Player duplicates on tab when using redis for cross-server global playerlist

[Dagrond]

Server version

1.21.10

TAB version

5.5.0

Plugin list

Just TAB, I have tested it on clean servers and the issue is still there.

Describe the bug

I have connected 3 servers together using REDIS method, redis is connected successfully on all 3, without TAB bridge. When players are switching servers, there is sometimes a bug which causes duplication issues on tablist.

What I tried:

1. I have tried to switching on and off different config lines, including use-online-uuid-in-tablist, scoreboard-teams, and tablist-name-formatting. Nothing really helps.
2. I'm sure I don't get any errors in errors.log, anti-override.log, or placeholder-errors.log.
3. I have correctly set server-name in each subserver config to a different value, I tested it with %tab_placeholder_server% to make sure they are different on each.
4. No I cannot use proxy mode, as I'm using proxy-as-a-service, so it's not velocity nor bungee. Shouldn't matter as REDIS method is independent from proxy.

Expected behavior

Well, players shouldn't duplicate on tablist. Everything else works pretty well on this config, maybe there are some minor issues with sorting but nothing too crazy.

Steps to reproduce

1. Have 3 separate servers connected with REDIS method, let's say s-1 s-2 and s-3 servers.
2. start with 2 players connected to s-1
3. First player is just sitting on s-1
4. Second player switches server from s-1 to s-2
5. tablist is still working fine for both players
6. now, second player switches server from s-2 to s-3.
7. tablist is correct for second player, but the first (who is sitting on s-1) has duplicate name of second player on tablist. Like he didin't get info that second player disconnected from s-2, but get info that he connected to s-3. /tab reload is not fixing it. First player must change server to fix duplication on its tablist. But it will happen again.
8. When second player switches server back to s-1, one of the entries will change, but the duplicated one persists.

Additional info

Here is some visual explanation after doing reproduce steps from above. Tablist for player "Dagrond" who was switching servers - correct view. (don't mind the lunar client logo, it is client-side)

Tablist for player "Dnorgad" which was sitting all the time on s-1 server:

Now, let "Dagrond" switch server back from s-3 to s-1. One of the entries will get updated, but the second one is still there for "Dnorgad":

Note that I've added tabsuffix for debug purposes, with server names. It is happening without it aswell.

I have empty groups.yml.

Checklist

• I am running latest version of the plugin
• I have read the wiki to make sure it's not an issue with configuration
• I ticked all of the boxes without actually reading them
• I have read the Compatibility wiki page and am not trying to run the plugin on an unsupported server version / platform
• I am willing to cooperate to get this issue resolved faster, including providing any additional information requested or testing new builds

Can you get latest build from https://github.com/NEZNAMY/TAB/actions and run /tab dump <player looking at tablist>, then send the generated link? For some reason, UUIDs did not match, so player was duplicated - I assume one is online and one offline, not sure why. The output should help.

This is done for player that has duplicated entries in scoreboard. Weird that this doesn't show duplicated entries in this dump (or I can't read it properly?) But it clearly is duplicated ingame:

[NEZNAMY]

That is very strange. Can you test it more until you get a dump that shows all 3 entries (on the bottom)?

[Dagrond]

Cannot make it happen to show 3 entries in dump. I'm 90% sure that this is something with packets. Player who sees duplicated entries on tablist, has also duplicated entries in social interactions tab (default P key):

Also vanilla commands are tabcompleting Dagrond even if dagrond is offline in whole proxy (after the duplication happens, client thinks that there is Dagrond on this server, but he is not. Commands from plugins are not tabcompleting dagrond because well he is offline):

[NEZNAMY]

Both social interactions and tabcomplete use the tablist to take values from, that's why.
I will try to look into this and hopefully will come up with something.
