b5ea3c6d	2017-08-11T21:30:06	Fixed bug 3284 - minor correction for SDL_setenv on _WIN32__ platform Coriiander Here is a minor correction for a non-breaking mistake in SDL_setenv for __WIN32__ platform. See below for details. FILE: "SDL/src/stdlib/SDL_getenv.c" FUNCTION: (__WIN32__ platform) int SDL_setenv(const char name, const char value, int overwrite) CODE: if (!overwrite) { char ch = 0; const size_t len = GetEnvironmentVariableA(name, &ch, sizeof (ch)); if (len > 0) { return 0; /* asked not to overwrite existing value. / } } WHAT'S WRONG: The 3th argument to GetEnvironmentVariable (being DWORD nSize) must be the number of characters, not the number of bytes. SDL currently passes "the size of 1 char", rather "1". While it is non-breaking (1=1 after all), it is incorrect. Furthermore there is no need to specify the 2nd and 3th arguments at all. CORRECTION 1: (corrected argument_ if (!overwrite) { char ch = 0; const size_t len = GetEnvironmentVariableA(name, &ch, 1); if (len > 0) { return 0; / asked not to overwrite existing value. / } } CORRECTION 2: (stripped of unneeded code) if (!overwrite) { if (GetEnvironmentVariableA(name, NULL, 0) > 0) { return 0; / asked not to overwrite existing value. */ } }

880842cf	2016-12-31T16:14:51	Fixed bug 3531 - internal SDL_vsnprintf implementation access memory outside given buffer ranges Tristan The internal SDL_vsnprintf implementation accesses memory outside buffer. The bug existed also inside the format (%) processing, which was fixed with Bug 3441. But there is still an invalid access, if we do not have any format inside the source string and the destination string is shorter than the format string. You can use any string for this test, as long it is longer than the buffer. Example: va_list argList; char buffer[4]; SDL_vsnprintf(buffer, sizeof(buffer), "Testing", argList); The bug is located on the 'else' branch of the format char test: while (fmt) { if (fmt == '%') { ... } else { if (left > 1) { text = fmt; --left; } ++fmt; ++text; } } if (left > 0) { text = '\0'; } As you can see that text is always incremented, even when left is already one. When then on the last lines, text is assigned the NULL char, the pointer is located outside bounds.

40b571c9	2016-11-06T10:01:08	Fixed bug 3468 - _allshr in SDL_stdlib.c is not working properly Mark Pizzolato On Windows with Visual Studio, when building SDL as a static library using the x86 (32bit) mode, several intrinsic operations are implemented in code in SDL_stdlib.c. One of these, _allshr() is not properly implemented and fails for some input. As a result, some operations on 64bit data elements (long long) don't always work. I classified this bug as a blocker since things absolutely don't work when the affected code is invoked. The affected code is only invoked when SDL is compiled in x86 mode on Visual Studio when building a SDL as a static library. This build environment isn't common, and hence the bug hasn't been noticed previously. I reopened #2537 and mentioned this problem and provided a fix. That fix is provided again here along with test code which could be added to some of the SDL test code. This test code verifies that the x86 intrinsic routines produce the same results as the native x64 instructions which these routines emulate under the Microsoft compiler. The point of the tests is to make sure that Visual Studio x86 code produces the same results as Visual Studio x64 code. Some of the arguments (or boundary conditions) may produce different results on other compiler environments, so the tests really shouldn't be run on all compilers. The test driver only actually exercised code when the compiler defines _MSC_VER, so the driver can generically be invoked without issue.

73f2c541	2016-10-07T16:44:42	Fixed bug 2885 - SDL_stdinc.h doesn't need to include iconv.h Ryan C. Gordon We still include iconv.h in SDL_stdinc.h, probably because this header might have referenced the native iconv functions and types directly. Since these are hidden behind a stable ABI now and never just a #define for the system iconv, we shouldn't need this header included from a public SDL header anymore, slowing down external apps compiles and pulling tons of stuff into the namespace.
46f44f66	2016-10-04T14:25:31	Fixed potential buffer overflow in SDL_vsnprintf() (thanks, Taylor!). Fixes Bugzilla #3441. "When using internal SDL_vsnprintf(), and source string length is greater than destination, the final NULL char will be written beyond destination size. Primary issue that is SDL_strlcpy returns length of source string (SDL_PrintString()), not how much is written to destination. The destination ptr is then incremented by this length before the sanity check is done. Destination string is properly terminated, but an extra NULL char will be written beyond destination buffer length. Patch used internally is attached which fixes primary issue with SDL_strlcpy() in SDL_PrintString() and adjusts sanity checks to increment destination ptr safely."

ac444cd3	2016-01-02T10:25:53	Fixed bug 3092 - Statically link sdl2 with /MT for msvc Martin Gerhardy According to https://msdn.microsoft.com/de-de/library/2kzt1wy3%28v=vs.120%29.aspx when one is using /MT for msvc compilations the libcmt.lib is already linked to the binary. This lib includes the symbol that is now guarded (see attached patch) by the #ifndef _MT.

