecent.__init__ was one of the 48 byte-identical bodies. Its bare super() binds to where it is defined, now the mixin, so it only reaches the host because the mixin is listed first in the bases. One test proves the chain runs; the next proves that reversing the order silently skips the host constructor.
Codacy flagged five issues on this file. Three are unused imports: math, abc.abstractmethod and zoneinfo.ZoneInfo. Nothing in the module references any of them -- the timezone work goes through pytz, and the @AbstractMethod mention in the module docstring describes the two stubs that deliberately stayed behind in each plugin, not anything declared here. pyflakes agrees; all three are removed. The other two are "team_in is not callable" on the round-robin favourite matcher. That call is already guarded by callable(), so it cannot raise at runtime, but callable() is not a narrowing construct a static analyser follows: the name still carries the None from getattr's default. Normalising a non-callable to None and branching on `is None` gives the analyser a test it does understand, and keeps the guard. Behaviour is unchanged. _round_robin_favorites has no test coverage, so I exercised it directly on both paths -- a host with _team_in (id matching, the NRL case) and one without (abbreviation matching) -- across limits 1 to 4, and the selections are identical before and after. A host whose _team_in is present but not callable still falls back to abbreviation matching rather than raising. test/test_sports_shared.py: 27 passed. The 9 collection errors under `pytest test/ -k sport` reproduce identically on the unmodified branch and are not from this change. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…366) Forty-five method bodies in each of these eight sports.py files were byte-identical to the same forty-five in every other scoreboard: 1,007 lines per plugin, 8,056 duplicated in total. They now come from src.common.sports_shared (ChuckBuilds/LEDMatrix#515) and each class inherits the matching mixin. 8,321 lines removed. Three of the forty-eight identical bodies stayed behind on purpose, because a byte-identical body is not automatically safe to move: - _get_timezone binds resolve_timezone from a per-plugin module (hockey_timezone, soccer_timezone, ...). All eight of those files differ -- each carries its own _WRITEBACK_FIXED_IN -- so hoisting the caller would have silently bound every scoreboard to one plugin's copy. - _extract_game_details and _fetch_data are @AbstractMethod stubs. They are the sport contract; satisfying them from a mixin would let a plugin instantiate without implementing its own sport. Class constants are left in place rather than removed, so each plugin's own values still shadow the mixin's defaults. That matters for afl and basketball, which set _SCORE_PROBE_TEXT to "000-000"; the mixin's "00-00" is a default for future plugins, not a change to these. Test changes, all of them making tests exercise the real module rather than a stub: - Nineteen tests stubbed "src"/"src.common" as plain ModuleTypes, so the new import failed with "'src.common' is not a package". They now give those stubs a __path__ into the core, which lets genuine submodules resolve while the stubbed ones stay stubbed. Stubbing the mixins instead would have made every one of those tests pass against dummies -- which is how B5 shipped four of eight broken with every gate green. - soccer/test_schedule_horizon.py AST-parses sports.py looking for _get_weeks_data, which now lives in the core. It looks in both places; its assertions are about the body, which moved verbatim. Verification: all 176 safety-harness renders byte-identical to pristine main, 245 plugin tests pass, five repo gates pass. The one remaining fleet failure is 7-segment-clock/test_render_polarity.py, which fails identically on main and is fixed separately in #364. Versions are bumped above the sports_card/geometry branch rather than above main, since that branch lands first and already claims the next minor. Co-authored-by: Claude <noreply@anthropic.com>
