3 3 May 25, 2005 CVS & Subversion CVS wordt traditioneel veel ingezet in de open source community en in Java omgevingen. The goal of the Subversion project is to build a version control system that is a compelling replacement for CVS in the open source community. Subversion wordt in grote communities, als Apache, ingezet.

Each revision is assigned a unique natural number.  a revision is a “snapshot” of the repository at a particular moment in time  global revision number “revision 5 of foo.c”, -> “foo.c as it appears in revision 5.”  It's important to note that working copies do not always correspond to any single revision in the repository; they may contain files from several different revisions. commit does not pull so you must perform update  shortcuts: HEAD, BASE, PREV,...

14 14 May 25, 2005 Merge Merging is het fundament van svn Op text-files Meestal geen conflicten Built-in conflict resolution Dus ook goede ondersteuning voor het mergen van een branch met de main 'line' Aangeven welke revisies er gemerged moeten worden

15 15 May 25, 2005 Tagging, Branching en Merging Tag = label (in vss) Branch is een aparte kopie Onderliggend mechanisme van taggen en branchen is hetzelfde Smart copy
