ulatekh ec58a817 2022-10-05T19:26:09 Fixes made in response to running a static code analyzer under MS Windows. Most of these are probably harmless, but the changes to SDL_immdevice.c and SDL_pixels.c appear to have fixed genuine bugs. SDL_audiocvt.c: By separating the calculation of the divisor, I got rid of the suspicion that dividing a double by an integer led to loss of precision. SDL_immdevice.c: Added a missing test, one that could have otherwise led to dereferencing a null pointer. SDL_events.c, SDL_gamecontroller.c, SDL_joystick.c, SDL_malloc.c, SDL_video.c: Made it clear the return values weren't used. SDL_hidapi_shield.c: The size is zero, so nothing bad would have happened, but the SDL_memset() was still being given an address outside of the array's range. SDL_dinputjoystick.c: Initialize local data, just in case IDirectInputDevice8_GetProperty() isn't guaranteed to write to it. SDL_render_sw.c: drawstate.viewport could be null (as seen on line 691). SDL.c: SDL_MostSignificantBitIndex32() could return -1, though I don't know if you want to cope with that (what I did) or SDL_assert() that it can't happen. SDL_hints.c: Replaced boolean tests on pointer values with comparisons to NULL. SDL_pixels.c: Looks like the switch is genuinely missing a break! SDL_rect_impl.h: The MacOS static checker pointed out issues with the X comparisons that were handled by assertions; I added assertions for the Y comparisons. SDL_yuv.c, SDL_windowskeyboard.c, SDL_windowswindow.c: Checked error-result returns.

chalonverse f317d619 2022-07-01T13:59:14 Xbox GDKX support (#5869) * Xbox GDK support (14 squashed commits) * Added basic keyboard testing * Update readme * Code review fixes * Fixed issue where controller add/removal wasn't working (since the device notification events don't work on Xbox, have to use the joystick thread to poll XInput)

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().

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 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.
Ryan C. Gordon 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!
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.
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 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.
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 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
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.
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.
