This makes the joystick locking more robust by holding the lock while updating joysticks.
The lock should be held when calling any SDL joystick function on a different thread than the one calling SDL_PumpEvents() and SDL_JoystickUpdate().
It is now possible to hold the lock while reinitializing the joystick subsystem, however any open joysticks will become invalid and potentially cause crashes if used afterwards.
Fixes https://github.com/libsdl-org/SDL/issues/6063
This is now used as a crc field in the mapping rather than directly in mapping guids, for better mapping compatibility between versions of SDL.
Added SDL_GetJoystickGUIDInfo() to get device information encoded in a joystick GUID, so that mapping programs can clear the CRC from the GUID when generating mappings.
sort_controllers.py has been updated to extract the CRC from mappings created by older mapping programs and convert it into the new crc field. It will also take the CRC into account when checking for duplicate mappings.
Also regenerated the GUIDs for the PS2/PSP/Vita controller mappings, fixing https://github.com/libsdl-org/SDL/issues/6151
- This allows looking up the display index for an arbitrary location rather than requiring an active window to do so.
- This change also reimplements the fallback display lookup that found the display with center closest to the window's center to instead find the display rect edge
closest to the window center (this was done in the almost identical display lookup used in SDL_windowsmodes.c, which now uses `SDL_GetPointDisplayIndex`). In
practice this should almost never be hit as it requires the window's center to not be enclosed by any display rect.
* Added support for mini-gamepad mode for Joy-Con controllers, matching the mapping for hid-nintendo on Linux and iOS 16
* Added the ability to merge left and right Joy-Con controllers into a single Pro-style controller
* Added the hint SDL_HINT_JOYSTICK_HIDAPI_SWITCH_COMBINE_JOY_CONS to control this merging functionality
* Removed the hint SDL_HINT_JOYSTICK_HIDAPI_JOY_CONS
Extend the SDL_WINDOW_ALLOW_HIGHDPI flag documentation to stress the importance of querying the window drawable size after every window event to avoid rendering issues in a mixed-DPI environment.
The documentation doesn't state that the argument is ever modified,
and no implementation does so currently.
This is a non-breaking change to guarantee as much to callers.
* Xbox GDK support (14 squashed commits)
* Added basic keyboard testing
* Update readme
* Code review fixes
* Fixed issue where controller add/removal wasn't working (since the device notification events don't work on Xbox, have to use the joystick thread to poll XInput)
Also added test functions for multi-line debug text display
Currently this only supports ASCII, as the font doesn't have the correct Latin-1 characters
Without using <inttypes.h>, SDL_PRIx64 will expand to llx, but on 64-bit
FreeBSD platforms (u)int64_t is `(usigned) long`:
SDL_test_memory.c:261:77: error: format specifies type 'unsigned long long' but the argument has type 'Uint64' (aka 'unsigned long') [-Werror,-Wformat]
This commit updates config_minimal.h to also assume presence of inttypes.h
for everything except old MSVC.
Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to
change the SDL coordinate system units to be DPI-scaled points, rather
than pixels everywhere.
This means windows will be appropriately sized, even when created on
high-DPI displays with scaling.
e.g. requesting a 640x480 window from SDL, on a display with 125%
scaling in Windows display settings, will create a window with an
800x600 client area (in pixels).
Setting this to "1" implicitly requests process DPI awareness
(setting SDL_WINDOWS_DPI_AWARENESS is unnecessary),
and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.
The hint allows setting a specific DPI awareness ("unaware", "system", "permonitor", "permonitorv2").
This is the first part of High-DPI support on Windows ( https://github.com/libsdl-org/SDL/issues/2119 ).
It doesn't implement a virtualized SDL coordinate system, which will be
addressed in a later commit. (This hint could be useful for SDL apps
that want 1 SDL unit = 1 pixel, though.)
Detecting and behaving correctly under per-monitor V2
(calling AdjustWindowRectExForDpi where needed) should fix the
following issues:
https://github.com/libsdl-org/SDL/issues/3286https://github.com/libsdl-org/SDL/issues/4712
Add the hint "SDL_VIDEO_WAYLAND_MODE_EMULATION", which can be used to disable mode emulation under Wayland. When disabled, only the desktop and/or native display resolution is exposed.
- SDL_JoystickGUID -> SDL_GUID (though we retain a type alias)
- Operations for GUID <-> String ops are now in
src/SDL_guid.c and include/SDL_guid.h
- The corresponding Joystick operations delegate to SDL_guid.c
- Added test/testguid.c
Added the ability to specify a name and the product VID/PID for a virtual controller
Also added a test case to testgamecontroller, if you pass --virtual as a parameter
* Add changes from code review by @ccawley2011, #5597, overall cleanup
* Update N-Gage README, minor cleanup and rephrasing
* Call SDL_SetMainReady() before calling SDL_main, return SDL_main instead of main
This can be used to check whether untrusted sizes would cause overflow
when used to calculate how much memory is needed.

