---------------
ubuntu-ui-toolkit (1.3.1872+16.04.20160308-0ubuntu1) xenial; urgency=medium
[ Timo Jyrinki ]
* Fix gles unit test skipping.
* Add s390x to the unit test skipping architectures
* UITK test plan - wily -> xenial. Fixes LP: #1544490
[ Christian Dywan ]
* Print errors when QuickUtils fails to create a component.
* unit tests shouldn't use deprecated Dialog.callera
* Correctly count only test case results. The result= value is used in suites
and results.
* Skip tst_pagehead_visible flakes on non-arm. Fixes LP: #1534651
* Skip flaky tst_mousefilterTest::doubleClicked. Fixes LP: #1542215
* Suppress click signal if releasing outside of ListItem. Fixes LP: #1541148.
* Use gdb in runtest.sh to produce backtraces.
* Arrow keys change value of a Slider. Fixes LP: #1523824.
* Only use Maliit when enabled explicitly in the environment
[ Oliver Tilloy ]
* Do not try to assign to non-existent property "activeFocusOnPress".
Fixes LP: #1532953
* Bubble up ESC key press event if there is no popover to close.
Fixes LP: #1546627
[ Loïc Molinari ]
* Added private items and nodes for the new component styles.
Fixes LP: #1523836
* Made use of new private Frame item for the focusing.
* Fixed performance monitor crash because of a NULL timer pointer dereference.
Fixes LP: #1546986

values.
Fixes LP: #1546546

[ Florian Boucault ]
* Always on performance monitor that logs frames that too long to render.
* MainView: proceed to selecting the theme automatically at startup too.
Fixes LP: #1535819
* MainView: when no gradient color is needed for the background, rely on
QQuickWindow's GL clear color. Lessens overdraw considerably for most
apps. Fixes LP: #1439133.
* Panel: MathUtils used without import prefix was leading to undefined
reference.
* Label: use native rendering on low dpi screens (GRID_UNIT_PX <= 10) for
sharper looking text.

[ Tim Peeters ]
* Support scrolling in ListViews with horizontal orientation to the
qquicklistview CPO.

* Fix the autopilot failures introduced with the horizontal scrolling in
the Flickable CPO.
* Update documentation for MainView, Page, AdaptivePageLayout to use the new
PageHeader in all examples. Deprecate old properties. Fixes LP: #1540574
* Add 'animate' property to new internal AppHeaderBase, and do not show a
header animation when starting an app without header.
Fixes LP: #1518002, LP: #1524901.

[ Andrea Bernabei ]
* Refer to SlotsLayout.Last instead of SlotsLayout.End in SlotsLayout
documentation. Fixes LP: #1536170.
* Update "Import Statement:" in docs of Ubuntu.Components. Currently
Developer's website shows "import Ubuntu.Components 1.2" and "since
Ubuntu.Components 1.3" and that is confusing for all app developers.
Fixes LP: #1531817.
* Fix ListItemLayout multiline labels positioning and add docs about

components. First set of visual updates including ListItem, Text inputs,
CheckBox, Switch, Slider, PageHeader, ActionBar and BottomEdge.
Fixes LP: #1350915.
* Contextual Actions - shortcut (and mnemonics) handling must obey
active/inactive contexts, such as Page activation as well as Popups and
Dialogs. Fixes LP: #1514856.
* Attach default theme to the QML Engine it creates. Fixes LP: #1527546
* Palette fix. Update components to use the palette. Fixes LP: #1495477
* Disable rendering performance logs for the unit tests.
* Specify message severity for the performance logging category.
* Link singletons used as context properties in root context of the QML
Engine to the engine instance. Fixes LP: #1539558.
* Specify message severity for the performance logging category.
* Expose Icon.asynchronous property to drive image loading of the icon.
Fixes LP: #1535480.
* Redo InverseMosueArea tests to not to use shared view for all the tests.
Fixes LP: #1544455

