- allow to configure the expected job runtime in the test spec
- remove link to EngineConfig and hard-wire the engine latency for now
... extended integration testing reveals two further bugs ;-)
... document deadline calculation
...using hard coded values instead of observation of actual runtimes,
but at least the calculation scheme (now relocated from TimeAnchor to JobPlanning)
should be a reasonable starting point.
TODO: test fails...
PROBLEM: can not implement Spec-generation, since
- we must use a λ for internal allocation of JobTickets
- but recursive type inference is not possible
Will thus need to abandon the Spec-Tuple and relocate this
traversal-and-generation code into JobTicket itself
Use another unit-test (FixtureSegment_test) to guide and cover
the transition from the existing fake-implementation to the
actual implementation, where the JobTicket will be generated
on-demand, from a NodeGraphAttachment
It turns out that the real (not mocked) implementation of JobTicket creation
is already required now for this planned (mock)Dispatcher setup;
moreover, this real implementation turns out to be almost identical
to the mock implementation written recently -- just nested structure
of prerequiste JobTickets need to be changed into a similar structur
of ExitNodes
-- as an aside: rearrange various tests to be more in-line
with the envisioned architecture of playback and engine
...this opens up yet another difficult question and a host of new problems
- how are prerequisites detected or arranged by the Builder
- how are prerequisites represented?
- what is an ExitNode in terms of implementation? A subclass of ProcNode?
- how will the actual implementation of JobTicket creation (on-demand) work?
- how to adapt the Mock implementation, while retaining the Specification
for Segments and prerequisites?
