This was reproducible by running an SDL app on the console from an ssh login. In this case the terminal wasn't owned by the user running the app, so we were using the default keymap, which didn't have state transitions defined for ctrl and alt, so once we entered that state keypresses would no longer transition out of that state, nor would they generate text.
As a workaround, we'll just reset to the default shift state if that happens, which means we'll get text for keys pressed while ctrl is held down, but I don't think that's a big problem.
Note that in this case we also can't mute the keyboard, so the keypresses go to the console, which probably isn't what you want...
Expand SDLActivity::SDLSurface::surfaceChanged() callback to grab the panel width and height at the same time and pass that along to the native code. Only works on API 17+. Duplicates surface dimensions whenever it fails.
Add Android_DeviceWidth/Android_DeviceHeight globals to native code.
Disambiguate Android_ScreenWidth/Android_ScreenHeight -> Android_SurfaceWidth/Android_SurfaceHeight
Use device width/height for all display mode settings.
This is commented out in SDLActivity.java, with the note #CURSORIMPLEENTATION because it requires API 24, which is higher than the minimum required SDK

The following patch defines _WIN32_WINNT_WIN7 if it is not already
defined in core/windows/SDL_windows.c, similar to what is already
there for _WIN32_WINNT_VISTA.

After updating from 2.0.5 to 2.0.7, Ibus not work anymore(fcitx still works).
Compare with 2.0.5, there are two issues in SDL_ibus.c.
1, SetupConnection always return SDL_FALSE in 2.0.7.
2, 'SetCapabilities' method should be called on 'ibus_conn'.
Patch attached.

dbus_shutdown() is a debug feature which closes all global resources in the dbus library. Calling this should be done by the app, not a library, because if there are multiple users of dbus in the process then SDL could shut it down even though another part is using it.
For example, i had an issue with this in mGBA, which uses both Qt and SDL, both using libdbus. I had a session bus, but no system bus (this was in a flatpak sandbox), and when SDL_DBus_Init() failed to init the system bus it called dbus_shudown() and continued on. This caused issues for Qt when running due to its session bus connections having disappeared beneath it.
SDL now builds with gcc 7.2 with the following command line options:
-Wall -pedantic-errors -Wno-deprecated-declarations -Wno-overlength-strings --std=c99

HAVE_POLL is correctly defined in SDL_config.h when running configure. However, in the only place where it's used, it's undefined at the start of the file.

As of 2.0.6, all of my games are failing with the following error:
process 31778: arguments to dbus_type_is_basic() were incorrect, assertion "dbus_type_is_valid (typecode) || typecode == DBUS_TYPE_INVALID" failed in file dbus-signature.c line 322.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace

When I attempted to make a mapping file for Android gamepads, I quickly discovered that most of the ones that I have here show up as the same device (Broadcom Bluetooth HID), meaning that it was impossible to make mappings on Android, since every device looked the same.
This patch will check for the existence of the getDescriptor function added in Jelly Bean, and use it if it's there. The Android Dashboard says that the majority of Android phones should support this function, and doing it this way will not force us to bump up our API version.

Hi! here's a patch for that with two class loaded regarding API level.
Test both case : before API 11 and after.
I also remove now unused GetSystemServiceFromUIThread() and minor clean-up (haptic warning prototype).

I have occasional crashes here caused by the X11 backend of SDL2. It seems to
be caused by the X11_Pending function trying to add a high number (> 1024)
file descriptor to a fd_set before doing a select on it to avoid busy waiting
on X11 events. This causes a buffer overflow because the file descriptor is
larger (or equal) than the limit FD_SETSIZE.
Attached is a possible workaround patch.
Please also keep in mind that fd_set are also used in following files which
may have similar problems.
src/audio/bsd/SDL_bsdaudio.c
src/audio/paudio/SDL_paudio.c
src/audio/qsa/SDL_qsa_audio.c

I personally experienced this problem while hacking on the python bindings
package for SDL2 [1] (while doing make runtest). But it easier to reproduce in
a smaller, synthetic testcase.

Here's a patch.
It tries to get the hint first. Resizable will allow any orientation. Otherwise it uses width/height window.
setOrientation method is splitted in static and non-static, so that it can be overloaded in a user subclass.
Some artefact observed :
surfaceChanged() can be called twice at the beginning. When the phone starts in portrait and run a landscape application.

I removed all the static variables from SDLActivity.java
Updated all the SDL_android.c jni calls as well
I added a new function to SDL_android.c/ h
void Android_JNI_SeparateEventsHint(const char* c);
This is called by SDL_androidtouch.c so that this TU doesn't need to call any JNI functions.

This patch is wrong: the structure in question has nothing to do with any
gcc version in use. I suggest reverting this adding a conigury check for
it, instead. Something like the following should do it: (configure needs
regenerating.)
This should remain binary compatible with Windows XP, as we dynamically
load anything we need and fall back to DirectSound/WinMM/XAudio2 if not
available.
K_NORMTAB, K_SHIFTTAB, K_ALTTAB, K_ALTSHIFTTAB
In the normal case we'll load all the keymaps from the kernel, but this reduces the size of the SDL library for the fallback case when we can't get to the tty.

