Parent page: Version Control and Design Repositories

The best way of working from a known set of source files is to store the design project in a controlled environment, such as a Version Control repository. This is important because the only way of ensuring the outputs come from the correct source files is to:

1. Confirm that the source file set is up-to-date.
2. Take a snapshot of them.
3. Generate outputs from that snapshot.

In Altium NEXUS, such a repository is referred to as a Design Repository. Owned by the design team, the Design Repository contains a high-resolution view of the history of the design process and is the primary collaboration tool used by the design team.

The Design Repository becomes the central repository from which multiple team members can check data in and out, all the while maintaining a complete revision history of all changes made to the design. A design is therefore stored as a series of versions of its constituent project and source documents, building a progressive picture of the intent of a designer over time. By using a version-controlled Design Repository, you have the integral assurance that no revision of a design is ever lost, allowing for safe collaboration on the same design between members of a team that can be geographically dispersed in their locations. The very nature of the version control system provides an audit trail for the design. Full accountability arises through transparency of whom changed what, in which source document, and when. The system can support multiple version-controlled Design Repositories with the link to a particular repository being established by the version control link within the project folder.

Supported Version Control

Related pages: Version Control and Design Repositories, Using Version Control

The version control software – used to implement the repositories themselves – is supported in the following ways:

• Through Altium NEXUS – using the software's built-in support for Subversion (SVN). Enabled for use by default, Subversion capabilities are delivered through the VCS Provider – SVN extension. This extension is installed by default, and delivers version control functionality, through the use of SharpSVN. This implementation has full support for Unicode (multi-byte) characters in file names. This, for example, allows you to add files to your SVN VCS repository that include Russian characters in their names. You are also able to hook up and use an existing Git repository, support for which is delivered through the VCS Provider – Git extension.
• Through an Altium 365 NEXUS Workspace – when you are connected to a Workspace you are provided with localized (and centralized) version control, courtesy of the Workspace's single Git-based design repository – Versioned Storage – for accommodating all of your managed design projects.
• Through the integral NEXUS Server – when you are signed into the NEXUS Server (an integral part of the Altium NEXUS solution) you are provided with localized (and centralized) version control, courtesy of the server's Local Version Control Service. The integral server in a newly-deployed instance of Altium NEXUS provides a single Git-based design repository – Versioned Storage – for accommodating all of your managed design projects.

Managing Design Repositories

Design Repositories are managed on the Data Management – Design Repositories page of the Preferences dialog. From this page, you can perform a number of actions, including:

• Creating new file-based SVN repositories using version control capabilities built-in to Altium NEXUS.
• Connecting to existing SVN repositories.
• Browsing repositories shared for use through the local Version Control service of the managed content server to which you are actively signed in.
• Controlling the active state of each defined repository.

The Data Management – Design Repositories page – command-central for managing VCS-based Design Repositories within Altium NEXUS. The image shows connection to the default Git-based repository (Versioned Storage) available when signed into the NEXUS Server (the server that is integral to your deployed Altium NEXUS solution).

For each registered, or rather connected repository, the following information is presented:

• Name – a meaningful name for the repository. This could, for example, reflect the design projects that are stored in the repository. This name is used elsewhere in the software for quick selection of a Design Repository to be used, for example when opening a project from version control.

• Activated – whether the repository is available for use by the system (enabled) or not (disabled). A newly created or connected repository will be activated by default.

• Type – the type of repository; SVN or Git.

• Repository – the URL to the root folder of the repository.
• Status – whether the connection between Altium NEXUS and the repository is successful () or not (). If connection is unsuccessful a comment will be displayed, indicating the problem.

Creating a New Repository through Altium NEXUS

Creation of new Design Repositories from within Altium NEXUS is performed from the Data Management – Design Repositories page of the Preferences dialog. Click the  button and choose SVN from the associated drop-down menu. The Create SVN Design Repository dialog will appear. Use this to give the repository a meaningful name, specify a default checkout path, and specify the location for the repository. If a folder is specified that does not currently exist, it will be created for you.

