摘要： Embodiments of the present invention disclose a resource leak detection method, apparatus, and system. The method includes: obtaining a target resource called when target code of a program runs, where the target code is partial code in program code; determining a first storage resource amount occupied by the target resource; determining whether the first storage resource amount occupied by the target resource satisfies a first preset condition; and if the first storage resource amount occupied by the target resource satisfies the first preset condition, determining a storage location of the target code as a resource leak location. In the embodiments of the present invention, the target code of the program can be tracked, and further, by means of detection, the storage location of the target code can be determined as the resource leak location. It is unnecessary to track all resource allocation and release, thereby reducing performance overheads and improving resource leak detection efficiency.

摘要： Embodiments of the present invention provide a method and a device for processing a failure in at least one distributed cluster, and a system. The at least one distributed cluster includes a first distributed cluster. The first distributed cluster includes a first Master node, a first Slave node, a first reference node, and a first secondary node that serves as a backup of the first Master node. The first secondary node receives a heartbeat message that is sent by the first reference node and that includes first indication information that is used to indicate that the first reference node is disconnected from the first Master node. The first secondary node determines, according to the first indication information, that the first reference node is disconnected from the first Master node. When it is detected that a heartbeat message sent by the first Master node to the first secondary node is interrupted, the first secondary node determines that the first secondary node is also disconnected from the first Master node. The first secondary node determines that the first Master node is faulty. In the embodiments of the present invention, a failure detection time can be effectively shortened.

摘要： A service registration method and usage method, and a related apparatus are used to reduce risks generated when a service of an AP-type service providing node cannot be registered and a CP-type service providing node provides a service since distributed characteristics of a service providing node are not distinguished in a network partition scenario. The method is: obtaining, by a registration service node, network partition information, and receiving a registration request of a service providing node, where the registration request carries a distributed characteristic of the service providing node, and the distributed characteristic meets both consistency and partition tolerance, or meets both availability and partition tolerance; and determining, by the registration service node according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed.
