Generally, before the electronic device is shipped, basic function tests are performed on the unassembled electronic device in batch to determine whether the electronic device meets the shipping standards. The basic function test can comprise parameter calibration, current test, comprehensive test and the like; in practical situations, in order to seek higher efficiency, after the electronic equipment is tested on a test production line, the power supply of the electronic equipment is usually directly cut off, and the next processing is not performed after each piece of electronic equipment is normally shut down; therefore, the electronic device which is abnormally powered down can damage the running file system to a certain extent, and the electronic device cannot be started.
In order to solve the problem of file system abnormality caused by abnormal power failure on a test production line, the embodiment of the invention provides a method for processing file system abnormality.
Fig. 1 is a schematic flowchart of a processing method for a file system exception according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
Wherein the unloading instruction is issued by the control device when the pre-assembly test for the electronic device is completed.
In other embodiments of the present invention, the receiving of the uninstalling instruction for the file system from the control device in step 101 may be implemented by the electronic device; here, the electronic apparatus may be an apparatus including at least a CPU and a storage device; in practical applications, the electronic device may include: smart phones, tablet computers, computer devices, and the like, as the present invention is not limited thereto. The control device may be a device that controls the electronic device to perform a test; in practical applications, the control device may include: personal Computers (PCs), and the like.
In step 101, a communication connection may be established between the control device and the electronic device through a data line, or may be established in a WiFi or bluetooth manner, in this embodiment, the main function of the communication connection includes, but is not limited to, implementing transmission of control signals and data of the control device to the electronic device, and may also be used to implement transmission of information and data of the electronic device to the control device. The control device may include a display screen for displaying relevant information of the electronic device during the test process, for example, information of a test process, a test result, an uninstall process, an uninstall result, and the like of the electronic device may be displayed.
The file system is used for organizing and distributing the space of storage equipment in the electronic equipment, is responsible for storing files and protecting and retrieving the stored files; for example, a file system refers to a system that titles files and indicates where the files are located for storage and retrieval. Before using the file system, the file system needs to be connected with a preset directory in the electronic device to establish a mapping relationship. Therefore, the electronic device reads the file system by reading the data in the preset directory.
The unloading instruction is used for unloading a file system in the electronic equipment; wherein the uninstalling instruction is issued by the control device after the control device completes the test of the electronic device. Specifically, the electronic device sends test completion information to the control device after the test is completed, and the control device sends an unloading instruction to the electronic device after receiving the test completion information.
102, unloading the file system in the electronic equipment based on the unloading instruction to avoid the abnormal situation of the file system.
Specifically, before the electronic device is assembled and shipped out of a factory, the control device controls the electronic device to perform various types of tests; normally, after the test is completed, the control device directly cuts off the power supply of the electronic device to complete the test procedure; however, in this embodiment, after the electronic device completes the test, the file system in the electronic device needs to be unloaded, and after the unloading is completed, the control device directly cuts off the power supply of the electronic device.
In other embodiments of the present invention, the electronic device unloads the file system in the electronic device based on the unload instruction. Here, step 102 may include:
step 102a, the electronic device traverses the target file to obtain a mount point directory of the file system in the target file.
Wherein the file system is loaded under a preset directory in the target file.
Here, the electronic device may read all file systems in the electronic device through the object file. That is, the target file may contain information of all file systems in the electronic device. In this embodiment, the target file may include a readable and writable partition; for example, the object file may include/proc/mounts. It should be noted that, an operating system of the electronic device may regard all resources in the electronic device as files, so that the resources of the whole electronic device may be integrated into a large file directory; when we need to access a system file, the system file must be connected to a directory already existing in the electronic device, and then the file system is accessed by accessing this directory.
The mount point is an entry directory of the file system, where mount is a process of associating the file system with a preset directory in the target file, that is, a process of establishing a mapping relationship between the file system and the preset directory. All file systems in the electronic equipment are mounted under the preset directory in the readable and writable partition, namely all the file systems in the electronic equipment are connected with the preset directory in the readable and writable partition.
