This Week...

Akonadi server now supports searching via 3rd party search plugins which means it can retrieve results very quickly; it also supports server-search, so searching items not indexed by a local indexing service. Systemtray allows DBus-activation for Plasmoids. Dolphin and KMail's messagelist filter and search windows have been ported to Baloo. Okular adds tabbed interface. In KDevelop, it is now possible to jump to runtime output error messages. Kate adds keyword-based completion model. Google Drive API support has been added.

Bug Fixes

Development Tools

Milian Wolff committed changes in [kdevelop] debuggers/gdb/gdbvariable.cpp:

Fix inspecting of nested STL containers.

The problem is that GDB MI shows no children for dynamic STL objects,
it just add "dynamic" attribute to it. Here is -var-list-children
output for std::map< int, std::vector<std::string> > object:

SEND: "-var-list-children --thread 1 --frame 0 --all-values "var1" 0 5
kdevelop(20230)/kdevelop (gdb debugger) GDBDebugger::GDB::processLine:
GDB output:
exp="[0]",numchild="0",value="0",type="const int",thread-id="1"},
type="std::vector<std::basic_string<char, std::char_traits<char>,
std::allocator<char> >, std::allocator<std::basic_string<char,
std::char_traits<char>, std::allocator<char> >
> >",thread-id="1",displayhint="array",dynamic="1"}],has_more="0""

As you see, the second variable, std::vector<std::string> has
numchild="0", but dynamic="1". This patch adds extra check for
"dynamic" attribute in variables.

- change the font of the help panel to monospace
- escape spaces in the help messages, as they might be important for formatting

Patch by Yichao Zhou, thanks!

Andreas Cord-Landwehr committed changes in [parley] /:

Removes gradient in grade statistics.

This closes the mentioned bugs, as it removes the gradient in learning statistics and uses solid color.
It also makes it even more intuitive for the user, as it uses a single color for all the grades with different alpha values, increasing as grades increase. Thus darker shades mean higher grades.
Also, the grade color settings in Parley configuration have been changed, removing the different color palletes for all grades and leaving just a single base color for all the grades.
The "Use colors" option has been removed from the configuration.
Also, the font color for the translations in the editor has been changed to be the default black, making the text more readable.

Quick Open in tab bar: Show number of hidden documents

With this patch, the quick open button in the view space tab bar shows
the number of hidden documents by showing e.g. "+5" as button text. This
way, the users should always be aware that there are more documents open
that currently do not fit into the tab bar due to lack of space.

Further, this patch adds a What's This tip to the quick open button that
explains in detail what this is all about.

Kurt Hindenburg committed changes in [konsole] /:

Restore --background-mode

For now restore this option that was removed for 2.11. This option
is somewhat a hack and abnormal feature. However, it seems a number
of people use it and I can see how it would be useful. So instead of
spending a lot of time right now trying to correct the issues, just
restore the previous code.
Ideally for KDE 5, this portion of the code can be better handled.

Vishesh Handa committed changes in [baloo] src/file/fileindexerconfig.cpp:

FileIndexerConfig: Disable initial update for files

When baloo_file starts it looks through every file in your filesystem
which should be indexed and compares the mtime of each of them with the
mtime stored in the db.

This is useful to detct changes which occured when baloo_file was not
running. However, baloo should always be running so we don't really need
to check this on startup. It causes large amount of disk io on startup.

Fix a crash when trying to D&D too big layer (>20MiB)

Qt implements D&D using X11 window properties, which were probably
not supposed to be used for transferring 20+MiB between applications.
So we indroduced a new "application/x-krita-node-url" mime format
which saved the image into a temporary directory and passes the url only.
That is the way Qt handles "application/x-qt-image" itself.

Dmitry Kazakov committed changes in [calligra] krita/ui/

Fixed the half of the Pen/Eraser flip bug

We should call the update slot explicitly when changing the paintop preset
and do not rely on the widgets, which would also emit the update signal, but
later. We can't wait for widgets because they use a deferring timer

Now it is left to fix the Windows-only problem.

