Description
Technical field
The present invention relates to the Added Management technical field of data processing equipment, particularly relate to software used in a kind of software administration and detection method and system are installed.
Background technology
At present, data processing equipment, as computing machine, smart mobile phone, palm PC, panel computer etc., use more and more universal.The various softwares that data processing equipment runs are also in explosive growth.Require also more and more higher to the Added Management of the hardware and software of data processing equipment.
Wherein for the management of software, current main technical schemes is software manager.Software manager is a kind of software managed the software of data processing equipment.Software manager such as 360 software house keepers, Kingsoft software house keeper etc. that current industry is relatively commonly used.The major function that current software manager possesses comprises: software storage, software upgrading, software unloading, download management etc.
Usually gather the most outstanding conventional software of current industry in software storage in software manager, select installation and upgrade for user.In order to provide abundanter to user, more fully software installation and upgrade, the software supported in current software storage gets more and more, and throughout each classes such as instant messaging, audio and video playing, web page browsing, input methods, sum can reach thousands of even up to ten thousand kinds.360 such as current software house keepers, the quantity supported in software storage is kind more than 11000.Use software manager, the user of data processing equipment can obtain the installation kit of the software in software storage very easily, and carries out edition upgrading, the problems such as the defect in solution legacy version and leak.
In software manager, a basis and the technology of key, the installation being exactly software detects.Whether so-called software installed detection and referred to a certain or various software judged in client computer (i.e. the user data treatment facility of mounting software manager) in mounting software warehouse, if installed, then obtain its version number, the latest edition number of software corresponding to software storage contrasts, and provides upgrade information.For each software supported in software storage, all need to detect client computer and whether install, thus judge that corresponding software is the need of installation and upgrade etc.When the amount of software supported in software storage more and more (as up to ten thousand kinds), how to improve the performance that volume software detects, just seem most important.
At present, in existing software manager, software is installed the main technical schemes detected and is:
Each software in software storage all at least has dbase and version number information, also has corresponding descriptor etc.And be each software distribution software I D(i.e. unique identification of this software in software storage), and provide a software detection policy configuration file, for describing the installation detection method of various software successively.Fig. 1 is the structural drawing of a kind of software detection policy configuration file of prior art.See Fig. 1, wherein " software 1 " and " software 2 " ID that is software, for each software I D, all correspondence is configured with corresponding software detection strategy, as the strategy 1 in figure, strategy 2, strategy 3.Often kind of software detection strategy all describes a kind of concrete inspection policies judging this software (" software 1 " or " software 2 " as in Fig. 1) whether client computer installed in software storage.
When usual a kind of software is installed in the operating system of client computer, except copying except the file needed for this software to the installation directory of client computer, also can do following two kinds of process:
The first process: to the ad-hoc location write key assignments of in registration table.
Such as Windows operating system, described particular location is:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Or
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall
After above-mentioned registry-location write key assignments, can see in window control panel-interpolation delete program list, be illustrated in figure 2 a kind of schematic diagram of Windows operating system control panel-interpolation delete program list.
The second process: to beginning-programs menu and the desktop write shortcut of operating system.Be illustrated in figure 3 the shortcut schematic diagram in the beginning-programs menu of Windows operating system, described shortcut can start the application program that client computer has been installed easily for making user.
Therefore, mainly through detecting these these two positions above-mentioned, can judge whether a certain software is installed to client computer.
Software detection strategy conventional at present, mainly contains following three kinds:
The first software detection strategy: describe the shortcut of a kind of software in the beginning-programs menu and desktop of Client OS, whether having identical shortcut to judge by detection client computer, whether this client computer installs this software, if installed, get the execute file of this software, normally main EXE file or dll file etc., get installed software version number again from this execute file.
The second software detection strategy: describe the registry node information of a kind of software at Client OS, and describe the obtain manner of the installation path of this software, the software installation path of such as Windows operating system can from registration table:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Node or
HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion obtain in DisplayIcon key assignments under Uninstall node or InstallLocation key assignments.
When detecting, detect client computer and whether there is identical registry node information to judge whether this client computer installs this software, if installed, from described key assignments, get the installation path of this software, from installation path, obtain execute file, from this execute file, get installed software version number again.