For stable releases, this gives us the ability to make bugfix-only point
releases such as 2.24.1 if we want to, and distinguish between them
programmatically. For example, this ability could have been useful after
2.0.16 to fix Xwayland regressions, and after 2.0.18 to fix event loop
regressions.
For development releases, this gives us the ability to make multiple
prereleases during the same feature cycle, and distinguish between them
programmatically. For example, this would have been useful during 2.0.22
development, which went through three prereleases before reaching the
final release.

Now that we've said this will be removed from SDL 3, we're free to use
any encoding that is compatible with existing SDL versions and will still
compare correctly for all SDL 2 version numbers. This allows the SDL 2
minor version to go beyond 1 digit, limited only by the size of
SDL_version.minor (which is 8 bits), making the largest possible version
number 2.255.99.
The patchlevel (micro version) is still limited to 2 digits.
Signed-off-by: Simon McVittie <smcv@collabora.com>
The encoding used in SDL_VERSIONNUM (e.g. 2.0.22 -> 2022) cannot
represent 2-digit minor versions without overflowing from the hundreds
digit into the thousands digit, which produces confusing version
numbers that will compare incorrectly when the major version is increased
to 3.
However, we can sidestep this problem by declaring that SDL_VERSIONNUM
will no longer be present in SDL 3, which means it only needs to be able
to represent SDL 2 version numbers losslessly.
Signed-off-by: Simon McVittie <smcv@collabora.com>
This comparison normally happens at compile-time, not at runtime, so
it doesn't matter if it isn't optimal. This avoids incorrect comparison
if the minor version in SDL_COMPILEDVERSION and SDL_VERSIONNUM has more
than one digit, which would cause it to overflow from the hundreds place
into the thousands place.

Case fallthrough warnings can be suppressed using the __fallthrough__
compiler attribute. Unfortunately, not all compilers have this
attribute, or even have __has_attribute to check if they have the
__fallthrough__ attribute. [[fallthrough]] is also available in C++17
and the next C2x, but not everyone uses C++17 or C2x.
So define the SDL_FALLTHROUGH macro to deal with those problems - if we
are using C++17 or C2x, it expands to [[fallthrough]]; else if the
compiler has __has_attribute and has the __fallthrough__ attribute, then
it expands to __attribute__((__fallthrough__)); else it expands to an
empty statement, with a /* fallthrough */ comment (it's a do {} while
(0) statement, because users of this macro need to use a semicolon,
because [[fallthrough]] and __attribute__((__fallthrough__)) require a
semicolon).
Clang before Clang 10 and GCC before GCC 7 have problems with using
__attribute__ as a sole statement and warn about a "declaration not
declaring anything", so fall back to using the /* fallthrough */ comment
if we are using those older compiler versions.
Applications using SDL are also free to use this macro (because it is
defined in begin_code.h).
All existing /* fallthrough */ comments have been replaced with this
macro. Some of them were unnecessary because they were the last case in
a switch; using SDL_FALLTHROUGH in those cases would result in a compile
error on compilers that support __fallthrough__, for having a
__attribute__((__fallthrough__)) statement that didn't immediately
precede a case label.

