Hi,
It could also be the case, that carrierroute uses Rawquery, which is not
supported by all database modules. However, when using db_cluster, the
db_cluster module claims to support "any" DB operation, even though the
underlying db-module may not support all DB operations.
Thanks,
Carsten

Hello,
if you can not reproduce it with db_mysql, it might be indeed some issue
specific related to sqlite. Executing the tests with debug log level should
give you more information about the internal database operations, in case
you like to look more into it.
Cheers,
Henning

I cannot reproduce this issue against mysql, so perhaps it is just
something related to abstraction and concurrent access with sqlite.

All,
I’ve been trying to chase down an issue with db_cluster and permissions in
combination with something else, where with my full configuration using the
same cluster in multiple modules has failures. I’ve been trying to create
a simplified configuration to consistently reproduce the problem without
much success, however I did stumble upon THIS particular problem. The
configuration here works fine as is – avpops uses the cluster URL, and
carrierroute uses the direct SQLite URL. If I define WITH_DBCLUSTER, then
carrierroute fails fetching rows using the cluster connection. Note that
AVPOPS is only used as a general test to see if the cluster config works.
If I remove references to avpops , carrierroute still fails loading from
the cluster URL. Thoughts?
