We’re big fans of Beanstalk. In fact we like them so much we now host all of our production repositories there.

Beanstalk offers top-notch cloud-based version control with great deployment, integration and collaboration features. It also has one of the best user interfaces.

And that got us thinking: if we could integrate one of the leading repository-hosting platforms with the ultimate Subversion client, Mac users around the world would be in for a treat.

So that’s what we did.

The integration makes it super-easy to start using Beanstalk’s Subversion hosting with Cornerstone. If you already have a Beanstalk account just copy the URL from your repository’s info page and Cornerstone will automatically add the information it needs. All you need to do is provide your account details and you’re done.

To celebrate the new partnership, all Beanstalk account holders receive a 10% discount coupon for Cornerstone. Just log into Beanstalk and either create a new repository or visit the repository help page to get your discount code for use in the Cornerstone web store.

2.7 is a free upgrade for all Cornerstone 2 license holders running Mac OS X 10.6 and 10.7. Please note that 2.7 does not run on Mac OS X 10.5 Leopard.

New Features

1. Compatibility with Subversion 1.7

   Cornerstone 2.7 adds full support for Subversion 1.7, including the ability to connect to 1.7 servers and access 1.7-format repositories.

   2.7 also provides the ability to upgrade a 1.4-, 1.5- or 1.6-format working copy to the new 1.7 format. However, it is not possible to downgrade a 1.7-format working copy (as is the case with older working copies.)

2. Beanstalk Added as a Cloud Service Repository Type

   Zennaware has partnered with Wildbit to integrate support for their Beanstalk Subversion hosting service into Cornerstone. The Add Repository window’s new Beanstalk cloud service greatly simplifies connecting to a Beanstalk-hosted repository.

   The Beanstalk page also provides a Sign Up for a Repository button which enables a user to quickly and easily sign up for a free or trial hosting plan with Beanstalk.

   Beanstalk repositories are displayed in the source list using a specific icon enabling easy differentiation from generic http/https/svn/svn+ssh/file repositories.

3. Improved Support for Certificate-Based Authentication

   Version 2.6 and earlier provided limited support for certificate-based authentication with SSL/TLS servers. This support was substantially improved for Cornerstone 2.7.

   Subversion is traditionally configured to use PKCS#12 certificate files stored at a location in the file system of the user’s choosing. Earlier versions of Cornerstone respected these settings but would not prompt the user for a certificate file or a password if necessary.

   These shortcomings were rectified for 2.7.

   Cornerstone now provides full support for using certificates (and their associated private keys) stored in the Mac OS X keychain. This improves on Subversion’s traditional file-based certificate configuration in a number of ways by providing simpler configuration and greater security.

   Cornerstone 2.7 can be configured (using the new Certificates preference pane) to reference one or more certificates stored in the keychain. Cornerstone can also import PKCS#12 files into the keychain.

   If multiple certificates are configured then Cornerstone will ask for the preferred certificate with the same standard user interface used by Safari and other SSL-aware applications.

   See the Configuring Certificate-Based Authentication article in the Cornerstone help book (Help > Cornerstone Help) for more information.

4. Improved Handling of Invalid SSL Server Certificates

   Cornerstone now uses the standard system-provided user interface for asking the user to accept an untrusted server certificate. Certificates accepted permanently by the user are added to the user’s keychain in the same manner as Safari and other SSL-aware applications.

Performance Improvements

1. HTTP Performance

   Subversion 1.7 introduces a new HTTP-based protocol that promises improved network performance. 1.7-capable client applications such as Cornerstone will automatically use the newer protocol when connecting to a 1.7 server.

   Subversion supports the use of two different client libraries for accessing repositories using the HTTP protocol: Neon and Serf. While the Subversion developers have added support for the newer 1.7 protocol to both these libraries, client applications must use the Serf library to see the maximum performance gains (although Neon users should also see significant performance improvements).

   For maximum compatibility, Cornerstone has traditionally used the Neon HTTP library (the Serf library is missing support for certain HTTP features), and this continues to be the case in 2.7. As a result Cornerstone users will not gain the full performance benefits of the 1.7 HTTP protocol.

