Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the disclosure provides a cache processing method, which can be applied to electronic equipment. Fig. 1 is a first flowchart illustrating a caching process according to an exemplary embodiment, and as shown in fig. 1, the method mainly includes the following steps:
in step 101, obtaining a current memory state of the electronic device;
in step 102, it is determined whether to start a thread local cache function of the application program process according to the cache policy corresponding to the current memory state.
The cache processing method in the embodiments of the present disclosure may be applied to an electronic device, where the electronic device includes a terminal device, such as a mobile terminal and a fixed terminal, where the mobile terminal includes: mobile phones, tablet computers, notebook computers, and the like; the fixed terminal includes: a personal computer. In other optional embodiments, the cache processing method may also be applied to an embedded electronic device configured with an Android operating system.
Here, the current memory state may include: the memory state of the electronic equipment in the starting process and the memory state of the electronic equipment after the electronic equipment is successfully started. After the current memory state of the electronic equipment is obtained, a cache strategy corresponding to the current memory state can be determined, and whether a thread local cache function of an application program process is started or not is determined according to the cache strategy.
In some embodiments, the electronic device has a set type of operating system, and a corresponding memory allocator may be configured for the operating system, and the memory allocator is configured with a thread local cache function. For example, if the operating system of the set type is an Android operating system, the memory allocator may be a Jemalloc, and correspondingly, the memory allocator is configured with a thread local cache function. In the implementation process, if the thread local cache function is started, a corresponding thread local cache region can be configured for each thread, and the object of each thread is stored based on the local cache region.
Taking the electronic device as an example, which is an electronic device with an Android operating system, the Android operating system may use the Jemalloc as a memory allocator because the Jemalloc has excellent multithreading concurrent allocation performance. The memory consumption of the electronic device is increased due to the fact that the thread local cache function is continuously started, in the implementation process, the current memory state of the electronic device can be obtained, and whether the thread local cache function of the application program process is started or not is determined according to the cache strategy corresponding to the current memory state.
For example, the total memory of the electronic device may be obtained, and when the total memory of the electronic device is greater than or equal to the first set memory, the thread local cache function of all application processes in the electronic device is started. For another example, the thread local cache function of all application program processes in the electronic device may be turned off when the total memory of the electronic device is smaller than the first set memory.
In the embodiment of the disclosure, whether to start the thread local cache function of the application program process may be determined by obtaining the current memory state of the electronic device and according to the cache policy corresponding to the current memory state. Compared with the prior art that the cache policy is determined during the compiling period, and the thread local cache function of the application program process is opened or closed according to the fixed cache policy, in the embodiment of the disclosure, the cache policy can be flexibly adjusted according to the memory state of the electronic device, that is, the thread local cache function of the application program process is opened or closed according to the memory state of the electronic device, and the dynamic adjustment of the cache policy can be realized.
In some embodiments, the obtaining the current memory state of the electronic device includes:
when a starting instruction for starting the electronic equipment is detected, acquiring a total memory of the electronic equipment;
the determining whether to start a thread local cache function of the application program process according to the cache policy corresponding to the current memory state includes:
and starting the thread local cache function of all the application program processes in the electronic equipment under the condition that the total memory is greater than or equal to a first set memory.
Here, the opening instruction may be an instruction triggered by a user based on a control on the electronic device, where the control may be a virtual control or a physical button. In the embodiment of the present disclosure, when the electronic device detects the opening instruction, the electronic device may be started, and when the electronic device is started, the total memory of the electronic device is obtained.
For example, the total memory of the electronic device may be read by a first process started in the process of booting the electronic device. For another example, the total memory of the electronic device may be read based on the init () function during the booting process of the electronic device.
After the total memory of the electronic device is obtained, the total memory of the electronic device may be compared with a first set memory to obtain a first comparison result, and whether to start a thread local cache function of an application program process in the electronic device is determined according to the first comparison result.
For example, when the first comparison result indicates that the total memory of the electronic device is greater than or equal to the first set memory, the thread local cache function of all application program processes in the electronic device is started. Since the memory of the electronic device is consumed by starting the local cache function, in the embodiment of the present disclosure, the thread local cache function of all application processes is started under the condition that the total memory of the electronic device is sufficient, and the running speed of the application can be ensured on the basis of ensuring that the available memory of the electronic device is sufficient.
In other embodiments, the thread local cache function of a part of the application program processes in the electronic device may be started when the total memory of the electronic device is greater than or equal to the first set memory. For example, when the total memory of the electronic device is greater than or equal to the first set memory, the thread local cache function of N application program processes in the electronic device may be turned on, where N may be set as needed, for example, 3 or 5, and the like, and is not limited herein.
In the embodiment of the disclosure, the total memory of the electronic device can be acquired and evaluated in the starting process of the electronic device, and the thread local cache function of all or part of the application program processes in the electronic device is started again under the condition that it is determined that the total memory is enough to ensure that the electronic device can normally run after the thread local cache function is started, so that the memory occupation and allocation of the electronic device can be balanced.
