From 8ed3ff44d9761afc7c256f6d20d320ae9f3895f0 Mon Sep 17 00:00:00 2001 From: pranaysb Date: Wed, 15 Jul 2026 21:29:18 +0530 Subject: [PATCH 01/23] chore: untrack SQLite database and compiled .pyc artifacts from git These were committed before .gitignore covered them, so git kept tracking them. apiforge.db had grown to 20MB of local job history.

Observed failing 5/5 attempts on a 2-endpoint spec. - Feed diagnostic_feedback + previous script + previous stderr into the schema validator prompt - Lint schema-validation scripts before execution (syntax, pytest ban, MockTransport enforcement in SYNTHETIC mode) via a shared lint_test_script() helper also used by test_linter_node - Guard the diagnoser against misdiagnosis: a SyntaxError raised by the test script itself can never be an SDK bug, so never patch the SDK for it (observed: it patched models.py for a one-line script error) - Declare the endpoint/state fields actually used (schema_validated, validation_mode, execution_stdout/stderr, auth_credentials) Co-Authored-By: Claude Fable 5 --- backend/app/agents/nodes.py | 106 ++++++++++++++++++++++-------------- backend/app/agents/state.py | 9 ++- 2 files changed, 73 insertions(+), 42 deletions(-) diff --git a/backend/app/agents/nodes.py b/backend/app/agents/nodes.py index 50f4b26..58683fa 100644 --- a/backend/app/agents/nodes.py +++ b/backend/app/agents/nodes.py @@ -98,6 +98,36 @@ def get_defined_symbols(code: str): return errors +def lint_test_script(code: str, require_mock_transport: bool = True) -> list[str]: + """Statically validates a generated test script: syntax, banned imports, + and (optionally) that httpx.MockTransport is used so no real network + calls are made.""" + errors = [] + try: + tree = ast.parse(code) + except SyntaxError as e: + return [f"SyntaxError: {str(e)}"] + + for node in ast.walk(tree): + if isinstance(node, ast.Import): + for alias in node.names: + if 'pytest' in alias.name: + errors.append("BANNED_IMPORT: 'pytest' is not allowed.

Two wrong fixes tried and rejected before this one (see main.py comments and tests/test_error_handling.py for the regression coverage): 1. @app.exception_handler(Exception) - routes through Starlette's ServerErrorMiddleware, which sits outside every add_middleware() layer including CORS, regardless of registration order. 2. An @app.middleware("http") handler registered AFTER CORSMiddleware - Starlette's add_middleware() prepends (insert(0, ...)), so the LAST registered middleware ends up OUTERMOST. Registering after CORS put it outside CORS, same bypass. Fix: register the exception-catching middleware BEFORE CORSMiddleware, so CORS ends up outermost and wraps its responses too. Verified against the live uvicorn process (not just TestClient) with a temporary crash route.
