Port sources to also use the host services infrastructure that is
used by inputs, devices and mounts. Sources are a bit different
from the other services that they don't run for the duration of
the stage but are run before anything is built. By using the same
infrastructure we re-use the process management and inter process
communcation. Additionally, this will forward all messages from
sources to the existing monitoring framework.
Adapt all existing sources and tests.
This moves the check for already downloaded files earlier so
that if all files are already downloaded we don't need to
load the secrets.
This is faster, but also it allows a pre-seeded object store
to run the manifest on a system (like a VM) that isn't subscribed.
The previous version covered too few use cases, more specifically a
single subscription. That is of course not the case for many hosts, so
osbuild needs to understand subscriptions.
When running org.osbuild.curl source, read the
/etc/yum.repos.d/redhat.repo file and load the system subscriptions from
there. While processing each url, guess which subscription is tied to
the url and use the CA certificate, client certificate, and client key
associated with this subscription. It must be done this way because the
depsolving and fetching of RPMs may be performed on different hosts and
the subscription credentials are different in such case.
More detailed description of why this approach was chosen is available
in osbuild-composer git: https://github.com/osbuild/osbuild-composer/pull/1405
Now that there is a common utility function to verify the checksum
of a file, use that.
Also fix the json schema entry for the property to have to correct
minium and maximum digest length, given the supported algorithm,
which is 32 (md5) and 128 (sha512) characters.
Since the `sources.SourcesServer` has been removed, nothing is
using the export functionality anymore. Inputs are now used to
make content in the store available to stages. Remove all the
export logic from org.osbuild.curl.
The `org.osbuild.files` source provides files, but might in the
future not be the only one that does. Therefore rename it to
match the internal tool that is being used to fetch the files.
This is done for most other osbuild modules that target tools.
The format v1 loader is adapted to make this change transparent
for users of the v1 format, so we are backwards compatible.
Change the MPP depsolve preprocessor so that for format v2 based
manifest `org.osbuild.curl` source is used. Also rename the
corresponding source test. Adapt the format v2 mod test to use
the curl source.
