Fixed bug #1112 (retina display support)

Vittorio Giovara 2011-02-01 02:21:50 PST

with the attached patch, the opengles context will always use the maximum
screensize available; this is particularly useful for supporting retina display
on latest iphone.

please note: Apple documentation warns that using the "upscaled" gl context
actually uses more memory and bandwitdh, so it might be worth to let the user
decide whether to disable it or not, either with a flag or a sdl function...

Build fix with clang.

When building sdl 1.2.14 with the Clang compiler http://clang.llvm.org .
The build fails in src/video/mmx.h with the following error:

According to the clang developers this is a invalid inline assembly.

compile.

Updated main.c for API changes

Kees Bakker to sdl

The main.c for the template is still targeting SDL1.2. Here
is the patch to make it work for SDL1.3 (I'm hoping
the mailing lists accepts attachments.)

In this patch I have also changed the shell script that
assembles the Template. Since there is now only one lib
target (same name for "device" and "simulator" version)
I copy the simulator library to the destination with
the name libSDLSimulator.a. This is not a satisfactory
solution, because both libraries are included in the project
while only one is needed (depending on the selected
environment). However, I'm not fluent with Xcode to
say what a better solution would be.

Kind regards,
Kees Bakker

Fixed bug #1056 (Frequent crashes in Touch events by simply touching the screen)

Joseba GarcĂ­a Echebarria 2010-12-15 01:55:22 PST

I believe the crash is caused by a check not being performed on wether an
SDL_Touch element is NULL before using it in the SDL_SendTouchMotion function
in src/events/SDL_touch.c around line 400.
Judging from the rest of the code, there's a missing

if (!touch) {
return 0;
}

before using "touch" as SDL_GetFinger(), SDL_GetFingerIndexId() use
touch->num_fingers without checking.

I can attach a patch if you like. It seems pretty straightforward, though.

I have yet to discover why touch is being returned as NULL as this error is
only triggered when an actual gesture has been performed, maybe something
related to SDL_AddTouch()?

Removed completely non-portable event thread hack.
Next I'll be working on generalizing the event sources and making the event queue lock-free. :)
