2016-08-10	Mark content-addressed paths in the Nix database and in .narinfo	Eelco Dolstra	1	-18/+55
	This allows such paths to be imported without signatures.
2016-08-10	Add a "root" parameter to local stores	Eelco Dolstra	1	-0/+2
	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 argument	Eelco Dolstra	1	-1/+1

2016-06-03	Support sandbox builds by non-root users	Eelco Dolstra	1	-0/+5
	This allows an unprivileged user to perform builds on a diverted store (i.e. where the physical store location differs from the logical location). Example: $ NIX_LOG_DIR=/tmp/log NIX_REMOTE="local?real=/tmp/store&state=/tmp/var" nix-build -E \ 'with import <nixpkgs> {}; runCommand "foo" { buildInputs = [procps nettools]; } "id; ps; ifconfig; echo $out > $out"' will do a build in the Nix store physically in /tmp/store but logically in /nix/store (and thus using substituters for the latter).
2016-06-02	Make derivationFromPath work on diverted stores	Eelco Dolstra	1	-0/+2

2016-06-02	Allow setting the state directory as a store parameter	Eelco Dolstra	1	-6/+8
	E.g. "local?store=/tmp/store&state=/tmp/var".
2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra	1	-62/+71

2016-05-31	nix-copy-closure / build-remote.pl: Disable signature checking	Eelco Dolstra	1	-3/+3
	This restores the Nix 1.11 behaviour.
2016-05-30	Re-implement the WantMassQuery property of binary caches	Eelco Dolstra	1	-0/+2

2016-05-30	Fix repair during substitution	Eelco Dolstra	1	-1/+1

2016-05-04	Add a Store::addToStore() variant that accepts a NAR	Eelco Dolstra	1	-16/+18
	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 signing	Eelco Dolstra	1	-7/+4

2016-05-04	Add a copyStorePath() utility function	Eelco Dolstra	1	-0/+5

2016-04-29	BinaryCacheStore: Make the signing key a parameter	Eelco Dolstra	1	-4/+0

2016-04-29	Allow parameters in store URIs	Eelco Dolstra	1	-2/+5
	This is to allow store-specific configuration, e.g. s3://my-cache?compression=bzip2&secret-key=/path/to/key.
2016-04-29	Eliminate the substituter mechanism	Eelco Dolstra	1	-0/+6
	Substitution is now simply a Store -> Store copy operation, most typically from BinaryCacheStore to LocalStore.
2016-04-21	Implement S3BinaryCacheStore::queryAllValidPaths()	Eelco Dolstra	1	-3/+8
	This allows commands like "nix verify --all" or "nix path-info --all" to work on S3 caches. Unfortunately, this requires some ugly hackery: when querying the contents of the bucket, we don't want to have to read every .narinfo file. But the S3 bucket keys only include the hash part of each store path, not the name part. So as a special exception queryAllValidPaths() can now return store paths without the name part, and queryPathInfo() accepts such store paths (returning a ValidPathInfo object containing the full name).
2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra	1	-0/+7
	This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-04-19	Move path info caching from BinaryCacheStore to Store	Eelco Dolstra	1	-12/+50
	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().
2016-04-15	BinaryCacheStore::readFile(): Return a shared_ptr to a string	Eelco Dolstra	1	-0/+1
	This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-04-08	Remove failed build caching	Eelco Dolstra	1	-8/+0
	This feature was implemented for Hydra, but Hydra no longer uses it.
2016-04-07	nix verify-paths: Add ‘--sigs-needed <N>’ flag	Eelco Dolstra	1	-0/+3
	This specifies the number of distinct signatures required to consider each path "trusted". Also renamed ‘--no-sigs’ to ‘--no-trust’ for the flag that disables verifying whether a path is trusted (since a path can also be trusted if it has no signatures, but was built locally).
2016-04-05	Add "nix copy-sigs" command	Eelco Dolstra	1	-0/+4
	This imports signatures from one store into another. E.g. $ nix copy-sigs -r /run/current-system -s https://cache.nixos.org/ imported 595 signatures
2016-03-30	Improve the SQLite wrapper API	Eelco Dolstra	1	-2/+2
	In particular, this eliminates a bunch of boilerplate code.
2016-03-24	Move signature support from NarInfo to ValidPathInfo	Eelco Dolstra	1	-0/+15

