040bd7a9	2020-12-28T00:55:28	Fix udev not detecting ID_INPUT_KEY devices when udev is not running https://bugzilla.libsdl.org/show_bug.cgi?id=5308 The udev code labels devices that are found by this code with ID_INPUT_KEY which in turn gets used by SDL to label the devices as SDL_UDEV_DEVICE_KEYBOARD. This was missing for the code path when udev is not running and as such devices such as the power button of a phone was not detected as keyboard input and no devices were emitted.

It also supports accented input, AltGr keys and Alt Lock combinations. Tested with US accent keys layout and various AltGr layouts.

fdd945f2	2020-11-11T19:14:52	joystick: Use a better heuristic to guess what is a joystick Previously we only checked for at least one button or key and at least the X and Y absolute axes, but this has both false positives and false negatives. Graphics tablets, trackpads and touchscreens all have buttons and absolute X and Y axes, but we don't want to detect those as joysticks. On normal Linux systems ordinary users do not have access to these device nodes, but members of the 'input' group do. Conversely, some game controllers only have digital buttons and no analogue axes (the Nintendo Wiimote is an example), and some have axes and no buttons (steering wheels or flight simulator rudders might not have buttons). Use the more elaborate heuristic factored out from SDL's udev code path to handle these cases. In an ideal world we could use exactly the same heuristic as udev's input_id builtin, but that isn't under a suitable license for inclusion in SDL, so we have to use a parallel implementation of something vaguely similar.

07eae7d6	2020-11-11T08:47:18	Fix process randomly getting killed when SDL_THREAD_PRIORITY_HIGH/TIME_CRITICAL is set When we request realtime priority from rtkit, we have a rttime limit. If we exceed that limit, the kernel will send SIGKILL to the process to terminate it. This isn't something that most high priority processes will want, only processes that selectively opt into SCHED_RR/FIFO through SDL_HINT_THREAD_PRIORITY_POLICY should be subject to this level of scrutiny. This change: * Switches non-apple posix OSs to use SCHED_OTHER instead of SCHED_RR for SDL_THREAD_PRIORITY_HIGH/SDL_THREAD_PRIORITY_TIME_CRITICAL. * Fixes using a hardcoded RLIMIT_RTTIME, instead queries it from rtkit * Only sets RLIMIT_RTTIME for MakeRealtime rtkit requests * Adds a note regarding the possible SIGKILL with SDL_HINT_THREAD_PRIORITY_POLICY * Introduces SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL to allow apps to acquire realtime scheduling policies on Linux
94924f01	2020-11-09T10:11:55	Fix failing to set high priority for threads on Linux desktop. Debugging inside rtkit showed we were failing the RLIMIT_RTTIME check, now that we're asking for realtime and not just high-priority due to a change in SDL. Between that and the DBus code in SDL being wrong in previous changelist I'm not sure how this could have ever worked.

abd58418	2020-05-26T13:19:19	Make some changes to SDL_SetThreadPriority to try and have SDL transparently handle more of the work. 1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority. 2. Add a hint to override SDL's default behavior for scheduler policy. 3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority. 4. Add hint checks in SDL_SetThreadPriority so that #3 can be overridden if desired. 5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API. 6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires. Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.
eadc8693	2020-05-11T14:31:04	Fixed bug 5103 - Port fcitx support to both fcitx 4 & 5 wengxt Due to the new major fcitx version is coming close, the existing code need to be ported to use new Fcitx dbus interface. The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.
ba95fa61	2020-04-08T08:42:09	Revert "Fix incorrectly terminated MakeThreadHighPriority dbus message" The first terminator is for input parameters. The second terminator was for the output parameters. If an error occurs when calling MakeThreadHighPriority(), e.g. a bad thread id, then the reply from connection_send_with_reply_and_block() will be null.
f4a56d7e	2020-03-30T14:26:15	Enable thread-safety features in libdbus There are multiple SDL APIs that internally sink into dbus calls, e.g. battery status, thread priority. If those calls happen in different threads simultaneously it can result in dbus crashes. To abide by dbus's multithreading guidelines we must call dbus_threads_init_default() to enable dbus's internal locking mechanisms: https://dbus.freedesktop.org/doc/api/html/group__DBusThreads.html#gac7b8a7001befc3eaa8c6b043151008dc Additionally, access to a DBusMessage must be synchronized between threads. SDL was already abiding that guideline as the DBusMessage structs aren't shared. The following email from the dbus mailing list hints that arbitrating access to the DBusConnection on the SDL may also be required: https://lists.freedesktop.org/archives/dbus/2017-September/017306.html

