Via Vala's D-Bus support we use GLib's GDBus (on both sides). For read
queries depending on access level to meta.db we use SQLite WAL journal
for a direct connection with the meta.db.

I think your seteuid() to drop to the user-ID from root should be
called from your code rather than in libtracker-sparql.

Is there a reason why libtracker-sparql must be adapted?


Happy New Year
