Support for this was introduced in PHP 8.0, though not mentioned in any changelog: php/php-src#5777
This simplifies the subprocess handling considerably. However, there is a potential for problems if PHP generates any E_* errors, since these get written to STDOUT as well.
To avoid error messages being treated as a command, a hash is attached to each IPC message, seeded with an incrementing counter. This prevents error messages causing command replays or unintended commands.
Unfortunately, PHP doesn't support binding pipes other than stdin/stdout/stderr on Windows for the child process, so we have to use stdout for this. In the future, if it becomes possible, a dedicated pipe for the purpose should be introduced. We'd need something like php://fd/<number> to work on Windows.
Use reflection to locate BlockTypeIds and ItemTypeIds for VanillaBlocks/VanillaItems
Since BlockTypeIds and ItemTypeIds are derived from VanillaBlocks and VanillaItems respectively anyway (they only exist to allow identifying blocks/items without having to create instances of them), this hack is probably OK, and reduces the chances of mistakes.
Previously it was explored to have these IDs generated by auto-incrementing in VanillaBlocks/Items and have the constants generated that way, but this proved to be too problematic because of unstable diffs no matter how we chose to sort the elements. See #6313 for previous research on the subject.
This is obviously not a desirable hack to keep long-term. In the future it will probably make sense to redesign VanillaBlocks like so:
enum VanillaBlocks { ... }
VanillaBlocks::STONE (the type ID)
VanillaBlocks::STONE->new() (to create a block)
However, more research is needed on this, as I'd prefer not to make block creation any more verbose.
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.
