Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Socket (Socket) communication is an Inter-Process Communication (IPC) mechanism. In the operating system, a set of Application Programming Interface (API) is usually provided for applications, called sockets. Socket API. The application program can use the network socket through the socket interface for data exchange. Based on the socket address, the operating system can decide that the data should be delivered to a specific process or thread. In Socket communication, HTTP provides a specific form of encapsulating or displaying data, and Socket provides the capability of network communication.

Binder communication is similar to Socket communication. It is an efficient inter-process communication mechanism that can send data from process A to process B. At present, more and more terminal devices also communicate based on the Binder communication mechanism. For example, terminal devices include external storage device management modules (Volume Daemon, Vold) and storage management service modules (Storage Manager Service). When a memory card, U disk, etc. are mounted, an interaction between an external storage device management module and a storage management service module is required, and the interaction may be based on Binder communication. Among them, terminal equipment includes but is not limited to mobile phones, digital cameras, portable computers and other terminal equipment.

However, the inventor found in the research that the external storage device management module and the storage management service module based on the Binder communication in the process of mounting the external storage device, if they get stuck during the Binder call, it may trigger the watchdog in the system The program causes the system to become unresponsive, and abnormal situations such as system stuck or fixed screen appear.

Therefore, in order to solve the foregoing defects, an embodiment of the present application provides a mounting processing method, as shown in FIG. 1, specifically, the method includes: S101 to S104.

S101: The storage management service module sends a first call instruction to the external storage device management module.

In this embodiment, the terminal device includes an external storage device module and a storage management service module. The external storage device management module is the management and control center of the external storage system in the operating system platform, and is the backend that manages and controls the external storage device of the operating system platform. process. Its functions mainly include: external storage device plug-in event detection, external storage device mounting, unmounting, formatting, etc. The storage management service module is a module that communicates between the system framework layer of the operating system and the external storage device management module. At the same time, the storage management service module is also a module that provides application programs with storage device access interfaces and storage device mounting message broadcasting. It should be noted that the external storage device management module and the storage management service module are based on inter-process communication. If the communication process between the two is stuck, the system may become unresponsive.

Among them, after the external storage device is inserted into the terminal device, the terminal device needs to mount the external storage device, and after the mounting is successful, the application on the terminal device can access the external storage device.

In an implementation manner, when the terminal device needs to mount the external storage device, the storage management service module sends the first call instruction to the external storage device management module.

S102: In response to the first calling instruction, the external storage device management module executes a detection operation, and sets the detection status flag of the external storage device as the detection status flag, and returns the detection status flag.

Among them, the detection operation is to detect whether the file system of the external storage device is abnormal.

Wherein, the detection flag is used to indicate that the storage management module external storage device management module is performing a detection operation and the detection is not completed, so that when the external storage device management module returns the detection status flag, the storage management module is the detection flag based on the detection status flag , You can know that the external storage device is being detected and not completed. Specifically, after the terminal device detects the insertion event of the external storage device, the external storage device management module creates the external storage device and correspondingly stores the device information of the external storage device, where the device information includes the detection status identifier.

In some embodiments, the detection time length includes the time consumed for detecting whether the file system is abnormal and the time consumed by the external storage device management module to repair when the file system is abnormal. For example, the file system of the external storage device is damaged too much, which may cause the external storage device management module to try to repair the file system of the external storage device for a long time, and the long repair time will cause the system to get stuck.

In this embodiment, in response to the first call instruction, the external storage device management module performs detection operations respectively, and sets the detection status flag of the external storage device as the detection status flag, and returns the detection status flag, so that the external storage device management module and The interaction process based on the first call instruction of the storage management service module can end without waiting for the detection operation to complete, which avoids the interaction process based on the first call instruction being stuck due to the detection time being too long, causing the system to become unresponsive. Specifically, the system Unresponsiveness includes system abnormalities such as system stuck or fixed screen (the screen is stuck for a long time, also called frozen screen or hang), which can prevent abnormal external storage devices from being inserted and cause the system to become unresponsive and improve system stability .

Specifically, for example, in response to the first call instruction, the external storage device management module may set the detection status flag of the external storage device to the detection flag such as "checking". After the external storage device management module returns "checking", the storage management The service module can know that the external storage device is being checked according to the storage status of the external storage device as "checking".

