Applying a local change to a ruleset

This page describes a method for making a temporary local change (hotfix) to a ruleset. Such a hotfix can be used temporarily for testing. If the change is to be kept permanently, it is advisable to deploy the change using Ansible.

The commands below can be executed using the iRODS service account.

1. First clone another copy of the ruleset:

   cd /etc/irods
   git clone https://github.com/UtrechtUniversity/yoda-ruleset.git hotfix
   

2. Make changes to the ruleset (for example, meta.py) and compile the ruleset:

   cd hotfix
   vim meta.py
   make install
   

3. Change the symlink to the fixed ruleset:

   cd /etc/irods
   ln -sfn hotfix rules_uu
   

If the change does not have the desired result, revert to the old ruleset by changing the symlink back and compiling the ruleset:

cd /etc/irods
ln -sfn yoda-ruleset rules_uu
cd yoda-ruleset
make install
