Description
Technical field
The present invention relates to field of computer technology, be specifically related to a kind of method and apparatus for the treatment of program upgrade.
Background technology
For program upgrade, such as application programs such as games, generally there is dual mode:
The one, whole bag upgrading is exactly the All Files combination installation kit with a program version, downloads afterwards execution by the terminal staging program and original version is installed or upgraded.
The 2nd, the difference upgrading, mode is that data file is stored according to certain mode, and form a data listed files, the partial information of these data files is write, the ROMPaq elder generation download data files of terminal is tabulated and is compared with local file, the tabulation of formation difference is downloaded afterwards corresponding data file and is upgraded.
But in practice, prior art can be done redaction one time every a period of time to product, so that new user need not to begin to install from prototype version, then upgrades to one by one latest edition.
Such as, for an initial version installation kit A, its follow-up data file comprises data file A1, data file A2 can carry out difference upgrading and need an independent listing file L1 will be to A in order to guarantee client, and A1, the relevant information of A2 is carried out sequential storage.And in order to make follow-up New Consumers that current up-to-date product can directly be installed, then A+A1+A2 can be made the installation kit B of second edition, and the data file that occurs after this is for the data file B1 of second edition, B2, so in order to guarantee that the client of initial version is installed and the client of the second version all can normally be upgraded, need so the data file of initial version is changed listing file again, and change listing file for the data file of the second version; So by that analogy, if in order to make client begin to install product from initial version, and upgrade to one by one last state, along with the increase of the data of upgrading, its version may get more and more, and the corresponding recruitment of file that is present in the server is more.
For whole bag upgrading, the comparison of coherence of file is good, need not consider version problem, and it is fairly simple to download logic, but for the user, download is larger, and each upgrading all can have more redundant data.
Upgrade for difference, only download variance data, shortcoming is that the file amount is very large, but for afore-mentioned, if for identical product, its version a lot of the time, at first, need to be consistent owing between the file of each version, so rolling up along with version, the corresponding quantity of documents of various version increases, and the conforming logic that causes keeping the various version file also becomes increasingly complex.Secondly, owing to there is the file of various version in the server, cause the catalogue File too much, and for the upgrade request of certain client, its storage of server lookup corresponding to the file of described upgrade request the time, need the file of traversal also very huge, affect server performance.Again, inconvenient for store and management because the corresponding document number is relatively a lot, and it is also large to take storage space.

Carry out MD5 such as the content of each upgrade data section that download is obtained and calculate, with the MD5 value that calculates, the MD5 value of downloading in the listing file data that obtain should data segment storing with preceding step compares.
Step D12 if verification is passed through, then stores described upgrade data section;
If the MD5 value is identical, then verification is passed through, and then stores described upgrade data section.
Step D13 is if the verification failure then notifies client described upgrade data mistake.
If the MD5 value is identical, then verification failure then notifies client described upgrade data mistake, needs again to download etc.
With reference to Fig. 2, the schematic flow sheet that it shows a kind of embodiment of the method two for the treatment of program upgrade of the present invention specifically can comprise:
Step 100, generate an executable file, described executable file is used for: will deposit described executable file data field in for the upgrade data that is used for upgrading of the upgrade data of original installation and follow-up new acquisition, and at specified bytes position or the data segment store list file data in described upgrade data district; Comprising of described listing file data recording: the file feature information of installation data and each upgrade data, and installation data and each upgrade data byte location or the data segment in the data field, stored;
Step 110, the program upgrade download request of reception client;
Client can send program upgrade and download request to server, carries out program upgrade with announcement server for this client and downloads flow process.Concrete program upgrade download request can comprise the identity information of client, such as IP address information etc.
In addition, before this step, also can comprise: server can be according to the update status of current executable file, and the notice client is carried out program upgrade and downloaded.
Upgraded such as the upgrade data of server with executable file, then can notify each client that program is upgraded.
