Subject: Re: [SDL] SDL 1.2.8 Prerelease
I'm sending small fix for BeOS, which prevents filling up SDL's message
queue too fast.
Without it, SDL receives "key down" messages from BeOS code, for each key
repeat (BeOS handles key repeats itself, and application can check if
received "key down" message from BeOS is first time key down, or if it's
repeat, and which repeat it is). Since there is no way for "sdl driver" to
turn off "default" SDL's key-repeat mechanism, they were working both at
the same time (and queue could be filled up very fast).
So this patch removes handling "key down" message from BeOS if it's
key_repeat "type".

Subject: [SDL] SDL_SaveBMP width bugfix
this fixes the pitch versus width difference that can happen
(especially for 8bit and 24bit (with the exact RGBAmasks) surfaces)
when you use SDL_SaveBMP. The problem was the pitch was used
instead of the width, which in some cases is much wider than the
screen area you really want to save...making for ugly crud on the
saved image borders.
This code has been tested with & without pitch overhangs...and
with the right masks for 24 bit surfaces.
I tested 8,15,16,24,32-0RGB,32-RGBA(with no SDL_SRCALPHA flag).

- there is a bug that was introduced in the kernel headers for 2.6.9

Subject: [SDL] Patch: fixing uninitilized palette
while running Valgrind over my application I found the following
problem in SDL:
The function MapNto1 allocates SDL_Color colors[256] but does not
initialize it.
SDL_DitherColors is then called which initialized the r, g and b
component, but not the 'unused' component of each color.
When Map1to1 is called from MapNto1, it runs a memcmp on the colors,
which also evaluates the unused component and therefor returns
differences much more often than necessary.
So the 'unused' component of SDL_Color should be initialized. This
patch does this by calling memset for the whole array in MapNto1 .

Subject: OS X Mouse inversion problem fix (again)
Here's yet another patch for the OS X mouse inversion
problem. This should fix the problem once and for all.
I know I've said this before, but *This time for
sure!* :)
If you recall, my last patch broke the non-OpenGL
windowed code and caused the inversion to occur there
instead. Max submitted a patch that partially reverted
the changes back which included the os version hack
which is currently the most recent CVS.
Aaron Sullivan identified and reported to the mailing
list the other day, that the last partial regression
of the code broke OS X 10.2. Looking over the results,
I'm thinking that I was slightly more successful than
I thought at unifying the code. I think I was trying
to unify the code base for OpenGL and non-OpenGL
windowed modes for all versions of the OS. It looks
like I failed at at unifying the OpenGL and non-OpenGL
code, but I did succeed at unifying the OS versions.
Thus, we no longer need the hack for the OS version
checks. The partial regression still included an OS
check which is what broke things for < 10.3.
Attached is the patch for SDL_QuartzWM.m. It basically
is a half-line change that removes one of the two
checks that decides if the mouse coordinates need to
be inverted, i.e:
if (system_version >= 0x1030 &&
(SDL_VideoSurface->flags & SDL_OPENGL) )
becomes this:
if(SDL_VideoSurface->flags & SDL_OPENGL)
With Aaron's outstanding help, we have collectively
tested:
windowed OpenGL
windowed non-OpenGL
fullscreen OpenGL
fullscreen non-OpenGL
under OS X 10.2 (Jaguar), 10.3 (Panther), and 10.4
(Tiger).
We don't have access to 10.0 or 10.1, but since the
original problem didn't materialize until 10.3, I'm
hopeful that testing 10.2 is sufficient. And now that
the code is uniform, I'm also hoping we'll be safe
moving forward to deal with future revisions of the OS
with this issue.

Subject: [SDL] [PATCH] DirectX and SDL_WINDOWID Hack
Hello, all. The IDirectInputDevice2_SetCooperativeLevel call in
SDL_dx5events.c expects to be passed a root-level HWND. More often than not,
a child window is used with the SDL_WINDOWID hack, causing the
IDirectInputDevice2_SetCooperativeLevel call to fail.
This is a small patch to SDL_dx5events.c v1.21 that fixes the problem by
retrieving a handle to the root-level ancestor of the current SDL_Window and
passing that handle to IDirectInputDevice2_SetCooperativeLevel.

Subject: Re: SDL uses obsolete OSS features
I did some work on getting OSS to work better with SDL. There have been
some problems with select which should be fixed now.
I'm having some problems in understanding what is the purpose of the
DSP_WaitAudio() routine. I added a return to the very beginning of this
routine and commendted out the define for USE_BLOCKING_WRITES. At least
lbreakout2 seems to work as well as earlier. The latencies are the same.
An ordinary blocking write does exactly the same thing than DSP_WaitAudio
does. So I would recommend using the USE_BLOCKING_WRITES approach and
removing everything from the DSP_WaitAudio routine. Also enabling
USE_BLOCKING_WRITES makes it possible to simplify DSP_PlayAudio() because
you don't need to handle the partial writes (the do-while loop).
Attached is a patch against SDL-1.2.7. After these changes SDL will use
OSS as it's designed to be used (make it as simple as possible). This code
should work with all OSS implementations because it uses only the very
fundamental features that have been there since the jurassic times.

Subject: [SDL] PATCH: Fix for release count bug in SDL_QuartzWM
SDL_QuartzWM incorrectly does [window close]; [window release];
The semantics for -[NSWindow close] are as follows:
Removes the receiver from the screen. If the receiver is set to be
released when closed, a release message is sent to the object after the
current event is completed. For an NSWindow object, the default is to
be released on closing, while for an NSPanel object, the default is not
to be released. You can use the setReleasedWhenClosed: method to change
the default behavior.
This patch simply removes the incorrect release.

Subject: Reworked audio drivers for Atari platform
These are reworked audio drivers for the Atari platform.
Previous drivers were missing some features:
- Test external clock plugged to DSP port on Atari Falcon 030.
- Ability to select internal or external clock.
So now, I generate a list of frequencies available, with the master clock
and predivisor to use. One big caveat to this: I do not have an external
clock, so I hope it works.

Subject: SDL uses obsolete OSS features
I was trying to compile SDL against the latest OSS version. It appeared
that SDL 1.2.7 is using a very old SOUND_PCM_WRITE_RATE ioctl that is
obsolete and has been removed from OSS. The right ioctl to call is
SNDCTL_DSP_SPEED. Attached is a patch (works with all OSS versions).

Subject: [Patch]: Improved menu code for SDLMain.m
the attached patch improves the menu setup for SDL apps built without a
.nib file. On 10.3, the application menus are empty with the current
SDL CVS version; after this patch, a proper app & window menu, with
"About", "Hide", "Quit", "Minimize" etc. entries are visible, just like
with the .nib enabled applications.
This *should* work on 10.2 and even 10.1, but I can't guarantee it, so
somebody should test there, ideally.
I also changed the way setupWorkingDirectory works by making use of the
Bundle APIs, that results in (IMO) less hackish code.
Finally, I added some "static" keywords to ensure that certain local
functions are not exported (that's just a paranoia change, I guess:
never pollute linker namespaces if you can avoid it).

Subject: why call arts artsc?
I, and a few other people at the mplayer-docs-mailinglist were wondering why
you decided to call arts artsc. I understand usually users have nothing to do
with libsdl, just developers, but because you can choose the audio-driver
being used by mplayer, one of which is sdl, and you can also choose the sdl
subdriver, it is necessary to have a well-known or logical name. artsc is not
the logical choice, and it's very hard to look up the right name if you don't
know what you're looking for.
