Michael Raskin b3c26180e3 Updates to nix-reduce-build: only realize fixed derivations if user asks so, or only use substituters. Oh, and add possibility to use : for things like /etc/nixos/nixpkgs:-A:gnused 2008-08-02 16:43:25 +00:00
Eelco Dolstra 3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.
2008-08-02 12:54:35 +00:00
Eelco Dolstra fc691e1cbd * Print a better error message when a non-derivation attribute set is
coerced to a string.
2008-07-24 14:52:25 +00:00
Eelco Dolstra 096198d11f * A quick hack to make nix-prefetch-url support mirror:// URLs. It
requires that $NIXPKGS_ALL points at a Nixpkgs tree.
2008-07-23 16:02:58 +00:00
Eelco Dolstra 660244f65f * Make sure that copy-from-other-stores.pl is built. 2008-07-23 09:38:38 +00:00
Eelco Dolstra e139d7fc68 * Fix the tests. 2008-07-18 20:03:12 +00:00
Eelco Dolstra 989176c56e * Allow read-only access to the store (e.g., non-root users on NixOS
can do operations like "nix-store -qR <path>" even without the Nix
  daemon).
2008-07-18 15:34:46 +00:00
Eelco Dolstra 8bc591a6f0 * Use the copy-from-other-stores substituter by default. Of course,
it only does something if $NIX_OTHER_STORES (not really a good
  name...) is set.
* Do globbing on the elements of $NIX_OTHER_STORES.  E.g. you could
  set it to /mnts/*/nix or something.
* Install substituters in libexec/nix/substituters.
2008-07-18 13:05:10 +00:00
Eelco Dolstra 15f39aba8c * Quick prototype of a substituter that copies paths from other Nix
stores (typically remote Nix stores mounted via e.g. NFS, or the Nix
  store on the NixOS installation CD).  Example use:

  $ sshfs foo@example.org:/ /mnt
  $ NIX_OTHER_STORES=/mnt/nix \
    NIX_SUBSTITUTERS=.../copy-from-other-stores.pl \
    nix-env -i foo

  This will be especially useful for the installation CD since it
  doesn't require a manifest for the CD contents.
2008-07-12 18:58:24 +00:00
Eelco Dolstra 7cd88b1dec * Generalised the dependencyClosure primop to builtins.genericClosure,
which is hopefully more useful.
* New primops: length, mul, div.
2008-07-11 13:29:04 +00:00
Eelco Dolstra d567baabbd * Export the nix-env derivation name parsing and version comparison
logic through the `parseDrvName' and `compareVersions' primops.
  This will allow expressions to easily check whether some dependency
  is a specific needed version or falls in some version range.  See
  tests/lang/eval-okay-versions.nix for examples.
2008-07-01 10:10:32 +00:00
Eelco Dolstra b3b0b2a29e * `make ext-clean': remove the bzip2 build. 2008-06-23 13:52:28 +00:00
Eelco Dolstra 6c8641a542 2008-06-18 19:17:05 +00:00
Eelco Dolstra 5af84139a8 * --max-freed: support values >= 4 GB. 2008-06-18 15:20:33 +00:00
Eelco Dolstra d3aa183beb * Garbage collector: option `--max-freed' to stop after at least N
bytes have been freed, `--max-links' to stop when the Nix store
  directory has fewer than N hard links (the latter being important
  for very large Nix stores on filesystems with a 32000 subdirectories
  limit).
2008-06-18 14:20:16 +00:00
Eelco Dolstra a8f3b02092 * `nix-store --optimise': handle files with >= 32000 hard links.
(There can easily be more than 32000 occurrences of the empty file.)
2008-06-18 14:13:00 +00:00
Eelco Dolstra a72709afd8 * Some refactoring: put the GC options / results in separate structs.
* The garbage collector now also prints the number of blocks freed.
2008-06-18 09:34:17 +00:00
Eelco Dolstra 934c58aa38 * Use bzip2 1.0.5. 2008-06-17 08:12:12 +00:00
Eelco Dolstra ee8f15930d * Test instrumentation. 2008-06-15 15:10:03 +00:00
Eelco Dolstra f351834f77 * nix-worker: clean up the temporary root for the worker processes
in /nix/var/nix/temproots.
2008-06-14 16:03:02 +00:00
Eelco Dolstra 94fd46fa1c * Note. 2008-06-14 16:02:31 +00:00
Michael Raskin 955b8841cd Also trying to build derivers in case we cannot get substituters 2008-06-14 08:48:40 +00:00
Michael Raskin 18e27629d3 Added local best-effort builds (i.e. one failure does not ruin all packages you would like to see built) 2008-06-14 08:30:35 +00:00
Eelco Dolstra 826b271d9a * Garbage collector: don't do a complete topological sort of the Nix
store under the reference relation, since that means that the
  garbage collector will need a long time to start deleting paths.
  Instead just delete the referrers of a path first.
2008-06-13 18:25:24 +00:00
Eelco Dolstra 30c9f909b2 * Print some progress info during the early GC stages. 2008-06-13 17:21:20 +00:00
Michael Raskin 194c66eeeb Stupid error in script 2008-06-13 14:34:19 +00:00
Michael Raskin f903d86740 OK, I will believe that fix does no worse.. 2008-06-13 13:53:14 +00:00
Michael Raskin ce85b55cf0 Updated help text 2008-06-12 17:45:38 +00:00
Michael Raskin 4532e4b90d Added verbosity for nix-reduce-build 2008-06-12 16:26:53 +00:00
Eelco Dolstra 2818b7cee6 * Updated some URLs. 2008-06-11 15:39:38 +00:00
Eelco Dolstra 997b95a4af * Fixed compatibility with old versions of "wc" that print whitespace
before the count.
2008-06-10 10:08:15 +00:00
Eelco Dolstra b0e92f6d47 * Merged the no-bdb branch (-r10900:HEAD
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-09 13:52:45 +00:00
Eelco Dolstra 4ed01ed791 * Updated some URLs (did this a long time ago but forgot to
commit...).
2008-06-09 13:42:13 +00:00
Sander van der Burg c41a3ec3a9 First attempt to update Nix SDF grammar to match the actual bison grammar 2008-06-04 14:36:46 +00:00
Eelco Dolstra bd955e15e1 * GCC 4.3.0 (Fedora 9) compatibility fixes. Reported by Gour and
Armijn Hemel.
2008-05-21 11:17:31 +00:00
Michael Raskin 9819bb20da Added support for file:// archive (.nar.gz) repositories to nix-reduce-build. /tmp/nix-export created by nix-http-export.cgi is OK. 2008-05-11 15:54:30 +00:00
Michael Raskin b4bc8b7616 --proxy=proxy:3128 2008-05-07 14:18:28 +00:00
Michael Raskin b1e321d6ce Added http alternative transport for nix-reduce-build 2008-04-29 04:03:54 +00:00
Eelco Dolstra 658816ddc9 * Make really sure that we use bash. The line
NEED_PROG(shell, bash)

