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 de012e76e2 * Don't use "store expression", it's obsolete. 2007-12-30 23:35:45 +00:00
Eelco Dolstra c370755583 * Flag `--no-build-hook' to disable distributed builds.
* queryDeriver in daemon mode: don't barf if the other side returns an
  empty string (which means there is no deriver).

Eelco Dolstra 6784b14241 * nix-build: pass --argstr to nix-instantiate. 2007-11-15 16:52:40 +00:00
Eelco Dolstra ca210d2a58 * Doh! 2007-11-15 15:33:30 +00:00
Eelco Dolstra bfec245efa * Add build-remote.pl to the Nix distribution. 2007-11-15 14:28:08 +00:00
Eelco Dolstra 5b74a59570 * nix-prefetch-url: don't fail if /tmp/nix-prefetch-url-<pid> exists,
instead use a counter just like we do for temporary build
  directories.

Eelco Dolstra a8629de827 * New command `nix-store --optimise' to reduce Nix store disk space
usage by finding identical files in the store and hard-linking them
  to each other.  It typically reduces the size of the store by
  something like 25-35%.  This is what the optimise-store.pl script
  did, but the new command is faster and more correct (it's safe wrt
  garbage collection and concurrent builds).

Eelco Dolstra 26f981c2e5 * Remove garbage. 2007-09-18 08:26:55 +00:00
Eelco Dolstra 055608227f * nix-env: allow ~/.nix-defexpr to be a directory. If it is, then the
Nix expressions in that directory are combined into an attribute set
  {file1 = import file1; file2 = import file2; ...}, i.e. each Nix
  expression is an attribute with the file name as the attribute
  name.  Also recurses into directories.

* nix-env: removed the "--import" (-I) option which set the
  ~/.nix-defexpr symlink.

* nix-channel: don't use "nix-env --import", instead symlink
  ~/.nix-defexpr/channels.  So finally nix-channel --update doesn't
  override any default Nix expressions but combines with them.

  This means that you can have (say) a local Nixpkgs SVN tree and use
  it as a default for nix-env:

  $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn

  and be subscribed to channels (including Nixpkgs) at the same time.
  (If there is any ambiguity, the -A flag can be used to
  disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)

Eelco Dolstra 9441550acb * nix-push / generate-patches: bzip the manifest. 2007-09-04 15:38:09 +00:00
Eelco Dolstra 7d5836b34d * nix-channel: supports users who don't have write permission to the
manifests directory.  In that case, we don't do a nix-pull, so the
  user gets pure source deployment.

  The directory /nix/var/nix/gcroots/per-user/$USER should be
  writable.  (It's created automatically if
  /nix/var/nix/gcroots/per-user is writable, e.g. if it has 1777
  permission.)

Eelco Dolstra dbc0170ed9 * Show errors in nix-prefetch-url. 2007-08-15 09:24:06 +00:00
Eelco Dolstra ffa1c61cd5 * Fix the tests. 2007-08-14 13:15:59 +00:00
Eelco Dolstra 9e975458b4 * Get rid of the substitutes database table (NIX-47). Instead, if we
need any info on substitutable paths, we just call the substituters
  (such as download-using-manifests.pl) directly.  This means that
  it's no longer necessary for nix-pull to register substitutes or for
  nix-channel to clear them, which makes those operations much faster
  (NIX-95).  Also, we don't have to worry about keeping nix-pull
  manifests (in /nix/var/nix/manifests) and the database in sync with
  each other.

  The downside is that there is some overhead in calling an external
  program to get the substitutes info.  For instance, "nix-env -qas"
  takes a bit longer.

  Abolishing the substitutes table also makes the logic in
  local-store.cc simpler, as we don't need to store info for invalid
  paths.  On the downside, you cannot do things like "nix-store -qR"
  on a substitutable but invalid path (but nobody did that anyway).

