Dirac in a box (Basic Setup)

• Setup yourself up with a hostcert and a EMI UI, eg by following these instructions.
• Open the relevant ports (add these lines to the /etc/sysconfig/iptables before the REJECT all else) :

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 9130:9200 -j ACCEPT

now run: service iptables restart

• Install git (and emacs ;-).
• Make a dirac user, and copy the hostcert/key into .globus
• su - dirac
• Set git up correctly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

• You also need the ssh key you use on github
• To save you from typos (the script does not deal well with that :-D ) use

   eval "$(ssh-agent)"  followed by ssh-add -t 1h

•  git clone git@github.com:ic-hep/DIRAC-tools.git 

•  DIRAC-tools/dirac_in_a_box.py /opt/dirac/ git@github.com:ic-hep 

• Ignore "Exception _mysql_exceptions.ProgrammingError" errors
• Test your server.

Fixing a bug/adding a feature :-)

• take ownership of the bug/feature you want to fix
• make a branch: Example: The branch is bug1 and the modified file is ConfigurationSystem/Client/CSCLI.py:

 cd /opt/dirac/DIRAC
 git status (should say "# On branch rel-v6r12")
 git pull
 git branch bug1
 git checkout bug1 
 git status (should say "# On branch bug1")

• now add your code/restart the relevant components and test your code :-)

 git add ConfigurationSystem/Client/CSCLI.py
 git commit -m "CLI to accept ctrl-D"
 git status
 

• and push it back to github

 git push -u origin bug1
 

• Now go to the git repo webpage and issue a pull request (ensuring to send the request to our (ic-hep) repo, not the main DIRAC repo - check the defaults using the Edit button in the top right corner !!)
• Finally: Switch back to main branch

 git checkout rel-v6r12
 

and delete the local copy of the bug1

 git branch -d bug1
