Re: [go-nuts] atomic.Add*() doesn't produce unique values

I wrote a less-sophisticated version of your test, then realized I'd misspent my time; all I needed was to change the atomic.Add*() to a mutex-protected counter, and see whether my app still failed; it did. But since you took the trouble, I read your code, and would like to understand your coll

Sigh. I overlooked the riddle and took it as a straight question. Typical for me all my life. (once considered making a T-shirt saying "answers rhetorical questions"). Mild chagrin here... (P.S. sorry for bad typing. Keyboard's B and SHIFT keys are roken broken.) On Sat, Nov 30, 2019 at 5:48 PM an

As a follow-up, some more timing: *47088064 atomic increments/sec (my original email above for heavy synchronization conflict incrementing)* 142049067 atomic increments/sec when each goroutine has its own atomic update target. (Not testing global synchronization/mutex, just the overhead of conges

[go-nuts] Where is the middle of Brazil?

When I was a kid I asked my teacher why my country capital had been moved from Rio de Janeiro to Brasilia. She said the reason was Brasilia is right in the middle of our territory, that way our president could take care of our entire country more effectively. I accepted that answer. Many years

Re: [go-nuts] C variadic macro equivalent in Golang?

You might refer to... https://blog.learngoprogramming.com/golang-variadic-funcs-how-to-patterns-369408f19085 ...to better appreciate Robert's advice. As he suggested, a variadic Go function accepting a slice of the special, magic "empty interface" type ("interface{}") can indeed do anything. The

Re: [go-nuts] C variadic macro equivalent in Golang?

Thanks, but then you would have to define the interface beforehand for any argument type. And there are a lot: format strings, strings, characters, integers of different size, floating-pont numbers, file-ids Meanwhile I found this discussion: https://github.com/golang/go/issues/18605 which hints

[go-nuts] C variadic macro equivalent in Golang?

C allows comma-separated argument lists via variadic macros. Whereas AFAIK golang allows only variadic arguments of the same type. (Please excuse if I am wrong, I am considering myself a golang newbie) C demo program that prints: -- -- 1 and 1 1 and 1 // ## C variadic macro test #include

Re: [go-nuts] atomic.Add*() doesn't produce unique values

The stress test for my app fails frequently with what looks like a collision in atomic.AddUint64() results, so I wondered whether I had misunderstood atomic-add. So far I can't reproduce it with a small program, so I've probably misunderstood my app :-) On Friday, November 29, 2019 at 6:41:39
