You can now do:
bash <(curl http://hydra-server/build/1238757/reproduce)
to download and execute a script that reproduces a Hydra build
locally. This script fetches all inputs (e.g. Git repositories) and
then invokes nix-build.
The downloaded sources are stored in /tmp/build-<buildid> and reused
between invocations of the script.
Any additional command line options are passed to nix-build. So
bash <(curl http://hydra-server/build/1238757/reproduce) --run-env
will drop you in a shell where you can interactively hack on the
build, e.g.
$ source $stdenv/setup
$ set +e
$ unpackPhase
$ cd $sourceRoot
$ configurePhase
$ emacs foo.c &
$ make
and so on.
Build product paths cannot reference locations outside of the Nix
store. We previously disallowed paths from being symlinks, but this
didn't take into account that parent path elements can be symlinks as
well. So a build product /nix/store/bla.../foo/passwd, with
/nix/store/bla.../foo being a symlink to /etc, would still work.
So now we check all paths encountered during path resolution.
Symlinks are allowed again so long as they point to the Nix store.
This is a followup to commit
10882a1ffd ("Add multiple output
support").
* src/script/hydra-eval-guile-jobs.in (job-evaluations->sxml): Return
several `output' tags in the body, and remove the `outPath' attribute
of `job'.
Remove some unnecessary configurability, remove all hydra.nixos.org
assumptions, remove some policy (e.g. nix.gc.automatic) that are
orthogonal to hydra.

Chaining paths only works properly when PathPart is used. Before this
fix, the affected URIs bypassed the top-level 'admin' sub.

This reverts commit 71d020735b.
Unfortunately there are still some cases where we need to set Hydra's
concurrency separately. (Ideally, Hydra would start *all* queued
builds in parallel and let Nix take care of everything...)
So now "?compare=<jobset name>" is no longer a hidden feature!
P.S. Encountered this wonderful TemplateToolkit brainfuck again: if
you want to get the number of rows in (say) project.jobsets, you can't
say "project.jobsets.size". That will *usually* give the right
result, except that if there is only one row in project.jobsets, it
will evaluate to 3. Instead you have to use "project.jobsets_rs.count".
Note that on machines that support multiple system types, EACH system type gets the full number of build slots, which is almost certainly not what we want.
