2.0.4 Causes test failures, not sure why

juulSme commented 5 years ago

Our CI started to fail after updating db_connection to 2.04. It is not set as an explicit dependency, but is pulled in with (I think?) Phoenix / Ecto. Adding {:db_connection, "2.0.3"} to our mix.exs fixed the issue.

This is a project that has recently been upgraded from Elixir 1.6.2 and Phoenix 1.3.x to Elixir 1.8 and Phoenix 1.4, so perhaps there is some old config somewhere that causes the issue, but during a build there are no obvious deprecation warnings or stuff like that.

Environment

OS: Ubuntu 18.04 Docker: 18.09.1 build 4c52b90 Elixir 1.8 Phoenix 1.4.0 Ecto 3.0.6 Postgres 9.6

Our CI builds in-Docker with the Elixir 1.8-alpine image.
