Eelco Dolstra 451dbf687f * nix-env now maintains meta info (from the `meta' derivation
attribute) about installed packages in user environments.  Thus, an
  operation like `nix-env -q --description' shows useful information
  not only on available packages but also on installed packages.

* nix-env now passes the entire manifest as an argument to the Nix
  expression of the user environment builder (not just a list of
  paths), so that in particular the user environment builder has
  access to the meta attributes.
  
* New operation `--set-flag' in nix-env to change meta info of
  installed packages.  This will be useful to pass per-package
  policies to the user environment builder (e.g., how to resolve
  collision or whether to disable a package (NIX-80)) or upgrade
  policies in nix-env (e.g., that a package should be "masked", that
  is, left untouched by upgrade actions).  Example:

  $ nix-env --set-flag enabled false ghc-6.4

Eelco Dolstra 7349bd0176 New primitives:
* `sub' to subtract two numbers.
* `stringLength' to get the length of a string.
* `substring' to get a substring of a string.  These should be enough
  to allow most string operations to be expressed.

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 215505bb46 * Removed chroot support. 2007-01-13 17:54:01 +00:00
Eelco Dolstra a3e6415ba8 * New primop builtins.filterSource, which can be used to filter files
from a source directory.  All files for which a predicate function
  returns true are copied to the store.  Typical example is to leave
  out the .svn directory:

    stdenv.mkDerivation {
      ...
      src = builtins.filterSource
        (path: baseNameOf (toString path) != ".svn")
        ./source-dir;
      # as opposed to
      #   src = ./source-dir;
    }

  This is important because the .svn directory influences the hash in
  a rather unpredictable and variable way.

Eelco Dolstra 7ace29dae7 * New operation `nix-env --set' which sets a user environment to a
single derivation specified by the argument.  This is useful when we
  want to have a profile for a single derivation, such as a server
  configuration.  Then we can just say (e.g.)

  $ nix-env -p /.../server-profile -f server.nix --set -A server

  We can't do queries or upgrades on such a profile, but we can do
  rollbacks.  The advantage over -i is that we don't have to worry
  about other packages having been installed in the profile
  previously; --set gets rid of them.

Eelco Dolstra 1a7e88bbd9 * New built-in function `builtins.attrNames' that returns the
names of the attributes in an attribute set.

Eelco Dolstra 9dbfe242e3 * Kill a build if it has gone for more than a certain number of
seconds without producing output on stdout or stderr (NIX-65).  This
  timeout can be specified using the `--max-silent-time' option or the
  `build-max-silent-time' configuration setting.  The default is
  infinity (0).

* Fix a tricky race condition: if we kill the build user before the
  child has done its setuid() to the build user uid, then it won't be
  killed, and we'll potentially lock up in pid.wait().  So also send a
  conventional kill to the child.

Eelco Dolstra fe15f991e3 * Troubleshooting information on fixing a b0rked Berkeley DB database. 2006-11-30 11:24:10 +00:00
Eelco Dolstra 745e354b19 * Push. 2006-11-14 10:23:21 +00:00
Eelco Dolstra e2a70b7ec0 * Magic attribute `exportReferencesGraph' that allows the references
graph to be passed to a builder.  This attribute should be a list of
  pairs [name1 path1 name2 path2 ...].  The references graph of each
  `pathN' will be stored in a text file `nameN' in the temporary build
  directory.  The text files have the format used by `nix-store
  --register-validity'.  However, the deriver fields are left empty.

  `exportReferencesGraph' is useful for builders that want to do
  something with the closure of a store path.  Examples: the builders
  that make initrds and ISO images for NixOS.

  `exportReferencesGraph' is entirely pure.  It's necessary because
  otherwise the only way for a builder to get this information would
  be to call `nix-store' directly, which is not allowed (though
  unfortunately possible).

Eelco Dolstra e40d4a5604 * Option --reregister' in nix-store --register-validity'. We need
this in the NixOS installer (or in the buildfarm) to ensure that the
  cryptographic hash of the path contents still matches the actual
  contents.

Eelco Dolstra ae6fb27f18 * `nix-store --read-log / -l PATH' shows the build log of PATH, if
available.  For instance,

    $ nix-store -l $(which svn) | less

  lets you read the build log of the Subversion instance in your
  profile.

* `nix-store -qb': if applied to a non-derivation, take the deriver.
