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
10882a1ffdbc9c6050c0528cf95be98fb5541d50 ("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'.
Chaining paths only works properly when PathPart is used. Before this
fix, the affected URIs bypassed the top-level 'admin' sub.

This reverts commit 71d020735bb6f8e2f46a7813fe73d2a8dbe37add.
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.
You can use the URL
http://<hydra-server>/api/push-github
as GitHub's WebHook URL. Hydra will automatically trigger an
evaluation of all affected jobsets.
We once turned these off (in commit
abe71a767b266a157836c0fd45330ec415720bef) because they caused the
PostgreSQL query optimizer to use very suboptimal plans. However,
PostgreSQL 9.2 has supposedly fixed this:
http://www.postgresql.org/docs/9.2/static/release-9-2.html
So let's try again.
