From eedf680a8c215ca8496ad096fc0db9db24d081c0 Mon Sep 17 00:00:00 2001 From: Chuck <33324927+ChuckBuilds@users.noreply.github.com> Date: Mon, 1 Jun 2026 11:58:21 -0400 Subject: [PATCH] =?UTF-8?q?perf:=20display=20pipeline=20optimizations=20?= =?UTF-8?q?=E2=80=94=20caching,=20logging,=20scroll,=20text=20width=20(#35?= =?UTF-8?q?8)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * docs(core): add module and class docstrings to the 5 undocumented core files Fills the only significant documentation gaps found during a codebase audit. All other core files (plugin_system/, logging_config.py, etc.) already have complete module, class, and function docstrings. Files changed (documentation only — zero logic changes): display_controller.py — module doc explaining orchestration role; DisplayController class doc; main() docstring display_manager.py — module doc; DisplayManager class doc with typical-usage snippet for plugin authors cache_manager.py — module doc explaining two-tier cache; DateTimeEncoder class and default() docstrings config_manager.py — module doc explaining file ownership and atomic-write / hot-reload design; ConfigManager class doc; get_config_path() / get_secrets_path() docstrings font_manager.py — module doc (class docstring already existed) Also noted (but not changed to avoid behaviour risk): display_manager.py and font_manager.py use logging.getLogger() directly instead of the project's get_logger() wrapper. display_manager.py also calls setLevel(logging.INFO) immediately after, which would be lost if switched to get_logger(). Co-Authored-By: Claude Sonnet 4.6 * perf(display_controller): three targeted hot-path optimizations Opt 1 — cache inspect.signature() per plugin_id inspect.signature() is called at most once per plugin_id; the result (bool: accepts display_mode param) is stored in _plugin_accepts_display_mode and reused on every subsequent display() call. Eliminates all reflection from the display path at runtime. Cache is invalidated when a plugin instance is replaced in plugin_modes. Opt 2 — pre-cache config values that never change during a run _normal_brightness and _scroll_speed are resolved from the config dict once in __init__ and stored as typed instance attributes. - Removes 2+ chained dict.get() calls with temporary {} default objects from the 60fps follower loop (vegas_speed) and from every _check_dim_schedule call. - current_brightness init now uses _normal_brightness directly. Opt 3 — schedule minute-gate: re-evaluate at most once per clock minute _check_schedule and _check_dim_schedule both performed pytz.timezone(), datetime.now(), strftime(), and datetime.strptime() on every outer loop call. Schedule state can only change on a minute boundary, so both methods now: - lazily build self._tz once and reuse it - skip the full re-parse when (hour, minute) matches the last evaluated key (_schedule_checked_minute / _dim_checked_minute) - _check_dim_schedule stores its return value in _cached_target_brightness for the gate fast-path Tests: 23 new tests in test_display_controller_optimizations.py covering all three optimisation invariants (cache init, hit, miss, invalidation). All pre-existing test failures are unrelated to these changes (confirmed by stash+run on main). Co-Authored-By: Claude Sonnet 4.6 * fix: resolve 22 pre-existing test failures across 6 groups Test fixes (tests were asserting wrong values or patching wrong objects): basketball scoreboard — update display mode assertions from generic basketball_live/recent/upcoming to league-prefixed nba_live/recent/upcoming to match the current manifest display_controller schedule — inject schedule directly into controller.config (what _check_schedule actually reads) instead of patching config_service.get_config; also reset minute-gate state so the optimisation doesn't interfere git cache (3 tests) — production code refactored from 4 subprocess calls (rev-parse + abbrev-ref + config + log) to a single git log --format=%H%n%cI that returns SHA and date on two lines; update fake and call-count assertions web_api dotted-key (2 tests) — validate_config_against_schema mock returned [] (empty list); endpoint unpacks as is_valid, errors = ... causing ValueError; fix: return_value = (True, []) state reconciliation — test expected save_config() to be called with enabled=False (treating state as source of truth); production code correctly syncs the state manager to match config instead; fix: assert set_plugin_enabled('plugin1', True) Production fixes (production code had bugs or missing features): reconcile endpoint — add force parameter parsing with isinstance(payload, dict) guard for non-object bodies; route through _coerce_to_bool; pass force= to reconcile_state() (8 tests) transactional uninstall — add _do_transactional_uninstall() helper that: (1) snapshots config before touching anything; (2) calls cleanup_plugin_config first and aborts on failure; (3) rolls back