  • Designing an API two mobile clients can live with

    Deep dive14 min read

    Two apps, two release cycles, and neither can be forced to update. What is additive, what is not, and the decisions that have to be made before the…

  • withoutOverlapping on a scheduled command

    Note1 min read

    A scheduled task that occasionally runs longer than its interval will be started again while the first is still going, which for an import means two processes writing…

  • Laravel 5.4 dropped the model events you were using

    Note2 min read

    5.4 removed the string-based model events fired through the event dispatcher — eloquent.saved: AppOrder and its relatives — in favour of an $dispatchesEvents map to real classes. The…

  • Schema changes that do not need a maintenance window

    Deep dive9 min read

    An ALTER on a 40 million row table held a metadata lock behind every query. Expand, migrate, contract turns one blocking release into three safe ones.

  • Read replicas, and the queries that must not use them

    Deep dive8 min read

    Reads moved to a replica and checkout started showing empty carts. Read-after-write, sticky connections, and measuring the lag rather than assuming it.

  • Assert against the database, not against the response

    Note2 min read

    A feature test asserting a 302 and a flash message proves the controller ran. It does not prove the order was created, and it passes just as happily…

  • Blade components before they were components

    Note1 min read

    @include passes variables and shares the parent scope, which means a partial silently depends on whatever happened to be defined where it was included. @component takes a slot…
