Eelco Dolstra 4695f4edd6 * nix-pull: support bzipped manifests: when doing a nix-pull on $url,
try $url.bz2 first.
2007-08-10 01:42:00 +00:00
Eelco Dolstra 911bc01454 * Enable nix-prefetch-url caching in nix-channel. 2007-08-10 00:28:44 +00:00
Eelco Dolstra 5e52df18fe * Don't rely on /dev/stdin. 2007-08-10 00:22:21 +00:00
Eelco Dolstra c5e934dcc9 * nix-pull: using nix-prefetch-url (so that we get caching for free),
and store the manifests in the Nix store.  (So now
  /nix/var/nix/manifests/ just contains symlinks to the store and is
  searched for GC roots.)
2007-08-09 23:52:53 +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 ef240bc0d5 * Use the new patched version of the aterm library. 2007-08-07 23:40:39 +00:00
Eelco Dolstra d71cc503a6 * Don't allocate input files on the stack. 2007-08-07 15:00:13 +00:00
Eelco Dolstra 4cad125e08 * Optionally warn about packages that give an assertion failure. 2007-08-06 16:08:09 +00:00
Eelco Dolstra 6da6fbfbe9 * Properly keep packages during upgrades. 2007-07-05 20:33:04 +00:00
Eelco Dolstra 6d1a1191b0 * Support queryDeriver() in multi-user installations. 2007-06-12 16:53:44 +00:00
Eelco Dolstra 9d9e1c5c41 * Distribute bzip2 1.0.4. 2007-06-11 13:59:07 +00:00
Eelco Dolstra 9bff7ad728 * Check against creation of GC roots in the store. Those roots don't
work, because findRoots() stops when it encounters a symlink to the
  store.  And of course the store is supposed to be read-only.
2007-06-11 11:36:22 +00:00
Eelco Dolstra f3ebd03bb1 * Remove debug statement. 2007-06-04 12:03:33 +00:00
Armijn Hemel 40b6f06f09 change default NIX_HASH_ALGO 2007-06-02 15:03:54 +00:00
Eelco Dolstra b47da5ea21 2007-05-16 22:07:39 +00:00
Eelco Dolstra bddc83a148 * New builtin function "isFunction". You're not supposed to use it
;-)
* Channels: fix channels that are plain lists of derivations (like
  strategoxt-unstable) instead  of functions (like nixpkgs-unstable).
  This fixes the error message "error: the left-hand side of the
  function call is neither a function nor a primop (built-in
  operation) but a list".
2007-05-16 16:17:04 +00:00
Eelco Dolstra ca00aa1171 * Allow empty argument lists in function definitions (e.g., `{}:
bla').  Also allow trailing commas (`{x, y,}: ...') as a unintented
  consequence.  Hopefully the reduce/reduce conflict won't cause any
  problems.
2007-05-15 12:14:37 +00:00
Eelco Dolstra 7046c35843 * Typo (reported by Marc Weber). 2007-05-14 12:16:41 +00:00
Eelco Dolstra e5da9c8803 * Create the database directory if it doesn't exist. 2007-05-07 16:59:19 +00:00
Eelco Dolstra 30beeb27a9 * Set the right priorities when recovering from a directory
collision.
2007-05-02 19:38:02 +00:00
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 a9d15d4f43 * nix-env -i: instead of breaking package ties by version, break them
by priority and version install.  That is, if there are multiple
  packages with the same name, then pick the package with the highest
  priority, and only use the version if there are multiple packages
  with the same priority.

  This makes it possible to mark specific versions/variant in Nixpkgs
  more or less desirable than others.  A typical example would be a
  beta version of some package (e.g., "gcc-4.2.0rc1") which should not
  be installed even though it is the highest version, except when it
  is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1").

* Idem for nix-env -u, only the semantics are a bit trickier since we
  also need to take into account the priority of the currently
  installed package (we never upgrade to a lower priority, unless
  --always is given).

Eelco Dolstra cbfac2fdcc * Set a terminate() handler to ensure that we leave the BDB
environment cleanly even when an exception is thrown from a
  destructor.  We still crash, but we don't take all other Nix
  processes with us.
2007-05-01 15:16:17 +00:00
Eelco Dolstra 644946feed * Make --verify more interruptable. 2007-05-01 13:21:05 +00:00
Eelco Dolstra bd1f66453a * `nix-env -q --xml --meta' to show all meta attributes. 2007-05-01 11:30:52 +00:00
Eelco Dolstra e20f0da22c * Doh. 2007-04-30 18:41:27 +00:00
Eelco Dolstra 89c1d2b202 * Package flag "keep" that prevents a package from being removed from
a user environment by an install or upgrade action.  This is
  particularly useful if you have a version installed that you don't
  want to upgrade (e.g., because the newer versions are broken).
  Example:

    $ nix-env -u zapping --dry-run
    (dry run; not doing anything)
    upgrading `zapping-0.9.6' to `zapping-0.10cvs6'

    $ nix-env --set-flag keep true zapping

    $ nix-env -u zapping --dry-run
    (dry run; not doing anything)

  However, "-e" will still uninstall the package.  (Maybe we should
  require the keep flag to be explicitly set to false before it can be
  uninstalled.)
2007-04-27 23:48:14 +00:00
Eelco Dolstra a46db5d013 * Package conflict resolution through priority levels. If there is a
user environment collission between two packages due to overlapping
  file names, then a package with a higher priority will overwrite the
  symlinks of a package with a lower priority.  E.g.,

    $ nix-env --set-flag priority 5 gcc
    $ nix-env --set-flag priority 10 binutils

  gives gcc a higher priority than binutils (higher number = lower
  priority).
2007-04-27 23:28:44 +00:00
Eelco Dolstra 3d05166086 * Allow conflicting packages to be kept in a user environment, and
allow switching between them (NIX-80).

