  • Debugging Akonadi

    From Martin Steigerwald@21:1/5 to All on Sun Oct 6 20:10:01 2024
    Hi!

    Also as an extra mail with a nice subject, so I or anyone else can more
    easily find it later:

    Sandro told me a nice shortcut on IRC to enable all log output for
    Akonadi:

    `QT_LOGGING_RULES="*.*=true;qt.*=false" akonadictl restart`

    Thanks, Sandro!

    I wrote "start" before, cause I always first stop Akonadi and test
    whether it is really gone. Including the database process. But "restart"
    even in that case can be better cause Akonadi could again be started by something. And now that I am using SQLite3, no database processes to watch
    out for anymore:)

    Ciao,

    Hey,

    `QT_LOGGING_RULES="*.*=true;qt.*=false" akonadictl start`
    ^^ restart does not work here - killed it from a different terminal
    with `akonadictl stop`

    Is it possible to add a TIMESTAMP?

    QT_MESSAGE_PATTERN="[%{time process} %{type}] %{appname} %{category} % {function} - %{message}" QT_LOGGING_RULES="..."

    you have full control about the log format - see the documentation: https://doc.qt.io/qt-6/qtlogging.html#qSetMessagePattern

    btw. you can enable/disable different categories in QT_LOGGING_RULES. I use *.*=true to see everything. Most of the time, if I'm debugging KDEPIM stuff the issue is not inside qt, that's why I disable every qt category (qt.*=false).
    As qt will log very much.
    To see all different logging categories you can run kdebugsettings, you can also use it to modify the logging for your system. BUT ATTENTION: this can fill your log files very fast! That's why I suggest to use QT_LOGGING_RULES for debug exactly one call of a program, if needed.

    regards,

    hefee
