Where did you go?
Update from January 31, 2021:
I am restarting this project very soon. I saw several forks updating the project thru 1.14 (the version that breaks the plugin).
I will start officially restart maintaining this plugin again before 1.17 get released.
Want to contribute and update the plugin now? PR in GitHub!

17w47a Snapshot Concerns
In the latest snapshot, Mojang introduced a feature to allow any chests to be placed adjacent to each other. This may cause issue in the further Minecraft versions (1.13+). I will remove this warning as soon as the problem is addressed.

What is LockettePro?
Remember the sign-based lock plugin Lockette that is popular for years? LockettePro is a deep remade & rewrite of the original Lockette. It has massive performance enhancement, fixed bugs and completely customizable.

Why LockettePro?
I love Lockette, but as time goes by, I get deeply depressed with it. Its codebase is messy, performance is bad, unnecessary checks are everywhere... It also uses legacy deprecated methods, having a piston-related bug for years... It is not very possible to fix all the issues, so I started to start a brand new plugin. And today, I am proudly to present you the ultimate sign lock plugin, LockettePro.

LockettePro - Pros
No database. All information required for a lock is recorded on the sign.
Switch to LockettePro and switch back to Lockette worry-free anytime.
Absolutely better performance. Performance test comparison below.
Language files are editable, with UTF-8 support.
Able to disable "bloat" features easily with no affect to performance.
Customizable. For instance, you can set lockable for every single block.
Just saying original Lockette's UUID support is not working between server restarts...

LockettePro - Cons
Lack of admin snooping alert and I am not likely to add this soon.
(Well seems like I have resolved every other cons, great!)

Performance

This test is focused on the most serious performance issue caused by hoppers InventoryMoveItemEvent. The event happens when hoppers are trying to pull items from the container above. Test is performed on my server with a monstrous Chest-Hopper rig consisting 10000 sets of locked chest and hoppers. A hopper tries to pull an item from a chest ever 8 ticks, resulting ~1250 interactions per tick.

Lockette: 41.8 microseconds per event

LockettePro without cache: 19.4 microseconds per event

LockettePro with cache set to 10 seconds: 4.3 microseconds per event

Dependency
ProtocolLib if you use UUID support. Soft-depended supported plugins could be found as a list below.

How to Use LockettePro?
The usage of Lockette and LockettePro are exactly the same.
For players, just hold a sign in your hand, then right click a chest or any lockable block. If you want to lock a door, you may put a sign on the block above or below the door too. You may also SHIFT+RIGHT CLICK the block to prevent it get automatically locked, or you can write [Private] text manually on signs as well.
