Class SafeArchiveServingAction

java.lang.Object

net.masterthought.jenkins.SafeArchiveServingAction

All Implemented Interfaces:

hudson.model.Action, hudson.model.ModelObject

Direct Known Subclasses:

SafeArchiveServingRunAction

public class SafeArchiveServingAction
extends Object
implements hudson.model.Action

This class implements a solution to serving various reports using JavaScript, Flash, etc. from Jenkins. By default, Jenkins serves static files using a restrictive Content-Security-Policy header to prevent malicious users from attacking other users of Jenkins by having Jenkins serve them maliciously manipulated files. This presents an obstacle to plugins that wish to archive known safe reports in HTML format and have Jenkins serve them. Examples include the Maven Site functionality in Maven Plugin, or the Javadoc Plugin. This class implements a safe alternative to serving files from DirectoryBrowserSupport: This action, when first attached, scans the specified directory and records all files' checksums. When later asked to serve files, it compares the actual and expected checksums, and only serves matching files.

Constructor Detail

SafeArchiveServingAction

public SafeArchiveServingAction(File rootDir,
                        String urlName,
                        String indexFile,
                        String iconName,
                        String title,
                        String... safeExtensions)

Create a safe archive serving action.

Parameters:

rootDir - The root directory to be served by this action

urlName - The URL name used for this action

indexFile - The file name of the index file to be served when accessing the urlName URL

iconName - The icon used for the action in the side panel

title - The title of this action in the side panel

safeExtensions - The file extensions to be skipped from checksum recording and verification. These are file types whose unauthorized modification does not constitute a risk to users when viewed in a web browser. This should be resource file extensions like "gif" or "png" or file extensions of files not viewed in a browser like "zip" or "gz". Never specify file types possibly containing scripts or other possibly malicious data that can exploit users' browsers (html, js, swf, css, …).
