[go-nuts] Issue with golang.design/x/clipboard

[Arie van Wingerden]

See my code attached!

My issue is that, after writing to the clipboard, I can only read the 
string I wrote back during the period I "sleep" after the write.

If I do not sleep, the clipboard immediately reverts to "empty".

Am I doing something wrong here?

TIA
Arie

[go-nuts] Issue with integration test coverage

[savita juyal]

Hello All,

I am trying to collect integration test coverage but its not generating 
covcounters file. Please looks steps I am following to generate covearge.

- *Build go binary* : go build -race -*cover* -o $(ROOT)/go/bin/appwithrace 
-ldflags "-X app/handler.proxyVersion=$(VERSION) -X 
app/handler.gitVersion=$(GITVERSION) -X app/handler.buildTime=$(BUILDTIME)" 
cmd/proxy/proxy.go

- *Run go binary* : ENABLE_TLS=false ENABLE_TLS_TO_DB=false 
LOAD_BALANCED=false *GOCOVERDIR=./coverage/int *./go/bin/appwithrace 2>&1 
>/dev/null &

- *Exit go program* : Kill -9 go_process_id

Now we only covmetadata file generated under the given path. Please me know 
what I am doing wrong or if I am missing something?

Regards
Savita Juyal

Hi,
I see that you have already provided a fix for this issue 
https://github.com/golang/glog/commit/9c9801e69114b582b12aa7010c75fe2105ae23b3
.
Any idea when you will make a new tag release with this fix?

Thanks for the report. The panic stems from the flag package trying to
call .String on the mentioned glog.vModuleFlag type. I'll fix this
internally and publish a new version soon.

Hi,

['Axel Wagner' via golang-nuts]

You are running into this: https://go.dev/doc/faq#covariant_types

> How could I do that?

You probably have to write a wrapper. Or change the concrete type to return
an interface. Or test using the concrete type, instead of using mocks.

[go-nuts] Issue implementing interface method that returns another interface

[Rick Schubert]

I am having a question about how to implement interfaces correctly in Go 
when it comes to third-party packages that use chained methods. I have 
compiled an example project below for you so that you can understand the 
problem.


package main

import (
myAPI "github.com/hashicorp/vault/api"
)

var myClient *myAPI.Client

type MyProvider interface {
GetClient() MyAPIClient
}

type MyAPIClient interface {
// I want to do this but it does not work
Logical() MyAPILogical
// This works though
// Logical() *myAPI.Logical
}

type MyAPILogical interface {
Write(path string, data map[string]interface{}) (*myAPI.Secret, error)
}

type Provider struct {}

func PublicFunctionIWantToTest(provider MyProvider) {
client := provider.GetClient()
// We normally do something here with the 'client' variable, but important
// is that we forward it later on
privateFunctionThatIsUsedInTheTest(client)
}

func privateFunctionThatIsUsedInTheTest(client MyAPIClient) (*myAPI.Secret, 
error) {
return client.Logical().Write(
"/here/goes/some/path",
map[string]interface{}{
"key": "value",
},
)
}

func NewProvider() MyProvider {
return Provider{}
}

func (p Provider) GetClient() MyAPIClient {
return myClient
}

// Empty function just so that this example can be built
func main() {}


As you can see, the package has a chained method Logical().Write() . Since 
I want to create tests for PublicFunctionIWantToTest, I want to pass down 
all the functionality as interface so that I can use 
https://vektra.github.io/mockery/ to create mocks for it.

Unfortunately, I am hitting an issue with my MyAPIClient and the 
MyAPILogical interface. Since I can see in the package's documentation 
(https://pkg.go.dev/github.com/hashicorp/vault/api@v1.8.1#Logical.Write) 
that the Logical() method returns a Logical instance, I want to make it so 
that interface method returns the other interface MyAPILogical (line 15). 
This does not work though, there is an error on line 47 in the GetClient() 
method saying that I would not implement the interface correctly. How could 
I do that?

cannot use myClient (variable of type *api.Client) as MyAPIClient value in 
return statement: *api.Client does not implement MyAPIClient (wrong type 
for method Logical)
have Logical() *api.Logical
want Logical() MyAPILogicalcompilerInvalidIfaceAssign

Thank you kindly

[go-nuts] Issue with regular expression processing

[sbezverk]

Hello,

 

I came across a strange behavior in regular expression processing, please see 
the following simple code which is supposed to match the second line of data 
variable.

