We prefer to prevent using chained assignment (`T a = b = c = T();`) as this
can lead to confusing code and subtle bugs.
According to https://en.wikipedia.org/wiki/Assignment_operator_(C%2B%2B), C++
allows any arbitrary return type, so this is standard compliant.
This could be re-assessed if/when we have an actual need for a behavior more
akin to that of the C++ STL, for now this PR simply changes a handful of
cases which were inconsistent with the rest of the codebase (`void` return
type was already the most common case prior to this commit).
Ensure better compatibility when emcc which may run some tools from
different paths (e.g. closure compiler).
This fixes externs include issues with modern emcc using the closure
compiler.
This actually makes sense(?), when running inside an iframe the active
element might be our canvas, while the iframe itself is not active in
the parent window. Since we consume the event, the iframe does not get
focused in Firefox (but does in Chromium-based browsers), so we must
always call focus to handle such occasions.
Note, the editor build requires the mbedtls module to be manually
enabled, as it is currently needed as a ResourceUID dependency.
This will need to be addressed in a separate PR.
In some conditions the events might be generated even when the `gamepad`
object is not accessible due to Security Context requirements.
This commit adds a check to avoid firing the handler in those cases.
Building `target=release` and `target=release_debug` builds with MinGW-GCC
errors when linking with LTO.
Since it's only needed for `target=debug` builds anyway (bigger objects), which
we don't build with LTO, this works around the issue.
Equivalent `-Wa,-mbig-obj` for GCC/Clang.
This started being needed to compile harfbuzz in `target=debug` with MinGW/GCC,
but there doesn't seem to be any drawback to enabling `/bigobj` (aside from
losing support for pre-VS 2005 linkers, which we don't support).
A window can be closed on the server side while processing results from
_NET_CLIENT_LIST, which causes BadWindow fatal errors by default in
XGetWindowProperty.
The only way to safely catch this case is to set an error handler to
ignore BadWindow errors while these commands are processed.
Some platforms (*cough* web *cough*) have hard limits on the number of
threads that can be spawned.
Currently, ThreadPoolWork (mostly used in rendering/physics servers)
will spawn as many threads as CPUs available causing exception on
machines with high CPU count.
This commit adds a new overridable method to OS that returns the default
thread pool size (still the CPU count by default), and overrides it for
the JavaScript platform so it always allocate only one thread.
We can likely improve the whole ThreadPoolWork in the future to always
allocate X amount of threads, and assign jobs to them on the fly, but
that will require some more architectural changes.
Only Vulkan is fully implemented for now, so OpenGL isn't available
in the project manager yet.
This also makes the rendering driver checks use lowercase names
everywhere for consistency.
- Rename OpenGL to GLES3 in the source code per community feedback.
- The renderer is still exposed as "OpenGL 3" to the user.
- Hide renderer selection dropdown until OpenGL support is more mature.
- The renderer can still be changed in the Project Settings or using
the `--rendering-driver opengl` command line argument.
- Remove commented out exporter code.
- Remove some OpenGL/DisplayServer-related debugging prints.
First implementation with Linux display manager.
- Add single-threaded mode for EditorResourcePreview (needed for OpenGL).

Helps with fixing issues with scrolling popups not respecting screen
decorations on the display server side.
Reproduction steps for a simple use case:
- Start the editor project list
- Open the language selection popup
Support for multi-screen:
Handling decorations is supported in different ways depending on the
information the window manager provides:
- _GTK_WORKAREAS is used when available from the WM to get accurate rect
for the different screens directly (available on Gnome).
- Alternatively, strut information is used to calculate available space
for a given desktop manually (XFCE, KDE).
- As last resort _NET_WORKAREA is used. It provides one full rect for all
screens, which doesn't handle decorations on the secondary screen in all
cases.
This method used to check which screen contains the top-left corner of
the window (and default to the first screen in case none is found),
which is not accurate in some cases.
Now the area of overlap with each screen is calculated, so we can get
the best candidate based on the window's position.
This makes window_get_current_screen consistent with Windows platform,
and fixes an issue where popups appear on the main screen when the main
window is slightly moved outside of the desktop on the top or left.
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
The new system based on a thread gathering events from the X11 server
was causing delays in some scenarios where some events have just been
missed at the time of processing and we're waiting for a whole frame to
check them again.
Solved by flushing again and checking for pending events at the
beginning of the process loop, in addition to events already gathered
on the event thread.
Previously, files added via `add_ios_project_static_libs` where
being added as embedded frameworks. This commit fixes that.
Static frameworks/libs should never be embedded into IPAs.
We've had many issues with WebM support and specifically the libvpx library
over the years, mostly due to its poor integration in Godot's buildsystem,
but without anyone really interested in improving this state.
With the new GDExtensions in Godot 4.0, we intend to move video decoding to
first-party extensions, and this would likely be done using something like
libvlc to expose more codecs.
Removing the `webm` module means we can remove libsimplewebm, libvpx and
opus, which we were only used for that purpose. Both libvpx and opus were
fairly complex pieces of the buildsystem, so this is a nice cleanup.
