Subject Re: SHA-1 collision in repository?
Date Sun, 04 Mar 2018 10:31:24 GMT
How can I dump out the two things that Subversion thinks have the same
SHA-1 checksum but don't match?  This seems to be rather difficult to do.

That said, it's far more likely that there's a bug in Subversion than that
we randomly collided SHA-1.
