-----------------------------------2.0------------------------------------- [18c2fa8] Fixed error reporting

  • Config::update() reports false on failing resource, independently of robustness
  • New function Config::getErrors() to get last errors
  • Error class is serializable and contains optional originator ID
  • Config::sendError() signature changed, originator is part of Error

[3458316] Fix #326: Remove Channel::getInput/OutputFrames

  • The input and output frames are now passed to frameAssemble and frameReadback, respectively.

[b2a92d4] Close #69: WindowSettings to decouple Window from SystemWindow

  • eq::fabric::Window::IATTR* are now eq::fabric::WindowSettings::IATTR*
  • eq::SystemWindow: ** need eq::NotifierInterface and eq::WindowSettings for construction ** remove getWindow(), getPipe(), getNode() and getConfig() ** add setter and getter for PixelViewport, name and sharedContextWindow
  • remove non-const getSharedContextWindow() from eq::Window
  • eq::WindowSystemIF::createWindow() needs eq::WindowSettings

[aa93fa8] Removed eqConfigTool which was superseeded by autoconfig

[c36ea6b] Close #237: Replace setError with error events

  • replace setError/getError with sendEvent and default Config::handleEvent implementation
  • FrameBufferObject, PixelBufferObject: ** remove setError/getError ** Incompatible return value change from bool to Error for FBO::init, FBO::resize, PBO::setup
  • Internal error events have an arbitrary number of std::string appended
  • add handleEvents() in Config::init and Config::update

[7890fa5] Remove deprecated functions:

  • eq::ConfigParams type. Use eq::fabric::ConfigParams.
  • eq::Frame::getData API. Use Frame::getFrameData.
  • WindowSystemEnum. Use WindowSystem( name ).
  • eq::COMMANDTYPE_EQ_CUSTOM. Use co::COMMANDTYPE_CUSTOM.
  • eq::fabric::Serializable type. Use co::Serializable.

[007e813] Remove deprecated window system types. Use their current counterpart in the eq::agl, eq::glx and eq::wgl namespaces. Moved XGetCurrentDisplay() and SetCurrentDisplay() from the eq to the eq::glx namespace.

[Collage 5bb65c6] Remove most legacy EQ_ defines. Use lunchbox namespace for co::base and co::Global.

[Collage 6f82b69] Remove legacy EQ_ macros: EQ_STDEXT_NAMESPACE_OPEN EQ_STDEXT_NAMESPACE_CLOSE EQ_MIN EQ_MAX EQ_MAX_UINT32 EQ_BIT1 EQ_BIT2 EQ_BIT3 EQ_BIT4 EQ_BIT5 EQ_BIT6 EQ_BIT7 EQ_BIT8 EQ_BIT9 EQ_BIT10 EQ_BIT11 EQ_BIT12 EQ_BIT13 EQ_BIT14 EQ_BIT15 EQ_BIT16 EQ_BIT17 EQ_BIT18 EQ_BIT19 EQ_BIT20 EQ_BIT21 EQ_BIT22 EQ_BIT23 EQ_BIT24 EQ_BIT25 EQ_BIT26 EQ_BIT27 EQ_BIT28 EQ_BIT29 EQ_BIT30 EQ_BIT31 EQ_BIT32 EQ_BIT33 EQ_BIT34 EQ_BIT35 EQ_BIT36 EQ_BIT37 EQ_BIT38 EQ_BIT39 EQ_BIT40 EQ_BIT41 EQ_BIT42 EQ_BIT43 EQ_BIT44 EQ_BIT45 EQ_BIT46 EQ_BIT47 EQ_BIT48 EQ_BIT_ALL_32 EQ_BIT_ALL_64 EQ_BIT_NONE EQ_TS_VAR EQ_TS_SCOPED EQ_TS_RESET EQ_TS_THREAD EQ_TS_NOT_THREAD EQ_ALIGN8 EQ_ALIGN16 EQ_TIMEOUT_INDEFINITE EQ_TIMEOUT_DEFAULT EQ_DLLIMPORT EQ_DLLEXPORT EQ_UNDEFINED_UINT32 EQ_GCC_4_0_OR_LATER EQ_GCC_4_1_OR_LATER EQ_GCC_4_2_OR_LATER EQ_GCC_4_3_OR_LATER EQ_GCC_4_4_OR_LATER EQ_GCC_4_5_OR_LATER EQ_GCC_4_6_OR_LATER EQ_GCC_4_7_OR_LATER EQ_GCC_4_8_OR_LATER EQ_GCC_4_9_OR_LATER EQ_1KB EQ_10KB EQ_100KB EQ_1MB EQ_10MB EQ_100MB EQ_16KB EQ_32KB EQ_64KB EQ_128KB EQ_48MB EQ_64MB EQ_ASSERT EQ_ASSERTINFO EQ_ERROR EQ_WARN EQ_INFO EQ_VERB EQ_CHECK EQ_UNIMPLEMENTED EQ_UNREACHABLE EQ_DONTCALL EQ_ABORT EQ_LOG EQ_SAFECAST: Replace EQ_ with LB_