 

https://go.dev/play/p/QPrNRuhCv8r

 

The matching data starts at the beginning of the 3rd line so I expect the 
pattern `^` + l + `\s+([0-9]+)\s+` would result in a match, but it does not. If 
I remove `^` from the regular expression, then the match is found. Running 
`grep -E` with regular expression which includes `^` also finds the expected 
match.

 

Appreciate some feedback. Is it a bug or I do something incorrectly?

 

Thank you

Serguei

Re: [go-nuts] Issue with go-git API

[Martin Schnabel]

Hi PK,

most of the time examples are single file programs to be used with go 
run. if you are inside the module root that covers all the dependencies 
(or decend into the relevant example folder) you can use `go run 
main.go` to run the example file.


I just tired it with the same repository and it works as expected and 
described.


have fun!

fmt.Println(errno) is throwing the error code.
Do you have any idea ?

Thanks in advance,

[go-nuts] Issue: x/net/html Node and attributes constructor function

[atd...@gmail.com]

Just wondering if people would feel it worthy to have COnstructor functions 
to create html.Nodes, attributes, and set attributes on html.Nodes.

I'm writing some kind of metaframework targeting the web and mobile (think 
flutter for Go) and basically finished the web target via wasm.

But I'd like to convert the app tree into an html node tree for static 
generation of pages (think isomorphic app server or whatever the 
terminology frontend dev use nowadays)

After having looked at different solutions, x/net/html seems simple enough 
albeit a bit lacking.

Maybe it is by design for people to build upon it though.

So, do I prepare PRs or just build on it for myself?

I didn't see any code. All I saw were two pictures that didn't make any
sense :-)

In other words, please post plain text or a link to play.golang.org.

Pretty much, yes.  A past-the-end pointer looks like a pointer to the
next object, and the write barrier can't tell the difference.

Hi all,

In this 
proposal 
https://github.com/golang/proposal/blob/master/design/24543-non-cooperative-preemption.md,
 
it is mentioned past-the-end pointer and the fact it should be avoided. My 
assumption is that it could lead to a bad memory tracking/cleaning since 
the write barriers keep track of the change in the pointers. Is that 
correct?

Thank you

[go-nuts] issue with yaml processing

[R Srinivasan]

I have the following fragment in an input yaml file:

contents: [
 '../etst1/date1from1' , 'var/lib/to1' ,
'from2' , 'to2'
  ]

My go struct for the above looks like:

type Config struct {
 Contents []string `yaml:"contents"`
}

I use the package gopkg.in/yaml.v3

when I unmarshal and immediately reverse Marshal and write it to a file, it 
is represented in a different syntax as in:

contents:
  - - ../test/date1from1
- /var/lib/to1
  - - from2
- to2

I suspect these are equivalent but 

is there a way I can get a reproduction of the input yaml. 

If it is not obvious, this is my first exploration of yaml. Pointers 
appreciated.

 Original  json format required:
 { "pos": [{ "lp" : "WISE-12", "lat": "-33,43565400", "lon" : 
 "-70,60552700", "speed" : "102" }] 
 } 

 Json autogenerated from: https://mholt.github.io/json-to-go/ (lazy 
 style but it works. Even more when my boss is surrounding like a shark! 
 jajaa)

 type AutoGenerated struct { Pos []struct { Lp string 
 `json:"license_plate"` Lat string `json:"lat"` Lon string `json:"lon"` 
 Speed string `json:"speed"` } `json:"pos"` }

 So I tried more fancy style but it doesn´t work:(

 type track struct{ Lp string `json:"license_plate"` Lat string 
 `json:"lat"` Lon string `json:"lon"`
 Speed string `json:"speed"`
 } type pos struct{ Position []track `json:"pos"` }

 x := pos{ Position:[{Lp:"DEMO" , 
 Lat:"-33.3244",Lon:"-33.391134",Speed:"80", } ]}

 Somebody gave me a hand with this:

 track := make(pos,1)
 track[0].Lp = "EEE"
 track[0].Lat = "-23.243423"
 track[0].Lon = "-24.2344123"
 track[0].Speed = "50"

 Data2Send := pos{track}

 But it doesn't keep "pos" when I check Data2Send with 
 fmt.Printf("%v",Data2Send).
 Any idea? "Is any out there?"

