Description

 Data partition storage space management method and device

Technical field

The present invention relates to the field of data storage technologies, and in particular, to a storage space management method and apparatus for data partitioning.

Background technique

The partition of the android device includes the system partition and the data partition. Data partitions are used to store various types of user data and applications that users can read and write. Erasing this partition is equivalent to restoring the factory settings, which is the state when the android system was first started, or the state after the last installation of the official or third-party ROM. It is generally necessary to set a capacity limit for data partitions, and to prevent hackers from illegally writing data to the data partition, or to prevent malicious files from being maliciously destroyed by creating illegal files.

Because most of the user-operated data of the running android system will be saved in the data partition by default, such as the newly downloaded application data, the cache data of the application running, the image video downloaded by the application, etc., so that the data partition is easily filled up. Android system is abnormal. Each application can have measures to detect the available space in the data partition, but in most cases the application only detects the available space of the data partition before the download task, and does not detect intermittently during the download process. When multiple applications download data at the same time, they can detect the available data space before downloading, but there may be a problem that the data partition is "filled up" when multiple applications are downloaded at the same time.

Android system generally uses DSMS (Device Storage Monitor Service) to monitor the status of the internal storage space of the system. If the remaining storage space of the device is less than a certain threshold (the default is 10% of the storage space, this value can be set), the user will be sent a warning of insufficient remaining space. The user releases some space. Let's take a data partition as an example to illustrate this process:

The DSMS detects the remaining space of the data partition every 1 minute. When the available space of the data partition is less than the threshold (between 10% and 500M of the total partition size), the cache will be automatically cleared; the cache is cleared and then calculated. The free space of the data partition, if it is still less than the threshold, will send a warning notice to the notification bar and send an ACTION_DEVICE_STORAGE_LOW broadcast. The user can open the application manager and manually clear the application data to increase the available space of the data partition. The application itself can also listen to the ACTION_DEVICE_STORAGE_LOW broadcast to do some special processing. For example, the email application will stop when it receives the broadcast. The current operation of sending and receiving mail. When the DSMS service detects that the space is full, it will send a broadcast with full space; if the remaining space is detected to be greater than the threshold, and the previous low space or insufficient space is issued, the above prompt will be canceled and the ACTION_DEVICE_STORAGE_OK broadcast will be sent. If the amount of data downloaded during this minute is very large, it is possible that the full-filled broadcast has not yet been sent, and the data partition is full, causing the application to fail to function properly.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a storage space management method for data partitioning. Referring to FIG. 1, a flowchart of a first embodiment of a storage space management method for a data partition of the present invention is shown.

In this embodiment, the storage space management method of the data partition includes:

Step S10, detecting a remaining storage space of the data partition according to the first preset frequency;

In step S20, when it is detected that the remaining storage space is smaller than the first preset threshold, the remaining storage space in the data partition is detected according to the second preset frequency, where the second preset frequency is greater than the first preset frequency. ;

The method provided in this embodiment is applicable to a mobile terminal such as a mobile phone or a tablet computer with an intelligent operating system. The following is an example of a mobile phone with an android operating system installed. The various steps in the method proposed by this embodiment can be implemented by different functional modules.

There are a variety of applications installed on the mobile phone. During the running process, there will be data partitioning, that is, the storage space of the mobile phone, and writing data, such as downloading pictures, downloading files, and the like.

The detection of the size of the remaining storage space of the data partition is performed periodically. For example, the detection may be performed according to the first preset frequency. When it is detected that the remaining storage space is less than the first preset threshold, the current remaining storage space is considered to be insufficient. The module for detecting the amount of remaining storage space can send an ACTION_DEVICE_STORAGE_LOW broadcast to inform other function modules that the current storage space is insufficient. In order to prevent the application from running incorrectly during the process of writing data, the remaining operation is accelerated. The detection of the storage space, that is, detecting the remaining storage space of the data partition according to the second preset frequency.

In general, the size of the first preset threshold may be set according to the total size of the data partition of the mobile phone, for example, may be set to be between 10% and 500M of the total size of the data partition; the first preset frequency may be every 40 Detected once every second to 1 minute, the second preset frequency is less than the first preset frequency, for example, it can be detected every 10-30 seconds.

Step S30, when it is detected that the remaining storage space is less than the second preset threshold, displaying warning information that the storage space is full and an application data management interface, so that the user performs data clearing based on the application data management interface to release the storage space. The second preset threshold is smaller than the first preset threshold.

