Work on Decibel and the KDE-based NEPOMUK components accelerates. The Unity web rendering engine experiment is removed from KDE SVN, due to a change in the circumstances that prompted its creation. KTabEdit, a guitar tablature editor is imported into the KDE SVN playground. A branch of kde-pim for improvements in future 3.5 releases shows promise with the introduction of several new features. QMA, an experimental email client, continues to mature and is renamed Mailody. Usability and file format support refinements in Amarok. Speed optimisations in KViewShell and KFTPGrabber. More improvements in the state of games in KDE 4.

Ian Ventura-Whiting introduces the three database tools imported into KDE SVN last week:
|
Even though the Kexi team, as well as others, are adding some excellent database tools to KDE, ODBC support is one area that is still poorly supported. ODBC is used in a wide variety of business applications and is a key requirement for more advanced users. I have been working on a number of tools to help bridge this gap and plan to work closely with developers of other KDE database tools.
The first program, Data Sources, is a tool for configuring ODBC drivers and data sources. Users of similar tools on other platforms will be pleased to see how similar this tool looks, feels and operates. Data Sources makes things even simpler, with auto-detection of missing ODBC drivers and wizard-based configuration. It also shows users only the options needed to configure a data source, whilst advanced configuration options are still accessbile. At the moment, the program is a fully working Qt 4.2-based application and I intend to move it into a KCM module. (Currently located at trunk/playground/base/datasources, screenshot)
SQL Query, as the name suggests, is a tool for querying databases. It allows a user to open ODBC data sources, or use the Qt database drivers. Users can browse databases, execute SQL statements or run SQL scripts. I plan to add many more features to this program, including importing and exporting database data. This program is currently Qt 4-based and I intend to make use of the KDE 4 libraries, add syntax highlighing to the SQL editor and add other important functionality. (Currently in trunk/playground/office/sqlquery, screenshot)
The last tool, ODBC Statistics, is a small tool for monitoring ODBC connections. (Currently in trunk/playground/sysadmin/odbcstats)

The past weekend saw the second bug triage day, concentrating on the kde-pim module. This follows on from the highly-effective first bug triage day which targeted Konqueror several weeks ago.
To gauge the scale of the existing bug mountain, there are approximately 2600 open bugs registered against KMail, with a further 700 outstanding in KOrganizer. With the bug-crushing effort on Saturday, Will Stephenson reports that there were over 40 people in the co-ordinating IRC channel (#kde-bugs) at the peak of the bug-fixing zeal, with many non-programmers using their talents with good effect.
With two successful events now completed, we will surely see a fresh announcement and challenge within a few weeks - which part of KDE should fear the wrath of the KDE Bug Squad next?

David Faure übertrug eine Änderung für /branches/KDE/3.5/kdelibs/kio/kio/kmimetype.cpp:
|
Patch from Modestas Vainius to fix Bug 122020 (kdesvnd action menu issues)
He said, and I agree:
Do not time out when waiting for the reply for the X-KDE-GetActionMenu DCOP call. DCOP protocol is synchronouos by design and a reply for the timed out call (i.e. garbage) still arrives and might be falsely returned as a valid reply for the subsequent DCOP call on the same connection. The application currently known to be badly hurt by this is kdesvn and its konqueror service menu integration. Its X-KDE-GetActionMenu might take longer than current 100 milisecond timeout to complete. As a result then, a late reply will "pollute" a main DCOP connection of the client application (e.g. konqueror) causing further DCOP failures. |

Prevent crash-inducing recursion of detach due to blur events
happening when widgets with focus get destroyed, by quietly shifting
the focus to the view...(#135384, probably #124342 --- best I can tell given
imperfect information); also affects some bugs which I separately closed as
non-reproducible, but which involved such a sequence
Also fixes freezing in #92497, as we no longer try to find something
to focus when nothing is focusable.. |

More ruby parser improvements:
- recognize comments
- recognize scoped names (ala Foo::Bar ) as proper module names
- recognize ruby symbols
- recognize if/unless/while/until statement modifiers
- two consecutive method calls without parens are no longer parsed as one statement
Now the parser understands pretty sophisticated ruby programs! |

Jason Harris machte Änderungen in /trunk/KDE/kdeedu/libkdeedu/kdeeduplot:

