It can be reproduced by calling the test as: *    ./networking-QtNetworkTests httpsRequestNoSSLVersion * * This test may get stuck on some systems. Running the full suite, or: *    ./networking-QtNetworkTests httpsRequestNoSSLVersion * * will work correctly because  QSslSocket::sslLibraryVersionString() initializes something. */const QUrl HTTP_URL("http://ping.archlinux.org/");const QUrl HTTPS_URL("https://ping.archlinux.org/");const QString TCP_HOST("ping.archlinux.org");const QString SSL_HOST("ping.archlinux.org");   QTEST_MAIN(QtNetworkTests); void QtNetworkTests::initTestCase() {    qDebug() << "Init";    qRegisterMetaType<QNetworkReply*>(); } void QtNetworkTests::tcpSocket() {    QTcpSocket sock;    QSignalSpy spy(&sock, &QTcpSocket::connected);     qDebug() << "Connecting to" << TCP_HOST << "on port 80";    sock.connectToHost(TCP_HOST, 80);    spy.wait();    QVERIFY(sock.waitForConnected());    QVERIFY(sock.localPort() > 0);     qDebug() << "Local address is" << sock.localAddress()  << ":" << sock.localPort();} void QtNetworkTests::sslSocket() {    QSslSocket sock;    QSignalSpy spy(&sock, &QSslSocket::connected);     QVERIFY(QSslSocket::supportsSsl());    qDebug() << "SSL library version: " << QSslSocket::sslLibraryVersionString();     qDebug() << "Connecting to" << SSL_HOST << "on port 443";    sock.connectToHostEncrypted(SSL_HOST, 443);    spy.wait();    QVERIFY(sock.waitForEncrypted());    QVERIFY(sock.localPort() > 0);     QVERIFY(!sock.sslConfiguration().isNull());    QVERIFY(sock.sslHandshakeErrors().length() == 0);    QVERIFY(sock.sessionProtocol() != QSsl::UnknownProtocol);     qDebug() << "Local address is" << sock.localAddress()  << ":" << sock.localPort();    qDebug() << "SSL protocol : " << sock.sessionProtocol();    qDebug() << "SSL cipher   : " << sock.sessionCipher().protocolString();    qDebug() << "SSL cert     : " << sock.peerCertificate();}  void QtNetworkTests::httpRequest() {    auto manager = new QNetworkAccessManager();     qDebug() << "Making request to" << HTTP_URL;    QSignalSpy spy(manager, &QNetworkAccessManager::finished);    QNetworkRequest req(HTTP_URL);    manager->get(req);     spy.wait();     QCOMPARE(spy.count(), 1);    QList<QVariant> arguments = spy.takeFirst();    QNetworkReply *reply = arguments.at(0).value<QNetworkReply*>();    QVERIFY(!reply->error());    QVERIFY(!reply->sslConfiguration().isNull());     QString data = reply->readAll();    qDebug() << "DATA: " << data;}  // Unlike the test below this works, because the sslLibraryVersionString call pokes something// in the Qt guts to make things initialize properly. void QtNetworkTests::httpsRequest() {    auto manager = new QNetworkAccessManager();     qDebug() << "SSL library version      : " << QSslSocket::sslLibraryVersionString();    qDebug() << "SSL library version      : " << QSslSocket::sslLibraryVersionString();    qDebug() << "SSL library build version: " << QSslSocket::sslLibraryBuildVersionString();      qDebug() << "Making request to" << HTTPS_URL;    QSignalSpy spy(manager, &QNetworkAccessManager::finished);    QNetworkRequest req(HTTPS_URL);    manager->get(req);     spy.wait();     QCOMPARE(spy.count(), 1);    QList<QVariant> arguments = spy.takeFirst();    QNetworkReply *reply = arguments.at(0).value<QNetworkReply*>();    QVERIFY(!reply->error());    QVERIFY(!reply->sslConfiguration().isNull());    qDebug() << "Peer cert:" << reply->sslConfiguration().peerCertificate();    QString data = reply->readAll();    qDebug() << "DATA: " << data;    qDebug() << "SSL library version: " << QSslSocket::sslLibraryVersionString(); }  // On some systems, this hangs forever.