Step 120 from the specified bytes position or data segment of described executable file data field, is extracted first row list file data and is offered client downloads;
In embodiments of the present invention, for installation procedure an executable file can be set, the .exe in executable file such as the windows system wherein, the isostructural file of .dll.Wherein, such as Fig. 3, it shows executable file (is the PE file, the PE file is called as the full name that portable executable is Portable Execute, common EXE, DLL, OCX, SYS, COM are the PE files) disk file organization, executable file comprises DOS file header, PE head, Sections table, code segment, reorientation data segment and data field (being each data segment).At the place that begins of a PE file, we can see a DOS file header, and it makes any PE file all is an effective MS-DOS executable file.File header (pressing the COFF form) afterwards, be used for illustrating which kind of machine will be this binary file will operate on, the time of minute several sections, link, be executable file or DLL, etc., the back comprises Section table, i.e. " data directory " array; These catalogues comprise the pointer of each " section " data of many sensings.Be exactly data segment afterwards, the content in each joint is only you and carries out a real requirement of program, the installation logic of code segment and reorientation data segment storage products, and assigned address has been stored the listing file data in the data field, and has stored upgrade data.Comprising of described listing file data recording content: be stored in the file feature information that respectively is suitable for the upgrade data of upgrading in the data field of described executable file, described file feature information comprises the file feature information of each upgrade data and byte location or the data segment of relative executable file.
In executable file, all there is the skew byte in the starting position of the relative executable file of each data segment, which skew byte of can making an appointment so begins the store list file data, and the information such as file feature information, skew byte that comprise that are about to the upgrade data that is suitable for upgrading are stored in this byte that specifies Offsets.The server and client side can specify the listing file data that read this byte that specifies Offsets to process when upgrading flow process so.
Preferably, the file feature information of each upgrade data in the described listing file is successively used journal by upgrading; Described upgrade data successively uses sequential storage by upgrading in described executable file.
Successively use the order of upgrade data during namely according to installation, upgrade data is pressed this sequential storage in the data field, use in order upgrade data a1, a2, a3 during such as installation, so can be forward in the data segment skew byte of data area stores a1, the data segment of storage a2 is right after behind a1, and the data segment of storage a3 is right after behind a2.
So in this step, after server receives the program upgrade download request of client, according to this program upgrade download request for executable file, at first the byte location of appointment or data segment extract the listing file data from the executable file data field, offer client downloads.In the specific data district, relatively the skew byte of executable file starting position be m1 to deviation post be data segment between the m2 position, extract the byte stream of this position data section, provide it to client downloads.Wherein, such as Fig. 3, the deviation post of executable file starting position is 0.
Step 130 receives the upgrade data download request that client sends; Described upgrade data download request comprises: extract local secondary series list file data by client, and with the file feature information of secondary series list file data and first row list file data relatively after, byte location or data segment that the upgrade data that the client of acquisition is not downloaded is stored in described executable file data field;
After client arrives described listing file data, client can compare the file feature information of the file feature information in the listing file data with local this program, judge whether whether file feature information in the listing file data of current download exists the file feature information of each upgrade data section that this locality do not have, need upgrading with the program that judges whether client.If exist, extract so byte location or the data segment of the relative executable file of described upgrade data section, such as the skew byte of relative executable file starting position, then generate the upgrade data download request according to this byte location or data segment.
Concrete, the byte location in the described executable file or data segment are compared described listing file data and local listing file data by client and comprise:
Steps A 11, client is resolved the file feature information of each upgrade data in the listing file data of downloading, and compare with the file feature information of each upgrade data in the client terminal local listing file data, judge whether to occur new file feature information;
Client will be saved to from the byte stream that server is downloaded the listing file data that obtain the corresponding local table data file, then resolve the file feature information of each upgrade data that records in this listing file, such as file feature information, the information such as byte location or data segment.
In the present invention, client is the file feature information in the listing file data of current download, compares with file feature information in the local listing file data, and whether judge in the listing file data of current download has new file feature information to occur.
Steps A 12 if new file feature information do not occur, can judge that then download finishes;
If the new file feature information of outlet not, client can the determining program current version be latest edition so, and then downloading process finishes, not regeneration and send the upgrade data download request.
Steps A 13 if there is new file feature information, is then extracted described new corresponding byte location or the data segment of file feature information, and is generated described upgrade data download request based on described byte location or data segment.
