CI run: https://github.com/coder/coder/actions/runs/21133032582
Commit: d176714f90f2c4dffa4c182722f6b16deface38a (Cian Johnston)
Job: test-go-pg (windows-2022)

What failed

Go test failures in the cli package:

TestUserList/SessionAuthErrorHasHelperText (and the parent TestUserList)

Key log excerpt:

Received unexpected error:
create database:
  - create db with template:
    github.com/coder/coder/v2/coderd/database/dbtestutil.createDatabaseFromTemplate
        coderd/database/dbtestutil/postgres.go:204
  - read tcp 127.0.0.1:50677->127.0.0.1:5432: wsarecv: The I/O operation has been aborted because of either a thread exit or an application request.

Initial assessment

This looks like an infrastructure / embedded-postgres stability issue on Windows during test database creation (connection abruptly aborted). It may be intermittent and environment-dependent.

Files implicated by stack trace:

coderd/database/dbtestutil/broker.go
coderd/database/dbtestutil/postgres.go (createDatabaseFromTemplate)
cli/userlist_test.go

Ownership / assignment rationale

Recent substantive work in coderd/database/dbtestutil/postgres.go and related dbtestutil plumbing was done by Spike Curtis (e.g. commits 596fdcba817e, e2076beb9f7a).

There is also an issue reading and writing to the pseudoconsole in a different test:

These seem like very fundamental Windows, or at least Go-on-Windows errors. If reading and writing to TCP sockets or pseudoconsoles starts failing then we really are in a bad way.

I'm going to close this one, but if we see it again we might need to start digging really deep.