Implementing non-colliding text labels in kdeeduplot, based on kmplot code.
It works, but it could probably be faster. You don't need to know anything about it to use the feature, it all happens behind the scenes. Just add some items with labels and enjoy the magic.
However, in the interest of inspiring optimization, here's a brief description of how it works.
KPlotWidget now has a private array of floats: PlotMask[100][100]. This is a rough division of the content of the plot into a 100x100 grid. Where the plot is empty, the array is zero, where it has content, it is >0. When items are added to the plot (points, lines, bars, or labels), the corresponding positions in PlotMask are incremented by an amount that can vary for different kinds of items (for example, right now Bars don't increment as much as points or lines).
The function KPlotWidget::placeLabel() is responsible for positioning item labels. It attempts to place the label close to the point to which it belongs, while minimizing the label's overlap with masked regions of the plot. Ideally, it won't overlap with masked regions at all. This is done in a rather brute-force way: it tests label positions in a 40x40 grid around the position of the point, and determines the "cost" for placing the label at each position. Higher cost is incurred for (a) overlapping with a masked region, (b) being further from the point position, and (c) extending beyond the bounds of the plot. The position that has the lowest "cost" is then adopted, and the label is drawn at that position.
You can get an idea of the CPU impact of this cost-analysis using the test suite I added to kdeeduplot. Display the "Points, lines and bars" plot, and then resize the window. Note the smoothness of the redraws. Now display "Points, lines and bars with labels" and resize the window. The redraws take much longer in this case. |

New template goodies from Dmitry:
1. Conversion phrases into templates
2. Per-identity templates
3. Templates are used also with multi-message forward (was missed)
4. C-style correction of templatesconfigurationimpl.cpp
5. Minimal and default sizes of templates configuration widget diminished a
little; folder properties are not so huge now.
6. Several commands added: %CCADDR, %CCNAME, %CCFNAME, %CCLNAME, %OCCADDR, %OCCNAME, %OCCFNAME, %OCCLNAME
Please continue testing templates.
Great work Dmitry! Glad to have you helping with KMail.

New class;
we need a better way to do progress notification for various actions.
A simple usecase is a user action or filter that can be split into multiple
subactions which each have their independent progress indication.
We want to show the total progress in a progressBar.
This new class does that and all of the following features:
* threadsafe
* be able to handle more than one concurrent action
* be safe
* be cancelable
* non-modal
* be fast
* be really easy to use |

After a lot of preparation, finally removed full redraw at every tile addition and removal. There is still some room for optimization, but at 800x600 play area the game is now using less than 1% of a 2GHz cpu, with minimal redrawings.
Unfortunately, this change is for KDE4 only and can not be backported to 3.5.x series. |

Wilfried Huss machte Änderungen in /branches/work/kviewshell-0.7/kviewshell/shell:

Optimizations of the Thumbnail list.
We now only create thumbnail widgets for thumbnails that are really visible in the viewport. That means we need to create only a very small number of widgets, and not one widget per page as before.
This gives a huge performance boost for all operations, expecially loading and closing of documents, and rotating the view, since the creation and especially deletion of QWidgets is quite slow.
The performance gain is only noticable for very large documents with 1000 or more pages.
There are still a few little regressions, which I will fix later. |

Frans Englich machte Änderungen in /trunk/kdenonbeta/kdom/patternist:
|
Dump dependency on QtGui by not using Qt::escape. This makes libpatternist link to about half as many libraries.
Some things are, pardon my french, hard to understand in Qt, in my eyes. Qt::escape(), a practical little helper function for escaping text, is placed in the Qt namespace but then in the QTextDocument header, as opposed to QtGlobal. Implicitly, a function that has nothing to do with GUI, is placed in QtGui, creating a dependency on a whole new library for only that function.
Same goes for QAbstractProxyModel. The item/view framework provides a nice separation between content and presentation, but by placing QAbstractProxyModel, a class that operates on the data level independently of display details (right?), in QtGui, one again prevents modularization.
The argument I've heard is that QtCore is supposed to stay small, but I wonder if such optimizations(can Qt::escape() and QAbstractProxyModel really be considered big?) are more worth than proper engineering. |

Thiago Macieira übertrug eine Änderung für /trunk/KDE/kdebase/workspace/startkde:
|
Use a slightly more intelligent way of detecting whether the D-Bus daemon is running: instead of trying to kill -0 it, try to connect to its address (using qdbus).
This has the added benefit that it works with the autolaunch method that was introduced with D-Bus 0.94. If you're using 0.94, you no longer need to run "eval `dbus-launch --auto-syntax`" before starting your KDE4 applications (this is valid for individual applications, not just startkde).
Note: this requires qdbus to be in your $PATH. But everyone has Qt 4.2's bindir there, right? |
