# In very old (e.g. 1.1.54385) versions of ClickHouse there was a bug in Poco HTTP library:
# Basic HTTP authentication headers was not parsed if the size of URL is exactly 4077 + something bytes.
# So, the user may get authentication error if valid credentials are passed.
# This is a minor issue because it does not have security implications (at worse the user will be not allowed to access).
CUR_DIR = $( cd " $( dirname " ${ BASH_SOURCE [0] } " ) " && pwd )
# shellcheck source=../shell_config.sh
. " $CUR_DIR " /../shell_config.sh
# In this test we do the opposite: passing the invalid credentials while server is accepting default user without a password.
# And if the bug exists, they will be ignored (treat as empty credentials) and query succeed.
