2019-04-09Style: Apply new changes from clang-format 8.0Rémi Verschelde
It seems to stay compatible with formatting done by clang-format 6.0 and 7.0, so contributors can keep using those versions for now (they will not undo those changes).
2019-01-30Fix many asan and ubsan reported issuesHein-Pieter van Braam
This allows most demos to run without any ubsan or asan errors. There are still some things in thirdpart/ and some things in AudioServer that needs a look but this fixes a lot of issues. This should help debug less obvious issues, hopefully. This fixes #25217 and fixes #25218

If it can be compared to a boolean, it can be evaluated as one in-place.
2018-09-12Make core/ includes absolute, remove subfolders from include pathRémi Verschelde
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.

2018-04-30Handle missing arg pointer in get_call_error_textGary Oberbrunner
I had a situation coming from godot-python where the caller of Variant::get_call_error_text() passed null for `p_argptrs`. In addition to fixing that in the caller, seems like good practice to defend against that situation in the callee to prevent a crash. So this patch just substitutes some semi-useful text for the source type name and keeps going so the user's actual error gets emitted.

2018-01-05Add missing copyright headers and fix formattingRémi Verschelde
Using `misc/scripts/fix_headers.py` on all Godot files. Some missing header guards were added, and the header inclusion order was fixed in the Bullet module.

2017-09-21Implement Linux-style likely()/unlikely() macrosHein-Pieter van Braam
This implement branch prediction macros likely() and unlikely() like in Linux. When using these macros please ensure that when you use them the condition in the branch really is very, very likely or unlikely. Think 90+% of the time. Primarily useful for error checking. (And I implement these macros for all our error checking macros now) See this article for more information: https://kernelnewbies.org/FAQ/LikelyUnlikely There are more places where these macros may make sense in renderer and physics engine. Placing them will come in another commit down the line.
2017-09-19Don't call Variant::reference() unnecessarilyHein-Pieter van Braam
operator= does not need to call reference() if the new value is of the same type as the old. This saves us zeroing the Variant, This speeds up reuse of a Variant in a loop by roughly 50%.
2017-09-14Construct Variants from Reference properly in GDNativeRuslan Mustakov
Previously godot_variant_new_object constructed Variant without accounting for the fact that the Object can be a Reference, so refcount was not increased and References were destructed prematurely. Also, Reference::init_ref did not propagate refcount increment to the script instance, which led to desync of refcount info on the script side and Godot side.

2017-08-24Convert Object::cast_to() to the static versionHein-Pieter van Braam
Currently we rely on some undefined behavior when Object->cast_to() gets called with a Null pointer. This used to work fine with GCC < 6 but newer versions of GCC remove all codepaths in which the this pointer is Null. However, the non-static cast_to() was supposed to be null safe. This patch makes cast_to() Null safe and removes the now redundant Null checks where they existed. It is explained in this article: https://www.viva64.com/en/b/0226/

2017-04-14Correct Variant::hash_compare()Hein-Pieter van Braam
There was a logic error in #7815 which made Variant.hash_compare() == Variant.hash_compare() always true. In an attempt to short-circuit the NaN check I made an (in hindsight) obvious error: 10 == 12 || is_nan(10) == is_nan(12) This will be true for all inputs, except for the NaN, not-NaN case. The macro has been updated to now generate: (10 == 12) || (is_nan(10) && is_nan(10)) so: (10 == 12) || (is_nan(10) && is_nan(12)) = false False or (False and False) is False (10 == 10) || (is_nan(10) && is_nan(10)) = true True or (False and False) is True (Nan == 10) || (is_nan(NaN) && is_nan(10)) = false False or (True and False) is False (Nan == Nan) || (is_nan(NaN) && is_nan(NaN)) = true False or (True and True) is True Which is correct for all cases. This bug was triggered because the hash function for floating point numbers can very easily generate collisions for the tested Vector3(). I've also added an extra hashing step to the float hash function to make this less likely to occur. This fixes #8081 and probably many more random weirdness.

2017-02-16Correct hash behavior for floating point numbersHein-Pieter van Braam
This fixes HashMap where a key or part of a key is a floating point number. To fix this the following has been done: * HashMap now takes an extra template argument Comparator. This class gets used to compare keys. The default Comperator now works correctly for common types and floating point numbets. * Variant implements ::hash_compare() now. This function implements nan-safe comparison for all types with components that contain floating point numbers. * Variant now has a VariantComparator which uses Variant::hash_compare() safely compare floating point components of variant's types. * The hash functions for floating point numbers will now normalize NaN values so that all floating point numbers that are NaN hash to the same value. C++ module writers that want to use HashMap internally in their modules can now also safeguard against this crash by defining their on Comperator class that safely compares their types. GDScript users, or writers of modules that don't use HashMap internally in their modules don't need to do anything. This fixes #7354 and fixes #6947.
2017-01-16Style: Fix statements ending with ';;'Rémi Verschelde
2017-01-16Style: Cleanups, added headers, renamed filesRémi Verschelde
Made sure files in core/ and tools/ have a proper Godot license header when written by us. Also renamed aabb.{cpp,h} and object_type_db.{cpp,h} to rect3.{cpp,h} and class_db.{cpp,h} respectively. Also added a proper header to core/io/base64.{c,h} after clarifying the licensing with the original author (public domain).

2017-01-01Welcome in 2017, dear changelog reader!Rémi Verschelde
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games!
