GPG signing is bent on WIndows

GPG signing is bent on WIndows

[Jeffrey Walton]

Several weeks ago I updated to the latest Git for Windows (when
prompted by the version check). At the time I noticed:

$ git commit -S -am "Fix unset MAKE variable in test scripts"
gpg: signing failed: No pinentry
gpg: signing failed: No pinentry
error: gpg failed to sign the data
fatal: failed to write commit object

I got to look at it today. On Windows:

$ cat ~/.gnupg/gpg-agent.conf
pinentry-program
/usr/local/MacGPG2/libexec/pinentry-mac.app/Contents/MacOS/pinentry-mac

Do you have this app on your system? That path looks like one for a mac 
pinentry program and won't work on Windows. There are several tutorials on the 
web that explain how to get GPG working on windows. I suggest starting there.  
Get so that you can sign normal files from the command line on Windows and then 
try again.

Git for Windows is partially based off of MSYS2, which upgraded GPG from
v1 to v2, and one of the consequences is that v2 handles interaction with
the user differently.

My guess is that you copied your config from a Mac, and the path is simply
incorrect. I would wager a bet that it starts working when you remove that
line with the incorrect path, as the default should work plenty fine for
you.

Ciao,
