Ryan C. Gordon 2379c528 2021-10-25T11:04:42 os/2: Don't try to be clever with the 32-bit GetTicks fallback.
Ryan C. Gordon cca79d32 2021-10-23T15:30:20 android: Patched SDL_GetTicks64() to compile.
Ryan C. Gordon affb183e 2021-10-23T15:20:32 unix: Fixed SDL_GetTicks64 function signature.
Ryan C. Gordon 99c9727d 2021-10-23T15:00:31 timer: Added SDL_GetTicks64(), for a timer that doesn't wrap every ~49 days. Note that this removes the timeGetTime() fallback on Windows; it is a 32-bit counter and SDL2 should never choose to use it, as it only is needed if QueryPerformanceCounter() isn't available, and QPC is _always_ available on Windows XP and later. OS/2 has a similar situation, but since it isn't clear to me that similar promises can be made about DosTmrQueryTime() even in modern times, I decided to leave the fallback in, with some heroic measures added to try to provide a true 64-bit tick counter despite the 49-day wraparound. That approach can migrate to Windows too, if we discover some truly broken install that doesn't have QPC and still depends on timeGetTime(). Fixes #4870.

Sam Lantinga 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.
Ozkan Sezer 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.
Ozkan Sezer 1d9cf23e 2020-10-14T23:01:05 os2: updated copyright dates for 2020. header guard fixes.
Ozkan Sezer 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.

Micha? Janiszewski 91820998 2018-10-28T21:36:48 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.

Sam Lantinga de91b124 2017-08-14T06:28:21 Fixed bug 3745 - specify SDLCALL as the calling convention for API callbacks Patches contributed by Ozkan Sezer
Sam Lantinga 72ab2588 2017-08-13T21:48:40 Fixed bug 2764 - Timer is not rescheduled with the returned interval afwlehmann Sorry for re-opening, but it turns out that the current interval is indeed not updated. I've just checked the source code of the 2.0.3 release again: 163 if (current->canceled) { 164 interval = 0; 165 } else { 166 interval = current->callback(current->interval, current->param); 167 } 168 169 if (interval > 0) { 170 /* Reschedule this timer */ 171 current->interval = interval; // <-- this line is missing 172 current->scheduled = tick + interval; 173 SDL_AddTimerInternal(data, current); 174 } else { According to the documentation: "The callback function is passed the current timer interval and the user supplied parameter from the SDL_AddTimer() call and returns the next timer interval. If the returned value from the callback is 0, the timer is canceled." If I understand the text correctly, then the current interval should in fact be updated according to the returned value. Otherwise there would be a discrepancy between the next time for which the timer is actually re-scheduled and the value that's passed to the callback once the timer fires again. This could be fixed by adding line #171.
Sam Lantinga ca5c3048 2017-08-13T21:06:52 Fixed bug 3744 - missing SDLCALL in several functions Ozkan Sezer The attached patch adds missing SDLCALL to several functions, so that they properly match the headers as intended.
Philipp Wiesemann 84aeab17 2017-07-29T23:00:14 haiku: Changed header paths to be more compatible.

