2014-06-12	Drop ImportError and FindError	Eelco Dolstra	2	-6/+0
	We're not catching these anywhere.
2014-06-12	findFile: Realise the context of the path attributes	Shea Levy	2	-18/+45

2014-06-12	Share code between scopedImport and import	Shea Levy	1	-42/+44
	In addition to reducing duplication, this fixes both import from derivation and import of derivation for scopedImport
2014-06-10	== operator: Ignore string context	Eelco Dolstra	2	-12/+3
	There really is no case I can think of where taking the context into account is useful. Mostly it's just very inconvenient.
2014-06-10	Report daemon OOM better	Eelco Dolstra	2	-9/+19
	When copying a large path causes the daemon to run out of memory, you now get: error: Nix daemon out of memory instead of: error: writing to file: Broken pipe
2014-06-10	Print a warning when loading a large path into memory	Eelco Dolstra	3	-4/+33
	I.e. if you have a derivation with src = ./huge-directory; you'll get a warning that this is not a good idea.
2014-06-02	nix-env -qa --json: Generate valid JSON even if there are invalid meta attrs	Eelco Dolstra	1	-2/+3

2014-05-29	Sort nixPath attributes	Eelco Dolstra	1	-0/+1

2014-05-26	Use std::unordered_set	Eelco Dolstra	3	-21/+5

2014-05-26	Remove ExprBuiltin	Eelco Dolstra	4	-35/+8
	It's slower than ExprVar since it doesn't compute a static displacement. Since we're not using the throw primop in the implementation of <...> anymore, it's also not really needed.
2014-05-26	Make the Nix search path declarative	Eelco Dolstra	5	-16/+49
	Nix search path lookups like <nixpkgs> are now desugared to ‘findFile nixPath <nixpkgs>’, where ‘findFile’ is a new primop. Thus you can override the search path simply by saying let nixPath = [ { prefix = "nixpkgs"; path = "/my-nixpkgs"; } ]; in ... <nixpkgs> ... In conjunction with ‘scopedImport’ (commit c273c15cb13bb86420dda1e5341a4e19517532b5), the Nix search path can be propagated across imports, e.g. let overrides = { nixPath = [ ... ] ++ builtins.nixPath; import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; builtins = builtins // overrides; }; in scopedImport overrides ./nixos
2014-05-26	Ensure that -I flags get included in nixPath	Eelco Dolstra	7	-17/+32
	Also fixes #261.
2014-05-26	Add constant ‘nixPath’	Eelco Dolstra	1	-0/+11
	It contains the Nix expression search path as a list of { prefix, path } sets, e.g. [ { path = "/nix/var/nix/profiles/per-user/root/channels/nixos"; prefix = ""; } { path = "/etc/nixos/configuration.nix"; prefix = "nixos-config"; } { path = "/home/eelco/Dev/nix/inst/share/nix/corepkgs"; prefix = "nix"; } ]
2014-05-26	Add primop ‘scopedImport’	Eelco Dolstra	4	-3/+34
	‘scopedImport’ works like ‘import’, except that it takes a set of attributes to be added to the lexical scope of the expression, essentially extending or overriding the builtin variables. For instance, the expression scopedImport { x = 1; } ./foo.nix where foo.nix contains ‘x’, will evaluate to 1. This has a few applications: * It allows getting rid of function argument specifications in package expressions. For instance, a package expression like: { stdenv, fetchurl, libfoo }: stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } can now we written as just stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } and imported in all-packages.nix as: bar = scopedImport pkgs ./bar.nix; So whereas we once had dependencies listed in three places (buildInputs, the function, and the call site), they now only need to appear in one place. * It allows overriding builtin functions. For instance, to trace all calls to ‘map’: let overrides = { map = f: xs: builtins.trace "map called!" (map f xs); # Ensure that our override gets propagated by calls to # import/scopedImport. import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; # Also update ‘builtins’. builtins = builtins // overrides; }; in scopedImport overrides ./bla.nix * Similarly, it allows extending the set of builtin functions. For instance, during Nixpkgs/NixOS evaluation, the Nixpkgs library functions could be added to the default scope. There is a downside: calls to scopedImport are not memoized, unlike import. So importing a file multiple times leads to multiple parsings / evaluations. It would be possible to construct the AST only once, but that would require careful handling of variables/environments.
2014-05-26	Shut up some signedness warnings	Eelco Dolstra	1	-2/+2

2014-05-23	Ugly hack to allow --argstr values starting with a dash	Eelco Dolstra	1	-0/+7
	Fixes #265.
2014-05-21	nix-store -l: Fetch build logs from the Internet	Eelco Dolstra	6	-4/+35
	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	Provide a more useful error message when a dynamic attr lookup fails	Shea Levy	1	-2/+10

2014-05-15	lvlInfo -> lvlTalkative	Eelco Dolstra	1	-1/+1

2014-05-15	nix-store --optimise: Remove bogus statistics	Eelco Dolstra	3	-14/+9

2014-05-15	Remove tab	Eelco Dolstra	1	-2/+2

2014-05-15	Merge branch 'master' of github.com:wmertens/nix	Eelco Dolstra	2	-8/+80

