A problem

Submitted by Anonymous on Mon, 04/19/2010 - 12:46.

Hi, Thank you for this very good tutorial. I have setup svn with its help but I am getting error when I am starting httpd service. It is in "Apache subversion conf setup:" Unknown DAV provider: svn
Please let me know what I forget to install.

Thanks

dav svn module

Submitted by sandip on Mon, 04/19/2010 - 22:02.

Check that the dav svn module is loaded in apache conf via:

LoadModule dav_svn_module modules/mod_dav_svn.so

It should have it if you have installed "mod_dav_svn" as mentioned above.

fsfs repository type

Submitted by sandip on Tue, 09/16/2008 - 16:39.

In Subversion 1.1, a Berkeley DB repository is the default repository type, but an FSFS repository can be created using the --fs-type option:

$ svnadmin create /path/to/repos --fs-type fsfs

From the propaganda notes at: svn.collab.net, it seems that "fsfs" is a better option to BDB for the filesystem implementation to be used when creating new repositories.
