Commands and help

Version of SVN

Check version with svn --version (should be 1.4). If not: Install proper version from RPMcompatSLC4

Install SVN

yum install subversion

svn help

svn help <command> e.g. svn help resolved

svn and password

If svn requires a password, try ssh svn.cern.ch and accept the update of the hostnames. See also .ssh/config.
Check if you have a valid kereberos ticket (update it by kinit if in doubt) and add the following to ~/.ssh/config:

    Host svn.cern.ch svn
    GSSAPIAuthentication yes
    GSSAPIDelegateCredentials yes
    Protocol 2
    ForwardX11 no

svn Atlas directories on web

Example: https://svn.cern.ch/reps/atlasoff/AtlasEvent, requires afs password.

   svn co https://svn.cern.ch/reps/atlasoff/AtlasEvent

Scan directories from trac
https://svnweb.cern.ch/trac/atlasoff/browser,   https://svnweb.cern.ch/trac/atlasgrp/browser,   https://svnweb.cern.ch/trac/atlasusr/browser,

Special Atlas setup at ccali

For releases >=15.3.0 python/svn is included in the distribution. At ccali for releases before 15.3.0 have to do once

   cp -a  /afs/cern.ch/atlas/software/dist/AtlasSettings/AtlasSettings-03-02-18/share  $HOME/mycmthome

and then each time after the usual source $HOME/cmthome/setup.sh

   export CMTHOME=$HOME/mycmthome

At ccali machines python with its module svn (here pysvn) are not installed at the place, where CMT expects them, namely /usr/local/python

 > source /usr/local/bin/python25_env.sh
 > python
>>> import pysvn;        # import svn does not work

Recursive checkout

The simple cmt -R command no longer works. Use instead the commands below. Example for checking out the full AtlasSimulation

   cmt co -R -r AtlasSimulation-15-02-00 -vd 15.2.0 AtlasSimulation

replace with

cat /afs/cern.ch/atlas/software/builds/AtlasSimulation/15.2.0/AtlasSimulationRelease/cmt/requirements | awk '{print $3}' > tags
pkgco -f tags

or

   cat /afs/cern.ch/atlas/software/builds/AtlasSimulation/15.2.0/AtlasSimulationRelease/cmt/requirements | awk '{print "cmt co -r " $3 " " $4 "/" $2}' > tags
   source tags

cmthome/requirements recommendations

cmthome/requirements

Use

   macro ATLAS_TEST_AREA "$PWD" 

and then

   cd <my work area>
   source ~/cmthome/setup.sh -tag=...
