I’m trying to setup Xcode SCM using Subversion (SVN) on a network disk (mounted).

I’m trying to setup Xcode SCM using Subversion (SVN) on a network disk (mounted). I was able to setup SVN repository on my machine locally, and everything worked smoothly without any hassle. Reference Article: Version Control is Your Friend by Jeff LaMarche

My problem is that I’m unable to set-up SVN on a network drive (mounted).

cd [mounted_drive]/Users/Shared 
mkdir subversion 
cd subversion 
mkdir HelloWorld 
svnadmin create HelloWorld
chmod -R 777 HelloWorld

The above commands work fine and main subversion repository is successfully created. The problem is that it doesn’t allow me to create sub-folders (trunk, branch, and tag) in the main SVN repository. 

svn mkdir
file:///[mounted_drive]/Users/Shared/Subversion/HelloWorld/trunk
file:///[mounted_drive]/Users/Shared/Subversion/HelloWorld/branch
file:///[mounted_drive]/Users/Shared/Subversion/HelloWorld/tag

When i try to run the svn mkdir command above, I get the following svn error:

“svn: Can’t get exclusive lock on file
‘[mounted_drive]/[subversion_repository_directory]/db/write-lock’: Operation not supported”

If i control the remote machine, and run the above command natively, it works and trunk, branch and tag directories are created.

After setting the Xcode’s SCM to the remote repository, if i try to “Import” code into this repository (remotely), Xcode returns the following error:

“svn: Can’t get exclusive lock on file
‘[mounted_drive]/[subversion_repository_directory]/db/transactions/3-1.txvn/rev-lock’: Operation not supported”

Crux of this whole story: I’m facing a lot of issues while setting-up SVN on a network drive. Any help will be greatly appreciated.

    Go read the book. I’ll wait. Seriously.

    Do not set up a shared repository by tossing it on a network drive and then talking to it via file:///. file:/// access to repositories is only meant for local disk because of (among other things) the locking semantics of network file systems.

    Instead, choose a computer on which you’ll keep your repositories. Let’s call it Hezikiah Run svnserve on that system to make the repositories available on the network. Access your repository as svn://hezikia/REPO_NAME.

    The book is a great help there.