And 102b, the electronic equipment deletes the mount point directory corresponding to the file system in the target file.
The electronic device can transfer the mount point directory in the acquired target file to the function by calling the umount function, so as to achieve unloading of the file system.
The file system exception handling method provided by the embodiment of the invention comprises the steps of firstly receiving an unloading instruction aiming at a file system sent by a control device, wherein the unloading instruction is sent by the control device when the test aiming at a mainboard of electronic equipment before assembly is finished, and then unloading the file system in the electronic equipment based on the unloading instruction; therefore, after the electronic equipment is tested and before the electronic equipment is powered off, the file system on the disk partition inside the electronic equipment is unloaded, so that the file system is deleted before the electronic equipment is powered off abnormally.
Based on the foregoing embodiments, an embodiment of the present invention provides a method for handling a file system exception, as shown in fig. 2, where the method includes the following steps:
The unloading instruction is used for unloading the file system in the electronic equipment so as to avoid the abnormality of the file system.
When the test before assembling for the electronic device is completed in step 201, sending an unloading instruction for the file system to the electronic device may be implemented by the control device; the control device may be a device that controls an electronic device to perform a test; in practical applications, the control device may include: personal Computers (PCs), and the like.
In some embodiments, step 201 may be preceded by receiving test completion information sent by the electronic device.
In other embodiments of the present invention, the control device and the electronic device may establish a communication connection through a data line, or may establish a communication connection through WiFi or bluetooth, in this embodiment, the main function of the communication connection includes, but is not limited to, implementing transmission of control signals and data of the control device to the electronic device, and may also be used to implement transmission of information and data of the electronic device to the control device. The control device may include a display screen for displaying relevant information of the electronic device during the test process, for example, information of a test process, a test result, an uninstall process, an uninstall result, and the like of the electronic device may be displayed.
According to the file system exception handling method provided by the embodiment of the invention, when the test before the electronic equipment is assembled is finished, an unloading instruction aiming at the file system is sent to the electronic equipment; the unloading instruction is used for unloading a file system in the electronic equipment so as to avoid the file system from being abnormal; therefore, after the electronic equipment is tested and before the electronic equipment is powered off, the control equipment indicates the electronic equipment to unload the file system on the disk partition inside the electronic equipment, so that the file system of the electronic equipment is deleted before abnormal power failure, the file system on the disk partition can be prevented from being damaged under the condition of abnormal power failure, the probability of damage of the file system can be effectively reduced, and the normal starting of the electronic equipment is ensured.
Based on the foregoing embodiments, an embodiment of the present invention provides a method for handling a file system exception, as shown in fig. 3, where the method includes the following steps:
step 301, when the control device completes the test before assembling the electronic device, sending an uninstalling instruction for the file system to the electronic device.
The unloading instruction is used for unloading the file system in the electronic equipment so as to avoid the abnormality of the file system.
Step 302, the electronic device receives an uninstall instruction for the file system from the control device.
Wherein the unloading instruction is issued by the control device when the pre-assembly test for the electronic device is completed.
Step 303, the electronic device traverses the target file to obtain a mount point directory of the file system in the target file.
Wherein the file system is loaded under a preset directory in the target file. Here, the target file includes a readable and writable partition; correspondingly, all file systems in the electronic equipment are mounted in the preset directory in the readable and writable partition.
And step 304, the electronic equipment deletes the mount point directory corresponding to the file system in the target file.
Step 305, if the electronic device fails to unload the file system, sending a result of the failure to unload the file system in the electronic device to the control device, so that the control device processes the electronic device without unloading the file system.
The failure of unloading the file system in the electronic device at least comprises that the unloading of the file system is not finished within a preset time.
