fbd230bb	2022-05-03T17:51:49	Add support for the Nokia N-Gage (#5597) * Add initial support for the Nokia N-Gage * N-Gage: disable clipping for the time being, issue needs to be resolved later * Move va_copy definition to SDL_internal.h * Move stdlib.h include to SDL_config_ngage.h, much cleaner this way * Remove redundant include, add HAVE_STDLIB_H * Revert "N-Gage: disable clipping for the time being, issue needs to be resolved later" This reverts commit 4f5f0fc36cc7f34fad05e45671dfa7b8dc32fd51. * N-Gage: fix clipping issue by providing proper math functions
d4a01bfe	2022-04-20T14:07:30	os2: SDL_DestroyMutex should ignore NULL mutexes. Every other backend does this, so this should match, now. It's possible this was harmless, but we can avoid the system call and the (likely?) debug message when it fails, though!

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>

5dccffd7	2021-08-23T21:16:58	Allow usage of the new Condition Variable code with Critical Sections Vista and later provide the SleepConditionVariableCS() function for this. Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to SDL_syscond_cv.c which better reflects the implementation of condition variables rather than the implementation of mutexes. Fixes #4051.
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.

f70e1973	2021-02-08T18:31:08	Fix waiting on condition variables with the SRW lock implmentation When SleepConditionVariableSRW() releases the SRW lock internally, it causes our SDL_mutex_srw state to become inconsistent. The lock is unowned yet inside, the owner is still the sleeping thread and more importantly the owner count is still 1. The next time someone acquires the lock, they will bump the owner count from 1 to 2. At that point, the lock is hosed. From the internal lock state, it looks to us like that owner has acquired the lock recursively, even though they have not. When they call SDL_UnlockMutex(), it will see the owner count > 0 and not call ReleaseSRWLockExclusive(). Now when someone calls SDL_CondSignal(), SleepConditionVariableSRW() will start the wakeup process by attempting to re-acquire the SRW lock. This will deadlock because the lock was never released after the other thread had used it. The thread waiting on the condition variable will never be able to wake up, even if the SDL_CondWaitTimeout() function is used and the timeout expires.
265a1cc9	2021-01-05T15:50:02	use WIN_StringToUTF8W instead of WIN_StringToUTF8 where needed (#2) cf. bug #5435. - SDL_wasapi_win32.c (GetWasapiDeviceName): pwszVal is WCHAR* - windows/SDL_sysfilesystem.c (SDL_GetBasePath, SDL_GetPrefPath) - windows/SDL_sysurl.c (SDL_SYS_OpenURL): wurl is WCHAR* - SDL_windowssensor.c (ConnectSensor): bstr_name is WCHAR* - windows/SDL_systhread.c (SDL_SYS_SetupThread): strw is WCHAR*

a19c008a	2020-12-22T17:10:02	use GetModuleHandleW() to retrieve kernel32.dll handle (bug #5390.) SDL_systhread.c and SDL_syslocale.c used to call LoadLibrary() without calling FreeLibrary() later. GetModuleHandleW() should always succeed because GetModuleHandleW() itself is imported from kernel32.dll and we don't need to bother releasing it.
cb361896	2020-12-09T07:16:22	Fixed bug 5235 - All internal sources should include SDL_assert.h Ryan C. Gordon We should really stick this in SDL_internal.h or something so it's always available.
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
a90f0400	2020-10-15T21:37:30	os2: a _lot_ of coding style cleanup, sot that they match the SDL style. also renamed the 'debug' macro to debug_os2: the former was dangerously a common name. the binary (dll) output is precisely the same as before.

