Eelco Dolstra 4e329f173f * Doh. 2007-01-14 12:16:58 +00:00
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)
2007-01-13 19:50:42 +00:00
Eelco Dolstra f25f900045 * Allow multiple --attr / -A arguments in nix-build / nix-instantiate
(NIX-74).
2007-01-13 18:25:30 +00:00
Eelco Dolstra 215505bb46 * Removed chroot support. 2007-01-13 17:54:01 +00:00
Eelco Dolstra f23dcdd603 * Canonicalise ASTs in `nix-instantiate --eval': remove position
info, sort attribute sets.
2007-01-13 16:17:07 +00:00
Eelco Dolstra 05879db628 * Memoize strict evaluation. 2007-01-13 15:41:54 +00:00
Eelco Dolstra 5011588459 * printTermAsXML: treat derivations specially; emit an element
<derivation outPath=... drvPath=...> attrs </derivation>.  Only emit
  the attributes of any specific derivation only.  This prevents
  exponententially large XML output due to the absense of sharing.
2007-01-13 15:11:10 +00:00
Eelco Dolstra 792878af91 * Make printing an expression as XML interruptible. 2007-01-13 14:48:41 +00:00
Eelco Dolstra 11158028be * Cleanup. 2007-01-13 14:21:49 +00:00
Eelco Dolstra 1b7840b949 2007-01-11 19:28:28 +00:00
Eelco Dolstra 69c8b5b8a7 * Install generate-patches into libexec. 2007-01-11 16:19:45 +00:00
Eelco Dolstra 1f3722bd4a * Reject patches that are larger than a certain fraction of the full archive
(currently 60%).  Large patches aren't very economical.
2007-01-08 15:32:15 +00:00
Eelco Dolstra 50bdec410a * Huge speedup in patch propagation (20 minutes or so to 3 seconds). 2007-01-08 15:17:18 +00:00
Eelco Dolstra 4c63f9fe04 * Another great success. 2006-12-29 22:23:51 +00:00
Eelco Dolstra 57969b95b3 * Testing 1 2 3. 2006-12-29 20:37:55 +00:00
Eelco Dolstra cafaceb707 * Handle weird cases when the server redirects us while setting a cookie. 2006-12-15 21:27:26 +00:00
Eelco Dolstra 1073b1780a * Remove debug message. 2006-12-13 14:29:05 +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.
2006-12-12 23:05:01 +00:00
Eelco Dolstra b438d37558 * In dumpPath(): pass a function object that allows files to be
selectively in/excluded from the dump.
2006-12-12 21:51:02 +00:00
Eelco Dolstra 3130f1f0fa * Push. 2006-12-12 20:17:14 +00:00
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.
2006-12-12 19:06:02 +00:00
Eelco Dolstra 1a7e88bbd9 * New built-in function `builtins.attrNames' that returns the
names of the attributes in an attribute set.
2006-12-12 16:14:31 +00:00
Eelco Dolstra 5e6699188f 2006-12-09 23:14:55 +00:00
Eelco Dolstra b17677462c * Use lchown() instead of chown() in canonicalisePathMetaData(). This
matters when running as root, since then we don't use the setuid
  helper (which already used lchown()).
  
* Also check for an obscure security problem on platforms that don't
  have lchown.  Then we can't change the ownership of symlinks, which
  doesn't matter *except* when the containing directory is writable by
  the owner (which is the case with the top-level Nix store directory).
2006-12-09 20:02:27 +00:00
Eelco Dolstra 5f681988f2 * Use deletePathWrapped() in more places. 2006-12-09 00:26:24 +00:00
Eelco Dolstra fa33303146 * Goal cancellation inside the waitForInput() loop needs to be handled
very carefully, since it can invalidate iterators into the
  `children' map.
2006-12-08 18:41:48 +00:00
Eelco Dolstra 06c4929958 * Some refactoring.
* Throw more exceptions as BuildErrors instead of Errors.  This
  matters when --keep-going is turned on.  (A BuildError is caught
  and terminates the goal in question, an Error terminates the
  program.)
2006-12-08 17:26:21 +00:00
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.
2006-12-08 15:44:00 +00:00
Eelco Dolstra d3fe6ab024 * Also for convenience, change the ownership of the build output even
in case of failure.
2006-12-08 00:19:50 +00:00
Eelco Dolstra 096194ab29 * Remove ancient terminology. 2006-12-07 23:58:36 +00:00
Eelco Dolstra 6833e8bbe8 * When keeping the temporary build directory (-K), change the owner
back to the Nix account.
2006-12-07 23:27:40 +00:00
Eelco Dolstra e24d0201c2 * Doh! 2006-12-07 22:07:05 +00:00
Eelco Dolstra 2819eb36a4 * Be less verbose. 2006-12-07 21:43:35 +00:00
Eelco Dolstra 4ca01065c3 * Rename all those main.cc files. 2006-12-07 20:47:30 +00:00
Eelco Dolstra d03f0d4117 * Check for lchown. 2006-12-07 18:51:11 +00:00
Eelco Dolstra c3286ec020 * Don't count on the Pid deconstructor to kill the child process,
since if we're running a build user in non-root mode, we can't.  Let
  the setuid helper do it.
2006-12-07 17:52:58 +00:00
Eelco Dolstra a82d80ddeb * Move setuidCleanup() to libutil. 2006-12-07 16:40:41 +00:00
Eelco Dolstra f76fdb6d42 * If not running as root, let the setuid helper kill the build user's
processes before and after the build.
2006-12-07 16:33:31 +00:00
Eelco Dolstra ec23ecc64d * In the garbage collector, if deleting a path fails, try to fix its
ownership, then try again.
2006-12-07 15:54:52 +00:00
Eelco Dolstra a0a43c3206 * When not running as root, call the setuid helper to change the
ownership of the build result after the build.
2006-12-07 15:18:14 +00:00
Eelco Dolstra 6a07ff1ec0 * Change the ownership of store paths to the Nix account before
deleting them using the setuid helper.
2006-12-07 14:14:35 +00:00
Eelco Dolstra 7d8cf316ee * Pass the actual build user to the setuid helper. 2006-12-07 11:27:32 +00:00
Eelco Dolstra a45c498e4e * If Nix is not running as root, call the setuid helper to start the
builder under the desired build user.
2006-12-07 00:42:30 +00:00
Eelco Dolstra 813a7c65c9 * Sanity check. 2006-12-07 00:19:27 +00:00
Eelco Dolstra 6a8e60913a * Move killUser() to libutil so that the setuid helper can use it. 2006-12-07 00:16:07 +00:00
Eelco Dolstra 79875c5e42 * Change the ownership of the current directory to the build user. 2006-12-06 23:52:25 +00:00
Eelco Dolstra 62ab131412 * Verify that the desired target user is in the build users group (as
specified in the setuid config file).
2006-12-06 23:15:26 +00:00
Eelco Dolstra f07ac41656 * Check that the caller is allowed to call the setuid helper. The
allowed uid is specified in a configuration file in
  /etc/nix-setuid.conf.
2006-12-06 22:45:41 +00:00
Eelco Dolstra 173d328351 * Urgh. 2006-12-06 20:19:25 +00:00
Eelco Dolstra ef281b93c2 * Fix the safety check. 2006-12-06 20:18:29 +00:00
