Mirror SVN Repository [Write-through proxying]

问题:

I have a codebase located in Europe and access this codebase from Asia. Codebase is substantially huge, downloading the whole codebase (which is required sometimes) becomes a pain.

I wanted to know whether anything like this.

I want a solution that "I will have a svn server locally which will sync with the main svn and serve my team as the svn is locally hosted."

Thanks in advance

Try Multisite Repository Replication with VisualSVN Server. That's exactly what you were looking for then.

Multisite Repository Replication enables classic master/slave replication architecture which allows you to setup a master repository at your main codebase location in Europe with multiple slaves at other locations.

In contrast to standard write-through proxy solution, in Multisite Repository Replication feature

• master and slave repository looks and acts just like a regular writeable Subversion repository,

• the replication between master ans slaves is performed automatically and transparently,

• supports advanced authentication mechanisms,

• It's easy to setup, works out-of-the-box with minimal configuration via VisualSVN Server Manager MMC console.

You can also try a write-through-proxy which is supported since SVN 1.5 and works fine.

With this setup you have a master and a slave repository.

The slave repo acts as a local read cache while commits will be proxied to your master server and synced back.

This solution comes with subversion / apache.

See this svndevelopers blog for more details. Or the superb SVN book, or last but not least the subtrain admin training presentations

Here is a pretty good article on how to set this up:

http://wordaligned.org/articles/how-to-mirror-a-subversion-repository

The general idea is to use svnadmin hotcopy to do the copy without down time, perhaps triggered by a post-commit hook, or on a timer.

Another option, discussed here:

http://blogs.collab.net/subversion/2007/08/mirroring-repos/

Is to use SVN sync to do a sync, rather than a copy, using the svnsync synchronize command.

Besides the svnsync, you can try the commercial solution from Wandisco.