The third software detection strategy: describe the registry node information of a kind of software at Client OS, and the registration table ad-hoc location directly describing this software version number place.Such as: can from registration table
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Node or
HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion obtain version number in DisplayVersion key assignments under Uninstall node.
During detection, detect client computer and whether there is identical registry node information to judge whether this client computer installs this software, if installed, from described DisplayVersion key assignments, get the version number of this software.
Fig. 4 is that the process flow diagram detected installed by existing software.In prior art, for each software in software storage, carry out order one-time detection according to the relative strategy of each software in the software detection policy configuration file described in Fig. 1.That is:
First whether inspection software 1 is installed at local client computer, specifically according to the software detection strategy of this software 1 shown in Fig. 1, namely strategy 1, strategy 2, strategy 3 detect successively, if detected, then judge that this software 1 is arranged on this client computer, if all do not detected by whole strategy, then judge that this software 1 is not arranged on this client computer.
Secondly, whether inspection software 2 is installed at local client computer, specifically according to the software detection strategy of this software 2 shown in Fig. 1, namely strategy 1, strategy 2, strategy 3 detect successively, if detected, then judge that this software 1 is arranged on this client computer, if all do not detected by whole strategy, then judge that this software 1 is not arranged on this client computer.
Then in like manner order successively inspection software 3,, software N, until software all in software storage all detects complete.
The major defect that detection technique installed by software of the prior art is: when software storage contains large batch of software number, its detection speed slowly, this is because:
1) prior art detects successively to N kind software from the first software in software storage, its overall detection time, can increase with the software number supported and linearly increase.If need the amount of software of detection few, as 100 kinds, total detection time, its speed can also receive generally within 0.1 second; But for the software storage that amount of software is huge, as containing 10,000,20,000 kind of software time, its overall detection time will increase by a year-on-year basis, such as reach 3 seconds, 5 seconds, the refresh rate of software matrix can be had a strong impact on, software matrix display to be upgraded is slow, and the operational efficiency of software manager reduces, and has had a strong impact on Consumer's Experience.
2) in prior art, for each software in software storage, no matter whether this software is installed, all can go to attempt reading registration table and shortcut, judge whether its registry entry and shortcut item exist, and actual majority of case there is no need.Such as the software storage containing 10,000 kinds of softwares, each software has a shortcut item and a registry entry, if software will be carried out to software storage install detection, then need reading 10,000 registration tablies and 10,000 shortcuts, judge whether often kind of software is installed in client computer, namely need registration table and the magnetic disc i/o operation of doing 20,000 times, as everyone knows, magnetic disc i/o operation is more consuming time.And the software number that the machine of in fact general user is installed is no more than hundred kinds.This just causes the redundancy of magnetic disc i/o operation, seriously reduces software and installs the detection speed detected.
Summary of the invention
In view of this, fundamental purpose of the present invention is that the software providing a kind of software manager installs detection method and system, to improve the detection speed of software manager when carrying out software installation and detecting.

Described 6th, 7,8 row show respectively a kind of mapping relations of shortcut information to software I D of software, being wherein the shortcut information of this software after link, is the ID of this software after softid.
After described inspection policies file is issued to the software manager being arranged on client computer, software manager executive software installs the process detected, and namely performs described step 502 and 503.
Concrete, in step 502, software manager needs to perform following steps 521 and/or 522:
Step 521) to enumerate in local client computer operating system the registry node information of mounting software in registration table, generate the list of registry node information.As in Windows operating system, namely enumerate registration table:
HKEY_LOCAL_MACHINE Software Microsoft Windows CurrentVersion Uninstall and
HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion each registry node information under Uninstal, just can obtain the mounting characteristic information of local client computer mounting software.
