Eelco Dolstra 967d066d8e nix-store --gc: Make ‘--max-freed 0’ do the right thing
That is, delete almost nothing (it will still remove unused links from
/nix/store/.links).

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 ca94b38371 nix-env: Ignore manifest.nix when recursing into ~/.nix-defexpr
Channels are implemented using a profile now, and profiles contain a
manifest.nix file.  This should be ignored to prevent bogus packages
from showing up in nix-env.

Eelco Dolstra 4d1b64f118 Allow daemon users to override ‘binary-caches’
For security reasons, daemon users can only specify caches that appear
in the ‘binary-caches’ and ‘trusted-binary-caches’ options in
nix.conf.

Eelco Dolstra ab42bf1dab nix-install-package: Support binary caches
The .nixpkg file format is extended to optionally include the URL of a
binary cache, which will be used in preference to the manifest URL
(which can be set to a non-existent value).

Eelco Dolstra d059bf48e4 Pass configuration settings to the substituters
Previously substituters could read nix.conf themselves, but this

Eelco Dolstra 66a3ac6a56 Allow a binary cache to declare that it doesn't support "nix-env -qas"
Querying all substitutable paths via "nix-env -qas" is potentially
hard on a server, since it involves sending thousands of HEAD
requests.  So a binary cache must now have a meta-info file named
"nix-cache-info" that specifies whether the server wants this.  It
also specifies the store prefix so that we don't send useless queries
to a binary cache for a different store prefix.

Eelco Dolstra 73acb8b836 Let build.cc verify the expected hash of a substituter's output
Since SubstitutionGoal::finished() in build.cc computes the hash
anyway, we can prevent the inefficiency of computing the hash twice by
letting the substituter tell Nix about the expected hash, which can
then verify it.

Eelco Dolstra 3a8f841612 download-using-manifests: Don't use nix-prefetch-url
Instead call curl directly and pipe it into ‘nix-store --restore’.
This saves I/O and prevents creating garbage in the Nix store.

Shea Levy f5954e2d94 prim_import: When importing .drvs, allocate the intermediate attrset on the heap just in case it escapes the stack frame. 2012-07-25 09:30:17 -04:00
Shea Levy 1ef2d5765b Turn tests back on 2012-07-25 09:30:17 -04:00
Shea Levy b1112bbef1 import: If the path is a valid .drv file, parse it and generate a derivation attrset.
The generated attrset has drvPath and outPath with the right string context, type 'derivation', outputName with
the right name, all with a list of outputs, and an attribute for each output.

I see three uses for this (though certainly there may be more):

* Using derivations generated by something besides nix-instantiate (e.g. guix)

* Allowing packages provided by channels to be used in nix expressions. If a channel installed a valid deriver
  for each package it provides into the store, then those could be imported and used as dependencies or installed
  in environment.systemPackages, for example.

* Enable hydra to be consistent in how it treats inputs that are outputs of another build. Right now, if an
  input is passed as an argument to the job, it is passed as a derivation, but if it is accessed via NIX_PATH
  (i.e. through the <> syntax), then it is a path that can be imported. This is problematic because the build
  being depended upon may have been built with non-obvious arguments passed to its jobset file. With this
  feature, hydra can just set the name of that input to the path to its drv file in NIX_PATH
