Re: How does apt-get construt package uri?

Thanks Rob.
Now, if all the three current distributions are in the same pool, it must be possible that the same package has three versions co-existing in the same directory, and only Packages.gz from different distribution can tell apt-get which version to pick up?

Thanks to Eduardo Pereira Habkost's answer to the previous question - it works beautifully.

Here is a harder question (in my opinion, anyway): given a http/ftp line in sources.list, what's apt's algorithm for retrieve the list of packages. For example, deb http://http.us.debian.org/debian/ testing main non-free contrib

will produce such an output from apt-get:
 Get:1 http://http.us.debian.org testing/main Packages [2036kB]

So exactly what uri was constructed out of it? My browser says http://http.us.debian.org/testing/main doesn't exist. By the way, apt-get's manpage is very unclear in this aspects.

The line deb http://http.us.debian.org/debian/ testing main non-free contrib
will tell apt to go and get the packages file (which lists info about
each package) from http://http.us.debian.org/debian/dists/testing/main/binary-<arch>/

The actual packages are now stored in the `pool'.  That means that all
the packages for all three current distributions (woody, sarge and sid)
are in one big blob, in <first bit>/pool/.

So, in conclusion:
Packages.gz lives in
<first bit>/dists/<distribution>/<section>/binary-<arch>/
and packages live in
<first bit>/pool/<section>/<you can figure the rest out>
