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 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 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 005eecfc4d * Release notes. 2006-10-30 16:29:05 +00:00
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.

Eelco Dolstra f316b6c1a9 * Manual updates (especially how nix-build makes testing packages much
easier; no longer need a helper expression).

Eelco Dolstra f41297fdce * Allow --arg in nix-env as well, example:
$ nix-env -qa --system-filter \* --arg system '"powerpc-darwin"'

  to override the system from the default value (__currentSystem in
  all-packages.nix).

Eelco Dolstra 1a9a1f2768 * Convert to DocBook 5.
* Use Jing for RelaxNG validation, xmllint seems buggy.

Eelco Dolstra b11aeb2c4b * Doh. 2006-07-25 13:15:23 +00:00
Eelco Dolstra 5744dd5480 * Support the --attr / -A flag in nix-env as well. So now we can do,
e.g.,

  $ nix-env -i -A subversion xorg.xorgserver

  The main advantage over using symbolic names is that using attribute
  names is unambiguous and much, much faster.

Eelco Dolstra c15f544356 * Call find-runtime-roots.pl from the garbage collector to prevent
running applications etc. from being garbage collected.

Eelco Dolstra 50fe85f016 * For fixed-output derivations, pass the environment variables listed
in the attribute variable `impureEnvVars' from the caller to the
  builder.

Eelco Dolstra ab5c6bb3a3 * Change referer' to referrer' throughout. In particular, the
nix-store query options `--referer' and `--referer-closure' have
  been changed to `--referrer' and `--referrer-closure' (but the old
  ones are still accepted for compatibility).

Eelco Dolstra 025086edea * Release notes in Docbook; ASCII release notes (i.e., the `NEWS'
file) is now generated from that using `w3m' and some XSL hackery.
