SAN RAMON, CA — (Marketwire) — 09/14/11 — WANdisco, a leading provider of Apache Subversion-based software and services for the enterprise, and a major corporate sponsor of the Subversion project today announced what it believes to be the most important enhancements for Subversion users in 1.7. WANdisco staff, including Hyrum Wright, the company-s Director of Open Source and Subversion-s release manager since 2008, along with senior Subversion developers Phillip Martin and Julian Foad made significant contributions to the planning and delivery of this major new release.
“Subversion 1.7 represents a major step forward in addressing the scalability and performance issues encountered by large Subversion deployments, especially those found on the client-side,” said Hyrum Wright, Subversion-s release manager and WANdisco-s Director of Open Source. “The working copy metadata rewrite (WC-NG) and HTTPv2 enhancements were key to this effort.”
Key Subversion 1.7 enhancements include:
HTTPv2 – a protocol rewrite designed to enhance performance between Subversion clients and the server by reducing the number of round trips between the client and the server with every request. Early reviews indicate that performance improves significantly, particularly over high latency networks, as a result of reducing the chattiness of this most widely used Subversion protocol.
WC-NG – a rewrite of the working copy library that enhances performance by centralizing metadata storage so that Subversion operations don-t have to walk the entire directory tree to gather the information about the working copy and apply changes to it. WC-NG also provides a foundation for supporting features such as shelving and offline commits in future releases.
Merge-tracking enhancements – Subversion 1.7 provides over 40 improvements to merge tracking, on top of the improvements that were added in the 1.5.x and 1.6.x series of releases. One of the most significant enhancements has been isolation of subtree mergeinfo updates to only the subtrees affected by a merge, rather than updating all subtree merge info.
WANdisco will be sponsoring a number of additional enhancements to Subversion 1.7-s branching and merging capabilities, including the introduction of the “newmerge” command to be presented on September 28, during the free webinar — — detailed below.
svnrdump – a new client tool that provides the same functionality as svnadmin dump and svnadmin load, but on remote repositories. There-s no need for administrator access to the source or target repository on the remote server.
