Issue 120

Fixing the bug that was causing runaway CPU usage when drawn lines moved off-screen at high zoom. Akarsh submitted a patch which fixed the symptom, but had some side effects. This patch reverts his change and corrects a very simple bug that was causing the problem.

We have a function SkyMap::onScreenLine( QPointF &p1, QPointF &p2 ) that returns the o-screen segment of a line, given endpoints p1 and p2. The modified on-screen endpoints are returned through the same reference values. In the case that no segment of the line connecting p1 and p2 passes through the SkyMap widget, null values of -10000000 are returned.

At some point, IIRC, James created an alternative onscreenLine2() function which does essentially the same thing, except it returns a bool instead of void, and the return value is used to indicate whether an onscreen line segment was found or not. There are no null values in this version of the function.

However, in one of the places where onscreenLine2() should have returned false (indicating the line was totally off-screen with no onscreen segment), it actually returned true. This was the cause of the runaway CPU usage.

James, can you confirm this patch, and then I will backport it to the 4.1 branch.

I don't remember why James created a second version of this function rather than modifying onscreenLine().

- Addressing the symptoms of the rendering desync.
This fixes the apparent visual desync problems.

However the way it gets done isn't satisfying and still has some less apparent bugs remaining, so I'll fix the issue entirely in a different way in my next commit.

Fix bug #126442
- ksnapshot can now capture the current screen in multi-head setups.

fix crash cause of a rather interesting design-decision in KConfig;

configgroup = KDesktopFile().desktopGroup() means that configgroup has now a dangling pointer to it's master :-/

Don't create the view* and save* actions when not in "browser" mode.
Only khtml_browser.rc lists those actions anyway, and this fixes Ctrl+U triggering "show html source" in kmail unwantedly.

Changes include
- the undo cursor and undo selection are saved with the first KateDocument::editStart()
- the redo cursor and redo selection are saved with the last KateDocument::editEnd()

For this to work, the following parts needed to be fixed
- wrap doDeleteWordLeft/Right with editStart() and editEnd(), otherwise wordLeft() and wordRight() change the cursor position
- drag & drop: while moving the cursor position is changed. To make it work, we need to fix the cursor position before we really do the drop operation. The undo selection is only set in the case of a move, otherwise it does not make sense (it feels really strange)

Please test the patch, as it should go into KDE 4.1 if it works. Right now, the KDE 4.1 branch crashes sometimes when doing undo/redo.

Port to KDE 4.1.0? Wait for KDE 4.1.1? dunno...

Also quit the event loop when a part still holds a reference to a KGlobal object, probably by a KJob which wasn't properly deleted.

This fixes that the Kontact process was still running (without a window) after viewing an article in Akregator.

The real fix would be to fix Akregator, it should take care of properly cleaning up each KJob.

@David: maybe KJob::allowQuitWhileJobsAreRunning(bool) wasn't such a bad idea after all?

Fixes merging/setting up of character formats.

KoCharacterStyle::applyStyle(block)
- Sets up the blockCharFormat and the charFormat KoCharacterStyle::applyStyle(cursor)
- Merges with the existing charFormat

I am writing a document on how ODF+styles work at <a href="http://wiki.koffice.org/index.php?title=KWord/Tutorials/OdfStyles">http://wiki.koffice.org/index.php?title=KWord/Tutorials/OdfStyles</a>; (nothing yet)

Be more careful in the event of a encrypted APIC frame (or compressed with no zlib in TagLib).

Code was put in to check for this earlier but was incomplete as although the pointer was correct it was still blindly dereferenced.

In addition add QImage header to coverinfo.h (was included indirectly before).

Neither of these need backported based on the rarity of encrypted/uncompressed picture frames but I'll probably backport the potential crash fix just in case.

Fixed crash when off is pushed while repopulating.
Fixed bad things happening when repopulate is pushed a bunch of times.
More reasonable results for infeasible sytems (i.e. you can put two artists at 100% and get about 50% of both).

* Add a QtScript module for scripting C# apps

Added support to be able to add a tool and an example for it.
More work on bzr example

Log and Status for git
The same changes in DVCSplugin (but no changes in Bazaar or Mercurial)

Store and load all the repositories from/to disk.
A unique directory for each kdevelop instance is used, so we don't get crashes from that.