Instead, guard SDL_dbus.h based on the autoconf variable HAVE_DBUS_DBUS_H Additionally, fix one of the rtkit comments. CAP_SYS_NICE isn't required to achieve high priority. But there is some scheduler config that rtkit needs the app to setup.
aaec90e5	2019-09-06T08:42:54	Fixed bug 4789 - Linux accelerometers no longer available as joysticks Daniel Drake A long time ago, it was possible to play neverball on Linux using the accelerometer found in HP laptops. The kernel exposes the accelerometer as a joystick (/dev/input/jsX) as well as an evdev device (/dev/input/eventX). I guess it worked fine when SDL was using the js interface, but then stopped working here: http://hg.libsdl.org/SDL/rev/fdaeea9e7567 Looking at current code which uses udev to discover joysticks, it looks for the udev tag ID_INPUT_JOYSTICK. However udev's internal input_id logic specifically tags accelerometers as ID_INPUT_ACCELEROMETER and nothing else. This looks like a good fit for SDL_HINT_ACCELEROMETER_AS_JOYSTICK.

67bb882e	2019-07-03T15:57:55	Fixed bug 4707 - SDL_SetRelativeMouseMode fails on Vivante Cameron Gutman The bugfix in https://hg.libsdl.org/SDL/rev/ca9417a52f18 caused SDL_SetRelativeMouseMode() to begin failing on Vivante (Steam Link). Even though Vivante doesn't have a SetRelativeMouseMode() or WarpMouse() function, it's in relative mode already (because it uses evdev) so the function was actually working as intended. I think providing a no-op SetRelativeMouseMode() function for Vivante is a reasonable fix. Since it's already getting relative events through evdev, it really is a no-op to "enter relative mode". In fact, this is probably the right thing to do for all backends that use evdev (vivante, raspberry, and kmsdrm). Raspberry and kmsdrm both have WarpMouse() implementations so SDL_SetRelativeMouseMode() isn't failing there, but it still seems to make sense not to have to do the fake warping if they're evdev-based anyway.

f59b0056	2018-08-07T16:56:46	evdev: On sudden termination, make sure keyboard isn't lost (thanks, Tadek!) "In release 2.0.6, when Linux evdev keyboard support has been moved to a separate source file, a feature was added to disable normal keyboard event processing to prevent "spilling" keystrokes to background virtual console. This feature has one unpleasant side effect: if application fails to call `SDL_Exit` before termination or crashes with fatal signal, console is left in unusable state with keyboard not working and no possibility to switch virtual console. If user has a chance, he can login remotely and restore keyboard with `kbd_mode`, otherwise the only option is to reboot the machine. This patch fixes that problem by intercepting fatal signals (with `sigaction`) and process termination (with `atexit`), to restore keyboard state, if it wasn't properly restored with `SDL_Exit`. The function registered with `atexit` also restores original signal handlers, to prevent leaving invalid handlers after SDL library is unloaded, if it was loaded dynamically with `dlopen`. No signal handlers or `atexit` function are installed if SDL boolean hint `SDL_HINT_NO_SIGNAL_HANDLERS` is `SDL_TRUE`. Additionally, if environment variable `SDL_INPUT_LINUX_KEEP_KBD` exists, keyboard initialization function completely skips disabling keyboard. This can be useful for debugging." Fixes Bugzilla #4193.

9924a8e3	2018-06-14T00:51:45	Fixed bug 4094 - No SDL_TEXTEDITING after pressing Alt key on Raspberry Pi Linux 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...

