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

HipChat notification messages now say which committers were
responsible, e.g.
Job patchelf:trunk:tarball: Failed, probably due to 2 commits by Eelco Dolstra
This plugin sends notification of build failure or success to a
HipChat room, if the status differs from the last build.
The plugin can be configured by adding one or more of these stanzas to
hydra.conf:
<hipchat>
jobs = (patchelf|nixops):.*:.*
room = 1234
token = 39ab2198fe...
</hipchat>
Here "jobs" is a regular expression against which the fully qualified
job name of the build is matched (so for instance
"nixops:master:tarball" will match the stanza above).
Restarted builds whose derivation has been garbage-collected in the
meantime caused hydra-queue-runner to get stuck in a loop saying:
Jun 14 11:54:25 lucifer hydra-queue-runner[31844]: system type `x86_64-darwin': 0 active, 2 allowed, started 2 builds
Jun 14 11:54:25 lucifer hydra-queue-runner[31844]: {UNKNOWN}: path `/nix/store/wcizsch2garjlvs4pswrar47i1hwjaia-inconsolata.drv' is not valid at
/nix/store/ypkdm4v13yrk941rvp8h0y425a5ww6nm-hydra-0.1pre1353-40debf1/bin/.hydra-queue-runner-wrapped line 51. at
/nix/store/kjpsc2zdaxnd44azxyw60f2px839m1cd-hydra-perl-deps/lib/perl5/site_perl/5.16.2/Catalyst/Model/DBIC/Schema.pm line 501
This happens if the previous iteration took more than 60 seconds.
Then the queue runner may think that builds failed to start properly
and unlock them, e.g.
build 5264936 pid 19248 died, unlocking
build 5264951 pid 19248 died, unlocking
build 5257073 pid 19248 died, unlocking
...
Because we don't start a build if a dependency is already building,
it's possible that some or all of the $extraAllowed highest-priority
builds in the queue are not eligible. E.g. with $extraAllowed = 32,
we might start only 3 builds even though there are thousands in the
queue. The fix is to try all queued builds until $extraAllowed have
been started.
Issue #99.
Config::Any uses Module::Pluggable to seach for plugins, so it needs
the patched Module::Pluggable in Nixpkgs (rather than the one in Perl
itself) to properly find plugins in symlink trees created by buildEnv.
For some reason, hg clone from a local (path-based) repo will fail if
the parent directory of the destination directory doesn't exist (though
it succeeds when cloning from an http repo).
