1  Please sit next to your partner.  If you don’t have a partner, please find one now.

2 CS 282

3  Questions from last time?  Anything you would like to know about the assignment?  Notes ◦ You should do all your drawing inside DrawGLScene ◦ The completed framework is online for Mac OSX, Linux, and Windows (once OpenGL is installed in ECC). ◦ In order to compile the framework, you must download OpenGL (XCode, apt-get, website).

4  SVN is a versioning control software.

5  A repository of files with monitored access to keep track of who and what changes were made to files ◦ Version tracking ◦ Collaboration and sharing files ◦ Historical information ◦ Retrieve past versions ◦ Manage branches

7  Let’s create a repository now.  First, have two terminal sessions up. ◦ The first terminal will be used to access your ECC account (i.e. what you used to log onto the lab computer).  Everything accessed here is considered to be on your “local” machine  This is where your “local copy” is ◦ The second terminal will be used to access your CSE account (i.e. a DIFFERENT account completely separate from your ECC account).  Everything accessed here is considered as being “remotely” accessed on a completely different computer than the ECC computer)  This is where your “repository” is

8  CSE 1) Log into the CSE server in terminal ◦ ssh  CSE 2) Create a repository directory in CSE ◦ ~/repositories/  CSE 3) Type in “svnadmin create tutorial” in the repositories directory ◦ This will create a folder in repositories called “tutorial”

9  ECC 1) Create a directory you would like to add repository files to. ◦ Let’s name it “myproject”  ECC 2) Add the following folders in myproject ◦ trunk ◦ branches ◦ tags  ECC 3) Now type in the following from one directory up from myproject ◦ svn import myproject ories/tutorial  NOTE: this is all one command, and should all be typed onto a single line of the terminal before hitting enter  Replace “username” with your CSE username

10  Those directories you just created are now in your repository ◦ Use the import command on your first revision.  ECC 4) Now delete the local directory (myproject) on the ECC side. ◦ rm –fr myproject  ECC 5) Now let’s get the revision stored in the repository. ◦ svn checkout rial  NOTE: this is all one command, and should all be typed onto a single line of the terminal before hitting enter  Replace “username” with your CSE username  Congratulations! You have just successfully created and downloaded your first svn repository!

11

12  First, switch drivers!  ECC 6) Go into tutorial/trunk/ and create a file in it ◦ For example, main.cpp  ECC 7) Commit this to your repository ◦ svn commit –m “[insert meaningful message here]”  ECC 8) Now, use and test the following commands… ◦ Use these commands by typing: svn CommandNameHere  add ◦ Use this when you want to add a file to your repository. ◦ Create a main.h and add it to the repository (don’t commit it yet).

13  delete ◦ Use this when you want to remove a file from the repository ◦ Remove main.cpp (don’t commit yet).  status ◦ Use this to check what you’ve changed so far. ◦ “?” – You haven’t added this file yet  NOTE: This is fine. You don’t ALWAYS have to add files that are denoted with a “?”. NEVER ADD YOUR BINARIES (EXECUTABLES). ◦ “A” – You’ve added this file. ◦ “M” – You’ve made changes to this file.

14  diff ◦ Check out the exact lines of code you’ve added or removed. ◦ “+” means you’ve added this line, ◦ “-” means you’ve removed this line.  update ◦ Allows you to update to the newest revision. ◦ Have your partner svn checkout (co) the repository on their computer. ◦ Commit the changes you’ve been making. ◦ Have your partner svn update. ◦ Call me when you have completed this step.

15  add ◦ add files to your local repository  status ◦ check which files you’ve changed, which files haven’t been added yet  diff ◦ see what’s different between the revision you’re running and the changes you’ve made  delete ◦ remove files from your local repository  commit ◦ commit your changes to the online repository  update ◦ update your local repository with the latest version

16

17  Partner A and Partner B both work on the same file, test1.cpp.  Partner A commits his changes to the repository.  Partner B finishes a little later, and tries to commit.  Uh oh! Partner B has encountered a conflict. ◦ SVN will then prompt you with a variety of options to handle this conflict

18  In order to resolve conflicts, there are a few things you can do… ◦ Tell SVN to ignore your changes ◦ Tell SVN to ignore your partner’s changes ◦ Manually remove whatever is conflicting, and recommit.  The best way, of course, is to not have a conflict in the first place. ◦ Be sure to google SVN, and take a look at the documentary if you’re having trouble resolving conflicts.
