Because existing packing compression method is as zip, tar, capital is by ordinary file, and the file of part other types outside ordinary file writes packaging file together with the attribute of these files, and under some use scenes (application scenarios as described in the technology of the present invention background), the file of some types and the attribute of file are non-essential.Usually these attributes can be obtained by calling system function lstat.The packaging method that the embodiment of the present invention provides leaves necessary file by giving up non-essential file, and when necessary file write packaging file is carried out packing compression, not by the attribute of necessary file write packaging file, the compressibility of file can be improved with this, realize better packing effect.
It should be noted that, necessary file just refers to above-mentioned ordinary file.
Fig. 1 shows the flow process that can improve the packaging method of compressibility according to the embodiment of the present invention.
As shown in Figure 1, the packaging method of raising compressibility that the embodiment of the present invention provides comprises step:
S101, according to packing compression parameters traversal target directory;
S102, in ergodic process, judge file under described target directory or described target directory sub-directory under file when being ordinary file, obtain the data of the file under the data of the file under described target directory and the sub-directory of described target directory;
S103, the data write packaging file of the data of file under the described target directory obtained and file under the sub-directory of described target directory to be compressed.
Wherein, during described data write packaging file by the data of file under the described target directory that obtains and file under the sub-directory of described target directory, the attribute information of file is given up.
Wherein, it is the attribute that calling system function obtains file in described ergodic process, after the attribute padding data structure of described file, value according to the flag of described data structure conforms to a predetermined condition, and judges that the file under the sub-directory of file under described target directory or described target directory is ordinary file.
The method also comprises: when judging to be the sub-directory of described target directory in ergodic process, obtain the data of the sub-directory of described target directory, is compressed by the data of the sub-directory of the described target directory obtained write packaging file; Wherein, the data of described sub-directory comprise the path content data of described sub-directory and the path of described sub-directory, do not comprise the file under sub-directory.
Can find, utilize above-mentioned according to file packing method provided by the invention and device, by the type of the file under the sub-directory that first judges file under described target directory or described target directory in ergodic process, judge be after ordinary file using ordinary file as necessary file, non-generic file is then inessential file, gives up inessential file, is only carried out packing and compressing by necessary file write packaging file, compressing file rate can be improved, solve prior art Problems existing.Further, after judging that ordinary file is as necessary file, give up the data (i.e. non-file content data) of the attribute of necessary file, namely not by these attributes write packaging file, thus improve compressing file rate further.
In order to illustrate in greater detail the packaging method of the raising compressibility that the embodiment of the present invention provides, Fig. 2 shows the detailed process of the packaging method of the raising compressibility according to the embodiment of the present invention.
As shown in Figure 2, the packaging method of the raising compressibility that the embodiment of the present invention provides, comprises the following steps:
Step S201: according to packing compression parameters traversal target directory.
Wherein, compression parameters is that user sets, and the object of setting compression parameters is that the selected catalogue of user is as target directory, and using the home directory of target directory as traversal.
Step S202: traversal target directory.
The embodiment of the present invention uses depth-first search mode to travel through target directory, and depth-first search mode adopts recursive algorithm, such as, A is had under target directory, C two sub-directories, the sequence of A catalogue is more forward than C catalogue, the traversal order of the mode of depth-first search is so used to be, after first having traveled through the file under A catalogue, again using A catalogue as root directory, sub-directory under traversal A catalogue, continue with the file under sub-directory under depth-first traversal A catalogue again, until elements all under having traveled through A catalogue, then start to travel through the element under C catalogue, the mode of same employing depth-first search travels through the element under C catalogue.
The object of traversal target directory is to read the sub-directory in target directory and file, for follow-up packing compression work is prepared.
Step S203: the attribute being obtained file by calling system function lstat, the content read by determined property traversal is sub-directory or file, if be sub-directory, then enters step S204; If be file, then enter step S205.
It should be noted that, directly can judge that belonging to sub-directory still belongs to file according to the attribute of file, and the attribute of file can be obtained by calling system function, such as calling system function lstat.
Not only it should be noted that, the content under target directory only has two kinds, and one is sub-directory, and another kind is the file under target directory, and also may include file under sub-directory, so above-mentioned file comprises the file under target directory but also the file under comprising sub-directory.
Step S204: the path content data reading sub-directory, calculate the path of this sub-directory, the path of this sub-directory calculated and the path content data of the sub-directory read out are write packaging file, then using this sub-directory as target directory, circulation step S202-step S203.
Integer 32768 can be represented because 15 bit are maximum, namely maximumly can preserve integer 32768, and path maximum under (SuSE) Linux OS is 4096 bytes, be equivalent to integer 4096, therefore, the path of the embodiment of the present invention takies 15 bit, enough ensures the path under (SuSE) Linux OS.
In order to one_to_one corresponding catalogue and file when decompressing, needing to mark catalogue and file when packing compression, with a bit, the embodiment of the present invention is represented that path is sub-directory or file, if path is sub-directory, bit is set to 1, if path is file, bit is set to 0.
