Re: [go-nuts] Performance for concurrent requests

I wonder a bit about io.ReadAll versus constructing a JSON Decoder. In general, though, using pprof is the best way to start to break down a question like this. Would the actual workload involve more structured JSON, or more computation with decoded values? On Friday, December 2, 2022 at 7:31:5

[go-nuts] Performance for concurrent requests

Hi guys, I've been working on some experiments with different web application stacks to check their performances under a specific scenario: one in which I have to make several concurrent requests and then gather the results together (in order) and throw them out as JSON in the response body. (T

Re: [go-nuts] gRPC for web applications with millions of users

Hi all, I've built a streaming RPC library compatible with grpc Protobuf service definitions that can do bidirectional streaming to the web browser over any AsyncIterable channel, currently using WebSockets but can also use Message channel to webassembly and other messaging approaches. https://gi

Re: [go-nuts] How can I use go with Modules

My 2cents here. One of the most terrible examples of pre-mod repos I've encountered are Docker's engine repos, subsuming also the repos moved into the moby realm: they mostly lack module information and they break upon checking them out on master or go getting them and trying to build, even on

[go-nuts] Re: [ANN] new linter for "mixed pointer and value receivers"

IMHO it might be of broader use to lint the cases where a value receiver is used and there are assignments to it or its fields ... or is this already caught by ineffassign? The recommendation leads to slightly "ugly" situations on a regular basis to enforce a pointer receiver on the Stringer me

[go-nuts] Re: gRPC for web applications with millions of users

Just checking that you came across this already? https://grpc.io/blog/state-of-grpc-web/ gRPC can't be implemented natively in browsers. You can sending something gRPC-like and then convert it back to gRPC at the server. But for bi-directional streaming, I think you need to look at Websockets o

[go-nuts] Fetch pseudo-versions

Hi, this question is a little bit weird, but for a project I need to list all versions of a golang package. Currently I'm doing it with the golang proxy, and the list endpoint, but it has one issue, it does not return pseudo versions. Do you have any idea o how can I access this information? so

Re: [go-nuts] Go Memory Model question

The way I read the memory model, this program can print 01, 00, and 11, but not 10. This is because goroutine creation creates a synchronized before relationship between x=1 and x=0, so even though there is a race, x=0 happens before x=1. On Fri, Dec 2, 2022 at 6:56 AM のびしー wrote: > > I believe

Hi, I have used gRPC for some simple applications, where the server is in Golang and the client is also another golang application. I have primarily worked in the backend and have done a lot of gRPC communication among the backend services using the likes of gRPC streams and golang. Now for th

I believe your example is basically equivalent to the ones in https://go.dev/ref/mem#badsync which also contains an explanation of how the memory model implies this (or rather, how it does not imply the opposite). On Fri, Dec 2, 2022, 13:11 のびしー wrote: > Hello, I have another question regarding
