  • fastcgi_read_timeout is not proxy_read_timeout

    Note2 min read

    A long-running request returning 504 after exactly sixty seconds is nginx timing out, and which directive applies depends on how the request reaches PHP. Four numbers have to…

  • A meta box that still works, with the flag that says so

    Note2 min read

    Most meta boxes still render in the new editor through a compatibility layer, and the ones that break do so because they rely on the DOM around them…

    Three application servers each running the same crontab means every scheduled task runs three times, and the invoice job discovers this before you do. The lock is a…

  • Model events do not fire on a mass update

    An observer that keeps a search index in step works perfectly until somebody writes a query builder update, at which point the rows change and nothing notices. This…
