Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Based on the embodiment in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the application's protection.
The application can be used in numerous general or special purpose calculation element environment or configuration.For example: personal computer, server computer, handheld device or portable set, plate equipment, multi-processor device, comprise distributed computing environment of above any device or equipment etc.
The application can describe in the general context of the computer executable instructions of being carried out by computing machine, for example program module.Usually, program module comprises and carries out particular task or realize routine, program, object, assembly, data structure of particular abstract data type etc.Also can in distributed computing environment, put into practice the application, in these distributed computing environment, be executed the task by the teleprocessing equipment being connected by communication network.In distributed computing environment, program module can be arranged in the local and remote computer-readable storage medium including memory device.
One of main thought of the application can comprise, when computer software starts first, just this computer software each required disk file in start-up and operation process is resolved according to each disk file form of correspondence, and each disk file after resolving is read to the foundation internal storage data queue corresponding with described each disk file in internal memory, described internal storage data queue is saved as with the unique corresponding binary file of described arbitrary computer software and be stored in disk again, wherein key word and disk file data are one to one preserved in internal storage data queue.By above-mentioned pretreatment mode, upper once start this computer software in, just can from disk, load and its unique corresponding binary file, and this binary file is because be each disk file of having resolved, so can directly read and write, and all need to resolve disk file in read-write disk file after no longer needing to start each time computer software.Visible the application is the L2 cache as disk file by binary file, improved the speed of computer software read-write disk file, promote the efficiency of computer software read-write disk file, also solved (the I/O of frequent access disk I/O, Input/Output) and to resolve the problem of data of disk file, reduced the expense of system-computed performance.
With reference to figure 1, show the process flow diagram of the reading/writing method embodiment 1 of a kind of disk file of the application, the present embodiment comprises the read-write process of preprocessing process and disk file, wherein, preprocessing process is step 101~step 103, the read-write process of disk file comprises step 104~step 106, and the present embodiment can comprise the following steps:
Step 101: in the time starting a certain computer software first, described computer software required disk file in start-up and operation process is resolved according to corresponding disk file form.
In the present embodiment, if certain software has been installed on computing machine, so in starting for the first time this computer software, in its start-up course, need the disk file at the data place using to be resolved in advance, and in its follow-up operation process, in the disk file at the data place that can normally move, also can be resolved and could normally be read in advance.Therefore, the read-write equipment of the disk file that the present embodiment builds, when can realizing each computer software and start first, by this computer software object that each required disk file is resolved according to each disk file form of correspondence in this start-up and operation process.The embodiment of the present application is resolved required disk file in startup or operational process a certain computer software, do not represent it is that disk file to all is all resolved, it will be understood by those skilled in the art that can be only to wherein certain/some disk file resolves, or only certain or some data in a certain disk file are resolved, the application does not limit this.
For example, for this instant communication software of Ali Wang Wang, in starting for the first time Ali Wang Wang, having some configuration informations is kept in disk file, the such as attribute data such as the runnable interface of Ali Wang Wang, demonstration size, and in the prosperous operational process of Ali, the information such as the instant messaging record between client also need to be kept in disk file, these disk files just all can be resolved it in this step.
Step 102: the disk file after resolving is read to the foundation internal storage data queue corresponding with described disk file in internal memory.
After in to computer software start-up and operation process, each required disk file is resolved according to each disk file form of correspondence, each disk file after resolving is read in internal memory, to set up the internal storage data queue corresponding with each disk file in internal memory.Wherein, key word and disk file data are one to one preserved in this internal storage data queue, are to preserve key word and disk file data after corresponding parsing with the frame mode of key-value (key word-disk file data).Wherein, key word can be understood as current disk file data and is different from the unique identification of other disk file data, the content that corresponding current disk file data are the required read-writes of computer software, has had keyword, can find corresponding current disk file data.
In the time setting up this internal storage data queue, can be according to a certain particular order to key word-disk file data wherein to sorting, for example, frequency of utilization according to disk file data in current start-up and operation process sorts, be the first place that disk file data high frequency of utilization is placed on to internal storage data queue, and generating key word-disk file data pair according to the size of frequency of utilization successively, the disk file data that frequency of utilization is minimum are placed on the position, end of internal storage data queue.Certainly, those skilled in the art also can be according to demand according to other parameters to the key-value in internal storage data queue to sorting.
Be understandable that, the length of this internal storage data queue also can set in advance, and for example, the preset length of key and value is set to respectively to 4 bytes, and the shared length of a pair of key and value be 8 bytes.But, although the length of key and value can set in advance in internal storage data queue, length scale is adjustable, and those skilled in the art still can independently arrange it according to demand.