714085d3	2018-02-13T08:07:52	Fixed bug 3950 - Don't always call dbus_shutdown in SDL_DBus Alexander Larsson 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.

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.

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.

49292705	2017-01-08T20:03:18	Fixed bug 3545 - SDL_EVDEV_do_text_input() may be too eager to find error cases Rob 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.

41be9756	2017-01-05T23:26:13	Fixed bug 3546 - SDL_EVDEV_is_console() uses type of wrong size when calling ioctl 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.

This was missing for the code path when udev is not running and as such devices such as the power button of a phone was not detected as keyboard input and no devices were emitted.

joystick: Use a better heuristic to guess what is a joystick Previously we only checked for at least one button or key and at least the X and Y absolute axes, but this has both false positives and false negatives. Graphics tablets, trackpads and touchscreens all have buttons and absolute X and Y axes, but we don't want to detect those as joysticks. On normal Linux systems ordinary users do not have access to these device nodes, but members of the 'input' group do. Conversely, some game controllers only have digital buttons and no analogue axes (the Nintendo Wiimote is an example), and some have axes and no buttons (steering wheels or flight simulator rudders might not have buttons). Use the more elaborate heuristic factored out from SDL's udev code path to handle these cases. In an ideal world we could use exactly the same heuristic as udev's input_id builtin, but that isn't under a suitable license for inclusion in SDL, so we have to use a parallel implementation of something vaguely similar.

Fix process randomly getting killed when SDL_THREAD_PRIORITY_HIGH/TIME_CRITICAL is set When we request realtime priority from rtkit, we have a rttime limit. If we exceed that limit, the kernel will send SIGKILL to the process to terminate it. This isn't something that most high priority processes will want, only processes that selectively opt into SCHED_RR/FIFO through SDL_HINT_THREAD_PRIORITY_POLICY should be subject to this level of scrutiny. This change: * Switches non-apple posix OSs to use SCHED_OTHER instead of SCHED_RR for SDL_THREAD_PRIORITY_HIGH/SDL_THREAD_PRIORITY_TIME_CRITICAL. * Fixes using a hardcoded RLIMIT_RTTIME, instead queries it from rtkit * Only sets RLIMIT_RTTIME for MakeRealtime rtkit requests * Adds a note regarding the possible SIGKILL with SDL_HINT_THREAD_PRIORITY_POLICY * Introduces SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL to allow apps to acquire realtime scheduling policies on Linux

Make some changes to SDL_SetThreadPriority to try and have SDL transparently handle more of the work. 1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority. 2. Add a hint to override SDL's default behavior for scheduler policy. 3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority. 4. Add hint checks in SDL_SetThreadPriority so that #3 can be overridden if desired. 5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API. 6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires. Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.

The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.

Enable thread-safety features in libdbus There are multiple SDL APIs that internally sink into dbus calls, e.g. battery status, thread priority. If those calls happen in different threads simultaneously it can result in dbus crashes. To abide by dbus's multithreading guidelines we must call dbus_threads_init_default() to enable dbus's internal locking mechanisms: https://dbus.freedesktop.org/doc/api/html/group__DBusThreads.html#gac7b8a7001befc3eaa8c6b043151008dc Additionally, access to a DBusMessage must be synchronized between threads. SDL was already abiding that guideline as the DBusMessage structs aren't shared. The following email from the dbus mailing list hints that arbitrating access to the DBusConnection on the SDL may also be required: https://lists.freedesktop.org/archives/dbus/2017-September/017306.html

Fixed bug 4789 - Linux accelerometers no longer available as joysticks Daniel Drake A long time ago, it was possible to play neverball on Linux using the accelerometer found in HP laptops. The kernel exposes the accelerometer as a joystick (/dev/input/jsX) as well as an evdev device (/dev/input/eventX). I guess it worked fine when SDL was using the js interface, but then stopped working here: http://hg.libsdl.org/SDL/rev/fdaeea9e7567 Looking at current code which uses udev to discover joysticks, it looks for the udev tag ID_INPUT_JOYSTICK. However udev's internal input_id logic specifically tags accelerometers as ID_INPUT_ACCELEROMETER and nothing else. This looks like a good fit for SDL_HINT_ACCELEROMETER_AS_JOYSTICK.

