In the following description, for purposes of illustration, in order to provide the complete understanding to one or more embodiment, many details have been set forth.But, clearly, also these embodiments can be realized when there is no these details.In other example, one or more embodiment for convenience of description, known structure and equipment illustrate in block form an.
Below with reference to accompanying drawing, specific embodiments of the invention are described in detail.
Existing buffer memory sweep-out method achieves the function that user initiatively removes buffer memory, but not for user realizes the function automatically removing buffer memory, therefore the present invention proposes a kind of technical scheme of automatic removing browser rs cache, must not be the problem that user removes browser rs cache automatically with solution.In addition, in prior art when terminal user initiatively removes buffer memory, terminal system can delete all cache files successively, the process of deleting is carried out continuously, likely takies system CPU for a long time, and the CPU time that now system assignment browses the thread of webpage to user tails off, when user browses webpage, be easy to cause page card to pause, even cause application program without response, reduce the viewing experience of terminal user.The further improvement project of the present invention, makes, when removing buffer memory, to remove buffer memory, can reduce the time taking CPU, there will not be Caton phenomenon when user browses webpage according to the cache file deletion algorithm improved, improves user and to surf the Net experience.
First, conveniently understand buffer memory sweep-out method hereinafter, the structure of buffer memory is described, in the buffer, a resource comprises a url mark, each resource is a corresponding caching record in cache database, and this caching record have recorded the head response information of resource, such as url, resource size, resource type, expired time, service time last time etc.Each resource corresponds to a cache file on terminal disk, and this cache file stores the actual content of resource, and cache database stores in the terminal.
Fig. 1 shows the flow process of the method for the automatic removing buffer memory according to the embodiment of the present invention.
As shown in Figure 1, the method for the automatic removing buffer memory that the embodiment of the present invention provides, comprising:
Step S101: when browser start-up loading or when moving to the first Preset Time continuously after loading, the caching record in cache database removed by browser, and provides the information removing cache file to background thread; Wherein, described cache file is corresponding with described caching record.
The first Preset Time mentioned in step S101 is preferably and is preset as 12 hours, and namely browser execution was more than 12 hours, automatically removes a buffer memory, also can be preset as At All Other Times.Automatic removing buffer memory is for removing useless buffer memory, and can clear all useless buffer memory, and also can only remove the useless buffer memory of part, buffer memory comprises two parts, and a part is caching record, and another part is cache file corresponding to caching record.
Automatically removing in buffer memory, caching record comprises the resource that arrives useless and the expired resource without ETag and Last_Modified header field in stipulated time section.
The statistics display of being collected by reality, the resource accounting of service time last time in two weeks of buffer memory is more than 98%, namely the resource of buffer memory is all used in two weeks substantially, and untapped resource can not be used substantially again in two weeks, can clean out as waste resources, therefore, be two weeks in the above-mentioned stipulated time section priority discipline mentioned, also may be prescribed as section At All Other Times.
In addition, ETag and Last_Modified is the response header field of HTTP, and some resources have, some resources do not have, for expired resource, if do not have ETag and Last_Modified header field, this expired resource can not be utilized completely again, is regarded waste resources and disposes; If expired resource has ETag and Last_Modified header field, browser can provide conditional request to Website server, if according to Etag or last_modified header field, Website server judges that expired resource is not changed, then Website server can not return new resources to browser, browser can continue the copy utilizing buffer memory, thus saves flow.
The method of the automatic removing buffer memory that the embodiment of the present invention provides can remove buffer memory automatically when browser loads, and browser may be long-term at running background after loading, the resource cannot disposed overdue resources when browser loads in time and not use for a long time, so need to run continuously more than the resource automatically disposing overdue resources during the first Preset Time and do not use for a long time at browser.
Because each resource can be recorded service time last time in caching record, therefore according to judging whether certain resource was used in two weeks service time last time in caching record.
Because each resource also records expired time in caching record, judge that whether resource is expired according to the expired time in caching record, this resource can utilize the copy of buffer memory before expired time, if resource exceedes the expired time of record, the copy of buffer memory can not be utilized, need again from Website server Gains resources.
When the caching record in cache database removed by browser or after removing caching record, background thread provides removes cache file corresponding to caching record.
