Sam Lantinga 0d763800 2023-03-09T15:10:00 Code style: changed "sizeof foo" to "sizeof(foo)" (thanks @sezero!) (cherry picked from commit c6443d86c92e962683a1efe5f123a144988875b5)

Sam Lantinga b8d85c69 2022-11-30T12:51:59 Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594 (cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)

Pierre Wendling 501a4991 2022-05-05T18:44:32 Add clang-format on/off comments where necessary. Comments were added in places where INDENT-ON/OFF comments are. Places like stdlib's asm don't need it as clang-format doesn't try to indent it.

nia a5f3ea14 2021-03-10T09:36:46 netbsdaudio: Handle ioctls failing A user reported that the mpv video player hangs after attempting to set an unsupported number of channels with the SDL audio output, because it thinks it's successfully opened the device. This makes the failure graceful.
Sam Lantinga 50ea3b77 2021-01-08T10:09:37 Fixed bug 5080 - SDL_netbsdaudio: Always use the device's preferred frequency Nia Alarie The NetBSD kernel's audio resampling code is much simpler and lower quality than libsamplerate. Presumably, if SDL always performs I/O on the audio device in its native frequency, we can avoid resampling audio in the kernel and let SDL do it with libsamplerate instead.

Sam Lantinga 9525f972 2020-04-05T10:44:51 Fixed bug 5076 - SDL_netbsdaudio: Add support for 32-bit LPCM Nia Alarie The kernel supports this, make SDL expose it so it can be used.

Sam Lantinga 15bae953 2019-06-08T13:03:36 Fixed bug 4642 - Rework SDL_netbsdaudio to improve performance Nia Alarie The NetBSD audio driver has a few problems. Lots of obsolete code, and extremely bad performance and stuttering. I have a patch in NetBSD's package system to improve it. This is my attempt to upstream it. The changes include: * Removing references to defines which are never used. * Using the correct structures for playback and recording, previously they were the wrong way around. * Using the correct types ('struct audio_prinfo' in contrast to 'audio_prinfo') * Removing the use of non-blocking I/O, as suggested in #3177. * Removing workarounds for driver bugs on systems that don't exist or use this driver any more. * Removing all usage of SDL_Delay(1) * Removing pointless use of AUDIO_INITINFO and tests that expect AUDIO_SETINFO to fail when it can't. These changes bring its performance in line with the DSP audio driver.

Sam Lantinga fb835f9e 2017-08-14T20:22:19 Fixed bug 2330 - Debian bug report: SDL2 X11 driver buffer overflow with large X11 file descriptor manuel.montezelo Original bug report (note that it was against 2.0.0, it might have been fixed in between): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733015 -------------------------------------------------------- Package: libsdl2-2.0-0 Version: 2.0.0+dfsg1-3 Severity: normal Tags: patch I have occasional crashes here caused by the X11 backend of SDL2. It seems to be caused by the X11_Pending function trying to add a high number (> 1024) file descriptor to a fd_set before doing a select on it to avoid busy waiting on X11 events. This causes a buffer overflow because the file descriptor is larger (or equal) than the limit FD_SETSIZE. Attached is a possible workaround patch. Please also keep in mind that fd_set are also used in following files which may have similar problems. src/audio/bsd/SDL_bsdaudio.c src/audio/paudio/SDL_paudio.c src/audio/qsa/SDL_qsa_audio.c src/audio/sun/SDL_sunaudio.c src/joystick/linux/SDL_sysjoystick.c -------------------------------------------------------- On Tuesday 24 December 2013 00:43:13 Sven Eckelmann wrote: > I have occasional crashes here caused by the X11 backend of SDL2.

I personally experienced this problem while hacking on the python bindings package for SDL2 [1] (while doing make runtest). But it easier to reproduce in a smaller, synthetic testcase.

Ryan C. Gordon a7fc2822 2017-05-24T19:56:59 audio: rename bsd target to netbsd. Apparently this is no longer a generic BSD audio target, and hasn't been for years, so rename it for NetBSD.
