Detailed Description

This class is responsible receiving the request and sending the response. It must be reimplemented by real HTTP engines due some pure virtual methods.

The subclass must create an Engine per thread (worker core), if the Application passed to the constructor has a worker core greater than 0 it will issue a new Application instance, failing to do so a fatal error is generated (usually indicating that the Application does not have a Q_INVOKABLE constructor).

Definition at line 33 of file engine.h.

Constructor & Destructor Documentation

Engine::Engine	(	Cutelyst::Application *	app,
		int	workerCore,
		const QVariantMap &	opts
	)

explicit

Constructs an Engine object, where app is the application that might be used to create new instances if workerCore is greater than 1, opts is the options loaded by the engine subclass.

Parameters

app	The application loaded
workerCore	The thread number
opts	The configuation options

Definition at line 57 of file engine.cpp.

References app(), QObject::connect(), QObject::metaObject(), QMetaObject::newInstance(), opts(), processRequest(), processRequestAsync(), QObject::setParent(), and workerCore().

Returns: the Application object we are dealing with

static void Cutelyst::Engine::camelCaseByteArrayHeader ( QByteArray & key )

inlinestatic

Convert Header key to camel case

Definition at line 139 of file engine.h.

static QString Cutelyst::Engine::camelCaseHeader ( const QString & headerKey )

inlinestatic

Returns the header key in camel case form

QVariantMap Engine::config ( const QString & entity ) const

Parameters

entity the entity you are interested in

Returns: the configuration settings

Headers & Engine::defaultHeaders ( )

protected

This is the HTTP default response headers that each request gets

Definition at line 302 of file engine.cpp.

const char * Engine::httpStatusMessage	(	quint16	status,
		int *	len = `nullptr`
	)

static

Returns the HTTP status message for the given status.

Definition at line 161 of file engine.cpp.

References QByteArray::number().

bool Engine::initApplication ( )

protected

This method inits the application and calls init on the engine. It must be called on the engine's thread

Returns: true if succeded

Definition at line 125 of file engine.cpp.

References QThread::currentThread(), and QObject::thread().

bool Cutelyst::Engine::isZeroWorker ( ) const

inline

Returns true if this is the Zero worker, ie if workerId() == 0 and workerCore() == 0

Note: the value returned from this function is only valid when postFork() is issued.

Definition at line 217 of file engine.h.

QVariantMap Engine::loadIniConfig ( const QString & filename )

static

Returns a QVariantMap with the INI parsed from filename.

Definition at line 332 of file engine.cpp.

References QSettings::beginGroup(), QSettings::childGroups(), QSettings::childKeys(), QSettings::endGroup(), QList::insert(), QSettings::status(), and QSettings::value().

QVariantMap Engine::loadJsonConfig ( const QString & filename )

static

Returns a QVariantMap with the JSON parsed from filename.

Definition at line 356 of file engine.cpp.

References QJsonDocument::fromJson(), QFile::open(), QIODevice::readAll(), QVariant::toMap(), and QJsonDocument::toVariant().

QVariantMap Engine::opts ( ) const

Engine options

Definition at line 314 of file engine.cpp.

Referenced by Engine().

bool Engine::postForkApplication ( )

protected

Subclasses must be call after the engine forks by the worker thread, if no forking is involved it must be called once the worker thread has started.

For convenience QThread::currentThread() has it's object name set with the worker core number.

Returns: true if the engine should use this process

Definition at line 142 of file engine.cpp.

References QThread::currentThread(), QString::number(), and QObject::setObjectName().

void Engine::processRequest ( EngineRequest * request )

Process the EngineRequest req, the caller must delete the context when the request is finished.

This method allows for engines to keep the Context alive while processing websocket data.

Definition at line 308 of file engine.cpp.

Referenced by Engine().

void Cutelyst::Engine::processRequestAsync ( Cutelyst::EngineRequest * request )

signal

Process the EngineRequest req Async, the caller must delete the context when the request is finished.

This method allows for engines to keep the Context alive while processing websocket data.

Referenced by Engine().

void Engine::setConfig ( const QVariantMap & config )

Sets the configuration to be used by Application

Definition at line 326 of file engine.cpp.

References config().

quint64 Engine::time ( )

virtual

Returns: current micro seconds time to be used for stats, the default implementation returns QDateTime::currentMSecsSinceEpoch() * 1000, to become micro seconds, so if the engine supports a more precise value it can reimplement this method.

Definition at line 156 of file engine.cpp.

References QDateTime::currentMSecsSinceEpoch().

int Engine::workerCore ( ) const

Returns the worker core set when constructing the engine

Returns: the worker core (thread)

Definition at line 119 of file engine.cpp.

Referenced by Engine(), and Cutelyst::Application::setup().

int Engine::workerId ( ) const

pure virtual

Reimplement this to get the workerId of the engine subclass, this is the same as processes id.

Note: the value returned from this function is only valid when postFork() is issued.

Returns: the worker id (process)
