b3260e7e	2022-06-11T23:34:20	Remove macro definition for SDL_ERRBUFIZE I was looking at how errors are handled by SDL and came across this #define SDL_ERRBUFIZE which looks like a typo for SDL_ERRBUFSIZE, but either way, it looks like this isn't being used anywhere anymore because it was getting reported whenever I compile SDL with -Wunused-macros, and the last time it was mentioned in the code was from commit 09ca66b.

09ca66bf	2020-04-21T01:30:36	SDL_error: simplified error string management. This patch removes deferred error string formatting: now we do it during SDL_SetError(), so there's no limit on printf-style arguments used. Also removes stub for managing error string translations; we don't have the facilities to maintain that and the way we set arbitrary error strings doesn't really make this practical anyhow. Since the final error string is set right away and unique to the thread, we no longer need a static buffer for legacy SDL_GetError(), and we don't have to allocate 5x 128-byte argument fields per-thread. Also, since we now use SDL_vsnprintf instead of parsing the format string ourselves, there's a lot of code deleted and we have access to more robust formatting powers now. This does mean the final error strings can't be more than 128 bytes, down from the theoretical maximum of around 768, but I think this is probably okay. They might truncate but they will always be null-terminated! Fixes Bugzilla #5092.

cd79d8cc	2017-07-10T17:16:12	Fixed bug 3696 - SDL_ShowMessageBox displays different error from intended Mark Callow SDL_ShowMessageBox calls SDL_CaptureMouse which, in the UIKit driver, raises a ?That operation is not supported? error, overwriting the SDL error that an application may be trying to report. This is because UIKit SDL_CaptureMouse returns SDL_Unsupported() which ends up calling SDL_SetError() which has the following code: /* If we are in debug mode, print out an error message / SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", SDL_GetError()); The SDL_GetError call here overwrites the static buffer?.. Although an application can avoid this by using SDL_GetErrorMsg(char errstr, int maxlen) to avoid the static buffer, SDL should be fixed. The fix is simple. In SDL_SetError change SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", SDL_GetError()); to SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", error); where error is the pointer to the buffer where it assembled the message.

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().

d9f37853	2015-03-24T03:12:35	Make SDL error string formatting deal with nasty corner cases. We continued looping while maxlen > 0, but maxlen was unsigned, so an overflow would make it a large number instead of negative. Fixed. Some snprintf() implementations might return a negative value if there isn't enough space, and we now check for that. Don't overrun the SDL error message buffer, if snprintf() returned the number of chars it wanted to write instead of the number it did. snprintf is a portability mess, we should just never use the C runtime for it. Fixes Bugzilla #2049.
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
