precomputed value. Instead, manually check if the value has changed, and if it has, invalidate its consuming WorkspaceStatusValue node, forcing its re-evaluation, where it will pick up the new value.
This seems more awkward than the original code, but it is more correct in spirit: injecting a precomputed value which can change even while the source state does not is a smell. Long-term, the key for the WorkspaceStatusValue should incorporate a hash of the action, and that hash should be in the configuration, just as other configuration flags are. That isn't possible right now just because we don't have configuration trimming, and we drop all nodes on configuration changes, so putting workspace status options into the configuration would lose change pruning whenever we changed workspace status options.
If/when those problems are fixed, we can extend this change to have WorkspaceStatusFunction continue to request the action out-of-band, but keyed by the hash. Then we can stop invalidating stale nodes.

Replace all previous uses of Metadata with FileArtifactValue (or a simple inner
class in the case of ActionCacheChecker.CONSTANT_METADATA).
Care was taken to make the equals method obey the equals contract, even in the
presence of multiple implementations.

Adjust the interface of Metadata to match the interface of FileArtifactValue.
These classes are almost the same, but not quite, so we currently have to
create and return new objects whenever the MetadataHandler is called; by making
the interfaces identical, we can just return a FileArtifactValue instead (in a
future change).
This is in preparation for merging the ActionInputFileCache and MetadataHandler
interfaces.

the currently defined hash function for blobs. Some refactoring. Adding an option to set the hash function in the remote worker, defaulting to the current behavior (unfortunately it is a build option, have not found a clean way to specify it at runtime).

'create' method.
This paves the way for changing PathFragment to e.g. an abstract class with multiple subclasses. This way we can split out the windows-specific stuff into one of these concrete classes, making the code more readable and also saving memory (since the shallow heap size of the NonWindowsPathFragment subclass will hopefully be smaller than that of the current PathFragment).
This also lets us pursue gc churn optimizations. We can now do interning in PathFragment#create and can also get rid of unnecessary intermediate PathFragment allocations.

--noexperimental_enable_critical_path_profiling flags are all specified, then Bazel will delete Actions from ActionLookupValues as they are executed in order to save memory.
Because an already-run action may output an artifact that is only requested later in the build, we need to maintain a way for the artifact to look up the action. But in most cases we don't need to keep the action itself, just its output metadata.
Some actions unfortunately are needed post-execution, and so we special-case them.
Also includes dependency change with description:
Move action out of key. This keeps action references from polluting the graph -- actions are just stored in one SkyValue, instead of being present in SkyKeys.
This does mean additional memory used: we have a separate ActionLookupData object per Action executed. That may reach ~24M for million-action builds.

Except in action execution logic (ActionExecutionFunction, SkyframeActionExecutor, etc.), switch Action interface references to either ActionAnalysisMetadata if possible or ActionExecutionMetadata.