2014-05-15	Shortcut store files before lstat	Wout Mertens	2	-9/+37
	readdir() already returns the inode numbers, so we don't need to call lstat to know if a file was already linked or not.
2014-05-14	Use the inodes given by readdir directly	Wout Mertens	2	-21/+25

2014-05-13	Preload linked hashes to speed up lookups	Wout Mertens	2	-10/+41
	By preloading all inodes in the /nix/store/.links directory, we can quickly determine of a hardlinked file was already linked to the hashed links. This is tolerant of removing the .links directory, it will simply recalculate all hashes in the store.
2014-05-13	nix-instantiate --eval: Apply auto-arguments if the result is a function	Eelco Dolstra	1	-5/+10
	Fixes #254.
2014-05-10	Shortcut already-hardlinked files	wmertens	1	-1/+10
	If an inode in the Nix store has more than 1 link, it probably means that it was linked into .links/ by us. If so, skip. There's a possibility that something else hardlinked the file, so it would be nice to be able to override this. Also, by looking at the number of hardlinks for each of the files in .links/, you can get deduplication numbers and space savings.
2014-05-02	Set up directories and permissions for multi-user install automatically	Eelco Dolstra	1	-1/+28
	This automatically creates /nix/var/nix/profiles/per-user and sets the permissions/ownership on /nix/store to 1775 and root:nixbld.
2014-05-02	Set build-max-jobs to the number of available cores by default	Eelco Dolstra	1	-0/+5
	More zero configuration.
2014-05-02	When running as root, use build users by default	Eelco Dolstra	1	-0/+1
	This removes the need to have a nix.conf, and prevents people from accidentally running Nix builds as root.
2014-04-15	nix-env: Minor change to '--delete-generations Nd' semantics	Ricardo M. Correia	1	-4/+10
	The option '--delete-generations Nd' deletes all generations older than N days. However, most likely the user does not want to delete the generation that was active N days ago. For example, say that you have these 3 generations: 1: <30 days ago> 2: <15 days ago> 3: <1 hour ago> If you do --delete-generations 7d (say, as part of a cron job), most likely you still want to keep generation 2, i.e. the generation that was active 7 days ago (and for most of the past 7 days, in fact). This patch fixes this issue. Note that this also affects 'nix-collect-garbage --delete-older-than Nd'. Thanks to @roconnor for noticing the issue!
2014-04-08	If a .drv cannot be parsed, show its path	Eelco Dolstra	7	-10/+22
	Otherwise you just get ‘expected string `Derive(['’ which isn't very helpful.

2014-04-04	Show position info in Boolean operations	Eelco Dolstra	5	-31/+28

2014-04-04	Show position info in string concatenation / addition errors	Eelco Dolstra	7	-45/+63

2014-04-04	forceString: Show position info	Eelco Dolstra	6	-30/+46

2014-04-04	forceAttrs: Show position info	Eelco Dolstra	5	-14/+23

2014-04-04	forceList: Show position info	Eelco Dolstra	5	-24/+35

2014-04-04	forceInt: Show position info	Eelco Dolstra	3	-11/+11

2014-04-04	Pass position information to primop calls	Eelco Dolstra	4	-104/+104
	For example: error: `tail' called on an empty list, at /home/eelco/Dev/nixpkgs/pkgs/applications/misc/hello/ex-2/default.nix:13:7
2014-04-04	Remove unnecessary quotes around file names	Eelco Dolstra	1	-1/+1

2014-04-04	Include position info in function application	Eelco Dolstra	7	-22/+45
	This allows error messages like: error: the anonymous function at `/etc/nixos/configuration.nix:1:1' called without required argument `foo', at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/lib/modules.nix:77:59'
2014-04-03	Fix compile errors on Illumos	Danny Wilson	3	-0/+9

2014-04-03	Tweak error message	Eelco Dolstra	1	-1/+1

2014-04-03	Make sure /dev/pts/ptmx is world-writable	Ludovic Courtès	1	-0/+4
	While running Python 3’s test suite, we noticed that on some systems /dev/pts/ptmx is created with permissions 0 (that’s the case with my Nixpkgs-originating 3.0.43 kernel, but someone with a Debian-originating 3.10-3 reported not having this problem.) There’s still the problem that people without CONFIG_DEVPTS_MULTIPLE_INSTANCES=y are screwed (as noted in build.cc), but I don’t see how we could work around it.
2014-04-01	Fix potential segfault	Eelco Dolstra	1	-2/+3
	The newEnv variable was accessed (via the dynamicEnv) pointer after it had gone out of scope. Fixes #234.
2014-03-30	nix-env: Add support for --delete-generations 15d	Ricardo M. Correia	1	-2/+17
	It will delete all generations older than the specified number of days.
2014-03-30	boost::shared_ptr -> std::shared_ptr	Eelco Dolstra	12	-1467/+36

2014-03-29	Drop pointless #include	Eelco Dolstra	1	-2/+0

2014-03-29	Fix potential segfault in waitForInput()	Eelco Dolstra	1	-3/+5
	Since the addition of build-max-log-size, a call to handleChildOutput() can result in cancellation of a goal. This invalidated the "j" iterator in the waitForInput() loop, even though it was still used afterwards. Likewise for the maxSilentTime handling. Probably fixes #231. At least it gets rid of the valgrind warnings.
