Test case:
- plugin2 depends on nonexistent plugin1
- plugin3 depends on plugin2
At random occasions, plugin3 would be loaded before plugin2, because plugin2 load would be deferred in the expectation of plugin1 being loaded. This would result in the assumption that plugin3's softdepend plugins would not be loaded, so they were ignored.
We fix this problem by removing missing plugins from softdepend if they were not present on a scan of the directory. This way, we don't ignore any unresolved deferred dependency resolutions.
some things which were copy pasting PM classes into plugins were causing incorrect detection here. The path cleaning guarantees that all plugin paths will start with "plugins/", so we can use that to check instead.
loadbefore operates by injecting self into the target plugin's soft-dependencies. The problem is that these soft-dependency lists are overwritten if the target plugin's soft-dependencies are resolved after the loadbefore of the origin plugin.
the timeout was entirely useless, because:
- when shorter than 25.6 seconds (512 ticks) it would cause caches to be needlessly destroyed and regenerated
- when longer than 25.6 seconds, just made outdated caches persist for longer, even after the query info was regenerated.
This now uses a mark-dirty model to deal with caches, which means that plugin modifications to the query data will be reflected immediately, regardless of when they are made. Previously, modifying the result of Server->getQueryInformation() would have inconsistent results.
On most filesystems, plugins are loaded in lexical order because that's how the filesystem gives the files to us. This is a problem because it can hide bugs with dependency resolution on specific platforms with this behaviour, while inexplicably breaking on other platforms where the load order is different or undefined.
This change prevents plugins depending on any file yield order by randomizing the order in which plugin files are checked for loadability.
this causes some breakage to the behaviour of Terminal, and for that reason this is going on 4.0.
Terminal::hasFormattingCodes() will no longer auto-detect whether colour codes are supported.
we can't get rid of these hacks entirely because BAcKWARdS ComPaTIbilitY, but this at least ensures that things over PID 127 won't burn the house down when 1.12 gets here. This also reduces conflicts with 4.0 line.
valid crashdumps are usually self explanatory and include all required information like OS/version/etc, so there's no need to force reporters to rewrite a bunch of extra information that should already be in the crashdump.
this was making the location table point to an offset that did not yet exist, which caused the region header consistency check to discard the region as corrupted the next time it was loaded.
this works around a bug where corrupted text on preexisting signs can mess up the client. This also prevents corrupted text getting onto signs in the future by having them scrubbed and validated before applying them.
this fixes effect durations being off (mostly), closes#2650
there are still some minor differences, but this is closer matching than the previous version.
this is a partial fix for #2717, but still not ideal because it'll spam whenever a chunk is attempted to be generated. However, fixing this properly requires potentially breaking API changes.
this now has a mouthful of a name. I'd like to invert it, but I can't do that without silently breaking backwards compatibility, which is unacceptable.
not ready to call this "fixed" yet because any chests that were already affected by the bug will still be affected. This change will prevent the creation of more broken chests like this.
Plugins would indirectly trigger permissible recalculation too early in the login sequence, which then caused their permissions to be recalculated and subscribing them to the broadcast permission far too early.
generating 1 large bounded random costs the same as generating 4 small ones, so it makes more sense to do it like this instead.
Note that prior to 7.1 this code would not work due to it not handling 64-bit appropriately.
In vanilla it doesn't drop the exact number of points you collected. Rather, you lose a little for every level above 1 you had (1 level requires 7 points, later levels require +2 per level), and can recover at most 100 points. Hence, if you had 10 levels, you get back enough points to fill 5 levels and most of a 6th. 14-15 levels gets you the upper bound of about 7.5 levels.
This is not identical to vanilla, but I don't care because it gets rid of edge cases and also makes it easier to integrate with EntityDeathEvent in the future.
I believe this is caused by a bug in the linux kernel, since it only impacts certain machines I tested (one, to be specific). Whatever the case, setting a max backlog size is prudent anyway, and fixes the problem.
Packets with a too-short payload would either cause the RCON thread to hang until the client disconnected, or crash the RCON thread entirely.

fix some bugs in RCON
This will now throw an exception at the source instead of crashing when the entity is saved, which should put the blame on the correct plugin responsible for this.
This also includes magic method hacks to preserve backwards compatibility, since the fireTicks field is now protected.
Encoded tags larger than 32KB overflow the length field, so we can't send these over network. However, it's unreasonable to randomly throw this burden off onto users by crashing their servers, so the next best solution is to just not send the NBT. This is also not an ideal solution (books and the like with too-large tags won't work on the client side) but it's better than crashing the server or client due to a protocol bug. Mojang have confirmed this will be resolved by a future MCPE release, so we'll just work around this problem until then.
If a plugin was involved in a crash, we can't safely blame it for the crash, since it might have innocently triggered a core bug. Furthermore, it's difficult to accurately detect plugin causing things like invalid argument crashes.
it's much less expensive to just calculate the modulo of the current tick and 20, and overwrite past entries. The effect is the same. The only difference is that the arrays won't be ordered by time, but that doesn't matter anyway.
This is better for performance because these then don't need to be reevaluated every time they are called.
When encountering an unqualified function or constant reference, PHP will first try to locate a symbol in the current namespace by that name, and then fall back to the global namespace.
This short-circuits the check, which has substantial performance effects in some cases - in particular, ord(), chr() and strlen() show ~1500x faster calls when they are fully qualified.
However, this doesn't mean that PM is getting a massive amount faster. In real world terms, this translates to about 10-15% performance improvement.
But before anyone gets excited, you should know that the CodeOptimizer in the PreProcessor repo has been applying fully-qualified symbol optimizations to Jenkins builds for years, which is one of the reasons why Jenkins builds have better performance than home-built or source installations.
We're choosing to do this for the sake of future SafePHP integration and also to be able to get rid of the buggy CodeOptimizer, so that phar and source are more consistent.
Since 3.2 there have been some runtime performance issues related to garbage collection and dynamic AsyncWorker booting. This is partly because of GC being dumb about shutting down what it thinks are "unused" workers. A worker which has been idle for a single tick is considered the same as a worker which has been idle for hours. The result of this is that on active servers, workers would get shut down and then immediately restarted because of something like chunk sending. Since booting an async worker is frightfully expensive, this causes lag spikes, which is obviously bad.
This commit changes the GC mechanism to only shutdown workers which have not been used for the last 5 minutes.
This was removed way back in 2016 because of an unidentified bug which caused permissible commands not to show up on the client. Back then, command parsing and validity checks were client-sided, and the client would simply not send the command at all if it didn't recognize it. Now, that problem is gone, so it doesn't matter as much if there are permission bugs which cause commands to be erroneously missing.
closes#2625
this bug has existed for so long I forgot it was still here. People stopped pestering me to do something about it, and as a result I forgot to do anything about it.
This hack isn't perfect, but it filters out the worst of the noise. It has side effects for legitimate fast double-clicks, but I don't think anyone will be too bothered - just click more slowly.
This hack may also have negative side effects on poor connections where latency spikes are a problem, but there isn't really much that can be done about that.
Always order chunks ASAP on chunk change, not just during the spawn sequence. This fixes the sluggishness observed in BlockSniper when doing async chunk modifications.
I don't know why this would be missing, but in some cases it is, as seen in the crash archive. Whatever the case, we shouldn't be shitting the bed because of this.
this was observable by planting a sapling underneath an existing tree and punching it with bone meal.
This change will also prevent trees generating too close together.
this should have been done a long time ago, but we didn't want to cause compatibility problems with CA. Now it enforces version checks, this isn't a problem anymore.
this doesn't fix shit but it at least doesn't crash. Fixing this properly can't be effectively done any other way without backwards compatibility breaks. Fortunately it's not common practice to grow trees at the top of the world.
this attribute is not visible on the client and is only used for controlling saturation depletion. It's extremely spammy and as such really shouldn't be sent over network. This has also been causing some minor client-side performance issues in survival.
this must have been missing for how many years now? thanks @shoghicp
this is why we don't do releases on friday night... in my defence my device had the beta installed...
This allows to save the language without rewriting pocketmine.yml. Since this is a "standard" config option (something that the user might want to directly modify) it's reasonable to put it in server.properties. pocketmine.yml is generally reserved for more advanced configuration options.
this technically involves non-breaking API changes which should happen on a patch release, but I can't be bothered with the dust cleanup, so we'll just blow it away now. It doesn't hurt anyone anyway.
This was the cause of a bug with regeneration which caused players taking fatal damage under regeneration not to die correctly. On the server side they would die and immediately regenerate some health, which would cause the next attribute sync to not report the health drop to zero, which made the client unaware that it was dead.
Perhaps attributes should be forcibly synced in some circumstances, but nonetheless regeneration shouldn't apply post-death.
This is an incremental improvement over 4a6841a5a4. This change works better because it also reduces disk spam of crashdumps.
This will now sleep if the server uptime was less than 120 seconds before crashing. If unattended, this will clamp down on automated crashdump spam. If attended, the user can simply press CTRL+C to abort the process and skip the delay.
This takes advantage of two key behaviours of PHP:
1. Assigning a string does not copy the string
2. Changing an offset in a string causes the string to be copied.
These two factors combined, along with the fact that blocklight and skylight arrays are usually all-zeros, allow us to produce a significant memory usage reduction of loaded chunks.
A freshly generated PM world with 3,332 chunks loaded drops from 310MB to 200MB memory usage with these changes applied.
This was suggested recently by @TheDeibo. We don't want users running source-code installations unless they are developers, and developers should know how to boot a source-code installation anyway.
this process of fast-serialization, fast-deserialize, network-serialize is an order of magnitude slower than just doing the network encode directly on the main thread, and also copies more useless data.
For the main thread, the figures were something like 3x more expensive, and then an extra 7x for deserialization on the worker thread. This is a ridiculously large overhead.
this is perfectly fine to use, and preferable to getting a cyclic ref to the scheduler. TaskScheduler->cancelTask() does pretty much the exact same thing, and the scheduler internals are designed to deal with this anyway.
this should produce some reduction in spam at the source.
This could also be used to control the rate at which constantly-crashing servers restart to stop them spamming the disk as well, but the main concern here is eliminating crash archive involuntary DDoS by crashy servers.
This supersedes addChunkPacket() in most cases, and has a more clear name. It broadcasts the given packet to every player who has the target position within their chunk load radius.
This can happen when a light source is removed and later encountering another light source to fill the gap. A higher light level may get set and then not propagated. This bug is difficult to explain, but fairly easy to reproduce.
Grass can cause issues here by requesting blocks randomly offset away from itself, which can cause silent chunk loading on chunk ticking. It also causes crashes if chunk autoloading is taken away, which is obviously undesired.
It was also noticed that player chunkloaders cause chunks to start getting ticked as soon as they load their first chunk, which is before the entity is visible to everyone else on the server. This is probably undesired behaviour.
this can happen when eval() is used, and then we get a big blank mess with nothing on it. eval() is a special case that should be handled separately, but for now this is just fixing a bug.
This was observed in a recent crashdump where a plugin triggered a recursion error, but the stack trace did not contain any sign of a recursive event call. I conclude that this must have been caused by previous event handlers triggering errors 50 times in order to make the recursion detection break, because the recursion detection did not decrement the counter in cases where an exception was thrown.
while we can't deal with this information, it's needed for the sake of unit testing so we don't shit on every bit of incoming data of these packet types.
Use of this by plugins will produce a lot of undefined behaviour, such as event handlers not being unregistered, scheduled tasks not being removed, and registered permissions causing memory leaks.
This check is completely unnecessary since handlers get unregistered when a plugin is disabled. Additionally, this is an extremely hot path and this change produces a modest 5% performance improvement to event calls.
this is cleaner than leaving the player hanging for 5 seconds (which they'll often timeout from anyway). Banning the IP without kicking the player can often look like "lag" and end up getting brushed off as a performance issue.
this dates back to the days where PM used to kill threads to stop them. Today we're more civilized and ask it to stop nicely, so this isn't necessary anymore.