Fig. 7 is the schematic diagram of the registry node of the mounting software information of Windows operating system.Fig. 7 show only registration table HKEY_LOCAL_MACHINE Software Microsoft Windows CurrentVersion each registry node 702 under Uninstall701, such as, " QQsoftMgr ", " QQWubi ", " QQ spelling input method ", " QQ whirlwind " etc. in figure are the registry node information of corresponding software.These registry node information represent that corresponding software has been arranged on local client computer, in follow-up software is installed and detected, need to detect these mounted softwares and whether belong to software in the software storage of software manager, and the need of upgrading.The concrete mode enumerating these registry node information can the corresponding application programming interface (API, ApplicationProgrammingInterface) that provides of call operation system, such as RegEnumKeyEx.After enumerating, the registry node information that these can be enumerated generates a list, treats follow-uply in inspection policies file, to search information.As for registration table
HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion registry node under Uninsta in like manner, signal of no longer drawing herein.
Step 522) enumerate all shortcuts of beginning-programs menu and desktop in local client computer operating system, generate the list of shortcut information.
Fig. 8 is the shortcut list schematic diagram of mounting software in the beginning-programs menu of Windows operating system.See Fig. 8, the shortcut of each software listed in the list all represents that corresponding software has been arranged on local client computer, and such as shortcut 801 represents that software " WinRAR " has been arranged on local client computer.In follow-up software is installed and detected, need to detect these mounted softwares and whether belong to software in the software storage of software manager, and the need of upgrading.The concrete mode enumerating these shortcut information can the corresponding API that provides of call operation system, such as FindNextFile.After enumerating, the shortcut information that these enumerate can be generated a list, treat follow-uply in inspection policies file, to search information.As for enumerating all shortcut information of desktop in this in like manner, repeat no more herein.
In step 502, when only including registry node information in inspection policies file to the mapping relations of software I D, software manager only can perform above-mentioned steps 521; When only including shortcut information in inspection policies file to the mapping relations of software I D, software manager only can perform above-mentioned steps 522; When including registry node information in inspection policies file to the mapping relations of software I D and shortcut information to the mapping relations of software I D simultaneously, software manager only can perform above-mentioned steps 521 or 522, also can perform step 521 and 522 simultaneously.Due to some software vendor just write registration table and do not increase shortcut information when client software installation, therefore perform step 521 and 522 in this case at the same time, detected result is more comprehensive.
Concrete, in step 503, software manager for step 502 the mounting characteristic information enumerated, in described inspection policies file, search whether there is the mounting characteristic information identical with enumerated mounting characteristic information, if found, then judge that the software represented by software I D corresponding to the mounting characteristic information that finds is installed on local client computer.
For the registry node information of the mounted software of local client computer that step 502 enumerates, software manager is searched in the registry node information in described inspection policies file, look into and see if there is identical registry node information, such as the registry node information " QQ whirlwind " shown in Fig. 7, search successively in inspection policies file in described registry node information and whether have " QQ whirlwind " this registry node information, if had, then judge that the software (this software is the software supported in software manager software storage) represented by the software I D that this registry node information is corresponding is installed on local client computer.
For the shortcut information of the mounted software of local client computer that step 502 enumerates, software manager is searched in the shortcut information in described inspection policies file, look into and see if there is identical shortcut information, for shortcut information that local client computer enumerates " Tengxun's software QQ audio-visual the audio-visual .lnk of QQ ", search successively in described shortcut information in inspection policies file and whether have " Tengxun's software QQ audio-visual the audio-visual .lnk of QQ " this shortcut information, if had, then judge that the software (this software is the software supported in software manager software storage) represented by the software I D that this shortcut information is corresponding is installed on local client computer.
From the above mentioned, the present invention carry out software install detect overall detection time be estimated as:
Overall detection time=enumerate that the machine filled software time+in inspection policies file search the time
Wherein enumerate the machine to have filled software time only to have filled software number with the machine relevant, in inspection policies file, search Time Dependent lookup algorithm.Compared with prior art, registration table of the present invention and magnetic disc i/o access times significantly reduce, have nothing to do with the software number that software manager software storage is supported, only filled software number with local client computer relevant, overall detection time no longer linearly increases with the software number supported.And the time of searching in inspection policies file is also very quick when not utilizing particular algorithm.Therefore, relative to prior art, the present invention can improve the detection speed of software manager when detection installed by software.
In order to improve detection speed further, in a preferred embodiment, can special lookup algorithm be adopted to improve search efficiency during information of searching in inspection policies file, thus improve overall detection speed further.
