Builds can now emit metrics that Hydra will store in its database and
render as time series via flot charts. Typical applications are to
keep track of performance indicators, coverage percentages, artifact
sizes, and so on.
For example, a coverage build can emit the coverage percentage as
follows:
echo "lineCoverage $pct %" > $out/nix-support/hydra-metrics
Graphs of all metrics for a job can be seen at
http://.../job/<project>/<jobset>/<job>#tabs-charts
Specific metrics are also visible at
http://.../job/<project>/<jobset>/<job>/metric/<metric>
The latter URL also allows getting the data in JSON format (e.g. via
"curl -H 'Accept: application/json'").
If Hydra isn't hosted on https://example.com/ but something like
https://example.com/hydra/, the URL for /api/scmdiff would have ended up
on /api/scmdiff rather than /hydra/api/scmdiff.
This is because we didn't use the URI resolver from the controller,
hence we're using it now to build up the whole URL including the query
string.

Without an index on (machine, stoptime desc), this requires a
sequential scan. And adding a whole index for this seems
overkill. (Possibly the queue runner could maintain this info more
efficiently.)
Aborted builds are now put back on the runnable queue and retried
after a certain time interval (currently 60 seconds for the first
retry, then tripled on each subsequent retry).
When visiting the tail-reload page, for a short amount of time the
"unscrolled" version is shown. To circumvent that, let's scroll down
immediately at the first possibility to fill the gap between the loading
of the document and the first AJAX request coming in.

There are quite a lot of build outputs which have lines with a length
exceeding the width of the taillog <pre/> and thus visually produce more
lines than 50. This causes the tail "box" to change height frequently
and to get to the bottom you need to scroll down.
We now set a fixed line-height to 120% of the font size and cap the
maximum height based on that value (50 * 1.2 = 60). It's probably not
nice to override the line-height, but max-lines is currently only
available using browser-specific property names. But after all it's just
for the tail output, if people complain about the line-height, we can
still change it :-)

We're just implicitly escaping the tail content by not using .load() but
explicitly setting the text content using .text(), so that escaping
isn't needed on our side.
This should get rid of a few formatting errors and possibly XSS if
someone manages to place JS code in the tail of a build and manages to
lurk a user to that tail output.

Like eval IDs, build IDs don't convey useful information.
Also, make the job name link to the build rather than the job. When
people click on a build, they expect to go to the build page, not the
job page.
Scheduling is mostly based on jobset shares these days. So showing and
sorting by priority just wastes space and gives the incorrect
impression that Hydra executes builds in the order shown on the queue
page.
In the dashboard and on the job page, indicate whether the job appears
in the latest jobset eval. That way, the user gets some indication if
a job has accidentally disappeared (e.g. due to an evaluation error).
Use the following in your hydra.conf to make your instance a
private Hydra instance (public is the default):
private 1
Currently, this will not allow you to use the API, channels
and the binary cache when running in private mode. We will add
solutions for these functionalities later.
For users who only have the "create-projects" role, actually display the
item in the menu as the only option.

Include information about who changed the build status in notification
emails, and enable optional per-input notification of said committers.

Currently the dashboard allows users to get a quick overview of the
status of jobs they're interested in, but more will be added,
e.g. viewing all your jobsets or all jobs of which you're a
maintainer.
There are jobsets that are evaluated only once, that is, after they've
been evaluated, they're disabled automatically. This is primarily
useful for doing releases: for instance, doing an evaluation with
"officialRelease" set to "true" should be done only once.
We can just show the normal "edit jobset" page for the original jobset
and then do a PUT request to create a new jobset.
Also simplified updating the jobset inputs. We can just delete all of
them and recreate them from the user parameters. That's safe because
it's done in a transaction.
It's now a dropdown menu in the tabs thingy, which subsumes the
"Reproduce locally" button. This makes the actions in the menu a bit
more visible, IMHO.
This commit is provided by (zsh syntax):
sed -i 's|/static[^"]*|[% c.uri_for("&") %]|;s/\[% size %\]/${size}/' **/*.tt
And the reason for this change is to make it easier to change the base
path with headers like X-Request-Base to be served within a URI prefix,
especially when behind a reverse proxy.

Each jobset now has a "scheduling share" that determines how much of
the build farm's time it is entitled to. For instance, if a jobset
has 100 shares and the total number of shares of all jobsets is 1000,
it's entitled to 10% of the build farm's time. When there is a free
build slot for a given system type, the queue runner will select the
jobset that is furthest below its scheduling share over a certain time
window (currently, the last day). Withing that jobset, it will pick
the build with the highest priority.
So meta.schedulingPriority now only determines the order of builds
within a jobset, not between jobsets. This makes it much easier to
prioritise one jobset over another (e.g. nixpkgs:trunk over
nixpkgs:stdenv).
Due to the fixed-output derivation hashing scheme, there can be
multiple derivations of the same output path. But build logs are
indexed by derivation path. Thus, we may not be able to find the
log of a build or build step using its derivation. So as a fallback,
Hydra now looks for other derivations with the same output paths.
They're mostly redundant since there is a faster "jobs" tab on
the jobset pages now. The only thing the latter lacks is the
ability to see status change times, but those are quite expensive
to compute, and are visible on build pages if you really need them.