This has the triple bonus effect of a) making a lot of code easier to read, b) reducing Server::getInstance() usages, and c) removing a whole bunch of Server dependencies.
The network and block namespaces are untouched by this commit due to potential for merge conflicts. These should be dealt with separately on master.
This is dependent on the changes made in b1e0f82cbf. This now makes it possible to call events without fetching a Server reference, allowing to eliminate a vast array of Server dependencies.
The basic principle here is "if you're not expecting it, don't catch it".
Event handlers are **never** supposed to throw exceptions. If they do throw exceptions, it's usually going to one of two things;
1. Broken code producing an error
2. Code triggering (and not catching) a runtime error
Both 1) and 2) boil down to defective code on the part of the event handler, and thus should not be caught by the caller, but instead allowed to crash the server and produce a crashdump.
It's also undesirable to catch unexpected errors here for a few other reasons
- It leaves the owner of the event handler in an unknown, potentially unstable state
- It allows broken code to cause event handlers to spam the logger in events that happen frequently (for example movement handlers)
- It allows the process to continue down a train of further undefined behaviour, which may lead to more errors or ultimately a crash, so it makes no sense to hold off the inevitable.
This has a few advantages that are not merely inverted disadvantages:
- Crash dumps will now be created and automatically submitted for defective event handlers, allowing quicker issue location, debugging and fixing in plugins without manual user interaction
- Event calling now isn't dependent on Server to work.
This assumes that the region is properly garbage-collected and packed, but if the file contains uncollected garbage this may not be the case, resulting in a region larger than a gigabyte.
readline on Windows causes issues with console output corruption. Additionally, PM readline impl is extremely buggy and probably ought to be removed. However, have a hotfix for now.
This came to light after observing cfb6856634 in a fresh light. I noticed that this fix should not have been necessary because clearPermissions() should have dealt with it. Unfortunately, permissions can be set without being set in PermissibleBase->permissions, so this misses things.
This is needed for batched lighting updates to work. It also reduces the overhead involved with simply preparing a lighting update and moves the pain to the execute() instead.
this usually causes the console to get spammed with errors. Additionally, in the case where doTick() throws any exception, it's usually because we're in a state we didn't want to be in, so we really should not carry on trying to keep ticking when something breaks here. Instead, this should generate a crashdump.
Previously every thread using the logger had to inherit runtime-defined INI entries in order for the timezone to be set correctly. This removes that requirement.
- Don't allow the same window ID to be used when another window is already using it
- Detect window ID collisions when selecting IDs for regular containers (should never happen, but anything is possible)
this is an absurd bug that nobody would ever otherwise notice, but the problem is that the doOnFireTick() call isn't evaluated if hasUpdate is already true.
leaving out turtle helmet for now because of complications relating to the effect application - I REALLY don't want to tick armour if I can avoid it, due to the performance concerns.
A common pitfall developers fall into with this function is that it has to be called from the scope of the tile class you're creating NBT for, but people commonly do Tile::createNBT() directly, which then results in cryptic "Tile is not registered" errors. This now throws a BadMethodCallException instead to be fully clear about this.
In the future this will be removed completely once NBT is no longer required to create a tile, but for now this is a confusing issue that should be dealt with.
PhpStorm can't see constructor usages when the class name is dynamic. This causes maintenance problems because cross-referencing constructors called like this doesn't show up dynamic calls.
I am eating my own words this once, because having the tester plugin as a separate repository makes no sense - it is just added barriers to writing proper tests with no actual benefit. Since the tester plugin is specifically intended for CI, it doesn't make sense for it to be in its own module.
The original regex almost completely failed at its objective, because it a) only worked if there was no value for the key, and b) did not prevent all such occurrences getting transformed, while quoting patterns that would not get transformed anyway.
There's no implementation here yet, but that can come later. This lays the ground for allowing plugins to have an integrated method to send forms, as well as a solution to the ID conflict problem.
A built in implementation should not be a concretion and it should be able to be swapped for third party implementations. This enables the possiblity to do so.
Previously any random error could occur during an AsyncTask preparing a chunk, and the Level would never know about it and thus never send the chunk.
I don't know how many invisible-chunk bug cases this fixes, but I expect it's quite a lot.
RuntimeException is very generic and might be thrown for other reasons apart from web request failures.
This is backwards compatible because InternetException is a descendent of RuntimeException. Additionally, getURL() and postURL() have intentionally been left untouched for backwards compatibility's sake.
* Added a new PermissionManager, remove ridiculous cyclic dependencies of Permissions on Server
Aside from all the other ridiculous design problems with the permission system, the biggest problems are its API. This is, once again, a result of poor API design copied from Bukkit.
This pull request removes all permission-related functionality from `PluginManager` and moves it to the `pocketmine\permission\PermissionManager` class.
As can be observed from the removed code in the diff, the permissions system was previously entirely dependent on the Server, because it needed to get the PluginManager for registering permissions. This is utterly ridiculous. This refactor isolates _most_ permission-related functionality within the `permission` namespace.
As mentioned above, this stupid API is a direct result of copying from Bukkit. If you look at the API documentation for Bukkit for `PluginManager` you will see that the methods I'm deprecating here are also in there.
## Changes
- Added a new `PermissionManager` class. This can be accessed via its singleton `getInstance()` static method.
- Deprecated the following `PluginManager` methods - these will be removed no later than 4.0.0:
- `getPermission()`
- `addPermission()`
- `removePermission()`
- `getDefaultPermissions()`
- `recalculatePermissionDefaults()`
- `subscribeToPermission()`
- `unsubscribeFromPermission()`
- `getPermissionSubscriptions()`
- `subscribeToDefaultPerms()`
- `unsubscribeFromDefaultPerms()`
- `getDefaultPermSubscriptions()`
- `getPermissions()`
- Added `Internet::getIP()`, `Internet::getURL()`, `Internet::postURL()`, and `Internet::simpleCurl()`.
- Deprecated the corresponding functions in `Utils`. Updating to the new functions is as simple as replacing `Utils` with `Internet`, since this doesn't break backwards compatibility.
The deprecations should be catered for by plugin developers. These deprecated redirects will be removed no later than 4.0.0.
This reverts commit 0081e30a89.
The logic introduced by this commit is correct in MC JAVA 1.9+. Unfortunately, nobody likes 1.9+ for combat.
Some testing in MCPE vanilla made it apparent that this logic isn't correct for MCPE. The old logic is correct for pre-1.9 knockback.
it's possible to walk off a tower while flying without moving vertically, and this code previously wouldn't detect that, leaving a gaping hole in the anti-cheat.
Under normal circumstances, none of the boxed code will throw exceptions. Under exceptional circumstances, the caller should know about it. Usually the caller is the server. We don't want to catch unexpected exceptions because those should crash the server and generate a crashdump.
this was an interesting bug.
This was discovered by making a projectile's drag 0, making its gravity a factor of its throw force (such that force / gravity = integer value), and then throwing it directly up. At the apex, an error would occur due to trying to do a ray trace with a zero vector.
This also led me to realize that there's an edge case in the current movement system - if an entity's motion reaches 0, it will stop getting movement updates. This can be undesirable when things such as gravity cause motion to become zero when throwing a projectile directly upwards. This will need to be fixed separately.
As discussed in #2297:
Honestly I don't see a fit purpose for async saving at all. It should either always be synchronous or always asynchronous, and at the user's own option. However, this isn't currently possible because Config doesn't enable you to get the serialized content without writing it to disk.
Consider the following code:
```php
for($i = 0, $size = $this->getServer()->getAsyncPool()->getSize(); $i < $size; ++$i){
$this->getServer()->getAsyncPool()->submitTask(new class extends AsyncTask{
public function onRun(){
sleep(5);
}
});
}
$config = $this->getConfig();
$config->set("steve", "hi");
$config->save(true);
$config->set("steve", "bye");
$config->save(false);
```
Output:
```yml
---
steve: hi
...
```
Expected output:
```yml
---
steve: bye
...
```
Additionally, if your configs are causing you performance issues when you're saving, it's a clear sign that
a) you're saving too much
b) you're abusing configs and should consider using a database.
Configs should be used for _simple_ data which does not change much. Configuration is such that the _user_ is expected to be able to modify it. As such, it should never be an issue to save synchronously.
In the future, something like ReactPHP may be introduced to allow proper async saving. When this happens, async saving would always be sequential but non blocking. Using threads for this makes no sense.
I wasn't sure whether this would be considered a bug fix or a feature. Nonetheless, it's a behavioural change, so it belongs in 3.1 if anywhere.
Prior to this, plugins would be required to call saveDefaultConfig() before calling getConfig() or anything else. Calling getConfig() without saveDefaultConfig() first would generate an empty configuration file. Instead, it now saves the default config before loading it.
I don't care if this matches PC behaviour or not. bugs.mojang.com is full of bug reports about this. Just search for "minecraft spawn protection not working" and you'll see what I mean.
If you want to disable spawn protection, actually disable it. This behaviour is something that most users are not aware of and find astonishing when they discover it.
This behaviour was copied from Minecraft PC, and it's nearly as unexpected there as it is here.
This commit reverses the stupidity done in eb0525e892.
fixes#2295
There is still an issue in that the spawn point will not be offset if the chunk is not generated, but this is better than the spawn point being down at y=0. The other issue is a job for another time.
This is quite an interesting bug. If you have
```php
class A{
public function onMove(PlayerMoveEvent $event){} //shouldn't be a handler because this class isn't a Listener
}
class B extends A implements Listener{}
```
then
```php
registerEvents(new B, $plugin);
```
then `A::onMove()` will be registered as an event handler even though `A` is not an instanceof `Listener`.
This was observed by noting that plugins which do something like `extends PluginBase implements Listener` causes `registerEvents()` to try and register `PluginBase` methods as event handlers, which could lead to astonishing behaviour.

this fixes a potential exploit where clients could append JWTs signed with their own keys to the end of the chain containing fake XUID/UUID/username which would then overwrite the legitimate ones in earlier links.
This stems from the fact that the final link of the vanilla chain contains the client's own pubkey, so the client is able to append its own data to the end of the chain.
I considered making this instead save the default config instead of creating an empty config file, but that would be (albeit minor) a behavioural change which therefore belongs in 3.1.
this goes on 3.1 because it changes the behaviour of chunk cloning, which might possibly break some plugins, and this isn't a bug fix.
This should see no change in behaviour other than a minor performance improvement and slight reduction in memory usage.
If there is an empty list of blocks in the changedBlocks array for a chunk, that means that blocks changed the normal way and then were later set the direct way in the same tick. This means that no action needs to be taken on these chunks.
onGround doesn't necessarily reflect 0 motion, because something else could change the motion prior to the onGround flag getting updated - for example 2 knockbacks in a row.
This can happen when an attacker attacks a victim wearing thorns armour while having low health, which prior to this commit would cause the tool to be duplicated.
this has already been seen to cause duplication bugs when thorns is used. Anything else that modifies inventory during applyPostDamageEffects() when the mob is possibly dead will also cause duplication issues.
This allows controlling how arrows are picked up:
- by anything
- by only creative players
- by nothing
This adds new API methods to Arrow:
- getPickupMode()
- setPickupMode()
This adds new public constants to Arrow:
- PICKUP_NONE
- PICKUP_ANY
- PICKUP_CREATIVE
they got removed from the tasks array, but not from the queue (for performance reasons). The queue gets cleaned up by the heartbeat, but it was checking if there were things in the main array, not in the queue.
There are a couple of other bugs with cancelling tasks that this doesn't fix that are rather more complicated to deal with.
krakjoe's profiler hasn't been updated since 2013. I doubt it's going to get updated in the near future. These days we use xdebug, which is either always on or always off.
PhpStorm can't see these or understand how they are being called, which is very annoying for bug hunting. Additionally, we already have the CodeOptimizer for this.
This has long been a waste of time and creativity, and that's only going to continue to be the case now that we're going to be properly versioning. New codenames every couple of months is not worth the bother.