222f0268	2020-10-14T23:01:03	os/2: port from SDL2-2.0.4 to SDL2-2.0.5: changes to SDL_os2audio.c, SDL_os2video.c, os2/SDL_systhread.c in order to accomodate SDL2-2.0.5 changes. - audio: WaitDone() is gone, CloseDevice() interface changes. - events / video: DropFile() changes: SDL_DROPBEGIN and SDL_DROPCOMPLETE events, window IDs for drops. - thread: struct SDL_Thread->stacksize
f9af19f5	2020-10-14T23:01:02	os2: updates to SDL_systhread.c: removed lots of garbage. added SDL_PASSED_BEGINTHREAD_ENDTHREAD guard, because the code requires it.
74cfb81d	2020-10-14T23:01:00	os2: add port files for SDL2-2.0.4 from Andrey Vasilkin only geniconv/iconv.h (was from LGPL libiconv) is replaced with a generic minimal iconv.h based on public knowledge.

de866e66	2020-05-26T13:19:29	Include SDL_hint.h.
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.

46bb47cf	2020-03-26T22:14:59	thread: Put all important SDL_CreateThread internal data into SDL_Thread. This avoids the need to malloc something extra, use a semaphore, etc, and fixes Emscripten with pthreads support, which might not spin up a web worker until after SDL_CreateThread returns and thus can't wait on a semaphore at this point in any case. Fixes Bugzilla #5064.
bd5da73a	2020-03-01T12:50:42	Fixed bug 4992 - UWP/WinRT does not set thread priority when using SDL_SetThreadPriority Ethan Lee Attached is a diff that I used to get SetThreadPriority working locally. I still have no idea what the minimum SDK version is since Microsoft never documented it, but it's worth pointing out that they're much more aggressive about using the latest VS and UWP SDK anyway (for example, an updated Xbox is no longer compatible with VS2017, and updates are required to have a network connection of any kind).

816a6e68	2018-04-23T17:10:36	Added support for adjusting thread priorities using Linux RealtimeKit Michael Sartain This is a quick pass at adding Linux RealtimeKit thread priority support to SDL. It allows me to bump the thread priority to high without root privileges or setting any caps, etc. rtkit readme here: http://git.0pointer.net/rtkit.git/tree/README

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.

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.
6d661cab	2017-06-06T13:12:43	windows: Change the default on SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING. It's easier for Visual Studio users that want this information to turn it on or live without it, than it is to explain why every debugger that isn't Visual Studio crashes out here.

This is a bleeding edge API, added to Windows 10 Anniversary Edition (build 1607, specifically). https://msdn.microsoft.com/en-us/library/windows/desktop/mt774976(v=vs.85).aspx Nothing supports this yet, including WinDbg, Visual Studio, minidumps, etc, so we still need to also use the RaiseException hack. But presumably tools will use this API as a more robust and universal way to get thread names sooner or later, so we'll start broadcasting to it now.

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.

Fix waiting on condition variables with the SRW lock implmentation When SleepConditionVariableSRW() releases the SRW lock internally, it causes our SDL_mutex_srw state to become inconsistent. The lock is unowned yet inside, the owner is still the sleeping thread and more importantly the owner count is still 1. The next time someone acquires the lock, they will bump the owner count from 1 to 2. At that point, the lock is hosed. From the internal lock state, it looks to us like that owner has acquired the lock recursively, even though they have not. When they call SDL_UnlockMutex(), it will see the owner count > 0 and not call ReleaseSRWLockExclusive(). Now when someone calls SDL_CondSignal(), SleepConditionVariableSRW() will start the wakeup process by attempting to re-acquire the SRW lock. This will deadlock because the lock was never released after the other thread had used it. The thread waiting on the condition variable will never be able to wake up, even if the SDL_CondWaitTimeout() function is used and the timeout expires.

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.

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.

thread: Don't use SetThreadDescription on WinRT right now. Can't LoadLibrary for it, but not sure if it's actually available there yet.

windows: first shot at naming threads with SetThreadDescription(). This is a bleeding edge API, added to Windows 10 Anniversary Edition (build 1607, specifically). https://msdn.microsoft.com/en-us/library/windows/desktop/mt774976(v=vs.85).aspx Nothing supports this yet, including WinDbg, Visual Studio, minidumps, etc, so we still need to also use the RaiseException hack. But presumably tools will use this API as a more robust and universal way to get thread names sooner or later, so we'll start broadcasting to it now.

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.
