fa6a4fcb11 * Add ${sqlite_lib} everywhere. Just adding it in `libstore' doesn't
work on x86_64 when sqlite is compiled statically.

f25f900045 * Allow multiple --attr / -A arguments in nix-build / nix-instantiate
(NIX-74).

a9c4f66cfb * Allow unprivileged users to run the garbage collector and to do
`nix-store --delete'.  But unprivileged users are not allowed to
  ignore liveness.
* `nix-store --delete --ignore-liveness': ignore the runtime roots as
  well.

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.

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'.)

argument.

Eelco Dolstra
9638f3f393 * Pass the autoArgs to findAlongAttrPath so that "nix-instantiate
foo.nix -A attr --arg name value" will work if (name, value) is
  needed in the evaluation leading up to "attr".

24e234a2fa * Print attributes in sorted order, rather than the arbitrary order
produced by ATermMap.  Necessary for testing.
* `--strict' should also work on stdin.
2006-08-17 08:53:08 +00:00
Eelco Dolstra
22ba63df16 * More XML output. `--strict' to strictly evaluate attribute sets and
so on.
* Removed `--print-args', it's subsumed by `--eval-only --xml'.
2006-08-16 21:59:53 +00:00
Eelco Dolstra
18e4ac0fc6 * `nix-instantiate --{eval|parse}-only --xml': print an XML
representation instead of an ATerm.
* Indent XML output.

4661282fde * `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed

c11839d7b2 * `nix-instantiate --print-args': print out the valid values for
functions arguments that have a domain.

Eelco Dolstra
ca2238cf81 * Refactoring: get the selection path stuff out of getDerivations()
and put it into a separate function findAlongAttrPath().

982399bb14 * Enable the --attr in nix-build as well (and add -A as an alias).
Example:

    $ nix-build ./all-packages.nix -A xlibs.libX11

  So finally it's easy to perform a test build of a Nix expression!

c6120352b3 * In nix-instantiate, allow us to specify a "path" to the
derivation(s) we're interested, e.g.,

    $ nix-instantiate ./all-packages.nix --attr xlibs.libX11

  List elements can also be selected:

    $ nix-instantiate ./build-for-release.nix --attr 0.subversion

  This allows a non-ambiguous specification of a derivation.  Of
  course, this should also be added to nix-env and nix-build.

4c20a08293 * Build dynamic libraries. 2005-07-22 14:52:45 +00:00
Eelco Dolstra
22d3587f3b * In nix-instantiate, at top-level, call functions that have arguments
with default values automatically.  I.e., e -> e {}.

  This feature makes convenience expressions such as
  pkgs/system/i686-linux.nix in Nixpkgs obsolete, since we can just do

  $ nix-instantiate ./pkgs/system/all-packages.nix

  since all-packages.nix takes a single argument (system) that has a
  default value (__thisSystem).

630ae0c9d7 * nix-build: use an indirection scheme to make it easier for users to
get rid of GC roots.  Nix-build places a symlink `result' in the
  current directory.  Previously, removing that symlink would not
  remove the store path being linked to as a GC root.  Now, the GC
  root created by nix-build is actually a symlink in
  `/nix/var/nix/gcroots/auto' to `result'.  So if that symlink is
  removed the GC root automatically becomes invalid (since it can no
  longer be resolved).  The root itself is not automatically removed -
  the garbage collector should delete dangling roots.

dcc37c236c * nix-store, nix-instantiate: added an option `--add-root' to
immediately add the result as a permanent GC root.  This is the only
  way to prevent a race with the garbage collector.  For instance, the
  old style

    ln -s $(nix-store -r $(nix-instantiate foo.nix)) \
      /nix/var/nix/gcroots/result

  has two time windows in which the garbage collector can interfere
  (by GC'ing the derivation and the output, respectively).  On the
  other hand,

    nix-store --add-root /nix/var/nix/gcroots/result -r \
      $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \
        foo.nix)

  is safe.

* nix-build: use `--add-root' to prevent GC races.

96de272b48 * Renamed normalise.cc' -> build.cc', `storeexprs.cc' ->
`derivations.cc', etc.
* Store the SHA-256 content hash of store paths in the database after
  they have been built/added.  This is so that we can check whether
  the store has been messed with (a la `rpm --verify').
* When registering path validity, verify that the closure property
  holds.

a69534fc21 * Drop ATmake / ATMatcher also in handling store expressions. 2004-10-29 11:22:49 +00:00
Eelco Dolstra
5fe9222b36 * Don't use ATmake / ATmatch anymore, nor the ATMatcher class.
Instead we generate data bindings (build and match functions) for
  the constructors specified in `constructors.def'.  In particular
  this removes the conversions between AFuns and strings, and Nix
  expression evaluation now seems 3 to 4 times faster.

ee401afad8 * Mode --parse-only' to parse the input (on stdin, -'), and print
out the AST as an ATerm.
* Mode `--eval-only' to parse and evaluate the input, and print the
  resulting normal form as an ATerm.

Neither of these modes require store/DB write permission.

638ce339a5 * Nix-instantiate now accepts sets of derivations (just like nix-env). 2004-07-01 14:25:26 +00:00
Eelco Dolstra
59b94ee18a * When something goes wrong in the evaluation of a Nix expression,
print a nice backtrace of the stack, rather than vomiting a gigantic
  (and useless) aterm on the screen.  Example:

    error: while evaluating file `.../pkgs/system/test.nix':
    while evaluating attribute `subversion' at `.../pkgs/system/all-packages-generic.nix', line 533:
    while evaluating function at `.../pkgs/applications/version-management/subversion/default.nix', line 1:
    assertion failed at `.../pkgs/applications/version-management/subversion/default.nix', line 13

  Since the Nix expression language is lazy, the trace may be
  misleading.  The purpose is to provide a hint as to the location of
  the problem.
