Payload for server owned interfaces missing the timestamp
sorru94 opened this issue · comments
The timestamp seems missing in the payload for a publish on a server-owned interface.
This has been observed in the end-to-end tests for the Astarte device SDK python.
Report from this run could be helpful. The interface org.astarte-platform.python.e2etest.ServerDatastream
contains half of the endpoints with explicit_timestamp
set to true
and half with it set to false
.
I think the actual underlying issue is that we're accepting explicit_timestamp
for server-owned interfaces while there's no actual way of sending an explicit timestamp to them from AppEngine API.
explicit_timestamp
was designed to provide devices a way to provide an application-specific timestamp to attach to a piece of data, which could possibly be different from the clock timestamp. Does this make sense for server-owned interfaces too? It's open to discussion, but since in the current state there's no actual way to send explicit timestamps for them, I'd suggest to refute explicit_timestamp
on server-owned interfaces so we don't provide false hopes to the users. We can always start accepting it if and when we actually have support for it.
