displaynames do not update

[dkg]

• Delta Chat version: 1.46.6

I was trying to replicate deltachat/deltachat-android#3155 and deltachat/interface#71 with a colleague using iOS, and found that my updated displayname didn't show up on their device.

I would have expected it to show up for them, the way it did on Desktop and Android. But it did not. my displayname for them remains "dkg".

Conversely, when they change their displayname, i can see the updated display name on both Android and Desktop systems.

A quick workaround is to go to the user's profile (1. Go to the chat. 2. press their profile-icon. 3. Edit) and remove the name. Afterwards the display name should be updated automatically again if the other user changes their name.

same issue appears on desktop: deltachat/deltachat-desktop#4045

and i just tested on android, this does not work as well. there might have been a degradation recently, i am pretty sure, that used to work.

to reproduce, eg. Desktop to Android:

1. create fresh (!) profile with name "Alice" on Desktop
2. create fresh (!) profile with name "Bob" on Android
3. let Bob scan Alice's QR code
4. for Alice, at "Settings / Edit Profile / Your Name" change to "AliceTwo"
5. send a message from Alice to Bob

=> Bob still shows the old name. this is not a refresh issue, even after restart, get_Bob does receive the new name, but it is not returned by dc_contact_get_display_name().

(we could write a test for that)

still, it was received, as dc_contact_get_auth_name() is correct, see the following "edit name" dialog saying 'enter a name to be shown instead of "AliceTwo"'.

maybe, somewhere on initial receiving a copy of the "auth name" is written to the "edited name" where it should not have been.

tested using desktop1.47.0(core1.147.1) and android 1.48.1(core1.148.4)

Reproduced it with a Rust test, the contact name comes from QR code. The reason is 3f9242a (see Origin::UnhandledQrScan). Seems this was just hidden over years and appeared because of some recent changes. EDIT: I can't get why Origin::UnhandledQrScan mustn't bring the name from QR code to authname and puts it into name instead. CC @link2xt

EDIT:

// from the QR-code scan (potentially from the address book of their other phone), then name

-- so, basically it's because QR codes are generated not only by Delta Chat.