Wherein, the information removing cache file comprises the information removing residual cache file and the information removing cache file to be deleted, due to the cache file that do not remove when may exist and clear up buffer memory last time or cache file to be deleted, so send the information removing cache file all first can provide the information removing residual cache file at every turn, reoffer the information removing file to be deleted.
Step S102: background thread, according to the information removing cache file, deletes the cache file corresponding with caching record.
Background thread deletes cache file after the information receiving the removing cache file that browser provides, the thread high due to the priority of system is generally used for foregrounding, CPU can be taken in a large number for removing cache file, the online affecting user is experienced, so preferably adopt the low background thread of priority to delete cache file.
Long owing to deleting cache file elapsed time, in order to the online improving user is further experienced, avoid the phenomenon causing user's card of surfing Internet to pause when deleting cache file, before deletion cache file, rename is carried out to the catalogue at cache file place, delete the cache file under rename directory afterwards again, catalogue rename is equivalent to the operation of deleting cache file is put into backstage and slowly carries out, do not affect the foregrounding of high priority thread.
The flow process of existing cache file deletion algorithm is: first, obtain cache file list to be deleted, each cache file is deleted in circulation, after deleting a cache file, judge consuming timely whether be greater than 3 seconds, if so, then abdicate CPU and provide a piece of news to background thread as deleted thread, deletion thread obtains message can be continued to perform deletion action.But abdicate this step of CPU in some situations not play a role, cause this delete procedure meeting last for several seconds even more than 10 seconds, cause application program without response.
For foregoing problems, the present invention proposes a kind of cache file deletion algorithm of optimization, Fig. 2 shows the flow process of cache file deletion algorithm in the method according to the automatic removing buffer memory of the embodiment of the present invention, as shown in Figure 2, the flow process of cache file deletion algorithm in the method for the automatic removing buffer memory of the embodiment of the present invention, comprising:
Step S201: obtain initialization erasing time ratio after cache file list to be deleted.
Cache file list is the list of cache file name to be deleted, such as [file1, file2, file3, file4....], wherein, file1, file2 .... be filename, deleting in the process of each cache file according to cache file list to be deleted circulation, actual is delete each cache file according to cache file name.
The object defining erasing time ratio is that the time making to take when deleting cache file CPU is no more than 20%, and according to the display of actual tests data, if program nothing response in 250 milliseconds, user will feel that card pauses.So erasing time ratio is set to 20% by our definition, represent in units of one second, the time taking CPU is no more than 200 milliseconds.
Step S202: judged whether cache file to be deleted; If had, perform step S203; If no, perform step S206.
Step S203: delete a cache file after initialization time.
The object of initialization time is to record current time, for subsequent step is prepared.
Step S204: calculate the time of deleting this cache file, deleting next cache file according to the time and erasing time of deleting this cache file than calculating needs interlude.
The algorithm of time in counting period is as follows:
Wherein, elapse represents the time of a deletion cache file, remove_ratio represents that the operation of deleting cache file can take the time of CPU (in units of 1000 milliseconds, such as remove_ratio is 200, represent in 1000 milliseconds, the operable CPU time of deleted file is 200 milliseconds), sleep represents that deleting next cache file needs interlude.
Step S205: within interval time, abdicates CPU, after interval time, returns step S202.
After abdicating CPU, CPU can carry out other work, after interval time, rejudge and whether have cache file to be deleted, if had, delete cache file, step S202 to step S205 is the process of a circulation, each cache file is deleted in circulation, and after deletion cache file, recalculate the next cache file of deletion needs interlude, according to deleting next cache file interval time.
Step S206: terminate.
Utilize the cache file deletion algorithm after above-mentioned optimization, make deletion cache file take the time controling of CPU in 20%, the phenomenon producing when user surfs the Net and block and time can be reduced.
Effect after Fig. 3 a and Fig. 3 b respectively illustrates the automatic removing browser rs cache of the embodiment of the present invention and the effect after utilizing cache file deletion algorithm to optimize, as shown in Figure 3 a, dotted line be automatically remove caching function line on data, solid line is data on the line without automatic removing caching function, by without Automatic clearance function and have Data Comparison on the line of Automatic clearance function known, when ensureing that cache hit rate is constant, total cache size drops to below original half.
