Move from read_gz to the pipe()+fork() method. open_transformer(), common code for pipe+fork. Function pointer for read() no longer needed. Allow inflate to be initialised with a specified buffer size to avoid over-reading. Reset static variables in inflate_get_next_window to fix a bug where only the first file in a .zip would be be extracted. 2003-11-15 23:19:05 +00:00
update seamless uncompression code This change makes "tar tf hello_world.txz" work without adding special-casing for ".txz" extension.
