2016-04-19	Move path info caching from BinaryCacheStore to Store	Eelco Dolstra	3	-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 caching	Eelco Dolstra	1	-22/+0
	This feature was implemented for Hydra, but Hydra no longer uses it.
2016-03-22	Don't overload dumpPath()	Eelco Dolstra	1	-1/+1

2016-03-21	Add Store::dumpPath() method	Eelco Dolstra	1	-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 accessor	Eelco Dolstra	1	-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 flag	Eelco Dolstra	1	-1/+1

2016-02-16	Rename ValidPathInfo::hash -> narHash for consistency	Eelco Dolstra	1	-6/+6

2016-02-11	Move addPermRoot into Store	Eelco Dolstra	1	-2/+2

2016-02-04	More of the same	Eelco Dolstra	5	-13/+13

2016-02-04	StoreAPI -> Store	Eelco Dolstra	5	-10/+10
	Calling a class an API is a bit redundant...
2016-02-04	Eliminate the "store" global variable	Eelco Dolstra	5	-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 hashes	Eelco Dolstra	1	-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...)

2015-07-23	--version: Print some config info	Eelco Dolstra	1	-1/+7
	Such as whether Nix is built with signed binary cache support, and the location of the configuration file.
2015-07-20	More cleanup	Eelco Dolstra	1	-16/+11

2015-07-17	OCD: foreach -> C++11 ranged for	Eelco Dolstra	1	-148/+142

2015-07-17	Allow remote builds without sending the derivation closure	Eelco Dolstra	2	-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.

2015-05-13	Fix "error: deriver of path ‘’ is not known"	Eelco Dolstra	1	-6/+5

2015-03-25	addToStore(): Take explicit name argument	Eelco Dolstra	1	-4/+4

2015-03-04	Add option to hide display of missing paths	Eelco Dolstra	1	-1/+2

2015-02-18	nix-store --generate-binary-cache-key: Write key to disk	Eelco Dolstra	1	-4/+8
	This ensures proper permissions for the secret key.
2015-02-10	Make libsodium an optional dependency	Eelco Dolstra	1	-0/+6

2015-02-10	Add base64 encoder/decoder	Eelco Dolstra	1	-8/+2

2015-02-04	Use libsodium instead of OpenSSL for binary cache signing	Eelco Dolstra	2	-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.
2014-12-12	Ensure we're writing to stderr in the builder	Eelco Dolstra	1	-1/+1
	http://hydra.nixos.org/build/17862041
2014-10-14	nix-store -q: Check for conflicting flags	Eelco Dolstra	1	-4/+12
	Fixes #364.
2014-09-01	Add an 'optimiseStore' remote procedure call.	Ludovic Courtès	1	-19/+1

2014-08-20	Use pager for more commands	Eelco Dolstra	1	-0/+2

2014-08-13	Refactor option handling	Eelco Dolstra	1	-93/+92

2014-07-24	nix-copy-closure: Drop --bzip2, --xz, --show-progress	Eelco Dolstra	1	-32/+1
	These are too difficult to implement via nix-store --serve. ‘--show-progress’ could be re-implemented fairly easily via a sink/source wrapper class.
2014-07-24	Implement nix-copy-closure --from via nix-store --serve	Eelco Dolstra	2	-1/+13

2014-07-24	build-remote.pl: Be less verbose on failing builds	Eelco Dolstra	1	-4/+4

2014-07-24	nix-store --serve: Only monitor stdin during builds	Eelco Dolstra	1	-2/+2
	Other operations cannot hang indefinitely (except when we're reading from stdin, in which case we'll notice a client disconnect). But monitoring works badly during compressed imports, since there the client can close the connection before we've sent an ack. http://hydra.nixos.org/build/12711638
2014-07-23	Pass -pthread only for programs that need it	Eelco Dolstra	1	-1/+1

2014-07-23	nix-store --serve: Monitor for client disconnects	Eelco Dolstra	1	-0/+3
	This is necessary because build-remote.pl now builds via ‘nix-store --serve’. So if a build hangs without writing to stdout/stderr, and the client disconnects, then we need to detect that.
2014-07-14	build-remote.pl: Fix building multiple output derivations	Eelco Dolstra	1	-1/+3
	We were importing paths without sorting them topologically, leading to "path is not valid" errors. See e.g. http://hydra.nixos.org/build/12451761
2014-07-11	build-remote.pl: Use ‘nix-store --serve’ on the remote side	Eelco Dolstra	2	-5/+34
	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.
2014-07-10	nix-copy-closure -s: Do substitutions via ‘nix-store --serve’	Eelco Dolstra	1	-0/+29
	This means we no longer need an SSH master connection, since we only execute a single command on the remote host.
2014-07-10	Refactoring: Move all fork handling into a higher-order function	Eelco Dolstra	1	-21/+8
	C++11 lambdas ftw.
2014-07-10	nix-copy-closure: Restore compression and the progress viewer	Eelco Dolstra	1	-2/+47

2014-07-10	nix-copy-closure: Fix race condition	Eelco Dolstra	2	-53/+58
	There is a long-standing race condition when copying a closure to a remote machine, particularly affecting build-remote.pl: the client first asks the remote machine which paths it already has, then copies over the missing paths. If the garbage collector kicks in on the remote machine between the first and second step, the already-present paths may be deleted. The missing paths may then refer to deleted paths, causing nix-copy-closure to fail. The client now performs both steps using a single remote Nix call (using ‘nix-store --serve’), locking all paths in the closure while querying. I changed the --serve protocol a bit (getting rid of QueryCommand), so this breaks the SSH substituter from older versions. But it was marked experimental anyway. Fixes #141.