[6ee6727] Simplify ObjectManager and BitmapFont APIs:

  • Replace template key type by 'void *' which was used exclusively
  • Use ObjectManager references instead of pointers throughout API
  • Needed for #83

To port, replace:

  • eq::Window::ObjectManager* -> eq::util::ObjectManager&
  • eq::Window::Font* -> eq::util::BitmapFont*

-----------------------------------1.6-------------------------------------

03/Dec/2012 Remove ..., fabric::View::getEqualizer()(::getTileSize( ))

07/Sep/2012 Removed COMMANDTYPE_EQ_CUSTOM. Use co::COMMANDTYPE_CUSTOM instead.

06/Sep/2012 New API in eq::Config & seq::ViewData for event handling. sendEvent() & handleEvent() have changed signatures, getNextEvent() supersedes tryNextEvent() & nextEvent().

eq::ConfigEvent is replaced by EventOCommand for sending and by eq::EventICommand for receiving events. Old API is deprecated and will be removed in version 2.0.

31/Jul/2012 Moved ErrorRegistry from Collage to eq::fabric. Use eq::fabric::Global::getErrorRegistry().

Removed co::DataIStream::advanceBuffer. New parameter for co::DataIStream::getRemainingBuffer() does advance buffer now.

27/Jul/2012 Made co::DataIStream::read private. Use 'is >> co::Array< T >( ptr, num )' instead.

-----------------------------------1.4-------------------------------------

-----------------------------------1.2-------------------------------------

25/Oct/2011 Removed co::Object::commitNB and commitSync since request is no longer dispatched to command thread. Use commit instead.

17/Jul/2011 Moved installed client headers to eq/client. Applications should always use <eq/eq.h> instead of individual headers.

03/Jun/2011 Added a return value and timeout to co::LocalNode::acquireSendToken(), see method documentation.

29/Mar/2011 Changed uint32_t eq::Version::getRevision(); to: std::string eq::Version::getRevision();

-----------------------------------1.0-------------------------------------

14/Mar/2011 Changed object mapping behavior when using a concrete version from: If the requested version does no longer exist, mapObject() will fail. to: If a concrete requested version no longer exists, mapObject() will map the oldest available version.

Moved include/GL to include/eq/GL. Use '#include <eq/gl.h>' to include OpenGL headers only.

10/Mar/2011 Do not include window system headers by default to avoid global namespace pollution. Define EQ_SYSTEM_INCLUDES before including eq/eq.h to get previous definitions.

01/Mar/2011 Added new 'incarnation' parameter to co::Object::commit, with a default parameter selecting the previous behavior for commit wrt auto obsoletion. co::Object::commitNB has the same new parameter, with no default value.

--------------------------------1.0 beta-----------------------------------

10/Feb/2011 Changed GLXWindow implementation to use GLXFBConfigs. Use GLXFBConfigs in place of XVisualInfo for the appropriate GLXWindow methods.

14/Jan/2011 libEqualizer links libCollage dynamically, not statically. All libraries use correct versioning as mandated by the operating system.

-------------------------------1.0 alpha-----------------------------------

7/Jan/2011 Rename EVENT_POINTER_* to differantiate channel and window pointer events.

 CHANNEL_POINTER_MOTION         // = POINTER_MOTION
 CHANNEL_POINTER_BUTTON_PRESS   // = POINTER_BUTTON_PRESS
 CHANNEL_POINTER_BUTTON_RELEASE // = POINTER_BUTTON_RELEASE
 WINDOW_POINTER_WHEEL           // = POINTER_WHEEL
 WINDOW_POINTER_MOTION
 WINDOW_POINTER_BUTTON_PRESS
 WINDOW_POINTER_BUTTON_RELEASE

replaces POINTER_MOTION POINTER_BUTTON_PRESS POINTER_BUTTON_RELEASE POINTER_WHEEL

20/Dec/2010 Renamed the eq::net namespace to co(llage). Change all prefixes from eq::net to co.

