Except it’s not true at all. That data is all still there if you want it to exist and it’s not a real differentiator between Mercurial and git because Mercurial has the ability to do the same thing. Never mind the fact that “lose” your history makes it sound accidental instead of on purpose. It’s like saying that ``rm foo.txt`` will “lose” the data in foo.txt. So either it was a misunderstanding in which case I wanted to point out that those operations don’t magically lose information or it’s a purposely FUDish statement in which case I want to point out that the statement is inaccurate. The only thing that is true is that git users are more likely to use the ability to rewrite history than Mercurial users are, but you’ll typically find that people generally don’t do this on public branches, only on private branches. Which again doesn’t make much sense in this context since generally currently the way people are using Mercurial with CPython you’re using patches to transfer the changes from the contributor to the committer so you’re “losing” that history regardless. --- Donald Stufft PGP: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
