* Add support for OpenGL 3.2+ core profile contexts in QPainterJulian Thijssen2017-01-231-23/+79
| | | | | | | | | | | | | | | | | | | | | | | This change allows painting via QPainter onto a QOpenGLWindow, QOpenGLWidget or QOpenGLFramebufferObject when an core profile context is in use. This is important on macOS in particular, where compatibility profiles are not available, and so the only way to use modern OpenGL is via a core profile context. Added core profile compatible shaders with moder GLSL keywords. The paint engine binds a VAO and two VBOs from now on, whenever VAOs are supported. Note that this changes behavior also for OpenGL 2.x context that have VAO support via extensions. The Lancelot test suite gains support for core profile contexts. This can be triggered via -coreglbuffer in place of -glbuffer when manually inspecting via 'lance', while tst_lancelot will automatically run core context-based tests whenever supported.

* Add an OpenGL program binary disk cacheLaszlo Agocs2016-11-241-70/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a glProgramBinary-based disk cache in QOpenGLShaderProgram. By switching the typical program->addShaderFromSourceCode(QOpenGLShader::Vertex, ...) program->addShaderFromSourceCode(QOpenGLShader::Fragment, ...) invocations to program->addCacheableShaderFromSourceCode(QOpenGLShader::Vertex, ...) program->addCacheableShaderFromSourceCode(QOpenGLShader::Fragment, ...) the compilation may be skipped via gl(Get)ProgramBinary and a disk cache, when supported. Such QOpenGLShaderProgram instances will have no QOpenGLShader instances attached. Instead, the entire program binary (which is driver-specific) is loaded as-is. Support means OpenGL ES 3.0 or the presence of GL_ARB_get_program_binary, in combination with >= 1 supported binary formats. Note that some drivers claim program binary support but expose no formats. This amounts to no support in practice. When support is not present, calling the new functions is equivalent to the non-cacheable variants. If the OpenGL driver changes (vendor, renderer, version strings), recompilation and storage of the new, potentially incompatible binary program will happen transparently. The cache can always be disabled by setting QT_DISABLE_SHADER_DISK_CACHE=1 or the new application attribute Qt::AA_DisableShaderDiskCache. Location-wise the primary choice is the shared cache (GenericCacheLocation). If this is not available or is not writable, the per-process one (CacheLocation) is used instead. In addition to the new public APIs in QOpenGLShaderProgram, the main shader users in QtGui are migrated as well. (OpenGL paint engine, glyph cache, blitter, eglfs mouse cursor). This means that any application using QPainter on OpenGL or widgets with eglfs will benefit from the improved startup times. Qt Quick will follow suit as well. [ChangeLog][QtGui][OpenGL] QOpenGLShaderProgram offers a built-in program binary disk cache for systems with OpenGL ES 3.x or GL_ARB_get_program_binary. This can lead to significant increases in performance when it comes to application startup times for example. Usage is opt-in for direct C++ users of the class, however Qt's own main users of shaders, including Qt Quick and QPainter's OpenGL engine, are migrated to use the new, cache-enabled APIs. Opting out on application level is always possible via Qt::AA_DisableShaderDiskCache.

* QtBase: use printf-style qWarning/qDebug where possible (II)Marc Mutz2016-05-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The printf-style version of QDebug expands to a lot less code than the std::ostream-style version. Of course, you pay in type safety (but compilers warn about it these days), you cannot stream complex Qt types and streaming QStrings is awkward, but in many cases you actually improve on readability. But the main reason is that something that's not supposed to be executed under normal operation has no business bloating executable code size. This is not an attempt at converting all qWarnings() to printf-style, only the low-hanging fruit. In this second part, replace qWarning() << "" << non-QString with qWarning("..%.", non-QString). QString (and QUrl etc) have special escaping handling when streamed into QDebug, so leave those alone. They also seem to expand to less code than the qPrintable() alternative, so there's no reason to replace them. Saves 2KiB, 3.4KiB, ~750b and ~450b in text size in QtCore, Gui, Network and Widgets, resp., on optimized GCC 5.3 AMD64 builds.

