- Extract a Tar - Tar Extractor
-
- Some performance measurements showed that zlib performed quite poorly
- in comparison to a forked gzip process. This tar extractor makes use
- of the fact that dup'd file descriptors have the same seek pointer
- and that gzip will not read past the end of a compressed stream,
- even if there is more data. We use the dup property to track extraction
- progress and the gzip feature to just feed gzip a fd in the middle
- of an AR file.
