Vivek – Messaging strategies

see on wiki: Grouper Messaging System

• Move pspng to messaging?

• Issue with ack’ing and rabbitmq and activemq

• Messaging is similar to change log but you can selectively ack

• Do we need a mode where we say we will ack it?

• Can get 20 messages at a time (AWS lowest common denominator), should we look at adjusting that?
• Next step for Vivek would be to write a WS listener to translate messages to rest.  Can have a reply to and a UUID.  We can do a design doc


Chris –patches, attestation, deprovisioning
• Hope to have deprovisioning patch by next Grouper call

Bert – PSPNG
• DN and filter escaping work, will have patch

• NYU use case

◦ Patch 13 worked for some situations , but not for all (issues around bushy)

◦ Patch 14 will fix that

• Multiple group object classes

Shilen –GSH-NG

see on wikiImprove GSH 

• Backspace, because of term?  Able to reproduce

• If run groovysh natively then it doesn’t happen

• Jline version that is shipped natively is an older version, the older version doesn’t have that problem

• Ship with the older version?  Yes

• Chris will test the patch
