cf_client_data duplicating and not deleting

Fixed

Description

We are seeing two issues with our new Lucee 5.3.8.189 implementation.

1) Duplicate entries in the cf_client_data. One entry with the appropriate Application Name (as defined in Application.cfm), and a 2nd entry (that looks identical) but has Name = Null.

2) We've set our session variables (including Client) to expire in 1 hour. After 4 days, we have 130,000 records in this table. An inspection of the "expires" variable shows that data is not being deleted.

Background: https://dev.lucee.org/t/client-variables-database-millions-of-entries/8520/5

Environment

Lucee 5.3.8.189
Apache Tomcat/9.0.35
11.0.7 (AdoptOpenJDK) 64bit
Linux (4.18.0-305.7.1.el8_4.x86_64) 64bit / CentOS Linux 8.4.2105

Thanks for your help Zac.

After studying it some more this morning, I noticed two context defined in Lucee Admin. One from our application, and one from /opt/lucee/tomcat/webapps/ROOT (maybe a default?)ā€¦

Iā€™m wondering if the null values are coming from there - which would be a configuration issue on our end.

I can only reproduce this by using an Application.cfc without a name, as Terry commented on the mailing list

Following up on this. The fix definitely stopped the table from growing endlessly. Records are now being purged again hourly (as they should be).

However, I still see double-entries in the cf_client_data table. One with the appropriate Application Name - and a 2nd entry with a NULL value for the Application Name. This is causing performance issues for our very high volume application.

Yep

Hey guys - If I update to 5.3.8.201, is this fix included?
