Deprecate / remove Wiki template handling #496

Open mmd-osm opened 6 years ago

mmd-osm commented 6 years ago

http://overpass-api.de/template_handling.html is a quite dated concept and never really took off. These days, the fetch + show operation indicate that it's also no longer working on the productive servers.

Can we deprecate this approach and remove it from Overpass API?

There has just been somebody using the feature and reporting the problem.

I guess it's about this template then: https://wiki.openstreetmap.org/wiki/Template:Overpass-base?

IMHO the concept of having a user triggering a "fetch" operation is not really ideal, as it leads to a "user state" on the server. While this worked for a single production server, it's getting unpredictable with two production machines. And using the single host names z. or lz. is also something a don't want to recommend.

If this concept should still be in place, this Wiki template loading should be done automatically behind the scenes, so that the action=fetch should become a no-op.
