Michel Alexandre Salim 6a214f3e06 Update nix profile: - incorporate NixOS's configuration so that nix is usable by normal users - install as a data file, not a program file 2012-05-31 08:59:36 -04:00
Eelco Dolstra 6814b1dfa1 Generate binary tarballs for installing Nix
For several platforms we don't currently have "native" Nix packages
(e.g. Mac OS X and FreeBSD).  This provides the next best thing: a
tarball containing the closure of Nix, plus a simple script
"nix-finish-install" that initialises the Nix database, registers the
paths in the closure as valid, and runs "nix-env -i /path/to/nix" to
initialise the user profile.

The tarball must be unpacked in the root directory.  It creates
/nix/store/... and /usr/bin/nix-finish-install.  Typical installation
is as follows:

  $ cd /
  $ tar xvf /path/to/nix-1.1pre1234_abcdef-x86_64-linux.tar.bz2
  $ nix-finish-install
  (if necessary add ~/.nix-profile/etc/profile.d/nix.sh to the shell
  login scripts)

After this, /usr/bin/nix-finish-install can be deleted, if desired.

The downside to the binary tarball is that it's pretty big (~55 MiB
for x86_64-linux).

Eelco Dolstra 591aab7e21 Remove $FONTCONFIG_FILE hack from nix-profile.sh
It's no longer needed because Nixpkgs' fontconfig uses
/etc/fonts/fonts.conf as a default, just like other distributions.

Eelco Dolstra 147f10157f Now *really* prevent accumulation of old manifests 2012-05-07 17:23:26 -04:00
Eelco Dolstra e060c99447 Use mkpath instead of make_path
Perl <= 5.10 doesn't have make_path.  See
e.g. http://hydra.nixos.org/build/2493981.

Eelco Dolstra 59a26360c7 Support mandatory system features in the build hook
Mandatory features are features that MUST be present in a derivation's
requiredSystemFeatures attribute.  One application is performance
testing, where we have a dedicated machine to run performance tests
(and nothing else).  Then we would add the label "perf" to the
machine's mandatory features and to the performance testing
derivations.

Eelco Dolstra 0b5107c016 If the (redirected) channel URL contains a version number, use it 2012-04-14 21:05:28 +02:00
Eelco Dolstra 1d0bafb74d Follow redirects early to ensure consistency between the manifest and the tarball
Without this change, if the URL is a redirect that changes in between,
we can get a manifest that doesn't match the tarball.

Eelco Dolstra ef902274fd Remove unnecessary "system" argument 2012-04-14 18:48:11 +02:00
Eelco Dolstra e855c7e2c9 nix-channel improvements
"nix-channel --add" now accepts a second argument: the channel name.
This allows channels to have a nicer name than (say) nixpkgs_unstable.
If no name is given, it defaults to the last component of the URL
(with "-unstable" or "-stable" removed).

Also, channels are now stored in a profile
(/nix/var/nix/profiles/per-user/$USER/channels).  One advantage of
this is that it allows rollbacks (e.g. if "nix-channel --update" gives
an undesirable update).

Eelco Dolstra 0837348049 Follow redirects when checking for the existence of MANIFEST.bz2
If we don't follow redirects, we might think that MANIFEST.bz2 exists
just because the HEAD request succeeds on the redirector URI.

Eelco Dolstra b8fb0ce563 Update "nix-build --help" 2012-03-27 11:59:36 +02:00
Eelco Dolstra 5144abe5b6 Add an option "--exclude" to filter dependencies in "nix-build --run-env"
Sometimes when doing "nix-build --run-env" you don't want all
dependencies to be built.  For instance, if we want to do "--run-env"
on the "build" attribute in Hydra's release.nix (to get Hydra's build
environment), we don't want its "tarball" dependency to be built.  So
we can do:

  $ nix-build --run-env release.nix -A build --exclude 'hydra-tarball'

This will skip the dependency whose name matches the "hydra-tarball"
regular expression.  The "--exclude" option can be repeated any number
of times.

Eelco Dolstra 3e94ffffd6 Allow the command executed by "nix-build --run-env" to be overriden with --command 2012-03-27 11:16:43 +02:00
Eelco Dolstra 7f38087f35 Add a command "nix-build --run-env" to reproduce the environment of a derivation
This command builds or fetches all dependencies of the given
derivation, then starts a shell with the environment variables from
the derivation.  This shell also sources $stdenv/setup to initialise
the environment further.

The current directory is not changed.  Thus this is a convenient way
to reproduce a build environment in an existing working tree.

Existing environment variables are left untouched (unless the
derivation overrides them).  As a special hack, the original value of
$PATH is appended to the $PATH produced by $stdenv/setup.

Example session:

$ nix-build --run-env '<nixpkgs>' -A xterm
(the dependencies of xterm are built/fetched...)
$ tar xf $src
$ ./configure
$ make
$ emacs
(... hack source ...)
$ make
$ ./xterm

Eelco Dolstra d645633643 nix-copy-closure: don't print copied path on stdout
We're already printing progress on stderr, so printing them on stdout
afterwards is kind of useless.

