Show My Maps

This is the server plugin, not the mod. It goes in plugins/. Keep using the Fabric mod on your client, and update both together.

This release is mostly server side. If players have told you that maps go blank, or that only maps they have seen before ever show up, this is the one to install.

Fixed: maps went blank after a portal or a death

The most reported symptom, and the plugin was half the cause.

A client throws away every map it knows when its level is rebuilt, which a dimension change and a death both are. This plugin kept a record of which maps it had already sent each player, so as not to push 16 KB again on every pass, and that record was only cleared when the player quit. So for a whole resend-seconds window after any portal or respawn it deliberately sent nothing to a client that now had nothing, and the player saw blank parchment for art they had been looking at seconds earlier. The record is now forgotten on a world change and on a respawn, and a fresh pass runs a second later.

The mod had the matching hole on its side — a map that arrived just before the switch never reached the disk cache either — which is fixed in 1.1.1. Update both halves, or half the bug stays.

Fixed: places maps hide that were never checked

• Item frames and glow frames. An art wall is item frames, and nothing here looked at one. Vanilla only syncs a frame's map as it enters tracking range, so a wall you were already standing at could stay blank.
• Armour stands and display entities. Both are ordinary ways to build a shop front, and neither was ever read.
• Merchant trades. A merchant's offers are not in its inventory — they are their own list — so a villager or wandering trader selling map art showed nothing however long you stared at it.
• Nesting now recurses. A bundle of maps inside a shulker box used to stop at the box.

New switches in config.yml: nearby-displays and merchant-trades, both on by default.

Also

• The sent record no longer grows for as long as a player stays connected, which on a shop server was thousands of ids nobody would look at again.
• debug: true logs every map sent, and every stack naming a map the server cannot resolve. That separates "the plugin is not looking there" from "another plugin drew that map straight to packets and there is no map data behind it" — the one case nothing on either side can fix. Turn it on before reporting a blank preview.

Why beta

The fixes carry regression tests, including one that fails without the dimension-change fix and passes with it. It is marked beta to match the mod it pairs with, whose new art-source feature has had less time in the wild.
