TeamWare
From Wikipedia, the free encyclopedia
Teamware is a registered trademark of Teamware Group Oy.
TeamWare (later Forte TeamWare, then Forte Code Management Software) is a distributed source code revision control system made by Sun Microsystems. Last available as part of the Forte Developer 6 update 2 product line, TeamWare is no longer being offered for sale[1], and is not part of the Sun Studio product.
TeamWare's largest deployment is inside Sun itself, where (bar a few exceptions) it was the only VCS used until recently. TeamWare has been used to manage Sun's largest source trees, including those for the Solaris operating system and the Java system, but those code bases are being moved to newer revision control systems such as Mercurial as part of the process of releasing them to open source communities.
TeamWare features a number of advanced features not found in earlier version control systems like RCS and CVS. In particular it features a sophisticated hierarchy of source repositories, and allows atomic updates of multiple files (features found in later version-control systems like Subversion and Perforce). TeamWare allows distributed development, by copying one repository to another (which can reside on another machine or network). Developers can then commit changes to the local copy of the repository, and finally integrate all changes in the local repository back into the original repository.
TeamWare is implemented as a layer over the older SCCS system, which is used to track changes to individual files. TeamWare works only by a system of files accessed by client programs (interacting without a server) and most distributed users of a repository access it by means of a mounted networked filesystem such as NFS.
During his tenure at Sun, Larry McVoy was the architectural lead on TeamWare. The BitKeeper version control system, also designed by McVoy, shares a number of design concepts with the earlier TeamWare.
