Re: [go-nuts] Issues with time.Time

Thanks for the feedback. I should explain that efficiency is not (currently) a problem. The thing I love about Go is that there is always a simple and obvious (and reasonably efficient) way to do things. I'm currently call time.Now().UTC() no more than a few thousand times per second and store

Re: [go-nuts] Data race in sql package

I'm guessing that Michal is flagging is there no way to write safe code if your using stmt.QueryContext(ctx) and rows.Scan into a sql.RawBytes as QueryContext kicks off a go routine that monitors the ctx, closing rows if cancelled and that ctx can be cancelled at any time. The only thing that spri

Re: [go-nuts] doc comment links to non-imported packages due to import cycles

Unfortunately, I cannot see how this is supposed to work with pkgsite. I tried relative URLs, and these do not get recognized as valid links. So I would need to hardwire the links to always refer to Google's pkgsite, which defeats any different deployment and any host-local deployment while wor

[go-nuts] Data race in sql package

Hello, I have a code snippet equivalent to this one: rows, err := stmt.QueryContext(ctx) if err != nil { return info, nil, err } defer rows.Close() var data sql.RawBytes for rows.Next() { err = rows.Scan(&data) if err != nil { return nil, err } // if ctx is canceled ar

[go-nuts] [External] Differences between unmarshaling with encoding/json and encoding/protojson

Hi all, Is there a comprehensive list of differences between how json.NewDecoder(r.Body).Decode(&req) and protojson.Unmarshal(req.Bytes(), pbObj) unmarshals JSON payloads? Switching from json.NewDecoder(r.Body).Decode(&req) to protojson.Unmarshal(req.Bytes(), pbObj) returned an error due to a

Hi All Is there any reference implementation of GUI based workflow engine similar to BPEL or Oracle OSM like No-code system built on golang. Thanks C.R.Bala On Friday, April 22, 2022 at 10:23:56 AM UTC+5:30 Ankush Thakur wrote: > As of 2022, Temporal is an amazing alternative: https://temporal

Re: [go-nuts] Re: Cannot instantiate T(ype) passed as pointer T?

Thanks, actually that's what I was looking for. Don't have much experience using generics (like 2 days) but looks rather inconvinient to do that. This pattern is convinient for you and you're using it in your code? You think there are plans to introducing some feature which will allow to work w
