This is not how go test should be invoked. You just need to do go test
in the directory that you package lives in.

See https://pkg.go.dev/cmd/go#hdr-Test_packages

Re: [go-nuts] where is GOROOT set?

[pat2...@gmail.com]

Here I clear it, same result:

pfarrell@Alien15:~/whome/sandbox/gows/src/github.com/pfarrell51/cmd$ export 
GOROOT=
pfarrell@Alien15:~/whome/sandbox/gows/src/github.com/pfarrell51/cmd$ 
printenv GOROOT

pfarrell@Alien15:~/whome/sandbox/gows/src/github.com/pfarrell51/cmd$ go 
test treesort_test.go
# command-line-arguments
treesort_test.go:11:2: package treesort is not in GOROOT (C:\Program 
Files\Go\src\treesort)
FAILcommand-line-arguments [setup failed]
FAIL

Interesting: even though I cleared it to bash, it still shows up as being 
set in go

pfarrell@Alien15:~/whome/sandbox/gows/src/github.com/pfarrell51/cmd$ go env
set GO111MODULE=
set GOENV=C:\Users\pfarrell\AppData\Roaming\go\env
set GOPATH=C:\Users\pfarrell\go
set GOROOT=C:\Program Files\Go

In general you should never set GOROOT.  It's a special purpose hook
that is almost never needed.

What happens if you don't set it in the environment?

[go-nuts] where is GOROOT set?

[pat2...@gmail.com]

I'm missing something fundamental.
I have set GOROOT to my current directory, which contains my go source files
but I can't test a trivial program

treesort_test.go:11:2: package treesort is not in GOROOT (C:\Program 
Files\Go\src\treesort)

It looks like the value of the GOROOT variable is set to a different value
inside go itself, and not to the value that the shell sees.

(the program is treesort from the Kernigan and Donovan book)
// Copyright © 2016 Alan A. A. Donovan & Brian W. Kernighan.
// License: https://creativecommons.org/licenses/by-nc-sa/4.0/
// See page 101.

Sorry for the long PWD, but I'm trying to keep these trivial programs in 
github
and the path seems to be required.

pfarrell@Alien15:~/whome/sandbox/gows/src/github.com/pfarrell51/cmd$ echo 
$GOROOT
/home/pfarrell/whome/sandbox/gows/src/github.com/pfarrell51/cmd

pfarrell@Alien15:~/whome/sandbox/gows/src/github.com/pfarrell51/cmd$ 
printenv GOROOT
/home/pfarrell/whome/sandbox/gows/src/github.com/pfarrell51/cmd

This has to be something trivial that I'm doing wrong
Thanks

[go-nuts] X509 subject attributes are encoded as PRINTABLESTRING instead of UTF8STRING

[Atul Mundlik]

Hi All,
First post on the group,

I am using  go version go1.18.4 darwin/arm64.
I am trying to create X509 certificate with following code.

var COMMON_NAME = asn1.ObjectIdentifier([]int{2, 5, 4, 3})
 serial := new(big.Int).SetUint64(1)

subjectExtraNames = append(subjectExtraNames, 
pkix.AttributeTypeAndValue{Type: COMMON_NAME, Value: "golang"})

caCertTemplate := &x509.Certificate{
SerialNumber: 1,
IsCA: true,
NotBefore: time.Now(),
Subject: pkix.Name{ExtraNames: pkixAttrTypeValue},
NotAfter: time.Now().AddDate(10, 0, 0),

KeyUsage: x509.KeyUsageDigitalSignature | x509.KeyUsageCertSign,
BasicConstraintsValid: true,
}

when I inspect the created certificate using asn1parse -in 

   31:d=4  hl=2 l=  13 cons: SEQUENCE  
   33:d=5  hl=2 l=   3 prim: OBJECT:commonName
   38:d=5  hl=2 l=   6 prim: *PRINTABLESTRING*   :golang
the common name is *PRINTABLESTRING* and not the *UTF8STRING.*

As i understand, golang strings are utf8 default then why it is not *UTF8STRING 
?*

However, in above code when i use below to create certificate
subjectExtraNames = append(subjectExtraNames, 
pkix.AttributeTypeAndValue{Type: COMMON_NAME, Value: "é um"})
and when I inspect certificate then it shows *UTF8STRING *for* é um"*

If this is how it is then is there a way to get a string without special 
characters as *UTF8STRING *in certificate?

[go-nuts] [ANN] go-xmlstruct: generate Go structs from multiple XML documents

[twp...@gmail.com]

There are a few existing XML document-to-Go struct generators, but none of 
them had all of the following features:

* Taking multiple XML documents as input.
* Generating correct field types.
* Customizable field names.
* Handling optional and repeated elements.
* Ignoring whitespace.

If you need to handle XML documents in Go then check out 
https://github.com/twpayne/go-xmlstruct.

Re: [go-nuts] Re: Retrieve Path Parameters using inbuild http/Net package

[Stéphane Jeandeaux]

Hi,

Path parameters: http://
/path_parameter_1/path_parameter_2/?query_param1=...
The default library does not handle path parameters.

If you don't want to use an external library, you can implement your own
parsing by using url.EscapedPath.

[go-nuts] Re: Retrieve Path Parameters using inbuild http/Net package

[Peter Galbavy]

If you look in the http.Request passed to your handler, there is a URL 
field - use the net/url package to pull this out:

https://pkg.go.dev/net/url#URL
