Integrating with Subversion

Subversion (also known as SVN) is a Software Configuration Management (SCM) system, that enables users to work on code simultaneously while preserving previous versions by avoiding collisions in code edits. While users working on the code will usually have a complete copy of the repository on their local systems, this plug-in will access the repository remotely by use of the "svn://" , "http://" and "https://" protocols. (Note that "svn+ssh://" may be supported on a server by server basis.)

Due to the methodologies in which IIS handles web requests and runs on the server, any SSH connection certificates that have trust issues will be automatically accepted. Therefore, we recommend using an IP address to connect to the server instead of a DNS name that could be redirected to an unsafe connection.

The current version of the Subversion plugin requires SpiraPlan or SpiraTeam v5.4.0.0 or later.

Installing the Subversion Plug-In To install the Subversion Version Control plug-in, follow these steps:

  • Copy the following files into place on your Web Server's SpiraTeam installation:

  • Copy the file "SubversionProvider.dll" file into the "VersionControl" sub-folder of the SpiraTeam installation.

  • If your server operating system is 64-bit, then copy all the files in the "x64" directory of the downloaded plug-in zip file into the "VersionControl" sub-folder of the SpiraTeam installation. Note: Do not create an x64 folder under VersionControl, make sure the files live in the VersionControl folder itself.

  • If your server operating system is 32-bit, then copy all the files in the "x32" directory of the downloaded plug-in zip file into the "VersionControl" sub-folder of the SpiraTeam installation. Note: Do not create an x32 folder under VersionControl, make sure the files live in the VersionControl folder itself.

  • Log in as the Administrator and go into SpiraTeam main Administration page and click on the "Version Control" link under System.

  • Click the "Add" button to enter the Plug-in details page. The fields required are as follows:

  • Name: The name must be "SubversionProvider".

  • Description: The description is for your use only, and does not affect operation of the plug-in.

  • Active: If checked, the plug-in is active and able to be used for any project.

  • Connection Info: This field holds the root of the repository for any project accessing the plug-in, unless overridden in the Project Settings. Start the connection string with svn://, http://, or https://.

  • Login / Password: The user id and the password of the user to use while accessing and retrieving information from the Subversion server.

  • Custom 01: This field is used for debugging. Please leave it blank unless specified by support.

  • Custom 02-04: These three fields are used to specify the standard Subversion layout, where there are specific folders for the Trunk, Branches and Tags:

If you want to use the Branches feature in SpiraTeam, you need to populate all three fields:

  • Custom 02: The folder containing the Trunk (usually called Trunk or trunk)

  • Custom 03: The folder containing the Branches (usually called Branches or branches)

  • Custom 04: The folder containing the Tags (usually called Tags or tags)

  • Other Fields: The other fields (Domain, Custom 05) are not used by the plug-in and will be ignored.

  • When finished, click the "Insert" button and you will be taken back to the Version Control integration list page, with SubversionProvider listed as an available plug-in.

  • Verify that you are in the correct project using the drop-down at top, and click on the "Project Settings" link for the SubversionProvider. You will get a screen listing all the same configuration settings:

  • Be sure to change the Active field to Yes, or the repository will not be available for the current project.

  • Any other settings entered on this page will override - and have the same use as - the general settings that you created above. You would use these settings if you will have more than one project access different code repositories.

  • Initial setup is complete, click on the "Source Code" menu under the Tracking tab to navigate and browse the source code repository.

Using Subversion with SpiraTeam

While being able to browse the source code repository can be useful in itself, the real strength comes from linking artifacts in SpiraTeam - including Incidents, Requirements, and Tasks - to revisions checked into the software repository.

Viewing the Repository Tree

View the source code tree by selecting the "Source Code" link under the Tracking tab. You will get a screen similar to:

This means that SpiraTeam is making the initial connection to Subversion and building its local cache. Once it has finished building the cache, you'll see a screen that looks like:

The folder tree of the repository is on the left, and files in the current selected directory will be listed in the right table. The file view will display the filename, the current revision number of the file and the date of the last commit. You can filter and sort on any of the columns, as well.

The page will display the folders and files for the currently selected branch (in the example above "Trunk"), you can change the current branch at any time by selecting it from the dropdown menu:

If you click on the Clone or Checkout button, SpiraTeam will display the URL you should use for connecting to Subversion using your SVN client:

Viewing File Details

To view the file details, click on a file in the right-hand side of the repository. The file details page displays the details on the selected revision. By default, it will be the HEAD revision, unless you clicked to view the file details from a revision. By clicking on the file name, you can download the specified revision of the file to your local machine. This does not do an SVN checkout; you are merely downloading the file to your local machine.

Underneath the file details are tabs that show a preview of the file (with syntax highlighting), a list of all the revisions that this file belongs in, or was committed to, who performed the commit, and the log message for the commit, and a tab that shows any artifact associations. Throughout SpiraTeam, revisions are indicated by the Revision

icon:

Revision Details

By clicking on a revision in SpiraTeam, you will be taken to the revision details page.

The revision details screen shows the log for the Commit, the commit date and author. At the bottom of the page are two tabs, Files and Associations. The Files tab lists all files that were a part of this commit, with their full path and the action that was performed on them for this commit. Possible values are Added, Modified, or Deleted.

The Associations tab shows any artifact (Incident, Task, Requirement, Test Case, Test Set, etc.) that the log message references. See Linking Artifacts for information on how to link a revision with a Subversion Commit:

Linking Artifacts

Linking an artifact is quite simple. To maintain the readability of Subversion's commit messages, we adopted a bracket token. The token is in the format of:

[<artifact identifier>:<artifact id>]

The first half, the Artifact Identifier, is a two-letter code that is used throughout SpiraTeam, and is visible on almost every page in the application. For example, a requirement's identifier is "RQ". Incidents are "IN", and test cases are "TC". The artifact ID is the number of the artifact. So by creating a commit message that reads:

SpiraTeam will automatically detect tokens and will include links to them under the Associations tab for a revision detail. If you forget to add the association during the commit, you can use the 'Add Association' option within SpiraTeam to add the association after the fact.

Troubleshooting

While integration with Subversion is rather complex, as a user you will only receive a couple of errors that will prevent the integration from working:

  • SpiraTeam will not display the login page, and there is an error

    (either on the page or in the Application Event Log) that says "Could not load file or assembly." Subversion control and library files come in both 32-bit and 64-bit ("Win32" or "x64") versions. If this error occurs, it is most likely that the wrong version of the files were installed. Download the correct version from the Inflectra website, and overwrite the files in the VersionControl folder.

  • SpiraTeam reports that the login information is incorrect. In this

    case, double check the Version Control settings, both for the Project (which overrides the general settings) and the general settings. Project settings will over-ride the general settings. Be sure to use a user that has access to all nodes in the tree starting from the root repository location.

  • If you are taken back to the repository screen and given a message

    saying that the requested file was deleted from the system, this means that an attempt was made to view details on a file that is no longer part of the HEAD revision. This can happen when a file is deleted or renamed, and this is a normal condition in the code repository, not necessarily an error with Subversion or SpiraTeam.
