From 6883c516e73f55062f27a5f98e306149896c4907 Mon Sep 17 00:00:00 2001 From: Jonas Herzig Date: Wed, 10 Nov 2021 18:21:25 +0100 Subject: Fix mixin injectors not considering mappings from parent classes When remapping the injector target argument (`method`), we used to only look at the mappings for the mixin target class but we also need to consider mappings for its super classes and interfaces. This commit now searches for the target Psi method and then uses the regular remap method for PsiMethod to get its properly mapped name. It still only looks at the target class mappings to determine whether the new name is ambiguous because we do not have access to the remapped target class hierarchy. --- .../kotlin/com/replaymod/gradle/remap/PsiMapper.kt | 70 +++++++++++++--------- 1 file changed, 43 insertions(+), 27 deletions(-) (limited to 'src/main/kotlin/com') diff --git a/src/main/kotlin/com/replaymod/gradle/remap/PsiMapper.kt b/src/main/kotlin/com/replaymod/gradle/remap/PsiMapper.kt index c51b801..a2be57a 100644 --- a/src/main/kotlin/com/replaymod/gradle/remap/PsiMapper.kt +++ b/src/main/kotlin/com/replaymod/gradle/remap/PsiMapper.kt @@ -4,12 +4,15 @@ import com.replaymod.gradle.remap.PsiUtils.getSignature import org.cadixdev.bombe.type.signature.MethodSignature import org.cadixdev.lorenz.MappingSet import org.cadixdev.lorenz.model.ClassMapping +import org.cadixdev.lorenz.model.MethodMapping import org.jetbrains.kotlin.asJava.getRepresentativeLightMethod import org.jetbrains.kotlin.com.intellij.lang.ASTNode import org.jetbrains.kotlin.com.intellij.lang.jvm.JvmModifier import org.jetbrains.kotlin.com.intellij.openapi.util.TextRange import org.jetbrains.kotlin.com.intellij.openapi.util.text.StringUtil import org.jetbrains.kotlin.com.intellij.psi.* +import org.jetbrains.kotlin.com.intellij.psi.search.GlobalSearchScope +import org.jetbrains.kotlin.com.intellij.psi.util.ClassUtil import org.jetbrains.kotlin.descriptors.CallableMemberDescriptor import org.jetbrains.kotlin.descriptors.FunctionDescriptor import org.jetbrains.kotlin.js.resolve.diagnostics.findPsi @@ -106,7 +109,7 @@ internal class PsiMapper( return } - val mapped = findMapping(method) + val mapped = findMapping(method)?.deobfuscatedName if (mapped != null && mapped != method.name) { val maybeGetter = propertyNameByGetMethodName(Name.identifier(mapped)) if (maybeGetter != null // must have getter-style name @@ -130,7 +133,7 @@ internal class PsiMapper( private fun map(expr: PsiElement, method: KtNamedFunction) { val psiMethod = method.getRepresentativeLightMethod() - val mapped = findMapping(psiMethod ?: return) + val mapped = findMapping(psiMethod ?: return)?.deobfuscatedName if (mapped != null && mapped != method.name) { replaceIdentifier(expr, mapped) } @@ -138,7 +141,7 @@ internal class PsiMapper( private fun map(expr: PsiElement, property: SyntheticJavaPropertyDescriptor) { val getter = property.getMethod.findPsi() as?
