Eelco Dolstra 66c51dc215 * nix-store --dump-db / --load-db to dump/load the Nix DB.
* nix-store --register-validity: option to supply the content hash of
  each path.
* Removed compatibility with Nix <= 0.7 stores.

Eelco Dolstra 633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.

Eelco Dolstra c05783ad67 * nix-store --import: add a flag --require-signature. 2007-11-16 16:10:27 +00:00
Eelco Dolstra 14e47e9c2c * Doh. 2007-10-10 14:58:00 +00:00
Eelco Dolstra 315183f194 * nix-store --optimise: flag "--dry-run" to just query what the disk
savings would be.

Eelco Dolstra a8629de827 * New command `nix-store --optimise' to reduce Nix store disk space
usage by finding identical files in the store and hard-linking them
  to each other.  It typically reduces the size of the store by
  something like 25-35%.  This is what the optimise-store.pl script
  did, but the new command is faster and more correct (it's safe wrt
  garbage collection and concurrent builds).

Eelco Dolstra 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).

Eelco Dolstra 6d1a1191b0 * Support queryDeriver() in multi-user installations. 2007-06-12 16:53:44 +00:00
Eelco Dolstra 7f6161ab3a * Flush cout to show progress. 2007-02-21 23:08:55 +00:00
Eelco Dolstra 0db450024d * Export/import many paths in one go. 2007-02-21 23:00:31 +00:00
Eelco Dolstra 9da367b7d5 * `nix-store -qR' and friends: print the paths sorted topologically
under the references relation.  This is useful for commands that
  want to copy paths to another Nix store in the right order.

Eelco Dolstra 881feb9698 * Flag --print-invalid' in nix-store --check-validity' to print out
which paths specified on the command line are invalid (i.e., don't
  barf when encountering an invalid path, just print it).  This is
  useful for build-remote.pl to figure out which paths need to be
  copied to a remote machine.  (Currently we use rsync, but that's
  rather inefficient.)

Eelco Dolstra 43c4d18c6a * nix-store --import': import an archive created by nix-store
--export' into the Nix store, and optionally check the cryptographic
  signatures against /nix/etc/nix/signing-key.pub.  (TODO: verify
  against a set of public keys.)
2007-02-21 15:45:32 +00:00
Eelco Dolstra 46e0919ced * `nix-store --export --sign': sign the Nix archive using the RSA key
in /nix/etc/nix/signing-key.sec
2007-02-21 14:31:42 +00:00
Eelco Dolstra b824a1daee * Start of `nix-store --export' operation for serialising a store
path.  This is like `nix-store --dump', only it also dumps the
  meta-information of the store path (references, deriver).  Will add
  a `--sign' flag later to add a cryptographic signature, which we
  will use for exchanging store paths between build farm machines in a
  secure manner.

Eelco Dolstra afe23b5f38 * nix-pack-closure: store the top-level store paths in the closure.
* nix-unpack-closure: extract the top-level paths from the closure and
  print them on stdout.  This allows them to be installed, e.g.,
  "nix-env -i $(nix-unpack-closure)".  (NIX-64)

Eelco Dolstra 4ca01065c3 * Rename all those main.cc files. 2006-12-07 20:47:30 +00:00
Renamed from src/nix-store/main.cc (Browse further)
