1780588 - Custom pings with events in them might be sent with reason "startup"

Status: RESOLVED DUPLICATE of bug 1716725

(Data Platform and Tools :: Glean: SDK, defect, P4)

Description

[Chris H-C :chutten]

All pings with events in them are sent at startup with reason "startup" if there are any leftover events from the previous application session.

I'm not sure if this is desired behaviour. It doesn't bother me in my use cases. But what does bother me includes:

• This isn't documented in the Custom Pings docs
• Sending a custom ping at startup with reason "startup" will error if that ping didn't define a reason of "startup"

This bug is for discussing what the desired behaviour is and updating the code and docs and tests to cover it.

Luckily the solution to this was already thought of (currently only implemented in Glean.js, sadly): https://docs.google.com/document/d/1R-tIZYz4Izx8rDB_YUiJXU9Xtk8VcJoF8Pmhggps_GU/edit#heading=h.5x0d5h95i329
