Agenda
Release 1.5.1, 1.3.3 and 1.26 all out this past week. w00t!
What’s up with the automated tests?
Recent/Current issues:
2 BBS Tests in the Interop Tests - disabled in a PR that has been merged.
But these tests are passing locally.
Seems to be with DIF Presentation Exchange
Approach is to leave for someone interested in getting BBS working. Issue 4073 for that.
6 Failing tests in the Postgres Tests in a dependabot PR – likely the PR actually breaks the test. Yay!
Investigate the library that is being updated.
Decision – merge or not.
Redis Cluster Plugin integrated test failing as well – Patrick is working this.
Regards the “works locally” issue – how do we test using the GH Runners?:
Put in a “Manual Tests” workflow that we can update as needed to manually trigger isolated tests.
Make as easy as possible – e.g have a variable that we list the tags of the tests to run and then run the other workflows.
Transition to the Credo Mediator at BC Gov. – Jamie Hale
Why the change? Answer – align the mediator stack with the Wallet so same team could manage it.
Not because the ACA-Py version wouldn’t work or was flawed – both needed work, BC chose to do that work in the Credo version.
How it was done
Updates to Credo to add support needed for scaling both the message handling layer (including websockets from a single Wallet moving between pods) and pickup protocol updates.
Two databases – the Askar database with keys and connections, a message queue management.
Both done in Postgres, so fewer dependencies, but the latter could have been done in Redis.
Postgres queuing support greatly improved recently, so performance loss not big – and one less dependency.
Script to update in place the Askar database. No loss of connections that already existed.
Migration: Backup, shutdown ACA-Py Mediator, run update script, startup Credo Mediator.
If problems – stop Credo Mediator, restore from backup, startup ACA-Py Mediator
Could ACA-Py be improved to support same features
Definitely. Some guidance was provided. Same architecture could be used, improve pickup (although pickup behaviour was already improved from start of work). Remaining work is getting the scaling right – which was most of the work needed in the Credo Mediator as well.
Review of PRs, recently closed PRs and Issues:
What’s next? Ideas…
Some work has been done on removing Indy logic/dependencies from the core and into a plugin. This is probably the most important change to be made, as it would greatly simplify the ACA-Py core and the building of additional plugins.
