| | | * Sample Gitblit Pre-Receive Hook: protect-refs |
| | | * |
| | | * This script provides basic authorization for receive command types for a list |
| | | * of known ref patterns. Command types and unmatched ref patterns will be |
| | | * ignored, meaning this script has an "allow by default" policy. |
| | | * |
| | | * This script works best when a repository requires authentication on push, but |
| | | * can be used to enforce fast-forward commits or prohibit ref deletion by |
| | | * setting the authorizedTeams variable to an empty list. |
| | | * |
| | | * The Pre-Receive hook is executed after an incoming push has been parsed, |
| | | * validated, and objects have been written but BEFORE the refs are updated. |
| | | * This is the appropriate point to block a push for some reason. |
| | | * |
| | | * This script is only executed when pushing to *Gitblit*, not to other Git |
| | | * tooling you may be using. |
| | | * |
| | | * If this script is specified in *groovy.preReceiveScripts* of gitblit.properties |
| | | * or web.xml then it will be executed by any repository when it receives a |
| | | * push. If you choose to share your script then you may have to consider |
| | | * tailoring control-flow based on repository access restrictions. |
| | | * |
| | | * Scripts may also be specified per-repository in the repository settings page. |
| | | * Shared scripts will be excluded from this list of available scripts. |
| | | * |
| | | * This script is dynamically reloaded and it is executed within it's own |
| | | * exception handler so it will not crash another script nor crash Gitblit. |
| | | * |
| | | * If you want this hook script to fail and abort all subsequent scripts in the |
| | | * chain, "return false" at the appropriate failure points. |
