Specific embodiment
It is right in the following with reference to the drawings and specific embodiments in order to keep the purposes, technical schemes and advantages of the application clearer
The application is described in detail.
Memory is one of the ost important components in terminal device, such as PC, in PC all programs be all after being called by CPU
It is run in memory, therefore influence of the performance of memory to terminal device is very big.The mode of any program normal use memory is all
It is that, using being discharged after terminating, if do not discharged, will appear memory overflow using preceding first to file, causes subsequent in this
Depositing can not all be used.Therefore it after multiple program application memories, if these memories are not discharged in time, may lead
It causes memory to exhaust, can not work normally so as to cause terminal device.
The memory being applied inside usual terminal device by memory linked list maintenance, memory chained list is a kind of physical store
Discontinuous on unit, non-sequential storage organization, every section of memory being applied corresponds to a memory node on memory chained list, interior
Depositing the logical order between node is realized by the pointer link orders in chained list.
The type of chained list may include: single-track link table, doubly linked list and circular linked list.Wherein, each of doubly linked list
All there are two pointers in memory node, are respectively directed to the descendant node and predecessor node of the memory node.Therefore from doubly linked list
In any one memory node start, can easily access its predecessor node and descendant node.The application is implemented
Example is described by taking doubly linked list as an example, and the structure of doubly linked list is as shown in Figure 1.
As shown in Figure 1, doubly linked list may include: linked list head, and one or more memory nodes, wherein linked list head packet
Include: Head (head pointer) and Count (function), Head can be directed toward first memory node；Each memory node may include
Memory head and data space；Further, the memory head in the embodiment of the present application may include: position byte space, time word
Save space, pointer space etc..Wherein, position byte space can store: function name, filename, the information such as line number, time byte
Space can store the time that uses of current memory, and pointer space is for storing predecessor pointers prev and heir pointer next, institute
Stating predecessor pointers prev can be used for being directed toward previous memory node, and heir pointer next can be used for being directed toward the latter memory section
Point.The memory of application will be applied using the predecessor pointers prev and heir pointer next in linked list head and memory node
Memory be together in series, constitute memory chained list.
In the embodiment of the present application, the time byte of null of time is used for recording memory due to being assigned in memory head
Between, therefore when traversing memory chained list, the last time can be obtained automatically from the time byte space of each memory node
Memory uses the time, to judge whether the memory node occurs memory overflow using the time according to the memory.With the relevant technologies
In manually write the memory overflow time and compare, due to can be carried out sentencing for memory overflow using the time by automatically recording memory

It referring to fig. 2, is one embodiment flow chart of the detection method of the application memory overflow, which may include
Following steps:
Step 201, when reaching detection cycle, memory chained list is traversed；
In the present embodiment, memory overflow can be detected according to preset detection cycle, which can be
The detection cycle for a routine being manually set.Such as: by taking detection cycle is 1 minute as an example, then every 1 minute, begin stepping through
Memory chained list.Due to containing continuous memory node in logic on memory chained list, traversal memory chained list will be to memory node
It is detected one by one.
Step 202, it for each current memory node traversed, is obtained from the time byte space of current memory node
Current memory is taken to use the time；
When traversing memory chained list, currently traverse memory node is known as current memory node, in conjunction with aforementioned
Fig. 1 description it is found that due to being assigned with position byte space and time byte space in the memory of each memory node, time
When going through to the current memory node, the current memory nearest one can be obtained from the time byte space of the current memory node
The secondary time used, the time are properly termed as current memory and use the time.
Step 203, determine whether current memory node occurs memory overflow using the time according to current memory.
In an optional implementation, when carrying out memory overflow judgement, current sensing time can be obtained, that is, is worked as
Then preceding system time calculates the time difference that the current memory that gets uses time and the current sensing time, this when
Between difference indicate the duration that is not used by of current memory node.Gained time difference is compared with preset time threshold,
When the time difference is greater than the preset time threshold, determines that memory overflow occurs for the current memory node, will let out
The memory of leakage discharges, and deletes from memory chained list；When the time difference is less than the preset time threshold, institute is determined
It states current memory node and memory overflow does not occur, the memory not leaked is also deleted on traversal chained list, subsequent detection will no longer
The memory being once released before detection.
In an optional example, above-mentioned preset time threshold can according to the actual conditions of memory frequency of use into
The corresponding setting of row.Memory higher for frequency of use time threshold can be arranged less than normal；For frequency of use
Lower memory time threshold can be arranged bigger than normal.Such as: the memory of high-frequency log class, almost every two or three
The time of even several seconds minute just will use once, therefore can set the time threshold of this kind of memory to 3 minutes；It is low
The memory of frequency usage will not all be used every even hour half an hour sometimes, therefore can be by this kind of memory
Time threshold be set as 2 hours.It should be noted that the frequency of use in this example it is higher and it is lower only in contrast,
Exemplifications set out does not limit actual classification and setting.Correspondingly, being different types of according to frequency of use
It, can be with after traverse current memory node and get the time difference of the memory node after memory setting time threshold
Its corresponding time threshold is obtained according to the type of current memory, then compares time difference and time threshold.
By above embodiments as it can be seen that the embodiment is assigned with use in the memory head of memory node that memory chained list is added
The time byte space of time is used in record memory, it, can be with therefore when traversing each memory node on memory chained list
When obtaining the last memory automatically from the time byte space of the memory node using the time, and being used according to the memory
Between judge whether the memory node occurs memory overflow.It is let out due to can be carried out memory using the time by automatically recording memory
The judgement of leakage, therefore reduce developer and manually write the triviality of memory release time operation, while avoiding because of memory
Release time chooses the improper erroneous judgement caused to memory overflow.
It is another embodiment flow chart of the detection method of the application memory overflow, the embodiment is to memory referring to Fig. 3

