2015-07-23	--version: Print some config info	Eelco Dolstra	1	-1/+7

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.

2015-03-25	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

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

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	2	-26/+26

2014-08-20	nix-store -l: Automatically pipe output into $PAGER	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.
2014-07-10	Fix security hole in ‘nix-store --serve’	Eelco Dolstra	1	-1/+1
	Since it didn't check that the path received from the client is a store path, the client could dump any path in the file system.
2014-05-21	nix-store -l: Fetch build logs from the Internet	Eelco Dolstra	2	-3/+28
	If a build log is not available locally, then ‘nix-store -l’ will now try to download it from the servers listed in the ‘log-servers’ option in nix.conf. For instance, if you have: log-servers = http://hydra.nixos.org/log then it will try to get logs from http://hydra.nixos.org/log/<base name of the store path>. So you can do things like: $ nix-store -l $(which xterm) and get a log even if xterm wasn't built locally.
2014-05-15	nix-store --optimise: Remove bogus statistics	Eelco Dolstra	1	-4/+2

2014-02-26	nix-store -r: Respect --add-root for non-derivations	Eelco Dolstra	1	-1/+9
	Fixes #68. Fixes #117.
2014-02-18	Add a flag ‘--check’ to verify build determinism	Eelco Dolstra	1	-3/+4
	The flag ‘--check’ to ‘nix-store -r’ or ‘nix-build’ will cause Nix to redo the build of a derivation whose output paths are already valid. If the new output differs from the original output, an error is printed. This makes it easier to test if a build is deterministic. (Obviously this cannot catch all sources of non-determinism, but it catches the most common one, namely the current time.) For example: $ nix-build '<nixpkgs>' -A patchelf ... $ nix-build '<nixpkgs>' -A patchelf --check error: derivation `/nix/store/1ipvxsdnbhl1rw6siz6x92s7sc8nwkkb-patchelf-0.6' may not be deterministic: hash mismatch in output `/nix/store/4pc1dmw5xkwmc6q3gdc9i5nbjl4dkjpp-patchelf-0.6.drv' The --check build fails if not all outputs are valid. Thus the first call to nix-build is necessary to ensure that all outputs are valid. The current outputs are left untouched: the new outputs are either put in a chroot or diverted to a different location in the store using hash rewriting.
2014-02-17	nix-store --gc --max-freed: Support a unit specifier	Eelco Dolstra	1	-1/+1
	E.g. "--max-freed 10G" means "free ten gigabytes".

2014-02-08	Add the nix-store --serve command	Shea Levy	1	-0/+20
	This is essentially the substituter API operating on the local store, which will be used by the ssh substituter. It runs in a loop rather than just taking one command so that in the future nix will be able to keep one connection open for multiple instances of the substituter.
