2016-11-10 Store::computeFSClosure(): Support a set of pathsEelco Dolstra1-7/+5
This way, callers can exploits the parallelism of computeFSClosure() when they have multiple paths that they need the (combined) closure of.
2016-09-21 printMsg(lvlError, ...) -> printError(...) etc.Eelco Dolstra1-3/+3
2016-08-10 Add a "root" parameter to local storesEelco Dolstra1-2/+6
This makes it easier to create a diverted store, i.e. NIX_REMOTE="local?root=/tmp/root" instead of NIX_REMOTE="local?real=/tmp/root/nix/store&state=/tmp/root/nix/var/nix" NIX_LOG_DIR=/tmp/root/nix/var/log
2016-07-26 makeFixedOutputPath(): Drop superfluous HashType argumentEelco Dolstra1-2/+1
2016-06-02 Allow setting the state directory as a store parameterEelco Dolstra1-14/+20
E.g. "local?store=/tmp/store&state=/tmp/var".
2016-06-01 Make the store directory a member variable of StoreEelco Dolstra1-25/+25
2016-05-31 nix-copy-closure / build-remote.pl: Disable signature checkingEelco Dolstra1-1/+1
This restores the Nix 1.11 behaviour.
2016-05-04 Cleanup: Remove singleton()Eelco Dolstra1-4/+4
2016-05-04 Do compression in a sinkEelco Dolstra1-2/+0
2016-05-04 Add a Store::addToStore() variant that accepts a NAREelco Dolstra1-4/+2
As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
2016-05-04 Remove OpenSSL-based signingEelco Dolstra1-11/+7
2016-04-29 nix-store -l: Simplify implementationEelco Dolstra1-15/+2
2016-04-19 Move path info caching from BinaryCacheStore to StoreEelco Dolstra3-39/+31
Caching path info is generally useful. For instance, it speeds up "nix path-info -rS /run/current-system" (i.e. showing the closure sizes of all paths in the closure of the current system) from 5.6s to 0.15s. This also eliminates some APIs like Store::queryDeriver() and Store::queryReferences().
2016-04-08 Remove failed build cachingEelco Dolstra1-22/+0
This feature was implemented for Hydra, but Hydra no longer uses it.
2016-03-22 Don't overload dumpPath()Eelco Dolstra1-1/+1
2016-03-21 Add Store::dumpPath() methodEelco Dolstra1-1/+3
This allows applying nix-store --verify-path to binary cache stores: NIX_REMOTE=https://cache.nixos.org nix-store --verify-path /nix/store/s5c7...
2016-02-26 importPaths(): Optionally add NARs to binary cache accessorEelco Dolstra1-2/+2
This enables an optimisation in hydra-queue-runner, preventing a download of a NAR it just uploaded to the cache when reading files like hydra-build-products.
2016-02-24 Eliminate reserveSpace flagEelco Dolstra1-1/+1
2016-02-16 Rename ValidPathInfo::hash -> narHash for consistencyEelco Dolstra1-6/+6
2016-02-11 Move addPermRoot into StoreEelco Dolstra1-2/+2
2016-02-04 More of the sameEelco Dolstra5-13/+13
2016-02-04 StoreAPI -> StoreEelco Dolstra5-10/+10
Calling a class an API is a bit redundant...
2016-02-04 Eliminate the "store" global variableEelco Dolstra5-34/+39
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2016-01-31 Add build mode to compute fixed-output derivation hashesEelco Dolstra1-0/+1
For example, $ nix-build --hash -A nix-repl.src will build the fixed-output derivation nix-repl.src (a fetchFromGitHub call), but instead of *verifying* the hash given in the Nix expression, it prints out the resulting hash, and then moves the result to its content-addressed location in the Nix store. E.g build produced path ‘/nix/store/504a4k6zi69dq0yjc0bm12pa65bccxam-nix-repl-8a2f5f0607540ffe56b56d52db544373e1efb980-src’ with sha256 hash ‘0cjablz01i0g9smnavhf86imwx1f9mnh5flax75i615ml71gsr88’ The goal of this is to make all nix-prefetch-* scripts unnecessary: we can just let Nix run the real thing (i.e., the corresponding fetch* derivation). Another example: $ nix-build --hash -E 'with import <nixpkgs> {}; fetchgit { url = "https://github.com/NixOS/nix.git"; sha256 = "ffffffffffffffffffffffffffffffffffffffffffffffffffff"; }' ... git revision is 9e7c1a4bbdbe6129dd9dc385776612c307d3d1bb ... build produced path ‘/nix/store/gmsnh9i7x4mb7pyd2ns7n3c9l90jfsi1-nix’ with sha256 hash ‘1188xb621diw89n25rifqg9lxnzpz7nj5bfh4i1y3dnis0dmc0zp’ (Having to specify a fake sha256 hash is a bit annoying...)

2015-07-17 Allow remote builds without sending the derivation closureEelco Dolstra2-10/+33
Previously, to build a derivation remotely, we had to copy the entire closure of the .drv file to the remote machine, even though we only need the top-level derivation. This is very wasteful: the closure can contain thousands of store paths, and in some Hydra use cases, include source paths that are very large (e.g. Git/Mercurial checkouts). So now there is a new operation, StoreAPI::buildDerivation(), that performs a build from an in-memory representation of a derivation (BasicDerivation) rather than from a on-disk .drv file. The only files that need to be in the Nix store are the sources of the derivation (drv.inputSrcs), and the needed output paths of the dependencies (as described by drv.inputDrvs). "nix-store --serve" exposes this interface. Note that this is a privileged operation, because you can construct a derivation that builds any store path whatsoever. Fixing this will require changing the hashing scheme (i.e., the output paths should be computed from the other fields in BasicDerivation, allowing them to be verified without access to other derivations). However, this would be quite nice because it would allow .drv-free building (e.g. "nix-env -i" wouldn't have to write any .drv files to disk). Fixes #173.

This ensures proper permissions for the secret key.

2015-02-04 Use libsodium instead of OpenSSL for binary cache signingEelco Dolstra2-3/+33
Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA signatures. Public keys are also much shorter, so they're now specified directly in the nix.conf option ‘binary-cache-public-keys’. The new command ‘nix-store --generate-binary-cache-key’ generates and prints a public and secret key.
