This fixes UBSAN errors reported by running our testsuite, importing the
TPS demo, and running the TPS demo. I have tried, wherever possible, to
fix issues related to reported issues but not directly reported by UBSAN
because thse code paths just happened to not have been exercised in
these cases.
These fixes apply only to errors reported, and caused by, core/
The following things have been changed:
* Make sure there are no implicit sign changing casts in core.
* Explicitly type enums that are part of a public API such that users of
the API cannot pass in wrongly-sized values leading to potential stack
corruption.
* Ensure that memcpy is never called with invalid or null pointers as
this is undefined behavior, and when the engine is built with
optimizations turned on leads to memory corruption and hard to debug
crashes.
* Replace enum values only used as static values with constexpr static
const values instead. This has no runtime overhead. This makes it so
that the size of the enums is explicit.
* Make sure that nan and inf is handled consistently in String.
* Implement a _to_int template to ensure that all of the paths use the
same algorhithm, and correct the negative integer case.
* Changed the way the json serializer precision work, and added tests to
verify the new behavior. The behavior doesn't quite match master in
particulary for negative doubles as the original code tried to cast -inf
to an int. This then led to negative doubles losing all but one of
their decimal points when serializing. Behavior in GDScript remains
unchanged.
Windows 11's major version number is actually 10.x.x, which can be confusing
if you don't know about this quirk. `OS.get_version_alias()` avoids this
by displaying the "branding" version number and the build number as a suffix,
so that individual updates can still be distinguished from each other.
On macOS, `OS.get_version_alias()` returns the version number prepended
with the version name (e.g. Sequoia for macOS 15).
On other operating systems, this returns the same value as `OS.get_version()`.
`core/os/os.h` doesn't use `core/io/image.h`. It just brings
transitive dependencies. Lots of dependencies because `core/os/os.h`
is transitively included in almost every file of godot
Also added `core/io/image.h` into files^1 where `Ref<Image>` and `core/os/os.h`
were used to prevent obscure errors involving `Ref<Image>`
^1 except those which include `core/io/image_loader.h` or `core/io/image.h` by
corresponding .h file with the same name

Features:
- Debug-only tracking of objects by type. See
get_driver_allocs_by_object_type et al.
- Debug-only Breadcrumb info for debugging GPU crashes and device lost
- Performance report per frame from get_perf_report
- Some VMA calls had to be modified in order to insert the necessary
memory callbacks
Functionality marked as "debug-only" is only available in debug or dev
builds.
Misc fixes:
- Early break optimization in RenderingDevice::uniform_set_create
============================
The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
Fixes#73374
As of godot 4 On windows/osx the game window will be frozen and will not
be updated.
In the debugger loop it calls
OS::get_singleton()->process_and_drop_events();
which allows windows/osx to handle system events. If the window doesn't
handle these events then both systems will judge the window to be 'not
responding' (osx beachball cursor)
When the event processing code was migrated from OS to DisplayServer the
process_and_drop_events() logic was moved to DisplayServer, but the call
inside the remote debugger pause loop was not updated to call the
DisplayServer version, there are currently no implementations of
OS::process_and_drop_events() so i removed it and switched to the new
DisplayServer::force_process_and_drop_events() method.
Adds 3D fixed timestep interpolation to the rendering server.
This does not yet include support for multimeshes or particles.

Folder names ending with one or more `.` characters are not allowed
on Windows, so this would break writing logs, shader cache and other
project-specific files. Trailing periods are now stripped in this case.
On non-Windows platforms, this change still applies in the interest
of portability.
Aims for more consistent MIDI support across Windows, MacOS, Linux and
to provide a base for adding MIDI drivers for other platforms.
Reworks the MIDIDriverALSAMidi MIDI parsing implementation as a platform
independent version in MIDIDriver::Parser.
Uses MIDIDriver::Parser to provide running status support in MacOS
MIDIDriverCoreMidi.
Collects connected input names at open, ensuring devices indices reported
in events match names in array returned from get_connected_inputs.
Fixes#77035.
Fixes#79811.
