Eelco Dolstra fe15f991e3 * Troubleshooting information on fixing a b0rked Berkeley DB database. 2006-11-30 11:24:10 +00:00
Eelco Dolstra 80b742dd52 * Don't spam. 2006-11-29 22:07:49 +00:00
Roy van den Broek 92417600a1 * Example script to set permissions for setuid operation. 2006-11-29 21:58:09 +00:00
Eelco Dolstra 71e867c5f5 * Remove --enable-setuid, --with-nix-user and --with-nix-group.
Rather, setuid support is now always compiled in (at least on
  platforms that have the setresuid system call, e.g., Linux and
  FreeBSD), but it must enabled by chowning/chmodding the Nix
  binaries.

Eelco Dolstra c6a97e3b74 * Doh! Path sizes need to be computed recursively of course.

Eelco Dolstra d941186289 * Show more progress. 2006-11-18 19:03:45 +00:00
Eelco Dolstra 0541ddc7e3 * Turn off synchronisation between C and C++ I/O functions. This
gives a huge speedup in operations that read or write from standard
  input/output.  (So libstdc++'s I/O isn't that bad, you just have to
  call std::ios::sync_with_stdio(false).)  For instance, `nix-store
  --register-substitutes' went from 1.4 seconds to 0.1 seconds on a
  certain input.  Another victory for Valgrind.

Eelco Dolstra f459a5bb3a * Remove the undocumented `noscan' feature. It's no longer necessary
now that reference scanning is sufficiently streamy.

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).
2006-11-13 18:18:13 +00:00
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 e790404318 * Don't use the result of `uname -p' on x86_64 as it gives wacky
results on some machines. (NIX-69)

Eelco Dolstra 8d17265ac4 * Don't use EPSV. 2006-10-28 22:07:09 +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 b3d3700e11 * nix-build: check the exit status of `nix-store -r'. 2006-10-19 17:30:09 +00:00
Eelco Dolstra 6a67556f71 * Special derivation attribute `allowedReferences' that causes Nix to
check that the references of the output of a derivation are in the
  specified set.  For instance,

    allowedReferences = [];

  specifies that the output cannot have any references.  (This is
  useful, for instance, for the generation of bootstrap binaries for
  stdenv-linux, which must not have any references for purity).  It
  could also be used to guard against undesired runtime dependencies,
  e.g.,

    {gcc, dynlib}: derivation {
      ...
      allowedReferences = [dynlib];
    }

  says that the output can refer to the path of `dynlib' but not
  `gcc'.  A `forbiddedReferences' attribute would be more useful for
  this, though.

Eelco Dolstra be1961c9f8 * toPath: should be the identity on paths. 2006-10-17 11:07:11 +00:00
Eelco Dolstra cba913c521 * dirOf: return a path if the argument is a path. 2006-10-17 11:05:34 +00:00
Eelco Dolstra cf705eaf78 * toString: don't copy paths. So toString can be used to pass
non-store paths to a builder.
2006-10-17 10:58:12 +00:00
Eelco Dolstra 7de5fe2fc2 * Do the path check on the normal form. 2006-10-17 10:57:25 +00:00
Eelco Dolstra 46b631b6c4 * Don't generate an empty drvPath attribute in the manifest. 2006-10-17 10:15:42 +00:00
Eelco Dolstra d7efd76394 * Big cleanup of the semantics of paths, strings, contexts, string
concatenation and string coercion.  This was a big mess (see
  e.g. NIX-67).  Contexts are now folded into strings, so that they
  don't cause evaluation errors when they're not expected.  The
  semantics of paths has been clarified (see nixexpr-ast.def).
  toString() and coerceToString() have been merged.

  Semantic change: paths are now copied to the store when they're in a
  concatenation (and in most other situations - that's the
  formalisation of the meaning of a path).  So

    "foo " + ./bla

  evaluates to "foo /nix/store/hash...-bla", not "foo
  /path/to/current-dir/bla".  This prevents accidental impurities, and
  is more consistent with the treatment of derivation outputs, e.g.,
  `"foo " + bla' where `bla' is a derivation.  (Here `bla' would be
  replaced by the output path of `bla'.)
