Description
Technical field
The present invention relates to technical field of data processing, particularly a kind of method and device judging version number's size.
Background technology
Version number (version number) is the identification number of version.Each operating system (or the saying of broad sense, each software) Dou Youyige version number.Whether version number can make user understand used operating system is up-to-date version and its function of providing and facility.Each version number mainly can be divided into major version number and time version number's two parts.Such as: DOS4.0, major version number is 4, and secondary version number is 0.Generally, point three: < major version number >.< the version number >.< revision number > of version number's definition completely, as 1.0.0.
Version number's upgrading principle: major version number: functional module has large variation, such as increases multiple module or overall architecture changes.Secondary version number: with key plate originally comparatively speaking, the variation of the just local of the upgrading correspondence of secondary version number.But the variation of this local causes program and former version can not be compatible, or creates destruction to the cooperation relation before this program, or functionally has large improvement or enhancing.Revision number: the variation of local, mainly the function of local functions is improved, or the correction of bug, or the expansion of function.In principle, after first stable release is issued, revision number can regular change, and secondary version number then changes according to situation, and the frequency of major version number change is very low, unless there are large reconstruct or function improvement.
Other release-naming specifications: shown in Figure 1, this software version number is made up of four parts, first 1 is major version number, second 1 is sub-version number, 3rd 1 is stage version number, Part IV is that date version number adds Greek alphabet version number, and general 5 kinds of Greek alphabet version number, is respectively: base, alpha, beta, RC, release.Such as: 1.1.1.051021_beta.
Alpha version: this version represents this software in this stage mainly to realize software function, usually only at software developer's internal communication, generally speaking, the Bug of this version software is more, needs to continue amendment.
Beta version: this version there has been very large improvement relative to α version, eliminates grave error, but there are some defects, needs to eliminate further through repeatedly testing, and the main amendment of this version is to the UI similarly being software.
RC version: this version is quite ripe, substantially there is not the BUG led to errors, very nearly the same with forthcoming formal version.
Release version: this version meaning " final version ", after a series of beta versions of version above, has an official release after all, is finally to pay the version that user uses.This version is sometimes also referred to as standard edition.Generally, Release can not appear on Software Cover with word forms, instead is-symbol (R).
Realizing in process of the present invention, inventor finds that in prior art, at least there are the following problems:
Because each software existing or system all have the naming rule of version number alone, and the length of version number also not identical (such as, above-mentioned version number 4.0,1.0.0, the length difference of the two).By comparing version number, existing method judges that software is the need of renewal, the main method comparing version number judges that whether new version number is identical with old version number, if difference, and update software.But the method is only applicable to the situation that new version number is greater than legacy version number, be suitable for scene limited.And, when the naming rule more complicated of version number or version number's length not identical time, the method for existing judgement version number size accurately can not judge the size of version number.

Fig. 2 is a kind of process flow diagram judging the method for version number's size in the embodiment of the present invention.As shown in Figure 2, S101-S104 is comprised the following steps:
Step S101: obtain first version information and second edition information, first version information comprises the length of every segment data of first version number and first version number, and second edition information comprises the length of every segment data of the second edition number and the second edition number.
Concrete, version number generally comprises multiple part, and every part all includes one piece of data.In the embodiment of the present invention, version number is made up of numeral and point, and such as: 4.2.11, this version number is divided into three segment datas, and namely the length of version number is 3, and this three segment data is respectively " 4 ", " 2 ", " 11 ".
Preferably, shown in Figure 3, obtain first version information and second edition information in step S101, specifically comprise the following steps S201-S203:
Step S201: obtain first version number and the second edition number.
Step S202: according to segmentation mark and the second edition number segmentation mark of first version number, carries out dividing processing to first version number and the second edition number respectively, obtains every segment data of every segment data of first version number and the second edition number.
Concrete, for the version number be made up of numeral and point, such as version number: 4.2.11, point ". " is wherein segmentation mark, namely can split version number, and then determine every segment data according to segmentation mark.
Step S203: according to the quantity of the segmentation mark of first version number and the quantity of the second edition number segmentation mark, determines the length of the length of first version number and the second edition number respectively.
In the embodiment of the present invention, owing to there being segmentation mark between every segment data, and the head of version number and tail are not all provided with segmentation mark, so the length of version number identifies relevant with this segmentation, and the length of version number is add one on the basis of segmentation mark.Concrete, in above-mentioned steps S203:
The length of first version number is that the quantity of the segmentation mark of first version number adds 1;
The length of the second edition number is that the quantity of the segmentation mark of the second edition number adds 1.
Step S102: determine length mark information, and when the length of first version number is not less than the length of the second edition number, length mark information is the first length mark; When the length of first version number is less than the length of the second edition number, length mark information is the second length mark.
