From 37ece145fac5d366d4e73cb06aba0c7235084c8a Mon Sep 17 00:00:00 2001 From: Ed_ Date: Sat, 20 Jun 2026 15:48:00 -0400 Subject: [PATCH] refactor(ai_client): apply Re-Raise Pattern 1 to 4 RETHROW sites (Phase 12) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per styleguide §7.6 Pattern 1: 'catch + convert + raise as different type' requires 'raise X from e' to preserve the original exception in the traceback. Sites updated: Site 1 (L277 _load_credentials): except FileNotFoundError as e: raise FileNotFoundError(f'...') from e Sites 2+3 (L878+L879 _default_send, nested in run_with_tool_loop): if not res.ok: raise res.errors[0].original from None raise RuntimeError(...) from None The exceptions come from a Result, not a local except; 'from None' suppresses the implicit context. Site 5 (L2061 _send inside _send_gemini_cli): raise cast(Exception, send_result.errors[0].original) from None Site 6 (L2742 _dashscope_call): raise classify_dashscope_error(_dashscope_exception_from_response(resp)) from None KNOWN LIMITATION: the audit script does not have a heuristic for 'raise X from e' / 'from None' (Pattern 1). The sites remain INTERNAL_RETHROW in the audit. INTERNAL_RETHROW is 'suspicious but not violation' (strict mode accepts). Adding a heuristic requires Tier 1 approval per the conventions. Audit: ai_client RETHROW 6 -> 5 (site 4 migrated separately; these 4 sites stay as INTERNAL_RETHROW by audit classification but follow Pattern 1 by styleguide). --- src/ai_client.py | 37 +++++++++++----- tests/tier2/phase12_pattern1_test.py | 64 ++++++++++++++++++++++++++++ 2 files changed, 91 insertions(+), 10 deletions(-) create mode 100644 tests/tier2/phase12_pattern1_test.py diff --git a/src/ai_client.py b/src/ai_client.py index 84705eb8..0db21274 100644 --- a/src/ai_client.py +++ b/src/ai_client.py @@ -269,11 +269,10 @@ def get_credentials_path() -> Path: def _load_credentials() -> dict[str, Any]: cred_path = get_credentials_path() - #TODO(Ed): Exception(Review) try: with open(cred_path, "rb") as f: return tomllib.load(f) - except FileNotFoundError: + except FileNotFoundError as e: raise FileNotFoundError( f"Credentials file not found: {cred_path}\n" f"Create a credentials.toml with:\n" @@ -282,7 +281,7 @@ def _load_credentials() -> dict[str, Any]: f" [deepseek]\n api_key = \"your-key\"\n" f" [minimax]\n api_key = \"your-key\"\n" f"Or set SLOP_CREDENTIALS env var to a custom path." - ) + ) from e def _try_warm_sdk_result(name: str) -> Result[Any]: """Try to get a warmed SDK module.
