Shield process, similarly, when finger daemon reads the first system file, then show that host process has terminated, so, execution is aroused
Operation of host process, etc..
It is described in detail individually below.It should be noted that the sequence number of following examples is not as preferably suitable to embodiment
The restriction of sequence.
Embodiment one,
The angle of the supervising device of application process will be described for the embodiment of the present invention, the supervising device of the application process
It can specifically integrate in the terminal, the terminal can include the equipment such as mobile phone, tablet personal computer, notebook computer or PC.
A kind of monitoring method of application process, including：Call the host process and finger daemon of application to be monitored；Pass through the master
Process creation the first system file and second system file；Reading power to the first system file and second system file respectively
Limit is configured so that the first system file can just be read after host process termination by finger daemon, and cause this
Two system file can just be read after finger daemon termination by host process；Second system file is read by the host process, with
And the first system file is read by the finger daemon；When host process reads second system file, arouse the finger daemon；
When finger daemon reads the first system file, arouse the host process.
As shown in Figure 1 b, the flow of the monitoring method of the application process specifically can be as follows：
101st, the host process and finger daemon (Daemon) of application to be monitored are called.
Wherein, the host process of application to be monitored refers to the parent process in application to be monitored, and finger daemon is a kind of fortune
Row backstage special processing, it can independently of control terminal, and periodically perform certain task or wait it is pending certain
The event occurred a bit, in embodiments of the present invention, finger daemon can mutual process monitorings with host process.
102nd, the first system file and second system file are created by the host process.
Wherein, the content and form of the first system file and second system file can according to the demand of practical application and
It is fixed.
In addition, in order to avoid host process and finger daemon are in the different stages, the state that can not be completed between two processes is same
Step, it can first clear up and last arouse the finger daemon remained during process, i.e. create the first system file passing through the host process
Before second system file, the monitoring method of application process can also include：
Clear up finger daemon.
For example the finger daemon of the calling can be specifically terminated, and finger daemon, etc. is aroused by host process again.
103rd, the reading authority of the first system file and second system file is configured respectively so that first system
File unite after host process termination, can just be read by finger daemon, and causes the second system file in finger daemon
After only, it can just be read by host process.
For example, it can be configured by reading authority of the host process to the first system file so that the first system file exists
It after host process stops, can just be read by finger daemon, and be carried out by reading authority of the finger daemon to second system file
Setting so that the second system file can just be read after finger daemon termination by host process, such as, specifically can be as follows：
Exclusive lock is established to the first system file by host process；And by finger daemon to second system text
Part establishes exclusive lock.
Because host process has added exclusive lock to the first system file, so, if finger daemon is attempted to obtain the first system text
When the read right of part, it can not be read because current file is locked, the process of lock file can only be waited (i.e. main
Process) abandon exclusive lock to file.Similarly, because finger daemon has added exclusive lock to second system file, so, if master enters
When journey attempts to obtain the read right of second system file, as current file is locked and can not read, can only
The process of lock file is waited, i.e. finger daemon is abandoned just may be used to the exclusive lock of file.That is, do not untied actively in program
Before exclusive lock, only when side's process terminates, system will discharge its all locking resource automatically.Therefore as a side
After process gets the read right of file destination, that is, think that the opposing party's process has terminated, subsequently will be described in more detail, refer to step
Rapid 104 to 106, it is as follows：
104th, second system file is read by the host process, and the first system file is read by the finger daemon.
Wherein, the mode of reading can be configured according to the demand of practical application.For example " obstruction is read " can be used
Mode be read out, i.e., step " reads second system file by the host process, and reads the by the finger daemon
One system file " specifically can be as follows：
Blocked by the host process and read second system file, and blocked by the finger daemon and read the first system text
Part.
Wherein, obstruction reading is referred to when current process needs to read file destination, if the file destination is by it
He reads task occupancy, then will read task suspension in the current process accordingly, until after other reading task uses,
The reading task is just waken up, to be read out to the file destination.
In addition, it should be noted that, " reading " here refers to attempting to obtain read right, i.e. host process is attempted to obtain second
The read right of system file, and finger daemon are attempted to obtain the read right of the first system file.