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().
d98cfe14	2015-06-07T20:00:20	Let's assume that if VS2005 and VS2010 do it, VS2008 probably does, too.
753f95c5	2015-06-07T19:58:42	VS2005 tweaks (thanks, Ozkan!). Fixes Bugzilla #2895. His notes: The following trivial changes make SDL2 tree (mostly) compatible with Visual Studio 2005: * SDL_stdlib.c: Similar to VS2010 and newer, VS2005 also generates memcpy(), (it also generates memset(), see below), so propagate the #if condition to cover VS2005. * SDL_pixels.c (SDL_CalculateGammaRamp): VS2005 generates a memset() call for gamma==0 case, so replace the if loop with SDL_memset(). * SDL_windowsvideo.h: Include msctf.h only with VS2008 and newer, otherwise include SDL_msctf.h * SDL_windowskeyboard.c: Adjust the #ifdefs so that SDL_msctf.h inclusion is always recognized correctly.

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.
a823982e	2015-01-05T01:41:42	Clang static analysis builds should use C runtime directly. This is a little macro magic to use malloc() directly instead of SDL_malloc(), etc, so static analysis tests that know about the C runtime can function properly, and understand that we are dealing with heap allocations, etc. This changed our static analysis report from 5 outstanding bugs to 30. 5x as many bugs were hidden by SDL_malloc() not being recognized as malloc() by the static analyzer!
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!
9c398852	2014-11-22T22:20:40	Corrected header file documentation comment.
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
1ea86978	2014-08-17T13:11:55	Removed SDL_round() because the license wasn't compatible with zlib

0d673844	2014-06-21T11:52:53	Fixed bug 2596 - SDL_SetError fails on on NULL on systems with vsnprintf sfalexrog On systems with vsnprintf call SDL_SetError fails when passed a NULL as an argument. SDL's implementation checks for NULL (as seen in the commit: https://hg.libsdl.org/SDL/rev/835403a6aec8), but system implementation may crash.

d12d7952	2014-05-10T21:48:46	Align pointer in SDL_memset before doing Uint32 loop Some more recent compilers emit SSE aligned store instructions for the loop, causing crashes if the destination buffer isn't aligned on a 32-bit boundary. This would also crash on platforms like ARM that require aligned stores. This fixes a crash inside SDL_FillRect that happens with the official x64 mingw build.
1a4c0dac	2014-05-10T11:27:43	Temporary fix for bug 2494 - Crashes due to the non thread-safe SDL_malloc/SDL_free on Windows We'll define USE_LOCKS as a temporary fix until an alternative like ptmalloc, jemalloc, or nedmalloc can be investigated. http://www.malloc.de/en/ http://www.canonware.com/jemalloc/ http://www.nedprod.com/programs/portable/nedmalloc/ SDL allocates memory very infrequently, so this is probably a decent fix for a while.
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.

35ab76d0	2013-12-11T21:17:24	Fixed bug 2050 - Obvious bugs in SDL_ltoa and SDL_lltoa pjz SDL_ltoa(-2147483648,s,10) only returns "-" because there is a bug in the code: if ( value < 0 ) { *bufp++ = '-'; value = -value; } but -(-2147483648) is still -2147483648 (0x80000000) as signed int (or long), so the following loop doesn't run at all. Similar bug are also in SDL_lltoa. BTW, there is no sanity check for radix.

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.
8574c081	2013-11-27T00:29:46	Fixed bug 2274 - SDL_ceil is incorrectly implemented when HAVE_LIBC is not defined Ghassan Al-Mashareqa The SDL_ceil function is implemented incorrectly when HAVE_CEIL is not defined (HAVE_LIBC not defined). The following code: double val = SDL_ceil(2.3); printf("%g", val); prints "2.0", as STD_ceil is defined as: double SDL_ceil(double x) { #ifdef HAVE_CEIL return ceil(x); #else return (double)(int)((x)+0.5); #endif /* HAVE_CEIL */ } This functions is used in the SDL_BuildAudioResampleCVT function of the audio subsystem (SDL_audiocvt.c), and causes a bug in that function.
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.
e7693740	2013-11-24T23:35:38	Added SDL_vsscanf().
69c5d21d	2013-10-27T21:26:46	WinRT: merged with SDL 2.0.1 codebase
12ca3ce3	2013-10-17T23:02:29	Fixed building using MinGW Our SDL_windows.h needed to be included before anything else so UNICODE is defined.
cefffd61	2013-09-05T06:59:34	Fixed bug 2082 - SDL stdlib implementation does not force upper case for %X format specifier norfanin When SDL_vsnprintf handles the %x format specifier, a boolean is set to signal forced lower case. It also should be able to signal forced upper case for the %X specifier. A boolean is not sufficient anymore. The attached patch adds an enum for the three cases: lower, upper and no change.

