This Week...

Calligra Stage gets a new user interface for creating and editing custom slide shows in it's Slides Sorter View. Gapless playback is implemented in Phonon-GStreamer. For rekonq adding favorites is made easier and a user interface option for configuring the do not track header is added, there are also updates to the SSL support. The Public Transport applet can now show stops in Marble with the updated OpenStreetMap data engine. In kdelibs we have an usability improvement in the Edit File Type button and an introduction of package cache for Plasma. Kate now correctly handles comments when doing static code wrap. Bugfixes were made to a very diverse range of applications, including KDevelop, Marble, and Network Management.
Ivan Čukić explains the use of the new activity manager which has seen much commit activity in the previous week.

The Activity manager is a service that handles user's activities and tracks the resources (documents, e-mails, contacts, web pages etc.) that the user opens.


The "activity" is an abstract concept which is intended to help the user organize her work. For example, activities can range from general "Web browsing" or "Gaming" to more specific like "Learning Physics 101", "Writing a paper on multi-dimensional fuzzy sets" or "Doing KDE Plasma development".

In Plasma and KWin, activities are exposed as different sets of desktop widgets and windows to allow users to create a per-task experiences with different desktop icons, widgets and applications that are specific to the task at hand etc.

One step more

While this separation was quite useful, it was only the first step. Namely, apart from having only different sets of tools for different tasks, it would be rather nice to have different 'favourite applications' in the application launcher (no point to show KDevelop in an artwork related activity), different recent documents list (why would you need a film you watched the day before while developing software), to show only important contacts for the activity you're in and similar.

The activity manager allows the program developers to be able to react to the changes in the current activity to be able to provide only relevant data.

User activity tracking

The new thing in the current version of the Activity manager, that was a long time in the making, and now is being developed as a part of the KDE Contour project, was the ability of the service to record the user's actions to be able to provide automatic scores to the accessed resources.

One of the things I never liked about the 'recent documents' system is the fact that it usually contains more items that the user will never need again than those that are important. Amarok has a nice way of scoring the songs based on how many times a certain song was listened to, whether it was explicitly chosen to play, whether the playback was interrupted by the user and similar.

We aim to do the same for most resources the user can access, but with some important changes. Currently, the score is calculated using the number of times the resource was opened, for how long it was kept open, and when was the last time the user accessed it.

In the future, the system will be improved by also tracking for how long a certain resource has had the focus. So, if you keep something open, but minimized, it will not get a high score.

This will make the 'recent documents' feature quite irrelevant and replace it with the 'important documents'.


While the main purpose was to have the system be able to understand what is important to the user, there are a few quite nice possibilities that arose from the fact we can now know what documents are open at a specific time.

The first is the global Share-Like-Connect system which will (apart from other things) allow the user to share the currently open document with friends, without the need to open a web browser, or an e-mail/IM client. Just select where you want it posted, or to whom, and all will be done automagically.

The second side-effect will be the ability to develop a truly document-based desktop and mobile environment compared to the today's application-centric systems.

Bug Fixes

Development Tools

David Nolden committed changes in [kdevplatform] /:

Don't clear the area while switching the working-set as result of viewAdded().

This fixes possible crashes and makes the document-controller test work again.

Olivier Jean de Gaalon committed changes in [kdevelop] /cpp/cppduchain:

Guillaume Martres committed changes in [marble/kde-4.7] src/lib/PlacemarkLayout.cpp:

PlacemarkLayout: avoid having deleted VisiblePlacemarks in m_paintOrder

setCacheData() runs qDeleteAll on m_visiblePlacemarks but did not remove
them from m_paintOrder. This could cause random crashes (semi-reproducible
at startup by moving/clicking the mouse before the map is loaded).
(cherry picked from commit 78980c378a7eff47fd68ad4b013f0d5c346315ef)

Bernhard Beschow committed changes in [marble] src/lib/StackedTileLoader.cpp:

Alex Fiestas committed changes in [kde-workspace] kcontrol/randr/randrscreen.cpp:

Don't react if output changes, KRandRTray is not the only boy in town

If you change a config with the KCM and the KRandRTray is executed, when
you change your configuration KRandRTray will react on it and if you
have unityOutput activated, then KRandRTray will force that configuration
invalidating what you (user) did in the KCM.

This is yet another fix in the realm of "Don't do anything unless the
user ask for it".

