The embodiment of the invention provides a method and a device for upgrading a system, which solve the problem of upgrading the system by a non-writable partition.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. 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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1, a method for upgrading a system according to an embodiment of the present invention is described in detail below, where the method for upgrading a system according to the embodiment of the present invention includes:
101. receiving a system upgrading instruction;
in this embodiment, the system upgrade apparatus first receives a system upgrade instruction, where the system upgrade instruction may be triggered or may be automatically triggered when the terminal device detects that the system needs to be updated, and the system upgrade instruction is used to indicate that the terminal device may currently perform system upgrade.
102. Determining whether each partition of the current system is writable;
in this embodiment, the system upgrade apparatus determines whether each partition in the current system is writable, where a partition may refer to a partition in hardware or a partition in code logic. When a developer of an operating system develops the system, for some parts which do not need to be modified frequently or functions with high security, the content of the parts is written into a partition and is set as unwritable, so that a user cannot modify the content of the parts.
103. Modifying the permission of the non-writable partition in the current system into writable partition, and upgrading the writable partition in the current system according to a system upgrading instruction;
in this embodiment, as described in step 102 above, if it is determined that the non-writable partition exists in the current system, the permission corresponding to the non-writable partition in the current system needs to be set as writable. Wherein, the right means that a certain user has a specific system resource usage right. Typically, a system administrator, or a network administrator in a network, may assign different permissions to users for the use of a particular resource, and the system software automatically enforces those permissions.
The device for upgrading the system can upgrade the writable partition in the current system according to the system upgrading instruction while modifying the permission of the non-writable partition in the current system into writable partition. The upgrading process is that the writable partition is upgraded by adopting the upgrading compression packet, and the upgrading of the non-writable partition cannot be finished at this time because the permission of the non-writable partition is only modified to be writable at this time but is not effective yet.
104. And when the writable partition finishes upgrading and the current system is restarted, upgrading the non-writable partition.
In this embodiment, when the writable partition in the current system is upgraded by using the upgrade compression package and the terminal device is restarted, the writable partition in the current system may be upgraded. At this time, since the system is restarted, the new authority of the unwritable partition is already in effect, that is, the unwritable partition is changed into the writable partition, so that the upgrade program can perform write operation on the unwritable partition (changed into the writable partition) to complete update and upgrade.
That is, the reboot at this time is for the newly written content to take effect, the newly written content including the content of the writable partition upgrade and the rights of the modified non-writable partition. When restarted, the original non-writable partition actually becomes a writable partition.
The embodiment of the invention provides a system upgrading method, which comprises the steps that a system upgrading device receives a system upgrading instruction firstly, then whether each partition of a current system can be written or not is determined, the permission of a non-writable partition in the current system is modified to be writable by the system upgrading device, meanwhile, the writable partition in the current system is upgraded according to the system upgrading instruction, and when the writable partition is upgraded and the current system is restarted, the system upgrading device upgrades the non-writable partition. By the mode, the non-writable partition in the terminal equipment can be updated firstly, and then the system is upgraded after the updated writable partition, so that the problem of system upgrade of the non-writable partition is solved.
Optionally, on the basis of the embodiment corresponding to fig. 1, in a first optional embodiment of the method for upgrading a system according to the embodiment of the present invention, after upgrading the non-writable partition, the method may further include:
the current system of the terminal is restarted again.
In this embodiment, the system upgrading apparatus needs to restart the current system of the terminal if it is ensured that the upgrade content in the non-writable partition becomes valid after the non-writable partition is upgraded.
In the upgrading process, the system which leaves the factory and is of a past type cannot control the authority of the system, and the newly added content cannot be enabled to be effective. When the upgrade is completed and the system is restarted, the newly added content will take effect, that is, the system is the current system at the moment, that is, the upgrade package (upgrade content) is controllable, the upgrade process of the upgrade program is controlled through the upgrade script in the upgrade package, and meanwhile, the non-writable partition can be set as the writable partition.
Secondly, in the embodiment of the present invention, after the system upgrading device upgrades the non-writable partition, the current system of the terminal may be restarted again. By the aid of the method, the current system of the terminal equipment can be upgraded, the writable partition of the system is upgraded, and meanwhile the non-writable partition is upgraded, so that reliability and practicability of the scheme are improved.