Step 103: described internal storage data queue is saved as with the unique corresponding binary file of described computer software and is stored in disk.
After setting up internal storage data queue, saved as again a binary file and be stored in disk, because for any computer software, only can be set up an internal storage data queue, therefore, a computer software is also with regard to a unique corresponding binary file.Concrete, internal storage data queue being saved as with computer software one to one when binary file, can generate binary file according to the length of the key of internal storage data queue and value, be according to the order in internal storage data queue successively using key and value to the content in binary file according to its regular length.
Suppose that key and the right regular length of value in internal storage data queue are 8 bytes, so follow-up in reading internal storage data queue, also read take 8 bytes as unit length, so guarantee can to read each time the data in the disk file that key word is corresponding.Wherein, readability, the ease for use of binary file are lower, because the data structure that the data content of binary file is the internal storage data queue required according to user is write direct, if read binary file so follow-up, do not need to resolve again, can directly binary file be read in to internal memory.
It should be noted that, when again internal storage data queue being saved as to binary file, can choose the key of N (value of N can be used according to computer software how many autonomous settings of disk file, for example first 50) position before internal storage data queue and value to a binary file of direct generation.
Wherein, step 101~step 103 is pre-treatment step, for a computer software, only after its process pre-treatment step of step 101~step 103, just can carry out step 104~the read-write process of the disk file of step 106, but for same computer software, the preprocessing process of step 101~step 103 is carried out once, follow-up can renewal binary file in real time.
Step 104: in the time of follow-up startup current computer software, obtain the current binary file of the unique correspondence of described current computer software from disk.
For the current computer software that generates binary file, when its for the second time or follow-up while starting each time, directly from disk, obtain the binary file of the unique correspondence of this current computer software.
Step 105: described current binary file is loaded in internal memory to generate current internal storage data queue.
Directly the binary file getting in step 104 is loaded be direct copying to internal memory, can generate the current internal storage data queue corresponding with current computer software.Concrete, in internal storage data queue binary file being loaded as in internal memory, can load according to the key of predefined internal storage data queue and the right regular length of value, for example, according to the unit length of 8 bytes using the data in the binary file successively key in internal storage data queue and value couple.It should be noted that, because when generating binary file, according to internal storage data queue in sequence, so now only need to read successively binary file according to key and the right regular length of value, set up internal storage data queue according to the order reading again, will generate the content the same with the internal storage data queue of setting up in preprocessing process.
Step 106: according to described current computer software key word to be read and write, from described current internal storage data queue, read the target disk file data corresponding with described key word, or, target disk file data corresponding described key word is write in described current internal storage data queue.
For a current computer software keyword to be read and write, if read operation, the internal storage data queue that can directly load from step 105, read the target disk file data corresponding with this key word (being value value), if write operation can be write direct target disk file data corresponding this key word in described current internal storage data queue.
In actual applications, shown in figure 2, according to current computer software key word to be read, from described current internal storage data queue, read the target disk file data corresponding with described key word, specifically can comprise:
Step 201: judge in described internal storage data queue whether have the target disk file data corresponding with described key word to be read, if so, enter step 202, if not, enter step 203;
Fig. 2 is the process flow diagram of reading disk file.First judge and in internal storage data queue, whether have the target disk file data corresponding with key word to be read, if existed, the data that had computer software to read in internal storage data queue are described, can perform step 202, and if there is no, the data that in internal storage data queue, computer software need to not read are described, perform step 203~step 206.
Step 202: directly read described target disk file data;
Directly from internal storage data queue, read the target disk file data corresponding with key word, then return to computer software;
Step 203: obtain the target disk file corresponding with described key word;
First obtain the target disk file in disk corresponding with this key word;
Step 204: described target disk file is resolved according to the form of described target disk file;
Because target disk file data not in internal storage data queue, illustrates this target disk file and also resolves, now need to resolve this target disk file according to the form of target disk file;
Step 205: read and resolve the target disk file data that described target disk file obtains;
After target disk document analysis, can read and resolve the target disk file data that target disk file obtains, then be returned to computer software;
Step 206: described key word and target disk file data are added in described internal storage data queue.
Finally also need using key word with resolve the target disk file data that obtains as a key-value to being added in internal storage data queue.When guarantee needs to read this target disk file data more like this, do not need to resolve again this target disk file next time, thereby realize the object of the read or write speed that improves disk file.
