Detailed Description
The core of the invention is to provide a single-machine program upgrading method and a single-machine program upgrading device in the service operation process, which realize that the program is not closed and the service is not completely interrupted in the program upgrading process and improve the working efficiency.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention provides a single-machine program upgrading method in a service operation process, as shown in fig. 1, fig. 1 is a flowchart of the single-machine program upgrading method in the service operation process provided by the present invention, and includes the following steps:
step S1: storing a program code for updating and informing an upgrading program to start upgrading, wherein the upgrading program checks the current version number of the program to be upgraded and judges whether the program to be upgraded can be upgraded according to the current version number, and the program code for updating comprises a new configuration management code and a new service operation code;
the method comprises the steps that a program code for updating is stored under a file system path of a program to be upgraded, the upgrading program checks the current version number of the program to be upgraded and judges whether the program to be upgraded can be upgraded or not so as to prevent error upgrading and repeated upgrading; the new configuration management code mainly manages the system configuration data with less persistence, and the new service operation code mainly manages the operation data with frequent change in the memory. The part of the program to be upgraded which can be upgraded on line needs to be put into a dynamic library.
Step S2: if the program to be upgraded can be upgraded, the upgrading program firstly closes the user configuration function of the program to be upgraded and loads a new configuration management code into the program to be upgraded;
step S3: executing the data initialization function of the new configuration management code, distributing new configuration management data and enabling the new configuration management data to be compatible with the original configuration management data;
it should be noted that the original configuration management data may be referred to by the old service running code and the new configuration management code, and if there is a new data segment, an index needs to be added to the global data table.
Step S4: loading a new service running code, and switching to the new service running code and running the new service running code under the condition that the service of the new service running code is not accessed and changed currently;
the original service running code needs to be made into a large loop mode, the large loop mode requires that a long-time loop or blocking code cannot exist in the original service running code, and the original service running code needs to be executed quickly, so that the service running can be suspended at any time, and the code replacement is carried out. The condition that the service of the new service operation code is not accessed and changed currently is the time when the service of the program to be upgraded is suspended. The front-end non-upgraded program code needs to maintain connection with the client or the service, and the connection is kept not disconnected within a short switching time.
It should be noted that before switching the new service running code, the new service running code needs to be initialized, so that the new service running code is not initialized when running, and thus can run immediately. In the process of switching to the new service operation code, a code written by any one of programming languages of C, C + +, or JAVA may be used as a tool for switching, and of course, the present invention does not limit the specific programming language of the switching tool.
Step S5: and opening a user configuration function, operating the new configuration management code and updating the current version number.
Preferably, the case that the service of the new service running code is not currently accessed and changed includes:
judging whether the instruction of the current thread can access and change the service of the new service operation code;
and if the instructions of the threads can access and change the service of the new service running code, shielding the instructions of the threads which can access and change the service of the new service running code.
In other preferred embodiments, the case where the service of the new service run code is not currently accessed and changed includes:
and locking the instruction of the thread outside the new service operation code.
It should be noted that locking all instructions of the new service running code outside the new service running code needs to be performed before switching the new service running code.
It can be understood that by shielding or locking the instructions of the thread, the new service code is not run before switching, so that the problems that the new and old service running codes run simultaneously to cause the thread instructions to be unable to execute or the instructions to be invalid when the codes are switched are prevented, which may cause the failure of switching the codes, and therefore, the occurrence of the problems can be avoided, so that the switching of the codes can be correctly and effectively performed.
Preferably, the upgradeable code of the program to be upgraded contains a reserved field, and the default value of the reserved field is 0, and the method further comprises:
if the new service operation code detects that the reserved field is the default value, initializing a new data space, and simultaneously changing the default value.
It should be noted that the upgradeable code of the program to be upgraded needs to have a reserved field, and the program code for updating needs to have a reserved field for future use in upgrading.
The invention provides a method for upgrading a single machine program without interrupting service operation, which comprises the steps that an upgrading program checks the current version number of a program to be upgraded and judges whether the program to be upgraded can be upgraded or not; if the program to be upgraded can be upgraded, the upgrading program firstly closes the user configuration function of the program to be upgraded and loads a new configuration management code into the program to be upgraded; executing the data initialization function of the new configuration management code, distributing new configuration management data and enabling the new configuration management data to be compatible with the original configuration management data; loading a new service operation code, and switching to the new service operation code and operating the new service operation code under the condition that the service of the new service operation code is not accessed and changed currently; and opening a user configuration function, operating the new configuration management code and updating the current version number.
Compared with the prior art that the service needs to be interrupted and closed when the program is upgraded, and the program is restarted and the service is restarted after the upgrade is finished, the method and the system for upgrading the program do not need to be closed when the program to be upgraded is upgraded, only need to temporarily stop the currently running service of the program to be upgraded when a new service running code is switched, and can follow the service before running instead of restarting the service after the program to be upgraded is upgraded, so that the method and the system for upgrading the program realize that the program is not closed and the service is not completely interrupted in the process of upgrading the program, and improve the working efficiency.
