Show My Maps

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

Two ways this plugin could sit on a server doing nothing while looking perfectly healthy. Both are closed.

It no longer goes silent on a fork

Every sweep was scheduled through the per-player scheduler, which is the right one for a region threaded server such as Folia or ShreddedPaper, and which not every fork carries. When that call threw, the plugin stayed loaded, stayed listening, and swept nothing at all. No error to find, no maps to see, and no way to tell that apart from a server that simply has no maps to send.

It now falls back to the main scheduler and says so once in the console. If you run ShreddedPaper, this is the release you want.

/showmymaps tells you whether it is working

"Installed it and nothing changed" has three causes, they need three different fixes, and in game they look identical. The report separates them:

SHOW MY MAPS 1.1.2
  sweeps run:      23
  maps sent:       108
  unresolvable:    0
  players tracked: 1
  Maps are being sent. Anything still blank is the client: install the Fabric mod.

• No sweeps and players online: it is not running, so check the console.
• Sweeps but no maps sent: it is looking and finding nothing. Check showmymaps.see and disabled-worlds.
• Maps sent and still blank: the client half is missing or on a different version.
• unresolvable above zero: another plugin is showing maps this server holds no data for. Nothing on either side can fix those, and now you can see that rather than guess it.

With nobody online it says so instead of reporting a fault, because zeroes then mean nothing is wrong.

Needs showmymaps.status, op by default.

Tested

Against a real Paper 1.21.11 server carrying a stand-in auction house: 54 listings in one double chest, filled a tick after the window opens the way a plugin querying a database does, and the page turned in place with no reopen. All 108 listings across both pages reached the client, and only the first page ever drew blank, for about a second.
