Raw Normal View History

Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

This is a list of major changes in SDL's version history.
Re-added the CRC to the joystick guid 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

---------------------------------------------------------------------------
Updated SDL_syswm.h for SDL 3.0 * The header is no longer dependent on SDL build configuration * The structures are versioned separately from the rest of SDL * SDL_GetWindowWMInfo() now returns a standard result code and is passed the version expected by the application * Updated WhatsNew.txt and docs/README-migration.md with the first API changes in SDL 3.0

General:
Switch header convention from `#include "SDL.h"` to `#include <SDL3/SDLh>` I ran this script in the include directory: ```sh sed -i '' -e 's,#include "\(SDL.*\)",#include <SDL3/\1>,' *.h ``` I ran this script in the src directory: ```sh for i in ../include/SDL3/SDL*.h do hdr=$(basename $i) if [ x"$(echo $hdr | egrep 'SDL_main|SDL_name|SDL_test|SDL_syswm|SDL_opengl|SDL_egl|SDL_vulkan')" != x ]; then find . -type f -exec sed -i '' -e 's,#include "\('$hdr'\)",#include <SDL3/\1>,' {} \; else find . -type f -exec sed -i '' -e '/#include "'$hdr'"/d' {} \; fi done ``` Fixes https://github.com/libsdl-org/SDL/issues/6575
2022-11-26 21:43:38 -07:00
* SDL headers should now be included as `#include <SDL3/SDL.h>`
WhatsNew.txt should be new features in SDL 3.0 docs/README-migration.md will cover API changes and removals since SDL 2.0
2022-12-27 11:06:45 -07:00
* Many functions and symbols have changed since SDL 2.0, see the [migration guide](docs/README-migration.md) for details
Don't add symbol renaming to WhatsNew.txt
2022-12-27 11:00:10 -07:00
* The preprocessor symbol __MACOSX__ has been renamed __MACOS__
* The preprocessor symbol __IPHONEOS__ has been renamed __IOS__
* SDL_stdinc.h no longer includes stdio.h, stdlib.h, etc., it only provides the SDL C runtime functionality
Moved SDL_intrin.h back into the public headers for application use
2023-01-10 16:50:35 -07:00
* SDL_intrin.h now includes the intrinsics headers that were in SDL_cpuinfo.h
WhatsNew.txt should be new features in SDL 3.0 docs/README-migration.md will cover API changes and removals since SDL 2.0
2022-12-27 11:06:45 -07:00
* Added SDL_CreateSurface() and SDL_CreateSurfaceFrom() which replace SDL_CreateRGBSurface*(), and can also be used to create YUV surfaces
Removed SDL_HasGamepads(), SDL_HasJoysticks(), and SDL_HasSensors() Also cleaned up logic for whether we need to poll for events: - We need to periodically poll for joysticks to handle hotplug. - We need to frequently poll for joysticks and sensors when they're open so their state can be updated
2022-12-30 00:07:30 -07:00
* Added SDL_GetJoysticks(), SDL_GetJoystickInstanceName(), SDL_GetJoystickInstancePath(), SDL_GetJoystickInstancePlayerIndex(), SDL_GetJoystickInstanceGUID(), SDL_GetJoystickInstanceVendor(), SDL_GetJoystickInstanceProduct(), SDL_GetJoystickInstanceProductVersion(), and SDL_GetJoystickInstanceType() to directly query the list of available joysticks
* Added SDL_GetGamepads(), SDL_GetGamepadInstanceName(), SDL_GetGamepadInstancePath(), SDL_GetGamepadInstancePlayerIndex(), SDL_GetGamepadInstanceGUID(), SDL_GetGamepadInstanceVendor(), SDL_GetGamepadInstanceProduct(), SDL_GetGamepadInstanceProductVersion(), and SDL_GetGamepadInstanceType() to directly query the list of available gamepads
* Added SDL_GetSensors(), SDL_GetSensorInstanceName(), SDL_GetSensorInstanceType(), and SDL_GetSensorInstanceNonPortableType() to directly query the list of available sensors
Don't add symbol renaming to WhatsNew.txt
2022-12-27 11:00:10 -07:00
* SDL_GetTicks() now returns a 64-bit value and the tick values should be directly compared instead of using the SDL_TICKS_PASSED macro
* Added SDL_GetTicksNS() to return the number of nanoseconds since the SDL library initialized
* Added SDL_DelayNS() to specify a delay in nanoseconds, to the highest precision the system will support
* The timestamp member of the SDL_Event structure is now in nanoseconds, filled in with the time the event was generated, or the time it was queued if that's not available
Added SDL_modf() and SDL_modff() This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement. e.g. static float dx_frac, dy_frac; float dx, dy; /* Accumulate new motion with previous sub-pixel motion */ dx = event.motion.xrel + dx_frac; dy = event.motion.yrel + dy_frac; /* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */ dx_frac = SDL_modff(dx, &dx); dy_frac = SDL_modff(dy, &dy); if (dx != 0.0f || dy != 0.0f) { ... }
2022-12-29 22:39:08 -07:00
* Added SDL_modf() and SDL_modff() to separate the whole and fractional portions of a floating point number
Replaced SDL_SIMDAlloc(), SDL_SIMDRealloc(), and SDL_SIMDFree() with SDL_aligned_alloc() and SDL_aligned_free() Fixes https://github.com/libsdl-org/SDL/issues/5641
2023-01-09 18:42:16 -07:00
* Added SDL_aligned_alloc() and SDL_aligned_free() to allocate and free memory with a given alignment
Add SDL_GetRenderVSync (see #6495) (#6965)
2023-01-02 12:21:02 -07:00
* Added SDL_GetRenderVSync() to get vsync of the given renderer
Add SDL_PlayAudioDevice() to play audio. Remove pause_on param from SDL_PauseAudioDevice()
2023-01-06 05:59:45 -07:00
* Added SDL_PlayAudioDevice() to start audio playback
Add SDL_ConvertAudioSamples() helper function
2023-01-23 00:24:49 -07:00
* Added SDL_ConvertAudioSamples() to convert audio samples from one format to another