This may raise a few eyebrows.
Does this mean that all the things that were planned for API 3.0.0 are done?
Not at all. The plans laid out in December 2016 for API 3.0.0 were far too ambitious, and as a result the ALPHA series dragged out forever (18 months now). This is a break away from those plans, to bring development and release flow back to some sort of sanity.
Does this mean that my plugins will stop breaking all the time now?
No, it does not! Development isn't going to stop, although breaking changes will be confined only to major API releases. It's anticipated that the major API version will be bumped as nearly as often as the ALPHA version was during the last 18 months. The reason for this return to 3.0.0 is to allow us to fine-tune our release flow so that plugin developers can get advantage of newer, non-breaking API features without having to bump the API in a breaking way.
What are the criteria for the API versions now?
- Major: This will be bumped for breaking changes, changes which will break plugins. it's expected that we'll roll out new major versions regularly.
- Minor: This will be bumped when non-breaking feature additions are made, such that API 3.0.0 plugins would still load on 3.1.0. However, plugins requiring 3.1.0 will not run on 3.0.0.
- Patch: This will be bumped for bugfix updates. Plugins requiring 3.0.0 will work on 3.0.1, but not vice versa.
TL;DR: This insanity has gone on far too long.
This features a near-total rewrite of PluginLoaders and some code associated with them.
Highlights:
- PluginManager->registerInterface() does not return anything, and now accepts a PluginLoader instance instead of a string.
- PluginLoader itself is drastically simplified. getPluginFilters(), enablePlugin() and disablePlugin() are now removed. loadPlugin() responsibilities are now solely confined to doing whatever is necessary to make the plugin's classes visible by the server, and does not emit log messages or check for data directories.
- PluginBase->init() and PluginBase->isInitialized() have been removed.
- Plugin interface now declares a signature for the constructor which implementations must comply with.
- Plugin interface now declares setEnabled().
This changes how the AsyncPool works so that it does not immediately always start all of the workers in the pool.
Instead, workers will be started only when an idle worker was not found.
This allows for significant memory footprint reductions while idle.
In effect the async-workers setting in pocketmine.yml now dictates a _maximum_ pool size, not a fixed pool size.
* Implemented InventoryEventProcessor, fixes#1986
Event processors can now be registered and unregistered at will. Entity inventory/armor change events are now handled by event processors instead of the inventories themselves, which allows enabling/disabling the calling of these events at will.
This now avoids stupid things happening when initializing inventory contents, since the callers for those events are now registered _after_ the contents are initialized.
the Entity base also accounts for this, and assuming that this is automatically valid is causing lots of crashes. I am not sure of the circumstances under which this is suddenly becoming null, but this shouldn't assume that the level is valid nonetheless.
If the same chunk is set into multiple different places in the world, the chunk's position is no longer able to be relied on, because it will have the position of the last place it was set. This results in chunks not getting sent correctly when the same chunk is set in multiple places.
This avoids the bug by using known valid coordinates (using chunk hashes) to establish the real coordinates, and also adds an assert to notify developers should they unintentionally set a duplicate chunk by mistake.
- Doesn't need to be pre-populated with biomes prior to calculating the heatmap - now population of biomes is entirely dependent on the lookup function, improving consistency
- Uses an abstract class method for lookup instead of callback (use anonymous class instead)
- Faster because the heatmap is directly populated with biomes instead of biome IDs, removing an unnecessary lookup.
- Removed `Server->getScheduler()`. All plugins now have their own scheduler which is accessible using `Plugin->getScheduler()`. Aside from being syntactically more concise and pleasant, this also allows much more effective management of tasks when plugins are disabled.
- Removed `PluginTask` class. Before this PR it was necessary for plugin tasks to descend from `PluginTask` to ensure that the server could clean them up correctly on plugin disable. This is no longer necessary, so the `PluginTask` class has been removed. Plugins may now utilize the `Task` class as a base if they like.
- Added `Server->getAsyncPool()`. Since the global scheduler does not exist any more, it does not manage the server's `AsyncPool` any more. Additionally, `ServerScheduler` was previously bloated by a lot of `AsyncTask` related methods, which are now not necessary because direct access to `AsyncPool` is granted instead.
- `ServerScheduler`:
- `ServerScheduler` has been renamed to `TaskScheduler` since it is now a general-purpose task scheduler which is non-dependent on the user. This allows much greater flexibility and also makes it possible to unit-test.
- All `AsyncTask`/`AsyncPool` related methods have been removed - the task scheduler does not manage the async pool anymore.
- Calls to `Server->getScheduler()->scheduleAsyncTask()` should be replaced with `Server->getAsyncPool()->submitTask()`.
- Calls to `Server->getScheduler()->scheduleAsyncTaskToWorker()` should be replaced with and `Server->getAsyncPool()->submitTaskToWorker()`.
## Backwards compatibility
This poses significant backwards compatibility breaks for any plugins utilizing Tasks or AsyncTasks. These breaks are described above, along with basic upgrade steps. The upgrade process is quite straightforward.
## Follow-up
A large part of the goal with this pull request is to modularize these parts of the code so that they can be reused and also unit-tested. I would like to remove the existing test set from TesterPlugin at some stage when the AsyncPool can operate without a Server.
Because of the above, I am considering making further backwards incompatible changes directly to `AsyncTask` to remove the `Server` parameters from `onCompletion()` and `onProgressUpdate()`. These shouldn't be too difficult to upgrade from and can be prepared for in advance.
This is a significant breaking change for anything utilizing Tiles as they now do not store their NBT at runtime anymore.
This is another step in the process of ridding PocketMine-MP of runtime NBT.
It can be noticed that all tiles are now using class fields to store properties instead of NBT, which is much faster, uses less memory and is also more concise when written in code.
Highlights:
- Tile->namedtag has been removed.
- Tile->saveNBT() now accepts a CompoundTag() parameter. Typically it's expected that this will be fed a newly-created CompoundTag (this part may be improved in the future).
- New internal methods Tile->readSaveData() and Tile->writeSaveData() have been added. Instead of overriding __construct() and saveNBT() to load and save properties from NBT, you should now implement these methods instead.
This is not final and will see further changes before it's done.
This is caused by the Spawnable constructor calling spawnToAll() before the tile is fully initialized. I really really really hate constructors that _DO_ things by themselves.
this never really worked properly and is a bad idea anyway. This was the cause of many sign-going-blank bugs before it was broken (by me), and since it's broken it's now useless. I don't think there's any practical way to make this work properly, so I leave it up to plugins to decide whether or not they want to cancel sign editing in protected areas. PocketMine-MP built-in spawn protection will already block this by default anyway.
By default it starts 30 workers on Travis because there are 32 logical cores available. This is ridiculously excessive and pollutes the log with debug spam.
This change breaks pretty much all API pertaining to synchronous task scheduling.
Significant changes:
- Server->getScheduler() has been removed
- Plugin->getScheduler() has been added - every plugin now has its own scheduler
- Because schedulers are now per-plugin, it is now unnecessary for PluginTask to exist because stopping plugin tasks on plugin disable is as simple as destroying the plugin's scheduler. Therefore PluginTask has now been removed and it is expected for things to now use the base Task class instead.
For the most part, plugins will simply need to change Plugin->getServer()->getScheduler()->... to Plugin->getScheduler()->...
Another highlight is that plugin tasks now no longer have global IDs - they are unique to each scheduler.
This commit contains quite a few breaking changes with respect to how AsyncTasks are handled. This is necessary to allow separation of the ServerScheduler and the AsyncPool, because in the future the ServerScheduler may be removed and instead there will be isolated per-plugin sync-task schedulers - but we cannot have every plugin with its own worker pool for memory usage reasons if nothing else.
The following things have changed:
- ServerScheduler: scheduleAsyncTask(), scheduleAsyncTaskToWorker(), getAsyncTaskPoolSize(), increaseAsyncTaskPoolSize() and similar methods have all been removed. Additionally the static \$WORKERS field has been removed.
- Server: added API method getAsyncPool(). This grants you direct access to the server's AsyncPool. Calls to getScheduler()->scheduleAsyncTask() and scheduleAsyncTaskToWorker() should be replaced with getAsyncPool()->submitTask() and submitTaskToWorker() respectively.
this implementation was god-awful bad and it was entirely avoidable to make it this complicated.
This utilizes the fact that pthreads treats static properties as thread-local. AsyncTask local storage now utilizes a \SplObjectStorage stored in an AsyncTask private static field.
Code dependencies can be seen in the code and in the composer.json file. Besides, there are additional third-party libraries used by PocketMine-MP now which are not listed in this section, and I don't plan to maintain it...
Once upon a time, these userland functions were faster than calling builtins, but not anymore. According to my test the Math functions are twice slower in PHP 7.2 with typehints and 50% slower without typehints.
Inlining is slightly faster than using builtins, but the difference is very small - not worth making the code look any more ugly than it does already.
This is the same bug that Entity->getBlocksAround() had, except this actually checks for BB intersections. What this means is that as a result of the bug, one extra layer of blocks is unnecessarily checked on the max sides of the BB.
For example:
Assume you have a BB with maxY -5.5
You're definitely colliding with block -6 (because you're inside it) and you want to check an extra block in case you hit something weird like a fence.
So you want to check _at most_ up to block -5 (inclusive).
Following this maths:
-5.5 + 1 = -4.5
ceil(-4.5) = -4
This causes us to check block -4 unnecessarily. This may be a performance waste - depending on the BB size it could be proportionally a lot of blocks getting unnecessarily checked. This has not been benchmarked.
these are items that do nothing and/or are only used for crafting. As such they are simple to add.
Others will be added later on, but others require extra work and/or reverse engineering which I don't have time for now.
Totem usage can be detected using the MODIFIER_TOTEM constant of EntityDamageEvent.
This does not currently support using the totem in the offhand because offhand is not implemented yet.
The general purpose of this is to split up base damage from modifiers.
- Added methods getBaseDamage(), setBaseDamage(), getOriginalBaseDamage(), getModifiers(), getOriginalModifiers()
- setDamage() renamed to setModifier() and type is now mandatory
- getDamage() renamed to getModifier() and type is now mandatory
- getOriginalDamage() renamed to getOriginalModifier() and type is now mandatory
- Removed MODIFIER_BASE constant
- Constructors now accept: float baseDamage, float[] modifiers instead of just float[] modifiers
Terminal::hasFormattingCodes() should be used instead (this is also portable across threads even if constants aren't inherited by child threads, provided that the child thread has an autoloader available.
Since this is managed by Composer now, it's expected that users should install dependencies appropriately when running from source code. We have a few more dependencies than just RakLib and SPL which are version-critical which are not checked here, and I don't have the taste for adding more version checks here.
A better way would be to automatically detect outdated Composer autoloader and warn that dependencies might need updating, but I'm not sure how to do that off the hop. Users should prefer using prebuilt phars anyway - only developers and/or people who know what they are doing should be running the server from source code.
this is only used in one place, where it's being given floats, and it's 10% faster to use int for this because it won't convert it.
It is also 25% faster to remove typehints and 60% faster to inline it. We really need a proper PHP preprocessor for inlining.
this fixes crashes when PurePerms causes this to be recalculated on player login - the client doesn't like receiving this before StartGame and crashes.
Confining this to post-spawn should not cause any issues since any permission recalculation in login events will be reflected immediately afterwards when the initial command data is sent anyway.
This same bug popped up at 1.1... I don't know why it wasn't fixed properly back then.
this is nearly the same as 1.5.0.0, except the skin packet premium boolean has been dropped.
This isn't production ready yet because the blockID table needs updating (waiting on MrARM to fix his script for that).
Players have a few associated inventories which might need sending nowadays, such as main, armour, offhand (not implemented yet), cursor, crafting (if it ever worked). Under these conditions we should be sending all open windows.
long overdue... this isn't quite as extensible as the original api3/blocks system was, but this is primarily intended to replace Item->useOn(). If plugins want to use it it can be extended later on.
