Description

Memory distributor determination method and device, electronic equipment and storage medium

Technical Field

The application belongs to the technical field of communication, and particularly relates to a memory allocator determination method, a memory allocator determination device, electronic equipment and a storage medium.

Background

Currently, an operating system (e.g., an Android system) of an electronic device can only include one memory allocator (e.g., the memory allocator 1) to be responsible for allocating and managing a memory of the electronic device, so that processes running on the electronic device all use the memory allocator 1.

However, due to the differences in the mechanisms of different memory allocators, a part of the processes running on the electronic device is not suitable for using the memory allocator 1. For example: when the process 1 uses the memory distributor 1, the memory occupation is less and the process performance is poorer; however, since the application program corresponding to the process 1 is an important application program in the electronic device, the requirement on the performance of the process is high, and the requirement on the memory usage is low, the process 1 is not suitable for using the memory allocator 1; thus, the electronic device has low flexibility in using the memory allocator.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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 application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The memory allocator determination method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The memory allocator determining method in the embodiment of the application can be applied to a scenario where the memory allocator is used by the electronic device.

At present, in order to better manage a memory application of a user process, an operating system (e.g., an Android system) of an electronic device may manage a memory application of a user mode through a memory distributor, where the memory distributor brokers the user process to apply for and release a memory function through a malloc function, a calloc function, a free function, and the like, in recent years, the memory distributor used by the electronic device is mainly a Jemalloc memory distributor or a Scudo memory distributor, that is, the operating system of the electronic device may only include one memory distributor (e.g., a Jemalloc memory distributor) to be responsible for memory distribution and management of the electronic device, and therefore processes running on the electronic device are also processed by the jeloc memory distributor.

On one hand, however, the implementation mechanisms of different memory distributors have great difference, and the performance and memory occupation performance of the memory distributors also have certain difference; on the other hand, the operating system has a plurality of running processes, and the memory using modes of the plurality of processes are different; among the many processes run by the electronic device, some of the processes may be better suited to use the Jemalloc memory allocator, and some of the processes may be better suited to use the Scudo memory allocator. Therefore, in the prior art, the selection of the memory allocator cannot be realized by taking into account that all processes can use the allocator which is more suitable for the processes. The application provides a method for supporting multiple memory distributors by an operating system, and aims to provide a memory distributor which is more suitable for the service logic of a process and can be used by most processes running on the operating system.

In the scheme provided by the embodiment of the application, the electronic equipment can acquire information of a first process running in the electronic equipment; determining a target memory distributor from at least two memory distributors compatible with the electronic equipment according to the information of the first process; the target memory allocator is used for managing the memory of the first process, and the target memory allocator is matched with the first process. Because the electronic device can acquire the information of the first process running in the electronic device, the electronic device can determine a target content distributor matched with the first process from the at least two compatible content distributors according to the acquired information of the first process, that is, the electronic device can select one memory distributor suitable for the first process to be used as a target memory distributor to manage the memory of the first process, thereby improving the flexibility of the electronic device in using the memory distributor.

An embodiment of the present application provides a method for determining a memory allocator, and fig. 1 shows a flowchart of the method for determining a memory allocator provided in the embodiment of the present application. As shown in fig. 1, the memory allocator determination method provided in the embodiment of the present application may include

steps

201 and 202 described below.

Step 201, the electronic device obtains information of a first process running in the electronic device.

Optionally, in this embodiment of the application, the first process may be a process corresponding to any application program in the electronic device.

Optionally, in this embodiment of the application, the information of the first process may be an identifier of the first process, and the identifier of the first process may be understood as an identifier of an application program corresponding to the first process.

Step 202, the electronic device determines a target memory allocator from at least two memory allocators compatible with the electronic device according to the information of the first process.

The target memory allocator is used for managing the memory of the first process, and the target memory allocator is matched with the first process.

In this embodiment, the electronic device may search, according to the information of the first process, a target memory allocator matched with the first process from at least two memory allocators compatible with the electronic device, so as to manage the memory of the first process by using the target memory allocator after determining the target memory allocator.

It will be appreciated that the target memory allocator is the memory allocator that performs the best in running the first process.

Optionally, in this embodiment, before the step 202, the method for determining a memory allocator provided in this embodiment further includes the following step 301.

Step 301, the electronic device modifies the original compiling condition to obtain a target compiling condition.

Wherein, under the original compiling condition, the electronic device supports a memory distributor; under the condition of target compiling, the electronic equipment is compatible with at least two memory allocators.

Optionally, in this embodiment of the application, the modification of the original compiling condition is a modification of a Makefile script file, and the Makefile script file is used to control compiling content.

