playground - timeout running go build [...] Could I solve it❓
The Playground is a playground and not a build server or an application server.
I'm trying to run doctest via its API from a thread using forkIO:...

Unfortunately you can't easily capture or redirect stdout and stderr for Haskell programs. Various hacks exist such as the System.Posix.Redirect or System.IO.Silently libraries, but they have a pile of caveats such as
- being POSIX-only, and
- messing with the file descriptors for your entire process, so they are not thread-safe and might interfere with other use of the handles.
In my experience the best thing to do is run your code in a MonadLogger monad. This offers a lot of control over where the log messages go: when you invoke the monad you can use
runChanLoggingT, etc. or an arbitrary
IO function of your own to handle the messages.
If you use a logging monad transformer, you'll want to import a lifted version of
bracket to use with it. I really like using Control.Exception.Safe in any place you would normally use
Control.Exception (for the liftedness and other safety reasons).

So the problem lied with wrong imports.
Deployments are defined in
apps/v1beta2. What I was doing was importing
"k8s.io/api/apps/v1beta1". I needed to change it to
Also for fetching that I needed to refer to
clientset.AppsV1beta2() instead of
Following this example of using go-micro. When I do a
go mod init github.com/username/blahblah followed by a go get -u I get this in my go.mod file:
ANSWERAnswered 2020-May-21 at 23:59
Its a bug with version inconsistency between go-micro and grpc. About a week ago I tried to follow the tutorial which you mention and got same error. If you want to fix the error above please follow the interactions below the link: https://github.com/etcd-io/etcd/issues/11563.
In additionally I recommend you just build grpc service without go-micro, due to version inconsistency.
I have a Linux Kernel Module that checks for the presence of a specific USB device and performs a printk upon a match. This code works fine and performs as i expect....
ANSWERAnswered 2020-May-10 at 08:35
The function that handled the matching used a different alert level for the printk function. As such, the messages were not displayed to the console at that stage in the boot process.
When I run
go get -u github.com/onsi/ginkgo/ginkgo
till yesterday I had no issues. Specifically with
fsnotify the output was like below
ANSWERAnswered 2020-Mar-12 at 18:09
Some module in the transitive dependencies of
github.com/onsi/ginkgo/ginkgo added a requirement on some version of
gopkg.in/fsnotify.v1, which resolves to the repository hosted at
go.mod file in that repository declares its canonical import path to be
If you are using Go 1.14, the rest of the error message (which seems to be truncated) should tell you exactly which dependency is using the non-canonical path. The long-term fix is to move that dependency over to the canonical path and upgrade your other dependencies such that
gopkg.in/fsnotify.v1 is no longer required.
I see a couple other people with the same issue however none of the solutions worked for me. The following commands+outputs are mainly what I have tried. I am posting 1) because I have been stuck on this for some time and 2) I wanted to leave a comment on another post but I have no reputation :(
I have reinstalled my os (arch linux), keeping only my home files however I deleted .stack, .ghc, and .cabal folders.
yay -S xmonad xmonad-contrib
stack install xmonad xmonad-contrib
sudo ghc-pkg recache

Sounds like an issue with cabal - I think there are some packaging difficulties on Arch Linux.
As an alternative, you can manually build a Haskell project with your specific xmonad config, once you know this builds correctly, you can create a
~/.xmonad/build shell file, and in here trigger a build to your xmonad config/application.
So the contents of
build might be:
I've been working with examples trying to get my first "go routine" running and while I got it running, it won't work as prescribed by the go documentation with the timer.Reset() function.
In my case I believe that the way I am doing it is just fine because I don't actually care what's in the chan buffer, if anything. All as this is meant to do is trigger
case <-tmr.C: if anything happened on
case _, ok := <-watcher.Events: and then all goes quiet for at least one second. The reason for this is that
case _, ok := <-watcher.Events: can get from one to dozens of events microseconds apart and I only care once they are all done and things have settled down again.
However I'm concerned that doing it the way that the documentation says you "must do" doesn't work. If I knew go better I would say the documentation is flawed because it assumes there is something in the buffer when there may not be but I don't know go well enough to have confidence in making that determination so I'm hoping some experts out there can enlighten me.
Below is the code. I haven't put this up on playground because I would have to do some cleaning up (remove calls to other parts of the program) and I'm not sure how I would make it react to filesystem changes for showing it working.
I've clearly marked in the code which alternative works and which doesn't....

You create a timer and you stop it immediately:
I want to change config of log on Golang application which run on K8S, I’ve tried the following code locally and it works as expected I'm using viper to watch for config file changes
This is the config map with the log configuration...
ANSWERAnswered 2019-Sep-14 at 15:55
I understand that viper can help with live changing out of configuration without restarting your app using the
OnConfigChange event, but have you tried setting the log level in your base ConfigMap and then starting up the app, just to make sure it's not an issue with the
OnConfigChange event firing and your particular config in k8s (and not your local environment where you've tested it works).
Lastly, what is the difference between your local test environment (where this is working) and the other environment where this is not working?
Are there any environment variables that might be affecting this differently in the one environment?
I want to do some watch when env variable/ config property value is changed
I’ve found viper which should support this scenario but didn't able
to make it work.
I see that the
OnConfigChange is called but the value from config
is not taken from the config when it change. The config is loaded successfully
I’ve created a sample to demonstrate the issue.
ANSWERAnswered 2019-Sep-09 at 12:44
There is nothing wrong with your code as far as I can see since
fsnotify truly does trigger. So the culprit has to be in parsing. The first call to
setLogLevel(c.GetLogLevel()) outside your
onConfigChange callback returns an incorrect value. Change the contents of your yaml file to just
