Detailed Description
The following describes in detail specific embodiments of a memory recovery method, device, apparatus, and medium according to an embodiment of the present invention with reference to the accompanying drawings.
It should be noted that the memory recovery scheme provided in the embodiment of the present invention is not only applicable to the android system used in the vehicle-mounted central control system, but also applicable to other android systems in a long-term operating state or other operating systems with memory leakage.
As shown in fig. 1, the memory recycling method provided in the embodiment of the present invention may include the following steps:
The process identification is used for uniquely identifying each process, and the process identifications of different processes are different. In a specific implementation, the process identifier may be a process identifier of each process, or a process name of each process, or may be a combination of multiple attribute features of each process, for example, the process identifier may be a combination of a process identifier and a process name of each process, which is not limited in this embodiment of the present invention.
In a possible implementation manner, when the process identifier and the actually used physical memory of each process in the running state in the system are acquired, the process identifier and the actually used physical memory of each process in the running state in the system may be triggered to be acquired under the condition that the allocable physical memory space of the system is smaller than the preset space threshold, so as to reduce the system computation amount and reduce the influence on the user. The preset space threshold may be flexibly set according to the size of the system memory space, for example, the preset space threshold is set to 500 Mega (MB).
In another possible implementation manner, when the process identifier and the actually used physical memory of each process in the running state in the system are obtained, each process in the running state may be periodically traversed in the running process of the system, and the process identifier and the actually used physical memory of each process in the running state in the system are obtained, so as to provide data support for subsequently analyzing the cause of the memory leak. Wherein, the period of traversal can be set according to experience flexibility, such as: the cycle time was 60 minutes.
It should be noted that, when each process in the running state is periodically traversed during the running process of the system and the process identifier and the actually used physical memory of each process in the running state in the system are acquired, if the allocable physical memory space of the system is smaller than the preset space threshold, when it is triggered that the process identifier and the actually used physical memory of each process in the running state in the system need to be acquired, the latest acquisition result in the periodic acquisition results may be used as the acquired process identifier and the actually used physical memory of each process in the running state in the system. Of course, when the allocable physical memory space of the system is smaller than the preset space threshold value and the process identifier of each process in the running state in the system needs to be acquired and the physical memory is actually used, the process identifier can be acquired again, that is, the process identifier is acquired in real time, so that the accuracy is improved.
In specific implementation, when the process identifier of each process in the running state in the system is acquired, the process identifier may be directly or indirectly acquired from the attribute information of the process. Specifically, when a single attribute information in the process attribute information is used as the process identifier, for example, when a process name or a process identifier is used as the process identifier, the process identifier may be directly obtained from the attribute information of each process; when a combination of a plurality of pieces of attribute information in the process attribute information is used as the process identification, for example, when a combination of a process name and a process identifier is used as the process identification, the process identification may be indirectly acquired from the attribute information of each process.
In specific implementation, when the actually used physical memory of each process in the running state in the system is obtained, one thread or work queue may be started, and the actually used physical memory of each process is obtained through a get _ mm _ rss kernel function. Of course, in other embodiments of the present invention, the data may be obtained in other manners, and the present invention is not limited to the specific limitations.
It should be noted that the pre-configured memory leak level table includes a corresponding relationship among the process identifier, the memory leak threshold, and the memory leak level. The memory leak threshold refers to a threshold value at which a process actually uses a physical memory.
In the memory leakage level table, different processes may configure different memory leakage thresholds because different processes use different physical memories. In order to determine the severity of the process memory leak, one or more memory leak thresholds may be set for each process, where different memory leak thresholds correspond to different memory leak levels.
The correspondence between the memory leakage threshold and the memory leakage level may be set according to an empirical value. For example, if the memory leakage levels are 1 level, 2 levels, and 3 levels in sequence from low to high, the memory leakage level corresponding to the memory leakage threshold of 100M may be set to be 1 level; the memory leakage level corresponding to the 300M memory leakage threshold is 2 levels; the memory leak level corresponding to the memory leak threshold of 500M is level 3.
In specific implementation, the process identifier and the actually used physical memory of each process in the running state in the system are acquired in step 101, so that the memory leakage level of each process in the running state can be determined based on the pre-configured memory leakage level table, the process identifier and the actually used physical memory of each process acquired in step 101.
