Wherein, the data of the subdirectory include the path content data of the subdirectory and the path length of the subdirectory, do not include son
File under catalogue.
It can be found that using the above-mentioned file packing method and device provided according to the present invention, by ergodic process
The type for first judging the file under the subdirectory of the file or the target directory under the target directory is judged to be common text
Using ordinary file as necessary file after part, non-generic file is then inessential file, gives up inessential file, only by necessary text
Part write-in packaging file is packaged and is compressed, and compressing file rate can be improved, solve the problems, such as of the existing technology.Further
, after judging ordinary file as necessary file, give up the data (i.e. non-file content data) of the attribute of necessary file,
Packaging file is not written into these attributes, to further increase compressing file rate.
In order to which the packaging method provided in an embodiment of the present invention for improving compression ratio is described in more detail, Fig. 2 shows bases
The detailed process of the packaging method of the raising compression ratio of the embodiment of the present invention.
As shown in Fig. 2, the packaging method provided in an embodiment of the present invention for improving compression ratio, comprising the following steps:
Step S201: target directory is traversed according to compression parameters are packaged.
Wherein, compression parameters are set by user, and the purpose for setting compression parameters is that user selectes a catalogue conduct
Target directory, and using target directory as the home directory of traversal.
Step S202: traversal target directory.
The embodiment of the present invention traverses target directory using depth-first search mode, and depth-first search mode
Recursive algorithm is used, for example, there are two subdirectories of A, C under target directory, the sequence ratio C catalogue of A catalogue is forward, then using deep
The traversal order for spending the mode of first search is, after first having traversed the file under A catalogue, then using A catalogue as root, traversal
Subdirectory under A catalogue is further continued for the file under subdirectory under depth-first traversal A catalogue, until having traversed institute under A catalogue
Then some elements begin stepping through the element under C catalogue, the member under C catalogue is equally traversed by the way of depth-first search
Element.
The purpose of traversal target directory is to read the subdirectory and file in target directory, for subsequent packing compression work
It prepares.
Step S203: obtaining the attribute of file by calling system function lstat, by determined property traversal reading
Hold and enters step S204 if it is subdirectory for subdirectory or file；If it is file, S205 is entered step.
It should be noted that directly may determine that according to the attribute of file is to belong to subdirectory to still fall within file, and file
Attribute can be obtained by calling system function, such as calling system function lstat.
It should be noted that content under target directory only there are two types of, one is subdirectory, another kind is under target directory
File, and under subdirectory may also include file, so it include file under target directory includes specific item that above-mentioned file is again
File under record.
Step S204: reading the path content data of subdirectory, calculates the path length of the subdirectory, by the calculated specific item
The path content data write-in packaging file of the path length of record and the subdirectory that reads out, then using the subdirectory as target directory,
Circulation step S202- step S203.
Since 15 bit maximums can indicate that integer 32768, that is, maximum can save integer 32768, and Linux is grasped
Making maximum path length under system is 4096 bytes, is equivalent to integer 4096, therefore, the path length of the embodiment of the present invention
15 bit are occupied, guarantee the path length under (SuSE) Linux OS enough.
In order to correspond catalogue and file in decompression, need to mark catalogue and file when being packaged compression
Note indicates that path is that bit is set to if path is subdirectory by subdirectory or file with a bit to the embodiment of the present invention
1, if path is file, bit is set to 0.
Therefore, path length of the embodiment of the present invention occupies two bytes of disk space, and totally 16 bit, first bit are used to
Path label is subdirectory or file, and subsequent 15 bit are used for store path length.
The path content data of to acquisite approachs will obtain path length, such as: the path content data of acquisition is abcd, this path
It is made of, i.e., is made of 4 bytes " a, b, c, d " 4 ascii characters, then the path length in this path is 4, i.e. " path
It is integer " 4 " that length, which accounts for the content saved in 15 spaces bit, if this path is a catalogue, so the 1st bit
It is set to 1；If this path is a file, first bit is set to 0.
Space shared by path content data is variation, and the length that specifically changes is occupied the path length of 15bit by front
Value determines such as: a path is made of 100 characters, then this path will occupy 100 bytes, path length is accounted for
The content saved in 15 spaces bit is integer " 100 ", another path is made of 20 characters, then this path will account for
According to 20 bytes, it is integer " 20 " that path length, which accounts for the content saved in 15 spaces bit,.