When detecting that the remaining storage space is less than the second preset threshold according to the second preset frequency, displaying warning information that the storage space is full, and an application data management interface, the user may clear the application data based on the data management interface of the application, to The storage space is released. In the prior art, the warning information is sent in the notification bar, and the user does not easily notice that the method proposed in this embodiment can make the user intuitively see the warning that the space is full, and the user can intuitively see the warning that the space is full. Quickly clean up application data, without requiring the user to manually open the data management application and clean up the data in a timely manner.

At this time, the module for detecting the amount of remaining storage space sends an ACTION_DEVICE_STORAGE_NOT_FULL broadcast to inform other function modules that the current storage space is full.

In this embodiment, the second preset threshold is smaller than the first preset threshold, and optionally, the second preset threshold is 1/4 of the first preset threshold.

Further, as an implementation manner, when the remaining storage space is insufficient, the warning information indicating that the storage space is insufficient and the application data management interface are issued. At this time, although the remaining storage space still has a margin, as the write data proceeds, the remaining The amount of information will be smaller and smaller, in order to enable the user to clean the application data early to release the storage space, and when the remaining storage space is detected to be less than the first preset threshold, the warning information indicating insufficient storage space and the application data management interface are displayed. For the user to perform data cleaning based on the application data management interface to release the storage space.

The storage space management method for the data partition proposed in this embodiment detects the remaining storage space of the data partition according to a certain frequency in the process of writing data to the data partition, and when detecting that the remaining storage space is smaller than the first preset threshold, Increase the frequency of the remaining storage space in the detection data partition, optimize the frequency of detecting the remaining storage space, and find out that the remaining storage space of the partition is insufficient. When it is detected that the remaining storage space is less than the second preset threshold, the data partition is indicated at this time. The remaining storage space is not much. If a certain amount of data is written, the data partition may be filled, which may affect the normal operation of the application. Therefore, when it is detected that the remaining storage space is less than the second preset threshold, That is, a warning message is issued, and an application data management interface is displayed at the same time, so that the user can perform data clearing based on the application data management interface to release the storage space, which can prevent the storage space from being quickly insufficient to full and causing the application to fail to operate normally.

A second embodiment of the storage space management method of the data partition of the present invention is proposed based on the first embodiment. Referring to FIG. 2, in the embodiment, after the step S10, the storage space management method of the data partition further includes:

Step S40, when it is detected that the remaining storage space is less than the second preset threshold, setting a value of the preset attribute to mark the remaining storage space of the data partition to be smaller than a second preset threshold;

Step S50, before each write to the write function to write data to the data partition, determine, according to the value of the preset attribute, whether the remaining storage space of the data partition is smaller than a second preset threshold;

Step S60: Send the prompt information of the read/write abnormality to the application layer if the remaining storage space is smaller than the second preset threshold.

Step S70: If the remaining storage space is greater than or equal to the second preset threshold, the write function is called to write data to the data partition.

The method in this embodiment provides a preset attribute and a module for setting a value of the preset attribute. Optionally, the preset attribute is sys.device.storage.low, and the default value is false, when detecting When the remaining storage space is less than the second preset threshold, set the value of sys.device.storage.low to true, that is, the current storage space is insufficient.

Further, after the user clears the application data, the storage space is released. Therefore, when it is detected that the remaining storage space is greater than or equal to a second preset threshold, setting a value of the preset attribute to use the data. The amount of storage of the partition is marked as greater than or equal to the second predetermined threshold. That is, when it is detected that the remaining storage space is greater than or equal to the second preset threshold, the value of sys.device.storage.low is set to false, that is, the current remaining storage space is sufficient.

Because most Android applications write files through Java, such as FileOutputStream, OutputStreamWriter, and FileWriter. The io class is implemented, and these classes will eventually call the write function of IoBridge.java. For the data read/write module used to write data to the data partition, write the data to the partition every time the function Posix.write is called. Before the time, the value of the preset attribute is determined, and the remaining storage space of the current data partition is determined to be smaller than the second preset threshold according to the value of the preset attribute. If the value of sys.device.storage.low is true, a read/write exception is sent to the application layer. If the value of sys.device.storage.low is false, the function Posix.write is called to continue the write operation. The module for setting the value of the preset attribute is shared to the shared memory after setting the attribute value. Therefore, for the data read/write module, the method for obtaining the preset attribute value is used to determine whether the available space of the data partition is smaller than the second. The preset threshold greatly improves efficiency compared to directly calculating the available space of the data partition.