This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".
Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:
1. The coordinate system has been changed so that `rect` is _window_ relative
and not _screen_ relative, making it easier to implement without having
global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
`window`, this has been removed as it was an unused feature anyhow.
Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.
This prevents conflicts with hidapi linked with applications, as well as allowing applications to make use of HIDAPI on Android and other platforms that might not normally have an implementation available.
__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...
It's marked as being a public symbol internally, however, it was missing from the header files and not visible in the shared library. This adds it to the necessary headers and to the DynAPI list to expose it for use by applications.

Note that this removes the timeGetTime() fallback on Windows; it is a
32-bit counter and SDL2 should never choose to use it, as it only is needed
if QueryPerformanceCounter() isn't available, and QPC is _always_ available
on Windows XP and later.
OS/2 has a similar situation, but since it isn't clear to me that similar
promises can be made about DosTmrQueryTime() even in modern times, I decided
to leave the fallback in, with some heroic measures added to try to provide a
true 64-bit tick counter despite the 49-day wraparound. That approach can
migrate to Windows too, if we discover some truly broken install that doesn't
have QPC and still depends on timeGetTime().
Fixes#4870.
SDL_config.h *can* define SDL_JOYSTICK_WGI. On builds with the Windows

(This probably isn't right on truly ancient versions of Borland C, but it
should cover things from the last decade or so, I hope.)
(possibly) Fixes#1673.
We don't use it, it was a leftover from 1.2, I think, and it doesn't exist
on Solaris, so this should hopefully fix the build there.
This also means we don't need the configure/cmake checks for
SDL_VIDEO_DRIVER_X11_CONST_PARAM_XEXTADDDISPLAY, so that was removed also.
Fixes#1666.
Vista and later provide the SleepConditionVariableCS() function for this.
Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to
SDL_syscond_cv.c which better reflects the implementation of condition
variables rather than the implementation of mutexes.
Fixes#4051.
In the future, we might want to support special swap intervals. To
prevent applications from expecting nonzero values of vsync to be the
same as "on", fail with SDL_Unsupported() if the value passed is neither
0 nor 1.
Currently, if an application wants to toggle VSync, they'd have to tear
down the renderer and recreate it. This patch fixes that by letting
applications call SDL_RenderSetVSync().
This is the same as the patch in #3673, except it applies to all
renderers (including PSP, even thought it seems that the VSync flag is
disabled for that renderer). Furthermore, the renderer flags also change
as well, which #3673 didn't do. It is also an API instead of using hint
callbacks (which could be potentially dangerous).
Closes#3673.
See SDL bug #4703. This implements two new hints:
- SDL_APP_NAME
- SDL_SCREENSAVER_INHIBIT_ACTIVITY_NAME
The former is the successor to SDL_HINT_AUDIO_DEVICE_APP_NAME, and acts
as a generic "application name" used both by audio drivers and DBUS
screensaver inhibition. If SDL_AUDIO_DEVICE_APP_NAME is set, it will
still take priority over SDL_APP_NAME.
The second allows the "activity name" used by
org.freedesktop.ScreenSavver's Inhibit method, which are often shown in
the UI as the reason the screensaver (and/or suspend/other
power-managment features) are disabled.
Add a function to clamp a value to a range.
SDL_clamp(x, a, b) is equivalent to SDL_min(a, SDL_max(x, b)): it
ensures that x is not smaller than a, nor larger than b.
While, as best I can tell, this isn't actually standardised anywhere,
it's a very useful function/macro to have.
The __clang_major__ and __clang_minor__ macros provide a marketing
version, which is not necessarily comparable for clang distributions
from different vendors[1]. In practice, the versioning scheme for
Apple's clang is indeed completely different to that of the llvm.org
releases. It is thus preferable to check for features directly rather
than comparing versions.
In this specific case, __builtin_bswap16 was being used with older
Apple clang versions that don't support it.