Fig. 3 b deletes more than 3530 real cache file on same browser, amount to the iowaittime curve (being obtained by vmstat) during 97M, in fig 3b, dotted line is utilizing the CPU of the cache file deletion algorithm after optimizing to wait for the IO deadline, solid line is the CPU wait IO deadline of the cache file deletion algorithm before optimizing, after optimization cache file deletion algorithm, iowaittime curve major part, below 20%, greatly reduces the probability that user's card of surfing Internet pauses.
Above-mentioned steps describes the method for the automatic removing buffer memory of the embodiment of the present invention in detail, achieve the function for user's Automatic clearance buffer memory, and deletion cache file algorithm aspect is improved, solve the problem causing user's card of surfing Internet to pause when deleting cache file, the deletion cache file algorithm of above-mentioned improvement can not only be applied in the method automatically removing buffer memory, can also be applied to and initiatively remove in the method for buffer memory, for the method initiatively removing buffer memory makes improvement, be described in detail to the method initiatively removing buffer memory improved below.
For the method initiatively removing buffer memory, mainly improve from deletion cache file algorithm aspect, Fig. 4 shows the flow process initiatively removing the method for buffer memory of the embodiment of the present invention.As shown in Figure 4, the flow process initiatively removing the method for buffer memory of the embodiment of the present invention, comprising:
Step S401: when browser start-up loading or load after, browser judges whether to receive the order of initiatively removing cache file; If so, step S402 is performed; If not, browser does not obtain all caching record in cache database, certainly can not delete all caching record in cache database and follow-up deletion cache file yet.
The method realization of functions initiatively removing buffer memory is supplied to user eventually through an option, if user clicks this option, then removes browser rs cache, if user's not click option, does not then remove browser rs cache.This option can be embodied as an icon on browser in dedicating user to, also other mode can be embodied as in dedicating user to, in icon mode, when browser loads or after browser load operating a period of time, this icon in user's click browser, then think that browser receives the order of initiatively removing cache file, open the function initiatively removing browser rs cache, start to remove buffer memory.
Step S402: after receiving the order of initiatively removing cache file at browser, removes the caching record in cache database.
With the method automatically removing buffer memory unlike, initiatively removing in the method for buffer memory, browser can dispose caching record all in cache database, caching record comprises two weeks in the past interior resources be, in past two weeks not by the resource be, the expired resource without ETag and Last_Modified header field, the expired resource having ETag and Last_Modified header field, this is a kind of mode of thorough removing buffer memory, removing browser rs cache that can be profound.That is, no matter whether buffer memory is useful, when active reset mode, all can all be eliminated.
Step S403: when removing the caching record in cache database or after removing caching record, browser provides the information removing cache file to background thread.
Wherein, the information removing cache file comprises the information removing residual cache file and the information removing cache file to be deleted, due to the cache file that do not remove when may exist and clear up buffer memory last time or cache file to be deleted, so send the information removing cache file all first can provide the information removing residual cache file at every turn, reoffer the information removing file to be deleted.It should be noted that, in active reset mode, the information removing cache file also just can remove the information of cache file to be deleted.
Step S404: background thread, after the information receiving the removing cache file that browser provides, deletes the cache file be stored on disk according to cache file deletion algorithm.
Because deleting cache file is a process consuming time, so before deletion cache file, by the catalogue rename of cache file place, then deleted the cache file under rename directory by the background thread that priority is not high.The background thread that priority is not high is an independently background thread, and when there being the task of will delete cache file, this thread can slowly perform deletion work on backstage, does not affect the foregrounding of the high thread of priority like this.
Adopt when deleting cache file and automatically remove cache file deletion algorithm identical in the method for browser rs cache file, please refer to step S201 ~ step S206, do not repeating herein.
Above-mentioned flow process describes the method initiatively removing buffer memory that the embodiment of the present invention provides in detail, and card pauses can user to be made to feel when removing browser rs cache by the cache file deletion algorithm optimized.
The above-mentioned method initiatively removing buffer memory is separate method with the automatic method removing buffer memory, in order to solve not for user removes the problem of browser rs cache automatically, the present invention proposes a kind of method of automatic removing buffer memory, realize the function automatically removing browser rs cache, and in order to solve the problem that page card pauses, present invention optimizes cache file deletion algorithm, cache file deletion algorithm after optimizing is applied in the method initiatively removing buffer memory and the method automatically removing buffer memory respectively, improve from two aspects, solve the problem that the page card in user's use procedure pauses.
