As Bruno said. Try something like this: func uploadBig(url string ) error { file, err := os.Open("bigfile.txt") if err != nil { return err } defer file.Close() resp, err := http.Post(url, "text/plain", file) if err != nil { return err } defer

It’s not currently possible. Some of us run with patches exposing the TLS extensions to support this use case. The relevant GitHub issue is https://github.com/golang/go/issues/32936-eli On Mar 6, 2023, at 2:14 PM, Aurora wrote:Is it possible to capture the whole TLS handshake data coming from a

[go-nuts] [net/http] How to capture raw client TLS handshake data?

Is it possible to capture the whole TLS handshake data coming from a HTTP client request, enough to actually build a JA3 hash out of it? The tls.ClientHelloInfo does apparently give some but not all the parts which are needed to build a JA3 hash. -- You received this message because you are

Re: [go-nuts] cannot register generic function with template.Funcs

No, Go generics do not exist at runtime, so there is no way for this to possibly work in generality. The best you can do is make a function that takes an `any` or a `reflect.Value` and use `reflect` to type-check at runtime, returning an error if type-checking fails:

Re: [go-nuts] Best way to mark unused parameters/error values reported by linter

I would use the following if I truly wanted to ignore an error, but I would question if ignoring the error from os.Open was ever a good idea. If you want to handle a file not found error then do so, don't just ignore the error. file, _ := os.Open(name) //nolint: errcheck On Mon, 6 Mar 2023 at

You can easily get it to work, but not in a useful way I guess. https://go.dev/play/p/mq0O8OhJ1-a You could have a different template for each type you use I guess. -Bruno On Mon, Mar 6, 2023 at 4:43 PM Rory Campbell-Lange wrote: > Hi. I have a generic function > > func slicerG[A any](s

[go-nuts] cannot register generic function with template.Funcs

Hi. I have a generic function func slicerG[A any](s []A, i int) []A { fmt.Println(len(s), i) if i > len(s) { return s } return s[0:i] } When I try to register this in a template's FuncMap, it fails with "cannot use generic function slicerG

[go-nuts] Best way to mark unused parameters/error values reported by linter

Hello all, I'm incorporating golangci-lint linter aggregator in my codebase and facing a dilemma on how to mark false positives for these 2 linters: - errcheck - reports unchecked errors. - unparam - reports unused function parameters. The

Re: [go-nuts] HTTP client - streaming POST body?

The body is just an io.Reader. You just need to write one that materializes and streams the data you want instead of using a buffer with all of it. The entire design is to allow things like what you want to do. :) -Bruno On Mon, Mar 6, 2023 at 10:08 AM 'Jim Smart' via golang-nuts <

[go-nuts] HTTP client - streaming POST body?

Hi all, I'm looking for an HTTP client that allows my code to write the body content down the pipe while doing a POST. The use case here is that I'm wishing to send very large UPDATE/INSERT queries/commands to an HTTP endpoint, and the body content of those queries/commands is actually

Re: [go-nuts] Detecting / Avoiding network bottleneck when sending concurrent HTTP requests to many hosts.

Have you used netstat to check how many open connections you have? You probably need to forcibly close them so they don’t end up in time wait states. Also, you don’t say what N is? Lastly you will get different errors for a dns or host error than a resources exhausted. If you configure the

[go-nuts] Detecting / Avoiding network bottleneck when sending concurrent HTTP requests to many hosts.

Hi! I'm building a tool that needs to concurrently send request to multiple hosts (for fingerprinting purposes). I'm using github.com/valyala/fasthttp for the client but it works the same with net/http. The main program basically starts n workers and those will take endpoints to scan from a
