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.

Eelco Dolstra 13176d74cc * Updated Fix descriptors to reflect the new Fix abstract syntax. 2003-05-25 22:43:33 +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.

Eelco Dolstra 0ef4b6d0f8 * Cleaned up the semantics of Fix expressions.
* Conditionals and variables in Fix expressions.  This allows, e.g.,

    Descr(
    [ Bind("pkgId", "subversion-0.21.0")

    , Bind("httpsClient", Bool(True))
    , Bind("httpServer", Bool(True))

    , Bind("ssl", If(Var("httpsClient"), Fix("./openssl-0.9.7b.fix"), ""))

    , Bind("httpd", If(Var("httpServer"), Fix("./httpd-2.0.45.fix"), ""))
    ...
    ])

  which introduces domain feature variables httpsClient and httpServer
  (i.e., whether Subversion is built with https client and webdav
  server support); the values of the variables influences package
  dependencies and the build scripts.

  The next step is to allow that packages can express constraints on
  each other.  E.g., StrategoXT is dependent on an ATerm library with
  the "gcc" variant enabled.  In fact, this may cause several
  Nix instantiations to be created from a single Fix descriptor.  If
  possible, Fix should try to find the least set of instantiations
  that obeys the constraints.

Eelco Dolstra d6d930a975 * Bug fix: deleting the old links didn't work properly. 2003-04-25 15:20:05 +00:00
Eelco Dolstra fcc5ae151b * Remove build directory from a package directory after building it. 2003-04-25 15:01:15 +00:00
Eelco Dolstra 76205df09c * Removed old Nix descriptors. 2003-04-24 11:45:23 +00:00
Eelco Dolstra 243370bc52 * nix-switch now removes the link to the previously activated system
package as a root of the garbage collector, unless `--keep' is
  specified.
2003-04-24 11:43:11 +00:00
Eelco Dolstra 24b3d0759e * File removed. 2003-04-24 11:41:50 +00:00
Eelco Dolstra 9713e8577f * getpkg, delpkg, and so on now accept multiple arguments. 2003-04-24 11:41:24 +00:00
Eelco Dolstra 49e0d743d7 * Fix descriptors for Pan and its dependencies. 2003-04-23 21:21:06 +00:00
Eelco Dolstra f546e0cda4 * Fix descriptor for Subversion 0.21.0. 2003-04-23 09:02:53 +00:00
Eelco Dolstra 6faa154c89 * Add "... || exit 1" to every command to catch failure. 2003-04-23 07:23:01 +00:00
Eelco Dolstra e59c3246b9 * Redirect stdout to stderr when executing the build script. 2003-04-23 07:21:57 +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.

Eelco Dolstra 30a6122f80 * When we activate a descriptor in nix-switch, remember its hash.
This allows us to find out all `live' packages on the system by
  doing

    nix closure $(cat /nix/var/nix/links/*.hash)

  which will print out the activated configurations and all packages
  referenced by them.  We could then garbage collect unused packages
  by deleting the difference between `nix listinst' and the set
  returned by `nix closure ...'.
2003-04-09 12:46:44 +00:00
Eelco Dolstra b762f4df7f * In `fix --instantiate', only print out the hashes of the Nix
descriptors generated out of Fix descriptors specified on the
  command line.  This allows us to say:

    nix-switch $(fix -i ./test/fixdescriptors/system.fix)
2003-04-09 12:37:49 +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.

Eelco Dolstra 0d2b24cdd1 * `Fix' is a high-level descriptor instantiator for Nix. It replaces
nix-instantiate.
2003-04-08 12:00:51 +00:00

Eelco Dolstra ced20f187e * Nix descriptor for Subversion. 2003-03-31 14:28:15 +00:00
Eelco Dolstra 31f177ef0a * Check for collissions. 2003-03-28 16:27:23 +00:00
Eelco Dolstra 278ea4097e * Don't fork in `nix run'. 2003-03-28 10:33:34 +00:00
Eelco Dolstra f915f77349 * Allow arguments to be passed to programs in `nix run'. 2003-03-28 09:53:22 +00:00
Eelco Dolstra 0f40a560ca * Added a script nix-activate which builds a list of "activated"
packages (i.e., the packages that should appear in the user's $PATH,
  and so on).  Based on this list, the script nix-populate creates a
  hierarchy of symlinks to the relevant files in those packages (e.g.,
  for pkg/bin and pkg/lib).  

  A nice property of nix-populate is that on each run it creates a
  *new* tree, rather than updating the old one.  It then atomically
  switches over to the new tree.  This allows atomic upgrades or
  rollbacks on the set of activated packages.
2003-03-25 16:36:25 +00:00
Eelco Dolstra 3f1a1457e9 * Integrate hash into instantiated descriptor file names.
* Use MD5::Digest.
2003-03-25 11:39:51 +00:00
Eelco Dolstra 73c53935d0 * For efficiency: md5 integrated into nix.
* Command `nix ensure' which is like `nix getpkg' except that if the
  has refers to a run action it will just ensure that the imports are
  there.
* Command `nix closure' to print out the closure of the set of
  descriptors under the import relation, starting at a set of roots.
  This can be used for garbage collection (e.g., given a list of
  `activated' packages, we can delete all packages not reachable from
  those).
* Command `nix graph' to print out a Dot graph of the dependency
  graph.
* `nix-addroot' adds a root for the (unimplemented) garbage collector.

Eelco Dolstra eeab86e0ac * Typo fix. 2003-03-24 16:43:52 +00:00
Eelco Dolstra 2dc84e5569 * Descriptors now have a "system" field specifying the platform that
the build or run action should be perfomed on.  This ensures that
  descriptors have different hashes on different platforms.
2003-03-24 12:49:40 +00:00
Eelco Dolstra 9d2f128252 * Refactoring. 2003-03-24 11:50:20 +00:00
Eelco Dolstra 8d682ba551 * A descriptor for running the Pan newsreader.
* Added descriptors for gtkspell and its support package pspell.
  Gtkspell is an optional dependency of Pan, so we should add the
  ability to nix-instantiate to instantiate variants of a package
  based on a selection of features.
2003-03-23 23:28:28 +00:00
Eelco Dolstra 20d165c344 * A command to run programs in Nix packages, that is, to execute a run
action.  Run actions are described by uniquely hashed descriptors,
  just like build actions.  Therefore run actions can have
  dependencies, but these need not be the same as the build time
  dependencies (e.g., at runtime we can link against a different
  version of a dynamic library).  Example:

    nix run 31d6bf4c171282367065e0deecd7c579

  will run the Pan 0.13.91 newsreader with gtkspell support.

Eelco Dolstra 4c43711810 * Descriptor templates for the Pan newsreader and all its
dependencies.
2003-03-20 22:25:01 +00:00
Eelco Dolstra cadc3852e4 * nix-instantiate now instantiantes the closure of the set of
descriptor templates under the import relation.  I.e., we can now
  say:

    nix-instantiate outdir foo.nix

  which will create descriptors for foo.nix and all imported packages
  in outdir/.

Eelco Dolstra f7a98e081d * Various updates. 2003-03-20 16:53:00 +00:00
