2017-02-22 Explicitly model all settings and fail on unrecognized onesDan Peebles10-87/+218
Previously, the Settings class allowed other code to query for string properties, which led to a proliferation of code all over the place making up new options without any sort of central registry of valid options. This commit pulls all those options back into the central Settings class and removes the public get() methods, to discourage future abuses like that. Furthermore, because we know the full set of options ahead of time, we now fail loudly if someone enters an unrecognized option, thus preventing subtle typos. With some template fun, we could probably also dump the full set of options (with documentation, defaults, etc.) to the command line, but I'm not doing that yet here.
2017-02-21 Handle CURLE_RECV_ERROR as a transient errorEelco Dolstra1-1/+1
This fixes unable to download ‘https://cache.nixos.org/nar/077h8ji74y9b0qx7rjk71xd80vjqp6q5gy137r553jlvdlxdcdlk.nar.xz’: HTTP error 200 (curl error: Failure when receiving data from the peer)

2017-02-21 Log AWS retriesEelco Dolstra1-0/+14
2017-02-16 Support netrc in <nix/fetchurl.nix>Eelco Dolstra5-7/+25
This allows <nix/fetchurl.nix> to fetch private Git/Mercurial repositories, e.g. import <nix/fetchurl.nix> { url = https://edolstra@bitbucket.org/edolstra/my-private-repo/get/80a14018daed.tar.bz2; sha256 = "1mgqzn7biqkq3hf2697b0jc4wabkqhmzq2srdymjfa6sb9zb6qs7"; } where /etc/nix/netrc contains: machine bitbucket.org login edolstra password blabla... This works even when sandboxing is enabled. To do: add unpacking support (i.e. fetchzip functionality).
2017-02-16 Move netrcFile to SettingsEelco Dolstra4-27/+23
Also get rid of Settings::processEnvironment(), it appears to be useless.
2017-02-16 Include "curl" in the User-Agent headerEelco Dolstra1-1/+1
Some sites (e.g. BitBucket) give a helpful 401 error when trying to download a private archive if the User-Agent contains "curl", but give a redirect to a login page otherwise (so for instance "nix-prefetch-url" will succeed but produce useless output).
2017-02-16 Merge pull request #1215 from k0001/netrc-1Eelco Dolstra1-0/+8
Add netrc-file support
2017-02-14 Add support for s3:// URIsEelco Dolstra5-63/+142
This adds support for s3:// URIs in all places where Nix allows URIs, e.g. in builtins.fetchurl, builtins.fetchTarball, <nix/fetchurl.nix> and NIX_PATH. It allows fetching resources from private S3 buckets, using credentials obtained from the standard places (i.e. AWS_* environment variables, ~/.aws/credentials and the EC2 metadata server). This may not be super-useful in general, but since we already depend on aws-sdk-cpp, it's a cheap feature to add.

Unbreak 32-bit builds by always implicitly including config.h
2017-02-13 nix-daemon: Don't splice with len=SIZE_MAXTuomas Tynkkynen1-2/+3
Currently, 'nix-daemon --stdio' is always failing for me, due to the splice call always failing with (on a 32-bit host): splice(0, NULL, 3, NULL, 4294967295, SPLICE_F_MOVE) = -1 EINVAL (Invalid argument) With a bit of ftracing (and luck) the problem seems to be that splice() always fails with EINVAL if the len cast as ssize_t is negative: http://lxr.free-electrons.com/source/fs/read_write.c?v=4.4#L384 So use SSIZE_MAX instead of SIZE_MAX.

2017-02-08 Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen14-24/+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.

This prevents breaking compatibility with builders that read "closure.*", since they would accidentally pick up the new JSON files.

2017-01-26 exportReferencesGraph: Export more complete info in JSON formatEelco Dolstra4-50/+90
This writes info about every path in the closure in the same format as ‘nix path-info --json’. Thus it also includes NAR hashes and sizes. Example: [ { "path": "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "narHash": "sha256:0ckdc4z20kkmpqdilx0wl6cricxv90lh85xpv2qljppcmz6vzcxl", "narSize": 197648, "references": [ "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24" ], "closureSize": 20939776 }, { "path": "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24", "narHash": "sha256:1nfn3m3p98y1c0kd0brp80dn9n5mycwgrk183j17rajya0h7gax3", "narSize": 20742128, "references": [ "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24" ], "closureSize": 20742128 } ] Fixes #1134.
2017-01-26 Add support for passing structured data to buildersEelco Dolstra4-58/+130
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.

This closes a long-time bug that allowed builds to hang Nix indefinitely (regardless of timeouts) simply by doing exec > /dev/null 2>&1; while true; do true; done Now, on EOF, we just send SIGKILL to the child to make sure it's really gone.
