Goal Upgrade a lightweight OTP application in a production cluster while keeping all nodes online. Constraints Stateful gen_server modules must survive the code change, dependencies must be pinned to avoid mismatched BEAM images, and the upgrade path must be reproducible. Unresolved Decision OTP’s release_handler offers a standard --upgrade workflow but its
Goal Determine whether release_handler:rollback/1 can safely return a running Erlang node to the previous release after an upgrade fails partway through activation. Constraints and uncertainty Assuming a standard OTP release with release_handler and relup support, the upgrade may already have loaded new modules and migrated some processes while other nodes o
Target-Specific Standard Library Access Gleam 1.0 provides distinct compiler targets for Erlang and JavaScript. While the core language is stable, the standard library contains modules specifically gated to a single runtime, such as gleam/erlang/process for the BEAM and gleam/javascript for JS environments. Cross-Target Library Constraints When developing a
