2015-06-01	Fix fetchurl/fetchTarball	Eelco Dolstra	1	-1/+2

2015-06-01	readFile: Check against nul bytes	Eelco Dolstra	1	-1/+4

2015-05-05	Allow URLs in the Nix search path	Eelco Dolstra	1	-85/+3
	E.g. to install "hello" from the latest Nixpkgs: $ nix-build '<nixpkgs>' -A hello -I nixpkgs=https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz Or to install a specific version of NixOS: $ nixos-rebuild switch -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz
2015-04-09	Use cached result if there is a network error	Eelco Dolstra	1	-7/+12

2015-04-09	Move curl stuff into a separate file	Eelco Dolstra	1	-112/+6

2015-04-09	Implement a TTL on cached fetchurl/fetchTarball results	Eelco Dolstra	1	-13/+24
	This is because we don't want to do HTTP requests on every evaluation, even though we can prevent a full redownload via the cached ETag. The default is one hour.
2015-04-09	Implement caching of fetchurl/fetchTarball results	Eelco Dolstra	1	-14/+119
	ETags are used to prevent redownloading unchanged files.
2015-03-25	Add fetchTarball builtin	Eelco Dolstra	1	-0/+119
	This function downloads and unpacks the given URL at evaluation time. This is primarily intended to make it easier to deal with Nix expressions that have external dependencies. For instance, to fetch Nixpkgs 14.12: with import (fetchTarball https://github.com/NixOS/nixpkgs-channels/archive/nixos-14.12.tar.gz) {}; Or to fetch a specific revision: with import (fetchTarball https://github.com/NixOS/nixpkgs/archive/2766a4b44ee6eafae03a042801270c7f6b8ed32a.tar.gz) {}; This patch also adds a ‘fetchurl’ builtin that downloads but doesn't unpack its argument. Not sure if it's useful though.
2015-03-25	addToStore(): Take explicit name argument	Eelco Dolstra	1	-1/+1

2015-03-24	Don't rely on __noChroot for corepkgs	Eelco Dolstra	1	-2/+5
	This doesn't work anymore if the "strict" chroot mode is enabled. Instead, add Nix's store path as a dependency. This ensures that its closure is present in the chroot.
2015-03-06	Fix typos: s/the the/the/	Daniel Hahler	1	-1/+1

2015-02-23	Add restricted evaluation mode	Eelco Dolstra	1	-7/+21
	If ‘--option restrict-eval true’ is given, the evaluator will throw an exception if an attempt is made to access any file outside of the Nix search path. This is primarily intended for Hydra, where we don't want people doing ‘builtins.readFile ~/.ssh/id_dsa’ or stuff like that.
2015-02-05	Remove tab	Eelco Dolstra	1	-1/+1

2015-01-29	Merge remote-tracking branch 'shlevy/baseNameOf-no-copy'	Shea Levy	1	-1/+1
	baseNameOf: Don't copy paths to the store first
2015-01-09	Fix builtins.readDir on XFS	Eelco Dolstra	1	-1/+1
	The DT_UNKNOWN fallback code was getting the type of the wrong path, causing readDir to report "directory" as the type of every file. Reported by deepfire on IRC.
2015-01-07	Show position info for failing <...> lookups	Eelco Dolstra	1	-1/+1

2014-12-12	Remove canary stuff	Eelco Dolstra	1	-27/+0

2014-12-10	builtins.readFile: realise context associated with the path	Shea Levy	1	-2/+6

2014-12-02	Allow external code using libnixexpr to add types	Shea Levy	1	-0/+3
	Code that links to libnixexpr (e.g. plugins loaded with importNative, or nix-exec) may want to provide custom value types and operations on values of those types. For example, nix-exec is currently using sets where a custom IO value type would be more appropriate. This commit provides a generic hook for such types in the form of tExternal and the ExternalBase virtual class, which contains all functions necessary for libnixexpr's type-polymorphic functions (e.g. `showType`) to be implemented.
2014-11-25	Add a primop for regular expression pattern matching	Eelco Dolstra	1	-1/+29
	The function ‘builtins.match’ takes a POSIX extended regular expression and an arbitrary string. It returns ‘null’ if the string does not match the regular expression. Otherwise, it returns a list containing substring matches corresponding to parenthesis groups in the regex. The regex must match the entire string (i.e. there is an implied "^<pat>$" around the regex). For example: match "foo" "foobar" => null match "foo" "foo" => [] match "f(o+)(.)" "foooobar" => ["oooo" "bar"] match "(./)?([^/])" "/dir/file.nix" => ["/dir/" "file.nix"] match "(./)?([^/])" "file.nix" => [null "file.nix"] The following example finds all regular files with extension .nix or .patch underneath the current directory: let findFiles = pat: dir: concatLists (mapAttrsToList (name: type: if type == "directory" then findFiles pat (dir + "/" + name) else if type == "regular" && match pat name != null then [(dir + "/" + name)] else []) (readDir dir)); in findFiles ".\\.(nix\|patch)" (toString ./.)
2014-11-25	forceString(): Accept pos argument	Eelco Dolstra	1	-2/+2