Therefore, embodiment of the present invention path takies disk space two bytes, totally 16 bit, and it is sub-directory or file that first bit is used for path label, and 15 bit are below used for store path length.
The path content data of acquisition approach will obtain path, such as: the path content data of acquisition is abcd, this path is made up of " a, b, c, d " 4 ascii characters, namely be made up of 4 bytes, so the path in this path is 4, namely " it is integer " 4 " that path accounts for the content of preserving in 15 bit spaces, if this path is a catalogue, so the 1st bit is set to 1; If this path is a file, then first bit is set to 0.
Space shared by path content data is change, the length of concrete change is determined such as by the value of the path taking 15bit above: a path is made up of 100 characters, so this path will occupy 100 bytes, it is integer " 100 " that path accounts for the content of preserving in 15 bit spaces, another path is made up of 20 characters, so this path will occupy 20 bytes, and it is integer " 20 " that path accounts for the content of preserving in 15 bit spaces.
What path was followed below is path content data length, and path content data length is the length of the content under path, the actual length taking disk space of the content namely under path.
Step S205: judge whether file is ordinary file, if be ordinary file, then enters step S206; If be not ordinary file, then give up this file.
The deterministic process of this step: calling system function obtains the attribute of file, after the attribute padding data structure of described file, value according to the flag of described data structure conforms to a predetermined condition, and judges that the file under the sub-directory of file under described target directory or described target directory is ordinary file.Concrete:
Calling system function lstat, import current file path into, function inserts stat structure the attribute information returned, the present invention is by judging whether the position of S_IFREG in stat.st_mode is 1 (i.e. (stat.st_mode & S_IFREG) >0), if so, then represent that current file is ordinary file.It should be noted that, being be 1 to illustrate with value here, also can be that other value correspondences of setting judge it is ordinary file.
It is ordinary file that this step travels through according to the determined property of file the file obtained, if traveling through the file obtained is not ordinary file, classified as other file, in order to improve compressibility under Hybrid framework use scenes, the embodiment of the present invention gives up non-essential file, namely other file, gives up other file and means and do not process for other file, only retain ordinary file to compress, reach more ultimate attainment compressibility with this.
Step S206: interpretation go out be ordinary file after, read the path content data of file and the content of file, the path of calculation document and the content-length of file, the path content data of the path of the file calculated, the content-length of file, the file of reading, the content of file are write packaging file, and for the attribute information of file, as information such as file access authority, owner information, group information, last modification times, then do not write packaging file, the content that need compress can be reduced like this, improve compressibility further.
Wherein, the path computing method of file calculate identical with the path of above-mentioned sub-directory, therefore no longer repeat.
And the content-length of file 4 byte representations, namely disk 4 bytes are taken, maximumly represent integer 4294967295, namely the content-length of file accounts for the content of depositing in the space of 4 bytes is integer " 4294967295 ", and meaning that Single document content is maximum can support 4G.
Such as, running into a file content length in ergodic process is 100 bytes, so the content of these 4 bytes store is exactly integer " 100 ", integer " 100 " in fact just enough stores by 1 byte, but agreement must ensure self-consistentency here, so still use 4 bytes to preserve this length, if a file content just has 4G size, so these 4 bytes also enough store 4G, i.e. " 4294967295 " this integer.
The content-length of file is change, and the length of concrete change determined by the value of the file content length of 4 bytes above, such as:
If a/b/test.txt file contains only " XYZ " 3 characters, then the content-length of this file is 3, and so the content-length of file accounts for the content of depositing in the space of 4 bytes is integer " 3 "; Content immediately following the byte of 3 after file content length is " XYZ ", and namely the content of this file occupies 3 bytes.
If contains only " ABCDEFG " 7 characters in a/b/test.txt file, then the content-length of this file is 7, and so the content-length of file accounts for the content of depositing in the space of 4 bytes is integer " 7 "; Content immediately following the byte of 7 after file content length is " ABCDEFG ", and namely the content of this file occupies 7 bytes.
As can be seen from foregoing, in above-mentioned steps S204 and step S206, do not obtain the attribute of file, not by the attribute of file write packaging file, in some use scenes, as under Hybrid framework, installation kit does not need the attribute of these files, can reach more ultimate attainment compressibility by the attribute giving up file.
Step S207: when having traveled through all catalogues and file, packing compression process terminates, and obtains compressed file.
Due to employing is that traversal compresses the mode of simultaneously carrying out with packing, and therefore, after traversal terminates, packing compression process also can terminate, and obtains the file compressed.
Above-mentioned flow process describe in detail the packaging method of the raising compressibility that the embodiment of the present invention provides, by giving up non-essential file, ordinary file is write packaging file to carry out packing and compressing, to improve compressing file rate, further, also give up the attribute of ordinary file during packing, attribute does not write packaging file to carry out packing and compressing, and can improve compressing file rate further.