  actually uses the content of $shell if set, which often points at
  /bin/sh.
2008-04-10 09:54:23 +00:00
Eelco Dolstra 72034ab35d * sockaddr_un doesn't allow path names of more than 108 characters.
This isn't usually a problem, except that it causes tests to fail
  when performed in a directory with a very long path name.  So chdir
  to the socket directory and use a relative path name.
2008-04-09 05:57:01 +00:00
Eelco Dolstra f8985d195e * Fix for NIX-101 (should use an absolute path for call to nix-hash). 2008-03-28 17:52:33 +00:00
Eelco Dolstra 329025253d * Use /tmp/nix-build-<drvpath>-<counter> instead of
/tmp/nix-<pid>-<counter> for temporary build directories.  This
  increases purity a bit: many packages store the temporary build path
  in their output, causing (generally unimportant) binary differences.
2008-03-27 13:45:17 +00:00
Eelco Dolstra 5bb08db55b * Updated URL. 2008-03-21 14:57:16 +00:00
Eelco Dolstra 98968fbb63 * Disable the don't-run-as-root sanity check because it breaks RPM
builds (which are done as root...).
2008-03-20 18:15:20 +00:00
Eelco Dolstra 2f1e2cf632 * Note that the SDF grammar isn't used. 2008-03-20 14:59:33 +00:00
Eelco Dolstra f106868110 * Cleanup. 2008-03-20 10:16:36 +00:00
Eelco Dolstra f789ea1d09 * A transaction is unnecessary since the path cannot be
garbage-collected (it's a temporary root).
2008-03-01 21:05:33 +00:00
Eelco Dolstra d7caac3e81 * Don't install nix-reduce-build by default yet please, I first want
to understand better what it does...
2008-02-28 21:27:47 +00:00
Michael Raskin 11d512e7a8 Added nix-reduce-build. You point it to some path you want to build and it fetches whatever it can from specified computers via nix-copy-closure. NOTE: You do want to set up RSA keys or ssh-agent or something... You really do want it. It will run separate ssh instances insane number of times. 2008-02-27 21:26:47 +00:00
Eelco Dolstra 0a84137c45 * checkVarDefs: don't check in closed terms, which don't have
undefined variables by definition.  This matters for the
  implementation of "with", which does a call to checkVarDefs to see
  if the body of the with has no undefined variables.  (It can't be
  checked at parse time because you don't know which variables are in
  the "with" attribute set.)  If we check closed terms, then we check
  not just the with body but also the substituted terms, which are
  typically very large.  This is the cause of the poor nix-env
  performance on Nixpkgs lately.  It didn't happen earlier because
  "with" wasn't used very often in the past.

  This fix improves nix-env performance roughly 60x on current Nixpkgs.
  nix-env -qa is down from 29.3s to 0.5s on my laptop, and nix-env -qa
  --out-path is down from 229s to 3.39s.  Not bad for a 1-line fix :-)
