There is still a tiny window between the calls to nix-prefetch-* and
addTempRoot. This could be eliminated by adding a "-o" option to
nix-prefetch-*, or by not using those scripts at all (and use
addToStore directly).
This allows Hydra to use binaries from available binary caches. It
makes the queue monitor thread quite a bit slower, so if you don't
want to use binary caches, it's better to add "--option
build-use-substitutes false" to the hydra-queue-runner invocation.
Fixed#243.
The last paragraph states about package installation of the "following"
jobs, but it only applies to generic channels, so let's only display it
there.

So this is the final part which is needed in order to be able to deliver
custom channels, everything else is now just polishing.
We do this by simply redirecting to the build product download URL and
we use binary_cache_url the same way as in NixChannel.pm.

We should now get an overview and help text on how to add a particular
channel and also a bit of information about the builds that are required
for a channel to get upgraded.
Right now we only select the latest successful build in the latest
successful evaluation, so if someone wants to have more information about
which channel has failed, (s)he still has to look at the "Channels" tab
of the jobset.
We can make this more fancy at some later point if this is really
needed, because right now we're only interested in the latest build,
because it's the only thing necessary to deliver the channel contents.

It's actually lower-case _despite_ the spelling in the SQL file(s),
because the schema auto-generator from DBIx::Class doesn't take it into
account because it's working on SQLite and the latter seems to ignore
case.

We want to have contents and detauls of channel expressions as well and
we already have that in product.type == file, so why not reuse the same
for the channel expression?
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
We now have a searchBuildsAndEvalsForJobset, which creates such a
mapping for us, so we don't need to duplicate code in jobs_tab and
channels_tab.
Also, we're going to use this for the overview of a particular channel
as well, so it makes sense to put it in CatalystUtils instead of
directly in Jobset.pm.
Instead of eval->jobs, it's now eval->builds, because it's really an
aggregate over the builds schema, rather than the job schema.

We only allow channel/latest anyway, so it really doesn't make sense to
explicitly specify this in the PathPart and provide other dispatcher
once we have more than just "latest", which greatly simplifies the
dispatch tree.

We now have a column for that, so no need for counting rows which was a
bit inefficient anyway, because we only would have needed the first row
in the result.

Now that we have our dedicated "Channels" tab, there is no need anymore
to show redundant information.

We now no longer need that additional join of the build outputs and can
solely use the isChannel column of the Builds table to determine whether
it's a channel build.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
This is to properly separate channels from regular jobs and also make
sure that we can always iterate on them, no matter whether the build has
failed. The reason why we were not able to do this until now was because
we were iterating on the build products, and whenever some constituent
of a channel job has failed, we didn't get a build output.
So whenever there is a meta.isHydraChannel, we can now properly
distinguish it from the other jobs.
I still don't have any clue, why "make -C src/sql update-dbix" without
*any* modifications tries to create additional schema definitions. But
I've checked the md5sums of the existing schema definitions and they
don't seem to match, so it seems that they already have been tampered
with.

Now we can provide different channel expressions for one particular
channel build. Not sure yet how this would be useful, but I found it
more appropriate to use a type instead of a subtype of "file".
This should get us consistent with the provious commit.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
This is to get a bit more consistency among channel builds but doesn't
do a radical change on the display. Ideally we may want to have a
channel overview with all the constituents and a small help showing how
the user can add the channel.
Unfortunately, this also introduces an inconsistency: We previously used
the *subtype* "channel", but now we're expecting "channel" as the type
of the product, so we need to change this for the channels overview as
well.

It's very similar to "jobs" and the code is pretty much the same, except
that we don't do filtering on it. At least it doesn't waste space for a
filter option when there are usually WAY less channel jobs than ordinary
jobs.

Currently I'm using a (not very well) downscaled version of the NixOS
logo, so we want to replace it by a proper image ASAP.
Other than that, the idea is to have something like this in
hydra-build-products:
file channel $out/channel.tar.bz2
Right now of course, it's only displayed at the corresponding builds, so
we might want to have aggregates on all channels for a project, jobset
or maybe even single jobs?

They will show up in machineTypes as (e.g.) x86_64-linux:local instead
of x86_64-linux. This is to prevent the Hydra provisioner from
creating machines for steps that are supposed to be executed locally.
It's easier for the Hydra provisioner to put host public keys in the
machines file than to separately manage the known_hosts file
(especially when the provisioner runs on a different machine).
This is necessary because the required system type can become
available later (e.g. by being provisioned by the
auto-scaler). However, in the future, we may want to fail steps if
they have been unsupported for more than a certain amount of time.
For example, steps that require the "kvm" feature may require a
different kind of machine to be provisioned. This can also be used to
require performance-sensitive tests to run on a particular kind of
machine, e.g., by setting requiredSystemFeatures to something like
"ec2-i2.8xlarge".
"hydra-queue-runner --status" now prints how many runnable and running
build steps exist for each machine type. This allows additional
machines to be provisioned based on the Hydra load.
