Added the following new blocks:
- All types of Copper Bulb
- All types of Copper Door
- All types of Copper Trapdoor
- All types of Chiseled Copper
- All types of Copper Grate
we don't actually care about the specific values, only whether all the blocks and their states have been correctly registered.
I'd prefer to track all of the state data permutations, but the APIs for that are private, so tracking the number of permutations will have to suffice (this should be good enough to detect bugs anyway, and also takes way less space).
while this would be more user-friendly as a config option, configs are a pain because they aren't initialized until after the server log has already been set up.
In any case, I foresee that people will likely want to bake this into Dockerfiles directly anyway.
`server.log` is not rotated by default and grows unmanageably large, to the point where it's so huge that it's not possible to read it with any standard text editor anymore.
This PR implements automatic log rotation.
- When the `server.log` reaches 32MB in size, it's moved to the `log_archive/` folder of the server's data folder.
- The archive's file name will look something like this: `server.2024-03-15T15.26.24.0.log`
- The file's name contains the date and time when the file was archived. This may be useful if you're trying to find logs from a particular time frame.
This has several benefits:
- Much more easily find logs from a particular time frame without scrolling through GBs of logs
- Free up space without stopping the server - Archived log files in `log_archive/` can be safely deleted and/or modified while the server is running
If you want to automatically compress or clean up the log files, I suggest an external cron job or disk watcher.
Closes#4029.
PHPStan will verify that these matches cover all cases, which guarantees that all cases will be covered.
In addition, if PHPStan is not used, the constructors will immediately bail out when they hit a case that isn't covered.
The only downside is the extra indentation :(
we can safely assume this for blocks (though the type info doesn't reflect it) but this is not safe to assume for random APIs that might be used by plugins.
Farmland can end up scanning up to 162 blocks looking for water in the worst case. This is obviously not great for huge farms where there are thousands of blocks of the stuff.
In most farms, the water won't be moved, and nor will the farmland. This means that we can avoid this costly search on random updates.
This PR implements a cache using blockstate data (only possible in PM5) which stores an index mapping to a coordinate offset where water was previously found by this farmland block. This allows the farmland to avoid water searching entirely in most cases.
This is a colossal improvement as compared to scanning the whole 9x2x9 area every time, which, on average, scans about 40 blocks to find water if the water is at the same Y coordinate. In real terms this translates into about a 8x performance improvement for farmland (see timings below).
xxhash is generally well known for its hash key properties, so this is a suitable use case.
We XOR the state data with a partial hash of xxh3(typeID), which provides sufficient hash distribution regardless of the size of state data.
The previous method started to break down as the number of bits exceeded the number of significant bits of type ID (about 10 currently).
As well as being better for hash distribution regardless of state data size, this also reduces the load factor of RuntimeBlockRegistry to 1.08 (previously around 1.24), which is a nice bonus.