Eelco Dolstra 2b4964f319 Restore progress indication during nix-copy-closure 2012-03-05 18:13:44 +01:00
Eelco Dolstra 56042a120a build-remote.pl: don't wait forever for the upload lock
In the build hook, don't wait forever to get the upload lock.  This
ensures progress if another process gets stuck while holding the
upload lock.

Eelco Dolstra ce86a9a0ae * nix-channel: fail if we don't have write permission to the manifests
directory.  Previously in this situation we did add the Nix
  expressions from the channel to allow installation from source, but
  this doesn't work for binary-only channels and leads to confusing
  error messages.
2012-02-02 12:25:56 +00:00
Eelco Dolstra 2a3f4110c5 * nix-build: put the temporary derivation symlink in a temporary
directory rather than the current directory.
* nix-build: --drv-link now implies --add-drv-link.
2012-01-13 23:35:07 +00:00
Eelco Dolstra d4e6b9f2d6 * Doh! 2012-01-05 21:07:12 +00:00
Eelco Dolstra a7366a764a * Add a -I flag to the Perl bindings to nix-build and some other
scripts.
* Include the version and architecture in the -I flag so that there is
  at least a chance that a Nix binary built for one Perl version will
  run on another version.
2012-01-05 20:33:46 +00:00
Eelco Dolstra 39d45a6b09 * Add a test for nix-channel.
* Refactor the nix-channel unpacker a bit.
2012-01-03 01:51:38 +00:00
Eelco Dolstra dadbb51d96 * Use Nix::Config. 2012-01-03 00:47:27 +00:00
Eelco Dolstra 48cea0d01e * Refactoring: Get rid of a few subdirectories in corepkgs/, and some
other simplifications.
* Use <nix/...> to locate the corepkgs.  This allows them to be
  overriden through $NIX_PATH.
* Use bash's pipefail option in the NAR builder so that we don't need
  to create a temporary file.
2012-01-03 00:16:29 +00:00
Eelco Dolstra 4d728bc3e6 * Security: make sure the lock files used by build-remote.pl are not
readable to other users.  Otherwise, any user can open the lock file
  for reading and lock it, thus DoSing the remote build mechanism.
2011-12-21 19:11:58 +00:00
Eelco Dolstra 69d6f0936a * Use a lock to ensure that only one build-remote instance can copy a
closure to a given machine at the same time.  This prevents the case
  where multiple instances try to copy the same missing store path to
  the target machine, which is very wasteful.
2011-12-21 18:59:25 +00:00
Eelco Dolstra a67b8ae224 * Typo. 2011-12-15 14:04:35 +00:00
Eelco Dolstra 3964d95abf * nix-prefetch-url: rewritten in Perl. 2011-12-02 12:09:50 +00:00
Eelco Dolstra 1749a7b0ae * download-using-manifests: use the Perl bindings. 2011-11-29 13:01:24 +00:00
Eelco Dolstra 216440b3ff * For consistency with "nix-store -q --hash", produce hashes in
base-32.  (This affects Hydra manifests.)
2011-11-29 12:32:55 +00:00
Eelco Dolstra 1df120cb05 * Get rid of the shell in ssh calls. 2011-11-29 10:51:22 +00:00
Eelco Dolstra d5ac78e0d6 * Add bzip2 and xz support to nix-copy-closure. 2011-11-23 15:29:58 +00:00
Eelco Dolstra 5bbd693cae * Add an API function exportPaths() that provides the functionality of
‘nix-store --export’.
* Add a Perl module that provides the functionality of
  ‘nix-copy-closure --to’.  This is used by build-remote.pl so it no
  longer needs to start a separate nix-copy-closure process.  Also, it
  uses the Perl API to do the export, so it doesn't need to start a
  separate nix-store process either.  As a result, nix-copy-closure
  and build-remote.pl should no longer fail on very large closures due
  to an "Argument list too long" error.  (Note that having very many
  dependencies in a single derivation can still fail because the
  environment can become too large.  Can't be helped though.)

Eelco Dolstra ab20af3e6f * build-remote.pl: drop a hard-coded reference to /nix/etc/nix. 2011-11-23 12:21:35 +00:00
Eelco Dolstra f8e609c341 * nix-pull: update the Nix manifest cache if necessary. Also, don't
read the manifest just to check the version and print the number of
  paths.  This makes nix-pull very fast for the cached cache (speeding
  up nixos-rebuild without the ‘--no-pull’ or ‘--fast’ options).
2011-11-16 16:41:48 +00:00
Eelco Dolstra d7d7910ba4 * Don't decompress the manifests in /nix/var/nix/manifest. This saves
disk space, and, since they're typically only decompressed once (to
  fill the manifest cache), doesn't make things slower.
2011-11-16 16:25:38 +00:00
Eelco Dolstra 00b41e46ed * Print a consistent message. 2011-10-19 21:34:13 +00:00
Eelco Dolstra f186a9141e * nix-copy-closure: support ‘--dry-run’ and ‘--include-outputs’. 2011-10-18 21:21:22 +00:00
Eelco Dolstra 6761757428 * Use the Store API bindings in nix-copy-closure. 2011-10-11 15:41:13 +00:00
