What are the logs useful for
If you provide debugging logs to a ticket, you'll be making it much easier to developers to fix the issue. In most of the cases it will be easiest for you to reproduce the bug.
Enabling debugging
These are general steps to follow when providing logs for some bug:
- Start the Terminal activity.
- Type the following:
echo 'export SUGAR_LOGGER_LEVEL=debug' >> /home/olpc/.xsession
- Reboot, or just restart X using ctrl+alt+erase
Where are the logs placed
- Perform the minimal steps to reproduce the bug.
- The relevant logs are in /home/olpc/.sugar/default/logs, (e.g org.laptop.WebActivity-1.log for the log of the first Browse instance).
Attach the logs
The easiest way is to use the Browse activity to attach them to the ticket. You can copy them to a USB flash drive and attach them to the ticket from another computer as well.
Note: The file datastore.log may contain a list of all the files in your USB flash drive or SD card. Check and delete from there if you don't want to submit that information. Most probably it's not needed by the developers.
- You may also use
olpc-netlogto gather all logs and XO info into a single file. - Log is an activity for viewing log files
Other debugging settings
The file /home/olpc/.xsession-example contains other settings useful for debugging. You can copy individual lines from this or copy the entire file to /home/olpc/.xsession.
Presence service
If your bug involves the presence service, you might also want to follow the steps for BugSquad/TelepathyDebugging.
If you can't reproduce the bug
Python-based activities automatically make logs in /home/olpc/.sugar/default/logs. These logs seem to be moved into subfolders on restart and deleted after a certain period of time. The python stack trace is recorded here on crashes. This is also a good thing to attach to a bug. As above, you will have to use the Terminal activity to copy them to removable memory (SD or USB) before using the XO or another computer to attach them to the bug.