Optionally, in order to avoid two processes are during synchronization, judge other side's state of a process by accident, do not set up in other side
Judge other side's process when finishing by accident to terminate, and enter arouse and (draw and live) stage in advance, host process can be passed through during synchronization
The 3rd system file is created, and the 4th system file is created by finger daemon, and in the first system for reading other side's process
Before file or second system file, attempt to delete the 3rd system file of other side's process or the 4th system file (row
Except the possibility of erroneous judgement other side's process status), when deleting successfully, just it is read out.That is, " read in step by the host process
Second system file is taken, and the first system file is read by the finger daemon " before, the monitoring method of the application process is also
It can include：
(1) the 3rd system file is created by host process, and the 4th system file is created by finger daemon.
(2) the 4th system file is deleted by the host process, if deleting successfully, execution uses the host process
The step of reading second system file；If deleting failure, after preset time, return and perform by the host process to the 4th
The step of system file is deleted.
(3) the 3rd system file is deleted by the finger daemon, if deleting successfully, execution is guarded by this
Process reads the step of the first system file；If deleting failure, after preset time, return to execution and pass through the finger daemon pair
The step of 3rd system file is deleted.
Wherein, the preset time can be depending on the demand of practical application, preset time and step in step (2)
(3) preset time can be identical or different.In addition, it should be noted that, the execution of step (2) and (3)
Can be in no particular order.
105th, when host process reads second system file, the finger daemon is aroused.
Wherein, the mode of arousing can have a variety of, such as, can use quarter-bell (AlarManager), service (Service),
Broadcast the mode such as (Broadcast) or movable (Activity).
Optionally, arouse efficiency to improve, except can use it is above-mentioned any one arouse mode in addition to, can also adopt
The mode aroused with mixing, i.e., be combined to above-mentioned a variety of modes of arousing, specifically can be as follows：
The finger daemon is aroused using default a variety of arousal patterns successively.
Wherein, arousal pattern, arouse number and the execution sequence of this variety of arousal pattern can be according to practical application
Demand is configured.Such as a variety of arousal patterns can include AlarManager, Service, Broadcast and
Any combination of mode such as Activity, etc..
It should be noted that all kinds of modes of arousing need to be beforehand with initialization, necessary object resource is generated, to ensure to send out
Existing process terminate after can quick response, will not be repeated here.
Optionally, in order to ensure the validity aroused, after arousing to the finger daemon, one can also waited
After the section time, the survival condition of the finger daemon to being invoked detects, to ensure that it can successfully arouse, i.e., in step
After " arousing to the finger daemon ", the monitoring method of the application process can also include：
In the range of setting time, regularly the survival condition of the finger daemon to being invoked detects, if testing result
Indicate that the finger daemon being invoked is not survived, then return and perform the step of arousing to the finger daemon, for example return and hold
The step of row is aroused using default a variety of arousal patterns to the finger daemon successively.
Otherwise, if testing result indicates that the finger daemon being invoked has been survived, flow can terminate.
106th, when finger daemon reads the first system file, the host process is aroused.
Wherein, the mode of arousing can have a variety of, such as, can use AlarManager, Service, Broadcast or
The modes such as Activity.
With step 105 similarly, arouse efficiency to improve, except can use AlarManager, Service,
Broadcast or Activity etc. any one arouses outside mode, can also be that is, more to this by the way of mixing is aroused
The kind mode of arousing is combined, specifically can be as follows
The host process is aroused using default a variety of arousal patterns successively.
Wherein, arousal pattern, arouse number and the execution sequence of this variety of arousal pattern can be according to practical application
Demand is configured.
It should be noted that all kinds of modes of arousing need to be beforehand with initialization, necessary object resource is generated, to ensure to send out
Existing process terminate after can quick response, will not be repeated here.
It should be noted that step 105 and 106 execution can be in no particular order.
Optionally, in order to ensure the validity aroused, after arousing to the host process, one section can also waited
After time, the survival condition of the host process to being invoked detects, to ensure that it can successfully arouse, i.e., in step " to this
Host process is aroused " after, the monitoring method of the application process can also include：
The survival condition of host process of the timing to being invoked detects, if testing result indicates the host process being invoked
Do not survive, then return and perform the step of arousing to the host process, for example return to perform and a variety of arouse mould using default successively
The step of formula is aroused to the host process.
Conversely, if testing result indicates that the host process being invoked has been survived, flow can terminate.