This now utilizes Snooze in order to have the server wake up to process RCON commands ondemand, similar to how the CommandReader thread operates. This is better for performance and response times.
This also makes a few other changes:
- RCON thread will now waste less CPU since it uses a blocking select() with timeout to read
- Following from that, IPC sockets are used to allow interrupting select() from the RCON thread.
- Multiple threads for RCON has been removed (this is entirely unnecessary, reading data from sockets is not CPU-intensive, and a single thread is easier to work with)
in some cases the main thread was trying to signal the server killer to stop before it was even started due to limited resources available for scheduling.
ArrayOutOfBoundsException is not thrown by SPL anymore since the exception handler throwing it was removed by @shoghicp. Regardless, it seems cleaner to to check it properly.
This allows other threads to notify the main thread to wake it up while it's sleeping between ticks, allowing reduction of processing latency.
Currently only RakLib and the CommandReader threads utilize this, but it's planned to extend it to more things in the near future.
CommandReader is now event-driven instead of poll-based - the server will not poll the CommandReader thread for messages each tick anymore.
RakLib utilizes this mechanism to get packets processed without delays to lower latency.
This now adds an extra dependency - `pocketmine/snooze` library contains the meat of the code used for this. See the Snooze repository for details.
pthreads doesn't play well with resources, and this code upsets it. Also, this code is utterly pointless.
The whole of RCON needs burning to the ground...
It is somewhat reasonable to have a function in an event handler which accepts an Event parameter, but is not a handler. For example, multiple event handlers can redirect to the same function to process an event, but this function may not want to receive called events.
There are other ways to get around this, such as making the event handler protected/private, or adding a dummy parameter, but this way is cleaner and more explicit.
Relevant old-repo PR: PocketMine/PocketMine-MP#2143
This allows plugins to soft-depend on other plugins without separating their listeners into a dedicated class for listening to that plugin.
This can be utilized by adding a `@softDepend PluginName` to the event handler's annotations.
If the plugin providing the event does not exist or is not loaded, then the handler will silently not be registered.
If it does exist and the event is not found, the original behaviour applies and an exception will be thrown.
This change should be fully backwards compatible.
Yes, I am not happy about this either. new-versioning has issues, and there hasn't been enough development and testing on it.
I didn't want to delay release to cram in a half-baked new versioning system, and it's ended up delayed anyway and new-versioning is still half-baked.
we're overdue a new release, so here it is.
this was causing unexpected behaviour particularly on burning trees, whereby fire would be unconditionally extinguished if the block below it was removed.
This makes the behaviour match vanilla. This will now allow Fire block itself to handle deletion of itself when the area is not suitable (now that the logic is implemented in Fire for this).
This allows attempting to place in invalid conditions, which is as expected. This will produce the sound and flash as per vanilla, as the fire extinguishes itself.
this happens when a player respawns before their death animation ends. I don't know why, but their bounding box height suddenly becomes zero. This solves the bug by simply resending the height and width properties to viewers on respawn.
Closes#2135.
As of 1.2.13 release, the client now skips the crafting grid step when it crafts with right-click on the recipe book. This means that we can't validate crafting based on the crafting grid contents anymore. The only way to do it now is to use the inputs and outputs calculated by the transaction balance.
Returning false all the time could mean any one of a range of things. Throwing exceptions is better in that it allows us to catch them and see what actually broke.
This is basically how blockstate discovery would actually work in the full-blown system. This maps blocks with unrecognized blockstates to static runtimeIDs not known to the client.
This means that all blocks which don't have corresponding runtimeIDs in the new system will translate to update! blocks instead.
Mojang do this differently: they try to a) match id+meta, if that fails b) match id+0, and if that fails, then replace with update! block runtime ID. I can't do that here because I need to be able to convert both ways. They only need to be able to convert from legacy -> new.
this needs further changes (particularly to Furnace) to stop things abusing NBT for runtime data handling, otherwise performance is going to drop off a cliff.
This allows deleting lots of code, and additionally provides a huge reduction in the compressed size of CraftingDataPacket. Since we don't care about these UUIDs (they are only used in CraftingEventPacket, which is broken and unused in PM) we fill them with zeros instead.
This commit brings in a much-needed rewrite of crafting transaction handling.
The following classes have been removed:
- CraftingTransferMaterialAction
- CraftingTakeResultAction
The following classes have significant changes:
- CraftingTransaction
- All API methods have been removed and are now handled in CraftItemEvent
- CraftItemEvent
- added the following:
- getInputs()
- getOutputs()
- getRepetitions() (tells how many times a recipe was crafted in this event)
- Recipe interface:
- Removed getResult() (individual recipes may handle this differently)
- CraftingRecipe interface
- removed the following:
- matchItems()
- getExtraResults()
- getAllResults()
- added the following
- getResults()
- getIngredientList() : Item[], which must return a 1D array of items that should be consumed (wildcards accepted).
- matchesCraftingGrid(CraftingGrid)
- ShapedRecipe
- constructor now accepts string[], Item[], Item[]
- ShapelessRecipe
- constructor now accepts Item[], Item[]
the requirement for a crafting table is determined by the number of ingredients can fit on the grid (shapeless) or the max height and width (shaped). It's impossible to craft a big recipe with a small crafting table simply because you're not able to put the required resources into the grid.
This now handles the case where there are multiple options which could be taken, and opts for the first result which successfully ties all the actions together. Previously it would be entirely down to chance (ordering) whether the actions would get ordered successfully.
this old code is extremely inefficient. This showed up distinctly in my crafting bruteforce benchmarks, where I discovered that getContents() accounted for the vast majority of the time taken to match shaped recipes.
Since the addition of resetLastMovements(), this code is useless.
Additionally, it doesn't make sense to ignore the first movement, because the first movement still _moves the player_ from point A to point B.
This just causes it to attempt to spam chunk orders prior to the player spawning. It won't succeed, because the render distance is zero.
The other time this could occur is when teleporting into an unloaded chunk, but it's not necessary to continually spam chunk orders in that case, especially since chunk orders are done on teleport anyway.
This prevents unexplained segfaults on accidental event call recursion by limiting the max depth of event call stack to 50. If another event attempts to be called, an exception will be thrown.
* Event handlers always handle subclass events. public static $handlerList no longer required.
* Removed $handlerList declarations
* HandlerList cleanup: Removed HandlerList->handlers and related bake methods
* Removed obsolete Event->getHandlers()
* EventPriority: Added fromString()
* PluginManager: throw exceptions on registering handlers with invalid priorities
This allows specifying a handler of `EntityDamageEvent` which will handle any instanceof it (as per current behaviour), AND also now allows specifying a handler specifically for `EntityDamageByEntityEvent`, which only handles `EntityDamageEvent`.
This was not previously possible due to limitations in the way handlers were registered.
Abstract events may not be handled unless they declare the `@allowHandle` PhpDoc tag.
This is a bad fix for an issue found in one specific use-case. This is redundant because the only places this is used are places where it's guaranteed to be valid, or places where it is checked to be valid anyway.
The Level leak originally noted that led to the creation of this class is something I consider to be a non-issue, because all the heavy things will be cleaned up anyway.
This happened when a block was set into the world with a direct update, when an entry for that block was already present in the changedBlocks map. This fixes the bug by removing the entry from the changedBlocks map to avoid sending outdated block updates in batches.
closes#2106
For some strange reason, using aliases overwrites the original command name instead of coexisting with it. This is rather astonishing behaviour, and probably a bug in the client. However, this workaround is the same thing vanilla does (see /tp in vanilla).
Chunks were used by tiles for a couple of things:
- 1. for coordinates - which can be gotten using bitshifts
- 2. setChanged() - which is unnecessary as seen in the previous commit
Removing this circular dependency was actually remarkably easy to do.
This allows the removal of lots of ugly code, and also exposes lots of similarities with how this update type was handled. This can be further improved in the future to more generically handle cases.
I realized in the process of changing this, that it might actually be simpler to treat to treat scheduled updates and neighbour updates as one and the same. They use the same mechanism for being saved on chunks (TileTicks),
and doing that would make updating only require one queue instead of two.
RedstoneOre: use onActivate() to trigger glowing
this is not technically correct behaviour, but this preserves the current behaviour.
Previously to this, a level would be considered "not generated" if no level providers registered as valid for that directory. This caused astonishing behaviour when the user's world has, for example, a mixture of .mca and .mcr region files - the world would instead get _re-generated_ according to the default level format, which might or might not load the existing regions depending on the format used for generation. This behaviour is utterly absurd.
This changes the behaviour of the generated check to check for a non-empty directory in the given path. Non-empty directories without recognized world files in them are now considered to have an unknown format.
This is necessary because the stupid client constantly spams right-click actions if you carry on trying to eat/throw/whatever the item when cooldown is in effect. Therefore ender pearls would be fired like machine guns without these checks server side.
this was caused by abe5d94d5b because player's lastBlah wasn't getting updated anymore.
Player movement handling really needs cleaning up, but for now this fixes the issue.
save() calls saveChunks() which saves any chunks found to be modified. But chunk unloading does this anyway, so it's better to unload first and then trigger the save mechanism, to avoid saving chunks twice.
This supports vanilla placement of paintings, with overlap and collision checking.
Paintings are removed when a block is placed inside them or if any of their supporting blocks are removed.
As per vanilla, a random painting is chosen from the largest subset that will fit into the given space.
it appears that errors are occurring in the exception handler when handling corrupted regions, leaving regions in the provider index with incomplete location tables. This causes strange-looking errors later down the line.
This moves the region assignment to the end of the condition to avoid leaving incomplete/corrupted regions in the location table when errors occur.
This now removes logging from the level providers (for the most part) and replaces it with exception throws and catches. The implementation using the providers should catch these exceptions if they are thrown.
closes#2047
Since the player list already indexes players by UUID, it's simple to just use that for fetching the player.
A possible future improvement could be to allow fetching an _offline_ player by UUID, but no capability to do that is yet available.
This function is not declared in any useful places (like the CommandSender interface) and it is not present in Player (!!!). Additionally, an is-player check is better done with an instanceof so that type safety is enforced and IDEs can give auto-complete.
This is a BC break, but this is such a pointless function that it's probably not even worth mentioning.
This is completely unnecessary and adds extra complexity for no good reason. Maybe it was used historically, but nowadays it is only used to identify players to send async-prepared batch packets to.
There are two alternative ways to do that:
1. use spl_object_hash() as the targets array in CompressBatchedTask
2. use ServerScheduler's object storage to retain references to the Player[] array.
I've opted for the second method.
Removing these identifiers allows great code simplification in removePlayer() and removes the need for those old stupid hacks.
This also includes a backwards-compatibility break by removing the $identifier parameter of Server->addPlayer().
The child powershell is a workaround for an unidentified bug which causes colours to get messed up after using git in the same console window. However, loading profiles on the child is a major slowdown when starting the server, and for no good reason.
https://bugs.php.net/bug.php?id=75992
When plugins do time-limited bans and users enter stupid time values, a shitty bug in ext/date gets triggered, but only when reading the ban entries from disk. DateTime->format() is able to produce formatted strings which have more than 4 digits in the year, which are then considered invalid. This works around it by trying to parse a formatted version on the fly to ensure that it is valid.
This also cleans up and improves ban list loading and handling.
This cleans a lot of mess out of the bootstrap file, and also has the added bonus that threads which do not inherit functions can now get access to them by autoloading Utils.
Currently an ItemBlock is created for every Block requested, but this will need to change in the future (for Anvils because they have stupid bitshifts on the meta instead of a nice bitmask). This allows registering items in the ItemFactory with IDs lower than 256 and having them recognized.
This allows retrieving the name of an item without the custom name being plastered over the top. This will also allow weird things to have special functions for their names.
This convention is used throughout the code to allow plugin developers to alter the behaviour of the event. In this case, it would instead produce unexpected behaviour when the event is not cancelled by a plugin.
