#!/bin/sh # # Copyright (C) 2005 Rene Scharfe # 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.
