File 0001-Fix-PackageKit-not-emitting-network-state-changed-signal.patch of Package PackageKit-Qt
From 9652f94119523ab1125b3be435c367913e18869b Mon Sep 17 00:00:00 2001 From: Antonio Larrosa <alarrosa@suse.com> Date: Mon, 18 Mar 2019 16:00:39 +0100 Subject: [PATCH] Fix PackageKit not emitting network state changed signal when stopped PackageKit can be configured to shutdown automatically after x seconds of inactivity. If a computer doesn't have a network connection and PackageKit is shut down (for example because a laptop user takes too long to enter the wifi password) then PackageKit never emits the properties changed signal (it can't since it's not running) so PackageKit-Qt never emits the networkStateChanged signal and applications like the plasma pk update applet never updates its status. With this commit, a NetworkManagerMonitor class is added that connects directly to the NetworkManager's StateChanged signal and emits a networkStateChanged signal, so we can react to a network state change even when PackageKit is stopped. In this case, we update all properties, which triggers PK to run and emits the appropiate PK signals as expected. --- src/CMakeLists.txt | 1 + src/daemon.h | 1 + src/daemonprivate.cpp | 14 ++++++++ src/daemonprivate.h | 3 ++ src/networkmanagermonitor.cpp | 66 +++++++++++++++++++++++++++++++++++ src/networkmanagermonitor.h | 55 +++++++++++++++++++++++++++++ 6 files changed, 140 insertions(+) create mode 100644 src/networkmanagermonitor.cpp create mode 100644 src/networkmanagermonitor.h diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index dac2104..2ed020d 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -22,6 +22,7 @@ set(packagekitqt_SRC transactionprivate.cpp details.cpp offline.cpp + networkmanagermonitor.cpp ) find_path(PK_INTERFACES_DIR org.freedesktop.PackageKit.xml diff --git a/src/daemon.h b/src/daemon.h index 449cf17..51a818f 100644 --- a/src/daemon.h +++ b/src/daemon.h @@ -869,6 +869,7 @@ private: Q_DECLARE_PRIVATE(Daemon) Q_PRIVATE_SLOT(d_func(), void propertiesChanged(QString,QVariantMap,QStringList)) Q_PRIVATE_SLOT(d_func(), void updateProperties(QVariantMap)) + Q_PRIVATE_SLOT(d_func(), void getAllPropertiesIfPackageKitNotRunning()) Daemon(QObject *parent = nullptr); static Daemon *m_global; }; diff --git a/src/daemonprivate.cpp b/src/daemonprivate.cpp index 829ba22..2c6bdfc 100644 --- a/src/daemonprivate.cpp +++ b/src/daemonprivate.cpp @@ -70,6 +70,20 @@ DaemonPrivate::DaemonPrivate(Daemon* parent) }); getAllProperties(); + + // If PackageKit is not running, we are not getting a signal when + // properties are updated (like when the network changes its state) + // so we connect to the NetworkManager dbus signal directly and then + // get all properties again to force packagekit to run and + // update the properties so we can emit the appropiate signals. + q_ptr->connect(&networkManagerMonitor, SIGNAL(networkStateChanged(uint)), + SLOT(getAllPropertiesIfPackageKitNotRunning())); +} + +void DaemonPrivate::getAllPropertiesIfPackageKitNotRunning() +{ + if (!running) + getAllProperties(); } void DaemonPrivate::getAllProperties() diff --git a/src/daemonprivate.h b/src/daemonprivate.h index 729e3ec..0fa645b 100644 --- a/src/daemonprivate.h +++ b/src/daemonprivate.h @@ -27,6 +27,7 @@ #include "daemon.h" #include "offline.h" +#include "networkmanagermonitor.h" Q_DECLARE_LOGGING_CATEGORY(PACKAGEKITQT_DAEMON) Q_DECLARE_LOGGING_CATEGORY(PACKAGEKITQT_OFFLINE) @@ -72,10 +73,12 @@ protected: uint versionMinor = 0; bool locked = false; bool running = false; + NetworkManagerMonitor networkManagerMonitor; protected Q_SLOTS: void propertiesChanged(const QString &interface, const QVariantMap &properties, const QStringList &invalidatedProperties); void updateProperties(const QVariantMap &properties); + void getAllPropertiesIfPackageKitNotRunning(); }; } // End namespace PackageKit diff --git a/src/networkmanagermonitor.cpp b/src/networkmanagermonitor.cpp new file mode 100644 index 0000000..05ddb87 --- /dev/null +++ b/src/networkmanagermonitor.cpp @@ -0,0 +1,66 @@ +/* + * This file is part of the QPackageKit project + * Copyright (C) 2019 Daniel Nicoletti <dantti12@gmail.com> + * Copyright (C) 2019 Antonio Larrosa <alarrosa@suse.com> + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Library General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
