/usr/bin/git calling git-credential-manager.exe via pipe hangs.

• Your Windows build number: Microsoft Windows [Version 10.0.16299.309]

In order to use git both in WSL and in Windows with the same auth credentials, I tried to install https://github.com/Microsoft/Git-Credential-Manager-for-Windows and then point both gits to it.

The way this works is that one adds this to ~/.gitconfig:

[credential]
        helper = manager

Git will then communicate with git-credential-$HELPER via pipe. In my $PATH in WSL I have a link to git-credential-manager.exe so that /usr/bin/git can execute it. When it does run it (say, when I do git push) it jugs hangs there.

As a workaround I've replaced the ~/bin/git-credential-manager -> /mnt/c/.../git-credential-manager.exe symlink with the following shell script:

#!/bin/sh
tee .git/creds | powershell.exe /c "Start-Process -Wait -FilePath 'C:\Program Files\Git\mingw64\libexec\git-core\git-credential-manager.exe' -NoNewWindow -ArgumentList $@ -RedirectStandardInput .git/creds"
rm -f .git/creds

This seems to work just fine (at the expense of temporarily keeping the credentials on disk).

I am at a loss as to why the pipe doesn't cross the interop. Help?

Due to the nature of the strace output, I'll send it over to the secure@ address.
