Sam Lantinga d9e1036e 2017-10-06T16:17:50 Fixed potential overflow in surface allocation (thanks Yves!)
Sam Lantinga 312da262 2017-10-05T09:37:28 Fixed bug 3854 - arguments to dbus_type_is_basic() were incorrect Aaron As of 2.0.6, all of my games are failing with the following error: process 31778: arguments to dbus_type_is_basic() were incorrect, assertion "dbus_type_is_valid (typecode) || typecode == DBUS_TYPE_INVALID" failed in file dbus-signature.c line 322. This is normally a bug in some application using the D-Bus library. D-Bus not built with -rdynamic so unable to print a backtrace (patch by Ozkan Sezer)
Brandon Schaefer db20e71d 2017-10-02T10:50:33 Fixed bug 3855 - Memory leak in SDL_FreeSurface

Brandon Schaefer e27f12e0 2017-09-29T10:07:37 wayland: Fix bug 3814 -Wmissing-field-initializers
Sam Lantinga aad58c62 2017-09-29T07:44:30 Fixed bug 3852 - SDL_FreeSurface deallocates surface->map even if the surface is not yet freed Evgeny Kapun Commit 490bb5b49f11 [1], which was a fix for bug #3790, introduced a new bug: now, calling SDL_FreeSurface(surface) deallocates surface->map even if there are other references to the surface. This is bad, because some functions (such as SDL_ConvertSurface) assume that surface->map is not NULL.
Sam Lantinga 54685787 2017-09-26T15:07:35 Fixed bug 3847 - Hit Test x coordinate wrong on secondary monitor Robert Turner SDL_windowsevents.c contains code to retrieve the x and y coordinate for a requested hit test. It does this as follows: POINT winpoint = { (int) LOWORD(lParam), (int) HIWORD(lParam) }; LOWORD(lParam) does not correctly mask off high bits that are set if the point is on a second (or third, etc.) monitor. This effectively offsets the x-coordinate by a large value. MSDN documentation suggests that LOWORD() and HIWORD() are the wrong macros for the task, instead suggesting we should be doing something like the following: POINT winpoint = { GET_X_LPARAM(lParam), GET_Y_LPARAM(lParam) }; Testing this change on my Windows 10 machine with 2 monitors gives the correct results.

Sam Lantinga 499f928c 2017-09-22T07:15:41 borderless windows will have WM_NCCALCSIZE return 0 for the non-client area. When this happens, it looks like windows will send a resize message expanding the window client area to the previous window + chrome size, so shouldn't need to adjust the window size for the set styles.
Sam Lantinga 3176a7f5 2017-09-22T07:11:36 sdl - Fixing rendering borderless window. Need to force windows to send a WM_NCCALCSIZE then return 0 for non-client area size. - Adding WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX to borderless windows, for reasons noted in comments. - Fix SetupWindowData() setting SDL_WINDOW_BORDERLESS. This was being cleared at window creation, causing hanlding for the first WM_NCCALCSIZE message to fail

Ryan C. Gordon 6d206a7b 2017-09-22T07:42:24 audio: Stream resampling now saves some samples from previous run for padding. Previously, the padding was silence, which was a problem when streaming since you would sample a little bit of this silence between each buffer. We still need a means to get padding data for the right hand side, but this patch makes the resampler output more correct.

Sam Lantinga 5ae90ef6 2017-09-21T01:22:40 Fixed bug 3788 - software renderer crashes in SDL_RenderCopyEx with rotation and dstrect w or h is 0 Anthony This is what's making the software renderer crash with rotated destination rectangles of w or h = 0: SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "2");
Sam Lantinga 8b660c50 2017-09-21T00:55:29 Added some missing "extern" declarations
Ryan C. Gordon 1a3b95a1 2017-09-21T02:51:14 audio: Replaced the resampler. Again. This time it's using real math from a real whitepaper instead of my previous amateur, fast-but-low-quality attempt. The new resampler does "bandlimited interpolation," as described here: https://ccrma.stanford.edu/~jos/resample/ The output appears to sound cleaner, especially at high frequencies, and of course works with non-power-of-two rate conversions. There are some obvious optimizations to be done to this still, and there is other fallout: this doesn't resample a buffer in-place, the 2-channels-Sint16 fast path is gone because this resampler does a _lot_ of floating point math. There is a nasty hack to make it work with SDL_AudioCVT. It's possible these issues are solvable, but they aren't solved as of yet. Still, I hope this effort is slouching in the right direction.
Ryan C. Gordon f40bd5ee 2017-09-21T02:06:53 audio: removed my perl experiment script.
Mark Callow 3c45e662 2017-09-21T14:01:12 macOS: remove unneeded #includes.

