Some Hydra API requests were vulnerable to XSRF attacks, e.g. you
could have a form on another website using http://hydra/logout as the
form action. So we now require POST requests to come from the same
origin.
Reported by Hans-Christian Esperer.
Otherwise, the browser may mix up HTML and JSON responses if it has
requested both. For example, hitting the back button to return to a
job metric page will show a JSON response, because that was the last
thing the browser fetched for that URL.
This requires Catalyst::Action::Rest >= 1.20.
The previous query
select count(*) from builds b left join buildsteps s on s.build = b.id where busy = 1 and finished = 0
is suddenly taking several minutes. Probably PostgreSQL decided to use
a suboptimal query plan.
The old page didn't scale very well if you have 150K builds in the
queue, in fact it tended to make browsers hang. The new one just
shows, for each jobset, the number of queued builds. The actual builds
can be seen by going to the corresponding jobset page and looking at
the evals.
The required configuration in hydra.conf:
enable_google_login = 1
google_client_id = 238429sdjkds....apps.googleusercontent.com
and optionally persona_allowed_domains to restrict to one or more
domains.
This removes the "busy", "locker" and "logfile" columns, which are no
longer used by the queue runner. The "Running builds" page now only
shows builds that have an active build step.
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.)
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.
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.
All successful, non-garbage-collected builds in the evaluation are
passed in a attribute set. So if you declare a Hydra input named
‘foo’ of type ‘eval’, you get a set with members ‘foo.<jobname>’. For
instance, if you passed a Nixpkgs eval as an input named ‘nixpkgs’,
then you could get the Firefox build for x86_64-linux as
‘nixpkgs.firefox.x86_64-linux’.
Inputs of type ‘eval’ can be specified in three ways:
* As the number of the evaluation.
* As a jobset identifier (‘<project>:<jobset>’), which will yield the
latest finished evaluation of that jobset. Note that there is no
guarantee that any job in that evaluation has succeeded, so it might
not be very useful.
* As a job identifier (‘<project>:<jobset>:<job>’), which will yield
the latest finished evaluation of that jobset in which <job>
succeeded. In conjunction with aggregate jobs, this allows you to
make sure that the evaluation contains the desired builds.
