Discrepance between an array response from graphQL and same array printed with a console log
0 I have a very strange behaviour and I need your help. I retrieve a list of content from a GraphQl API that i attach you: client.query({query: PAGES_LIST}).then(res => console.log(res.data.pages) The problem is that the response from the network is that: [ { "id": "ddf", "title": "DDF", "type": "HOME", "draft": false, "newtonId": "64edfc8f3508bb20a9dbef19", "creationDate": "2023-08-29…

GCC removes a bounds check in the right operand of &&, but not in the left operand, why?
18 I have the following C/C++ code snippet: #define ARRAY_LENGTH 666 int g_sum = 0; extern int *g_ptrArray[ ARRAY_LENGTH ]; void test() { unsigned int idx = 0; // either enable or disable the check "idx < ARRAY_LENGTH" in the while loop while( g_ptrArray[ idx ] != nullptr /* && idx < ARRAY_LENGTH */ )…

GraphQL uses REST query which has an array as JSON response does not work
0 I’m trying to query another system with a GraphQL query. Due to the system only takes REST queries I use the @rest operator to convert the query. But the REST query has an array as response which leads to the following error: {"name":"ApolloError","graphQLErrors":[],"clientErrors":[],"networkError":{},"message":"typename is undefined"} GraphQL query: const QueueStatusQuery = gql` query checkQueueStatus_HLS{ robot(input:{})…

Execute a graphql query using painless script, with params having hyphen and space and match a field property with type keyword and text
0 I’m new to graphql and opensearch queries. Here I’m trying to add a filter to existing query for city, my params inside the query are having data with – and spaces. While I’m trying to query it, data is getting filtered only with first word. For example, my params is having an array "cityNames"…

Convenient way to declare 2D (or even higher dimension) arrays with std::array
26 I’m about to convert a lot of old C++ code to more modern C++. There are many raw 2D arrays in that code like: Foo bar[XSIZE][YSIZE]; And I’m about to replace these declarations with std::array<std::array<Foo, YSIZE>, XSIZE> bar; This is a convenient way because the statements stay the same and the code is supposed…

In C++ Inheritance, Derived class destructor not called when pointer object to base class is pointed to array of derived class
17 I have an Animal class with constructor and destructor. Cat have a private Brain* attribute. Upon construction, Cat creates his Brain using new Brain(); Upon destruction, Cat deletes his Brain. I don’t understand why The cat’s and brain’s destructors not called, when my Base class destructor is virtual? #include <iostream> using std::cout ; using…

Is gcc wrong to allow the initialization of a const array member with another array reference?
8 While (re)implementing a simple constexpr map, I wrote this (godbolt): template <class key_type, class value_type, int N> class flat_map { private: struct pair { key_type key; value_type value; }; const pair elements[N]; public: consteval flat_map(const pair (&arr)[N]) noexcept : elements(arr) // works on gcc?! {} [[nodiscard]] consteval value_type operator[](const key_type key) const { for…

Why is b.pop(0) over 200 times slower than del b[0] for bytearray?
24 Letting them compete three times (a million pops/dels each time): from timeit import timeit for _ in range(3): t1 = timeit(‘b.pop(0)’, ‘b = bytearray(1000000)’) t2 = timeit(‘del b[0]’, ‘b = bytearray(1000000)’) print(t1 / t2) Time ratios (Try it online!): 274.6037053753368 219.38099365582403 252.08691226683823 Why is pop that much slower at doing the same thing? python…