Optionally, in this embodiment of the present application, the electronic device may be compatible with at least two memory allocators through a standard function library (Libc) or another function library capable of storing memory allocators.

Optionally, in this embodiment of the present application, the memory allocator with which the electronic device is compatible may be at least two of the following: a Scudo memory distributor, a Jemalloc-4.1.0 memory distributor and a Jemalloc-5.1.0 memory distributor.

Alternatively, in this embodiment of the application, the step 202 may be specifically implemented by the following steps 202a to 202 c.

Step 202a, the electronic device calls a first interface according to the information of the first process.

In this embodiment, the first interface is implemented by a function related to memory allocation.

Optionally, in this embodiment of the present application, the first interface may be a memory allocation interface or a memory release interface.

Optionally, in this embodiment of the present application, the memory allocation interface may include: the function may be implemented by a malloc function, a calloc function, or a realloc function, or may be implemented by other functions responsible for memory allocation, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited.

Optionally, in this embodiment of the present invention, the memory release interface may be implemented by a free function, or may be implemented by other functions responsible for memory release, which may be specifically determined according to actual usage requirements, and the embodiment of the present invention is not limited.

Optionally, in this embodiment of the application, the first interface is a common interface, or may be understood as an interface that a process can directly call.

Step 202b, the electronic device calls a second interface through the first interface.

In this embodiment of the present application, the second interface is implemented by a function for searching the memory allocator.

Optionally, in this embodiment of the application, the second interface is an intermediate layer interface added between the first interface and the memory allocator interface, and the second interface is an interface corresponding to an operating system of the electronic device.

Optionally, in this embodiment of the present application, the second interface may be implemented by a vendor _ malloc function, a vendor _ calloc function, a vendor _ realloc function, or a vendor _ free function, or may also be implemented by another function having a function of looking up a memory allocator, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited.

Optionally, in this embodiment of the application, invoking the second interface by the electronic device through the first interface may be understood as: when the electronic device calls the first interface, the electronic device redirects or interfaces to the second interface to select the memory allocator for the first process through the second interface.

Optionally, in this embodiment of the application, the second interface is an interface corresponding to the first interface.

It can be understood that, when the first interface called by the electronic device is a memory allocation interface (for example, an interface realized by a calloc function), the second interface called by the first interface is an interface corresponding to the first interface (for example, an interface realized by a vendor _ calloc function); or, when the first interface called by the electronic device is a memory release interface (for example, an interface implemented by a free function), the second interface called by the first interface is an interface corresponding to the first interface (for example, an interface implemented by a vendor _ free function).

Step 202c, the electronic device determines a target memory allocator from the at least two memory allocators compatible with the electronic device through the second interface.

It is to be understood that, in the case that the electronic device is compatible with multiple memory allocators, the electronic device may determine, through the second interface, a memory allocator suitable for use by the first process from among the multiple memory allocators, so as to manage the memory of the first process.

Optionally, in this embodiment of the present application, the first interface is a memory allocation interface, and the target memory allocator is configured to allocate a memory for the first process. Or, the first interface is a memory release interface, and the target memory allocator is configured to release the memory of the first process.

Specifically, when the first interface is a memory allocation interface, the electronic device calls a second interface corresponding to the memory allocation interface through the first interface, and then after the second interface determines a target memory allocator corresponding to the first process, the electronic device allocates a memory to the first process through a target memory allocator interface corresponding to the first interface and responsible for allocating a memory.

For example: under the condition that a first interface called by the electronic equipment is realized by a malloc function, a second interface called by the electronic equipment through the first interface is an interface realized by a vendor _ malloc function, and then after the second interface determines that the target memory distributor is the Scud memory distributor, the memory can be distributed for the first process through the interface realized by the Scud-malloc function.

Specifically, when the first interface is a memory release interface, the electronic device calls a second interface corresponding to the memory release interface through the first interface, and then after the second interface determines a target memory allocator corresponding to the first process, the electronic device releases the memory for the first process through a target memory allocator interface corresponding to the first interface and responsible for releasing the memory.

For example: under the condition that a first interface called by the electronic equipment is realized by a free function, a second interface called by the electronic equipment through the first interface is an interface realized by a vendor _ free function, and then after the second interface determines that the target memory distributor is the Jemalloc memory distributor, the memory can be released for the first process through the interface realized by the Jemalloc-free function.

