2017-02-08 Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen3-4/+0
Because config.h can #define things like _FILE_OFFSET_BITS=64 and not every compilation unit includes config.h, we currently compile half of Nix with _FILE_OFFSET_BITS=64 and other half with _FILE_OFFSET_BITS unset. This causes major havoc with the Settings class on e.g. 32-bit ARM, where different compilation units disagree with the struct layout. E.g.: diff --git a/src/libstore/globals.cc b/src/libstore/globals.cc @@ -166,6 +166,8 @@ void Settings::update() _get(useSubstitutes, "build-use-substitutes"); + fprintf(stderr, "at Settings::update(): &useSubstitutes = %p\n", &nix::settings.useSubstitutes); _get(buildUsersGroup, "build-users-group"); diff --git a/src/libstore/remote-store.cc b/src/libstore/remote-store.cc +++ b/src/libstore/remote-store.cc @@ -138,6 +138,8 @@ void RemoteStore::initConnection(Connection & conn) void RemoteStore::setOptions(Connection & conn) { + fprintf(stderr, "at RemoteStore::setOptions(): &useSubstitutes = %p\n", &nix::settings.useSubstitutes); conn.to << wopSetOptions Gave me: at Settings::update(): &useSubstitutes = 0xb6e5c5cb at RemoteStore::setOptions(): &useSubstitutes = 0xb6e5c5c7 That was not a fun one to debug!
2017-01-26 Add support for passing structured data to buildersEelco Dolstra3-40/+91
Previously, all derivation attributes had to be coerced into strings so that they could be passed via the environment. This is lossy (e.g. lists get flattened, necessitating configureFlags vs. configureFlagsArray, of which the latter cannot be specified as an attribute), doesn't support attribute sets at all, and has size limitations (necessitating hacks like passAsFile). This patch adds a new mode for passing attributes to builders, namely encoded as a JSON file ".attrs.json" in the current directory of the builder. This mode is activated via the special attribute __structuredAttrs = true; (The idea is that one day we can set this in stdenv.mkDerivation.) For example, stdenv.mkDerivation { __structuredAttrs = true; name = "foo"; buildInputs = [ pkgs.hello pkgs.cowsay ]; doCheck = true; hardening.format = false; } results in a ".attrs.json" file containing (sans the indentation): { "buildInputs": [], "builder": "/nix/store/ygl61ycpr2vjqrx775l1r2mw1g2rb754-bash-4.3-p48/bin/bash", "configureFlags": [ "--with-foo", "--with-bar=1 2" ], "doCheck": true, "hardening": { "format": false }, "name": "foo", "nativeBuildInputs": [ "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "/nix/store/4jnvjin0r6wp6cv1hdm5jbkx3vinlcvk-cowsay-3.03" ], "propagatedBuildInputs": [], "propagatedNativeBuildInputs": [], "stdenv": "/nix/store/f3hw3p8armnzy6xhd4h8s7anfjrs15n2-stdenv", "system": "x86_64-linux" } "passAsFile" is ignored in this mode because it's not needed - large strings are included directly in the JSON representation. It is up to the builder to do something with the JSON representation. For example, in bash-based builders, lists/attrsets of string values could be mapped to bash (associative) arrays.

2016-10-26 Fix SIGFPE from integer overflow during divisionTuomas Tynkkynen1-3/+9
On some architectures (like x86_64 or i686, but not ARM for example) overflow during integer division causes a crash due to SIGFPE. Reproduces on a 64-bit system with: nix-instantiate --eval -E '(-9223372036854775807 - 1) / -1' The only way this can happen is when the smallest possible integer is divided by -1, so just special-case that.

