TeamForge-Git integration: Enable history protection

You can turn on history protection for the entire integration server or for an individual Git repository.

To turn on history protection server-wide (for all the repositories hosted on the Git integration server), do the following:
1. Set GERRIT_FORCE_HISTORY_PROTECTION=true in /opt/collabnet/teamforge/runtime/conf/runtime-options.conf.
2. Restart the gerrit service.
  - /etc/init.d/collabnet restart gerrit
Note: If you enable history protection server–wide, it cannot be overridden (turned off) for an individual Git repository. It will remain in effect for all Git repositories on the integration server.
To turn on history protection for an individual Git repository in a TeamForge project, select the Protect History option while creating the repository. For an existing repository, do the following:
1. On the Source Code page, select the Git repository and click Edit
2. Select the Protect History check box.
3. Click Save.

You can turn history protection on or off any time. However, your change will not be reflected in Gerrit immediately. It will be effective after the time that you defined as the regular refresh interval while installing the Git integration.

If you want your change to take effect immediately, do this right after you select or clear the Protect History check box: as a user with Source Code Admin permission, temporarily remove any user having a project role with any SCM permission, and then add that user back. This will trigger an immediate sync which will enable history protection. After that, the Gerrit Administrator will be able to see History Protection enabled in the Gerrit web interface (by logging in as a Gerrit Administrator and clicking the General link for the project with the name of the Git repository).
