Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "include" and variations thereof as used herein are open-ended, i.e., "including but not limited to". The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The term "responsive to" and related terms mean that one signal or event is affected to some extent, but not necessarily completely or directly, by another signal or event. If an event x occurs "in response" to an event y, x may respond directly or indirectly to y. For example, the occurrence of y may ultimately result in the occurrence of x, but other intermediate events and/or conditions may exist. In other cases, y may not necessarily result in the occurrence of x, and x may occur even though y has not already occurred. Furthermore, the term "responsive to" may also mean "at least partially responsive to". The term "determining" broadly encompasses a wide variety of actions that can include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like, and can also include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like, as well as resolving, selecting, choosing, establishing and the like. Relevant definitions for other terms will be given in the following description.
It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.
It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.
In the following, several technical terms related to the present disclosure will be explained first.
1. Hotspot Code (Hot Spot Code)
Hotspot code may refer to code that is executed more than a preset threshold number of times during application startup or use, including but not limited to functions, methods, code blocks, classes, and the like. For example, in a Client mode, the android system takes codes with execution times exceeding 1500 as hot spot codes; in a Server (Server) mode, the android system takes code with execution times exceeding 10000 as hot spot code.
2. Native Code (Native Code)
The native code is computer programming code that is compiled to run a particular processor (e.g., an intel x86 class processor) and its particular instruction set. Native code is code that has been compiled into processor-specific machine code and can be executed directly by a virtual machine.
3. Precompilation or AOT compilation (Ahead-of-time compilation)
Precompilation refers to the act of converting a higher level programming language (such as C or C + +) or intermediate code (such as Java bytecode or. NET Framework Common Intermediate Language (CIL) code) into native code to generate a binary file that can be natively executed. Compiling intermediate code during program execution (e.g., Just-in-time compilation) may degrade the performance of the application, while pre-compiling eliminates the need for this step by occurring before execution rather than during execution.
The compiling method provided by one or more embodiments of the present disclosure is applied to terminals, including but not limited to, devices such as televisions, smart screens, mobile phones, computers, electronic readers, PDAs (personal digital assistants), PADs (tablet computers), and the like; the terminal is provided with a first operating system and a second operating system, the first operating system corresponds to a first system partition, and the second operating system corresponds to a second system partition. The first operating system and the second operating system may be the same version or different versions of the same operating system.
In some embodiments, the first system partition and the second system partition may be two separate sets of system partitions. Illustratively, each set of system partitions includes a respective boot partition, system partition, vendor partition, and the like.
In some embodiments, the terminal currently runs the first operating system, and referring to fig. 1, a compiling method 100 provided based on one or more embodiments of the present disclosure is shown, where the compiling method 100 includes:
step S101: updating the second operating system and mounting the second system partition after the second operating system is updated;
in this step, after the second operating system is updated, the second system partition is mounted so that the file of the second system partition can be accessed, which is equivalent to that the terminal runs the first operating system and the second operating system at the same time.
In some embodiments, the system update data may be obtained and written to the second system partition based on the first operating system currently running on the terminal. It should be noted that, when the system update data is written into the second system partition, the second system partition is not yet mounted, that is, only the first operating system is mounted on the current terminal, and only the first operating system is in an active state.
Illustratively, the terminal may download the system update package on the remote server via Over-the-Air (OTA) technology and write the system update package to the second system partition.
Step S102: the method comprises the steps of obtaining a hotspot description file of at least one application program, wherein the hotspot description file is used for recording hotspot codes of the application program.
Illustratively, the hotspot description file is a profile file, which is used to record hotspot codes of an application program and can be used for profile-guide compilation.
In some embodiments, the hotspot description files are stored in respective directories of the corresponding application programs, and the directories of the application programs are located in a user data (userdata) partition. The user data partition is used for storing user data, including application programs installed by users and data generated in use; the user data partition may be shared by the first operating system and the second operating system.
Further, in some embodiments, a hotspot description file for at least one application may be obtained from the user data partition.
It should be noted that, in this step, the hotspot description files of all the application programs installed in the terminal may be obtained, and also the hotspot description file of one or more specific application programs may be obtained, which is not limited in this disclosure.
Step S103: before the terminal is restarted, compiling the hot spot codes of at least one application program according to the hot spot description file based on the updated second operating system so as to generate native codes executed under the second operating system.
Illustratively, AOT compilation may be employed to compile dalvik bytecodes (dalvik bytecodes) as hot spot codes in the dex file into assembly instructions that the processor can recognize for execution, i.e., Native codes.
