Eelco Dolstra bf4a577a58 Fix broken patch 2014-02-26 13:48:23 +01:00
Ian-Woo Kim 8a02fdc38e use USER environmental variable if getting user id by getpwuid is failed in perl scripts: download-from-binary-cache.pl and nix-channel 2014-02-26 13:42:11 +01:00
Eelco Dolstra 566afa1e9c Support xz compression of nixexprs.tar in channels 2012-12-05 11:02:44 +01:00
Eelco Dolstra a562d544d8 When ‘--help’ is given, just run ‘man’ to show the manual page
I.e. do what git does.  I'm too lazy to keep the builtin help text up
to date :-)

Also add ‘--help’ to various commands that lacked it
(e.g. nix-collect-garbage).

Eelco Dolstra b14717ab90 Delete manifests in "nix-channel --remove" or when a binary cache is available 2012-09-13 11:35:46 -04:00
Eelco Dolstra 5170c5691a nix-channel: Use binary caches advertised by channels
Channels can now advertise a binary cache by creating a file
<channel-url>/binary-cache-url.  The channel unpacker puts these in
its "binary-caches" subdirectory.  Thus, the URLS of the binary caches
for the channels added by root appear in
/nix/var/nix/profiles/per-user/eelco/channels/binary-caches/*.  The
binary cache substituter reads these and adds them to the list of
binary caches.

Eelco Dolstra e060c99447 Use mkpath instead of make_path
Perl <= 5.10 doesn't have make_path.  See

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 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 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 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 5090c34ee1 * Set the executable bit on scripts. 2011-10-10 22:40:17 +00:00
Eelco Dolstra 7ca9972636 * When doing a nix-pull, remove old manifests downloaded from the same
URL.  This prevents lots of old cruft accumulating in
  /nix/var/nix/manifests.
2009-12-09 19:36:54 +00:00
Eelco Dolstra 3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.

Eelco Dolstra 8ab6bc5a49 * nix-channel: use nix-build. 2009-02-27 11:01:03 +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".)

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 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).

Eelco Dolstra 911bc01454 * Enable nix-prefetch-url caching in nix-channel. 2007-08-10 00:28:44 +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.

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 d941186289 * Show more progress. 2006-11-18 19:03:45 +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

2004-12-20 16:38:50 +00:00
Eelco Dolstra 7eed57e784 * Sync with changed substitute mechanism.
* Accept the NarHash line.

Eelco Dolstra feb3ceaee0 * Better error messages. 2004-11-04 20:20:39 +00:00
Eelco Dolstra 2155c0a673 * Register channels as roots of the garbage collector (in
$(localstatedir)/nix/gcroots/channels). 
* In setuid installations, create gcroots/tmp and gcroots/channels
  group-writable.

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.
