build(deps): Bump oban from 2.18.0 to 2.19.4

[dependabot]

Bumps oban from 2.18.0 to 2.19.4.

Release notes

Sourced from oban's releases.

v2.19.2

Enhancements

• [Oban] Allow setting a MFA in :get_dynamic_repo

  Anonymous functions don't work with OTP releases, as anonymous functions cannot be used in configuration. Now a MFA tuple can be passed instead of a fun, and the scaling guide recommends a function instead.

• [Cron] Include configured timezone in cron job metadata

  Along with the cron expression, stored as cron_expr, the configured timezone is also recorded as cron_tz in cron job metadata.

• [Cron] Add next_at/2 and last_at/2 for cron time calculations

  This implements jumping functions for cron expressions. Rather than naively iterating through minutes, it uses the expression values to efficiently jump to the next or last cron run time.

• [Executor] Always convert queue_time to native time unit

  The telemetry docs state that measurements are recorded in native time units. However, that hasn't been the case for queue_time for a while now. It usually worked anyway native and nanosecond is of the same resolution, but now it is guaranteed.

Bug Fixes

• [Peer] Correct leadership elections for the Dolphin engine

  MySQL always returns the number of entries attempted, even when nothing was added. The previous match caused all nodes to believe they were the leader. This uses a secondary query within the same transaction to detect if the current instance is the leader.

• [Reindexer] Drop invalid indexes concurrently when reindexing.

  The DROP INDEX query would lock the whole table with an ACCESS EXCLUSIVE lock and could cause queries to fail unexpectedly.

• [Testing] Use Ecto.Type.cast/2 for backward compatibility

  The cast!/2 function wasn't added until Ecto 3.12. This reverts time casting to use cast/2 for compatibility with earlier Ecto versions.

• [Worker] Validate that the unique option isn't an empty list.

  An empty list was accepted at compile time, but wouldn't be valid later at runtime. Now the two validations match for greater parity.

v2.19.1

Bug Fixes

• [Mix] Improve igniter installer idempotency and compatibility.

  The installer now uses on_exists: :skip when generating a migration, so it composes safely with other igniter installers. It also removes unnecessary add_dep calls that would overwrite a previously specified Oban version with ~> 2.18.

v2.19

The minimum Elixir version is now v1.15. The official policy is to only support the three latest versions of Elixir.

🐬 MySQL Support

Oban officially supports MySQL with the new Dolphin engine. Oban supports modern (read "with full JSON support") MySQL [versions from 8.4][m84] on, and has been tested on the highly scalable [Plantescale][pla] database.

Changelog

Sourced from oban's changelog.

v2.19.4 — 2025-03-25

Bug Fixes

• [Validation] Partially revert removal of unused validators.

  Some validations are actively used by the current version of Oban Pro and shouldn't have been removed.

• [Plugins] Handle and log all unexpected messages.

  Some genservers handled unexpected messages while others did not. Now all plugins and other genservers consistently handle those messages. Public facing modules, such as plugins, all log a warning about the message while internal modules ignore them.

v2.19.3 — 2025-03-24

Bug Fixes

• [Install] Use configure_new for idempotent installation.

  Prevent overwriting existing :oban configuration when running installer.

• [Sonar] Correct stale node logic for sonar tracking.

  The original code had a logical error. By calculating stale as current time + interval * multiplier, it would reject nodes that were recorded in the future relative to the current time (which is unlikely to be the intended behavior) The new code correctly identifies stale nodes by checking if they're older than the threshold.

Enhancements

• [Worker] Check for worker functions rather than behaviour

  Behaviours can't contain overlapping callbacks. In order to have a worker-like module that defines it's own timeout/1 or backoff/1, we must use an alternate callback.

• [Worker] Improve warning message on incorrect return from perform/1.

• [Telemetry] Skip logging peer events unless node leadership changes.

  The default logger only outputs peer events when something changed: either the peer became leader or lost the leader.

• [Validation] Add schema validator for tuple options.

  Being able to validate tuples eliminates the need for custom validator functions in several locations.

• [Oban] Compatiblity updates for changes in the upcoming Elixir v1.19
