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.
For users who only have the "create-projects" role, actually display the
item in the menu as the only option.

This reverts commit 2d7e106d29.
Unfortunately some jobsets still depend on this behaviour. They could
probably do something like "assert system == input.system; ..." but
changing them all is undesirable.
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.
If there are builds in the queue that depend on another scheduled
build, then hydra-queue-runner will start the dependency first and
block the dependent builds. This is implemented in
findBuildDependencyInQueue. However, if there are tens of thousands
of such dependent builds, since each call to
findBuildDependencyInQueue may take a second or so, hydra-queue-runner
will spend hours just deciding which builds *not* to do. Thus very
little progress is made.
So now, when a build is started, we immediately check which builds are
"blocked" by it (i.e. depend on it), and remove such builds from
consideration.
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.

Pick the jobset that has used the smallest fraction of its share,
rather than the jobset furthest below its share in absolute terms.
This gives jobsets with a small share a quicker start (but they
will also run out of their share quicker).
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).
In your hydra config, you can add an arbitrary number of <s3config>
sections, with the following options:
* name (required): Bucket name
* jobs (required): A regex to match job names (in project:jobset:job
format) that should be backed up to this bucket
* compression_type: bzip2 (default), xz, or none
* prefix: String to prepend to all hydra-created s3 keys (if this is
meant to represent a directory, you should include the trailing slash,
e.g. "cache/"). Default "".
After each build with an output (i.e. successful or failed-with-output
builds), the output path and its closure are uploaded to the bucket as
.nar files, with corresponding .narinfos to enable use as a binary
cache.
This plugin requires that s3 credentials be available. It uses
Net::Amazon::S3, which as of this commit the nixpkgs version can
retrieve s3 credentials from the AWS_ACCESS_KEY_ID and
AWS_SECRET_ACCESS_KEY environment variables, or from ec2 instance
metadata when using an IAM role.
This commit also adds a hydra-s3-backup-collect-garbage program, which
uses hydra's gc roots directory to determine which paths are live, and
then deletes all files except nix-cache-info and any .nar or .narinfo
files corresponding to live paths. hydra-s3-backup-collect-garbage
respects the prefix configuration option, so it won't delete anything
outside of the hierarchy you give it, and it has the same credential
requirements as the plugin. Probably a timer unit running the garbage
collection periodically should be added to hydra-module.nix
Note that two of the added tests fail, due to a bug in the interaction
between Net::Amazon::S3 and fake-s3. Those behaviors work against real
s3 though, so I'm committing this even with the broken tests.