If the file feature information that outlet is new, byte location in the executable file data field or the data segment of the upgrade data section that then the extraction document characteristic information is corresponding, such as the skew byte of relative executable file starting position, then generate the upgrade data download request based on this byte location or data segment.
Further, the file feature information of each upgrade data in described listing file is successively used journal by upgrading; Described upgrade data successively uses on the basis of sequential storage by upgrading in described executable file, and the byte location in the described executable file or data segment are compared described listing file data and local listing file data by client and comprise:

Step B12 if new file feature information do not occur, can judge that then download finishes.
Step B13 if there is new file feature information, then stops comparison, and extracts described byte location or the data segment of described new upgrade data, and generates described upgrade data download request based on described byte location or data segment.
When new upgrade data section occurring, namely during new file feature information, then the residue file feature information in the table data of current download is no longer compared, saving resource consumes.Then generate upgrade request based on current new corresponding byte location or the data segment of file feature information.
Step 140, is extracted upgrade data and institute's upgrade data is offered client downloads at the byte location of storing in the data field or data segment according to the described upgrade data of listing file data recording from described executable file data field.
Pointed out because of the upgrade data download request and to have extracted data from which position of executable file and offer client downloads to upgrade, server can according to each position of this prompting, extract data and offer client downloads from executable file so.
Optionally, the file feature information of each upgrade data in the previous list file is successively used journal by upgrading; Described upgrade data successively uses sequential storage and step B11 to the basis of step B13 by upgrading in described executable file, described according to described upgrade data download request, extract upgrade data from described byte location or the data segment of executable file, offer client downloads and comprise:
Step C11, according to described upgrade data download request, the byte stream that begins to extract upgrade data from the described byte location of executable file or data segment sends to client;
Owing to use the upgrade data of sequential storage during executable file by upgrading, and in the upgrade data request that step B13 generates, only pointed out the relative executable file skew byte that the starting position begins to download, this step can be from the skew byte of this prompting so, the data that exist after it are extracted entirely offer client downloads, thereby can not make mistakes, also only need judge beginning deviation post and final end position because of server, and it goes without doing other extra position judgment, thereby judgement and the download efficiency of server have been improved.
In addition, in described table data file, also can comprise the file size (be 500 bytes such as size) of upgrade data section, further, comprise during described client:
Described client is stored as the byte stream that receives the local upgrade data file of corresponding upgrade data section one by one according to the file size of each upgrade data section.
Beginning to extract data to client downloads such as server from executable file skew byte 1000 byte locations, is 500 bytes and begin first file a1 size from this position, and second file a2 is 800 bytes, and the 3rd file a3 is 300 bytes.
Server is offset 1000 bytes from executable file and extracts data to client so, client judges that the total amount of byte that receives was by 500 o'clock, then this section byte stream is saved as a1, the byte stream that receives adds up at 1300 o'clock, then the byte stream between the 800-1300 is saved as a2, the byte stream that receives adds up at 1600 o'clock, then the byte stream between the 1300-1600 is saved as a3.
The check information that wherein, also can comprise the upgrade data section in the described listing file data in the file feature information of each upgrade data;
Calculate the MD5 value such as the data content of upgrade data section being MD5 (MD5, message digest algorithm the 5th edition), correspondence is stored.
Further comprise:
Step D11 behind the complete described upgrade data of described client downloads, calculates the check information of described upgrade data, and the check information of this upgrade data in described check information and the listing file data is compared;
Carry out MD5 such as the content of each upgrade data section that download is obtained and calculate, with the MD5 value that calculates, the MD5 value of downloading in the listing file data that obtain should data segment storing with preceding step compares.
Step D12 if verification is passed through, then stores described upgrade data section;
If the MD5 value is identical, then verification is passed through, and then stores described upgrade data section.
Step D13 is if the verification failure then notifies client described upgrade data mistake.
If the MD5 value is identical, then verification failure then notifies client described upgrade data mistake, needs again to download etc.
So client then can be upgraded based on the new upgrade data file that download obtains according to logic is installed.
