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	1	-2/+32
	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.

2014-08-13	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	1	-1/+12

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	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	1	-5/+32
	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	1	-43/+53
	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	1	-3/+26
	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.

2013-03-07	Prevent config.h from being clobbered	Eelco Dolstra	1	-39/+38

2013-02-26	Security: Don't allow builders to change permissions on files they don't own	Eelco Dolstra	1	-8/+2
	It turns out that in multi-user Nix, a builder may be able to do ln /etc/shadow $out/foo Afterwards, canonicalisePathMetaData() will be applied to $out/foo, causing /etc/shadow's mode to be set to 444 (readable by everybody but writable by nobody). That's obviously Very Bad. Fortunately, this fails in NixOS's default configuration because /nix/store is a bind mount, so "ln" will fail with "Invalid cross-device link". It also fails if hard-link restrictions are enabled, so a workaround is: echo 1 > /proc/sys/fs/protected_hardlinks The solution is to check that all files in $out are owned by the build user. This means that innocuous operations like "ln ${pkgs.foo}/some-file $out/" are now rejected, but that already failed in chroot builds anyway.
2013-01-30	Support the colonies	Eelco Dolstra	1	-3/+3

2013-01-22	Correctly handle missing logs	Eelco Dolstra	1	-1/+3

2013-01-17	Store build logs in /nix/var/log/nix/drvs/<XX>	Eelco Dolstra	1	-27/+32
	...where <XX> is the first two characters of the derivation. Otherwise /nix/var/log/nix/drvs may become so large that we run into all sorts of weird filesystem limits/inefficiences. For instance, ext3/ext4 filesystems will barf with "ext4_dx_add_entry:1551: Directory index full!" once you hit a few million files.
2012-12-20	nix-store -q --roots: Respect the gc-keep-outputs/gc-keep-derivations settings	Eelco Dolstra	1	-1/+2
	So if a path is not garbage solely because it's reachable from a root due to the gc-keep-outputs or gc-keep-derivations settings, ‘nix-store -q --roots’ now shows that root.
2012-11-26	Make "nix-build -A <derivation>.<output>" do the right thing	Eelco Dolstra	1	-5/+15
	For example, given a derivation with outputs "out", "man" and "bin": $ nix-build -A pkg produces ./result pointing to the "out" output; $ nix-build -A pkg.man produces ./result-man pointing to the "man" output; $ nix-build -A pkg.all produces ./result, ./result-man and ./result-bin; $ nix-build -A pkg.all -A pkg2 produces ./result, ./result-man, ./result-bin and ./result-2.
2012-11-20	nix-store -r: Add ‘--ignore-unknown’ flag	Eelco Dolstra	1	-9/+25
	This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line.
