[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a file administration method. Specifically, the file supervision method provided by the embodiment of the present invention includes, for example, the steps of:
s11: determining a file to be supervised;
s12: acquiring a backup threshold value of the file to be supervised;
s13: setting a supervision alarm clock;
s14: and calling a designated alarm clock processing function to process the file to be supervised based on the supervision alarm clock trigger, wherein the processing operation comprises the steps of backing up the file to be supervised when the file to be supervised meets the backup threshold value to obtain a backup file, and clearing the backed-up content of the file to be supervised so that the file to be supervised caches new content.
Therefore, the alarm clock processing function is called according to the backup threshold value through the supervision alarm clock to backup the file to be supervised and clear the content, so that the size of the file to be supervised is effectively controlled, the problem that the performance and efficiency of the system are influenced by file transmission or file operation due to the fact that a single file is too large is avoided, and the working performance of the embedded equipment is improved.
Specifically, as shown in fig. 2, when the backup threshold is the file size threshold of the file to be supervised, step S13, for example, further includes the steps of:
periodically acquiring the file size of the file to be supervised based on the supervision alarm clock;
and calling the designated alarm clock processing function to judge whether the file size of the file to be supervised is larger than the file size threshold of the file to be supervised.
Further, as shown in fig. 2, the document supervision method may further include the steps of:
s15: and compressing the backup file to obtain a backup compressed file.
As shown in fig. 2, the document supervision method may further include the steps of:
s16: and deleting the backup compressed file with the earliest backup time in response to the number of the backup compressed files meeting a preset value.
In order to facilitate understanding of the present invention, the steps of the document supervision method of the present embodiment will be described in detail below with reference to fig. 3 and 4.
The file supervision method provided by the embodiment of the invention is suitable for file supervision of embedded equipment such as multimedia broadcast control equipment and the like, and can avoid the influence of file transmission or file operation on the performance and efficiency of a system due to too large single file. Typically, as shown in fig. 3, the multimedia playback device includes, for example, an embedded processor and a non-volatile memory connected to the embedded processor. The embedded processor is, for example, an ARM core-based processor, on which an embedded operating system, such as an Android system based on Linux, is installed, and is mainly used for managing and controlling the multimedia broadcast control device. Various application software such as monitoring software, service software such as media playing control software and the like can be installed on the embedded operating system. Various application software generally generates files in the running process to cache corresponding data and parameters for later troubleshooting, performance analysis and the like. The nonvolatile memory is, for example, an EMMC (Embedded multimedia Card), which can be used to store the aforementioned various files or other spare data files, such as log files. Of course, the non-volatile memory may also be other memories such as FLASH (FLASH memory). In addition, the multimedia broadcast control device can also comprise a programmable logic device. The programmable logic device is connected with the embedded processor. The Programmable logic device is, for example, an FPGA (Field-Programmable Gate Array), and is used for receiving media input, processing the media, and finally outputting the processed media for display. The following describes in detail a specific implementation process of the file supervision method provided by the embodiment of the present invention.
First, as shown in FIG. 4, the embedded processor determines the file to be curated. The file to be supervised here can be, for example, a log file generated by application software installed on the Android operating system, such as multimedia broadcast control software. The file to be supervised can be one file to be supervised of one application software or a plurality of files to be supervised of a plurality of application software. The embedded processor may obtain and determine the file to be supervised by responding to the user operation, or may read the name of the file to be supervised from, for example, a supervision configuration file, so as to determine the file to be supervised, which is not limited herein. Of course, the supervision configuration file may include file names of files to be supervised corresponding to a plurality of application software.
Then, the embedded processor obtains the backup threshold value of the file to be supervised. The backup threshold may be used, for example, to control the size of the files to be curated. The backup threshold is, for example, a file size threshold, or a file cache time threshold to be supervised. When the backup threshold is the file size threshold, the embedded processor is indicated to process the file to be supervised by controlling the size of the file to be supervised. For example, the file size threshold is 100MB, i.e., the size of the file to be policed is not greater than 100 MB. And when the backup threshold is the cache time threshold of the file to be supervised, the embedded processor is indicated to process the file to be supervised by controlling the cache time of the file to be supervised. For example, the caching time threshold of the file to be supervised is 24 hours, that is, the caching time of the file to be supervised does not exceed 24 hours. It is worth mentioning here that the embedded processor obtains the backup threshold of the file to be supervised in response to the user operation. The backup threshold may also be stored in a monitoring configuration file of the file to be monitored, and the embedded processor is obtained by reading the backup threshold corresponding to the file to be monitored in the monitoring configuration file, which is not limited in the present invention.
