Besides, QPluginLoader::unload() was still doing +unloading, which it won't anymore. + +Not unloading plugins is Qt's policy, as decided during the 5.0 +development process and reaffirmed now in 5.6. This is due to static +data in plugins leaking out and remaining in use past the unloading of +the plugin, causing crashes. + +This does not affect QLibrary and QLibrary::unload(). Those are meant +for non-Qt loadable modules, so unloading them may be safe. + +Task-number: QTBUG-49061 +Discussed-on: http://lists.qt-project.org/pipermail/development/2015-November/023681.html +Change-Id: I461e9fc7199748faa187ffff1416070f138df8db +(cherry picked from commit 494376f980e96339b6f1eff7c41336ca4d853065) +Discussed-again-on: http://lists.qt-project.org/pipermail/development/2016-October/027476.html +Reviewed-by: Lars Knoll <lars.knoll@qt.io> +--- + src/corelib/plugin/qfactoryloader.cpp | 6 ++++-- + src/corelib/plugin/qpluginloader.cpp | 5 +++-- + 2 files changed, 7 insertions(+), 4 deletions(-) + +diff --git a/src/corelib/plugin/qfactoryloader.cpp b/src/corelib/plugin/qfactoryloader.cpp +index dcf1b1a..b6558f5 100644 +--- a/src/corelib/plugin/qfactoryloader.cpp ++++ b/src/corelib/plugin/qfactoryloader.cpp +@@ -208,10 +208,12 @@ void QFactoryLoader::update() + ++keyUsageCount; + } + } +- if (keyUsageCount || keys.isEmpty()) ++ if (keyUsageCount || keys.isEmpty()) { ++ library->setLoadHints(QLibrary::PreventUnloadHint); // once loaded, don't unload + d->libraryList += library; +- else ++ } else { + library->release(); ++ } + } + } + #else +diff --git a/src/corelib/plugin/qpluginloader.cpp b/src/corelib/plugin/qpluginloader.cpp +index 37f2368..0ea8280 100644 +--- a/src/corelib/plugin/qpluginloader.cpp ++++ b/src/corelib/plugin/qpluginloader.cpp +@@ -148,6 +148,7 @@ QPluginLoader::QPluginLoader(const QString &fileName, QObject *parent) + : QObject(parent), d(0), did_load(false) + { + setFileName(fileName); ++ setLoadHints(QLibrary::PreventUnloadHint); + } + + /*! +@@ -342,7 +343,7 @@ static QString locatePlugin(const QString& fileName) + void QPluginLoader::setFileName(const QString &fileName) + { + #if defined(QT_SHARED) +- QLibrary::LoadHints lh; ++ QLibrary::LoadHints lh = QLibrary::PreventUnloadHint; + if (d) { + lh = d->loadHints(); + d->release(); +@@ -391,7 +392,7 @@ Q_GLOBAL_STATIC(StaticPluginList, staticPluginList) + \brief Give the load() function some hints on how it should behave. + + You can give hints on how the symbols in the plugin are +- resolved.
