Fig. 1 is the method flow diagram of plug-in download method provided in one embodiment of the invention.The present embodiment is inserted with this
Part method for down loading is applied to come in the terminal for being equipped with host application for example, alternatively, should applied to host is equipped with
It is illustrated in the terminal of program and nonhost application program.As shown in Figure 1, the plug-in download method includes：
Step 101, it when the second process requested downloads installation plug-in unit, detects in process ID file lock corresponding with the plug-in unit
Whether process ID is stored with.
Process ID file lock is used to lock to the process corresponding to the process ID of storage, and process ID is used to identify the process.
One plug-in unit corresponds to a process ID file lock, and the name of process ID file lock is usually related to plug-in unit, for example makes
Corresponding process ID file lock is named with the K values of plug-in unit.First download install the plug-in unit process usually require create with
The corresponding process ID file lock of plug-in unit, and process ID file lock is named according to scheduled naming rule, it needs to download later and be somebody's turn to do
Other processes of plug-in unit can find corresponding process ID file lock according to the title of process ID file lock.
Process ID is stored in process ID file lock, shows there is the process locked in process ID file lock.If into
Predetermined value (such as -1) is stored in journey ID file locks, then shows had the first process to install plug-in download, and
It normally exits, when the second process needs use the plug-in unit, installed plug-in unit can be directly used, without again
Download installation.
Step 102, when process ID file lock is stored with the process ID of the first process, according to the process ID of the first process to
Operating system is inquired the first process and be whether there is.
Under normal circumstances, the first process is when downloading installation plug-in unit, by the process ID write-in process ID text of the first process
Part is locked, and is locked by process ID file lock to the first process；First process is after download installs, by the process ID of the first process
It is wiped from process ID file lock, the first process is unlocked by process ID file lock.But if the first process midway is abnormal
Exit, then the process ID of first process it is possible that can be retained in process ID lock in, do not wiped in time.
When the process ID that the first process is stored in process ID file lock, the second process will continue to according to the first process ID
The first process is inquired to operating system whether there is, so that it is determined that whether the first process is in normal operating condition.If first
Process exists in an operating system, then shows that the first process is in normal operating condition, the second process exits；If the first process
It is not present in an operating system, then shows that the first process is exited in midway exception, enter step 103.
Step 103, it in the absence of the first process, determines that the first process exception exits, will be stored in process ID file lock
Process ID be revised as the process ID of the second process.
When the first process exits, either normally exit or it is abnormal exit, all inquired in operating system less than this
One process.
Therefore, if the process ID in process ID file lock exists, but the second process is looked into according to the process ID to operating system
It askes to the first process and is not present, then show that exception exits the first process in midway.
Second process overrides the first process stored originally by the process ID write-in process ID file lock of the second process
Process ID, then process ID file lock the first process is unlocked, again to the second process lock.
Step 104, the download installation procedure of the plug-in unit is continued to execute.
Since the first process exits extremely, the partial data of plug-in unit may be downloaded, therefore in the second process
After lock, it can continue to download and the plug-in unit be installed according to the data downloaded, without all re-downloading the plug-in unit.
In conclusion plug-in download method provided in an embodiment of the present invention, writes by using by the process ID of the first process
The mode for entering process ID file lock locks to the first process so that needs the second process for downloading same plug-in unit can be according to process
The first process is searched in process ID to operating system in ID file locks to whether there is, if being not present, has shown the first process
In midway, exception exits, then the process ID of the second process is written again and locks, continue to execute the download installation procedure of plug-in unit, keep away
After the first process exception for having exempted to lock exits, other second processes are suspended and can not continue to execute the download installation of plug-in unit
The situation of flow, so as to solve the problems, such as that file lock of the prior art can deadlock.
Fig. 2A is the method flow diagram of plug-in download method provided in another embodiment of the present invention.The present embodiment is with this
Plug-in download method is applied to come in the terminal for being equipped with host application for example, alternatively, applied to host is equipped with
It is illustrated in the terminal of application program and nonhost application program.As shown in Figure 2 A, which includes：
Step 201, when the second process requested downloads installation plug-in unit, whether application program corresponding with the second process is detected
For host application.
Since host application has the permission for downloading installation plug-in unit, nonhost application program does not have download installation and inserts
The permission of part.Therefore when the second process asks to download installation plug-in unit to operating system, operating system first determines the second process pair
Whether the application program answered is host application, and the permission for installing the plug-in unit is downloaded to determine whether the second process has.
Step 202, when application program corresponding with the second process is host application, whether the plug-in unit is detected
In host application.
When the corresponding application program of the second process is host application, show that the second process has plug-in download installation
Permission.At this point, operating system, which allows the second process to download, installs the plug-in unit.Before the plug-in unit is installed in download, the second process
Detect whether the plug-in unit is already installed in host application；When detecting that the plug-in unit is already installed in host application
When, the second process can directly use the plug-in unit.
When plug-in unit is not yet mounted in host application, then step 203 is performed.
Step 203, it when the plug-in unit is not yet mounted in host application, detects whether to exist corresponding with the plug-in unit
Process ID file lock.
Since a plug-in unit corresponds to a process ID file lock, the second process detection whether there is and the plug-in unit pair
The process ID file lock answered；If there is no process ID file locks corresponding with the plug-in unit, 204 are entered step；If in the presence of with this
The corresponding process ID file lock of plug-in unit, then enter step 205.
