class buildbot.steps.source.svn.SVN

The SVN build step performs a Subversion checkout or update. There are two basic ways of setting up the checkout step, depending upon whether you are using multiple branches or not.

The SVN step should be created with the repourl argument:


(required): this specifies the URL argument that will be given to the svn checkout command. It dictates both where the repository is located and which sub-tree should be extracted. One way to specify the branch is to use Interpolate. For example, if you wanted to check out the trunk repository, you could use repourl=Interpolate("http://svn.example.com/repos/%(src::branch)s"). Alternatively, if you are using a remote Subversion repository which is accessible through HTTP at a URL of http://svn.example.com/repos, and you wanted to check out the trunk/calc sub-tree, you would directly use repourl="http://svn.example.com/repos/trunk/calc" as an argument to your SVN step.

If you are building from multiple branches, then you should create the SVN step with the repourl and provide branch information with Interpolate:

from buildbot.plugins import steps, util


Alternatively, the repourl argument can be used to create the SVN step without Interpolate:

from buildbot.plugins import steps


(optional): if specified, this will be passed to the svn binary with a --username option.


(optional): if specified, this will be passed to the svn binary with a --password option.


(optional): if specified, an array of strings that will be passed as extra arguments to the svn binary.


(optional): specific files or directories to keep between purges, like some build outputs that can be reused between builds.


(optional): Specify depth argument to achieve sparse checkout. Only available if worker has Subversion 1.5 or higher.

If set to empty updates will not pull in any files or subdirectories not already present. If set to files, updates will pull in any files not already present, but not directories. If set to immediates, updates will pull in any files or subdirectories not already present, the new subdirectories will have depth: empty. If set to infinity, updates will pull in any files or subdirectories not already present; the new subdirectories will have depth-infinity. Infinity is equivalent to SVN default update behavior, without specifying any depth argument.


(optional): By default, the got_revision property is set to the repository’s global revision (“Revision” in the svn info output). Set this parameter to True to have it set to the “Last Changed Rev” instead.

mode method

SVN’s incremental mode does not require a method. The full mode has five methods defined:


It removes the working directory for each build then makes full checkout.


This always always purges local changes before updating. This deletes unversioned files and reverts everything that would appear in a svn status --no-ignore. This is equivalent to the old update mode with always_purge.


This is same as fresh except that it deletes all unversioned files generated by svn status.


This first checkout source into source directory then copy the source directory to build directory then performs the build operation in the copied directory. This way we make fresh builds with very less bandwidth to download source. The behavior of source checkout follows exactly same as incremental. It performs all the incremental checkout behavior in source directory.


Similar to method='copy', except using svn export to create build directory so that there are no .svn directories in the build directory.

If you are using branches, you must also make sure your ChangeSource will report the correct branch names.
