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.
2012-11-19	nix-store -r: Don't quietly ignore missing paths	Eelco Dolstra	1	-0/+1

2012-10-03	When ‘--help’ is given, just run ‘man’ to show the manual page	Eelco Dolstra	1	-2/+1
	I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-10-02	Add a --repair flag to ‘nix-store -r’ to repair derivation outputs	Eelco Dolstra	1	-1/+3
	With this flag, if any valid derivation output is missing or corrupt, it will be recreated by using a substitute if available, or by rebuilding the derivation. The latter may use hash rewriting if chroots are not available.
2012-10-02	nix-store -r: Get rid of an unnecessary call to buildPaths/ensurePaths	Eelco Dolstra	1	-4/+4

2012-10-02	nix-store --verify: Add an option ‘--repair’ to repair all ↵	Eelco Dolstra	1	-2/+6
	missing/corrupt paths Also, return a non-zero exit code if errors remain after verifying/repairing.
2012-10-02	Add operation ‘nix-store --repair-path’	Eelco Dolstra	1	-0/+17
	This operation allows fixing corrupted or accidentally deleted store paths by redownloading them using substituters, if available. Since the corrupted path cannot be replaced atomically, there is a very small time window (one system call) during which neither the old (corrupted) nor the new (repaired) contents are available. So repairing should be used with some care on critical packages like Glibc.
2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra	1	-9/+12

2012-08-24	Include the output name in the GC root link	Eelco Dolstra	1	-3/+7
	Output names are now appended to resulting GC symlinks, e.g. by nix-build. For backwards compatibility, if the output is named "out", nothing is appended. E.g. doing "nix-build -A foo" on a derivation that produces outputs "out", "bin" and "dev" will produce symlinks "./result", "./result-bin" and "./result-dev", respectively.
2012-08-01	Drop the block count in the garbage collector	Eelco Dolstra	1	-5/+4

2012-08-01	nix-store --gc: Make ‘--max-freed 0’ do the right thing	Eelco Dolstra	1	-1/+1
	That is, delete almost nothing (it will still remove unused links from /nix/store/.links).
2012-07-30	Refactor settings processing	Eelco Dolstra	1	-35/+35
	Put all Nix configuration flags in a Settings object.
2012-07-26	Merge branch 'master' into no-manifests	Eelco Dolstra	1	-8/+2

2012-07-23	optimiseStore(): Use a content-addressed file store in /nix/store/.links	Eelco Dolstra	1	-8/+2
	optimiseStore() now creates persistent, content-addressed hard links in /nix/store/.links. For instance, if it encounters a file P with hash H, it will create a hard link P' = /nix/store/.link/<H> to P if P' doesn't already exist; if P' exist, then P is replaced by a hard link to P'. This is better than the previous in-memory map, because it had the tendency to unnecessarily replace hard links with a hard link to whatever happened to be the first file with a given hash it encountered. It also allows on-the-fly, incremental optimisation.
2012-07-11	Rename queryValidPaths() to queryAllValidPaths()	Eelco Dolstra	1	-1/+1

2012-06-27	nix-store -r: do substitutions in parallel	Eelco Dolstra	1	-7/+5
	I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2012-05-30	"nix-store -l": support compressed logs	Eelco Dolstra	1	-8/+33

2012-05-29	Reserve some disk space for the garbage collector	Eelco Dolstra	1	-1/+1
	We can't open a SQLite database if the disk is full. Since this prevents the garbage collector from running when it's most needed, we reserve some dummy space that we can free just before doing a garbage collection. This actually revives some old code from the Berkeley DB days. Fixes #27.
2012-03-26	Remove the --max-links GC option	Eelco Dolstra	1	-1/+0
	We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra	1	-1/+1

2012-01-17	* Added a command ‘nix-store --print-env $drvpath’ that prints out the	Eelco Dolstra	1	-0/+35
	environment of the given derivation in a format that can be sourced by the shell, e.g. $ eval "$(nix-store --print-env $(nix-instantiate /etc/nixos/nixpkgs -A pkg))" $ NIX_BUILD_TOP=/tmp $ source $stdenv/setup This is especially useful to reproduce the environment used to build a package outside of its builder for development purposes. TODO: add a nix-build option to do the above and fetch the dependencies of the derivation as well.
2011-12-30	* Support multiple outputs in nix-store (specifically the ‘--query’	Eelco Dolstra	1	-43/+63
	and ‘--realise’ actions).
2011-12-16	* importPath() -> importPaths(). Because of buffering of the input	Eelco Dolstra	1	-6/+4
	stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it.
2011-12-02	* Move parseHash16or32 into libutil, and use in nix-hash.	Eelco Dolstra	1	-8/+0

2011-11-23	* Add an API function exportPaths() that provides the functionality of	Eelco Dolstra	1	-5/+1
	‘nix-store --export’. * Add a Perl module that provides the functionality of ‘nix-copy-closure --to’. This is used by build-remote.pl so it no longer needs to start a separate nix-copy-closure process. Also, it uses the Perl API to do the export, so it doesn't need to start a separate nix-store process either. As a result, nix-copy-closure and build-remote.pl should no longer fail on very large closures due to an "Argument list too long" error. (Note that having very many dependencies in a single derivation can still fail because the environment can become too large. Can't be helped though.)
2011-09-06	* Added a command ‘nix-store --verify-paths PATHS’ to check whether	Eelco Dolstra	1	-1/+25
	the contents of any of the given store paths have been modified. E.g. $ nix-store --verify-path $(nix-store -qR /var/run/current-system) path `/nix/store/m2smyiwbxidlprfxfz4rjlvz2c3mg58y-etc' was modified! expected hash `fc87e271c5fdf179b47939b08ad13440493805584b35e3014109d04d8436e7b8', got `20f1a47281b3c0cbe299ce47ad5ca7340b20ab34246426915fce0ee9116483aa' All paths are checked; the exit code is 1 if any path has been modified, 0 otherwise.