In the embodiment of the present invention, length mark information is for identifying the magnitude relationship of Liang Ge version number.Concrete, when the length L1 of first version number is not less than the length L2 of (being namely more than or equal to) second edition number, length mark information is the first length mark S1; When the length L1 of first version number is less than the length L2 of the second edition number, length mark information is the second length mark S2.
Step S103: determine first paragraph data and second segment data, and when length mark information is the first length mark information, first paragraph data are every segment data of first version number, and second segment data are every segment data of the second edition number; When length mark information is the second length mark information, first paragraph data are every segment data of the second edition number, and second segment data are every segment data of first version number.
Concrete, when the length L1 of first version number is more than or equal to the length L2 of the second edition number, first paragraph data D1 is every segment data of first version number, and second segment data D2 is every segment data of the second edition number.When the length L1 of first version number is less than the length L2 of the second edition number, first paragraph data D1 is every segment data of the second edition number, and second segment data D2 is every segment data of first version number.
Such as, first version number is 4.2.11, and the second edition number is 4.3.15 (i.e. L1=L2), and now first paragraph data D1 is " 4 ", " 2 ", " 11 ", and second segment data D2 is " 4 ", " 3 ", " 15 ".If first version number is 4.2, the second edition number is 4.3.15 (i.e. L1 < L2), then first paragraph data D1 is " 4 ", " 3 ", " 15 ", and second segment data D2 is 4 ", " 2 ".
Step S104: determine size identification information, and when first paragraph data are greater than second segment data, size identification information is first little mark; When first paragraph data are less than second segment data, size identification information is second largest little mark.
In step S104, judge the size of the every segment data in the second segment data D2 of every segment data and relevant position in first paragraph data D1 successively, when certain one piece of data in first paragraph data D1 is not identical with the segment data of the relevant position in second segment data D2 (when two segment datas can distinguish size), namely can determine size identification information.Concrete, when first paragraph data D1 is greater than second segment data D2, size identification information is first little mark B1; When first paragraph data D1 is less than second segment data D2, size identification information is second largest little mark B2.
Wherein, respectively first version number can be converted to character string with the second edition number, judge the size of segment data according to the size of character string.
Step S105: when length mark information is the first length mark and size identification information is second largest little mark, or when length mark information is the second length mark and size identification information is first little mark, determine that the second edition number is greater than first version number.
Concrete, when length mark information is the first length mark S1 (namely the length L1 of first version number is not less than the length L2 of the second edition number) and size identification information is second largest little mark during B2 (first paragraph data D1 is less than second segment data D2), the second edition number is greater than first version number.
When length mark information is the second length mark S2 (when namely the length L1 of first version number is less than the length L2 of the second edition number) and size identification information is first little mark B1 (first paragraph data D1 is greater than second segment data D2), the second edition number is greater than first version number.
A kind of method judging version number's size that the embodiment of the present invention provides, in conjunction with the size of length mark information and size identification information judgment version number, the length scale of Liang Ge version number can be determined by length mark information, and then the size of Liang Ge version number can be determined in conjunction with length mark information by size identification information.The determination methods of this version number's size considers version number's this parameter of length, and therefore the method goes for simple or complicated version number's name, accurately can judge the size of complex version number.
In one embodiment, shown in Figure 4, determine in step S104 that size identification information specifically comprises step S301-S303:
Step S301: determine number of comparisons threshold value, number of comparisons threshold value is the hop count of first paragraph data.
Wherein, as mentioned above, the hop count of first paragraph data D1 and length mark information-related.When the length L1 of first version number is more than or equal to the length L2 of the second edition number, first paragraph data D1 is every segment data of first version number; When the length L1 of first version number is less than the length L2 of the second edition number, first paragraph data D1 is every segment data of the second edition number.Therefore, the hop count of first paragraph data is the hop count of the version number of length longer (or equal) in Liang Ge version number.
Step S302: compare first paragraph data piecemeal and whether be greater than second segment data, and the number of times compared piecemeal is not more than number of comparisons threshold value.
Step S303: when there are first paragraph data and being greater than second segment data, stop comparison step piecemeal, and size identification information is first little mark; When there are first paragraph data and being less than second segment data, stop comparison step piecemeal, and size identification information is second largest little mark.
In the embodiment of the present invention, for first version number be 4.2.11, the second edition number for 4.3.15, then first compare the major version number of Liang Ge version number, namely compare the size of " 4 " and " 4 ", compare the size of " 2 " and " 3 " afterwards successively.When the data of a certain section are not identical, then stop comparing, and then determine size identification information.In the embodiment of the present invention, " 2 " in first version number are less than " 3 " in the second edition number, and namely first paragraph data are less than second segment data, and therefore size identification information is second largest little mark B2.
Meanwhile, because the length of first version number and the second edition number is identical, namely the length L1 of first version number is not less than the length L2 of the second edition number, and now length mark information is the first length mark S1.According to step S105, length mark information is the first length mark S1 and size identification information is second largest little mark B2, and second edition 4.3.15 is greater than first version 4.2.11.