The weirdest patch ever

There is a bug in Qt/X11 which prevents the QPainter::drawText() call
be used in any non-gui thread, even when
QFontDatabase::supportsThreadedFontRendering() returns true. It seems
like some function in the font rendering routine eats the X11 replies
which are awaited by the GUI thread, effectively making the GUI thread
to hang up. The hangup happens in xcb_wait_for_reply().

This dirty workaround makes the text brush be initialized in the
GUI thread, saved to a global singleton and then fetched by the
threaded code in the paintop. Yes, that is weird, but this is the
best thing we can do right now :(

Don't eat WinTab Proximity packets from the WinTab's queue!

Qt also needs these packets to issue the Enter/Leave events. So
just use the *Peek variant of the function instead of *Get.

User Interface

Sebastian Kügler committed changes in [plasma-framework] /declarativeimports/core:

Units reads longDuration from config file.

This reads the global animation duration value from plasmarc, and gets
notified of changes: change the file, all animations are updated

Put this into your plasmarc to disable animations globally:


As you might guess, other values will work as well.

shortDuration will always be 1/5 of this. (For now.)

1) don't rely on window()->screen() it's rubbish.

2) if the dialog is parented to a desktop, we want to position
inside the parent, not outside the parent object

Wolfgang Rohdewald committed changes in [kajongg/KDE/4.12] src/

make Random shuffle work with both Python 2.7.5 and 2.7.6

2.7.6 changed the API for shuffle(), released in November 2013.

This fix may change the minimal python version needed (currently 2.6.0).
But since I do not have anything older than 2.7.5 installed, it is
difficult to tell. I checked the history of python lib
and there _should_ be no problem.

People installing KDE/4.12 should already have some recent python,
so it should not matter. Anyway this is why I will not backport
this fix to KDE/4.11. And since 4.12.2 is about being released, I put
this fix into 4.12.3

Milian Wolff committed changes in [kdevplatform] /subversion:

SVN plugin: Never launch configured external diff and diff3 tools.

I have my command-line Subversion client set up to use colordiff
instead of the internal diff implementation, so of course instead of
seeing a nice diff in KDevelop, I got a mess of ANSI colour escape

This patch disables any external diff or diff3 tools configured in
the ~/.subversion/config file. It does this by modifying
configuration in memory right after it is parsed from disk (or
possibly the registry on Windows). This way, we can safely assume
that running a diff or merge will produce unidiff format, and the
config file doesn't have to be changed.

N.B., it may be necessary to override the merge-tool command

Sebastian Kügler committed changes in [kde-workspace] /generic/applets/systemtray/plugin/protocols/plasmoid:

[Systemtray] DBus-activation for Plasmoids

This feature allows loading and unloading Plasmoids when dbus services
come and go. Applets can specify in their metadata which service should
control their lifecycle.

This has the following advantages:
- We can dynamically only load Plasmoids when they're useful
- Applications can provide Plasmoids that appear and disappear bases on
the application running
- We can load controls for system service dynamically as they come and
- It makes it easier to delay loading of Plasmoids on startup until when
a specific service appears
- It makes Plasmoids and features more discoverable

One immediate user for this is the media controller applet, which will
now only be loaded once an MPRIS2-compatible media player is running.

Internally, this works as follows:
- we collect a list of plugins and related services in
- we query DBus for the list of services, async (initDBusActivatables())
- we go over that list, adding tasks when a service and plugin match
- we start watching for new services, and do the same
- whenever a service is gone, we check whether to unload a Plasmoid

Adding the following to the metadata.desktop file will trigger loading
the applet whenever a service matching the service name appears. The
applet will automatically be unloaded once the service disappears.


This feature was discussed and requested during the Plasma Sprint in

Martin Gräßlin committed changes in [kwindowsystem] /:

Introduce runtime platform support in KWindowSystem

This is a change similar to the one in KWindowInfo, but with variation
to the pattern due to the static container.

There is now a generic implementation of KWindowSystem which is
completely windowing system platform independent. This implementation
delegates all methods into a KWindowSystemPrivate class.