S103: The external storage device management module sends a detection completion instruction to the storage management service module when the detection operation is completed.

In this embodiment, when the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module to notify the storage management service module that the detection operation of the external storage device has been completed, so that the storage management service module can perform Next step.

As an implementation manner, if the detection duration of the detection operation exceeds the specified time, the detection operation is ended. At this time, the detection operation is completed, and the external storage device management module sends a detection completion instruction to the storage management service module. It should be noted that when the file system of the external storage device is abnormal, the external storage device management module attempts to repair the file system. If the repair time is too long and the detection time before the repair is successful has exceeded the specified time, Then, when the detection operation is completed, the file system of the external storage device is still abnormal. That is, when the detection operation is completed, the file system of the external storage device may be abnormal or non-abnormal. Among them, the non-abnormal situation includes a situation where the file system was normal before detection, and a situation where the external storage device was abnormal when it was first inserted, but was restored to normal after the external storage device management module was repaired within a specified time.

As another embodiment, if the detection time of the detection operation exceeds the specified time, the detection operation is not considered to be completed, that is, if the detection time is too long and the detection operation is not completed within the specified time, the detection operation is considered to be incomplete, and the storage is not The management service module sends a detection completion instruction, so that the storage management service module cannot perform the next operation on the external storage device. Specifically, because the file system of the external storage device is damaged too much, the external storage device management module cannot complete the repair of the damaged file system within the specified time.

It should be noted that because the external storage device management module has completed a return in response to the first call instruction, that is, the current calling thread has ended, and the detection operation performed by the external storage device management module on the external storage device is not based on The thread of cross-process communication between storage management service modules is based on the internal process of the external storage device management module. Therefore, even if the detection time is too long, the system process will not be stuck, and the system will not be unresponsive. Thereby, it can prevent the system from jamming or freezing the screen caused by the abnormal external storage device inserted into the terminal device, and improve the system stability.

S104: The storage management service module notifies the external storage device management module to mount the external storage device based on the detection completion instruction.

Among them, the storage management service module can learn that the detection operation has been completed based on the detection completion instruction, and at this time notify the external storage device management module to mount the external storage device.

Therefore, compared with the prior art that the external storage device management module needs to complete the detection operation and the mounting operation before returning, this embodiment separates the execution of the detection operation from the mounting operation, so that the external storage device management module Before the detection operation is completed, return the detection status flag to end the cross-process communication thread with the storage management service module, and mount it after the detection operation is completed. Therefore, it can prevent the detection time of the external storage device from being long If it is too long, the thread will get stuck and the system will become unresponsive, which can prevent abnormal situations such as system stuck or fixed screen caused by abnormal external storage device insertion, and improve system stability.

Please refer to FIG. 2, which shows a mounting processing method provided by an embodiment of the present application. Specifically, the method includes: S201 to S207.

S201: The storage management service module sends a first calling instruction to the external storage device management module.

As an implementation manner, the first call instruction includes a detection instruction. Specifically, the detection instruction may be a function Check used to detect whether the file system is abnormal and whether there is an error, or may be another interface used to detect whether the file system is abnormal. Function, this embodiment does not limit this. Based on the detection instruction, operations such as setting or updating the detection status flag can also be performed. In this embodiment, the storage management service module sends the detection instruction to the external storage device management module through the Binder call. Specifically, the storage management service module calls the function Check to the external storage device management module based on Binder communication, so that the external storage device management module can execute the function Check. Thus, based on Binder communication, cross-process calling functions can be easily realized.

As another implementation manner, the detection instruction may be pre-loaded, that is, the first call instruction does not include the detection instruction. At this time, the storage management service module sends the first call instruction to the external storage device management module to enable the external storage device management In response to the first call instruction, the module can execute pre-loaded detection instructions, reduce the amount of communication data between processes, reduce function loading time, improve communication efficiency, improve detection efficiency, and thus help improve the efficiency of mounting external storage devices.

S202: In response to the first calling instruction, the external storage device management module performs a detection operation, and sets the detection status flag of the external storage device as the detection status flag, and returns the detection status flag.

Wherein, the detection status flag can be a flag bit corresponding to the external storage device used to reflect the current detection status. Through the flag bit, the current detection status can be known. For example, if the flag bit is a flag during detection such as "Checking", you can Indicates that the external storage device management module is performing a detection operation on the external storage device and the detection is not completed. The storage management service module can learn that the current detection status is the detection operation being performed and the detection is not completed by receiving the detection status identifier returned by the external storage device management module carry out.