What we store to disk now:
- Identifiers
- Macros
- 99% of environment management information(macro sets, string sets, etc.)
- Qualified identifiers
- Strings
- The complete type-system
- Comments
- C++ template instantiation information

The only missing part is the actual declarations/contexts, and the top-level environment management information.

Make the whole repository storing actually work, and add a lot of optional debugging code to itemrepository.h.

Pick the storage-directory from within itemrepository.cpp instead of duchain.cpp.

It is important that the repositories need to be loaded at the earlierst point possible. The problem: At that early point, neither KStandardDirs, nor KLockFile are functioncal, because KComponentData doesn't exist yet.

So for now we just store the data in ~/.kdevduchain, and don't support multiple running instances of kdevelop until we find another solution for the locking problem.

Adding / comitting changes to files not yet added to the build system.

I was wrong earlier, c++ makes extensive use of ConstantIntegralType seperate from EnumeratorType, so separate them again.

The full patch looks like it's going to take a while to get right, and with the big changes happening in duchain persistance, I've decided to put them on the backburner for the moment.

added initial stub of kross backend for Lua

Implement loading of KidDraw files. Drawings can now be saved and reloaded again!
Previously saved files (within the past 24 hours or so) are incompatible due to a minor change in the drawingwriter.

Starting flashcard mode.

Some work on integrating parley and parleypractice:
PPMainWindow now can have a KEduVocDocument in its ctor
Parley listens for signalPracticeFinished to reopen -- crash bug partially fixed. I'll work on it more.
New generic button class.

Small theme_reqs change

implement an "Open" action to allow to open local kvtml files and play with them

Implement round robin algorithm for fetching tiles.
This was brought up by the OpenStreetMap tile server admins and should go into 4.1 as well.

Add an action to download an image from the Sloan Digital Sky Survey to the popup menu. It replaces one of the two Digitized Sky Survey actions.

Improve the concept of "priorities" for image loading and employ all CPUs we have for image decoding (nice speedup on SMP machines)

The text editor in the annotation dialog now offers spell checking again - actually it is a completely new widget.

Step 1 done!!
GalleryExport compiles and links!!

Time to move into extragear/graphics/kipi-plugins..

allow to open a directory to batch process all the raw file inside

now it uses the konqueror bookmarks
it tries to sync them in realtime if they are changed from konqueror, a bit bovine atm :) and subfolders still missing

Add support for new svg elements: <a>, <script>, <title>, <desc>

create our own very-minimal containment
it doesn't have any of the actions that don't work

the default corona layout now uses this containment and a clock, instead of defaultdesktop and folderview.

a dbus interface for plasma, and proper stacking
plasma can be shown and hidden and quit, we can get the winid, and we can make it stay above the screensaver. yay! :)

now if only I knew why I got kcheckpass working on my laptop but couldn't do the same on my desktop...

make mouse & keyboard input work.
the code for this is a bit ugly in places.

there's one bug: if a config dialog is closed and focus reverts to another config dialog, the only keyboard things that work are esc and enter.

lock plasma regularly, require a password to unlock, and hide config dialogs while locked
still have kbd focus issues with the dialogs after they lose focus

option to enable/disable plasma in the screensaver settings

preliminary support of favicons in bookmarks and history.
uses the favicons dataengine only to download atm, still to be used to actually update them :)

Attempt at data service support.

It compiles, and it doesn't crash plasmaengineexplorer.
No further promises.

how could i have forgotten this?!
version information queryable from code.

support for mouseover animation for buttons (will be disabled in the tabbar)

new themes for the normal button and the mouseover pressed still missing new hints in the tabbar svg will be useful for experiments in PanelSvg

New Nepomuk query service handling persistant queries

Ported Nepomuk search KIO slave to new Nepomuk query service.
Now supporting online updates of the search folders

Let there be animations!
Now when swithing between items in a group they'll slide in/out with animation.
If anyone sees this please test :)

New ToolTip manager that create tool tips easier than before

Added custom colors support.

now animations and press effects works just as expected :)

* basic implementation of javascript window operations (open, move, resize, close)
* fix parents for javascript messages / dialogs

handle downloads (including downloadmanager settings) and unsupported content by webkitpart

Use PanelSvg to draw popup's borders - first step to integrate with plasma theming

also implement the plugin version checks for the other plugin types

highlighting for basic functions/macros/datatypes of SystemC.

