Subversion Repository

Boost uses  Subversion to manage all of the data associated with Boost's development, including the source code to Boost, documentation for Boost libraries, and the Boost web site.

Accessing the Boost Subversion Repository

The Subversion repository can be accessed in several ways:

svn co  http://svn.boost.org/svn/boost/trunk boost-trunk

svn co  https://svn.boost.org/svn/boost/trunk boost-trunk

For information about gaining developer access to the Boost Subversion repository, see below.

  • On Windows,  TortoiseSVN provides an easy-to-use, graphical interface to Subversion.

Organization of the Boost Subversion Repository

The Boost Subversion repository is organized into several top-level directories, reflecting various stages of Boost library development and subtasks within the Boost community. We have the following top-level directories:

  • trunk: Contains the latest "development" version of Boost.
  • sandbox: Contains libraries and tools that are under active development and have not yet been reviewed or accepted into Boost. See BoostSandbox for information about organization of the sandbox.
  • website: Contains the upcoming Boost web site, which is not yet live.
  • branches: Contains various branches of Boost libraries, typically for release branches and for non-trivial changes to Boost libraries that need to be made separately from the trunk.
  • tags: Contains "tags" that mark certain points in the source tree, such as particular Boost releases.

Developer Access to Subversion

Boost contributors are given read/write access to the Boost Subversion repository when their Boost tasks warrant. There are three different areas of the Boost Subversion repository that contributors may need access to:

  • The main Boost development areas, particularly the trunk directory tree. This level of access is typically restricted to authors and maintainers of Boost libraries.
  • The sandbox area, which is used to develop new libraries and tools that have not yet come up for Boost review. This level of access is available to contributors who want to develop future Boost libraries and collaborate with other Boost contributors.
  • The web site, which stores the Boost web site.

To gain developer access to the Boost Subversion repository, please send a email to the Boost Moderators at boost-owner -at- lists.boost.org stating why you need write access to the Boost Subversion repository, and which parts of the repository--boost itself, the sandbox, or the web site--you need access to. If you had access to Boost CVS when it was hosted at SourceForge, please provide your SourceForge user ID. Once a moderator has approved you for access to the Subversion repository, you will receive an invitation via e-mail that asks you to provide a user name and a password, which will be used to access both the Boost Subversion repository and the Boost Trac. You will also be asked to grant permission for your past and future Boost contributions to be licensed under the Boost Software License version 1.0 and future versions: your permission is required to work with the Boost Subversion repository, so that we can ensure that Boost code is licensed under the Boost Software License.

Please be sure to read the section on MIME types and end-of-line styles, below, and adjust your Subversion configuration as necessary.

Once you have write access to Subversion, you may want to "upgrade" your anonymous checkouts to developer checkouts. You can do so with the  svn switch command, run from your Subversion checkout:

svn switch --relocate  http://svn.boost.org/svn/boost  https://svn.boost.org/svn/boost --username your-username

Alternatively, to get a fresh check out:

svn co  https://svn.boost.org/svn/boost/trunk boost-trunk --username your-username

MIME Types and End-Of-Line Styles

By default, Subversion treats all files as binary. Thus, a text file checked into Subversion with Unix line endings would retain those Unix line endings even when checked out on a Windows or Mac machine. A text file edited on several machines using different platforms would likely end up with inconsistent line endings, causing problems with various development tools. To address this problem, Boost adopts an approach using  `svn:eol-style` properties to provide native line endings for users on all platforms. Each text file in the Boost Subversion repository must have its MIME type set appropriately. For each file with a "text/" MIME type, the file must also have the svn:eol-style property set to native. When thesvn:eol-style is native, the Subversion server stores the file using Unix line endings, but the Subversion client will translate between the server's end-of-line format and the client's native end-of-line format. These settings will be verified by the Subversion repository itself, to keep the repository consistent. Specifically, the Subversion repository will reject commits that contain any files without the svn:mime-type property set or any text files without the svn:eol-style property set.

To automatically maintain correct MIME types and end-of-line styles, you will need to modify your Subversion configuration to use the "auto-props" feature. When you edit your Subversion configuration, remove the existing enable-auto-props = no setting, if it exists, and then add the following text to enable Subversion's auto-properties. The location of the Subversion configuration differs from one platform to the next:

  • On Unix: Edit the file ~/.subversion/config.
  • With the command-line Subversion on Windows: Edit the file %APPDATA%\Subversion\config.
  • With  TortoiseSVN on Windows: Right-click in Windows Explorer to bring up the context menu, and select !TortoiseSVN->Settings. In the "General" configuration tab, click the Edit button to the right of "Subversion configuration file". Now, paste the contents below into that editor window and save the results. Note: If !TortoiseSVN loads Notepad to edit your configuration file, it will save it as config.txt, rather than config. You will need to navigate to %APPDATA%\Subversion\ and rename config.txt to config. Otherwise, auto-properties will not work. Alternately, use the Notepad "Save As" dialog on the file menu, changing the "Save as type" to "All Files", and adding a period after the "config" File name. Then click the "Save" button.
