81 \section1 Introduction -

82 -

83 OpenGL programming can be very error prone. Most of the time, a single -

84 failing call to OpenGL can cause an entire portion of an application to -

85 stop working, with nothing being drawn on the screen. -

86 -

87 The only way to be sure that no errors are being returned from the OpenGL -

88 implementation is checking with \c{glGetError} after each and every API -

89 call. Moreover, OpenGL errors stack up, therefore glGetError should always -

90 be used in a loop like this: -

91 -

92 \code -

93 -

94 GLenum error = GL_NO_ERROR; -

95 do { -

96 error = glGetError(); -

97 if (error != GL_NO_ERROR) -

98 // handle the error -

99 } while (error != GL_NO_ERROR); -

100 -

101 \endcode -

102 -

103 There are also many other information we are interested in (as application -

104 developers), for instance performance issues, or warnings about using -

105 deprecated APIs. Those kind of messages are not reported through the -

106 ordinary OpenGL error reporting mechanisms. -

107 -

108 QOpenGLDebugLogger aims at addressing these issues by providing access to -

109 the \e{OpenGL debug log}. If your OpenGL implementation supports it (by -

110 exposing the \c{GL_KHR_debug} extension), messages from the OpenGL server -

111 will be either logged in an internal OpenGL log, or passed in "real-time" -

112 to listeners as they're generated from OpenGL. -

113 -

114 QOpenGLDebugLogger supports both these modes of operation. Refer to the -

115 following sections to find out the differences between them. -

116 -

117 \section1 Creating an OpenGL Debug Context -

118 -

119 For efficiency reasons, OpenGL implementations are allowed not to create -

120 any debug output at all, unless the OpenGL context is a debug context. In order -

121 to create a debug context from Qt, you must set the QSurfaceFormat::DebugContext -

122 format option on the QSurfaceFormat used to create the QOpenGLContext object: -

123 -

124 \code -

125 -

126 QSurfaceFormat format; -

127 // asks for a OpenGL 3.2 debug context using the Core profile -

128 format.setMajorVersion(3); -

129 format.setMinorVersion(2); -

130 format.setProfile(QSurfaceFormat::CoreProfile); -

131 format.setOption(QSurfaceFormat::DebugContext); -

132 -

133 QOpenGLContext *context = new QOpenGLContext; -

134 context->setFormat(format); -

135 context->create(); -

136 -

137 \endcode -

138 -

139 Note that requesting a 3.2 OpenGL Core Profile is just for the example's -

140 purposes; this class is not tied to any specific OpenGL or OpenGL ES -

141 version, as it relies on the availability of the \c{GL_KHR_debug} extension -

142 (see below). -

143 -

144 \section1 Creating and Initializing a QOpenGLDebugLogger -

145 -

146 QOpenGLDebugLogger is a simple QObject-derived class. Just like all QObject -

147 subclasses, you create an instance (and optionally specify a parent -

148 object), and like the other OpenGL functions in Qt you \e{must} initialize -

149 it before usage by calling initialize() whilst there is a current OpenGL context: -

150 -

151 \code -

152 -

153 QOpenGLContext *ctx = QOpenGLContext::currentContext(); -

154 QOpenGLDebugLogger *logger = new QOpenGLDebugLogger(this); -

155 -

156 logger->initialize(); // initializes in the current context, i.e. ctx -

157 -

158 \endcode -

159 -

160 Note that the \c{GL_KHR_debug} extension \e{must} be available in the context -

161 in order to access the messages logged by OpenGL. You can check the -

162 presence of this extension by calling: -

163 -

164 \code -

165 -

166 ctx->hasExtension(QByteArrayLiteral("GL_KHR_debug")) -

167 -

168 \endcode -

169 -

170 where \c{ctx} is a valid QOpenGLContext. If the extension is not available, -

171 initialize() will return false. -

172 -

173 \section1 Reading the Internal OpenGL Debug Log -

174 -

175 OpenGL implementations keep an internal log of debug messages. Messages -

176 stored in this log can be retrieved by using the loggedMessages() function: -

177 -

178 \code -

179 -

180 const QList<QOpenGLDebugMessage> messages = logger->loggedMessages(); -

181 for (const QOpenGLDebugMessage &message : messages) -

182 qDebug() << message; -

183 -

184 \endcode -

185 -

186 The internal log has a limited size; when it fills up, older messages will -

187 get discarded to make room for the new incoming messages. When you call -

188 loggedMessages(), the internal log will be emptied as well. -

189 -

190 If you want to be sure not to lose any debug message, you must use real-time -

191 logging instead of calling this function. However, debug messages might -

192 still be generated in the timespan between context creation and activation -

193 of real-time logging (or, in general, when the real-time logging is disabled). -

194 -

195 \section1 Real-time logging of messages -

196 -

197 It is also possible to receive a stream of debug messages from the OpenGL -

198 server \e{as they are generated} by the implementation. In order to do so, -

199 you need to connect a suitable slot to the messageLogged() signal, and -

200 start logging by calling startLogging(): -

201 -

202 \code -

203 -

204 connect(logger, &QOpenGLDebugLogger::messageLogged, receiver, &LogHandler::handleLoggedMessage); -

