Subject: Modification for RISC OS SDL port
My name is Alan Buckley and I have been working on the RISC OS SDL port.
I've attached a modification to SDL_WimpVideo.c to this email that ensures
the Window is displayed immediately when the video mode is set to a windowed
mode.

Subject: [patch] SDL-1.2.5 + FreeBSD joystick axes, hat fixes
Hello again! When I sent in some SDL fixes last December, I found out
they'd already been fixed in the CVS version. This time, I checked the
repository before bugging you. =)
I'm using SDL-1.2.5 on a FreeBSD 4.6.2-RELEASE system, and in the course
of getting my multi-analog-axis USB controller (with a hat switch!)
working with d2x-sdl -- the SDL port of the Descent 2 engine -- I came
across a few problems:
1) The second analog stick is reported as a slider in one direction, and
"Rz" in the other. SDL was ignoring the Rz axis, so I added Rx/Ry/Rz to
the set of things SDL considers to be axes.
2) After the above change, the set of JOYAXE_* axes for my gamepad was
{0,1,3,7}; however, d2x-sdl expects the axes to be contiguously numbered
from 0, which seems like a pretty reasonable expectation, rather than
having to scan the entire space of axes that SDL may or may not have.
So, I added a table lookup which maps the JOYAXE_* axis numbers to 0,1,...
in the order they're detected by SDL_SYS_JoystickOpen(), when reporting
them to the application. I also added a function "usage_to_joyaxe()"
which maps the USB HUG_* usage values to JOYAXE_values, since the repeated
case statements testing for HUG_* were getting out of hand.
3) The BSD joystick driver had no hat support, so I added it. It looks
like our USB library can only support one hat switch per device, which
makes life easy.
The patch against SDL-1.2.5 which implements these changes is at:
http://www.caida.org/~jabrown/patches/sdl-1.2.5-bsdhat.diff
After applying, SDL's "testjoystick" reports all activity from my gamepad
correctly, and d2x works too (though it needed some other fixes).
Moving on...
There is also a problem with slightly different USBHID library interfaces
on different versions of FreeBSD. I wasn't going to mention this since the
FreeBSD port for SDL-1.2.5 (and not SDL itself) was doing the FreeBSD
version-specific patching, so I e-mailed the port maintainer with this
change. However, I see that you've incorporated the FreeBSD
version-checking stuff into the CVS version of SDL, so now it's relevant
for you too.
The problem is, the FreeBSD #if tests don't work right for FreeBSD
4.6.2-RELEASE. There may be other versions with this problem, but I've
only tested 4.6.2-R. The following patch against your latest CVS version
fixes this:

I hope this is all useful to you. I've been getting myself dizzy playing
Descent 2 with it, all morning!

P.S. My USB controller is a Thrustmaster Firestorm Dual Analog 2. That's
probably irrelevant, but I threw it in for completeness.

Subject: SDL Active Events Patch
Hi Guys,
I was reading sdl-devel the other day and remembered we don't handle
SDL_APPACTIVE and SDL_APPMOUSEFOCUS. I hacked together a quick patch to
do just this. One thing to note - there are actually two ways to
"iconify" the SDL window (which sets SDL_APPACTIVE): hiding the entire
application (for example, option-click on some other window) and
minimizing the window to the dock. I treat both as SDL_APPACTIVE, since
the window is no longer visible.
Cheers,
Darrell

Subject: Yet another OS X cursor bug
The synopsis:
1. Call SDL_ShowCursor(0);
2. Call SDL_SetVideoMode();
3. Call SDL_GetEvent();
3. Call SDL_ShowCursor(1);
The result: Sometimes the cursor doesn't come back! Ack! Oddly enough,
it does come back when mousing over the dock or clicking in the menu
bar. But that's besides the point.
The reason why this is happening is a flaw in the handling of
activation/deactivation events. The short explanation is that the
HideCursor() and ShowCursor() calls must be balanced, but if the cursor
was initially hidden, HideCursor() was called again on the activate
event - so now the next ShowCursor() fails (as does the next, and the
next, for some reason).
So, here's the patch. All it does is keep track of the
HideCursor()/ShowCursor() calls so that they will always be balanced.

Subject: [SDL] First patch concerning 4.3 and refresh rates
OK, here's my first draft of the patch for the above subject.
A short explanation:
X 4.3 introduces many more modelines than older versions. This would be
fine, except it introduces many modes with the *same* resolution but
different refresh rates. And SDL won't necessarily pick the one with the
highest refresh rate.
So this patch restores SDL to X 4.2 functionality. That is, there is only
ever one refresh rate *per* resolution, and it is the highest possible.
This functionality can be totally disabled by using the environment
variable 'SDL_VIDEO_X11_USE_ALL_MODES' set equal to 1.

Subject: SDL patch: FreeBSD joystick support.
This patch deals with the recent changes in FreeBSD.
We're making an effort not to diverge our libusbhid from NetBSD's.

Subject: [SDL][PATCH] 2 patches for sdl
Here are 2 patches for SDL:
- One is to put the dummy video drivers at the end of the
video drivers list. It gave me problems, when
SDL_VIDEODRIVER is not set, and the dummy driver is used
instead of the platform's driver, just because it is
always available. So the dummy driver must always be at
the end of the list. I suppose picogui and dc video
drivers also don't work.

Subject: Makefile.am fix
I fixed the Makefile.am which lacked many defines.
With this patch SDL on DirectFB doesn't crash on
startup immediately.

Subject: SDL x11 video mode selection bug
Hi, I've found an oddity with video mode selection. I recently added a bunch of
oddball video modes to my XF86Config, to support weird resolutions xine &
mplayer need if I don't want to beat my cpu up with video scaling.
Since adding them, SDL started picking the biggest video mode it could find
that matched the height constraint. Getting a narrow vertical strip of
QuakeForge (I code for the project, so needless to say it's my favorite test)
in the middle of an 800x480 screen, instead of the 640x480 I asked for
annoys me tremendously.
So here's a patch that tries a bit harder to get an exact match. I didn't
touch the XiG section, since I can't test that, but I'd bet a similar patch
would prevent similar problems there.

Subject: [SDL] Small patches for SDL
- One for SDL, which removes check for SDL_VIDEODRIVER in the Atari video
drivers. It is unnecessary 'cause it is done in SDL_video.c
