  1. (Ongoing Topic) DSpace 7 Status Updates for this week (no major updates - other than Sprint going on)

    1. DSpace 7 Working Group (2016-2023) 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. (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. The ORCID (DS-3447) work has been merged, which is great news and removes the last blocker for release.

    2. As noted previously, the target release date is May 21, there are just a few PRs sitting with a 6.3 milestone, and we'd love help testing current 6.x branch, focusing on:

      1. Discovery (Solr) searches, including browsing, pagination, filters, special characters and very long requests
      2. General test of OAI-PMH (both ways)
      3. General test of REST API (aka Legacy REST) and REST Reports
      4. Flyway upgrades, fresh installs, database migrations
      5. ORCID authority control
      6. Subscriptions (with the sub-daily script)
      7. Statistics GeoIP (location) lookups and display
      8. CSV metadata exporting
      9. General performance (and particularly: XMLUI + items with many bitstreams)
      10. MathJAX rendering
  3. Tickets, Pull Requests or Email threads/discussions requiring more attention? (Please feel free to add any you wish to discuss under this topic)

    1. JIRA tickets / PRs marked for 6.3: https://github.com/DSpace/DSpace/pulls?q=is%3Aopen+is%3Apr+milestone%3A6.3

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