* Never catch interrupts (the Interrupted exception).
2007-08-12 00:29:28 +00:00
Eelco Dolstra 4695f4edd6 * nix-pull: support bzipped manifests: when doing a nix-pull on $url,
try $url.bz2 first.
2007-08-10 01:42:00 +00:00
Eelco Dolstra 911bc01454 * Enable nix-prefetch-url caching in nix-channel. 2007-08-10 00:28:44 +00:00
Eelco Dolstra 5e52df18fe * Don't rely on /dev/stdin. 2007-08-10 00:22:21 +00:00
Eelco Dolstra c5e934dcc9 * nix-pull: using nix-prefetch-url (so that we get caching for free),
and store the manifests in the Nix store.  (So now
  /nix/var/nix/manifests/ just contains symlinks to the store and is
  searched for GC roots.)
2007-08-09 23:52:53 +00:00
Eelco Dolstra f881f7a017 * nix-prefetch-url: support caching. If the environment variable
NIX_DOWNLOAD_CACHE is set, then nix-prefetch-url will store the hash
  and timestamp of downloaded files in the directory
  $NIX_DOWNLOAD_CACHE.  This allows it to figure out if the file is
  still in the Nix store.
2007-08-09 23:16:44 +00:00
Eelco Dolstra 9bff7ad728 * Check against creation of GC roots in the store. Those roots don't
work, because findRoots() stops when it encounters a symlink to the
  store.  And of course the store is supposed to be read-only.
2007-06-11 11:36:22 +00:00
Eelco Dolstra f3ebd03bb1 * Remove debug statement. 2007-06-04 12:03:33 +00:00
Eelco Dolstra 34d4c9388b 2007-05-02 16:06:04 +00:00
Eelco Dolstra 93aefd9fc0 * Give unpacked channels more sensible names than 0, 1, ... They now
get the basename of the channel URL (e.g., nixpkgs-unstable).  The
  top-level Nix expression of the channel is now an attribute set, the
  attributes of which are the individual channels (e.g.,
  {nixpkgs_unstable = ...; strategoxt_unstable = ...}).  This makes
  attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible,
  e.g., "nix-env -iA nixpkgs_unstable.subversion".
2007-05-01 23:16:38 +00:00
Eelco Dolstra 4caca58ff7 * Make the maximum patch size configurable. 2007-03-30 09:01:05 +00:00
Eelco Dolstra efd31139df * Forgot a @bindir@. 2007-03-27 09:53:58 +00:00
Eelco Dolstra d303b389a9 * `nix-copy-closure --from': copy from a remote machine instead of to
a remote machine.
2007-03-26 21:05:17 +00:00
Eelco Dolstra 7edd2e2cd2 * Refactoring. 2007-03-26 20:49:22 +00:00
Eelco Dolstra a8ea4cbcc8 * Scan /proc/sys/kernel/modprobe for roots to prevent the kernel
modules for the running kernel from being garbage-collected.  Idem
  for /proc/sys/kernel/fbsplash.
2007-03-20 11:13:15 +00:00
Eelco Dolstra eb2dd4815c * Remove old generations in all directories under
/nix/var/nix/profiles, not just in that directory itself.  (NixOS
  puts profiles in /nix/var/nix/profiles/per-user.)
2007-03-13 11:30:57 +00:00
Eelco Dolstra df0283ae86 * Get rid of those stupid --login tricks, it's the responsibility of
the remote system to make sure that Nix is in the $PATH.
2007-03-01 13:55:47 +00:00
Eelco Dolstra 30394a4f3f * sh -> bash. 2007-03-01 13:49:20 +00:00
Eelco Dolstra 363e307fd3 * Error message to stdout. 2007-02-26 23:32:10 +00:00
Eelco Dolstra fa2be32034 * nix-copy-closure: force a login shell on the remote machine to make
sure that nix-store is in the PATH.
* nix-copy-closure: option --gzip to compress data.
2007-02-22 16:42:01 +00:00
Eelco Dolstra 4c5e6d1a2f * nix-copy-closure: option --sign.
* nix-copy-closure: set SSH options through NIX_SSHOPTS..
2007-02-22 15:48:20 +00:00
Eelco Dolstra 024a8ed382 * New command `nix-copy-closure' to copy a closure to a Nix store on
another machine through ssh.  E.g.,

    $ nix-copy-closure xyzzy $(which svn)

  copies the closure of Subversion to machine `xyzzy'.  This is like
  `nix-pack-closure $(which svn) | ssh xyzzy', but it's much more
  efficient since it only copies those paths that are missing on the
  target machine.
2007-02-21 23:14:53 +00:00
Eelco Dolstra 8181a1c3bb * Close the file - just in case. 2007-02-20 22:49:08 +00:00
Eelco Dolstra bae75ca5a1 * New kind of manifest object: "localPath", which denotes that a store
path can be created by copying it from another location in the file
  system.  This is useful in the NixOS installation.
2007-01-23 16:50:19 +00:00
Eelco Dolstra 36d9258c0d * Successors have been gone for ages. 2007-01-23 16:05:59 +00:00
Eelco Dolstra 7bc30e1ca8 * nix-prefetch-url: change the default hash to SHA-256 (in base-32). 2007-01-22 09:53:36 +00:00
Eelco Dolstra afe23b5f38 * nix-pack-closure: store the top-level store paths in the closure.
* nix-unpack-closure: extract the top-level paths from the closure and
  print them on stdout.  This allows them to be installed, e.g.,
  "nix-env -i $(nix-unpack-closure)".  (NIX-64)
2007-01-13 19:50:42 +00:00
Eelco Dolstra 215505bb46 * Removed chroot support. 2007-01-13 17:54:01 +00:00
Eelco Dolstra 1b7840b949 2007-01-11 19:28:28 +00:00
Eelco Dolstra 69c8b5b8a7 * Install generate-patches into libexec. 2007-01-11 16:19:45 +00:00
Eelco Dolstra 1f3722bd4a * Reject patches that are larger than a certain fraction of the full archive
(currently 60%).  Large patches aren't very economical.
2007-01-08 15:32:15 +00:00
Eelco Dolstra 50bdec410a * Huge speedup in patch propagation (20 minutes or so to 3 seconds). 2007-01-08 15:17:18 +00:00
Eelco Dolstra cafaceb707 * Handle weird cases when the server redirects us while setting a cookie. 2006-12-15 21:27:26 +00:00
Eelco Dolstra 9dbfe242e3 * Kill a build if it has gone for more than a certain number of
seconds without producing output on stdout or stderr (NIX-65).  This
  timeout can be specified using the `--max-silent-time' option or the
  `build-max-silent-time' configuration setting.  The default is
  infinity (0).

* Fix a tricky race condition: if we kill the build user before the
  child has done its setuid() to the build user uid, then it won't be
  killed, and we'll potentially lock up in pid.wait().  So also send a
  conventional kill to the child.

Eelco Dolstra d941186289 * Show more progress. 2006-11-18 19:03:45 +00:00