Here, the preset time may be a maximum duration for executing the uninstalling of the file system, which is set by the control device, and in a process of executing the uninstalling instruction, an unresponsive condition, that is, a crash condition, of the electronic device may inevitably occur; it can be understood that the electronic device does not complete unloading the file system within the preset time, which is largely due to the crash of the electronic device. Therefore, in order to prevent the electronic device from crashing and affecting the efficiency, it is necessary to set the maximum time length for executing the uninstall instruction for the electronic device. In this embodiment, the preset time may be 3-4 times the time it takes for the electronic device to normally unload the file system.
Step 306, if the control device receives a failure result of unloading the file system sent by the electronic device, the control device sends an unloading instruction for the file system for the nth time to the electronic device.
Wherein N is a natural number greater than 1 and less than N, and N is the maximum execution time.
In other embodiments of the present invention, after receiving the test completion information sent by the electronic device, the control device sends an uninstalling instruction to control the electronic device to uninstall the file system of the electronic device; it is to be understood that the unload instruction sent at the time of test completion in step 301 is the 1 st unload instruction sent by the control device. If the electronic device fails to unload the file system based on the 1 st unloading instruction, the electronic device can be controlled to unload the file system again after the control device receives the result of the failure of unloading the file system; therefore, a 2 nd unloading instruction can be sent to the electronic device, and the electronic device is controlled to execute 2 nd unloading on the file system; if the electronic equipment still fails to unload after executing the 2 nd unloading instruction, the control equipment sends the 3 rd unloading instruction to the electronic equipment again after receiving the result of failure in unloading the file system; and the like until the control device sends the unloading instruction aiming at the file system for the Nth time.
In the above process, if the electronic device successfully unloads the file system, the control device may directly cut off the power of the electronic device, and exit the unloading process.
It should be noted that, in order to prevent the occurrence of a dead loop in the unloading process, the control device needs to set a maximum unloading number, i.e., a maximum execution number N. That is, after the control device sends the nth uninstall instruction, no uninstall instruction is sent any more regardless of whether the uninstall of the electronic device is successful or not. Wherein, the value of N can be 3-4.
And 307, the electronic device receives the nth unloading instruction aiming at the file system, which is sent by the control device.
Wherein N is a natural number greater than 1 and less than N, and N is the maximum execution time.
In other embodiments of the present invention, after the electronic device completes the test, the file system of the electronic device is unloaded based on receiving an unloading instruction sent by the control device; it can be understood that the uninstall instruction received after the electronic device completes the test in step 302 is the 1 st uninstall instruction.
It should be noted that N sets the maximum unloading number for the control device, and is mainly used to prevent the situation of dead cycle in the unloading process. That is, the electronic device receives the uninstall instruction at most N times. Wherein, the value of N can be 3-4.
And 308, the electronic device uninstalls the file system in the electronic device based on the nth uninstall instruction.
In this embodiment, if the file system in the electronic device fails to be unloaded based on the nth unloading command, the result of the file system failure is sent to the control device, and steps 306 and 307 are executed; and if the file system in the electronic equipment is successfully unloaded based on the nth unloading instruction, which indicates that the unloading of the file system is completed, the control equipment cuts off the power supply of the electronic equipment and exits the unloading process.
Step 309, if the electronic device executes the nth unloading instruction, the file system in the electronic device fails to be unloaded, and a result of the file system unloading failure is sent to the control device.
After the nth unloading instruction is executed, the file system unloading failure in the electronic device may be understood as that the unloading of the file system is still not completed after the electronic device executes the N unloading instructions in total.
And step 310, after sending the nth unloading instruction, the control device receives a failure result of unloading the file system sent by the electronic device, and sends a label representing the file system abnormality to the electronic device.
After the control device sends N times of unloading instructions to the electronic device, the control device still receives a result of failure in unloading the file system, and then may consider that the file system in the electronic device is abnormal, and send a file system abnormal tag to the electronic device, where the file system abnormal tag is used to identify the file system abnormality of the electronic device.
And 311, the electronic device receives a label sent by the control device to represent the file system abnormity.
It should be noted that, for the explanation of the same steps or related concepts in the present embodiment as in the other embodiments, reference may be made to the description in the other embodiments, and details are not described herein again.
