Eelco Dolstra f491ae97d4 * Inline some functions and get rid of the indirection through 
EvalState::eval().  This gives a 12% speedup on ‘nix-instantiate
  /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s).
 2012-02-04 13:50:25 +00:00
Eelco Dolstra 2bda12ef3b * Print elapsed evaluation time. 2012-02-04 13:27:11 +00:00
Eelco Dolstra ce86a9a0ae * nix-channel: fail if we don't have write permission to the manifests 
directory.  Previously in this situation we did add the Nix
  expressions from the channel to allow installation from source, but
  this doesn't work for binary-only channels and leads to confusing
  error messages.

Eelco Dolstra baa0501cc1 * Fix importing a derivation. This gave a segfault. 2012-01-26 13:13:00 +00:00
Eelco Dolstra 4c9fdd2cd6 * Add a test for importing derivations. 2012-01-26 13:04:50 +00:00
Eelco Dolstra 330df4b4db * Allow comparisons between derivations by comparing the outPath 
attributes.
 2012-01-19 23:08:47 +00:00
Eelco Dolstra 18047d4625 * Add some debug output to print the derivation name once it's known. 
This makes it easier to pinpoint the source of a crash.
 2012-01-19 23:07:42 +00:00
Eelco Dolstra 126c7317bc * Add a test case for comparing derivations. 2012-01-19 22:10:24 +00:00
Eelco Dolstra ddd0ce534a * Don't distribute Store.cc, it's generated automatically by xsubpp. 2012-01-18 16:43:48 +00:00
Eelco Dolstra 02f1363e19 * Pass the appropriate flags to GCC when building the Perl bindings. 
Without these, Nix fails on 32-bit Linux with Perl 5.14, with a
  rather unhelpful error message:

    Not a CODE reference at /nix/store/n6kpbacn6nn7i3i735v8j3di8aqyl07v-perl-5.14.2/lib/perl5/5.14.2/i686-linux-thread-multi/DynaLoader.pm

  This is likely because the lack of -D_FILE_OFFSET_BITS=64 causes
  various Perl structures to not match what the Perl interpreter
  expects.
 2012-01-18 16:39:54 +00:00
Eelco Dolstra 4e624849b6 * Added a command ‘nix-store --print-env $drvpath’ that prints out the 
environment of the given derivation in a format that can be sourced
  by the shell, e.g.

  $ eval "$(nix-store --print-env $(nix-instantiate /etc/nixos/nixpkgs -A pkg))"
  $ NIX_BUILD_TOP=/tmp
  $ source $stdenv/setup

  This is especially useful to reproduce the environment used to build
  a package outside of its builder for development purposes.

