this is intended to replace PluginCommand and CommandExecutor, both of which are overengineered and unfit for purpose.
Allowing a closure allows much greater flexibility.
We can't use this within the core yet, as plugins will expect PluginBase->getCommand() to return PluginCommand (with its associated setExecutor() and similar APIs).
However, I think this is useful enough to add by itself.
The following callbacks can now be registered in timings, to allow threads to be notified of these events:
- Turning on/off (`TimingsHandler::getToggleCallbacks()->add(...)`)
- Reset (`TimingsHandler::getReloadCallbacks()->add(...)`)
- Collect (`TimingsHandler::getCollectCallbacks()->add(...)`)
Collect callbacks must return `list<Promise>`. The promises must be `resolve()`d with `list<string>` of printed timings records, as returned by `TimingsHandler::printCurrentThreadRecords()`. It's recommended to use 1 promise per thread.
A timings report will be produced once all promises have been resolved.
This system is used internally to collect timings for async tasks (closes#6166).
For timings viewer developers:
Timings format version has been bumped to 3 to accommodate this change. Timings groups should now include a `ThreadId` at the end of timings group names to ensure that their record IDs are segregated correctly, as they could otherwise conflict between threads. The main thread is not required to specify a thread ID. See pmmp/timings@13cefa6279 for implementation examples.
New PHPStan error is caused by phpstan/phpstan#10924
This binds internal sneaking to whether or not the player is currently pressing the shift key, which fixes#5792 and fixes#5903.
However, it does introduce visual issues with sneaking, as explained in #6548. This needs to be worked on separately. For now, it's better we trade 2 functional bugs for 1 visual bug.
this is no longer used by the core, and as far as I can tell no plugin uses it either.
it was used in the past for chat broadcast channels, but not anymore.
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.