Alex Fiestas committed changes in [bluedevil] /:

Show always the knownDevices while running a discovery at the background

This fixes one of the most hated behaviors of kio_bluetooth, before this
commit we were scanning always for new devices so in order to use your
device via kio_bluetooth it had to be in discoverable mode (and of
of course you had to wait a bit).
Now, we're showing always the knownDevices first, and start a
discovery each 20s. If a folder is acceed the discovery is stopped.


Kurt Hindenburg committed changes in [konsole] /:

Correct non-zero status notification such that it works.

The non-zero notification was being displayed for zero exit codes.

Thanks again to Jekyll Wu () for patch and research.


Aaron J. Seigo committed changes in [kdelibs] plasma/containment.cpp:

The 2 were inverted previously.

Alex Fiestas committed changes in [kde-workspace] kcontrol/randr/randrscreen.cpp:

Use the first (highest) resolution in common instead of last used

The last used resolution can be wrong, can be incompatible or can be
just "ugly" if you hardware setup has changed. This is the common
use case for KRandRTray when you use it to setup quickly and easy a new
To fix this wrong behavior (which may end in an unusable system) instead
of loading the last used resolution we're not loading the highest
resolution in common.

As a practical case, my laptop has 1280x800 and my LCD is 1920x1080, for
an unknow reason my las used resolution was 1024x768 which is not
working at all in either of the screens.

Finally I just want to note that this is the behavior that any RandR
user expect, unify outputs at the highest (better) resolution.

Andrea Iacovitti committed changes in [kdelibs/KDE/4.6] /rendering:

Fix infinite loop that can happen in some cases where colspan=0 or rowspan=0
because accessing empty structures. Tracking for not empty qmap by using
additional flag is redundant and buggy in this case.

Aaron J. Seigo committed changes in [kde-workspace/KDE/4.7] libs/plasmaclock/calendar.cpp:

don't bother limiting the number of events shown.

the data is already there in memory, it's at most one month of data and starts from the date the user selected, and apparently users expect to see it all .. which makes sense.
while i was in there, made some minor improvements to the code (style, efficiency..)

Fix regression introduced with 909b4efa

I still don't understand how I actually tested my patch
before committing. It was working, sigh. That were
several hours of annoyance including a git bisect presenting
my own commit I assumed to be correct. Sigh.

Andre Heinecke committed changes in [kdepim] ksendemail/main.cpp:

Add argument for the mail address again.

This argument had been removed in 3ce2855ab7abe1e7638c1d80dfb9cbf1ffcd6d59
Since then it has not been possible to use ksendemail to open
the messagecomposer with a prefilled "To: " field apart
from suppling the full Header.

This enables ksendemail again to function as the "default mail
application" on Windows correctly and open a Messagecomposer window
with a prefilled To: field (e.g. when opening mailto urls)

Lukáš Tvrdý committed changes in [calligra] filters/libmso/shapes2.cpp:

Fix oval callout shape equation

OpenOffice equation was wrong. 'W' command specification
consists of "line is then drawn from the current point to
the start angle of the arc" but OOo does moveTo instead
and that is specification of 'V' command.


Harald Sitter committed changes in [phonon-gstreamer] /:

Fix ADO returning 0 samples forever.

Since 2 channel input buffers were thought to be chopped by
QVector::resize() the emitted data never went beyond returning 0 if the
initial samples were 0. This is because resize() actually removes
elements at the end of the vector, however since the vector is actually
used like a queue we need to chop at the front. This is now simulated
by using remove(0, n) with n = dataSize*channels.
Also fix mono processing, instead of manually memcopying and whatnot we
now create an implicitly shared copy vector and resize it to the size
we need to return. This either results in implicitly shared remaining
memory or, which is more likely, only copies the elements that are to
be emitted. Eitherway a massive gain in readability.

Martin Gräßlin committed changes in [kde-workspace] kwin/CMakeLists.txt:

Build an additional kwin_gles binary

KWin gets compiled twice if OpenGL ES is available
and a second binary is created. It is linked against
the GLES effects and kwinglesutils and does not link
against OpenGL. The normal OpenGL variant is still
the "kwin" binary.

This is an intermediate step till we have the scene
as a loadable plugin. Then we will determine whether
OpenGL ES is supported in an external application
and load it as a plugin, otherwise we load the
OpenGL/GLX scene as a plugin.

Boudewijn Rempt committed changes in [calligra] krita/

Show a splashscreen while loading Krita.

