--------------------------------------
Summary: Audit log omits the create mode of sequential and TTL
nodes created in a multi
Key: ZOOKEEPER-5107
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-5107
Project: ZooKeeper
Issue Type: Bug
Components: audit
Affects Versions: 3.10.0, 3.8.7, 3.9.6
Reporter: Jialin Chen
Assignee: Mohammad Arshad
For the creates inside a {{multi}}, {{AuditHelper}} looks up the create mode in
a map keyed by the requested path. The lookup misses for sequential nodes,
because the result carries the actual path ({{/node-0000000005}}) rather than
the requested one ({{/node-}}), and for TTL nodes, because {{createTTL}} ops
are never put into the map. Those audit entries are written without
{{znode_type}}.
Steps to reproduce (standalone server built from master at 48f7cb00e, started
with {{-Dzookeeper.audit.enable=true -Dzookeeper.extendedTypesEnabled=true}}):
one {{multi}} creating {{/m-plain}} (PERSISTENT), {{/m-seq-}}
(PERSISTENT_SEQUENTIAL), {{/m-ttl}} (PERSISTENT_WITH_TTL) and {{/m-eph}}
(EPHEMERAL).
Actual audit entries:
{noformat}
operation=create znode=/m-plain znode_type=persistent result=success
operation=create znode=/m-seq-0000000005 result=success
operation=create znode=/m-ttl result=success
operation=create znode=/m-eph znode_type=ephemeral result=success
{noformat}
Expected: {{znode_type=persistent_sequential}} and
{{znode_type=persistent_with_ttl}} on the second and third entries, as for the
same creates outside a {{multi}} (the TTL case since ZOOKEEPER-4725).
The path lookup dates back to the introduction of the audit log in
ZOOKEEPER-1260 (3.6.0).
