0837348049 Follow redirects when checking for the existence of MANIFEST.bz2
If we don't follow redirects, we might think that MANIFEST.bz2 exists
just because the HEAD request succeeds on the redirector URI.

f8e609c341 * nix-pull: update the Nix manifest cache if necessary. Also, don't
read the manifest just to check the version and print the number of
  paths.  This makes nix-pull very fast for the cached cache (speeding
  up nixos-rebuild without the ‘--no-pull’ or ‘--fast’ options).

d7d7910ba4 * Don't decompress the manifests in /nix/var/nix/manifest. This saves
disk space, and, since they're typically only decompressed once (to
  fill the manifest cache), doesn't make things slower.

3cbf680f5d * configure: detect whether DBD::SQLite is present. If necessary the
location to DBI and DBD::SQLite can be passed with --with-dbi and
  --with-dbd-sqlite.

1e7e4f21ba * Remove the localPaths feature in manifests since it's no longer used
and redundant anyway.

7ca9972636 * When doing a nix-pull, remove old manifests downloaded from the same
URL.  This prevents lots of old cruft accumulating in
  /nix/var/nix/manifests.

3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.

9e975458b4 * Get rid of the substitutes database table (NIX-47). Instead, if we
need any info on substitutable paths, we just call the substituters
  (such as download-using-manifests.pl) directly.  This means that
  it's no longer necessary for nix-pull to register substitutes or for
  nix-channel to clear them, which makes those operations much faster
  (NIX-95).  Also, we don't have to worry about keeping nix-pull
  manifests (in /nix/var/nix/manifests) and the database in sync with
  each other.

  The downside is that there is some overhead in calling an external
  program to get the substitutes info.  For instance, "nix-env -qas"
  takes a bit longer.

  Abolishing the substitutes table also makes the logic in
  local-store.cc simpler, as we don't need to store info for invalid
  paths.  On the downside, you cannot do things like "nix-store -qR"
  on a substitutable but invalid path (but nobody did that anyway).

* Never catch interrupts (the Interrupted exception).

4695f4edd6 * nix-pull: support bzipped manifests: when doing a nix-pull on $url,
try $url.bz2 first.

c5e934dcc9 * nix-pull: using nix-prefetch-url (so that we get caching for free),
and store the manifests in the Nix store.  (So now
  /nix/var/nix/manifests/ just contains symlinks to the store and is
  searched for GC roots.)

f881f7a017 * nix-prefetch-url: support caching. If the environment variable
NIX_DOWNLOAD_CACHE is set, then nix-prefetch-url will store the hash
  and timestamp of downloaded files in the directory
  $NIX_DOWNLOAD_CACHE.  This allows it to figure out if the file is
  still in the Nix store.

bae75ca5a1 * New kind of manifest object: "localPath", which denotes that a store
path can be created by copying it from another location in the file
  system.  This is useful in the NixOS installation.

d43565c3e8 * In `nix-channel --update', skip manifests that assume a Nix store at
a different location than the user's.  This makes channels usable as
  a source deployment mechanism for people who install Nix under
  non-standard prefixes.  (NIX-57)

95304172a5 * Don't use IPC::Open2, it has a subtle race bug on Mac OS X 10.4. If
the parent runs before the child, it closes some pipe file
  descriptors which causes the child to fail due to a bad file
  descriptor.  So we just use the normal open() function instead.
  
  This fixes NIX-14 (intermittent nix-pull failures).

98df735b51 * Propagate the deriver of a path through the substitute mechanism.
* Removed some dead code (successor stuff) from nix-push.
* Updated terminology in the tests (store expr -> drv path).
* Check that the deriver is set properly in the tests.

48ebe4527e * Better error reporting in readmanifest.
* Use force flag in `mv' to prevent silly interactive questions (this
  happens with shared Nix stores).

invariant by registering references through the manifest.

77970f8daf * Remove `prebuilts.conf' file, it's not like anybody was using it.
* Add /nix/var/nix/manifests directory.

862f4c154e * Patch deployment. `download.pl' (intended to be used in the
substitute mechanism) creates a store path by downloading full NAR
  archives and/or patches specified in the available manifests.

  Any combination of present paths, full downloads, and patches can be
  used to construct the target path.  In particular, patches can be
  chained in sequence; and full NAR archives of the target path can be
  omitted (i.e., patch-only deployment is possible).  A shortest path
  algorithm is used to find the smallest set of files to be downloaded
  (the edge weights are currently file sizes, but one can imagine
  taking the network speed to the various source into account).

  Patches are binary deltas between two store paths.  To be precise,
  they are the output of the `bsdiff' program applied to the NAR
  archives obtained by dumping (`nix-store --dump') the two store
  paths.  The advantage of diff'ing NAR archives (and not, say, doing
  file-by-file diffs) is that file renames/moves are handled
  automatically.  The disadvantage is that we cannot optimise creation
  of unchanged files (by hard-linking).
