  1. DSpace 7 Community Sprints : Reminder that the first spring is coming up on May 7-18.  Signup if interested
    1. Sprint goals documented at DSpace 7 Community Sprint 1
  2. (Ongoing Topic) DSpace 7 Status Updates for this week (no major updates - other than Sprint reminder)

    1. DSpace 7 Working Group is currently concentrating on building out search, submission, authentication and MyDSpace functionality. 4Science submission/workflow UI (see  video, slides) to be submitted as series of PRs in coming weeks.
    2. DSpace 7 Dev Status spreadsheet: https://docs.google.com/spreadsheets/d/18brPF7cZy_UKyj97Ta44UJg5Z8OwJGi7PLoPJVz-g3g/edit#gid=0
  3. (Ongoing Topic) DSpace 6.x Status Updates for this week

    1. DSpace 6.3 Release Planning is ongoing. Thanks to those who have been helping out with tests and reviews over the last week.

    2. Over the next week or two, more open PRs will be shifted to 6.4 as we don't have enough resource to get through them all. DS-3447 has also given us a bit more work to do, to get some important bug fixes into the release (ORCID API functionality). The schedule will therefore be pushed out a bit, perhaps a 'soft freeze' by May 14 or 15 and release by May 21. If we can get to a 'soft freeze' on 6.x merges, we can start testing a 6.3 release more thoroughly. More info at: https://groups.google.com/forum/#!topic/dspace-devel/RbHhnhaFOto

  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:   DS-3447 - Getting issue details... STATUS
    2. DS-3649 - Getting issue details... STATUS
    3. Quick win PRs for 6.3 or 7.0 needing a +1 in Github

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
