001b3f06ec * `nix-env --set': support --dry-run. 2008-08-04 14:58:50 +00:00
Eelco Dolstra
a1d310b6b5 * `nix-store --realise': print what paths will be built/downloaded,
just like nix-env.
* `nix-store --realise': --dry-run option.

5adbb0aabe * build.cc: only use a substituter if it returns info for a path. 2008-08-04 13:15:35 +00:00
Eelco Dolstra
5b1052663a * Always show what paths we're going to build/download (as in
--dry-run).  Maybe there should be an option to turn this on/off?

c4f98941ed * nix-env --dry-run: show the total size of the substituter
downloads.

03427e76f1 * querySubstitutablePathInfo: work properly when run via the daemon.
* --dry-run: print the paths that we don't know how to build/substitute.

3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.

fc691e1cbd * Print a better error message when a non-derivation attribute set is
coerced to a string.
2008-07-24 14:52:25 +00:00
Eelco Dolstra
989176c56e * Allow read-only access to the store (e.g., non-root users on NixOS
can do operations like "nix-store -qR <path>" even without the Nix
  daemon).

8bc591a6f0 * Use the copy-from-other-stores substituter by default. Of course,
it only does something if $NIX_OTHER_STORES (not really a good
  name...) is set.
* Do globbing on the elements of $NIX_OTHER_STORES.  E.g. you could
  set it to /mnts/*/nix or something.
* Install substituters in libexec/nix/substituters.

7cd88b1dec * Generalised the dependencyClosure primop to builtins.genericClosure,
which is hopefully more useful.
* New primops: length, mul, div.

d567baabbd * Export the nix-env derivation name parsing and version comparison
logic through the `parseDrvName' and `compareVersions' primops.
  This will allow expressions to easily check whether some dependency
  is a specific needed version or falls in some version range.  See
  tests/lang/eval-okay-versions.nix for examples.

5af84139a8 * --max-freed: support values >= 4 GB. 2008-06-18 15:20:33 +00:00
Eelco Dolstra
d3aa183beb * Garbage collector: option `--max-freed' to stop after at least N
bytes have been freed, `--max-links' to stop when the Nix store
  directory has fewer than N hard links (the latter being important
  for very large Nix stores on filesystems with a 32000 subdirectories
  limit).

a8f3b02092 * `nix-store --optimise': handle files with >= 32000 hard links.
(There can easily be more than 32000 occurrences of the empty file.)

a72709afd8 * Some refactoring: put the GC options / results in separate structs.
* The garbage collector now also prints the number of blocks freed.

f351834f77 * nix-worker: clean up the temporary root for the worker processes
in /nix/var/nix/temproots.

826b271d9a * Garbage collector: don't do a complete topological sort of the Nix
store under the reference relation, since that means that the
  garbage collector will need a long time to start deleting paths.
  Instead just delete the referrers of a path first.

72034ab35d * sockaddr_un doesn't allow path names of more than 108 characters.
This isn't usually a problem, except that it causes tests to fail
  when performed in a directory with a very long path name.  So chdir
  to the socket directory and use a relative path name.

329025253d * Use /tmp/nix-build-<drvpath>-<counter> instead of
/tmp/nix-<pid>-<counter> for temporary build directories.  This
  increases purity a bit: many packages store the temporary build path
  in their output, causing (generally unimportant) binary differences.

98968fbb63 * Disable the don't-run-as-root sanity check because it breaks RPM
builds (which are done as root...).

f789ea1d09 * A transaction is unnecessary since the path cannot be
garbage-collected (it's a temporary root).

0a84137c45 * checkVarDefs: don't check in closed terms, which don't have
undefined variables by definition.  This matters for the
  implementation of "with", which does a call to checkVarDefs to see
  if the body of the with has no undefined variables.  (It can't be
  checked at parse time because you don't know which variables are in
  the "with" attribute set.)  If we check closed terms, then we check
  not just the with body but also the substituted terms, which are
  typically very large.  This is the cause of the poor nix-env
  performance on Nixpkgs lately.  It didn't happen earlier because
  "with" wasn't used very often in the past.

  This fix improves nix-env performance roughly 60x on current Nixpkgs.
  nix-env -qa is down from 29.3s to 0.5s on my laptop, and nix-env -qa
  --out-path is down from 229s to 3.39s.  Not bad for a 1-line fix :-)

0ed89c569f * Fix the parsing of
''
      '${foo}'
    ''
    
  where the antiquote should work as expected, instead of giving the
  string "'${foo}'".

66c51dc215 * nix-store --dump-db / --load-db to dump/load the Nix DB.
* nix-store --register-validity: option to supply the content hash of
  each path.
* Removed compatibility with Nix <= 0.7 stores.

b42ef9c054 * Syntax to escape '', ${. 2007-12-06 10:20:58 +00:00
Eelco Dolstra
6d6c68c0d2 * Added a new kind of multi-line string literal delimited by two
single quotes.  Example (from NixOS):

    job = ''
      start on network-interfaces

      start script

        rm -f /var/run/opengl-driver
        ${if videoDriver == "nvidia"        
          then "ln -sf ${nvidiaDrivers} /var/run/opengl-driver"
          else if cfg.driSupport
          then "ln -sf ${mesa} /var/run/opengl-driver"
          else ""
        }

        rm -f /var/log/slim.log

      end script
    '';

  This style has two big advantages:

  - \, ' and " aren't special, only '' and ${.  So you get a lot less
    escaping in shell scripts / configuration files in Nixpkgs/NixOS.
    The delimiter '' is rare in scripts (and can usually be written as
    "").  ${ is also fairly rare.

    Other delimiters such as <<...>>, {{...}} and <|...|> were also
    considered but this one appears to have the fewest drawbacks
    (thanks Martin).

  - Indentation is intelligently stripped so that multi-line strings
    can follow the nesting structure of the containing Nix
    expression.  E.g. in the example above 6 spaces are stripped from
    the start of each line.  This prevents unnecessary indentation in
    generated files (which sometimes even breaks things).

  See tests/lang/eval-okay-ind-string.nix for some examples.

633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.
