Allow loading classes from depending plugin (or how to?) #3139

Open Luluno01 opened 3 years ago

Luluno01 commented 3 years ago

Hi, I am wondering how I can achieve the following:

What I have

What actually happens

Case 1: bundle Kotlin runtime with the third party plugin.

Result: loader constraint violation because the first party and the third party plugin have different instance of the same Kotlin runtime class Continuation.

Case 2: don't bundle Kotlin runtime with the third party plugin.

Result: ClassNotFoundException when loading the third party plugin because its class loader does not load Kotlin runtime from its depending plugin, i.e., the first plugin.

I still can't figure out why this happens only when loading Kotlin runtime classes while loading other classes defined by the depending plugin does not have such problem.

Do you relocate kotlin runtime?

Do you relocate kotlin runtime?

I tried bundling and relocating Kotlin runtime in the third party plugin, which caused MethodNotFoundException. The reason is obvious because it changed to signature of the APIs exposed by the first plugin in the view of the third party plugin. More specifically, the first plugin exposes plugin.foo(kotlin.coroutines.Continuation) while the third party plugin expects plugin.foo(shaded.kotlin.coroutines.Continuation).

Thanks! I am looking into it.

Hi, I exclude Kotlin runtime (and other Maven dependencies) from both plugin jars and BungeeCord downloads the same Kotlin runtime twice (as I can tell from the server log), once for the first plugin and once for the third party plugin. Here are their plugin.ymls for your reference:

The first party plugin (API provider):

name: BungeeSafeguard
main: cyou.untitled.bungeesafeguard.BungeeSafeguardImpl
version: "3.0"
author: Untitled
libraries:
  - org.jetbrains.kotlin:kotlin-stdlib:1.5.20
  - org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.0
  - com.google.code.gson:gson:2.8.7
  - io.ktor:ktor-client-core:1.6.0
  - io.ktor:ktor-client-cio:1.6.0

The third party plugin (API consumer):

name: RESTful-BSG
main: cyou.untitled.restfulbsg.RESTfulBSG
depend:
  - BungeeSafeguard
version: 1.0
author: Untitled
libraries:
  - io.ktor:ktor-server-core:1.6.0
  - io.ktor:ktor-server-netty:1.6.0
  - ch.qos.logback:logback-classic:1.2.3

I noted I shouldn't re-declare the dependencies so I didn't declare Kotlin runtime. Also, I have declared the plugin dependency.

And here is the server log:

It seems the class loaders of two plugins loaded their own instance of Kotlin runtime from the same underlying jar file.

BTW it is weird to me that the dependent plugin gets enabled before its depending plugin. Am I doing anything wrong here?

Oh wait let me check the first link...

Janmm14 commented 3 years ago

Declaring plugin dependencies in bungeecord is done with depends and not with depend. This will fix all your problems. Make sure you remove libraries defined in BungeeSafeguard from RESTful-BSG.

Thanks! IDEA did not warn me about it at all... Now the third party plugin loads after the first but the loader constraint violation is still there. I am looking at https://hub.spigotmc.org/jira/browse/SPIGOT-6486 as it looks like exactly the same problem as mine.

Nope. The "declaring libraries in A only" solution is exactly what I am doing - and the loader constraint violation remains unresolved.

Luluno01 commented 3 years ago

Okay here is the updated plugin.ymls and server log.

The first party plugin (API provider):

name: BungeeSafeguard
main: cyou.untitled.bungeesafeguard.BungeeSafeguardImpl
version: "3.0"
author: Untitled
libraries:
  - org.jetbrains.kotlin:kotlin-stdlib:1.5.20
  - org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.0
  - com.google.code.gson:gson:2.8.7
  - io.ktor:ktor-client-core:1.6.0
  - io.ktor:ktor-client-cio:1.6.0

The third party plugin (API consumer):

name: RESTful-BSG
main: cyou.untitled.restfulbsg.RESTfulBSG
depends:
  - BungeeSafeguard
version: 1.0
author: Untitled
libraries:
  - io.ktor:ktor-server-core:1.6.0
  - io.ktor:ktor-server-netty:1.6.0
  - ch.qos.logback:logback-classic:1.2.3

The problem is likely that the library loader also loads transitive dependencies and so RESTful-BSG in the end still got same libraries as the dependant plugin.

This seems to be a bug in bungeecord.

Any suggested workaround? Should I wait for the patch, or do something like declaring all transitive dependencies in the first plugin?

Janmm14 commented 3 years ago

You could move the library statements from the RESTful-BSG to the BungeeSafeguard plugin, this should do the trick.

Yes, this works. Thanks! Nonetheless I will wait for official fix for this since I can't predict what dependencies the third party plugins would need.

Hi, any plan for fixing the transitive dependency problem? I am looking forward to a graceful fix so that I can release my new plugin update...

I am not sure if you are also considering the version collision problem. In my view a plugin must adapt itself to the plugin it depends on, rather than the other way around. I guess it is quite reasonable to just make the class loader of a plugin a parent loader of all other plugins that depend on it - the child plugin must have known what versions of libraries the parent plugin is using. In case of version collision (which is predictable by the depending plugin), the depending plugin should shade and bundle the corresponding libraries.
