In archive_write_disk: If archive_write_header() fails to create the file, that's a failure and should return ARCHIVE_FAILED. Metadata restore failures still return ARCHIVE_WARN, because that's non-critical. Fix test_write_disk_secure test to verify the correct return code in one case; add test_write_disk_failures to do another very simple test of restore failure. This should fix cpio coredumping when it tries to restore to a write-protected directory. Thanks to: Giorgos Keramidas MFC after: 30 days
