Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
Philipp Wiesemann e3f9bf33 2015-02-08T22:50:16 Fixed two inconsistencies on failed allocation.
Philipp Wiesemann fe586d07 2015-02-08T21:25:37 Fixed three memory leaks on failed allocation.
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
David Ludwig 70438be2 2014-12-03T10:55:23 WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!
Philipp Wiesemann 9c398852 2014-11-22T22:20:40 Corrected header file documentation comment.
Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam
Sam Lantinga 05cff792 2014-08-24T00:02:12 Fixed bug 2699 - possible memory leak in GL_RenderReadPixels Benoit Pierre If glReadPixels returns an error, than the temporary buffer is not deallocated
Sam Lantinga c6a2382c 2014-08-14T21:31:50 Take advantage of GL_ARB_texture_non_power_of_two when it's available
Sam Lantinga 6fef39d6 2014-08-06T11:34:54 Added NV12 and NV21 texture support for OpenGL and OpenGL ES 2.0 renderers
Sam Lantinga dfc7535f 2014-07-26T16:52:26 Fixed bug 2657 - Memory leak in GL_CreateTexture function Nitz In GL_CreateTexture function: if (GL_CheckError("glGenTexures()", renderer) < 0) { SDL_free(data); return -1; } Here only data is getting free but data->pixels getting leak. So have to free data->pixels before free data.
Sam Lantinga d65ac778 2014-06-22T02:48:43 Restore window OpenGL state if creating an OpenGL renderer fails
Sam Lantinga af50403e 2014-06-15T18:09:39 Fixed bug 2575 - Current GL context tracking fails Ronie Salgado The GL Renderer current context tracking fails when one window is used with an SDL renderer but another separate window is used with a user handled OpenGL context. Attached is a small program that reproduces this bug, at least in some Linux machines where an OpenGL renderer is provided by default. Expected Output: -"First window" should be blue. -"Second window" should be green. Gotten Output: - "First window" black. - "Second window" blue. What happened: The renderer created for the "first window" ends rendering into the "second window" OpenGL context. Bug location: SDL_render_gl.c - line 286 on hg: static SDL_GLContext SDL_CurrentContext = NULL; When making SDL_GL_MakeCurrent from the user perspective, that variable or the GL renderer is not notified about the OpenGL context change. Solution proposal: - Move the current GL context cache into another place global.
J?rgen P. Tjern? d623c0b4 2014-06-04T09:59:10 SDL_opengl: Fix Mac build with new glext.h
J?rgen P. Tjern? defd90b6 2014-04-19T13:15:41 Render: Allow empty cliprect. This fixes an issue where an empty cliprect is treated the same as a NULL cliprect, causing the render backends to disable clipping. Also adds a new API, SDL_RenderIsClipEnabled(render) that allows you to differentiate between: - SDL_RenderSetClipRect(render, NULL) - SDL_Rect r = {0,0,0,0}; SDL_RenderSetClipRect(render, &r); Fixes https://bugzilla.libsdl.org/show_bug.cgi?id=2504
David Ludwig 3dcb451f 2014-04-09T21:29:19 Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.
Ryan C. Gordon 415675be 2014-03-20T11:14:44 Static analysis fix: division by zero.
Sam Lantinga a8f540fe 2014-03-09T22:48:38 Fixed renderer flags to include support for target textures after the renderer is created.
Gabriel Jacobo f61602b4 2014-02-27T20:21:46 Improve window recreation logic in OpenGL* renderers
Gabriel Jacobo 4c192bc8 2014-02-25T17:42:34 Fixes #2308, recreate window if GL requirements for the renderer are not met If the window has been created with values for SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_MAJOR_VERSION and SDL_GL_CONTEXT_MINOR_VERSION not matching those required by the renderer, attempt to recreate the window. This is needed on platforms where both GL and GLES 1/2 surfaces are supported by the video backend, requiring that the window be recreated when switching between context types.
Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
Sam Lantinga 8093cfd8 2013-11-15T22:07:35 Better fix for bug 2207 - SDL_RenderSetViewport behavior is different/incorrect on OpenGL renderer vs DirectX renderer At least, it works better here on my Mac. :)
Ryan C. Gordon 4f39f011 2013-11-15T23:20:50 Fix viewport being upside down in OpenGL renderer. Fixes Bugzilla #2207.
Sam Lantinga ef97aab9 2013-11-14T21:39:54 Backed out changeset 6c59f7c8ec17 - it didn't actually do anything useful
Sam Lantinga b36d98bd 2013-11-13T21:50:59 Diagonal flipping with RenderCopyEx Ivan Rubinson As it turns out, it was impossible to render a texture flipped diagonally (both vertically and horizontally) with one RenderCopyEx call. With help from #SDL @ freenode, we came up with a fix.
Sam Lantinga 1c9cc8c9 2013-11-05T21:01:25 Fixed performance regression caused by the fix for bug 2158
Sam Lantinga 20f5167d 2013-10-20T10:35:51 Use vertex arrays for drawing points in addition to lines
Sam Lantinga 82b8e6df 2013-10-20T10:10:14 Fixed bug 2158 - Pixel missing in SDL_RenderDrawLines Sean McKean I am running Ubuntu 12.04 (GL version 1.4 Mesa 8.0.4) , and on drawing a set of lines through the renderer through SDL_RenderDrawLines() (looped or not) or SDL_RenderDrawRect() I notice a pixel missing. For RenderDrawLines() it seems to be the second point in the sequence; for RenderDrawRect() it is the lower-right. This can be fixed by specifying SDL_RenderDrawPoint(s), but wouldn't it be easier to specify each pixel in a GL_POINTS glBegin/End loop in the OpenGL code, just to make sure? I also ran the same program on Android; the rendering seemed to be correct, which uses glDrawArrays.
Sam Lantinga 06cab857 2013-10-14T08:56:37 Added support for SDL_PIXELFORMAT_UYVY surfaces on Mac OS X
Sam Lantinga e5ef978e 2013-10-03T20:42:43 Fixed a potential double-free bug if glGenTextures() failed.
Sam Lantinga 57bd5147 2013-09-28T14:06:47 Added optimized YUV texture upload path with SDL_UpdateYUVTexture()
Edward Rudd 869a7076 2013-09-20T13:43:00 add in High DPI support (aka Retina) - based on J?rgen's patch with a few bug fixes
Sam Lantinga f79fc33a 2013-08-29T08:29:21 Christoph Mallon: Remove pointless if (x) before SDL_free(x)
Gabriel Jacobo 1e49b1ed 2013-08-21T09:47:10 OCD fixes: Adds a space after /* (glory to regular expressions!)
Gabriel Jacobo 695344d1 2013-08-21T09:43:09 OCD fixes: Adds a space before */
Gabriel Jacobo dad42067 2013-08-12T11:13:50 Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
