43ddc59f	2021-11-02T16:56:14	Export SDL_LinuxSetThreadPriorityAndPolicy() function (#4877) It's marked as being a public symbol internally, however, it was missing from the header files and not visible in the shared library. This adds it to the necessary headers and to the DynAPI list to expose it for use by applications. Co-authored-by: Frank Praznik <frank.praznik@oh.rr.com>
77c8d111	2021-08-10T20:55:50	configuration updates for dlopen: - cmake, configure (CheckDLOPEN): --enable-sdl-dlopen is now history.. detach the dl api discovery from SDL_LOADSO_DLOPEN functionality. define HAVE_DLOPEN. also define DYNAPI_NEEDS_DLOPEN (CheckDLOPEN is called only for relevant platforms.) - update SDL_config.in and SDL_config.cmake accordingly. - SDL_dynapi.h: set SDL_DYNAMIC_API to 0 if DYNAPI_NEEDS_DLOPEN is defined, but HAVE_DLOPEN is not. - pthread/SDL_systhread.c: conditionalize dl api use to HAVE_DLOPEN - SDL_x11opengl.c, SDL_DirectFB_opengl.c, SDL_naclopengles.c: rely on HAVE_DLOPEN, not SDL_LOADSO_DLOPEN. - SDL_config_android.h, SDL_config_iphoneos.h, SDL_config_macosx.h, SDL_config_pandora.h, and SDL_config_wiz.h: define HAVE_DLOPEN.

0500c044	2020-11-12T07:53:05	Fix SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL also applying to HIGH priorities As the name suggests, the hint should only apply to SDL_THREAD_PRIORITY_TIME_CRITICAL The resulting priorities for my current distro result in these values: \| High \| Time Critical Hint \|--------------\|----------------- 0 \| P=10 N=-10 \| P=5 N=-15 1 \| P=10 N=-10 \| P=-21 N=0
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

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.

f9f45d0b	2018-02-25T19:51:34	Fixed bug 4097 - Segmentation fault by SDL_CreateThreadWithStackSize Dongsun Kim Normal case 1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread. 2. [thread 1] If successful, it calls SDL_SemWait. 3. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost. 4. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free. Crash case (Segmentation fault) 1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread. 2. [thread 1] If successful, it calls SDL_SemWait. --> Error return due to SIGNAL(SYSTEM or Real Time) at sem_wait(pthread). 3. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free. 4. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost. --> Segmentation fault at strlen or sem_post.
75a58303	2018-02-17T23:57:57	pthread: fix error code checks (thanks, Andreas!). Most pthread functions return 0 on success and non-zero on error, but those errors might be positive or negative, so checking for return values in the Unix style, where errors are less than zero, is a bug. Fixes Bugzilla #4039.
40b27fd5	2018-02-12T17:00:00	revert the recent typecast assignment changes (see bug #4079) also change the void* typedefs for the two vulkan function pointers added in vulkan_internal.h into generic function pointer typedefs.

7229397c	2017-08-11T21:47:31	Fixed bug 3258 - SDL_TryLockMutex blocks for pthreads with FAKE_RECURSIVE_MUTEX Ian Abbott I just spotted what I think is a bug in "src/thread/pthread/SDL_sysmutex.c" in the SDL_TryLockMutex function when FAKE_RECURSIVE_MUTEX is defined (for an implementation of Pthreads with no recursive mutex support). It calls pthread_mutex_lock instead of pthread_mutex_trylock, so it will block until the mutex is available instead of returning SDL_MUTEX_TIMEDOUT if it cannot lock the mutex immediately.

83cb2b63	2016-10-14T06:57:55	Fixed bug 2758 - Android issues with NDK r10c and API-21 Sylvain After a long time, I found out more clearly what was going wrong. The native libraries should be built with a "APP_PLATFORM" as low as possible. Ideally, APP_PLATFORM should be equals to the minSdkVersion of the AndroidManifest.xml So that the application never runs on a lower APP_PLATFORM than it has been built for. An additional good patch would be to write explicitly in "jni/Application.mk": APP_PLATFORM=android-10 (If no APP_PLATFORM is set, the "targetSdkVersion" of the AndroidManifest.xml is applied as an APP_PLATFORM to the native libraries. And currently, this is bad, because targetSdkVersion is 12, whereas minSdkLevel is 10. And in fact, there is a warning from ndk: "Android NDK: WARNING: APP_PLATFORM android-12 is larger than android:minSdkVersion 10 in ./AndroidManifest.xml".) to precise what happened in the initial reported test-case: Let say the "c" code contains a call to "srand()". with APP_PLATFORM=android-21, libSDL2.so contains a undef reference to "srand()". with APP_PLATFORM=android-10, libSDL2.so contains a undef reference to "srand48()". but srand() is missing on devices with APP_PLATFORM=android-10 (it was in fact replaced by srand48()). So, if you build for android-21 (where srand() is available), you will really have a call to "srand()" and it will fail on android-10. That was the issue. The path tried to fix this by in fact always calling srand48(). SDL patches that were applied are beneficial anyway, there are implicitly allowing they backward compatibility of using android-21 on a android-10 platform. It can be helpful in case you want to target a higher APP_PLATFORM than minSdkVersion to have potentially access to more functions. Eg you want to have access to GLES3 functions (or other) of "android-21". But, if dlopen() fails (on android-10), you do a fall-back to GLES2.

