[go-nuts] Re: Named results allocated on stack instead of register?

It looks this is related to code inlining. If we add //go:noinline directive for the two functions, then they have no performance difference. On Monday, September 20, 2021 at 12:39:51 PM UTC-4 tapi...@gmail.com wrote: > Sometimes, a function with named results is slower. > For example:

Hello, Thanks for this, and also sorry for the lazy question. My testing on my machine indicates a limit of 2GB total limit on compile: too much data in section SXCOFFTOC (over 2e+09 bytes) too much data in section SDATA (over 2e+09 bytes) I have built a bash script that creates large random

[go-nuts] [ANN] Pack: Interfaces for LZ77-based data compression

Many data-compression schemes are conceptually composed of two steps: LZ77 (finding repeated sequences) and entropy encoding. But I've never found a compression library that treats those steps as separate components. So I made one: github.com/andybalholm/pack. It defines interfaces for the two

Trees although better in general than template still have one critical disadvantage: it is hard to control a code they produces.I tried approaches with templates, line by line and trees. Line by line is generally the best of them. понедельник, 20 сентября 2021 г. в 23:15:22 UTC+3,

Thanks. I am testing this with an increasing number of 1GB files. At 3 files, and I am getting this error: compile: writing output: write $WORK/b001/_pkg_.a: no space left on device I haven't been able to find how to change $WORK to point to a larger partition. Suggestions? Oh, running:

Re: [go-nuts] Re: Generating go code using go templates

Yes. Generating large portions of code via templates is going to be hard. Especially reusing and maintaining it. There is an excellent library called jennifer - https://github.com/dave/jennifer that lets you generate Go code by building the syntax tree. The examples make it super simple to get

Re: [go-nuts] Re: Generating go code using go templates

I'm writing a code generator from protobuf via templates and i can say - debugging it is very hard. When you have big files you can't check syntax easily, don't know how it looks and if you have errors in the template it is really hard to fix them. So the protoc-gen-go case is preferable. вс, 19

[go-nuts] Re: setuid root

OK -=- My mistake. When you setuid a program it sets the user to the owner of the file. So I owned the file, so it would run as me. When I did a chown root myapplication -- it runs like it should. Thanks everyone for the help. On Monday, September 20, 2021 at 1:54:33 PM UTC-4 Rich wrote: >

[go-nuts] Named results allocated on stack instead of register?

Sometimes, a function with named results is slower. For example: https://play.golang.org/p/wvWkfSRqDLr The generated directives are almost the same for the two functions with a named and unnamed result, except one difference. For the function with the named result, the result represents as "".ret

Try: cmd:=exec.Command("id") If it's definitely running as root then it could be other system-level restrictions: SELinux for example. If so, "dmesg" output may give you a clue, logging the policy violation. On Monday, 20 September 2021 at 16:20:39 UTC+1 Tamás Gulácsi wrote: > You mean

I am trying to create a go program so that I can peform an action that is more complex than the example I have below. I can't give sudo right so run the application due to some policy we have at work that certain groups can only have read permissions. The company also have a policy that states
