fatal: The remote end hung up unexpectedly

Gitorious is getting a bit grumpy at clones and fetches lately, especially with big repositories such as WebKit.

A workaround, as suggested by Simon and the Gitorious support, is simply to use the SSH protocol instead of the Git protocol, even for read-only access to repositories. This requires to have a Gitorious account setup, which most of us should have already.

You can edit your .git/config file to achieve that by changing the line

url = git://gitorious.org/webkit/webkit.git

to

url = git@gitorious.org:webkit/webkit.git

Do the same for the QtWebKit team repository:

url = git@gitorious.org:+qtwebkit-developers/webkit/qtwebkit.git

Gitorious are reporting having difficulties to handle all the traffic they currently have, I guess this may affect the stability of the daemon serving the git:// protocol, who knows.

This week (37) in Oslo

A fast-paced week:

• Andreas and I finished what Vlad had started: QtWebKit trunk can now be built against V8. There's one catch: Not just any V8, it's our experimental evaluation port of QtScript that uses V8. On the upside it means the death of the ugly bridge code and instead QWebFrame::addToJavaScriptWindowObject use QtScript's native QObject bindings. Latest news is that the Web Inspector started working with the V8 build, too.
• Andreas fixed a miter-join bug in Qt's stroker, allowing the removal of ugly workarounds in the Qt port of WebKit. Transparency layers have also received a nice performance boost through the removal of unnecessary clipping.
• Tor Arne is hacking away on the low-end version of the video playback and QtMultimediaKit.
• We had an intense workshop the entire week, focusing on knowledge sharing about WebKit and Qt development and the Symbian port.

This week (36) in Oslo

This week's highlights from Oslo:

• Integrated Juha's awesome fix for SSL hangs on Symbian into Qt 4.7.
• V8 evaluation for QtScript continues at fast pace, as well as Andreas' work on massaging Vlad's patches to build QtWebKit with V8.
• More preparations for Symbian/WebKit/Qt workshop in Oslo in Week 37
• Tor Arne is refactoring the mediaelement fullscreen  branch to work better on different platforms with different graphics architectures, as well as fixing bugs in QtMultimediaKit.
• Jocelyn found and fixed a bug in QNetworkAccessManager's internals, improving the network stability when loading many websites consecutively.
• Benjamin has - among many other things - fixed auto-test failures with QtWebKit on Maemo/arm.

blur support for CSS and Canvas shadow

Lately I have been working on adding blur support for CSS and Canvas, see master bug 34479. It is using Gaussian blur approximation via successive box blurs (I wrote detailed info on how it works and performs).

This is still work-in-progress, although it already allows QtWebKit to show soft shadow for text:

as well as, like Andreas mentioned, nice effect on Canvas demo Parcycle:

Installing Qt in parallel on Symbian

Jocelyn just gave me time-saving important advice:

If you're building Qt with an infix to be able to install Qt in parallel on a Symbian device, then you may run into the problem that the installation of QtMyInfix.sis fails. The error message is usually "General OS-related error", which tells us clearly what's wrong. NOT ;)

One likely source of error is a file conflict. The way to fix this is to look at the Qt_template.pkg file and comment out any files and directories that do not have your infix in the name. For example some of the qml directories are not infixed and they exist already on the device, so just comment it out in the .pkg file with a semi-colon and then it'll install.

It's a bit of trial-and-error, but for the time being it works :)

This week (35) in Oslo

Back to a weekly rhythm:

• We're ramping up on our technical evaluation of V8 for QtScript. Olivier joined (yay).
• We're preparing hardware/software for a Qt/Symbian/WebKit workshop in Oslo.
• Jocelyn - our Symbian Knight - has been debugging network load issues with Qt/QtWebKit.
• Andreas started reviewing Vlad's V8-for-QtWebKit patches, so that we can find out how QtWebKit would work with V8.
• Qt Developer Days are coming up, so some of us have been busy preparing presentations.
• Benjamin is investigating clipping performance with WebKit and the OpenGL paint engine, but as usual we often come back to the conclusion of wanting raster. (update: It seems scissor clipping was disabled)
• Hangs with SSL on Symbian are also giving us headaches. A guy from Digia was able to reproduce it and is helping out. Yay :)

Installing the Crash Analyser in Carbide

Jocelyn ran into this yesterday, I ran into it, too. The future reference in this searchable archive:

If your Carbide installation lacks the Crash Analyser (in the Carbide Menu), here's how to install it:

• Upgrade to Carbide >= 2.6. You can use Help->Check For Updates to upgrade your existing installation in place. Works beautifully :)
• Help -> Install New Software
• Select the Carbide C++ Update Site under "Work with:"
• Select the Crash Analyser in the list of available software
• Next and Finish :)
