If you compile it to WebAssembly, it will works under the single thread model. However, there are still multi *goroutine *be created, it was designed to. 在2024年9月10日星期二 UTC+8 21:54:56 写道： > Hello, > > Maybe the question has already been asked, but I would be glad to have > your feedback. > >

[go-nuts] Why is there a huge gap between the memory profile's inuse_space in pprof and the externally obtained memory footprint?

I'm working on the project https://github.com/Zxilly/go-size-analyzer, a program that can be very memory intensive, so I've written some scripts to fetch the pprof file during integration testing, and I'm using python's psutil to read the cpu and memory usage to automatically plot into the im

[go-nuts] Re: Reproducible builds with CGO

golang will embed the path of the source file into the binary, also the .gopclntab will contains the path. try use -trimpath and see if there's any change. 在2024年4月27日星期六 UTC+8 01:28:05 写道： > Hi All, > > *Does anybody have experience in how the use of CGO and dynamic linking > may affect the re

[go-nuts] Which part of go compiler set the symbol "runtime.text" in the final build?

Yesterday, I reported an issue on debug/gosym at issues/65232 regarding the difference between the symbol table and gopclntab. A member of the Go team informed me that the start of the .text segment is not always kept the same as 'runtime.text' value. I am curious about how the compiler sets th