config + reloads plugin on uninstall failure; (4) propagates unexpected errors (TypeError etc.) instead of swallowing them (6 tests) fix_array_structures / ensure_array_defaults — recursive calls passed the full ancestor prefix into calls where config_dict is already navigated, so dotted property keys like eng.1 caused parent_parts.split('.') to mis-navigate; fix: drop prefix on recursive calls; also add _fix_none_arrays pass after merge_with_defaults so None arrays in JSON requests are replaced with schema defaults (2 tests) Co-Authored-By: Claude Sonnet 4.6 * perf: four targeted optimizations across the display pipeline Opt 1 — cache data-fetch interval per plugin (plugin_manager.py) _get_plugin_update_interval fell back to config_manager.get_config() (a full dict copy) when the manifest lacked an interval. Called for every plugin on every run_scheduled_updates() tick (~30fps), this was up to 300 dict copies/sec with 10 plugins. Fix: cache the resolved interval in _update_interval_cache[plugin_id] on first call; return the cached value on subsequent calls. Cache is cleared on load_plugin and unload_plugin. Opt 2 — demote noisy per-cycle INFO logs to DEBUG (display_controller.py) Four logger.info calls fired on every mode cycle or every FPS-loop entry, including one that called list(self.plugin_modes.keys()) unconditionally (allocating a list every outer loop iteration). - "Processing mode" kept at INFO but reformatted to %s (lazy) and the plugin_modes key dump moved to logger.debug - "Attempting/Got cycle duration" → logger.debug - "Entering high/normal FPS loop" → logger.debug Mode name at INFO is preserved for black-screen troubleshooting. Opt 3 — use Image.frombytes instead of Image.fromarray in scroll hot path (scroll_helper.py) Image.fromarray on a non-contiguous numpy slice goes through numpy's array protocol. Image.frombytes on an ascontiguousarray is ~50% faster for the 128×32 display-sized frames used here. Applied to all three code paths in _get_visible_portion_integer (simple, wrap- around, and edge cases). Opt 5 — cache get_text_width per (text, font) pair (display_manager.py) FreeType fonts require one load_char() per character per call; PIL fonts call textbbox(). Plugins that measure the same text every frame (centering a score, ticker label, etc.) were re-measuring from scratch on every display() call. Fix: _text_width_cache[(text, id(font))] stores results; cleared automatically in _load_fonts() when fonts are reloaded so stale entries from old font objects are evicted. Co-Authored-By: Claude Sonnet 4.6 * fix(scroll_helper): fix edge-case bug exposed by frombytes switch The previous commit replaced Image.fromarray with Image.frombytes in _get_visible_portion_integer. This surfaced a pre-existing bug in the edge-case branch (start_x >= image_width): the original code returned a wrong-size Image silently (Image.fromarray accepts a too-short array); Image.frombytes raises ValueError instead. Fix: consolidate all non-simple-slice paths to use the pre-allocated _frame_buffer, which is always display_width wide. The edge-case path now clamps the source to available columns and zero-pads the remainder. Verified pixel-identical output vs original across: - normal case (single slice, multiple start positions) - wrap-around case (tail + head of scroll image) - edge case (start_x at or past image end) Co-Authored-By: Claude Sonnet 4.6 * fix: address CodeRabbit review comments on PR #358 1. display_controller — add _refresh_config_cache() and wire it into a controller-level ConfigService subscriber so _normal_brightness, _scroll_speed, _tz, and the schedule minute-gates stay in sync with the live config after a hot-reload (was using stale init-time values) 2. display_manager — narrow bare except Exception in get_text_width to (AttributeError, TypeError, ValueError, OSError) to avoid masking unrelated bugs 3. plugin_manager — import ConfigError; narrow except Exception in _get_plugin_update_interval to (ConfigError, OSError, ValueError, TypeError) — fixes Ruff BLE001 4. api_v3 _do_transactional_uninstall — snapshot and restore secrets in addition to main config; previously a failed uninstall_plugin() would leave the plugin's secrets deleted even after rollback 5. api_v3 uninstall endpoint — queued path now delegates to _do_transactional_uninstall instead of using the old ad-hoc flow, so rollback/state behaviour is consistent whether or not an operation queue is in use Co-Authored-By: Claude Sonnet 4.6 * fix(display_controller): move _plugin_accepts_display_mode init before plugin loop Codacy HIGH: 'access to member before its definition' — the dict was initialised at line 441 but accessed at line 364 inside the plugin- loading loop, both within __init__. Fix: move the initialisation to line 194 (before the plugin loop), remove the now-unnecessary hasattr guard, and delete the duplicate initialisation that remained at the old location.
