Yes, if a device receives IdentityDeviceListUpdated, it must broadcast standardized DeviceListUpdated to all its peers because only the receiving device knows the peer list.

What happens if the devices are offline? Wondering if there will be an issues in the interim period, between when identity has updated the device list, and when the peers will receive the message to update their device lists for that user.

Might be worth refactoring this function to take array of device IDs &[&str] and send messages in a for loop, to avoid creating tunnelbroker_client for each device when called this in a loop

refactor to use array od device IDs

ownDeviceID -> thisDeviceID

• add comment
• remove obsolete condition

rebase

ifSocketExists -> doesSocketExist

In this case we also want the receiving device to re-send this to all other peers.

Some questions:

1. When you say re-send, do you mean that the receiving device will send the same message type (IdentityDeviceListUpdated) to peers? Or a different message type? (I assume different, since you indicated this message is always sent directly by Identity.)

Nice to see that 👏

• rebase
• shorthand

• address review
• rebase before landing

nice 👏
