• Fix Signaling messages wrong when conversation is switched #9615
• Fix Alignment of typing indicator behaviour #9624

🏚️ Before	🏡 After

---

After the first key stroke, we send first true signal start to watching after input value, if it was changed within intervals:

• 0-10s: if something else was typed, after 10s from the start we send another true signal;
• 10-20s: if still typing, after 20s from the start we send anothertrue signal;
• ... and repeat for each 10s interval.

In that case, first possible true signal will be received in 0s + delay after actor started typing;
consequent signals will come every 10s + delay.

---

false signal will be received:

• after actor sent message: in 0s + delay;
  false signal will be set locally by client:
• after actor left chat: in 0s;
• after actor stopped typing (input value wasn't changed in 10s interval): in 15-24s;

As typing person

• Send "Typing" every 10 sec when there was a change - done with interval
• Stop on leave room - already done on receiving end
• Stop on send message - the only stop-signal to be sent

As receiver

• Hide user from indicator after not receive "Typing" in the last 15 sec - done with store
• Group sessions by actor type + actor id - should work as-is
• Ignore self - done with store, adjusted in tests

✅ Looks gokd from the screenshot but didnt review the code and didnt test

I haven't tested yet and haven't checked changes in webrtc and tests but there are some blocking comments.

Tested locally and works as described.
Personally it feels a bit long until the indicator disappears, because when you type 2 characters, we are always sending the second "startedTyping" after 10 seconds.

Yes, but this respects #9624

For the record: my force push was with dummy commit and its drop.

GitHub had weird behavior, the new Maksim's commits appeared in the branch but not in the PR o_O

Thank you for your great work!

I checked the behavior:
When deleting, the typing indicator appears and disappears after a +10s delay. I also think that having a delay of >10s is a bit long. Maybe we should consider reducing it.

I think, users usually type for a longer time, so 10-25s doesn't usually looks as long as in this video.

Thought, it would be good if we have some way to change those values: #9717

Adding a small delay may also help with the situation on the video, then a user suddenly typed some symbols for a second: #9718

What about the typing indicator when the user is deleting the text, is it considered accurate?

Yes, erasing a text is also considered as typing
