This patch implements the feature to be able to pass author and commit hash
information from the repository to the container.
This can be used to set packager or package description commit hash inside the
build container, if desired.

This patch refactors the collecting of the environment variables in the
`RunnableJob::build_from_job()` implementation as well as in the
`RunnableJob::environemtn()` implementation.
This results in fewer allocations, especially but not only because the
`RunnableJob::environment()` function returns an iterator now and all clone()
calls were removed.

This patch follows-up on the shrinking of the `Artifact` type and removes it
entirely.
The type is not needed. Only the `ArtifactPath` type is needed, which is a thin
wrapper around `PathBuf`, ensuring that the path is relative to the store root.
The `Artifact` type used `pom` to parse the name and version of the package from
the `ArtifactPath` object it contained, which resulted in the restriction that
the path must always be
<name>-<version>...
Which should not be a requirement and actually caused issues with a package
named "foo-bar" (as an example).

This functionality is not required anymore, as we put the whole package
definition in the job script interpolation anyways.

This patch reimplements the running of the computed jobs.
The old implementation was structured as follows:
1. Compute a Tree of dependencies for the requested package
2. Make sets of this tree (see below)
3. For each set
3.1. Run set in parallel by submitting each job in the set to the scheduler
3.2. collect outputs and errors
3.3. Record outputs and return errors (if any)
The complexity here was the computing of the JobSets but also the running of
each job in a set in parallel.
The code was non-trivial to understand.
But that's not even the biggest concern with this approch.
Consider the following tree of jobs:
A
/ \
B E
/ \ \
C D F
/ \
G H
\
I
Each node here represents a package, the edges represent dependencies on the
lower-hanging package.
This tree would result in 5 sets of jobs:
[
[ I ]
[ G, H ]
[ C, D, F ]
[ B, E ]
[ A ]
]
because each "layer" in the tree would be run in parallel.
It can be easily seen, that in the tree from above, the jobs for [ I, G, D, C ]
can be run in parallel easily, because they do not have dependencies.
The reimplementation also has another (crucial) benefit: The implementation does
not depend on a structure of artifact path names anymore.
Before, the artifacts needed to have a name as follows:
<name of the package>-<version of the package>.<something>
which was extremely restrictive.
With the changes from this patch, the implementation does not depend on such
a format anymore.
Instead: Dependencies are associated with a job, by the output of jobs run
for dependent packages.
That means that, considering the above tree of packages:
deps_of(B) = outputs_of(job_for(C)) + outputs_of(job_for(D))
in text:
The dependencies of package B are the outputs of the job run for package C
plus the outputs of the job run for package D.
With that change in place, the outputs of a job run for a package can yield
arbitrary file names and as long as the build script for the package can process
them, everything is fine.
The new algorithm, that solves that issue, is rather simple:
1. Hold a list of errors
2. Hold a list of artifacts that were built
3. Hold a list of jobs that were run
4. Iterate over all jobs, filtered by
- If the job appears in the "already run jobs" list, ignore it
- If a job has dependencies (on outputs of other jobs) that do not appear in
the "already run jobs", ignore it (for now)
5. Run these jobs, and for each job:
5.1. Take the job UUID and put it in the "already run jobs" list.
5.2. Take the result of the job,
5.2.1. if it is an error, put it in the "list of errors"
5.2.2. if it is ok, put the artifact in the "list of artifacts"
6. if the list of errors is not empty, goto 9
7. if all jobs are in the "already run jobs" list, goto 9
8. goto 4
9. return all artifacts and all errors
Because this approach is fundamentally different than the previous approach, a
lot of things had to be rewritten:
- The `JobSet` type was complete removed
- There is a new type `crate::job:Tree` that gets built from the
`crate::package::Tree`
It is a mapping of a UUID (the job UUID) to a `JobDefinition`.
The `JobDefinition` type is
- A Job
- A list of UUIDs of other jobs, where this job depends on the outputs
It is therefore a mapping of `Job -> outputs(jobs_of(dependencies)`
The `crate::job::Tree` type is now responsible for building a `Job` object for
each `crate::package::Package` object from the `crate::package::Tree` object.
Because the `crate::package::Tree` object contains all required packages for
the complete built, the implementation of `crate::job::Tree::build_tree()`
does not check sanity.
It is assumed that the input tree to the function contains all mappings.
Despite the name `crate::job::Tree` ("Tree"), the actual structure stored in
the type is not a real tree.
- The `MergedStores::get_artifact_by_path()` function was adapted because in the
previous implementation, it used `StagingStore::load_from_path()`, which tried
to load the file from the filesystem and put it into the internal map, which
failed if it was already there.
The adaption checks if the artifact already exists in the internal map and
returns that object instead.
(For the release store accordingly)
- The interface of the `RunnableJob::build_from_job()` function was adapted, as
this function does not need to access the `MergedStores` object anymore to
load dependency-Artifacts from the filesystem.
Instead, these Artifacts are passed to the function now.
- The Orchestrator code
- Got a type alias `JobResult` which represents the result of a job run wich
is either
- A number of artifacts (for optimization reasons with their associated
database artifact entry)
- or an error with the job uuid that failed (again, for optimization
reasons)
- Got an implementation of the algorithm described above
- Got a new implementation of run_job(), which
- Fetches the pathes of dependency-artifacts from the database by using
the job uuids from the JobDefinition object
- Creates the RunnableJob object for that
- Schedules the RunnableJob object in the scheduler
- For each output artifact (database object representing it)
- get the filesystem Artifact object for it

This improves the collection building be reducing the asyncness.
The stream is build first and then all futures are collected. Before
this patch, two streams were collected and then appended.
Not sure whether this improves runtime, but it certainly improves
readability.
Unfortunately, collecting the additional job resources right into the
streams is not that easy and thus the resulting collection is simply
extend()ed.

This patch adds strict script interpolation, which means that the script
interpolation will result in an error if a variable is referenced that
does not exist.
Before this patch, referencing an absent variable did result in an empty
string, possibly resulting in an error at runtime.
This feature is on by default.

This patch implements multiple (unnamed) sources per package.
This means that a package can have an array of sources.
What was adapted to allow multiple sources per package:
* Downloads are made in parallel now
* The cache structure was changed to /<package>-<version>/<hash>.source
* The UI was changed to contain the full `Package` struct (as JSON
object) in a UI format string
Tests were adapted.

This patch rewrites the codebase to not use std::sync::RwLock, but
tokio::sync::RwLock.
tokios RwLock is an async RwLock, which is what we want in an
async-await context. The more I use tokio, the more I understand what
you should do and what you shouldn't do.
Some parts of this patch are a rewrite, for example,
JobSet::into_runables()
was completely rewritten.
That was necessary because the function used inside is
`Runnable::build_from_job()`, which uses an RwLock internally, thus,
gets `async` in this patch.
Because of this, `JobSet::into_runables()` needed a complete rewrite as
well.
Because it is way more difficult than transforming the function to
return an iterator of futures, this patch simply rewrites it to return a
`Result<Vec<RunnableJob>>` instead.
Internally, tokio jobs are submitted via the
`futures::stream::FuturesUnordered<_>` now.
This is not the most performant implementation for the problem at hand,
but it is a reasonable simple one. Optimization could happen here, of
course.
Also, the implementation of resource preparation inside
`RunnableJob::build_from_job()` got a rewrite using the same technique.

This patch adds the runtime dependencies into the runnable job.
These might be required to execute tests for a package inside the
container.
Because of this we also copy them to the container.
The patch also generalizes the preparing mechansim into a helper
function and makes use of some nice iterator chaining to be more
readable.
