2019-07-30	Allow builtins.pathExists to check the existence of /nix/store paths	Bas van Dijk	1	-2/+8
	This makes it consitent with builtins.readDir.
2019-06-24	Refactor downloadCached() interface	Eelco Dolstra	1	-11/+11
	(cherry picked from commit df3f5a78d5ab0a1f2dc9d288b271b38a9b8b33b5)
2019-06-24	downloadCached: Return ETag	Eelco Dolstra	1	-1/+1
	(cherry picked from commit 529add316c5356a8060c35f987643b7bf5c796dc)
2019-05-03	Add builtins.hashFile	Daniel Schaefer	1	-0/+15
	For text files it is possible to do it like so: `builtins.hashString "sha256" (builtins.readFile /tmp/a)` but that doesn't work for binary files. With builtins.hashFile any kind of file can be conveniently hashed.
2019-03-24	Add isPath primop	zimbatm	1	-0/+7
	this is added for completeness' sake since all the other possible `builtins.typeOf` results have a corresponding `builtins.is<Type>`
2019-03-14	experimental/optional -> optional	Eelco Dolstra	1	-1/+1

2019-01-14	Add builtins.getContext.	Shea Levy	1	-38/+0
	This can be very helpful when debugging, as well as enabling complex black magic like surgically removing a single dependency from a string's context.
2019-01-13	Treat plain derivation paths in context as normal paths.	Shea Levy	1	-17/+3
	Previously, plain derivation paths in the string context (e.g. those that arose from builtins.storePath on a drv file, not those that arose from accessing .drvPath of a derivation) were treated somewhat like derivaiton paths derived from .drvPath, except their dependencies weren't recursively added to the input set. With this change, such plain derivation paths are simply treated as paths and added to the source inputs set accordingly, simplifying context handling code and removing the inconsistency. If drvPath-like behavior is desired, the .drv file can be imported and then .drvPath can be accessed. This is a backwards-incompatibility, but storePath is never used on drv files within nixpkgs and almost never used elsewhere.
2018-12-13	Support SRI hashes	Eelco Dolstra	1	-6/+4
	SRI hashes (https://www.w3.org/TR/SRI/) combine the hash algorithm and a base-64 hash. This allows more concise and standard hash specifications. For example, instead of import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; sha256 = "5d22dad058d5c800d65a115f919da22938c50dd6ba98c5e3a183172d149840a4"; }; you can write import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; hash = "sha256-XSLa0FjVyADWWhFfkZ2iKTjFDda6mMXjoYMXLRSYQKQ="; }; In fixed-output derivations, the outputHashAlgo is no longer mandatory if outputHash specifies the hash (either as an SRI or in the old "<type>:<hash>" format). 'nix hash-{file,path}' now print hashes in SRI format by default. I also reverted them to use SHA-256 by default because that's what we're using most of the time in Nixpkgs. Suggested by @zimbatm.

2018-07-21	prim_foldlStrict: call forceValue() before value is copied	volth	1	-6/+7
	forceValue() were called after a value is copied effectively forcing only one of the copies keeping another copy not evaluated. This resulted in its evaluation of the same lazy value more than once (the number of hits is not big though)

	stored in mkApp

2018-02-26	libexpr: Fix prim_replaceStrings() to work on an empty source string	Tuomas Tynkkynen	1	-3/+14
	Otherwise, running e.g. nix-instantiate --eval -E --strict 'builtins.replaceStrings [""] ["X"] "abc"' would just hang in an infinite loop. Found by afl-fuzz. First attempt of this was reverted in e2d71bd1862cdda because it caused another infinite loop, which is fixed now and a test added.
2018-02-21	Revert "libexpr: Fix prim_replaceStrings() to work on an empty source string"	Eelco Dolstra	1	-8/+3
	This reverts commit 4ea9707591beceacf9988b3c185faf50da238403. It causes an infinite loop in Nixpkgs evaluation, e.g. "nix-instantiate -A hello" hung. PR #1886.
2018-02-19	libexpr: Fix prim_replaceStrings() to work on an empty source string	Tuomas Tynkkynen	1	-3/+8

2018-02-17	libexpr: Avoid an unnecessary string copy in prim_derivationStrict	Tuomas Tynkkynen	1	-1/+1

2018-02-17	libexpr: Remove unnecessary drvName assignment in prim_derivationStrict	Tuomas Tynkkynen	1	-6/+0
	drvName is already assigned to the same value right at the start of the function.
2018-02-17	libexpr: Optimize prim_derivationStrict by using more symbol comparisons	Tuomas Tynkkynen	1	-9/+9

2018-02-17	libexpr: Optimize prim_attrNames a bit	Tuomas Tynkkynen	1	-2/+5
	Instead of having lexicographicOrder() create a temporary sorted array of Attr*:s and copying attr names from that, copy the attr names first and then sort that.
2018-02-14	Add splitVersion primop.	Shea Levy	1	-0/+21
	Fixes #1868.
2018-02-07	Merge pull request #1816 from shlevy/add-path	Eelco Dolstra	1	-18/+75
	Add path primop.
2018-02-06	Add path primop.	Shea Levy	1	-18/+75
	builtins.path allows specifying the name of a path (which makes paths with store-illegal names now addable), allows adding paths with flat instead of recursive hashes, allows specifying a filter (so is a generalization of filterSource), and allows specifying an expected hash (enabling safe path adding in pure mode).
2018-02-06	realiseContext(): Add derivation outputs to the allowed paths	Eelco Dolstra	1	-10/+24
	This makes import-from-derivation work in restricted mode again.
2018-01-18	Don't define builtins.{currentSystem,currentTime} in pure mode	Eelco Dolstra	1	-6/+2
	This makes it easier to provide a default, e.g. system = builtins.currentSystem or "x86_64-linux";
2018-01-17	Typo	Eelco Dolstra	1	-1/+1

2018-01-16	Add pure evaluation mode	Eelco Dolstra	1	-9/+35
	In this mode, the following restrictions apply: * The builtins currentTime, currentSystem and storePath throw an error. * $NIX_PATH and -I are ignored. * fetchGit and fetchMercurial require a revision hash. * fetchurl and fetchTarball require a sha256 attribute. * No file system access is allowed outside of the paths returned by fetch{Git,Mercurial,url,Tarball}. Thus 'nix build -f ./foo.nix' is not allowed. Thus, the evaluation result is completely reproducible from the command line arguments. E.g. nix build --pure-eval '( let nix = fetchGit { url = https://github.com/NixOS/nixpkgs.git; rev = "9c927de4b179a6dd210dd88d34bda8af4b575680"; }; nixpkgs = fetchGit { url = https://github.com/NixOS/nixpkgs.git; ref = "release-17.09"; rev = "66b4de79e3841530e6d9c6baf98702aa1f7124e4"; }; in (import (nix + "/release.nix") { inherit nix nixpkgs; }).build.x86_64-linux )' The goal is to enable completely reproducible and traceable evaluation. For example, a NixOS configuration could be fully described by a single Git commit hash. 'nixos-rebuild' would do something like nix build --pure-eval '( (import (fetchGit { url = file:///my-nixos-config; rev = "..."; })).system ') where the Git repository /my-nixos-config would use further fetchGit calls or Git externals to fetch Nixpkgs and whatever other dependencies it has. Either way, the commit hash would uniquely identify the NixOS configuration and allow it to reproduced.

2017-10-30	fetchTarball: Use "source" as the default name	Eelco Dolstra	1	-4/+4
	This ensures that it produces the same output as fetchgit: $ nix eval --raw '(builtins.fetchgit https://github.com/NixOS/patchelf.git)' /nix/store/ghigrkw02l440g8vfxa9wj4c3zpfmw99-source $ nix eval --raw '(fetchTarball https://github.com/NixOS/patchelf/archive/master.tar.gz)' /nix/store/ghigrkw02l440g8vfxa9wj4c3zpfmw99-source
2017-10-30	fetchurl/fetchTarball: Respect name changes	Eelco Dolstra	1	-1/+1
	The computation of urlHash didn't take the name into account, so subsequent fetchurl calls with the same URL but a different name would resolve to the same cached store path.