2014-11-20	import derivation: cleanup	Shea Levy	1	-8/+11
	Before this there was a bug where a `find` was being called on a not-yet-sorted set. The code was just a mess before anyway, so I cleaned it up while fixing it.
2014-11-15	realiseContext: Handle all context types	Shea Levy	1	-2/+2
	Avoids an assertion
2014-10-18	baseNameOf: Don't copy paths to the store first	Shea Levy	1	-1/+1

2014-10-17	Export realiseContext in libnixexpr	Shea Levy	1	-9/+3
	Useful for importNative plugins
2014-10-04	Add primop ‘catAttrs’	Eelco Dolstra	1	-0/+30

2014-10-04	Add primop ‘attrValues’	Eelco Dolstra	1	-1/+23

2014-10-04	Tweak	Eelco Dolstra	1	-1/+1

2014-10-03	Remove some duplicate code	Eelco Dolstra	1	-15/+8

2014-10-03	Add readDir primop	Shea Levy	1	-0/+37

2014-09-23	Add missing static	Eelco Dolstra	1	-2/+2

2014-09-22	Don't evaluate inside a "throw"	Eelco Dolstra	1	-3/+4
	Workaround for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41174. This caused hydra-eval-jobs to ignore SIGINT.
2014-09-22	Add ‘deepSeq’ primop	Eelco Dolstra	1	-0/+11
	Note that unlike ‘lib.deepSeq’ in Nixpkgs, this handles cycles.
2014-09-22	Add ‘seq’ primop	Eelco Dolstra	1	-0/+12

2014-09-22	Add a function ‘valueSize’	Eelco Dolstra	1	-0/+10
	It returns the size of value, including all other values and environments reachable from it. It is intended for debugging memory consumption issues.
2014-09-19	attrNames: Don't allocate duplicates of the symbols	Eelco Dolstra	1	-6/+4

2014-09-19	Fix off-by-one	Eelco Dolstra	1	-1/+1

2014-09-17	Add some instrumentation for debugging GC leaks	Eelco Dolstra	1	-0/+27

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	1	-40/+40

2014-07-30	Rename nixPath to __nixPath	Eelco Dolstra	1	-2/+2
	The name ‘nixPath’ breaks existing code.
2014-07-09	Fix compilation error on some versions of GCC	Eelco Dolstra	1	-0/+1
	src/libexpr/primops.cc:42:8: error: looser throw specifier for 'virtual nix::InvalidPathError::~InvalidPathError()' src/libexpr/nixexpr.hh:12:1: error: overriding 'virtual nix::EvalError::~EvalError() noexcept (true)' http://hydra.nixos.org/build/12385750
2014-07-04	Add builtin function ‘fromJSON’	Eelco Dolstra	1	-0/+10
	Fixes #294.
2014-06-24	Only add the importNative primop if the ↵	Shea Levy	1	-1/+2
	allow-arbitrary-code-during-evaluation option is true (default false)
2014-06-17	Add importNative primop	Shea Levy	1	-0/+42
	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	Drop ImportError and FindError	Eelco Dolstra	1	-4/+0
	We're not catching these anywhere.
2014-06-12	findFile: Realise the context of the path attributes	Shea Levy	1	-18/+44

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	1	-1/+1
	There really is no case I can think of where taking the context into account is useful. Mostly it's just very inconvenient.
2014-05-29	Sort nixPath attributes	Eelco Dolstra	1	-0/+1

2014-05-26	Make the Nix search path declarative	Eelco Dolstra	1	-0/+32
	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
