Eelco Dolstra 6ecb840fd1 * Put building in the store API. 2006-11-30 18:02:04 +00:00
Eelco Dolstra e2ef5e07fd * Refactoring. There is now an abstract interface class StoreAPI
containing functions that operate on the Nix store.  One
  implementation is LocalStore, which operates on the Nix store
  directly.  The next step, to enable secure multi-user Nix, is to
  create a different implementation RemoteStore that talks to a
  privileged daemon process that uses LocalStore to perform the actual
  operations.

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 a76efaeb3f * Dead files. 2006-11-24 20:07:30 +00:00
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.
2006-11-13 18:19:05 +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).
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'.)
