Abstract

The present invention relates to a brand new software-operating method and a software operating system a software operating system comprising a client execution module positioned at the client and a server control and data distribution module positioned at the server; the client execution module further comprising: a process loading sub-module which acquires and loads a software package definition file and establishes an environment required for running an application program on the one hand; and directs the operating system to create a corresponding process for the application program to be executed on the other hand; an I/0 monitoring and processing sub-module which monitors and captures an I/O request of the application program; and a network communication sub-module which communicates with the server through the network according to the request, and downloads the corresponding data to a local computer; the server control and data distribution module further comprising: a control sub-module which coordinates the work between other server sub-modules and the client; and a data distribution sub-module which provides specific data in a software package to the client. For the present invention, because the files or subprograms which are not used are not needed to be loaded, thus greatly reducing the requirements for storage space of the client computer on the one hand, and preventing the procedure of installing the whole software at the client on the other hand.

<

3>

a full path of an executable file is obtained according to a location of the working directory and a file name of the executable file designated by the process loading sub-module, and the process loading sub-module calls an API function of the operating system by taking a path as a parameter to direct the operating system to create a new process;

<

4>

the operating system opens an executable file pointed by the path using the API function while creating the new process, and maps the contents of the executable file to an address space of the process based on a ‘

memory-file mapping mechanism’

;

if the executable file is dependent on other program module files, the operating system repeats the procedure, opens the program module files, and maps the files to the address space; and

the procedure is stopped until all the program module files depended on are opened and mapped to the address space; and

<

5>

the operating system starts to execute an entry function defined in the said executable file, and the entry function continues to call other functions of the file or other files according to the logic of the entry function;

a CPU executes a reading operation on the address of each function while executing each function to obtain the content of a command, decode and execute the command;

a page fault is generated when file data corresponding to the address accessed by the CPU are not in a physical memory, the original execution process is suspended at the moment, a processing subprogram of the page fault initiates an I/O reading request for reading corresponding section of the corresponding file into the physical memory, and then continues the original execution process;

the I/O monitoring and processing sub-module can monitor each I/O reading request, firstly checks whether the data to be read exist in the memory, reads out the data from the memory if yes, and returns the data to an upper caller to complete the reading operation;

if the data do not exist in the memory, the I/O monitoring and processing sub-module requests the network communication sub-module to download the data from the server to the memory, and returns the data to the upper caller to complete the reading operation.

4. A software-operating method of an operating system according to claim 3 further comprising a step of:

<

7>

when the application program is ended, the client execution module monitors the action and executes a corresponding resource cleanup work.

5. A software-operating method of an operating system according to claim 3, further comprising a step of:

<

6>

if the application program attempts to read partial content of a data file, the I/O monitoring and processing sub-module monitors the I/O reading request, checks whether the data to be read exist in the memory, reads out the data from the memory if yes, and returns the data to the upper caller to complete the reading operation;

if the data do not exist in the memory, the I/O monitoring and processing sub-module requests the network communication sub-module to download the data to the memory, and returns the data to the upper caller to complete the reading operation.

6. A software-operating method of an operating system according to claim 5, further comprising a step of:
