• Any other interesting things about your environment that might be related
  to the issue you're seeing?

NO

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Bash

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

$ echo "test" > text.txt
$ git add -N text.txt
$ git gui
I then try to stage the hunk or a line in the test.txt file in git gui using the right click menu. 

• What did you expect to occur after running these commands?

I expected that I could add a hunk or line in the new file, instead nothing happens after clicking one of these options in the context menu. To make sure you understand me, I added a screenshot of the context menu in question:

• What actually happened instead?

The hunk can not be added through the GUI. (nothing happens after clicking this option in the right click menu) Also note that the terminal prints the following errors as well while starting git gui:

error: no icon for .vpane.files.workdir.list state={A} text.txt
error: no desc for state={AA} text.txt

I downgraded to 2.27.0 to validate if the recent upgrade broke this. In 2.27.0 everything works fine! No error is printed when starting git gui and i can add a hunk or line using the right click menu.

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

I can replicate this problems in multiple repositories.

This might be related to https://lore.kernel.org/git/20200808074959.35943-1-ray@ameretat.dev/. Would you be able to build Git from scratch? If so, you could test whether merging the rp/ita-diff-modefix branch from https://github.com/gitster/git fixes the issue (and in that case, you could open a PR and we'd get that fix really quickly).

[pascalmuller]

@dscho I have never built Git before, but I decided to give it a shot.

Unfortunately, it does not seem to solve the bug described here.

Just to be certain I did this correctly; these are the steps I've done.

** INSTALL GIT SDK
$ sdk cd git
$ git checkout -b test
$ git fetch https://github.com/gitster/git.git rp/ita-diff-modefix
$ git merge FETCH_HEAD
$ make install
** RUN STEPS TO REPRODUCE in another directory, as outlined in ticket

To be certain I was using the version of Git I built, I added an extra line of output to git status and repeated the steps. As I saw my change, I am quite certain the steps above have worked; but the merge of rp/ita-diff-modefix did not solve the issue.

[dscho]

Thanks for testing! And: bummer that it did not fix it. Let me give it a whirl.

[dscho]

Oh my. I totally wrote the wrong branch name: rp/apply-cached-with-i-t-a is the one I actually meant.

But even then, things don't work, there need to be a couple fixes in Git GUI's code itself.

[dscho]

I have a tentative fix that I just submitted to the Git mailing list for review: gitgitgadget#699

[pascalmuller]

Happy I could help a little bit; thanks for looking into it so quickly!

Hope it'll be fixed soon.

[dscho]

@pascalmuller As I merged this, there will hopefully soon be a new snapshot for you to test. It would be good if you could verify that it works (ideally within the next 24h, i.e. before v2.29.0 is due).

[dscho]

(FWIW the installer and friends are being built right now and this Release Pipeline should then automatically upload the snapshot, in case you are interested to see the progress.)
