detailed description

In order to solve the following problems in the related art: when the cache partition becomes read-only or damaged, the cache partition cannot be used normally, and some operations of the user cannot be completed, so that the terminal device is in an abnormal state, and the user experience is poor; A method and apparatus for buffer partition reconstruction are further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that The embodiments described herein are merely illustrative of the disclosure and are not limiting of the disclosure.

The first embodiment of the present disclosure provides a method for buffer partition reconstruction. The process of the method is as shown in FIG. 1 and includes steps S102 to S104:

S102. When confirming that the cache partition of the terminal is in an abnormal use state, sending a command that triggers the terminal to restart.

S104: During the restart of the terminal, the cache partition is reconstructed to restore the cache partition to a normal usable state.

In the optional embodiment of the present disclosure, when the cache partition of the terminal is not working properly, the entire system of the terminal is restarted, and the cache partition is reconstructed during the restart process, so that the cache partition can be used normally. The function of repairing the cache partition during the simple terminal restart process is simple and easy to operate, and solves the following problems of the related technology: when the cache partition becomes read-only or damaged, the cache partition cannot be used normally, and thus some operations of the user cannot be completed. The terminal device is in an abnormal state, and the user experience is poor.

During use, it is usually found that the cache partition of the terminal can be used normally during use. In the case of normal use, the cache partition can write data. Therefore, it is confirmed that the cache partition of the terminal is abnormal. The process of using the state can be as follows: First, it is determined whether data can be written in the cache partition, wherein the write data includes: a write command, or a cache packet; in the case where the data cannot be written in the cache partition, the confirmation The cache partition of the terminal is in an abnormal use state; in the case where data can be written in the cache partition, it is confirmed that the cache partition is not damaged and can be used normally.

If it is confirmed that the cache partition of the terminal is in an abnormal use state, the cache partition is reconstructed during the restart of the terminal. When implemented, the cache partition can be formatted by calling the automatic formatting function to complete the reconstruction. Process, of course, the user can manually format the cache partition, but the manual formatting process is more complicated, and requires user hands-on operation, and the user experience is poor. Therefore, the process of formatting the cache partition by calling the automatic formatting function is performed. It is a relatively fast automated execution process with simple operation and good user experience.

When sending a restart command, the user may be performing some operations, if it is directly heavy at this time The terminal may cause the user to lose the content being operated. Therefore, in order to improve the user experience, before sending a command to trigger the terminal to restart, the user may also send a prompt message to prompt the user terminal to restart; Whether the trigger operation from the user is received within the time. The predetermined time can be set according to experience and operational requirements. For example, the experience shows that after the user sees a certain message, the operation response is 10 seconds, and the predetermined time can be set to 10 seconds.

If a triggering operation from the user is received within a predetermined time, the corresponding action is performed according to the triggering operation of the user, and the corresponding action includes: restarting the terminal immediately, or stopping the restarting of the terminal, or, for a fixed period of time (for example, 10 minutes) Then restart the terminal; if the trigger operation from the user is not received within the predetermined time, the terminal is directly determined to be restarted when the predetermined time arrives.

The second embodiment of the present disclosure further provides a device for reconfiguring a cache partition. The structure of the device is as shown in FIG. 2, and includes: a first sending module 10, configured to confirm that a cache partition of the terminal is in an abnormal use state. And sending a command for triggering the terminal to restart; the reconstruction module 11 is coupled to the first sending module 10, and is configured to rebuild the cache partition during the restarting of the terminal, so that the cache partition is restored to the normal usable state.

During the implementation, the reconstruction module 11 is configured to call the automatic formatting function to format the cache partition during the restart of the terminal to complete the reconstruction.

In use, it is usually that the user finds whether the cache partition of the terminal can be used normally during use, and in the case of normal use, the data can be written in the cache partition. Therefore, FIG. 3 shows the above device. A preferred structure diagram, the apparatus further includes: a first determining module 12, configured to determine whether data can be written in the cache partition; wherein the writing data comprises: a write command, or a cache data packet; the confirmation module 13, Coupling with the first judging module 12 and the first transmitting module 10, and setting to be unable to write data in the cache partition, it is confirmed that the cache partition of the terminal is in an abnormal use state.