In this embodiment, in response to the first call instruction, the external storage device management module may perform the detection operation and set the detection status flag of the external storage device based on two different threads, and return the detection status flag. Specifically, in response to the first call instruction, the external storage device management module sets the detection status flag of the external storage device as the detecting flag based on the first thread, and returns the detection status flag, so that the first thread will receive the first call instruction The execution is returned immediately, and the external storage device management module responds to the first call instruction to execute the detection operation based on the second thread.

Among them, the first thread is a cross-process thread based on the Binder call, that is, the main thread, and the second thread is a thread within the process of the external storage device management module. Therefore, in this embodiment, the first thread is used to receive the first call. After the instruction, immediately return to the end of execution, so that the thread called by the Binder can end in time, and start the second thread to perform the actual detection operation, so that the actual detection time, and the repair time included therein does not affect the main thread, that is Performing detection operations based on the second thread that may cause the Binder call to be stuck, so that the first thread based on the Binder call can get a timely or even quick response, which can well avoid the system unresponsive due to the long detection time and prevent abnormalities Abnormal situations such as system stuck or fixed screen caused by the insertion of external storage devices have greatly improved the stability of the system.

As an implementation manner, the first process is performed before the second process. Specifically, in response to the first call instruction, the external storage device management module first sets the detection status flag as the detection status flag based on the first thread, and returns the detection status flag At this time, the second thread is started, and the detection operation is performed based on the second thread.

As another implementation manner, the first process and the second process are performed at the same time. Specifically, the external storage device management module responds to the first call instruction to simultaneously set the detection status flag and start the second thread and perform the detection operation based on the second thread , The detection status identification can be returned immediately before the detection operation is completed, and because the second thread and the first thread are performed at the same time, the external storage device management module responds to the first call instruction, and on the basis of ending the Binder call in time, The detection operation can be performed faster and the detection efficiency can be improved. At the same time, the higher detection efficiency is also conducive to improving the mounting efficiency of the external storage device.

Among them, the detection operation is to detect whether the file system of the external storage device is abnormal, and to repair the abnormal file system. It should be noted that the detection operation includes the operation of repairing the abnormal file system when an abnormality is detected. Therefore, in this embodiment, the detection duration includes the repair duration. Specifically, if the file system is damaged, it is abnormal, and if there is no damage, it is normal, and the external storage device management module will try to repair the abnormal file system when it is abnormal. Further, if the repair is completed, the file system is not damaged at this time, and it can be considered that it is normal without exception.

In some embodiments, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation is completed, and if the file system is abnormal and the repair is not completed, the file system is still in an abnormal state, and the external storage The device management module determines that the detection operation is not completed. among them:

As a way, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation is completed; if the file system is abnormal and cannot be repaired, the external storage device management module determines that the detection operation is not completed. Therefore, there is no time limit for the detection operation, and when the file system is abnormal, it is determined that the detection operation is not completed. Therefore, when the repair is completed, it can be determined in time that the detection operation has been completed for the next step.

As another way, the detection operation of the external storage device management module is correspondingly set with a preset duration, and when the file system is abnormal and the repair is not completed within the preset duration, that is, when the detection duration exceeds the preset duration, it is determined that the detection operation is not successful. carry out. Specifically, if it is detected that the file system is normal and no repair is required at this time, the external storage device management module determines that the detection operation has been completed; if the file system is detected to be abnormal but the repair is completed within the preset time period, the external storage device management module determines the detection operation Completed; if the detection time exceeds the preset time but the repair is still not completed, the external storage device management module detects an abnormal file system at this time, but the file system damaged within the preset time has not been repaired, it is determined that the detection operation is not completed . In this way, the execution time of the detection operation can be controlled, and a response can be made in time for the next operation, so as to ensure the detection efficiency while avoiding the detection timeout and no response, and improving the system availability.