creation. Adjust failing test cases. Fixes LP: #1542309

Fixes LP: #1549830
* Introduce AdaptivePageLayout.asynchronous to the API. Fixes LP: #1540449

to extend sensing area even further. Fixes LP:#1468645, LP: #1508114
[ Albert Astals Cid ]
* Have a default pixelsPerInch value. Otherwise when running unity8 tests
under xvfb we get the wrong parameters warning and tests fail.
[ Robert Ancell ]
* Fix documentation typo - Ubunut -> Ubuntu.
* Use new QML package name for qml-module-qtfeedback, drop old QML
package names.
* Fix examples using OptionSelectorDelegate that place it in the Toolkit
namespace but don't have the import to match.
[ Colin Watson ]
* Make src/Ubuntu/Test depend on src/Ubuntu/Components, to fix build with
high parallelisation.
[ Pierre Bertet on 2016-02-17
* ComboButton: not based on Button anymore + style update.
[ CI Train Bot ]
* No-change rebuild.

Title:
UbuntuTestCase's flick() function is unreliable, does not always flick
a Flickable
Status in ubuntu-ui-toolkit package in Ubuntu:
Fix Released
Bug description:
revision 1864
System setup: Vivid + Overlay PPA (i.e. same as phones/tablets)
libqt5qml5:
Installed: 5.4.1-1ubuntu11~overlay3
libqt5core5a:
Installed: 5.4.1+dfsg-2ubuntu11~vivid4
UbuntuTestCase provides a flick() function whose main purpose is to
produce a flick event when executed on Flickable.
I noticed that this does not always happen, causing flakiness of some
of the UITK tests (in my case, it's the Scrollbar/ScrollView tests I'm
working on)
Here is a test case that reproduces the issue, once every 10-200 runs,
depending on the configuration (I use a simple script to run it until
it fails)
Please note that uncommenting the debug lines such as onMovingChanged
onFlickingChanged will make it harder to reproduce the bug.
Enabling QT_LOGGING_RULES="qt.quick.mouse.debug=true" or
onContentYChanged will make it even harder.
Since I already went through the effort, I'm posting here the debug log
coming from the failed and successful runs:
- Typical failed run ---> http://pastebin.ubuntu.com/15186789/ Note how
"flicking" never becomes true
- Typical successful run ---> http://pastebin.ubuntu.com/15186784/
- Failed test with qt.quick.mouse.debug=true -->
http://pastebin.ubuntu.com/15186851/
- Successful test with qt.quick.mouse.debug=true ->
http://pastebin.ubuntu.com/15186853/
Here's the code I used to reproduce the bug:
import QtQuick 2.4
import QtTest 1.0
import Ubuntu.Test 1.0
import Ubuntu.Components 1.3
import Ubuntu.Components.Styles 1.3
import QtQml.Models 2.1
Item {
id: main
width: units.gu(50)
height: units.gu(100)
SignalSpy {

SignalSpy {

}
Item {
anchors.fill: parent
Item {
width: units.gu(20)
height: units.gu(30)
property alias flickable: freshFlickable
Flickable {
id: freshFlickable
anchors.fill: parent
contentHeight: content.height
contentWidth: content.width
clip: true
//onContentYChanged: console.log(contentY)
//onMovingChanged: console.log("MOVING", moving)
//onFlickingChanged: console.log("FLICKING", flicking)
Rectangle {
id: content
width: units.gu(40)
height: units.gu(200)
color: "blue"
}
}
}
}
UbuntuTestCase {
name: "FlickBug"
when: windowShown
function setupSignalSpy(spy, target, signalName) {
spy.clear()
//reset signalName otherwise it will look for the old signalName
in the new target
spy.signalName = ""
spy.target = target
spy.signalName = signalName
}
function test_flickUbuntuTestCase() {
setupSignalSpy(signalSpy, freshFlickable, "movingChanged")
flick(freshFlickable, 50, 50, -units.gu(10), -units.gu(10))
signalSpy.wait()
compare(signalSpy.count, 1, "No movingChanged signal after
simulating a flick.")
}
}
}