Alex Szpakowski d452b89f 2017-09-20T11:01:32 iOS: I don't think SDL compiles with the iOS 7 SDK anymore, so we might as well drop the #ifdefs trying to guard for that.

Ryan C. Gordon 93583d46 2017-09-09T21:17:46 alsa: removed snd_pcm_wait() call before writing to playback device. This would cause playback problems in certain situations, such as on the Raspberry Pi. The device that the wait was added for seems to not benefit from it in modern times, and standard desktop Linux seems to do the right thing when a USB device is unplugged now, without this patch. Fixes Bugzilla #3599.
Sam Lantinga b2ba8963 2017-09-09T11:00:25 Fixed bug 3809 - Restore after maximize leads to wrong size Andreas Falkenhahn My app opens a 640x480 window. When I click on the window's maximize button, the window correctly fills the entire screen and loses its borders. But clicking on the restore button now doesn't restore the window to its original 640x480 size. Instead, the window size is identical to the screen size now. The only difference to the previous state is that the window now has borders again but it isn't restored to 640x480.
Sam Lantinga 676c3a92 2017-09-09T10:31:44 Fixed bug 3719 - Cocoa - Incorrect window size when leaving fullscreen bastien.bouclet The window is now resized to its specified size, but it moves to the top left corner of the screen. That is unexpected because neither the user nor the program moved it there. Test program attached (the same one as before).
Sam Lantinga fcd9c190 2017-09-09T09:31:12 Fixed window size when leaving fullscreen mode (thanks Eric!)
Sam Lantinga f465f24d 2017-09-09T08:36:37 Fixed bug 3760 - RWops doesn't check for integer overflow when stdio_fseek only supports 32 bits Simon Hug When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug. The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros. It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config. And there's an additional error message for when ftell fails.
Sam Lantinga 9a73909b 2017-09-09T08:20:56 Fixed bug 3808 - fix a typo in SDL_stretch.c Ozkan Sezer The following patch fixes a minor _MSC_VER typo in SDL_stretch.c, and also does a tiny tidy-up for assembly opcodes cpp checks.
Sam Lantinga 222d25ad 2017-09-08T22:21:01 Fixed bug 3805 - Why is there no --enable-video-rpi option in configure? Andreas Falkenhahn When compiling SDL for the Raspberry Pi, I have to use the --host parameter to enable compilation of the native Raspberry Pi video driver, like so: --host=arm-raspberry-linux-gnueabihf It took me a while to figure out that this was necessary in order to have the native Raspberry Pi video driver compiled in. I think it would be better if there was an option like --enable-video-rpi that could be passed to configure and that would also show up when saying configure --help. Currently, it?s rather difficult to figure out that you have to use the --host parameter with arm-raspberry-linux-gnueabihf in order to get Raspberry Pi video support. It?s also somewhat inconsistent because most other video drivers can in fact be enabled/disabled through specific configure parameters but there is no such parameter for the native Raspberry Pi video driver.
Sam Lantinga e8059221 2017-09-08T18:26:25 Fixed bug 3806 - Fixes for MSVC compiler warnings Simon Hug These are the remaining compiler warnings I see in the current tip cb049cae7c3c. - SDL_test_log.c defines _CRT_SECURE_NO_WARNINGS without checking if it was already set. - SDL_windowskeyboard.c converts integers to pointers without going over the (U)INT_PTR types. That bothers MSVC.

