will cause Hydra to perform every build step in the specified jobset 2
additional times (i.e. 3 times in total). Non-determinism is not fatal
unless the derivation has the attribute "isDeterministic = true"; we
just note the lack of determinism in the Hydra database. This will
allow us to get stats about the (lack of) reproducibility of all of
Nixpkgs.
The catalyst-action-rest branch from shlevy/hydra was an exploration of
using Catalyst::Action::REST to create a JSON API for hydra. This commit
merges in the best bits from that experiment, with the goal that further
API endpoints can be added incrementally.
In addition to migrating more endpoints, there is potential for
improvement in what's already been done:
* The web interface can be updated to use the same non-GET endpoints as
the JSON interface (using x-tunneled-method) instead of having a
separate endpoint
* The web rendering should use the $c->stash->{resource} data structure
where applicable rather than putting the same data in two places in
the stash
* Which columns to render for each endpoint is a completely debatable
question
* Hydra::Component::ToJSON should turn has_many relations that have
strings as their primary keys into objects instead of arrays

It's pointless to store these, since Nix knows where the logs are.
Also handle (in fact require) Nix's new log storage scheme. Also some
cleanups in the build page.
The singleton table SchemaVersion contains the current version
of the Hydra database schema. This can be used to upgrade the
schema on the fly.
Also reran the DBIx::Class schema loader.
* Store the system type in the BuildSteps table.
* Don't query the queue size when serving static pages. This prevents
two unnecessary database queries per request.
releases as a dynamic view on the database was misguided, since
doing thing like adding a new job to a release set will invalidate
all old releases. So we rename release sets to views, and we'll
reintroduce releases as separate, static entities in the database.
the derivations that the jobset currently contains. This is
necessary to allow the "latest" channel to contain the correct
builds when the sources of a jobset are reverted.
distinguish between jobs with the same name in different jobsets
(e.g. "trunk" vs "stdenv-branch" for Nixpkgs).
* Renamed the "attrName" field of Builds to "job".
* Renamed the "id" field of BuildSteps to "build".
Note: to upgrade old databases, do a dump with an old Sqlite first;
dumping with a new Sqlite will silently discard (!) the contents of
the ReleaseSetJobs table.
failed in a previous build. This is essential for Nixpkgs: we don't
want to keep doing the same failed dependency (say, Glibc) over and
over again for a few hundred jobs.
