-test_description='resilience to pack corruptions with redundant objects'
-. ./test-lib.sh
-
-# Note: the test objects are created with knowledge of their pack encoding
-# to ensure good code path coverage, and to facilitate direct alteration
-# later on.  The assumed characteristics are:
-#
-# 1) blob_2 is a delta with blob_1 for base and blob_3 is a delta with blob2
-#    for base, such that blob_3 delta depth is 2;
-#
-# 2) the bulk of object data is uncompressible so the text part remains
-#    visible;
-#
-# 3) object header is always 2 bytes.
