SDL_CreateWindow() may call GetWindowDisplayIndex() to compute the position
of a new window that the caller has requested to be placed on a certain
display. Since we haven't fully constructed the window yet, our driverdata
will be nil and we will fail to get the NSScreen (which is fine). However,
we need to return an error (not 0, which is a valid display index) for
SDL_GetWindowDisplayIndex() to know to figure out the display index itself.
Fixes positioning new windows on secondary displays when using
SDL_WINDOWPOS_CENTERED_DISPLAY() and SDL_WINDOWPOS_UNDEFINED_DISPLAY().
The video core assumes that window->w/h will be updated before returning
from SetWindowFullscreen(). This is needed to generate a resize event
with the correct window size when exiting fullscreen.
The roundtrip allows us to receive the configure callback that informs
us of the new window size before returning.
Fixes#6043
This is necessary for consistent position reports with absolute mice
and improves application performance with relative mice by cutting the
number of reported mouse motion events roughly in half.
- CMD_CHARGE_STATE was checking the seqnum instead of the payload
- Off-by-one error in size validation for command payload
- Unused payload space was left uninitialized in output report
The HIDAPI joystick driver doesn't properly reset the change counter
it uses to track if re-enumeration is needed when the joystick
subsystem is quit and then reinitialized.
The first SDL_Init(SDL_INIT_JOYSTICK) will result in the expected
HIDAPI joysticks appearing, but subsequent calls will result in no
joysticks being enumerated until another HIDAPI joystick is added
or removed from the system.
libGL.so may register callbacks that can be invoked upon XCloseDisplay().
If XCloseDisplay() is called after libGL.so is unloaded, the callback pointer
will point at freed memory and invoking it will crash.
The texture framebuffer check optimized out in f37e4a9 was causing libGL.so to
never be unloaded as a side-effect. Skipping it exposed this bug by allowing
libGL.so to actually unload.
We were returning the report size from HIDAPI_DriverPS5_RumbleJoystick() rather
than 0 upon success, causing SDL_JoystickRumble() (and callers) to think that
rumbling failed.
This didn't cause major problems until 1868c5b, when it started preventing
rumble state from being persisted in the joystick core, even though it was
successfully sent to the hardware.
This led to all sorts of strangeness, including broken rumble duration and
attempts to stop rumble being discarded.
The name that the Raw Input joystick driver pulls from the HID stack comes
from USB string descriptors contained on the device. For official wireless
receivers, this always contains "Xbox 360 Wireless Receiver for Windows"
which matches the friendly name that WGI provides.
3rd party Xbox 360 wireless receivers may have different strings in their
USB string descriptors (one uses "XBOX 360 For Windows" instead). This
fails to match WGI's name and causes Raw Input and WGI to both report the
same gamepad.
Since wireless Xbox 360 controllers seem to have a consistent VID/PID
regardless of the adapter enumerating them, we can also match on that to
catch these.
The duplicate case reported to me was:
Controller (XBOX 360 For Windows) - 030000005e040000a102000000007200
Xbox 360 Wireless Receiver for Windows - 030000005e0400000000000000007701
If we get a SDL_SetWindowSize() call right after SDL_SetWindowFullscreen() but
before we've gotten a new configure event from the compositor, the attempt to
set our window size will silently fail (when libdecor is enabled).
Fix this by remembering that we need to commit a new size, so we can do that
in decoration_frame_configure().
We don't want to catch explicit SDL_PumpEvents() calls by the application with
our polling check to avoid stale data. If the call to SDL_PumpEvents() produced
no events, there will be a sentinel sitting in the queue that will cause
SDL_PollEvent() to immediately return 0 next time it is called.
Our SDL_WaitEventTimeout() implementation avoids this issue by always popping
an event after calling SDL_PumpEvents(). This will remove the new sentinel if
we didn't get any new events.
WGI calls SDL_DINPUT_JoystickPresent() so we need to be sure DInput remains
initialized for the lifetime of the WGI driver to avoid a crash or duplicated
joysticks between DInput and WGI.
Rounding the scroll deltas from trackpads causes jerky scrolling behavior
by artificially amplifying the effects of very small scroll movements.
We should only round events from devices with discrete scroll wheels,
because we know the smallest unit of movement there is a single tick.
When our keyboard grab hook is installed, GetKeyState() will return 0 for the
GUI keys even when they are pressed. This leads to spurious key up events when
holding down the GUI keys and the inability to use any key combos involving
those modifier keys.
