  3. (Ongoing Topic) DSpace 6.x Status Updates for this week

    1. DSpace 6.3 Release Planning is ongoing. Big thanks to Terrence W Brady for working on so many PRs in the last week. We are still short on testers / reviewers. Remember, you need not be a committer to provide useful feedback, reviews and code contributions! The more people we have, the faster we can get through the outstanding work.

    2. Just a reminder to please keep the DSpace 6.3 Release Status Page updated as PRs are reviewed, merged, ported to master, etc. It's a big tricky page but quite useful as a central place to keep track of things. Soon we'll be able to rely more on JIRA and Github reports/filters, once we've got Fix Versions and milestones tagged in appropriately.
    3. Kim Shepherd will hang out in #dev for an hour or two after this meeting if anyone wants to help tag, test, review PRs and JIRA issues for 6.3
    4. Usual reminder: we could use your support!  See also the call for participation on all lists: https://groups.google.com/d/msg/dspace-tech/pBy714dGqU0/MGszGDCYAgAJ
  4. Tickets, Pull Requests or Email threads/discussions requiring more attention? (Please feel free to add any you wish to discuss under this topic)

    1. ORCID support broken:  
    2. DSpace 6 performance issues with items containing a lot of bitstreams? https://groups.google.com/forum/#!topic/dspace-tech/VIofW7EwEXY

Tabled Topics

These topics are ones we've touched on in the past and likely need to revisit (with other interested parties). If a topic below is of interest to you, say something and we'll promote it to an agenda topic!

  1. Management of database connections for DSpace going forward (7.0 and beyond). What behavior is ideal? Also see notes at DSpace Database Access
    1. 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.
    2. 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.
      1. 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