Secondly, the embedded processor sets up a supervision alarm clock. Specifically, the embedded processor sets a monitoring period of the supervision alarm clock. The monitoring period here may be, for example, 1 minute, 1 hour, 24 hours, or the like. The monitoring period can be set by a user according to actual conditions. When the backup threshold is the caching time threshold of the file to be supervised, the monitoring period of the supervision alarm clock can be equal to the caching time threshold of the file to be supervised.
Then, as shown in fig. 4, the embedded processor calls a designated alarm clock processing function based on the supervision alarm clock trigger to perform a processing operation on the file to be supervised. Specifically, the embedded processor periodically triggers and calls a designated alarm clock processing function to monitor the state of the file to be supervised according to the monitoring period of the supervision alarm clock. And when the file to be supervised meets the backup threshold value, backing up the file to be supervised to obtain a backup file, and removing the backed-up content of the file to be supervised so that the file to be supervised caches new content. The clearing of the backed-up content of the file to be supervised may be partial clearing or complete clearing, and the present invention is not limited thereto. More specifically, when the backup threshold is the cache time threshold of the file to be supervised, it indicates that the embedded processor performs the processing operation on the file to be supervised by monitoring the cache time of the file to be supervised, and the monitoring period of the supervision alarm clock is equal to the cache time threshold of the file to be supervised, for example, 24 hours. Therefore, the embedded processor starts the supervision alarm clock once every 24 hours and triggers and calls a specified alarm clock processing function corresponding to the supervision mode corresponding to the cache time threshold of the file to be supervised, such as the file cache time supervision mode, to perform processing operation, for example, when the cache time of the file to be supervised reaches the cache time threshold of the file to be supervised, such as 24 hours, the embedded processor triggers and calls the alarm clock processing function to backup the file to be supervised to obtain a backup file, and removes the backed-up content of the file to be supervised, so that the file to be supervised caches new content. When the backup threshold is the file size threshold, for example, 100MB, it indicates that the embedded processor performs processing operation on the file to be supervised by monitoring the file size of the file to be supervised, and the monitoring period of the supervision alarm clock may be equal to 1 minute, for example. Therefore, the embedded processor starts the supervision alarm clock once every 1 minute and triggers and calls a specified alarm clock processing function corresponding to a supervision mode corresponding to a file size threshold value, for example, a file size supervision mode, to perform processing operation, for example, the method includes periodically obtaining the file size of a file to be supervised based on a management alarm clock, calling the specified alarm clock processing function to judge whether the file size of the file to be supervised is larger than the file size threshold value of the file to be supervised, when the size of the file to be supervised is larger than the file size threshold value, for example, 100MB, the embedded processor triggers and calls the alarm clock processing function to backup the file to be supervised to obtain a backup file, and removes the backed-up content of the file to be supervised, so that the file to be supervised caches new. It should be noted here that clearing the backed-up content of the file to be supervised can be understood as clearing all the backed-up content of the file to be supervised, and can also be understood as clearing part of the backed-up content of the file to be supervised. If the monitored size of the file to be monitored is not larger than the file size threshold, stopping monitoring, entering a sleep state, and starting the alarm clock again for monitoring after the next monitoring period, so that too much CPU resource is not consumed. It should be noted here that the supervision mode may also be stored in the supervision configuration file as a parameter, and the embedded processor reads the parameter value from the supervision configuration file to determine a designated alarm clock processing function corresponding to the supervision mode, so as to perform a corresponding processing operation.
