Many questions arise when it comes to the topic what are shelves, how to use them and why could it be useful to do so at all. To lit some light on the question at first it’s needed to explain a bit the difference between branches in Git and branches in SVN. In SVN branch is represented by a directory and files inside that directory are commits. In Git there is no direct association between a commit and a branch. Commits in Git contain various information e.g. unique SHA1, author, time and date of creation, SHA1 of the parent commit, but do not contain the name of the branch in which they have been created. Therefore to translate commits from Git to SVN and to assign all commits to their branches SubGit uses a special algorithm that logically analyses all given data and makes usually a very wise conclusion about to where each commit belongs. But sometimes it is not quite obvious a decision as in some particular cases it’s not possible to determine one commit’s branch. And at that exact moment shelves come into the scene.

Some of you may know that we are already working on the next version of our tool, SubGit 2.0. This new version enables bi-directional synchronization of Git and SVN repositories located on different hosts.
Usually we talk about creating a Git mirror of existing Subversion repository. However, SubGit makes no difference between two and it is equally easy to create Subversion mirror of a Git repository (or merely translate Git repository to Subversion). Here is how:
Recently we were given a task to create a readonly Git mirror of a Subversion repository. We’ve used SubGit and svnsync to accomplish this task, all went pretty smooth and I’ve decided to publish a small HOWTO on that topic.
We use our SubGit product for self-hosting for more than a year already, but until now we didn’t have Git side of repository open for the public. Today I’ve found some time to make necessary changes to the Apache configuration and, voilà, our dear users may now use Git to get SVNKit or SqlJet source code. Just run:
Finally, we’ve released SubGit 1.0!
Today I’d like to describe how to migrate from Svn to Git, minding existing infrastructure. One of the most common Subversion servers configurations is Linux server with Apache and mod_dav_svn module serving one or more Subversion repositories. Each Subversion repository may contain one or more projects. Of course, I will use SubGit to make migration smooth, i.e. without a need to force users to make a switch from Subversion to Git overnight.
I’d like to start this blog with a few real-world examples on how to set up SubGit assuming infrastructure that is already in place. This post will take place in a strange world of Windows.
