This adds a `osbuild --version` command that prints the current osbuild
version in use. Allows users to confirm their osbuild is up to date
enough to use newer features.
Now that assemblers are represented via the `Stage` class, the
Assembler class is not needed anymore. Adjust the monitor method
to take an `pipeline.Stage` for the `assembler` method as well.
The 'Manifest' class represents what to build and the necessary
sources to do so. For now thus it is just a combination of the
pipeline the source options.
Instead of importing the load, load_build functions into the osbuild
namespace and using it via that, use the load function via the module
that provides them, i.e. the formats.v1 module.
Extract the code that loads a pipeline from a pipeline description,
i.e. a manifest, into a new module inside a new 'formats' package.
The idea is to have different descriptions, i.e. different formats,
for the same internal representation. This allows changing the
internal representation, i.e. data structures, but still having the
same external description.
Later a new description might be added that better matches the new
internal representation.
This extracts the CLI entrypoint into `main_cli.py` and prepares the
codebase for the introduction of additional entrypoints. This should
not contain any functional changes.
The idea behind this is to add `main_api.py` (and maybe more in the
future), which will be similar to `main_cli.py` but contain the
`osbuild-api` entrypoint. This will make all entrypoints nicely symetric
and the only difference will be `setup.py` selecting the right
entrypoint for each executable, as well as `__main__.py` selecting the
entrypoint for the module itself (which we will keep to the CLI for
compatibility).
A pipeline run only returned logs in the `StageFailed` and
`AssemblerFailed` exceptions. Remove those and always return structured
data instead.
It only returns data for stages that actually ran (i.e., didn't come
from the cache). This is similar to the output in interactive mode.
Also change osbuildtest to be able to deal with output that is larger
than the pipe buffer by using subprocess.communicate().
We've been using a generic `osbuild-run`, which sets up the build
environment (and works around bugs) for all build roots. It is already
getting unwieldy, because it tries to detect the OS for some things it
configures. It's also about to cause problems for RHEL, which doesn't
currently support a python3 shebang without having /etc around.
This patch changes the `build` key in a pipeline to not be a pipeline
itself, but an object with `runner` and `pipeline` keys. `pipeline` is
the build pipeline, as before. `runner` is the name of the runner to
use. Runners are programs in the `runners` subdirectory.
Three runners are included in this patch. They're copies of osbuild-run
for now (except some additions for rhel82). The idea is that each of
them only contains the minimal setup code necessary for an OS, and that
we can review what's needed when updating a build root.
Also modify the `--build-pipeline` command line switch to accept such a
build object (instead of a pipeline) and rename it accordingly, to
`--build-env`.
Correspondingly, `OSBUILD_TEST_BUILD_PIPELINE` → `OSBUILD_TEST_BUILD_ENV`.
Import modules between files using the syntax `from . import foobar`,
renaming what used to be `FooBar` to `foobar.FooBar` when moved to a
separate file.
In __init__.py only import what is meant to be public API.

Make the order of argumnets in line with how it is used (and also
how it is conceptionally closer to the pipeline json document).
This makes no practical difference as the two arguments were both
just used for computing the hash.
