Rudder

When we edit a rule category with the little pen that appears on mouse over the category name, then the category XML file on /var/rudder/configuration-repository/ruleCategories is removed.

The corresponding commit message is:

  Move archive of node group category with ID 'aaab98ef-8d7d-4948-9213-13ed93df8ebf'

Of course, it's the first silent move that leads to Ragnärok and a chess mate in one move: from that point, if the user use the archive -> restore [rules] -> from last commit; then the category disapear, and any rule that uses it will have a wonderfull "ERROR" as a category name.

This is bad, developpers !

It was reproduce in 2.10 and 3.0.

Procedure to restaure rule categories deleted during a restore:

$ cd /var/rudder/configuration-repository
# find candidate rule categories (deleted with a "move" message)
$ git log --diff-filter='D*' --grep="Move archive" --format=format:%H ruleCategories > /tmp/possible_categories.txt
# find rule really moved and not deleted due to the bug
$ git log --diff-filter='A' --grep="Move archive" --format=format:%H ruleCategories > /tmp/real_move.txt
# restore rule categories on the fs
$ for i in $(grep -v -f /tmp/real_move.txt /tmp/possible_categories.txt); do git show --no-color $i | patch -p1 -R; done
# add them back in git
$ git add ruleCategories/
$ git commit -m "restore categories from bug" 

And then, go to utilities -> archive, and "restore rules" from "latest git commit" in the dropdown list.
