2.14.0

Released 2015-09-30

Summary: this starts using Windshaft as library (aka version 1.0.0), it no longer extends old Windshaft server.

Announcements:

• Upgrades windshaft to 1.0.0

New features:

• Named tiles: /api/v1/map/named/:name/:layer/:z/:x/:y.:format

Ported from Windshaft pre-library:

• Almost all acceptance tests, some unit and some integration tests
• Stats + profiler

New features:

• Named maps MapConfig provider
• Base controller with: req2params, send response/error mechanisms
• Authentication/Authorization moves to its own API so it can be reused
• Surrogate-Key headers for named maps and affected tables

Improvements:

• No more fake requests to emulate map config instantiations
• As named maps previews are using named map MapConfigProvider it doesn't need to load the MapConfig
• Controllers using Windshaft's backends to request resources through MapConfig providers
• Express 4.x, as Windshaft no longer provides an HTTP server, here we start using latest major version of Express.
• assert.response implemented using request
• All tests validate there are no unexpected keys in Redis and keys requested to be deleted after a test are present
• Test suite in Makefile generated with find
• Image comparison with mapnik.Image.compare
• Doesn't emit Named map update event on unmodified templates

TODO:

• Named map provider checks on every request if named map has changed to reload it (actually reset it so MapConfig has to be regenerated). See f553efa69e. This is done this way because when running the Service in a cluster there is no communication between different instances so when a named map gets updated in one of the them the rest is not aware/notified of the change. In the future there should be a mechanism to synch this changes between instance:

• endpoint
• redis pub/sub
• backdoor

  • Removes TemplateMaps dependency on SignedMaps
  • Token validation is done against the template

    • 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

    • In the future there could be more backends, for instance to invalidate a CDN.

    • 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
