Digital Touch support

[trymoose]

When researching handwritten messages I found digital touch messages were handled in bluebubbles the same way here and here. Piping them through protoscope gives a valid message but it is different and more complex than the handwritten ones.

Digital Touch is already supported—they are sent as gifs.

Actually this appears to have changed–they no longer get converted by the system. For what it's worth, they aren't supported by macOS either:

They also sometimes seem to not even have the requisite payload:

I've been generating and viewing them on iOS. I don't think I've seen one with a NULL payload before.

Ok, so the one that had a NULL payload used the subject column (the one used for message subject lines) contained a GUID that mapped to an existing Digital Touch message in the conversation:

I've made some progress implementing support for these messages.

• [x] Tap
• [x] Heartbeat
  • [x] Heartbreak
• [x] Kiss
• [x] Sketch
• [x] Fireball
• [ ] Photo
• [ ] Video

Was the NULL message copy and pasted in iMessage?

[ReagentX]

It was not pasted and also does not show up in the thread.

The only other thought I have right now is that it might be related to the announcements that show up saying "person kept a Digital Touch Message from you."

[ReagentX]

Those seem to come from one of the date columns.

[ReagentX]

The NULL Digital Touch messages do not have date_played and also have a custom type of 5, which may indicate the "Kept" status as you mentioned:

Also, they do not always have the subject field populated and contain no typedstream-encoded body data:

They also set this message_action_type field and do not have expiry data:

In my database, an item_type of 5 always correlates with a message_action_type of 2.

[trymoose]

I found some of the NULL payloads in my databases. I saw the database shows they are not delivered but finished:

I had the same item_type of 5 and message_action_type of 2.

[ReagentX]

Yes, I see the finished status too—it also appears for messages sent with full-screen expressives.
