Kill builds when we get EOF on the log FD 
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.

Handle SIGINT etc. via a sigwait() signal handler thread 
This allows other threads to install callbacks that run in a regular,
non-signal context. In particular, we can use this to signal the
downloader thread to quit.

Closes #1183.

Tuomas Tynkkynen 3890de049d nix-shell: Fix 'nix-shell --command' doing nothing without TTY 
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.

Tuomas Tynkkynen 018f884ffd nix-shell: Don't act interactive in shebangs 
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.

Tuomas Tynkkynen c698ec1f22 nix-shell: Fix 'nix-shell -i' 
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).

S3BinaryCacheStore: Ensure it only builds on Linux 2016-12-08 15:35:46 +01:00
Eelco Dolstra e6a61b8da7
Fix S3BinaryCacheStore 
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
0d2ebb4373 doesn't supply the seek
method that the AWS library expects. So bring back the old version,
but only for S3BinaryCacheStore.

That is, when build-repeat > 0, and the output of two rounds differ,
then print a warning rather than fail the build. This is primarily to
let Hydra check reproducibility of all packages.
