git.exe ignoring any input from keyboard

[rafis]

I'm running git pull:

>git pull
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)

I can't press nor Yes, nor No. Only Ctrl-C works. I have tried both MinTTY and Windows cmd.exe.

Git for Windows 2.5.3
Putty 0.65

Isn't it mentioned somewhere in the release notes that you need to connect via Putty first before you can connect from Git?

Yep, indeed. It is the second from top entry of the Known Issues:

• If configured to use Plink, you will have to connect with putty first and accept the host key.

It somehow doesn't work even with this simple exe instead of plink:

int main(int argc, char **argv)
{
    char line[32];
    char ch = getchar();
    line[0] = ch;
    line[1] = '\0';
    printf(line);
    return 0;
}

@KindDragon you might have more luck when prefixing the Git command with winpty (which is a command that emulates a Win32 Console while still really interacting with the MinTTY window).

[KindDragon]

I've tried run git fetch directly from MinTTY console, but no luck.
I don't know how ssh.exe works without that issue with Git for Windows, but even simple console app can't get console input when called from Git.

Maybe because of simple console app was compiled using MSVC(?)

As I asked: please try with winpty git fetch.

I don't know how ssh.exe works without that issue with Git for Windows, but even simple console app can't get console input when called from Git.

As I tried to explain, MinTTY does not use a real Win32 Console (and neither does ssh.exe, they both rely on the POSIX emulation of a tty provided by the MSYS2 runtime).

Maybe because of simple console app was compiled using MSVC(?)

Indeed. MSVC has no idea about MSYS2's runtime and its tty emulation.

So again, please try with winpty.

Same result
