Apache CMS: New features for anonymous users

Two new features have recently been added to the CMS, courtesy of David Blevins.  These features are geared towards streamlining the user experience for anonymous users.  The first feature is "Quick Mail", which is the analog of "Quick Commit" but for anonymous users who cannot otherwise commit their changes directly.  Quick Mail, which is enabled by default, will take the immediate submission of an anonymous Edit session and post it directly to the project's dev list, saving several steps that might be hard for a new user to walk through.

The second feature is a natural result of that known as anonymous clones.  In the subsequent mailout from "Quick Mail", there will be an url for committers to use to effectively clone the working copy of the anonymous user who generated the patch.  This makes review and subsequent commit operations much more convenient than directly applying the emailed patch to a local working copy.  In fact it is possible for users to clone a non-anonymous user's working copy, so anyone experiencing chronic problems with their working copy on the CMS can get help from other committers by simply using the "Mail Diff" feature to contact either the dev list or another apache committer with details of their problem.

We have added these features in the hopes this will considerably lower the bar for anonymous users in particular to take advantage of the CMS.  Please let your community know about them!

SVN performance enhancements

Tonight we enabled a pair of Intel X25-M's to serve as l2arc cache for the zfs array which contains all of our svn repositories.  Over the next few hours as these SSD's start serving files from cache, the responsiveness and overall performance of svn on eris (our master US-based server) should be noticably better than it has been lately.

In addition we are planning to install 16GB of extra RAM into eris to improve zfs performance even further, but for now we are hopeful that committers will appreciate the performance we've added tonight.
