This is not a behavioral change, as all distros currently use
empty source objects. But when we move over to rpm-based pipelines,
this will change.
Make the same change to osbuild-pipeline, so these stay in sync.

Return errors from all distro's New() functions instead of logging and
returning nil. Also, return errors instead of panicking from
NewRegistry() and NewDefaultRegistry().
WithSingleDistro() doesn't follow go's naming convention for creating
objects (New*). Rename it to NewRegistry() and rename the old
NewRegistry() to NewDefaultRegistry().
The idea is that NewRegistry() can be used to create full Registry
objects from outside the package. NewDefaultRegistry() is a convenience
function that creates a Registry with all known distros.
The current `NewRegistry` implementation allows for nil values in the
map, but this leads to subtle bugs when using the registry. This patch
enforces non-nil values by introducing additional checks before we
insert the value into the map.
The change unfortunately breaks a lot of tests and therefore it is
necessary to create additional mock: distro.
The new mock is used instead of the previous "real" implementation,
which used to contain nil values.
This is unused for now, but will allow us to generate pipelines with
the pre-depsolved NEVRAs, so osbuild does not need to depsolve again.

Rename the package from `pipeline` to `osbuild` to reflect that it
will no longer be specific to pipelines, but rather covers all
osbuild datatypes.

Prior this commit local target copied the image from a worker to a composer
using cp(1) command. This prevented the local target to work on remote
workers.
This commit switches the local target implementation to using the jobqueue
API introduced in the previous commit. I had some concerns about speed
of this solution (imho nothing can beat pure cp(1) implementation) but
ad hoc sanity tests showed the copying of the image using the jobqueue API
when running the worker on the same machine as the composer is still
more or less instant.
Imho it makes more sense from REST perspective. Also, in the future there
will be ROUTE for uploading image to image build. As it's not a good idea
transport file inside JSON, all the parameters (compose id and image
build id) need to be inside the URL. Therefore for the sake of consistency,
all these routes should have compose id and image build id in the URL.
There is another solution to embedding multiple values inside http body
which allows file transport - multipart/form-data. I think using form-data
is worth when doing more complex stuff, for our usecase transporting all
the metadata in the URL is more appropriate solution.
Everything that this field contained can be computed in another way:
- path: just lookup the local target and read the path from there
- mime: can be derived from distribution and compose output type
- size: can be derived from the path
Therefore it imho doesn't make much sense to store these information multiple
times.
The compose will soon move to a concept of including multiple image
builds per one compose, we need to accommodate extra identifier to
handle this scenario.
In the future remote workers will be introduced. Obviously, the remote worker
cannot support the local target. Unfortunately, the current implementation of
storing the osbuild result is dependant on it.
This commit moves the responsibility of storing osbuild result to the
composer process instead of the worker process. The result is transferred from
a worker to a composer using extended HTTP API.
Otherwise if there is an error creating result.json or if the Run
command failed it will remain owned by root.root and cannot be deleted
via the API.
Closes#204
During development of a new distro, we need to test composer against
nightly or beta repositories, but we cannot ship composer itself
with the nightly repository information hardcoded in. At the same
time, we want to distinguish between the system repositories of the
host and the repositories we use to generate images (the host may not
use the same distro/version/architecture as the target, and it may
include custom repositories that the target should not).
We therefore ship per distro repository information that can be
overriden (typically in testing) by dropping files in /etc.
For now use the latest nightlies for RHEL-8.2, we may want to
replace these with the official mirrors for GA eventually.

We were using fedora-30 as a test-distro and tar as test-output, but
that causes lots of churn in the tests when we refactor things. Use
the test distro instead, when generic functionality is being tested
and restrict testing of the individual distros to the distro-specific
tests.

Introduce a DistroRegister object. For now this does not introduce
any functional changes, as the object is always instantited to be
the same. However, in follow-up patches it will get options.

On architectures that require EFI, we must create the ESP partition
and use a GPT partition table. We must also install either the UEFI
or the legacy version of GRUB2 in the image.

The pipeline generation now takes the architecture as an argument.
Currently only x86_64 is supported. The architecture is detected
at start-up, and passed down to each pipeline translation.
For osbuild-pipeline we now requrie the architecture to be passed
in.

Instead of having a static repository checksum, set it dynamically from
the metadata that osbuild-composer last saw. This is implemented in
dnf-json, which returns the checksums for each repository on every call.
This enables the use of repositories that change over time, such as
fedora-updates. Note that the osbuild pipeline will break when such a
repository changes. This is intentional: pipelines have to be
reproducible.
Prior to this commit outputs directory used by local target was owned by root.
This made impossible for osbuild-composer to delete images. (osbuild-composer
doesn't run as root).
This commit introduces state directory in which osbuild-composer creates
outputs directory. Because this directory is owned by osbuild-composer, it's
able to delete files inside.
As a part of f4991cb1 ComposeEntry struct was removed from store package.
This change made sense because this struct is connected more with API than
with store - store uses its own Compose struct. In addition, converters
between Compose and ComposeEntry were added. Unfortunately, ComposeEntry
contains ImageSize which was not stored in Compose but retrieved from store
using GetImage method. This made those converters dependent on the store,
which was messy.
To solve this issue this commit adds image struct into Compose struct.
The content of image struct is generated on the worker side - when the worker
sets the compose status to FINISHED, it also sends Image struct with detailed
information about the result.
RHEL and Fedora used different output formats (.ami vs .raw.xz). The job
package assumed `image.ami`, which failed for RHEL.
Change Fedora to use image.raw.xz as well. This makes it consistent, but
we should also get the filename from the distro at some point.
This commit introduces basic support for upload API. Currently, all the routes
required by cockpit-composer are supported (except for /compose/log).
Also, ComposeEntry struct is moved outside of the store package. I decided
to do it because it isn't connected in any way to store, it's more connected
to API. Due to this move there's currently a known bug that image size is
not returned. This should be solved by moving Image struct inside Compose
struct by follow-up PR.
Make osbuild-composer use FromHost() directly. Everywhere else needs to
specify the distro explicitly.
Also don't panic when a distro doesn't exist. Instead, return nil. Make
sure all callers check for that.
Return the error code of the osbuild run, and an array of errors,
one for each target provided. If a target fails, all other targets
are still attempted.
If either osbuild or one of the targets retursn an error, the worker
notifies osbuild-composer that the job failed.

The helper functions in both api packages were more or less same. However,
over time they have been slowly diverging. This commit extract the helpers
into one common package to make the tests more maintainable and
to deduplicate the code.
