PVCS

PVCS

PVCS, or Polytron Version Control System, is a software package for revision control of files, in particular source code files.

PVCS follows the "locking" approach to concurrency control; it has no "merge" operator built-in (but does, nonetheless, have a separate merge command). However PVCS can also be configured to support several users simultaneously attempting to edit the file; in this case the second commiter (chronologically speaking) will have a branch created for him/her so that both modifications, instead of conflicting, will appear as parallel histories for the same file. This is unlike CVS and Subversion where the second commiter gets the choice between a "merge" of the two change sets, and the creation of a branch.

Originally published by Polytron in 1985, through a history of acquisitions and mergers, the product was at times owned by Sage Software, Intersolv, and Merant Software. The latter was acquired by Serena Software in 2004, which was itself acquired by Silver Lake Partners in 2006 [ [http://www.serenainternational.com/News/PR/sPR_03102006.asp Serena Press Releases - Serena Software – Application Lifecycle Management - Software Development Life Cycle ] ] .
