| | | * Sample Gitblit Pre-Receive Hook: protect-refs |
| | | * |
| | | * This script provides basic authorization for receive command types for a list |
| | | * This script provides basic authorization of 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. |
| | | * setting the *authorizedTeams* variable to an empty list and adding a ".+"
|
| | | * entry to the *protectedRefs* 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 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. |
| | | * This script may reject one or more commands, but will never return false.
|
| | | * Subsequent scripts, if any, will always be invoked.
