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 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 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.
2003-04-09 13:03:00 +00:00
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.