Step 204, when there is no during process ID file lock corresponding with the plug-in unit, creating process ID file lock, and by the
The process ID file lock that the process ID write-in of two processes creates performs the download installation procedure of plug-in unit.
When there is no during process ID file lock corresponding with the plug-in unit, showing that the plug-in unit was not downloaded, therefore second
Process creation process ID file lock corresponding with plug-in unit, and name the process ID file lock according to scheduled naming rule.Process
The name of ID file locks is usually related to plug-in unit, for example corresponding process ID file lock can be named using the K values of plug-in unit.
The process ID file lock pair is written after process ID file lock is created, by the process ID of the second process in second process
Second process is locked.
Step 205, when there is process ID file lock corresponding with the plug-in unit, process ID text corresponding with the plug-in unit is detected
Whether process ID is stored in part lock.
Process ID file lock is used to lock to the process corresponding to the process ID of storage, and process ID is used to identify the process.
If process ID file lock exists, show that the plug-in unit was downloaded or had been downloaded, if the first process is normal
The download installation procedure of plug-in unit is performed, the first process can delete the process in the process ID file lock when the first process exits
Process ID is revised as predetermined value (such as -1) by ID, therefore, if not having process in the second process detection to process ID file lock
ID is stored with predetermined value, then shows had the first process to install the plug-in download, and normally exit, when second
When process needs use the plug-in unit, mounted plug-in unit can be directly used, without downloading installation again.
Step 206, when process ID file lock is stored with the process ID of the first process, according to the process ID of the first process to
Operating system is inquired the first process and be whether there is.
Under normal circumstances, the first process is when downloading installation plug-in unit, by the process ID write-in process ID text of the first process
Part is locked, and is locked by process ID file lock to the first process；First process is after download installs, by the process ID of the first process
It is wiped from process ID file lock, the first process is unlocked by process ID file lock.But if the first process midway is abnormal
Exit, then the process ID of first process it is possible that can be retained in process ID lock in, do not wiped in time.
When the process ID that the first process is stored in process ID file lock, the second process will continue to according to the first process ID
The first process is inquired to operating system whether there is, so that it is determined that whether the first process is in normal operating condition.If first
Process exists in an operating system, then shows that the first process is in normal operating condition, the second process exits；If the first process
It is not present in an operating system, then shows that the first process is exited in midway exception, enter step 207.
Step 207, it in the absence of the first process, determines that the first process exception exits, will be stored in process ID file lock
Process ID be revised as the process ID of the second process.
After the locking of the first process, moved back if the first process is abnormal during plug-in download installation procedure is performed
Go out, since the first process fails to perform the operation that the process ID in process ID file lock is deleted or modified, lead to process ID file
Process ID in lock still remains, therefore process ID file lock is still the state of locking, but the download installation procedure of plug-in unit be by
It interrupts.
When the first process exits, either normally exit or it is abnormal exit, all inquired in operating system less than this
One process.Therefore, if the process ID in process ID file lock exists, but the second process is inquired according to the process ID to operating system
It is not present to the first process, then shows that the first process exception exits.
Second process overrides the first process stored originally by the process ID write-in process ID file lock of the second process
Process ID, then process ID file lock the first process is unlocked, again to the second process lock.
Step 208, the download installation procedure of the plug-in unit is continued to execute.
Since the first process exits extremely, the partial data of plug-in unit may be downloaded, therefore in the second process
After lock, the second process can continue to download and install the plug-in unit according to the data downloaded, without all re-downloading
The plug-in unit.
Optionally, the second process continues to execute the download installation procedure of plug-in unit, the step of can including as shown in Figure 2 B：
Step 208a obtains the plug-in download installation progress of the first process by shared drive.
Shared drive is the memory space that the first process and the second process realize interprocess communication.
Shared drive is a kind of realization method in realization inter-process communication mechanisms between the different processes of operating system.
During the download installation procedure for performing plug-in unit, the download of plug-in unit can be installed into first process by the first process
Degree is stored to shared drive, and when the first process exception exits, the second process can be to getting the first process in shared drive
Plug-in unit download installation progress.
Step 208b continues to download and installs the plug-in unit according to the plug-in download installation progress of acquisition.
Second process can continue to download after the download installation progress of plug-in unit is got according to the data downloaded
Plug-in unit is installed.Such as first process exited extremely when plug-in download is to 50%, the second process then can be after 50% continues download
The data in face.
The download installation progress of the plug-in unit is recorded in shared drive step 208c.
Second process perform plug-in unit download installation procedure when, also can simultaneously by the download installation progress of plug-in unit store to
Shared drive.
Optionally, when third process requested downloads installation plug-in unit, if third process detection is carrying out to the second process
The download installation procedure of plug-in unit, then third process by accessing shared drive, install by the download that can efficiently get plug-in unit
Progress.
If the second process has normally performed the download installation procedure of plug-in unit, the second process can be to process ID file lock solution
Lock.Optionally, the second process is completed to unlock by way of step 209 or step 210.
Step 209, when download installation procedure is finished, the process of the second process in deletion process ID file locks
ID。
Process ID in second process-kill process ID file lock.
Step 210, when download installation procedure is finished, the process ID of the second process in process ID file lock is repaiied
It is changed to predetermined value.
Process ID in second process modification process ID file lock, i.e., be revised as predetermined value, which uses by process ID
Installation procedure is downloaded in expression to be finished.Optionally, which is a process ID value not actually existed, such as-
