2017-03-03 Improve SSH handlingEelco Dolstra6-112/+179
* Unify SSH code in SSHStore and LegacySSHStore. * Fix a race starting the SSH master. We now wait synchronously for the SSH master to finish starting. This prevents the SSH clients from starting their own connections. * Don't use a master if max-connections == 1. * Add a "max-connections" store parameter. * Add a "compress" store parameter.
2017-03-03 Fix fatal "broken pipe" error when $NIX_BUILD_HOOK is missingEelco Dolstra1-27/+39
2017-03-01 TeeSink: Pre-reserve string spaceEelco Dolstra1-6/+5
When receiving a very large file, this can prevent the string from having tobe copied, which temporarily doubles memory consumption.
2017-03-01 RemoteStore::addToStore(): Send NAR rather than string containing NAREelco Dolstra3-26/+6
This allows the NAR to be streamed in the future (though we're not doing that yet).
2017-03-01 Tweak messageEelco Dolstra1-1/+1
2017-03-01 Handle importing NARs containing files greater than 4 GiBEelco Dolstra3-18/+16
Also templatize readInt() to work for various integer types.

2017-02-28 NarInfoDiskCache: Handle SQLite busy errorsEelco Dolstra1-104/+115
2017-02-28 In SQLite errors, include the database pathEelco Dolstra1-4/+8
This is necessary because we have multiple SQLite databases (e.g. the binary cache cache).
2017-02-28 Support auto-configuration of build-max-jobsEelco Dolstra1-1/+8
"build-max-jobs" and the "-j" option can now be set to "auto" to use the number of CPUs in the system. (Unlike build-cores, it doesn't use 0 to imply auto-configuration, because a) magic values are a bad idea in general; b) 0 is a legitimate value used to disable local building.) Fixes #1198.

2017-02-22 RemoteStore::addToStore(): Pass content-addressability assertionEelco Dolstra5-3/+15
... and use this in Downloader::downloadCached(). This fixes $ nix-build https://nixos.org/channels/nixos-16.09-small/nixexprs.tar.xz -A hello error: cannot import path ‘/nix/store/csfbp1s60dkgmk9f8g0zk0mwb7hzgabd-nixexprs.tar.xz’ because it lacks a valid signature
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 Dolstra3-4/+22
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 Dolstra3-26/+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 Dolstra4-63/+141
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.

2017-02-08 Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen5-9/+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 is useful for nix-copy-closure.

For example, SSH stores could be trusted.

2017-02-02 exportReferencesGraph: Only export in JSON format when in structured modeEelco Dolstra1-10/+16
This prevents breaking compatibility with builders that read "closure.*", since they would accidentally pick up the new JSON files.
2017-02-01 Restore default signal handling in child processesEelco Dolstra2-2/+3
In particular, this fixes Ctrl-C in nix-shell sessions.

2017-01-26 exportReferencesGraph: Export more complete info in JSON formatEelco Dolstra3-1/+84
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 Dolstra1-18/+39
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.

startBuilder() is getting rather obese.
