Commit 6aed945fe89f1295314b398bc61f7dd54f658293
2015-09-25T10:37:41
Fix binary diffs git expects an empty line after the binary data: literal X ...binary data... <empty_line> The last literal block of the generated patches were not containing the required empty line. Example: diff --git a/binary_file b/binary_file index 3f1b3f9098131cfecea4a50ff8afab349ea66d22..86e5c1008b5ce635d3e3fffa4434c5eccd8f00b6 100644 GIT binary patch literal 8 Pc${NM&PdElPvrst3ey5{ literal 6 Nc${NM%g@i}0ssZ|0lokL diff --git a/binary_file2 b/binary_file2 index 31be99be19470da4af5b28b21e27896a2f2f9ee2..86e5c1008b5ce635d3e3fffa4434c5eccd8f00b6 100644 GIT binary patch literal 8 Pc${NM&PdElPvrst3ey5{ literal 13 Sc${NMEKbZyOexL+Qd|HZV+4u- git apply of that diff results in: error: corrupt binary patch at line 9: diff --git a/binary_file2 b/binary_file2 fatal: patch with only garbage at line 10 The proper formating is: diff --git a/binary_file b/binary_file index 3f1b3f9098131cfecea4a50ff8afab349ea66d22..86e5c1008b5ce635d3e3fffa4434c5eccd8f00b6 100644 GIT binary patch literal 8 Pc${NM&PdElPvrst3ey5{ literal 6 Nc${NM%g@i}0ssZ|0lokL diff --git a/binary_file2 b/binary_file2 index 31be99be19470da4af5b28b21e27896a2f2f9ee2..86e5c1008b5ce635d3e3fffa4434c5eccd8f00b6 100644 GIT binary patch literal 8 Pc${NM&PdElPvrst3ey5{ literal 13 Sc${NMEKbZyOexL+Qd|HZV+4u-
