# BUG#46166: MYSQL_BIN_LOG::new_file_impl is not propagating error
#            when generating new name.
#  
# WHY
# ===
#
# We want to check whether error is reported or not when
# new_file_impl fails (this may happen when rotation is not
# possible because there is some problem finding an 
# unique filename).
#
# HOW
# ===
# 
# Test cases are documented inline.
