Offer Git operations for a number of parallel accounts

Current Situation

• JOC Cockpit offers Integration with Git repositories.
• A Git repository can be accessed from a single Git account only. If more than one JOC Cockpit account is used then they have to use the same Git account.

Desired Behavior

• Any number of JOC Cockpit accounts can be used and can be mapped to related Git accounts. Use of Git accounts works independently from the JOC Cockpit security level.
• Each JOC Cockpit user account's profile can hold an individual Git account.
• Git operations performed by JOC Cockpit on the command line using a Git Client
  • create an individual .gitconfig Git file in a temporary directory,
    • The .gitconfig Git file is created like this:

      mkdir /tmp/.gitconfig$$
      git config --file /tmp/.gitconfig$$/.gitconfig --add core.sshCommand "ssh -o StrictHostKeyChecking=no -i /var/sos-berlin.com/js7/joc/resources/joc/repositories/private/sos-community2_rsa"
      git config --file /tmp/.gitconfig$$/.gitconfig user.email monitor@sos-berlin.com
      git config --file /tmp/.gitconfig$$/.gitconfig user.name sos-community2
      git config --file /tmp/.gitconfig$$/.gitconfig --add safe.directory /var/sos-berlin.com/js7/joc/resources/joc/repositories/rollout/sp-js7-demo-rollout-test
      

• • • The temporary directory and Git file are created per API request related to Git operations and to operations reading and writing files from/to the local repository.
  • copy the individual Git .gitconfig file to the global $HOME/.gitconfig file. This operation is performed before each execution of the Git Client.
• Git operations are performed in transactions per Git repository:
  • Any number of parallel Git operations can be performed as long as the same Git repository is not used in parallel.
  • Access to the same Git repository is serialized in a way that makes Git operations wait for completion of a parallel operation. A timeout of 60s is applied to wait for a parallel transaction to complete. If the timeout is exceeded then the user receives an error message and can restart the Git operation.
