Fix nasty bug in property cache leading to inaccessible signal parameters

The property cache among other things caches the parameter types and names
of signals (instead of retrieving them from the meta-object each time). When
this cache is created through createArgumentsObject(), the parameter names have
to be provided, but the signature didn't enforce that because of the parameter
names having a default value of an empty list. All call sites however provided
the correct list, except for one in QQmlPropertyCache::methodParameterTypes.

Consequently tst_qqmlecmascript::threadSignal() would fail occasionally because
the first time this cache was "created" was when the "done" signal was emitted,
which caused QQmlBoundSignalExpression::evaluate to call methodParameterTypes. If
the signal data had not been cached so far, a new cache with an empty parameter
name list was created.

Later (in the second half of the test) a new signal handler was compiled and
the property cache reported that the signal took no parameters.

10 years agoVisualization modes for rendering.
Gunnar Sletta [Sat, 7 Dec 2013 08:41:44 +0000 (09:41 +0100)]
Visualization modes for rendering.

There are two ways of setting this right now. One is to set it on
startup using an environment varible.

QSG_VISUALIZE=

"batches" - Visualize batchtes in the renderer. Merged batches are
drawn with solid color and Unmerged batches are drawn with a diagonal
line pattern. Few unique colors means good batching. Unmerged batches
are bad if they contain many individual nodes.

"clip" - Visualize clipping as red areas on top of the scene.

"overdraw" - Visualize all items in 3D to highlight overdraws. This mode
can also be used to detect geometry outside the viewport to some
extent. Opaque items are rendered with a green tint while translucent
items are rendered with a red tint. The bounding box for the viewport
is rendered in blue.  Opaque content is easier for the scenegraph to
process and it can also be faster to render on some hardware.

"changes" - Changes in the scenegraph are visualized with a flashing
overlay with a random color. Changes on a primitive is visualized with
a solid color while changes in an ancestor, such as a matrix or
opacity changes is visualized with a pattern.

The second way to set the visualization mode is to set it at runtime
through QString QQuickWindowPrivate::customRenderMode. This "API" is
string based so it is not tied to the batch renderer and in theory can
support other custom renderers.

The visualized elements do not respect clipping and rendering order
is arbitrary.
