To avoid problems frequently associated with subclassing, and the possible
versioning ergonomics of subclassing the wrong version, this changes the
plugin infrastructure to no longer require subclassing the abstract class.
This was causing the `checkOperationPlugin` to be added to the list of
plugins to be executed, thus resulting in an additional plugin pass (of the
same plugin) for each request.
1st request = 1 plugin
2nd request = 2 of the same plugin
3rd request = 3 of the same plugin
Obviously, this was not intended.
This mostly reverts fd34771841 along with a
number of slight adjustments to avoid other typing luxuries which were
introduced with TypeScript 3.x.
While the generic `ServerOptionFunction` types and `HandlerArguments`
generic rest argument type were certainly welcome additions to the codebase,
they present a backwards compatibility problem for consumers of Apollo
Server who have not yet made the jump to TypeScript 3.x.
With any luck, when we bump the major version of Apollo Server to 3.x, and
in accordance with semantic versioning, we'll be in the position to
straight-up revert this commit.
This commit supports two new concepts for reporting:
1. Client identity
2. Schema awareness
Client identity allows the GraphQLRequestContext to be mapped into
`clientId`, `clientName`, and `clientVersion` which can be used to
filter and view requests and metrics by client information.
Schema awareness introduces schema branches which allow arbitrary
strings to generate new "branches" (or variants) of a schema.
This commit adds a new field to the GraphQLServiceContext which is
a hashed representation of the schema. This is useful as a key value
to represent the schema and is sent as part of reporting to engine
when enabled
Prior to embarking on the request pipeline work, and to facilitate
development on the new request pipeline, @martijnwalraven and myself
intentionally reverted some commits that had been recently introduced but
conflicted with the request pipeline branch that was already in-flight.
Rather than dealing with an incredibly difficult merge conflict, it was
easier to revert them an re-apply them later.
Original commits, reversions, and reintroductions:
* 6d6c9ff, 03a894d, b90ccc2
* 96af44e, 68c82e6, 81c4642
* 408198e, 2b470e1, 84bc834
* 4175f1b, 38e7b6a, 261994c
As is demonstrated by this short follow-up commit, this was all that was
necessary to make it work in the new model - once that model was finished.
While we're certain that the new request pipeline and its plugin model will
actually better support some of the behavior that required these initial
commits in the name of not introducing breaking changes, we feel it's
necessary to maintain their support.
I will point out, if you are at all affected by the above commits, we may
consider deprecating portions of those APIs in the not too distant future,
but we hope that the new model will help support those needs even better.
* Pass the context along to all the extension methods
Addresses #1343
With this change you should now be able to implement an extension like so:
```javascript
class MyErrorTrackingExtension extends GraphQLExtension {
willSendResponse(o) {
const { context, graphqlResponse } = o
context.trackErrors(graphqlResponse.errors)
return o
}
}
```
Edit by @evans :
fixes#1343fixes#614 as the request object can be taken from context or from requestDidStart
fixes#631 ""
* Remove context from extra extension functions
The context shouldn't be necessary for format, parse, validation, and
execute. Format generally outputs the state of the extension. Parse and
validate don't depend on the context. Execution includes the context
argument as contextValue
* Move change entry under vNext
