rbbz: Review Board extension for Bugzilla support
rbbz is a Review Board extension that integrates a Bugzilla user database. It adds an authentication back end, which, when enabled, authenticates against Bugzilla's XMLRPC API instead of the local Review Board database. When active, Review Board's User List web API, used by the UI's autosuggest, also queries Bugzilla.
As described in Review Board's extension installation docs, install rbbz like any other Python package, e.g.
pip install rbbz
In the Review Board admin UI, go to the Extensions page and enable rbbz. You'll then have to go to the Authentication settings and change the Authentication Method to "Bugzilla". A setting for "Bugzilla XMLRPC URL" will appear. Enter the URL to your Bugzilla installation's XMLPRC API, e.g. https://bugzilla.yourdomain/xmlrpc.cgi.
At this point you should be able to log out and log back in with your Bugzilla credentials. Similarly, when you choose people for a review, the autosuggest should return results from the Bugzilla user database.
In order to stay generic, Review Board's User List web API always searches the local database. To provide support for Bugzilla, rbbz overrides a function called early in the User List function in order to send a user-search query to Bugzilla. It then writes the results to the Review Board user table, updating existing entries and creating new ones when needed.
Support for Bugzilla's REST API (as an option, so older Bugzilla systems are still supported).
Caching in User List to avoid always searching the Bugzilla database, if possible.