  Example: two versions of Pan:

    $ nix-env -q pan
    pan-0.128
    pan-0.14.2.91

    $ readlink $(which pan)
    /nix/store/l38jrbilw269drpjkx7kinhrxj6fjh59-pan-0.14.2.91/bin/pan

  At most one of them can be active any given time.  Assuming than
  0.14.2.91 is active, you can active 0.128 as follows:

    $ nix-env --set-flag active false pan-0.14.2.91
    $ nix-env --set-flag active true pan-0.128

    $ readlink $(which pan)
    /nix/store/nziqwnlzy7xl385kglxhg75pfl5i936n-pan-0.128/bin/pan

  More flags to follow.
2007-04-27 22:40:59 +00:00
Eelco Dolstra b7f0f65c19 * nix-env -q now has a flag --prebuilt-only (-b<) that causes nix-env
to show only those derivations whose output is already in the Nix
  store or that can be substituted (i.e., downloaded from somewhere).
  In other words, it shows the packages that can be installed “quickly”,
  i.e., don’t need to be built from source.
2007-04-26 14:20:31 +00:00
Eelco Dolstra 5dc05b76ab * Updated dependency information. 2007-04-16 16:08:44 +00:00
Eelco Dolstra 5f2492eaec * New primop "throw <string>" to throw an error. This is like abort,
only thrown errors are caught by the top-level derivation evaluation
  in nix-env -qa / -i.
2007-04-16 15:03:19 +00:00
Eelco Dolstra 0a8eeea9d8 * Remove a warning. 2007-04-16 14:45:25 +00:00
Eelco Dolstra 2716f9bc5f * It seems that svnversion prints a carriage return on Cygwin, so we
get a invalid #define VERSION.  Use "svnversion -n" to leave out the
  newline.  Fix provided by Marc Weber.
2007-04-16 12:00:13 +00:00
Eelco Dolstra ae7990cc88 * Work around a bug in Apple's GCC preprocessor. 2007-03-30 13:24:35 +00:00
Eelco Dolstra 4caca58ff7 * Make the maximum patch size configurable. 2007-03-30 09:01:05 +00:00
Eelco Dolstra 17b506c0c7 * Handle ECONNRESET from the client. Also, don't abort() if there are
unexpected conditions in the SIGPOLL handler, since that messes up
  the Berkeley DB environment (which a client must never be able to
  trigger).
2007-03-28 15:46:21 +00:00
Eelco Dolstra efd31139df * Forgot a @bindir@. 2007-03-27 09:53:58 +00:00
Eelco Dolstra d303b389a9 * `nix-copy-closure --from': copy from a remote machine instead of to
a remote machine.
2007-03-26 21:05:17 +00:00
Eelco Dolstra 7edd2e2cd2 * Refactoring. 2007-03-26 20:49:22 +00:00
Eelco Dolstra f3584ff535 * Fix URL/description. 2007-03-21 12:39:55 +00:00
Eelco Dolstra 803cb6e3b9 * Override the setuid helper using NIX_SETUID_HELPER. 2007-03-20 22:04:25 +00:00
Eelco Dolstra a8ea4cbcc8 * Scan /proc/sys/kernel/modprobe for roots to prevent the kernel
modules for the running kernel from being garbage-collected.  Idem
  for /proc/sys/kernel/fbsplash.
2007-03-20 11:13:15 +00:00
Eelco Dolstra 8ab229ddf2 * Terminate build hooks and substitutes with a TERM signal, not a KILL
signal.  This is necessary because those processes may have joined
  the BDB environment, so they have to be given a chance to clean up.
  (NIX-85)
2007-03-19 12:48:45 +00:00
Eelco Dolstra b2b6cf3fc8 * Undocumented option `gc-check-reachability' to allow reachability
checking to be turned off on machines with way too many roots.
2007-03-19 09:16:47 +00:00
Eelco Dolstra eb2dd4815c * Remove old generations in all directories under
/nix/var/nix/profiles, not just in that directory itself.  (NixOS
  puts profiles in /nix/var/nix/profiles/per-user.)
2007-03-13 11:30:57 +00:00
Eelco Dolstra 917e06bf63 * Delete the output paths before invoking the build hook. 2007-03-07 15:53:11 +00:00
Eelco Dolstra df0283ae86 * Get rid of those stupid --login tricks, it's the responsibility of
the remote system to make sure that Nix is in the $PATH.
2007-03-01 13:55:47 +00:00
Eelco Dolstra 30394a4f3f * sh -> bash. 2007-03-01 13:49:20 +00:00