It's a c++ based hardware design and verification language.
It's basically a C++ library

Implement smooth scrolling for KStyles

* Added leds svg.
* It works.

first implementation of a browserbar.
Wheel scrolling support enabled to scroll among previews

Added multiple colors to notes because I love colors.

It's alive!

Yes, we now have player controls.
At least the stop button works with Amarok.

Now we are able to display an image on the cube caps.

Allow sorting messages by size.

Allow switching the message sort order also by clicking on columns.
The simple default skin is now 100% backward compatible. Promote some widely used functions to their own ComboBoxUtils namespace.

Also explicit a couple of message sorting options which weren't totally clear since depending on the ThreadLeader setting.

First work on the new contacts conduit.
This is just an empty framework.
Implementation will follow quickly (I hope =o).

Baby steps.
First akonadi code for the contacts conduit.
This should load the contact items of a specified collection.

Also allow the german leading quote mark ( Unicode character 0x201C ) as a separator for template quotes. This fixes replies and forwards being empty when running under German locale.

Thanks to Friedrich Kröner for figuring out that this bug was locale-dependent (no wonder we developers couldn't reproduce it).

When translating the templates of KMail, please only use U+0022 or U+201C to translate the quotation mark, otherwise you'll trigger this bug.
Simply using the ASCII " character is the best.

Now vertical borders are also generated (fully and partial).
The last thing which is missing for generating is joined cells.

reworked toolbar for the tools, now we got 4 buttons in the toolbar from these one can select all possible tools they are grouped as compile, view, convert, quick

the crash in the config dialog is not related to this commmit (I already checked)

I was bored of XML, yay more work on effects!, enable the reverse effects and add them.

Ink depletion through UI with KCurve works.

Last commit in no SoC-related task for now :P.
Added 2 new effects: miscShape and Eye, now we'are almost complete, all is missing is the heart, i'll request help from any artistic soul that could help me with the heart shape.

Here is a first draft code to save lists.
I don't think I can write any simpler code for this task. It supports nested lists, but I still have to test a few things...

And it doesn't save the list styles, what a shame for something that took less than 45 minutes to be written... :)

(BTW, personnal message to dipesh who will read this : as you can see, I'm not sleeping ;) )

Ok, now, we have ***basic*** support for saving list styles...
I said basic.

Well, primitive would perhaps be more adequate...
Anyway, it's working, that's what matters.

Make the KSpread and HTML renderer use KIO for greater transparency.

* began working on authorization framework

Implement support for paragraphs which span more than one shape (actually 1 or 2 shapes right now, but larger numbers should now be easy to do).

This introduced a few small bugs which need to be fixed, but the tool should still be stable and usable.

Introducing the "Albums" context view applet, which displays a listing of all albums by the current artist. WIP.

Screenshot: <a href="/issues/2008-07-20/files/a2-albums-applet.jpeg">http://www.sebruiz.net/images/a2-albums-applet.jpeg</a>;

Added generation of strings parsable by TagGuesser, just a little bit more and we'll be able to edit tags.

UI fixes and improvements.
Also, as suggested, I made "Dynamic Playlists" the default tab, please let me know if you disagree with this.

Deleting tracks, one at a time for now, implemented for Ipods.

Harmony can now be enabled/disabled via the menu bar in the service browser.
Also, a config change of some sort.
The thread handling is hackish thanks to the magic of glib/qt. <3

Changed RemoveCapabilityIpod to more generic CustomActionsCapability iPod.

Added action to "disconnect iPod," which just removes the collection, but allows you to eject the iPod without eject claiming it's in use. Only accessible by right-clicking individual track at the moment... bear with me.

warning--, added some methods to make albums applet works with nepomuk

The daemon is now a QCoreApplication, so it doesn't have any overhead due to gui stuffs.
Also, dbus registering is working correctly and you can start/stop the daemon via dbus.

(very) basic cover support (no local caching yet)

The daemon now accepts clients to hand off signals to.
Also, harmony is built seperate from the locker. So in case someone doesn't have harmony deps they can still enjoy the regular locker features.

