Subversion 1.7 support update

We’ve received a number of questions related to the support for Subversion 1.7 in IntelliJ IDEA 11 and related IDEs. With this post, we’d like to provide an update regarding the current status of the support and our future plans.

As you may know, IntelliJ IDEA relies on the SVNKit library for its Subversion support. Subversion 1.7 is a huge release in terms of the internal changes, and although the SVNKit team started work on it a long time ago, this work is unfortunately not yet finished.

We’ve been working closely with the SVNKit team and providing them feedback regarding the open issues that need to be resolved before we can fully rely on the new SVNKit in our integration. We’ve also included an experimental SVN 1.7 plugin in one of the beta releases of IntelliJ IDEA 11. However, due to major performance problems discovered during our testing, we’ve had to remove the plugin from the final release. Therefore, IntelliJ IDEA 11 and other IDEs based on the same version of the platform (PhpStorm/WebStorm 3.0, PyCharm 2.0) do not support Subversion 1.7.

However, we’re confident that the remaining open issues are going to be resolved in the coming months, and we plan to include full Subversion 1.7 support in the forthcoming IntelliJ IDEA 11.1 update, planned for release in late Q1/early Q2 2012. The Early Access Preview testing for IntelliJ IDEA 11.1 will begin early next year. Updates for PyCharm and PhpStorm/WebStorm will also be released around that time.

If you can’t wait for the IntelliJ IDEA 11.1 EAP to begin, you can build the plugin from source today. In our GitHub repo, the svn4idea plugin is the new plugin updated for SVN 1.7 compatibility and bundling the new SVNKit, and svn4ideaOld is the plugin currently shipped with IntelliJ IDEA 11.

Note that if your main reason for upgrading to SVN 1.7 is better update performance, you can achieve this with the exising IntelliJ IDEA integration and older SVN versions. In order to do that, please enable the “Update administrative information only in changed subtrees” option under Settings | Version Control | Subversion.

Also note that we do not currently plan to release SVN 1.7 compatible updates for IntelliJ IDEA 10.5 or older releases.