A third embodiment of the storage space management method of the data partition of the present invention is proposed based on the first embodiment or the second embodiment. In this embodiment, when it is detected that the remaining storage space is less than the second preset threshold, it is determined whether the system is in the completed startup state; if the system is currently in the completed startup state, performing a setting of the preset attribute value to The remaining storage space of the data partition is marked as being less than a second predetermined threshold.

In this embodiment, the value of the system attribute sys.boot_completed is set to indicate whether the system has been started. If the system is confirmed to be in the running state after the startup is completed, the preset attribute sys.device.storage.low is set to true, and vice versa. Set to false.

Since the mobile phone may restart the system due to the setting of the application during the process of writing data, and setting the value of the preset attribute needs to be set when the system is started up and running normally, therefore, in this case In the implementation, before setting the system property, whether the value of sys.device.storage.low is set to true or the value of sys.device.storage.low is set to false, the system property sys.boot_completed will be obtained before then. The value of the value to determine whether the system is currently in the running state after the completion of the startup. After confirming that the system is running after the startup is completed, set the default attribute sys.device.storage.low.

The invention also proposes a storage space management device for data partitioning.

Referring to FIG. 3, it is a schematic diagram of functional modules of a first embodiment of a storage space management apparatus for data partitioning according to the present invention.

In this embodiment, the storage space management device of the data partition includes:

The partition monitoring module 10 is configured to detect a remaining storage space of the data partition according to the first preset frequency;

And detecting, when the remaining storage space is less than the first preset threshold, detecting a remaining storage space in the data partition according to the second preset frequency, wherein the second preset frequency is greater than the first preset frequency;

The device proposed in this embodiment may be a mobile terminal such as a mobile phone or a tablet computer with a smart operating system. The following is an example of a mobile phone with an android operating system installed. The various functional modules included in the device proposed by this embodiment are used to perform different functions.

There are a variety of applications installed on the mobile phone. During the running process, there will be data partitioning, that is, the storage space of the mobile phone, and writing data, such as downloading pictures, downloading files, and the like. The partition monitoring module 10 periodically detects the size of the remaining storage space of the data partition. For example, the detection may be performed according to the first preset frequency. When it is detected that the remaining storage space is less than the first preset threshold, the current remaining storage space is considered. At this time, the partition monitoring module 10 can send an ACTION_DEVICE_STORAGE_LOW broadcast to inform other functional modules that the current storage space is insufficient. In order to prevent the application from running wrong during the process of writing data, the remaining storage is accelerated. The detection of the space, that is, detecting the remaining storage space of the data partition according to the second preset frequency.

In general, the size of the first preset threshold may be set according to the total size of the data partition of the mobile phone, for example, may be set to be between 10% and 500M of the total size of the data partition; the first preset frequency may be every 40 Detected once every second to 1 minute, the second preset frequency is less than the first preset frequency, for example, it can be detected every 10-30 seconds.

The information prompting module 20 is configured to display, when the remaining storage space is less than the second preset threshold, the warning information that the storage space is full, wherein the second preset threshold is smaller than the first preset threshold;

The interface display module 30 is configured to display an application data management interface for the user to perform data clearing based on the application data management interface to release the storage space when detecting that the remaining storage space is less than a second preset threshold.

When the remaining storage space is detected to be less than the second preset threshold according to the second preset frequency, the information prompting module 20 displays the warning information that the storage space is full, and the interface display module 30 displays the application data management interface, and the user can use the data based on the application. The management interface clears the application data to release the storage space. In the prior art, the warning information is sent in the notification bar, and the user does not easily notice that the method proposed in this embodiment can make the user intuitively view relative to the existing notification mode. The warning that the space is full, and the application data is quickly cleaned up, the user does not need to manually open the data management application, and the data is cleaned in time.

At this time, the partition monitoring module 10 sends an ACTION_DEVICE_STORAGE_NOT_FULL broadcast to inform other functional modules that the current storage space is full.

In this embodiment, the second preset threshold is smaller than the first preset threshold, and optionally, the second preset threshold is 1/4 of the first preset threshold.

Further, as an implementation manner, the information prompting module 20 issues a warning message that the storage space is insufficient when the remaining storage space is insufficient, and the interface display module 30 displays the application data management interface. At this time, although the remaining storage space still has a margin, However, as the write data proceeds, the margin will become smaller and smaller, in order to enable the user to clean the application data early to release the storage space, and display the storage space when detecting that the remaining storage space is less than the first preset threshold. Insufficient warning information and an application data management interface for the user to perform data cleaning based on the application data management interface to release storage space.

