First, in order to facilitate understanding of the embodiments of the present invention, some terms or nouns referred to in the present invention will be explained as follows:
JSON (JavaScript Object Notification) is a lightweight data exchange format based on JavaScript language.
Version control tool (Subversion, SVN): the system is an open source code version control system, and compared with RCS and CVS, the SVN adopts a branch management system.
Software Development Kit (SDK): generally refers to the collection of development tools used by some software engineers to build application software for a particular software package, software framework, hardware platform, operating system, etc.
Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method of obtaining difference data, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a flowchart of a method for acquiring difference data according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, obtaining a query request from a client, wherein the query request is used for querying difference data of a target data file from a first version to a second version, and the second version is later than the first version;
step S104, acquiring the difference data from a preset storage area according to the query request;
and step S106, returning the difference data to the client.
Optionally, the query request is used to query difference data of a target data file from a first version to a second version, where the first version is the target data file of the first version (for example, a table file: a planned table file); the second version refers to a second version of the target data file.
The second version is later than the first version, and the first version and the second version can be but are not limited to adjacent versions; for example, if the second version is the latest version, the first version may be a previous version of the latest version; the first version and the second version may have a plurality of versions therebetween, and for example, if the second version is the latest version, the first version may be any version before the latest version.
Optionally, the preset storage area may be a preset database, or a storage area preset in the database.
In an alternative embodiment, the difference data comprises: a first portion and a second portion; the first part includes: a change flag for each data unit in the target data file, a file name corresponding to each data unit, and a version number before and after each data unit is changed, wherein the change flag is used for classifying the target data file according to a change operation type of each data unit; the second part includes: description information corresponding to each data unit.
It should be noted that, in the embodiment of the method for obtaining difference data provided by the present application, in order to avoid storing a large amount of table data and repeatedly calculating the table change content (i.e., difference data) between different tables, in consideration of the fact that the data amount of the difference data of each change of a table file is much smaller than the data amount of the whole table file of two versions, in the embodiment of the present application, the table change viewing platform does not store the table file, but directly performs format processing and storage on the difference data obtained by each calculation of the difference lookup algorithm Diff algorithm, and when different users obtain the difference data through a client and view the difference data, the difference data is directly obtained from the storage database and rendered at the front end, so that the efficiency of obtaining the difference data by the client is improved.
By the embodiment of the application, on the basis of reducing the waiting time of the user, the storage of a large amount of form file data can be effectively reduced, and the repeated calculation of form change contents and the repeated waiting of different users are avoided; moreover, as shown in fig. 2, different planners may submit a plurality of target data files (for example, form files) to the SVN server, and when a user views one or more form files modified by different planners in turn, the user may obtain difference data of a plurality of (more than two) versions and a plurality of files at one time by screening a plurality of versions of form files submitted by the target planners.
In the embodiment of the invention, a query request from a client is obtained, wherein the query request is used for querying difference data of a target data file from a first version to a second version, and the second version is later than the first version; acquiring the difference data from a preset storage area according to the query request; the difference data are returned to the client, so that the purposes of reducing the computing resources occupied by storing the form files and reducing the time for acquiring the difference data are achieved, the technical effect of improving the efficiency of acquiring the difference data by the client is achieved, and the technical problems that the form change checking platform in the prior art is high in computing resources occupied by acquiring the difference data among a plurality of form files and low in acquisition efficiency are solved.
In an optional embodiment, before obtaining the difference data from the preset storage area according to the query request, the method further includes:
step S202, pulling an SVN submission record from an SVN server of a version control tool;
step S204, acquiring the first version and the second version from the SVN server according to the SVN submission record;
step S206, calculating the difference between the first version and the second version to obtain the difference data;
step S208, storing the difference data in the preset storage area.
It should be noted that, because the frequency of submitting records by the SVN in the project development is high, especially for a large project with cooperation of multiple persons, the frequency of the timed pull task for pulling the records submitted by the SVN from the SVN server of the version control tool also needs to be set high correspondingly to meet the requirement that the project group obtains the difference data in real time.
Moreover, since the timing pull task needs to perform a series of time-consuming tasks: the method comprises the steps of pulling an SVN submission record, obtaining a target data file and calculating difference data of the target data file from a first version to a second version, wherein if the timing pulling task frequency for pulling the SVN submission record is set to be too high, the calculation pressure and IO pressure of a version control tool SVN server end are large, and particularly the problems that the time for waiting for SVN server response is long, the data quantity of individual table files is large, the time consumption of Diff algorithm calculation is long and the like can exist in obtaining the target data file.