 Thanks

[go-nuts] issue on export a C static library from Go（CGO）via GCCGO compiler on IBM-AIX -PPC(unix) box

[Lei Ma]

HI team :

i am facing an issue on export a C static library from Go via GCCGO 
compiler on IBM-AIX -PPC(unix) box. 
my GO code(wrapper.go)  as   below :

package main

//#include 
//#include 
import "C"
import "fmt"

//export printHello
func printHello() {
fmt.Println("hello nuts!")
}


func main() {
// for c build
}

the command i used to compile it  is  : 
 go build -compiler gccgo -buildmode=c-archive -o caculator.a  -gccgoflags 
'-lgo -static' wrapper.go

then i got a  c static library  caculator.a , then  i use it in a c program 
as below :

#include 
#include 
#include "caculator.h"
int main()
{
  int a=12;
  int b=13;
  printf("Hello, let's test caculator!");
  printHello();
  printf("result:%d",12131231);
}

then i tried compile this c program with : gcc -o app  main.c caculator.a 
-pthread

then i got a exec file  app  
but  when  i tried to run it  , it seems run into a deadlock , nothing 
print  out 

the solution works great  on a 86_64 linux  box with  Go C compiler 
(non-GCCGO)...


got  stuck  with this issue above one week , any thought on this ?

thanks

Re: [go-nuts] Issue using json with array

[Tomás González Dowling]

Not sure if that was a question, Juan. But you can use Marshal method in
the encoding/json package to avoid using make. There are some examples in
the official docs: https://golang.org/pkg/encoding/json/#example_Marshal

Hope that it helps :)

fmt.Printf("%v",Data2Send).
Any idea? "Is any out there?"

Thanks

Re: [go-nuts] Issue with creating file on aws lambda

[Jim Ancona]

I'm pretty sure that the only writeable file system on Lambda in under
/tmp. You're not checking the error return from os.MkdirAll, but that call
is probably failing before you get to os.Create. Also keep in mind that
each Lambda instance is limited to 512 MB of /tmp space:

[go-nuts] Issue with creating file on aws lambda

[AE]

Hello,

I am trying to make function which will down file fro aws s3 and do some 
image resizing. I am having issue with os.Create, when I run locally on ec2 
machine it works fine but when I run on lambda directly I get error file 
not found 


package main
import ( 
"github.com/aws/aws-sdk-go/aws" 
"github.com/aws/aws-sdk-go/aws/session" 
"github.com/aws/aws-sdk-go/service/s3" 
"github.com/aws/aws-sdk-go/service/s3/s3manager" 
_ "github.com/aws/aws-lambda-go/lambda" 
_ "github.com/nfnt/resize" 
   _ "image/jpeg" 
"fmt" 
"os" 

) 
type MyEvent struct { 
Name string `json:"name"` 
}

func HandleRequest() (string, error) { 
runResize("5bba5c0f01e2f_dcadcc7139454bf6dba4cbd01a7c92f8.jpeg") 
return fmt.Sprintf("Hello"), nil 
} 

func main() { 
 //   lambda.Start(HandleRequest) 
runResize("5bba5c0f01e2f_dcadcc7139454bf6dba4cbd01a7c92f8.jpeg") 

} 

func runResize(item_name string) { 
bucket := "bucket" 
folder_name := "images/users/original/" 
folder_name_220x220 := "images/users/220x220/" 
folder_name_250x250 := "images/users/250x250/" 
folder_name_500x500 := "images/users/500x500/" 
folder_name_large := "images/users/large/" 


 

createFolder(folder_name) 
createFolder(folder_name_220x220) 
createFolder(folder_name_250x250) 
createFolder(folder_name_500x500) 
createFolder(folder_name_large) 

 

item := folder_name + item_name 

fmt.Printf("Creating file %q \n", item) 
file, err :=  os.Create(item) 

if err != nil { 

exitErrorf("Unable to open file %q", err) 

} 
defer file.Close() 
sess, _ := session.NewSession({ 
Region: aws.String("us-east-1")}, 
) 
downloader := s3manager.NewDownloader(sess) 
numBytes, err := downloader.Download(file, 
{ 
Bucket: aws.String(bucket), 
Key:aws.String(item), 
}) 

if err != nil { 

exitErrorf("Unable to download item %q, %v", item, err) 

