Resolved Code coverage slowing editor on enter playmode and assembly reload

Using the "editor iteration profiler" i was able to see this information:



This is the stack trace (in case the screenshot is not clear):

Code (CSharp):

1. UnityEditor.dll!UnityEditor::EditorAssemblies.ProcessInitializeOnLoadAttributes()
2. mscorlib.dll!System.Runtime.CompilerServices::RuntimeHelpers.RunClassConstructor()
3. mscorlib.dll!System.Runtime.CompilerServices::RuntimeHelpers.RunClassConstructor()
4. Unity.TestTools.CodeCoverage.Editor.dll!UnityEditor.TestTools.CodeCoverage::CoverageReporterStarter..cctor()
5. Unity.TestTools.CodeCoverage.Editor.dll!UnityEditor.TestTools.CodeCoverage::CommandLineManager.get_instance()
6. Unity.TestTools.CodeCoverage.Editor.dll!UnityEditor.TestTools.CodeCoverage::CommandLineManager..ctor()
7. Unity.TestTools.CodeCoverage.Editor.dll!UnityEditor.TestTools.CodeCoverage::CommandLineManagerImplementation..ctor()
8. Unity.TestTools.CodeCoverage.Editor.dll!UnityEditor.TestTools.CodeCoverage::CommandLineManagerImplementation.ParseCoverageOptions()

I realize 300ms is not much, but this quickly adds up with other plugins and 3rd party packages we have in the project. Also, seems like it might be avoidable, so why not ?

This is the problematic code (getting a list of assemblies):

Code (CSharp):

1.            if (m_IncludePaths.Length > 0)
2.                     m_IncludeAssemblies = AssemblyFiltering.GetAllProjectAssembliesString();
3.                 else
4.                     m_IncludeAssemblies = AssemblyFiltering.GetUserOnlyAssembliesString();

m_IncludePaths is empty, it falls back to getting "user only assemblies"

 

Awesome thanks @Unity-Nikos