Optionally, on the basis of the first embodiment corresponding to fig. 1, in a second optional embodiment of the method for upgrading a system according to the embodiment of the present invention, the method may further include:
when the current system has the non-writable partition, setting a mark A at any position of the writable partition of the current system;
when the non-writable partition finishes upgrading and takes effect, erasing the mark A or modifying the mark A into other marks except the mark A;
before restarting the current system of the terminal again, the method may further include:
it is determined that flag a is present in the current system.
In this embodiment, if the system upgrading apparatus determines that the current system still has the unwritable partition, a flag a is set at any position in the writable partition of the current system, that is, the flag a identifies that the current system has the unwritable partition, that is, the partition that has not been upgraded exists. Before the device for upgrading the system finishes the whole upgrading process, the current system of the terminal needs to be restarted, and the device for upgrading the system indicates that a partition which is not upgraded yet (the partition is upgraded but not validated) still exists in the current system under the condition that the flag A exists in the current system, so that the system is restarted, the partition which is upgraded completely is validated, then the flag A in the writable partition is erased, or the flag A is replaced by other flags, and the whole upgrading is finished.
In the embodiment of the present invention, how to verify whether the non-writable partition is updated to be valid by using the flag a is described, that is, when the non-writable partition exists in the current system, the flag a is set at any position of the writable partition of the current system, and then when the non-writable partition is updated and becomes valid, the flag a may be erased or modified to be other flags except for the flag a, and before the current system of the terminal is restarted, it is necessary to determine that the flag a exists in the current system. By the mode, the purpose of upgrading the unwritable partition at one time can be achieved, the device for upgrading the system firstly upgrades the partition which carries the mark A and can be written, then when the partition is restarted, the codes of the writable partition are effective, the device can find out whether the mark A exists, if the mark A exists, the upgrading program needs to be re-entered to upgrade the unwritable partition, namely, the system is upgraded for two times, if the mark A does not exist, the system does not need to be restarted again, namely, the system is upgraded for only one time, so that the purpose of upgrading the system at one time is achieved, and the operation convenience of the scheme is improved.
Optionally, on the basis of the first embodiment corresponding to fig. 1, in a third optional embodiment of the method for upgrading a system according to the embodiment of the present invention, before upgrading the non-writable partition, the method may further include:
and sending a reminding message whether to upgrade the non-writable partition.
In this embodiment, before the device for system upgrade upgrades the non-writable partition, a prompt message indicating whether to upgrade the non-writable partition may be sent in advance, where the prompt message is displayed on a terminal interface, and a user may manually select whether to upgrade the non-writable partition.
The reminding message may include a selection of "yes" or "no", which respectively indicates that the non-writable partition is upgraded and the non-writable partition is not upgraded, and may also be a "temporary non-reminding", and if the operation is selected, the reminding may be performed after a period of default, and the user may view the related service within the period of time.
In the embodiment of the present invention, before the non-writable partition is updated, the system updating apparatus may further send a prompt message indicating whether the non-writable partition is updated. Through the method, the user is inquired whether the non-writable partition needs to be upgraded or not, the user selects and operates the non-writable partition according to the actual condition instead of forcibly upgrading the non-writable partition, and therefore the practicability and flexibility of the scheme are improved.
Optionally, on the basis of any one of the first to third embodiments corresponding to fig. 1 and fig. 1, in a fourth optional embodiment of the method for upgrading a system according to the embodiment of the present invention, the method is specifically applied to remote upgrading.
In this embodiment, the present invention may be applied to local upgrade and remote upgrade. The remote upgrade is to operate the other party by remote assistance of a computer to upgrade the firmware of the current terminal.
In particular, there are various types of remote upgrades, and the remote upgrade employed by the present invention includes, but is not limited to, the following types.
Method one, uses simple batch commands. Firstly, establishing connection with an upgrade server, then copying an upgrade file from a server shared directory to a local directory, and finally deleting the connection with the upgrade server. The method has the advantages that the editing is simple, and only a simple small program for judging whether the database has a new version release is needed.
And secondly, establishing network connection and downloading files by using an Application Programming Interface (API). Firstly, judging whether a new version is released, if so, establishing connection with a server by using an API function, downloading an upgrade file by using other API functions or a file processing function provided by a development tool, then disconnecting the server by using the API function, and finally updating the version record of the local file.
And a third method is that a website is established, and the user can download the software of the new version by himself.
And fourthly, establishing a File Transfer Protocol (File Transfer Protocol, FTP) website to download the upgrade files in batches.
Furthermore, in the embodiment of the present invention, the scheme of the present invention may be specifically applied to remote upgrade, so that the scheme may be more reasonably applied, thereby improving the feasibility and the practicability of the scheme.