Since we don't use the PEAR-style namespacing convention, there's no reason to use PSR-0 autoloader.
We don't quite follow PSR-4 conventions because there is still a pocketmine subdirectory, but changing this might pollute the git history, so I'm wary of changing it.
These are never called accidentally, or at least it's highly unlikely to do so. It might be reasonable to throw exceptions for this, but for the meantime they are redundant - extra indentation for no good reason.
This also removes the $force parameter from BlockFactory::init().
Wanting initialized item factory does not require initializing the creative inventory. This is often useless and unwanted extra baggage (when this is used on threads for example).
This code is no longer necessary, because entities are constructed with a Level instead of a Chunk since API 3.0.0-ALPHA4. This means that they will not get allocated in the wrong chunk at runtime after having been saved on the wrong chunk by something else (such as an older version of PM). They will instead be allocated in a chunk selected by bitshifting their coordinates.
This is necessary to be able to fix#1789 without causing entities affected by the infamous bitshift-on-floats bugs to inexplicably vanish.
* Revert "Revert bad duct-tape fix that broke lots of other things"
This reverts commit 4a4900e5e7.
Player: Perform respawn actions when joining while dead
This fixes exploits related to #1567 by calling respawn logic on join when the player has zero health.
This is a shitty fix and doesn't solve the actual issues described in #1567, but it's a simple solution for the exploits related to it.
This also removes a cyclic dependency between TextFormat and Terminal, meaning that TextFormat is now standalone without any external dependencies.
This is also an API break. Beware all ye who wander here, master = bleeding-edge!
TAG_String has a UTF-8 payload, which makes it more expensive to work with. Also, skins can contain bytes which are not valid UTF-8 characters and will therefore be treated as corrupted by external tools.
Additionally a TAG_String can only hold 32767 bytes, which might become a problem in the future.
A TAG_ByteArray can hold up to 2GB of data, and there is no character encoding restrictions on it.
This fix doesn't fix existing data, but it will prevent the bug happening in the future by capping the length of strings to 32767 bytes, and throwing an exception if too long.
This extension hasn't been maintained in 4 years and it doesn't make sense to update it to PHP 7, since :shoghi: just dumped a blob of PHP into zephir. It's not worth the hassle of updating.
I prefer to modularise and then C-ify modules, so that they can be reused on their own.
SIGKILL constant is defined by pcntl, not by posix. If pcntl is not compiled then bugs can occur when trying to kill() the server (such as during a crash).
Closing the command window immediately when an error occurs is particularly unhelpful. This keeps the command window open so that the user can see what went wrong.

Exceptions occurring early in the start sequence (before BaseLang is initialized) will result in the server hanging and not killing process as expected. This works around that issue.

If you are on Linux, you can use `wget -q -O - http://cdn.pocketmine.net/installer.sh | bash -s - -v Alpha_1.3.12` to update. If you are on a MacOS, use `curl -sL http://cdn.pocketmine.net/installer.sh | bash -s - -v Alpha_1.3.12`
**THIS IS A PRE RELEASE. Do not use it in production unless you are sure you know what you are doing.**
Only changes since the 1.6dev tag will be documented here. Changes between 1.4.1 and 1.6dev are far too extensive to document effectively.
## Core
- New RNG, based on XorShift128 from the php-random library. This fixes issue with repeating terrain on 32-bit systems. _Note however that new generation into existing worlds will not be seamless._
- Block and Item IDs have been moved to interfaces for better consistency
- Better method for synchronisation of client/server time (less packet spam)
- Utils::getRandomBytes() has been deprecated in favour of php7's random_bytes() function.
-`<player>.dat` saving/reading can now be disabled in `pocketmine.yml` (set `player.save-player-data` to `false`)
## Gameplay/game features
- Added Flower Pots
- Containers can now be opened in creative
- Trapdoors can now be placed without a supporting block
## API
This release has API changes, bumping the version to 2.1.0.
### Entity metadata (0.16)
Many changes have been made to entity metadata. Many true/false data properties are now entity status flags, such as NoAI, NametagVisible and various others. Entity status flags can be set using:
**Breaking** changes are detailed here. Additions are not documented. https://gist.github.com/dktapps/76b291b7a861762b54f7a8b834389883
**NOTE: It's strongly recommended to use provided API methods where possible instead of tampering with metadata directly.**
### AsyncTask API additions
- Main thread local storage: Developers can pass any data including objects to the constructor of AsyncTask such that the data can be retrieved after the AsyncTask completes using the new `AsyncTask::fetchLocal()` method, or use the `AsyncTask::peekLocal()` method to get the data without removing it.
- Progress updates: Developers can use the new `AsyncTask::publishProgress() method and override`AsyncTask::onProgressUpdated()` to handle AsyncTask progress information in the main thread.
Refer to #1 and #100 for details.
### WeakPosition
WeakPosition was added in 1.6.1 to fix bugs with unloading levels which have player spawn points set in them. This type of position holds a level ID instead of a direct reference. Use this when your position may outlive the level it is in.
### Removal of Item/NBT circular dependency
Refer to #121 for details.
### Other
- Added Player->sendWhisper() (#73).
- Removed LargeExplodeParticle due to incorrect name - use HugeExplodeParticle. Added HugeExplodeSeedParticle and BlockForceFieldParticle (7314aaf7f7bdae582f674c085c7ae879985bf847)
## Fixes
- Fixed the infamous hotbar spaz bug
- Creative/spectator inventory now sends correctly
- Fixed spectator flight controls
- Fixed issues with items going past the end of the regular inventory
- Fixed furnace client crashes
- Fixed inventory windows for anvils and enchanting tables
- Fixed kicked for walking on lily pads (#blameshoghicp)
- Fixed a nasty entity-related memory leak on chunk unload
- Fixed sleeping players floating above beds and teleportation of sleeping players.
- Fixed a bug in Level::updateAround() where only one block would update
**While this release is nominally not an alpha, it is still not feature complete and does not include all gameplay features. Please do not create issues for missing gameplay features.**
This build has breaking API changes.
This release is the first to use the new merged versioning system. The PocketMine-MP version and the API version are now one and the same.
Please use our issue tracker to report bugs.
# 3.0.0
## Core
### General
- This release introduces a new dependency library called `Snooze`, which PocketMine-MP utilizes for managing notifications between threads. This library is currently utilized by command reading, RCON and RakLib, allowing faster response times to commands, reduced network latency, and better performance due to lack of need for polling.
- Fixed race condition causing `ServerKiller` to sometimes kill the server for no reason on shutdown.
These libraries may individually have changes which are not recorded here. See their independent repository releases for their changelogs.
### Async pooling
- Async workers are now started dynamically when they are needed only, instead of being started immediately on startup. This allows reducing idle memory usage.
- AsyncPool now appropriately shuts down the workers when instructed to, instead of leaving it up to the ThreadManager to clean it up. This eliminates debug messages of shutting down async workers on server shutdown.
- Default maximum async worker memory limit has been lowered from 1024MB to 256MB.
- Async workers are now started using the options `PTHREADS_INHERIT_CONSTANTS | PTHREADS_INHERIT_INI`, which reduces idle memory wastage and works around some bugs in pthreads.
### Entities
- Fixed entities not being despawned when flagged, if they weren't scheduled for an update.
### Levels
- Seed handling is now always consistent between `pocketmine.yml` and `server.properties`.
- Fixed generation bugs in imported LevelDB worlds where the classpath was saved into level.dat.
- Generators for levels are no longer created on the main thread, reducing memory usage.
### Plugins
- Plugin data is now stored under `<data dir>/plugin_data` by default on new installations, instead of in `<plugins dir>`. This behaviour does not affect existing installations by default - if you want to enable it, set `plugins.legacy-data-dir` to `false` in `pocketmine.yml`.
### RCON
RCON has been almost completely rewritten in this release.
- Now event-driven (using Snooze) instead of poll-based, improving performance.
- Fixed segmentation fault when stopping the server with RCON enabled.
## API
**WARNING: Dependency library API changes are not listed here. See their individual release notes for changes (linked above in the Core section).**
### API versioning changes for plugins
The way that the API versioning is done has changed. Now the API version is synonymous with the PocketMine-MP version.
Plugin compatibility is determined by the following:
- Take the base version, and strip any metadata (everything after the `+` sign, for example `3.0.0+dev.1191` becomes `3.0.0`).
- Assert that:
- The major versions is the same
- The server's minor version is greater than or equal to the plugin's
- The server's patch version is greater than or equal to the plugin's
Currently there is no support for locking version by metadata, although this could be implemented if it is a wanted feature.
### General
-`Server->getCodename()` and `\pocketmine\CODENAME` have been removed.
- Added API method `Server->getTickSleeper()`, which returns a `\pocketmine\snooze\SleeperHandler` instance.
-`Server->getIp()` now returns `0.0.0.0` if not set.
### Block
- Added `Block->getXpDropForTool()`.
### Entity
- Calling `scheduleUpdate()` on an `Entity` after it has been `close()`d will now cause an exception to be thrown.
-`Entity->motionX`, `Entity->motionY``Entity->motionZ` have been removed in favour of an `Entity->motion``Vector3` field. This also applies for the `lastMotion` fields.
-`Entity->isInsideOfWater()` has been renamed to `isUnderwater()`.
### Events
- Added support for `@softDepend` annotation on event handlers, which allows the event handler to not be registered if the dependency plugin is not loaded.
- Added support for `@notHandler` annotation for `Listener` methods to indicate that such methods are not event handlers.
- Typehints have been applied to the events API to PHP 7.2 standards.
- Fixed preventing effect expiry using `EntityEffectRemoveEvent` not being reflected on the client.
-`EntityDamageEvent` API has significant changes. The general purpose of this is to split up base damage from modifiers.
-`setDamage()` renamed to `setModifier()`, and type parameter is now mandatory
-`getDamage()` renamed to `getModifier()`, and type parameter is now mandatory
-`getOriginalDamage()` renamed to `getOriginalModifier()`, and type parameter is now mandatory
- Removed `MODIFIER_BASE` constant
- Constructors now accept: `float baseDamage`, `float[] modifiers` instead of just `float[] modifiers`
- Added `BlockBreakEvent->getXpDropAmount()` and `BlockBreakEvent->setXpDropAmount()`.
### Inventory
-`InventoryTransaction->getCreationTime()` has been removed.
-`EntityInventoryChangeEvent` and `EntityArmorChangeEvent` are no longer fired during entity inventory intialization.
### Item
- Methods `isPickaxe()`, `isAxe()`, `isSword()`, `isShovel()`, `isHoe()`, `isShears()` have been removed. These should be replaced with `instanceof` checks for the relevant classes.
- Removed `Item->useOn()`. This has been superseded by new methods used for handling durability changes.
- Added hooks `Item->onDestroyBlock()` and `Item->onAttackEntity()`. These are called when a player uses the item to destroy a block or attack an entity respectively. This is used in the core code for updating durability.
-`Item->pop()` now accepts an optional count parameter.
-`Enchantment` now has separated primary items (which can be enchanted directly) and secondary items (which can be enchanted on an anvil). The constructor of `Enchantment` has been updated to reflect this.
- Removed `Enchantment->getSlot()` and `Enchantment->hasSlot()`.
- Added `Enchantment->getPrimaryItemFlags()`, `Enchantment->hasPrimaryItemFlag()`, `Enchantment->getSecondaryItemFlags()` and `Enchantment->hasSecondaryItemFlag()`
### Level
-`Biome` classes have been moved to `pocketmine\level\biome` namespace. This is in preparation for future work on Levels which requires biome information (such as weather conditions).
-`WeakPosition` has been removed.
- Added `Level->getBiome()`.
-`Level->getSafeSpawn()` now always returns a `Position` instance.
-`Level->getBlockExtraData()` and `Level->setBlockExtraData()` have been removed (as well as their associated `Chunk` methods).
-`ChunkManager->isInWorld()` now accepts integers instead of floats.
- Added `SubChunkIteratorManager->invalidate()`.
