This is purely a hack so as to contextually control DEFAULT_AUTO_SELECT_DEPTH as the default value of 2 may not be sufficient when sending the request and merging the response into the Operation object.

Example schema:

type Query {
        ...
	findProducts(input: ProductSearchInput): ProductSearchResults!
       ...
}

type ProductSearchResults {
	results: [ProductSearchResult!]!
	more: Boolean!
	nextLimit: Int!
	nextOffset: Int!
}

type ProductSearchResult {
	product: Product!
	instances: [Instance]!
}

type Product {
	id: ID!
	internalName: String!
	displayName: String
	description: String
	license: String
	reference: Json
	dataSteward: Json
	tags: [Tag!]!
	releases: [Release]!
}

type Instance {
	id: ID!
	productId: ID!
	productName: String!
	effectiveDateRange: DateRange
	ignoreTimezone: Boolean
	tags: [Tag!]
	reference: Json
	extent: GeoJson
	assets: [Asset!]!
	parents: [Instance!]
}

And a basic consumption...

op = Operation
op.find_products(input=...).__fields__()

results = op + endpoint.query(op)

With the default depth of 2, Product.tags and Product.releases (amongst other fields) are not included in the merged results.

With this PR, I can safely do the following and get Product.tags and Product.releases in the results

with select_depth(3):
  op = Operation
  op.find_products(input=...).__fields__()
  
  results = op + endpoint.query(op)

Obviously, a cleaner approach would be lovely (e.g. Operation(Query, max_select_depth=10) but this is the dirty solution to achieve my needs

hi @dustymugs, why don't you simply pass the argument to the functions?

Other than that, I highly recommend to NOT use auto-selection since it goes against the GraphQL principles. It will bring you lots of data, it will make your code more subject to breakages and so on.

Note this is a pure "dev only" thing I added to help quick hacks... I regret adding it when I see some "misuses" :-P

@dustymugs did you get the chance to see the branch conflicts that must be resolved?