Shown in figure 3, according to current computer software key word to be written, target disk file data corresponding described key word is write in described current internal storage data queue, can comprise:
Step 301: judge in described internal storage data queue whether have the target disk file data corresponding with described key word to be written, if so, enter step 302, if not, enter step 303;
Fig. 3 is the process flow diagram that writes disk file.First judge and in internal storage data queue, whether have the target disk file data corresponding with key word to be written, if existed, the data that had computer software to write in internal storage data queue are described, can perform step 302, and if there is no, the data that in internal storage data queue, computer software need to not read are described, perform step 303~step 203.
Step 302: directly upgrade described target disk file data;
Directly upgrade the target disk file data having existed in internal storage data queue, realize the object that data is write to disk file;
Step 303: described key word and corresponding target disk file data are inserted in described internal storage data queue.
Key word is inserted in internal storage data queue with corresponding target disk file data.
Adopt the embodiment of the present application, first disk file is passed through to corresponding analytic method, the internal storage data queue that data in disk file are read to internal memory and set up the frame mode of (key-value), can also adjust according to preset rules the order of internal storage data queue, and internal storage data queue is saved as to the binary file corresponding with computer software, upper while once starting computer software, the data of binary file need to be copied to directly generation internal storage data queue in internal memory, now computer software is in the time that needs are read and write disk file, directly read and write from internal storage data queue by the application, after no longer needing to start each time computer software, all need in read-write disk file, resolve disk file.Visible the application is the L2 cache as disk file by binary file, has improved the speed of computer software read-write disk file, has promoted the efficiency of computer software read-write disk file.
Further, because the data in binary file can generate according to the frequency of utilization of computer software, the disk file that so most computer softwares use can directly read, the very big speed that must accelerate computer software reading disk file.
With reference to figure 4, show the process flow diagram of the reading/writing method embodiment 2 of a kind of disk file of the application, the present embodiment is after preprocessing process, realizes the method that computer software reads disk file, the present embodiment can comprise the following steps:
Step 401: in the time of follow-up startup current computer software, obtain the current binary file of the unique correspondence of described current computer software from disk.
Step 402: described current binary file is loaded in internal memory to generate current internal storage data queue.
The specific implementation of step 401~step 402 can reference example 1, does not repeat them here.
Step 403: judge in described internal storage data queue whether have the target disk file data corresponding with described key word to be read, if so, enter step 404, if not, enter step 405.
In the time that computer software need to read disk file data corresponding to certain key word, can first go to read in internal storage data queue, need first to judge in internal storage data queue, whether have the target disk file data corresponding with described key word to be read.
Step 404: directly read described target disk file data, described key word and target disk file data are moved to the first place of described internal storage data queue.
If had in internal storage data queue, just directly read described target disk file data and return to computer software.
The present embodiment difference from Example 1 is, after reading the target disk file data that key word is corresponding, this key word and target disk file data moved to the first place of internal storage data queue.Carried out the once read operation to this key word and target disk file data because current, the reading times that this key word and target disk file data are described has increased once, therefore, by the first place that moves to internal storage data queue of its correspondence, to facilitate reading next time.
Step 405: obtain the target disk file corresponding with described key word, according to the form of described target disk file, described target disk file is resolved.
If do not had in internal storage data queue, need first to obtain the disk file corresponding to this key word of preserving on disk, then this disk file is carried out to the parsing of corresponding format.
Step 406: read and resolve the target disk file data that described target disk file obtains.
Step 407: the first place that described key word and target disk file data is inserted into described internal storage data queue.
The difference of the present embodiment and embodiment 1 is, resolve after the target disk file data that obtains of described target disk file returns to computer software reading, also this key word and target disk file data are inserted into the first place of described internal storage data queue, to facilitate reading next time.
Step 408: judge whether end position key word and end marker bit corresponding to position disk file data in described internal storage data queue represent that described end position key word and position, end disk file data were updated, if not, enter step 410, if so, enter step 409.
In the present embodiment, key word in internal storage data queue and disk file data are to arranging corresponding marker bit, this marker bit is used for representing that a key word and disk file data are to whether being updated, and whether the renewal here can be understood as the data of storing in disk file consistent with the disk file data in internal storage data queue.For example, by data correspondence establishment internal storage data queue in disk file time, first marker bit correspondence is set to 0, illustrate that the data in internal storage data queue are the data in original disk file, once and follow-up data in internal storage data queue have been upgraded, now because an internal storage data queue of only upgrading, so the data in original disk file are not just synchronously upgraded, therefore,, if when these data need to remove internal storage data queue, just first judge whether to carry out renewal.
Step 409: position, described end disk file Data Update, to original disk file, is entered to step 410.
If the marker bit of the end position disk file data in internal storage data queue is 1, can illustrate that it upgraded, now just first by an end disk file Data Update to original disk file, then it is removed from internal storage data queue.
