‘nix-store --export’.
* Add a Perl module that provides the functionality of
‘nix-copy-closure --to’. This is used by build-remote.pl so it no
longer needs to start a separate nix-copy-closure process. Also, it
uses the Perl API to do the export, so it doesn't need to start a
separate nix-store process either. As a result, nix-copy-closure
and build-remote.pl should no longer fail on very large closures due
to an "Argument list too long" error. (Note that having very many
dependencies in a single derivation can still fail because the
environment can become too large. Can't be helped though.)
libstore so that the Perl bindings can use it as well. It's vital
that the Perl bindings use the configuration file, because otherwise
nix-copy-closure will fail with a ‘database locked’ message if the
value of ‘use-sqlite-wal’ is changed from the default.
read the manifest just to check the version and print the number of
paths. This makes nix-pull very fast for the cached cache (speeding
up nixos-rebuild without the ‘--no-pull’ or ‘--fast’ options).
bindings to be used in Nix's own Perl scripts.
The only downside is that Perl XS and Automake/libtool don't really
like each other, so building is a bit tricky.