Sam Lantinga 57d01d7d 2016-11-13T22:57:41 Patch from Sylvain to fix clang warnings
Philipp Wiesemann f31ce3fb 2016-10-16T22:47:37 Windows: Fixed not removing the always added hint callback on quit. This was no real problem because SDL_Quit() also calls SDL_ClearHints().
Ryan C. Gordon c61675dc 2016-04-12T16:45:10 threads: Move SDL's own thread creation to a new internal API. This allows us to set an explicit stack size (overriding the system default and the global hint an app might have set), and remove all the macro salsa for dealing with _beginthreadex and such, as internal threads always set those to NULL anyhow. I've taken some guesses on reasonable (and tiny!) stack sizes for our internal threads, but some of these might turn out to be too small in practice and need an increase. Most of them are simple functions, though.
Alex Szpakowski 33af421d 2016-02-14T21:17:25 Windows: make sure SDL_TicksInit has been called before calling Sleep(ms) in SDL_Delay. This ensures the Windows system timer resolution is properly set before Sleep is called.
Ryan C. Gordon fa8c83c1 2016-01-03T06:50:50 Remove almost all instances of "volatile" keyword. As Tiffany pointed out in Bugzilla, volatile is not useful for thread safety: https://software.intel.com/en-us/blogs/2007/11/30/volatile-almost-useless-for-multi-threaded-programming/ Some of these volatiles didn't need to be, some were otherwise protected by spinlocks or mutexes, and some got moved over to SDL_atomic_t data, etc. Fixes Bugzilla #3220.
Sam Lantinga 42065e78 2016-01-02T10:10:34 Updated copyright to 2016
Philipp Wiesemann 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().
Sam Lantinga 903df4af 2015-06-19T23:49:00 Use CLOCK_MONOTONIC_RAW, if available, which is not subject to adjustment by NTP
Sam Lantinga 2c4a6ea0 2015-05-26T06:27:46 Updated the copyright year to 2015
Ryan C. Gordon 69f6f646 2015-04-20T13:43:24 Cleaned up the macro salsa in the Windows timer code. - Removed USE_GETTICKCOUNT code; it's never used now. - Reduced the number of preprocessor checks for WinRT. - Renamed timeSetPeriod() so it doesn't look like a Win32 API call.
Ryan C. Gordon 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.
Alex Szpakowski fe6c797c 2015-04-10T23:30:31 Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
Edward Rudd 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
Philipp Wiesemann 86f87bf7 2015-01-31T22:45:54 Added missing guards in implementation for PSP. Thanks to Martin Gerhardy for pointing this out.
Philipp Wiesemann d036ad84 2015-01-31T22:43:05 Added missing include statements in implementation for PSP. SDL_internal.h should be included to support dynamic API and fix warnings.
Philipp Wiesemann 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.
David Ludwig 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!
Philipp Wiesemann 9c398852 2014-11-22T22:20:40 Corrected header file documentation comment.
David Ludwig e6cca5e9 2014-11-15T10:12:36 WinRT: build fix for Visual C++ 2013 Update 4 Visual C++ 2013 Update 4 re-introduced the Sleep() function to WinRT apps (for code that targets Windows 8.1 and Windows Phone 8.1). This led to a build error, as SDL was defining it's own Sleep() function (to make up for the lack of a public Sleep() function). The fix makes sure that SDL's custom Sleep() function is only used when Windows' Sleep() is not available. Many thanks go out to Sergiu Marian Gaina for the fix!
Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam
Sam Lantinga 7187b74c 2014-07-07T11:00:25 Fixed compiler warnings on iOS

David Ludwig 3dcb451f 2014-04-09T21:29:19 Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.
Sam Lantinga 1367bf87 2014-03-09T11:36:47 Integrated David Ludwig's support for Windows RT
Sam Lantinga 05c23063 2014-03-09T11:06:11 Fixed line endings on WinRT source code
Sam Lantinga e663b4eb 2014-03-01T09:50:52 Fixed bug 2423 - timeBeginPeriod & timeEndPeriod mismatch Coriiander In src\timer\windows\SDL_systimer.c there is an error with regards to timeBeginPeriod and timeEndPeriod. These functions typically get called when no high resolution timer is available, and GetTickCount is not used. According to MSDN (link: http://msdn.microsoft.com/en-us/library/windows/desktop/dd757624(v=vs.85).aspx), for every call to timeBeginPeriod a subsequent call to timeEndPeriod is required. While SDL is currently doing this, it fails to call timeEndPeriod when cleaning up/shutting down SDL. Please note that these functions affect things on a system level. Failing to call timeEndPeriod, disables applications for using WINMM-timers after usage&shutdown of SDL, as effectively they the mechanism is now broken. Solution: Ensure this code gets called when shutting down the timer subsystem: #ifndef USE_GETTICKCOUNT if (!hires_timer_available) { timeSetPeriod(0); } #endif
Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Ryan C. Gordon 090327e7 2013-12-09T16:03:18 Implemented the Dynamic API magic.
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
David Ludwig 46740a5a 2013-11-28T22:09:21 WinRT: merged with latest SDL 2.x/HG code SDL 2.x recently accepted patches to enable OpenGL ES 2 support via Google's ANGLE library. The thought is to try to eventually merge SDL/WinRT's OpenGL code with SDL-official's.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
Ryan C. Gordon 00003e8c 2013-11-14T11:51:24 Renamed things named after BeOS to be named after Haiku instead.
David Ludwig 69c5d21d 2013-10-27T21:26:46 WinRT: merged with SDL 2.0.1 codebase
Gabriel Jacobo 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
Gabriel Jacobo 2490166d 2013-08-21T10:12:16 Fixes for -Wdeclaration-after-statement
Ryan C. Gordon 7e3b7dbc 2013-08-17T20:46:34 Patched to compile with Visual Studio.
Sam Lantinga d7817f42 2013-08-17T17:04:14 Fixed for consistency with the other platforms
Edward Rudd e187810e 2013-08-17T18:07:29 auto init the ticks if the GetTicks and the like methods are called before SDL_Init().. This prevents annoying game bugs such as caching SDL_GetPerformanceFrequency in a static initializer
David Ludwig d41fdc94 2013-08-13T20:09:52 WinRT: build fixes and additional WinRT-related integrations with SDL 2.0.0
Gabriel Jacobo 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.
Sam Lantinga 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.
