6 test_description='git tar-tree and git get-tar-commit-id test
8 This test covers the topics of file contents, commit date handling and
9 commit id embedding:
11 The contents of the repository is compared to the extracted tar
12 archive. The repository contains simple text files, symlinks and a
13 binary file (/bin/sh). Only paths shorter than 99 characters are
14 used.
16 git tar-tree applies the commit date to every file in the archive it
17 creates. The test sets the commit date to a specific value and checks
18 if the tar archive contains that value.
20 When giving git tar-tree a commit id (in contrast to a tree id) it
21 embeds this commit id into the tar archive as a comment. The test
22 checks the ability of git get-tar-commit-id to figure it out from the
23 tar file.
