[go-nuts] Re: Migrating from a classic OO pattern

First link in my first reply didn't use encapsulation. It gave Dog as parameter. Also not sure how golang internals work but when you encapsulate something thats probably new heap allocation. I know it's tempting to use OO patterns (classes) but golang has very powerful interface system and I

Re: [go-nuts] Re: How can I distribute incoming HTTP request to 5 asynchronous workers?

If one incoming HTTP request should be sent to 5 workers async, See *solution #5* for similar problem/solution - http://rodaine.com/2015/04/async-split-io-reader-in-golang/ . A video file is required to be processed in multiple formats where io.MultiWriter is used to send all data asynchronously

[go-nuts] Heap fragmentation: HeapProfile reported memory vs Memstats.HeapInUse

I am observing Memstats.HeapInUse of 50GB while a heap profile reports only 24GB. I tried increasing the heapprofile rate to 1KB and still I notice the same behavior. I added an app level accounting of memory usage and that also reports close to 24GB. This makes me think that this could be memory

[go-nuts] Re: Migrating from a classic OO pattern

Have you considered the possibility of splitting the prepare-and-attack method into prepare and attack respectively? Even in a OO language, I generally try to avoid a base class being dependent on its subclasses. The subclasses may depend on the base class, but not the other way around. 2-ways

My approach to mimic OOP behavior would be something like this: https://play.golang.org/p/QQvWxfOiMB It's funny how hard was to learn OOP and how easy was to unlearn it. To the present day I never had to do such gymnastic to program using Go. Not even once. -- You received this message because

[go-nuts] Re: How can I distribute incoming HTTP request to 5 asynchronous workers?

I read whole request body. Pack to some structure. Send to a message queue (RabbitMQ, Kafka, Google Pub/Sub). MQ services allow to configure a topic/channel to multiplex a msg to all receivers (in PubSub you would create multiple subscriptions for a given topic

In each of the handlers in an API I have, I first unmarshal the JSON request, and then validate the resulting struct. There are a few cases where I am able to pick up a correctable error in the validation code, but I'm not sure whether it's good practice to correct the error in the input

[go-nuts] Re: About "Declaring Empty Slices" of CodeReviewComments

None of those values are escaping or being used. Your only allocation is probably the call to fmt.Fprint. This isn't something that really needs a benchmark, it should be obvious that t is nil in `var t []string`, and t is not nil in `t := []string{}`. The former doesn't allocate a slice
