No prompt for SSH passphrase

[json2d]

When using an SSH key with a passphrase I don't receive a prompt for that passphrase when pushing/pulling, simply a Permission Denied message.

Thanks for raising this!

There are numerous places where Git requests a passphrase / username / password from the user, some of which cannot be intercepted as the prompt is not sent over stdout or stderr of the Git process (which is all the extension, and Node.js in general, can monitor), or using an external authentication system. This appears to the case in your situation, as you’ve said the error dialog only contains “Permission Denied”, and not the text prompting the entry of a passphrase (which would occur if it had of been requested on stdout or stderr of the Git command process).

Git Graph does already integrate with askpass authentication, which is used by Git for several username & password prompts, however askpass mustn’t be used in the situation you have.

Can you please confirm whether or not you’re able to use the Visual Studio Code push/pull status bar button? (I think it should also give you the same / similar error message as Git Graph does, as I just don’t think it’s possible to intercept the passphrase request to display a prompt in the UI)

I managed to produce a situation where the extension displays a "Permission Denied" error message due to an SSH passphrase not being entered (as there is no prompt in the UI). I assume this is the same as what you have, as you haven't provided any further detail / necessary information, or answered my previous question. (Please use the appropriate provided issue template in the future, as I took the time to create it specifically for these situations.)

When I checked the behaviour of Visual Studio Code's "Push/Pull" / "Synchronise Changes" Status Bar button, it displays the same "Permission Denied" error as the extension does. This indicates to me that Microsoft has reached the same conclusion as I did, that it is not possible in your situation to prompt the user for an SSH passphrase (at least from within Node.js). I'll close this issue for now as all indications suggest that it's not fixable within Git Graph.

If the extension was handling your situation any worse than Visual Studio Code itself, I would have immediately addressed it. However from everything I can see, the extension behaves identically to Visual Studio Code as they are both facing the same integration limitations with git.

Note to others reading this in the future: Please let me know if you're aware of a method to intercept such passphrase prompts, as it would definitely be best to make passphrase prompts visible to the user through the UI.

I believe you're right and the issue I was facing is the same when using the VSCode push/pull button. Thanks for looking into it.

I am using Git Graph on Windows with a remote repository (Raspberry PI) and it does ask for Github username/password. My issue is that it doesn't remember them and I have to keep typing the same credentials over and over again.

I have decided to push a commit, I am just using VS Code default push which does not ask for the password every time. It does remember the credentials.

My question... is there a way to get Git Graph to match VS Code and remember the credentials?

So the answer is that VSC can't provide a passphrase? That seems very odd. :(

Just add those keys bellow to your environment:

DISPLAY=needs-to-be-defined
SSH_ASKPASS=/mingw64/libexec/git-core/git-gui--askpass
