Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is elaborated.
Embodiment one
The present embodiment discloses a kind of hot update method of Lua script, describes as an example of Lua script A example, as shown in Figure 1, may further comprise the steps:
Step S1, startup master routine, embedding in this master routine has Lua script manager and Lua virtual machine, and sets up a global data manager in described Lua virtual machine.Wherein, Lua script manager is for bookkeepings such as the loading of carrying out the Lua script, unloading, upgradings; The Lua virtual machine then is used for link and explains the Lua script; The global data manager then is used for the operating data of system are unified to deposit and manage.
In the present embodiment, master routine, claim again main frame, refer to the program that the various large-scale amusement community systems such as call voice are independently provided, it can call subroutine, and do not called by any subroutine, simultaneously also be the core of the various large-scale amusement community system service routines such as call voice.Among the present invention, comprise Lua script manager and Lua virtual machine in this master routine, dynamic load Lua script is to realize the corresponding specific operation flow of this Lua script flexibly.
Preferably, the described master routine of the present embodiment is write by code efficiency and high C and the C Plus Plus of degree of ripeness, thinks that the Systems balanth operation provides safeguard.
Step S2, Lua script manager load Lua script A, and by the link of Lua virtual machine and explanation Lua script A, and when loading Lua script A, being kept in the global data manager with the data structure initialization of needs and with primary data, and the first module name of in the Lua virtual machine, naming Lua script A.
In the present embodiment, adopt the Lua script to write the changeable corresponding specific service logic flow processs of entertainment systems of demand such as call voice amusement community.Because the Lua script has that volume is little, toggle speed is fast, be fit to be embedded in other program, be easy to by the C/C++ code call and easily understand and the characteristics such as maintenance, thereby provide greatly convenient for expansion, renewal and the maintenance and management of this system.
Step S3, in service, the data structure that Lua script A directly quotes in the global data manager is deposited service data; When breaking down among the Lua script A (being the service logic fault mostly), by Lua script manager the first module name of corresponding Lua script A in the Lua virtual machine being set to sky, and unloading this Lua script A.Service data among the Lua script A of unloading can be kept in the global data manager, has guaranteed the integrality of data.And as usual normal operation of other normal Lua script in this system (for example: Lua script B, Lua script C etc.).
In this step, because when update system, the Lua virtual machine can stop you to reload identical module (being the Lua script), so before again being written into, need the first corresponding in loaded module list module name is set to sky, indicate the Lua virtual machine with this, this Lua script is invalid at present, and the Lua virtual machine just can again link and explain amended script like this.
Step S4, after the traffic failure logic of Lua script A is repaired, Lua script manager reloads the Lua script A after the reparation, and has before put the first module name that again writes Lua script A in the first corresponding module name of the empty Lua script A with after this fault restoration at the Lua virtual machine.Wherein the Lua virtual machine judges that according to the first module name of the Lua script A that again writes this Lua script A has loaded successfully, is in an effective state that can link and explain.
