Example 18 with GzipCompressorOutputStream

use of org.apache.commons.compress.compressors.gzip.GzipCompressorOutputStream in project neo4j by neo4j.

the class Dumper method openArchiveOut.

private static ArchiveOutputStream openArchiveOut(Path archive) throws IOException {
    // StandardOpenOption.CREATE_NEW is important here because it atomically asserts that the file doesn't
    // exist as it is opened, avoiding a TOCTOU race condition which results in a security vulnerability. I
    // can't see a way to write a test to verify that we are using this option rather than just implementing
    // the check ourselves non-atomically.

    tarball.setLongFileMode(TarArchiveOutputStream.LONGFILE_POSIX);