It should be noted that, in this step, hot spot codes of all application programs installed in the terminal may be compiled, and also hot spot codes of one or more specific application programs may be compiled, which is not limited herein.
In some embodiments, the generated native code may be saved in a specific folder, preventing the native code from being deleted as a result of the terminal restarting to run the updated operating system. Illustratively, the particular folder may be located in the second system partition.
According to the compiling method provided by one or more embodiments of the disclosure, before the terminal is restarted after the second operating system is updated, the hotspot codes of the application program are compiled by using the hotspot description file of the second operating system based on the application program to generate the native codes executed under the second system, so that the problem that the hotspot description file cannot be compiled in time due to the fact that the system is updated and deleted can be avoided, the hotspot codes used by a new system can be compiled during the system updating period, and the hotspot codes are compiled without waiting until the terminal is in a charging and idle state, so that the native codes can be compiled at the first time, and the application performance can be improved in time.
In some embodiments, the method 100 further comprises:
step S104: restarting the terminal;
illustratively, the first operating system may pop up a dialog box whether to restart, and restart the terminal in response to a user confirming an instruction to restart.
Step S105: after the terminal is restarted, loading the updated second operating system;
step S106: and storing the native code into a directory of a corresponding application program.
In this embodiment, after the terminal is restarted, the second operating system is started from the second system partition, and the first system partition is not mounted, so that switching from the first operating system to the updated second operating system is completed, and the compiled native code is stored in the directory of the corresponding application program, so that the native code can be directly executed when the updated second operating system is started and uses the corresponding application program, thereby improving the performance of the application program in time.
In some embodiments, the terminal is configured to alternately update the first system partition and the second system partition, so that the updated system can be provided with the native code of each application program by performing the steps at each system update, thereby improving the performance of the application program.
In some embodiments, the first operating system and the second operating system are a/B systems of an android platform.
The A/B system update (also called seamless update) of the android platform ensures that a system which can be normally started and used is reserved on a disk during the update of a wireless download (OTA) by setting two sets of system partitions (a slot A and a slot B) so as to reduce the possibility that a device cannot be started after the update. Under an A/B system, the system runs from the "current" slot, but during normal operation, the running system does not access partitions in unused slots. The method prevents the update problem by reserving the unused slot position as the backup slot position: if an error occurs during or just after the update, the system may roll back to the original slot and continue normal operation. Thus, in the A/B system of the android platform, only one system partition is mounted at the same time.
In contrast, according to one or more embodiments of the present disclosure, by modifying the system partition mount logic of the a/B system of the android platform, when the first system partition is mounted, the second system partition is mounted simultaneously after the second operating system is updated, so that the hot point code of the application can be compiled by the second operating system according to the hot point description to generate a native code executed under the second operating system, thereby achieving the completion of the compilation of the native code during the "seamless update" of the system, and it is not necessary to compile the hot point code again until the updated terminal is again in the charging and idle state, so that the compilation of the native code can be completed at the first time, and the application performance can be improved in time.
Referring to fig. 2, fig. 2 illustrates a compiling method 200 provided based on another embodiment of the present disclosure, applied to a terminal installed with a first operating system and a second operating system, where the first operating system corresponds to a first system partition, and the second operating system corresponds to a second system partition; the terminal has a user data partition shared by the first operating system and the second operating system; the compiling method 200 comprises the following steps:
step S201: under the condition that the terminal is mounted with the first system partition, acquiring a system update package based on the first operating system, and writing the system update package into the second system partition;
step S202: after the system updating package is written, mounting the second system partition;
step S203: acquiring a hotspot description file of at least one application program from a user data partition;
step S204: compiling the hot spot codes of at least one application program according to the hot spot description file based on the updated second operating system so as to generate native codes executed under the second operating system;
step S205: restarting the terminal;
step S206: after the terminal is restarted, starting the updated second operating system from the second system partition, and not mounting the first system partition;
step S207: and storing the native code into a directory of a corresponding application program.
According to the compiling method provided by one or more embodiments of the disclosure, in the case that the first system partition is mounted, after the second operating system is updated, the second system partition is mounted at the same time, so that the second operating system can be used for compiling the application program based on the hotspot description file of the application program in the shared user data partition to generate native codes, the second operating system loaded after the terminal is restarted can execute the native codes, therefore, the problem that the hotspot description file cannot be compiled in time due to the fact that the system is updated and deleted can be avoided, the hotspot codes used by a new system can be compiled during the seamless updating period of the system, and the hotspot codes are not required to be compiled until the terminal is in a charging and idle state, so that the compiling of the native codes can be completed at the first time, and the application performance can be improved in time.
