Move tag to other commit

Question

While I can imagine to e.g. delete the tag via Reference.delete and then to recreate it anew (on the other commit), I wonder what the "official" way of moving a tag in pygit2 is.

Answer 1

The race-free way to change that a reference points to is by setting its target field.

ref.target = tag.id

will make sure it updates the reference, removing a possible race condition with a cleanup process.