In the present embodiment, memory head can be on the head of memory node space, can also be in the tail of memory node space
Portion is not limited this present embodiment, as long as adjacent memory node can be associated to one-to-one correspondence.
Step 302, when having memory node by use, the time byte for calling preset macro function to calculate the memory node
The address in space；
If some current memory node on memory chained list is used, pass through current memory node using macro function
The address of the address calculation storage time byte space of position byte space.In conjunction with Fig. 1, specific calculation method can be basis
The address (address of data) of current memory node location byte space, by one section of memory of address offset of its position byte space
The size in space, offset memory space can subtract and work as according to memory node storage time byte space address (address of time)

Step 303, the corresponding current memory of the memory node is used into write time time byte space according to address；
The corresponding current memory of current memory node is used into the time, write-in step is automatically updated by the function of macro function
In the rapid 302 time byte space addresses being calculated.
Step 304, when reaching detection cycle, memory chained list is traversed；
Step 305, it for each current memory node traversed, is obtained from the time byte space of current memory node
Current memory is taken to use the time；
Step 306, determine whether current memory node occurs memory overflow using the time according to current memory；
The step 201 into step 306 and Fig. 2 embodiment of abovementioned steps 304 is consistent to step 203, and details are not described herein.
Step 307, when determining that memory overflow occurs for current memory node, the location information of current memory node is exported.
In an optional implementation, when determining that current memory node leaks, the institute leaked will test out
State the core position information of current memory location information or the current memory node and not making for the current memory node
With duration, developer is fed back to, so that developer quickly determines according to the location information of memory overflow the position of memory overflow
It sets.Wherein, the core position information includes at least following a kind of information: the function name of current memory node memory storage, row

10 divide 00 second when being updated within 00 second 2018 08 month 15 days 15).
Newest by the memory headroom of 70 bytes divides 00 second and current inspection using at the time 2018 08 month 15 days 15 10
20 divide 00 second and are compared when surveying the time 2018 08 month 15 days 15, if the newest difference using time and current sensing time is big
In preset time threshold 5 minutes, then it is assumed that the memory headroom of 70 bytes is leaked, and the memory of leakage is discharged, and from
It is deleted on memory chained list；If newest be less than preset time threshold 5 minutes using the time difference of time and current sensing time,
Think that the memory headroom of 70 bytes does not leak, the memory not leaked is also deleted on traversal chained list, subsequent detection will
The memory being no longer once released before detection.
If it is determined that memory overflow has occurred in the memory headroom of current 70 bytes, then exporting determining for the current memory
