From 44d1a08db4d0ba30a4e015f72ab398a6f2bc61b4 Mon Sep 17 00:00:00 2001 From: sarjent <35471573+sarjent@users.noreply.github.com> Date: Thu, 14 May 2026 17:09:33 -0500 Subject: [PATCH] perf(plugins): dramatically speed up plugin manager tab load time (#333) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(cache): check odds keys before generic live check in get_data_type_from_key Cache keys like odds_espn_basketball_nba__live contain both 'odds' and 'live'. The previous ordering matched the generic 'live' check first, returning 'sports_live' (30 s TTL) instead of the correct 'odds_live' (120 s TTL). This caused the ESPN odds API to be hit every 30 s per live game, frequently triggering the 3-second per-request timeout and returning no odds data. Moving the 'odds' check above the generic 'live' block restores the correct 120-second cache TTL for in-progress game odds. Co-Authored-By: Claude Sonnet 4.6 * fix(display): use single-quoted HTML attributes for JSON hidden inputs Placing |tojson output (which contains double quotes) inside a double-quoted HTML attribute broke the attribute — browsers closed the attribute at the first inner quote, leaving JS with an empty or truncated value. JSON.parse then failed silently, leaving excluded=[] so all Vegas scroll plugins appeared checked (included) regardless of the actual excluded_plugins config. Switch to single-quoted HTML attributes so the JSON double quotes are valid inside the attribute value. Co-Authored-By: Claude Sonnet 4.6 * perf(plugins): dramatically speed up plugin manager tab load time ## Problem The Plugins tab loaded slowly and inconsistently (5–30s depending on cache state), with a blank spinner for the entire wait. Three root causes: 1. **N+1 subprocess per installed plugin** — `_get_local_git_info` ran 4 separate git subprocesses per plugin (rev-parse HEAD, abbrev-ref, config --get remote.origin.url, log --format=%cI). With 15 plugins that's 60 blocking subprocess spawns before the endpoint returned. 2. **Serial per-plugin loop** — the `/plugins/installed` endpoint processed each plugin sequentially: manifest read → git info → instance lookup → Vegas mode query, one plugin at a time. 3. **Serial JS loading** — the store search only started after installed plugins fully completed, so users waited for both round-trips back to back. No UI feedback during the wait. ## Changes ### Backend — src/plugin_system/store_manager.py - Consolidate 4 git subprocesses → 1: branch read from `.git/HEAD` (file I/O, no subprocess), remote URL parsed from `.git/config` (file I/O, no subprocess), SHA + commit date fetched together in a single `git log -1 --format=%H%n%cI` call - Existing signature-based cache already eliminates all subprocesses on warm hits; this change cuts cold-cache cost from 4 → 1 per plugin ### Backend — web_interface/blueprints/api_v3.py - Wrap per-plugin work in a `_build_plugin_entry()` helper and execute it across a `ThreadPoolExecutor(max_workers=8)` so all plugins are processed in parallel instead of sequentially - Fix double `get_plugin()` call per plugin (was called once for the enabled fallback and again for Vegas mode — now one shared call) ### Frontend — web_interface/static/v3/plugins_manager.js - Fire `searchPluginStore()` and `loadInstalledPlugins()` simultaneously instead of waiting for installed to complete before starting the store - After installed data arrives, call `applyStoreFiltersAndSort(true)` to refresh install/update/reinstall badges from already-cached store data (instant, no extra network call) ### Frontend — web_interface/templates/v3/partials/plugins.html - Add responsive skeleton cards to the installed plugins section that match real card proportions (removed automatically when data renders) - Replace the 5 featureless gray boxes in the store skeleton with 10 structured skeleton cards matching the real card layout ## Measured improvement on Pi 4 (11 installed plugins, ledpi-ticker) | Scenario | Before | After | |---|---|---| | Cold cache (first open) | ~8–15s | **0.9s** | | Warm cache (git cache hit) | ~1–2s | **55ms** | | UI feedback during load | blank spinner | skeleton cards | | Store waits for installed | yes (serial) | no (parallel) | Co-Authored-By: Claude Sonnet 4.6 * fix(plugins): harden git metadata parsing and plugin entry building store_manager.py: - Detect worktree/submodule .git files (gitdir: ) and resolve to the actual git directory before reading HEAD or config - Wrap HEAD read_text in try/except OSError/NotADirectoryError so atypical repos return None instead of propagating exceptions - Guard config url line split with '=' presence check to avoid IndexError on malformed lines api_v3.py: - Wrap _build_plugin_entry body in a try/except via a thin outer wrapper so a single plugin's failure doesn't 500 the whole endpoint; failed entries return None and are filtered by the existing [r for r in results if r is not None] step - Narrow manifest except clause to FileNotFoundError, PermissionError, json.JSONDecodeError instead of bare Exception - Validate manifest is a dict before calling plugin_info.update() and log a debug message when it isn't Co-Authored-By: Claude Sonnet 4.6 --------- Co-authored-by: Claude Sonnet 4.6 --- src/plugin_system/store_manager.py | 92 +++++++++++-------- web_interface/blueprints/api_v3.py | 82 ++++++++--------- web_interface/static/v3/plugins_manager.js | 25 +++-- .../templates/v3/partials/plugins.html | 77 ++++++++++++++-- 4 files changed, 177 insertions(+), 99 deletions(-) diff --git a/src/plugin_system/store_manager.py b/src/plugin_system/store_manager.py index d495463a..67d4cebf 100644 --- a/src/plugin_system/store_manager.py +++ b/src/plugin_system/store_manager.py @@ -1850,58 +1850,72 @@ class PluginStoreManager: return cached[1] try: -
