Quick Notes / Reminders
- NEXT DSpace 7 UI MEETING: TOMORROW, Aug 17 at 15:00 UTC (11:00am EDT) in Google Hangouts
- DSpace 7 Working Group (2016-2023) - Watch this page for initial ongoing updates on meetings, etc.
- Tim will be out next Tues / Weds, attending the DSpace User Group meeting at Georgetown. (Terry Brady & Mark Wood will also be at this meeting)
- Do we want to cancel next week's DevMtg (Aug 23 at 15UTC)? Or does someone else want to organize/run the meeting?
DSpace 6.2 Immediate Release to fix Hibernate issues:
- Any other very obvious wins to "dspace-6_x" branch? https://github.com/DSpace/DSpace/pulls?utf8=%E2%9C%93&q=is%3Apr%20is%3Aopen%20base%3Adspace-6_x%20
- Discussion of DB Connections in DSpace 6 (Hibernate) vs DSpace 5. (More notes at DSpace Database Access)
- In DSpace 5, each "Context" established a new DB connection. Context then committed or aborted the connection after it was done (based on results of that request). Context could also be shared between methods if a single transaction needed to perform actions across multiple methods.
- In DSpace 6, Hibernate manages the DB connection pool. Each thread grabs a Connection from the pool. This means two Context objects could use the same Connection (if they are in the same thread). In other words, code can no longer assume each
new Context()is treated as a new database transaction.
- This is what we saw in DS-3659, two separate Context objects used the same connection, and one accidentally rolled back the changes of a previous Context (because they were in the same thread).
- Should we be making use of
SessionFactory.openSession()for READ-ONLY Contexts (or any change of Context state) to ensure we are creating a new Connection (and not simply modifying the state of an existing one)? Currently we always use
SessionFactory.getCurrentSession()in HibernateDBConnection, which doesn't guarantee a new connection: https://github.com/DSpace/DSpace/blob/dspace-6_x/dspace-api/src/main/java/org/dspace/core/HibernateDBConnection.java

Need Code Review, Flagged for ReleaseClick here to expand...
- DSpace + Spring: Slack Discussion on whether DSpace codebase should move more towards the Spring way of doing things (e.g. Dependency Injection via beans) or the traditional DSpace patterns (e.g. classloaders with little DI).
- This was asked on dspace-devel: https://groups.google.com/d/msg/dspace-devel/oBWibfQUXzI/y05K-wpLAgAJ
- DS-3372 and DS-3587: discussion required, should we add more SQL dialect support? MySQL, MS SQL? Are we ready to support, test and maintain these dialects in the future?
- Also asked on dspace-devel: https://groups.google.com/d/msg/dspace-devel/UfTU7AFZjs0/UOgiSnJKAgAJ
