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

Enabling this backend is achieved by adding the libarchive qmake configuration value:

qmake CONFIG+=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)