FIG. 4 is a schematic diagram showing still another preferred structure of the above apparatus. On the basis of FIG. 3, the apparatus further includes: a second sending module 14 coupled to the confirming module 13 and configured to send a command to trigger the terminal to restart, Sending a prompt message to the user to prompt the user terminal to restart; The second determining module 15 is coupled to the second sending module 14 and configured to determine whether a triggering operation from the user is received within a predetermined time after the prompting information is sent to the user. The executing module 16 is coupled with the second determining module 15 to set In order to receive the triggering operation within the predetermined time, the corresponding action is performed according to the triggering operation of the user, and the corresponding action includes: restarting the terminal immediately, or stopping the restarting of the terminal; the first sending module 10, and the second determining module 15 Coupling, set to reset the terminal upon arrival of the predetermined time if no triggering operation is received within a predetermined time.

In the related art, the operation of restoring the factory settings often encounters some unrecoverable scenarios, for example, the partition written to the factory reset command is destroyed or becomes a read-only partition. For this situation, the third embodiment of the present disclosure provides a method for buffer partition reconstruction, by which the related factory resetting process is changed, and the normal operation of the production setting function is restored, and the usability is improved.

In the Android (Android) system persist (storage attribute value), cache (cache), system (system partition), userdata (user data) partition, etc. have created ext* file system, and then loaded. The native Android system generates a partition image of the created file system during the compilation phase, and then downloads it to the terminal device through burning.

If the partition is damaged, you need to download this partition image to the terminal device again via PC (personal computer). The process of restoring the factory settings is to initiate the factory reset behavior through the setup menu or the diag command. The framework receives the factory reset command and writes the recovery command to the cache partition file through the file system read and write mode. Then the system reboots into recovery mode, and the recovery mode receives the recovery command to execute the corresponding instruction. However, when the cache partition is damaged or becomes read-only, the behavior of restoring the factory settings is abnormally stopped, which causes a bad use of the function.

In this embodiment, when a cache partition or the like is damaged, a method of reconfiguring a file system partition without using the PC side is implemented, and the processing procedure of restoring the factory settings is changed, and the function of restoring the factory setting is performed normally. The process is as shown in FIG. 5, and includes the following steps S501 to S508:

S501: The user initiates the "system" from the normal booting setting interface or sending the extended diag command. Reset".

S502: The framework receives the system restart request, attempts to write the recovery instruction of the cache partition, and determines whether the write is successful. If yes, execute S508, otherwise, execute S503.

S503: If the access is abnormal, determine the cache partition mount attribute to check the cache partition loading.

S504: Set the shared imem (shared memory) flag bit or write a flag (identification) to the binary partition, prompting the user that the cache partition needs to be reconstructed, and a restart process is required.

S505: Initiating a device restart.

S506: The device bootloader (a small program before the operating system kernel runs) detects the cache corruption flag and erases the first two blocks (data blocks) of the cache partition.

S507: The device continues to boot to hlos (kernel). In the ramdisk (virtual memory disk) loading partition stage, the partition automatic formatting function is added, and the cache partition is formatted into an ext4 file system, and then mounted.

S508: The cache partition normally writes a recovery instruction, restarts the device into recovery mode, and erases data and cache partition data.

The fourth embodiment of the present disclosure provides a method for buffer partition reconstruction, which is applied in the process of system upgrade. Under normal circumstances, the system upgrade will write the upgrade data packet to the cache partition. When the system upgrade data packet cannot be written, it is determined that the cache partition is abnormal. You need to use the cache partition reconstruction method provided in this embodiment. The method of reconstructing the cache partition includes the following process:

(1) When receiving the upgrade data packet, try to put the upgrade data packet into the cache partition and determine whether the upgrade data packet can be written in the cache partition. If yes, execute (4), otherwise execute (2).

(2) The system that triggered the terminal restarts.

(3) During the restart process, the cache partition is formatted by calling the automatic formatting function.

(4) Write the upgrade packet again in the cache partition.

With this embodiment, the user can solve the problem that the system upgrade cannot be completed by a simple operation.
