| 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: |
| |
| The contents of the repository is compared to the extracted tar |
| archive. The repository contains simple text files, symlinks and a |
| binary file (/bin/sh). Only paths shorter than 99 characters are |
| used. |
| |
| 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 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. |