Therefore, in an alternative embodiment of the present application, as shown in fig. 2, a timed pull task is set at the SVN server to pull the SVN submission record, since the SVN server stores the first version and the second version of the target data file, a Diff algorithm may be used to obtain the first version and the second version from the SVN server according to the SVN submission record, and perform a difference calculation on the first version and the second version to obtain the difference data, and store the difference data in a preset storage area, so that the difference data may be returned to the client when receiving a query request from the client.
In the embodiment of the application, a timing pull task based on a cell distributed task queue is realized at a version control tool SVN server, and the timing pull task is split, for example: and pulling the SVN submitting records from the SVN server every five minutes, and regularly acquiring a target data file, calculating difference data and storing the obtained difference data two minutes after the timing pulling task starts.
Through the embodiment of the application, the requirement for real-time pulling of the SVN submission records is met, and the starting time of the timing pulling task can be staggered, so that the calculation pressure and the IO pressure of the SVN server side in the timing pulling task are effectively balanced.
In an optional embodiment, the difference data is stored in the preset storage area by using a dictionary structure, where the dictionary structure includes: and key value pairs consisting of the change position marks and the values before and after the change.
In order to store the difference data in the database conveniently, the difference data can be processed into a JSON format and stored into a middle character string media field, a dictionary structure is adopted to store the difference data into the database, the difference data and the dictionary format can be conveniently converted with each other, and then the difference data is correspondingly stored or calculated.
Because the excel form file comprises a plurality of sub-tables, and the Diff algorithm reads the sub-table data and calculates the corresponding difference data in sequence, the difference data of the whole form file can be processed into two parts: and the key value pair is composed of a change position mark and values before and after change.
The change position indicator may include: the change marks of all the sub-tables of the table file classify all the sub-table names in the table file into an added list, a modified list, a deleted list and an unchanged list respectively, and simultaneously record the changed file names and the SVN version numbers before and after the change corresponding to the difference data; the numerical value before and after the change is the detailed content of the change according to each sub-table in the list order in the change position mark, and comprises at least one of the following: changing the file name, changing the name of the sub-table, changing all column names of the sub-table, marking each column as addition, modification, deletion or unchanged according to the row and column to which the difference data belongs, recording the changed line data as a dictionary format and classifying the changed line data into a corresponding addition list, modification list or deletion list.
In an alternative embodiment, the dictionary structure is used as a basis for subsequent difference data fusion by storing the change position identifier and the values before and after the change in the dictionary structure according to a fixed key value pair. In addition, since a certain submission of a file may be compared with a plurality of different historical versions, a dictionary structure with the same format as described above is generated by comparing with each historical version, and on the basis, the historical version number of the Diff algorithm comparison may be added as a key, and the dictionary content is used as a value to form a new dictionary structure capable of storing difference data of a plurality of different historical versions.
Taking the above form file as an example of the bonus data table, the file size of the bonus data table is 5.22MB, the storage of the whole bonus data table in the database occupies 2.82MB, the number of submissions of the bonus data table in one week is 19, and if all form files are stored, 53.58MB is needed, but the storage of the difference data of 19 submissions only needs 0.57MB, which is only 1% of the storage space of the existing scheme for storing all form files.
By the embodiment of the application, the technical effect of reducing the resources of the locally stored table data of the SVN server or the table change viewing platform can be achieved, and the purpose of effectively reducing the requirements of the table change viewing platform on the hardware storage condition and performance can be achieved.
In an alternative embodiment, the first version is a previous version adjacent to the second version, and returning the difference data to the client includes: step S1061, directly returning the difference data to the client.
In the above optional embodiment, when the first version is a previous version adjacent to the second version, there is no other version between the first version and the second version, and the difference data between the first version and the second version is uniquely determined, the difference data between the first version and the second version may be directly returned to the client.
In an alternative embodiment, there are multiple versions between the first version and the second version, and returning the difference data to the client includes:
step S1063, performing data fusion processing on the difference subdata between every two adjacent versions between the first version and the second version to obtain the difference data;
step S1065, returning the difference data to the client.
