RestoreIt

Runs on Minecraft 26.3. While testing it on a real server I found a handful of bugs, some of them nasty, so most of this release is fixes.

Changed

• Built against Paper 26.3 and WorldEdit 7.4. Needs Java 21+ and WorldEdit 7.3+ now; supported servers are Paper 1.21 through 26.3.
• New snapshots are written as Sponge v3 schematics in one folder per arena (snapshots/<arena>/<snapshot>.schem). Snapshots from 1.1.0 keep their old file and still restore.
• Snapshot files are compressed and written off the main thread; restores read the file in the background and only paste on the main thread.
• Arena and snapshot names are limited to letters, numbers, - and _ (max 32).
• The console and command blocks can take snapshots.
• Scheduled restores no longer print two lines to the console every time they run. Turn on debug-mode if you want them logged.
• /ri status shows running restores as well as snapshots being saved.
• Deleting a snapshot that a schedule uses removes that schedule too.
• The startup log is down to a couple of lines.
• /ri arena create explains why it failed (no selection, too big, bad name) and warns when the new arena overlaps another one.
• Removed config options that never did anything: storage.*, performance.batch-size, general.auto-save-interval and advanced.*. An out-of-range value now falls back to its default instead of the middle of the allowed range.

Added

• /ri arena validate <name> checks your selection and the name (it used to say "coming soon").

Fixed

• Deleting an arena with different capitalisation (/ri arena delete duel for Duel) left it in arenas.yml, so it came back after a restart.
• Deleting an arena left its snapshots and schedule behind. A new arena with the same name then inherited them, and restoring pasted the old build into the new spot.
• Restores bigger than batch-size x 1000 blocks (100,000 at the lowest setting) failed partway.
• A restore that took longer than 30 seconds was reported as failed while it was still pasting.
• A refused restore (arena already restoring, too many at once) didn't tell you anything.
• Messages with a name in quotes showed a literal {0} instead of the name.
• Clicking an arena or snapshot in a list ran /arena info or /snapshot info, which don't exist.
• Help text pointed at /arena ... and /snapshot ... instead of /restoreit ....
• Arena snapshot counts in /ri arena list, info and stats were always 0.
• Arena a_b with snapshot c and arena a with snapshot b_c shared one file.
• A name like ../x wrote files outside the plugin folder.
• A snapshot that failed to save blocked that name until the next restart.
• Stopping the server wrote the in-memory config back to disk, undoing any edits made to config.yml while it was running.
• Two snapshots saving at once could lose one of them from snapshots.yml.
• Taking a snapshot of an arena whose world isn't loaded threw an exception instead of saying so.
• /ri version credited "RestoreIt Team".
