Re: [go-nuts] How to make UDP server performance better?

The time spent in the syscall would include time blocked, waiting for a packet to arrive. I would look at the other parts of the profile for possible improvements. The kernel may also be dropping packets if there is not enough buffer space to receive them into; see the SO_RCVBUF socket option. Mayb

[go-nuts] Re: Custom types for use with range (Go 2)

Sorry for late reply: yes, it’s sugar, and a first implementation might be to have the compiler simply rewrite it like a macro, as in your example. And I realize that my example was more verbose than need be. We don’t call an iterator on arrays, maps, etc, so my example should have been: for t

Re: [go-nuts] Closing os.Stdin while trying to read from it?

Thanks for the great info! Out of curiosity, how is Go handling ctrl+d (sending EOF to stdin) right now? Is it part of the special case? A more generic way to ask this is: Is it possible to programmatically tell os.Stdin that we've reached EOF while you're trying to read from it? On Friday,

Do you have to use plugins? I would avoid them whenever possible. What benefit do you expect to get from using them? On Sun, Mar 11, 2018 at 1:03 AM Jay Guo wrote: > Bump.. any thoughts? Thanks! > > - J > > > On Thursday, March 8, 2018 at 2:03:37 PM UTC+8, Jay Guo wrote: >> >> Golang gurus, >> >

[go-nuts] Closing os.Stdin while trying to read from it?

Hey folks, I'm trying to figure out how to cancel reading from stdin programmatically. Basically the same way that ctrl+d works on OSX. I would have thought this would work, but this program will just run forever: package main import ( "io/ioutil" "os" "time" ) func main() { go func()

[go-nuts] Re: Possible to stream database/sql rows to text/template?

Ah! Should have thought of that. After implementing it, however, I realized that it's not very conducive to HTTP requests, in which the Content-Size header is expected to be sent, and thus, how can I know the content size of a response until I've rendered the whole thing? Thanks anyways! --

[go-nuts] Possible to stream database/sql rows to text/template?

I'm interested in streaming results from a *database/sql* query to a template rendered with *html/template*. More specifically, for performance reasons, I'm interested in streaming an array of results from the database straight to text/template without allocating a slice beforehand. My idea is