Each windowing system platform implementation needs to provide a
subclass (e.g. KWindowSystemPrivateX11) and provide all the methods
which are delegated. To make use of a platform implementation it needs
to be included in the ctor of KWindowSystemStaticContainer.

There is a dummy implementation for all not supported windowing system

This change also includes some API changes:
* KWindowSystem::windows() returns a copy instead of const-ref
* All methods are provided, there is no longer X11 specific methods
* private methods and enums are removed

NOTE: This change breaks the implementation for Windows and Mac OS!
They are currently excluded from build.

Merge branch 'server-search'

Akonadi server now supports searching via 3rd party search plugins (for
example Baloo plugin), which means we can retrieve results very quickly,
while not having to depend on 3rd party code, like we did with Nepomuk.

More importantly, we now support so called server search (or agent search).
Search results are not retrieved only from the search plugins, be the server
will also query agents and resources that implement AgentSearchInterface
to retrieve search results from their storage search service (for example
IMAP SEARCH extension). This makes it possible to retrieve search results even
for items that don't have full payload cached in Akonadi and therefore cannot
be indexed by Baloo or Nepomuk.

Big thanks to Christian Mollekopf for his help with implementing this.

Implement support for server-side search in Akonadi

Instead of using Nepomuk and SPARQL queries, we now use SearchQuery and SearchTerm objects

query language.

We now also support server-search, so agents that implement AgentSearchInterface can search
their storage service (like IMAP SEARCH for example) and return results back to Akonadi. This
allows us to search even items that are not indexed by a local indexing service, like Nepomuk
or Baloo.

The zoom range (0 to 200) is adjusted to fit each puzzle as it loads,
with close-up view near one end and full-puzzle view near the other and
smoother operation in between. The close-up view is always larger than
the full view and can never be closer than a noticeable margin, even in
puzzles with a small number of pieces.

The scene is populated with items and sized only when all pieces have
been loaded from files, constructed, positioned and joined together (if
previously solved). A frame is added and the whole scene is fitted into
the view closely, showing the whole puzzle. Loading times are improved.

Cristian Oneț committed changes in [kmymoney] /widgets:

Performance optimization of the register view.

Instead of setting one delegate (the same) for each row by using
QAbstractItemView::setItemDelegateForRow() set the delegate for the
whole view using QAbstractItemView::setItemDelegate(). This way the
view will perform better because the delegate it uses does not depend
on the row on which it needs to be used.

QAbstractItemView::setItemDelegateForRow/Column should only be used if
a different delegate is needed for different rows/columns.

Wouldn't have spotted this without the help of callgrind. I must have
used setItemDelegateForRow() in the early days of my MV programming.

Cristian Oneț committed changes in [kmymoney] /mymoney:

Performance optimization for MyMoneySeqAccessMgr::price().

Added testcases for this method.

According to valgrind this was the most expensive method of the
MyMoneySeqAccessMgr class which, in turn, was the most expensive
KMyMoney class considering the execution time.

After this price() moves bellow the transactionList() and
calculateBalance() methods and MyMoneySeqAccessMgr moves bellow
clases like MyMoneySplit and MyMoneyTransactionFilter.

Anton Kreuzkamp committed changes in [qmlweb] /:

Refacture object creation & property type handling

This commit brings a refactoring of how
- the meta code from the parser looks like (it's now using javascript
constructors more extensively)
- QML elements are constructed (mostly moving code around)
- property values are assigned to the properties. Now each property has a
proper type and the new value will be passed to a constructor to match the
type. This considers basic types like integer, strings, colors and lists as
well as object types like Item, Rectangle or Component (assigning a Rectangle
to an Item-property is handled correctly (create a rectangle) as well as
assigning it to a component (create a component)).

Moreover property values are now assigned to the properties during the object
construction. Bindings are assigned but not evaluated. The evaluation happens in
a second run after all objects are created (prior all property values were
assigned here). This fixes context problems with object type properties (like
states) in conjunction with components (see last commit) and fixes the issue
that those objects were created multiple times.
