Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, be in an embodiment of the present invention a kind of based on run time context the standing posture service that goes out realize the system architecture diagram of system.It is somebody's turn to do realize, based on the standing posture service that of context when running, at least one calculating node 20 that system 100 includes controlling end 10 and communicating to connect with control end.
Seeing also Fig. 2, Fig. 3, Fig. 2 is the structured flowchart calculating node, and Fig. 3 is the structured flowchart controlling end.Described calculating node 20 includes main connection initiation module 21, functional module load-on module 22, computing module 23.
Described control end 10 includes authentication module 11, main link block 12, enquiry module 13, judge module 14, more new module 15, conversation module 16.
Described main connection initiation module 21 is for controlling end 10 initiation connection.
Described authentication module 11 is for carrying out authentication to the calculating node 20 initiating to connect.
Described main link block 12 is after passing through calculating node 20 authentication when authentication module 11, maintain described connection as main connection, and create process context, process context comprises service function table, service function table registers with the service function that functional module is corresponding.
Wherein, on the basis of RFI calling model, set of service classification is incorporated in different functional modules by the present invention, and each module has version number, classification information.At the porch registration service function of module in service function table, service function table saves the ID of each service function and corresponding service function, and it is defined as follows:
Map<FunctionKey,FunctionAgent>
Described service function table is arranged in process context, so whole process can access.
Described enquiry module 13 for calculating classification and the version number of node 20 existing capability module by main Connection inquiring.
Whether described judge module 14 has, for judging according to described classification and version number to calculate in node 20 existing capability module, the functional module not updated, and when judging the functional module not updated, notice calculates node 20 and loads functional module.
Described more new module 15, for when judge module is determined with the functional module not updated, is updated by the main connection corresponding service function of the functional module to not updating, and then notice calculates node 20 and loads functional module.
Specifically, new service function will replace old service broker's function, and session afterwards will use new service function automatically, it is not necessary to restarts calculating node serve routine.Updating service process itself is also a conversational services, causes access conflict in order to avoid updating service and other conversation request, and updating service process must be completed by main connection.
Described functional module load-on module 22 is used for loading functional module.
Described conversation module 16 is connected for being conversated with calculating node 20 by main connection.
Described computing module 23 is for carrying out data calculating according to the instruction of session connection and result being returned.
Refer to Fig. 4, be the functional block diagram of computing module.Described computing module 23 specifically includes thread creation submodule 231, binding submodule 232, thread exit submodule 233.
Thread creation submodule 231, after receiving, when calculating node 20, the conversational services that control end 10 is initiated, is set up session connection with controlling end, and is created corresponding thread context only with session connection.
Binding submodule 232 for when calculate node 20 receive control that end sends open file instruction after, file handle is bound with thread context, and returns file handle ID to control end 10；
Thread exit submodule 233 for when calculate node 20 detect conversation end condition meet time, exit thread and close file handle.Wherein, the condition of described conversation end includes that fair termination, Network Abnormal exit, service abnormal exiting.
It is automatically switched off handle to be realized by context object or destructed behavior, in windows, handle belongs to kernel objects, can close different types of handle by unified API, and the function policy being therefore automatically switched off handle simplifies the management of handle resources to a certain extent.Operation context, by calling the acquisition context approach of subclass, accesses subclass context object.
No matter session terminates in what manner, and file all can be released.Being presented herein below and opening file is the false code that file handle is tied to thread context.
Wherein ThreadRuntimeContext is thread context, is registered in context carrier by file handle by static function, and therefore file handle can be automatically releasable when thread exits.For other non-handle resources, it is also possible to exit operation by queue_exit_handler is self-defined, the final block being similar in abnormality processing.
Refer to Fig. 5, be the schematic diagram of context class definition.The base class of context when GenericRuntimeContext is to run in figure, encapsulates following operation:
Base class obtains the context carrier of subclass by get_context, and the context carrier of process context subclass is the whole service phase of application program life cycle, and access domain is process territory；The life cycle of the context carrier of thread context subclass is the runtime of each thread, and access domain is thread territory, and the variable that such as thread context is arranged can not be by other thread accesses.
Refer to Fig. 6, be the class definition figure of context carrier.Wherein values be set_value and get_value access argument table, handlers be queue_exit_handler operation function object, handles be context destructed be the handle being automatically switched off, section be limit access competition semaphore.
When context is destructed, all variablees in argument table can be released, and the destructor function of object can be called；Destructed operation can be called successively, and handle can be closed successively.For thread context, semaphore is void type, and semaphore does not exist lock and the operation unlocked, because it is unlikely that access competition in same thread.
During operation, the part of object most critical is when context carrier creates and discharge.In realization, process context creates context carrier when performing context operations for the first time, and thread context then creates context carrier when each thread performs context operations for the first time, and this does not affect use logic.
Process context is different from single example, and single example is usually the single example run in module, is language level.When a process is made up of multiple modules, each module can have respective single example for same type, and in RFI model, service function needs to be registered in the agent list in process territory, and the single example model in module can not meet requirement.In Windows, there is not the process list example of language level, use the environmental variable in document " Modern C++Design Generic Programming and Design Patterns Applied; Andrei Alexandrescu " and single example model realization process context of Feng Huang Model herein, address by environmental variable access context carrier list example, when accessing for the first time, owing to environmental variable does not exists, need to create single example and register the address of single example in environmental variable.
Above-mentioned Conversation Model based on thread context, eliminate object interface contract, but require that each conversational services is corresponding to calculating a thread of node, i.e. when controlling end and initiating a conversational services, require that calculating node creates a new thread and a new connection, this thread and connection process all service requests in conversation procedure, meanwhile, file that service node uses in this thread or other resources, will be tied in thread context by service function.When session connection terminates in any form, thread will automatically exit from, and in conversation procedure, when the exception that service function produces makes thread exit, the vital stage the most simultaneously terminating session connection, thread and session connection is consistent.
Refer to Fig. 7, it is a kind of based on the execution flow chart standing posture service implementing method of context when running in an embodiment of the present invention, the method realizes in system 100 based on the standing posture service that of context when running described in running on, and the method comprises the steps:
Step S101, calculating node initiate to connect to controlling end；
Step S102, control after end carries out authentication to the calculating node initiating to connect, to maintain described connection as main connection, and create process context, process context comprises service function table, service function table registers with the service function that functional module is corresponding；
Wherein, on the basis of RFI calling model, set of service classification is incorporated in different functional modules by the present invention, and each module has version number, classification information.At the porch registration service function of module in service function table, service function table saves the ID of each service function and corresponding service function, and it is defined as follows:
Map<FunctionKey,FunctionAgent>
Described service function table is arranged in process context, so whole process can access.
Step S103, control end calculate classification and the version number of node existing capability module by main Connection inquiring, and judge to calculate in node existing capability module whether have the functional module not updated according to described classification and version number, if so, enter step S104, if it is not, enter step S105；
Step S104, control end and be updated, subsequently into step S105 by the main connection corresponding service function of functional module to not updating；
Step S105, calculating node load functional module, subsequently into step S106；
Specifically, new service function will replace old service broker's function, and session afterwards will use new service function automatically, it is not necessary to restarts calculating node serve routine.Updating service process itself is also a conversational services, causes access conflict in order to avoid updating service and other conversation request, and updating service process must be completed by main connection.
Step S106, control end and conversate by main connection is connected with calculating node, and carry out data calculating and result passback by session connection indicating gage operator node.
