Description Murray Cumming 2012-02-02 11:25:59 UTC 
Created attachment 206614 [details]
gda_meta_tables_fails_as_lesser_user.c

This test case shows that gda_connection_get_meta_store_data() can return an empty GdaDataModel for GDA_CONNECTION_META_TABLES, though no error or other warning is shown.

This happens with a non-superuser user that I add in Glom, and is also seen in this Glom test case, which creates the user and then tries to use it:
http://git.gnome.org/browse/glom/tree/tests/test_selfhosting_new_from_example_operator.cc

I am still investigating to find out what about the user triggers this, but I though someone else might know where in the code an error is maybe not checked for properly.
Comment 1 Murray Cumming 2012-02-03 10:43:11 UTC 
Actually, this was caused by none of the tables having the "GRANT SELECT" privilege. I am surprised that this also means that the table's existence cannot even be discovered, but maybe it's intentional and unavoidable.
Comment 2 malerba 2012-02-05 21:15:47 UTC 
I think this is intentional.
