This patch allows the client implementation to react to specific getRequests, such as folder checks, etc. It allows to connect client-specific slots to requests, catch its errors and handle them separately. I need this patch to be able to check more than one remote folder on the server, and not mix up their job's signal handling.

The Qt HTTP thread calls authenticationRequired (indirectly) using a BlockingQueuedConnection. So when we call invalidateToken from slot connected to this signal and end up calling QNAM::clearAccessCache which waits on the thread for 5 seconds Backtraces: Qt HTTP thread: #0 0x00007ffff20c707f in pthread_cond_wait@@GLIBC_2.3.2 () #1 0x00007ffff43f0c0b in QWaitConditionPrivate::wait #2 QWaitCondition::wait #3 0x00007ffff43ea06b in QSemaphore::acquire #4 0x00007ffff45dcf6f in QMetaObject::activate [...] #9 0x00007ffff45dd607 in QMetaObject::activate #10 0x00007ffff4edbaf7 in QHttpNetworkReply::authenticationRequired #11 0x00007ffff4e0b2b4 in QHttpNetworkConnectionPrivate::handleAuthenticateChallenge #12 0x00007ffff4e10753 in QHttpNetworkConnectionChannel::handleStatus #13 0x00007ffff4e11cc9 in QHttpNetworkConnectionChannel::allDone #14 0x00007ffff4e14605 in QHttpProtocolHandler::_q_receiveReply Main Thread: #0 0x00007ffff20c7428 in pthread_cond_timedwait@@GLIBC_2.3.2 () #1 0x00007ffff43f0b56 in QWaitConditionPrivate::wait_relative (time=5000, this=0x136c580) #2 QWaitConditionPrivate::wait (time=5000, this=0x136c580) #3 QWaitCondition::wait (this=this@entry=0x136c788, mutex=mutex@entry=0x136c760, time=time@entry=5000) #4 0x00007ffff43efa6e in QThread::wait (this=<optimized out>, time=time@entry=5000) #5 0x00007ffff4e1edd3 in QNetworkAccessManagerPrivate::clearCache #6 0x00007ffff7b6fb03 in OCC::HttpCredentials::invalidateToken() #7 0x000000000057adb4 in OCC::AccountState::slotInvalidCredentials() #8 0x000000000057ac76 in OCC::AccountState::slotConnectionValidatorResult(OCC::ConnectionValidator::Status, QStringList const&) () #9 0x00000000005ab45c in OCC::AccountState::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) #10 0x00007ffff45dcd30 in QMetaObject::activate #11 0x00007ffff7b78671 in OCC::ConnectionValidator::connectionResult(OCC::ConnectionValidator::Status, QStringList) () #12 0x00007ffff7ae2514 in OCC::ConnectionValidator::reportResult(OCC::ConnectionValidator::Status) () #13 0x00007ffff7ae39b7 in OCC::ConnectionValidator::slotAuthFailed(QNetworkReply*) () #14 0x00007ffff7b784a9 in OCC::ConnectionValidator::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #15 0x00007ffff45dcd30 in QMetaObject::activate #16 0x00007ffff7b766dc in OCC::AbstractNetworkJob::networkError(QNetworkReply*) #17 0x00007ffff7af9f6e in OCC::AbstractNetworkJob::slotFinished() #18 0x00007ffff7b7654d in OCC::AbstractNetworkJob::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #20 0x00007ffff45dd607 in QMetaObject::activate #21 0x00007ffff4edd143 in QNetworkReply::finished #22 0x00007ffff4e3fec7 in QNetworkReplyHttpImplPrivate::finished #23 0x00007ffff4e41818 in QNetworkReplyHttpImpl::close #24 0x00007ffff7b7047b in OCC::HttpCredentials::slotAuthentication(QNetworkReply*, QAuthenticator*) () #25 0x00007ffff7b79092 in OCC::HttpCredentials::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #27 0x00007ffff45dd607 in QMetaObject::activate #28 0x00007ffff4e1d6fb in QNetworkAccessManager::authenticationRequired #29 0x00007ffff4e1ea07 in QNetworkAccessManagerPrivate::authenticationRequired #30 0x00007ffff4e3c784 in QNetworkReplyHttpImplPrivate::httpAuthenticationRequired Another case of Main Thread: #5 0x00007ffff4e1edd3 in QNetworkAccessManagerPrivate::clearCache #6 0x00007ffff7b6fb03 in OCC::HttpCredentials::invalidateToken() #7 0x000000000057b1e4 in OCC::AccountState::slotInvalidCredentials() () #8 0x00000000005abb8a in OCC::AccountState::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #9 0x00007ffff45dcd30 in QMetaObject::activate #10 0x00007ffff7b76ed5 in OCC::Account::invalidCredentials() () #11 0x00007ffff7ad55f5 in OCC::Account::handleInvalidCredentials() #12 0x00007ffff7afa69a in OCC::AbstractNetworkJob::slotFinished() #13 0x00007ffff7b7654d in OCC::AbstractNetworkJob::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #15 0x00007ffff45dd607 in QMetaObject::activate #16 0x00007ffff4edd143 in QNetworkReply::finished #17 0x00007ffff4e3fec7 in QNetworkReplyHttpImplPrivate::finished #18 0x00007ffff4e41818 in QNetworkReplyHttpImpl::close #19 0x00007ffff7b7047b in OCC::HttpCredentials::slotAuthentication(QNetworkReply*, QAuthenticator*) () #20 0x00007ffff7b79092 in OCC::HttpCredentials::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #22 0x00007ffff45dd607 in QMetaObject::activate #23 0x00007ffff4e1d6fb in QNetworkAccessManager::authenticationRequired
