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.