In other embodiments, the detection operation of the external storage device management module is correspondingly set with a preset duration, and when the file system is abnormal and the repair is not completed within the preset duration, that is, when the detection duration exceeds the preset duration, the detection is still determined The operation is complete. Specifically, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation has been completed, and if the file system is abnormal and the repair is not completed within the preset time period, the file system is still in an abnormal state, At this time, the external storage device management module still determines that the detection operation is complete. That is, the detection operation can be performed for a preset duration at most, and when the preset duration is reached, it is determined that the detection operation has been completed. At this time, the file system may be normal or abnormal. As a result, the execution time of the detection operation can be controlled, and the detection operation is determined to be completed when the file system is not repaired, and a timely response can be made to proceed with the next operation, thereby ensuring the detection efficiency while avoiding detection timeout and unresponsiveness, improving System availability.

Further, when the detection duration exceeds the preset duration, the external storage device management module may terminate the detection operation or not. The specific implementation manner is as follows:

In an implementation manner, when the detection duration exceeds the preset duration, the external storage device management module can terminate the detection operation, save resources, and improve system availability.

In another embodiment, when the detection duration exceeds the preset duration, the external storage device management module may not terminate the detection operation, so that the detection operation can continue. Specifically, when the file system is damaged too much, the external storage device management module requires It takes a long time to complete the repair of all abnormal file systems, and the required time may exceed the preset time. At this time, the external storage device management module is enabled by not interrupting the detection operation when the detection time exceeds the preset time. The repair can be continued. Therefore, there is a possibility of completing the repair before the mounting operation is performed. At this time, the external storage device whose detection operation is not completed still has the possibility of being successfully mounted. For specific implementation manners, reference may be made to the following embodiments, and details are not described in this embodiment.

Further, in this embodiment, when the detection duration exceeds the preset duration, S204 may be executed; when the detection duration does not exceed the preset duration, S203 may be executed.

S203: When the detection time period exceeds the preset time period, the external storage device management module sets the detection status flag as a detection abnormality flag.

Wherein, the detection status identifier also includes a detection abnormality identifier, which can be used to indicate that the storage management service module currently detects an abnormality, that is, the detection time exceeds a preset time and the repair is not completed, and the file system of the external storage device is still abnormal.

In this embodiment, when the detection duration exceeds the preset duration, the external storage device management module sets the detection status flag as the detection abnormality flag. Specifically, in one embodiment, the detection abnormality identifier may be a string of numbers, letters, words, etc., such as "0", "uncheckable", etc., used to indicate that the file system is still abnormal after the detection operation, and may be preset by the system. Yes, it can also be customized, so that the abnormality of the file system can be learned through the abnormality detection identifier. In addition, this embodiment does not make other restrictions on the naming form of the abnormality detection identifier.

Because the external storage device is difficult to mount successfully when the file system is abnormal, when the file system is abnormal and the repair is not completed within the preset time, by setting the abnormal detection flag, the external storage device can be ignored when the abnormal detection flag is detected. Mount it to reduce unnecessary resource consumption and improve response efficiency. Specific implementation manners can be seen in the following embodiments, which are not repeated here.

S204: The external storage device management module sends a detection completion instruction to the storage management service module when the detection operation is completed.

In this embodiment, when the detection operation is completed, the file system of the external storage device may be normal or abnormal, and the normal includes the normal condition itself and the abnormal but the repair completed condition.

As an implementation manner, if the file system is abnormal and the repair is not completed within the preset time, that is, when the detection time exceeds the preset time, it is still determined that the detection operation has been completed, and at this time, the external storage device management module sends to the storage management service module The detection completion instruction allows the storage management service module to learn that the current external storage device has completed the detection operation by receiving the detection completion instruction and can be mounted. At this time, the file system of the external storage device may be abnormal or non-abnormal.

As another embodiment, if the file system is abnormal and the repair is not completed within the preset time, that is, when the detection time exceeds the preset time, it is determined that the detection operation is not completed, and at this time, the external storage device management module sends to the storage management service module The detection completion instruction enables the storage management service module to learn that the current external storage device is normal and can be mounted by receiving the detection completion instruction. At this time, the file system of the external storage device is non-abnormal, that is, when the file system of the external storage device is still abnormal, the detection completion command is not sent.

S205: The storage management service module notifies the external storage device management module to mount the external storage device based on the detection completion instruction.

