Subject: dact: replacing tar

Hello again, some more thoughts for you to consider.

.tar.gz really sucks, im writting some code that works on files inside a
.tar.gz in busybox and its a real hassle, i have to fork and uncompress
in a child process and feed the uncompressed data back the main function
that can untar it.

The problem stems from the fact that the tar file is compressed rather
than the individual files, if people did .gz.tar that it would be easy
to work on individual files within the archive, but it wouldnt get as
good compression due to the probably reduced block size (if the files
are small).

The loss in compression from appending files compressed with dact
probably wouldnt be as bad as .tar.gz as dact can take advantage of
different compresion methods for small files.

The real reason i would like to see this could also tie in well with
your url idea that you have been working on.

If dact something like an index file that had a list of filenames, their
offset and compressed size, then it would be possible to download and
unpack only one file within an archive.

e.g. linux-2.4.4.tar.gz is about 20MB, say i want to look at the
./README file, to do so i have to download the entire 20MB, uncompress
it, untar it, then access README.

In would be good to start the download of linux-2.4.4.dct and read
untill the end of the index section of the file and close the connection
(or have the index file seperate), then with the index file i would know
where abouts in the linux-2.4.4.dct the ./README file starts, so we
could open a connection and start resuming the download from the offset
of the ./README, rather than from the start of the file.

You have mentioned you had ideas for combining multiple compressed
files, so hopefully something like this could be worked into your plans.
