Re: [PATCH][merge-tracking]code cleanup of append_component_to_paths

hi jaya, i have written my won class to commit url and file is hard coded. the following is the code. i am running in the eclipse. import java.io.ByteArrayInputStream; import org.tmatesoft.svn.core.SVNCommitInfo; import org.tmatesoft.svn.core.SVNErrorCode; import org.tmatesoft.svn.core.SVNErrorMessage; import org.tmatesoft.svn.core.SVNException; import org.tmatesoft.svn.core.SVNNodeKind; import org.tmatesoft.svn.core.SVNURL; import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager; import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory; import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl; import org.tmatesoft.svn.core.io.ISVNEditor; import org.tmatesoft.svn.core.io.SVNRepository; import org.tmatesoft.svn.core.io.SVNRepositoryFactory; import org.tmatesoft.svn.core.io.diff.SVNDeltaGenerator; import org.tmatesoft.svn.core.wc.SVNWCUtil; /* * This is an example of how to commit several types of changes to a repository: * a new directory with a file, modification to a file, copying a directory into * a branch, deletion of the directory and its entries. * * Main aspects of performing a commit with the help of ISVNEditor: * 0)initialize the library (this is done in setupLibrary() method); * * 1)create an SVNRepository driver for a particular repository location, that * will be the root directory for committing - that is all paths that are being * committed will be below that root; * * 2)provide user's authentication information - name/password, since committing * generally requires authentication); * * 3)"ask" your SVNRepository for a commit editor: * * SVNRepository.getCommitEditor(); * * 4)perform a sequence of descriptions of changes to the repository server (for * example, here you "say" to the server that you have added such-and-such a new * directory at such-and-such a path as well as a new file). These descriptions * are calls to ISVNEditor's methods. First of all, ISVNEditor.openRoot() is * called to 'open' the root directory; * * 5)at last you close the editor with the ISVNEditor.closeEdit() method that * fixes your modificaions in the repository finalizing the commit. * * For each commit a new ISVNEditor is required - that is after having been * closed the editor can no longer be used! * * This example can be run for a locally installed Subversion repository via the * svn:// protocol. This is how you can do it: * * 1)after you install the Subversion pack (available for download at * http://subversion.tigris.org/) you should create a new repository in a * directory, like this (in a command line under a Windows OS): * * >svnadmin create X:\path\to\rep * * 2)after the repository is created you can add a new account: navigate to your * repository root (X:\path\to\rep\), then move to \conf and open the file * 'passwd'. In the file you'll see the section [users]. Uncomment it and add a * new account below the section name, like: * * [users] * userName = userPassword. * * In the program you may further use this account as user's credentials. * * 3)the next step is to launch the custom Subversion server (svnserve) in a * background mode for the just created repository: * * >svnserve -d -r X:\path\to * * That's all. The repository is now available via svn://localhost/rep. * */ public class CommitHandler{ public static void main(String[] args) { /* * Initialize the library.
