Eelco Dolstra 9fd9c4c635 * Support multiple system types per remote machine, e.g. a machine
list like

    root@example.org x86_64-linux /root/.ssh/id_buildfarm 1
    root@example.org i686-darwin  /root/.ssh/id_buildfarm 1

  This is possible when the Nix installation on example.org itself has
  remote builds enabled.

Eelco Dolstra f8713e1287 * Dirty hack to make nix-push work properly on derivations: the
derivation should be a source rather than a derivation dependency of
  the call to the NAR derivation.  Otherwise the derivation (and all
  its dependencies) will be built as a side-effect, which may not even
  succeed.

Eelco Dolstra 4213b8d8ec * Urgh. 2008-11-20 15:44:59 +00:00
Eelco Dolstra aab530e971 * Primop builtins.storePath for declaring a store path as a
dependency.  `storePath /nix/store/bla' gives exactly the same
  result as `toPath /nix/store/bla', except that the former includes
  /nix/store/bla in the dependency context of the string.

  Useful in some generated Nix expressions like nix-push, which now
  finally does the right thing wrt distributed builds.  (Previously
  the path to be packed wasn't an explicit dependency, so it wouldn't
  be copied to the remote machine.)

Eelco Dolstra fa791116a3 * Get rid of nix-pack-closure / nix-unpack-closure, they're redundant. 2008-11-18 14:43:40 +00:00
Eelco Dolstra 2b2aa8a820 * Doh. 2008-09-08 11:02:15 +00:00
Michael Raskin 2a01d06da6 Added nix-http-export.cgi to extra distributed scripts; so it can be installed from releases, not only from SVN. 2008-08-29 08:34:38 +00:00
Michael Raskin b455c4c45c Updates to nix-reduce-build
Common code in local build package sources refactored out in a function; before building the real set of derivations needed is found (slightly slower for only one build strategy, but less garbage on output and better performance for multiple build strategies).

Now you have full choice of best-effort build regardless of method (substituters or actual build), using substituters, building only fixed derivations (should get you all the downloads) and local build without even trying substituters. 

Some minor fix in the help text about behavior with no package sources.

Eelco Dolstra 7592f48c83 * nix-build: `--dry-run' flag. 2008-08-04 13:46:01 +00:00
Eelco Dolstra 42043953c3 * Doh. 2008-08-04 13:15:47 +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 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 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
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
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
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 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 f106868110 * Cleanup. 2008-03-20 10:16:36 +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 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).
2007-11-16 16:15:26 +00:00
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.
2007-11-05 18:12:29 +00:00
Eelco Dolstra f8ed2e64a5 2007-10-22 12:05:18 +00:00
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).
2007-10-09 22:14:27 +00:00
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".)
2007-09-17 16:08:24 +00:00
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.)
2007-08-22 14:52:22 +00:00
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.
2006-12-08 15:44:00 +00:00
Eelco Dolstra d941186289 * Show more progress. 2006-11-18 19:03:45 +00:00
Eelco Dolstra b3f916995a * Oops, `nix-build --no-out-link' was broken. 2006-10-31 18:45:17 +00:00
Eelco Dolstra 8d17265ac4 * Don't use EPSV. 2006-10-28 22:07:09 +00:00
Eelco Dolstra b3d3700e11 * nix-build: check the exit status of `nix-store -r'. 2006-10-19 17:30:09 +00:00
Eelco Dolstra 2a535689fe * Reduce the maximum archive size for patch generation to 100 MB to
prevent trashing on nix.cs.uu.nl.
2006-10-12 20:13:29 +00:00
Eelco Dolstra d98f750fd8 * tmpnam() -> File::Temp::tempdir(). 2006-10-04 18:58:11 +00:00
Eelco Dolstra 3632019b73 * Quick hack to let nix-install-package set the package name properly
(e.g., "java-front-0.9pre15899" instead of "java-front";
  particularly important when doing upgrades later on).
2006-09-25 14:00:59 +00:00
Eelco Dolstra d43565c3e8 * In `nix-channel --update', skip manifests that assume a Nix store at
a different location than the user's.  This makes channels usable as
  a source deployment mechanism for people who install Nix under
  non-standard prefixes.  (NIX-57)
2006-09-25 11:11:16 +00:00
Eelco Dolstra 68ae953d8a * Clean up calls to system(). 2006-09-25 10:44:27 +00:00
Eelco Dolstra 76c9710091 * Use builtins.toPath. 2006-09-25 10:29:25 +00:00
Eelco Dolstra 0bd5eb71a0 * `nix-install-package --url': install from a URL (NIX-12).
* `nix-install-package --help' (NIX-9).
* `nix-install-package --non-interactive': don't prompt or pause.
* Tests for nix-install-package.
* Security fixes: filter the values obtained from the nixpkg.
2006-09-21 18:54:08 +00:00
Eelco Dolstra ee5040421f * Try konsole and gnome-terminal in addition to xterm. 2006-09-21 11:29:14 +00:00
Eelco Dolstra 1b804f88e4 * Absolute path to rm (NIX-51).
* Don't hardcore /nix/bin and /nix/store.
2006-09-20 16:23:14 +00:00
Eelco Dolstra 947e645789 * Hide warnings about a missing "lsof" (NIX-54). 2006-09-20 15:14:19 +00:00
Eelco Dolstra a060adf165 * Use paths, not strings, when calling the function that generates
NARs.  Fixes the impurity of nix-push (NIX-21).
* Better help.
2006-09-20 15:04:04 +00:00
Eelco Dolstra 7dd342e482 * Doh. 2006-09-19 16:40:22 +00:00
Eelco Dolstra ee6cf99660 * Doh! Of course we have to take execute permission into account.
* Restore the mtime on modified directories.
2006-09-19 16:14:15 +00:00
Eelco Dolstra 6dbed1bf38 * `optimise-store.pl' reduces disk space consumption by hard-linking
all identitical files in the Nix store to each other.  (Previously
  it only computed the size that would be saved by doing so.)
2006-09-19 14:58:35 +00:00
Eelco Dolstra 07cec27848 * Cleanups. 2006-09-19 14:27:28 +00:00
Eelco Dolstra 9488ae7357 * `show-duplication.pl', a small utility that shows the amount of
package duplication present in (e.g.) a profile.  It shows the
  number of instances of each package in a closure, along with the
  size in bytes of each instance as well as the "waste" (the
  difference between the sum of the sizes of all instances and the
  average size).

Eelco Dolstra 2e210b2387 * Convenience option `nix-collect-garbage -d' (--delete-old): removes
old generations of *all* profiles in /nix/var/nix/profiles, then
  runs the garbage collector.  Quick way to get rid of all old stuff.
  Of course, one cannot roll back to earlier points in time after
  this.
