Eelco Dolstra 98b07466fb * Better error checking of the data from the substituters. 2008-08-05 10:57:53 +00:00
Eelco Dolstra 339c142009 * Use optimistic profile locking for nix-env operations like `-i' and 
`-u'.  Instead of acquiring an exclusive lock on the profile for the
  entire duration of the operation, we just perform the operation
  optimistically (without an exclusive lock), and check at the end
  whether the profile changed while we were busy (i.e., the symlink
  target changed).  If so, the operation is restarted.  Restarting is
  generally cheap, since the build results are still in the Nix store.
  Most of the time, only the user environment has to be rebuilt.
 2008-08-04 16:21:45 +00:00
Eelco Dolstra a87b5256e2 * Fix the tests. 2008-08-04 16:16:49 +00:00
Eelco Dolstra 001b3f06ec * `nix-env --set': support --dry-run. 2008-08-04 14:58:50 +00:00
Eelco Dolstra 7592f48c83 * nix-build: `--dry-run' flag. 2008-08-04 13:46:01 +00:00
Eelco Dolstra a1d310b6b5 * `nix-store --realise': print what paths will be built/downloaded, 
just like nix-env.
* `nix-store --realise': --dry-run option.
 2008-08-04 13:44:46 +00:00
Eelco Dolstra 42043953c3 * Doh. 2008-08-04 13:15:47 +00:00
Eelco Dolstra 5adbb0aabe * build.cc: only use a substituter if it returns info for a path. 2008-08-04 13:15:35 +00:00
Eelco Dolstra 5b1052663a * Always show what paths we're going to build/download (as in 
--dry-run).  Maybe there should be an option to turn this on/off?
 2008-08-04 13:11:09 +00:00
Eelco Dolstra c4f98941ed * nix-env --dry-run: show the total size of the substituter 
downloads.
 2008-08-04 12:29:04 +00:00
Eelco Dolstra 03427e76f1 * querySubstitutablePathInfo: work properly when run via the daemon. 
* --dry-run: print the paths that we don't know how to build/substitute.
 2008-08-04 11:44:50 +00:00
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.
