0ms hotload fast path poc when only method bodies change using MonoMod Biggest flaw of this is detecting the changes, Ziks has some good ideas with comparing the AST https://files.facepunch.com/matt/1b2611b1/sbox-dev_My23jH4uYG.mp4 Print individual changes during compile, show node paths WIP check if all changes are in method bodies Add attributes to package assemblies describing changed methods * SupportsILHotloadAttribute is added if only method bodies change * MethodBodyChangeAttribute is added for each changed method Yet to properly support nested declaring types and methods with overloads. ILHotload looks for SupportsILHotload and MethodBodyChange attributes Fixed methods with identical IL not being replaced by ILHotload ILHotload should never run with a debugger attached Clean up dead code Detour using a generated dynamic method copy from the replacing method Documentation for Compiler.SyntaxTree.cs Added CompilerSettings.SourcePathFilter predicate Boilerplate for writing ILHotload tests Fixed how file changes are emulated in FastPathTest A bit more flexibility in fast path test case code preprocessing Added failing fast path hotload test for changing method signatures ILHotload: changes must be specifically within a BlockSyntax of a method Added Compiler.UpdateParseOptions() for tests to use Don't use ILHotload if a preprocessor define changed Incremental syntax tree parsing Throw when trying to debug an ILHotload swap during a test Basic incremental compilation Make generated code more deterministic, nicer for incremental compile Keep track of which assembly types are actually loaded from Re-use compiler options where possible Changed fast hotload log to a trace Make OnlyMethodBodiesChanged multithreaded, fixed multiple changes in one file Failing test for property body changes Cleanup ILHotload tests, failing test for overloaded method Refactor AST processing for ILHotload Moved to Sandbox.Generator, and now tags changed methods with an attribute rather than referencing them from assembly-level attributes Fixes after refactor, a bit ugly at the moment Support fast hotload for property accessors NoticeWidget shows ms if duration < 1s Call UISystem.OnHotload after an ILHotload ILHotload test for nested blocks Fixed ILHotload change detection for nested blocks Added hotload_fast engine convar to enable / disable IL hotload
