Yes, both of those seem to be using kernel modules :) Implementing kernel modules in Go would be ambitious, to say the least (at least in my opinion). On Wed, Nov 25, 2020 at 11:28 PM Chris Lu wrote: > Hi, Axel, > > Thanks for answering! I was checking CEPH, Lustre, etc. Here is one > example: >

[go-nuts] concurrency safety

How would you cal "thread-safety" in Go? Go doesn't have threads so the term "thread-safety" sounds bit off. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group. To unsubscribe from this group and stop receiving emails from it, send an email to gola

Re: [go-nuts] How to plug git version when using "go get" to fetch a cli?

The version is really a property of the code (and binary) not the repository. I think it's better to put the version in the code that is committed. This is the approach taken by packages such as protobuf https://pkg.go.dev/

Re: [go-nuts] How to plug git version when using "go get" to fetch a cli?

using `runtime/debug` this will return a tagged or pseudo version when retrieved through `go get` in module mode, in other cases it will return `(devel)` i, _ := debug.ReadBuildInfo() fmt.Println(i.Main.Version) On Wednesday, November 25, 2020 at 7:14:45 PM UTC+1 changkun wrote: > That is real

That is really unfortunate. Is there any alternative solution so that I can burn at least the version information to the binary when a user uses `go get`? On Wednesday, November 25, 2020 at 6:36:17 PM UTC+1 Jan Mercl wrote: > On Wed, Nov 25, 2020 at 6:25 PM changkun wrote: > > > As far as I kn

[go-nuts] How to plug git version when using "go get" to fetch a cli?

Hi golang-nuts, As far as I know, there are two approaches to add extra information at build time: 1. using -ldflags="-X path/pkg.Var=${ENV_VAR}", in a Makefile 2. using `go generate ./...`, before `go build` These approaches are good as it is if I build my binary and distribute it to other use

Dear All, I am glad to be here and I hope to learn and share valuable experiences. So my entrance question is regarding the Syslog theme. Maybe someone may help with the following problems: within the gRPC project 1. I would like to catch data from the command line or Syslog-port and adapt pa

Hi, Is there a way to set a hard limit on the max heap size a process is allowed to consume, from within it? It's almost never a problem for a process to consume as much memory as is available, however, I've ran into real-life cases in a k8s environment, where a pod with a Go process will get

Re: [go-nuts] mount remote storage without FUSE

Can you link to an example C project? Theoretically, everything that's possible in C should also be possible in Go. However, I'm unaware of a method to mount a userspace filesystem except FUSE. So as far as I'm aware, you'd need a kernel module for that (and, yeah, doing that with Go would probably

Hi, Gophers (who are also good in C), Currently I am using FUSE to mount and write to remote storage. The library I am using is Basil Fuse. The performance is good as far as FUSE can go. User -> file.write() -> Linux Kernel -> Virtual File System -> libfuse -> FUSE -> DFS Client(in Go) -> Remo
