What is version control? Version management allows you to control and monitor changes to files – What changes were made? – Revert to previous versions – When were changes made – What code was present in release version Earliest tools were around 1972 (SCCS) Older tools : RCS, CVS, Microsoft Source Safe, PVCS Current tools : Subversion, Mercurial, Git, Bazaar

SVN It’s popular version control program Free It’s well supported – IDEs : MS Visual Studio, Eclipse, Xcode etc. – Cross Platform : Windows, Linux, Mac OS I will explain SVN by using MS visual studio 2010.

SVN Structure Server (Repository) Server (Repository) Client (e.g. MSVS) Client (e.g. MSVS) Client (e.g. Eclipse) Client (e.g. Eclipse) Client (e.g. XCode) Client (e.g. XCode) … My Server Provided Server

Repository Storing the source file and saving the changed log Each client can access server to read and write source.

VisualSVN Access URL : Host IP or computer name e.g. We can use http protocol or https protocol e.g.

Client To use the MS visual studio upto 2010, the best svn plugin is ankhsvn After setup, Tools->Option->Source control 1 st. Send project from client to server 2 nd. Receive project from server to client

Add solution or project to repository Create new project(solution) Add solution to subversion Add to subversion

Add solution – cont. ‘ + ‘ is ready state. Not saved ‘√‘ source file is saved to server Confirm DLL files or resources is not saved automatically. So I need to upload manually. (using Working copy explorer)

Open from subversion File -> Subversion -> Open from subversion To open we can select types of 3 Lastest version Date Revision

Oepn From Subversion – Cont. Run

View project history We can view history each version

View project history DeletedChanged Inserted

Avoid Conflict Conflict : Multiple users to edit a file To avoid conflict, use Copy -> Modify -> Merge pattern main.c user4 user3 user2 user1

Avoid Conflict – cont. Before Modifying, update project lastest version. Make a complete source(well operating) only upload.

Summary Currently many people use SVN. CVS(Concurrent Version System) -> SVN(Subversion) It’s essential to work in team project. (maybe) This situation, a project when you work on multiple computers is good.
