Embodiment two
Fig. 2 is the flow chart of the internal memory monitoring method in the embodiment of the present invention two；The present embodiment has advanced optimized memory
Monitoring method, as shown in Fig. 2, the internal memory monitoring method after optimization, mainly includes the following steps:
S210, by hook tool obtain application program operation when memory information.
In the present embodiment, hook tool is HOOK tool, can capture process by HOOK tool or other processes are sent out
Raw event.HOOK tool realizes writing function in embodiments of the present invention, whole in the process of running for records application program
The memory situation at end.
In the present embodiment, deposit inside be allocated and discharge operation when, record memory information.Further, for interior
The operation deposited specifically includes that malloc function, calloc function, realloc function, free or delete function and new function
Deng.The function of memory is simply introduced below.
Malloc function, i.e. memory allocation are dynamic memory distribution functions, continuous for one piece of application
The memory block region of specified size returns to the region of memory address of distribution with void* type.If Memory Allocation success, return refer to
To the pointer of assigned memory, null pointer is otherwise returned.Only one parameter of malloc function, that is, the memory headroom to be distributed
Size.Such as: void*malloc (size_t size).The block address memory that malloc is returned all is 8 multiple, if 64
System, then for 16 multiple.
Calloc function is also dynamic memory distribution function, is for distributing n length in the dynamic area of memory
The continuous space of size, function return to the pointer for being directed toward distribution initial address；If distribution is unsuccessful, null pointer is returned.
There are two parameter, the respectively size of the number of element and each element, the products of the two parameters to seek to for calloc function
The size of the memory headroom of distribution.Such as: void*calloc (size_t n, size_t size).
Realloc function, i.e. reset allocation, dynamic memory Tuning function, realloc function are mainly used for elder generation
Judge whether current pointer there are enough continuous spaces, if so, expanding the address that mem_address is directed toward, and will
Mem_address is returned, if space is inadequate, from the beginning the size allocation space first specified according to newsize arrives legacy data
Tail copies newly assigned region of memory to, then discharges original mem_address meaning region of memory, while returning newly assigned
The first address of region of memory.Otherwise null pointer is returned.
Free or delete function is dynamic memory deallocation function, for discharge malloc function, calloc function and
The memory headroom that realloc function is distributed to pointer variable.The pointer variable has to be directed toward null pointer again after use, prevents
Wild pointer occurs, and effectively evades maloperation.
New is equivalent to a function, after memory has opened up space, returns to the first address in this space.
To above-mentioned malloc function, calloc function, realloc function, free or delete function and new function into
Row HOOK records its distribution or memory address, memory size and memory storehouse of release etc..
S220, memory information is mapped in disk file using EMS memory mappings method.
In the present embodiment, memory mapping, which refers to, is mapped to a file for a memory information, it is preferred that memory mapping
For shared drive, i.e. this page is mapped to the address space of oneself by process A and process B, when process A is accessed in the page for the first time
Data when, it generates the terminal that skips leaf, and kernel reads in this one page to memory at this time and updates page table and be allowed to be directed toward it, with
Afterwards, when process B accesses the same page and page faults occurs, in memory, kernel is only needed the page table of process B the page
Entry is directed toward time page.
Further, in the present embodiment, realize that shared drive, MMAP to pass through mapping between process using MMAP mode
The same ordinary file realizes shared drive.After ordinary file is mapped to the process address space, process can be common as accessing
Memory equally accesses to file, it is not necessary to recall read, the operation such as write.
Fig. 3 is the structural schematic diagram of the memory mapping in the embodiment of the present invention two；As shown in figure 3, in memory headroom by
Multiple virtual memory regions are constituted.Virtual memory region is a homogeneity section in the memory headroom of process, that is, is had same
The continuation address range of characteristic.As shown in figure 3, code data section, primary data section, BSS data segment, heap, stack and memory mapping,
It is all an independent virtual memory region.It and is that the address space of memory mapping services is in the rest between storehouse.
In the present embodiment, realizes that memory maps using MMAP mode, mainly there are 3 steps using MMAP mode, firstly, into
Cheng Qidong mapping process, and one is found that is, in disk space in disk file for mapping creation memory information mapping area
The idle continuous disk address met the requirements of section distributes one _ typedef struct structure for this address, then to this
Each region of a structure is initialized, and newly-built regional structure (typedef_struct) is inserted into disk areas chained list
Or in tree.Secondly, calling function MMAP, the mapping relations one by one of file physical address and process virtual address are realized,
After as mapping is assigned with new disk address region, by memory information pointer to be mapped, in memory information
Corresponding memory information descriptor is found in descriptor table, by memory information descriptor, memory that HOOK tool has obtained
Information calls MMAP function, MMAP function locating is to memory information in memory by the memory information structural body of the memory information
In virtual address, by call function establish page table, that is, realize the mapping relations between memory address and disk areas.Most
Afterwards, process initiates the access to this piece mapping space, and the copy of disk is stored in realization.That is the read or write access time of process
This section of mapping address of disk space finds this sector address not on the page by inquiring page table.Because only establishing at present
Address of cache, real memory information copy in disk not yet, therefore cause page fault.Page fault carries out a system
Column judgement after determining without illegal operation, initiates demand paging process.Then call function that lacked page is encased in disk from main memory
In.
In this in real time example, the implementation of two kinds of MMAP data structures is provided, one is Mmap tree structures, in addition
One is Mmaplist structures.Two kinds of structures are introduced below.
Illustratively, Mmap tree structure:
typedef struct{
BSMMap Splay Tree NodeIndex rootNode；//node position for nodeIndex=
nodePage*pageSize+nodeIndex*nodeSize
BSMMapSplayTreeNodeIndex freeNode；//first free block
}BSMMapSplayTree；
By above-mentioned programming it is found that the physical location of tree interior joint in memory can be carried out by index function,
Index function can return to the value in table or region.Further, the sequence × page for the page that physical location=node is located at
Size+node return value × node size.
Further, current available node is recorded in freeNode, and enabled node can be directed toward one and can be used
Node forms chain list, records data for quickly distributing available node.
Mmap list structure:
typedef struct{
BSMMap ListIndex rootNode；//node position for nodeIndex=nodePage*
pageSize+nodeIndex*nodeSize
BSMMapListIndex freeNode；//first free block
}BSMMapList；
By above-mentioned programming it is found that the physical location of list interior joint in memory can be carried out by index function,
Index function can return to the value in table or region.Further, the sequence × page for the page that physical location=node is located at
Size+node return value × node size.
Further, current available node is recorded in freeNode, and enabled node can be directed toward one and can be used
Node forms chain list, records data for quickly distributing available node.
In the present embodiment, the mapping relations of a kind of virtual memory and disk file are provided, are determined according to mapping relations
Mapping storage structure, in the present embodiment, mapping storage structure use above two MMAP data structure, can select therein
A kind of data store organisation can also be such that two kinds of data store organisations are used cooperatively.
