This is a continuation-in-part application of U.S. patent application Ser. No. 09/177,443, filed on Oct. 21, 1998, U.S. Pat. No. 6,195,796 entitled “User Centric Source Control”.
1. Field of the Invention
The present invention relates to the field of computer systems. More specifically, the present invention relates to methods and apparatuses associated with the distribution of program products for computer systems.
2. Background Information
Program products are typically distributed in a vendor centric manner as illustrated in FIG. 1. Code control system is employed to provide versioning control to source files associated with program products on the vendors' system or systems. Only the “release” version of a program product source file is converted into object or executable form for distribution to the users, and the conversion process is performed on the vendors' systems. Examples of these vendor centric code control systems include those disclosed in U.S. Pat. Nos. 4,558,413, 4,912,637, 5,357,631 and 5,495,610.
Under this conventional vendor centric approach to source control and distribution, each program product group or software vendor goes about its development, conversion and distribution with little regard to other program product groups or software vendors, except perhaps performing certain amount of system level testing with a small group of selected program products. As a result, it is not unusual for a user, upon installing a number of program products, to find that the program products are incompatible and may not operate together, or upon applying a fix to one program product, other previously functioning program products or the entire system would fail. Once finding himself/herself in such a predicament, there are few choices available to the user, and furthermore, there are limited tools available for the user to deal with the problems. Often times, the remedial action requires distribution of an entire replacement version, as opposed to merely the “broken” or “offending” parts.
Additionally, the prior art vendor centric approach to source control is also restrictive in fostering program product interoperability. For example, a vendor of a program product requiring minor extension support from another program product of a different vendor would nevertheless require support and close cooperation from the other vendor. As a further example, users of the same program product are often frustrated in their cooperation by virtue of the fact that they operate with different version levels of the vendor's program product.
These problems or disadvantages are especially undesirable in view of the opportunities to offer the ever increasing population of potential users (which are typically novice), an ever increasing array of functionally rich consumer program products for installation and use on their ever more powerful personal computer systems. Thus, an improved approach to software distribution, including a complementary code control system, is desired.
A user centric approach to program product distribution, including a complementary multi-vendor code control system (MVCCS) suitable for use on a user computer system or its proxy to practice the user centric distribution approach is disclosed. Under the user centric approach, versioning control information of various program products to be installed on various user computer systems are maintained on a user computer system by user computer system basis. Each user computer system and/or its proxy is provided with a portion or the entire MVCCS to facilitate receipt and storage into a common repository for the user computer system versioning control information of different source/object files of different software vendors, and to facilitate retrieval of selective versions of the different source/object files for the user computer system using versioning control information stored in the common repository for the user computer system.
In one embodiment, the MVCCS is further equipped to facilitate receipt and storage into a common library, the different source/object files. In one embodiment, the different source/object files are identified by corresponding universally unique identifiers (UUID), and the versioning control information includes predecessor UUID information. In one embodiment, the common repository is disposed on the user computer system. In one embodiment, the common library is also disposed on the user computer system.
The present invention will be described by way of exemplary embodiments, but not limitations, illustrated in the accompanying drawings in which like references denote similar elements, and in which:
In the following description, various aspects of the present invention will be described. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some or all aspects of the present invention. For purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the present invention. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. In other instances, well known features are omitted or simplified in order not to obscure the present invention.
Parts of the description will be presented in terms of operations performed by a computer system, using terms such as tables, files, data and the like, consistent with the manner commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. As well understood by those skilled in the art, these quantities take the form of electrical, magnetic, or optical signals capable of being stored, transferred, combined, and otherwise manipulated through mechanical and electrical components of a digital system; and the term digital system include general purpose as well as special purpose data processing machines, systems, and the like, that are standalone, adjunct or embedded.
Various operations will be described as multiple discrete steps performed in turn in a manner that is most helpful in understanding the present invention, however, the order of description should not be construed as to imply that these operations are necessarily order dependent, in particular, the order the steps are presented.

Library 302 is used to store source files 318 of a program product in either a base or a delta form (depending on whether the source file is the root or a subsequent change), as well as object files 319 of the program product. Each base/delta source file 318 is advantageously identified by an universally unique identifier (UUID), that uniquely identifies the base/delta source file not only among the base/delta source files of the program product, but among the source files of all program products of all vendors. The UUID also uniquely identifies the corresponding object file generated from source files inclusive of the particular delta source file. Repository 304 is used to store versioning control information 320 of source and object files 318 and 319. Versioning control information 320 includes in particular predecessor UUID information for each UUID. For the illustrated embodiment, versioning control information 320 also includes cross program product dependency information for the UUIDs, locking information to prevent a corresponding base/delta source file from being further updated, and security/privilege information to prevent unauthorized updates. In alternate embodiments, other control information may also be included in addition to or in lieu of (in part or in whole) the above enumerated control information.
