| | | /** |
| | | * Sample Gitblit Pre-Receive Hook: subgit |
| | | * http://subgit.com |
| | | * |
| | | * 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. |
| | | * |
| | | * This script may reject one or more commands, but will never return false. |
| | | * Subsequent scripts, if any, will always be invoked. |
| | | * |
| | | * Bound Variables: |
| | | * gitblit Gitblit Server com.gitblit.GitBlit |
| | | * repository Gitblit Repository com.gitblit.models.RepositoryModel |
| | | * receivePack JGit Receive Pack org.eclipse.jgit.transport.ReceivePack |
| | | * user Gitblit User com.gitblit.models.UserModel |
| | | * commands JGit commands Collection<org.eclipse.jgit.transport.ReceiveCommand> |
| | | * url Base url for Gitblit String |
| | | * logger Logs messages to Gitblit org.slf4j.Logger |
| | | * clientLogger Logs messages to Git client com.gitblit.utils.ClientLogger |
| | | * |
| | | * Accessing Gitblit Custom Fields: |
| | | * def myCustomField = repository.customFields.myCustomField |
| | | * |
| | | * |
| | | * Usage: |
| | | * |
| | | * 1. Create Git repository in GitBlit; |
| | | * 2. Register subgit pre-receive groovy hook in repository settings; |
| | | * 3. Install SubGit into created repository: |
| | | * subgit configure --svn-url <SVN_URL> <GITBLIT_HOME>/data/git/<GIT_REPO> |
| | | * subgit install <GITBLIT_HOME>/data/git/<GIT_REPO> |
| | | * |
| | | * You can enable SubGit pre-receive groovy hook for all repositories: this shouldn't |
| | | * cause any problems as the hook skips those repositories with no SubGit installed. |
