From e59ac40712aa656e94072f0bdd60147c49b003aa Mon Sep 17 00:00:00 2001 From: Ignacio Etcheverry Date: Thu, 11 Jul 2019 14:01:25 +0200 Subject: [PATCH] Mono: Better handling of missing/outdated API assemblies Remove the old API assembly invalidation system. It's pretty simple since now the editor has a hard dependency on the API assemblies and SCons takes care of prebuilding them. If we fail to load a project's API assembly because it was either missing or outdated, we just copy the prebuilt assemblies to the project and try again. We also do this when creating the solution and before building, just in case the user removed them from the disk after they were loaded. This way the API assemblies will be always loaded successfully. If they are not, it's a bug. Also fixed: - EditorDef was behaving like GlobalDef in GodotTools. - NullReferenceException because we can't serialize System.WeakReference yet. Use Godot.WeakRef in the mean time. --- modules/mono/csharp_script.cpp | 21 +- .../GodotTools/GodotTools/GodotSharpBuilds.cs | 126 +---- .../GodotTools/GodotTools/GodotSharpEditor.cs | 87 +-- .../GodotTools/Internals/Internal.cs | 23 +- modules/mono/editor/editor_internal_calls.cpp | 24 +- modules/mono/mono_gd/gd_mono.cpp | 518 ++++++++---------- modules/mono/mono_gd/gd_mono.h | 15 +- 7 files changed, 262 insertions(+), 552 deletions(-) diff --git a/modules/mono/csharp_script.cpp b/modules/mono/csharp_script.cpp index 1add697997c..078a490b22e 100644 --- a/modules/mono/csharp_script.cpp +++ b/modules/mono/csharp_script.cpp @@ -114,15 +114,20 @@ void CSharpLanguage::init() { gdmono = memnew(GDMono); gdmono->initialize(); -#ifndef MONO_GLUE_ENABLED - WARN_PRINT("This binary is built with `mono_glue=no` and cannot be used for scripting"); -#endif - #if defined(TOOLS_ENABLED) && defined(DEBUG_METHODS_ENABLED) + // Generate bindings here, before loading assemblies. `initialize_load_assemblies` aborts + // the applications if the api assemblies or the main tools assembly is missing, but this + // is not a problem for BindingsGenerator as it only needs the tools project editor assembly.