It should be noted that in order to avoid arousing process without limit, cause resource consumption excessive, operation can be aroused to this
Regular hour scope is set, i.e. step " regularly the survival condition of the host process to being invoked detects " is specifically as follows：
In the range of setting time, regularly the survival condition of the host process to being invoked detects.
Wherein, the time range of the setting can be configured according to the demand of practical application, will not be repeated here.
From the foregoing, it will be observed that the present embodiment can call the host process and finger daemon of application to be monitored, created by the host process
The first system file and second system file are built, and respectively to the reading authority of the first system file and second system file
It is configured so that the first system file can just be read after host process termination by finger daemon, and cause second system
File can just be read after finger daemon termination by host process, then, second system file be read using host process, and
The first system file is read using finger daemon, when host process reads second system file, arouses the finger daemon, when
When finger daemon reads the first system file, arouse the host process；It can be seen that the program can by this medium of file,
So that two processes carry out deadlock request each other, so as to realize real-time monitoring and arouse that process terminates, due to this process it
Between deadlock request relative to high-frequency send intention request for, it is not necessary to extra flow is consumed, moreover, reaction speed
Faster, and to system do not require particularly, therefore, the program in terms of existing technologies, can greatly save power consumption,
And improve its applicability.
Embodiment two,
, below will be with linux system according to the method described by embodiment one, and the supervising device of the application process is specific
It is further illustrated exemplified by integrating in the terminal.
In addition, will be specially Linux files a with the first system file in embodiments of the present invention for convenience1,
Second system file is specially Linux files b1, the 3rd system file is specially Linux files a2, the 4th system file is specific
For Linux files b2Exemplified by illustrate.
As shown in Figure 2 a, a kind of monitoring method of application process, idiographic flow can be as follows：
201st, terminal calls the host process and finger daemon of application to be monitored.
202nd, terminal initializes to host process and finger daemon respectively, such as, it can be created by the host process
Linux files a1With Linux files b1, etc., then perform step 203.
Wherein, Linux files a1With Linux files b1Content and form can be depending on the demand of practical application.
Optionally, in order to avoid host process and finger daemon are in the different stages, the state between two processes can not be completed
It is synchronous, before the first system file and second system file is created, it can first clear up and last arouse keeping of being remained during process
Shield process, the finger daemon of the calling can be specifically terminated, and finger daemon, etc. is aroused by host process again.
In addition, create Linux files a in host process1With Linux files b1Before, host process can also carry out Native
(a kind of locally applied) code.
203rd, terminal is synchronized, with right by way of establishment file lock to the host process after initialization and finger daemon
The host process and finger daemon carry out deadlock monitoring.
From host process and the angle of finger daemon, its synchronous flow will be illustrated respectively, for example, specifically respectively below
Can be as follows：
(1) host process.
Referring to Fig. 2 b, the synchronous flow of host process can be as follows：
A2031, host process are to Linux files a1Establish exclusive lock.
So, when finger daemon is attempted to obtain Linux files a1Read right when, can be because Linux files a1By
Lock and can not obtain, host process can only be waited to abandon to Linux files a1Exclusive lock, that is, wait host process terminate (i.e. extremely
Die) when, it can just get.
A2032, host process create Linux files a2。
Create Linux files a2, primarily to finger daemon is avoided during with the host process synchronization, erroneous judgement master
State of a process the occurrence of, such as, when host process does not set up and finished, erroneous judgement host process terminate, and in advance enter call out
Play and (draw and live) stage, etc..By to Linux files a2Deletion action is performed, finger daemon can clearly know this
The current state of host process, refers to step B2033.
A2033, host process are to Linux files b2Deleted, if deleting successfully, perform step A2035, if deleting
Failure, then perform step A2034.
A2034, after preset time, return perform step A2033, that is, wait preset time after, return perform step
A2033。
Wherein, the preset time can be depending on the demand of practical application.
A2035, host process read Linux files b1, i.e. host process trial acquisition Linux files b1Read right.
A2036, read Linux files b when host process1When, determine that finger daemon has terminated.
Because when host process reads Linux files b1When, then show that host process has got Linux files b1
Read right, and from step B2031, finger daemon is to Linux files b1Added exclusive lock, so, guard into
During the survival of journey, other processes are can not to obtain Linux files b1 read right, only when finger daemon terminates (i.e. extremely
