925ceccf | 6 | test_description='git archive and git get-tar-commit-id test |
d3d49c3d | 7 | |
5b860406 RS |
8 | This test covers the topics of file contents, commit date handling and |
9 | commit id embedding: | |
d3d49c3d RS |
10 | |
11 | The contents of the repository is compared to the extracted tar | |
12 | archive. The repository contains simple text files, symlinks and a | |
3dff5379 | 13 | binary file (/bin/sh). Only paths shorter than 99 characters are |
5b860406 | 14 | used. |
d3d49c3d | 15 | |
925ceccf | 16 | git archive applies the commit date to every file in the archive it |
d3d49c3d RS |
17 | creates. The test sets the commit date to a specific value and checks |
18 | if the tar archive contains that value. | |
19 | ||
925ceccf | 20 | When giving git archive a commit id (in contrast to a tree id) it |
d3d49c3d | 21 | embeds this commit id into the tar archive as a comment. The test |
5be60078 | 22 | checks the ability of git get-tar-commit-id to figure it out from the |
d3d49c3d RS |
23 | tar file. |
