From 494e8f83e9cf97f58719ce5cdfeeeeb6f18aa42a Mon Sep 17 00:00:00 2001 From: Algis Dumbris Date: Sun, 19 Apr 2026 07:14:27 +0300 Subject: [PATCH] feat(plugin): plugin framework + plugintest + demo plugin + integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the compile-in plugin system designed in spec 019: - internal/plugin/ (~1,300 LOC): * Tiny Plugin interface + 10 optional HasX capability sub-interfaces * Host struct with Logger / DB / Messenger / Channels / Attachments / Search / Secrets / Events / Config / DataDir / Tracer / Metrics / DefaultOwner / BaseURL * Registry with panic-on-duplicate, stability-level tracking, capability indexing (MCP tools, actions, panels, channel types, routes, event subscribers, CLI commands) * Migrator: per-plugin SHA-256-checksum'd migration chain, namespaced plugin__* table enforcement, idempotent re-apply * Three-phase lifecycle (Migrate → Init → Start) with panic-safe wrappers around every plugin call; failure per plugin isolated, core continues * YAML config loader that preserves unknown top-level keys on round-trip * Status store exposing /api/plugins/status JSON * Restart helpers (Noop + SignalRestarter); graceful reload is in-process for the demo - internal/plugin/plugintest/ (~345 LOC): * NopHost(t) with in-memory modernc.org/sqlite * Run(t, plugin) full-lifecycle smoke helper * Assertions: HasTool, HasAction, HasPanel, HasChannelType, HasMigration, PluginStarted, PluginFailed * ScopedSecrets that returns ErrSecretNotFound for cross-plugin reads (satisfies SC-006) - internal/plugins/demo/ (canonical showcase): * Plugin that exercises every HasX capability (migrations, actions, HTTP routes, web panel, lifecycle, config schema, stability) * Own SQL migration creating plugin_demo_notes * Embedded HTML panel that fetches notes via JS * 4 unit tests covering smoke, full capability registration, action handlers, and config-driven max_notes limit - cmd/plugindemo/ (~290 LOC): * Demo HTTP server wiring registry to chi * Mounts /api/plugins/status, /api/admin/plugins/{name}/{enable,disable}, /api/actions/{name}, /api/plugins//* (per-plugin REST), /ui/plugins// (per-plugin UI) * SIGHUP-triggered config reload + registry rebuild + mux swap * SIGTERM/SIGINT graceful shutdown - test/integration/ (~357 LOC, build-tag "integration"): * 6 end-to-end tests against a spawned plugindemo binary * Enable/disable round-trip with data preservation * SIGHUP reload timing (measured 41 ms — SC-008 target is 2 s) * Action-404 on disabled plugin, panel-404 on disabled plugin * REST endpoints + UI panel reachable Contract deviation: admin toggle endpoints moved from /api/plugins/{name}/{enable,disable} to /api/admin/plugins/{name}/{...} to avoid URL collision with chi per-plugin route mounts. rest.md updated. Scope deferred to next session (mechanical follow-ups): - Port internal/wiki/ to internal/plugins/wiki/ - Squash 26 migrations to schema/000_initial.sql - Backup scripts for live kubic instance - Remaining 9 plugin extractions - Boundary-lint static analyzer - Wire into cmd/synapbus/main.go All unit + integration tests green. Chrome UI smoke test passes. autonomous_summary.md carries the full verification record.
