[go-nuts] How likely is a data race to allow arbitrary code execution?

I know that in Go a data race is undefined behavior. How likely is the undefined behavior likely to result in an exploitable security bug, where "exploitable" means more than just denial-of-service? I am looking for qualitative estimates here. Is it the kind of bug that would be almost

Hi Nate, Thanks for the suggestions. We've definitely backed off appending to a separate value. Our code ended up looking like this (the requirements were actually a bit more complex than the core example): func (n Namespace) Combine(with ...Namespace) Namespace { // Benchmarks show it's

[go-nuts] Re: Strange results from append

it is almost always a bad idea to use append and assign the result to a different value than the thing you're appending to. i.e. always do this: ns = append(ns, foo...) and don't do this: bar := append(ns, foo...) The thing is, that in that last line, like in your code, bar and ns *might*

In your example, MyError2 does not have an Error() method so it is not called. From the fmt package docs (golang.org/pkg/fmt): - 3. If the %v verb is used with the # flag (%#v) and the operand implements the GoStringer interface, that will be invoked. - If the format (which is implicitly

I agree that the only thing that can make the two examples act differently should be the capacity of ns. The fact is that both versions are buggy, in the sense that one append can in general overwrite the other. If ns1 and ns2 are conceptually two different slices, it's better to ensure that

Thanks Roberto. That certainly explains the second result, so it perhaps updates my "expected" result to be the second and not the first. Unfortunately it does not necessarily explain why the first result acts differently. I can reproduce what you describe in go playground, but not the

[go-nuts] Re: Strange results from append

https://golang.org/pkg/builtin/#append If the initial slice ns has enough capacity, it will not be reallocated, but only resliced and modified in place. So, in your second example, ns1 and ns2 can end up being two slices that share the same underlying array. On Friday, July 15, 2016 at 7:28:32

Re: [go-nuts] What does -fm mean as a suffix for a runtime function name?

The semantic difference is that Type.Method takes the receiver as its first argument, whereas value.Method does not (the value is part of the closure context, which is why creating a function in this way incurs an allocation). On 15 Jul 2016 07:16, "Gregory Golberg" wrote: >

I'd like to second this! Also have the linux tree in $GOPATH, and ever since I put it there goimports slowed down. Some kind of subtree exclusion mechanism would be great. Nevertheless, thank you for your work on probably the most useful Go tool out there, Brad! I can't imagine programming

Awesome! For me it brings the CPU time from 6.5s to 3s. Wall from 2.9s to 2s. A noticable improvement. One thing that still makes it slow for me (2s instead of 500ms, I just tested), is that I have several of deep trees which aren't go code in my $GOPATH/src. To name a few: linux, clang, llvm.
