The present disclosure relates to the field of computer applications, and in particular, to a method, an apparatus, a medium, and a device for organizing configuration partitions.
Background
In embedded systems, a single configuration partition is typically divided in its small non-volatile memory for storing configuration files. After the system version is upgraded, part of the configuration file of the previous version may become useless, but still be stored in the configuration partition, and a new configuration file may be stored in the configuration partition, so that more and more data are stored in the configuration partition.

These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present description. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
The configuration file is used for recording configuration information of programs in the system and is an indispensable part of normal operation of the programs. In an embedded system, since the memory space of the embedded system is small, and in order to ensure that the configuration file is not lost during shutdown or restart, the configuration file is generally stored in a configuration partition of a nonvolatile storage device of the embedded system. The nonvolatile memory device of the embedded system is generally a Flash memory card, such as a Compact Flash (CF), and the Flash memory card generally has a small memory space, and a configuration partition in the Flash memory card is also small.
When the version of the embedded system is upgraded, which programs are in the new version and the configuration files corresponding to each program are released, compared with other systems, the configuration files necessary for the system in each version of the embedded system are not changed due to the uninstallation or installation of the programs. After the system version is upgraded, configuration files which are not needed in the configuration partition may be some more, if the configuration files which are not needed in the new version in the configuration partition are not deleted in time, when the system is upgraded again, the configuration partition may have no available storage space to store the new configuration files needed in the upgraded version, so that the system cannot operate normally.
In the prior art, after the system is upgraded, each program in the system is respectively responsible for deleting the configuration files which are not needed by the program. This solution, although deleting some unnecessary configuration files, cannot delete some files in the configuration partition that are not responsible for the program, such as: some programs of the new version are cut off, and the original configuration files of the cut-off programs are not responsible for deleting the corresponding programs; in addition, some non-configuration files in the configuration partition may be wrongly stored, and the files are not responsible for deletion by the corresponding program.
Based on this, in one or more embodiments of the present invention, the scheme in the prior art that each program is responsible for managing the respective configuration files is changed to that in the configuration partition is managed by the system as a whole, and by pre-recording the list of configuration files, the pre-recorded list of configuration files is compared with the files in the configuration partition, so that when there is no redundant storage space in the configuration partition, the system can delete useless files in the configuration partition to release the space in the configuration partition. Therefore, the system can store a new configuration file when the next version is updated, so that the system can normally operate.
The embodiments of the present specification will be described in detail below from two stages, "ready" and "sort".
The preparation stage:
in order to implement the arrangement of the system configuration partitions, when the system version is upgraded, a list of configuration files required by the upgraded version is recorded.
The method for recording the list of the configuration files may be: each program provides the necessary configuration files thereof, and forms a list of the configuration files of the program; and integrating the list of the configuration files of the programs corresponding to all the programs into a total configuration file list. The list of configuration files can be stored in the configuration partition or other storage space, and when the list of configuration files is stored in the configuration partition, in order to prevent the list from being deleted when the configuration partition is arranged, the file of the list needs to be added in the list.
In the list of configuration files, a unique configuration file identification of each required file can be stored; the file may also be found for convenience, in a list of configuration files, the storage directory path of each required file is stored, that is, the list of configuration files includes the storage directory paths of the configuration files in the configuration partition.
Finishing:
based on the pre-recorded list in the preparation stage, the configuration partition can be rearranged when the arrangement needs exist, as shown in fig. 1, fig. 1 is a flowchart of a configuration partition arranging method according to an exemplary embodiment of the present specification, and specifically may include the following steps:
and step 101, judging whether preset configuration partition arrangement conditions are met or not according to the occupation of the storage space of the configuration partition.
The configuration partition is used for storing configuration files. In an embedded system, to prevent the configuration file from being lost when the device is turned off, the configuration partition is a storage space in the nonvolatile memory, such as a certain folder in the CF card.
Step 101 may be: when the specified period is reached, judging whether preset configuration partition arrangement conditions are met or not according to the occupation of the storage space of the configuration partition. The specified period can be selected to be a proper value according to practical situations, for example, the configuration partition can be stored in some non-configuration files frequently, the specified period can be shortened, or the configuration partition is smaller, and the configuration partition can be cleaned frequently. The specified period can be selected as small as possible to realize real-time monitoring of the occupation of the storage space of the configuration partition.
Step 101 may also be: before each system upgrade, judging whether preset arrangement conditions of the configuration partition are met or not according to the storage space occupation of the configuration partition. The arrangement condition of the configuration partition may be whether the occupancy rate of the configuration partition reaches a preset threshold value or whether the size of the space occupied by all files in the configuration partition reaches a preset value. In practice, the preset threshold or preset value may be selected according to practical situations, such as the configuration partition being smaller, and the preset threshold may be set to be smaller, so as to prevent that no space is reserved for storing new configuration files when the system is updated.
In addition, besides judging whether the preset configuration partition arrangement condition is met according to the storage space occupation of the configuration partition, the method can also comprise the following steps: when a user inputs a configuration partition sorting instruction, the configuration partitions are sorted, or after each system upgrade, the configuration partitions are sorted.
Step 102, in the case that the finishing condition is determined to be satisfied, a pre-recorded list is acquired.
In case it is determined that the sort condition is not satisfied, the next execution of step 101 is waited. If step 101 is performed until a specified period is reached, in the event that it is determined that the sort condition is not satisfied, waiting for the arrival of the next specified period.
And step 103, deleting files stored in the current configuration partition and not recorded in the list according to the acquired list.
After step 103 is performed, the next condition triggering the execution of step 101 is waited. If step 101 is performed until a specified period is reached, then the arrival of the next specified period is awaited after completion of step 103.