More work on the Handler.
It can start and stop the daemon process now.
Added a menu bar to the mp3tunes service to make starting/stopping easy.

CollectionFactory classes should be in charge of dealing with Collection classes, and nothing else.

Introducing the MediaDeviceMonitor, another layer on top the MediaDeviceCache and Solid, which takes care of lower-level hardware detection, connection, and disconnection.

Media Device Collection classes plug into it and seamlessly get the needed information to build Collections, without doing dirty work. See IpodCollection for reference implementation.

a working start of a "Script Console" script using the Qt Bindings.
Basically its speedcrunch/irb for the amarok scripting system.
Requires you uncomment the generator at the top of amarok/CMakeLists.txt

Added playback of DVD Isos
Thanks to Duns Ens.

Allow spell-checking on html/rtf text.
Save spellchecker settings for every chat window.
Use global spellchecker settings (enable/disable).

Patch checked and updated by Dennis Nienhüser.

Support the new dbus interface of amarok 2.0.
Backport of commits 832447 and 832450, will be in KDE 4.1.0.

* Removed some debug information from client.cpp;
* Added first parts of raw-udp transport support. (Still some to do);
* Added a start session button for testing (This should go away later).

Add a contact list model class for the contact list.
Make it handle the signals that are sent for the addition of groups and metacontacts. (It will handle a few more things in the future).

Provide the current tree view in use with an instance of the new model so we actually have some sort of contact list to work with.

Make starting chats work.

This took entirely way too long, but starting a new chat from the model view contact list is working now.
Time to merge. ;)

Add coloring of metacontacts when they go idle.

If a metacontact is idle, color the item text gray.
Coloring of the icons will be added back once there are more icons to display

Allow items to be dragged and to be drop targets.

This is the start of drag and drop support for the new contact list.
In order to enable drag and drop, we need to allow the model to tell the view that we have draggable items.

krdc: NX support

Start of IP filter revamp.

Note: IP filter plugin is disabled for now, it still needs to be fixed

Added support for emulecollection files.

Gioacchino: Forgive me for not using the work done on Kollektion, but its imho much easier to just implement that functionality direct in KMLDonkey using C++.

Though for creating such *emulecollection-files Kollektion is still the better way (as in KMLDonkey doesn't support it ;)

Finished revamp of IPFilter stuff, also added auto update ability

Another redo of windec buttons, which looks like the older ones, except that they scale better now

Animate change of desktop by activating and rotating the cube.

PackageKit BackendPlugin, initial code, only can get Package Groups now.

We have something working again.
Compiles and runs on KDE4.

Wizard and EditMode is still slightly broken

Silently lay the foundations for pattern plugins with a complete redesign of the Pattern classes.
* The old base class Pattern is split into two parts: PatternConfiguration specifies handles the whole user interaction part (values which have to be entered by the user or are read from and written to savegames). (This class will later be the one that is created by KPluginFactory.) When enough information has been given, the PatternConfiguration object creates a Pattern object which actually does the work of splitting the image into pieces with neighbor relations.

* The Pattern and PatternConfiguration base classes offer full abstraction of the features offered by Palapeli core. For example, the new implementation of the rectangular pattern in pattern-rectangular.[cpp|h] does only depend on pattern.h and pattern-configuration.h.

IMPORTANT: The new code is not yet included in the build. Actually, this is more or less a brain dump of this evening's work. (That means I do not even know if it compiles, but I'm quite sure that the logic is correct.) To get it to work, I need to do a new "New game" dialog and modify the Manager class a bit.
Wow, I'm quite talkative today...

Make new library libpalapelicore which includes all functionality of Palapeli.
The application palapeli itself does now only consist of a single code file which creates a KApplication and passes control to libpalapelicore.

enhancements of the plot generator:
- removed the ugly X11 and PNG gnuplots terminals
- use enhanced postscript terminal
- use imagemagick to generate the png files (with compression)
- disable the fortran impl by default since it is as meaningless as a "C impl"
- update line settings

I couldn't stand the terrible performance of the standard output view any longer.

Change the scrolling to bottom feature to use a delay (100ms chosen to start with)

Alleviates the worst of the lockups (eg, 20s lockup on my quad core2 machine) during output view spamming, but makes it look a bit strange.