Sam Lantinga c8e3e0c4 2017-09-06T01:10:10 Fixed bug 3799 - SDL_CreateWindow fails with SDL_WINDOW_VULKAN (libvulkan.so.1 not found) Manuel Sabogal Android NDK defines Vulkan as libvulkan.so, not libvulkan.so.1. This is causing the program to not being able to create a window using SDL_WINDOW_VULKAN. To fix this issue just change the line http://hg.libsdl.org/SDL/file/bbaec41e93b5/src/video/android/SDL_androidvulkan.c#l53 from "libvulkan.so.1" to "libvulkan.so"
Ryan C. Gordon c9e73c3e 2017-09-05T16:15:54 x11: make sure SDL_GetGlobalMouseState notices mouse warping through SDL APIs.
Sam Lantinga 0782f9be 2017-09-05T08:24:38 Fixed bug 3273 - Fix for slow video subsystem initialization when using XRandR. Mart?n Golini I'm having a very slow initialization of the video subsystem that locks the window creation for about 500 ms ( tested in at least 4 different systems ). What i found is that X11_InitModes_XRandR is using XRRGetScreenResources, that explicitly ask to poll the hardware for changes. This is not really necessary since if the data is already available you can use XRRGetScreenResourcesCurrent. I attached a tentative patch that fix this issue. With the patch there's no lock when the subsystem is initialized and the window creation is instant in my applications. The patch only uses XRRGetScreenResourcesCurrent in X11_InitModes_XRandR but it could be potentially used in X11_GetDisplayModes and X11_SetDisplayMode.

Sam Lantinga 67f9348b 2017-09-04T11:46:14 Fixed bug 3790 - Memory leak with surfaces blitting on each other bastien.bouclet When creating two surfaces and blitting them onto the other, SDL's internal reference counting fails, and one of the surfaces is not freed when calling SDL_FreeSurface. Example code : SDL_Surface *s1 = SDL_CreateRGBSurfaceWithFormat(0, 640, 480, 32, SDL_PIXELFORMAT_ARGB8888); SDL_Surface *s2 = SDL_CreateRGBSurfaceWithFormat(0, 640, 480, 32, SDL_PIXELFORMAT_ARGB8888); SDL_BlitSurface(s1, NULL, s2, NULL); SDL_BlitSurface(s2, NULL, s1, NULL); SDL_FreeSurface(s2); SDL_FreeSurface(s1); With this example, s1 is not freed after calling SDL_FreeSurface, its refcount attribute is still positive.
David Ludwig 532446a6 2017-09-03T17:33:49 macOS: bug-fix for #3793, "fullscreen toggle does not maintain SDL_Renderer's logical size" This also seems to fix the follow-up issue in bug #3719, whereby the initial fix caused the SDL window to move, after transitioning from fullscreen to windowed-mode
Ryan C. Gordon 167398b3 2017-09-02T19:35:32 video: Let video targets optionally decide their default OpenGL configs. This is necessary because the Raspberry Pi is a strange beast, that believes it has OpenGL support (through glX?) but generally has GLES2 support. So when using the raspberry video target, we need to force this to default to a GLES2 context, or by default SDL_CreateWindow() will fail, deep down when it tries to load the proper GL library. Fixes testsprite2 (and basically everything else that wasn't testgles2) when run on a Raspberry Pi without a X server. Please note that other targets might also need this filled in, the Raspberry Pi is just the most prominent and readily-available System-On-A-Chip style thing on my desk. :)
Ryan C. Gordon 3267398d 2017-09-02T16:41:14 sndio: Patched to compile if SIO_DEVANY isn't defined. (It isn't in whatever Raspbian is currently shipping.)
Sam Lantinga c26946e9 2017-09-01T12:54:38 Fixed bug 3792 - [KMS/DRM] Wrong GBM format Romain Tisserand Using KMS/DRM driver from WIP SDL2.0.6 on Linux/ARM SoC RockChip RK3328 (ARM Mali 450 MP2 GPU). The current code is using GBM_BO_FORMAT_XRGB8888 as GBM buffer format specifier. The Mali driver (it has been confirmed some other vendor implementations too) expects GBM_FORMAT_XRGB8888. The Mesa implementation is actually handling both values as the same, but it's not implemented like this into every gbm.h vendor header. https://github.com/ideak/mesa/blob/master/src/gbm/backends/dri/gbm_dri.c So with stock SDL2 on my card (Mali vendor implementation), it does not work, eglCreateWindowSurface fails, and gbm_is_format_supported fails too (with the BO variant). It runs fine with GBM_FORMAT_XRGB8888. Here is a link of the gbm.h from Mali user-space driver : https://github.com/rockchip-linux/libmali/blob/rockchip/include/gbm.h

