ChuckBuildsandClaude Opus 5	094090d138	fix(display): consume the reconcile request before serving it ... Addresses the second review finding: a lost update on _pending_plugin_reconcile. The flag was cleared after a successful reconcile. Reconcile has already read its config by that point, so a config change arriving mid-flight set a flag that the trailing clear then erased -- a request that was never served, and the newest config never reconciled. That is the same "my save did nothing" symptom this PR exists to remove, so leaving it would have undercut the fix. Consume the request before running it instead, and re-arm only on a retryable failure. A change that lands during reconcile now stays set and is picked up on the next pass. The per-frame read stays lock-free. It is a fast path that can only produce a false negative -- the watcher setting the flag just after it is read is seen on the next iteration -- never a false positive that loses a request. The lock is taken only when a reconcile is actually pending or a config change arrives. Extracted _service_pending_reconcile() so the sequence is testable rather than buried in run()'s loop; the review asked for a regression test that invokes the subscriber during reconciliation, which is not reachable otherwise. Tests: 4 new, covering a request racing in mid-reconcile, the quiet success, the retryable-failure re-arm, and not reconciling when nothing is pending. Two of them fail against the previous clear-after-success semantics.

ChuckBuildsandClaude Opus 5	7156d31491	fix(display): snapshot the plugin mappings under their locks ... Addresses the review finding on the cross-thread reads. _enabled_plugin_not_running runs on the config-watcher thread and read two mappings the render thread mutates. Catching RuntimeError was not a fix: it turned a torn read into a coin flip between an unnecessary discovery scan and a missed retry, which is the bug this PR exists to remove. Both reads are now snapshots taken under the lock that guards their writes: - plugin_manifests via a new PluginManager.discovered_plugin_ids(), which copies the ids while holding the existing _discovery_lock. Discovery rebuilds that mapping entry by entry, so an unsynchronised reader can see it half-populated. - plugin_display_modes under a new controller lock, taken at the only two sites that mutate it (_register_loaded_plugin / _unregister_plugin). The locks are never nested -- each snapshot is taken and released before the next -- so this cannot deadlock against discovery, which holds _discovery_lock while it rebuilds. No cost on the per-frame path. Both mutation sites run during reconcile, which is rare, and every hot-path read of plugin_display_modes is on the render thread itself, same thread as the writes, so those stay lock-free. Tests: the accessor returns a snapshot rather than a live view, and actually takes the discovery lock (proved from a second thread, since an RLock is reentrant on the owning one) so a later refactor cannot quietly drop it.

ChuckBuildsandClaude Opus 5	4143aa958c	fix(display): retry a plugin that is enabled but failed to load ... A plugin whose validate_config() returns False is treated as a hard load failure. The API then reports enabled=true, loaded=false, error=null: the plugin is simply absent, with nothing saying why. hockey-scoreboard sat in that state on a live rig for four days. The recovery path existed but could not be reached. _reconcile_enabled_plugins computes to_add = desired - current, and a plugin that failed to load is never in current, so it stays in to_add and would be retried. But the reconcile is queued by _enabled_set_changed(), which compares only top-level `enabled` flags -- and the edit that actually fixes such a plugin (enabling a league, filling in an API key) is nested inside the plugin's own config section. No top-level flag changes, so no reconcile is queued, and the save that should have fixed it does nothing. Only toggling some unrelated plugin -- which does change a top-level flag -- queues the global reconcile that recovers it. Add a second gate: queue a reconcile when a discovered plugin is enabled in config but absent from the running set. It is deliberately narrow rather than "reconcile on any config change". Reconcile calls discover_plugins(), a ~39-manifest filesystem scan, and it runs on the render thread; doing that on every config save would trade this bug for a frame hitch. Gating on plugin_manifests also keeps non-plugin sections that carry their own `enabled` flag (schedule, display) from queueing a reconcile they can never satisfy. In the steady state -- every enabled plugin loaded -- the new check is False and costs nothing. The same valid-but-unconfigured => hard-fail shape still exists in text-display, youtube-stats, birdnet-go, ledmatrix-flights and mqtt-notifications; this makes all of them recoverable without a restart.

3 people	7a6bad29fe	feat(display-controller): hot-reload plugin enable/disable without a restart (#374) ... * feat(display-controller): hot-reload plugin enable/disable without a restart Enabling or disabling a plugin in config previously required restarting the display service: the plugin list and available_modes were built once at init and the run loop never revisited them. (Per-plugin config *values* already hot-reloaded; only the enabled set was restart-only.) Now the controller reconciles its running plugins against the config's enabled set whenever that set changes: - The ConfigService watcher thread only sets a `_pending_plugin_reconcile` flag (via a cheap enabled-set diff). It never mutates loop state. - The run loop applies the reconcile on its own thread (top of each iteration, deferred while on-demand is active), so loading/unloading and rebuilding available_modes can't race with rendering. - `_reconcile_enabled_plugins` diffs desired vs running plugins, unloads the removed ones (cleanup + on_disable + config-unsubscribe via the new `_unregister_plugin`) and loads the added ones, then clamps the rotation index so the current mode stays valid. The per-plugin registration done at startup is extracted into `_register_loaded_plugin` and reused by the live-enable path so both build identical state. Extracting it also fixes a latent late-binding bug: the per-plugin config-change callbacks were closures over the loop variable, so every plugin's callback targeted the last-loaded instance; each now binds its own id/instance. Adds test/test_display_controller_plugin_toggle.py covering live enable, live disable, index clamping, no-op when unchanged, and the enabled-set diff. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(display-controller): don't exit on empty available_modes, guard rotation modulo Hot-reload means available_modes can legitimately be empty at startup (no plugins enabled yet) and become non-empty later via the web UI, or vice versa mid-run. Fix four issues found reviewing this PR: - run() exited the process entirely when available_modes was empty at startup instead of idling, permanently defeating the point of live enable/disable for anyone who starts with zero plugins enabled. - The mode-rotation step divided by len(available_modes) unconditionally, raising ZeroDivisionError if the last enabled plugin is disabled between frames. - _reconcile_enabled_plugins() called .get('enabled', False) on a config section without checking it was a dict first, raising AttributeError on a malformed config value. - Minor: pop the config-change callback only after attempting to unsubscribe it, and log the exception in the config-read fallback instead of swallowing it silently. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * fix(display-controller): address review findings on the hot-reload PR - Idle-wait tick was a fixed 30s sleep, delaying pickup of a plugin enabled via the web UI while no modes were active. Shortened to ~1s so it's roughly as responsive as the per-frame check once modes exist. - _unregister_plugin popped the config-change callback from _plugin_config_callbacks even when config_service.unsubscribe() raised, losing the only reference to it. Now only pops on a successful unsubscribe. - _pending_plugin_reconcile was cleared before _reconcile_enabled_plugins() ran, so a retryable failure (e.g. plugin discovery erroring) silently dropped the enable/disable request. _reconcile_enabled_plugins() now returns True/False and the caller only clears the flag on True. - Added a warning log for the malformed-config case (a plugin's config section present but not a dict) so it's actually visible, and updated the existing test to assert it via caplog. Left the broad `except Exception` around config_service.unsubscribe() as Exception -- the current implementation is a simple lock+dict/list op that doesn't document or realistically raise a narrower type, so this is a defensive catch-all, not user error handling.
