For misspelled enums or field names, these suggestions can be helpful.
This also changes the suggestions algorithm to better detect case-sensitivity mistakes, which are common
ref: graphql/graphql-js#1153
This generalizes the "arguments of correct type" and "default values of correct type" to a single rule "values of correct type" which has been re-written to rely on a traversal rather than the utility function `isValidLiteralValue`. To reduce breaking scope, this does not remove that utility even though it's no longer used directly within the library. Since the default values rule included another validation rule that rule was renamed to a more apt "variable default value allowed".
This also includes the original errors from custom scalars in the validation error output, solving the remainder of graphql/graphql-js#821.
ref: graphql/graphql-js#1144
This includes:
graphql/graphql-js#1147graphql/graphql-js#355
This also fixes two bugs in the Schema
- types that were not found where still added to the typeMap
- InputObject args should not be searched for types.
This is a fairly major refactoring of coerceValue which returns an Either so it can return a complete collection of errors. This allows originalError to be preserved for scalar coercion errors and ensures *all* errors are represented in the response.
This had a minor change to the logic in execute / subscribe to allow for buildExecutionContext to abrupt complete with multiple errors.
ref: graphql/graphql-js#1133
If a GraphQLError represents multiple nodes across files (could happen for validation across multiple parsed files) then the reported locations and printError output can be incorrect for the second node. This ensures locations are derived from nodes whenever possible to get correct location and amends comment documentation.
ref: graphql/graphql-js#1131
This moves validation out of GraphQLSchema's constructor (but not yet from other type constructors), which is responsible for root type validation and interface implementation checking.
Reduces time to construct GraphQLSchema significantly, shifting the time to validation.
This also allows for much looser rules within the schema builders, which implicitly validate while trying to adhere to flow types. Instead we use any casts to loosen the rules to defer that to validation where errors can be richer.
This also loosens the rule that a schema can only be constructed if it has a query type, moving that to validation as well. That makes flow typing slightly less nice, but allows for incremental schema building which is valuable
ref: graphql/graphql-js#1124
Lifted from / inspired by a similar change in graphql/graphql-js#722, this creates a new function `printError()` (and uses it as the implementation for `GraphQLError#toString()`) which prints location information in the context of an error.
This is moved from the syntax error where it used to be hard-coded, so it may now be used to format validation errors, value coercion errors, or any other error which may be associated with a location.
ref: graphql/graphql-js
BREAKING CHANGE: The SyntaxError message does not contain the codeframe anymore and only the message, (string) $error will print the codeframe.
This factors out the enum value validation from scalar value validation and ensures the same try/catch is used in isValidLiteralValue as isValidPHPValue and protecting from errors in valueFromAST.
ref: graphql/graphql-js#1126
A common case is encountering an error which blames to a single AST node. Ensure the GraphQLError constructor can handle this case.
ref: graphql/graphql-js#1123
This adds a new function `getIntrospectionQuery()` which allows for some minor configuration over the resulting query text: to exclude descriptions if your use case does not require them.
ref: graphql/graphql-js#1113
`OverlappingFieldsCanBeMerged` would infinite loop when passed something like
```graphql
fragment A on User {
name
...A
}
```
It's not `OverlappingFieldsCanBeMerged`'s responsibility to detect that validation error, but we still would ideally avoid infinite looping.
This detects that case, and pretends that the infinite spread wasn't there for the purposes of this validation step.
Also, by memoizing and checking for self-references this removes duplicate reports.
ref: graphql/graphql-js#1111
This improves the overlapping fields validation performance and improves error reporting quality by separating the concepts of checking fields "within" a single collection of fields from checking fields "between" two different collections of fields. This ensures for deeply overlapping fields that nested fields are not checked against each other repeatedly. Extending this concept further, fragment spreads are no longer expanded inline before looking for conflicts, instead the fields within a fragment are compared to the fields with the selection set which contained the referencing fragment spread.
e.g.
```graphql
{
same: a
same: b
...X
}
fragment X on T {
same: c
same: d
}
```
In the above example, the initial query body is checked "within" so `a` is compared to `b`. Also, the fragment `X` is checked "within" so `c` is compared to `d`. Because of the fragment spread, the query body and fragment `X` are checked "between" so that `a` and `b` are each compared to `c` and `d`. In this trivial example, no fewer checks are performed, but in the case where fragments are referenced multiple times, this reduces the overall number of checks (regardless of memoization).
**BREAKING**: This can change the order of fields reported when a conflict arises when fragment spreads are involved. If you are checking the precise output of errors (e.g. for unit tests), you may find existing errors change from `"a" and "c" are different fields` to `"c" and "a" are different fields`.
From a perf point of view, this is fairly minor as the memoization "PairSet" was already keeping these repeated checks from consuming time, however this will reduce the number of memoized hits because of the algorithm improvement.
From an error reporting point of view, this reports nearest-common-ancestor issues when found in a fragment that comes later in the validation process. I've added a test which fails with the existing impl and now passes, as well as changed a comment.
This also fixes an error where validation issues could be missed because of an over-eager memoization. I've also modified the `PairSet` to be aware of both forms of memoization, also represented by a previously failing test.

This changes the parsing grammar and validation rules to more correctly implement the current state of the GraphQL SDL proposal (facebook/graphql#90)

BREAKING CHANGE: SchemaBuilder::build() and buildAST() and constructor
removed the typedecorator, as not needed anymore as library can now resolve
union and interfaces from generated schemas.
* Generalizes building a value from an AST, since "scalar" could be misleading, and supporting variable values within custom scalar literals can be valuable.
* Replaces isNullish with isInvalid since `null` is a meaningful value as a result of literal parsing.
* Provide reasonable default version of 'parseLiteral'
