As now we build only when necessary, we need to make sure the images are
built similarly. The discrepancies between the two are less now, and
they can share the same logic.
This fixes a regresion where when no prelude is defined, the build
context isn't copied over
It allows to copy build artifact during buildtime. In this way
artifacts between different seed images can be shared
```
retrieve:
- a-test-1.0.package.*
- https://...
```
They will be available under WORKDIR
Fixes races conditions and make the DB Switchable. Also prepare inside
the CompilationSpec the tree of the deps to be built, and parallelize
only the building jobs.
Closes#7
Signed-off-by: Ettore Di Giacinto <mudler@gentoo.org>
Add CompilationSpecs type to handle slices of CompilationSpec, to
perform operation such as Unique() and Remove().
Add also dependencies and the spec associated to the Artifact, to track
how the artifact was generated.
Add revdeps compilation wrapper, and unit tests
Create compiler interface with switchable backends. For now it can resolve and
parse a `build.yaml` which is in the same folder as in `definition.yaml`
Add also tests to cover this and new fixtures
