Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as limiting to the invention.
The technical problem to be solved in the present invention is in Linux software development process, it is impossible to operationally waits and accesses application
The internal data structure and change application program of program are set.For example in debugging, how the Debug of Real-Time Switch process is printed
How information, obtain the internal information of process, and in the application, how in real time according to environment configurations application process etc..
As shown in figure 1, process configuration management system includes application apparatus, kernel device and file storage device, using dress
Put and kernel device is connected by a communication interface, file storage device connects application apparatus and kernel device respectively, the communication
Interface is netlink interfaces；Application apparatus includes first storage component and the first control unit, and first storage component includes
Multiple the first independent memory spaces（One of them is only shown in figure）, storage has application program in each memory space
Information；First control unit sends operation requests according to the request of application program to kernel device；Have in file storage device
Proc file system, proc file system includes proc files and proc files.
Kernel device includes second storage component and the second control unit, and second storage component connects the second control unit
Part；Second control unit threaded file storage device, and the first control unit is connected by communication interface；Second storage component bag
Include multiple the second independent memory spaces（One of them is only shown in figure）, each second memory space, which is deposited, has one uniquely
The control unit of process sequence confession second distributes to application program；Also include multiple the 3rd independent storages in second storage component
Space（One of them is only shown in figure）, each 3rd memory space, which is used to depositing a correspondence proc file or folder, to be deposited
Path is stored up, the store path is the relative path of this document or file relative to proc file system root directories（I.e. relative to/
Proc path；For example ,/proc/appproc/test relative path is appproc/test）, for the second control unit
Called when being written and read monitoring.
It is the schematic flow sheet of process configuration management implementation method as shown in Figure 2-5, wherein Fig. 2 illustrates for overall procedure
Figure, its specific steps include：
Before being managed for configuration, application program needs to register to kernel device first：Application program is to the first control unit
Part sends registration request, and the first control unit sends the registration request, the second control by communication interface to the second control unit
Part transfers a process sequence number from the second memory space of second storage component and distributes to the application program, completes note
Volume process；
The second control unit first checks for this before receiving the addition of application program transmission or deleting file request afterwards
Whether application program is assigned process sequence number：If allocated, into next step；If being not yet allocated, the
Two control units return to the announcement information of processing failure by communication interface to the first control unit, and the first control unit should to this
The announcement information is returned to program, reminder application first completes registration process；I.e. kernel device only handles registered application
Program, is disregarded to unregistered application program.
After application program has been allocated with process sequence number, the application program can carry out following additions and delete text
The process of part or file：
As shown in figure 3, add file or file：First control unit reads add file or the text that application program is sent
The request of part folder and the relative path of file or folder added is needed, the first control unit is by the operation requests and phase
Path is sent to the second control unit by communication interface；Second control unit is according to the relative path in proc file system
Middle addition new file or file；The relative path is stored in the 3rd memory space by the second control unit.
As shown in figure 4, deleting file or folder：First control unit reads the deletion file or text that application program is sent
The relative path for the file or folder that the request of part folder and needs are deleted, the first control unit is by the request and with respect to road
Footpath is sent to the second control unit by communication interface；Second control unit is according to the relative path, in proc file system
Find corresponding file or folder and delete；The second control unit deletes the corresponding phase being stored in the 3rd memory space simultaneously
To path.
After add file or file, the operation that user can be write or be read to it, the operation it is final by
Application program is completed, but application program is in itself and can not to differentiate an operation be write-in or reading, and it is in the process of running
Also can not voluntarily it be write or read operation, it is therefore desirable to add kernel device to be written and read the monitoring of operation：
As shown in figure 5, when user is written and read operation to a proc file or folder, in kernel device
Two control units, and generation one includes the notification message of monitoring content；Second control unit passes through above-mentioned notification message logical
Letter interface is sent to the first control unit, and the first control unit sends the notification message to application program, application program according to
The notification message, the operation for calling default call back function to be read or write.
The content of above-mentioned notification message includes：
Message id：System generates an ID for a notification message automatically；
Message-length（LEN）；
File type（TYPE）：0 represents file, and 1 represents file；
Relative path（PATH）；
Additional data（DATA）；
Return value in detail after processing（RET）；
Specific message format is as shown in the table：
| ID | LEN | TYPE | PATH | DATA | RET |
The structure of call back function is called to be defined as follows in application program：
typedef struct APPPROC_FILE_STRUCT
Wherein：
path：Relative to the absolute path of/proc catalogues
fileType ：File type, 0 represents file, and 1 represents file
proc_read :Call back function is read, when user reads file, the function can be called
proc_write :Call back function is write, when user is to file write data, the function can be called
data：Parameter, is not explicitly defined, incoming when proc_read and proc_write is called.
next:Point to next proc file structures.
The read-write event of one proc file can be monitored by multiple application programs, and each application program can be taken not
Same processing.When there are such a proc files, multiple application programs can be configured simultaneously when creating this document.Read one
It is individual monitored by many application processes file when, the global configuration information of these processes can be obtained, each process can be exported
The information of oneself.Above-mentioned mechanism effectively easily can configure multiple application processes simultaneously.
The present invention can access the setting of interior data structure and change application program, optimization when application program is run
The interaction sense of application program and user in Linux system.
Preferred embodiments of the present invention are the foregoing is only, embodiments of the present invention and protection model is not thereby limited
Enclose, to those skilled in the art, should can appreciate that made by all utilization description of the invention and diagramatic content
Scheme obtained by equivalent substitution and obvious change, should be included in protection scope of the present invention.