This is needed to support CHERI, and thus Arm's experimental Morello
prototype, where pointers are implemented using unforgeable capabilities
that include bounds and permissions metadata to provide fine-grained
spatial and referential memory safety, as well as revocation by sweeping
memory to provide heap temporal memory safety.
The referential safety is enforced through the use of tagged memory, and
there is only a single tag bit per capability-sized word, meaning it is
impossible to store capabilities at unaligned locations, either getting
a trap on load/store or the validity tag being stripped when
round-tripepd through memory.
Since this is a new ABI for which SDL has never been compiled before, we
do not need to be concerned with this compatibility measure, so just
don't pack the struct for CHERI architectures.
This code is inherently rather dubious anyway; if MSVC and GCC disagree
on struct layout when targeting Windows then that is a bug in GCC, but
likely extends from the bogus #pragma pack directives for MSVC in
begin_code.h, which will force types to be *underaligned* (and is
attempting to work around something that is fundamentally a broken idea
to be doing). In particular 8-byte-aligned types will be underaligned to
4 bytes, but only on MSVC. Since that code is not used for GCC that is
probably the cause of the struct layout discrepancy, and there are
likely other instances of that throughout SDL. Moreover, the supposed
fix here is not in fact a fix, as now GCC will think SDL_AudioCVT is
only 1-byte-aligned but MSVC will think it's 4-byte or 8-byte-aligned,
meaning ABI incomatibility is introduced by this change. However,
removing it would break ABI compatibility for purely-GCC-compiled code
(as old binaries would see the struct as 1-byte-aligned and new binaries
would see the struct as 8-byte-aligned) so SDL is stuck with this until
it bumps its ABI.
This is needed to support CHERI, and thus Arm's experimental Morello
prototype, where pointers are implemented using unforgeable capabilities
that include bounds and permissions metadata to provide fine-grained
spatial and referential memory safety, as well as revocation by sweeping
memory to provide heap temporal memory safety.

With that driver installed it mimics Xbox One controller and works via XInput under Windows.
Under DInput this controller is not usable at all.
In a more ideal world, we'd use the appropriate `__attribute__` here, but
it's one thing in a public header that probably shouldn't be there at all, so
this is good enough for now.
Fixes#4307.
If you hide a window on Mutter, for example, the compositor never requests
new frames, which will cause Mesa to block forever in eglSwapBuffers to
satisfy the swap interval.
We now always set the swap interval to 0 and manage this ourselves, handing
the frame to Wayland when it requests a new one, and timing out at 10fps just
to keep apps moving if the compositor wants no frames at all.
My understanding is that other protocols are coming that might improve upon
this solution, but for now it solves the total hang.
Fixes#4335.

The llvm-mingw project includes cross-compilers targeting ARM: https://github.com/mstorsjo/llvm-mingw/releases
Currently, compilation fails with this configuration, because neon features are used as long as __ARM_NEON is defined, but arm_neon.h was not included.
This should not change anything at all within the compiled library, but it does make the header file easier to read for non-C programmers who don't expect an octal value.
In some cases, it can be useful to have the KMSDRM backend even if it cannot
be used for rendering. An app may want to use SDL for input processing while
using another rendering API (such as an MMAL overlay on Raspberry Pi) or
using its own code to render to DRM overlays that SDL doesn't support.
This also moves the check for DRM master to an earlier point where we can fail
initialization of the backend, rather than allowing the backend to initialize
then failing the creation of a window later.
SDL has been missing a bunch of these 'isX' functions for some time,
where X is some characteristic of a given character.
This commit adds the rest of them to the SDL stdlib, so now we have:
- SDL_isalpha()
- SDL_isalnum()
- SDL_isblank()
- SDL_iscntrl()
- SDL_isxdigit()
- SDL_ispunct()
- SDL_isprint()
- SDL_isgraph()
The DJGPP compiler emits many warnings for conflicts between print
format specifiers and argument types. To fix the warnings, I added
`SDL_PRIx32` macros for use with `Sint32` and `Uint32` types. The macros
alias those found in <inttypes.h> or fallback to a reasonable default.
As an alternative, print arguments could be cast to plain old integers.
I opted slightly for the current solution as it felt more technically correct,
despite making the format strings more verbose.

