Interface ISVNAuthenticationManager

  • All Known Subinterfaces:

    All Known Implementing Classes:
    BasicAuthenticationManager

    public interface ISVNAuthenticationManager
    The ISVNAuthenticationManager is implemented by manager classes used by SVNRepository drivers for user authentication purposes.

    When an SVNRepository driver is created, you should provide an authentication manager via a call to:

     import org.tmatesoft.svn.core.io.SVNRepository;
     import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager;
     ...
         SVNRepository repository;
         ISVNAuthenticationManager authManger;
         ...
         
         repository.setAuthenticationManager(authManager);
         ...

    SVNKit provides a default authentication manager implementation - org.tmatesoft.svn.core.internal.wc.DefaultSVNAuthenticationManager. This manager has got the following features:

    • uses the auth storage from the default Subversion runtime configuration area;
    • may use the auth storage in the directory you specify;
    • uses the ssh, ssl & proxy options from the standard config and servers files;
    • stores credentials in the in-memory cache during runtime;
    You may also specify your own auth provider (ISVNAuthenticationProvider) to this default manager, it will be used along with those default ones, that implement the features listed above.

    If using the https:// protocol and if no user's authentication provider implementation is set to the default manager, server certificates are accepted temporarily and therefore are not cached on the disk. To enable server CAs caching, a user should set an authentication provider implementation which acceptServerAuthentication() method must return ISVNAuthenticationProvider.ACCEPTED. That will switch on certificate on-the-disk caching.

    How to get a default auth manager instance see SVNWCUtil.

    • Method Detail

      • setAuthenticationProvider

        void setAuthenticationProvider​(ISVNAuthenticationProvider provider)
        Sets a custom authentication provider that will provide user credentials for authentication.
        Parameters:
        provider - an authentication provider
      • getProxyManager

        ISVNProxyManager getProxyManager​(SVNURL url)
                                  throws SVNException
        Returns a proxy manager that keeps settings for that proxy server over which HTTP requests are send to a repository server.

        A default auth manager uses proxy settings from the standard servers file.

        Parameters:
        url - a repository location that will be accessed over the proxy server for which a manager is needed
        Returns:
        a proxy manager
        Throws:
        SVNException
      • getTrustManager

        javax.net.ssl.TrustManager getTrustManager​(SVNURL url)
                                            throws SVNException
        Returns a manager which handles trust data for the specified url.

        Note: in pre-1.2.0 versions ISVNAuthenticationManager used to provide ISVNSSLManager via a method getSSLManager() which is now replaced by this one. ISVNSSLManager is no longer used (replaced by TrustManager).

        Parameters:
        url - repository url
        Returns:
        trust manager
        Throws:
        SVNException

      • getFirstAuthentication

        SVNAuthentication getFirstAuthentication​(java.lang.String kind,
                                                 java.lang.String realm,
                                                 SVNURL url)
                                          throws SVNException
        Retrieves the first user credential. The scheme of retrieving credentials:
        • For the first try to authenticate a user to a repository (using the specifed realm) an SVNRepository driver calls getFirstAuthentication() and sends the retrieved credential.
        • If the credential is accepted, it may be stored. If not, the driver calls getNextAuthentication() and sends the next credential.
        • If the last credential was not accepted, the driver still tries to get the next credential for the same realm.

        For each credential kind an implementor should return a kind-specific credential. The following table matches kinds to proper credential classes:

        Credential Kind Credential Class
        PASSWORDSVNPasswordAuthentication
        SSHSVNSSHAuthentication
        SSLSVNSSLAuthentication
        USERNAMESVNUserNameAuthentication
        Parameters:
        kind - a credential kind
        realm - a repository authentication realm
        url - a repository location that is to be accessed
        Returns:
        the first try user credential
        Throws:
        SVNException
      • getNextAuthentication

        SVNAuthentication getNextAuthentication​(java.lang.String kind,
                                                java.lang.String realm,
                                                SVNURL url)
                                         throws SVNException
        Retrieves the next user credential if the first try failed. The scheme of retrieving credentials:
        • For the first try to authenticate a user to a repository (using the specifed realm) an SVNRepository driver calls getFirstAuthentication() and sends the retrieved credential.
        • If the credential is accepted, it may be stored. If not, the driver calls getNextAuthentication() and sends the next credential.
        • If the last credential was not accepted, the driver still tries to get the next credential for the same realm.

        For each credential kind an implementor should return a kind-specific credential. The following table matches kinds to proper credential classes:

        Credential Kind Credential Class
        PASSWORDSVNPasswordAuthentication
        SSHSVNSSHAuthentication
        SSLSVNSSLAuthentication
        USERNAMESVNUserNameAuthentication
        Parameters:
        kind - a credential kind
        realm - a repository authentication realm
        url - a repository location that is to be accessed
        Returns:
        the next try user credential
        Throws:
        SVNException
      • acknowledgeAuthentication

        void acknowledgeAuthentication​(boolean accepted,
                                       java.lang.String kind,
                                       java.lang.String realm,
                                       SVNErrorMessage errorMessage,
                                       SVNAuthentication authentication)
                                throws SVNException
        Accepts the given authentication if it was successfully accepted by a repository server, or not if authentication failed. As a result the provided credential may be cached (authentication succeeded) or deleted from the cache (authentication failed).
        Parameters:
        accepted - true if the credential was accepted by the server, otherwise false
        kind - a credential kind (PASSWORD or SSH or USERNAME)
        realm - a repository authentication realm
        errorMessage - the reason of the authentication failure
        authentication - a user credential to accept/drop
        Throws:
        SVNException
      • acknowledgeTrustManager

        void acknowledgeTrustManager​(javax.net.ssl.TrustManager manager)
        Acknowledges the specified trust manager. This method is called only when a secure connection is successfully established with the specified manager.
        Parameters:
        manager - trust manager to acknowledge (one returned by getTrustManager(SVNURL))
        Since:
        1.2.0
      • isAuthenticationForced

        boolean isAuthenticationForced()
        Checks whether client should send authentication credentials to a repository server not waiting for the server's challenge.

        In some cases it may be necessary to send credentials beforehand, not waiting until the server asks to do it itself. To achieve such behaviour an implementor should return true from this routine.

        Returns:
        true if authentication credentials are forced to be sent;false when credentials are to be sent only in response to a server challenge
      • getReadTimeout

        int getReadTimeout​(SVNRepository repository)
        Returns the read timeout value in milliseconds which repository should use in socket read operations. Socket read operations will block only for this amount of time.
        Parameters:
        repository - a repository access driver
        Returns:
        connection timeout value
        Since:

      • getConnectTimeout

        int getConnectTimeout​(SVNRepository repository)
        Returns the connection timeout value in milliseconds which repository should use in network connection operations.
        Parameters:
        repository - repository access object
        Returns:
        connection timeout value in milliseconds which will be set to a socket
