Duplicate UUID Resolve Option Due to a bug in https://github.com/PaperMC/Paper/commit/2e29af3df05ec0a383f48be549d1c03200756d24 which was added all the way back in March of 2016, it was unknown (potentially not at the time) that an entity might actually change the seed of the random object. At some point, EntitySquid did start setting the seed. Due to this shared random, this caused every entity to use a Random object with a predictable seed. This has caused entities to potentially generate with the same UUID.... Over the years, servers have had entities disappear, but no sign of trouble because CraftBukkit removed the log lines indicating that something was wrong. We have fixed the root issue causing duplicate UUID's, however we now have chunk files full of entities that have the same UUID as another entity! When these chunks load, the 2nd entity will not be added to the world correctly. If that chunk loads in a different order in the future, then it will reverse and the missing one is now the one added to the world and not the other. This results in very inconsistent entity behavior. This change allows you to recover any duplicate entity by generating a new UUID for it. This also lets you delete them instead if you don't want to risk having new entities added to the world that you previously did not see. But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options. It is recommended you regenerate the entities, as these were legit entities, and deserve your love.

Subject: [PATCH] Duplicate UUID Resolve Option
Due to a bug in https://github.com/PaperMC/Paper/commit/2e29af3df05ec0a383f48be549d1c03200756d24
which was added all the way back in March of 2016, it was unknown (potentially not at the time)
that an entity might actually change the seed of the random object.
At some point, EntitySquid did start setting the seed. Due to this shared random, this caused
every entity to use a Random object with a predictable seed.
This has caused entities to potentially generate with the same UUID....
Over the years, servers have had entities disappear, but no sign of trouble
because CraftBukkit removed the log lines indicating that something was wrong.
We have fixed the root issue causing duplicate UUID's, however we now have chunk
files full of entities that have the same UUID as another entity!
When these chunks load, the 2nd entity will not be added to the world correctly.
If that chunk loads in a different order in the future, then it will reverse and the
missing one is now the one added to the world and not the other. This results in very
inconsistent entity behavior.
This change allows you to recover any duplicate entity by generating a new UUID for it.
This also lets you delete them instead if you don't want to risk having new entities added to
the world that you previously did not see.
But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options.

Improvements to Logging Warnings/Dupe Entities - Resolves #1544 1) Removed "Regen" mode of Dupe UUID resolver, forced safe. Some servers who updated before we had safe mode added still had this value. There's really no reason to keep this mode, as we've seen that vanilla triggers this often and 99.9999999% of cases will be an actual duplicate that needs to be deleted. 2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages only show up if the debug.entities flag is on. This will stop server owners from panicing from seeing these logs, and stop opening bug reports on this, only for us to tell you "don't worry about it". 3) Avoid adding entities to world that are already added to world. This can be triggered by anything that causes an entity to be added to the world during the chunk load process, such as chunk conversions. Issue #1544 was a case of this. 4) Removed debug warning about ExpiringMap. Nothing more I know to do about this anyways. We recover from it, stop warning to reduce noise of issues to us.

Add "Safe Regen" Duplicate UUID resolver and make default After witnessing behavior of the regeneration logs, its clear that Vanilla has had bugs with saving duplicate entities for a while.... Some entities are saved in multiple chunks, and now we are bringing those duplicates out that use to never surface. This mode will analyze if the entity appears to be a duplicate (near the other dupe uuid) and delete the entity instead. This should reduce regenerations to entities that are nowhere near each other, and therefore more likely to be subject to real UUID collisions due to our previous bug, and therefor should survive the chunk load.

Fix Dupe UUID logic triggering when the duplicate is pending unload Vanilla logic checks unload queue and overwrites if its in it. we're triggering this if a chunk unloads, and reloads immediately in same tick.

Improvements to Logging Warnings/Dupe Entities - Resolves #1544 1) Removed "Regen" mode of Dupe UUID resolver, forced safe. Some servers who updated before we had safe mode added still had this value. There's really no reason to keep this mode, as we've seen that vanilla triggers this often and 99.9999999% of cases will be an actual duplicate that needs to be deleted. 2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages only show up if the debug.entities flag is on. This will stop server owners from panicing from seeing these logs, and stop opening bug reports on this, only for us to tell you "don't worry about it". 3) Avoid adding entities to world that are already added to world. This can be triggered by anything that causes an entity to be added to the world during the chunk load process, such as chunk conversions. Issue #1544 was a case of this. 4) Removed debug warning about ExpiringMap. Nothing more I know to do about this anyways. We recover from it, stop warning to reduce noise of issues to us.

