TBZ2 - Empty Archive
The empty tar under bzip2. Its payload is 1024 identical bytes, which is the run-length case bzip2's block sorter treats specially, so this doubles as the smallest sane bzip2 stream to test a decoder against.

Testing contract
Expected to pass- Scenario
- Decompress the bzip2 stream, then list the tar inside it.
- Expected result
- The bzip2 layer decodes its single run-length block to exactly 1024 bytes of zeros and the tar listing reports 0 members with no error.
What is a .tbz2 file?
TBZ2 is a shorthand extension for a TAR archive compressed with bzip2, equivalent to .tar.bz2. The tar step bundles files and metadata, then bzip2 compresses the combined stream for a higher ratio. It is used for distributing larger source and data archives.
How to use this file
Use an example TBZ2 to test the decompress-then-untar pipeline with bzip2, and tools that recognize the abbreviated .tbz2 extension.
How to use this file for testing
“TBZ2 - Empty Archive” is a deterministic Novus Examples fixture for Conversion testing, Error handling, Compression testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Archive fixtures are documented down to their member list (shown on this page) and are deliberately safe — no zip bombs, executables, or hidden payloads. Test extractors against nested, unicode, empty, and encrypted variants.
