[svn] If we can't figure out what the file is by mimetype, try using the file
command to figure out what it is instead.
This completely changes the program structure because now we might try to
use several extractors on a particular file before giving up. I haven't
really done the refactoring that would be appropriate for a change this
fundamental. I'd like to do that before the next release.
We should always extract to a new, temporary directory (except maybe in the straight decompression case), and then move that directory based on what we actually want. This has several advantages: * Much easier to check whether or not the archive is a bomb (O(1) operation) * Can find other archives more reliably * Can set up a direct pipe from a decompressed to the unarchiver, since we're not interested in reading it multiple times anymore. * All this should mean x is faster, too. Things which I have a use case/anti-use case for: * CAB extraction. * Use file to detect the archive type. * Support lzma compression (http://tukaani.org/lzma/download) * Support pisi packages (http://paketler.pardus.org.tr/pardus-2007/) * Steal ideas from <http://martin.ankerl.com/files/e>. * Figure out what the deal is with strerror. (done?) * Better error messages (file doesn't exist, isn't readable, etc.) * Consistently raise and handle exceptions. Things that are generally good: * Better tests. * Better error messages. Things I think might be good but can't prove: * Take URLs as arguments. * Consider having options about whether or not to make sane directories, have tarbomb protection, etc. * Use zipfile instead of the zip commands. * Processing from stdin. * Extracting control.tar.gz from deb files. * shar support.
