2018-02-19 libexpr: Don't create lots of temporary strings in Bindings::lexicographicOrderTuomas Tynkkynen1-1/+1
Avoids ~180,000 string temporaries created when evaluating a headless NixOS system.
2018-02-17 libexpr: Avoid an unnecessary string copy in prim_derivationStrictTuomas Tynkkynen1-1/+1
2018-02-17 libexpr: Remove unnecessary drvName assignment in prim_derivationStrictTuomas Tynkkynen1-6/+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 comparisonsTuomas Tynkkynen3-10/+15
2018-02-17 libexpr: Rely on Boehm returning zeroed memory in EvalState::allocEnv()Tuomas Tynkkynen2-5/+5
Boehm guarantees that memory returned by GC_malloc() is zeroed, so take advantage of that.
2018-02-17 libexpr: Optimize prim_attrNames a bitTuomas Tynkkynen1-2/+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.
2018-02-16 libexpr: Pre-reserve space in string in unescapeStr()Tuomas Tynkkynen1-3/+4
Avoids some malloc() traffic.
2018-02-14 Add splitVersion primop.Shea Levy3-1/+24
Fixes #1868.
2018-02-13 Merge branch 'register-constant' of https://github.com/shlevy/nixEelco Dolstra3-2/+11
2018-02-11 Nix stats: flatten statisticsFrederik Rietdijk1-3/+6
Flattens the list of statistics as suggested in https://github.com/NixOS/ofborg/issues/67. This makes it easier to work with.
2018-02-08 Allow using RegisterPrimop to define constants.Shea Levy3-2/+11
This enables plugins to add new constants, as well as new primops.
2018-02-07 Merge pull request #1816 from shlevy/add-pathEelco Dolstra2-19/+76
Add path primop.
2018-02-06 Add path primop.Shea Levy2-19/+76
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 pathsEelco Dolstra1-10/+24
This makes import-from-derivation work in restricted mode again.
2018-02-06 checkURI(): Check file URIs against allowedPathsEelco Dolstra1-0/+12
This makes e.g. 'fetchGit ./.' work (assuming that ./. is an allowed path).
2018-01-19 Don't use [[noreturn]]Eelco Dolstra1-6/+3
2018-01-18 Don't define builtins.{currentSystem,currentTime} in pure modeEelco Dolstra1-6/+2
This makes it easier to provide a default, e.g. system = builtins.currentSystem or "x86_64-linux";
2018-01-17 TypoEelco Dolstra1-1/+1
2018-01-16 Add pure evaluation modeEelco Dolstra5-44/+94
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.
2018-01-12 import, builtins.readFile: Handle diverted storesEelco Dolstra3-6/+25
Fixes #1791
2018-01-09 fetchGit: fix creation of uninitialized cache dir, let git create itWill Dietz1-1/+0
fetchGit test (as modified in previous commit) now passes.
2018-01-02 Add hasContext primopShea Levy1-0/+9
2017-12-22 fetchGit: Fix handling of local repo when not using 'master' branchWill Dietz1-1/+5
Add tests checking this behavior.
2017-12-14 json-to-value: Throw sensible error message on invalid numbersBen Gamari1-4/+10
2017-12-05 Merge branch 'fetchGit-fast-revision-update'Shea Levy1-24/+35
2017-11-24 nix-shell/nix-build: Support .drv files againEelco Dolstra2-0/+29
Fixes #1663. Also handle '!<output-name>' (#1694).
2017-11-24 fetchGit: Ignore tarballTtl if rev is set and not in the repo.Shea Levy1-24/+35
Fixes #1697.
2017-11-21 fetchGit/fetchMercurial: Fix directory inclusion checkEelco Dolstra2-4/+6
E.g. the existence of .gitignore would cause .git to be included.
