Fixed bug 4283 - SDL's version of memset is different from libc's
janisozaur
memset's documentation reads:
* The memset() function shall copy c (converted to an unsigned char) into each of the first n bytes of the object pointed to by s. (http://pubs.opengroup.org/onlinepubs/9699919799/functions/memset.html)
* Sets the first count characters of dest to the character c. (https://msdn.microsoft.com/en-us/library/1fdeehz6.aspx)
* write a byte to a byte string (https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/memset.3.html)
The highlight here is they all mean a single _byte_, even though memset receives a parameter of type int, which can hold more data than a single byte. SDL's implementation of memset, however, does not clear any of the higher bits, causing an erroneous behaviour when passed an argument bigger than 0xff.

make sure SDL_vsnprintf() nul terminates if it is using _vsnprintf
The change makes sure that SDL_vsnprintf() nul terminates if it is
using _vsnprintf() for the job.
I made this patch for Watcom, whose _vsnprintf() doesn't guarantee
nul termination. The preprocessor check can be extended to windows
in general too, if required.
Closes bug #3769.

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. */
}
}

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.

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.

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."

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.

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

from an SDL app with Alt-Tab and had to be pressed again.

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.

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.

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.

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.
