Migrate Hot Chocolate Fusion from 16.6 to 16.7

Update every Hot Chocolate Fusion package in the application to version 16.7 before applying these changes.

Deprecations#

Raw condition masks replaced by ConditionFlags#

Fusion can now compile and execute operations with more than 64 distinct @skip/@include conditions or @defer conditions. MaxAllowedIncludeConditions limits the combined @skip and @include conditions, and MaxAllowedDeferConditions limits the @defer conditions. Both limits default to 1,024. An operation that exceeds either limit produces a GraphQL request error during operation compilation.

Configure the limits through FusionRequestOptions on the gateway:

builder.Services
    .AddGraphQLGatewayServer()
    .ModifyRequestOptions(options =>
    {
        options.MaxAllowedIncludeConditions = 2_048;
        options.MaxAllowedDeferConditions = 2_048;
    });

ConditionFlags contains the first 64 evaluated conditions and any remaining conditions. Pass the condition carriers from OperationPlanContext to the Fusion Selection overloads:

- bool included = selection.IsIncluded(context.IncludeFlags);
- bool deferred = selection.IsDeferred(context.DeferFlags);
+ bool included = selection.IsIncluded(context.IncludeConditionFlags);
+ bool deferred = selection.IsDeferred(context.DeferConditionFlags);

Replace every deprecated Fusion Selection overload as follows:

The deprecated raw overloads continue to work for operations with at most 64 conditions. When an operation has more than 64 conditions of the corresponding kind, the deprecated raw inclusion overloads throw InvalidOperationException for every conditional selection and the deprecated raw defer overloads throw for every deferrable selection, including selections whose own conditions are all among the first 64; raw inclusion evaluation does not throw for an unconditional selection, and raw defer evaluation does not throw for a non-deferrable selection. Releases before 16.7 rejected operations with more than 64 conditions during compilation.
