- Removed platform-specific implementations.
- Now all semaphores are in-object, unless they need to be conditionally created.
- Similarly to `Mutex`, provided a dummy implementation for when `NO_THREADS` is defined.
- Similarly to `Mutex`, methods are made `const` for easy use in such contexts.
- Language bindings updated: `wait()` and `post()` are now `void`.
- Language bindings updated: `try_wait()` added.
Bonus:
- Rewritten the `#ifdef` in `mutex.h` to meet the code style.
Namely, move the drive dropdown to just the left of the path text box and don't include the former
in the latter.
This improves the UX on Windows.
In the UNIX case, since its concept of drives is (ab)used to provide shortcuts to useful paths, its
dropdown is kept at the original location.
Remove now unnecessary bindings of signal callbacks in the public API.
There might be some false positives that need rebinding if they were
meant to be public.
No regular expressions were harmed in the making of this commit.
(Nah, just kidding.)
Main:
- It's now implemented thanks to `<mutex>`. No more platform-specific implementations.
- `BinaryMutex` (non-recursive) is added, as an alternative for special cases.
- Doesn't need allocation/deallocation anymore. It can live in the stack and be part of other classes.
- Because of that, it's methods are now `const` and the inner mutex is `mutable` so it can be easily used in `const` contexts.
- A no-op implementation is provided if `NO_THREADS` is defined. No more need to add `#ifdef NO_THREADS` just for this.
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- Thread-safe utilities are therefore simpler now.
Misc.:
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
- Every case of lock, do-something, unlock is replaced by `MutexLock` (complex cases where it's not straightfoward are kept as as explicit lock and unlock).
- `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`.
- Renames PackedIntArray to PackedInt32Array.
- Renames PackedFloatArray to PackedFloat32Array.
- Adds PackedInt64Array and PackedFloat64Array.
- Renames Variant::REAL to Variant::FLOAT for consistency.
Packed arrays are for storing large amount of data and creating stuff like
meshes, buffers. textures, etc. Forcing them to be 64 is a huge waste of
memory. That said, many users requested the ability to have 64 bits packed
arrays for their games, so this is just an optional added type.
For Variant, the float datatype is always 64 bits, and exposed as `float`.
We still have `real_t` which is the datatype that can change from 32 to 64
bits depending on a compile flag (not entirely working right now, but that's
the idea). It affects math related datatypes and code only.
Neither Variant nor PackedArray make use of real_t, which is only intended
for math precision, so the term is removed from there to keep only float.
Was missed in #36393 because no `callable_mp()` calls were actually
compiled with `tools=no` in that PR.
Also work around GCC warning that also affects the
`call_with_variant_args_ret_helper` variant.
Arrays inside of Variant are unique and use reference counting.
When you assign a variant containing a packed array to another, or
when you call non const functions to arrays, this will work even
if the array is inside a dictionary, so they will from now pass
as reference.
The difference with regular variant arrays is that, once passed
to a function in the C++ API, they are no longer shared. This is
required for security and thread safety, as those arrays are
mainly used to pass data back and forth even between threads.
This attribute is now part of the standard we target so we no longer
need compiler-specific hacks.
Also enables -Wimplicit-fallthrough for Clang now that we can properly
support it. It's already on by default for GCC's -Wextra.
Fixes new warnings raised by Clang's -Wimplicit-fallthrough.
WARNING: Requires C++17 'guaranteed copy elision' to fix ambiguous
operator problems in Variant.
This was added for this commit (and future C++17 uses) in #36457.
This is a temporary hack until vnen and reduz can work on a proper fix.
The changes in 867d073b98 exposed a
GDScript issue, which apparently triggers an automatic unreferencing.
This hack only makes it possible to use the editor again, but GDScript
is still broken.
UDP sockets can be "connected" to filter packets from a specific source.
In case of a bound socket (e.g. server), a new socket can be created on
the same address/port that will receive all packets that are not
filtered by a more specific socket (e.g. the previously connect socket).
This way, a UDPServer can listen to new packets, and return a new
PacketPeerUDP when receiving one, knowing that is a "new client".
It was initially implemented in #5871 for Godot 3.0, but never really
completed or thoroughly tested for most platforms. It then stayed in
limbo and nobody seems really keen to finish it, so it's better to
remove it in 4.0, and re-add eventually (possibly with a different API)
if there's demand and an implementation confirmed working on all
platforms.
Closes#8770.
Due to the port to Vulkan and complete redesign of the rendering backend,
the `drivers/gles3` code is no longer usable in this state and is not
planned to be ported to the new architecture.
The GLES2 backend is kept (while still disabled and non-working) as it
will eventually be ported to serve as the low-end renderer for Godot 4.0.
Some GLES3 features might be selectively ported to the updated GLES2
backend if there's a need for them, and extensions we can use for that.
So long, OpenGL driver bugs!
It was added for 3.2 in #27485 to preserve backwards compatibility,
but we can now remove it.
