Embodiment
The embodiment of the present invention provides a kind of file caching method and device, for the file after download, both be stored in level cache, be stored in again in file cache, use when being convenient to file subsequent load, and reduce the buffer memory pressure of level cache and L2 cache, improve the loading velocity of the files such as picture, the situation additionally reducing low memory occurs.
As shown in Figure 1, the file caching method that the embodiment of the present invention provides, comprising:
Step S101, determine to need load document, and when determining to need from this file of web download, carry out file download;
After step S102, download file, downloaded file backup is stored in file cache and level cache.
Because back-up storage while of downloaded file is in file cache and level cache, so again load document time, this file can be searched from level cache, L2 cache, also this file can be searched from file cache, both accelerate the speed of files loading, effectively prevent again the problem of OOM.
Wherein, level cache and L2 cache are generally buffer memory and the internal memory of CPU, and file cache is generally hard disk, or level cache and L2 cache are cpu cache, and file cache is internal memory.
File in the embodiment of the present invention can be picture resource, also can be other file that may repeat to load.
Usually, when determining to need load document, need first to judge whether file stores in the buffer, if so, then directly to load from buffer memory, do not need from this file of web download, so, in step S101, determine to need load document, and determine to need from this file of web download, specifically comprise:
Determine to need load document, and file is not stored in level cache, L2 cache and file cache.
Concrete, when load document, need load document if determine, and when determining that file is stored in level cache, directly load document from level cache, and upgrade the service time of this file;
Load document is needed if determine, and when determining that file is stored in L2 cache, load document from L2 cache, and this file is moved in level cache from L2 cache;
Need load document if determine, and when determining that file is stored in file cache, load document from file cache, upgrades the service time of this file, and is moved in level cache from file cache by this file.
File is being moved to after in level cache, owing to storing new content in level cache, the content that stores in level cache may being caused too much, for preventing the situation of OOM, also comprising:
When the file memory space determining in level cache exceedes the first threshold of setting, the file the longest distance service time last time is moved in L2 cache, until the file memory space in level cache is less than first threshold.
Now, in step S102, downloaded file backup is stored into after in file cache and level cache, owing to all storing new content in level cache and file cache, also the content that stores in level cache and file cache may being caused too much, for preventing the situation of OOM, also comprising:
When the file memory space determining in level cache exceedes the first threshold of setting, the file the longest distance service time last time is moved in L2 cache, until the file memory space in level cache is less than first threshold;
When the file memory space determining in file cache exceedes the Second Threshold of setting, delete the longest file distance service time last time of setting ratio.
Storage space due to file cache is also limited, and its content stored is more, and the speed of file reading is slower, so set Second Threshold, if when the file memory space in file cache exceedes the Second Threshold of setting, then delete a part of file.
In the embodiment of the present invention, file cache refers to internal storage or the SD storer of mobile device, for non-mobile device, also can refer to the memory devices such as hard disk.
When the file in level cache is moved in L2 cache, a class that can be provided by LruCache(Android system, be mainly used in data buffer storage use) by LRU(Least Recently Used, recent minimum use) algorithm realization, namely the file in level cache is stored in LruCache, when the capacity of LruCache is greater than first threshold, by lru algorithm, the file the longest LruCache middle distance service time last time is moved in the second buffer memory.
This first threshold can set according to the actual capacity size of the first buffer memory, also the size of first threshold can be revised according to the ruuning situation of application program each in current system, if other application program operating is less, can suitably increase this first threshold, otherwise, then this first threshold can suitably be reduced.
The capacity of the second buffer memory is usually larger, the file in the second buffer memory can be safeguarded by the file cache management method in device, such as, a class that LinkedHashMap(Android system can be adopted to provide, is mainly used in that data buffer storage uses) mode to be to realize the file management in L2 cache.File adopts that SoftReference(is soft quotes) mode of object stores, and when an object only has soft quoting, if storage space is enough, then by system recoveries, can not can use this object when again loading; If memory space inadequate, then system can reclaim this object.
Management for file cache can realize in the following way: when carrying out file and storing, log file title and current time, when using certain file, upgrade the time that this file is corresponding, during file in deleted file buffer memory, according to the time that each file is corresponding, delete the longest file distance service time last time of setting ratio.
Arranging of Second Threshold can set according to the remaining space of file cache, usually 5M ~ 20M is set to better, such as 10M can be set to, deletion ratio when file memory space exceeds Second Threshold also can be arranged according to actual conditions, usually be set to 30% ~ 50% better, such as, 40% can be set to.
