From 57441df677ed074a363a115fb0cced59503caa21 Mon Sep 17 00:00:00 2001 From: Agent Zero Date: Wed, 26 Aug 2026 01:06:23 +0200 Subject: [PATCH] =?UTF-8?q?feat(f3):=20Gate-F-Pflichttest=20bestanden=20?= =?UTF-8?q?=E2=80=94=20Minimal-Plugin=20NUR=20aus=20dem=20Guide=20gebaut?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Der Pflichttest (Guide-Kapitel 29.1 verbatim nachgebaut) deckte 3 echte Guide-Luecken auf und wurde erst nach deren Behebung gruen: (1) __init__.py fehlte im Beispiel: discover_builtins scannt das Paket-Namespace und findet Klassen die nur in plugin.py leben nie. (2) Route brauchte vollen Pfad: main.py mountet Plugin-Router OHNE Prefix — leerer Route-Pfad wirft Prefix-and-path-cannot-be-both-empty. (3) Plugin-Routen werden dynamisch dispatched: sie erscheinen NIE in app.routes. Alle 3 Luecken sind jetzt in Kapitel 29.1 mit Warnhinweis dokumentiert; tests/test_gate_f_minimal_example.py beweist dauerhaft dass ein Guide-faehiges Plugin funktioniert. Beweise: Gate-F-Suite 4/4 gruen; ruff clean; Cross-Plugin-Scan sauber. --- .../builtins/minimal_example/__init__.py | 9 ++ .../builtins/minimal_example/plugin.py | 22 ++++ .../builtins/minimal_example/routes.py | 15 +++ docs/plugin-development-guide.md | 29 ++++- tests/test_gate_f_minimal_example.py | 106 ++++++++++++++++++ 5 files changed, 179 insertions(+), 2 deletions(-) create mode 100644 app/plugins/builtins/minimal_example/__init__.py create mode 100644 app/plugins/builtins/minimal_example/plugin.py create mode 100644 app/plugins/builtins/minimal_example/routes.py create mode 100644 tests/test_gate_f_minimal_example.py diff --git a/app/plugins/builtins/minimal_example/__init__.py b/app/plugins/builtins/minimal_example/__init__.py new file mode 100644 index 0000000..d9e3199 --- /dev/null +++ b/app/plugins/builtins/minimal_example/__init__.py @@ -0,0 +1,9 @@ +"""Minimal Example plugin package. + +Re-export the plugin class so ``discover_builtins`` finds it when scanning +the builtins package namespace (see guide chapter 29.1). +""" + +from app.plugins.builtins.minimal_example.plugin import MinimalExamplePlugin + +__all__ = ["MinimalExamplePlugin"] diff --git a/app/plugins/builtins/minimal_example/plugin.py b/app/plugins/builtins/minimal_example/plugin.py new file mode 100644 index 0000000..5d46f02 --- /dev/null +++ b/app/plugins/builtins/minimal_example/plugin.py @@ -0,0 +1,22 @@ +from app.plugins.base import BasePlugin +from app.plugins.manifest import PluginManifest, PluginRouteDef + + +class MinimalExamplePlugin(BasePlugin): + manifest = PluginManifest( + name="minimal_example", + version="1.0.0", + display_name="Minimal Example", + description="A minimal example plugin.", + dependencies=[], + routes=[ + PluginRouteDef( + path="/api/v1/minimal-example", + module="app.plugins.builtins.minimal_example.routes", + router_attr="router", + ), + ], + events=[], + migrations=[], + permissions=["minimal_example:read"], + ) diff --git a/app/plugins/builtins/minimal_example/routes.py b/app/plugins/builtins/minimal_example/routes.py new file mode 100644 index 0000000..f7468b2 --- /dev/null +++ b/app/plugins/builtins/minimal_example/routes.py @@ -0,0 +1,15 @@ +from fastapi import APIRouter, Depends + +from app.deps import get_current_user, require_permission + +# NOTE: main.py mounts plugin routers WITHOUT a prefix — the manifest's +# route path is documentation only.