The splash image is included from an xpm file since we cannot
use the application data directories before having setup all
the standard directories, so we cannot dynamically load a file.

Note that gimp and krita create xpm's that give lots of compile
warnings, so after changing the splash image, we need to add
a bunch of consts:


static char * splash_screen_xpm[]={

Harald Sitter committed changes in [phonon/qml] /:

initial ARB FP drawing

- only does RGB32 (just like msink in pgst)
- only can do aspect retaining scaling (just like before)
- ludicrous design (literally not existant actually), final design will
probably assume a mixture of qtquick2 like surfaces and various painter
implementations (we need at least raster and GSLS, and since it is now
around anyway ARB - perhaps something X too?)

by default we render using raster, if gl is available and PHONON_PAINT
is set to either gl (which paints using qimage texture upload thru
qlcontext) or directgl (which uses the ARB shader program)

for testing you could for example run:
export PHONON_PAINT=directl

Akarsh Simha committed changes in [kstars] /skyobjects:

Short circuit a whole lot of proper motion, precession, nutation,
aberration calculations if the time change is insignificantly small
compared to the time-scales of these effects.

Potentially dangerous. I've already found one bug in my code which I'm
going to fix right away.

The two primary factors leading to slow drawing are the drawing itself
and the JIT Update on DeepStarComponent. While using OpenGL rendering,
the former bottleneck is not as dominant as the latter one. This is
expected to make significant differences to FPS in OpenGL mode. In
QPainter mode, there were noticable differences seen using a profiler,
but very little visible difference (although there was visual evidence
of some improvement).

Akarsh Simha committed changes in [kstars] /skyobjects:

+ Separate the test for significant gravitational lensing around the
sun from the actual lensing calculation. Now there are two methods
-- checkBendLight() and bendlight(), the former doing the job of
checking whether the skypoint is close enough to the sun to be
lensed by its gravity.

+ [Major] Recompute coordinates of a SkyPoint only when about a minute
has passed since the last recomputation. This means that precession,
nutation, aberration, are calculated only when there are
sufficiently large changes in time. This is expected to increase the
speed of recomputing the skymap, although I have not tested the

This is also a potentially dangerous change. I've not tested to
check that precession is recomputed when the step is sufficiently

Big changes here in CameraGUI:

-Load camera icon view thumbnail on the fly. Do not load all of then at the first time, which time consuming.

-Reduce memory allocation of thumbs to only visible items.

-Reduce time loading at camera connection to only parse file system information not metadata from files, which time consuming.
Definitivly, camera connection duration is reduced by 10~20.

-Camera icon view are sorted by date from file system. Metadata are loaded on the fly, at the same time than thumbnails,
especially to display photo properties from tool-tips and right sidebar.
Note : at this commit, only USM camera is patched, GPhoto driver still todo.

-In camera drivers, simplify api and add new virtual methods to get full metadata container (not only exif). Always get metadata
through separate thread to reduce time latency in gui.

-In camera sidebar implementation, remove all dependencies to CameraIconView and CameraIconItem for future Qt4 model/view port
of camera icon view.

-Bug fix in UMSCamera driver about to load date time-stamp from file system : information is never stored through imagescanner.

-General implementation polish and optimizations, especially in camera item info container.

Aaron J. Seigo committed changes in [kdelibs/libplasma2] /:

give package a cache for found items; make the dptr implicitly shared

this drops a 100k loop of copies from ~2700ms to ~37ms and a 100k loop
of copy-n-find from ~3900ms to ~40ms.

the cache addition is predicated on the idea that lookups of the same files will be frequent enough to warrant the small amount of extra memory usage for the cache. if that does not hold in practice (though it appears to) then this will not be a gain and in fact be a small net loss for memory footprint

the dptr change is predicated on the assumption that copies of Package will be frequent, and so must be low cost. this is known to be true. even if it wasn't, there is no down-side to this change. the upside are significant time and memory savings.

Thomas Zander committed changes in [koffice] libs/flake/KToolManager.cpp:

Disabling the feature of locked layers.

Essentially this feature makes sure that it disables all tools from doing anything
on a layer that is either not editable or not visible.
While this is a great feature, it makes parts of koffice unuasable due to the fact that all apps
support layers (due to it being part of Flake and ODF) but not all apps can handle them.
So you can end up in a situation where showcase or kword has shapes that are uneditable and
there is no GUI to show why and no GUI to fix the situation.
So disabling this feature until we solve this usability bug.
