Eelco Dolstra 6fcdbcac20 * Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under
the Nix:: namespace.
2011-10-10 21:11:08 +00:00
Eelco Dolstra 365f3028dd * Use CamelCase for the Perl modules. 2010-12-05 17:50:29 +00:00
Eelco Dolstra f42a505ab7 * Add a script `nix-generate-patches'.
* Fix the binary patching test.
2010-12-05 17:36:02 +00:00
Eelco Dolstra d3bba0c2d8 * Move the patch generator into a module. 2010-11-29 15:26:28 +00:00
Eelco Dolstra bc1e478db1 * nix-copy-closure: start only one SSH connection to the server, or
recycle an already existing connection (using  OpenSSH's connection
  sharing feature).
2010-02-03 15:34:52 +00:00
Eelco Dolstra fa791116a3 * Get rid of nix-pack-closure / nix-unpack-closure, they're redundant. 2008-11-18 14:43:40 +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
Eelco Dolstra 660244f65f * Make sure that copy-from-other-stores.pl is built. 2008-07-23 09:38:38 +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.

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 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 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 69c8b5b8a7 * Install generate-patches into libexec. 2007-01-11 16:19:45 +00:00
Eelco Dolstra dcded7da47 * Don't try to do DNS lookups. 2006-07-21 12:28:25 +00:00
Eelco Dolstra ebcccbd358 * Added a tool to find additional roots for the garbage collector,
such as open files, current directories, mmaped files, etc.  This is
  inherently unportable, but it's easy to adapt this script to other
  platforms.  Currently we call `lsof' and try to read various bits in
  /proc/NNN.

  The goal is to prevent the garbage collector from removing store
  paths that are no longer reachable from a permanent root but that
  are still in use (for instance, after the user has done "nix-env -e"
  on a running program).
2006-07-19 16:49:59 +00:00
Eelco Dolstra 04cf72287b * This may be useful in the future. 2006-05-31 09:24:54 +00:00
Eelco Dolstra e4d4969ae9 * New tools nix-pack-closure and nix-unpack-closure. These provide a
useful way to transfer the closure of a store path to another
  machine.

  These commands provide functionality previously possible through
  `nix-push --copy'.  However, they are much more convenient in many
  situations (though possibly less efficient).
  
  Example:
  $ nix-pack-closure /nix/store/hj232g1r...-subversion-1.3.0 > svn.closure
  (on another machine:)
  $ nix-unpack-closure < svn.closure

  Note that Subversion is added to the store, but not installed into a
  user environment.  One should do `nix-env -i
  /nix/store/hj232g1r...-subversion-1.3.0' for that.

  Another example: copy the application Azureus to the machine
  `scratchy' through ssh:
  
  $ nix-pack-closure $(which azureus) | ssh scratchy nix-unpack-closure

Eelco Dolstra 9e50e648a4 * Doh! 2005-03-01 11:27:38 +00:00
Eelco Dolstra 8d364e5baa * Add missing file to dist. 2005-03-01 11:27:22 +00:00
Eelco Dolstra 2c4302dd7a * Added a disambiguation heuristic: if two components have the same
name but differ to much in sice (by more than a factor of 3), then
  never generate a patch.
2005-02-28 14:12:06 +00:00
Eelco Dolstra 3d1b2101cc * Place manifests in /nix/var/nix/manifests.
* Use the new patch downloader.
2004-12-20 16:38:50 +00:00
Eelco Dolstra 77970f8daf * Remove `prebuilts.conf' file, it's not like anybody was using it.
* Add /nix/var/nix/manifests directory.
2004-12-16 14:31:49 +00:00
Eelco Dolstra 3093af58a7 * A utility script `nix-build' that builds Nix expressions and prints
their output paths (and only that) on standard output.
2004-06-22 15:12:34 +00:00
Eelco Dolstra 21655a70f5 * Channels. These allow you to stay current with an evolving set of
Nix expressions.

  To subscribe to a channel (needs to be done only once):

    nix-channel --add \
      http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable

  This just adds the given URL to ~/.nix-channels (which can also be
  edited manually).

  To update from all channels:

    nix-channel --update

  This fetches the latest expressions and pulls cache manifests.  The
  default Nix expression (~/.nix-defexpr) is made to point to the
  conjunction of the expressions downloaded from all channels.

  So to update all installed derivations in the current user
  environment:

    nix-channel --update
    nix-env --upgrade '*'

  If you are really courageous, you can put this in a cronjob or
  something.

  You can subscribe to multiple channels.  It is not entirely clear
  what happens when there are name clashes between derivations from
  different channels.  From nix-env/main.cc it appears that the one
  with the lowest (highest?) hash will be used, which is pretty
  meaningless.

Eelco Dolstra 153429520a * Distributed the wrong file. 2004-04-06 15:55:27 +00:00
Eelco Dolstra 94175e978a * RPM spec file.
* Respect DESTDIR variable.
2003-12-30 20:09:00 +00:00
Eelco Dolstra 06c5a7075d * Refactoring: put the manifest-reading code in a separate file. 2003-12-05 11:25:38 +00:00
Eelco Dolstra e7ea52d3b3 * One-click installation :-)
The script nix-install-package takes a `Nix package file' (which
  contains one or more derivations, along with URLs of Nix caches),
  unpacks it, pulls the caches, and installs the derivations in the
  user's environment.

