Subversion 1.6 Released

The fine folks from subversion.tigris.org have bequeathed to the world Subversion 1.6. Grab the source from Tigris or download one of the certified binaries from CollabNet. Subversion 1.6 introduces several new features, including improved authentication and filesystem storage as well as better handling of tree conflicts. Read the full release notes.

Subversion 1.6 and Tree Conflicts

Most Subversion users are familiar with text conflicts. The classic case: You have a locally edited file in your working copy, an "svn update" brings a change to the same file from the repository, that incoming change cannot be merged cleanly into your local change, and the result is a text conflict. Subversion 1.6.0 expands this concept to cover conflicts at the directory level, e.g. you locally delete a file then an update tries to bring a text change down on that file. These new types of conflicts are called tree conflicts.

Blog Roundup on Subversion 1.6

Jeremy Whitlock updated his article on Subversion + Apache and LDAP to reflect changes in all three pieces. He writes, "...changes in the LDAP modules and their respective configuration directives has left my previous entry very confusing for those wanting to use Apache 2.2.x. The purpose of the Definitive Guide is to provide a single location for questions for Apache 2.0.x and 2.2.x, while also providing more depth about things to consider when building your Apache-based Subversion server using LDAP for authentication." C. Michael Pilato added a post about Sparse Directories: "I dig organization. I tend to keep a pretty neat home directory. But I routinely work on several different pieces of software, and at any given time, I'm tracking several different development branches in each of those pieces of software. Were I not using sparse directories, my "projects" directory would look..." rather unwieldy. To round up the SVN 1.6 blogging, Hyrum Wright wrote a post on Packing FSFS Repositories: "For every commit to a FSFS repository, Subversion creates a single file which describes all the changes in that revision. Prior to 1.5, all of those files were stored in a single directory, which had several drawbacks... With sharding, these revision files were split into separate subdirectories, eliminating a large number of these problems."

OCN Tops 200,000 Members

It's hard to imagine now, but when I first started working on openCollabNet in May of last year, we had perhaps 30,000 members. In that brief time, we've pushed the membership to over 200,000. It's wonderful to have the privilege to work with such a dynamic group of people. But there are lots of ways we can improve, too.

Government 2.0 Camp

Guy Martin, a community manager in CollabNet services, wrote about his experience participating in Government 2.0 Camp in Washington, DC. This was an "un-conference" format in which Guy was both a speaker and an active participant berating other speakers (I joke). Highlights include a session on "how governments could deal with outward-facing social media tools, and what policies they should have in place to deal with 'bad' content... Allowing social media in government... spaces is not a big deal if you have some sane procedures in place to deal with the occasional unprofessional comment/content." Note the operative word "sane."

Robot Roll Call - FIRST Robotics Competition

We are proud to announce that we have donated nearly $250,000 worth of licenses for CollabNet SourceForge Enterprise ALM software to enable FIRST Robotics competitors to develop and share the software that drives their entries. FIRST (For Inspiration and Recognition of Science and Technology) is a not-for-profit organization founded by inventor Dean Kamen to inspire young people's interest and participation in science and technology.
