ClassLoading 0.6.0

Add loop and if-statements detection to decompilation, also handle basic try-catch and synchronized blocks.

Added

• StringBuilderIndent provides the same API as StringBuilder (unfortunately we can't extend StringBuilder because it is final) and implements Indent so that this class can be used to easily build source code strings
• src/twg2/jbcm/toSource/structures with state handlers for inserting more complex structures such as loops and try-catch statements into source code during opcode iteration

Changed

• twg2.jbcm.classFormat.attributes.Code toClassString() renamed toClassCodeString()
• CpIndexChanger is now stateful and contains the old and new index and uses a proper visitor pattern to handle changing indexes
• Indent changed from a class to an interface with a public static Impl subclass
• IterateCode renamed CodeIterator
• RuntimeReloadMain refactored, more complex threaded loading and invocation of methods from updated class files, some code moved to new classes twg2.jbcm.runtime.ClassLoaders and FileUtility
• twg2.jbcm.runtimeLoading package renamed twg2.jbcm.runtime
• CodeFlow contains algorithms for detecting loops and if-statements in byte code
• DataCountingInputStream added and used in ClassFile when parsing a class to improve debug and error message with exact byte index locations
• Several new unit/integration tests added, CompileTest renamed CompileJava
• Fixed compiling code during runtime to support class names with arbitrary package paths, required extensive changes to CompileSource
• JumpConditionInfo rewritten to support representing loop and nested if-statement conditions
• TypeUtility.classNameFieldDescriptor() renamed toBinaryClassName()

ClassLoading 0.5.1

Fix switch statements to decompile much more accurately based on code flow analysis. Start work on if statements.

Added

• new Indent class to handle SourceWriter indentation
• Switch to handle switch code flow initialization and info

Changed

• Add code flow analysis initialization and info to JumpConditionInfo
• Assume that a forward goto right before a condition is an else statement

ClassLoading 0.5.0

Decompilation to source code in-progress and first round trip compile/decompile unit tests

Added

• A new twg2.jbcm.ir package with helper classes for tracking state and data related to decompilation
• CodeOffsetGetter interface implemented by ChangeCpIndex
• CodeFlow for helping analyze potential code flow paths through a method
• Unit tests with tests which perform compilation of source code and check decompilation back to intermediate view

Changed

• CodeToSource is in-progress, simple code can be converted, loops, switch statements, and interface/dynamic method calls are still TODO
• Split IoUtility into new CodeUtility class and moved static no-op CpIndexChanger and CodeOffsetChanger into their respective interfaces
• Renamed ByteCodeConsumer -> BytcodeConsumer
• Moved MethodStack to new twg2.jbcm.ir package
• Lots of new functionality in Opcodes to support to source decompilation
• Extensive CompileSource changes/improvements to support simple use cases like compiling in-memory (although a physical temp file still gets written under the hood)
• Moved LookupswitchOffsetModifier and TableswitchOffsetModifier out of IoUtility and into their own classes

Removed

• CpIndexChanger.shiftIndex() interface method since it was unused and CodeOffsetChanger is equivalent
• Unused classes: Offset, OffsetOpcode, Opcode, OpcodeObject

ClassLoading 0.3.0

Changed

• Upgrade to Java 9
• Java 9 ClassFile format support:
  • New Attributes: Module, ModuleMainClass, ModulePackages
  • New constant pool types: CONSTANT_Module, CONSTANT_Package
• Renamed/changed the public static final int CONSTANT_*_info field to public static final byte TAG and removed the instanced tag field from all constantPool classes
• Renamed Target_Info_Type -> Target_Info_Union
• Consolidated twg2.jbcm.classFormat.attributes, nested classes that are only used by one class inside the class
• Added/fixed several attributes' toString() methods
• Cleaned up some attributes field documentation
• Renamed UnitTest -> UsageCliMain and added support for printing dependencies and loading multiple classes, printing multiple classes, and clearing loaded classes

ClassLoading 0.2.1

Changed

• Forgot to update jar file

ClassLoading 0.2.0

Changed

• Cleaned up unnecessary twg2.jbcm.opcode package classes
• Renamed twg2.jbcm.modify.IndexChange -> IndexChanger
• Renamed twg2.jbcm.modify.OpcodeChangeCpIndex -> CpIndexChanger
• Renamed twg2.jbcm.modify.OpcodeChangeOffset -> CodeOffsetChanger

ClassLoading 0.1.0

Added

• Initial versioning of existing code, including classfile loading/parsing, dynamic classfile modification, and runtime class loading.

ClassLoading 0.4.0

Added

• ClassFileToSource and CodeToSource work-in-progress to convert class file back into Java source code
• CONSTANT_CP_Info.toShortString() added interface method and to implementations

Changed

• Clean up Settings mega-utility class. Move methods into ConstantPoolExtensions, ClassFile, and ClassFileAttributes
• Cleaned up Opcodes

Removed

• Unused ConstantPoolIndexArray and ConstantPoolTag annotations
