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).

the BDB environment, so they have to be given a chance to clean up.

from a source directory. All files for which a predicate function
returns true are copied to the store. Typical example is to leave
out the .svn directory:
stdenv.mkDerivation {
...
src = builtins.filterSource
(path: baseNameOf (toString path) != ".svn")
./source-dir;
# as opposed to
# src = ./source-dir;
}
This is important because the .svn directory influences the hash in
a rather unpredictable and variable way.

very carefully, since it can invalidate iterators into the

* Throw more exceptions as BuildErrors instead of Errors. This
matters when --keep-going is turned on. (A BuildError is caught
and terminates the goal in question, an Error terminates the
program.)

seconds without producing output on stdout or stderr (NIX-65). This
timeout can be specified using the `--max-silent-time' option or the
`build-max-silent-time' configuration setting. The default is
infinity (0).
* Fix a tricky race condition: if we kill the build user before the
child has done its setuid() to the build user uid, then it won't be
killed, and we'll potentially lock up in pid.wait(). So also send a
conventional kill to the child.

containing functions that operate on the Nix store. One
implementation is LocalStore, which operates on the Nix store
directly. The next step, to enable secure multi-user Nix, is to
create a different implementation RemoteStore that talks to a
privileged daemon process that uses LocalStore to perform the actual
operations.

graph to be passed to a builder. This attribute should be a list of
pairs [name1 path1 name2 path2 ...]. The references graph of each
`pathN' will be stored in a text file `nameN' in the temporary build
directory. The text files have the format used by `nix-store
--register-validity'. However, the deriver fields are left empty.
`exportReferencesGraph' is useful for builders that want to do
something with the closure of a store path. Examples: the builders
that make initrds and ISO images for NixOS.
`exportReferencesGraph' is entirely pure. It's necessary because
otherwise the only way for a builder to get this information would
be to call `nix-store' directly, which is not allowed (though
unfortunately possible).

check that the references of the output of a derivation are in the
specified set. For instance,
allowedReferences = [];
specifies that the output cannot have any references. (This is
useful, for instance, for the generation of bootstrap binaries for
stdenv-linux, which must not have any references for purity). It
could also be used to guard against undesired runtime dependencies,
e.g.,
{gcc, dynlib}: derivation {
...
allowedReferences = [dynlib];
}
says that the output can refer to the path of `dynlib' but not
`gcc'. A `forbiddedReferences' attribute would be more useful for
this, though.

writable. File permissions on Cygwin are rather complex, and in this
case this check introduced a problem with build jobs invoke from
outside of Cygwin (MSYS). It seemed almost impossible to fix the
permissions of the directory, so for now this safety check is disabled
on Cygwin.