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.

Make sure we have iconv.h before building with it

73f2c541

2016-10-07T16:44:42

Fixed bug 2885 - SDL_stdinc.h doesn't need to include iconv.h Ryan C. Gordon We still include iconv.h in SDL_stdinc.h, probably because this header might have referenced the native iconv functions and types directly. Since these are hidden behind a stable ABI now and never just a #define for the system iconv, we shouldn't need this header included from a public SDL header anymore, slowing down external apps compiles and pulling tons of stuff into the namespace.

Fixed potential buffer overflow in SDL_vsnprintf() (thanks, Taylor!). Fixes Bugzilla #3441. "When using internal SDL_vsnprintf(), and source string length is greater than destination, the final NULL char will be written beyond destination size. Primary issue that is SDL_strlcpy returns length of source string (SDL_PrintString()), not how much is written to destination. The destination ptr is then incremented by this length before the sanity check is done. Destination string is properly terminated, but an extra NULL char will be written beyond destination buffer length. Patch used internally is attached which fixes primary issue with SDL_strlcpy() in SDL_PrintString() and adjusts sanity checks to increment destination ptr safely."

This lib includes the symbol that is now guarded (see attached patch) by the #ifndef _MT.

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().

VS2005 tweaks (thanks, Ozkan!). Fixes Bugzilla #2895. His notes: The following trivial changes make SDL2 tree (mostly) compatible with Visual Studio 2005: * SDL_stdlib.c: Similar to VS2010 and newer, VS2005 also generates memcpy(), (it also generates memset(), see below), so propagate the #if condition to cover VS2005. * SDL_pixels.c (SDL_CalculateGammaRamp): VS2005 generates a memset() call for gamma==0 case, so replace the if loop with SDL_memset(). * SDL_windowsvideo.h: Include msctf.h only with VS2008 and newer, otherwise include SDL_msctf.h * SDL_windowskeyboard.c: Adjust the #ifdefs so that SDL_msctf.h inclusion is always recognized correctly.

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

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.

Clang static analysis builds should use C runtime directly. This is a little macro magic to use malloc() directly instead of SDL_malloc(), etc, so static analysis tests that know about the C runtime can function properly, and understand that we are dealing with heap allocations, etc. This changed our static analysis report from 5 outstanding bugs to 30. 5x as many bugs were hidden by SDL_malloc() not being recognized as malloc() by the static analyzer!

[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

Align pointer in SDL_memset before doing Uint32 loop Some more recent compilers emit SSE aligned store instructions for the loop, causing crashes if the destination buffer isn't aligned on a 32-bit boundary. This would also crash on platforms like ARM that require aligned stores. This fixes a crash inside SDL_FillRect that happens with the official x64 mingw build.

Temporary fix for bug 2494 - Crashes due to the non thread-safe SDL_malloc/SDL_free on Windows We'll define USE_LOCKS as a temporary fix until an alternative like ptmalloc, jemalloc, or nedmalloc can be investigated. http://www.malloc.de/en/ http://www.canonware.com/jemalloc/ http://www.nedprod.com/programs/portable/nedmalloc/ SDL allocates memory very infrequently, so this is probably a decent fix for a while.

Fixed bug 2050 - Obvious bugs in SDL_ltoa and SDL_lltoa pjz SDL_ltoa(-2147483648,s,10) only returns "-" because there is a bug in the code: if ( value < 0 ) { *bufp++ = '-'; value = -value; } but -(-2147483648) is still -2147483648 (0x80000000) as signed int (or long), so the following loop doesn't run at all. Similar bug are also in SDL_lltoa. BTW, there is no sanity check for radix.

The following code: double val = SDL_ceil(2.3); printf("%g", val); prints "2.0", as STD_ceil is defined as: double SDL_ceil(double x) { #ifdef HAVE_CEIL return ceil(x); #else return (double)(int)((x)+0.5); #endif /* HAVE_CEIL */ } This functions is used in the SDL_BuildAudioResampleCVT function of the audio subsystem (SDL_audiocvt.c), and causes a bug in that function.

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.