2. Log View Filtering Performance

   The time taken to render the contents of the log view after changing the selected filter was reduced by up to 60%, resulting in a significantly more responsive user interface.

Usability Improvements

1. Improved SSH Handling

   Cornerstone’s SSH password prompt handling was improved. This is relevant for working copies checked out using svn+ssh:// that did not include the user’s account name (in the form svn+ssh://user@example.com/repos) in the repository URL.

   In previous versions, Cornerstone would specify the server name (e.g. example.com) as the location when prompting for a password. This was misleading as the user account for which the password was required was not indicated.

   Cornerstone 2.7 now correctly displays the user account that SSH is requesting the password for.

2. Improved Handling of Temporary Credentials

   The way in which Cornerstone manages credentials (usernames, passwords, certificates etc.) was re-written for 2.7. During this process care was taken to enable the user to use Cornerstone without permanently storing their credentials in the keychain or on disk.

   Previous versions of Cornerstone could re-prompt for credentials under certain circumstances. 2.7 improves this behavior by prompting a maximum of once for each working copy or repository in the source list.

3. Multiple Folders are Created as a Single Revision

   In Cornerstone 2.6 and earlier, creating a path of folders (or a folder with “branches”, “tags” and “trunk” sub-folders) in the repository browser resulted in multiple revisions: one for each folder created.

   Cornerstone 2.7 improves on this behavior by creating all folders in a single revision.

Behavioral Changes

1. Certificates Specified in Subversion’s Config Files are Ignored

   Cornerstone 2.7 can only use certificates stored in the keychain. Support for the traditional method of configuring Subversion to use a PKCS#12 file was intentionally removed.

   If you have been using certificate-based authentication in the past then you will need to configure Cornerstone 2.7 to reference the certificate in the keychain.

2. Background Status Checks Fail for Servers with Untrusted Certificates

   Cornerstone no longer automatically accepts untrusted server certificates when performing background status checks to determine repository status displayed in the working copy source list.

   Instead, Cornerstone 2.7 will reject untrusted certificates until accepted by the user as part of an interactive operation.

3. Files Dragged from Finder are Now Copied

   Prior to Cornerstone 2.7, dragging an unversioned file from Finder to a working copy initiated a move operation. This behavior was changed for 2.7 and files are now copied instead.

4. Folder Paths Can’t be Created in 1.4-Format Working Copies

   Cornerstone allows a path of folders to be created by specifying multiple path components in the New Folder window. E.g., specifying “Libraries/Core/JSON” will create “Libraries”, “Core” and “JSON” if they don’t exist.

   Cornerstone 2.7 improves on the existing functionality by combining the creation of all folders into a single revision when performed directly against a repository (there is no difference in behavior for working copies). This improvement was implemented by switching to a newer Subversion API that is only available in 1.5 and above. A side-effect of this change is that creating a path of folders is no longer supported for 1.4-format working copies. Attempting to create a path of folders will result in an error if any of the parent folders do not already exist.

   Cornerstone users with 1.4-format working copies can work around this limitation by:

   • creating each required folder with a separate use of the New Folder command, or
   • upgrading the working copy to 1.5 format or newer.

Compatibility

Cornerstone is compatible with Mac OS X 10.6 Snow Leopard and 10.7 Lion. Note that 2.7 is not compatible with Mac OS X 10.5 Leopard.

Cornerstone 2.7 is fully backwards-compatible with 1.5 and 2.6. All configuration and settings are transparently migrated to version 2.7 when the new version is run for the first time.

It is important to note, however, that Cornerstone 2.6 and older will not be able to access 1.7-format working copies created by Cornerstone 2.7.

Cornerstone’s configuration files are forward-compatible with 1.5, i.e. you can run versions 1.5, 2.0, 2.1, 2.2, 2.5, 2.6 and 2.7 against the same configuration databases in your Application Support/Cornerstone folder.