#### Generator
-`BiomeSelector` has been refactored to make it simpler and more robust.
- Generator-management methods `registerDefaultGenerators()`, `addGenerator()`, `getGeneratorList()`, `getGenerator()`, and `getGeneratorName()` have been moved from `Generator` to a new `GeneratorManager` class.
- Static noise functions in the `Generator` base class have been moved to `Noise` instance methods.
- Added static method `Generator::convertSeed()`, which converts an int or string into a numeric seed for generation.
### Network
-`SourceInterface->process()` no longer returns a value.
### Plugin
-`PluginBase->getResources()` now returns an associative array where the index is the path to the resource relative to the plugin's `resources` directory.
-`PluginLoader`s have been almost completely rewritten to make them simpler and more robust.
-`PluginManager->registerInterface()` does not return anything, and now accepts a `PluginLoader` instance instead of a `string`.
-`PluginLoader`:
-`getPluginFilters()`, `enablePlugin()` and `disablePlugin()` are removed.
-`loadPlugin()` responsibilities are now solely confined to doing whatever is necessary to make the plugin's classes visible by the server, and does not emit log messages or check for data directories.
- Added method `getAccessProtocol()` which determines what prefix to apply to the plugin path to access the files inside it (for example `phar://`).
-`PluginBase->init()` and `PluginBase->isInitialized()` have been removed.
-`Plugin` interface now declares a signature for the constructor which implementations must comply with.
-`Plugin` interface now declares `setEnabled()`.
- It is now possible to create a custom `Plugin` implementation without requiring a custom `PluginLoader`.
### Scheduler
This release features major changes to how plugin task scheduling works.
- Removed `Server->getScheduler()`. All plugins now have their own scheduler which is accessible using `Plugin->getScheduler()`. Aside from being syntactically more concise and pleasant, this also allows much more effective management of tasks when plugins are disabled.
- Removed `PluginTask` class, because it's now unnecessary. Previously it was required to allow the server to delete tasks associated with a plugin when the plugin was disabled. With plugin-owned schedulers, this is no longer a requirement. Plugins may now utilize the `Task` class as a base if they like.
- Added `Server->getAsyncPool()`. Since the global scheduler does not exist any more, it does not manage the server's `AsyncPool` any more. Additionally, `ServerScheduler` was previously bloated by a lot of `AsyncTask` related methods, which are now not necessary because direct access to `AsyncPool` is granted instead.
-`ServerScheduler`:
-`ServerScheduler` has been renamed to `TaskScheduler` since it is now a general-purpose task scheduler which is non-dependent on the user. This allows much greater flexibility and also makes it possible to unit-test.
- All `AsyncTask`/`AsyncPool` related methods have been removed - the task scheduler does not manage the async pool anymore.
- Calls to `Server->getScheduler()->scheduleAsyncTask()` should be replaced with `Server->getAsyncPool()->submitTask()`.
- Calls to `Server->getScheduler()->scheduleAsyncTaskToWorker()` should be replaced with and `Server->getAsyncPool()->submitTaskToWorker()`.
### Tile
- Calling `scheduleUpdate()` on a `Tile` after it has been `close()`d will now cause an exception to be thrown.
- Tile NBT is now ephemeral and is not retained after creating the tile.
-`Tile->namedtag` has been removed.
-`Tile->saveNBT()` now returns a new `CompoundTag` containing saved data.
- Added new protected methods `Tile->readSaveData()` and `Tile->writeSaveData()`. These should be overridden to add or read tile-specific data, instead of overriding `saveNBT()` and `__construct()`.
### Utils
- Added `MainLogger->getFormat()` and `MainLogger->setFormat()` to allow manipulating console output format.
## Gameplay
### General
- Fixed a range of block collision issues stemming from off-by-one errors when fetching areas.
### Blocks
- Fixed a crash which occurred when leaving a bed which was broken and replaced during sleep.
- Fixed dark oak and acacia saplings growing into oak trees - now they will not grow at all (they need to be implemented).
- Saplings now take light level into account when trying to grow.
- Ores and other blocks now drop experience when broken with an appropriate tool.
### Entities
- Fixed dropped items not being correctly destroyed by fire, cacti and other damage sources.
### Generation
- Grass no longer generates as the top layer of ground cover in river biomes.
- Ocean biomes now use gravel instead of grass+dirt for ground cover.
- Reduced maximum elevation of plains biomes to make them less bumpy.
- Snow layers and other can-be-flowed-into blocks no longer generate underwater.
### Items
- Buckets are no longer able to delete any block by replacing it with water.
- Dried Kelp, Bleach, Nautilus Shell and Heart of the Sea items are registered (although crafting recipes for these are not yet available).
- Implemented `Vanishing` enchantment.
- Implemented Totems.
### World
- Fixed explosions sometimes leaving behind air blocks with non-zero damage values.
# 3.0.1
- Fixed error when players move things around in the crafting grid after plugins cancel `PlayerInteractEvent` on crafting tables.
# 3.0.2
- Fixed memory dumps not showing private properties of parent classes.
- Fixed a memory leak when cancelling all tasks in the `TaskScheduler`.
- Fixed scheduled task timings showing `Unknown` as the plugin name.
# 3.0.3
- Fixed possible crash in Sign when placed by a plugin.
- Fixed slightly-damaged and very-damaged anvils dropping incorrect items.
-`Living->applyPostDamageEffects()` is no longer called if the mob died from an attack.
- Cooldown for mob attack is now reset prior to applying post-damage effects.
- Added constant `ItemIds::MUTTON` to resolve crashes using PC worlds.
- Fixed emerald ore not dropping XP when broken with a valid tool.
- Fixed mobs getting crazy vertical knockback if attacked while airborne.
- Fixed XP orbs continuing to follow dead players.
# 3.0.4
- Fixed RCON spamming the console when a client does not disconnect correctly.
- Fixed dropping chunk cache unnecessarily when no blocks need to be updated on a chunk.
- Fixed outdated block updates getting sent on chunks replaced using `setBlock()`.
# 3.0.5
- Fixed not being able to place blocks where a player died and has not yet respawned (#2265).
- Fixed mob death animation not being played when `Entity->kill()` is called directly or `/kill` is used.
- Fixed viewers of different halves of double chests not seeing changes made by viewers who opened the other half (#2261).
- Fixed bugs setting items into wrong indexes when double chest halves have differently sized inventories.
- Fixed `getConfig()` crashing when called when the plugin's data directory doesn't exist.
- Fixed a possible exploit with keychain signing for XBL login.
# 3.0.6
- Fixed invalid keys in `.properties` config files being considered as invalid strings.
- Fixed whitespace between key and value `key = value` being invalid in `.properties` config files.
- Fixed a bug in exception message when an invalid permission type is written for a command in plugin.yml.
- Properly fixed newline issues when parsing event handler annotations - `@notHandler` will now work as expected when CRLF line endings are used.
- Fixed `PluginManager->registerEvents()` registering functions as event handlers declared by parent classes which are not `Listener` instances (#2293).
# 3.0.7
- Fixed setting spawn points in un-generated chunks causing the player to fall out of the world.
- Fixed spawn protection deactivating when there are no ops set (this was an unwanted/unexpected feature, so it's considered a bug).
- Fixed cursor items not getting dropped when closing the inventory or dying.
- Fixed more issues with blocks with invalid metadata appearing as update! blocks.
-`Entity->setNameTagAlwaysVisible()` now works (although nametags will still not be shown if the entity is invisible, due to a behavioural change in Minecraft PE).
- Fixed errors passing zero motions to projectiles in some cases.
# 3.0.8
- Fixed player on-ground state not updating when moving horizontally. This allowed fly hacks with the built in anti-cheat, and also affected some third party anti-cheat plugins due to the effect on `inAirTicks`.
- Fixed knockback. PC 1.9-style knockback was mistakenly introduced in 3.0.3. This has now been reverted back to the old 1.8-style behaviour.
# 3.0.9
- Cleaned up odd behaviour of `/kill` due to old broken code.
- Fixed patch level check for plugin APIs not allowing lesser patch versions on greater minor versions.
- Fixed `/timings paste`. This now reports directly to the timings host instead of using Ubuntu Pastebin.
- Minor code cleanups in various places.
- Zip resource packs will now give slightly less useless errors - errors for broken manifest have been separated from those with fields missing, and now reports why decoding failed if it failed.
# 3.0.10
- Syntax error crashdumps will no longer be reported to the crash archive.
- Chunk sending is now fault-tolerant. Before this release, any error on a worker during async chunk sending (such as memory errors caused by pthreads) would cause that chunk to never get sent, resulting in invisible and missing chunks. Levels will now attempt to retry chunk prepare when a task crashes, which should fix most invisible chunk bugs.
-`MainLogger` now logs exception stack traces in a synchronized block to ensure that they are coherent when log messages are emitted from multiple threads at once.
-`AsyncTask->isCrashed()` now returns `true` if a fatal error occurred during the task execution.
# 3.0.11
-`DropItemAction` will now consider itself invalid if attempting to drop a null item.
- Fixed leaking globally broadcasted Level packets when no players are on the server.
- Fixed title bar not being cleared on server stop on some terminals.
- Fixed `FallingBlock` saving corrupted data.
- Fixed the structure of `GuiDataPickItemPacket`.
- Cleaned up some code in `OfflinePlayer`.
- Splash potions no longer apply effects to dead (but not yet respawned) players.
- Coal ore no longer drops XP when mined with a silk touch tool.
- Item entities now cannot be picked up when a negative pickup delay is used.
# 3.0.12
-`Config` keys which are considered bools by YAML 1.1 will no longer be transformed into 1 or 0.
- Fixed painting motives not getting saved.
- Fixed cacti spewing items when placed in some invalid locations.
- Fixed entity fire damage not applying in the void.
- Fixed entities not getting updated appropriately in some conditions.
Plugins compatible with any previous 3.x.y version will also run on this build and do not need API bumps. Plugin developers should **only** update their required API to this version if you need the changes in this build.
**This build contains changes to the **protocol** which are not covered by the API version. To lock your plugin to a specific protocol version, declare the `mcpe-protocol` attribute in your `plugin.yml`.

This is a minor feature release, including support for Minecraft Bedrock 1.6.0, some new minor gameplay features and some API deprecations and additions.
### Note
Plugins compatible with any previous 3.x.y version will also run on this build and do not need API bumps.
However, some API features have been deprecated in this version. Plugin developers do not need to do anything about these deprecations immediately, however they may raise harmless warnings if used.
Features marked **`@deprecated`** are **recommended** not to be used, but will continue to work for any future 3.x.y versions. They will be removed in the next major release (4.0).
# 3.2.0
### Core
-`Level` generators are now registered only when needed instead of as soon as a worker starts. This drastically reduces memory consumption on servers with lots of workers.
- Async workers are now garbage-collected along with everything else on the default schedule. Idle workers with 0 queued tasks will be shutdown and removed from the pool to reduce memory usage.
- UPnP error messages are now more informative of troubleshooting steps.
- Errors are no longer caught in cases where they are unrecoverable.
### API
#### Entity
- Arrow pickup mode can now be controlled via `Arrow->setPickupMode()`. This accepts one of three `Arrow` constants: `PICKUP_NONE`, `PICKUP_ANY`, `PICKUP_CREATIVE`.
- Added new API methods `Projectile->getBaseDamage()` and `Projectile->setBaseDamage()`.
- Added new API methods `Entity->getScoreTag()` and `Entity->setScoreTag()`.
#### Events
- The `Listener` interface has now received in-depth documentation about its behaviour and uses. See the top of the `Listener` class to read it.
- It is now possible to declare `@ignoreCancelled` on an event handler without specifying `true` or `false`. If no value is found, `true` will be assumed.
-`ServerCommandEvent` and `RemoteServerCommandEvent` are now **`@deprecated`** and their usage discouraged. A new generic `CommandEvent` has been introduced in its place, which allows capturing commands from any type of command sender. This was done in response to difficulties of code duplication when wanting to intercept commands from both console and players.