The storage space management device of the data partition proposed in this embodiment detects the remaining storage space of the data partition according to a certain frequency in the process of writing data to the data partition, and when detecting that the remaining storage space is smaller than the first preset threshold, Increase the frequency of the remaining storage space in the detection data partition, optimize the frequency of detecting the remaining storage space, and find out that the remaining storage space of the partition is insufficient. When it is detected that the remaining storage space is less than the second preset threshold, the data partition is indicated at this time. The remaining storage space is not much. If a certain amount of data is written, the data partition may be filled, which may affect the normal operation of the application. Therefore, when it is detected that the remaining storage space is less than the second preset threshold, That is, a warning message is issued, and an application data management interface is displayed at the same time, so that the user can perform data clearing based on the application data management interface to release the storage space, which can prevent the storage space from being quickly insufficient to full and causing the application to fail to operate normally.

A second embodiment of the storage space management apparatus of the data partition of the present invention is proposed based on the first embodiment. Referring to FIG. 4, in the embodiment, the storage space management device of the data partition further includes:

The system attribute module 40 is configured to: when detecting that the remaining storage space is less than a second preset threshold, set a value of the preset attribute to mark the remaining storage space of the data partition to be smaller than a second preset threshold;

The data reading and writing module 50 is configured to determine, according to the value of the preset attribute, whether the remaining storage space of the data partition is smaller than a second preset threshold, before each write to the data function is written to the data partition;

The data reading and writing module 50 is further configured to: if the remaining storage space is less than the second preset threshold, send the prompt information of the read/write abnormality to the application layer; and if the remaining storage space is greater than or equal to the second preset threshold, A write function is called to write data to the data partition.

This embodiment provides a preset attribute. Optionally, the preset attribute is sys.device.storage.low, and the default value is false. When the remaining storage space is detected to be less than the second preset threshold, the sys.device is used. The value of .storage.low is set to true, that is, the current storage space is insufficient.

Further, after the user clears the application data, the storage space is released. Therefore, when detecting that the remaining storage space is greater than or equal to a second preset threshold, the system attribute module 40 sets the value of the preset attribute to The storage amount of the data partition is marked as being greater than or equal to the second predetermined threshold. That is, when it is detected that the remaining storage space is greater than or equal to the second preset threshold, the system attribute module 40 sets the value of sys.device.storage.low to false, that is, the current remaining storage space is sufficient.

Because most Android applications write files through Java, such as FileOutputStream, OutputStreamWriter, and FileWriter. The io class is implemented, and these classes will eventually call the write function of IoBridge.java. The data read/write module 50 adds the value judgment of the preset attribute before each time the function Posix.write is called to write data to the partition. Determining, according to the value of the preset attribute, whether the remaining storage space of the current data partition is less than a second preset threshold. If the value of sys.device.storage.low is true, the data read/write module 50 sends a read/write exception to the application layer. If the value of sys.device.storage.low is false, the data read/write module 50 calls the function Posix. Write continues to perform write operations. After the attribute value is set, the system attribute module 40 shares the shared memory. Therefore, for the data read/write module 50, the method for obtaining the preset attribute value determines whether the available space of the data partition is smaller than the second preset threshold than the direct calculation. The usable space of the data partition greatly improves efficiency.

A third embodiment of the storage space management apparatus of the data partition of the present invention is proposed based on the first embodiment or the second embodiment. Referring to FIG. 5, in the embodiment, the storage space management device of the data partition further includes:

The state determining module 60 is configured to determine, when the remaining storage space is less than the second preset threshold, whether the system is currently in the state of completing the startup;

The system attribute module 40 is further configured to: if the system is currently in the state of completing the startup, set a value of the preset attribute to mark the remaining storage space of the data partition to be smaller than a second preset threshold.

In this embodiment, the system attribute module 40 sets the preset attribute sys.device.storage.low by setting the value of the system attribute sys.boot_completed to indicate whether the system has been started. True, otherwise it is set to false.

Since the mobile phone may restart the system due to the setting of the application during the process of writing data, and setting the value of the preset attribute needs to be set when the system is started up and running normally, therefore, in this case In the implementation, before setting the system property, whether the value of sys.device.storage.low is set to true or the value of sys.device.storage.low is set to false, the state judging module 60 will acquire the system before this. The value of the attribute sys.boot_completed to determine whether the system is currently in the running state after the startup is completed. After confirming that the system is in the running state after the startup is completed, the system property module 40 sets the preset attribute sys.device.storage.low.

The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformations made by the description of the present invention and the drawings are directly or indirectly applied to other related technical fields. The same is included in the scope of patent protection of the present invention.