Definitive solution still required.

Writing the database once after file copying is over is enough.
Dramatic performance increase.

Keep application responsive while creating pieces (this also creates a nice animation for large piece counts ;-). When game starts, resize viewport to show the entire scene.

Optimization: added super efficient rowmajor * vector product (and vector * colmajor).
It basically performs 4 dot products at once reducing loads of the vector and improving instructions scheduling.

With 3 cache friendly algorithms, we now handle all product configurations with outstanding perf for large matrices.

Moved kdiff3 from playground/devtools to extragear/utils.

* Remove the kdevplatform Ruby extension from KDE 4.1 as it won't be needed until KDE 4.2

trunk is 4.2, feature freeze is over, which means I can now re-enable the snippets plugin that I ported some time ago.

Also include the helloworld plugin in the CMakeLists.txt (but don't build it), so that it won't be so easily forgotten when further interface changes happen.

imported the automatic Qt bindings for Lua

Added theme requirements as a guideline to artists.
This is a non-final version.

Ok, have fun with this - a mockup of how we could puzzle together practices - add your comments everyone

Merging the summer branch into trunk.

This means that:

* KStars now has 2.5 million stars
* There's the coordinate grid clipping trouble at high zoom (so it might be a good idea to disable the coordinate grid)

Removing deepstars.dat from trunk.
It should be shortly added to the Get Hot New Stuff feature for KStars.

start port to KDE4

OK enough time wasted on this statistics dialog, it will likely go away again, but lets keep it around for when we work on the DB backend, as it might be useful for checking that categories and subcategories are converted correctly between backends.

Preload image thumbnails from images in the thumbnail viewer even if they aren't visible yet.

Preloading starts as soon as the ThumbnailWidget knows what images it contains and continues until another bunch of images is to be shown.

This behavior is open for discussion, perhaps it should stop when ThumbnailWidget goes out of (visible) place, perhaps it should only load images that aren't too far from current viewport etc.

Minor change to port the listAllAlbums functionality to KDE4.
Along with this change and changes by others, I verified that uploading functionality works completely on KDE 4.

The plugin also looks great thanks to everyone who helped in porting it.

compile (and kinda work) with KDE4

initial import of darkroom, an experimental raw decoder based on top of libkdcraw

Added some spaces and some FIXME.
This applet is ready to be moved to kdereview :)

adapt keys

Bar -> |
Equal -> =
Minus -> -
Plus -> +
Underscore -> _

and actions

Enable/Disable Clipboard Actions -> clipboard_action
Logout -> Log Out
Logout without Confirmation -> Log Out Without Confirmation
Manually Invoke Action on Current Clipboard -> repeat_action
Show Klipper Popup -> show_klipper_popup
Window Iconify -> Window Minimize

The logout shortcuts also don't work in KDE 3.5.

Integrate the khotkeys redesign.
Currently only global shortcuts are implemented.

Gestures / Conditions will follow later (hopefully before 4.2).

merge in groundwork branch
this creates a plasma-overlay app with its own corona and view

it'll start up fine and load a default desktop containment + folderview
however, once it's hidden you can't bring it back - you have to kquitapp plasma-overlay
the lockprocess will run plasma-overlay when the screensaver starts, but also fails to stop it, and it gets created *under* the screensaver

I'm sure there are a bazillion other bugs - but it does run, and you can add widgets. :)

I don't really want a --nofullscreen flag, I want a --cheats flag.
added a global shortcut to show the view in cheat mode
try keepabove on the view (doesn't seem to help)

KDE 4.1 is supposed to be stable, remove the malloc checker

A first try at a plasma data-engine.

brown paper bag time: this was committed to the 4.1 branch as i used the konsole tab i was doing backports in earlier =/ gurgl.

We want to share more config tabs as possible so we can get an uniform UI and we can code less.

first crack at the design documents thing

now both analog-clock and digital-clock uses shared time zone config code.

A very first plasmoid showing the connected screens.

new theme by Nuno

moved timer plasmoid to kdereview.

Re-enable taskbarthumbnails.
Alexis is working on getting it back.

