[go-nuts] Re: Is there a way to use the pakckages under vendor folder and from module cache?
Thanks for the suggestion.
I think the replace method works, but it is some tedious.
I need to add a "go.mod" file for each of the subfolders under "oldvendor",
and add a line in the "go.mod" of the main module.
But it looks this is the only way which works currently.
It would be great if there is a simpler way to support both
always-on vendor and cached vendor at the same time.

Re: [go-nuts] Pointer to the loop variable
Then turn vo into a Vertex variable, not a pointer
var vp Vertex = Vertex{}
...
if v.X == 3 {
vp = v
}
….
This time vp will be a copy of v,
Maybe you have to give some known values and exceptional case for your
domain, I mean, vp Vertex = { -1, -1} or any values your are
positive does not exists because maybe {0,0} is good data.

Re: [go-nuts] sqlserver error "TLS Handshake failed: x509: certificate signed by unknown authority"
You're missing the CA Root certificates for whatever linux distribution is
running your application. For example, I use Alpine linux as my Docker base
image for my Go services, and I must install the certificates like this via
the Dockerfile:
RUN apk update && apk add ca-certificates
Find the correct way to do that in your Docker base image.

[go-nuts] Re: Pointer to the loop variable
vp is taking the address of v, so when the loop ends, v is the last element
in the slide and therefore *vp is {0,0}
Add a break to the condition when you assign vp, say
if v.X == 3 {
vp =
break
}

[go-nuts] Pointer to the loop variable
I'm experiencing a weird problem with my program and finally nail it down
to what exactly went wrong, so that I can write a minimum program to
duplicate it. See the following program:
package main
import (
"fmt"
)
type Vertex struct {
X int
Y int
}
func main() {
vs := []Vertex{
Vertex{1, 2}, // has type Vertex
Vertex{X: 3}, // Y:0 is implicit
Vertex{}, // X:0 and Y:0
}
fmt.Printf("Vertex Slice %+v\n", vs)
var vp *Vertex = nil
for _, v := range vs {
if v.X == 3 {
vp =
}
}
fmt.Printf("Found: %+v\n", vp)
}
https://play.golang.org/p/R645C5plojx
I was expecting that the found Vertex is "v.X == 3", however the result is
not.
- what exactly is causing the problem?
- how to fix it so that I got what I was looking for?
Again, the snip is at

[go-nuts] Re: Is there a way to use the pakckages under vendor folder and from module cache?
Hello T L,
I think I might not fully understand the exact scenario, but one thing some
people have done when they have something in their vendor directory that
they can't otherwise find anywhere else (e.g., perhaps because it is
modified, or maybe the only copy of a now-missing dependency is in your
vendor directory) is to rename the vendor directory to something else
("oldvendor", or whatever name makes sense), and then set 'replace'
directives in the main project's go.mod file to point into the "oldvendor"
directory for whatever pieces from there are needed.
For example, something like:
require github.com/some/dependency v0.0.0
replace github.com/some/dependency =>
./oldvendor/github.com/some/dependency
I think that would allow you to pick and choose what you want from your old
vendor directory.
In terms of your other question, I think -mod=vendor is currently all or
nothing. There is a proposal to perhaps one day support partial vendoring,
but that is not in the current software.
Regards,
thepudds

Re: [go-nuts] Re: go mod dependency hell is real
Hello Darko, Rather than that 'replace' you found, a better solution is probably adding a 'require' for a more recent release of github.com/ugorji/go. Adding this to my go.mod worked for me in a simple test just now to resolve a similar error to what you reported: require github.com/ugorji/go v1.1.7 Using a 'require' for a recent version is better than the 'replace' you found for a couple reasons, including it is more forward looking, it ages out more gracefully, it helps anyone importing your project (avoiding the problem Sam W. just commented on), etc. Or, you likely could use a later version than v1.1.7. The v1.1.7 release of github.com/ugorji/go was specifically targeting resolving the error you reported, I believe.

The error is arguably not very helpful. Are you sure there is not another error
before the nil pointer exception? In any case, did you ensure that the .class
is included in the Android apk? An easy check is to try to call your method
from Java before trying from Go.

Re: [go-nuts] Re: go mod dependency hell is real
Note that replace directives are not transitive, so every single user of your library will need to do this. You can put it into your go.mod file to get your library building and get tests passing, but your users will still have to do this work as well so you'll probably want to document that they now have to jump through hoops to use your library. —Sam On Tue, Sep 10, 2019, at 13:10, Darko Luketic wrote: > The answer is apparently > https://github.com/gin-gonic/gin/issues/2039#issuecomment-527997733 > > > Add this to your go.mod file: `replace github.com/ugorji/go v1.1.4 > > => github.com/ugorji/go v0.0.0-20190204201341-e444a5086c43` > On Tuesday, September 10, 2019 at 2:48:25 PM UTC+2, Darko > Luketic wrote: > > What used to work pre go 1.13 now doesn't work anymore -- Sam Whited -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Re: Is there a way to use the pakckages under vendor folder and from module cache?
Or can go commands support a new special folder: dependencies. Its functionality is like the functionality of vendor folders, but to avoid being messed up with the packages under vendors. When running "go build -mod=vendor", the packages under the "dependencies" folder have higher look-up priorities than the packages under "vendor" folder.

[go-nuts] Re: Is there a way to use the pakckages under vendor folder and from module cache?
I mean "to use the pakckages under vendor folder and from module cache at the same time". I have one question, is it better to add a "go mod cache-locally" command to save the dependency modules in a "module-cache" folder in the current project, so that "go build -use-local-module-cache" can use the packages in the old "vendor" folder and the "module-cache" folder?

[go-nuts] Is there a way to use the pakckages under vendor folder and from module cache?
I maintain an private old Go project, which depends many many old packages. Before the module mode, I put all these dependency packages under the vendor folder. In the developing process, from time to time, I modified some of dependency packages. Meanwhile, I plan to migrate the project to modules mode and need to import some new module packages. I found I encountered an embarrassing situation. If I delete the vendor folder and run "go mod vendor" in modules mode to rebuild the vendor, the command will fail. One reason is some dependency packages disappeared. The other reason is many packages are updated and broke capabilities. And I don't want the new download to overwrite my local modifications for some dependency packages. So, is there a way to let me continue use the these old dependency packages and use some new modules based packages? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Distributing Go bindings: Go plugin vs Go archive vs Go shared package
Hello! I am trying to find out the best way to distribute Go bindings to a C library. I would like to avoid asking my users to install their target gcc because of cgo. So my idea is to avoid cgo by avoiding having my user compiling the bindings, by therefore distributing an already compiled package for every target GOOS and GOARCH. Some discussions on Go plugins I found are about this precise case but it is not supported on Windows so far. But I really don't get why isn't it possible to simply use the archive build mode `-buildmode archive` on the bindings, then include the resulting Go package archive in the repo, and simply use some go CLI option in order to use the correct archive for the target GOOS/GOARCH? I couldn't find out how to pass such option to the go compiler so far, so I was hoping for some help. Thanks for your help, Julio -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

Re: [go-nuts] Re: x/mobile: Samples for reverse binding in gomobile
Hello @elias,
I tried the following:
1. Created a java class :
package reversebinding;
public class RBinding {
public static String getStringFromJava() {
return "Hello from java !!";
}
}
2. Generated the .class file for this file.
3. Generated the android binding using gomobile tool and used
-classpath="Path to my .class file"
4. Binding is generated successfully.
*But when I used that generated (.aar) file in my android app and tried to
trigger the api it is crashing; *
