t5003: check if unzip supports symlinks
Only add a symlink to the repository if both the filesystem and unzip support symlinks. To check the latter, add a ZIP file containing a symlink, created like this with InfoZIP zip 3.0: $ echo sample text >textfile $ ln -s textfile symlink $ zip -y infozip-symlinks.zip textfile symlink If we can extract it successfully, we add a symlink to the test repository for git archive --format=zip, or otherwise skip that step. Users can see the skipped test and perhaps run it again with a different unzip version. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
