1463377 - Migrate blocklist versionRange to JEXL filters

Status: NEW

(Toolkit :: Blocklist Implementation, enhancement, P3)

Description

[Mathieu Leplatre [:leplatrem]]

Once our whole user base will support JEXL (bug 1451031) we can migrate the `versionRange` field to JEXL expressions on the server side, and remove the custom target filtering code from bug 1458920

The only remaining active use of versionRange is the Gfx blocklist, current production data at https://firefox.settings.services.mozilla.com/v1/buckets/blocklists/collections/gfx/records

Previously, it was also used in the plugin blocklist and extension blocklist v2. These are obsolete, however.

In bug 1649872, the Gfx blocklist got support for filter_expression, in Firefox 80 (and uplifted to 79 / ESR78).

Due to the root CA expiration (https://support.mozilla.org/en-US/kb/root-certificate-expiration), the only clients that can fetch new RS records are ESR 115.13+ and Firefox 128+. That means that there are no clients without support for filter_expression.

Would it be a good time to migrate to filter_expression for the Gfx blocklist, and remove the special versionRange logic from the Gfx blocklist?

Thank you for the background and context.

Yes, definitely!