Check-in and check-out functions 306-308 perform their conventional functions of checking in the base/delta source files or selectively checking out different versions of the source and object files, except that check-in and check-out functions 306-308 operate with source and object files that are advantageously identified by the above described UUIDs. Editor 310 performs its conventional function of editing the checked out source files, and compiler/linker 312 performs its conventional function of compiling/linking the checked out/edited compilable source files. Similarly, delta generator 314 performs the conventional function of creating delta source files based on the check-out and modified versions of a source file. Last but not least, distributor 316 performs the conventional function of distributing program products to users, except distributor 316 operates to distribute versioning control information 320, and in some embodiments, base/delta source files 318 and/or object files 319 to MVSCS of the user systems, in accordance with the teachings of the present invention. For the purpose of this application, the term distribution includes packaging of the program products onto distribution medium, such as tapes, diskettes, CDROM, and so forth, for distribution, as well as transferring of the program products to the user systems or their proxies (such as a corporate or publisher server) through a wireless or wired medium, such as a public data network (e.g. the Internet).
Upon generating and assigning the UUID to the base/delta source file, check-in function 306 generates the genealogy for the UUID, i.e. its predecessor ID, and if applicable, dependency and other control information, step 506. The predecessor UUID is determined based on the UUID of the check-out version of the source file, from which the delta source file is generated. For a base source file with no check-out version of the source file, check-in function 306 generates a “null” predecessor UUID. The dependency and other control information are determined based on information stored in associated control files generated by compiler/linker 312. Next, check-in function 306 stores the base/delta source file in library 302, and the predecessor UUID, dependency and other control information (if any) in repository 304, step 508.
At step 602, distributor 316 retrieves the versioning control information of a program product, and distributes them for storage for a user system. As will be described in more details below, the versioning control information are distributed for storage in a common repository of the user system employed to store versioning control information for multiple program products of multiple vendors installed on the user system. In one embodiment, the common repository is operated by a MVCCS serving only the user system. In one embodiment, the common repository is operated by a MVCCS that operates and maintains multiple common repositories for multiple user systems, on a user system by user system basis.
For the illustrated embodiment, distributor 316 also retrieves and distributes other associated control information, step 604. In one embodiment, distributor 316 retrieves and distributes intra as well as cross program product dependency control information. In one embodiment, distributor 316 also distributes locking information that locks down certain base/delta source files to prevent them from further update/modification. In one embodiment, distributor 316 also distributes security/privilege information to prevent unauthorized update/modification to the corresponding base/delta source file.
For the illustrated embodiment, distributor 316 also retrieves the base/delta source files 318 from library 302, and distributes them for storage for the user system, step 606. As will be described in more detail below, in one embodiment, the base/delta source files are also distributed on a user system by user system basis. In other embodiments, the base/delta source files are distributed to server systems (also referred to as proxies of the user systems), each serving a group of user systems, such as a corporate server or a publisher server. In alternate embodiments, object files 319 may also be retrieved and distributed.
While for ease of understanding, the various types of versioning control information distributed by distributor 316 were incrementally described as separate discrete steps, it should be noted that their distribution may be combined in any one of a number of application dependent manners. For example, all the “secondary” versioning control information, i.e. dependency, locking etc., may be combined and distributed together.

Check-in function 706 performs its conventional function of checking base/delta source files 718 and versioning control information 720 into common library 702 and repository 704 as they are received from the vendor. For the purpose of this application, the term “receive” include “receiving” applicable ones of the base/delta source files 718, object files 719 and versioning control information 720 from a distribution medium as well as from a server of a vendor. Check-out function 708 performs its conventional function of selectively retrieving different versions of source files 718 from common library 702, using versioning control information 720 stored in common repository 704, whereas compiler/linker 710 performs its conventional function of compiling/link editing the retrieved compilable source files into object code or executables. [Note that if object files are also distributed, the processing of source files is typically optional.]
In one embodiment, all illustrated elements, i.e. common library 702, common repository 704, check-in and check-out functions 706-708 and compiler/linker 710 are all disposed on the user system where the program products are installed or being installed. In an alternate embodiment, all illustrated elements, except common library 702 are disposed on the user system. Library 702 is either disposed on a “corporate/publisher” server serving multiple user systems, or on the vendor's server, and check-out function 708 retrieves source files 718 or object files 719 from the “corporate/publisher” or vendor server through a private/public network on an as needed basis, using versioning control information 720 stored in common repository 704. Accordingly, check-in function 706 receives only versioning control information 720 from the vendor, and as described earlier, stores them in common repository 704. Generation of the object code/executables, if applicable, are still performed on the user system where the program products are installed or being installed.
In yet another embodiment, only check-out function 708 and compiler/linker 710 are disposed on the user system where the program products are installed. Common repository 720 and check-in function 706 are disposed on a “corporate/publisher” server serving multiple user systems. In other words, the “corporate/publisher” server maintains multiple common repositories, one for each user system, on a one-to-one correspondence basis. Upon receipt of versioning control information 720 of a program product, check-in function 706 stores them into the corresponding common repositories of the user systems where the program product is installed or to be installed. As in the immediately above described embodiment, library 702 is either disposed on the same/another “corporate/publisher” server serving multiple user systems or on the vendor's server. Check-out function 708 retrieves source files 718 or object files 719 from the “corporate/publisher” or vendor server through a private/public network on an as needed basis, using versioning control information 720 stored in the corresponding common repository 704 disposed on the “corporate/publisher” server. Generation of the object code/executables, if applicable, are still performed on the user system where the program products are installed.
