e061a92dc9 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.

d226594fcc Workaround for bug 3049 - SDL_Init(SDL_INIT_VIDEO) - XDM authorization key matches an existing client!
malferit

Hello, I began a little program with SDL2 on Linux in C, and when I call SDL_Init(SDL_INIT_VIDEO) I get an error and this is printed in the console:

XDM authorization key matches an existing client!

I searched through Internet, and found that some people suggest to run 'xhost +' or to specify this in /etc/X11/xdm/xdm-config:

DisplayManager*authName:        MIT-MAGIC-COOKIE-1

I don't think an end user needs to know that...

But what bothered me is that first I started this little program in Pascal using the Freepascal compiler and it works. In freepascal you only use some thin header bindings in Pascal and then it links with the dynamic SDL library, so I don't understood why it worked with Freepascal and not in C.

I run ldd to the two generated applications:

Application in C:

	linux-gate.so.1 (0xffffe000)
	libSDL2-2.0.so.0 => /usr/lib/libSDL2-2.0.so.0 (0xb76ac000)
	libpthread.so.0 => /lib/libpthread.so.0 (0xb766e000)
	libc.so.6 => /lib/libc.so.6 (0xb74e2000)
	libm.so.6 => /lib/libm.so.6 (0xb74a0000)
	libdl.so.2 => /lib/libdl.so.2 (0xb749a000)
	librt.so.1 => /lib/librt.so.1 (0xb7491000)
	/lib/ld-linux.so.2 (0xb77b3000)

Application compiled with Freepascal:

	linux-gate.so.1 (0xffffe000)
	libSDL2-2.0.so.0 => /usr/lib/libSDL2-2.0.so.0 (0xb762a000)
	libX11.so.6 => /usr/lib/libX11.so.6 (0xb74f3000)
	libc.so.6 => /lib/libc.so.6 (0xb7367000)
	libm.so.6 => /lib/libm.so.6 (0xb7325000)
	libdl.so.2 => /lib/libdl.so.2 (0xb731f000)
	libpthread.so.0 => /lib/libpthread.so.0 (0xb7305000)
	librt.so.1 => /lib/librt.so.1 (0xb72fc000)
	libxcb.so.1 => /usr/lib/libxcb.so.1 (0xb72dc000)
	libXau.so.6 => /usr/lib/libXau.so.6 (0xb72d9000)
	libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb72d3000)
	/lib/ld-linux.so.2 (0xb7755000)

It seems that Freepascal is linking with libX11, libxcb, libXau and libXdmcp .

Linking my C application with libxcb solved the problem (linking with libXau and/or libXdmcp without libxcb didn't work). Linking with X11 links all the other libraries and works as well.

So I fill this bug report mainly to let you know about this. I don't know if it is a problem that can be solved on the libSDL side or not, but at least I hope it will help.

Hi, some tests:

1. Disabled XDM. Login in console and running 'startx'. The program works without having to link with X11.

2. Enabled XDM. Added 'DisplayManager*authName: MIT-MAGIC-COOKIE-1' to /etc/X11/xdm/xdm-config.The program works without having to link with X11.

3. Enabled XDM without 'DisplayManager*authName: MIT-MAGIC-COOKIE-1' in /etc/X11/xdm/xdm-config . I get the authentication error unless I link with X11.

2ffd6d0208 x11: Make a separate unmapped window to own clipboard selections.
Now the clipboard isn't lost if you destroy a specific SDL_Window, as it
works on other platforms. You will still lose the clipboard data on
SDL_Quit() or process termination, but that's X11 for you; run a
Clipboard Manager daemon.

Fixes Bugzilla #3222.
Fixes Bugzilla #3718.

cf31ea1478 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.

02f49fdb53 x11: Deal with window borders better.
- Cache the _NET_FRAME_EXTENTS data locally, so we don't have to query
the X server for them (instead, we update our cached data when PropertyNotify
events alert us to a change).

- Use our cached extents for X11_GetWindowBordersSize(), so it's a fast call.

- Window position was meant to refer to the client area, not the window
decorations, so adjust appropriately when getting/setting the position.

This is for corner cases where a multi-window app is activated and wants to
make a decision about where focus should go.

0e45984fa0 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().
