9d9e92cf46 Fixed bug 3304 - Android black screen on resume
Richard Russell

Resuming from a suspended state results in a black screen.  This only happens when using GLES 1.1 (GLES 2 resumes correctly) and when the render target has been changed using SDL_SetRenderTarget.  This problem is new in 2.0.4.

The attached test case demonstrates the issue.

Sylvain Becker has apparently found a fix as follows:

"In the opengles leaf function (in 'src/render/opengles/SDL_render_gles.c'), it appears there is a call to 'GLES_ActivateRenderer' in 'GLES_SetRenderTarget', which is not present in opengles2. When commenting out this 'GLES_ActivateRenderer', it seems to resume fine".

This appears to fix the testcase perfectly, but I don't know whether it could have any undesirable side-effects.

e9c2dcdae8 Fixed bug 3469 - Keypresses leak to the console with 2.0.5
tvc

I believe this patch should fix it, instead of looping through all the tty's and seemingly selecting the wrong one and corrupting the console I've just made SDL open /dev/tty which is the console attached to the current process anyway.

356c2eadf4 Fixed bug 3544 - Memory freeing bug in SDL_DestroyRenderer/SDL_DestroyTexture
felix

Here's a snippet of SDL_DestroyRenderer from hg revision 10746:7540ff5d0e0e:

    SDL_Texture *texture = NULL;
    SDL_Texture *nexttexture = NULL;
    /* ... */
    for (texture = renderer->textures; texture; texture = nexttexture) {
        nexttexture = texture->next;
        SDL_DestroyTexture(texture);
    }

SDL_DestroyTexture removes the texture from the linked list pointed to by the renderer and ends up calling SDL_DestroyTextureInternal, which contains this:

    if (texture->native) {
        SDL_DestroyTexture(texture->native);
    }

If it happens that texture->native is an alias of nexttexture two stack frames up, SDL_DestroyRenderer will end up trying to destroy an already freed texture. I've had this very situation happen in dosemu2.

Bug introduced in revision 10650:a8253d439914, which has a somewhat ironic description of "Fixed all known static analysis bugs"...

41be9756f0 Fixed bug 3546 - SDL_EVDEV_is_console() uses type of wrong size when calling ioctl
Rob

When calling ioctl(fd, KDGKBTYPE, &type) in SDL_EVDEV_is_console(), we declare type as an 'int'.  This should be a 'char'.  The subsequent syscall, and kernel code, only writes the lower byte of the word.

See: http://lxr.free-electrons.com/source/drivers/tty/vt/vt_ioctl.c?v=4.4#L399

ucval = KB_101;
ret = put_user(ucval, (char __user *)arg);

I've observed intermittent behavior related to this, and I can force an error condition by using an int initialized to 0xFFFFFFFF.  The resulting ioctl will set type to 0XFFFFFF02, and the conditional return in SDL_EVDEV_is_console() will fail.

Recommend changing to char, or masking off unused bits.

992124d4de audio: Fixed SDL_AudioStreamGet() function parameters.
There was a draft of this where it did audio conversion into the final buffer,
if there was enough room available past what you asked for, but that interface
got removed, so the parameters didn't make sense (and we were using the
wrong one in any case, too!).

d024c724d1 Fixed signedness issue when blitting on a big endian platform, as reported by capehill
For example, if sR is 0 and dR is 255, we will get -255*sA casted to an unsigned value. Basically results are quite large numbers instead of the expected 0-255 range.

082132a70c Fixed binding the D-pad on some Super NES style controllers
Fixed a case where partial trigger pull could be bound to another button

There is a fundamental problem not resolved by this commit:

Some controllers have axes (triggers, pedals, etc.) that don't start at zero, but we're guaranteed that if we get a value that it's correct. For these controllers, the current code works, where we take the first value we get and use that as the zero point and generate axis motion starting from that point on.

Other controllers have digital axes (D-pad) that assume a zero starting point, and the first value we get is the min or max axis value when the D-pad is moved. For these controllers, the current code thinks that the zero point is the axis value after the D-pad motion and this doesn't work.

My hypothesis is that the first class of devices is more common and that we should solve for that, and add an exception to SDL_JoystickAxesCenteredAtZero() as needed for the second class of devices.

d359180040 Fixed bug 3519 - SDL_GetDisplayMode fails to report mode.format when using Wayland backend
Ryan C. Gordon

Kristian says you can't do it with Wayland, and that going forward, it'll just handle whatever you throw at it anyhow.

https://twitter.com/hoegsberg/status/816148272402165761

So I say we mark it SDL_PIXELFORMAT_RGB888, which is what my X11 display currently reports, and leave it at that.
