Update Changes in CSV/SVN

Introduction Concurrent Versions System is a revision control system that allows multiple developers to collaborate on software projects, while providing much help in keeping the projects in a consistent state although they may be manipulated by any number of developers at any given time allows a developer or developers to maintain version history of a software project and track changes made to the project over time allows developers to maintain several concurrent versions of a project, while providing help in moving changes among those versions, and preserving consistency of individual versions

Types of Changes Modifying of source code in the working file Adding of file to the repository Removing of file in the repository Edit a source code Rename a file

Why updating changes There is need to work with current version of file in repository before committing to avoid conflicts To make working files reflect what's currently in the repository

Commands To update your copy of a module with any changes from the central repository execute: $ cvs update [filename] $ cvs -q update -dP -q flag means that it goes into quiet mode (as opposed to verbose) T -d flag tells it to grab new directories, -P means "prune", or delete things that have been cvs removed

Update flags Depending on the state of your code and the central repository, various things can happen. For each file that is not in sync with the master repository, a flag is thrown, and an action can be done to that file, or not touched. (no flag) - file is up to date M - locally modified A - locally added U - entire file has been updated P - local file has been patched with changes C - your version conflicts with changes that you haven't grabbed yet in the central repository ? - file has not been added to module R - marked for removal, but not yet committed

Update Sample % cd /web/greentravel-dev % cvs update cvs update: Updating. cvs update: Updating acs cvs update: Updating parameters M parameters/greentravel.ini M tcl/ad-admin.tcl M tcl/ad-user-groups.tcl ? tcl/maratrain-reminder.tcl ? tcl/maratrain-utils.tcl ? tcl/coach-defs.tcl cvs update: Updating templates
