Overpass API developpement

[Roland Olbricht <>]

Hello everybody,

on the two public instances, the area regeneration every now and then
fails with a "protocol error". This will be fixed with this patch release
https://dev.overpass-api.de/releases/osm-3s_v0.7.62.3.tar.gz
and offer an improvement in other settings, see below:

What happens in more detail is that a request from the localhost that
does not find resources to run will time out after 30 seconds with a
"protocol error", although it shall timeout rather with a "timeout"
resp. "query rejected" after 15 seconds. This has been a side effect of
keeping localhost out of the rate limiting logic. The fix is to now let
at least after 30 seconds without response let the request honestly tell
that it did not get the requested resources.

There is also a new parameter "--limit-client-zero=(yes|no)" to the
dispatcher that can be set to make the localhost exempt from resource
control or not. If you set it to "no" then requests on localohost will
always pass regardless of the resource situation. This is most likely
what you want to do: either you run a truly local service and have
control over the volume of requests by means of the operating system. Or
you have only very few requests from localhost which represent certain
maintenance tasks like area recreation that shall run anyway. Therefore
it is now the default.

Cheers,

Roland
