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().

Added SDL_DROPBEGIN and SDL_DROPCOMPLETE events, plus window IDs for drops. This allows an app to know when a set of drops are coming in a grouping of some sort (for example, a user selected multiple files and dropped them all on the window with a single drag), and when that set is complete. This also adds a window ID to the drop events, so the app can determine to which window a given drop was delivered. For application-level drops (for example, you launched an app by dropping a file on its icon), the window ID will be zero.

Fixed bug 3583 - X11 touch device can be permanently lost Volumetric In X11 the SDL error "Unknown touch device" can occur after which the application stops recognizing touch events. For a kiosk-type application this results in a hang as far as the user is concerned. This is reproducible on HP Z220/Z230/Z240 workstations by swapping USB cables for a while and it also occurs with no physical changes, probably due to USB device power management. A workaround is to make SDL re-enumerate the touch devices like it does at startup. A patch is attached.

video: Let video targets optionally decide their default OpenGL configs. This is necessary because the Raspberry Pi is a strange beast, that believes it has OpenGL support (through glX?) but generally has GLES2 support. So when using the raspberry video target, we need to force this to default to a GLES2 context, or by default SDL_CreateWindow() will fail, deep down when it tries to load the proper GL library. Fixes testsprite2 (and basically everything else that wasn't testgles2) when run on a Raspberry Pi without a X server. Please note that other targets might also need this filled in, the Raspberry Pi is just the most prominent and readily-available System-On-A-Chip style thing on my desk. :)

metal: Added some support interfaces to Apple's Metal API (thanks, Caleb!). Caleb Cornett's comments: "A few weeks ago, Alex added a partial Metal API to SDL2: https://hg.libsdl.org/SDL/rev/22c8e7cd8d38 I noticed it was missing a few features that would help Metal become a first-class citizen in SDL, so I went ahead and wrote them! Here are the new APIs: 1. SDL_WINDOW_METAL flag for SDL_CreateWindow(). This allows the programmer to specify that they intend to create a window for use with SDL_MetalView. The flag is used to ensure correct usage of the API and to prevent accidentally defaulting to OpenGL on iOS. 2. SDL_Metal_GetLayer(). This function takes a SDL_MetalView and returns a pointer to the view's backing CAMetalLayer. This simplifies things considerably, since in the current version of the SDL_Metal API the programmer is required to bridge-cast a SDL_MetalView handle to an NSView or UIView (depending on the platform) and then extract the layer from there. SDL_Metal_GetLayer automatically handles all of that, making the operation simple and cross-platform. 3. SDL_Metal_GetDrawableSize(). This function already exists in the current SDL_Metal API (and is used behind-the-scenes for SDL_Vulkan_GetDrawableSize on Apple platforms) but was not publicly exposed. My patch exposes this function for public use. It works just like you'd expect. Tested on macOS 10.14 and iOS 12.4." Fixes Bugzilla #4796.

Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.

opengl: Allow SDL_GL_MakeCurrent() to accept a NULL window (thanks, Martin!). This allows you to bind surfaceless contexts on a background thread to, for example, load assets in a separate context, for platforms that have different requirements about sharing surfaces, etc. Martin's notes on the matter: "Here's a patch that enables passing NULL windows to SDL_GL_MakeCurrent, if the involved APIs allow it. Currently, this is only the case for EGL, and even then only if some specific extensions are present (which they usually are). If "surfaceless" contexts are not supported, SDL_GL_MakeCurrent continues to generate an error (albeit with a more specific error message than it used to), so this should not break anything that wasn't broken before." (Please see https://bugzilla.libsdl.org/show_bug.cgi?id=3695 for more discussion.) Fixes Bugzilla #3695.

Fixed bug 3690 - SDL2 KMS/DRM render context support Manuel The attached patch adds support for KMS/DRM context graphics. It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation. Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition. X86 systems use KMS right away in every current GNU/Linux system. Simple build instructions: $./autogen.sh $./configure --enable-video-kmsdrm $make

Fixed bug 4890 - Add hint for SDL that the graphics context is externally managed Aaron Barany Add SDL_HINT_VIDEO_EXTERNAL_CONTEXT hint to notify SDL that the graphics context is external. This disables the automatic context save/restore behavior on Android and avoids using OpenGL by default when SDL_WINDOW_VUKLAN isn't set. When the application wishes to manage the OpenGL contexts on Android, this avoids cases where SDL unbinds the context and creates new contexts, which can interfere with the application's operation. When using Vulkan and Metal renderer implementations, this avoids SDL forcing OpenGL to be enabled on certain platforms. While using the SDL_WINDOW_VULKAN flag can be used to achieve the same thing, it also causes Vulkan to be loaded. If the application uses Vulkan directly, this is not necessary, and fails window creation when using Metal due to Vulkan not being present. (assuming MoltenVK isn't installed)

Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11 Mark Callow The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile: - Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can say to use the OpenGL ES driver & EGL rather than the Open GL driver. (For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects. With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.
