Eelco Dolstra 4dee289550 * In environments, store pointers to values rather than values. This
improves GC effectiveness a bit more (because a live value doesn't
  keep other values in the environment plus the parent environments
  alive), and removes the need for copy nodes.

Eelco Dolstra cf7e645a48 * Regression test for __overrides. 2010-10-22 15:15:12 +00:00
Eelco Dolstra 41c45a9b31 * Store Value nodes outside of attribute sets. I.e., Attr now stores
a pointer to a Value, rather than the Value directly.  This improves
  the effectiveness of garbage collection a lot: if the Value is
  stored inside the set directly, then any live pointer to the Value
  causes all other attributes in the set to be live as well.

Eelco Dolstra 64c3325b0b * Make building against the Boehm GC a configure option. 2010-10-22 13:39:15 +00:00

Eelco Dolstra e879a0371b * Use the Boehm garbage collector to reclaim unused memory in the Nix
expression evaluator.

Rob Vermaas 8dadcede65 nix manual: fix 'install' -> 'uninstall' in garbage collection section of introduction 2010-10-06 19:04:04 +00:00
Eelco Dolstra 7119d38287 * In the referrers test, lower the nesting depth from 2500 to 1000 to
prevent hitting a stack overflow bug in the garbage collector.

Eelco Dolstra 705868a8a9 * Make sure that config.h is included before the system headers,
because it defines _FILE_OFFSET_BITS.  Without this, on 
  OpenSolaris the system headers define it to be 32, and then 
  the 32-bit stat() ends up being called with a 64-bit "struct 
  stat", or vice versa.

  This also ensures that we get 64-bit file sizes everywhere.

* Remove the redundant call to stat() in parseExprFromFile().
  The file cannot be a symlink because that's the exit condition
  of the loop before.

Eelco Dolstra 95f4f2cf61 * If std::tr1::unordered_set is unavailable, use std::set. 2010-10-04 16:16:19 +00:00
Eelco Dolstra 36a23e86b6 * "type -P" isn't portable. 2010-10-04 15:50:08 +00:00
Eelco Dolstra 450837bcc8 * In printMsg(), ignore failing writes to stderr if we're in an
exception handler, otherwise throw an exception.  We need to ignore
  write errors in exception handlers to ensure that cleanup code runs
  to completion if the other side of stderr has been closed
  unexpectedly.

Eelco Dolstra 12721a3a9a * Nix 0.16 release notes. 2010-08-16 12:38:32 +00:00
Eelco Dolstra 5fb824e896 * Urgh, this was supposed to go in the trunk... 2010-08-12 13:36:56 +00:00
Eelco Dolstra 6846ed8b44 * Make --cores work when building through the Nix daemon. 2010-08-12 09:21:50 +00:00
Eelco Dolstra 750be19ae8 * Remove "auto" and "guess" as synonyms for 0 in the handling of
build-cores and --cores.  They're superfluous and just complicate
  the parsing.
2010-08-04 12:23:59 +00:00
Eelco Dolstra 315d8fbd75 * Set the default system filter to "*". This ensures that (for
instance) "nix-env -i wine" works on x86_64-linux, even though Wine
  is built on i686-linux.  In the event that there are multiple
  matching derivations, prefer those built for the current system.

Eelco Dolstra 6d6200f37a * Optimisation in the // operator: if one of the sets is empty, return
the other set.
2010-08-02 16:31:05 +00:00
Eelco Dolstra 7af6a2fd71 * intersectAttrs: optimise for the case where the second set is larger
than the first set.  (That's usually the case with callPackage.)

Eelco Dolstra 532d766c27 * Don't barf if the source NAR for a patch has disappeared. 2010-07-21 11:30:23 +00:00
Peter Simons 7e043d28a6 src/bsdiff-4.3/Makefile.am: include the 'compat-include' directory in distribution tarballs 2010-07-15 14:35:20 +00:00
Peter Simons 60b632b173 tests/build-hook.hook.sh: prefer more portable ... syntax over $(...) for running sub-shells
The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running
sub-shells. Consequently, this test fails on Solaris. To remedy the situation,
the script either needs to be run by /bin/bash -- which is non-standard --, or
it needs to use the ancient but portable `...` syntax.

Peter Simons a0d29040f7 Revert "configure.ac: make flex and bison required programs"
This reverts commit 22405. Apparently, these programs aren't necessarily
required when building from a release archive.

Peter Simons af09fe12dd Fix build of bsdiff-4.3 on machines that don't have <err.h>, such as Solaris. 2010-06-24 17:51:31 +00:00
Peter Simons d63375d529 configure.ac: Incredibly enough, tr(1) on Solaris doesn't understand A-Z syntax for ranges. 2010-06-24 17:51:24 +00:00
Peter Simons 4c21c016c5 configure.ac: make flex and bison required programs
The build fails if these tools aren't available.

Peter Simons bcec46057c src/libutil/util.cc: include <limit.h> to ensure that PATH_MAX is defined 2010-06-24 17:51:13 +00:00
Peter Simons a17071fef1 Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared.
An "using namespace std" was added locally in those functions that refer to
names from <cstring>. That is not pretty, but it's a very portable solution,
because strcpy() and friends will be found in both the 'std' and in the global
namespace.

Eelco Dolstra 560ab22f7d * Ignore packages that don't have a version.
* Work on a manifest instead of a channel directory.

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.
2010-06-22 14:41:22 +00:00
Eelco Dolstra b57189174f * In importPath() and exportPath(), lock the temporary directory to
prevent it from being deleted by the garbage collector.
2010-06-14 08:34:48 +00:00
Eelco Dolstra f16fe2af8d * builtins.toXML: propagate the string context. This is a regression
from the old ATerm-based evaluator.
2010-06-10 10:29:50 +00:00
Eelco Dolstra 07ca66cf24 * Applied a patch from David Brown to prevent `nix-store --optimise'
from failing on rename() on BtrFS.

Eelco Dolstra 89865da76d * Turn build errors during evaluation into EvalErrors. 2010-06-01 11:19:32 +00:00
Ludovic Courtès 8bcdd36f10 Add XML output to `nix-store'.
* src/nix-store/Makefile.am (nix_store_SOURCES): Add `xmlgraph.cc' and
  `xmlgraph.hh'.

* src/nix-store/help.txt (Operations): Document `--xml'.

Ludovic Courtès da52f8bea0 Comment out dead code in `nix-store'.