With all settings specified as required, click OK. The repository will be created at the nominated location and a connection to that repository from Altium NEXUS made. An entry will appear for it in the listing of Design Repositories back on the Data Management – Design Repositories page of the Preferences dialog.

Creating a Repository through the Altium NEXUS Server

Related page: Altium NEXUS Server – Local Version Control Service

When using a NEXUS Server as your managed content server, and if applicable, SVN repositories can be created through the server's local Version Control service, or external repositories (SVN or Git) can be connected to. Together, all repositories are centrally managed through the VCS page (Admin – VCS) of the server's browser interface.

To add a Design Repository, click the  button, located at the top-right of the page. The Add Repository window will appear, use this to define the repository.

The properties required depend on whether you are creating a new repository using the local VCS service, or linking to an existing, external repository:

• New – give the repository a name and a description.
• Existing – in addition to a name and description, you need to supply the URL to the repository, and your credentials (User Name, Password) to access that repository (if required).

Create a new SVN-based Design Repository through the NEXUS Server's local Version Control service, or link to an existing repository (SVN or Git) that has been created external to the NEXUS Server.

A linked, external Design Repository is distinguished in the list of repositories by its External property being ticked ().

Design Repositories defined through the Altium NEXUS Server are populated to the client automatically during sign-in, so users do not have to worry about URLs, protocols, passwords, etc. A repository is configured once, on the server, and shared with the intended users as required.

Centrally define access to your organization's Design Repositories. SVN-based repositories can be internal to the NEXUS Server installation (defined using the local Version Control service), or external through use of Altium NEXUS's built-in SVN, or third party SVN or Git service. Access control is performed through the VCS page of the NEXUS Server's browser interface. When a user signs in to the NEXUS Server, the Design Repositories available to them will automatically be added to the Data Management – Design Repositories page of the Preferences dialog. In the image above, a user is accessing the server from a different PC, and so localhost is replaced with the name of the PC on which the server is installed (sam in this case).

Connecting to an Existing SVN Repository through Altium NEXUS

In a collaborative environment, one or more Design Repositories may already have been created in a location accessible by multiple users. In this case, you do not need to create a new repository – re-inventing the wheel as it were – rather you simply need to connect to the required existing repository. This is also the case if you have removed a repository from your list of repositories, and want to add it back in again.

To connect to an existing repository, on the Data Management – Design Repositories page of the Preferences dialog click on the  button and choose SVN from the associated drop-down menu. The SVN Design Repository dialog will appear. Enter a name by which to refer to the repository from within Altium NEXUS, specify a default checkout path, and specify the repository access method and path to the root folder of the repository. You can also specify a particular sub-folder within the repository.

With all settings specified as required, click OK – a connection will be made and the repository will be ready for use.

Connecting to an existing repository – in this case a local repository on the hard drive.

Connecting to an existing repository – in this case a repository internal to a server installation.

Connecting to an Existing Git Repository through Altium NEXUS

The Data Management – Design Repositories page of the Preferences dialog offers no controls for creating a new Git repository, or connecting to an existing one. However, you can effectively connect to an existing repository of this type by other means (that are the traditional technique favored by the Git user-ship). To do so:

1. Create your remote Git repository, or access your company's external repository – in which your Altium NEXUS projects are stored.
2. Clone the repository to make your local working Git repository.
3. Open an Altium NEXUS project from the local repository.

Altium NEXUS will recognize that the project is under version control in a Git-based repository, and provide VCS-related statuses, and commands/ functions to work with the files (including Commit (to local working Git repository) and Push (from local Git repository to remote Git repository)).

Editing Repository Properties

You can also edit the properties of a Design Repository at any time. For example, you might want to change the name of the repository, as displayed and referenced within Altium NEXUS. Or you might want to edit the connection, perhaps to link to a different repository. To do this, select the entry for the repository in the listing of repositories (on the Data Management – Design Repositories page of the Preferences dialog), then click on the  button. The SVN Design Repository dialog (or Git Repository dialog) will appear, from where you can make changes as required.

