Microsoft Windows Vista Error 0x80070091 and Cygwin

In Windows Vista I installed JBoss.  When I then logged in as another user for some reason all the JBoss directories had no permissions, i.e. their permissions were 000.  I ignored this and went ahead and copied one of the server directories.  Then I tried to go into the copied server directory and could not.

Thinking something was funky I tried to delete the whole JBoss directory but got this maddening and uninformative window.

Microsoft Windows Vista Error 0x80070091

I googled for a long time but could not find a satisfying solution.  I gave myself full control permissions for all files and folders but that did not help.  Then I noticed that if I clicked on one of the directories that Windows Vista was not letting me delete I would be prompted for permission to enter this directory.  Then I would repeat this process for all directories within.  After doing this I could delete that directory.

I then looked in Cygwin and found out what Vista had done, it had simply given the directory read and write permission.

Therefore the simple solution was to do the following:

chmod -R 500 .

After doing that simple change I could remove everything.

Subversion on Dreamhost

This post is a log of how I personally got Subversion running on Dreamhost using this post.

  1. Obtained the Subversion source from, compiled it, and put the binaries in my ~/bin directory.
  2. Added the Subversion binaries to my path by adding these lines to my ~/.bash_profile file.
    # Set PATH so it includes user's private bin if it exists
    if [ -d ~/bin ] ; then

    For this change to take effect you either have to relogin or:

    $ . ~/.bash_profile

  3. Initialized new subversion repositories. For example:
    $ svnadmin create ~/svn/mk 
    $ svn mkdir \
        file:///home/fkim/svn/mk/trunk \ 
        file:///home/fkim/svn/mk/branches \

    I am following the suggested way of organizing a Subversion repository.

  4. Imported the files into the subversion repository. For example:
    svn import ~/ file:///home/fkim/svn/mk/trunk/
    svn import ~/ svn+ssh://

    Note: I was having a strange problem when I tried to do an import and kept getting an already exists error.  It turned out the problem was because what I was trying to import was a link instead of the actual directory.  This might only be an issue on Cygwin.

  5. Checked the files out. To do this locally:
    svn co file:///home/fkim/svn/mk/trunk

    To do this remotely:

    svn co svn+ssh:// mkrb