Disable blue marble plasmoid as it's not in good enough shape to be released

better name; this would bug me eternally ;)

introduce plugin versioning for plasma and ensure that only applets with a matching major.minor version are loaded.

needs porting to plugins other than applets.

let's keep a changelog, why don't we.

exclude from build as kworkspace is excluded as well

this has to be rethought later as kworkspace might be missing on some other platforms too or it might be build sooner or later.

Rename 'license' file to 'LICENSE2'.
Please, never have files with the same filename but different case, that won't work in case-insensitive filesystems (for instance, on Windows).

BTW, I wonder if I can just remove LICENSE2, its contents are the same than those of LICENSE

two different update timeouts: a fast one for simple events, and a slower one for expensive ones. we use the latter for infrequent events and for ones that get repeated a lot (particularly moving windows around).

we use the fast timeout for new windows, closing windows, switching desktops ... results in a much, much more snappy feeling pager without compromising cpu usage for window movement (the original reason i introduced the delay ..)

Merge branch 'kcapacitybar'

Added the demo application which we will use for the Akademy Nepomuk workshop/BoF.

only allow configuration while widgets are unlocked something went wrong, very wrong, when pulling from gitorious.

I don't know what or why. but this is a copy of the last commit I made on my laptop...

bring the tooltip of the trashcan back from the death

automoc in kdelibs is dead since a few weeks

Created KWin branch for window tiling experimentation.

First UI test for the sorting options.
Use a popup menu.
It doesn't look bad :)

Eliminate the Old Month View.
Do not backport.

Added a template for new conduits based on the baseconduit framework.

Move Don Sanders to the former maintainers.

Don, thanks for all the time you spent on KMail.

Add a new section on Hidden Configuration Options and describe the disregardUmask option.

This was originally from a patch Jes Hall sent me well over a year ago.
I'm a bad boy.

Do not backport.

I should stop talking about adjustment layers & be consistent and name them filter layers.
Also explain the word 'sumi-e'.

Interfaces
KoChart::ChartInterface

Detach KSpread and the chart shape from the bridging lib 'koshape'. :)

Why the KChart KPart still needs this lib, I cannot explain.
The embedding in other KOffice apps is done by using the flake library.

Maybe for embedding in external apps?
Either way, that's up to the KChart developers.

Start a small library for common config options for various paintops, such as pressure response things.

Increase systray tooltip timeout to 15s.
Before you start protesting again, this is fine now as we automatically hide the tooltip when the mouse leaves the systray area...

Crossfading is not implemented at this point, so let's simplify the settings dialog.

An attempt at achieving more consistency: Auto-play tracks that are dragged from the collection (if nothing else is playing).

revert current model work in favor of a more defined split between the libkopete stuff and how that stuff is represented in the GUI.

totally decimate the group view item and the metacontact view item.
they're now just thin model item wrappers around their respective objects.

Depend on 3.5; no one cares enough to fix building the documentation against 3.4 again.

Tagging Konversation 1.1rc1.

Make this file the TODO for the contact list branch.

We basically need to reimplement a whole contact list UI

Move Cube effect to trunk

Move pinheiro's last-minute KJots app icon out of core Oxygen and into KJots itself.

Someone (i.e. not me) needs to backport this to 4.1, as we don't want application icons in core Oxygen for various reasons.

New icon first of a 40 set

Fixes, adding barebones of plasma engine

Start documentation for Palapeli pattern plugin API.
Also, optimize RectangularPattern (run time reduced to about 30%).

Who needs atomic commits? Here comes the GIGANTIC commit!!!
Hopefully, this is the last commit in the very long series of "Let's break the total internal infrastructure of Palapeli" commits. (To be honest, I doubt.)

Here are the changes:

* Rename libpalapelicore to libpalapelipattern because everything else is moved back to Palapeli application. This is possible because the Pattern class gets a proper interface to the Palapeli game engine.
* The Palapeli::Pattern::slice function is renamed to Palapeli::Pattern::doSlice, because there is now another non-virtual slice function which does some initialisation in the base class.
* The piece positions are now loaded or randomized in the Palapeli::Pattern class.* Move libpalapelipattern to a separate directory. Do only include this folder in API documentation.

Added initial version of Parsek User Research Profile

Install sounds.
Rename sounds to mark them as sounds for KDiamond.

Complete rewrite of partial reduction according to mailing list discussions.
