This required the following:
- A generation task (taskA) to already be running for any chunk (chunkA)
- A chunk (chunkB) is requested for generation, and the task (taskB) to do the generation
is commenced immediately
- chunkB generation promise is aborted (e.g. due to chunk unload) and
taskB is orphaned
- chunkB is subsequently re-requested, but ends up in the generation
queue because taskB is still running
- taskA completes and drains the generation queue
- chunkB attempts to be populated a second time, but taskB has not yet
been collected, resulting in an assertion failure.
This bug has been appearing intermittently ever since PM 4.0 release.
For most users there is no obvious effect since production servers don't
have assertions enabled; however, it's unclear what kind of weird side
effects this bug may have had.
The following API constants have been added:
- tile\BrewingStand::BREW_TIME_TICKS
The following public API methods have been added:
- utils\BrewingStandSlot->getSlotNumber() : int
- CraftingManager->getPotionTypeRecipes() : array<string, array<string, PotionTypeRecipe>>
- CraftingManager->getPotionContainerChangeRecipes() : array<int, array<string, PotionContainerChangeRecipe>>
- CraftingManager->registerPotionTypeRecipe(PotionTypeRecipe $recipe) : void
- CraftingManager->registerPotionContainerChangeRecipe(PotionContainerChangeRecipe $recipe) : void
The following classes have been added:
- BrewingRecipe
- PotionTypeRecipe
- PotionContainerChangeRecipe
- BrewItemEvent
- BrewingFuelUseEvent
- PotionFinishBrewingSound
this was caused by 083a1e1ff6b6ff5c0c1ba14250d2b026af103b90.
This was discovered by a new PHPStan rule I'm working on, which disallows overwriting the values of parameter variables. During the refactor of this function to correct the error, another error appeared: Variable might not be defined.
This is yet another excellent example of why mutability is bad.
I've stuck to only doing this in the places where I'm sure we should never get false back. Other places I'm less sure of (and I found more bugs along the way).
we don't usually add VanillaItems entries for blocks since they already exist in VanillaBlocks, but air has a special use case specifically as an itemstack, so we make an exception for this case.
this fixes many cases of corruption during disk-full situations - file_put_contents() would write an empty file, destroying the original data.

this fixes a wide range of blocks with invalid blockstates becoming update! blocks on the client.
The most common occurrence of this was air with nonzero metadata left behind by world editors which set blockIDs but not block metadata. This caused large ghost structures of update! blocks to appear from nowhere.
The performance impact of this is very minimal (20 microseconds per chunk load in timings, compared to average 660 microseconds to load tiles).
