2018-09-27Fix warnings about unhandled enum value in switch [-Wswitch]Rémi Verschelde
Fixes GCC 5 warnings of the form: core/io/http_client.cpp:288:9: warning: enumeration value 'STATUS_SSL_HANDSHAKE_ERROR' not handled in switch [-Wswitch] core/io/marshalls.cpp:806:9: warning: enumeration value 'AABB' not handled in switch [-Wswitch] Those can be trivial cases where adding a default fallback is the solution, or more complex issues/hidden bugs where missed values are actually meant to be handled.

2018-09-19Fixed an access after free in ShaderLanguage::_reduce_expression.Ibrahn Sahir
Passing an element reference of a vector to a push_back call to that same vector can cause an access after free. This is because push_back will resize the vector, reallocating if necessary, leaving the reference referring to the freed memory. Removed an instance of this usage here.

This allows more consistency in the manner we include core headers, where previously there would be a mix of absolute, relative and include path-dependent includes.

2018-07-26Reduce unnecessary COW on Vector by make writing explicitHein-Pieter van Braam
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<int> 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.

2018-04-22Change ".." punctuation for "..." in editor strings (#16507)Hugo Locurcio
2018-04-21Fixes logically dead code (Coverity)Crazy-P
Fixes reported logically dead codes by Coverity * image.cpp: Doesn't really need any modification. But to remove the bug report then we have to move the MAX call away from the for loop statement. * rasterizer_gles3.cpp: Removes unnecessary elif condition since it is checked earlier in the function * collada.cpp: If stamement never reached due to macro ERR_CONTINUE does the same. * navigation_mesh.cpp: Variables should always be null - however, also checked for the very same condition in their function call. Leaving this for review (whether the function call is necessary or not) * path_editor_plugin.cpp: If cancel is true, then it should restore the edited value to the original provided. http://docs.godotengine.org/en/3.0/classes/class_editorspatialgizmo.html#class-editorspatialgizmo-commit-handle * spatial_editor_gizmos.cpp: the very condition of i >= 3 is predetermined in the if case right before it. Thus case 1 is always '1' and case 2 is always '-1' * grid_map_editor.cpp: Same as above in spatial_editor_gizmos.cpp * voxel_light_baker.cpp: Same as above in spatial_editor_gizmos.cpp * visual_server.cpp: Same as above in spatial_editor_gizmos.cpp * visual_script_expression.cpp: char '-' is already true in the switch case mechanism. Thus it can never reach to default case. * particles.cpp: Case 'PARAM_MAX' is unreachable due to index checking right before the switch execution. * shader_language.cpp: Invalid index is handled in switch default case. `type < TYPE_FLOAT && type > TYPE_VEC4` -> `(type < TYPE_FLOAT || type > TYPE_VEC4`) Fixes the "always false problem" in TODO comment.

2018-01-22Handle single-argument constructors in shaders.Benjamin
Expand these (fill vectors, fill matrix diagonals) in _reduce_expression() so they're handled properly even as uniform default values (where they previously caused a crash).
