+test_description='git archive and git get-tar-commit-id test
This test covers the topics of file contents, commit date handling and
commit id embedding:
binary file (/bin/sh). Only paths shorter than 99 characters are
used.
- git tar-tree applies the commit date to every file in the archive it
+ git archive applies the commit date to every file in the archive it
creates. The test sets the commit date to a specific value and checks
if the tar archive contains that value.
- When giving git tar-tree a commit id (in contrast to a tree id) it
+ When giving git archive a commit id (in contrast to a tree id) it
embeds this commit id into the tar archive as a comment. The test
checks the ability of git get-tar-commit-id to figure it out from the
tar file.