2016-03-22	Don't overload dumpPath()	Eelco Dolstra	1	-2/+2

2016-03-21	Move signatures from NarInfo to ValidPathInfo	Eelco Dolstra	1	-0/+7
	This allows queryPathInfo() to return signatures.
2016-03-21	Add Store::dumpPath() method	Eelco Dolstra	1	-0/+5
	This allows applying nix-store --verify-path to binary cache stores: NIX_REMOTE=https://cache.nixos.org nix-store --verify-path /nix/store/s5c7...
2016-03-14	Fix another mismatched tag	Eelco Dolstra	1	-1/+1
	http://hydra.nixos.org/build/33279570
2016-03-04	BinaryCacheStore: Remove publicKeyFile argument	Eelco Dolstra	1	-2/+1
	The public key can be derived from the secret key, so there's no need for the user to supply it separately.
2016-03-02	Provide function required by Hydra	Eelco Dolstra	1	-0/+5

2016-03-02	Make store implementations pluggable	Eelco Dolstra	1	-0/+17
	This for instance allows hydra-queue-runner to add the S3 backend at runtime.
2016-03-02	importPaths(): Optionally add NARs to binary cache accessor	Eelco Dolstra	1	-2/+5
	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.
2016-02-25	Add NAR / Store accessor abstraction	Eelco Dolstra	1	-1/+11
	This is primary to allow hydra-queue-runner to extract files like "nix-support/hydra-build-products" from NARs in binary caches.
2016-02-24	Eliminate reserveSpace flag	Eelco Dolstra	1	-7/+3

2016-02-24	Move BinaryCacheStore / LocalBinaryCacheStore from Hydra	Eelco Dolstra	1	-2/+22
	So you can now do: $ NIX_REMOTE=file:///tmp/binary-cache nix-store -qR /nix/store/...
2016-02-16	Rename ValidPathInfo::hash -> narHash for consistency	Eelco Dolstra	1	-2/+2

2016-02-15	Expose the export magic value and move LocalStore::queryReferences to Store	Eelco Dolstra	1	-6/+9

2016-02-15	Add function to extract hash part of a store path	Eelco Dolstra	1	-0/+6

2016-02-11	Move addPermRoot into Store	Eelco Dolstra	1	-5/+4

2016-02-04	StoreAPI -> Store	Eelco Dolstra	1	-4/+4
	Calling a class an API is a bit redundant...
2016-02-04	Eliminate the "store" global variable	Eelco Dolstra	1	-18/+36
	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 hashes	Eelco Dolstra	1	-1/+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...)
2015-11-09	Add option to verify build determinism	Eelco Dolstra	1	-3/+11
	Passing "--option build-repeat <N>" will cause every build to be repeated N times. If the build output differs between any round, the build is rejected, and the output paths are not registered as valid. This is primarily useful to verify build determinism. (We already had a --check option to repeat a previously succeeded build. However, with --check, non-deterministic builds are registered in the DB. Preventing that is useful for Hydra to ensure that non-deterministic builds don't end up getting published at all.)
2015-10-06	nix-store --serve: Implement log size limit	Eelco Dolstra	1	-1/+2

2015-08-21	nix-collect-garbage: Revive --max-freed	Eelco Dolstra	1	-5/+4
	Fixes #609.
2015-07-20	Provide more detailed info about build status to hydra-queue-runner	Eelco Dolstra	1	-4/+14
	In particular, hydra-queue-runner can now distinguish between remote build / substitution / already-valid. For instance, if a path already existed on the remote side, we don't want to store a log file.
2015-07-17	Allow remote builds without sending the derivation closure	Eelco Dolstra	1	-0/+22
	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.
2015-06-02	Add a ‘verifyStore’ RPC	Ludovic Courtès	1	-0/+4
	Hello! The patch below adds a ‘verifyStore’ RPC with the same signature as the current LocalStore::verifyStore method. Thanks, Ludo’. >From aef46c03ca77eb6344f4892672eb6d9d06432041 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= <ludo@gnu.org> Date: Mon, 1 Jun 2015 23:17:10 +0200 Subject: [PATCH] Add a 'verifyStore' remote procedure call.
2015-03-25	addToStore(): Take explicit name argument	Eelco Dolstra	1	-10/+10
