libarchive Decompression Backend

This backend utilizes the libarchive library to support a wide variety of compression formats.

This backend is currently only supported on the Linux platform.

Using

Enable this backend by setting the DECOMPRESSION_BACKEND CMake option:

cmake -B build -DDECOMPRESSION_BACKEND=libarchive

Upon success, the application can be built as normal.

Limitations

• libarchive has a stream-based architecture that does not (currently) offer random access. In practice, this means that you can only seek forward and would have to re-open an archive to read an entry before the current position. This doesn't seem to have a huge performance hit and can be mitigated by creating properly sorted archives.
• 7z decompression is slow (but seems to be slightly faster than unarr)