The embodiment of the application provides a memory allocator determining method, wherein electronic equipment can acquire information of a first process running in the electronic equipment; determining a target memory distributor from at least two memory distributors compatible with the electronic equipment according to the information of the first process; the target memory allocator is used for managing the memory of the first process, and the target memory allocator is matched with the first process. Because the electronic device can acquire the information of the first process running in the electronic device, the electronic device can determine a target content distributor matched with the first process from the at least two compatible content distributors according to the acquired information of the first process, that is, the electronic device can select one memory distributor suitable for the first process to be used as a target memory distributor to manage the memory of the first process, thereby improving the flexibility of the electronic device in using the memory distributor.

Optionally, in this embodiment of the application, the step 202 of determining, by the electronic device, the target memory allocator from the at least two memory allocators compatible with the electronic device may specifically be implemented by the following step 401 and step 402.

Step 401, the electronic device obtains a target result table.

In this embodiment of the present application, the target result table is used to indicate a corresponding relationship between a process and a memory allocator.

In the embodiment of the present application, the target result table includes at least one corresponding relationship, and each corresponding relationship is a corresponding relationship between one process and one memory allocator.

Step 402, in the case that the information of the first process exists in the target result table, the electronic device determines the memory allocator corresponding to the information of the first process in the target result table as the target memory allocator.

It can be understood that the electronic device may test the first process through at least two memory allocators to determine a memory allocator corresponding to the first process, and add the memory allocator to the target result table, so that the information of the first process exists in the target result table. That is, the target result table stores the corresponding relationship between each process and the most suitable memory allocator.

It should be noted that, for the specific implementation manner that the electronic device may test the first process through at least two memory distributors to determine the memory distributor corresponding to the first process and add the memory distributor to the target result table, the following embodiments are described, and details are not described here.

In this embodiment, the electronic device may obtain the target result table, and search the memory allocator corresponding to the first process in the target result table according to the information of the first process, so as to determine the target memory allocator.

Specifically, the electronic device may search the first process in the target result table through the second interface according to the information of the first process, and determine the memory allocator corresponding to the first process as the target memory allocator.

Exemplarily, as shown in table 1, the table includes identifiers of processes 1 to 5 and a memory allocator corresponding to each process, that is, includes 5 corresponding relationships; the electronic device may search, according to the information of the first process (e.g., process 3), the process 3 in the target result table through the second interface, and determine the memory allocator corresponding to the process 3 (e.g., memory allocator 2 corresponding to process 3) as the target memory allocator, so as to manage the memory of the process 3 through the memory allocator 2.

TABLE 1 (target results table)

	Process	Memory distributor
			1	Process 1	Memory distributor 1
2	Process 2	Memory distributor 1
			3	Process 3	Memory distributor 2
4	Process 4	Memory distributor 3
			5	Process 5	Memory distributor 2

Therefore, when the electronic device runs the first process and calls the first interface realized by the function related to the memory allocation, the second interface realized by the function of the memory allocator can be called through the first interface, so that the target memory allocator corresponding to the first process can be searched in the target result table through the second interface, and the memory of the first process is managed through the target memory allocator, thereby improving the flexibility of the electronic device in using the memory allocator.

Optionally, in this embodiment of the application, the step 202 of determining, by the electronic device, the target memory allocator from the at least two memory allocators compatible with the electronic device may specifically be implemented by the following step 501.

Step 501, in the case that the first process is determined to be not initially operated according to the information of the first process, the electronic device obtains a numerical value of a global variable of the first process, and determines a memory allocator corresponding to the numerical value of the global variable of the first process as a target memory allocator.

In the embodiment of the application, the value of one global variable corresponds to one memory allocator.

In the embodiment of the application, each process corresponds to a global variable (flag).

Optionally, in this embodiment of the present application, the electronic device may set, in advance, a correspondence between each memory allocator and a numerical value of the global variable according to at least two memory allocators with which the electronic device is compatible.

For example: the value of the global variable corresponding to the memory allocator 1 is 1; the value of the global variable corresponding to the memory allocator 2 is 2; the value of the global variable corresponding to memory allocator 3 is 3. That is, when the flag value is 1, the memory allocator 1 is indicated, when the flag value is 2, the memory allocator 2 is indicated, and when the flag value is 3, the memory allocator 3 is indicated.

It can be understood that the electronic device may read, according to the information of the first process, the value of the global variable of the first process from the values of the at least one global variable through the second interface, so as to determine the memory allocator corresponding to the value of the global variable of the first process as the target memory allocator.

Exemplarily, as shown in table 2, the table includes identifiers of processes 1 to 5 and values of global variables corresponding to each process, that is, includes 5 corresponding relationships; the electronic device may search, according to the information of the first process (e.g., process 3), a value of a global variable of the first process (e.g., process 3) through the second interface, and determine a memory allocator (e.g., memory allocator 2) corresponding to the value of the global variable of the process 3 (e.g., flag = 2) as a target memory allocator, so as to manage the memory of the process 3 through the memory allocator 2.

TABLE 2

	Process	Global variable values
			1	Process 1	Flag＝1
2	Process 2	Flag＝1
			3	Process 3	Flag＝2
4	Process 4	Flag＝3
			5	Process 5	Flag＝2

Therefore, the electronic device can acquire the numerical value of the global variable of the first process through the second interface, and determine the memory allocator corresponding to the numerical value of the global variable of the first process as the target memory allocator to manage the memory of the first process, so that the flexibility of the electronic device in using the memory allocator is improved.

Optionally, in this embodiment, before the step 401, the method for determining a memory allocator provided in this embodiment further includes the following step 601.

Step 601, the electronic device updates the value of the global variable corresponding to each process in the target result table according to the target result table.

The target result table is used for indicating the corresponding relation between the process and the memory allocator.

Optionally, in this embodiment of the application, for a process in the target result table (that is, a process of the determined corresponding memory allocator), the electronic device may update, according to a correspondence between the memory allocator and the value of the global variable, the value of the global variable corresponding to each process in the target result table.

It can be understood that, after the electronic device initially runs the first process and determines the target memory allocator corresponding to the first process through the target result table, the value of the global variable corresponding to the first process may be updated according to the correspondence between the memory allocator and the value of the global variable; when the electronic device runs the first process again, the value of the global variable of the first process can be directly obtained, so that the memory allocator corresponding to the value of the global variable of the first process is determined as the target memory allocator.

Therefore, the memory allocator corresponding to the first process can be determined without the electronic device searching for the target result table every time, and time consumption of the electronic device is reduced.

Optionally, in this embodiment of the application, the electronic device updates the value of the global variable corresponding to each process in the target result table, which may be understood as initializing the value of the global variable of each process, and when the value of the global variable of each process is not initialized, the value is 0.

Optionally, in this embodiment, before the step 201, the method for determining a memory allocator further includes the following steps 701 to 703.

Step 701, in the case that the test data related to the first process does not exist in the electronic device, the electronic device tests the first process in the electronic device through at least two memory distributors, and respectively obtains a score when the first process uses each memory distributor.

Optionally, in this embodiment of the present application, the electronic device may test a first process in the electronic device through at least two memory distributors, so as to obtain a performance score and a memory score when the first process uses each memory distributor.

Specifically, the electronic device may test, through the process training model, a process starting time, a process critical process time consumption, and the like when the first process uses at least two memory allocators, so as to obtain a performance score when the first process uses each memory allocator.

Specifically, in this embodiment, the electronic device may test, through the process training model, the process start memory occupancy when the first process uses at least two memory distributors, the process memory occupancy peak value, the process memory occupancy when the process resides on the background, and the like, so as to obtain the memory score when the first process uses each memory distributor.

Optionally, in this embodiment of the application, the electronic device may determine, according to the performance score and the memory score of the first process when using each memory allocator, the process performance weight of the first process, and the system memory weight of the electronic device, the score of the first process when using each memory allocator.

Optionally, in this embodiment of the application, the process performance weight of the first process may be set by a user according to the importance degree of the process.

Optionally, in this embodiment of the application, the system memory weight of the electronic device may be determined according to a memory of the electronic device.

For example, for an electronic device with a small memory (e.g., the memory is smaller than a threshold), the electronic device may set a higher system memory weight, so as to ensure that the memory of the electronic device is sufficient; for an electronic device with a large memory (e.g., a memory greater than a threshold), since the memory allocated to the process is sufficient, the electronic device may set a lower system memory weight to improve the performance of the electronic device.

Exemplarily, a process 1 and an electronic device are compatible with two memory distributors, the process 1 can test the performance score and the memory score when the process 1 uses the memory distributor 1 through a process training model, and then determine the score when the process 1 uses the memory distributor 1 according to the performance score and the memory score when the process 1 uses the memory distributor 1, and the process performance weight of the process 1 and the system memory weight of the electronic device, which are set by a user; the performance score and the memory score of the process 1 when the memory distributor 2 is used can be tested through the process training model, and then the score of the process 1 when the memory distributor 2 is used is determined according to the performance score and the memory score of the process 1 when the memory distributor 2 is used, the process performance weight of the process 1 set by a user and the system memory weight of the electronic equipment; and testing the performance score and the memory score when the process 1 uses the memory distributor 3 through the process training model, and then determining the score when the process 1 uses the memory distributor 3 according to the performance score and the memory score when the process 1 uses the memory distributor 3, and the process performance weight of the process 1 and the system memory weight of the electronic equipment, which are set by a user, so as to obtain a plurality of scores when the process 1 uses a plurality of memory distributors.

