Add a `Dirty` boolean to the `ContainerBase` class. This will be set to
true when the container mutates itself (e.g. remove, mergeBack, clear).
The dirty bit is reset when running `PipelineManager.store`.
Implement the pruning of container caches (resume directory) when there
is a mismatch between the current revng components' hash and the saved
one. This functionality is activated via `-check-components-version`.
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.
This commit introduces the concept of `Component` to a pipeline step.
This, in turn, can be used by clients to figure out which artifacts are
produced by which revng component.
Additionally, this commit overhauls the `revng daemon-self-test`
command, renaming it to `revng graphql` and adding extra flexibility.
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.
