---------------------------------------
Summary: Add support for verifying multiline log entry
Key: HDDS-1889
URL: https://issues.apache.org/jira/browse/HDDS-1889
Project: Hadoop Distributed Data Store
Issue Type: Test
Components: test
Reporter: Dinesh Chitlangia
This jira aims to test the failure scenario where a multi-line stack trace will
be added in the audit log. Currently, for test assumes that even in failure
scenario we don't have multi-line log entry.
Example:
{code:java}
private static final AuditMessage READ_FAIL_MSG =
new AuditMessage.Builder()
.setUser("john")
.atIp("192.168.0.1")
.forOperation(DummyAction.READ_VOLUME.name())
.withParams(PARAMS)
.withResult(FAILURE)
.withException(null).build();
{code}
Therefore in verifyLog() we only compare for first line of the log file with
the expected message.
The test would fail if in future someone were to create a scenario with
multi-line log entry.
1. Update READ_FAIL_MSG so that it has multiple lines of Exception stack trace.
This is what multi-line log entry could look like:
{code:java}
ERROR | OMAudit | user=dchitlangia | ip=127.0.0.1 | op=GET_ACL
{volume=volume80100, bucket=bucket83878, key=null, aclType=CREATE,
resourceType=volume, storeType=ozone} | ret=FAILURE
org.apache.hadoop.ozone.om.exceptions.OMException: User dchitlangia doesn't
have CREATE permission to access volume

2. Update verifyLog method to accept variable number of arguments.
3. Update the assertion so that it compares beyond the first line when the
expected in a multi-line log entry.
{code:java}
assertTrue(expected.equalsIgnoreCase(lines.get(0)));
{code}
