• Recursively fetching properties from a repository (low-level API)

SVNRepository.getStatus() vs. SVNRepository.getDir()

Here we will show how you can fetch properties from the repository recursively in a single request using SVNRepository. Many newbie users who come across the SVNRepository interface for the first time, decide to implement the task of recursive retrieving properties from a repository tree with the help of SVNRepository's getDir() method. To get properties recursively you'll have to call getDir() in recursion. It's not a wrong way, but consider the repository tree with multiple leaves (with hundreds or maybe thousands of them). For each directory leave getDir() sends a new request what leads to extremely slow performance.

Basically, what you do with getDir() is the following:

   1     public void fetchPropsFromRepository(SVNRepository repos, String path, long revision, Map pathsToProps, ) throws SVNException {
   2         SVNProperties props = new SVNProperties();
   3         Collection children = repos.getDir(path, revision, props, SVNDirEntry.DIRENT_ALL, null);
   4         pathsToProps.put(path, props);
   5         for (Iterator childrenIter = children.iterator(); childrenIter.hasNext();) {
   6             
   7     }