In some embodiments, the determining whether to start a thread local caching function of an application program process according to a caching policy corresponding to the current memory state includes:
and closing the thread local cache function of all application program processes in the electronic equipment under the condition that the total memory is smaller than the first set memory.
In other embodiments, the thread local cache function of a part of the application program processes in the electronic device may be turned off when the total memory of the electronic device is smaller than the first set memory. For example, in a case that the total memory of the electronic device is smaller than the first set memory, the thread local cache function of K application processes in the electronic device may be turned off, where K may be set as needed, for example, K may be 2 or 6, and the like, and is not limited in this respect.
In the embodiment of the disclosure, in the starting process of the electronic device, the total memory of the electronic device can be acquired and evaluated, and under the condition that it is determined that the total memory is not enough to ensure that the electronic device can normally operate after the thread local cache function is started, the thread local cache function of all or part of the application program processes in the electronic device is closed, so that the balance of memory occupation and allocation of the electronic device can be realized.
In some embodiments, the method further comprises:
when the electronic equipment runs, acquiring a current available memory of the electronic equipment;
the determining whether to start a thread local cache function of the application program process according to the cache policy corresponding to the current memory state includes:
and under the condition that the current available memory is less than or equal to a second set memory, maintaining the thread local cache function of the application program process in the starting state in an opening state, and closing the thread local cache function of the application program process to be started.
Here, in the process of operating the electronic device, a currently available memory of the electronic device may be obtained, where the currently available memory may refer to a memory that is not currently occupied in the electronic device. In the embodiment of the disclosure, in the using process of the electronic device, the current available memory of the electronic device may be obtained, the current available memory is compared with the second set memory to obtain a second comparison result, and whether the thread local caching function performed by the application program is started is determined according to the second comparison result.
For example, when the second comparison result indicates that the current available memory is less than or equal to the second set memory, the thread local cache function of the application program process in the starting state may be maintained in the open state, and the thread local cache function of the application program process to be started may be closed.
In the embodiment of the disclosure, in the running process of the electronic device, the current available memory of the electronic device may be obtained, and the current available memory is evaluated, and under the condition that it is determined that the current available memory is not enough to ensure that the electronic device can run normally on the basis of starting the thread local cache function, the thread local cache function of the application program process in the starting state may be maintained in the starting state, and the thread local cache function of the application program process to be started is closed, so that the balance of memory occupation and allocation of the electronic device can be realized.
In some embodiments, the determining whether to start a thread local caching function of an application program process according to a caching policy corresponding to the current memory state includes:
and maintaining the thread local cache functions of all application program processes in the electronic equipment in an open state under the condition that the current available memory is larger than the second set memory.
In the embodiment of the disclosure, in the process of operating the electronic device, the current available memory of the electronic device may be obtained and evaluated, and under the condition that it is determined that the current available memory is sufficient to ensure that the electronic device can normally operate on the basis of starting the thread local cache function, the thread local cache functions of all application program processes in the electronic device may be maintained in the starting state, so that the memory occupation and allocation of the electronic device may be balanced.
In some embodiments, for example, the electronic device is an electronic device with an Android operating system, since the Jemalloc has excellent multithreading concurrent allocation performance, the Android operating system may use the Jemalloc as a memory allocator.
The Jemalloc uses a thread local cache function to improve the multithreading concurrent allocation performance so as to avoid performance loss caused by synchronization among multiple threads, but the memory consumption is increased by starting the thread local cache function. In the related art, the thread local cache function is turned on by default, for example, the Jemalloc selects to turn on or turn off the thread local cache function during compilation by default, for example, the thread local cache function can be selected to be turned off on an electronic device with a low memory configuration to save memory consumption. In the related technology, the Jemalloc defines a macro variable for determining whether to start the local cache function of the thread in a compiling script, the Jemalloc determines whether to start the local cache function of the thread in an initialization code according to whether the macro variable is set, and in the implementation process, the compiling script needs to be modified to achieve the purpose of starting or closing the local cache function of the thread.
Generally, a plurality of memory configurations exist in an electronic device product, for example, the same mobile phone may have a 2G, 3G or 4G memory, and in the implementation process, the mobile phone having the 2G and 3G memory configurations needs to turn off the thread local cache function to save the memory, while the mobile phone having the 4G memory configuration may turn on the thread local cache function to obtain better performance. The Jemalloc default is that the thread local cache function is selected to be started or closed during compiling, and differential configuration cannot be carried out on the same electronic equipment with different memories.
In the Android operating system, the Jemalloc cannot dynamically adjust the cache policy according to the memory pressure of the electronic device during the use process, for example, when the memory pressure is high, the thread local cache function is closed for the newly started process, and when the memory pressure is low, the thread local cache function is opened for the newly started process.
In some embodiments, the technical solution in the embodiments of the present disclosure is composed of three parts, Jemalloc, libc, and Framework. In the implementation process, the configuration function of the global variable of the memory allocator for controlling the thread local cache function can be modified from read-only at run-time to readable and writable at run-time. For example, the configuration function of the global variable OPT _ TCACHE in the config module of the Jemalloc, which controls the thread local caching function, can be modified from read-only at runtime to readable and writable at runtime, and a parameter option OPT _ TCACHE is newly added in the mallop function of libc, so as to modify the global variable OPT _ TCACHE of the Jemalloc in the case of a single thread, so as to close or open the thread local caching function.