In the above optional embodiment, when there are multiple versions between the first version and the second version, one or more other versions exist between the first version and the second version, and difference data between the first version and the second version is not uniquely determined, the difference sub data between every two adjacent versions between the first version and the second version may be subjected to data fusion processing, and the difference data obtained through the fusion processing may be returned to the client.
In an optional embodiment of the present application, the change information of the form file may include, but is not limited to, change categories and detailed difference data of each sub-form, and after the change information is obtained, the form names of the sub-forms may be rendered into different styles for distinguishing; the embodiment of the application can also display all column names of the sub-table at the front end, perform rendering in different styles according to the change types of the columns, and perform comparative display according to the specific change values of the change rows.
Taking the form file as a prop data form with a large data volume as an example, a user submits a request for acquiring the difference data at the same time, the waiting time of the user is 8.19s from the time the user submits the request to the time the difference data is displayed at the front end, but only 0.21s is needed after the difference data is stored by using a background task and a database, the waiting time of the user can be greatly reduced by the embodiment of the application, and other users only need to wait for 0.21s to check the same difference data, so that the waiting time is shortened by 97%.
By the embodiment of the application, when a user acquires the difference data of the table files of multiple versions, the SVN server side can read the designated table files and the difference data among the table files of multiple versions from the database and perform data fusion processing, render the data fusion result at the front end, and greatly improve the efficiency of acquiring the difference data compared with the multiple Diff algorithm calculation of the files.
In an optional embodiment, performing data fusion processing on the difference sub-data between every two adjacent versions between the first version and the second version to obtain the difference data includes:
step S302, sequencing all versions from the first version to the second version in an ascending order to obtain a sequencing result;
and step S304, sequentially superposing the difference subdata between every two adjacent versions according to the sequencing result to obtain the difference data.
In the embodiment of the present application, the difference data generated by each SVN submission record is organized into a corresponding dictionary format, and when a SVN submission record contains a plurality of versions of form files, only the difference sub-data between every two adjacent versions between the first version and the second version needs to be subjected to data fusion processing, and a new dictionary structure is formed by using the name of the form file as a key and the difference data dictionary of each corresponding form file as a value.
When the client needs to obtain the difference data of the multiple versions of the same table file, the difference data of the multiple versions of the same file can be read by taking the version number of the table file as a key, and the difference subdata between every two adjacent versions between the first version and the second version is subjected to data fusion processing. The logic of the data fusion processing may be to sort all versions included from the first version to the second version in an ascending order to obtain a sorting result, and sequentially superimpose the difference subdata between every two adjacent versions according to the sorting result to obtain the difference data.
Specifically, two added, modified, deleted and unchanged form sheet lists in the difference data dictionary with the same data format are fused to generate a new form sheet classification list, and row values added, modified and deleted in the changed form sheet are subjected to data fusion processing, for example, the same numerical value is added first and then deleted, and then the row values are deleted from the added list. Because the differential data is in a designed format, only lists need to be processed during data fusion processing, compared with the differential data calculated by a Diff algorithm, the efficiency is higher, and cross-version change checking can be really realized, namely, only the differential data among a plurality of specified versions are checked in a form file modified by a plurality of planning personnel in turn.
In an optional embodiment, when a user queries difference data among multiple versions, taking a prop data table submitting versions for three times in succession as an example, if 9.43s of waiting is calculated by a Diff algorithm again, according to the scheme for acquiring difference data provided by the application, the difference data of the multiple versions can be acquired only in 0.54s, so that the waiting time of the user can be greatly shortened, a function of skipping over the difference data modified by a specified version is provided for the user, and the efficiency and the accuracy of acquiring the difference data are improved.
In an optional embodiment, when a user queries difference data among multiple versions, taking a general table combat unit value table as an example, if two planners modify the general table combat unit value table in turn, when the user wants to check the change content of the planners W on the table, a manual scheme needs to check the change content of the multiple versions, and then manually combines the change content of the multiple versions according to the change content of the multiple parts to obtain final difference data, the whole process is subjected to three Diff algorithm calculations and manual calculation processes, and the expected time consumption exceeds 1min; moreover, when the content of the change is large and the change is repeated, the manual comparison is easy to miss or error.
Different from the prior art, by the scheme for acquiring the difference data provided by the embodiment of the application, the accurately merged difference data submitted for multiple times can be checked within 0.57s, and the efficiency of acquiring the difference data can be greatly improved.
