From 9302695439b20bd391b5e6a32bccec4812939a11 Mon Sep 17 00:00:00 2001 From: Hiroshi Nishio Date: Sun, 19 Apr 2026 22:41:02 -0700 Subject: [PATCH] Retry transient upstream errors in handle_exceptions decorator Sentry AGENT-36Z/36J were transient GitHub 5xx on git push surfacing as a plain ValueError from run_subprocess wrapping the remote stderr. The existing retry path in the decorator only fired on requests.HTTPError rate limits, so these ValueErrors bubbled straight through, reported to Sentry, and the push just failed. Adds is_transient_error to recognize GitHub 5xx, remote Internal Server Error from subprocess, and HTTP 5xx message markers. handle_exceptions now retries the wrapped function up to TRANSIENT_MAX_ATTEMPTS (3) with linear backoff when the raised exception matches. 5xx responses almost always mean the server did not complete the operation so retry is safe by default for all decorated functions; non-transient exceptions still fail fast on the first attempt. Split handle_http_error, handle_json_error, and handle_generic_error into their own files and extracted GitHub 403/429 rate-limit handling into handle_github_rate_limit. handle_exceptions.py is now just the decorator plus the retry loop. Exempted handle_exceptions.py from the cast-usage lint: the generic decorator with ParamSpec + TypeVar genuinely needs cast to bridge the async wrapper's Coroutine[..., R] against the declared Callable[P, R]. Added regression tests for git_commit_and_push retry behavior, the new helpers, and is_transient_error classification. Updated CLAUDE.md to flag hard-wrapped comment sentences. Repointed existing tests that patched utils.error.handle_exceptions.sentry_sdk to patch the module function directly, which works across all new helper locations. Also rewrote pre-existing partial in/not-in assertions in touched test files to exact == equality per CLAUDE.md. --- CLAUDE.md | 2 +- pyproject.toml | 2 +- scripts/lint/check_cast_usage.sh | 4 +- services/aws/test_delete_scheduler.py | 8 +- services/git/git_commit_and_push.py | 2 + services/git/test_git_commit_and_push.py | 126 ++++++- .../test_get_remote_file_content_by_url.py | 50 ++- utils/error/handle_exceptions.py | 340 ++++++++---------- utils/error/handle_generic_error.py | 37 ++ utils/error/handle_github_rate_limit.py | 65 ++++ utils/error/handle_http_error.py | 81 +++++ utils/error/handle_json_error.py | 26 ++ utils/error/is_transient_error.py | 31 ++ utils/error/test_handle_exceptions.py | 108 ++++-- utils/error/test_handle_generic_error.py | 61 ++++ utils/error/test_handle_github_rate_limit.py | 111 ++++++ utils/error/test_handle_http_error.py | 116 ++++++ utils/error/test_handle_json_error.py | 48 +++ utils/error/test_is_transient_error.py | 73 ++++ uv.lock | 2 +- 20 files changed, 1034 insertions(+), 259 deletions(-) create mode 100644 utils/error/handle_generic_error.py create mode 100644 utils/error/handle_github_rate_limit.py create mode 100644 utils/error/handle_http_error.py create mode 100644 utils/error/handle_json_error.py create mode 100644 utils/error/is_transient_error.py create mode 100644 utils/error/test_handle_generic_error.py create mode 100644 utils/error/test_handle_github_rate_limit.py create mode 100644 utils/error/test_handle_http_error.py create mode 100644 utils/error/test_handle_json_error.py create mode 100644 utils/error/test_is_transient_error.py diff --git a/CLAUDE.md b/CLAUDE.md index 312cb150f..978156fac 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -71,7 +71,7 @@ python3 scripts/aws/filter_log_events_across_streams.py --hours 12 --owner Foxqu ## Coding Standards - **No DOCSTRINGS**: Don't add unless told.
