The `storeContext` function was a misguided attempt to performance
optimization. Without storing all the containers and the invalidation
metadata the resume directory would be corrupt by just storing the
context.
Replace the stub implementation of invalidation with the proper
implementation. A ReadPathCache is added to each global so that it can
keep tracks of what target are associated to which read paths.
Add the PipelineDescription object that describes the structure of a
pipeline. This will be used by all the downstream users instead of
pipeline accessor methods via PipelineC.
This commit changes the following method names across the codebase:
* `storeToDisk` -> `store`
* `loadFromDisk` -> `load`
This has been done since the storage is no longer bound to the local
storage.
Move much of the logic of `rp_manager_produce_targets` to a method
inside `PipelineManager`, add additional checks for the existence of the
targets that are requested to be produced.
`recalculateAllPossibleTarget` is now a private member of
PipelineManager This was done since all calls that can trigger a change
in the target list have been isolated and the call is done implicitly.
This removes rp_manager_recompute_all_available_targets from PipelineC,
since it was added as a stopgap until the above was implemented.
This commit introduces some changes to how the revng pipeline handles
serializing to disk. Specificaly:
* Pipeline globals (specifically model.yml) are better handled if they
are in a subdirectory. They are now saved in the "context"
subdirectory.
* In python:revng.api the pipeline is serialized whenever there is a
non-reproducible change to the state (e.g. binary upload or model
change).
In the case of analyses this is done conservatively by checking that
the diff produced is not empty.
* The logic for computing a step's subdirectory has been moved to the
pipeline runner, consequently if a step is asked to serialize it
will not create any subdirectories.
* Functionality for saving a single step/context has been exposed in
Pipeline C.
* Finally, all path concatenations are now handled by
llvm::sys::path::append, for extra os-agnosticism.
This commit imports all the revng pipes (and other support utilities) to
be used with `revng-pipeline`. In particular, the pipes necessary for
binary translations have been introduced.
