Conditional Put: Three Approaches Compared

1. Our Approach (Serializable Snapshot Isolation)

Repo.transaction(
  fn ->
    if has_events_since?(filters, max_position) do
      Repo.rollback(:inconsistent)
    else

Ring handler a function which accepts a request (map) and returns a response (map).

Ring middleware

function (handler, &args -> function(request -> response) because it is a closure handler and &args are in scope within the returned handler function.

a function which accepts a "next handler" (the next handler in the chain) + any extra arguments and returns a handler (function), which will accept a request and return a response.

if(document.queryCommandSupported('copy')) {
        if(text=='') { text = ' '; } // empty inputs do not get selected

        // copy text to off-screen input
        $('#clipboard').val(text);

        // 1.) does copy empty inputs, but adds newline before content
        var range = document.createRange();
 range.selectNode(document.querySelector('#clipboard'));

Proposal to allow adapters to be switched at runtime in tests.

Example:

We have an EntityStore which has functions to save and find entities.

In our tests we want the ability to use different implimentations (real, dummy, in-memory etc.) in different tests.

We might want to use the real adapter in acceptance tests, a dummy one just to assert the adapter is called, and an in-memory adapter for all other tests (because it's faster).

When an interger is sent for monitor>type an internal error occurs. If a string is sent as in the main.yml example it is okay.

When an internal error occurs a 200 response not 500 is sent.

When an error occurs (e.g. monitor already exists) a 200 response is sent.