I've ran into an issue where I successfully receive SDL_KEY[UP,DOWN] events but not SDL_TEXTINPUT or SDL_TEXTEDITING. In my case the code in SDL_EVDEV_do_text_input() is returning early (on error) prior to calling SDL_SendKeyboardText(). I'm running on the RaspberryPi 3, without X11.
In SDL_EVDEV_do_text_input() there is a condition to check keysyms with a type value below 0xf0, then subtract 0xf0 from type. Without understanding the purpose of this code, I disabled it, recompiled, and I'm getting correct SDL_TEXTINPUT events. I'm going to guess that my hack/fix is going to be problematic in some other environment, but after some initial testing it looks like everything is running fine in my setup.
tvc
I believe this patch should fix it, instead of looping through all the tty's and seemingly selecting the wrong one and corrupting the console I've just made SDL open /dev/tty which is the console attached to the current process anyway.
Rob
When calling ioctl(fd, KDGKBTYPE, &type) in SDL_EVDEV_is_console(), we declare type as an 'int'. This should be a 'char'. The subsequent syscall, and kernel code, only writes the lower byte of the word.
See: http://lxr.free-electrons.com/source/drivers/tty/vt/vt_ioctl.c?v=4.4#L399
ucval = KB_101;
ret = put_user(ucval, (char __user *)arg);
I've observed intermittent behavior related to this, and I can force an error condition by using an int initialized to 0xFFFFFFFF. The resulting ioctl will set type to 0XFFFFFF02, and the conditional return in SDL_EVDEV_is_console() will fail.
Recommend changing to char, or masking off unused bits.

Compiling even a simple SDL2 'hello world' program with gcc -Wstrict-prototypes (GCC 6.2.1) results in warnings like:
/usr/include/SDL2/SDL_gamecontroller.h:143:1: attention : function declaration isn't a prototype [-Wstrict-prototypes]
extern DECLSPEC int SDLCALL SDL_GameControllerNumMappings();
^~~~~~
It seems there is a missing 'void' between the parentheses.

Just moved ibus direct call to SDL_IME_* related functions, and adds fcitx IME support (uses DBus, too),
enable with env: SDL_IM_MODULE=fcitx (ibus still the default one)

I've spent the last few days implementing touchscreen support in core/linux/SDL_evdev.c. It's fairly rudimentary at the moment, as can be seen from the multiple TODO's and FIXME's littered throughout, but I'm mainly submitting this patch for review. I've tested this patch on my Raspberry Pi 2 with the official touchscreen and it works fantastically, reporting all 10 multitouch points. I'm happy to work on this further, the evdev logic also needs a bit of a cleanup I think (I may have included a few changes). But if it's good enough in its current state to be committed then I'm sure there'd be plenty of people pleased, as currently the only other framework/library that supports touchscreens on the Raspberry Pi is Kivy.
Moved this code from winmm into core so both can use it.
DirectSound (at least on Win10) also returns truncated device names, even
though it's handed in as a string pointer and not a static-sized buffer. :/
Win10's 'GamepadAdded' event seems to need to have something registered with it
in order for Xinput-based gamepad detection to work. This 'fix' simply causes
a dummy event-handler to be added for this event, in case an app wants to use
gamepads on Xbox One (most likely).
"UWP" appears to be Microsoft's new name for WinRT/Windows-Store APIs.
This set of changes updates SDL's WinRT backends to support the Win10 flavor
of WinRT. It has been tested on Win10 on a desktop. In theory, it should
also support Win10 on other devices (phone, Xbox One, etc.), however further
patches may be necessary.
This adds:
- a set of MSVC 2015 project files, for use in creating UWP apps
- modifications to various pieces of SDL, in order to compile via MSVC 2015 +
the Win10 API set
- enables SDL_Window resizing and programmatic-fullscreen toggling, when using
the WinRT backend
- WinRT README updates
This change-set fixes a lot of windowing related bugs, especially with
regards to Windows 8.x apps running on Windows 10 (which was the driver for
this work). The primary fixes include:
* listed display modes were wrong, especially when launching apps into a
non-fullscreen space
* reported window flags were often wrong, especially on Windows 10
* fullscreen/windowed mode switches weren't failing (they are not
programmatically possible in Win 8.x apps).
This change has also been tested as buildable + runnable on Win32 + MSVC 2015,
2013, 2012, and 2010. It may fix similar build errors (in XInput code) that
are appearing in MingW builds (on buildbot).
They were not needed internally since the switch to the common EGL backend.
Thanks to the SDL mailing list for pointing out that the functions seem unused.
Sometimes, on removal SDL_EVDEV_udev_callback() gets called with zero udev_class. This in turn seems to be caused the SDL_udev.c:guess_device_class() failing to find the attributes of the parent device.
Apparently this is normal, attributes are not guaranteed to be in place during removal, depending on timing. This lack of attributes causes guess_device_class() to return zero.
This fix mimics the code in linux/SDL_sysjoystick.c:joystick_udev_callback() which effectively has the same fix already in place.
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().
