Git clone causes an "SSL error: syscall failure:" with a specific repo

We are going to have to dump this library for this issue and move to using the cli instead. I figured I'd report this issue so maybe in the future someone can get around to fixing it. The issues has been reported before and have been open for over 4 years.

With a specific private repo, this error happens only on Alpine Linux in a container running as an ACA Job in Azure.
Authentication is being used (Personal Access Token) with the user of "default"

"[Message] SSL error: syscall failure: "

No other logging or error message.

Reproduction steps

This is extremely difficult to reproduce. I don't even know what it is about this specific repo that is causing the problem as other, repos owned by the same company using the same token, clone fine.

If I run locally in docker desktop, it does not crash. Everything else being equal.

I see others have reported the same issue and the bug has been open for years.

https://github.com/libgit2/libgit2sharp/issues/1262

Running the same user/token and URL from the cli git client works without issues.

git clone https:{user}:{token}@github.com/path/to/repo

I'm doing some digging to see if I can get more info about why it's happening.

I was able to get a detailed stacktrace from the service.

        [Exception]: [07/31/2024 23:56:31]: (/_/LibGit2Sharp/Core/Ensure.cs):(154)
        [Exception]: [07/31/2024 23:56:31]: (/_/LibGit2Sharp/Core/Ensure.cs):(172)

at LibGit2Sharp.Repository.Clone(String sourceUrl, String workdirPath, CloneOptions options) in //LibGit2Sharp/Repository.cs:line 824

Here is some feedback. The logging isn't very good in this function that's checking the response code from the code repository. If we could see the code that is being returned (and it doesn't seem to the HTTP OK) then we would have a better understanding about what the issue is.

This morning (8/1/2024) I implemented a cli version of git and it had no issues cloning from the ACA Job on the specific repo.

Expected behavior

The repo clones

Actual behavior

The library crashes

Bắt đầu với đường dẫn clone bị lỗi trong Core/Proxy.cs:278 và Repository.cs:824, sau đó kiểm tra các bước kiểm tra lỗi trong Core/Ensure.cs:154 và :172. Nếu có thể, hãy tái hiện lỗi trên Alpine Linux với .NET 8 bằng cách sử dụng repository riêng tư và cấu hình xác thực đã được báo cáo. Hoàn thành khi xác định được nguyên nhân và khiến việc clone thành công, hoặc báo cáo một lỗi có tính hành động cao hơn.
