This is fewer lines of code, but more importantly, fixes a
bogus pointer offset. We are looking for "tar." in the
section, but later assume that the dot we found is at offset
9, not 3. This is a holdover from an earlier iteration of
767cf45 which called the section "tarfilter".
As a result, we could erroneously reject some filters with
dots in their name, as well as read uninitialized memory.

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.
