6 test_description='git archive and git get-tar-commit-id test
7
8 This test covers the topics of file contents, commit date handling and
9 commit id embedding:
10
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.
15
16 git archive 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.
19
20 When giving git archive 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.
