closes#4912
I didn't merge the original PR because this needs to be checked for explicitly registered handlers as well as auto-detected ones from listeners.
This is a step towards #5958.
While it's not actually necessary to add these functions (since people could just use getFile() . "/resources/whatever.yml" instead), this helps preserve the convention of using the `resources` folder, which might be helpful for external tools.
As an example:
stream_get_contents($this->getResource("lang/eng.ini"));
(which is actually incorrect, since it leaks a resource)
can now be replaced by
file_get_contents($this->getResourcePath("lang/eng.ini"));
quite trivially.
getResourceFolder() can be used with scandir() to enumerate resources instead of using getResources(), although getResources() still provides utility in the relativized resource paths.
all this time we've been harping at plugin devs to fix their own leaks, and here's one right under our noses that no one spotted for 10 years ...
this leak is rather common, since it will occur whenever a plugin attempts to save a resource which already exists in the data folder.
This bug was introduced in 2014 by commit 63288346814b7b827f1f7cc7a16419af43bd0bfa.
the only use for this class is to facilitate random runtime plugin loading, and it's not complete even for that purpose.
Since nothing but PM uses pocketmine/classloader anyway, it doesn't make sense to have it outside the core. As with LogPthreads, it's just adding more maintenance work.
due to direct repeated usage of registerEvent() with closures, we've seen some libraries like muqsit/SimplePacketHandler generate very large timings reports, because a new timings handler gets created every time a plugin registers or unregisters a new packet handler callback.
This change fixes the problem by ensuring that any handlers derived from the same function, handling the same event class, will share the same timer.
this could later be expanded to disablePlugin() to make this disable order mandatory, to provide certainty for plugin devs.
Alternative solutions to this include disabling plugins in the opposite order that they were enabled in, but this doesn't allow for random plugin disables. This way seemed to make sense.
closes#3080
If plugins fail to load for some reason, it's highly likely that some critical functionality of the server is compromised. For example:
- if an NPC plugin fails to load, all custom entities added by that plugin will be deleted from worlds
- if a world protection plugin fails, players will be able to grief your otherwise immutable lobby map
- if a worldgen plugin fails, worlds using custom generators won't load
- if a permission plugin fails, players might have access to commands and features they aren't supposed to have
- the list goes on...
This change makes the server commit graceful suicide if any plugin fails to load for error-related reasons, including (but not limited to):
- Incompatible API version
- Missing dependencies
- Invalid plugin.yml
- Invalid main class
Plugins prevented from loading by `plugin_list.yml` are not considered errors and **are not** included in this change. If a plugin is disallowed from loading due to the `plugin_list`, the server will continue to run as if the plugin was not present.
