# [PATCH] t9300: use cmp instead of test_cmp to compare binary files 4 messages from 2014-09-12 to 2014-09-12. Participants: Johannes Sixt, Junio C Hamano, Thomas Braun. Thread: https://gitlist.dev/t/37546 ## Johannes Sixt, 2014-09-12 17:34 Subject: [PATCH] t9300: use cmp instead of test_cmp to compare binary files Message-ID: <54132E88.8050803@kdbg.org> URL: https://gitlist.dev/e/54132E88.8050803%40kdbg.org ``` test_cmp is intended to produce diff output for human consumption. The input in one instance in t9300-fast-import.sh are binary files, however. Use cmp to compare the files. This was noticed because on Windows we have a special implementation of test_cmp in pure bash code (to ignore differences due to intermittent CR in actual output), and bash runs into an infinite loop due to the binary nature of the input.

I did remember that there was talk about it, but missed that we actually implemented it.