} 
   fmt.Println("Processed", file.Name(), numBytes, "bytes")  
} 
func createFolder(folder_name string) { 
if _, err := os.Stat(folder_name); os.IsNotExist(err) { 
os.MkdirAll(folder_name, os.ModePerm) 
fmt.Printf("Folder created %q \n", folder_name) 
} 
} 

func exitErrorf(msg string, args ...interface{}) { 

fmt.Fprintf(os.Stderr, msg+"\n", args...) 

os.Exit(1) 

}



Here how I build the code for deployment


GOOS=linux go build -v -ldflags '-d -s -w' -a -tags netgo -installsuffix 
netgo -o resize && zip deployment.zip resize


and error I am getting 


Unable to open file "open 
images/users/original/5bba5c0f01e2f_dcadcc7139454bf6dba4cbd01a7c92f8.jpeg: 
no such file or directory"

This error i thrown on create on in LAMBDA

[go-nuts] issue ? httptest failed to bind newly released port

[leslie . qiwa]

Dear all,

I filed one issue at https://github.com/golang/go/issues/24818. This 
issue seems like not happened at regular repeating listen/close calls, but 
only at httptest. Sincenet.setDefaultListenerSockopts already set this 
socket option socket.SO_REUSEADDR, I expect app can reuse this port, or app 
should avoid this behavior? Welcome to hear your thought. Thanks!

Best Regards
Leslie

[go-nuts] Issue with log.V and log.${Level}Depth

[Xiaoyi Shi]

Hi there,

When combining V() and ${Level}Depth() together, the logging logic becomes
less
clear. For instance, with the retry function below:

```go
func Retry(fn func() error) error {
  var lastErr error
  for attempt := 0; attempt < maxRetries; attempt++ {
backoff.Sleep(attempt)
if lastErr = fn(); lastErr == nil {
  return nil
}
// Determined by -vmodule set for retry().
if glog.V(1) {
  // Using caller info at 1 level up in the call stack.
  glog.WarningDepth(1, fmt.Sprintf("Attempt %d failed: %v", attempt,
lastErr))
}
  }
  if glog.V(1) {
glog.WarningDepth(1, fmt.Sprintf("Exhausted %d retries: %v",
maxRetries, lastErr))
  }
  return lastErr
}
```

In this example, Retry() as a helper function, which performs backoff
retries of fn().
It logs in case fn() fails, but instead of logging with context of Retry()
function,
using the context of the Retry() caller will provide better insights for
debugging.

When use ${Level}Depth() with V(), I would expect the verbose status is
determined while
aware of the depth set. So that -vmodule set for the Retry() caller should
be used for
determine the return value of V().

I propose adding a function called `VDepth(level, depth)`, so that the user
may
hint which caller to use.

Best,
Xiaoyi

Re: [go-nuts] Issue with json unMarshall

If your field names match the JSON field names, you don't have to 
explicitly tag them.

Your struct has all unexported fields. So the json package can't see them.
You have to capitalize the field names.

[go-nuts] Issue with Goroutine and http.RedirectHandler

[Rejoy]

Hi,

I am trying to create a go routine to direct the request to another url:

go http.ListenAndServe(":8000", 
http.RedirectHandler("https://127.0.0.1:8001",301))

I had earler made a mistake and had typed in "https://127.0.0.1/:8001; for 
the url string.  But now after rectifying the mistake to the above, I am 
still being redirected to the incorrect url.

When I type in the url  ""https://127.0.0.1:8001;, the page is rendered 
correctly.

Is there a need to explicitly stop go routines. Strangely even after 
restarting the m/c, the request is being redirected incorrectly. 

Thanks
Rejoy

[go-nuts] Issue #5932 (net: do not wait on EAGAIN from lossy packet conn)

[anner]

Hi,

I'd like to respond to #5932 , but can't 
because it is locked.

Earlier we had issues (see comment 17), however it seems to be fixed in 
1.7.4 and also a couple of versions ago (1.5, 1.6).

The tested kernel version is:
Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.73-2+deb7u3 x86_64

I've used the source code from comment 17 to reproduce the issue.

Kind regards,
Anner van Hardenbroek

Re: [go-nuts] issue with sending JSON via HTTP

[Henrik Johansson]

It seems like you encode the valid json string?
If you have a string that is json you should be able to post the string as
is no?

Just make sure you set the application/json content type.

The wiki code is correct. r.URL.Path should begin with a slash, always.

I'm not sure what you're doing that is different. That wiki code is tested,
though.