In this embodiment, based on the detection completion instruction, the storage management service module can determine that the current external storage device has completed the detection operation and can be mounted, and then notifies the external storage device management module to mount the external storage device. Therefore, the detection operation and the mounting operation are performed in different threads separately, and the file system of the external storage device is determined to be normal through the detection operation, and the mounting is performed, which can improve the success rate and efficiency of the mounting.

S206: When the external storage device management module mounts the external storage device, it is determined whether the detection abnormality identifier can be found.

In some embodiments, if the file system is abnormal and the repair is not completed within the preset time, that is, when the detection time exceeds the preset time, it is still determined that the detection operation has been completed, and the external storage device management device management module mounts the external storage device When determining whether the detection abnormality flag can be found, specifically, for example, based on the flag bit that characterizes the detection state, it is determined whether the detection status flag on the flag bit is the detection abnormality flag; for example, it can directly search for the corresponding external storage device Whether to store the detection abnormality identifier.

In other implementations, if the file system is abnormal and the repair is not completed within the preset time, that is, when the detection time exceeds the preset time, it is determined that the detection operation is not completed, and S206 to S207 are not executed after S205. At this time, the external The file system of the storage device is non-abnormal, so there is no need to find and detect the abnormal identifier.

Further, if the detection abnormality identifier can be found, S207 can be executed; if not, the mounting operation can be continued.

S207: If yes, stop mounting the external storage device.

If the detection abnormality identification can be found, the external storage device management module determines that the file system of the external storage device is abnormal. By stopping the mounting of the external storage device, the consumption of operating resources can be reduced, the efficiency of system operation can be improved, and it is beneficial. Improve mounting efficiency.

It should be noted that, for the parts that are not described in detail in the foregoing steps, reference may be made to the foregoing embodiments, and details are not described herein again.

The mounting processing method provided in this embodiment separates the detection operation and the mounting operation in different threads for execution, and the external storage device management module returns immediately after receiving the first call instruction so that the thread called by the Binder can be End in time, and start the second thread to perform the actual detection operation, so that the actual detection time, and the repair time included therein does not affect the main thread, that is, the detection operation that may cause the Binder call to be stuck based on the second thread execution, avoids The system does not respond due to the long detection time, which prevents abnormal situations such as system jam or fixed screen caused by abnormal external storage device insertion, and greatly improves the stability of the system. Moreover, by determining whether the detection abnormality identification can be found, the external storage device management device can continue to mount when the file system of the external storage device is non-abnormal, which can also improve the success rate and efficiency of the mount. In addition, due to the external storage device The management module does not mount when the file system is abnormal, which can also reduce unnecessary resource consumption and improve system operating efficiency.

In addition, when the detection duration exceeds the preset duration, this method can also be ended without performing the next step. Specifically, referring to FIG. 3, the method includes: S301 to S303.

S301: The storage management service module sends a first call instruction to the external storage device management module.

S302: In response to the first calling instruction, the external storage device management module executes a detection operation, and sets the detection status flag of the external storage device as the detection status flag, and returns the detection status flag.

S303: When the detection time length exceeds the preset time length, the external storage device management module sets the detection status flag as a detection abnormality flag.

In this embodiment, when the detection time exceeds the preset time, the method ends, so that when the file system is abnormal and the repair is not completed within the preset time, the storage management service module is not notified to end the method, which can greatly Reduce the consumption of operating resources and improve system operating efficiency.

Further, as a way, when the detection duration exceeds the preset duration, S303 may be executed first, and then this method is ended. At this time, the external storage device management module sets the detection status flag as the abnormal detection flag, so that when the storage management service module obtains the detection status flag of the external storage device, it can learn that the file system of the external storage device is in an abnormal state, so that the user can timely Try to mount again.

As another way, when the detection duration exceeds the preset duration, S303 may not be executed, and this method is ended. At this time, the storage management service module considers that the external storage device is always being detected and is still performing a detection operation.

If it is not abnormal, the external storage device management module detects that the file system of the external storage device is not abnormal at this time, and the external storage device management module performs a mounting operation on the external storage device and obtains the mounting result. Specifically, the external storage device management module is based on a mounting instruction, such as a function Mount for mounting, and by executing the function Mount, a mounting operation is performed on the external storage device to obtain a mounting result. Among them, the mounting result includes mounting success and mounting failure.

S507: The external storage device management module sets a mounting status flag according to the mounting result.

Specifically, the mounting status flag may be a flag bit used to characterize the mounting status.