98986f39	2015-08-15T21:21:29	Removed not needed call to pthread_attr_getstacksize() for SDL_CreateThread().
0e45984f	2015-06-21T17:33:46	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().
1a348aac	2015-06-17T21:05:25	Android: Fixed two warnings.
45989035	2015-06-17T00:07:45	Partial fix for bug 2758 - Android issues with NDK r10c and API-21 Sylvain When using API 21 and running on an old device (android < 5.0 ?) some function are missing. functions are (at least) : signal, sigemptyset, atof, stpcpy (strcat and strcpy), srand, rand. Very few modifications on SDL to get this working : on SDL ====== Undefine android configuration : HAVE_SIGNAL HAVE_SIGACTION HAVE_ATOF In "SDL_systrhead.c", comment out the few block of lines with "sigemptyset". Android.mk: remove the compilation of "test" directory because it contains a few rand/srand calls Also, there are more discussions about this in internet : https://groups.google.com/forum/#!topic/android-ndk/RjO9WmG9pfE http://stackoverflow.com/questions/25475055/android-ndk-load-library-cannot-locate-srand

a8fa7bd1	2015-05-26T21:13:27	Added a hint to specify new thread stack size (thanks, Gabriel!). Fixes Bugzilla #2019. (we'll do a better fix when we break the API in SDL 2.1.)

b72938c8	2015-04-20T12:22:44	Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.
fe6c797c	2015-04-10T23:30:31	Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
b88ca1b4	2015-02-10T16:28:56	the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
b48e54aa	2015-01-26T22:00:29	Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
70438be2	2014-12-03T10:55:23	WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!
7ed41da0	2014-11-28T04:37:50	Fixed bug 2411 - Even if built with --enable-clock_gettime, SDL2 still calls gettimeofday() Ben Swick Makes SDL_syscond.c and SDL_syssem.c use clock_gettime(CLOCK_REALTIME) when HAVE_CLOCK_GETTIME is defined.

8d6e03f3	2013-11-14T00:52:39	Added SDL_DetachThread() API.
7550ddcc	2013-11-13T22:35:26	Started BeOS removal: merged BeOS thread and pthread code. Haiku uses most of the standard pthread API, with a few #ifdefs where we still need to fallback onto the old BeOS APIs. BeOS, however, does not support pthreads (or maybe doesn't support it well), so I'm unplugging support for the platform with this changeset. Be Inc went out of business in 2001.
f5fa492e	2013-10-20T20:42:55	Added a macro SDL_TICKS_PASSED() to correctly compare two 32-bit tick values. Went through the code and used the macro and fixed a couple places that were using incorrect timestamp comparisons.
10ffa28a	2013-09-06T20:45:08	Fixed time comparison and explicitly delay 1 ms instead of an arbitrary scheduled time.
eec4710c	2013-08-29T14:03:44	Fixes bug #2074 - Thanks Sylvain! SDL_syssem.c:159 comparison of unsigned expression >= 0 is always true Solved by comparing unsigneds directly SDL_systimer.c:164: warning: control may reach end of Compile Solved by returning the default value if all else fails. SDL_androidgl.c:41:1: warning: type specifier missing, defaults to 'int' SDL_androidgl.c:47:1: warning: control reaches end of non-void function Solved by adding void return type to the function implementation
dad42067	2013-08-12T11:13:50	Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
1ad936eb	2013-08-11T19:56:43	Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.

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

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.

Fixes Bugzilla #5064.

Fixed bug 3258 - SDL_TryLockMutex blocks for pthreads with FAKE_RECURSIVE_MUTEX Ian Abbott I just spotted what I think is a bug in "src/thread/pthread/SDL_sysmutex.c" in the SDL_TryLockMutex function when FAKE_RECURSIVE_MUTEX is defined (for an implementation of Pthreads with no recursive mutex support). It calls pthread_mutex_lock instead of pthread_mutex_trylock, so it will block until the mutex is available instead of returning SDL_MUTEX_TIMEDOUT if it cannot lock the mutex immediately.

Fixed bug 2758 - Android issues with NDK r10c and API-21 Sylvain After a long time, I found out more clearly what was going wrong. The native libraries should be built with a "APP_PLATFORM" as low as possible. Ideally, APP_PLATFORM should be equals to the minSdkVersion of the AndroidManifest.xml So that the application never runs on a lower APP_PLATFORM than it has been built for. An additional good patch would be to write explicitly in "jni/Application.mk": APP_PLATFORM=android-10 (If no APP_PLATFORM is set, the "targetSdkVersion" of the AndroidManifest.xml is applied as an APP_PLATFORM to the native libraries. And currently, this is bad, because targetSdkVersion is 12, whereas minSdkLevel is 10. And in fact, there is a warning from ndk: "Android NDK: WARNING: APP_PLATFORM android-12 is larger than android:minSdkVersion 10 in ./AndroidManifest.xml".) to precise what happened in the initial reported test-case: Let say the "c" code contains a call to "srand()". with APP_PLATFORM=android-21, libSDL2.so contains a undef reference to "srand()". with APP_PLATFORM=android-10, libSDL2.so contains a undef reference to "srand48()". but srand() is missing on devices with APP_PLATFORM=android-10 (it was in fact replaced by srand48()). So, if you build for android-21 (where srand() is available), you will really have a call to "srand()" and it will fail on android-10. That was the issue. The path tried to fix this by in fact always calling srand48(). SDL patches that were applied are beneficial anyway, there are implicitly allowing they backward compatibility of using android-21 on a android-10 platform. It can be helpful in case you want to target a higher APP_PLATFORM than minSdkVersion to have potentially access to more functions. Eg you want to have access to GLES3 functions (or other) of "android-21". But, if dlopen() fails (on android-10), you do a fall-back to GLES2.

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().

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