Path length followed by be path content data length, path content data length is the length of the content under path, also
It is the practical length for occupying disk space of content under path.
Step S205: judge whether file is ordinary file, if it is ordinary file, enters step S206；If no
For ordinary file, then give up this document.
The deterministic process of the step: calling system function obtains the attribute of file, and the attribute of the file is filled data
It after structure, is conformed to a predetermined condition according to the value of the marker of the data structure, judges the file under the target directory
Or the file under the subdirectory of the target directory is ordinary file.It is specific:
Calling system function lstat is passed to current file path, and the attribute information of return is inserted stat structure by function,
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), such as
Fruit is, then it represents that current file is ordinary file.It should be noted that being for 1 here with value for example, being also possible to set
Other values correspondence judges it is ordinary file.
The step is ordinary file according to the file that the determined property of file traverses, if the text that traversal obtains
Part is not ordinary file, is classified as other files, in order to improve compression ratio under Hybrid framework usage scenario, the present invention
Embodiment gives up non-essential file, that is, other files, and giving up other files means at not for other files
Reason only retains ordinary file and is compressed, reaches more ultimate attainment compression ratio with this.
Step S206: after interpretation is out ordinary file, the path content data of file and the content of file, calculation document are read
Path length and file content-length, by the path length of calculated file, the content-length of file, reading file
Path content data, file content packaging file is written, and for the attribute information of file, such as file access permission, the owner
The information such as information, group information, last modification time are then not written into packaging file, can reduce the content that need to be compressed in this way, into one
Step improves compression ratio.
Wherein, the path length calculation method of file and the path length calculating of above-mentioned subdirectory are identical, therefore are not repeated.
And 4 byte representations of the content-length of file, i.e. occupancy 4 bytes of disk, maximum can indicate integer
4294967295, i.e. it is integer " 4294967295 ", meaning that the content-length of file, which accounts for the content deposited in the spaces of 4 bytes,
Single file content maximum can support 4G.
For example, encountering a file content length in ergodic process is 100 bytes, then this 4 byte storages is interior
Appearance is exactly integer " 100 ", and integer " 100 " is actually just stored with 1 byte enough, but agreement must assure that front and back one here
It causes, so this length still is saved using 4 bytes, if a file content just has 4G size, this 4 bytes
Also 4G, i.e. " 4294967295 " this integer are stored enough.
The content-length of file is variation, and the length specifically changed is taken by the file content length of front 4 byte
Value determined, such as:
If a/b/test.txt file contains only " XYZ " 3 characters, the content-length of this file is 3, then
It is integer " 3 " that the content-length of file, which accounts for the content deposited in the spaces of 4 bytes,；Subsequent 3 immediately following file content length
The content of byte is " XYZ ", i.e. the content of this file occupies 3 bytes.
If containing only " ABCDEFG " 7 characters in a/b/test.txt file, the content-length of this file is
7, then it is integer " 7 " that the content-length of file, which accounts for the content deposited in the spaces of 4 bytes,；Behind file content length
The contents of 7 bytes be " ABCDEFG ", i.e. the content of this file occupies 7 bytes.
It can be seen from above content in above-mentioned steps S204 and step S206, there is no the attributes for obtaining file, do not have
Have and packaging file is written into the attribute of file, in certain usage scenarios, under Hybrid framework, installation kit does not need these
The attribute of file, the attribute by giving up file can reach more ultimate attainment compression ratio.
Step S207: when having traversed all catalogue and file, being packaged compression process terminates, and obtains compressed file.
Due to compressing the mode carried out simultaneously using traversal and packing, after traversal, it is packaged compression stream
Journey can also terminate, and obtain the file compressed.
The packaging method provided in an embodiment of the present invention for improving compression ratio is described in detail in above-mentioned process, non-by giving up
Ordinary file write-in packaging file is packaged and is compressed, to improve compressing file rate, further, beaten by necessary file
Also give up the attribute of ordinary file when packet, attribute is not written into packaging file and is packaged and is compressed, and can be further improved file
