Eelco Dolstra 52d03276dd * Compatibility with docbook5-xsl. 2007-02-05 12:10:10 +00:00
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 f52de527c7 * Doh! 2007-01-29 15:55:49 +00:00
Eelco Dolstra b618fa6eb6 * computeStorePathForText: take the references into account when
computing the store path (NIX-77).  This is an important security
  property in multi-user Nix stores.

  Note that this changes the store paths of derivations (since the
  derivation aterms are added using addTextToStore), but not most
  outputs (unless they use builtins.toFile).
2007-01-29 15:51:37 +00:00
Eelco Dolstra c558b1583c * Don't capitalise the primop functions. 2007-01-29 15:15:37 +00:00
Eelco Dolstra 18e6096105 * Organise primops.cc a bit better. 2007-01-29 15:11:32 +00:00
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.
2007-01-29 14:23:09 +00:00
Eelco Dolstra 7dedbd896a * filterSource: pass strings to the predicate function instead of
paths.  Paths can have unexpected semantics.
2007-01-29 13:32:50 +00:00
Eelco Dolstra 84a84afb0e * Nasty: Glibc clears the TMPDIR environment variable in setuid
programs, so if a builder uses TMPDIR, then it will fail when
  executed through nix-setuid-helper.  In fact Glibc clears a whole
  bunch of variables (see sysdeps/generic/unsecvars.h in the Glibc
  sources), but only TMPDIR should matter in practice.  As a
  workaround, we reinitialise TMPDIR from NIX_BUILD_TOP.
2007-01-24 13:31:20 +00:00
Eelco Dolstra fac63d6416 * exportReferencesGraph: work on paths within store paths as well. 2007-01-23 16:57:43 +00:00
Eelco Dolstra 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.
2007-01-23 16:50:19 +00:00
Eelco Dolstra 36d9258c0d * Successors have been gone for ages. 2007-01-23 16:05:59 +00:00
Eelco Dolstra 7bc30e1ca8 * nix-prefetch-url: change the default hash to SHA-256 (in base-32). 2007-01-22 09:53:36 +00:00
Eelco Dolstra 71ceb1c161 * Handle multiple indirect symlinks when loading a Nix expression. 2007-01-15 14:50:25 +00:00
Eelco Dolstra e4b0666f8e * builtins.filterSource: pass the type of the file ("regular",
"directory", "symlink") as the second argument to the filter
  predicate.
2007-01-15 08:54:51 +00:00
Eelco Dolstra 63f3ce6d9a * `nix-store --verify': revive checking the referrers table. This is
important to get garbage collection to work if there is any
  inconsistency in the database (because the referrer table is used to
  determine whether it is safe to delete a path).
* `nix-store --verify': show some progress.
2007-01-14 17:28:30 +00:00
Eelco Dolstra 8f67b35886 * Make the garbage collector more resilient to certain consistency
errors: in-use paths now cause a warning, not a fatal error.
2007-01-14 16:24:49 +00:00
Eelco Dolstra 8659edc098 * Don't forget the .flags files. 2007-01-14 12:33:04 +00:00
Eelco Dolstra e418976107 * Option --argstr for passing string arguments easily. (NIX-75) 2007-01-14 12:32:44 +00:00
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.
