This moves the instance id member from Variant to the ObjectRC so that Variant is still the same size as before the fix (and also regardless if debug or release build).
This commit addresses multiple issues with `Variant`s that point to an `Object`
which is later released, when it's tried to be accessed again.
Formerly, **while running on the debugger the system would check if the instance id was
still valid** to print warnings or return special values. Some cases weren't being
warned about whatsoever.
Also, a newly allocated `Object` could happen to be allocated at the same memory
address of an old one, making cases of use hard to find and having **`Variant`s pointing
to the old one magically reassigned to the new**.
This commit makes the engine realize all these situations **under debugging**
so you can detect and fix them. Running without a debugger attached will still
behave as it always did.
Also the warning messages have been extended and made clearer.
All that said, in the name of performance there's still one possible case of undefined
behavior: in multithreaded scripts there would be a race condition between a thread freeing
an `Object` and another one trying to operate on it. The latter may not realize the
`Object` has been freed soon enough. But that's a case of bad scripting that was never
supported anyway.
Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
Similarly to `Vector2` and `Rect2` transforms in 2D and Vector3, Plane,
and AABB in 3D. PoolVector2Array and PoolVector3Array were the only
missing Variant types in both Transform2D and Transform respectively.
Condensed some if and ERR statements. Added dots to end of error messages
Couldn't figure out EXPLAINC. These files gave me trouble: core/error_macros.h, core/io/file_access_buffered_fa.h (where is it?),
core/os/memory.cpp,
drivers/png/png_driver_common.cpp,
drivers/xaudio2/audio_driver_xaudio2.cpp (where is it?)
These silently fail, so they should be removed. I accidentally added most of these last year, trying to make everything else consistent with Quat, sorry!
Also, a few tiny nitpicking changes are included, like whitespace and misspellings.
For clarity, assign-to-release idiom for PoolVector::Read/Write
replaced with a function call.
Existing uses replaced (or removed if already handled by scope)
Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.
Improved documentation of rsplit Method for String class.
Removed "divisor" (i will also change variants_call.cpp) and added "delimiter" in its place. Also moved the example at the bottom of the description.
The Quat(Vector3) constructor, to initialise a Quat by a euler angle,
was impossible because Variant::construct would only check for
constructors with greater than 1 arguments. I changed it to greater than
or equal to 1 and moved it to the bottom of the priority list so it did
not overshadow the other checks that checked for arguments equal to 1
for simple copy constructors.
The return_type is used by the GDScript parser (and possibly other
scripting languages), so it MUST be initialized at least.
It could be initialized to Variant::NIL in release, but I see no reason
for not setting the actual value.
See similar issue in 95dfa5b .
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.
They were introduced in #14704 but need more discussion IMO,
they don't strike me as core features that would have to be
registered in Variant directly.
Moreover, they currently break the documentation XML as string
constants end up encoded as e.g. `value=""..""`.
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.
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.
Remove negative limit, leave only positive and make it reflect behaviour like in Python
Also limit renamed to maxsplit to match Python one.
Also docs updated.
