====== Setting Up SVN at ASC ======


Look at the [[http://atlaswww.hep.anl.gov/asc/WebSVN/|WebSVN]] at ANL. Click on the necessary package and download it as a tar file.

To start using SVN at ANL, setup the variable SVNROOT in your .bashrc file as:

<code>export SVNROOT=/users/svn
</code>

No, you can try to get ANL packages. This example shows how to retrieve "HighETjets" package:

<code>svn  co  file:///$SVNROOT/HighETjets/HighETjets/trunk HighETjets</code>

This will copy the trunk into the "HighETjets" directory. Similarly, one can retrive any package shown in [[http://atlaswww.hep.anl.gov/asc/WebSVN/|WebSVN]]

The general rule to retrive a package is the command:

<code>svn  co  file:///$SVNROOT/[Package]/[Package]/trunk  [Package]
</code> where [Package] is your package name.

====== Making updates ======

If you decide to make updates of the package, use the link [[https://twiki.cern.ch/twiki/bin/view/Atlas/SoftwareDevelopmentWorkBookSVN#Looking_at_and_modifying_checked|SoftwareDevelopmentWorkBookSVN]] for more information.

Generally, this is what you should do: cd inside the package (i.e., from where you can see "cmt", "share","src" directories) and type:

<code>svn update
svn  ci  -m  " put here some comment" 
</code>

====== Creating a new SVN package ======


If you setup atlas release, this variable will not be set correctly, so always check "$SVNROOT". Then use svn commands as usual. For example, to put a new package (MyPackage), use this example:

<code>
svnadmin create --fs-type fsfs /users/svn/MyPackage
svn mkdir file:///users/svn/MyPackage/MyPackage
svn import .   file:///users/svn/MyPackage/MyPackaga/trunk -m "Initial import"
</code>

or send email to me (chakanau@hep.anl.gov) to create a new directory in the svn repository. To make the package to be visible on WebSVN, send email to me and I'll synchronize this directory with the web server.

====== SVN setup to access CERN repository ======


Look at the [[https://twiki.cern.ch/twiki/bin/view/Atlas/SoftwareDevelopmentWorkBookSVN|SVN twiki]] As before, run the command: 


<code>kinit   username@CERN.CH</code>



Then you should export this variable:

<code>export SVNROOT=svn+ssh://svn.cern.ch/reps/atlasoff </code>

In order to access a project using SSH authentication, just execute this:

<code>$ svn co svn+ssh://svn.cern.ch/reps/<your_project>
</code>

or if you use a different username for LXPLUS:
<code>$ svn co svn+ssh://<lxplus_username>@svn.cern.ch/reps/<your_project>
</code>

Or you can do this: If your name at CERN different, you should create a file  "config" inside  ".ssh" directory and add:

<code>
  Host svn.cern.ch
  User USER_NAME_AT_CERN
  GSSAPIAuthentication yes
  GSSAPIDelegateCredentials yes
  Protocol 2
  ForwardX11 no
</code>

replace USER_NAME_AT_CERN by your actual user name at CERN).



If you are not at CERN, see configuration advice for Windows and Linux/Unix, or just log on LXPLUS at CERN:

<code>$ ssh <your_username>@lxplus.cern.ch
</code>

In order to access a project using https authorization, just execute this:
<code>$ svn co https://svn.cern.ch/reps/<your_project>
</code>