Optionally, in this embodiment of the application, for the score when each memory allocator is used in the first process, the electronic device may calculate by using the following formula:

total score (total _ score) = process performance weight (process _ perf _ weight _ coeffient) × performance score (perf _ score) + system memory weight (sys _ mem _ weight _ coeffient) × memory score (mem _ score).

For example: when the process 1 uses the memory allocator 1, the performance score is 6, the memory score is 8, the process performance weight of the process 1 is 1, and the system memory weight of the electronic device is 2, then the score when the process 1 uses the memory allocator 1 is: 1 × 6+2 × 8=22 minutes.

Step 702, the electronic device determines a memory allocator corresponding to a maximum score among the plurality of scores as a target memory allocator corresponding to the first process.

It can be understood that after the first process uses the plurality of memory distributors to perform the test, a plurality of different scores can be obtained, and then the electronic device can determine the memory distributor corresponding to the largest score among the plurality of scores as the target memory distributor corresponding to the first process.

Step 703, the electronic device associates the first process with the target memory allocator corresponding to the first process, and adds the first process to the target result table.

Therefore, when the subsequent electronic equipment runs the first process, the target memory distributor corresponding to the first process can be determined according to the target result table, and the memory of the first process is managed through the target memory distributor, so that the accuracy of the electronic equipment in using the memory distributor is improved.

Optionally, in this embodiment of the application, the target result table includes an identifier of at least one process and an identifier of at least one memory allocator, and each memory allocator corresponds to one process.

Optionally, in this embodiment of the present application, a part of processes (for example, processes corresponding to a computer application) in an electronic device are non-critical processes, and when different distributors are used, differences between performance and memory usage are not large, so that the electronic device may not participate in a test, and a default distributor of the electronic device is used to manage a memory, where the default distributor may be any one of at least two memory distributors compatible with the electronic device.

Optionally, in this embodiment of the application, the target result table may be updated following a system version update of the electronic device. It can be understood that, when the system of the electronic device is updated, the electronic device may retest the processes in the electronic device through the at least two memory distributors, so as to update the target result table according to the test result.

Optionally, in this embodiment of the present application, the method for determining a memory allocator provided in this embodiment of the present application may further include the following steps 801 to 803.

Step 801, displaying a target setting interface by the electronic equipment.

In this embodiment, the target setting interface includes an identifier of at least one process and an identifier of at least one memory allocator, and each memory allocator corresponds to one process.

Optionally, in this embodiment of the application, the electronic device may provide a function of setting the process memory allocator in the setting interface or the housekeeping application program, and the user may perform input to trigger the electronic device to display an interface (i.e., a target setting interface) for setting the process memory allocator.

Step 802, an electronic device receives a first input of a user.

In an embodiment of the present application, the first input is an input used to modify a memory allocator corresponding to the target process.

Optionally, in this embodiment of the present application, the target process may be a process that is already trained or a process that is not trained.

It can be understood that, a user may download some new applications through the application store application, processes corresponding to the applications are not trained through the process training model, and the electronic device defaults to use the default memory allocator for the processes, so that the user may trigger the electronic device to train the processes to obtain the memory allocators corresponding to the processes.

It should be noted that, for the description of the process of training the processes by the electronic device, reference may be made to the description of the process of testing the first process in the foregoing embodiment, which is not described herein again.

Optionally, in this embodiment of the application, the target setting interface may include a first control, where the first control is used to trigger an electronic device to train a target process.

Optionally, in this embodiment of the application, the first input may be a touch input (for example, a click input, a drag input, a slide input, or the like) or other feasible input performed by the user on the first control, so as to trigger the electronic device to modify the memory allocator corresponding to the target process, and update the identifier of the memory allocator corresponding to the target process in the target setting interface, which is not limited in this embodiment of the application.

Step 803, the electronic device responds to the first input, modifies the memory allocator corresponding to the target process, and updates the identifier of the memory allocator corresponding to the target process in the target setting interface.

Optionally, in this embodiment of the application, after the electronic device trains the target process, the memory allocator corresponding to the target process in the target result table may be updated at the same time.

Therefore, the flexibility of the memory allocator used by the target process determined by the electronic equipment is improved.

It should be noted that, in the memory allocator determination method provided in the embodiment of the present application, the execution subject may be an electronic device, or a memory allocator determination device, or a control module in the memory allocator determination device.