It should be noted that, if a certain process in the running state does not have the configuration of the memory leak threshold and the memory leak level of the process in the memory leak level table, the process may be determined by using a system default value or may be omitted, which is not limited in the embodiment of the present invention.
In specific implementation, after the memory leakage level of each process is determined in step 102, some or all processes with memory leakage levels greater than the first preset level threshold may be closed to recycle the physical memory of the system. The first preset level threshold may be set according to an empirical value. For example, when the memory leakage level is divided into 1-10 levels from low to high, the first preset level threshold may be set to 8 levels.
In a possible implementation manner, when closing a part or all of the processes whose memory leakage levels are greater than the first preset level threshold, in order to reduce the influence on normal use of the user as much as possible, the running priority of each process in a running state in the system may be obtained, and in the processes whose running priorities are greater than the preset priority threshold, the processes whose memory leakage levels are greater than the first preset level threshold are closed. The preset priority threshold value can be set according to an empirical value.
In specific implementation, if the system is an android system, when closing part or all of the processes with the memory leakage level greater than the first preset level threshold, the system can be combined with a native low memory killer mechanism of the android system, and in the processes with the operation priority higher than the preset priority threshold, the process with the memory leakage level greater than the first preset level threshold is closed.
In another possible implementation manner, when closing a part or all of the processes with the memory leakage level greater than the first preset level threshold, in order to reduce the influence on the normal use of the user as much as possible, according to the amount of the memory space required to be released and the actually used physical memory of each process with the memory leakage level greater than the first preset level threshold, the process with the part or all of the memory leakage level greater than the first preset level threshold may be closed, wherein the sum of the actually used physical memories of all the closed processes is greater than or equal to the amount of the memory space required to be released.
It should be noted that the memory space released by the process that closes each memory leak is the actual used physical memory of the process.
In a possible implementation manner, the memory recovery amount is increased, and a process in which the memory leakage level is greater than a second preset level threshold may be closed under the condition that the system is determined to be in the idle state, where the first preset level threshold is higher than the second preset level threshold.
The system may be determined in various ways when the system is in the idle state, which is not limited in the present invention. For example, when the system screen is in an off state and does not enter a sleep mode, it is determined that the system is in an idle state; for another example, when the system does not receive an operation instruction from the user for a long time, it is determined that the system is in the idle state.
In specific implementation, under the condition that the system is determined to be in the idle state, closing the process of which the memory leakage level is greater than the second preset level threshold, wherein the second preset level threshold may be one of the memory leakage levels, so as to close the process of which the memory leakage level is greater than the second preset level threshold; or may be a value less than the lowest memory leak level to shut down all processes that leak memory.
In practical applications, the memory recovery scheme provided in the embodiment of the present invention can recover the memory space of the system, solve the problem of memory fragmentation of the system to a certain extent, and ensure the healthy operation of the system when closing a process in which part or all of the memory leakage levels are greater than the first preset level threshold.
The following describes the memory recovery method according to the embodiment of the present invention in detail with reference to fig. 2.
As shown in fig. 2, the memory recovery method provided in the embodiment of the present invention may include the following specific steps:
in step 201, a system assignable physical memory space is obtained. The system may allocate a physical memory space, that is, an unused physical memory space in the system.
In step 203, when it is determined that the allocable physical memory space of the system is smaller than the preset space threshold, the process identifier and the actually used physical memory of each process in the running state in the system are obtained.
In specific implementation, the process identifier of each process in the running state in the system and the physical memory are acquired in real time when the physical memory is actually used. If the system periodically acquires the process identifier of each process in the running state and actually uses the physical memory, the system may not acquire the process identifier again but use the acquisition result of the previous cycle.
It should be noted that, because the running priority of the process in the system changes more frequently, the running priority of the process needs to be obtained in real time, that is, the running priority of the process in the running state in the system at the current time is obtained.
In step 206, in the process with the operation priority higher than the preset priority threshold, closing part or all of the processes with the memory leakage level higher than the first preset level threshold. The preset priority threshold and the first preset level threshold can be set according to empirical values.
And step 208, when the system is determined to be in the idle state, closing the process of which the memory leakage level is greater than the second preset level threshold value. Wherein the second preset level threshold is lower than the first preset level threshold.
In practical applications, the second preset level threshold may be one of the memory leakage levels, so as to close a process in which the memory leakage level is greater than the second preset level threshold; or may be a value less than the lowest memory leak level to shut down all processes that leak memory.
