Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a first embodiment of a method for manufacturing a memory mirror image according to the present invention. The embodiment of the invention provides a method for manufacturing a memory mirror image, which can be executed by any device for executing the method for manufacturing the memory mirror image, and the device can be realized by software and/or hardware. In this embodiment, the apparatus may be integrated in a terminal device. As shown in fig. 1, the method of this embodiment may include:
step 101, the terminal device judges the state of the terminal device.
In this embodiment, after the terminal device is powered on, it may be determined whether the terminal device is in the memory mirror image making state or the mirror image recovery state. In practical applications, the state of the terminal device can be determined by setting a configuration value in the system, for example: if the configuration value is 0, it can be determined that the terminal device is in the mirror image making state, and if the configuration value is 1, it can be determined that the terminal device is in the mirror image recovery state. It should be noted that the corresponding relationship between the configuration value and the state of the terminal device may be set according to actual needs, which is not limited in the present invention.
Step 102, if the terminal device is in the memory mirror image making state, before the terminal device starts the first application file, performing memory mirror image making processing in a triggered open mode of the database service.
In this embodiment, after the terminal device is started, the boot subsystem is generally started first, and after the boot subsystem is successfully started, the hardware device is initialized, and then the main system is started, and the main system sequentially loads application files, including loading database services, an application manager, and the like. For example: in an embedded operating system, a BootLoader of a boot small system is generally started first to initialize hardware equipment, establish a memory space map and the like, so that the software and hardware environment of the system is brought to a proper state to prepare for loading a main system and other application files. Optionally, the terminal device may be an intelligent terminal device, such as a smart phone, a PAD, and the like.
It should be noted that, in the prior art, after the database service is started, the database file is continuously opened and the handle of the file is held for a long time, so as to perform operations such as querying, inserting, or deleting data. At this time, when a background application file is started, the system, the application state or the setting value may be changed, and since the database file is in an open state, the changed data is stored in the database file, so that dependency is generated between the data of the file system in the memory and the data in the storage medium. To solve this problem, in this embodiment, the operation mode of the database service needs to be the toggle-on mode. In practical application, the database service may be directly started in a default trigger open mode, or the terminal device may detect the entire system when the database service is started, and if it is known that the system is in a state of making a memory mirror image at this time, the working mode of the database service is switched from a long-term open mode to the trigger open mode. It should be noted that, in this embodiment, the working mode of the database service may be a default mode, or may also be a subsequent setting mode, but may also be another mode, as long as the working mode is guaranteed to be the trigger open mode, which is not limited in the present invention. In addition, the storage medium includes a database, a magnetic disk, and other systems or devices that can store data, and the embodiment is not particularly limited in this regard as to the specific form of the storage medium.
For example, taking the Android system as an example for detailed description, after the Android system is started for the first time, the Service Manager (Service Manager) is started by an initialization (Init) process, and the Service Manager sequentially starts other background services including database services (Sqlite), and the like, where the database services may be started directly in a default trigger open mode, or the terminal device may detect the entire system when the database services are started, and if it is known that the system is in a state of making a memory mirror image at this time, the working mode of the database services is switched from a long-term open mode to the trigger open mode.
In this embodiment, after the terminal device finishes scanning all the application files, when the application management service in the terminal device prepares to start the first application file, the memory mirror image manufacturing process is triggered, so as to manufacture the memory mirror image. At this time, because all the application files are not started, and the working mode of the database service is still the trigger open mode, i.e. the database operation is in the loose coupling state, no dependency is generated between the data in the file system in the memory and the data in the storage medium. Meanwhile, all files required by starting are ready at the moment, and the system is at the moment of starting the first application file, so that the moment is the optimal time for manufacturing the memory mirror image, and the manufactured memory mirror image meets the time requirement of quick starting. For example: in the Android system, after an Application Manager (Application Manager) is started by a service Manager, the Application Manager prepares to start an Application file, and before an Application server starts a first Application file, a memory mirror image manufacturing process is triggered to complete the manufacturing of a memory mirror image.
And 103, after the terminal equipment finishes the manufacture of the memory mirror image, starting the first application file.
In this embodiment, after the memory mirror image is manufactured, the terminal device starts a first application file, and starts local application files, including a desktop starter and other preloaded applications, in sequence from the first application file to complete a boot process.
It should be noted that, in the triggered open mode of the database service, after the memory image is made before the first application file is started, when the terminal device is powered on again or restarted again, the memory image can be used for performing field recovery, so as to achieve the purpose of fast startup. The platform services include system background services which exist in the memory image and are started, such as network services, power supply services and the like. For the application files, all the application files are not started when the memory mirror image is manufactured, so that the application files can be loaded by using the latest data value without any modification, and therefore, the memory mirror image manufactured by adopting the method not only avoids the phenomenon that the memory mirror image is required to be manufactured for one time in the latest memory state before the terminal equipment is closed every time in the prior art, but also improves the practicability of the system.