It is still needed in MultiplayerAPI as it's the only way to control
it for the internal put_var calls.
- Now is sent the method ID rather the full function name.
- The passed IDs (Node and Method) are compressed so to use less possible space.
- The variant (INT and BOOL) is now encoded and compressed so to use much less data.
- Optimized RPCMode retrieval for GDScript functions.
- Added checksum to assert the methods are the same across peers.
This work has been kindly sponsored by IMVU.
- Replace unintended `%` with `&`
- `get_owned_list()`: make thread-safe and fix logic
- Apply same logic fix to the destructor
Previously, the determination of owned RIDs was wrong. For instance, it could skip owned items or include duplicates in the list.
Avoids the engine crashing at exit.
-Added VulkanContext
-Added an X11 implementation
-Added a rendering device abstraction
-added a Vulkan rendering device abstraction
-Engine does not work, only shows Godot logo (run it from bin/)
As pointed out by Faless, a do{ } while(0) wrapper around a continue or
break just ends the do{ } while(0) loop. The do{ } while(0) loop exists
to enable the macro to be used as a function which requires a semicolon.
The alternative approach is to use an if(1) { } else ((void)0) wrapper.
Since the macro already has an if(unlikely(m_cond)) { } this patch simply
adds the else ((void)0) to this if statement instead.
For consistency all the macros have been updated in the same way, and
trailing else warnings corrected. However, the wrappers around ERR_PRINT
and WARN_PRINT were removed, because they generated too many ambiguous
trailing else warnings. They are also single line macros so a wrapper is
not needed.
We already had `MODULE_*_ENABLED` defines but only in the modules
environment, and a few custom `*_ENABLED` defines in the main env
when we needed the information in core.
Now this is defined in a single header which can be included in the
files that need this information.
Pith bend message now has correct size (was 2 bytes instead of 3).
Recognized (but not implemented) 0xF? messages. SysEx messages will be reocognized as such, but their contents will be ignored.
Fixes#26637.
Fixes#19900.
The viewport_size returned by get_viewport_size was previously incorrect, being half the correct value. The function is renamed to get_viewport_half_extents, and now returns a Vector2.
Code which called this function has also been modified accordingly.
This PR also fixes shadow culling when using ortho cameras, because the correct input for CameraMatrix::set_orthogonal should be the full HEIGHT from get_viewport_half_extents, and not half the width.
It also fixes state.ubo_data.viewport_size in rasterizer_scene_gles3.cpp to be the width and the height of the viewport in pixels as stated in the documentation, rather than the current value which is half the viewport extents in worldspace, presumed to be a bug.
We used a lock signals in the signal_map while emitting, because it was
not allowed to disconnect them while being emitted.
We used that lock to check if we where deleting an object during signal
emission.
Now that we allow to disconnect signals while they are being emitted, if
an object first disconnects, then gets deleted we can't know that a
signal was being emitted during the destructor.
This commit adds a new `_emitting` boolean member to Object to be set
while emitting and checked in the destructor, while removing the old
signal lock which is now unused.
Used to allocate in stack (via alloca) which causes crashes when trying
to encode big variables.
The buffer grows as needed up to `encode_buffer_max_size` (which is
8MiB by default) and always in power of 2.
According to 22637beb2e (commitcomment-36651823)
and as confirmed by @reduz, this seems not to be necessary now that we
copy-on-write.
This triggered freeze scenarios in cases where a node would be deleted
while being used as a target in a signal emission.
Fixes#34650.
Fixes#34769.
Now those two errors go back to reporting:
```
ERROR: emit_signal: Condition ' !target ' is true. Continuing..:
At: core/object.cpp:1191.
```
Avoids crashes on debug mode. Instead it now breaks the execution and
show the error in-editor. Will still crash on release.
Also add a similar check to Marshalls to ensure the debugger doesn't
crash when trying to serialize the invalid instance.
Unify pack file version and magic to avoid hardcoded literals.
`version.py` now always includes `patch` even for the first release in
a new stable branch (e.g. 3.2). The public name stays without the patch
number, but `Engine.get_version_info()` already included `patch == 0`,
and we can remove some extra handling of undefined `VERSION_PATCH` this
way.

It will now give information about the originating object instance
and when locked, the target callback.
This should help debugging editor and game issues that are now being
reported due to adding signal locking in
22637beb2e.
Some cases were not handled properly for Polygon2D after making changes in common code to fix Line2D antialiasing. Added an option for drawing polygons to differentiate the two use cases.
Fixes#34568
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.
The calculation used to be wrong when exactly at a power of 2.
`nearest_shift` always return the "next" power of 2
`nearest_shift(4) == 3 # 2^3 = 8`.
On the other hand `next_power_of_2` returns the exact value if that
value is a power of 2 (i.e. `next_power_of_2(4) == 4`).
I.e. :
```
WARN_PRINT(itos(next_power_of_2(4)) + " " + itos(1 << nearest_shift(4)));
// WARNING: ... : 4 8
```
Is this by design?
