[go-nuts] Re: HTTPS proxy issue using CONNECT method

Hi Mauro, In your curl examples the CONNECT method was used in both cases because you forced it to with the --proxytunnel option. If you run those same commands without that option then you will find that curl will operate the same as Go and will only use the CONNECT method when the target is H

Hi folks, Thanks for all the inputs, I really appreciate the effort and help :-) Regardless of the whole discussion of whether or not tuples are a good or bad data structure, they exist out there in the wild, and we have to deal with them in many situations - of course, in our own code we can o

Re: [go-nuts] Golang 1.19+ preemption model on a preemptive linux kernel?

I don’t think the analysis by alphadose in the issue you cite is correct. Go added async pre-emption (via signals) and I believe it can preempt a Go thread anywhere but in an internal critical section. Ian would know for sure. It is certainly not only at a function call boundary because that wou

[go-nuts] Re: HTTPS proxy issue using CONNECT method

Hello Graham, Would not make more sense to deal with both cases HTTPS and HTTP in the same way? The transport could send the CONNECT method to establish the TCP tunnel and then send the request after that. Of course, if the target request is based on HTTPS, the TLS handshake would start otherwi

Re: [go-nuts] Golang 1.19+ preemption model on a preemptive linux kernel?

In brief then, in the presence of os threads running on a kernel that can preempt threads, it is incorrect to assume that any two statements within a goroutine will run atomically (both run, or not at all), irrespective of the simplicity of those statements, or whether any function calls involve

Re: [go-nuts] Golang 1.19+ preemption model on a preemptive linux kernel?

The statement I made is actually a bit stronger than the one you confirmed: Even if the goroutines are using atomic load/store, the preemtive nature of the os threads could easily interrupt one goroutine between an atomic load and its use of that value, giving another goroutine the opportunity t