In the method for manufacturing a memory mirror image provided in the embodiment of the present invention, the terminal device determines the state of the terminal device, and if the terminal device is determined to be in the memory mirror image manufacturing state, the terminal device performs memory mirror image manufacturing processing in a triggered open mode of a database service before starting the first application file, and starts the first application file after the memory mirror image is manufactured. Because the memory mirror image is manufactured in the triggering opening mode of the database service and before the first application file is started, the data coupling can be effectively removed, the dependence between the data of the file system in the memory and the data in the storage medium is removed, and the reliability of the system is improved.
Optionally, the triggered opening mode is a processing mode that the database file is opened when the terminal device detects a database operation request, and the database file is closed when the terminal device detects that the database operation request is not detected or detects that the access of the database operation request is finished.
Specifically, when a specific database operation request is detected, the terminal device opens the database file, and when the database operation request is not detected or the access of the database operation request is finished, the database file is immediately closed, and the long-term dependence of the data on the storage medium can be relieved by adopting a triggered opening mode, wherein the database operation request can be, for example, operations such as query, addition, deletion and the like.
Optionally, the terminal device configures a compilation item for the system file to decouple data in the memory from data in the storage medium;
then, the memory mirroring is performed in a triggered open mode of the database service, which includes:
and after the terminal equipment releases the coupling between the data in the memory and the data in the storage medium, performing memory mirroring manufacturing processing in a triggered opening mode of the database service.
Specifically, if there is a phenomenon that some function options are not coupled through the database, the coupling can be released in the compiling stage. In practical application, the terminal device can close some function options for generating data coupling by configuring the compiling item of the system file to remove the compiling options for generating the dependency, so that the coupling between the data in the memory and the data in the storage medium is removed, and the purpose of removing the dependency between the data in the file system in the memory and the data in the storage medium is achieved. For example: for the Android system, a user compiling mode can be adopted for static compiling, and then odex files generated by a dalvik virtual machine for debugging are generated under the condition that the eng mode is not generated during running. And after the generated data coupling is released in the compiling stage, carrying out memory mirror image manufacturing processing in a triggering opening mode of database service.
Optionally, before performing the memory mirroring manufacturing process in the triggered open mode of the database service, the method further includes: the terminal equipment judges whether the working mode of the database service is a long-term open mode or not; and if the working mode of the database service is the long-term opening mode, switching the working mode of the database service from the long-term opening mode to the trigger opening mode.
In the method for manufacturing a memory mirror image provided in the embodiment of the present invention, the terminal device determines the state of the terminal device, and if the terminal device is determined to be in the memory mirror image manufacturing state, the terminal device manufactures the memory mirror image in the triggered open mode of the database service before starting the first application file, and starts the first application file after the memory mirror image is manufactured. Because the memory mirror image is manufactured in the triggering opening mode of the database service and before the first application file is started, the data coupling can be effectively removed, the dependence between the data of the file system in the memory and the data in the storage medium is removed, and the reliability of the system is improved. In addition, when the terminal device configures the compiling item of the system file, the compiling option generating the dependency can be removed to release the coupling of the data, and the consistency of the data in the memory mirror image and the data in the storage medium is ensured.
Fig. 2 is a schematic flow chart of a second method for manufacturing a memory mirror image according to the present invention, and this embodiment describes in detail an embodiment in which a terminal device uses a memory mirror image to realize a fast boot based on the first method for manufacturing a memory mirror image. As shown in fig. 2, the method of this embodiment may include:
step 201, the terminal device determines the state of the terminal device.
Step 201 is similar to step 101 and will not be described herein again.
Step 202, if the terminal device is in the mirror image recovery state, switching the working mode of the database service from the trigger open mode to the long-term open mode.
In this embodiment, when the user powers on the terminal device again and performs field recovery from the memory mirror image, the terminal device performs judgment, and if it is known that the system is in the mirror image recovery state at this time, the working mode of the database service is switched from the trigger open mode to the long-term open mode again, and at this time, the database service is continuously opened and holds a handle of a file for a long time, that is, the performance of the database service is recovered to the normal use state, so as to complete operations such as query, insertion, or deletion of data. For example: in the Android system, after a user powers on a terminal device again, the BootLoader performs mirror image recovery, at this time, the working mode of a database service (Sqlite) is switched to a long-term open mode again from a trigger open mode, and the database service holds db file handles for a long time.
Step 203, the terminal device reads the memory mirror image in the long-term open mode of the database service to start the local application file.
In this embodiment, after the working mode of the database service is switched to the long-term open mode, the terminal device may read the memory image according to the manufactured memory image to complete the boot process of the terminal device, in a specific implementation process, the terminal device only needs to synchronously refresh some data values in the latest state of the platform service, in the specific implementation process, the background service responsible for image recovery sends a notification message to other background services except the background service responsible for memory image recovery, and after receiving the notification message, if it is identified that the data value in the database is recovered from the memory image according to the notification message, the other background services only need to re-read the data in the database and apply the data value in the latest state. The platform services include system background services which exist in the memory image and are started, such as network services, power supply services and the like. For the application files, all the application files are not started when the memory mirror image is manufactured, so that the application files can be loaded by using the latest data value without any modification. In addition, because the data in the memory mirror image and the data in the storage medium are in a loose coupling state, the system can not be crashed in the process of quick startup. Therefore, the terminal device can smoothly start the desktop application and other services defined as preloaded, for example, the desktop Launcher and other preloaded applications.
In the method for manufacturing a memory mirror image provided in the embodiment of the present invention, the terminal device determines the state of the terminal device, and if the terminal device is determined to be in the memory mirror image manufacturing state, the terminal device manufactures the memory mirror image in the triggered open mode of the database service before starting the first application file, and starts the first application file after the memory mirror image is manufactured. Because the memory mirror image is manufactured in the triggering opening mode of the database service and before the first application file is started, the data coupling can be effectively removed, the dependence between the data of the file system in the memory and the data in the storage medium is removed, and the reliability of the system is improved. In addition, when the terminal equipment is in the mirror image recovery state, the working mode of the database service is switched to a long-term opening mode, and the memory mirror image is read in the working mode, so that the aim of quickly starting the terminal equipment by using the memory mirror image is fulfilled.
Fig. 3 is a flowchart illustrating a third embodiment of a method for manufacturing a memory mirror image according to the present invention. The embodiment of the invention provides a method for manufacturing a memory mirror image, which can be executed by any device for executing the method for manufacturing the memory mirror image, and the device can be realized by software and/or hardware. In this embodiment, the apparatus may be integrated in a terminal device. As shown in fig. 3, the method of this embodiment may include:
step 301, the terminal device determines the state of the terminal device.
In this embodiment, after the terminal device is powered on, it may be determined whether the terminal device is in the memory mirror image making state or the mirror image recovery state. In practical applications, the state of the terminal device can be determined by setting a configuration value in the system, for example: if the configuration value is 0, it can be determined that the terminal device is in the mirror image making state, and if the configuration value is 1, it can be determined that the terminal device is in the mirror image recovery state. It should be noted that the corresponding relationship between the configuration value and the state of the terminal device may be set according to actual needs, which is not limited in the present invention.
Step 302, if the terminal device is in the memory mirror image making state, the terminal device performs memory mirror image making processing before starting the first application file and before starting the database service.
In the prior art, after a database service is started, a database file is continuously opened and a handle of the file is held for a long time to perform operations such as query, insertion or deletion of data, at this time, when a background application file is started, a system, an application state or a setting value may be changed, and since the database file is in an open state, the changed data is stored in the database file, so that dependency is generated between data of a file system in a memory and data in a storage medium. In order to solve this problem, in this embodiment, if the terminal device is in the memory mirror image making state, after the terminal device finishes scanning all the application files, before starting the first application file and before starting the database service, a memory mirror image making process is triggered, so as to make a memory mirror image. At this time, since all the application files are not started and the database service is not started, there is no dependency between the data in the file system in the memory and the data in the storage medium.
Step 303, after the terminal device completes the manufacture of the memory mirror image, starting the first application file.
In this embodiment, after the memory mirror image is manufactured, the terminal device starts a first application file, and starts local application files, including a desktop starter and other preloaded applications, in sequence from the first application file to complete a boot process.
In the method for manufacturing a memory mirror image provided in the embodiment of the present invention, the terminal device determines the state of the terminal device, and if the terminal device is determined to be in the memory mirror image manufacturing state, the terminal device performs memory mirror image manufacturing processing before starting the first application file and before starting the database service, and starts the first application file after the memory mirror image is manufactured. Because the memory mirror image is manufactured before the first application file is started and before the database service is started, the data coupling can be effectively released, the dependence between the data of the file system in the memory and the data in the storage medium is released, and the reliability of the system is improved.
Fig. 4 is a schematic structural diagram of a first apparatus for manufacturing a memory mirror image according to an embodiment of the present invention. As shown in fig. 4, the apparatus 400 for manufacturing a memory image according to an embodiment of the present invention includes a determining module 401, a processing module 402, and a starting module 403.
The judging module 401 is configured to judge the state of the terminal device; the processing module 402 is configured to perform memory mirroring processing in a triggered open mode of a database service before starting the first application file when the determining module 401 determines that the terminal device is in the memory mirroring processing state; the starting module 403 is configured to start the first application file after the memory image is manufactured.