2016-09-14 Enable HTTP/2 supportEelco Dolstra3-3/+3
The binary cache store can now use HTTP/2 to do lookups. This is much more efficient than HTTP/1.1 due to multiplexing: we can issue many requests in parallel over a single TCP connection. Thus it's no longer necessary to use a bunch of concurrent TCP connections (25 by default). For example, downloading 802 .narinfo files from https://cache.nixos.org/, using a single TCP connection, takes 11.8s with HTTP/1.1, but only 0.61s with HTTP/2. This did require a fairly substantial rewrite of the Downloader class to use the curl multi interface, because otherwise curl wouldn't be able to do multiplexing for us. As a bonus, we get connection reuse even with HTTP/1.1. All downloads are now handled by a single worker thread. Clients call Downloader::enqueueDownload() to tell the worker thread to start the download, getting a std::future to the result.

2016-08-29 Add builtin function "partition"Eelco Dolstra5-10/+48
The implementation of "partition" in Nixpkgs is O(n^2) (because of the use of ++), and for some reason was causing stack overflows in multi-threaded evaluation (not sure why). This reduces "nix-env -qa --drv-path" runtime by 0.197s and memory usage by 298 MiB (in non-Boehm mode).
2016-08-29 nix path-info: Add --json flagEelco Dolstra3-99/+30
Also, factor out JSON generation from value-to-json.{cc,hh}, and support producing indented JSON.
2016-08-29 callFunction: Copy functors to the heapShea Levy1-4/+11
Normally it's impossible to take a reference to the function passed to callFunction, so some callers (e.g. ExprApp::eval) allocate that value on the stack. For functors, a reference to the functor itself may be kept, so we need to have it on the heap. Fixes #1045
2016-08-23 nix build: Use Nix search pathEelco Dolstra2-5/+8
That is, unless --file is specified, the Nix search path is synthesized into an attribute set. Thus you can say $ nix build nixpkgs.hello assuming $NIX_PATH contains an entry of the form "nixpkgs=...". This is more verbose than $ nix build hello but is less ambiguous.
2016-08-17 Add a mechanism for derivation attributes to reference the derivation's outputsEelco Dolstra1-0/+14
For example, you can now say: configureFlags = "--prefix=${placeholder "out"} --includedir=${placeholder "dev"}"; The strings returned by the ‘placeholder’ builtin are replaced at build time by the actual store paths corresponding to the specified outputs. Previously, you had to work around the inability to self-reference by doing stuff like: preConfigure = '' configureFlags+=" --prefix $out --includedir=$dev" ''; or rely on ad-hoc variable interpolation semantics in Autoconf or Make (e.g. --prefix=\$(out)), which doesn't always work.

E.g. $ nix-build -I nixpkgs=git://github.com/NixOS/nixpkgs '<nixpkgs>' -A hello This is not extremely useful yet because you can't specify a branch/revision.
2016-04-29 Add fetchgit builtinEelco Dolstra1-0/+77
The function builtins.fetchgit fetches Git repositories at evaluation time, similar to builtins.fetchTarball. (Perhaps the name should be changed, being confusing with respect to Nixpkgs's fetchgit function, with works at build time.) Example: (import (builtins.fetchgit git://github.com/NixOS/nixpkgs) {}).hello or (import (builtins.fetchgit { url = git://github.com/NixOS/nixpkgs-channels; rev = "nixos-16.03"; }) {}).hello Note that the result does not contain a .git directory.
2016-04-25 Improved logging abstractionEelco Dolstra3-8/+7
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.

2016-04-14 Make the search path lazier with non-fatal errorsEelco Dolstra4-34/+69
Thus, -I / $NIX_PATH entries are now downloaded only when they are needed for evaluation. An error to download an entry is a non-fatal warning (just like non-existant paths). This does change the semantics of builtins.nixPath, which now returns the original, rather than resulting path. E.g., before we had [ { path = "/nix/store/hgm3yxf1lrrwa3z14zpqaj5p9vs0qklk-nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] but now [ { path = "https://nixos.org/channels/nixos-16.03/nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] Fixes #792.

2016-02-04 Eliminate the "store" global variableEelco Dolstra6-36/+40
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
