--------------------------------------
Summary: Long Sessions can have a negative duration
Key: UNOMI-927
URL: https://issues.apache.org/jira/browse/UNOMI-927
Project: Apache Unomi
Issue Type: Bug
Components: unomi(-core)
Affects Versions: unomi-3.0.0
Reporter: Jerome Blanchard
When a session duration exceed a certain amount of time (2 or 3 weeks) the
duration can be negative !
Duration of a session is computed by the difference between 2 timestamp which
are long values.
Whereas, in the documentation and in ES mapping config, a Session's duration is
supposed to be a long:
[https://github.com/apache/unomi/blob/15ae3eaca8c640a00df255bb0da781fa55f19fa8/manual/src/main/asciidoc/datamodel.adoc#L503]
Also in the session mapping config for ESS and OS :
[https://github.com/apache/unomi/blob/15ae3eaca8c640a00df255bb0da781fa55f19fa8/persistence-elasticsearch/core/src/main/resources/META-INF/cxs/mappings/session.json#L21]
[https://github.com/apache/unomi/blob/15ae3eaca8c640a00df255bb0da781fa55f19fa8/persistence-opensearch/core/src/main/resources/META-INF/cxs/mappings/session.json#L21]
In Session.java, there is a (int) cast when setting LastEventDate()
[https://github.com/apache/unomi/blob/15ae3eaca8c640a00df255bb0da781fa55f19fa8/api/src/main/java/org/apache/unomi/api/Session.java#L191]
It is also unclear why, in some translation (i18n) entries, it is mentioned
some thresholds for session duration in seconds (even of those entries seems to
not be used) :
[https://github.com/apache/unomi/blob/15ae3eaca8c640a00df255bb0da781fa55f19fa8/plugins/baseplugin/src/main/resources/messages_en.properties#L80]
All duration in persistence are supposed to be milliseconds.
