2014-07-10	nix-copy-closure: Fix race condition	Eelco Dolstra	4	-60/+136
	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.

2014-06-24	Only add the importNative primop if the ↵	Shea Levy	3	-1/+7
	allow-arbitrary-code-during-evaluation option is true (default false)
2014-06-17	Add importNative primop	Shea Levy	2	-0/+44
	This can be used to import a dynamic shared object and return an arbitrary value, including new primops. This can be used both to test new primops without having to recompile nix every time, and to build specialized primops that probably don't belong upstream (e.g. a function that calls out to gpg to decrypt a nixops secret as-needed). The imported function should initialize the Value & as needed. A single import can define multiple values by creating an attrset or list, of course. An example initialization function might look like: extern "C" void initialize(nix::EvalState & state, nix::Value & v) { v.type = nix::tPrimOp; v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun")); } Then `builtins.importNative ./example.so "initialize"` will evaluate to the primop defined in the myFun function.
2014-06-12	Don't use member initialisers	Eelco Dolstra	1	-4/+4
	They're a little bit too recent (only supported since GCC 4.7). http://hydra.nixos.org/build/11851475
2014-06-12	Fix bogus warnings about dumping large paths	Eelco Dolstra	1	-2/+2
	Also, yay for C++11 non-static initialisers.
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
2014-06-12	Add autoloads, make code more concise & idiomatic	Steve Purcell	1	-78/+55
	- Use define-derived-mode to declare nix-mode - Use autoloads to ensure nix-mode is usable (and enabled) without needing `require` - Use set + make-local-variable instead of longer 2-step equivalent
2014-06-10	== operator: Ignore string context	Eelco Dolstra	3	-13/+4
	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	Fix test	Eelco Dolstra	2	-2/+2

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

2014-05-26	Use std::unordered_set	Eelco Dolstra	4	-27/+5

2014-05-26	nix-build: --add-root also takes 1 parameter	Aristid Breitkreuz	1	-1/+1

2014-05-26	dev-shell is a bash script, not sh	Sönke Hahn	1	-1/+1
	'type -p' does not work in e.g. dash
2014-05-26	Rephrase @ operator description	Adam Szkoda	1	-4/+3

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	7	-17/+51
	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	8	-18/+33
	Also fixes #261.
2014-05-26	Add constant ‘nixPath’	Eelco Dolstra	3	-2/+20
	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	8	-3/+50
	‘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.
2014-05-22	Disable parallel.sh test	Eelco Dolstra	1	-1/+2
	It breaks randomly: http://hydra.nixos.org/build/11152871
2014-05-21	nix-store -l: Fetch build logs from the Internet	Eelco Dolstra	9	-93/+144
	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	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

2014-05-14	Remove redundant code	Eelco Dolstra	1	-1/+1

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.
