Navit slows down dramatically if POI icons are not found

Reported by: la7qz om Owned by: KaZeR
Priority: critical Milestone:
Component: core Version: git master
Severity: Keywords:



I recently had an issue after installing a new map layout when Navit slowed down to the point of being unresponsive.

After starting Navit from a terminal I discovered the problem was that the links to the POI icons was broken in the layout I had installed. The reason Navit was slowing down was that it was repeatedly attempting and failing to load the same POI icons. I assume once per occurrence of that particular type of ICON on the map.

My suggestion is that when loading a POI icon has failed, a flag should be set and Navit no longer attempts to load that icon. If more than three different POI icons fail to load, a second flag could be set and Navit quits all future attempts at loading POI icons for that session.

Some way of notifying the user of what is going on would be useful. Maybe replace missing POI icons with a questionmark on screen at run time and notify the user what happened on exit.

Which platform and graphics driver of navit are you using? Some drivers can already handle this problem.

This is in Ubuntu 11.04 on an Asus Eee900. Not sure what the graphics driver is.

To find the graphics driver, just paste your version of the following lines:

<graphics type="gtk_drawing_area"/>	

<gui type="internal" keyboard="true" enabled="yes" font_size="300">

  • Resolution set to invalid
  • Status changed from new to closed

I tried different routes in Germany with different ranges in car profile but the current SVN doesn't crash. If the bug persists, please reopen this bug. For cleanup reason, I set it to close.

Damn, I mean I tested with broken icon links on linux and wince but there is no slowdown yet anymore.
