suave | suave : structural variant explorer | Video Game library

This is just a guess, but I'm now able to reproduce this using PowerShell Invoke-WebRequest across multiple terminals. Each new terminal I open causes the number of open connections to increase. It turns out that Invoke-WebRequest uses a Keep-Alive header by default, so I was able to fix the problem by disabling this feature.

Thus, I'm wondering if perhaps your client (the thing sending the ping) is using a keep-alive header, but failing to reuse the connections it opens. If so, you could fix this by disabling keep-alive in the client.

I think you're looking for the basic response function:

JSON and form data (application/x-www-form-urlencoded, to be specific) have different syntax. Form data looks like key1=value1&key2=value2, so Suave is breaking the string on & and = in order to parse it.

You can parse JSON using mapJson instead. Something like this should work:

That's because you're using let!.

let! creates a breaking point in the async computation, splitting the code in two, with second part passed as a continuation (see this answer for how that works).

You can't return the whole thing as a single expression, because it's not, in fact, a single expression, it only looks like one. In reality, your function ends after let! and a totally separate function begins.

Here's a simplified version of your problem:

This looks like an FSharp.Core mismatch issue. Are you depending on a specific FSharp.Core package that is less than 4.7.2?

In general, unless you are writing a library intended for distribution on NuGet, you should not pin your dependency on FSharp.Core at all. For applications, always use whatever the .NET SDK provides and you'll virtually never run into these issues.

Explicitly FSharp.Core package references are an additional issue for library authors who need to worry about which F# versions their package is compatible with. If that is not a requirement for you, then it's best to never opt into that additional bit of complexity.

Using your sample code in a brand-new .NET 5 console app works for me:

Test.fsproj

Generally speaking, if you have any issue with the Cuba C library, the best thing to do is to contact the author: https://wwwth.mpp.mpg.de/members/hahn/. If an issue is fixed upstream, it'll be eventually included in the Cuba.jl Julia wrapper.

Understand that your memory allocation worry is misplaced for a few different reasons:

1. you aren't doing the benchmark correctly: the BenchmarkTools.jl package provides more accurate and reliable tools for benchmarking:

Does this solve your question?
TOTAL TIME: 1 to 2 seconds

Here I'm using the JSON library to do the computation as it is written in C(DONT GET CONFUSED WITH JSON'S FULL FORM) so its computationally efficient and fast.

I've just tested it & it seems to works just fine.

The only 2 issues seem to be that:

1. You don't use team anywhere (apart from a console.log statement).
2. At the moment when you console.log(team); the constant team will (yet) be null for the first time (because it still keeps the initial state).

Here's what I see in React dev tools after picking a random team in the :

You are using entity framework or some other orm. Which tries to translate your query into some sql syntax.

And i can see that you are trying to make an equetion p.Cor.Tom == t in this line. So Tom is a complex type. And you cant compare complex types in IQueryable queries. Because simply it doesn't know how to compare your custom class.

Basically what you can do is try to compare the primary or unique id of your classes. Like:
