Deliverables of this phase:

• Subversion 1.4.x
• Duplicate user management infrastructure of existing svn.mit.edu service
• Cement details of rollout process
• Existing svn.mit.edu repositories are migrated over
• svn.mit.edu becomes separate from cvs.mit.edu

Setup notes for map-dev-svn1.mit.edu prototype server:

• The server is an ops VM image running RHEL 5 with AFS and update_server installed.  The standard IPS user accounts are also installed.
• Subversion setup:
  • Created user "svn" alongside the IPS accounts.
  • Grab Subversion 1.4.6 from subversion.tigris.org, put in /home/svn/src
  • No need to grab the deps tarball; RHEL 5 has adequate versions of those
  • Need to install some development packages: yum install apr-devel apr-util-devel neon-devel zlib-devel
  • Untar into /home/svn/src/subversion-1.4.6
  • Run ./autogen.sh to work around some libtool issue with 64-bit libraries
  • Do build with: ./configure --without-berkeley-db --prefix=/home/svn && make && make install

Next steps:

• Get DCM set up from moira (by ops) and received on map-dev-svn1.  Mark Manley is working on the update_server port for receiving the DCM.
• Get a repository created on svn.mit.edu for supporting materials
• Identify supporting materials (exec-svnserve, DCM scripts, cron jobs, etc.) and put into repository with documentation

Pieces of the user management system on the existing svn.mit.edu:

• A DCM manages /etc/group.local to contain all of the groups in the moira list cvs-groups.
• A DCM manages /etc/passwd.moira to contain all of the users in the moira list cvs-users.
• /etc/athena/postacldcm combines /etc/passwd.local.head and /etc/passwd.moira with some modifications into /etc/passwd.local which is then copied into /etc/passwd.
• /etc/athena/postacldcm modifies /etc/group.local in place and then copies it into /etc/group.
• Some snap accounts have entries in /etc/passwd.local.head and do not exist in Moira.  Those accounts are added to specific groups in /etc/group.local by postacldcm before updating /etc/group.
• Other snap accounts exist in Moira.  Those accounts do not need to be added to group.local by postacldcm, but do need their passwd entries modified by postacldcm.
• Since the existing server is an Athena machine, SSH access is managed by /etc/athena/access, which contains "*inpasswd rl" to allow all users in the passwd file to log in via SSH.
