Weekly Report #3: Recipe for the perfect disaster

First of all the GSoC weekly report news:

Yes, I know this is not kinda “weekly report”, but, as I’ve already told to my mentor, I’m quite busy in these days because I’ve an exam on June 25. However, step by step, I’m solving the main “behind-the-scenes” difficulties of the project.

SVG markers and patterns

As you can see in the image above, now, when a class is selected, if it contains a reference to an SVG marker contained in the rule file, the marker is shown on the right. Not quite beautiful yet, but it works. The following is another example, even if more difficult to read:

Because I’ve not already upgraded my Linux box to Firefox 3, I couldn’t take a snapshot showing SVG patterns (which are supported by my code as well), because SVG patterns aren’t supported in Firefox 2, as also stated in MDC. However it works smoothly on Firefox 3 for Windows.

Rules Modeling

Beyond SVG markers and patterns, I’ve got progress in rules handling too. Now quite all rules are parsed (think only “tag” elements inside “text” elements aren’t handled yet; same for selectors too), and class/mask-class parse-to-arrays is working.

As you can see in the above picture, if we search in the rules for “tunnel-core” class, the correct rule is shown even if tunnel-core is a mask-class and not a real class in the rule file.

Else elements are handled as well:

So what about the recipe for a perfect disaster?

That’s simple:

  • Take a laptop computer, Windows XP/Kubuntu 8.04 dual boot
  • Edit three critical GSoC project files in the Windows XP FAT32 partition for a while with Aptana
  • Go to dentist without powering off the computer
  • Return at home, find the pc powered off, power on it, go to Kubuntu and edit three critical GSoC project files in the Windows XP FAT32 partition for a while with KWrite
  • The day after, boot to Windows XP to read some notes rapidly
  • Find it was suspended, see Aptana still open with that three files.
  • Close Aptana without closing the three most critical files of the project before
  • Power off the PC and, during the evening, boot to Kubuntu
  • Find the wireless is not working, so reboot Kubuntu again
  • Leave the laptop booting, and find after a while the dosfsck has run and fixed automatically something in the FAT32 partition
  • Open Dolphin and, finally, cry looking at the following screen

Obviously I had a backup, but several hours of work got wasted however… Sic!
