The data from Discord does not contain all the attributes that the
cached data has. There may be a slight chance that the interaction data
is more up to date than the cached data or vice versa but more
information tends to trump over this slight chance.
Due to a quirk in InteractionResponse.send_message not returning a
message, all messages sent with an associated View would end up having
no message_id set. When multiple instances of a View are responded to
in a slash command context, this meant that the newest one would
override the storage of the older one. Ultimately leading to the first
view instance causing interaction failures.
Since fetching the original message is an unacceptable solution to the
problem due to incurred requests, the next best thing is to store an
intermediate interaction_id as a stop gap to differentiate between
the multiple instances. This change however, came with its own set of
complications.
Due to the interaction_id being an intermediate stop gap, the
underlying storage of the view store had to be changed to accommodate
the different way of accessing the data. Mainly, the interaction_id
key had to be quick to swap and remove to another key. This solution
attempts to change the interaction_id interim key with
a full fledged message_id key when it receives one if it's possible.
Note that the only way to obtain the interaction_id back from the
component interaction is to retrieve it from the MessageInteraction
data structure. This is because using the interaction_id of the button
press would be a different interaction ID than the one set as an
interim key. As a consequence, this stop gap only works for application
command based interactions. I am not aware of this bug manifesting in
component based interactions.
This patch also fixes a bug with ViewStore.remove_view not working due
to a bug being suppressed by a type: ignore comment. It also removes
the older __verify_integrity helper method since clean-up is already
done through View.stop() or View timeout.
Hopefully in the near future, the `/callback` endpoint will return
actual message data and this stop gap fix will no longer be necessary.
This results in poor ergonomics due to the lack of default generics
for the common case. For most users this ends up in a degraded
experience since the type will resolve to Unknown rather than at the
very least a Client.
This has potential to be a breaking change and Discord could definitely
royally screw this over in the future. However, as far as I can tell
every interaction has either a User or a Member so this change should
be kosher. I'm unaware of any interaction, even in the future, where
this is not true.
I hope these are not my famous last words.
