How to efficiently generating the diffstat?

Hi,

I need some help to efficiently generating the diffstat. I would like to get the number of lines added and deleted from one commit to another, like the following command does:

git log --stat

I wrote the following code, but it is pretty slow.

for raw_parent in self.__raw_commit.parents:
    diff = self.__raw_commit.tree.diff_to_tree(raw_parent.tree)
    self._stats.insertions += diff.stats.insertions
    self._stats.deletions += diff.stats.deletions
    self._stats.files_changed += diff.stats.files_changed

Do you know a better way to capture this information?

Best regards,

Inizia con il ciclo Python su self.__raw_commit.parents e con gli entry point tree.diff_to_tree e diff.stats, quindi confrontane l’obiettivo con git log --stat. Determina se pygit2 o libgit2 espone un modo più efficiente per ottenere inserimenti, eliminazioni e file modificati; il lavoro è completato quando l’approccio è stato identificato e produce valori diffstat equivalenti.