In yet another embodiment, none of the illustrated elements are disposed on the user system where the program products are installed. Common repository 720, check-in and check-out functions 706-708, and compiler/linker 710 are disposed on a “corporate/publisher” server serving multiple user systems. As in the immediately above described embodiment, the “corporate/publisher” server maintains multiple common repositories 720, one for each user system, on a one-to-one correspondence basis. Upon receipt of versioning control information 720 of a program product, check-in function 706 stores them into the corresponding common repositories 720 of the user systems where the program product is installed or to be installed. Also similar to the immediately above described embodiment, library 702 is either disposed on the same/another “corporate/publisher” server serving multiple user systems or on the vendor's server. Check-out function 708 retrieves source files 718 or object files 719 from the “corporate/publisher” or vendor server through a private/public on an as needed basis, using versioning control information 720 stored in the corresponding common repository 704 disposed on the “corporate” server. For this embodiment, generation of the object code/executables, if applicable, are performed on the “corporate/publisher” server, and then “downloaded” to the user systems.
To summarize, in each of these embodiments, a common repository 704 is maintained for each user system to store versioning control information 720 of the program products installed or to be installed on the user system. The common repository 704 may be disposed on the user system, or on a “corporate/publisher” server, provided the one-to-one correspondence is maintained. Common library 702 may be complementarily disposed on the user system, the same/another “corporate/publisher” server or the vendor's server, depending on where common repository 704 is disposed. Likewise, check-in and check-out functions 706-708 and compiler/linker 710 are also complementarily disposed, depending on whether common library 702 and common repository 704 are disposed. Note that while in accordance to the teachings of the present invention, one-to-one correspondence to the user system is always maintained for common repository 704, such one-to-one correspondence to the user system is merely preferred but not mandated for common library 702.
In an embodiment, where check-in function 706 also receives source and/or object files of the program products, check-in function 706 handles the receipt and storing of the source and/or object files in like manner as described above for the versioning control information of these source and object files.
The novel user centric approach to program product distribution provides numerous advantages over the prior art vendor centric approach to a user of an user system endowed with the present invention. As an example,
As illustrated in
As illustrated in
Those skilled in the art will appreciate that the above described time based approach to facilitate a user in controlling program product regeneration for his/her system is especially helpful to the user in dealing with system regression caused by the installation of one or more new program products. Through the above described exemplary user interface, the user can easily select an earlier date where the user knows his/her system was operating without the recently encountered problems, and with the click of a control button, the user's system is automatically restored back to a prior known properly operating state, without requiring the user to resolve various intra and/or inter program product dependency problems. Similarly, from one known good operating state, the user can also easily select a later date, and with the click of a control button, the user's system is automatically forwarded to a new state to determine whether the system can operate reliably for the user, again without requiring the user to resolve various intra and/or inter program product dependency problems. In general, the user may cause as many “undos” and/or “redos” to be performed in any order and as often as it is desired. Note that the “undos” and/or “redos” may be performed for other non-reliability related reasons, such as compatibility,
Furthermore, in lieu of or in addition to the above described time based approach to controlling program product regeneration, the present invention may also be practiced in conjunction with an usage characteristic based approach to software customization, as disclosed in copending U.S. patent application Ser. No. 09/176,692, filed Oct. 21, 1998, and entitled “Usage Characteristic Based Software Customization”, which is hereby fully incorporated by reference (except for the reciprocating incorporation). For those embodiments where source files are also provided to the user systems or their proxies, the present invention may also be practiced with some or all of the vendors employing security mechanisms to protect their source files. The security mechanisms may be any one of these techniques known in the art, such as a private/public key approach.
While the present invention has thus far been substantially described in the context of empowering user systems with the ability to managing source files from multiple program product vendors, those skilled in the art will appreciate that the benefits of the present invention are not restricted to only this dimension of relationship between a user system and its vendor. Under the present invention, a vendor of a program product may easily provide to its user systems simple extensions it needs in another program product of a different vendor without requiring close cooperation or support from the other vendor. Similarly, users of a program product of a more recent version level may temporarily enable other peer users of the program product of an earlier version level to facilitate data or file sharing between the users. Thus, it is anticipated that the present invention will also benefit inter-vendor as well as inter-user cooperation, leading to an overall improved interoperability experience for the users.
Lastly, we refer now to
Thus, a novel user centric approach to program product distribution, including a complementary multi-vendor code control system, has been described. While the present invention has been described in terms of the above illustrated embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. The description is thus to be regarded as illustrative instead of restrictive on the present invention.