In SDL_cpuinfo.h it seems like <intrin.h> is not included when __clang__ is defined, as the comment in the file explicitly reads:
"Many of the intrinsics SDL uses are not implemented by clang with Visual Studio"
However, the SDL_endian.h header does include <intrin.h> without any precautions like:
>#ifdef _MSC_VER
>#include <intrin.h>
>#endif
Maybe it should be changed to something like:
>#ifdef _MSC_VER
>#ifndef __clang__
>#include <intrin.h>
>#endif
>#endif
By default, we will minimize the window when we receive Alt+Tab with a
full-screen keyboard grabbed window to allow the user to escape the
full-screen application.
Some applications like remote desktop clients may want to handle Alt+Tab
themselves, so provide an opt-out via SDL_HINT_ALLOW_ALT_TAB_WHILE_GRABBED=0.
This adds SDL_SetWindowKeyboardGrab(), SDL_GetWindowKeyboardGrab(),
SDL_SetWindowMouseGrab(), SDL_GetWindowMouseGrab(), and new
SDL_WINDOW_KEYBOARD_GRABBED flag. It also updates the test harness to exercise
this functionality and makes a minor fix to X11 that I missed in
https://hg.libsdl.org/SDL/rev/02a2d609369b
To fit in with this new support, SDL_WINDOW_INPUT_CAPTURE has been renamed to
SDL_WINDOW_MOUSE_CAPTURE with the old name remaining as an alias for backwards

New hint to let the user opt out of having Switch controllers' Home button lit when opened.
This is more consistent with the Switch itself (which doesn't light the button normally) and may be preferred by users who may disconnect their controller without letting the application close it.
I think this warrants a Switch-specific hint because the default behaviour is unusual (inconsistent with using a Switch controller on a Switch itself or with some other programs on PC), and because of that it's distinct from other lights (the player number on Switch controllers and the player colour on PlayStation controllers).
Existing SDL applications may not know about the need to set a specific
hint to enable rumble on PS5 controllers, even though they may already
set the equivalent SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE hint for PS4
controller rumble support.
Rather than requiring those developers update their apps, let's use the
SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE value as an indication of the behavior
they are expected for all PlayStation controllers.

In some cases, need create EGLWindow with SDLWindow. In X11 i can get pointer to NativeWindow from **struct SDL_SysWMinfo wmInfo**
```C++
struct SDL_SysWMinfo wmInfo;
SDL_GetWindowWMInfo(ptSDLWindow, &wmInfo)
#if defined(__unix__) && defined(SDL_VIDEO_DRIVER_X11)
nativeWindow=(EGLNativeWindowType)wmInfo.info.x11.window;
nativeDisplay=(EGLNativeDisplayType)wmInfo.info.x11.display;
#endif
```
than i can create EGLSurface
```
eglCreateWindowSurface(nativeDisplay, EGL_CONFIG, nativeWindow, SURFACE_ATTRIBUTES);
```
in Wayland i can do it with same way, just need pointer to **EGLWindow**, we already have pointer to **wl_display** from **SDL_sysWMInfo**, need add to **wl** struct in SDL_SysWMInfo another pointer to **struct wl_egl_window *egl_window;**. And in wayland backend, in function **Wayland_GetWindowWMInfo** return pointer to **egl_window** from **SDL_WindowData**
Now i use patched statically built SDL2 in port of Quake 2 GLES2 for SailfishOS (it use QtWayland):
link to SDL2 commit and changed string for patch:
- 6858a618cd
- b1e29e87b9/SDL2/src/video/wayland/SDL_waylandwindow.c (L463)
link to use in Quake2 port:
1. here i get pointer to EGLNativeWindowType: 6d94fedb1b/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c (L319)
2. then use it for create EGLSurface: 6d94fedb1b/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c (L391)

