# title: Sweep could raise error : page 0 is of wrong type (expected 6, found 1)
# decription:
# Test receives content of firebird.log _before_ and _after_ running query that is show in the ticket.
# Then we compare these two files.
# Difference between them should relate ONLY to sweep start and finish details, and NOT about page wrong type.
#
# Checked on: WI-V2.5.7.27024, WI-V3.0.1.32570, WI-T4.0.0.316 -- all works OK.
# Refactored 01.02.2020, checked on:
# 4.0.0.1759 SS: 4.754s.
# 3.0.6.33240 SS: 3.704s.
# 2.5.9.27119 SS: 6.607s.