205 logger->startLogging(); -

206 -

207 \endcode -

208 -

209 Similarly, logging can be disabled at any time by calling the stopLogging() -

210 function. -

211 -

212 Real-time logging can be either asynchronous or synchronous, depending on -

213 the parameter passed to startLogging(). When logging in asynchronous mode -

214 (the default, as it has a very small overhead), the OpenGL implementation -

215 can generate messages at any time, and/or in an order which is different from the -

216 order of the OpenGL commands which caused those messages to be logged. -

217 The messages could also be generated from a thread that it's different from -

218 the thread the context is currently bound to. This is because OpenGL -

219 implementations are usually highly threaded and asynchronous, and therefore -

220 no warranties are made about the relative order and the timings of the -

221 debug messages. -

222 -

223 On the other hand, logging in synchronous mode has a high overhead, but -

224 the OpenGL implementation guarantees that all the messages caused by a -

225 certain command are received in order, before the command returns, -

226 and from the same thread the OpenGL context is bound to. -

227 -

228 This means that when logging in synchronous mode you will be able to run -

229 your OpenGL application in a debugger, put a breakpoint on a slot connected -

230 to the messageLogged() signal, and see in the backtrace the exact call -

231 that caused the logged message. This can be extremely useful to debug -

232 an OpenGL problem. Note that if OpenGL rendering is happening in another -

233 thread, you must force the signal/slot connection type to Qt::DirectConnection -

234 in order to be able to see the actual backtrace. -

235 -

236 Refer to the LoggingMode enum documentation for more information about -

237 logging modes. -

238 -

239 \note When real-time logging is enabled, debug messages will \e{not} be -

240 inserted in the internal OpenGL debug log any more; messages already -

241 present in the internal log will not be deleted, nor they will be emitted -

242 through the messageLogged() signal. Since some messages might be generated -

243 before real-time logging is started (and therefore be kept in the internal -

244 OpenGL log), it is important to always check if it contains any message -

245 after calling startLogging(). -

246 -

247 \section1 Inserting Messages in the Debug Log -

248 -

249 It is possible for applications and libraries to insert custom messages in -

250 the debug log, for instance for marking a group of related OpenGL commands -

251 and therefore being then able to identify eventual messages coming from them. -

252 -

253 In order to do so, you can create a QOpenGLDebugMessage object by calling -

254 \l{QOpenGLDebugMessage::}{createApplicationMessage()} or -

255 \l{QOpenGLDebugMessage::}{createThirdPartyMessage()}, and then inserting it -

256 into the log by calling logMessage(): -

257 -

258 \code -

259 -

260 QOpenGLDebugMessage message = -

261 QOpenGLDebugMessage::createApplicationMessage(QStringLiteral("Custom message")); -

262 -

263 logger->logMessage(message); -

264 -

265 \endcode -

266 -

267 Note that OpenGL implementations have a vendor-specific limit to the length -

268 of the messages that can be inserted in the debug log. You can retrieve -

269 this length by calling the maximumMessageLength() method; messages longer -

270 than the limit will automatically get truncated. -

271 -

272 \section1 Controlling the Debug Output -

273 -

274 QOpenGLDebugMessage is also able to apply filters to the debug messages, and -

275 therefore limit the amount of messages logged. You can enable or disable -

276 logging of messages by calling enableMessages() and disableMessages() -

277 respectively. By default, all messages are logged. -

278 -

279 It is possible to enable or disable messages by selecting them by: -

280 -

281 \list -

282 \li source, type and severity (and including all ids in the selection); -

283 \li id, source and type (and including all severities in the selection). -

284 \endlist -

285 -

286 Note that the "enabled" status for a given message is a property of the -

287 (id, source, type, severity) tuple; the message attributes \e{do not} form -

288 a hierarchy of any kind. You should be careful about the order of the calls -

289 to enableMessages() and disableMessages(), as it will change which -

290 messages will are enabled / disabled. -

291 -

292 It's not possible to filter by the message text itself; applications -

293 have to do that on their own (in slots connected to the messageLogged() -

294 signal, or after fetching the messages in the internal debug log -

295 through loggedMessages()). -

296 -

297 In order to simplify the management of the enabled / disabled statuses, -

298 QOpenGLDebugMessage also supports the concept of \c{debug groups}. A debug -

299 group contains the group of enabled / disabled configurations of debug -

300 messages. Moreover, debug groups are organized in a stack: it is possible -

301 to push and pop groups by calling pushGroup() and popGroup() respectively. -

302 (When an OpenGL context is created, there is already a group in the stack). -

303 -

304 The enableMessages() and disableMessages() functions will modify the -

305 configuration in the current debug group, that is, the one at the top of -

306 the debug groups stack. -

307 -

308 When a new group is pushed onto the debug groups stack, it will inherit -

309 the configuration of the group that was previously on the top of the stack. -

310 Vice versa, popping a debug group will restore the configuration of -

311 the debug group that becomes the new top. -

312 -

313 Pushing (respectively popping) debug groups will also automatically generate -

314 a debug message of type QOpenGLDebugMessage::GroupPushType (respectively -

315 \l{QOpenGLDebugMessage::}{GroupPopType}). -
