研究方向

The traceback runs through b2sdk/bucket.py (_upload_small_file), raw_api.py (upload_file) and b2http.py (_translate_and_retry and _translate_errors), where the BrokenPipe and 503 ServiceError are raised. Start by reading the retry logic in b2http.py and reproducing a failed upload to see whether BrokenPipe is retried. Done would mean the transient upload error is retried or handled cleanly, with a test covering it. The issue is 2500+ days old with six comments and no decision, so confirm current behaviour with maintainers first.
