XpBottle

- Improved compatibility from Minecraft 1.16.5 to 26.3. - Fixed redemption of custom XP bottles. - Fixed items being lost when inventories are partially full. - Includes previous fixes for XP exploits, cooldowns, database saves, and permissions.

This is a major bugfix release. Updating is strongly recommended as it fixes an XP duplication exploit. ## Bug Fixes ### Critical - **XP duplication exploit** — Negative amounts were accepted by the withdraw command (for example `/xpbottle -1000 1`), which gave players free XP instead of removing it. All amounts must now be strictly positive. - **Cooldown never enforced** — The withdraw cooldown was saved but never checked, so it had no effect. It is now applied before every withdrawal, and the waiting message shows the remaining time. - **MySQL settings ignored** — The plugin read `database.mysql.host`, `database.mysql.port`, etc. while the config file defines `database.host`, `database.port`, `database.name`, `database.user` and `database.password`. MySQL connections therefore always used the default values. The correct config keys are now used. ### Major - **Silent data loss in SQL databases** — Saving a player ran a plain `UPDATE` that silently failed when the row did not exist yet. Saves now use an upsert (`ON DUPLICATE KEY UPDATE` for MySQL, `ON CONFLICT DO UPDATE` for SQLite), so no player data is lost anymore. - **Tab completion did not work** — The `TabCompleter` was never registered, so `/xpbottle` had no tab completion. It is now registered (and re-registered on reload) for subcommands, suggested amounts and player names. - **`min-exp` and `max-exp` were never applied** — These config options existed but were never checked. They are now enforced, with dedicated error messages. ### Minor - **Integer overflow** — The total cost (`amount x bottles`) is now computed in 64-bit and rejected if it exceeds the `int` range, preventing corrupted bottles. Redeeming a full stack while sneaking is also computed in 64-bit. - **Invalid sound name** — An invalid sound name in the config no longer causes an error on redeem; the default sound is used as a fallback. - **ItemsAdder fallback** — If the configured `itemsadder_id` item cannot be found, the plugin now falls back cleanly to a vanilla bottle instead of failing. - **Update checker** — A local version newer than the published one is no longer reported as "update available". - **Permissions** — The children of `xpbottle.admin` pointed to non-existent permissions (`xp.admin.*`). They now point to the plugin's real admin permissions (`xpbottle.give`, `xpbottle.take`, `xpbottle.reset`, `xpbottle.reload`). ## Optimizations - **Bottle generation** — Bottles are now created once and distributed as stacks instead of rebuilding the same item N times. This significantly reduces NBT serialization for large withdrawals. - **NBT key caching** — The `NamespacedKey` used to identify XP bottles is cached in the listener instead of being recreated on every interaction and craft check. - **Thread-safe SQL access** — The shared JDBC connection is now protected against simultaneous access from asynchronous tasks, eliminating a corruption risk on SQLite and MySQL. - **Safer reload** — `/xpbottle reload` no longer clears running cooldowns (they can no longer be bypassed by asking for a reload) and keeps the tab completer registered. - **Withdraw sound** — The previously unused `sound.withdraw` config option is now played on withdrawal.

## Corrections and additions - Completing the `/xpbottle help` with the `take` and `reset` commands. - Fixed helper syntax for XP withdrawal and `give` command, with XP per bottle and number of bottles parameters. - Added missing messages to `lang.yml`: player not found, invalid number, negative levels, player-only command, and XP reset confirmations. - Replaced hardcoded player messages with keys loaded from `lang.yml`. - Added a configurable message in `lang.yml` when a translation key is not found. - Updated the `xpbottle command and permission. reset` in `plugin.yml`. - Configurable protection of XP bottles against renaming at the anvil and their use in crafts, while leaving them tradable.