Add "Safe Regen" Duplicate UUID resolver and make default After witnessing behavior of the regeneration logs, its clear that Vanilla has had bugs with saving duplicate entities for a while.... Some entities are saved in multiple chunks, and now we are bringing those duplicates out that use to never surface. This mode will analyze if the entity appears to be a duplicate (near the other dupe uuid) and delete the entity instead. This should reduce regenerations to entities that are nowhere near each other, and therefore more likely to be subject to real UUID collisions due to our previous bug, and therefor should survive the chunk load.

Add "Safe Regen" Duplicate UUID resolver and make default After witnessing behavior of the regeneration logs, its clear that Vanilla has had bugs with saving duplicate entities for a while.... Some entities are saved in multiple chunks, and now we are bringing those duplicates out that use to never surface. This mode will analyze if the entity appears to be a duplicate (near the other dupe uuid) and delete the entity instead. This should reduce regenerations to entities that are nowhere near each other, and therefore more likely to be subject to real UUID collisions due to our previous bug, and therefor should survive the chunk load.

Improvements to Logging Warnings/Dupe Entities - Resolves #1544 1) Removed "Regen" mode of Dupe UUID resolver, forced safe. Some servers who updated before we had safe mode added still had this value. There's really no reason to keep this mode, as we've seen that vanilla triggers this often and 99.9999999% of cases will be an actual duplicate that needs to be deleted. 2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages only show up if the debug.entities flag is on. This will stop server owners from panicing from seeing these logs, and stop opening bug reports on this, only for us to tell you "don't worry about it". 3) Avoid adding entities to world that are already added to world. This can be triggered by anything that causes an entity to be added to the world during the chunk load process, such as chunk conversions. Issue #1544 was a case of this. 4) Removed debug warning about ExpiringMap. Nothing more I know to do about this anyways. We recover from it, stop warning to reduce noise of issues to us.

Duplicate UUID Resolve Option Due to a bug in https://github.com/PaperMC/Paper/commit/2e29af3df05ec0a383f48be549d1c03200756d24 which was added all the way back in March of 2016, it was unknown (potentially not at the time) that an entity might actually change the seed of the random object. At some point, EntitySquid did start setting the seed. Due to this shared random, this caused every entity to use a Random object with a predictable seed. This has caused entities to potentially generate with the same UUID.... Over the years, servers have had entities disappear, but no sign of trouble because CraftBukkit removed the log lines indicating that something was wrong. We have fixed the root issue causing duplicate UUID's, however we now have chunk files full of entities that have the same UUID as another entity! When these chunks load, the 2nd entity will not be added to the world correctly. If that chunk loads in a different order in the future, then it will reverse and the missing one is now the one added to the world and not the other. This results in very inconsistent entity behavior. This change allows you to recover any duplicate entity by generating a new UUID for it. This also lets you delete them instead if you don't want to risk having new entities added to the world that you previously did not see. But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options. It is recommended you regenerate the entities, as these were legit entities, and deserve your love.

Duplicate UUID Resolve Option Due to a bug in https://github.com/PaperMC/Paper/commit/2e29af3df05ec0a383f48be549d1c03200756d24 which was added all the way back in March of 2016, it was unknown (potentially not at the time) that an entity might actually change the seed of the random object. At some point, EntitySquid did start setting the seed. Due to this shared random, this caused every entity to use a Random object with a predictable seed. This has caused entities to potentially generate with the same UUID.... Over the years, servers have had entities disappear, but no sign of trouble because CraftBukkit removed the log lines indicating that something was wrong. We have fixed the root issue causing duplicate UUID's, however we now have chunk files full of entities that have the same UUID as another entity! When these chunks load, the 2nd entity will not be added to the world correctly. If that chunk loads in a different order in the future, then it will reverse and the missing one is now the one added to the world and not the other. This results in very inconsistent entity behavior. This change allows you to recover any duplicate entity by generating a new UUID for it. This also lets you delete them instead if you don't want to risk having new entities added to the world that you previously did not see. But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options. It is recommended you regenerate the entities, as these were legit entities, and deserve your love.

Improvements to Logging Warnings/Dupe Entities - Resolves #1544 1) Removed "Regen" mode of Dupe UUID resolver, forced safe. Some servers who updated before we had safe mode added still had this value. There's really no reason to keep this mode, as we've seen that vanilla triggers this often and 99.9999999% of cases will be an actual duplicate that needs to be deleted. 2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages only show up if the debug.entities flag is on. This will stop server owners from panicing from seeing these logs, and stop opening bug reports on this, only for us to tell you "don't worry about it". 3) Avoid adding entities to world that are already added to world. This can be triggered by anything that causes an entity to be added to the world during the chunk load process, such as chunk conversions. Issue #1544 was a case of this. 4) Removed debug warning about ExpiringMap. Nothing more I know to do about this anyways. We recover from it, stop warning to reduce noise of issues to us.
