2016-09-21	printMsg(lvlError, ...) -> printError(...) etc.	Eelco Dolstra	1	-1/+1

2016-09-21	Some notational convenience for formatting strings	Eelco Dolstra	1	-1/+1
	We can now write throw Error("file '%s' not found", path); instead of throw Error(format("file '%s' not found") % path); and similarly printError("file '%s' not found", path); instead of printMsg(lvlError, format("file '%s' not found") % path);
2016-09-16	Make computeFSClosure() single-threaded again	Eelco Dolstra	1	-30/+34
	The fact that queryPathInfo() is synchronous meant that we needed a thread for every concurrent binary cache lookup, even though they end up being handled by the same download thread. Requiring hundreds of threads is not a good idea. So now there is an asynchronous version of queryPathInfo() that takes a callback function to process the result. Similarly, enqueueDownload() now takes a callback rather than returning a future. Thus, a command like nix path-info --store https://cache.nixos.org/ -r /nix/store/slljrzwmpygy1daay14kjszsr9xix063-nixos-16.09beta231.dccf8c5 that returns 4941 paths now takes 1.87s using only 2 threads (the main thread and the downloader thread). (This is with a prewarmed CloudFront.)
2016-08-10	Mark content-addressed paths in the Nix database and in .narinfo	Eelco Dolstra	1	-0/+1
	This allows such paths to be imported without signatures.
2016-08-10	RemoteStore / nix-daemon: Drop support for Nix < 1.0	Eelco Dolstra	1	-19/+15

2016-07-11	Modernize AutoCloseFD	Shea Levy	1	-6/+6

2016-06-09	Use O_CLOEXEC in most places	Eelco Dolstra	1	-1/+5

2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra	1	-20/+21

2016-05-31	nix-copy-closure / build-remote.pl: Disable signature checking	Eelco Dolstra	1	-1/+2
	This restores the Nix 1.11 behaviour.
2016-05-04	Do compression in a sink	Eelco Dolstra	1	-1/+1

2016-05-04	Add a Store::addToStore() variant that accepts a NAR	Eelco Dolstra	1	-19/+6
	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	-6/+3

2016-04-29	Allow parameters in store URIs	Eelco Dolstra	1	-0/+6
	This is to allow store-specific configuration, e.g. s3://my-cache?compression=bzip2&secret-key=/path/to/key.
2016-04-25	Show the log tail when a build fails	Eelco Dolstra	1	-1/+1
	If --no-build-output is given (which will become the default for the "nix" command at least), show the last 10 lines of the build output if the build fails.
2016-04-25	Remove --print-build-trace	Eelco Dolstra	1	-1/+1
	This was added to support Hydra, but Hydra no longer uses it.
2016-04-25	Improved logging abstraction	Eelco Dolstra	1	-6/+4
	This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-04-20	RemoteStore: Propagate InvalidPath exceptions from the daemon	Eelco Dolstra	1	-1/+12

2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra	1	-1/+0
	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	-44/+18
	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	-17/+1
	This feature was implemented for Hydra, but Hydra no longer uses it.
2016-04-05	Add "nix copy-sigs" command	Eelco Dolstra	1	-0/+9
	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	LocalStore: Keep track of ultimately trusted paths	Eelco Dolstra	1	-0/+4
	These are content-addressed paths or outputs of locally performed builds. They are trusted even if they don't have signatures, so "nix verify-paths" won't complain about them.
2016-03-23	Drop support for daemon socket path >= 108 characters	Eelco Dolstra	1	-15/+3
	Doing a chdir() is a bad idea in multi-threaded programs, leading to failures such as error: cannot connect to daemon at ‘/nix/var/nix/daemon-socket/socket’: No such file or directory Since Linux doesn't have a connectat() syscall like FreeBSD, there is no way we can support this in a race-free way.
2016-03-22	Don't overload dumpPath()	Eelco Dolstra	1	-1/+1

2016-03-21	Add Store::dumpPath() method	Eelco Dolstra	1	-1/+1
	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	-1/+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	-2/+2

2016-02-24	Remove bad daemon connections from the pool	Eelco Dolstra	1	-1/+5
	This is necessary for long-running processes like hydra-queue-runner: if a nix-daemon worker is killed, we need to stop reusing that connection.
2016-02-23	Pool<T>: Allow a maximum pool size	Eelco Dolstra	1	-15/+15

2016-02-23	RemoteStore: Make thread-safe	Eelco Dolstra	1	-226/+221
	This allows a RemoteStore object to be used safely from multiple threads concurrently. It will make multiple daemon connections if necessary. Note: pool.hh and sync.hh have been copied from the Hydra source tree.
2016-02-16	Rename ValidPathInfo::hash -> narHash for consistency	Eelco Dolstra	1	-1/+1

2016-01-31	Use the daemon when we don't have write access to the Nix database	Eelco Dolstra	1	-8/+2

2015-12-02	daemon: Add 'buildMode' parameter to 'buildPaths' RPC	Ludovic Courtès	1	-3/+9

2015-09-03	Implement buildDerivation() via the daemon	Eelco Dolstra	1	-1/+9

2015-07-20	More cleanup	Eelco Dolstra	1	-102/+63

2015-07-17	OCD: foreach -> C++11 ranged for	Eelco Dolstra	1	-14/+14

2015-07-17	Allow remote builds without sending the derivation closure	Eelco Dolstra	1	-0/+7
	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/+10
	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	-2/+2

2014-12-14	Merge branch 'cygwin-master' of https://github.com/ternaris/nix	Eelco Dolstra	1	-0/+1

2014-12-13	Better error message	Eelco Dolstra	1	-1/+1

2014-12-12	Silence some warnings on GCC 4.9	Eelco Dolstra	1	-1/+1

2014-12-09	Explicitly include required C headers	Marko Durkovic	1	-0/+1

2014-10-31	Improve error message if the daemon worker fails to start	Eelco Dolstra	1	-2/+1

2014-09-01	Add an 'optimiseStore' remote procedure call.	Ludovic Courtès	1	-0/+7

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	1	-3/+3

2014-07-25	nix-daemon: Pass on the user's $SSH_AUTH_SOCK to the SSH substituter	Eelco Dolstra	1	-0/+2

2014-07-23	Remove dead code	Eelco Dolstra	1	-2/+0

2014-07-14	build-remote.pl: Fix building multiple output derivations	Eelco Dolstra	1	-1/+0
	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	1	-0/+1
	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.