  For best results, associate the command `xterm -e
  /nix/bin/nix-install-package' with the MIME type
  `application/x-nix-package' and visit
  http://losser.st-lab.cs.uu.nl/~eelco/test/.
2003-11-24 11:11:40 +00:00
Eelco Dolstra ab0bc4999a * Maintain integrity of the substitute and successor mappings when
deleting a path in the store.
* Allow absolute paths in Nix expressions.
* Get nix-prefetch-url to work again.
* Various other fixes.
2003-11-22 18:45:56 +00:00
Eelco Dolstra e374dbf89b * A script `nix-prefetch-url' to fetch a URL, place it in the Nix
store, and print its hash.
2003-08-15 10:13:41 +00:00
Eelco Dolstra 39ce70025b * Incorporated Berkeley DB and ATerm into the source tree.
* `make dist'.
2003-07-23 15:53:34 +00:00
Eelco Dolstra ab350eafd2 * Generate nar.sh, fetchurl.sh. 2003-07-18 07:42:57 +00:00
Eelco Dolstra 9c620e4afa * Generate the scripts so that we can substitute the prefix
etc. correctly.
* Fixed nix-switch.
2003-07-13 18:58:03 +00:00
Eelco Dolstra 1d1c3691d2 * The policy-free derivate sharing now *almost* works. :-) For any
hash for which no local expansion is available, Nix can execute a
  `substitute' which should produce a path with such a hash.

  This is policy-free since Nix does not in any way specify how the
  substitute should work, i.e., it's an arbitrary (unnormalised)
  fstate expression.  For example, `nix-pull' registers substitutes
  that fetch Nix archives from the network (through `wget') and unpack
  them, but any other method is possible as well.  This is an
  improvement over the old Nix sharing scheme, which had a policy
  (fetching through `wget') built in.

  The sharing scheme doesn't work completely yet because successors
  from fstate rewriting have to be registered on the receiving side.
  Probably the whole successor stuff can be folded up into the
  substitute mechanism; this would be a nice simplification.
2003-07-10 15:11:48 +00:00
Eelco Dolstra d072485d28 * Get `nix-push' working again. It now uses Nix/Fix to create Nix
archives (using the package in corepkgs/nar).
* queryPathByHash -> expandHash, and it takes an argument specifying
  the target path (which may be empty).
* Install the core Fix packages in $prefix/share/fix.  TODO: bootstrap
  Nix and install Nix as a Fix package.
2003-07-10 13:41:28 +00:00
Eelco Dolstra f8d91f20e6 * Nix can now fetch prebuilts (and other files) from the network, iff
a mapping from the hash to a url has been registered through `nix
  regurl'.

* Bug fix in nix: don't pollute stdout when running tar, it made
  nix-switch barf.

* Bug fix in nix-push-prebuilts: don't create a subdirectory on the
  target when rsync'ing.
2003-05-26 09:44:18 +00:00
Eelco Dolstra 7dd91d3779 * Prebuilt package sharing. We allow transparent binary deployment by
sharing package directories (i.e., the result of building a Nix
  descriptor).

  `nix-pull-prebuilts' obtains a list of all known prebuilts by
  consulting the paths and URLs specified in
  $prefix/etc/nix/prebuilts.conf.  The mappings ($pkghash,
  $prebuilthash) and ($prebuilthash, $location) are registered with
  Nix so that it can use the prebuilt with hash $prebuilthash when
  installing a package with hash $pkghash by downloading and unpacking
  $location.

  `nix-push-prebuilts' creates prebuilts for all packages for which no
  prebuilt is known to exist.  It can then optionally upload these
  to the network through rsync.

  `nix-[pull|push]-prebuilts' just provide a policy.  Nix provides the
  mechanism through the `nix [export|regprebuilt|regurl]' commands.
2003-05-25 22:42:19 +00:00
Eelco Dolstra f7526febe4 * A garbage collector for installed packages. nix-collect-garbage
doesn't actually delete any packages, it just prints their
  descriptor hashes.  So we can do

    nix info $(nix-collect-garbage)

  to print out the ids of the packages that would be deleted, and

    nix delpkg $(nix-collect-garbage)

  to actually delete them.
2003-04-09 13:03:00 +00:00
Eelco Dolstra aa8fda4b54 * We no longer use nix-populate standalone, rather we use it as a
build action for `system' packages (like system.fix) that have
  dependencies on all packages we want to activate.

  So the command sequence to switch to a new activation configuration
  of the system would be:

    $ fix -i .../fixdescriptors/system.fix
    ...
    system.fix -> 89cf4713b37cc66989304abeb9ea189f

    $ nix-switch 89cf4713b37cc66989304abeb9ea189f

* A nix-profile.sh script that can be included in .bashrc.