Log, when the supervision mode is a file size supervision mode, the backup threshold is a file size threshold, and the file size threshold is 100 MB. The embedded processor determines a file to be supervised, acquires a backup threshold value and sets the monitoring period of the supervision alarm clock to be 1 minute. The embedded processor starts a supervision alarm clock every 1 minute, calls an alarm clock processing function based on the triggering of the supervision alarm clock to perform processing operation on the example.log, for example, the size of the example.log is acquired, whether the size of the example.log is larger than a file size threshold is judged, when the monitored result shows that the size of the example.log is larger than the set file size threshold of 100MB, the embedded processor copies the example.log through the alarm clock processing function to obtain a copy of the example.log.1, namely a backup file, and then clears the backed-up content in the example.log, so that new content can be continuously cached into the example.log file. Therefore, the size of the file to be supervised can be controlled to be about 100MB, so that the influence of file transmission or file operation on the performance and efficiency of the system due to the overlarge file to be supervised is avoided, and the running performance and stability of the system are improved.
Log, and when the supervision mode is a file cache time supervision mode, the cache time threshold of the file to be supervised is 24 hours, so that the monitoring period of the supervision alarm clock is also 24 hours. The embedded processor copies example log every 24 hours to get a copy of example log.1, i.e. a backup file, and then clears, e.g. empties, the backed up content in example log, so that it can continue to cache new content into example log files. Therefore, the files to be monitored can be backed up and cleared regularly, and the size of a single file to be monitored is ensured not to be too large, so that the influence on the performance and efficiency of the system caused by file transmission or file operation due to overlarge files is avoided, and the running performance and stability of the system are improved.
Furthermore, after the files to be monitored are backed up and emptied, the embedded processor can also compress the backup files to obtain compressed backup files and delete the backup files. Log.1 is a backup file, for example. The embedded processor compresses example.log.1 to obtain an example.log.1.gz compressed package, namely a compressed backup file, and then deletes the backup file, namely an example.log.1 file. Therefore, the compressed backup file example.log.1 occupies a smaller disk space than the backup file example.log.1. gz. Typically, compressed backup files are about 15-20 times smaller than uncompressed backup files. Therefore, the occupation of the backup files on the disk space can be further reduced, the occurrence of system or service software abnormal operation and other faults caused by too much occupied disk space of the files is reduced, and the stability and the reliability are further improved.
Furthermore, the embedded processor can also control the occupied space of the disk by setting a preset value of the total number of files, namely the total number of files which can be stored on the disk. The total number of files herein may be, for example, the total number of files to be supervised and compressed backup files, may also refer to the total number of compressed backup files, and may also be the total number of files to be supervised, backup files and compressed backup files, which is not limited in this disclosure. The embedded processor monitors the number of files stored on the disk. When the number of files meets a preset value, for example, the number of files reaches the preset value, the embedded processor deletes the file with the oldest generation time, namely the file with the oldest backup time. Therefore, the number of the files on the disk can be continuously monitored, abnormal operation of a system or application software caused by disk explosion due to too much disk space occupied by the files is further avoided, and the stability and the reliability are further improved.
In summary, according to the embodiment of the present invention, the alarm clock processing function is called by the supervision alarm clock according to the backup threshold value to backup and empty the content of the file to be supervised, so that the size of the file to be supervised is effectively controlled, the influence on the performance and efficiency of the system due to file transmission or file operation caused by too large single file is avoided, and the working performance of the embedded device is improved. In addition, the backup compressed file is obtained by compressing the backup file, and the backup file is deleted, so that the backup file occupies a larger disk space, the occurrence of faults such as abnormal operation of system or service software and the like caused by too much disk space occupied by the file is further reduced, and the stability and the reliability are further improved. Moreover, by monitoring the number of the files on the disk and deleting the file with the earliest backup time when the number exceeds a preset value, the abnormal operation of a system or application software caused by the disk fullness due to too much disk space occupied by the file is further avoided, and the stability and the reliability are further improved. In addition, by monitoring the files to be monitored, the storage space can be saved, the cost of a storage chip is reduced, the files to be monitored of the application software to be monitored can be randomly specified, the controllability of the system on the whole log cache is improved, system-level debugging logs can be monitored, and the monitoring device is greatly helped. Therefore, the unified management of all the files to be supervised of the system can be realized, the files can be managed according to time and the size of the files to be supervised, and the problems of disorder and nonuniform management of the files to be supervised in the system are solved.
