We had reasoed that deadlocks would only occur if -the object creation in instance() recursed into its own instance(), -which was already a bug. But we had forgotten that dlopen()/ -LoadLibrary() executes initialization code from the module being loaded, -which could cause a recursion back into the same QPluginLoader or -QLibrary object. This recursion is benign because the module *is* loaded -and dlopen()/LoadLibrary() returns the same handle. - -[ChangeLog][QtCore][QLibrary and QPluginLoader] Fixed a deadlock that -would happen if the plugin or library being loaded has load-time -initialization code (C++ global variables) that recursed back into the -same QLibrary or QPluginLoader object. - -PS: QLibraryPrivate::loadPlugin() updates pluginState outside a mutex -lock, so pluginState should be made an atomic variable. Once that is -done, we'll only need locking the mutex to update errorString (no -locking before loading). - -Fixes: QTBUG-83207 -Task-number: QTBUG-39642 -Change-Id: Ibdc95e9af7bd456a94ecfffd160209304e5ab2eb -Reviewed-by: Volker Hilsheimer -Reviewed-by: David Faure ---- - -diff --git a/src/corelib/plugin/qlibrary.cpp b/src/corelib/plugin/qlibrary.cpp -index ddb053c..be9d92b 100644 ---- a/src/corelib/plugin/qlibrary.cpp -+++ b/src/corelib/plugin/qlibrary.cpp -@@ -576,9 +576,7 @@ - - Q_TRACE(QLibraryPrivate_load_entry, fileName); - -- mutex.lock(); - bool ret = load_sys(); -- mutex.unlock(); - if (qt_debug_component()) { - if (ret) { - qDebug() << "loaded library" << fileName; -diff --git a/src/corelib/plugin/qlibrary_unix.cpp b/src/corelib/plugin/qlibrary_unix.cpp -index 017aa97..a5c72f8 100644 ---- a/src/corelib/plugin/qlibrary_unix.cpp -+++ b/src/corelib/plugin/qlibrary_unix.cpp -@@ -123,6 +123,7 @@ - - bool QLibraryPrivate::load_sys() - { -+ QMutexLocker locker(&mutex); - QString attempt; - QFileSystemEntry fsEntry(fileName); - -@@ -213,6 +214,7 @@ - } - #endif - -+ locker.unlock(); - bool retry = true; - Handle hnd = nullptr; - for (int prefix = 0; retry && !hnd && prefix < prefixes.size(); prefix++) { -@@ -273,6 +275,8 @@ - } - } - #endif -+ -+ locker.relock(); - if (!hnd) { - errorString = QLibrary::tr("Cannot load library %1: %2").arg(fileName, qdlerror()); - } -diff --git a/src/corelib/plugin/qlibrary_win.cpp b/src/corelib/plugin/qlibrary_win.cpp -index 000bf76..ef58724 100644 ---- a/src/corelib/plugin/qlibrary_win.cpp -+++ b/src/corelib/plugin/qlibrary_win.cpp -@@ -78,6 +78,7 @@ - // fileName - // - // NB If it's a plugin we do not ever try the ".dll" extension -+ QMutexLocker locker(&mutex); - QStringList attempts; - - if (pluginState != IsAPlugin) -@@ -95,6 +96,7 @@ - attempts.prepend(QDir::rootPath() + fileName); - #endif - -+ locker.unlock(); - Handle hnd = nullptr; - for (const QString &attempt : qAsConst(attempts)) { - #ifndef Q_OS_WINRT -@@ -115,6 +117,7 @@ - #ifndef Q_OS_WINRT - SetErrorMode(oldmode); - #endif -+ locker.relock(); - if (!hnd) { - errorString = QLibrary::tr("Cannot load library %1: %2").arg( - QDir::toNativeSeparators(fileName), qt_error_string()); -- cgit v1.2.3
