CVS on PDB Backup

• Physics Databases have a db4lcg CVS repository created on CERN Central CVS Service
• There is a passwordless access to the CVS already configured on pdb-backup machines
• There are already several projects imported into CVS:
  • 3dmon - 3D monitoring php pages (Streams monitoring, interventions, etc.)
  • backup5 - currently including all backup scripts used by Physics Databases
  • inventory - new Java based hardware inventory
  • production - all production scripts used by the service
  • rac_mon - RACMon python scripts and configs
  • racsec - RAC security project
  • streams - all streams related scripts
  • strmmon - Streams monitoring daemon

Tutorial

• to update a project from CVS (synchronize CVS changes to disk) use the update command:
  • goto any CVS directory on disk and run cvs update:

    cd ~/strmmon
    cvs update

  • this will update strmmon directory (and subdirectories) by fetching all the changes from CVS

• to add new directories or files into a project use the add command:
  • goto any CVS directory on disk and run cvs add ...:

    cd ~/strmmon
    cvs add new_dir
    cvs add new_dir/new_file1 new_dir/new_file2
    

  • IMPORTANT - this will just schedule addition of new_file1 and new_file2 and new_dir, please use cvs commit to finalize it (see below)

• to commit a modified project into CVS (synchronize disk changes to CVS) use the commit command:
  • goto any CVS directory on disk and run cvs commit:

    cd ~/streams/ATLAS
    cvs commit

  • this will commit any changes done in ATLAS directory of streams project into CVS

• to get a project from CVS into a new directory (or machine) use the checkout (co) command:
  • goto the base directory, where you want to checkout the project and run cvs checkout:

    cd ~/my_directory
    cvs co production

  • this will create production directory and will checkout production project (including subdirectories) from CVS

• to import a new project into CVS use the import command (this has already been done for most of our projects):
  • goto the directory to be imported and run cvs import:

    cd /backup5
    cvs import -m "Initial import" -I ! -I "*.log*" -I "*.dmp*" backup5 PhyDB start

  • backup5 will be the new project name
  • use several -I options to exclude specific files from the import
