go get on private gitlab repository fails with "no secure protocol found for repository" msg

[grecinto]

Use-case:

• migrated repository(ies) from GitHub.com to private gitlab repository(ies)
• setup HTTPs (via a reverse proxy that maps to HTTP) on the endpoint for use w/ git and go build tools
• use of "replace" statement in go.mod file to repoint to gitlab repo

Problem: gitlab repositories are suffixed with ".git", and since "go get" (or "go mod tidy") is truncating the .git part under this use-case (replace statement), it fails discovery phase

Example, a go.mod having "replace" statement to repoint to new repository location in "gitlab" such as:
replace ( github.com/abc/mdx v1.1.1 => foobar.com/abc/mdx.git v1.1.1 )

"git clone .." command works on this HTTPs Gitlab endpoint.
"go get -x" on the folder having this go.mod fails with the following steps printed out:
$ go get -x
cd /home/grecinto/go/pkg/mod
git ls-remote https://foobar.com/abc/mdx
cd /home/grecinto/go/pkg/mod
git ls-remote git+ssh://foobar.com/abc/mdx

Observation: as mentioned above, "go get" truncates the .git suffix thus, discovery fails.

Impact: Prevents continuity of the migrated to Gitlab private repositories and forces update of the go.mod and golang .go files to use the new gitlab full URL in import statements, a very exhaustive refactor work & forces code to Segway farther from the github.com repositories. Can't use just the "replace" statement to repoint and leave the code as is. What it(replace) is meant for.

it seems quite clear is misconfiguration on your end. please use one of the forums for troubleshooting your setup, the issue tracker is not the appropriate place to do it.

More info, I found out that the "go get" (or go mod tidy in this respect) is truncating the .git suffix when it tries to communicate to the "HTTPs" remote endpoint as it tries to discover and download the module(s).

Running "go get -x" to print out each step command/URL shows this:

$ go get -x
cd /home/grecinto/go/pkg/mod
git ls-remote https://foobar.com/abc/mdx
cd /home/grecinto/go/pkg/mod
git ls-remote git+ssh://foobar.com/abc/mdx

** I am ready to open an issue on this .git suffix being truncated (after next few hrs or tomorrow morning). Because it, the ".git" suffix, should be taken as is.
Here is the problematic line/step where .git suffix was being truncated:

git ls-remote https://foobar.com/abc/mdx

This should be:

git ls-remote https://foobar.com/abc/mdx.git

as specified in go.mod, from the "replace statement" like this:

replace (
	github.com/abc/mdx v1.1.1 => foobar.com/abc/mdx.git v1.1.1
)

gitlab works without the .git suffixes (example https://gitlab.com/gitlab-org/gitlab/-/issues/29629). if you have problems, it's because of other reasons.

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

That thread in your shared link discusses "git clone" which I also specified works. "go get" or "go mod tidy" is the one not working, discussed by this bug report. I am re-opening the case.

go invokes git, git operates on the repo, and git + gitlab works without the .git suffix.

[grecinto]

go invokes git, git operates on the repo, and git + gitlab works without the .git suffix.

Not true, here is the output of running "go get -x" (prints out each step):

$ go get -x
cd /home/grecinto/go/pkg/mod
git ls-remote https://foobar.com/abc/mdx
cd /home/grecinto/go/pkg/mod
git ls-remote git+ssh://foobar.com/abc/mdx

Obviously, the line: git ls-remote https://foobar.com/abc/mdx
is showing that the "go get" truncates the .git suffix. it should be issuing this cmd instead:

git ls-remote https://foobar.com/abc/mdx.git

AND running git commands on URLs w/ truncated .git suffix vs gitlab repo is NOT working.

[grecinto]

Adding this link to provide evidence from other experts that the ".git" suffix is forcing "us" to reimplement the go.mod and .go code files "import statement", and that git + gitlab does NOT work without the ".git" suffix:

Observe the operation log for go operating on a gitlab repo,
both clones succeed whether or not .git is specified in the url go / git uses.

You are feeding it with URL & a public gitlab repo, that is a different use-case. Use my use-case, where you issue "go get -x" so you take go.mod (of current folder) contents and let go get compose the URLs in discovery. Also, I specified private gitlab repo, not public. The public repo approach, it went to "proxy go org" way and can download from there, that is a different use-case than "private" gitlab repo.

The go.mod should contain "replace" statement such as:
replace (github.com/abc/mdx v1.1.1 => gitlabce.com/abc/mdx.git v1.1.1)

And in gitlabce.com, you have a repo abc/mdx.git with (release) tag v1.1.1.

Go only operates on module paths, not urls.

[grecinto]

I am using go 1.23.5 version and I meant module "paths" in this context. I just used the word URL, but technically, a path/URI. Does that work in go 1.23.5? Because 1.24, the one you are using is still not "out", or NOT downloadable from public download sites.

[seankhliao]

Nothing has changed wrt to invoking mapping module paths for git repos for years.
If you have problems, it's almost certainly misconfiguration on your side, as evidenced by the many projects available on gitlab.

as before, please take troubleshooting your personal setup to a forum.
