Replication with custom data not possible?

[weskamm]

Describe the bug
I want to setup my own replication server with custom data.
When trying to run nominatim replication --init the code tries to determine the state of the database by calling the openstreetmap API with the highest node id found in the database. This does not work when using custom data (which has node ids that are not contained in the OSM data itself). The code bails out at

Nominatim/src/nominatim_db/db/status.py

Line 52 in e92e03e

node_url = f'https://www.openstreetmap.org/api/0.6/node/{osmid}/1'

with error "Failed to load URL: https://www.openstreetmap.org/api/0.6/node/1000000000017/1"

Are there any options to circumvent this behaviour / supplying a timestamp by ourselves?

To Reproduce
Insert in entry in the db with an osm-id that does not exist

Software Environment (please complete the following information):

• Nominatim version: 4.2, but seems to be the same on current master
• Postgresql version: 14
• Postgis version:
• OS:

There is currently no way to supply an external timestamp. I can see how this could be useful.

If you have a recent version of Nominatim (4.4+) then Nominatim will try to take the date from the osm2pgsql_properties table first. You can set the date there manually to the date you need if no proper date was set when importing the original file. You need to set the current_timestamp property.

Ok thanks, this is a valuable option!
