[go-nuts] Re: How to find optimal value for GOGC?

Interesting article. However, it does not describe the script/bench to find the best value, from 100 to 20,000, in increments of 100. -- 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

[go-nuts] Large number of goroutines on PowerPC

Hi, I'm working on a software for a 32-bit PowerPC processor. Since there is no Go support for it, I'm using gccgo. However, I've noticed that it's not possible to use a large number of goroutines since each one takes around 2 MB of memory. From what I understand, this is the stack space

[go-nuts] Re: test debugging woes

Some ideas: - I assume the code isn't public? If it is, you might share it - Are you running `go test -v` for verbose logging? - Try fmt.Printf - Try adding printing lines at points down the stack leading up to the point you think is failing, to make sure the code is actually running. - Put a

[go-nuts] context.C and context.BG

I don't have numbers, but context must be one of the most commonly used imports/types in my code. It shows up many function signatures. We try to use it for all cancelation. Would it make sense to add an alias "C" to the type "Context"? And maybe "BG" for Background()? Also, is there a

[go-nuts] Easy access to #golang

Hi all, I don't like signing up for accounts, or having to jump through hoops (even if they're relatively straight forward hoops) to get an invite to something that should just be public. Also, some people seem to like web clients, so here's a quick and easy way to access the #golang channel on

[go-nuts] Should net.Conn transform function retain the original data segmentation?

Hi all, To clarify, a net.Conn transform function transforms data write to/read from a connection, an example is as follow: type TransformedConn struct { net.Conn} func (c *TransformedConn) Read(p []byte) (int, error) { n, err := c.Conn.Read(p) transform(p) return n, err} func (c

[go-nuts] Re: test debugging woes

You could try using Delve (https://github.com/derekparker/delve) to actually step through and inspect the process during execution to avoid having to put print statements everywhere. Similar to the Go command, you can run `dlv test` and begin stepping through your test binary. On Thursday,

[go-nuts] test debugging woes

I wish I could help you, but your description of the problem could not be more vague. Your post can be rewritten as "problem pls help". What library is this? Is it on GitHub? Can we look at it? What section of code is returning nil? Is nil the problem? Or is there a panic? What's your code

[go-nuts] Flagging lazy-loaded fields as being unsafe to access directly

I'm trying to figure out a way to best signal to other developers maintaining a single package that a field is unsafe to access directly. In this case, it's being lazily loaded, and the only way to ensure it will be properly loaded is to access the method wrapper rather than directly

[go-nuts] Google Cloud Golang SDK authentication

I am trying to automate the VM and Network resource creation using GCD Client API. I do not want to use Google OAuth as the user has to generate token every time. I used AWS SDK and it can be invoked by simply using AccessKey and Secret Key. Is there any authentication method that does not

[go-nuts] Re: Flagging lazy-loaded fields as being unsafe to access directly

In Go, lowercase identifiers are not visible outside the package in which they are defined (ref: Exported identifiers ). Your example declares foo in the main package but I assume your real code would be in its own package. What you can do is

[go-nuts] Bug report github.com/golang/glog

For the flag "log_backtrace_at" the flag expects "" for an empty value when calling Set(), but .String() will return ":0" when the value is empty. This results in a different "emtpy" value being generated by String() than is accepted by Set(). The following code will reproduce the issue. *Output

[go-nuts] Re: context.C and context.BG

I've found a hint. Apparently, both context.TODO and context.Background share a common implementation but they need distinct addresses. See https://golang.org/src/context/context.go#L168 So they cannot be constants because then they would not have an address. They cannot be variables because
