Peter Simons 8b7f8b56f1 Added support for passing an (impure) NIX_BUILD_CORES variable to build expressions. 
This patch adds the configuration file variable "build-cores" and the
command line argument "--cores". These settings specify the number of
CPU cores to utilize for parallel building within a job, i.e. by passing
an appropriate "-j" flag to GNU Make. The default value is 1, which
means that parallel building is *disabled*. If the number of build cores
is specified as 0 (synonymously: "guess" or "auto"), then the actual
value is supposed to be auto-detected by builders at run-time, i.e by
calling the nproc(1) utility from coreutils.

The environment variable $NIX_BUILD_CORES is available to builders, but
the contents of that variable does *not* influence the hash that goes
into the $out store path, i.e. the number of build cores to be utilized
can be changed at will without requiring any re-builds.

Eelco Dolstra 819548d92f * Pass `--fallback' to the remote build to ignore failing 
substituters.

Eelco Dolstra b57189174f * In importPath() and exportPath(), lock the temporary directory to 
prevent it from being deleted by the garbage collector.

Eelco Dolstra f16fe2af8d * builtins.toXML: propagate the string context. This is a regression 
from the old ATerm-based evaluator.

Lluís Batlle i Rossell d77331d32f Fixing a typo in the nix-store manual, that could confuse a bit too much (--delete/--gc) 2010-04-25 20:52:49 +00:00
Eelco Dolstra 2be6118f4c * Don't need the test program anymore. 2010-04-23 09:09:32 +00:00
Eelco Dolstra 0bc468f195 * Simplify the implementation of `with'. This gives a 7% speedup in 
evaluating the NixOS system configuration.

Eelco Dolstra ebade9ff8b * Check for duplicate attribute names / function arguments. `make 
check' now succeeds :-)
* An attribute set such as `{ foo = { enable = true; };
  foo.port = 23; }' now parses.  It was previously rejected, but I'm
  too lazy to implement the check.  (The only reason to reject it is
  that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is
  rejected, which is kind of ugly.)

Eelco Dolstra 2d7636529f * String equality tests should take the context into account. All the 
evaluation test cases now succeed.
 2010-04-22 09:54:11 +00:00
Eelco Dolstra 6bbfe95e30 * Don't use an ostringstream in unparseDerivation(), because it's 
slow.  A `nix-env -qa --drv-path \*' on Nixpkgs was spending 40% of
  its time in unparseDerivation() because of this (now 11%).

Eelco Dolstra 7148df7971 * Update the expected test output (no longer an ATerm). 2010-04-21 16:22:03 +00:00
Eelco Dolstra 6f0f16497a * Fix the interpretation of ''\<character> in indented strings. 2010-04-21 16:18:27 +00:00
Eelco Dolstra cae4efdca3 * Because --parse-only no longer produces an ATerm, don't check the 
output.  Whether it parses at all should be enough.

Eelco Dolstra 0777448ca6 * Fixed builtins.genericClosure. 2010-04-21 15:57:11 +00:00
Eelco Dolstra fe2d869e04 * Store user environment manifests as a Nix expression in 
$out/manifest.nix rather than as an ATerm.

  (Hm, I thought I committed this two days ago...)
 2010-04-21 15:08:58 +00:00
Eelco Dolstra f3b8833a48 * Drop the dependency on the ATerm library. 2010-04-19 14:51:58 +00:00

Eelco Dolstra 5c31995bb8 * Updated some more primops. 2010-04-16 15:13:47 +00:00
Eelco Dolstra 8bb0210fea * _combineChannels shouldn't be an integer. 2010-04-16 14:07:52 +00:00
Eelco Dolstra 8ca4a001cb * Improve sharing a bit. 2010-04-16 14:03:26 +00:00
Eelco Dolstra 497e4ad126 * Remove some redundant tests. 2010-04-16 13:51:01 +00:00
Eelco Dolstra 02c1dac909 * In an nested with' where the inner with is a variable (with ...; 
with someVar; ...'), the contents of the variable would be
  clobbered.  (The attributes in the outer `with' were added to the
  variable.)
 2010-04-16 13:44:02 +00:00
Eelco Dolstra 04c4bd3624 * Store lists as lists of pointers to values rather than as lists of 
values.  This improves sharing and gives another speed up.
  Evaluation of the NixOS system attribute is now almost 7 times
  faster than the old evaluator.
