4 years agoFix interaction of garbage collector with JS objects during QML type instantiation
Simon Hausmann [Wed, 14 May 2014 14:04:33 +0000 (16:04 +0200)]
Fix interaction of garbage collector with JS objects during QML type instantiation

It may happen that during the lengthy process of instantiating a tree of
objects for QML, the garbage collector runs.

For objects created by QML we support different ownership models, for example
in QtQuick visual parents keep their visual children alive, despite perhaps a
lack of QObject parentship. That ownership becomes active once the QML
autoparent function has assigned the correct visual parent, which happens after
object instantiation (after QQmlObjectCreator).

Similarly when a composite type is created, its QObject parent is only set
after all properties have been set. The root QObject is kept alive through a
special boolean, but if the sub-objects aren't children yet, their JS wrapper
might get deleted. For composite types with var properties, that also means
their var properties get deleted, such as the model property of TableView.qml
in the bug report.

In the future we want to support creating QWidget hierarchies with QML, which
also for layouts may rely on a delayed parent assignment for layouts.

To accommodate all this, this patch introduces an array on the JS stack that
keeps track of all JS wrappers for all QObjects created. This array is alive
during object tree creation. Afterwards, the different ownership models take
over, for example the auto parent function assigning a visual parent.

This patch also fixes an off-by-one in the total object count calculation
for composite types, where when instantiating a composite type as a sub-object
we counted the sub composite's object count but forgot the object itself.

safer to ensure that the window cannot be doubly deleted, in spite

Fix intermittent crash with older MinGW releases

An alternate code-path was previously added to work around a bad
signature for the SHParseDisplayName() function in older and non-w64
versions of the MinGW headers. This code-path incorrectly passed a
single rather double indirect pointer to the third argument of that
function causing it to produce corrupt data and subsequently crash.
This change modifies the code to instead cast a pointer of the correct
type to the incorrect type expected by the headers.

Fix crash when deleting component in Component.onComplete through loader

This is a regression introduced with Qt 5.3.0. The recursion watcher code that
is supposed to handle the test case of QTBUG-39775 can detect the recursion
into the object creator. However the boolean that indicates the recursion is a
member of a structure that's deleted afterwards. To avoid access to deleted
memory, this patch simply reference counts data structure shared between the
creators and also wraps the recursion watcher into a convenience class that
also increases/decreases the reference count accordingly.

QObjectPrivate::deleteChildren() itself sets entries

4 years agoUse QSignalSpy instead of waitFor in tst_qpacketprotocol
Ulf Hermann [Mon, 16 Jun 2014 09:21:01 +0000 (11:21 +0200)]
Use QSignalSpy instead of waitFor in tst_qpacketprotocol

QTcpServer::waitForNewConnection() blocks the event loop and prevents
the client, that runs in the same event loop, from sending anything.
Also, if the connection is established before waitForNewConnection() is
called we're going to wait for another connection, which will never

It's not clear if this is actually the cause of the test failures but
blocking the event loop is generally a bad idea and the last change to
the test that actually made a difference to the functionality added
exactly that line, see b36bbe3626bc68ac267d7653fa6408a8f258251d.