In order to coordinate lookup algorithm, described when arranging inspection policies file, also need to carry out pre-service to the mounting characteristic information in inspection policies file further.Concrete pretreatment mode can have multiple, and most typical have two kinds:
A kind of is sort to the mounting characteristic information in inspection policies file, adopts dichotomy algorithm to search, that is: to facilitate when follow-up software is installed and detected
Whether follow-up searching in inspection policies file has the mounting characteristic information identical with the mounting characteristic information of enumerated local client computer mounting software, specifically comprises:
For the mounting characteristic information X of each enumerated local client computer mounting software
i, wherein i=1 ..., n, n are the quantity of enumerated mounting characteristic information, and whether adopt dichotomy to search in described inspection policies file has and this mounting characteristic information X
iidentical mounting characteristic information, if found, then judges that the software represented by the software I D that this mounting characteristic information is corresponding is installed on local client computer.
Described binary search is also known as binary search, and advantage is that number of comparisons is few, and seek rate is fast, and average behavior is good.When searching, first by the mounting characteristic information of centre position record in inspection policies file and mounting characteristic information X to be found
irelatively, if both are equal, then search successfully; Otherwise utilize centre position to record and inspection policies file is divided into former and later two sublists, if the mounting characteristic information of centre position record is greater than mounting characteristic information X to be found
i, then search last sublist further, otherwise a sublist after searching further.Repeat above process, until find the mounting characteristic information satisfied condition, make to search successfully, or until sublist does not exist, now search unsuccessful.
Another kind of preprocess method adopts hash algorithm to carry out Hash calculation to each bar mounting characteristic information in inspection policies file to obtain cryptographic hash, and the cryptographic hash of mounting characteristic information corresponding to all software I D in described software storage is comprised further at inspection policies file, hash algorithm is adopted to search to facilitate when follow-up software is installed and detected, that is:
Whether follow-up searching in inspection policies file has the mounting characteristic information identical with the mounting characteristic information of enumerated local client computer mounting software, specifically comprises:
For the mounting characteristic information X of each enumerated local client computer mounting software
i, wherein i=1 ..., n, n are the quantity of enumerated mounting characteristic information, adopt with described inspection policies file is set time the identical hash algorithm that adopts, calculate this mounting characteristic information X
icryptographic hash; Then in described inspection policies file, search whether have the cryptographic hash identical with this cryptographic hash, if so, then search and described mounting characteristic information X in the mounting characteristic information that this cryptographic hash is corresponding from inspection policies file
iidentical mounting characteristic information, if found, then judges that the software represented by the software I D that this mounting characteristic information is corresponding is installed on local client computer.
Adopt above-mentioned pre-service and special lookup algorithm, search efficiency can be improved further, and then improve detection speed.Be such as binary search, then the described time of searching in inspection policies file is log2^n, and wherein n represents the sum of registration table or shortcut in inspection policies file, if HASH to search then efficiency higher.
Certainly, the method for searching, mainly includes but not limited to that above-mentioned binary search and HASH search.In addition other lookup method is also had, such as binary tree search etc.
In another kind of embodiment, method of the present invention can further include after judging that described in step 503 software represented by software I D corresponding to the mounting characteristic information that finds has been installed on local client computer:
The version number of software on local client computer that the mounting characteristic information found described in acquisition is corresponding.After obtaining the version number of this software on local client computer, alignment processing can be carried out according to the strategy of software manager, such as can further include: the latest edition number of software in software manager software storage that the mounting characteristic information found described in acquisition is corresponding, whether the latest edition number judging in described software storage is greater than the corresponding version number on described local client computer, if be greater than, prompting needs to upgrade this software, otherwise points out this software to install.
As for the version number of software on local client computer that the mounting characteristic information found described in how obtaining is corresponding, need the kind seeing mounting characteristic information, the method utilizing registry node information and shortcut information to obtain corresponding version number is not quite similar.If described mounting characteristic information is the registry node information of software in Client OS registration table, then described inspection policies file comprises key name and the execute file name of software installation path corresponding to registry node information further, and/or the software version key name that registry node information is corresponding.
