2014-07-11build-remote.pl: Use ‘nix-store --serve’ on the remote sideEelco Dolstra
This makes things more efficient (we don't need to use an SSH master connection, and we only start a single remote process) and gets rid of locking issues (the remote nix-store process will keep inputs and outputs locked as long as they're needed). It also makes it more or less secure to connect directly to the root account on the build machine, using a forced command (e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix daemon and is therefore more efficient. Also, don't call nix-store to import the output paths.
2013-03-08Fix annoying Perl 5.16 warningsEelco Dolstra
I.e. Subroutine Nix::Store::isValidPath redefined at /nix/store/clfzsf6gi7qh5i9c0vks1ifjam47rijn-perl-5.16.2/lib/perl5/5.16.2/XSLoader.pm line 92. and so on.
2012-07-17Add function queryPathFromHashPart()Eelco Dolstra
To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-05-10Support building with the Perl XS bindings disabledEelco Dolstra
Since the Perl bindings require shared libraries, this is required on platforms such as Cygwin where we do a static build.
2012-03-19Add a command "nix-build --run-env" to reproduce the environment of a derivationEelco Dolstra
This command builds or fetches all dependencies of the given derivation, then starts a shell with the environment variables from the derivation. This shell also sources $stdenv/setup to initialise the environment further. The current directory is not changed. Thus this is a convenient way to reproduce a build environment in an existing working tree. Existing environment variables are left untouched (unless the derivation overrides them). As a special hack, the original value of $PATH is appended to the $PATH produced by $stdenv/setup. Example session: $ nix-build --run-env '<nixpkgs>' -A xterm (the dependencies of xterm are built/fetched...) $ tar xf $src $ ./configure $ make $ emacs (... hack source ...) $ make $ ./xterm
2011-12-02* Add some more functions to the Perl bindings.Eelco Dolstra
2011-11-29* Don't require a specific Perl version.Eelco Dolstra
2011-11-29* download-using-manifests: use the Perl bindings.Eelco Dolstra
2011-11-23* Add an API function exportPaths() that provides the functionality ofEelco Dolstra
‘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.)
2011-10-11* Use the Store API bindings in nix-copy-closure.Eelco Dolstra
2011-10-10* Include the Nix Perl bindings in Nix itself. This will allow theEelco Dolstra
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.
