@tianfeng-yang I would suggest to use ShutdownSubscriptions from https://github.com/project-chip/connectedhomeip/blob/master/src/app/InteractionModelEngine.cpp#L296, and remove abort API. and leave the below unchanged. |

Changing the API like this is a bit extensive, and I can't confirm whether it will cause a chain reaction. |

Fixed #32310
ReadClientlife cycle isOnDone. IfOnErrorhappend,OnDonewill eventually be executed. In the existing Python code,delete itis executed inOnDone. At this time,pCallbackandpReadClient(moved frompychip_ReadClient_Read) have both been deleted. , After that, if the python application executesSubscriptionTransaction.Shutdown()ordelete,pychip_ReadClient_Abortwill be executed, which will causepCallbackto be deleted again, causing the application to crash. Therefore, when callingShuddown()ordeleteon the python side, you need to determine whetherOnErrorhappend. IfOnErrorhappend, you do not need to callpychip_ReadClient_Abortagain. If not, it is a normal delete behavior on the application side.ReadClientalso describes that after deletingReadClient,OnDonewill not be executed, so we can directly deleteReadClientin the callback ofOnDone(the life cycle ofReadClienthas ended), so that there is no need to move the memory ofpReadClienttoReadClientCallbackinpychip_ReadClient_Read.@notes: There is no problem moving
ReadClienttopCallbackhere, butWriteClientCallbackis also not moved, just for consistency reasons.Follow the advice
The following two points are split into PR #32308
