# 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.