Looking at the code in SDL_EGL_CreateContext - if gl_config.flags is non-zero, it looks like the code in the section guarded with "#ifdef EGL_KHR_create_context" should be executed - but it apparently isn't. Is it possible this section hasn't been compiled into the pre-built libraries? If I build SDL2.dll myself using the Visual C++ solution (VS2015 Community Update 3) then the call succeeds as I expect
Sam Lantinga 8fc1fb08 2017-08-29T21:42:22 Fixed bug 3719 - Cocoa - Incorrect window size when leaving fullscreen bastien.bouclet When exiting a "fullscreen space" on OS X, windows don't go to their defined "windowed mode size", but go back to their previous size. Steps to reproduce: 1. Create a windowed mode SDL window 2. Toggle it to fullscreen with the SDL_WINDOW_FULLSCREEN_DESKTOP flag 3. While in fullscreen, change the windowed mode size using SDL_SetWindowSize 4. Toggle the window back to windowed mode Expected result: - The window has the size specified during step 3. Actual result: - The window has the size specified when creating the window in step 1. Attached is a minimal reproduction test case. The attached test case works as expected on X11 and Windows.

There is no conditional compiling in SDL_cocoametalview.m either, so --disable-video-vulkan doesn't help with anything. (The configury doesn't check darwin for x86_64 either, but it's another story.) I cross-build against 10.8 SDK on linux using clang-3.4.2 and this is a problem for me. Will this be fixed?
Sam Lantinga d619d885 2017-08-28T21:42:39 Fixed bug 3662 - Error message when using the audio conversion setup without an initialized audio subsystem is a bit vague Simon Hug This issue actually raises the question if this API change (requirement of initialized audio subsystem) is breaking backwards compatibility. I don't see the documentation saying it is needed in 2.0.5.
Ryan C. Gordon b128e880 2017-08-29T00:41:45 audio: A whole bunch of improvements to audio conversion (thanks, Solra!). "Major changes, roughly in order of appearance: - Use float math everywhere, instead of promoting to double and casting back all the time. - Conserve sound energy when downmixing any channel into two other channels. - Add a QuadToStereo filter. (The previous technique of reusing StereoToMono never worked, since it assumed an incorrect channel layout for 4.0.) - Add a 71to51 filter. This removes just under half of the cases the previous code would silently break in. - Add a QuadTo51 filter. More silent breakage fixed. - Add a 51to71 filter, removing another almost-half of the silently broken cases. - Add 8 to the list of values SDL_SupportedChannelCount will accept. - Change SDL_BuildAudioCVT's channel-related logic to handle every case, and to actually fail if it fails instead of silently corrupting sound data and/or crashing down the road." (Note that SDL doesn't otherwise support 7.1 audio yet, but hopefully it will soon and the 7.1 converters are an important piece of that. --ryan.) Fixes Bugzilla #3727.
Ryan C. Gordon 620f5342 2017-08-29T00:36:17 stdlib: An implementation of SDL_scalbn using ldexp() (thanks, Ozkan!). Fixes Bugzilla #3767.
Ryan C. Gordon a0cd7d6b 2017-08-29T00:02:04 audio: Converting audio samples from int to float was using wrong equation. Fixes Bugzilla #3775.
