The express-graphql reference implementation [provides a check]
(2e27a73358/src/index.js (L201-L208))
to protect against cases where a GET request is made that does not
have a `query` parameter where the GraphQL query would be present.
Without this guard, graphql-js's `parse` will return `undefined`
for the `DocumentNode` since it has no document to read. Subsequently
passing this to `isQueryOperation` results in a `TypeError`, because
we are providing `undefined` where `getOperationAst` [expects to get
a DocumentNode](5fe39262a3/src/utilities/getOperationAST.js (L19)).
A new test file is added for `runHttpQuery`, as one previously did
not seem to exist.
This change was introduced by the changes in apollographql/apollo-server#802
but first showed its head in apollographql/apollo-server#908. The reason that
violations in new type definitions aren't being found until subsequent PRs
isn't entirely clear but, ignoring that CI-related annoyance, the problem
itself here is very concrete.
It traces back to a major version update to `@types/mocha` via [Exhibit A],
which makes it unacceptable to return anything besides a `Promise` or
_nothing_ from a Mocha test factory.
I agree with this change in principle, since generally speaking there can be
multiple `expect` statements in each test and there is no particular reason
that the last one's value should be getting returned as Mocha doesn't do
anything functional with it.
More than anything, this seems like an artifact of an ESLint rule which
mandated that the last value in a function be returned, à la CoffeeScript or
other languages.
This will fix the failing tests on apollographql/apollo-server#908 and other
PRs currently in-flight.

There were many missing releases and bullet points as well as inaccurate
ones. For example, it was impossible to figure out that users of Hapi 16 who
want to use Apollo Cache Control needed to use precisely version 1.2.0 of
apollo-server-hapi (which wasn't even mentioned).
Link to CHANGELOG from all READMEs. Add READMEs for the graphql-server-*
packages. Add an explanation of our versioning system to the top of
CHANGELOG.md.
This fixes executing a query if all fields it encounters have synchronous resolvers, for which behavior changed in 0.12.x due to graphql/graphql-js#1115.

This fixes the default behavior for class-based contexts by also cloning the prototype, and it allows you to customize per-operation behavior by passing in a function as context.
