PlayerDataSyncReloaded 26.10-ALPHA.001 — Velocity

Alpha build. Compiles and passes the unit tests; not yet exercised on a live network. Test on a staging server first.

Distribution

• Now a separate download. Previously shipped inside the Paper jar as bundled/playerdatasync-velocity.jar.

Added

• Save handshake: ServerPreConnectEvent sends save: to the current server and holds the switch until it answers saved:<uuid>. The destination server can no longer read storage before the previous server's save committed — the cause of "old armor came back" after a switch.
• Config file plugins/playerdatasync/playerdatasync.properties, created on first start:
  • save_ack_timeout_ms (default 2000): how long to wait for the confirmation; 0 = never wait.
• A backend that never answers (older plugin, Fabric, Forge) is only waited on once; afterwards switches from it proceed immediately until it answers again.
• Control messages from backends on pds:sync are consumed by the proxy and no longer forwarded to the client.

Requirements

• Velocity 3.x
• Backends running PlayerDataSyncReloaded 26.10-ALPHA.001 (Paper) for the handshake; older backends still work, just without the wait.
