From 0e29f7974b59e4440cf02e1388fb9d8ab2b5c5fd Mon Sep 17 00:00:00 2001 From: Hein-Pieter van Braam Date: Wed, 25 Jul 2018 03:11:03 +0200 Subject: Reduce unnecessary COW on Vector by make writing explicit This commit makes operator[] on Vector const and adds a write proxy to it. From now on writes to Vectors need to happen through the .write proxy. So for instance: Vector vec; vec.push_back(10); std::cout << vec[0] << std::endl; vec.write[0] = 20; Failing to use the .write proxy will cause a compilation error. In addition COWable datatypes can now embed a CowData pointer to their data. This means that String, CharString, and VMap no longer use or derive from Vector. _ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug builds. This is a lot faster for Vector in the editor and while running tests. The reason why this difference used to exist is because force-inlined methods used to give a bad debugging experience. After extensive testing with modern compilers this is no longer the case. --- core/project_settings.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'core/project_settings.cpp') diff --git a/core/project_settings.cpp b/core/project_settings.cpp index 60e8933751..c24b7d5a87 100644 --- a/core/project_settings.cpp +++ b/core/project_settings.cpp @@ -627,7 +627,7 @@ Error ProjectSettings::_save_settings_binary(const String &p_file, const Map buff; buff.resize(len); - err = encode_variant(p_custom_features, &buff[0], len); + err = encode_variant(p_custom_features, buff.ptrw(), len); if (err != OK) { memdelete(file); ERR_FAIL_V(err); @@ -664,7 +664,7 @@ Error ProjectSettings::_save_settings_binary(const String &p_file, const Map buff; buff.resize(len); - err = encode_variant(value, &buff[0], len); + err = encode_variant(value, buff.ptrw(), len); if (err != OK) memdelete(file); ERR_FAIL_COND_V(err != OK, ERR_INVALID_DATA); -- cgit v1.2.3