Correspondingly, fig. 3 illustrates a compiling apparatus 300 provided based on one or more embodiments of the present disclosure, which is applied to a terminal, and the terminal is installed with a first operating system and a second operating system; the first operating system corresponds to a first system partition, and the second operating system corresponds to a second system partition; the terminal currently runs the first operating system; the apparatus 300 comprises:
a second system mount unit 301, configured to update the second operating system and mount the second system partition after the second operating system is updated;
a description file obtaining unit 302, configured to obtain a hotspot description file of at least one application, where the hotspot description file is used to record a hotspot code of the application;
and a compiling unit 303, configured to compile, based on the updated second operating system, a hot spot code of at least one application program according to the hot spot description file before the terminal is restarted, so as to generate a native code executed under the second operating system.
According to the compiling device provided by one or more embodiments of the disclosure, before the terminal is restarted after the second operating system is updated, the hotspot codes of the application program are compiled by using the hotspot description file of the second operating system based on the application program to generate the native codes executed under the second system, so that the problem that the hotspot description file cannot be compiled in time due to the fact that the system is updated and deleted can be avoided, the hotspot codes used by a new system can be compiled during the system updating period, and the hotspot codes are compiled without waiting until the terminal is in a charging and idle state, so that the native codes can be compiled at the first time, and the application performance can be improved in time.
In some embodiments, the terminal has a user data partition shared by the first operating system and the second operating system; the hotspot description file is stored in the user data partition; the description file obtaining unit 302 is further configured to obtain a hotspot description file of at least one application from the user data partition.
In some embodiments, the apparatus 300 further comprises:
the restarting unit is used for restarting the terminal;
the second system loading unit is used for loading the updated second operating system after the terminal is restarted;
and the saving unit is used for saving the native code into a directory of the corresponding application program.
In this embodiment, after the terminal is restarted, the second operating system is started from the second system partition, and the first system partition is not mounted, so that switching from the first operating system to the updated second operating system is completed, and the compiled native code is stored in the directory of the corresponding application program, so that the native code can be directly executed when the updated second operating system is started and uses the corresponding application program, thereby improving the performance of the application program in time.
In some embodiments, the first operating system and the second operating system may be the same version or different versions of the same class of operating system.
In some embodiments, the second system mount unit 302 includes:
an update data acquisition unit configured to acquire system update data based on the first operating system;
and the data writing unit is used for writing the system updating data into the second system partition.
In some embodiments, the terminal is configured to alternately update the first system partition and the second system partition, so that the compiling apparatus provided according to the embodiments of the present disclosure can enable the updated system to have native codes of respective application programs, thereby improving the performance of the application programs.
In some embodiments, the first operating system and the second operating system are a/B systems of an android platform.
The A/B system update (also called seamless update) of the android platform ensures that a system which can be normally started and used is reserved on a disk during the update of a wireless download (OTA) by setting two sets of system partitions (a slot A and a slot B) so as to reduce the possibility that a device cannot be started after the update. Under an A/B system, the system runs from the "current" slot, but during normal operation, the running system does not access partitions in unused slots. The method prevents the update problem by reserving the unused slot position as the backup slot position: if an error occurs during or just after the update, the system may roll back to the original slot and continue normal operation. Thus, in the A/B system of the android platform, only one system partition is mounted at the same time.
In contrast, according to the compiling device provided in one or more embodiments of the present disclosure, by modifying the system partition mount logic of the a/B system of the android platform, when the first system partition is mounted, the second system partition is mounted simultaneously after the second operating system is updated, so that the hot point code of the application can be compiled by the second operating system according to the hot point description, so as to generate the native code executed under the second operating system, thereby achieving the purpose of completing the compiling of the native code during the "seamless update" of the system, and without waiting until the updated terminal is in the charging and idle state again, the hot point code can be compiled again, so that the compiling of the native code can be completed at the first time, and the application performance can be improved in time.
For the embodiments of the apparatus, since they correspond substantially to the method embodiments, reference may be made to the partial description of the method embodiments for relevant points. The above-described apparatus embodiments are merely illustrative, in that modules illustrated as separate modules may or may not be separate. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.
Accordingly, according to one or more embodiments of the present disclosure, there is provided a terminal device including:
at least one memory and at least one processor;
wherein the memory is used for storing program codes, and the processor is used for calling the program codes stored in the memory to execute the compiling method provided by one or more embodiments of the disclosure.
