Enabling debug logs for Telepathy
When there are certain kinds of problems with collaboration, it is useful to developers to have log files for debugging purposes. Here is how to enable these log files. If you haven't already seen BugSquad/Get Logs, see that page first.
- Edit ~/.sugar/debug and uncomment the lines about GABBLE_DEBUG, GABBLE_LOGFILE, SALUT_DEBUG, SALUT_LOGFILE and PRESENCESERVICE_DEBUG by removing the initial '#' character
- For debugging lower level problems in the Telepathy connection managers, enable LM_DEBUG (for telepathy-gabble) or GIBBER_DEBUG (for telepathy-salut). Note that these will produce much bigger log files.
- Reboot
Telepathy log files are now available at ~/.sugar/default/logs/telepathy-gabble.log and ~/.sugar/default/logs/telepathy-salut.log . Be sure to attach these files if you submit a ticket about a Telepathy issue.
Capturing core files (XO specific)
Core files are produced when a program crashes and contain useful debugging information. By default, core files are disabled on the XO. Here is how to enable them.
- As root:
echo /tmp/core-%p-%e > /proc/sys/kernel/core_pattern
- This tells the kernel to put core files into the /tmp directory. This will only be effective until the laptop is rebooted. To make it persistent across reboots, add the following line to /etc/sysctl.conf:
kernel.core_pattern = /tmp/core-%p-%e
- Add the following line to ./sugar/debug:
ulimit -c unlimited
This turns off any limit on core file size.
Debugging scenarios
XXX
- no presence seen on (or of) other machines/laptops
- activity was shared but doesn't appear on other laptops
- invitation was sent but not received
- other sharing problems
