…ion() Since MIN_SUPPORTED_WIRE_VERSION=8 (MongoDB 4.2+), use_command() always returns True and OP_MSG is always used. Remove the unreachable OP_QUERY branches from Server.run_operation(), along with the dead else-branches in Cursor and CommandCursor that referenced _OpReply. - Hard-code use_cmd=True / apply_timeout=True in run_operation() - Always use user_fields=_CURSOR_DOC_FIELDS and legacy_response=False - Remove isinstance(reply, _OpMsg) exhaust check (reply is always _OpMsg) - Hard-code from_command=True in Response/PinnedResponse construction - Remove dead else-branches with assert isinstance(response.data, _OpReply) in Cursor._send_message and CommandCursor._send_message - Add scope document PYTHON-5676-scope.md outlining all four phases
Eliminate the ~13-line _COMMAND_LOGGER/_debug_log boilerplate that was copy-pasted identically across five command execution paths. Add three helpers to pymongo/command_helpers.py and call them from all five sites. - New pymongo/command_helpers.py: _log_command_started, _log_command_succeeded, _log_command_failed — pure functions, no I/O, no async/sync split needed - network.py, server.py, bulk.py, client_bulk.py: replace inline _debug_log blocks with helper calls; remove _COMMAND_LOGGER/_CommandStatusMessage imports where no longer needed
Extract _network_command_core() from network.command() to handle the common send/receive/APM/decrypt pipeline. Both the standard command path and the cursor (find/getMore) path now use the same core function. - New _network_command_core() in network.py: takes a pre-built message and handles APM, send_message, receive_message, unpack, process, check, decrypt — returns (docs, reply, duration) - command() is now a thin wrapper: encode → _network_command_core → return docs[0] - run_operation() is now a thin wrapper: build message → _network_command_core → wrap in Response/PinnedResponse - _CURSOR_DOC_FIELDS moved from server.py to network.py (only used in core) - server.py drops _decode_all_selective, _check_command_response, _convert_exception, NotPrimaryError, OperationFailure imports
