Issue #8203 describes a bug in a long scan which returns a lot of empty
pages (e.g., because most of the results are filtered out). We have two
cql-pytest test cases that reproduced this bug - one for a whole-table
scan and one for a single-partition scan.
It turned out that the bug was not in the Scylla server, but actually in
the Python driver which incorrectly stopped the iteration after an empty
page even though this page did contain the "more pages" flag.
This driver bug was already fixed in the Datastax driver (see
6ed53d9f70,
and in the Scylla fork of the driver:
1d9077d3f4
So in this patch we drop the XFAIL, and if the driver is not new enough
to contain this fix - the test is skipped.
Since our Jenkins machines have the latest Scylla fork of the driver and
it already contains this fix, these tests will not be skipped - and will
run and should pass. Developers who run these tests on their development
machine will see these tests either passing or skipped - depending on
which version of the driver they have installed.
Closes#8203
