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.

2017-01-07 nix-shell: Fix 'nix-shell --command' doing nothing without TTYTuomas Tynkkynen1-1/+2
Regression from a5f2750e ("Fix early removal of rc-file for nix-shell"). The removal of BASH_ENV causes nothing to be executed by bash if it detects itself in a non-interactive context. Instead, just use the same condition used by bash to launch bash differently. According to bash sources, the condition (stdin and stder both must be TTYs) is specified by POSIX so this should be pretty safe to rely on. Fixes #1171 on master, needs a backport to the Perl code in 1.11.

2017-01-03 nix-shell: Don't act interactive in shebangsTuomas Tynkkynen1-0/+1
I had observed that 'bash --rcfile' would do nothing in a non-interactive context and cause nothing to be executed if a script using nix-shell shebangs were run in a non-interactive context.
2017-01-03 nix-shell: Fix 'nix-shell -i'Tuomas Tynkkynen1-1/+1
The 'args' variable here is shadowing one in the outer scope and its contents end up unused. This causes any '#! nix-shell' lines to effectively be ignored. The intention here was to clear the args vector, as far as I can tell (and it seems to work).

2016-12-08 Fix S3BinaryCacheStoreEelco Dolstra4-53/+11
It failed with AWS error uploading ‘6gaxphsyhg66mz0a00qghf9nqf7majs2.ls.xz’: Unable to parse ExceptionName: MissingContentLength Message: You must provide the Content-Length HTTP header. possibly because the istringstream_nocopy introduced in 0d2ebb4373e509521f27a6e8f16bfd39d05b2188 doesn't supply the seek method that the AWS library expects. So bring back the old version, but only for S3BinaryCacheStore.