Fig. 2 is a schematic flow chart of a caching process according to an exemplary embodiment, where as shown in fig. 2, the method mainly includes the following steps:
in step 201, the total memory of the electronic device is read.
Here, the total memory of the electronic device may be read by a first process started in the process of booting the electronic device. For another example, the total memory of the electronic device may be read based on the init () function during the booting process of the electronic device.
In step 202, it is determined whether the total memory of the electronic device is less than a first set memory.
Here, the thread local cache function may be turned on or off according to the total memory of the electronic device. For example, after the total memory of the electronic device is obtained, the total memory of the electronic device may be compared with a first set memory to obtain a first comparison result, and whether to start a thread local cache function of an application program process in the electronic device is determined according to the first comparison result. For example, when the total memory is smaller than the first set memory, the thread local cache function of all application program processes in the electronic device is turned off.
In step 203, if the total memory is less than the first set memory, the attribute ro.
Here, if the thread local cache function needs to be turned off, the attribute ro.
In step 204, the init process fork (spawn) child process.
In step 205, it is determined whether the ro.
In step 206, if the ro.
Here, in the subsequent boot process, if the child process of the init process fork reads that the ro.
In step 207, if the ro, boot, disable, tcache attribute read by the sub-process is not true, the libc will be reinitialized when the sub-process executes a new executable file using exec system call.
In step 208, it is determined whether the environment variable JEMALLOC _ DISABLE _ TCACHE is 1.
Here, it is possible to read the environment variable JEMALLOC _ DISABLE _ TCACHE during libc initialization and determine whether the environment variable JEMALLOC _ DISABLE _ TCACHE is 1.
In step 209, if the JEMALLOC _ DISABLE _ TCACHE environment variable exists and has a value of 1, the global variable opt _ TCACHE that determines whether the thread local cache is open is directly set to false to turn off the thread local cache function.
In some embodiments, since an Android Application (App) comes out through a zygate process fork and zygate comes out through an init process fork, the thread local cache of all subsequent Application processes is closed as long as the thread local cache function of the zygate process is closed during the starting process of the electronic device (e.g., a mobile phone).
Fig. 3 is a schematic flow chart of a caching process according to an exemplary embodiment, where as shown in fig. 3, the method mainly includes the following steps:
in step 301, a zygate process is requested to start a new application process.
In step 302, a fork sub-process is based on the zygate process.
In step 303, it is determined whether the currently available memory of the electronic device is less than or equal to a second set memory.
In step 304, when the current available memory of the electronic device is less than or equal to the second set memory, a newly added mallopt option OPT _ TCACHE is used to set a global variable OPT _ TCACHE that determines whether the thread local cache is opened to false, so as to close the thread local cache function.
Here, taking the electronic device as a mobile phone as an example, during the use of the mobile phone, whether to turn on or turn off the thread local cache function of the newly started application program process may be determined according to the overall memory state of the mobile phone. For example, if the current overall memory state is poor, the thread local cache function of the newly started application program process may be closed, so as to save the memory.
In some embodiments, when the application program process from the zygate process fork is in a single-thread state, the global variable OPT _ TCACHE that determines whether the thread local cache is opened may be set to false using the newly added mallopt option OPT _ TCACHE, so as to close the thread local cache function.
In some embodiments, the cache policy may be adjusted according to the overall memory state of the electronic device during the startup process of the electronic device. Or taking the electronic device as a mobile phone as an example, if a certain mobile phone has two configurations of 3G and 4G memories, and the two configurations of the two memories are the same software package, in the implementation process, by modifying the Jemalloc underlying function, the thread local cache function is opened or closed when the mobile phone supports running, and the actual memory size (total memory) of the mobile phone is determined in the starting process of the mobile phone, and whether the thread local cache function is opened or not is determined based on the actual memory size. For example, the thread local cache function is closed for all application program processes in a 3G mobile phone, and the thread local cache function is opened for all application program processes in a 4G mobile phone.
In other embodiments, the cache policy may be adjusted according to the overall memory state of the electronic device during the operation of the electronic device. Taking the electronic device as a mobile phone as an example, in the running process of the mobile phone, the cache policy may be adjusted according to the overall memory state of the mobile phone, for example, the current memory state of the mobile phone may be monitored, the thread local cache function may be closed for a newly started application program process when the memory pressure is high, and the thread local cache function may be opened for the newly started application program process when the memory pressure is low.
According to the technical scheme, on one hand, the problem of how to determine whether to start or close the thread local cache function of all application program processes of the system according to the memory size or other state information when the electronic equipment runs is solved. On the other hand, the problem of how to open the thread local cache function for part of the application program processes according to a specific strategy and close the thread local cache function for the other part of the application program processes is solved. By adopting the technical scheme, the balance of memory occupation and allocation is realized, 60-100M memory can be saved by the electronic equipment configured by the 2G memory, and 100-300M memory can be saved by the electronic equipment configured by the 3G memory.
