Minutes

  1. Yinlin: Just got word we have funding from Amazon for using AWS for performance testing
    1. Will have funding transferred to his account, and will announce to the tech list
    2. Funding is good for 1 year
    3. See https://docs.google.com/document/d/1jYd5jQpU_cZ4fXQOkWny2M42QYHFqoL2EqRjVcvEv1k/edit?usp=sharing
  2. Release testing of 4.7.4
    1. RC 2 removes one commit from the previous RC (related to consolidating configuration that would not be backwards compatibility if people were using custom config)
    2. Release pushed out to Aug 7th
    3. Jennifer Smith is working on test Sufia and CC, but running to dependency problems
      1. Esme: I can test Sufia and CC if she can't resolve those
    4. Carrick: I've tested Valkyrie, Hyrax and Avalon locally
      1. Exploring performance testing, to be able to compare performance testing across releases
      2. Will be able to test migrating small repository from 4.7.2 and 4.7.1
      3. We have a Docker-ize version of Avalon with Fedora 4.7.4-RC-2, willing to share with anyone who's interested in spinning it up
      4. See also: https://github.com/seanlw/avalon-vagrant
    5. Danny L.: Have done basic CLAW testing, will update the release testing page
    6. Database testing: Danny B. will test MySQL, and Jared will test PostgreSQL
    7. Windows testing: Aaron Birkland has done this in the past, Andrew will reach out to him
  3. Import/Export release
    1. There is a new 0.2 release of the import/export utility with lossless roundtripping (including system timestamps), version export (no import yet), changing the repository baseURL, exporting based on inbound relationships.
    2. Will send out the announcement today
    3. Importing versions wasn't ready, so it will go in a 0.3 release when it's ready
      1. Significant change in the way that import works, since it changes to a timestamp-based order
    4. Princeton is using the Import/Export utility (waiting on more storage for full deployment)
      1. Others are clearly interested, including Univ. Cincinnati, Northwestern, etc.
    5. Verification tool has a few outstanding issues, but very close to ready to release
  4. API alignment sprints
    1. Several people signed up to work on upcoming sprints
    2. Fedora 4.7.4 - Specification Delta Document: a place to collect notes about difference between the API spec and the Modeshape implementation
    3. That document will be very helpful for the API alignment sprints — please help fill it out
  5. Message to fedora-tech from Peter Eichman:
    1. Peter: Doing bulk processing and it would work for a while but eventually hang, seeing memory usage creep up and hit max
      1. Turning off messaging didn't fix the problem (when Solr indexing turned back on, it didn't show the same pattern)
      2. Turning off transactions didn't fix the problem either
    2. Esme: We've seen the same issue at Princeton, and haven't found any solution (increasing memory allocation and restarting Fedora help somewhat)
    3. Andrew: Others have worked on this too — helping pinpoint where this is happening would be very helpful
    4. Peter: We'll try profiling and report back
  6. Reverting CND changes
    1. Esme: I can review those