  TODO: add a nix-build option to do the above and fetch the
  dependencies of the derivation as well.
 2012-01-17 23:07:22 +00:00
Eelco Dolstra 2a3f4110c5 * nix-build: put the temporary derivation symlink in a temporary 
directory rather than the current directory.
* nix-build: --drv-link now implies --add-drv-link.
 2012-01-13 23:35:07 +00:00
Eelco Dolstra 7ae763e16b * ‘-module’ causes the generated library to have an .so extension on 
Mac OS X instead of .dylib, so don't do that.
 2012-01-12 14:16:25 +00:00
Ludovic Courtès 6245f0d529 tests: Run `download-using-manifests' via libtool so that dlopening works. 2012-01-11 16:58:49 +00:00
Ludovic Courtès c5d9ccd810 perl: Build libNixStore.la with `-module'. 2012-01-11 16:44:42 +00:00
Eelco Dolstra f86fca9b70 * Figure out the extension of dynamic libraries; don't hard-code .so. 2012-01-11 15:41:42 +00:00
Eelco Dolstra 9fe24c5a0d * Don't create thunks for simple constants (integers, strings, paths) 
and allocate them only once.
* Move Value and related functions into value.hh.
 2012-01-07 17:26:33 +00:00
Eelco Dolstra d4e6b9f2d6 * Doh! 2012-01-05 21:07:12 +00:00
Eelco Dolstra a7366a764a * Add a -I flag to the Perl bindings to nix-build and some other 
scripts.
* Include the version and architecture in the -I flag so that there is
  at least a chance that a Nix binary built for one Perl version will
  run on another version.
 2012-01-05 20:33:46 +00:00
Eelco Dolstra b52966e821 * Remove dead code. 2012-01-04 21:47:48 +00:00
Eelco Dolstra 35f2a6ba82 * Don't use dynamic_cast, it's very slow. "nix-instantiate 
/etc/nixos/nixos -A system" spent about 10% of its time in
  dynamic_cast.
 2012-01-04 21:24:11 +00:00
Eelco Dolstra adaf64a99b * Merge the multiple-outputs-sandbox branch (svn merge --reintegrate 
^/nix/branches/multiple-outputs-sandbox).  Multiple output support
  still isn't complete, but it wasn't complete in the trunk either, so
  it doesn't hurt.
 2012-01-04 16:22:25 +00:00
Eelco Dolstra 9936da6b54 * Check whether the outputName attribute works. 2012-01-04 12:45:53 +00:00
Eelco Dolstra 9d43a02382 * Let --disable-gc work. 2012-01-04 12:45:40 +00:00
Eelco Dolstra a0477a458f * currentOutput -> outputName. "current" implies some temporal 
aspect.
 2012-01-04 12:00:39 +00:00
Eelco Dolstra b79b85ad76 * Export the original input attributes of the derivation in 
‘drvAttrs’.  This will simplify the implementation of functions such
  as ‘overrideDerivation’ in Nixpkgs, which need to filter out any
  added attributes such as outPath.
 2012-01-04 11:56:15 +00:00
Eelco Dolstra 83647f4ef1 * Simplify the implementation of "derivation" a bit: lift out the 
common attribution so that they're evaluated only once, etc.  Note
  that the default output is now the first element of the "outputs"
  attribute, rather than the first element of the sorted list of
  outputs.  This seems more user-friendly.
 2012-01-04 11:04:19 +00:00
Eelco Dolstra 71f3c46cf6 * Drop the inefficient "Path" suffix in output attribute names. 2012-01-03 15:27:18 +00:00
Eelco Dolstra 921111d197 * Move the implementation of the ‘derivation’ primop into a separate 
file.
 2012-01-03 14:01:47 +00:00
Eelco Dolstra 6c31232e14 * Sync with the trunk. 2012-01-03 12:59:31 +00:00
Eelco Dolstra 502d94048a * Ignore missing manifest symlinks. 2012-01-03 12:59:00 +00:00
Eelco Dolstra 63227d434c * FreeBSD tar defaults to the tape device instead of stdout. 2012-01-03 12:18:41 +00:00
Eelco Dolstra 9b7df1ef00 * Forgot to add. 2012-01-03 09:19:40 +00:00
Eelco Dolstra 39d45a6b09 * Add a test for nix-channel. 
* Refactor the nix-channel unpacker a bit.
 2012-01-03 01:51:38 +00:00
Eelco Dolstra dadbb51d96 * Use Nix::Config. 2012-01-03 00:47:27 +00:00
Eelco Dolstra 48cea0d01e * Refactoring: Get rid of a few subdirectories in corepkgs/, and some 
other simplifications.
* Use <nix/...> to locate the corepkgs.  This allows them to be
  overriden through $NIX_PATH.
* Use bash's pipefail option in the NAR builder so that we don't need
  to create a temporary file.
 2012-01-03 00:16:29 +00:00
Eelco Dolstra 93e71e6ab6 * Follow our own coding conventions. 2011-12-30 17:39:03 +00:00
Eelco Dolstra f2d65c9c80 * Remove a redundant dot (Nicolas Pierron). 2011-12-30 17:31:58 +00:00
Eelco Dolstra 93b56acb2d * Support multiple outputs in nix-store (specifically the ‘--query’ 
and ‘--realise’ actions).
 2011-12-30 17:25:19 +00:00
Eelco Dolstra a71d02440b * Oops. 2011-12-30 17:13:25 +00:00
Eelco Dolstra 6f5e3326ce * Move topoSortPaths() out of gc.cc. 2011-12-30 15:02:50 +00:00
Eelco Dolstra b1004f40f7 * Reject a build if there is a cycle among the outputs. This is 
necessary because existing code assumes that the references graph is
  acyclic.
 2011-12-30 14:47:14 +00:00
Eelco Dolstra ed11b17b2e * Fix doc error. 2011-12-30 13:43:29 +00:00
Eelco Dolstra 254b3399ba * Sync with the trunk. 2011-12-30 13:08:14 +00:00
Eelco Dolstra 8c42a8c8ff * Make sure that lock files are cleaned up properly when building 
through the build hook.
 2011-12-25 16:38:37 +00:00
Eelco Dolstra 524fa8a4f1 * Oops. 2011-12-22 16:27:03 +00:00
Eelco Dolstra b33da599c5 * In the garbage collector, delete invalid paths before deleting 
unreachable paths.  This matters when using --max-freed etc.:
  unreachable paths could become reachable again, so it's nicer to
  keep them if there is "real" garbage to be deleted.  Also, don't use
  readDirectory() but read the Nix store and delete invalid paths in
  parallel.  This reduces GC latency on very large Nix stores.
 2011-12-22 15:55:53 +00:00
Eelco Dolstra 58d974336c * Drop unnecessary call to canonPath() (nixStore is already canonical). 2011-12-22 14:33:34 +00:00
Eelco Dolstra 66c99b0cf5 * ‘--disable-shared’ is no longer supported. Fortunately it's not 
needed for the coverage analysis.
 2011-12-22 10:58:27 +00:00
Eelco Dolstra 2aac7cd021 * Another case of lock file permissions being too liberal. 2011-12-21 19:17:45 +00:00
