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.
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.
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 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 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.
- 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)
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.
* 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()`
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.
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.
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.
