Tickets created this week:
Minutes
- Yinlin: Just got word we have funding from Amazon for using AWS for performance testing
- Will have funding transferred to his account, and will announce to the tech list
- Funding is good for 1 year
- See https://docs.google.com/document/d/1jYd5jQpU_cZ4fXQOkWny2M42QYHFqoL2EqRjVcvEv1k/edit?usp=sharing
- Release testing of 4.7.4
- 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)
- Release pushed out to Aug 7th
- Jennifer Smith is working on test Sufia and CC, but running to dependency problems
- Esme: I can test Sufia and CC if she can't resolve those
- Carrick: I've tested Valkyrie, Hyrax and Avalon locally
- Exploring performance testing, to be able to compare performance testing across releases
- Will be able to test migrating small repository from 4.7.2 and 4.7.1
- 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
- See also: https://github.com/seanlw/avalon-vagrant
- Danny L.: Have done basic CLAW testing, will update the release testing page
- Database testing: Danny B. will test MySQL, and Jared will test PostgreSQL
- Windows testing: Aaron Birkland has done this in the past, Andrew will reach out to him
- Import/Export release
- 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.
- Will send out the announcement today
- Importing versions wasn't ready, so it will go in a 0.3 release when it's ready
- Significant change in the way that import works, since it changes to a timestamp-based order
- Princeton is using the Import/Export utility (waiting on more storage for full deployment)
- Others are clearly interested, including Univ. Cincinnati, Northwestern, etc.
- Verification tool has a few outstanding issues, but very close to ready to release
- API alignment sprints
- Several people signed up to work on upcoming sprints
- Fedora 4.7.4 - Specification Delta Document: a place to collect notes about difference between the API spec and the Modeshape implementation
- That document will be very helpful for the API alignment sprints — please help fill it out
- Message to fedora-tech from Peter Eichman:
- Peter: Doing bulk processing and it would work for a while but eventually hang, seeing memory usage creep up and hit max
- Turning off messaging didn't fix the problem (when Solr indexing turned back on, it didn't show the same pattern)
- Turning off transactions didn't fix the problem either
- Esme: We've seen the same issue at Princeton, and haven't found any solution (increasing memory allocation and restarting Fedora help somewhat)
- Andrew: Others have worked on this too — helping pinpoint where this is happening would be very helpful
- Peter: We'll try profiling and report back
- Peter: Doing bulk processing and it would work for a while but eventually hang, seeing memory usage creep up and hit max
- Reverting CND changes
- Esme: I can review those