* Use Q_UNLIKELY for every qFatal()/qCritical()Marc Mutz2015-11-291-7/+7
| | | | | | | | | | | | | | | | | | | | | If, after checking a condition, we issue a qFatal() or a qCritical(), by definition that check is unlikely to be true. Tell the compiler so it can move the error handling code out of the normal code path to increase the effective icache size. Moved conditional code around where possible so that we could always use Q_UNLIKELY, instead of having to revert to Q_LIKELY here and there. In some cases, simplified the expressions newly wrapped in Q_UNLIKELY as a drive-by.

* Dynamic GL: remove exporting symbolsLaszlo Agocs2014-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | Remove the opengl proxy for now. Later it will either be moved into a separate library or replaced by a QOpenGLFunctions-based approach. This means that the -opengl dynamic configuration is not usable for the time being. The rest of the enablers remain in place. The convenience function QOpenGLFunctions::isES() is now moved to QOpenGLContext and is changed to check the renderable type. This is extremely useful since besides supporting dynamic GL it solves also the problem of GL_ARB_ES2_compatibility (i.e. it triggers the real ES path when creating an ES-compatible context with a desktop OpenGL implementation).

* Dynamic GL switch on WindowsLaszlo Agocs2014-02-141-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch introduces a new build configuration on Windows which can be requested by passing -opengl dynamic to configure. Platforms other than Windows (including WinRT) are not affected. The existing Angle and desktop configurations are not affected. These continue to function as before and Angle remains the default. In the future, when all modules have added support for the dynamic path, as described below, the default configuration could be changed to be the dynamic one. This would allow providing a single set of binaries in the official builds instead of the current two. When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are never defined. Instead, the code path that has traditionally been desktop GL only becomes the dynamic path that has to do runtime checks. Qt modules and applications are not linked to opengl32.dll or libegl/glesv2.dll in this case. Instead, QtGui exports all necessary egl/egl/gl functions which will, under the hood, forward all requests to a dynamically loaded EGL/WGL/GL implementation. Porting guide (better said, changes needed to prepare your code to work with dynamic GL builds when the fallback to Angle is utilized): 1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to differentiate between desktop and ES where needed. Keep in mind that it is the desktop GL header (plus qopenglext.h) that is included, not the GLES one. QtGui's proxy will handle some differences, for example calling glClearDepth will route to glClearDepthf when needed. The built-in eglGetProcAddress is able to retrieve pointers for standard GLES2 functions too so code resolving OpenGL 2 functions will function in any case. 2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds, but never "angle" or "opengles2". 3. The preprocessor define QT_OPENGL_DYNAMIC is also available in dynamic builds. The usage of this is strongly discouraged and should not be needed anywhere except for QtGui and the platform plugin. 4. Code in need of the library handle can use QOpenGLFunctions::platformGLHandle(). The decision on which library to load is currently based on a simple test that creates a dummy window/context and tries to resolve an OpenGL 2 function. If this fails, it goes for Angle. This seems to work well on Win7 PCs for example that do not have proper graphics drivers providing OpenGL installed but are D3D9 capable using the default drivers. Setting QT_OPENGL to desktop or angle skips the test and forces usage of the given GL. There are also two new application attributes that could be used for the same purpose. If Angle is requested but the libraries are not present, desktop is tried. If desktop is requested, or if angle is requested but nothing works, the EGL/WGL functions will still be callable but will return 0. This conveniently means that eglInitialize() and such will report a failure. Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will tell which implementation is chosen. The textures example application is ported to OpenGL 2, the GL 1 code path is removed. [ChangeLog][QtGui] Qt builds on Windows can now be configured for dynamic loading of the OpenGL implementation. This can be requested by passing -opengl dynamic to configure. In this mode no modules will link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will dynamically choose between desktop and Angle during the first GL/EGL/WGL call. This allows deploying applications with a single set of Qt libraries with the ability of transparently falling back to Angle in case the opengl32.dll is not suitable, due to missing graphics drivers for example.
