[Bug]: uboot-patch preview is empty while it is not

[ig3]

What happened?

I am attempting to create a patch for u-boot with command $ ./compile.sh nanopi-r2s-plus uboot-patch DEBUG=yes, with 'userpatches/config-nanopi-r2s-plus.conf':

BOARD=nanopi-r2s-plus
BRANCH=current
BUILD_DESKTOP=no
BUILD_MINIMAL=yes
KERNEL_BTF=no
KERNEL_CONFIGURE=no
RELEASE=bookworm

The compile script runs until it prompts me to make my changes and press ENTER.

In another window, I added a new file in configs with ownership and permissions consistent with existing files (i.e. owned by root.root and rw-rw-r--).

I pressed ENTER in the window running compile.sh.

The script produced output that appears to indicate an empty patch file:

Are you happy with the diff above? Type 'y' or 'yes' to accept, 'stop' to stop patching, anything else to keep patching: stop

So I stopped (i.e. I entered 'stop'). Then I checked to confirm nothing had been produced in the output/patches directory.

What I expected is that a patch file would be produced for the creation of the config file I had created.

In previous attempts I created other files. I have not attempted to change any existing files because for the change I am trying to implement I don't need to change existing files.

How to reproduce?

Check out armbian/build branch main, commit 533fc7d (Feb 20 2025 - so reasonably recent)

Run the 'uboot-patch' command via compile.sh and add a file in the relevant u-boot config directory.

Alright, there seems to be a cosmetic bug. New files aren't shown for whatever reason in the patchfile preview. However if you press y to finish up patching the patchfile in the output folder looks just fine.

I hadn't tried accepting the patch. Having done so, I confirm - a patch file is produced with the content I was expecting.

Thanks for the quick response.
