1.25.0

Released 2015-01-26

Announcements:

  • No more signed maps (#227 and #238)
    • Splits template maps endpoint into its own controller
    • Removes TemplateMaps dependency on SignedMaps
    • Token validation is done against the template
    • Template is always extended with default values for auth and placeholders
    • MapConfig is extended, in order to validate auth_tokens, with template info:
      • template name
      • template auth
    • No more locks to create, update or delete templates
      • Trusting in redis' hash semantics
      • Some tradeoffs:
        • A client having more templates than allowed by a race condition between limit (HLEN) check and creation (HSET)
        • Updating a template could happen while deleting it, resulting in a new template
        • Templates already instantiated will be accessible through their layergroup so it is possible to continue requesting tiles/grids/etc.
    • Authorisation is now handled by template maps
    • Template instantiation returns new instances with default values if they are missing

New features:

  • Basic layergroup validation on named map creation/update (#196)
  • Add named maps surrogate keys and call invalidation on template modification/deletion (#247)
    • Extends TemplateMaps backend with EventEmitter
      • Emits for create, update and delete templates
    • VarnishHttpCacheBackend will invalidate a varnish instance via HTTP PURGE method
      • In the future there could be more backends, for instance to invalidate a CDN.
    • NamedMapsEntry has the responsibility to generate a cache key for a named map
      • It probably should receive a template/named map instead of owner and template name
    • SurrogateKeysCache is responsible to tag responses with a header
      • It also is responsible for invalidations given an Invalidation Backend
      • In the future it could have several backends so it can invalidates different caches
    • SurrogateKeysCache is subscribed to TemplateMaps events to do the invalidations