2017-11-14 Revert "Don't parse "x:x" as a URI"Eelco Dolstra1-1/+1
This reverts commit f90f660b243866b8860eeb24cc4a345d32cc7ce7. This broke Hydra's release.nix, which contained preCheck = ''export LOGNAME=${LOGNAME:-foo}'';
2017-11-03 fetchgit.cc -> fetchGit.ccEelco Dolstra1-0/+0
2017-11-03 Remove git:// support in NIX_PATHEelco Dolstra3-31/+9
This didn't support specifying a revision/branch, and was restricted to git:// URIs (since https:// or ssh:// would be ambiguous).
2017-11-03 fetchGit/fetchMercurial: Filter out directories with untracked filesEelco Dolstra2-8/+16
2017-11-03 fetchGit: Add a testEelco Dolstra1-1/+1
2017-11-03 fetchGit: Don't do a remote fetch if we already have the revEelco Dolstra1-15/+23
2017-11-02 fetchMercurial: fix error messagetv1-1/+1
2017-11-01 Fix buildEelco Dolstra2-2/+2
https://hydra.nixos.org/build/63172338
2017-11-01 fetchMercurial: Don't fetch hashes we already haveEelco Dolstra1-9/+19
2017-11-01 Add fetchMercurial primopEelco Dolstra2-2/+189
E.g. $ nix eval '(fetchMercurial https://www.mercurial-scm.org/repo/hello)' { branch = "default"; outPath = "/nix/store/alvb9y1kfz42bjishqmyy3pphnrh1pfa-source"; rev = "82e55d328c8ca4ee16520036c0aaace03a5beb65"; revCount = 1; shortRev = "82e55d328c8c"; } $ nix eval '(fetchMercurial { url = https://www.mercurial-scm.org/repo/hello; rev = "0a04b987be5ae354b710cefeba0e2d9de7ad41a9"; })' { branch = "default"; outPath = "/nix/store/alvb9y1kfz42bjishqmyy3pphnrh1pfa-source"; rev = "0a04b987be5ae354b710cefeba0e2d9de7ad41a9"; revCount = 0; shortRev = "0a04b987be5a"; } $ nix eval '(fetchMercurial /tmp/unclean-hg-tree)' { branch = "default"; outPath = "/nix/store/cm750cdw1x8wfpm3jq7mz09r30l9r024-source"; rev = "0000000000000000000000000000000000000000"; revCount = 0; shortRev = "000000000000"; }
2017-10-31 Fix filterSourceEelco Dolstra1-32/+14
2017-10-30 builtins.fetchgit: Support importing a working treeEelco Dolstra3-7/+47
For example, you can write src = fetchgit ./.; and if ./. refers to an unclean working tree, that tree will be copied to the Nix store. This removes the need for "cleanSource".
2017-10-30 Don't parse "x:x" as a URIEelco Dolstra1-1/+1
URIs now have to contain "://" or start with "channel:".
2017-10-30 Make "fetchGit /path" workEelco Dolstra1-5/+5
2017-10-30 fetchGit: Fix broken assertionEelco Dolstra1-1/+1
Different URIs can map to the same cache entry if they have the same revision.
2017-10-30 Add option allowed-urisEelco Dolstra4-5/+27
This allows network access in restricted eval mode.
2017-10-30 builtins.fetchGit: Return an attrset with revision infoEelco Dolstra3-18/+54
This adds rev, shortRev and revCount attributes, equal to what Hydra provides. E.g. $ nix eval '(fetchGit https://github.com/NixOS/patchelf.git)' { outPath = "/nix/store/ghigrkw02l440g8vfxa9wj4c3zpfmw99-source"; rev = "29c085fd9d3fc972f75b3961905d6b4ecce7eb2b"; revCount = 303; shortRev = "29c085f"; }
2017-10-30 enable-http2 -> http2Eelco Dolstra1-1/+1
2017-10-30 fetchgit -> fetchGitEelco Dolstra1-4/+4
Almost all other primops are camelCase so no reason not to use that here.
2017-10-30 fetchTarball: Use "source" as the default nameEelco Dolstra1-4/+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 changesEelco Dolstra1-1/+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.
2017-10-30 builtins.fetchgit: Don't mess up the progress indicatorEelco Dolstra1-3/+5