According to the acquired list, deleting files stored in the current configuration partition and not recorded in the list, wherein the method specifically comprises the following steps: comparing the files stored in the configuration partition with the configuration files in the list, and adding a deletion mark in the files stored in the current configuration partition and not recorded in the list; files stored in the configuration partition that are not recorded in the list are deleted according to the deletion flag.
After each version upgrade of the system, the list of configuration files of the previous version may be deleted. In the case that the list of configuration files is in the configuration partition, after each version upgrade of the system, the list of configuration files of the previous version may not be deleted.
Specifically, as shown in fig. 2, fig. 2 is a flowchart illustrating how to delete a file in a configuration partition sorting method according to an embodiment of the present disclosure, step 103 may include the following steps:
step 1031, obtain all file lists of the configuration partition.
Step 1032, compare the list of all files of the configuration partition with the list of configuration files, add delete markers to files that do not exist in the list of configuration files and exist in the list of all files of the configuration partition.
Step 1033, each file in the configuration partition is processed item by item.
Step 1034, determining whether the file has a delete marker.
If the result of the determination is yes, that is, if the file has a deletion flag, the process goes to step 1035, and if the result of the determination is no, that is, if the file has no deletion flag, the process goes to step 1033.
Step 1035, delete the file.
Step 1036, determining whether to traverse all files of the configuration partition.
If the result of the determination is yes, that is, all the files in the configuration partition have been traversed, the configuration partition is finished, the configuration partition finishing process is finished, and if the result of the determination is no, that is, all the files in the configuration partition have not been traversed, the process goes to 1033.
When the version is updated, the system records the necessary configuration files of the updated version in advance to form a list of the configuration files. When the configuration partition needs to be arranged, the system uniformly deletes files which are not necessary for the version in the configuration partition through the recorded list of the configuration files, and the problem that the configuration files of the program which is cut down in the new version cannot be deleted in the prior art is solved through the system overall management of the configuration partition, so that the probability that the storage space of the configuration partition is fully occupied is reduced, the new configuration files can be written in the configuration partition, and the normal operation of the system after updating is ensured.
For example, as shown in fig. 3, fig. 3 is a flowchart illustrating another configuration partition sorting method according to an embodiment of the present disclosure. In the embedded system, an entry directory of the configuration partition is a/config path, and a list of configuration files is stored in the configuration partition. There are two programs A1 and A2 in the old version, wherein the storage directory path of the configuration file of A1 is/config/A1/1 and/config/A1/2, respectively, the storage directory path of the configuration file of A2 is/config/A2/3, the storage directory path of the list of configuration files of this version is/config/cfg. Before the system version is upgraded, the configuration partition has no unnecessary configuration files and other files, and the files in the list of the configuration partition and the configuration files before the system version is upgraded are the same, wherein the list of the configuration files comprises: the term "config/A1/1,/config/A1/2,/config/A2/3 and/config/cfg.
After the system version is upgraded, A2 is cut off in the new version system, the new version system only has two programs A1 and A3, the storage directory paths of the configuration files required by A1 are/config/A1/1 and/config/A1/4 respectively, and the storage directory paths of the configuration files required by A3 are/config/A3/5. And when the version is upgraded, the list of the configuration files of the new version is replaced by the list of the configuration files of the old version.
After release of the new version, the method comprises the following steps:
in step 301, when the system version is upgraded, a list of configuration files required by the upgraded version is recorded.
When the version is upgraded, recording a list of configuration files required by the upgraded version, and replacing the list of the configuration files with the list of the original configuration files in the configuration partition, wherein the name of the list of the configuration files is cfg. The list of the new version of the configuration file includes the following: the ratio of/config/A1/1,/config/A1/4,/config/A3/5 and/config/cfg. List.
Step 302, after the system version is upgraded, the system is started.
Step 303, it is detected whether a specified period is reached.
After the system version is upgraded, the system is started, and when a specified period is reached, configuration partition arrangement is carried out according to the occupation condition of the configuration partition.
Step 304, judging whether a preset configuration partition arrangement condition is met according to the occupation of the storage space of the configuration partition.
If the determination result is yes, that is, after the preset configuration partition arrangement condition is satisfied, step 305 is executed, and if the determination result is no, step 303 is skipped.
Monitoring whether the occupancy of the configured partition reaches a specified threshold. After the system is upgraded, when the first specified period is reached, the storage directory path of the files in the configuration partition is: the six files enable the configuration partition to reach the preset configuration partition arrangement condition. Then execution continues with step 305.
In step 305, a pre-recorded list is obtained.
In the configuration partition, a list cfg.list of configuration files is obtained by storing directory paths/config/cfg.list.
And 306, deleting files stored in the current configuration partition and not recorded in the list according to the acquired list.
After step 306 is performed, the process jumps to step 303, where the arrival of the next specified period is awaited.
Based on comparing all files in the configuration partition with the list of acquired configuration files, the following unnecessary configuration files are found: a1 has not needed the configuration file/config/A1/2, and cut the original configuration file/config/A2/3 of A2, delete these two files. After deletion, the files in the configuration partition are: the storage space occupancy rate in the configuration partition can not reach the preset configuration partition arrangement condition, and the arrangement of the configuration partition is realized.
In one or more embodiments of the present invention, the scheme in the prior art that each program is responsible for the configuration file management of its own program is changed, files in the configuration partition are managed by the system as a whole, and by pre-recording a list of configuration files, the pre-recorded list of configuration files is compared with the files in the configuration partition, so that when the system has no redundant storage space in the configuration partition, useless files in the configuration partition can be deleted to release the space in the configuration partition. Therefore, the system can store a new configuration file when the next version is updated, so that the system can normally operate.
