  • How to Getting A Repository History With SVNKIt

    In this example we'll demonstarte how you may get the history of changes made to a repository (i.e perform a log operation) starting with the very first revision and up to the very last one.

    public class History {
    
        public static void main( String[] args ) {
            DAVRepositoryFactory.setup( );
    
            String url = "http://svn.svnkit.com/repos/svnkit/trunk/doc";
            String name = "anonymous";
            String password = "anonymous";
            long startRevision = 0;
            long endRevision = -1; //HEAD (the latest) revision
    
            SVNRepository repository = null;
            try {
                repository = SVNRepositoryFactory.create( SVNURL.parseURIEncoded( url ) );
                ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager( name, password );
                repository.setAuthenticationManager( authManager );
    
                ...
                Collection logEntries = null;
                
                logEntries = repository.log( new String[] { "" } , null , startRevision , endRevision , true , true );
                ...

    We don't use paths to get only those revisions where paths were changed, so we pass an empty array new String[] { "" } to the log(...) method of the repository access driver.

    The second parameter is a Collection to receive history objects. Information about each revision is represented by a single SVNLogEntry object. We pass null since we don't need to fill an existing collection with history objects.

    Then we pass a range of revisions for which the history of changes to be fetched out.

    The fifth parameter controls whether information of all changed paths per revision should be included into histroy objects. Such information is represented by an SVNLogEntryPath object for each revision. We are going to print out all changed paths, so setting it to true.

    And the last parameter stricts node's history only to the node itself, what means that history of the node's ancestor (if the node has been copied) won't be included.

    Now let's print the collected information:

    for ( Iterator entries = logEntries.iterator( ); entries.hasNext( ); ) {
                SVNLogEntry logEntry = ( SVNLogEntry ) entries.next( );
                System.out.println( "---------------------------------------------" );
                System.out.println ("revision: " + logEntry.getRevision( ) );
                System.out.println( "author: " + logEntry.getAuthor( ) );
                System.out.println( "date: " + logEntry.getDate( ) );
                System.out.println( "log message: " + logEntry.getMessage( ) );
    
                if ( logEntry.getChangedPaths( ).size( ) > 0 ) {
                    System.out.println( );
                    System.out.println( "changed paths:" );
                    Set changedPathsSet = logEntry.getChangedPaths( ).keySet( );
    
                    for ( Iterator changedPaths = changedPathsSet.iterator( ); changedPaths.hasNext( ); ) {
                        SVNLogEntryPath entryPath = ( SVNLogEntryPath ) logEntry.getChangedPaths( ).get( changedPaths.next( ) );
                        System.out.println( " "
                                + entryPath.getType( )
                                + " "
                                + entryPath.getPath( )
                                + ( ( entryPath.getCopyPath( ) != null ) ? " (from "
                                        + entryPath.getCopyPath( ) + " revision "
                                        + entryPath.getCopyRevision( ) + ")" : "" ) );
                    }
                }
            }

    And finally we run the program and have the following output in our console:
