Subject: t/lib-diff-alternative: abstract away SHA-1-specific constants
X-Git-Tag: v2.18.0-rc0~3^2~5
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/d29d5001e9614871e05410362b20e1f0a76157a6?hp=--cc

t/lib-diff-alternative: abstract away SHA-1-specific constants

Adjust the test code so that it computes variables for blobs instead of
using hard-coded hashes.  This makes t4033 and t4050 (the patience and
histogram tests) pass.
