e2dbed9c	2020-05-29T13:05:37	SDL_blit: Fix undefined bitshift operations Arithmatic operations promote Uint8 to signed int. If the top bit of a Uint8 is set, and it is left shifted 24 places, then the result is not representable in a signed 32 bit int. This would be undefined behaviour on systems where int is 32 bits.

715e070d	2019-09-06T08:50:19	SDL_blit_N.c: Correct vec_perm() application on little-endian 64-bit PowerPC The LE transformation for vec_perm has an implicit assumption that the permutation is being used to reorder vector elements (in this case 4-byte integer word elements), not to reorder bytes within those elements. Although this is legal behavior, it is not anticipated by the transformation performed by the compilers. This causes pygame-1.9.1 test failure on PPC64LE because blitted pixmaps are corrupted there due to how SDL uses vec_perm().

6e35e421	2018-10-01T14:43:03	Working on bug 3921 - Add some Fastpath to BlitNtoNKey and BlitNtoNKeyCopyAlpha Sylvain I did various benches. with clang 6.0.0 on linux, and ndk-r16b on android (NDK_TOOLCHAIN_VERSION=clang). - still see a x10 speed factor. - with duff_loops, it does not use vectorisation (but doesn't seem to be a problem). on linux my patch is already at full speed on -O2, whereas the duff_loops need -O3 (200 ms at -03, and 300ms at -02). I realized that on Android, I had a slight variation which fits best. both on linux with -O2 and -O3, and on android with 02/03 and armeabi-v7a/arm64. Here's the patch.

The warnings were like the following: In file included from src/video/SDL_blit_N.c:26:0: src/video/SDL_blit_N.c: In function 'BlitNtoNKeyCopyAlpha': src/video/SDL_blit_N.c:2421:24: warning: declaration of 'Pixel' shadows a previous local [-Wshadow] Uint32 Pixel = ((src32 & rgbmask) == ckey) ? dst32 : src32; ^ src/video/SDL_blit.h:475:21: note: in definition of macro 'DUFFS_LOOP8' case 0: do { pixel_copy_increment; / fallthrough */ \ ^ src/video/SDL_blit_N.c:2419:13: note: in expansion of macro 'DUFFS_LOOP' DUFFS_LOOP( ^ src/video/SDL_blit_N.c:2399:12: warning: shadowed declaration is here [-Wshadow] Uint32 Pixel; ^

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().

74d83ead	2015-05-04T21:47:40	Fixed bug 2976 - Fix RGBA<->RGBA blit that was broken with the optimization from Bug 11 id.zeta The optimization from Bug 11 added a code branch on cases where the source RGB masks match the destination RGB masks and a optimized blit function Blit4to4MaskAlpha that always overrides the source alpha info would be chosen. Unfortunately, the branch also errorneously took over the RGBA<->RGBA blitting cases where the source alpha info should be copied, while they would instead get overriden in Blit4to4MaskAlpha. The attached patch fixes that by handling the RGBA<->RGBA cases correctly in that branch with the original BlitNtoNCopyAlpha as well as uses an optimized Blit4to4CopyAlpha along the same vein.

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.

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.

SDL_blit: Fix undefined bitshift operations Arithmatic operations promote Uint8 to signed int. If the top bit of a Uint8 is set, and it is left shifted 24 places, then the result is not representable in a signed 32 bit int. This would be undefined behaviour on systems where int is 32 bits.

SDL_blit_N.c: Correct vec_perm() application on little-endian 64-bit PowerPC The LE transformation for vec_perm has an implicit assumption that the permutation is being used to reorder vector elements (in this case 4-byte integer word elements), not to reorder bytes within those elements. Although this is legal behavior, it is not anticipated by the transformation performed by the compilers. This causes pygame-1.9.1 test failure on PPC64LE because blitted pixmaps are corrupted there due to how SDL uses vec_perm().

Working on bug 3921 - Add some Fastpath to BlitNtoNKey and BlitNtoNKeyCopyAlpha Sylvain I did various benches. with clang 6.0.0 on linux, and ndk-r16b on android (NDK_TOOLCHAIN_VERSION=clang). - still see a x10 speed factor. - with duff_loops, it does not use vectorisation (but doesn't seem to be a problem). on linux my patch is already at full speed on -O2, whereas the duff_loops need -O3 (200 ms at -03, and 300ms at -02). I realized that on Android, I had a slight variation which fits best. both on linux with -O2 and -O3, and on android with 02/03 and armeabi-v7a/arm64. Here's the patch.

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().

Fixed bug 2976 - Fix RGBA<->RGBA blit that was broken with the optimization from Bug 11 id.zeta The optimization from Bug 11 added a code branch on cases where the source RGB masks match the destination RGB masks and a optimized blit function Blit4to4MaskAlpha that always overrides the source alpha info would be chosen. Unfortunately, the branch also errorneously took over the RGBA<->RGBA blitting cases where the source alpha info should be copied, while they would instead get overriden in Blit4to4MaskAlpha. The attached patch fixes that by handling the RGBA<->RGBA cases correctly in that branch with the original BlitNtoNCopyAlpha as well as uses an optimized Blit4to4CopyAlpha along the same vein.

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

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.

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!

[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

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.
