Configure Teams and Developers¶
By default CodeScene creates a Team and Developer configuration for each new project, but you also have the option to share the settings with other projects. Using a shared configuration is recommended when several projects target the same organization, to avoid having to repeatedly configure the same Teams and Developers.
Access to Team and Developer configuration is based on project configuration access, ie if you have access to configure a project, you will also have access to the Team and Developer configuration used by that project.
The rest of this guide will walk you through the configuration.
Note that when updating from a version without separate team and developer configuration, CodeScene will automatically migrate existing settings (See Team and Developer Migration.)
Important: Run an Initial Analysis Before You Configure Developers¶
CodeScene mines a list of all contributing developers. Note that this list is mined and updated during each analysis for each project using the Team and Developer configuration. That means you need to run one initial analysis before the tool gives you the option to configure developer properties!
Define Your Development Teams¶
Click the Teams tab in your Team and Developer configuration to proceed to the teams configuration, as shown in Fig. 212.
The only thing you have to do is to specify the name of each team in your organization. Later, when you
configure developers, you’ll assign them to the team names you chose here (see
Tip: Some organizations just use one development team. In that case, introduce virtual teams that depend upon the responsibilities of the different developers. For example, you might want to define a Feature team, a Maintenance team and an Infrastructure team. Using this strategy, you’d be able to identify code at risk for incompatible parallel changes since different forces lead to the changes.
Even Open-Source Software Has Teams¶
The team definition is straightforward if you analyze a codebase that’s owned by a traditional organization; Just use the information from your organizational chart. However, we find it interesting to apply teams to open-source codebases as well.
So if you happen to analyze an open-source project, consider introducing the following teams to get additional social information:
Define a teams for the organization that owns the code. For example, if you analyze the Clojure codebase, you’d define Cognitect as one team. If you analyze one of Microsoft’s open-source codebases, you’d use Microsoft as one team.
Define a team for third party developers that contribute to the codebase
Consider defining a team of the core maintainers too.
Configure Developer Properties¶
The developer properties are a bit more tricky than the team configuration, so please let us walk you through them one by one as illustrated in Fig. 213.
CodeScene automatically updates the list of contributing developers; If a new developer starts to contribute code, they’ll be present in the list and the tool lets you configure their properties.
Here are the properties you need to specify:
Active/Ex-Developer: By default, all developers are considered active. If some of them leave your project, mark them as Ex-Developers and CodeScene will include them in the Knowledge Loss Analysis.
Team: The second column lets you assign the developer to a team. This enables CodeScene’s organizational analyses such as the Team Knowledge Distribution Analysis.
Exclude author from analysis: If you check this option, the author will be excluded from all social analyses (although their contributions will still be included in the technical analyses like Hotspots and Code Churn). This is an option you use in case you have roles like System Integrators that only merge code, but never actually make their own contributions.
Once you’ve defined all developer properties you just need to run a new analysis and you’ll get a smorgasbord of interesting social analysis results.
Developers and their Aliases: Mapping Version-Control Names to People¶
Often, over the lifetime of a project, some developers will sign their commits with different names. This can be a source of inaccuracies for CodeScene’s social analysis tools.
To deal with this, CodeScene provides an interface that allows you to specify the version-control names that correspond with real people. In CodeScene, when we talk about a Developer, we mean the real person. Team membership, author exclusion and ex-developer status belong to the developer. Each developer has at least one Alias, which is how they are identified in version control.
For example, a developer named Jane Doe might have several aliases in version control commits: Doe, Jane, janedoe, J. Doe, etc. This interface allows theses aliases all to refer to the same person, which provides more meaningful results in social analyses and unifies the information we have about the developer in question.
To access the interface, click on the Developer identity mapping interface link near the top of the Developers page.
On the left, the interface displays a list of the current developers.
Choose a developer you want to work on. This is the name that you want to keep.
On the right, a new list will appear. Here you can add (merge) or remove (separate) aliases from the developer you selected.
In this example, we might want to merge the aliases “Aaron Bedra & Stuart Sierra” and “Aaron Bedra and Stuart Halloway” with “Aaron Bedra”. After selecting those two aliases, we would click on the Stage changes button. This updates the list of developers on the left. Now we can either make other modifications or click on “Submit” at the top of the window to finalize the operation.
Separating aliases from their developers¶
If we change our minds, we can later separate these aliases from the developer that we assigned them to. To do this, we select the corresponding checkbox and click on Stage changes again.
After clicking on Submit, the aliases we chose to separate will become full-fledged developers. Because these are new identities, group membership, ex-developer status, and exclusion status will be lost. Merging and unmerging an alias is lossy.
You can use the “Filter aliases” box to search for matching aliases. Regular expressions are allowed, with whitespace counting as a logical OR.
Because the Developer is separate from the version control alias, developers can be renamed without changing how they are detected by CodeScene’s analyses. To change a developer’s name, click on that developer in the left column. You will notice an “Edit name” link next to their name in the box on the right.
Automatic alias resolution¶
Often, when a developer changes work environments, they will use slightly different names while keeping the same email address. In these cases, CodeScene can automatically detect aliases that in most cases should be merged together. When you run an analysis, CodeScene provides a warning:
Inside the developer alias interface, when CodeScene has identified merge suggestions, a button is visible that allows all the suggestions to be merged at once:
Clicking on the button will cause all the suggestions to be staged. You will still need to click on “Submit” to save the changes.
CodeScene uses two different criteria for making merge suggestions:
If a developer already has more than one alias, CodeScene will suggest adding more aliases to that developer.
Otherwise, CodeScene chooses the developer with the longest name (excluding names that are actually email addresses).
If you need more control, the suggestions are also visible in the list of developers and will appear when you select a developer.
Import or Export a Definition of Development Teams¶
It may well be impractical to configure each team and developer via the UI, particularly for large organizations. That’s why CodeScene supports importing the team definitions by uploading a csv-file specifying the organization.
You will find the import and export functionality in the Team configuration:
The input file specifies your organization. The file format used is a CSV with two columns: author and team.
