Permission subsystem

To configure access demarcation between multiple products, CodeChecker has it's permission system. Each user can be assigned some permissions, and each action on the server requires a certain permission to be present - otherwise the action will fail.

The username and group values that permissions can be delegated to are retrieved via user credentials. For the permission system to work, authentication must be enabled, otherwise, the unauthenticated guest user will only have the default permissions given.

Different scopes of CodeChecker use different permissions. Currently, permissions can be defined on the server level (system/global permission), or on the product level.

The master superuser (root)

Each CodeChecker server at its first start generates a master superuser (root) access credential which it prints into its standard output:

[WARNING] Server started without 'root.user' present in CONFIG_DIRECTORY!
A NEW superuser credential was generated for the server. This information IS
SAVED, thus subsequent server starts WILL use these credentials. You WILL NOT
get to see the credentials again, so MAKE SURE YOU REMEMBER THIS LOGIN!
The superuser's username is 'AAAAAA' with the password 'aaaa0000'

These credentials can be deleted and new ones can be requested by starting CodeChecker server with the --reset-root flag. The credentials are always randomly generated.

If the server has authentication enabled, the root user will always have access despite of the configured authentication backends' decision, and will automatically have the SUPERUSER permission.

Managing permissions

Global permission manager

  • Server-wide permissions can be edited by clicking Edit global permissions.
  • Product-level permissions can be edited by clicking the edit icon for the product you want to configure the permissions for.

Permissions can be managed on the web interface. From the drop-down, select the permission you want to configure. The two lists show the users and groups known to the system - if a tick is present in its row, the given user or group has the permission directly granted. (Users who only have a certain permission through permission inheritance are not shown with a tick.)

Only the permissions you have rights to manage are shown in the drop-down.

You can edit multiple permissions opening the window only once. Simply tick or un-tick the users/groups you want to give the permission to or revoke from them. Clicking OK will save the changes to the database.

Permission concepts

Each permission has a unique name, such as SUPERUSER or PRODUCT_ADMIN.

Default value

Permissions can either be not granted or granted by default.

If the server is running with authentication – all permissions are default not granted, which means only the users (or LDAP groups) where the permission is explicitly set will have various access rights.

If the server is running without authentication – in this case there are no "users" as everyone is a guest – every permission is automatically granted.

Permission inheritance

Certain permissions automatically imply other permissions, e.g. a PRODUCT_ADMIN is automatically given every product-level permission.

Permissions achieved through inheritance are exempt from the default behaviour mentioned above. If no user has the PRODUCT_ACCESS permission, every user will have it (because it is a default granted permission), despite an existing PRODUCT_ADMIN inheriting the permission.

Permission manager

Permissions have a clear "chain of command" set in CodeChecker. Only a user who has permission A's manager permission can grant or revoke other users' rights to A.

Available permissions

Developer guide: See the API documentation for the list of permissions and which API call requires which permission exactly.

Server-wide (global) permissions


Not granted

The SUPERUSER permission is the highest possible permission available.

Superusers can manage and automatically have every permission in the system.

SUPERUSER is a dangerous permission to grant, as a superuser can immediately change everything on the server, from demoting other superusers to destroying analysis results!


Default Managed by Inherited from

Users with this permission can get information about access controls: which user or group has global permissions or permissions only for specific products. For more information check the CodeChecker cmd permissions command.

Product-level permissions


Not granted

The product administrator is responsible for the management of an individual product. They can edit the product's appearance (displayed name and description) and delegate other product-level permissions to other users.

Product administrators cannot change the URL or the database configuration of the product.

Product admins are automatically given other PRODUCT_ permissions.


Default Managed by Inherited from

The basic permission to access analysis results stored in the product. With this permission, the user can browse analysis results, comment, set review status, etc.


Default Managed by Inherited from

Users need the PRODUCT_STORE permission to store analysis runs and to delete existing analysis runs from the server.


Default Managed by Inherited from

Users need the PRODUCT_VIEW permission to view analysis runs without modifying any properties of the runs.