This patch adds a written-from-scratch WSCONS driver for OpenBSD. It does not have hardcoded keymaps, and it features mouse support when wsmux is available.
For this to work, it needs access to the /dev/wskbd* devices which are not available to non-root users by default. Access to those can be granted by changing /etc/fbtab to give the logging user the ownership of those devices.
__builtin_bswap32/64 were introduced in GCC 4.3. __builtin_bswap16 was
not available on x86 until GCC 4.8 due to a bug.
__builtin_bswap32/64 were introduced in Clang 2.6. __builtin_bswap16
was introduced in Clang 3.2.

I tested building commit http://hg.libsdl.org/SDL/rev/7adf3fdc19f3 on Mac Catalyst and found some issues:
* MTLFeatureSet_iOS_* enums aren't available under Mac Catalyst.
* OpenGL ES is unavailable under Mac Catalyst.
* Some Metal features are available under Catalyst but not iOS, such as displaySyncEnabled.
* Set Metal as the default renderer on Mac Catalyst
Attaching a patch that will make SDL2 build for Mac Catalyst.
Is automatically used when the SRW SDL_mutex implementation is active.
Otherwise falls back to the generic implementation.
v2: - Rebase onto master fa3ea1051a4b

stdlib: Added SDL_round, SDL_roundf, SDL_lround and SDL_lroundf
The default implementation is based on the one used in the Windows RT video driver.
Keep Semaphore Kernel Object impl for Windows 7 and older - choose at runtime
v2: - Fix mixed int/LONG types
- Reorder definitions
- Add missing include
v3: - Use `GetModuleHandle()` to load the API Set
v2: - Add SRW definitions as suggested by Ozkan Sezer
Allows building against older platform headers.
- Rename "hidden" function parameter `mutex_` to `_mutex`
v3: - Use GetModuleHandle instead of LoadLibrary
- Fix typo in comment
Added a hint to control whether a separate thread should be used for joystick events.
This is off by default because dispatching messages in other threads appears to cause problems on some versions of Windows.

Xcode11 and ios13 added support for metal simulator.
Here is a quick and dirty patch to enable it. Pretty early and only tested on a few samples for now. Required mostly to enable metal support on correct version of ios, generate simulator compatible shaders and enforce buffer alignments on simulator (same as osx).

Evdev headers aren't actually included in the base system (well, it has a private copy), they are available through the devel/evdev-proto port instead. We also have devel/libinotify and devel/libudev-devd shims, I didn't verify whether they work with SDL.

As it is, SDL2's built-in config on macOS for Metal excludes Apple Silicon. This is due to thinking that the 64-bit Mac platform would always be x86_64. My patch fixes this by using the catch-all of 64-bit platforms.

This patch adds support to the GameController framework on macOS Big Sur and later, adding support for MFi controllers as well as rumble support for PS4 and Xbox One. There is some code to make sure that the IOKit joystick handler doesn't include two controllers at once.
While the GameController framework is present in earlier versions of macOS, there was no public, approved way of checking if a specific IOHIDDevice is a controller that GameController could handle. This was changed in Big Sur.
Added support for the PS4 controller gyro and accelerometer on iOS and HIDAPI drivers
Also fixed an issue with the accelerometer on iOS having inverted axes
The configure/cmake scripts were checking for these functions but we didn't
have the SDL_config.h.* pieces in place. The other config headers are best
guesses.
As the name suggests, the hint should only apply to SDL_THREAD_PRIORITY_TIME_CRITICAL
The resulting priorities for my current distro result in these values:
| High | Time Critical
Hint |--------------|-----------------
0 | P=10 N=-10 | P=5 N=-15
1 | P=10 N=-10 | P=-21 N=0