This also removes the compile-time dependency on `yasm`.
Fixes lots of compilation or non-working WebM issues which will be linked
in the PR.
This will allow adding developer checks which will be fully compiled out in
user builds, unlike `DEBUG_ENABLED` which is included in debug tempates and
the editor builds.
This define is not used yet, but we'll soon add code that uses it, and change
some existing `DEBUG_ENABLED` checks to be performed only in dev builds.
Related to godotengine/godot-proposals#3371.
All Android devices that support Vulkan support 64-bit ARM.
This also removes NEON opt-out code for ARMv7 as pretty much all
ARMv7 devices also support NEON.
On OpenBSD the compiler complains that calling basename(3) would lose
const qualifier. basename(3) is defined as
char *basename(char *);
and can, accorgindly to the POSIX.1, modify the passed string.
This uses the .get_file() method. The check is necessary because
file_name could be a directory, in which case .get_file() would return
an empty string. The .get_base_dir().get_file() idiom is already used.
The usage of get_file() and the check were suggested by theraot, thanks!
It used an old vendored version of acorn.js which seems to choke on this
trailing comma. This is not a problem for more recent Emscripten versions.
We disable the `comma-dangle` check in ESLint to prevent this issue.
`#pragma once` was used in a few files, yet we settled on using
traditional include guards instead.
The PooledList template comment was also moved to allow editors
such as Visual Studio Code to display the comment when hovering
PooledList.
`app.h` was renamed to `app_uwp.h` to be less generic for the
include guard.
Performances are not great in general, bad on Firefox, on Chrome, well,
it could be an improvement. Leave it as a fallback for now, but can be
forced via project settings if desired (or custom JavaScript logic via
the "args" option).
I'm actually surprised this works, it involves so many allocations, but
there's no way around it when SharedArrayBuffer is not available :(.
This only adds support for a subset of Play Asset Delivery: this causes a single install-time asset pack to always be present, but doesn't add support for dynamically downloaded asset packs.
Browsers doesn't really like forcing the mix rate, e.g. Firefox does not
allow input (microphone) if the mix rate is not the default one, Chrom*
will exhibit worse performances, etc.
This provides better security at the cost of having misleading
binary icons on some file managers.
Now that recent Linux distributions no longer allow executing
binaries by double-clicking them in a file manager (even if the
binary is set to be executable), the usability cost of PIE is lowered.
You have to use a terminal or install a `.desktop` file nowadays.
After input buffering was reworked, input accumulation is now handled
outside of OS, and the JavaScript plaform never implemented that.
Additionally, the JavaScript platform is quite obnoxious about calling
specific APIs outside specific user triggered events.
This commit adds event flushing during the main iteration, and forces it
during keydown/keyup/mousedown/mouseup/touchstart/touchend/touchcanel
events (effectively only accumulating only "move" events).
Doesn't change the default behavior, but allows plugins to add their
view behind the main view, which gives more control over what happens
with inputs and can be useful along with transparent rendering.
- Don't display messages when enabling PulseAudio/ALSA/D-Bus/udev
as these become noisy in incremental builds.
- Improve warning and error messages to be more descriptive
and consistent.
This is done by providing API access to app specific directories which don't have any limitations and allows us to bump the target sdk version to 30.
In addition, we're also bumping the min sdk version to 19 as version 18 is no longer supported by Google Play Services and only account of 0.3% of Android devices.
This makes for easier organization since downloading a project
several times (or several different projects) will result in more
meaningful file names.
This prevents the D-pad up arrow from being registered as pressed
when it isn't, and pressing any direction from activating the next
arrow clockwise of it.

Key, touch and joystick events will be passed directly from the UI thread to Godot, so they can benefit from agile input flushing.
As another consequence of this new way of passing events, less Java object are created at runtime (`Runnable`), which is good since the garbage collector needs to run less.
`AndroidInputHandler` is introduced to have a smaller cross-thread surface. `main_loop_request_go_back()` is removed in favor just inline calling `send_window_event()` at the most caller's convenience (i.e., leveraging the new `p_deferred`` parameter as appropriate).
Lastly, `get_mouse_position()` and `get_mouse_button_state()` now just call through `Input` to avoid the need of sync of mouse data tracked on the UI thread.
Input buffering is implicitly used by event accumulation, but this commit makes it more generic so it can be enabled for other uses.
For desktop OSs it's currently not feasible given main and UI threads are the same).
- API has been simplified: all events now go through `parse_input_event()`. Whether they are accumulated or not depends on the `use_accumulated_input` flag.
- Event accumulation is now thread-safe (it was not needed so far, but it prepares the ground for the following changes).
- Touch drag events now support accumulation.
This was caused by the fact that a new instance of Godot was created at resume while a previous instance already existed.
The previous instance would then go through its cleanup lifecycle, and would thus attempt to close the entire app, leading to the system to restart the app, thus starting the cycle anew.
The fix involves reusing the previous instance of Godot if one is available instead of creating a new one, as well as giving control to the host activity for how the process should be terminated.