-`EntityDamageEvent`
- Added `MODIFIER_WEAPON_ENCHANTMENTS` constant for attack damage bonuses due to enchantments like Sharpness.
- Added new API methods `getAttackCooldown()` and `setAttackCooldown()` to allow controlling Living entities attack cooldown times (default 10 ticks).
-`PlayerDeathEvent`: Added new static method `deriveMessage()`.
-`PlayerKickEvent`: Added new method `setReason()`.
#### Forms
- Added a new `pocketmine\form\Form` interface. Implementing this interface permits custom form implementations to make use of `Player->sendForm()`, eliminating the need to handle packets directly and also solving the form ID collision problem.
#### Items
-`Item` and `ItemFactory` now support negative item IDs (needed for future extended blocks support).
- Updated `ItemIds` interface with new constants.
#### Permission
- Added a new `PermissionManager` class which encapsulates all of the permission-management functionality originally bloating `PluginManager`. The API is identical to that of `PluginManager`'s permission API. All methods moved to `PermissionManager` have **`@deprecated`** redirects remaining behind in `PluginManager`, which will be removed in the next major release (4.0).
#### Plugin
-`PluginBase->getConfig()` will now automatically save the default config if it does not already exist.
- Plugin data directories will now be automatically created on plugin load, eliminating the need for boilerplate `@mkdir($this->getDataFolder())` calls at the top of every plugin.
#### Tile
-`Tile::createNBT()` will now throw a `BadMethodCallException` when called directly.
#### Utils
-`Utils::getURL()`, `Utils::postURL()`, `Utils::simpleCurl()` and `Utils::getIP()` have been moved to a new `pocketmine\utils\Internet` class. The original methods are **`@deprecated`** and will be removed for the next major version (4.0).
- Removed the ability for `Config` to be asynchronously saved. This was discussed for removal because of various problems that it causes. It was deemed not worth fixing since `Config` saving should not be significant enough to cause problems anyway. See #2298 for details.
#### Server
- Deprecated `level` parameter of `findEntity()`. This parameter was premature optimization. Code using it will continue to work as before.
### Gameplay
#### General
- Air bubbles are now regenerated at the same speed as vanilla UpdateAquatic, instead of instantly when leaving water.
- Implemented Conduit Power effect.
#### Enchantments
- Implemented the following enchantments: Thorns, Sharpness, Knockback, Fire Aspect, Power, Punch, Flame, Infinity, Mending.
#### Items
- Added the following new items: `Scute`
# 3.2.1
- Fixed `VerifyLoginTask` completion bug when players get disconnected prior to the task completing.
- Fixed client crash issue due to outdated runtime ID mappings.
# 3.2.2
- Updated NBT dependency to 0.2.1 to receive bug fixes (see https://github.com/pmmp/NBT/releases/tag/0.2.1).
# 3.2.3
- Errors thrown during level tick will now crash the server instead of spamming the console.
- Fixed arrows despawning too soon after hitting the ground.
- Fixed projectiles despawning before colliding if they were airborne for > 60 seconds.
- Fixed crash related to Flame enchantment when the player shooting the arrow was on fire.
# 3.2.4
- Fixed levels unloaded during an earlier level's tick on the same tick causing a crash.
- PermissibleBase->clearPermissions() now properly unsubscribes from all permissions.
- Fixed incorrect break check for standing torch.
- Fixed drops for brewing stand.
- Fixed block picking brewing stand, bed, double slab, cake, farmland, and mob heads giving the wrong items.
- Fixed blocks not placing correctly when clicking on redstone ore.
- Fixed unknown PC items in tile inventories crashing the server - now they'll be quietly removed instead.
- Fixed server freezing when eating chorus fruit from high altitude.
-`readline` is now disabled by default on Windows and must be explicitly enabled with `--enable-readline` due to thread-safety issues.
- Fixed server crash when trying to use non-implemented splash potions.
- Removed incorrect maximum region file size cap which may have caused some worlds to be incorrectly detected as corrupted.
# 3.2.5
-`Player->sendForm()` now throws a proper exception when failing to JSON-encode `Form` objects given to it.
- Fixed crash when handling later packets in a batch when an earlier packet triggered termination of the player's connection.
- Fixed a race condition causing progress updates in `AsyncTasks` to be lost when published near completion.
- Fixed bad decoding for some packets with unsupported structures.
- Crash dumps no longer report 20 empty lines when an error occurs in `eval()`'d code.
-`pocketmine/nbt` dependency updated to `0.2.2` to fix bugs (see NBT repo for changelog).
# 3.2.6
- Chunk ticking no longer occurs in chunks which have an adjacent unloaded chunks, fixing things like grass ticking triggering unintentional chunk loading.
- Fixed some lighting propagation issues where step count is the same but light level is different.
- Fixed full-chunk light repopulation producing broken lighting when the generator hasn't been registered on a worker.
- Fixed a missing field in `MoveEntityDeltaPacket`.
- Added client-sided rate limiting for crashdump reporting to mitigate involuntary DDoS of the crash archive.
- Fixed a bug in `start.cmd` where quotes would appear around the "couldn't find installation" message.
# 3.2.7
- Added a network-layer check for item NBT size to avoid unexplained client-sided crashes due to length overflow.
- Fixed some desync bugs with double chests when one half of a double chest is unloaded.
- Anonymous class timings will now have a cleaned path for the identifier relative to the plugins directory.
- Anonymous class timings now render correctly on timings.pmmp.io.
- Fixed empty garbage subchunks not getting removed from long-life chunks.
-`start.ps1`, `start.sh` and `start.cmd` no longer recognize source-code installations. Since source-code installations should only be used by developers who know what they are doing anyway, this was considered unwise to keep.
- Fixed a bug/oversight in network chunk preparation that caused chunk prepare to be 4x slower than necessary.
-`Chunk->fastSerialize()` now doesn't serialize useless data (data is omitted based on chunk flags). This significantly reduces the amount of useless data getting copied for generation, population and light calculation.
-`TaskHandler->cancel()` was incorrectly marked as `@internal` in 2014. This has been fixed. Plugin developers should in fact prefer `TaskHandler->cancel()` since it does not require a task to have a circular dependency on its own executor.
Plugins compatible with any previous 3.x.y version will also run on these releases and do not need API bumps. Plugin developers should **only** update their required API to this version if you need the bug fixes in this build.
# 3.3.0
- Compatibility with Minecraft: Bedrock Edition 1.7.0
- Removed compatibility with 1.6.0
-`Player->sendForm()` now throws a proper exception when failing to JSON-encode `Form` objects given to it.

- Fixed a race condition causing progress updates in `AsyncTasks` to be lost when published near completion.
- Fixed bad decoding for some packets with unsupported structures.
- Crash dumps no longer report 20 empty lines when an error occurs in `eval()`'d code.
-`pocketmine/nbt` dependency updated to `0.2.2` to fix bugs (see NBT repo for changelog).

# 3.3.3
- Development build error messages are now more user friendly.
- Fixed meta-only changes not getting saved correctly in `SubChunk->setBlock()`.
- Server will now sleep for up to 120 seconds on a crash if the uptime was less than 120 seconds. This delay is intended to reduce crash archive spam and can be skipped by the user if attended by pressing CTRL+C.
- Fixed preprocessed builds sometimes having `new ` calls treated as function calls.
- Fixed a rare corruption case where player data could be written incorrectly due to a race condition.
-`DataPacket` will now throw errors when attempting to read/write nonexisting fields to make it easier to debug protocol change errors.
# 3.3.4
- Fixed an undefined `DataPacket` field making the previous release unusable.
This is a cumulative minor release featuring performance improvements, memory usage improvements, some new minor gameplay features, some API deprecations and additions, and significant changes to error handling.
### Note
Plugins compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
However, some API features have been deprecated in this version. Plugin developers do not need to do anything about these deprecations immediately, however they may raise harmless warnings if used.
Features marked **`@deprecated`** are **recommended** not to be used, but will continue to work for any future 3.x.y versions. They will be removed in the next major release (4.0).
# 3.4.0
## Core changes
### Performance & memory improvements
- Entity `EXHAUSTION` attribute is no longer synced to the client, which reduces network traffic for survival players and reduces client-sided lag.
- A redundant call was removed from an `Event` call hot path which improves event calling performance by ~15% per event handler executed.
- Light updates are now batched together and executed on the end of each tick. The effects of this are noticeable when setting a large number of blocks in a close area - significant performance improvements should be noticeable for world editors (the ones that didn't disable light updates) and liquid flow is now significantly less expensive.
- Internal enhancements have been made to subchunk light array interfacing to reduce branching and improve access performance.
- Memory usage of most chunks has dropped by ~30-40% due to some improvements to internal storage of unlit subchunks. In real terms this translates to ~30% memory usage reduction for a freshly generated world.
### Error handling
The most notable core change in this release revolves around error handling. Internals have been cleaned up substantially to improve the server behaviour under occurrence of unexpected behaviour. The goal of this is to improve consistency and quality while reducing undefined runtime behaviour.
The following changes have been made:
- Throwing **unexpected**`Throwable`s in the following cases will now cause a server crash (except on network (this will be changed in the future)):
- Event handlers
-`Task->onRun()` on a scheduler
-`AsyncTask->onCompletion()`
-`Command->execute()` and `CommandExecutor->onCommand()`
- Unexpected `Throwable`s thrown during packet handling will now cause the target player to be disconnected with an `Internal server error` message.
### Other changes
- Anti-flight has been removed, along with the `allow-flight` directive in `server.properties`.
- Server language is now controlled by the `language` directive in `server.properties`.
- Added `unban` and `unban-ip` as aliases of `pardon` and `pardon-ip` commands respectively.
## API changes
### Block
-`BlockSpreadEvent` is now fired when lava or water tries to flow into a block.
-`BlockFormEvent` is now fired when lava and water collide to form cobblestone, obsidian or stone.
### Event
- Added new method `Event->call()`. This should be used instead of `PluginManager->callEvent()` in plugins only supporting 3.4+.
-`PluginManager->callEvent()` has been `@deprecated`.
### Level
- Attempting to unload a level during its tick will now throw an `InvalidStateException`.
- Added the following new methods:
-`Level->broadcastPacketToViewers()`
-`Level->getViewersForPosition()`
-`Level->broadcastGlobalPacket()`
-`Level->getChunkAtPosition()`
-`Level->isInLoadedTerrain()`
-`Level->addGlobalPacket()` has been `@deprecated`.
-`LightUpdate` now allows calling `setAndUpdateLight()` for the same position multiple times (needed for light update batching).
### Permission
-`Permission::getByName()` now throws an exception on invalid values instead of silently returning `DEFAULT_FALSE`. This may cause new errors to appear if your plugins had broken permission defaults in `plugin.yml`.
### Player
-`addWindow()` now has stricter validity checks and will now throw exceptions in the following cases: No window IDs left to use, and when a forced window ID collides with an existing window.
- The public `$speed` field has been removed (this was only used by anti-cheat which has now been removed).
### Scheduler
-`AsyncTask->setResult()` has had the `$serialize` parameter removed - now it will automatically serialize (or not) as appropriate.
- Added a new `ClosureTask` which allows concisely scheduling closure execution on a `TaskScheduler`.
-`TaskScheduler->__construct()``$logger` parameter has been `@deprecated` and will be removed in a future major version.
### Server
- Added new method `Server->hasOfflinePlayerData(string $name) : bool`.
-`Server->getAllowFlight()` has been `@deprecated`.
### Utils
-`Config->save()` will no longer catch unexpected exceptions thrown while encoding data.
## Gameplay changes
### Blocks
- Rail connectivity has been implemented for normal, powered, detector and activator rails (but there are currently no minecarts).
# 3.4.1
- Updated crashdump format to be compatible with newest CA. This version or newer is required if you want to be able to submit crashdumps to crash.pmmp.io.
# 3.4.2
-`DataPacket` errors when writing to undefined fields are now more clear.