Fixed bug 4707 - SDL_SetRelativeMouseMode fails on Vivante Cameron Gutman The bugfix in https://hg.libsdl.org/SDL/rev/ca9417a52f18 caused SDL_SetRelativeMouseMode() to begin failing on Vivante (Steam Link). Even though Vivante doesn't have a SetRelativeMouseMode() or WarpMouse() function, it's in relative mode already (because it uses evdev) so the function was actually working as intended. I think providing a no-op SetRelativeMouseMode() function for Vivante is a reasonable fix. Since it's already getting relative events through evdev, it really is a no-op to "enter relative mode". In fact, this is probably the right thing to do for all backends that use evdev (vivante, raspberry, and kmsdrm). Raspberry and kmsdrm both have WarpMouse() implementations so SDL_SetRelativeMouseMode() isn't failing there, but it still seems to make sense not to have to do the fake warping if they're evdev-based anyway.

Fixed bug 4347 - Keyboard LEDs don't work on linux console Rainer Sabelka When using SLD2 on a Linux console with the KMS/DRM video backend and Linux evdev keyboard support, the caps lock, scroll lock, and num lock leds do not work. The attached patch adds ioctls for setting the LED state in SDL_evdev_kbd.c

Add and update include guards Include guards in most changed files were missing, I added them keeping the same style as other SDL files. In some cases I moved the include guards around to be the first thing the header has to take advantage of any possible improvements compiler may have for inclusion guards.

evdev: On sudden termination, make sure keyboard isn't lost (thanks, Tadek!) "In release 2.0.6, when Linux evdev keyboard support has been moved to a separate source file, a feature was added to disable normal keyboard event processing to prevent "spilling" keystrokes to background virtual console. This feature has one unpleasant side effect: if application fails to call `SDL_Exit` before termination or crashes with fatal signal, console is left in unusable state with keyboard not working and no possibility to switch virtual console. If user has a chance, he can login remotely and restore keyboard with `kbd_mode`, otherwise the only option is to reboot the machine. This patch fixes that problem by intercepting fatal signals (with `sigaction`) and process termination (with `atexit`), to restore keyboard state, if it wasn't properly restored with `SDL_Exit`. The function registered with `atexit` also restores original signal handlers, to prevent leaving invalid handlers after SDL library is unloaded, if it was loaded dynamically with `dlopen`. No signal handlers or `atexit` function are installed if SDL boolean hint `SDL_HINT_NO_SIGNAL_HANDLERS` is `SDL_TRUE`. Additionally, if environment variable `SDL_INPUT_LINUX_KEEP_KBD` exists, keyboard initialization function completely skips disabling keyboard. This can be useful for debugging." Fixes Bugzilla #4193.

Fixed bug 4094 - No SDL_TEXTEDITING after pressing Alt key on Raspberry Pi Linux 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...

Fixed bug 3950 - Don't always call dbus_shutdown in SDL_DBus Alexander Larsson 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.

Fixed bug 2330 - Debian bug report: SDL2 X11 driver buffer overflow with large X11 file descriptor manuel.montezelo Original bug report (note that it was against 2.0.0, it might have been fixed in between): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733015 -------------------------------------------------------- Package: libsdl2-2.0-0 Version: 2.0.0+dfsg1-3 Severity: normal Tags: patch 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 src/audio/sun/SDL_sunaudio.c src/joystick/linux/SDL_sysjoystick.c -------------------------------------------------------- On Tuesday 24 December 2013 00:43:13 Sven Eckelmann wrote: > I have occasional crashes here caused by the X11 backend of SDL2.

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.

We only need the first few keymaps corresponding to the following constants: 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.

Fixed bug 3545 - SDL_EVDEV_do_text_input() may be too eager to find error cases Rob 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.

Fixed bug 3546 - SDL_EVDEV_is_console() uses type of wrong size when calling ioctl 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.
