Tips

If happens often that we commit changes and then we realize that we forgot to regenerate APKBUILD checksums. This is noticed by Travis (example) but you might want to avoid it.

You can install the following git hook that is run every time before you commit.

Copy the following code to .git/hooks/pre-commit inside your pmbootstrap repository:

#!/bin/bash
#
# PostmarketOS pre-commit hook
# Checks for bad checksums

./test/check_checksums.py

Now this is what happens when you forgot to regenerate checksums for some aport and try to commit

$ git commit -a
Checking device-qemu-aarch64 for correct checksums
[13:45:23] (native) generate checksums for device-qemu-aarch64

** The checksums are not correct

After that, simply do git commit -a --amend -n (-n is necessary so that this time the hook is not triggered).