- Fixed trees being able to overwrite the log parts of other trees.
- Fixed `Player->sendForm()` not working during `PlayerJoinEvent`.
-`Entity->setScale()` now explicitly requires a scale larger than 0.
- Adding invisible `FloatingTextParticle` to a level no longer causes an error.
# 3.4.3
- Fixed burning TNT setting hurt entities on fire when exploding.
-`~` relative coordinates now work in the `/particle` command.

-`Level->setChunk()` no longer deletes tiles and entities when replacing a chunk with itself.
- Fixed a generator race condition causing rare appearances of half-trees on the client in freshly generated terrain.
-`Attribute->resetToDefault()` now fits the default per the min/max bounds, fixing crashes when the bounds are changed to exclude the default.
- Fixed a crash with LevelDB worlds when the `TAG_2D_MAPS` tag is missing.
- Fixed `Utils::getCoreCount()` crashing on some Debian variants.
Plugins compatible with any previous 3.x.y version will also run on these releases and do not need API bumps. Plugin developers should **only** update their required API to this version if you need the changes in this build.

- Fixed `Utils::getCoreCount()` crashing on some Debian variants.
# 3.5.3
- Rewritten documentation of `PlayerPreLoginEvent`, `PlayerLoginEvent` and `PlayerJoinEvent`. They are now much more detailed and no longer misleading.
- Chest items block-picked from double chests will no longer place chests that crash the server when opened.
- Ender chests now make the correct sounds when opening and closing.
- Fixed Sign errors when a buggy or malicious client sent broken NBT with the wrong tags or wrong number of lines.
- Resource packs with comments in the manifest will now load correctly. (MOJANG!!!)
- Placement of unknown blocks is now disallowed. This solves a range of problems with invalid blocks in the world, such as #2260 .
- Errors thrown during `PlayerQuitEvent` or other `Player->close()` errors will now crash the server instead of causing cryptic bugs later on.
- Fixed large chunks (>= 1044476 bytes) becoming corrupted when saved in Region-based worlds - now an exception is thrown instead.
- Reduced the range of exceptions caught during chunk loading. Now, only chunk corruption errors are caught, and anything else will produce a crash.
- Removed catch-all block on chunk saving. Unexpected errors thrown during chunk save will now create a crash.
- Fixed some asserts in packet decode methods.
-`Attribute` now throws exceptions with more informative messages on errors.
- Properly handled some remaining `Uninitialized string offset` bugs when decoding packets.

- Fixed CPU waste ordering chunks for non-moving players.
# 3.5.4
### Fixes
- Fixed server crash when a block update occurs on a torch with corrupted metadata.
- Added a hack to mitigate client-side right-click spam bug. This mostly eliminates spam of `PlayerInteractEvent` on right-click.
- Players will no longer see commands they don't have permission to use in client-sided hints when typing a `/` in the chat window.
-`Event->isCancelled()` and `Event->setCancelled()` now throw more informative errors.
- Errors thrown during a network interface processing will now _actually_ crash the server.
### API changes
- Deprecated `NetworkInterfaceCrashEvent`. Nobody should have been using this anyway.
- Mobs no longer spawn with their heads facing a different direction to their bodies.
- Added a console message when the crash strangler sleeps to stop crash spam.
- Fixed crash in `/title` command `times` subcommand when not enough arguments were passed.
- AsyncWorkers will now not be shut down on GC unless they have not been used for the last 5 minutes. This reduces lag spikes on garbage collection.
- Fixed some unhandled error cases in `AddEntityPacket` encoding.
- Fixed `LogicException` descendents being thrown from some packet decoding methods when encountering bad userdata.
- Player network inventory transaction processing now catches more specific errors.
- Fixed missing decode for `TakeItemEntityPacket`.
- Fixed `/gc` and `/status` truncating memory statistics - now they report to 0.01 precision.
- Global functions and constants are now imported to improve performance.
- Fixed a typo in `pocketmine.command.op.take` description.
- Ice no longer creates water when a creative player breaks it.
-`spawn-mobs` and `spawn-animals` no longer appear in generated `server.properties` on a newly-installed server.
- Added a hack to disable pre-spawn client-sided movement.
- Assertions enabled warning now always shows when `zend.assertions` is not `-1`. The config option to disable this warning has been removed.
-`/status`,`/dumpmemory` and `/gc` are now enabled by default. The `debug.commands` config option has been removed.
- Crash dumps are now more thorough at catching plugin-related crashes.
# 3.5.6
- Fixed `#`-commenting properties in `.properties` files not working.
-`pocketmine.yml` now permits writing `worldname:` with no generation settings in the `worlds` section to force a world to be loaded.
- Fixed Bow force being too low - now it's consistent with Minecraft Java (but not with Bedrock due to a vanilla bug).
- Fixed `recursion detected` bug when encoding crashdumps in some cases.
- Items with too-large NBT tags on network will now have their tags ignored when sending over network, instead of crashing the server. This is a workaround for a protocol bug which will be addressed in a future Minecraft release.
-`/enchant` no longer crashes the server when out-of-bounds enchantment levels are used.
- Fixed some crashes loading Region-based worlds when encountering unexpected EOF.
-`Entity->fireTicks` is now protected (but accessible by magic method for BC purposes) and will now throw an exception when written to if the value is > 32767 or <0.
Plugins compatible with any previous 3.x.y version will also run on these releases and do not need API bumps. Plugin developers should **only** update their required API to this version if you need the changes in this build.
This changelog **does not account for protocol changes**. If your plugin uses the protocol, you're not shielded by API change constraints.

- Fixed Korean command arguments failing to parse.
-`Sign->setText()` and `Sign->setLine()` now enforce that the given text must be UTF-8 text, or an exception will be thrown.
- Sign text is now processed by `mb_scrub()` immediately after loading to remove invalid UTF-8 characters that could crash the client.
-`Human->exhaust()` no longer underflows when the hunger attribute has a fractional value.

- Fixed `RegionLoader` considering a range of invalid chunk coordinates as valid.
- Fixed `RegionLoader` causing region header corruption when an oversized chunk was discovered. This was causing entire regions to be discarded next time they were freshly loaded.
- Fixed performance issue loading old LevelDB worlds (from before MCPE 1.0) due to unmodified chunks being converted every time they were loaded.
- Added new debug messages when a world takes too long (longer than 50ms) to complete a tick.
- Debug messages are now logged when autosave kicks in (with time measurements), which helps debugging unexplained lag spikes.
- Level "auto tick rate" anti-feature and its associated `pocketmine.yml` settings have been removed (see #2665). The settings will persist in old configurations, but will be ignored by this version and future versions.
- The `/save-all` command now outputs custom (non-vanilla) messages informing the user how long it took to complete autosaving.
- The word `level` has been replaced with `world` (where appropriate) throughout language strings and general user interface messages.

- Fixed crash reports caused by folder plugins being reported to the crash archive.
- Fixed spawning entities on unloaded chunks during spawn sequence (possible client crash cause).
- Fixed `/time query` output message.
- Fixed `Server->hasOfflinePlayerData()` being case-sensitive.
- Improved error messages for skin validation in some places.
- Fixed classic stonecutter hardness.
- Fixed iron trapdoors being considered a valid furnace fuel.
- Fixed apple dropping from leaves happening less frequently than intended.
- Fixed tall plants like sunflower being replaceable by the top half.
# 3.8.4
- Plugin load order is now randomised to remove the ability to implicitly depend on filesystem-specific ordering.
- Packet logging in debug messages now uses base64 instead of hex (uses less space).
- Array and string size are now shown in error stack trace logs.
- Stack traces now render a maximum of 80 characters when making string parameters printable.
- Improved documentation for some transaction classes.
- Action order in inventory transactions is now randomised to prevent dependencies on any accidental or client-dependent ordering. Since the transaction system is specifically designed to avoid depending on order, this does not affect any core functionality.
# 3.8.5
- Moved preprocessor to build/ directory.
- Added documentation for `Server->getPlayer()`, `Server->getPlayerExact()` and `Server->matchPlayer()`.
-`server.lock` now contains the PID of the currently-running server.
- PID of server is now reported in the error message when attempting to run two servers from the same data directory at once.
- Fixed sluggish playercount updating on MOTD.
- Added new MultiRecipe UUIDs.
- Added an extra field to `StartGamePacket` to resolve minor incompatibility issues on different 1.11.x patch versions.
# 3.8.6
- Fixed `Entity->isNameTagAlwaysVisible()` not working.
- Log messages are now cleaned of invalid UTF-8 sequences before emitting them.
- Fixed negative integers being considered as strings for world seeds.
- Fixed out-of-bounds access on invalid inventory data in player data saves.
- Fixed crash when custom liquids have flow decays which aren't factors of 4.
- Fixed `Entity->noDamageTicks` not working when the entity had no previous damage cause.
# 3.8.7
- Improved documentation of `Player->getDisplayName()` and `Player::isValidUserName()`.
- Fixed a bug in `SetScorePacket` decoding causing the entry list to always be empty.
Plugins which don't touch the protocol and compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
Plugin developers should **only** update their required API to this version if you need the changes in this build.
**WARNING: If your plugin uses the protocol, you're not shielded by API change constraints.** You should consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you do.
# 3.9.0
- Added support for Minecraft: Bedrock Edition 1.12.0
- Removed compatibility with 1.11.0
## Protocol
- The following classes in the `\pocketmine\network\mcpe\protocol` namespace have been renamed:
- The following classes in the `\pocketmine\network\mcpe\protocol` namespace have been removed:
-`FullChunkDataPacket`
- The following classes in the `\pocketmine\network\mcpe\protocol` namespace have been added:
-`AddEntityPacket` (not to be confused with the old one)
-`ClientCacheBlobStatusPacket`
-`ClientCacheMissResponsePacket`
-`ClientCacheStatusPacket`
-`LevelChunkPacket`
-`RemoveEntityPacket` (not to be confused with the old one)
-`StructureTemplateDataExportRequestPacket`
-`StructureTemplateDataExportResponsePacket`
# 3.9.1
- Fixed resource packs not working on 1.12 clients.
- Fixed some particles displaying incorrectly (some still don't render at all).
- Fixed `Entity->setFireTicks()` with a value of `0` setting the on-fire flag.
- Silenced a debug message which appeared every time a player right-clicked a block.
- Updated constants for `LevelSoundEventPacket`.
# 3.9.2
- Logger warnings for illegal player movements have been lowered to debug.
- TNT explosions now start from the center instead of the base. This fixes unexpected results when TNT is lit on top of obsidian.
- Fixed the `loadbefore` directive in `plugin.yml` sometimes being ignored.
- Fixed `Item->setCustomName()` with an empty string leaving behind an empty tag.
- Fixed incorrect positioning of bucket empty sound.
- Fixed some incorrect tag parsing in `/give` involving quoted numbers.
# 3.9.3
- Fixed a memory leak on async task removal in error conditions.
- Fixed scheduled block updates (for example liquid) triggering chunk reloading. This could cause a significant performance issue in some conditions.
- Fixed some minor cosmetic issues in documentation.
# 3.9.4
- Fixed a memory leak when scheduled updates were pending on a chunk being unloaded.
- Fixed plugin detection in crashdumps. Previously `src/pocketmine` anywhere in the path would cause the error to be considered a core crash, regardless of the preceding path.
- Fixed entity metadata types for 1.12. The SLOT type was removed and a COMPOUND_TAG type added. This change involves changes to internal API which may break plugins. **See the warning at the top of this changelog about API versioning.**
- Fixed random and base populator amounts of trees and tallgrass never being initialized. This bug had no obvious effect, but may have become a problem in future PHP versions.
- The following internal methods have been marked as `@deprecated` and documentation warnings added:
-`Entity->getBlocksAround()`
-`Entity->despawnFrom()`
-`Entity->despawnFromAll()`
- Fixed plugin `softdepend` not influencing load order when a soft-depended plugin had an unresolved soft dependency of its own.
