Fix internal query violations and update test expectations for K2

- Make registerExtractorExtension protected (called from subclass) - Change codeQlExtensionReceiver from var to val (setter unused) - Update integration test expected files for K2 behavior: - Add DB-CHECK.expected for known K2 cross-extractor consistency errors - Update result expectations for K2 type resolution differences - Update language test expected files (pathsanitizer, CWE-312): - K2 resolves Path.toString() and CharSequence.toString() with different callable IDs than the Java extractor, causing callableBinding consistency errors and lost taint flow results These are pre-existing K2 issues documented in github/codeql-kotlin-team#196, originally worked around by pinning tests to -language-version 1.9 in PR #16554 (May 2024). Kotlin 2.4.0 drops 1.9 support, forcing us to accept these known K2 differences. Verified: the same DB-CHECK errors occur with the released CodeQL CLI (v2.23.9) and Kotlin 2.3.20 when using -language-version 2.0, confirming these are K2 behavioral differences unrelated to our 2.4.0 extractor changes.

Anders Fugmann	d0e652159e	Fix internal query violations and update test expectations for K2 - Make registerExtractorExtension protected (called from subclass) - Change codeQlExtensionReceiver from var to val (setter unused) - Update integration test expected files for K2 behavior: - Add DB-CHECK.expected for known K2 cross-extractor consistency errors - Update result expectations for K2 type resolution differences - Update language test expected files (pathsanitizer, CWE-312): - K2 resolves Path.toString() and CharSequence.toString() with different callable IDs than the Java extractor, causing callableBinding consistency errors and lost taint flow results These are pre-existing K2 issues documented in github/codeql-kotlin-team#196, originally worked around by pinning tests to -language-version 1.9 in PR #16554 (May 2024). Kotlin 2.4.0 drops 1.9 support, forcing us to accept these known K2 differences. Verified: the same DB-CHECK errors occur with the released CodeQL CLI (v2.23.9) and Kotlin 2.3.20 when using -language-version 2.0, confirming these are K2 behavioral differences unrelated to our 2.4.0 extractor changes.

Anders Fugmann	f3037d68ca	Kotlin: Update integration tests from -language-version 1.9 to 2.0 Kotlin 2.4.0 no longer supports -language-version 1.9. Update all integration tests that explicitly pass this flag to use 2.0 instead. Also update the extractor_information_kotlin1 expected output since -language-version 2.0 causes the extractor to report 'Uses Kotlin 2: true'.

Anders Fugmann	557f904e22	Kotlin: Drop support for Kotlin 1.x language versions Kotlin 2.4.0 no longer supports -language-version 1.9 (the last 1.x version). Clamp get_language_version() in versions.bzl to minimum 2.0 for extractor builds, and update the supported versions documentation.

Anders Fugmann	5732a99f9d	Kotlin 2.4.0: Fix extension receiver on property references In 2.4.0's unified parameters model, IrPropertyReference stores the bound extension receiver in the arguments list (indexed via the getter's extension receiver parameter). Our codeQlExtensionReceiver compat function only handled the case where symbol.owner is an IrFunction, returning null for IrPropertyReference (where symbol.owner is IrProperty). Fix: when the direct cast to IrFunction fails, look at the getter/setter function's parameters to find the extension receiver index.

Anders Fugmann	b89b6e432a	Kotlin 2.4.0: Use IrAnnotationImpl for annotation creation In 2.4.0, annotation lists are typed as List<IrAnnotation> and IrConstructorCallImpl does not extend IrAnnotation. Replace all IrConstructorCallImpl.fromSymbolOwner() calls that create annotations with a compat wrapper codeQlAnnotationFromSymbolOwner() that uses IrAnnotationImpl.fromSymbolOwner() in 2.4.0 (returning proper IrAnnotation instances) and IrConstructorCallImpl.fromSymbolOwner() in pre-2.4.0 versions.

Anders Fugmann	9723044342	Kotlin 2.4.0: Fix value argument indexing in compat layer In 2.4.0, IrMemberAccessExpression.arguments includes all parameters (dispatch receiver, extension receiver, and regular value args). The old getValueArgument/putValueArgument/valueArgumentsCount APIs indexed only value arguments. Fix the compat layer to apply the correct offset when translating between the old index-based API and the new unified arguments list.

Anders Fugmann	e21bc4da05	Kotlin 2.4.0: Fix plugin service file to be version-conditional The CompilerPluginRegistrar service file must only be included in the 2.4.0 jar. Older Kotlin versions (2.3.x and below) read this service file and try to cast the class to CompilerPluginRegistrar, but the older version extractor only implements ComponentRegistrar, causing a ClassCastException at runtime. For 2.4.0, the registrar implements both ComponentRegistrar (no-op, as extensionArea was removed) and CompilerPluginRegistrar (actual registration via ExtensionStorage).

Anders Fugmann	4a2f244ffa	Kotlin: Add 2.4.0 API compatibility layer and plugin registration - Add version-specific compatibility wrappers (v_2_4_0/IrCompat.kt) for removed APIs: valueParameters, extensionReceiverParameter, extensionReceiver, getValueArgument, putValueArgument, valueArgumentsCount, typeArgumentsCount, getTypeArgument, addAnnotations, setAnnotations, setDispatchReceiverParameter - Add pre-2.4.0 pass-through implementations (v_1_8_0/IrCompat.kt) - Migrate plugin registration from ComponentRegistrar to CompilerPluginRegistrar for 2.4.0 (v_2_4_0/Kotlin2ComponentRegistrar.kt) - Add META-INF service file for CompilerPluginRegistrar - Update all extractor source files to use codeQl* compat functions - All versions (1.8.0 through 2.4.0) build successfully Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>	2026-06-04 15:25:35 +02:00
Anders Fugmann	ed9e160e89	Kotlin: Add 2.4.0 compiler jars and register version Download kotlin-compiler-2.4.0.jar, kotlin-compiler-embeddable-2.4.0.jar, and kotlin-stdlib-2.4.0.jar from Maven Central. Add 2.4.0 to the VERSIONS list and update MODULE.bazel via bazel mod tidy. The extractor does not yet compile against 2.4.0 due to removed APIs (valueParameters, extensionReceiverParameter, getValueArgument, etc.). Version-specific compatibility shims are needed.