14/Dec/2010 Removed net::Session. Use net::LocalNode or eq::Config of object registration and mapping. The latter retains buffered object data for mapping up to latency frames.

29/Nov/2010 No automatic listener connections are created for the application node. Existing multi-node configs will fail if they do not configure a listener. AppNode listeners can be added either by specifying them in the configuration filem by using the --eq-listen command line option or programmatically by adding connection descriptions before Client::initLocal().

Image::setAlphaUsage Image::getAlphaUsage Image::upload( buffer, texture, position, objectManager ) replaces Image::enableAlphaUsage Image::disableAlphaUsage Image::ignoreAlpha Image::upload( buffer, position, objectManager ) Image::upload( buffer, texture, objectManager )

Image::hasData is removed

22/Nov/2010 Replace object identifiers with UUIDs Replace defines EQ_ID_INVALID with the new type by UUID::ZERO for object identifiers Removed defines EQ_ID_MAX, NONE, INVALID, ANY for object identifiers Replace object versions with uint128_t Master versions have always 0 for the 64bit high value

change frameID type to uint128_t for methods: frameReadback, frameAssemble, frameDraw, frameClear, frameStart, startFrame, frameViewStart, frameViewFinish, frameFinish, frameDrawFinish, frameTasksFinish in the classes window, channel, pipe, node and config.

change initID type to uint128_t for configInit in pipe, window, channel and config

bool Pipe::configInitSystemPipe( const uint128_t& initID ); bool Window::configInitSystemWindow( const eq::uint128_t& initID ); bool Window::configInitGL( const eq::uint128_t& initID ); bool Session::mapObject( Object* object, const base::UUID& id, const uint128_t& version = VERSION_OLDEST ); uint32_t Session::mapObjectNB( Object* object, const base::UUID& id, const uint128_t& version = VERSION_OLDEST ); void Object::notifyNewHeadVersion( const uint128_t& version ); uint128_t Object::getOldestVersion() const; uint128_t Object::getVersion() const; uint128_t Object::getHeadVersion() const; uint128_t Object::sync( const uint128_t& version = VERSION_HEAD ); uint128_t Object::commit(); uint128_t Object::commitSync( const uint32_t commitID ); base::UUID Object::getID() const replaces bool Pipe::configInitSystemPipe( const uint32_t initID ); bool Window::configInitSystemWindow( const uint32_t initID ); bool Window::configInitGL( const uint32_t initID ); bool Session::mapObject( Object* object, const uint32_t id, const uint128_t& version = VERSION_OLDEST ); uint32_t Session::mapObjectNB( Object* object, const uint32_t id, const uint128_t& version = VERSION_OLDEST ); void Object::notifyNewHeadVersion( const uint32_t version ); uint32_t Object::getOldestVersion() const; uint32_t Object::getVersion() const; uint32_t Object::getHeadVersion() const; uint32_t Object::sync( const uint32_t version = VERSION_HEAD ); uint32_t Object::commit(); uint32_t Object::commitSync( const uint32_t commitID ); uint32_t Object::getID() const

19/Nov/2010 The GLXEventHandler is new per-window. Event handler init/exit has been moved from GLXPipe to GLXWindow and the GLXEventHandler API has changed accordingly.

15/Nov/2010 Statistic::CHANNEL_FRAME_WAIT_READY replaces Statistic::CHANNEL_WAIT_FRAME

02/Nov/2010 void fabric::Object::setError( const int32_t error ) base::Error fabric::Object::getError() const replace void fabric::Object::setErrorMessage( const std::string& error ) const std::string& fabric::Object::getErrorMessage() const

29/Oct/2010 void FrameData::setZoom( const Zoom& zoom ); const Zoom& FrameData::getZoom() const; replaces void Frame::setInputZoom( const Zoom& zoom ); const Zoom& Frame::getInputZoom() const;

25/Oct/2010 Error util::FrameBufferObject::getError() const; Error ComputeContext::getError() const; void ComputeContext::setError( const uint32_t error ); replaces const std::string& util::FrameBufferObject::getErrorMessage() const; const std::string& ComputeContext::getErrorMessage() const; void ComputeContext::setErrorMessage( const std::string& errorMessage );

20/Oct/2010 void PluginRegistry::addDirectory( const std::string& path ); void PluginRegistry::removeDirectory( const std::string& path ); const Strings& PluginRegistry::getDirectories() const; replaces const Strings& Global::getPluginDirectories(); static void Global::addPluginDirectory( const std::string& static void Global::removePluginDirectory( const std::string& path );
