e0afaf1857 * Wow, that bug has been there since r764. 2006-09-14 22:48:59 +00:00

86cbd93ec1 * nix-env --switch-generation / --list-generations /
--delete-generations: lock the profile to prevent (extremely
  unlikely) race conditions.

5c38c863bd * Fix a huge gaping hole in nix-env w.r.t. the garbage collector.
Nix-env failed to call addPermRoot(), which is necessary to safely
  add a new root.  So if nix-env started after and finished before the
  garbage collector, the user environment (plus all other new stuff)
  it built might be garbage collected, leading to a dangling symlink
  chain in ~/.nix-profile...

* Be more explicit if we block on the GC lock ("waiting for the big
  garbage collector lock...").

* Don't loop trying to create a new generation.  It's not necessary
  anymore since profiles are locked nowadays.

f41297fdce * Allow --arg in nix-env as well, example:
$ nix-env -qa --system-filter \* --arg system '"powerpc-darwin"'

  to override the system from the default value (__currentSystem in
  all-packages.nix).

0e6dc72a7a * Applied rbroek's patch from the branch at
https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/,
  with some modifications.  This allows `nix-env -qa' to show the
  attribute path that can be used to unambiguously install a package
  using `nix-env -i -A'.  Example:

    $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server
    subversionWithJava  subversion-1.2.3
    subversion          subversion-1.3.2
    subversion14        subversion-1.4.0pre-rc1
    xorg.xorgserver     xorg-server-1.1.0
2006-07-25 16:40:38 +00:00
Eelco Dolstra
5744dd5480 * Support the --attr / -A flag in nix-env as well. So now we can do,
e.g.,

  $ nix-env -i -A subversion xorg.xorgserver

  The main advantage over using symbolic names is that using attribute
  names is unambiguous and much, much faster.

to the new version.  This is actually useful.

9d72bf8835 * 64-bit compatibility fixes (for problems revealed by building on an Athlon
64 running 64-bit SUSE).  A patched ATerm library is required to run Nix

b52e711910 * Huge reduction in memory use (2/3 or so on large nix-env -qas
operations): share ATermMaps between DrvInfos.

37d1b1cafd * `nix-env -qa --description' shows human-readable descriptions of
packages (provided that they have a `meta.description' attribute).
  E.g.,

  $ ./src/nix-env/nix-env -qa --description gcc
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x

4ada6db1fc * `nix-env -q' now accepts arguments that allow specific derivations
to be queried, e.g., `nix-env -qa firefox'.  This does require the
  argument '*' to be passed if one wants information about all
  derivations, so the old `nix-env -qa' now is `nix-env -qa "*"'.

6dca5c9099 * When obtaining derivations from Nix expressions, ignore all
expressions that cause an assertion failure (like `assert system ==
  "i686-linux"').  This allows all-packages.nix in Nixpkgs to be used
  on all platforms, even if some Nix expressions don't work on all
  platforms.

  Not sure if this is a good idea; it's a bit hacky.  In particular,
  due to laziness some derivations might appear in `nix-env -qa' but
  disappear in `nix-env -qas' or `nix-env -i'.

46f0cb0869 * In "nix-env -i", print a warning if there are multiple derivations
with the same name *and* version number, and pick the first one
  (this means that the order in which channels appear in
  ~/.nix-channels matters).  E.g.:

    $ nix-env ii aterm
    warning: there are multiple derivations named `aterm-2.4.2'; using the first one
    installing `aterm-2.4.2'

7a3e715980 * Fix for NIX-31: "nix-env -i foo" installing all derivations named
foo.  Now it will only install the one with the highest version
  number.

b87b9c0d1f * New query option: --compare-versions' or -c' to compare installed
versions to available versions, or vice versa.

  For example, the following compares installed versions to available
  versions:

    $ nix-env -qc
    autoconf-2.59            = 2.59
    automake-1.9.4           < 1.9.6
    f-spot-0.0.10            - ?
    firefox-1.0.4            < 1.0.7
    ...

  I.e., there are newer versions available (in the current default Nix
  expression) for Automake and Firefox, but not for Autoconf, and
  F-Spot is missing altogether.

  Conversely, the available versions can be compared to the installed
  versions:

    $ nix-env -qac
    autoconf-2.59                  = 2.59
    automake-1.9.6                 > 1.9.4
    bash-3.0                       - ?
    firefox-1.0.7                  > 1.0.4
    ...

  Note that bash is available but no version of it is installed.

  If multiple versions are available for comparison, then the highest
  is used.  E.g., if Subversion 1.2.0 is installed, and Subversion
  1.1.4 and 1.2.3 are available, then `nix-env -qc' will print `<
  1.2.3', not `> 1.1.4'.

  If higher versions are available, the version column is printed in
  red (using ANSI escape codes).

edd145d2fb * Lazily compute the derivation and output paths of derivations. This
makes most query and installation operations much faster (e.g.,
  `nix-env -qa' on the current Nixpkgs is about 10 times faster).

e17910cfb5 * And yet another installation source: the ability to copy user
environment elements from one user environment to another, e.g.,

    $ nix-env -i --from-profile /nix/var/nix/profiles/other-profile aterm
    
  copies the `aterm' component installed in the `other-profile' to the
  user's current profile.
2005-02-15 10:49:31 +00:00
Eelco Dolstra
8992fce3da * It is now possible to add store derivations or paths directly to a
user environment, e.g.,

    $ nix-env -i /nix/store/z58v41v21xd3ywrqk1vmvdwlagjx7f10-aterm-2.3.1.drv

  or 

    $ nix-env -i /nix/store/hsyj5pbn0d9iz7q0aj0fga7cpaadvp1l-aterm-2.3.1

  This is useful because it allows Nix expressions to be bypassed
  entirely.  For instance, if only a nix-pull manifest is provided,
  plus the top-level path of some component, it can be installed
  without having to supply the Nix expression (e.g., for obfuscation,
  or to be independent of Nix expression language changes or context
  dependencies).

e446d342b7 * Added an installation source --from-expression' (or -E') to
install derivations from a Nix expression specified on the command
  line.  This is particularly useful for disambiguation if there are
  multiple derivations with the same name.  For instance, in Nixpkgs,
  to install the Firefox wrapper rather than the plain Firefox
  component:

    $ nix-env -f .../i686-linux.nix -i -E 'x: x.firefoxWrapper'

  The Nix expressions should be functions to which the default Nix
  expression (in this case, `i686-linux.nix') is passed, hence `x:
  ...'.

  This might also be a nice way to deal with high-level (user-level)
  variability, e.g.,

    $ nix-env -f ./server.nix -i -E 'x: x {port = 8080; ssl = false;}'

6a8ef36fe6 * Global configuration option `env-keep-derivations' to store pointer
to derivations in user environments.  Nice for developers (since it
  prevents build-time-only dependencies from being GC'ed, in
  conjunction with `gc-keep-outputs').  Turned off by default.
