Is it possible to do an svnsync between a folder inside a repository and a repository?

Question

I have two repositories but I want to sync only a folder inside repository 1 with repository 2. Is that possible? For example...

• repo 1: clientA/appA
• repo 2: appA

The problem is I don't have rights to modify the two SVN repositories. My task is just to sync them both via Jenkins.

To give you more background, below are the designs of the 2 SVN repositories.

1. svn 1

   • clientA
     • appA
     • appB
   • clientB
     • appC
     • appD

2. svn 2

   • appA
   • appB
   • appC
   • appD

Thanks in advance.

Answer 1

Yes, this is possible. Configure access permissions on the source repository to restrict svnsync user account to access all repository paths except the one you want to sync to target repository. The case is briefly described in Apache Subversion FAQ:

An alternative approach is to replicate the repository with svnsync after configuring path-based authorization rules that deny read access to any paths that need to be filtered from history. Unlike svndumpfilter, svnsync will automatically translate copy operations with an unreadable source path into normal additions, which is useful if history involving copy operations needs to be filtered.
