Commits are no longer gpg-signed in 2.9.0 when "commit.gpgsign" is enabled

Hey Git community,

since Version 2.9.0, the configuration option "commit.gpgsign" doesn't 
work as users would expect. By committing via 'git gui' (or usual 'git 
commit'  without further option), commits are not being auto-signed any 
longer, when "commit.gpgSign" configuration option is set. I also 
couldn't find a flag to "workaround" that situation in the GUI. To my 
understanding, I now have to pass the '-S' option to 'git commit' every 
time and GUI becomes "impractical to use". Surprisingly, nobody seems 
having noticed this behavioural change since the release of 2.9.

FYI: In the release log, there's a note stating, that this has been 
altered in the context of 'git commit-tree'. Maybe this interferes with 
"normal" behaviour.

Would be happy hearing from you soon. Thanks!

Cheers,
Nils

Hi Nils,

I just checked and I have commits made in 2.9 with this option set and I
don't seem to have your issue. Here's what I did:

    santiago at ~/test-signing ✔ git init
    Initialized empty Git repository in /home/santiago/test-signing/.git/
    santiago at ~/test-signing ✔ hub create
    Updating origin
    Enter passphrase for key '/home/santiago/.ssh/id_rsa':

    git version 2.9.0
    santiago at ~/test-signing ✔ 

You can check the github repository 

Do you have a mwe/.gitconfig so I can take a look at it? 

I wonder if this issue is similar to what happened in mutt, where gpg
doesn't show the password prompt using gpg-agent and it silently failed.

Thanks,
-Santiago.

Hi Santiago,

repeated your test here and actually found something interesting. When
committing via 'git gui', commits are not being gpg-signed, while firing
a 'git commit' shows the passphrase dialog and signs the commit correctly.

Here's what I did:

git init gpg-signing-test && cd gpg-signing-test
git config --local commit.gpgSign true
echo 'Commits in this repo must all GPG signed!' > aFile.txt
git gui --> add change and commit

Result: No dialog shown and not pgp-signed!

Now I went further:
vi aFile.txt --> Prepend a "# " as another change
git commit

Here the passphrase dialog showed up and the commit got correctly signed!

Side-Note: I also set "user. signingkey" in "global" Git configuration.

My local repo's config:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[commit]
    gpgSign = true
[gui]
    wmstate = normal
    geometry = 872x391+0+0 205 177

-- 

What you mean by wme? Is it the gpg-agent's config or something?

Hope that points in the right direction.

Cheers,
Nils

I have the feeling that this is an issue with your gpg configuration not
playing well with the gui. Do you know which pinentry program is being
used (e.g., type /usr/bin/pinentry).

Sorry, I meant a Minimum Working Example, although that'll be hard to
reproduce in this case. Your configuration seems to be proper.

Hope that points in the right direction.

I think that we can take further troubleshooting off-list. This doesn't
seem to be behavior with git (although we can come back with a bug
report if something is naturally-broken/could be improved)

Cheers!

"git gui" probably needs an update similar to what was discussed in this thread