Disconnecting from a Repository

To disconnect from a Design Repository, select its entry in the list and click the  button. The repository is removed from the list of connected Design Repositories. The repository itself is not deleted, it simply becomes disconnected from the system. To use a repository again, connect to it.

Using Design Repositories

Once defined, the connected nature of a VCS-based Design Repository simplifies the ability to either add a project to that repository, or open an existing project from that repository. Instead of having to remember the path or drill down in a browse menu to select the repository, you simply choose the required repository from a convenient listing of all Design Repositories you are currently connected to, and that are activated for use.

Adding a Local Project to a Repository

Adding a Local design project (not currently under version control) to a Design Repository is a straightforward process. With the project open, use the Add Project Folder To Version Control command from either the Projects panel or Storage Manager panel. The Add to Version Control dialog will appear. The field at the top of this dialog presents a drop-down listing of all connected and activated Design Repositories. Select the repository required.

Click the  button to quickly access the Data Management – Design Repositories page of the Preferences dialog – if you need to connect a different SVN repository, or create a new one.

The folder hierarchy within the chosen Design Repository is presented to you in the Folders region of the dialog. Either specify an existing folder into which to add the design files, or create a new folder using the New Folder button. In the latter case, a folder will be added at the specified position within the repository's folder hierarchy, named after the source folder containing the project.

Adding a Local design project to a local design repository. Local design projects may be added to a design repository available through a managed content server in the same manner.

Creating a New Version-controlled Project

When creating a new Version-controlled project, the Repository field in the Create Project dialog presents a drop-down listing of all connected and activated Design Repositories. Select the repository required.

Creating a new Version-controlled design project – all defined Design Repositories are available for use. Shown here is the situation when not signed into a managed content server.

And shown here is the situation when signed into a managed content server – all of that server's Design Repositories are additionally available, with the exception of the Versioned Storage repository.

Adding a Managed Project to a Design Repository

Related page: Management of Projects

Whether creating a new managed project, or making an unmanaged project (Local or Version-controlled) available to a managed content server, the resulting project is stored in a Design Repository. As part of the respective interface used to create/make available, the repository can quickly be selected from a list of defined repositories.

Creating a new managed design project directly within the managed content server to which you are actively signed in. Only design repositories provided by your managed content server (and that are shared with you where applicable) will be available for use.

Opening a Version-controlled Project from a Design Repository

Equally straightforward is the ability to open a Version-controlled design project that resides in a Design Repository. Use the File » Checkout command – the Check Out dialog will appear. Use the Check out from field to choose the required repository from a drop-down listing of all connected and activated Design Repositories.

Click the  button to quickly access the Data Management – Design Repositories page of the Preferences dialog – if you need to connect a different repository.

The folder hierarchy within the chosen Design Repository is presented to you in the Folders region of the dialog. Use this region to specify the exact folder that is to be checked out from the repository.

Use the Check out to field to specify where the nominated folder content is to be checked out to. This is your local sandbox area.

Opening a Managed Project from a Design Repository

To work on a managed project – essentially checking out as a local working copy – first ensure that you are signed into the managed content server in which the project resides. Then use the File » Open Project command. The Open Project dialog will appear. The server will appear in the Locations region of the dialog, distinguished by the  icon, and appearing with the name given to that server. Click on this entry to list the managed projects therein. Only those managed projects that have been shared with you (you have permission to access) will be listed, and from across all managed Design Repositories shared with you. Choose which managed project to open from the server and click . Once opened, the project will appear under an entry for your server, in the Projects panel.

Choose which managed project to open, from those currently shared with you.

You have the option to open the project to the default checkout path, or use the  drop down menu to specify a custom path. The default checkout path is taken from the Document Path field on the System – Default Locations page of the Preferences dialog.
