These options may not be provided +by non-GNU tar nor even by slightly older GNU tar versions which ship on +many systems. + +An example of the latter case is the --zstd option. This was added in +GNU tar-1.32 (2019-02-23)¹. This version of tar is not provided by +CentOS/RHEL, in particular. In Debian, --zstd has been backported to +the tar-1.30 release. + +Avoid the requirement on any specific implementations or versions of tar +by piping decompressed output to tar. This is compatible with older GNU +tar releases as well as tar implementations from other vendors. (It may +also be a slight benefit that this more closely matches what the +snapshot creation code does.) + +¹ Technically, the --zstd option was first released in tar-1.31 + (2019-01-02), but this release was very short-lived and is no longer + listed on the GNU Tar release page. + +Signed-off-by: Todd Zullinger <tmz@pobox.com> +--- + tests/t0107-snapshot.sh | 8 ++++---- + 1 file changed, 4 insertions(+), 4 deletions(-) + +diff --git a/tests/t0107-snapshot.sh b/tests/t0107-snapshot.sh +index c164d3e..8ea95ce 100755 +--- a/tests/t0107-snapshot.sh ++++ b/tests/t0107-snapshot.sh +@@ -25,7 +25,7 @@ test_expect_success 'verify gzip format' ' + + test_expect_success 'untar' ' + rm -rf master && +- tar -xzf master.tar.gz ++ gzip -dc master.tar.gz | tar -xf - + ' + + test_expect_success 'count files' ' +@@ -67,7 +67,7 @@ test_expect_success LZIP 'verify lzip format' ' + + test_expect_success LZIP 'untar' ' + rm -rf master && +- tar --lzip -xf master.tar.lz ++ lzip -dc master.tar.lz | tar -xf - + ' + + test_expect_success LZIP 'count files' ' +@@ -109,7 +109,7 @@ test_expect_success XZ 'verify xz format' ' + + test_expect_success XZ 'untar' ' + rm -rf master && +- tar --xz -xf master.tar.xz ++ xz -dc master.tar.xz | tar -xf - + ' + + test_expect_success XZ 'count files' ' +@@ -151,7 +151,7 @@ test_expect_success ZSTD 'verify zstd format' ' + + test_expect_success ZSTD 'untar' ' + rm -rf master && +- tar --zstd -xf master.tar.zst ++ zstd -dc master.tar.zst | tar -xf - + ' + + test_expect_success ZSTD 'count files' ' |
