Yer replace is mentioned in the link I provided too and I’d seen that
thread, but as you can see from the amount of effort required I would
suggest that it’s currently not practical to have everyone go through that
process; particularly for tools when they just want to install and use not

I agree mostly with T L, and I say in the article in the section "Testing

.
The race detector will detect race conditions if they happen during the
execution of the tests. But, as they are race

1. I wouldn't say that there are several goroutines writing, as there are
several goroutines block in a mutex. Some might find this not important,
As for the readers being aware of a lock, that is not true either, as the lock
is hidden by encapsulation. (The last and best version doesn’t even need the
lock on the readers)

Hi Marcin,
I think https://play.golang.org/p/RiKi1PGVSvF is basically what I do with
atomic operations in my blog post

in
the section "Some experiments", and then using the wait group as I say

I will repeat this - and I meant no offense. You should read up on RWLocks
because your criticism is incorrect. Multiple Go readers can hold the Read lock
at the same time - so there are multiple writers adding to the channel
concurrently (but the channel impl uses a lock, so it’s not strictly

Hi Jasper,
Do you have some literature with that use. I honestly have googled:
No, please review this: https://play.golang.org/p/sPWrNhzRXKz There is no need to use the lock in Read()Encapsulation in this case means, the user of MultiWriterIntChan does not know it uses locks behind the scenes, nor does it need to know.Due to limitations of the playground, the code referenced

Hi
hex.EncodeString works!
The problem was the struct field types ([]byte) instead of string.
Thanks!

By encapsulation? Are you talking about
https://play.golang.org/p/YOwuYFiqtlf or other version of the code?
As I think someone already said, there is a need in the method Read for a
lock. And the read from the channel is done from that method. With your
pattern, the user of the hypothetical

same issue here:

Hello,
I am looking for a way to regularly update my Go module's direct
dependencies. Without specifying indirect dependencies myself: let my
direct dependencies specify what they need in their own go.mod.
After reading relevant documentation, I could only come up with this
partial
Hello Mihai,
To upgrade your direct dependencies to their latest release (with your
indirect dependencies using versions selected based on the requirements of
your direct dependencies), this should work in most cases:
go get $(go list -f '{{if not (or .Main .Indirect)}}{{.Path}}{{end}}' -m
Hello Guillaume,
I haven't had a chance to look at your example closely, but it seems you
have two modules defined on your local filesystem, with two go.mod files
total.
If that is what you are trying to do, one approach is to use a `replace`
directive to let one module know about the on-disk
