Add a file with a long name to the test archive in order to check entries with pax extended headers. Also add a check for tar versions that doen't understand this format. Those versions should extract the headers as a regular files. Add code to check_tar() to interpret the path header if present, so that our tests work even with those tar versions. It's important to use the fallback code only if needed to still be able to detect git archive errorously creating pax headers as regular file entries (with a suitable tar version, of course). The archive used to check for pax header support in tar was generated using GNU tar 1.26 and its option --format=pax. Tested successfully on NetBSD 6.1, which has a tar version lacking pax header support. Signed-off-by: René Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

test_description='git tar-tree 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 tar-tree 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 tar-tree 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.