Touching HID devices with keyboard usages will trigger a keyboard capture
permission prompt on macOS 11+. See #4887
Like the IOKit joystick backend, we accept HID devices that have joystick,
gamepad, or multi-axis controller usages. We also allow the Valve VID for
the Steam Controller, just like the Windows HIDAPI implementation does.
We can also ditch the lock in RAWINPUT_JoystickQuit() now that the joystick
subsystem quits drivers in reverse order. There's no chance of a racing call
to RAWINPUT_WindowProc() anymore.
SDL_WINDOWS_JoystickDriver depends on callbacks in SDL_RAWINPUT_JoystickDriver
and SDL_HIDAPI_JoystickDriver being available. It also manages the common
WindowProc used for joystick detection in both WINDOWS and RAWINPUT drivers.
If we don't tear them down backwards, there's a window of time where we could
invoke RAWINPUT_WindowProc() after RAWINPUT_JoystickQuit() was called.
- SDL_CLOCK_GETTIME now defaults to ON to match autotools build
- Add detection of float.h and Xdbe
- Fix detection of pthread_setname_np() (requires _GNU_SOURCE)
- Move SDL_USE_IME definition into SDL_config.h.cmake
Since the haptic subsystem is usually initialized after the joystick subsystem,
the initial calls to HapticMaybeAddDevice() from inside SDL_JoystickInit() will
arrive too early to be handled by the haptic subsystem. We need to add those
haptic devices for those already present joysticks ourselves.
The joystick subsystem has complex precedence logic to deal multiple competing
backends like XInput, RawInput, and WGI. Let it fire the MaybeAdd callbacks
for joystick devices, since it knows which backend will end up managing them.
This resolves a situation where the RawInput joystick backend would take
control of an XInput device but the XInput haptic backend would still create
a haptic device. Since the XInput joystick backend didn't own the underlying
joystick device, we'd end up with an orphaned haptic device that didn't work
with SDL_HapticOpenFromJoystick() on the associated joystick device.
A racing reader could read from our fd between SDL_IOReady()/X11_Pending()
and our call to XNextEvent() which will cause XNextEvent() to block for
more data. Avoid this by using XCheckIfEvent() which will never block.
This also fixes a bug where we could poll() for data, even when events were
already read and pending in the queue. Unlike the Wayland implementation,
this isn't totally thread-safe because nothing prevents a racing reader
from reading events into the queue between our XCheckIfEvent() and
SDL_IOReady() calls, but I think this is the best we can do with Xlib.
Enabling the RawInput backend causes SDL_XINPUT_Enabled() to return false.
That causes WGI and DInput backends to take ownership of XInput-compatible
controllers, because they think there's no XInput-specific backend enabled.
In WGI's case, it will actually race with RawInput to open the device. By
properly excluding XInput devices from WGI, we can ensure that the sets of
devices managed by WGI and RawInput don't intersect. This makes the race
harmless, since they'll never both go after the same device.
The Xbox One driver stack doesn't propagate the VID/PID down to the
HID devices that end up in the GetRawInputDeviceList() output. This
means we end up matching against the wrong VID/PID and can't properly
exclude Xbox One controllers from WGI.
Fortunately, it is possible to walk back up the device tree to find
the parent with the matching VID/PID.
__has_include() was added in VS 2017 15.3, so this works out to essentially
the same _MSC_VER >= 1911 check we had before for MSVC but works for non-MSVC
compilers also.
The D3D11 renderer requires Direct3D 11.1 (d3d11_1.h), not Direct3D 11.0
(d3d11.h). In terms of SDKs, that's the Windows 8 SDK or later.
We should probably rename HAVE_D3D11_H...
Add a new flag to avoid suppressing EINTR in SDL_IOReady(). Pass the
flag in WaitEventTimeout() to ensure that a SIGINT will wake up
SDL_WaitEvent() without another event coming in.
We can have spurious wakeups in WaitEventTimeout() due to Wayland events
that don't end up causing us to generate an SDL event. Fortunately for us,
SDL_WaitEventTimeout_Device() handles this situation properly by calling
WaitEventTimeout() again with an adjusted timeout.
Wayland provides the prepare_read()/read_events() family of APIs for
reading from the display fd in a deadlock-free manner across multiple
threads in a multi-threaded application. Let's use those instead of
trying to roll our own solution using a mutex.
This fixes an issue where a call to SDL_GL_SwapWindow() doesn't swap
buffers if it happens to collide with SDL_PumpEvents() in the main
thread. It also allows coexistence with other code or toolkits in
our process that may want read and dispatch events themselves.
