Description

From the spec: https://jmap.io/spec-core.html#changes

The Foo/changes method allows a client to efficiently update the state of its Foo cache to match the new state on the server. 

How

Serializer to deserialize/serialize Email/changes request/response has already been written with Mailbox/changes implementation. We now only need to implement Email/changes method + tests.

Example

Request

[[ "Email/changes", {
 "accountId": "29883977c13473ae7cb7678ef767cbfbaffc8a44a6e463d971d23a65c1dc4af6",
 "sinceState": "000001"
}, "t0" ]]

 

Response

[[ "Email/changes", {
 "accountId": "29883977c13473ae7cb7678ef767cbfbaffc8a44a6e463d971d23a65c1dc4af6",
 "oldState": "000001",
 "newState": "000002",
 "hasMoreChanges": false,
 "created": [ "1", "2" ],
 "updated": [],
 "destroyed": []
}, "t0" ]]

DoD

Write integration tests to show that we can retrieve the changes to email(s) from a particular state.
